Abstract
BACKGROUND The parent-proxy paediatric chronic cough quality of life questionnaire (PC-QoL) is a commonly used measure of spillover quality of life in parents of children with chronic cough. To date, spillover health utility in these parents is not routinely estimated largely due to the lack of a suitable instrument. Their perspective is not included in economic evaluations of interventions for their children. We explored developing a health state classification system based on the PC-QoL for measuring health utility spill over in this population. METHODS This study included PC-QoL 8-item responses of 653 parents participating in a prospective cohort study about paediatric chronic cough. Exploratory factor analysis (EFA) and Rasch analysis were used to examine dimensionality and select potential items and level structure. RESULTS EFA indicated that the PC-QoL had one underlying domain. Rasch analysis indicated threshold disordering in all items which improved when items were collapsed from seven to four levels. Two demonstrated differential item functioning (DIF) by diagnosis or ethnicity and were excluded from the final scale. This scale satisfied Rasch assumptions of local independence and unidimensionality and demonstrated acceptable fit to the Rasch model. It was presented to and modified by an expert panel and a consumer panel. The resulting classification system had six items, each with four levels. DISCUSSION The PC-QoL can conform to a Rasch model with minor modifications. It may be a good basis for the classification system of a child cough-specific PBM. A valuation study is required to estimate preference weights for each item and to estimate health utility in parents of children with chronic cough.

Consumer Preferences for a Healthcare Appointment Reminder in Australia: A Discrete Choice Experiment. THE PATIENT 2024:10.1007/s40271-024-00692-9. [PMID: 38605246 DOI: 10.1007/s40271-024-00692-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 03/18/2024] [Indexed: 04/13/2024]
Abstract
BACKGROUND It is essential to consider the evidence of consumer preferences and their specific needs when determining which strategies to use to improve patient attendance at scheduled healthcare appointments. OBJECTIVES This study aimed to identify key attributes and elicit healthcare consumer preferences for a healthcare appointment reminder system. METHODS A discrete choice experiment was conducted in a general Australian population sample. The respondents were asked to choose between three options: their preferred reminder (A or B) or a 'neither' option. Attributes were developed through a literature review and an expert panel discussion. Reminder options were defined by four attributes: modality, timing, content and interactivity. Multinomial logit and mixed multinomial logit models were estimated to approximate individual preferences for these attributes. A scenario analysis was performed to estimate the likelihood of choosing different reminder systems. RESULTS Respondents (n = 361) indicated a significant preference for an appointment reminder to be delivered via a text message (β = 2.42, p < 0.001) less than 3 days before the appointment (β = 0.99, p < 0.001), with basic details including the appointment cost (β = 0.13, p < 0.10), and where there is the ability to cancel or modify the appointment (β = 1.36, p < 0.001). A scenario analysis showed that the likelihood of choosing an appointment reminder system with these characteristics would be 97%. CONCLUSIONS Our findings provide evidence on how healthcare consumers trade-off between different characteristics of reminder systems, which may be valuable to inform current or future systems. Future studies may focus on exploring the effectiveness of using patient-preferred reminders alongside other mitigation strategies used by providers.

Comparison of the Early Childhood Oral Health Impact Scale (ECOHIS-4D) and Child Health Utility Index (CHU-9D) in children with oral diseases. Community Dent Oral Epidemiol 2024; 52:224-231. [PMID: 37811777 DOI: 10.1111/cdoe.12917] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Revised: 08/09/2023] [Accepted: 09/25/2023] [Indexed: 10/10/2023]
Abstract
OBJECTIVE Accurate assessment of child oral health is important for guiding economic evaluations and informing healthcare decision-making. Early Childhood Oral Health Impact Scale (ECOHIS-4D) is a preference-based instrument that measures the oral health-related quality of life of young children. The aim of this study was to compare the utility scores of ECOHIS-4D and Child Health Utility Index (CHU-9D), against an oral health indicator to evaluate which utility score corresponds better with the oral health indicator. METHOD The ECOHIS-4D and CHU-9D were applied to 314 parent/child dyads from preschools in a primary healthcare setting in Perth, Western Australia. Four parameters were used to assess which instrument corresponds better with the oral health indicator (decayed, missing and filled teeth score-dmft score): (i) discrimination, the ability to discriminate between different clinical severity groups, (ii) external responsiveness, how much the utility values relate to the changes in dmft scores, (iii) correlation, the association between the two instruments and the related dimensions and (iv) differences in the utility values across the two instruments. RESULTS Most participants (81%) were 2-6 years old, and nearly 50% had a dmft score <3. ECOHIS-4D demonstrated a superior ability to differentiate between dmft severity groups and respond to changes in dmft scores. A significant weak correlation was observed between dmft and ECOHIS-4D (-0.26, 95%, CI -0.36 to -0.15) compared to a non-significant very poor correlation between dmft and CHU-9D (0.01, 95% CI -0.12 to 0.10). The utility scores of the two instruments had relatively good agreement towards good health and weak agreement towards poor health. CONCLUSIONS ECOHIS-4D, the oral health-specific instrument, is more sensitive in assessing children's oral health-related quality of life than the generic CHU-9D. Thus, ECOHIS-4D is more appropriate for utility estimates in economic evaluations of oral health-related interventions and resource allocation decision-making.

Financial Aid in Children, Adolescents and Young Adult's Cancer Care: A Scoping Review. J Adolesc Young Adult Oncol 2024. [PMID: 38451723 DOI: 10.1089/jayao.2023.0134] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 03/09/2024] Open
Abstract
Background: The financial burden resulting from cancers on families is higher when it arises in young people compared with older adults. Previous research has provided insight into the financial toxicities associated with childhood cancer, but less is known about the efficacy of financial aid systems in reducing the financial burden on families. We conducted a scoping review to identify the determinants of success and failure of financial aid. Methods: Five databases were searched for articles published between January 1, 2000 and December 1, 2022. Dual processes were used to screen and select studies. Through thematic content analysis, we identified barriers and enablers of financial aid, categorised by country income level. Results: From 17 articles, which were evenly split between high-income countries and upper middle- to low-income countries, four major themes emerged: (1) accessibility of support, (2) delivery of support, (3) administration, and (4) psychosocial factors. Within these themes, the enablers identified were (1) support navigators, (2) establishing a direct contact between donors and beneficiaries, (3) implementation of digital solutions to improve outreach, and (4) using cultural and community values to encourage donor engagement. Conclusions: This scoping review identified the determinants of success and failure of financial aid in supporting families in the context of childhood, adolescent, and young adult (CAYA) cancers. By understanding the barriers and enablers identified in this review, organizations could develop pragmatic evidence-based care models and policies to ensure access to assistance is equitable and appropriate for families experiencing CAYA cancers.

A discrete choice experiment to elicit preferences for a chronic disease screening programme in Queensland, Australia. Public Health 2024; 228:105-111. [PMID: 38354579 DOI: 10.1016/j.puhe.2024.01.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 12/25/2023] [Accepted: 01/09/2024] [Indexed: 02/16/2024]
Abstract
OBJECTIVE Patient-centred care, increasingly highlighted in healthcare strategies, necessitates understanding public preferences for healthcare service attributes. We aimed to understand the preferences of the Australian population regarding the attributes of chronic disease screening programmes. STUDY DESIGN The preferences were elicited using the discrete choice experiment (DCE) methodology. METHODS A DCE was administered to a sample of the Australian general population. Respondents were asked to make choices, each offering two hypothetical screening scenarios defined by screening conduct, quality and accuracy of the test results, cost to the patient, wait time and source of information. Data were analysed using a panel mixed multinomial logit model. RESULTS A strong preference for highly accurate screening tests and nurse-led screenings at local health clinics was evident. They expressed disutility for waiting time and out-of-pocket costs but were indifferent about the source of information. Their preference for a nurse-led programme was highlighted by the fact that they were willing to pay $81 and $88 to get a nurse-led programme when they were offered a general practitioner-led and a specialist-led programme, respectively. Furthermore, they were willing to pay $32 to reduce a week of waiting time and $205 for a 95% accurate test compared to a 75% accurate test. Preferences remained consistent irrespective of the respondent's place of residence. CONCLUSIONS Our findings highlight the importance of diagnostic test accuracy and nurse-led service delivery in chronic disease screening programmes. These insights could guide the development of patient-centric services by enhancing test accuracy, reducing waiting times and promoting nurse-led care models.

Long-term Patient and Health Service Outcomes of Ablation and Antiarrhythmic Drugs in Atrial Fibrillation: A Comparative Systematic Review. Cardiol Rev 2024; 32:162-169. [PMID: 36730485 DOI: 10.1097/crd.0000000000000493] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/04/2023]
Abstract
Atrial fibrillation (AF) is a prevalent problem worldwide and a common cause of hospitalization, poor quality of life, and increased mortality. Although several treatments are used, the use of ablation and antiarrhythmic drug therapy has increased in the past decade. However, debate continues on the most suitable option for heart rhythm control in patients. Previous studies have largely focused on short-term outcome effects of these treatments. This systematic review aims to determine the effect of ablation compared to antiarrhythmic drugs for AF on long-term patient and health service outcomes of mortality, hospitalization, and quality of life. Three databases were systematically searched-studies were included if they reported long-term outcomes of more than 12 months comparing the 2 treatments. Title and abstract screening and subsequent full-text screening was done by 2 reviewers. Data were extracted from the final studies identified. The details of the search were recorded according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses report. A total of 2224 records were identified. After removing duplicates and screening the titles and abstracts, 68 records required full-text screening. Finally, 12 papers were included in the analysis. Eight studies reported mortality indicating ablation was superior, 2 studies reported hospitalization with opposing outcomes, and 5 quality of life studies indicating ablation was a better treatment. In studies assessing long-term outcomes, beyond 12 months, following ablation or rhythm control drugs for AF, most found a lower risk of death and greater improvement in quality of life in the ablation group.

Implementing neurodevelopmental follow-up care for children with congenital heart disease: A scoping review with evidence mapping. Dev Med Child Neurol 2024; 66:161-175. [PMID: 37421232 PMCID: PMC10953404 DOI: 10.1111/dmcn.15698] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 05/04/2023] [Accepted: 06/07/2023] [Indexed: 07/10/2023]
Abstract
AIM To identify and map evidence describing components of neurodevelopmental follow-up care for children with congenital heart disease (CHD). METHOD This was a scoping review of studies reporting components of neurodevelopmental follow-up programmes/pathways for children with CHD. Eligible publications were identified through database searches, citation tracking, and expert recommendations. Two independent reviewers screened studies and extracted data. An evidence matrix was developed to visualize common characteristics of care pathways. Qualitative content analysis identified implementation barriers and enablers. RESULTS The review included 33 studies. Twenty-one described individual care pathways across the USA (n = 14), Canada (n = 4), Australia (n = 2), and France (n = 1). The remainder reported surveys of clinical practice across multiple geographical regions. While heterogeneity in care existed across studies, common attributes included enrolment of children at high-risk of neurodevelopmental delay; centralized clinics in children's hospitals; referral before discharge; periodic follow-up at fixed ages; standardized developmental assessment; and involvement of multidisciplinary teams. Implementation barriers included service cost/resourcing, patient burden, and lack of knowledge/awareness. Multi-level stakeholder engagement and integration with other services were key drivers of success. INTERPRETATION Defining components of effective neurodevelopmental follow-up programmes and care pathways, along with enhancing and expanding guideline-based care across regions and into new contexts, should continue to be priorities. WHAT THIS PAPER ADDS Twenty-two different neurodevelopmental follow-up care pathways/programmes were published, originating from four countries. Twelve additional publications described broad practices for neurodevelopmental follow-up across regions Common attributes across eligibility, service structure, assessment processes, and care providers were noted. Studies reported programme acceptability, uptake, cost, and effectiveness. Implementation barriers included service cost/resourcing, patient burden, and lack of knowledge/awareness.

Disability, equity, and measurements of livability: A scoping review. Disabil Health J 2024; 17:101521. [PMID: 37722993 DOI: 10.1016/j.dhjo.2023.101521] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 08/22/2023] [Accepted: 08/23/2023] [Indexed: 09/20/2023]
Abstract
BACKGROUND Livability is a concept commonly featured in health research to help shape public policy decisions and improve local place settings. Although widely used, it is a contested concept known for its ambiguity and inconsistency of measurements. Other criticisms include the lack of equity perspectives and the underrepresentation of people with disabilities and inhabitants of non-metropolitan places. OBJECTIVES This review sought to identify the extent to which people with disabilities and non-metropolitan places are included in measurements of livability and to critically review and summarise i) livability definitions and uses, ii) livability places and populations, and iii) livability measurements. METHODS The scoping review followed Arksey and O'Malley's methodological framework and the PRISMA extension for scoping reviews. The data extraction used meta-aggregation techniques to evaluate findings. A standardised mixed methods appraisal tool was used, and a novel classification of measurements was created. RESULTS Seventy-seven articles were included, and 1955 measurements were extracted. The overarching findings were: i) livability is inconsistently defined and assessed by measuring the performance of related and independent domains, ii) the population sample or the studies' participants are often not disclosed, non-metropolitan settings are overlooked, and equity is not generally applied or operationalised in measurements, and iii) there is an extensive lack of measurements considering people with disabilities and diversity within disabilities. CONCLUSIONS The assumptions of homogeneity in study populations in livability measurement literature overlook inequities experienced by people with disabilities and inhabitants of non-metropolitan settings. This review suggests recommendations for future research to assess livability from perspectives inclusive of human diversity.

The Economic Burden of Bronchiectasis: A Systematic Review. Chest 2023; 164:1396-1421. [PMID: 37423293 DOI: 10.1016/j.chest.2023.06.040] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 04/20/2023] [Accepted: 06/19/2023] [Indexed: 07/11/2023] Open
Abstract
BACKGROUND Bronchiectasis, a previously neglected condition, now has renewed research interest. There are a few systematic reviews that have reported on the economic and societal burden of bronchiectasis in adults, but none have reported on children. We undertook this systematic review to estimate the economic burden of bronchiectasis in children and adults. RESEARCH QUESTION What is the health care resource utilization and economic burden of bronchiectasis in adults and children? STUDY DESIGN AND METHODS We performed a systematic review identifying publications from Embase, PubMed, Web of Science, Cochrane (trials, reviews, and editorials), and EconLit about the economic burden and health care utilization in adults and children with bronchiectasis between January 1, 2001, and October 10, 2022. We used a narrative synthesis approach and estimated aggregate costs for several countries. RESULTS We identified 53 publications reporting on the economic burden and/or health care utilization of people with bronchiectasis. Total annual health care costs per adult patient ranged from 2021 $3,579 to $82,545 USD and were predominantly driven by hospitalization costs. Annual indirect costs including lost income because of illness (reported in only five studies) ranged from $1,311 to $2,898 USD. Total health care costs in children with bronchiectasis were $23,687 USD annually in the one study that estimated them. Additionally, one publication found that children with bronchiectasis missed 12 school days per year. We estimated aggregate annual health care costs for nine countries, ranging from $101.6 million per year in Singapore to $14.68 billion per year in the United States. We also estimated the aggregate cost of bronchiectasis in Australian children to be $17.77 million per year. INTERPRETATION This review highlights the substantial economic burden of bronchiectasis for patients and health systems. To our knowledge, it is the first systematic review to include the costs for children with bronchiectasis and their families. Future research to examine the economic impact of bronchiectasis in children and economically disadvantaged communities, and to further understand the indirect burden of bronchiectasis on individuals and the community, is needed.

Oral Health, Social and Emotional Well-Being, and Economic Costs: Protocol for the Second Australian National Child Oral Health Survey. JMIR Res Protoc 2023; 12:e52233. [PMID: 37962928 PMCID: PMC10691528 DOI: 10.2196/52233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 08/29/2023] [Accepted: 08/30/2023] [Indexed: 11/15/2023] Open
Abstract
BACKGROUND Given the significant investment of governments and families into the provision of child dental care services in Australia, continued population oral health surveillance through national oral health surveys is imperative. OBJECTIVE The aims of this study are to conduct a second National Child Oral Health Survey (NCOHS-2) to (1) describe the prevalence, extent, and impact of oral diseases in contemporary Australian children; (2) evaluate changes in the prevalence and extent of oral diseases in the Australian child population and socioeconomic subgroups since the first National Child Oral Health Study (NCOHS-1) in 2012-2013; and (3) use economic modeling to evaluate the burden of child oral disease from the NCOHS-1 and NCOHS-2 and to estimate the cost-effectiveness of targeted programs for high-risk child groups. METHODS The NCOHS-2 will closely mimic the NCOHS-1 in being a cross-sectional survey of a representative sample of Australian children aged 5-14 years. The survey will comprise oral epidemiological examinations and questionnaires to elucidate associations between dental disease in a range of outcomes, including social and emotional well-being. The information will be analyzed within the context of dental service organization and delivery at national and jurisdictional levels. Information from the NCOHS-1 and NCOHS-2 will be used to simulate oral disease and its economic burden using both health system and household costs of childhood oral health disease. RESULTS Participant recruitment for the NCOHS-2 will commence in February 2024. The first results are expected to be submitted for publication 6 months after NCOHS-2 data collection has been completed. Thematic workshops with key partners and stakeholders will also occur at this time. CONCLUSIONS Regular surveillance of child oral health at an Australian level facilitates timely policy and planning of each state and territory's dental public health sector. This is imperative to enable the most equitable distribution of scarce public monies, especially for socially disadvantaged children who bear the greatest dental disease burden. The last NCOHS was conducted in 2012-2014, meaning that these data need to be updated to better inform effective dental health policy and planning. The NCOHS-2 will enable more up-to-date estimates of dental disease prevalence and severity among Australian children, with cost-effective analysis being useful to determine the economic burden of poor child dental health on social and emotional well-being and other health indicators.

Abstract
BACKGROUND Indigenous Australian children and adolescents experience profound levels of preventable dental disease. The application of silver fluoride (AgF) to active dental caries is a noninvasive alternative to traditional dental treatment approaches. There is particular utility among Indigenous children and young people with dental fear, who may not have access to timely or culturally safe dental service provisions. OBJECTIVE The aims of this study are to: (1) assess levels of active dental caries among Indigenous children and young people in 6 Australian states and territories; (2) determine if an AgF intervention reduces levels of active disease over 12-24 months; (3) measure the impact of improved oral health on social and emotional well-being (SEWB) and oral health-related quality of life; and (4) calculate the cost-effectiveness of implementing such an initiative. METHODS The study will use a 2-arm, parallel cluster randomized controlled trial design. Approximately 1140 Indigenous children and youth aged between 2 and 18 years will be recruited. Each state or territory will have 2 clusters. The intervention group will receive the AgF intervention at the start of the study, with the delayed intervention group receiving the AgF intervention 12 months after study commencement. The primary outcome will be the arrest of active carious lesions, with arrested caries defined as nonpenetration by a dental probe. Secondary outcomes will include SEWB, oral health-related quality of life, and dental anxiety, with covariates including dental behaviors (brushing and dental visits). Effectiveness measures for the economic evaluation will include the number of children and young people managed in primary oral health care without the need for specialist referral, changes in SEWB, the numbers and types of treatments provided, and caries increments. RESULTS Participant recruitment will commence in May 2023. The first results are expected to be submitted for publication 1 year after a 24-month follow-up. CONCLUSIONS Our findings have the potential to change the way in which active dental disease among Indigenous children and young people can be managed through the inclusion of specifically tailored AgF applications to improve dental health and SEWB delivered by Indigenous health care workers. Desired impacts include cost savings on expensive dental treatments; improved SEWB, nutrition, social, and learning outcomes; and improved quality of life for both children and young people and their caregivers and the broader Indigenous community. The AgF application could be easily implemented into the training program of Indigenous health workers and yield critical information in the management armamentarium of health and well-being recommendations for Australia's First Peoples.

Developing an Australian utility value set for the Early Childhood Oral Health Impact Scale-4D (ECOHIS-4D) using a discrete choice experiment. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2023; 24:1285-1296. [PMID: 36394684 PMCID: PMC10533628 DOI: 10.1007/s10198-022-01542-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2022] [Accepted: 10/14/2022] [Indexed: 06/16/2023]
Abstract
PURPOSE Preference-based quality of life measures (PBMs) are used to generate quality-adjusted life years (QALYs) in economic evaluations. A PBM consists of (1) a health state classification system and (2) a utility value set that allows the instrument responses to be converted to QALYs. A new, oral health-specific classification system, the Early Childhood Oral Health Impact Scale-4D (ECOHIS-4D) has recently been developed. The aim of this study was to generate an Australian utility value set for the ECOHIS-4D. METHODS A discrete choice experiment with duration (DCETTO) was used as the preference elicitation technique. An online survey was administered to a representative sample of Australian adults over 18 years. Respondents were given 14 choice tasks (10 tasks from the DCE design of 50 choice sets blocked into five blocks, 2 practice tasks, a repeated and a dominant task). Data were analyzed using the conditional logit model. RESULTS A total of 1201 respondents from the Australian general population completed the survey. Of them, 69% (n = 829) perceived their oral health status to be good, very good, or excellent. The estimated coefficients from the conditional logit models were in the expected directions and were statistically significant (p < 0.001). The utility values for health states defined by the ECOHIS-4D ranged from 0.0376 to 1.0000. CONCLUSIONS This newly developed utility value set will enable the calculation of utility values for economic evaluations of interventions related to oral diseases such as dental caries among young children. This will facilitate more effective resource allocation for oral health services.

Cost-effectiveness of left atrial appendage closure for stroke prevention in atrial fibrillation: a systematic review appraising the methodological quality. COST EFFECTIVENESS AND RESOURCE ALLOCATION 2023; 21:76. [PMID: 37872572 PMCID: PMC10591401 DOI: 10.1186/s12962-023-00486-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Accepted: 10/10/2023] [Indexed: 10/25/2023] Open
Abstract
BACKGROUND The increasing global prevalence of atrial fibrillation (AF) has led to a growing demand for stroke prevention strategies, resulting in higher healthcare costs. High-quality economic evaluations of stroke prevention strategies can play a crucial role in maximising efficient allocation of resources. In this systematic review, we assessed the methodological quality of such economic evaluations. METHODS We searched electronic databases of PubMed, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, and Econ Lit to identify model-based economic evaluations comparing the left atrial appendage closure procedure (LAAC) and oral anticoagulants published in English since 2000. Data on study characteristics, model-based details, and analyses were collected. The methodological quality was evaluated using the modified Economic Evaluations Bias (ECOBIAS) checklist. For each of the 22 biases listed in this checklist, studies were categorised into one of four groups: low risk, partial risk, high risk due to inadequate reporting, or high risk. To gauge the overall quality of each study, we computed a composite score by assigning + 2, 0, - 1 and - 2 to each risk category, respectively. RESULTS In our analysis of 12 studies, majority adopted a healthcare provider or payer perspective and employed Markov Models with the number of health states varying from 6 to 16. Cost-effectiveness results varied across studies. LAAC displayed a probability exceeding 50% of being the cost-effective option in six out of nine evaluations compared to warfarin, six out of eight evaluations when compared to dabigatran, in three out of five evaluations against apixaban, and in two out of three studies compared to rivaroxaban. The methodological quality scores for individual studies ranged from 10 to - 12 out of a possible 24. Most high-risk ratings were due to inadequate reporting, which was prevalent across various biases, including those related to data identification, baseline data, treatment effects, and data incorporation. Cost measurement omission bias and inefficient comparator bias were also common. CONCLUSIONS While most studies concluded LAAC to be the cost-effective strategy for stroke prevention in AF, shortcomings in methodological quality raise concerns about reliability and validity of results. Future evaluations, free of these shortcomings, can yield stronger policy evidence.

Abstract
Purpose: There is poor reporting of the cost of simulation and greater transparency is needed. The primary study aim was to conduct a financial analysis of the university/training institution costs associated with a 5-day simulation-based learning program for speech-language pathology students. The secondary aim was to consider the economic costs of the model.Method: Costs associated with the delivery of a 5-day simulation-based learning program for speech-language pathology students from six Australian universities were collected regarding: (a) pre-program training, (b) personnel, (c) room hire, (d) equipment, and (e) consumables. Both financial costs and economic costs (Australian dollar, at June 2017) were calculated per university site, and per student.Result: The simulation program was run 21 times involving 176 students. Average total financial cost per program ranged from $4717 to $11 425, with cost variation primarily attributed to local labour costs and various use of in-kind support. Average financial cost per student was $859 (range $683-$1087), however this was almost double ($1461 per student, range $857-$2019) in the economic cost calculation. Personnel was the largest contributing cost component accounting for 76.6% of financial costs. Personnel was also the highest contributing cost in the economic analysis, followed by room hire.Conclusion: This study provides clarity regarding financial and economic costing for a 5-day simulation-based learning program. These data can help universities consider potential up-front financial costs, and well as strategies for financial cost minimisation, when implementing simulation-based learning within the university context.

Valuing the Dental Caries Utility Index in Australia. Med Decis Making 2023; 43:901-913. [PMID: 37724663 PMCID: PMC10625724 DOI: 10.1177/0272989x231197149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Accepted: 07/06/2023] [Indexed: 09/21/2023]
Abstract
INTRODUCTION The Dental Caries Utility Index (DCUI) is a new oral health-specific health state classification system for adolescents, consisting of 5 domains: pain/discomfort, difficulty eating food/drinking, worried, ability to participate in activities, and appearance. Each domain has 4 response levels. This study aims to generate an Australian-specific utility algorithm for the DCUI. METHODS An online survey was conducted using a representative sample of the adult Australian general population. The discrete choice experiment (DCE) was used to elicit the preferences on 5 domains. Then, the latent utilities were anchored onto the full health-dead scale using the visual analogue scale (VAS). DCE data were modeled using conditional logit, and 2 anchoring procedures were considered: anchor based on the worst health state and a mapping approach. The optimal anchoring procedure was selected based on the model parsimony and the mean absolute error (MAE). RESULTS A total of 995 adults from the Australian general population completed the survey. The conditional logit estimates on 5 dimensions and levels were monotonic and statistically significant, except for the second level of the "worried" and "appearance" domains. The mapping approach was selected based on a smaller MAE between the 2 anchoring procedures. The Australian-specific tariff of DCUI ranges from 0.1681 to 1. CONCLUSION This study developed a utility algorithm for the DCUI. This value set will facilitate utility value calculations from the participants' responses for DCUI in economic evaluations of dental caries interventions targeted for adolescents. HIGHLIGHTS Preference-based quality-of-life measures (PBMs), which consist of a health state classification system and a set of utility values (a scoring algorithm), are used to generate utility weights for economic evaluations.This study is the first to develop an Australian utility value set for the Dental Caries Utility Index (DCUI), a new oral health-specific classification system for adolescents.The availability of a utility value set will enable using DCUI in economic evaluations of oral health interventions targeted for adolescents and may ultimately lead to more effective and efficient planning of oral health care services.

Preferences in the Design and Delivery of Neurodevelopmental Follow-Up Care for Children: A Systematic Review of Discrete Choice Experiments. Patient Prefer Adherence 2023; 17:2325-2341. [PMID: 37745632 PMCID: PMC10517687 DOI: 10.2147/ppa.s425578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 08/31/2023] [Indexed: 09/26/2023] Open
Abstract
Neurodevelopmental disorders are a significant cause of morbidity. Early detection of neurodevelopmental delay is essential for timely diagnosis and intervention, and it is therefore important to understand the preferences of parents and clinicians for engaging with neurodevelopmental surveillance and follow-up care. Discrete choice experiment (DCE) may be an appropriate method for quantifying these preferences. This review systematically examined how DCEs have been designed and delivered in studies examining neurodevelopmental care of children and identified the preferred attributes that have been reported. PubMed, Embase, CINAHL, and Scopus databases were systematically searched. Studies were included if they used DCE to elicit preferences for a neurodevelopmental follow-up program for children. Two independent reviewers conducted the title and abstract and full-text screening. Risk of bias was assessed using a DCE-specific checklist. Findings were presented using a narrative synthesis. A total of 6618 records were identified and 16 papers were included. Orthogonal (n=5) and efficient (n=5) experimental designs were common. There was inconsistent reporting of design-related features. Analysis was primarily completed using mixed logit (n=6) or multinomial logit (n=3) models. Several key attributes for neurodevelopmental follow-up care were identified including social, behavioral and emotional support, therapy, waiting time, and out-of-pocket costs. DCE has been successfully used as a preference elicitation method for neurodevelopmental-related care. There is scope for improvement in the design and analysis of DCE in this field. Nonetheless, attributes identified in these studies are likely to be important considerations in the design and implementation of programs for neurodevelopmental care.

A discrete choice experiment to elicit preferences for a liver screening programme in Queensland, Australia: a mixed methods study to select attributes and levels. BMC Health Serv Res 2023; 23:950. [PMID: 37670274 PMCID: PMC10481473 DOI: 10.1186/s12913-023-09934-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Accepted: 08/17/2023] [Indexed: 09/07/2023] Open
Abstract
BACKGROUND In Australia, the overall prevalence of liver disease is increasing. Maximising uptake of community screening programmes by understanding patient preferences is integral to developing consumer-centred care models for liver disease. Discrete choice experiments (DCEs) are widely used to elicit preferences for various healthcare services. Attribute development is a vital component of a well-designed DCE and should be described in sufficient detail for others to assess the validity of outcomes. Hence, this study aimed to create a list of potential attributes and levels which can be used in a DCE study to elicit preferences for chronic liver disease screening programmes. METHODS Key attributes were developed through a multi-stage, mixed methods design. Focus groups were held with consumers and health care providers on attributes of community screening programmes for liver disease. Stakeholders then prioritised attributes generated from the focus group in order of importance via an online prioritisation survey. The outcomes of the prioritisation exercise were then reviewed and refined by an expert panel to ensure clinically meaningful levels and relevance for a DCE survey. RESULTS Fifteen attributes were generated during the focus group sessions deemed necessary to design liver disease screening services. Outcomes of the prioritisation exercise and expert panel stages recognised five attributes, with three levels each, for inclusion in a DCE survey to elicit consumer preferences for community screening for liver disease. This study also highlights broader social issues such as the stigma around liver disease that require careful consideration by policy makers when designing or implementing a liver screening programme. CONCLUSIONS The attributes and levels identified will inform future DCE surveys to understand consumer preferences for community screening programmes for liver disease. In addition, the outcomes will help inform the implementation of the LOCATE-NAFLD programme in real-world practice, and could be relevant for other liver and non-liver related chronic disease screening programmes.

Global and regional burden of ischemic stroke associated with atrial fibrillation, 2009-2019. Prev Med 2023; 173:107584. [PMID: 37348767 DOI: 10.1016/j.ypmed.2023.107584] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Revised: 05/27/2023] [Accepted: 06/19/2023] [Indexed: 06/24/2023]
Abstract
The extent of the preventable burden of ischaemic stroke associated with atrial fibrillation (AF) remains uncertain to date. To address this knowledge gap, we utilised the comparative risk assessment methodology to estimate the burden of ischaemic stroke associated with AF at both global and regional levels. The population attributable fraction for ischaemic stroke and AF was obtained from published literature, while data on the prevalence, incidence, deaths, and disability-adjusted life years (DALY) associated with ischaemic stroke were sourced from the Global Burden of Disease study database. Our analysis revealed that in 2019, globally, there were an estimated 0.7 (95% uncertainty interval [UI] of 0.55 to 0.83) million incident cases, 6.9 (5.81 to 8.12) million prevalence cases, 0.3 0.25 to 0.34) million deaths and 5.7 (4.91 to 6.57) million DALY resulting from ischaemic stroke associated with AF. The age-standardised death and DALY rates declined between 2009 and 2019 in all regions to varying degrees. Conversely, the age-standardised incidence and prevalence rates reduced only in high-income countries, Central Europe, Eastern Europe and Central Asia and Latin America and Caribbean regions. It is likely that our findings under-estimated the true burden of ischaemic stroke associated with AF due to limitations such as the use of a fixed population attributable fraction and poor quality of data. Nevertheless, we believe that our estimates provide valuable insights and highlight the urgent need for optimised management of AF through the implementation of efficacious interventions. Such efforts can help reduce the occurrence of preventable ischaemic strokes.

Abstract
BACKGROUND Heart failure is a leading cause of mortality and morbidity worldwide, and Atrial fibrillation (AF) is among many modifiable risk factors for heart failure. No estimates are available on the magnitude of the burden of heart failure associated with AF, and this study estimated the global, regional, and national burdens associated with AF. METHODS We used the comparative risk assessment method to estimate the disease burden in terms of prevalence and years lived with disability (YLD). The population-attributable fraction for heart failure and AF was calculated from prevalence estimates of AF and the recalculated relative risks of heart failure associated with AF from a systematic review summarising the longitudinal association between AF and outcomes. The burden of heart failure was retrieved from the Global Burden of Disease database. RESULTS Globally, 2.6% (95% uncertainty interval 1.3 to 4.7%) of the burden of heart failure is associated with AF. This was 1.5 (95% UI 0.6 to 3.2) million people in 2019, a 49.8% increase from 1990. The highest prevalence was from South-East Asia, East Asia and Oceania. The highest YLD was estimated for Central Europe, Eastern Europe and Central Asia. High-income countries showed a sharp decline in the age standardised prevalence and YLD rates from 1990 to 2019. CONCLUSION The burden of heart failure associated with AF has increased substantially over the past two decades despite the advances in AF management. However, falling prevalence and YLD rates of heart failure associated with AF in high-income countries over time indicate that reducing this burden is possible.

Cancer Survivor Preferences for Models of Breast Cancer Follow-Up Care: Selecting Attributes for Inclusion in a Discrete Choice Experiment. THE PATIENT 2023:10.1007/s40271-023-00631-0. [PMID: 37213062 DOI: 10.1007/s40271-023-00631-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Accepted: 04/13/2023] [Indexed: 05/23/2023]
Abstract
BACKGROUND AND OBJECTIVE It is critical to evaluate cancer survivors' preferences when developing follow-up care models to better address the needs of cancer survivors. This study was conducted to understand the key attributes of breast cancer follow-up care for use in a future discrete choice experiment (DCE) survey. METHODS Key attributes of breast cancer follow-up care models were generated using a multi-stage, mixed-methods approach. Focus group discussions were conducted with cancer survivors and clinicians to generate a range of attributes of current and ideal follow-up care. These attributes were then prioritised using an online survey with survivors and healthcare providers. The DCE attributes and levels were finalised via an expert panel discussion based on the outcomes of the previous stages. RESULTS Four focus groups were held, two with breast cancer survivors (n = 7) and two with clinicians (n = 8). Focus groups generated sixteen attributes deemed important for breast cancer follow-up care models. The prioritisation exercise was conducted with 20 participants (14 breast cancer survivors and 6 clinicians). Finally, the expert panel selected five attributes for a future DCE survey tool to elicit cancer survivors' preferences on breast cancer follow-up care. The final attributes included: the care team, allied health and supportive care, survivorship care planning, travel for appointments, and out-of-pocket costs. CONCLUSIONS Attributes identified can be used in future DCE studies to elicit cancer survivors' preferences for breast cancer follow-up care. This strengthens the design and implementation of follow-up care programs that best suit the needs and expectations of breast cancer survivors.

Hybrid cardiac telerehabilitation for coronary artery disease in Australia: a cost-effectiveness analysis. BMC Health Serv Res 2023; 23:512. [PMID: 37208666 PMCID: PMC10198753 DOI: 10.1186/s12913-023-09546-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Accepted: 05/14/2023] [Indexed: 05/21/2023] Open
Abstract
BACKGROUND Traditional cardiac rehabilitation programs are centre-based and clinically supervised, with their safety and effectiveness well established. Notwithstanding the established benefits, cardiac rehabilitation remains underutilised. A possible alternative would be a hybrid approach where both centre-based and tele-based methods are combined to deliver cardiac rehabilitation to eligible patients. The objective of this study was to determine the long-term cost-effectiveness of a hybrid cardiac telerehabilitation and if it should be recommended to be implemented in the Australian context. METHODS Following a comprehensive literature search, we chose the Telerehab III trial intervention that investigated the effectiveness of a long-term hybrid cardiac telerehabilitation program. We developed a decision analytic model to estimate the cost-effectiveness of the Telerehab III trial using a Markov process. The model included stable cardiac disease and hospitalisation health states and simulations were run using one-month cycles over a five-year time horizon. The threshold for cost-effectiveness was set at $AU 28,000 per quality-adjusted life-year (QALY). For the base analysis, we assumed that 80% completed the programme. We tested the robustness of the results using probabilistic sensitivity and scenario analyses. RESULTS Telerehab III intervention was more effective but more costly and was not cost-effective, at a threshold of $28,000 per QALY. For every 1,000 patients who undergo cardiac rehabilitation, employing the telerehabilitation intervention would cost $650,000 more, and 5.7 QALYs would be gained, over five years, compared to current practice. Under probabilistic sensitivity analysis, the intervention was cost-effective in only 18% of simulations. Similarly, if the intervention compliance was increased to 90%, it was still unlikely to be cost-effective. CONCLUSION Hybrid cardiac telerehabilitation is highly unlikely to be cost-effective compared to the current practice in Australia. Exploration of alternative models of delivering cardiac telerehabilitation is still required. The results presented in this study are useful for policymakers wanting to make informed decisions about investment in hybrid cardiac telerehabilitation programs.

Evaluating the costs and consequences of computerized clinical decision support systems in hospitals: a scoping review and recommendations for future practice. J Am Med Inform Assoc 2023; 30:1205-1218.

Abstract
OBJECTIVE Sustainable investment in computerized decision support systems (CDSS) requires robust evaluation of their economic impacts compared with current clinical workflows. We reviewed current approaches used to evaluate the costs and consequences of CDSS in hospital settings and presented recommendations to improve the generalizability of future evaluations. MATERIALS AND METHODS A scoping review of peer-reviewed research articles published since 2010. Searches were completed in the PubMed, Ovid Medline, Embase, and Scopus databases (last searched February 14, 2023). All studies reported the costs and consequences of a CDSS-based intervention compared with current hospital workflows. Findings were summarized using narrative synthesis. Individual studies were further appraised against the Consolidated Health Economic Evaluation and Reporting (CHEERS) 2022 checklist. RESULTS Twenty-nine studies published since 2010 were included. Studies evaluated CDSS for adverse event surveillance (5 studies), antimicrobial stewardship (4 studies), blood product management (8 studies), laboratory testing (7 studies), and medication safety (5 studies). All studies evaluated costs from a hospital perspective but varied based on the valuation of resources affected by CDSS implementation, and the measurement of consequences. We recommend future studies follow guidance from the CHEERS checklist; use study designs that adjust for confounders; consider both the costs of CDSS implementation and adherence; evaluate consequences that are directly or indirectly affected by CDSS-initiated behavior change; examine the impacts of uncertainty and differences in outcomes across patient subgroups. DISCUSSION AND CONCLUSION Improving consistency in the conduct and reporting of evaluations will enable detailed comparisons between promising initiatives, and their subsequent uptake by decision-makers.

Cost-Effectiveness of Screening to Identify Patients With Atrial Fibrillation: A Systematic Review. Heart Lung Circ 2023:S1443-9506(23)00152-X. [PMID: 37100697 DOI: 10.1016/j.hlc.2023.03.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 03/26/2023] [Accepted: 03/29/2023] [Indexed: 04/28/2023]
Abstract
BACKGROUND Screening for Atrial Fibrillation (AF) is recommended for people aged above 65 years. Screening for AF in asymptomatic individuals can be beneficial by enabling earlier diagnosis and the commencement of interventions to reduce the risk of early events, thus improving patient outcomes. This study systematically reviews the literature about the cost-effectiveness of various screening methods for previously undiagnosed AF. METHODS Four databases were searched to identify articles that are cost-effectiveness studies conducted on screening for AF published from January 2000 to August 2022. The Consolidated Health Economic Evaluation Reporting Standards 2022 checklist was used to assess the quality of the selected studies. A previously published approach was used to assess the usefulness of each study for health policy makers. RESULTS The database search yielded 799 results, with 26 articles meeting the inclusion criteria. Articles were categorised into four subgroups: (i) population screening, (ii) opportunistic screening, (iii) targeted, and (iv) mixed methods of screening. Most of the studies screened adults ≥65 years of age. Most studies were performed from a 'health care payer perspective' and almost all studies used 'not screening' as a comparator. Almost all screening methods assessed were found to be cost-effective in comparison to 'not screening'. The reporting quality varied between 58% to 89%. The majority of the studies were found to be of limited usefulness for health policy makers, as none of the studies made any clear statements about policy change or implementation direction. CONCLUSION All approaches of AF screening were found to be cost-effective compared with no screening, while opportunistic screening was found to be the optimal approach in some studies. However, screening for AF in asymptomatic individuals is context specific and likely to be cost-effective depending on the population screened, screening approach, frequency, and the duration of screening.

Abstract
BACKGROUND Teeth affected with enamel defects (EDs) are at an increased risk of dental caries. In spite of improving oral health status overall in Australia, Indigenous Australians still experience higher rates of dental caries than non-Indigenous Australians. This study reports on the prevalence of EDs and dental caries experience among Indigenous children in the Kimberley region of Western Australia. METHODS Health status of all the primary teeth (ICDAS II criteria) and the presence of EDs on index teeth (modified Dental Defects of Enamel index; DDE) of young Indigenous children who participated in a 2-arm intervention trial was recorded. Generalized estimating equations were used to estimate the association between EDs and dental caries and effect estimates were presented as odds ratios and associated 95% confidence intervals. RESULTS Person-level prevalence, from 237 children (mean age 3.6 years, standard deviation 1.7) assessed for EDs, was 58% and tooth-level prevalence was 24%. Teeth affected with demarcated or diffuse defects were associated with a twofold higher odds of having caries experience, odds ratio (OR) 2.5, 95% confidence interval (CI) 1.7-3.7 and OR 2.7, 95% CI 1.7-4.0 respectively. CONCLUSIONS The presence of EDs among young Indigenous children was associated with a higher odds of caries experience among affected teeth.

Abstract
OBJECTIVES The management of early childhood caries is challenging and the impacts of its treatment on child oral health-related quality of life (COHRQoL) and dental anxiety among Australian Aboriginal children is relatively unknown. The aim of the study was to compare the impact on COHRQoL and dental anxiety after approximately 12 months among Aboriginal children treated for early childhood caries (ECC) using the Atraumatic Restorative Treatment and the Hall Technique (ART/HT: test) or standard care (control). METHODS Consenting Aboriginal communities in the North-West of Western Australia were randomized into early (test) or delayed (control) intervention for the management of ECC. Children and parents/carers completed a questionnaire at baseline and at follow-up. The questionnaire sought information on COHRQoL using the proxy-reported Early Childhood Oral Health Impact Scale (ECOHIS) and the self-reported Caries Impacts and Experiences Questionnaire for Children (CARIES-QC). The test group was provided with the ART/HT care at baseline while the control group was advised to seek care through the usual care options available within the community. At follow-up, both groups were offered care using the ART/HT approach. Changes in the mean scores from baseline to follow-up within groups were evaluated using appropriate paired (t-test, Wilcoxon paired test), and between groups with unpaired tests (t-test). Multivariate regression analysis after multiple imputations of missing data used generalized estimating equation (GEE) controlling for clustering within communities. RESULTS Twenty-five communities and 338 children (mean age = 3.6 years, sd 1.7) participated in the study (test = 177). One child was excluded from the analysis because of a missing questionnaire and clinical data at baseline and follow-up. At baseline, test group children were older (test = 3.8 years, 95% CI 3.6-4.1;control = 3.3 years, 95% CI 3.1-3.6) and had higher caries experience (test dmft = 4.4, 95% CI 3.8-5.0;control dmft = 3.1, 95% CI 2.5-3.7), but there was no significant difference in COHRQoL or anxiety levels between the groups. At follow-up, parents in the delayed intervention reported worsening of COHRQoL (70% worsening of the family impact section of the ECOHIS and 37% worsening of the total ECOHIS scale), and there was an 8% reduction in child dental anxiety among the early treatment group. CONCLUSIONS The application of the ART/HT approaches was feasible, effective, and impacted positively on child oral health-related quality of life and child dental anxiety among Aboriginal children in remote communities. The model of care as tested in this study should be further developed for inclusion in main-stream service delivery programmes.

Abstract
The provision of effective care models for children with neurodevelopmental delay or disability can be challenging in resource constrained healthcare systems. Economic evaluations have an important role in informing resource allocation decisions. This review systematically examined the scope and methods of economic models evaluating interventions for supporting neurodevelopment among children with common neurodevelopmental disorders and identified methods of economic models and presented policy implications. This scoping review employed the Arksey and O'Malley framework and aligned with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Four electronic databases were systematically searched to identify eligible model-based economic evaluations of neurodevelopmental care models published since 2000. The Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist was used to assess quality of reporting. Data were systematically extracted, tabulated, and qualitatively synthesised across diagnostic categories. Searches identified 1431 unique articles. Twelve studies used a decision analytic model to evaluate care for neurodevelopmental disorders and were included in the review. Included studies focused on attention-deficit/hyperactivity disorder (ADHD, n=6), autism spectrum disorder (ASD, n=3), cerebral palsy (n=2), and dyslexia (n=1). The most used decision analytic modelling approach was a Markov model (n=6), followed by a decision tree (n=3), and a combination of decision tree and Markov model (n=3). Most studies (n=7) adopted a societal perspective for reporting costs. None of the reviewed studies modelled impact on families and caregivers. Four studies reported cost-savings, three identified greater quality of life, and three identified cost increases.

Abstract
INTRODUCTION There is a severe shortage of donor organs globally. There is growing interest in understanding how a 'soft opt-out' organ donation system could help bridge the supply and demand gap for donor organs. This research aims to estimate the cost-effectiveness and budget impact of implementing a 'soft opt-out' organ donation system for kidney donation. METHODS A decision-analytic model was developed to estimate the incremental costs from a health system's perspective, quality-adjusted life-years (QALYs), and death averted of people who have kidney failure, comparing a 'soft opt-out' organ donation system to an 'opt-in' system. This study analysed three scenarios where the 'soft opt-out' system generated a 20%, 30%, and 40% increase in deceased organ donation rates over 20 years. A 5-year time horizon was adopted for the budget impact analysis. RESULTS A 20% increase in organ donation rates could have a cost saving of 650 million Australian dollars (A$) and a 10,400-QALY gain. A 20% increase would avert more than 1500 deaths, while a 40% increase would avert 3200 deaths over a time horizon of 20 years. Over the first 5 years, a 20% increase would have a net saving of A$53 million, increasing to A$106 million if the donation rate increases by 40%. CONCLUSION A 'soft opt-out' organ donation system would return a cost saving for the healthcare system, a net gain in QALYs, and prevention of a significant number of deaths. Advantageous budgetary impact is important, but understanding the aversion for a 'soft opt-out' system in Australia is also important and remains a priority for further research.

A Bayesian Approach for Incorporating the EQ-5D Visual Analog Scale When Estimating the Health-Related Quality of Life. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2022; 25:1575-1581. [PMID: 35304036 DOI: 10.1016/j.jval.2022.01.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Revised: 11/10/2021] [Accepted: 01/21/2022] [Indexed: 06/14/2023]
Abstract
OBJECTIVES The EuroQoL 3-level version of EQ-5D and 5-level version of EQ-5D questionnaires are often used to quantify health states. They include ordinal responses across 5 health dimensions (EQ-5D index) and an EQ-visual analog scale (EQ-VAS) overall health rating. We investigated the value of incorporating the EQ-VAS to update health utility estimates using a Bayesian framework. METHODS We created a joint bivariate normal EQ-VAS and EQ-5D index utility model and compared this to a univariate normal EQ-5D index utility model. We tested these models for 1026 Sri Lankan patients with chronic kidney disease and 94 Australian patients with wounds. We validated our approach by simulating EQ-VAS and EQ-5D index responses and applying our Bayesian model and then comparing the modeled estimates to our observed data. RESULTS The combined model showed a reduction in estimate uncertainty for all respondents. Compared with the EQ-5D index-only model, the mean utility for Sri Lankan respondents dropped from 0.556 (0.534-0.579) to 0.540 (0.521-0.559) in men and increased from 0.489 (0.461-0.518) to 0.528 (0.506-0.550) in women, with reduced credible interval width by 13% and 23%, respectively. The mean utility in Australian respondents moved from 0.715 (0.633-0.800) to 0.716 (0.652-0.782) in men, and 0.652 (0.581-0.723) to 0.652 (0.593-0.711) in women, with reduced credible interval width by 23% and 17%, respectively. The credible interval width for simulated data also narrowed, ranging from 8.3 to 8.5%. CONCLUSIONS Including the EQ-VAS through Bayesian methods can add value by reducing requisite sample sizes and decision uncertainty using small amounts of additional data that is often collected but rarely used.

Presentation, Diagnosis and Treatment Delays in Breast Cancer Care and Their Associations in Sri Lanka, a Low-resourced Country. Clin Oncol (R Coll Radiol) 2022; 34:598-607. [PMID: 35672184 DOI: 10.1016/j.clon.2022.05.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 04/08/2022] [Accepted: 05/11/2022] [Indexed: 11/03/2022]
Abstract
AIMS Delays in breast cancer care, one important attributable factor for breast cancer being diagnosed at advanced stages, are not systematically studied in many countries. This study assessed the magnitude and factors associated with delays in breast cancer care in Sri Lanka, from symptom detection to treatment initiation. MATERIALS AND METHODS We interviewed 800 consecutively sampled female breast cancer patients, diagnosed within the last 12 months, using context-specific questionnaires and medical records. We defined the cut-off times for delays using international guidelines and features of the national health system and care-seeking patterns in the country. Delays were estimated as proportions with 95% confidence intervals and presented for: (i) presentation delay; (ii) diagnosis delay and (iii) treatment delay. We looked at how sociodemographic and healthcare availability and accessibility at the individual level were associated with delays using multivariate logistic regression, with a P value of 0.05 to define statistical significance. RESULTS Nearly two-thirds of patients reported a presentation delay (63.3%, 95% confidence interval 59.9-66.6%). A diagnosis delay (36.7%, 95% confidence interval 33.4-40.0%) was also seen among one-third, whereas treatment delays (13.2%, 95% confidence interval 10.8-15.5%) were less common. Low family monthly income (odds ratio 6.3; 95% confidence interval 4.2-9.3) and poor knowledge on breast cancer (odds ratio 2.7; 95% confidence interval 1.8-3.8) were associated with presentation delay. Poor health literacy (odds ratio 1.7; 95% confidence interval 1.1-2.7) and the need to make more than two visits to the first contact health provider prior to diagnosis (odds ratio 7.2; 95% confidence interval 4.6-11.1) were associated with diagnosis delays, whereas directly contacting an appropriate specialised health provider once the lump was detected reduced diagnosis delay (odds ratio 0.3; 95% confidence interval 0.2-0.4). Having undergone a core biopsy (odds ratio 0.5; 95% confidence interval 0.3-0.8) and having a mammogram (odds ratio 0.6; 95% confidence interval 4.7-32.7) reduced the likelihood of treatment delays. CONCLUSIONS Our study findings show that delays in breast cancer care in Sri Lanka are much lower than those in other lower-middle income countries. However, there is significant room for improvement, especially in relation to the excellence in quality of care, such as improving access to mammography services. Periodical estimation of breast cancer delays enabling temporal comparisons will probably provide useful information to policy makers in improving care delivery for breast cancer patients and, hence, is recommended. Such future assessments designed for comparisons between different treatment modalities would provide more information to assist policy decisions in care improvement.

Economic burden of patients living with heart disease in the last years of life in Australia: a retrospective analysis using linked data. EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2022; 8:333-341. [PMID: 33724356 DOI: 10.1093/ehjqcco/qcab006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Revised: 01/04/2021] [Accepted: 02/03/2021] [Indexed: 06/12/2023]
Abstract
AIMS People living with heart disease are at elevated risk of hospitalization during the last years of their life. The aim of this study was to describe hospitalization-related usage patterns, and associated cost burden, for patients living with heart disease in the last 6 years of their life. METHODS AND RESULTS The study was an observational cohort study, using routinely collected and linked data from hospital admission (HA), emergency department (ED) presentation and death registry data in Queensland, Australia. The study sample included 1000 randomly selected patients who died in 2017 due to any cause who had been living with heart disease for at least the prior 6 years. The two main outcomes of interest in this study were cost of HAs and cost of ED presentation in the last 6 years before death. Total cost was calculated as a sum of direct and overhead costs from each of the hospital presentations. The mean HA per patient in the sixth year, second year, and last year prior to death was 5.3, 6.6, and 7.5, respectively, with a similar pattern observed for ED presentations. The associated costs per patient from HA followed a similar trajectory increasing gradually from $17 711 in the sixth year to $26 658 in the second last year prior to death. A similar pattern was observed for ED presentation costs. CONCLUSION The large increase cost in the last year of life was primarily attributable to higher treatment cost per HA at end of life.

Cost-effectiveness analysis of paediatric mental health interventions: a systematic review of model-based economic evaluations. BMC Health Serv Res 2022; 22:542. [PMID: 35459236 PMCID: PMC9034631 DOI: 10.1186/s12913-022-07939-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Accepted: 03/30/2022] [Indexed: 11/22/2022] Open
Abstract
Mental health disorders among children and youth are causing significant burden on health care systems. Hence, identifying cost-effective interventions is important for effective mental health care allocation. Although model-based economic evaluations are an essential component of assessing cost-effectiveness, evidence are limited in the context of child and youth mental health care. The objective was to systematically review the model-based economic evaluations of mental health interventions for children and youth. Methods Four databases (MEDLINE, EMBASE, PsycINFO and Web of Science) were searched using appropriate search terms to retrieve model-based economic evaluations of mental health interventions for children and youth. The reporting quality of the included studies were appraised using the Consolidated health economic evaluation reporting standards (CHEERS) checklist. Results The database search yielded 1921 records. Of the 12 selected for review, 66% were published after year 2015. Most of the studies were related to anxiety and post-traumatic stress disorder. There were eight cost-utility studies, three cost-effectiveness studies, and one study using both forms of analysis. Six studies used Markov models, three used decision trees, and three studies used both types of models. However, the model structure, health states, time horizon, and economic perspective showed wide variation. The reporting quality of the included studies varied from 91 to 96%. Conclusion Model based mental health economic evaluations among children and youth are increasingly being reported in recent research. The included studies used Markov models and decision trees, either alone or in combination, and the majority of the articles were of good reporting quality.

Financial Costs of Emergency Department Presentations for Australian Patients With Heart Disease in the Last 3 Years of Life. Health Serv Insights 2022; 15:11786329221091038. [PMID: 35431555 PMCID: PMC9008821 DOI: 10.1177/11786329221091038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Accepted: 03/11/2022] [Indexed: 11/17/2022] Open
Abstract
Aims: This study described emergency department (ED) resource use patterns and associated costs among patients with heart disease in their last 3 years of life in a high-income country. Methods: This study used linked data from ED and death registry databases in Australia. A random sample of 1000 patients who died due to any cause in 2017, and who had been living with heart disease for at least the prior 10-years were included. The outcomes of interest were number of ED presentations over each of the last 3 years prior to death and relative cost contributions of ED-related items. Results: The number of patients needing ED care and number of ED presentations per patient increased as patients were closer to death, with 85% experiencing at least one ED presentation in their last year of life. Mean per patient ED presentation cost increased with each year closer to death. Costs related to labor, pathology, patient travel, and goods and services contributed more than 85% of the total cost in each of the 3 years. Conclusion: The increase in cost burden as patients neared death was attributable to more frequent ED presentations per person rather than more expensive ED presentations. The scope of this study was limited to ED presentations, and may not be representative of heart-disease-related end-of-life care more broadly.

Development of a classification (descriptive) system for a preference-based quality of life measure for dental caries (dental caries utility index) among adolescents. J Public Health Dent 2021; 82:253-261. [PMID: 34859442 DOI: 10.1111/jphd.12490] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 10/16/2021] [Accepted: 11/15/2021] [Indexed: 11/27/2022]
Abstract
OBJECTIVES Preference-based quality-of-life measures (PBMs) have been developed in many clinical areas to aid estimation of more accurate utility values for economic evaluations. Existing oral health-related quality-of-life (OHRQoL) instruments are non-PBM and hence, cannot be used to generate utility values. The objective of this study was to develop a classification system for a new PBM (dental caries utility index-DCUI) for the most prevalent childhood oral health condition: dental caries. METHODS Possible domains and items to be included in the classification system were identified based on the reviewing available pediatric non-PBM OHRQoL instruments, studies eliciting utility values for oral health outcomes and clinical dentistry textbooks and based on the findings, a draft classification system was developed. To refine the draft classification system, semi-structured interviews were conducted among a convenience sample of 15 12-17-year-old adolescents who had experience with dental caries. The classification system was further refined and validated by a group of dental experts, using a modified Delphi technique. RESULTS The classification system comprised five items (pain/discomfort, difficulty in eating food/drinking, worried, ability to participate in activities, and appearance) and each item had a four-level response scale. CONCLUSION The classification system developed herein is considered an amenable tool for the subsequent development of a new PBM for dental caries. Once the scoring algorithm is completed, the classification system can be used to incorporate economic evaluations of dental caries health interventions.

Abstract
INTRODUCTION The HealthPathways programme is an online health information system used mainly in primary health care to promote a consistent and integrated approach to patient care. AIM The aim of this study is to perform a scoping review of the methodologies used in published impact and outcomes evaluations of HealthPathways programmes. METHODS The review included qualitative, quantitative or mixed-methods evaluations of the impact or outcome of HealthPathways. MEDLINE, Embase, CINAHL and Web of Science databases were searched. Seven programme aims were identified in the impact and outcome evaluation: (1) increased awareness and use of HealthPathways; (2) general practitioners are supported to adopt best practice, patient-centred care; (3) increased appropriate use of resources and services; (4) improved quality of referrals; (5) enhanced consistent care and management of health conditions; (6) improved patient journeys through the local health system; and (7) reduction in health-care cost and increased value for money. RESULTS Twenty-one studies were included in the final review; 15 were research papers and six were reports. 'Increased awareness and use of HealthPathways' was the most frequent programme aim evaluated (n = 12). Quantitative and qualitative research methodologies, as well as prospective and retrospective data collections, have been adopted to evaluate the impact and outcome of HealthPathways. DISCUSSION Assessing the impacts and outcomes of HealthPathways may be challenging due to limitations in primary data and the interconnectedness of change across the measured aims. Each aim may therefore require specific methodologies sensitive enough to capture the impact that HealthPathways are making over time.

Abstract
INTRODUCTION HealthPathways is a clinical information portal developed in New Zealand that enables general practitioners to manage and refer their patients in a local context. We analyzed specialist outpatient appointment costs in Mackay, Queensland before and after HealthPathways implementation. METHODS We retrospectively examined specialist outpatient costs for patients referred by Mackay general practitioners for conditions with varying levels of HealthPathways implementation. Ranked from most clinical pathways available to none, chronic diabetes, cardiology, respiratory, and urology visits from January to March 2015, pre-pathways, and January to March 2017, post-pathways, were assessed. Monte Carlo simulation was used to estimate cost changes. Per-visit costs were multiplied by visit numbers to estimate policy impact. RESULTS The mean cost per visit increased from $220 to $305 for diabetes and $270 to $323 for respiratory, and decreased from $296 to $257 for cardiology and $444 to $293 for urology. The policy impact for each disease group over 3 months after accounting for visit numbers was a likely saving of $30 360 for diabetes and $10 270 for cardiology, and a likely cost increase of $24 449 for respiratory and $20 536 for urology. CONCLUSIONS We observed that conditions with more comprehensive clinical pathways cost Mackay HHS substantially less following implementation. Costs for low and no pathway implementation referrals increased slightly over the same period.

Abstract
Background Kidney graft failure risk prediction models assist evidence-based medical decision-making in clinical practice. Our objective was to develop and validate statistical and machine learning predictive models to predict death-censored graft failure following deceased donor kidney transplant, using time-to-event (survival) data in a large national dataset from Australia. Methods Data included donor and recipient characteristics (n = 98) of 7,365 deceased donor transplants from January 1st, 2007 to December 31st, 2017 conducted in Australia. Seven variable selection methods were used to identify the most important independent variables included in the model. Predictive models were developed using: survival tree, random survival forest, survival support vector machine and Cox proportional regression. The models were trained using 70% of the data and validated using the rest of the data (30%). The model with best discriminatory power, assessed using concordance index (C-index) was chosen as the best model. Results Two models, developed using cox regression and random survival forest, had the highest C-index (0.67) in discriminating death-censored graft failure. The best fitting Cox model used seven independent variables and showed moderate level of prediction accuracy (calibration). Conclusion This index displays sufficient robustness to be used in pre-transplant decision making and may perform better than currently available tools.

Abstract
Background Oral Health Related Quality of Life (OHRQoL) measures have emerged as an important oral health outcome that is able to reveal the subjective burden of illness due to oral diseases. The association between sociodemographic and socioeconomic factors, clinical dental conditions and OHRQoL indicators has been investigated in adolescent populations across the world. The purpose of this study was to investigate key factors associated with oral health-related quality of life of Sri Lankan adolescents. Methods A cross sectional study was conducted in a sample of 15–19 year-old secondary school students in the Gampaha district of Sri Lanka. The data was collected using two self-administered questionnaires. A modified Sinhalese version of the Oral Impact on Daily Performance (OIDP) questionnaire that has been validated for Sri Lankan adolescents was administered. A second questionnaire collected information on socioeconomic characteristics, oral health care seeking and oral health behaviours. A clinical oral examination was performed on each participant. Oral health related quality of life was measured using OIDP domains and total OIDP scores. Poisson regression was used to investigate the key factors associated with the OIDP additive score. Results A total of 1332 adolescents participated in the study. Negative quality of life impacts were more prevalent in the social and psychological domains of OIDP as compared with the functional domain. Total OIDP scores ranged from 0 to 36 with a mean of 3.16 (SD = 4.71). The multivariable analysis revealed that increasing age, low income, brushing teeth only once per day, and increased number of decayed teeth were found to be associated with poor overall OHRQoL, while male gender, frequent oral healthcare seeking patterns and absent dento-facial anomalies were associated with good OHRQoL. Conclusion This study identified modifiable behavioural and oral health related factors which are associated with OHRQoL in Sri Lankan adolescents. Oral health interventions should target these modifiable factors to improve the OHRQoL in these populations.

Abstract
OBJECTIVES Cancer of the oral cavity is the leading malignancy amongst males in Sri Lanka, and eighth amongst women. Almost all malignancies are developed from a clinically visible precursor stage called an oral potentially malignant disorder (OPMD). The objective of this study was to estimate costs of managing patients with OPMD in Sri Lanka for a 12-month period from diagnosis. METHODS A hospital-based costing study was conducted in Sri Lanka in the years 2016-2017. Three selected treatment centres participated. For societal perspectives, healthcare, household and indirect costs were used. Costs to the healthcare system included clinic visits, diagnostic biopsy, consumables and drug costs. Capital costs included apportioned value of land, buildings, equipment and furniture. Household costs consisted of out-of-pocket expenditure and indirect costs of lost income. RESULTS Sixty-two patients were recruited (39 male and 23 female). The majority had awareness of oral potentially malignant disorders (OPMDs). Total average cost of managing a single patient with an OPMD for 1 year was SLR 19 547 (US$ 140) which includes a health system cost of SLR 7320 (US$ 52) and household cost of SLR 12 227 (US$ 87). Travel loss and income loss were a substantial burden to patients and their families. CONCLUSIONS Managing patients with an OPMD, even with annual monitoring, is less costly than managing patients with oral cancer. Out-of-pocket costs are very high, and these could be reduced by revising the National Management Guidelines to allow care closer to home.

Developing an early childhood oral health impact-specific health-state classification system for a new preference-based instrument, the ECOHIS-4D. Community Dent Oral Epidemiol 2021; 50:191-198. [PMID: 33870551 DOI: 10.1111/cdoe.12650] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Revised: 03/26/2021] [Accepted: 03/30/2021] [Indexed: 12/19/2022]
Abstract
OBJECTIVES Most of the paediatric quality-of-life instruments in oral health research are not preference-based measures, thus cannot be used in economic evaluations. The Early Childhood Oral Health Impact Scale (ECOHIS) is one such instrument which assesses oral health impact on children's quality of life among three- to five-year-olds. With increasing demands for more resource allocation in oral health care, there is a need for an outcome metric which can be used as the outcome in economic evaluations. The aim of this study was to develop a preference-based, health-state classification system from the existing ECOHIS instrument. METHODS The 13-item ECOHIS instrument was applied to the carers of 280 preschoolers who participated in a clinical trial in metropolitan Perth, Western Australia. Exploratory factor analysis was conducted to assess the dimensionality of the ECOHIS. Rasch analysis was used to eliminate and select items per determined dimensions and to reduce the number of response options for each item, because six levels were not amenable to valuation. The final classification system was determined through a combination of psychometric and expert advice. RESULTS Items loaded on to four dimensions with the factor analysis. Using Rasch analysis, three items were selected from the first dimension (child functional and psychological impact) and one item from the second dimension (child social interaction impact). None were selected from the third dimension (parental distress and family function impact) as it is not an appropriate proxy method of measuring the level of impact on a child. The final classification system has four dimensions with three levels in each, and so it has been named the ECOHIS-4D. CONCLUSIONS The ECOHIS-4D classification system is a new preference-based instrument derived from the existing ECOHIS instrument. Future valuation studies will develop a utility value set for the health states defined by this classification system, and this will guide economic evaluations related to oral health interventions.

Time-to-event analysis in economic evaluations: a comparison of modelling methods to assess the cost-effectiveness of transplanting a marginal quality kidney. HEALTH ECONOMICS REVIEW 2021; 11:13. [PMID: 33856573 PMCID: PMC8051030 DOI: 10.1186/s13561-021-00312-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/25/2020] [Accepted: 03/29/2021] [Indexed: 06/12/2023]
Abstract
BACKGROUND Economic-evaluations using decision analytic models such as Markov-models (MM), and discrete-event-simulations (DES) are high value adds in allocating resources. The choice of modelling method is critical because an inappropriate model yields results that could lead to flawed decision making. The aim of this study was to compare cost-effectiveness when MM and DES were used to model results of transplanting a lower-quality kidney versus remaining waitlisted for a kidney. METHODS Cost-effectiveness was assessed using MM and DES. We used parametric survival models to estimate the time-dependent transition probabilities of MM and distribution of time-to-event in DES. MMs were simulated in 12 and 6 monthly cycles, out to five and 20-year time horizon. RESULTS DES model output had a close fit to the actual data. Irrespective of the modelling method, the cycle length of MM or the time horizon, transplanting a low-quality kidney as compared to remaining waitlisted was the dominant strategy. However, there were discrepancies in costs, effectiveness and net monetary benefit (NMB) among different modelling methods. The incremental NMB of the MM in the 6-months cycle lengths was a closer fit to the incremental NMB of the DES. The gap in the fit of the two cycle lengths to DES output reduced as the time horizon increased. CONCLUSION Different modelling methods were unlikely to influence the decision to accept a lower quality kidney transplant or remain waitlisted on dialysis. Both models produced similar results when time-dependant transition probabilities are used, most notable with shorter cycle lengths and longer time-horizons.

Does the choice of care pathways matter in timely breast cancer care in Sri Lanka? Cancer Epidemiol 2020; 70:101862. [PMID: 33348244 DOI: 10.1016/j.canep.2020.101862] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Revised: 10/23/2020] [Accepted: 11/20/2020] [Indexed: 11/25/2022]
Abstract
BACKGROUND An understanding on the use of care pathways facilitates identification of timeliness in breast cancer care. Aims of this study were to describe different breast cancer care pathways used by female breast cancer patients in Sri Lanka and to identify whether they experienced timely breast cancer care. METHODS We conducted a cross-sectional study among 800 female breast cancer patients with a histological/ cytological confirmation, from four state cancer treatment centers. We conceptualized five different care pathways with essential care points and in-between time intervals to be explored using an interviewer administered tool. Dates were cross-checked with the medical record. The difference of time intervals spent in different care pathways was tested for significance using one-way ANOVA test. RESULTS Mean (SD) age was 55.5 (10.7) years. A vast majority of 98.4 % (n = 787) self-detected the breast lesion, while only 13 had been detected through screening. Following self-detection, two thirds (n = 473, 59.1 %, 95 % CI = 55.7-62.5) had first consulted a primary healthcare physician, and a third n = 287, 35.8 %, 95 % CI = 32.6-39.3) had consulted an appropriate specialist first. Presentation interval among those who visited an Ayurvedic physician first was significantly longer than other pathways (p < 0.0001). Diagnosis interval for those who consulted an appropriate consultant was significantly shorter than other pathways (p < 0.0001). CONCLUSIONS Women take up numerous care paths following self-detection of a breast lesion. Empowering women on appropriate care pathways and expanding dedicated breast clinics where women to be first seen by an appropriate specialist are likely to improve timely breast cancer care in Sri Lanka.

Donor Kidney Quality and Transplant Outcome: An Economic Evaluation of Contemporary Practice. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2020; 23:1561-1569. [PMID: 33248511 DOI: 10.1016/j.jval.2020.07.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Revised: 07/11/2020] [Accepted: 07/18/2020] [Indexed: 06/12/2023]
Abstract
OBJECTIVES The study had two main aims. First, we assessed the cost-effectiveness of transplanting deceased donor kidneys of differing quality levels based on the Kidney Donor Profile Index (KDPI). Second, we assessed the cost-effectiveness of remaining on the waiting list until a high-quality kidney becomes available compared to transplanting a lower-quality kidney. METHODS A decision analytic model to estimate cost-effectiveness was developed using a Markov process. Separate models were developed for 4 separate KDPI bands, with higher values indicating lower quality. Models were simulated in 1-year cycles for a 20-year time horizon, with transitions through distinct health states relevant to the kidney recipient from the healthcare payer's perspective. Weibull regression was used to calculate the time-dependent transition probabilities in the base analysis. The impact uncertainty arising in model parameters was included by probabilistic sensitivity analysis using the Monte Carlo simulation method. Willingness to pay was considered as Australian $28 000. RESULTS Transplanting a kidney of any quality is cost-effective compared to remaining on a waitlist. Transplanting a lower KDPI kidney is cost-effective compared to a higher KDPI kidney. Transplanting lower KDPI kidneys to younger patients and higher KDPI kidneys to older patients is also cost-effective. Depending on dialysis in hopes of receiving a lower KDPI kidney is not a cost-effective strategy for any age group. CONCLUSION Efforts should be made by the health systems to reduce the discard rates of low-quality kidneys with the view of increasing the transplant rates.

Abstract
INTRODUCTION A new health state classification system has been developed for dental caries - Dental Caries Utility Index (DCUI) to facilitate the assessment of oral health interventions in the cost-utility analysis (CUA). This paper reports the protocol for a valuation study, which aims to generate a preference-based algorithm for the classification system for the DCUI. METHODS AND ANALYSIS Discrete choice experiments (DCEs) will be conducted to value health states generated by the DCUI classification system and preferences for these health states will be modelled to develop a utility algorithm. DCEs produce utility values on a latent scale and these values will be anchored into the full health-dead scale to calculate the quality-adjusted life years in CUA. There is no previous evidence for the most suitable anchoring method for dental caries health state valuation. Hence, we will first conduct pilot studies with two anchoring approaches; DCE including duration attribute and DCE anchoring to worst heath state in Visual Analogue Scale. Based on the pilot studies, the most suitable anchoring method among two approaches will be used in the main valuation survey, which will be conducted as an online survey among a representative sample of 2000 adults from the Australian general population. Participants will be asked to complete a set of DCE choice tasks along with anchoring tasks, basic social-demographic questions, DCUI, a generic preference-based measure and oral health quality of life instrument. ETHICS AND DISSEMINATION Ethical approval for this study was obtained from the Human Research Ethics Committee, Griffith University (reference number HREC/2019/550). The generated algorithm will facilitate the use of the new dental caries preference-based measure in economic evaluations of oral health interventions. The results will be disseminated through journal articles and professional conferences.

Review of methods and study designs of evaluations related to clinical pathways. AUST HEALTH REV 2020; 43:448-456. [PMID: 30089529 DOI: 10.1071/ah17276] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2017] [Accepted: 05/19/2018] [Indexed: 11/23/2022]
Abstract
Objective The HealthPathways program is an online information portal that helps clinicians provide consistent and integrated patient care within a local health system through localised pathways for diagnosis, treatment and management of various health conditions. These pathways are consistent with the definition of clinical pathways. Evaluations of HealthPathways programs have thus far focused primarily on website utilisation and clinical users' experience and satisfaction, with limited evidence on changes to patient outcomes. This lack motivated a literature review of the effects of clinical pathways on patient and economic outcomes to inform a subsequent HealthPathways evaluation. Methods A systematic review was performed to summarise the analytical methods, study designs and results of studies evaluating clinical pathways with an economic outcome component published between 1 January 2000 and 31 August 2017 in four academic literature databases. Results Fifty-five relevant articles were identified for inclusion in this review. The practical pre-post study design with retrospective baseline data extraction and prospective intervention data collection was most commonly used in the evaluations identified. Straightforward statistical methods for comparing outcomes, such as the t-test or χ2 test, were frequently used. Only four of the 55 articles performed a cost-effectiveness analysis. Clinical pathways were generally associated with improved patient outcomes and positive economic outcomes in hospital settings. Conclusions Clinical pathways evaluations commonly use pragmatic study designs, straightforward statistical tests and cost-consequence analyses. More HealthPathways program evaluations focused on patient and economic outcomes, clinical pathway evaluations in a primary care setting and cost-effectiveness analyses of clinical pathways are needed. What is known about the topic? HealthPathways is a web-based program that originated from Canterbury, New Zealand, and has seen uptake elsewhere in New Zealand, Australia and the UK. The HealthPathways program aims to assist the provision of consistent and integrated health services through dedicated, localised pathways for various health conditions specific to the health region. Evaluations of HealthPathways program focused on patient and economic outcomes have been limited. What does this paper add? This review synthesises the academic literature of clinical pathways evaluations in order to inform a subsequent HealthPathways evaluation. The focus of the synthesis was on the analytical methods and study designs used in the previous evaluations. The previous clinical pathway evaluations have been pragmatic in nature with relatively straightforward study designs and analysis. What are the implications for practitioners? There is a need for more economic and patient outcome evaluations for HealthPathways programs. More sophisticated statistical analyses and economic evaluations could add value to these evaluations, where appropriate and taking into consideration the data limitations.

Deceased donor kidney allocation: an economic evaluation of contemporary longevity matching practices. BMC Health Serv Res 2020; 20:931. [PMID: 33036621 PMCID: PMC7547436 DOI: 10.1186/s12913-020-05736-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2020] [Accepted: 09/15/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Matching survival of a donor kidney with that of the recipient (longevity matching), is used in some kidney allocation systems to maximize graft-life years. It is not part of the allocation algorithm for Australia. Given the growing evidence of survival benefit due to longevity matching based allocation algorithms, development of a similar kidney allocation system for Australia is currently underway. The aim of this research is to estimate the impact that changes to costs and health outcomes arising from 'longevity matching' on the Australian healthcare system. METHODS A decision analytic model to estimate cost-effectiveness was developed using a Markov process. Four plausible competing allocation options were compared to the current kidney allocation practice. Models were simulated in one-year cycles for a 20-year time horizon, with transitions through distinct health states relevant to the kidney recipient. Willingness to pay was considered as AUD 28000. RESULTS Base case analysis indicated that allocating the worst 20% of Kidney Donor Risk Index (KDRI) donor kidneys to the worst 20% of estimated post-transplant survival (EPTS) recipients (option 2) and allocating the oldest 25% of donor kidneys to the oldest 25% of recipients are both cost saving and more effective compared to the current Australian allocation practice. Option 2, returned the lowest costs, greatest health benefits and largest gain to net monetary benefits (NMB). Allocating the best 20% of KDRI donor kidneys to the best 20% of EPTS recipients had the lowest expected incremental NMB. CONCLUSION Of the four longevity-based kidney allocation practices considered, transplanting the lowest quality kidneys to the worst kidney recipients (option 2), was estimated to return the best value for money for the Australian health system.

Abstract
INTRODUCTION The management of early childhood caries (ECC) is challenging. OBJECTIVES A model of care based on Atraumatic Restorative Treatment and the Hall Technique (ART-HT) to manage ECC was evaluated among remote Aboriginal communities in Australia. METHODS Aboriginal communities in the North-West of Western Australia were invited to participate and consenting communities were randomized into early or delayed intervention for the management of ECC. Children were examined at baseline and at the 11-mo follow-up. The early intervention group (test) was provided with the ART-based dental care at baseline while the delayed intervention group (control) was advised to seek care through the usual care options available within the community. At follow-up, both groups were examined by calibrated examiners, and were offered care using the ART-HT approach. Changes from baseline to follow-up in caries experience were tested using paired tests. Multivariate analysis after multiple imputation of missing data used generalised estimating equation (GEE) controlling for clustering within communities. RESULTS A total of 25 communities and 338 children (mean age = 3.6 y, SD 1.7) participated in the study (test = 177). At follow-up, 231 children were examined (68% retention, test = 125). At follow-up, children in the test group had more filled teeth (test filled teeth = 1.2, control filled teeth = 0.2, P < 0.001) and decreased levels of decayed teeth (mean test = 0.7 fewer teeth with decay, mean control = 1.0 more tooth with decay, P < 0.001). GEE analysis controlled for baseline caries experience, age, sex, and community water fluoride levels found increased rates of untreated decayed teeth (RR = 1.4, P = 0.02) and decreased rates of filled teeth (RR = 0.2, P < 0.001) at follow-up among the control group. CONCLUSION A model of care relying on the principles of minimally invasive atraumatic approaches enabled the delivery of effective dental services to young children (<6 y) in remote Aboriginal Australian communities resulting in increased levels of care and improved oral health. KNOWLEDGE TRANSFER STATEMENT This cluster-randomized trial tested a multi-component model of dental care to young children with ECC in remote Aboriginal communities in Australia. The intervention, based on the atraumatic approaches using minimally invasive techniques encompassing preventive care, Atraumatic Restorative Treatment and the Hall Technique (ART-HT), delivered more restorative care and reduced the incidence of caries. This model of care was more effective than available standard care and should be incorporated into mainstream service delivery programs.
