Prevalence of frailty and pain in hospitalised cancer patients: implications for older adult care. Intern Med J 2024; 54:671-674. [PMID: 38450876 DOI: 10.1111/imj.16351] [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: 11/29/2023] [Accepted: 01/24/2024] [Indexed: 03/08/2024]
Abstract
A hospital-wide point prevalence study investigated frailty and pain in patients with a cancer-related admission. Modifiable factors associated with frailty in people with cancer were determined through logistic regression. Forty-eight patients (19%) with cancer-related admissions were 2.65 times more likely to be frail and 2.12 more likely to have moderate pain. Frailty and pain were highly prevalent among cancer-related admissions, reinforcing the need for frailty screening and importance of pain assessment for patients with cancer.

Child and adolescent COVID-19 vaccination coverage by educational setting, United States. Public Health 2024; 229:126-134. [PMID: 38430658 PMCID: PMC10961195 DOI: 10.1016/j.puhe.2024.01.029] [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: 07/18/2023] [Revised: 01/20/2024] [Accepted: 01/27/2024] [Indexed: 03/05/2024]
Abstract
OBJECTIVES The COVID-19 pandemic changed the setting of education for many children in the U.S. Understanding COVID-19 vaccination coverage by educational setting is important for developing targeted messages, increasing parents' confidence in COVID-19 vaccines, and protecting all children from severe effects of COVID-19 infection. STUDY DESIGN/METHODS Using data from the Household Pulse Survey (n = 25,173) collected from December 9-19, 2022, January 4-16, 2023, and February 1-13, 2023, this study assessed factors associated with COVID-19 vaccination and reasons for non-vaccination among school-aged children 5-11 and adolescents 12-17 by educational setting. RESULTS Among children 5-11 years, COVID-19 vaccination coverage was higher among those who received in-person instruction (53.7%) compared to those who were homeschooled (32.5%). Furthermore, among adolescents 12-17 years, COVID-19 vaccination coverage was higher among those who received in-person instruction (73.5%) or virtual/online instruction (70.1%) compared to those who were homeschooled (51.0%). Children and adolescents were more likely to be vaccinated if the parental respondent had been vaccinated compared to those who had not. Among children and adolescents who were homeschooled, main reasons for non-vaccination were concern about side effects (45.4-51.6%), lack of trust in COVID-19 vaccines (45.0-50.9%), and lack of trust in the government (32.7-39.2%). CONCLUSIONS Children and adolescents who were home-schooled during the pandemic had lower vaccination coverage than those who attended school in person, and adolescents who were home-schooled had lower vaccination coverage than those who received virtual instruction. Based on the reasons for non-vaccination identified in this study, increasing parental confidence in vaccines, and reducing barriers to access are important for supporting COVID-19 vaccination for school-age children.

Hope for brain health: impacting the life course and society. Front Psychol 2023; 14:1214014. [PMID: 37457094 PMCID: PMC10348811 DOI: 10.3389/fpsyg.2023.1214014] [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: 05/06/2023] [Accepted: 06/16/2023] [Indexed: 07/18/2023] Open
Abstract
Hope is a cognitive process by which an individual can identify their personal goals and develop actionable steps to achieve results. It has the potential to positively impact people's lives by building resilience, and can be meaningfully experienced at both the individual and group level. Despite this significance, there are sizable gaps in our understanding of the neurobiology of hope. In this perspective paper, the authors discuss why further research is needed on hope and its potency to be harnessed in society as a "tool" to promote brain health across healthy and patient populations. Avenues for future research in hope and the brain are proposed. The authors conclude by identifying strategies for the possible applications of hope in brain health promotion within the areas of technology, arts, media, and education.

Old-age mental telehealth services at primary healthcare centers in low- resource areas in Greece: design, iterative development and single-site pilot study findings. BMC Health Serv Res 2023; 23:626. [PMID: 37312113 DOI: 10.1186/s12913-023-09583-5] [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: 02/10/2023] [Accepted: 05/19/2023] [Indexed: 06/15/2023] Open
Abstract
BACKGROUND Even though communities in low-resource areas across the globe are aging, older adult mental and cognitive health services remain mainly embedded in tertiary- or secondary hospital settings, and thus not easily accessible by older adults living in such communities. Here, the iterative development of INTegRated InterveNtion of pSychogerIatric Care (INTRINSIC) services addressing the mental and cognitive healthcare needs of older adults residing in low-resource areas of Greece is depicted. METHODS INTRINSIC was developed and piloted in three iterative phases: (i) INTRINSIC initial version conceptualization; (ii) A 5-year field testing in Andros island; and (iii) Extending the services. The INTRINSIC initial version relied on a digital platform enabling videoconferencing, a flexible battery of diagnostic tools, pharmacological treatment and psychosocial support and the active involvement of local communities in service shaping. RESULTS Ιn 61% of the 119 participants of the pilot study, new diagnoses of mental and/or neurocognitive disorders were established. INTRINSIC resulted in a significant reduction in the distance travelled and time spent to visit mental and cognitive healthcare services. Participation was prematurely terminated due to dissatisfaction, lack of interest or insight in 13 cases (11%). Based on feedback and gained experiences, a new digital platform, facilitating e-training of healthcare professionals and public awareness raising, and a risk factor surveillance system were created, while INTRINSIC services were extended to incorporate a standardized sensory assessment and the modified problem adaptation therapy. CONCLUSION The INTRINSIC model may be a pragmatic strategy to improve access of older adults with mental and cognitive disorders living in low-resource areas to healthcare services.

Study protocol for The GOAL Trial: comprehensive geriatric assessment for frail older people with chronic kidney disease to increase attainment of patient-identified goals-a cluster randomised controlled trial. Trials 2023; 24:365. [PMID: 37254217 DOI: 10.1186/s13063-023-07363-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Accepted: 05/08/2023] [Indexed: 06/01/2023] Open
Abstract
BACKGROUND An increasing number of older people are living with chronic kidney disease (CKD). Many have complex healthcare needs and are at risk of deteriorating health and functional status, which can adversely affect their quality of life. Comprehensive geriatric assessment (CGA) is an effective intervention to improve survival and independence of older people, but its clinical utility and cost-effectiveness in frail older people living with CKD is unknown. METHODS The GOAL Trial is a pragmatic, multi-centre, open-label, superiority, cluster randomised controlled trial developed by consumers, clinicians, and researchers. It has a two-arm design, CGA compared with standard care, with 1:1 allocation of a total of 16 clusters. Within each cluster, study participants ≥ 65 years of age (or ≥ 55 years if Aboriginal or Torres Strait Islander (First Nations Australians)) with CKD stage 3-5/5D who are frail, measured by a Frailty Index (FI) of > 0.25, are recruited. Participants in intervention clusters receive a CGA by a geriatrician to identify medical, social, and functional needs, optimise medication prescribing, and arrange multidisciplinary referral if required. Those in standard care clusters receive usual care. The primary outcome is attainment of self-identified goals assessed by standardised Goal Attainment Scaling (GAS) at 3 months. Secondary outcomes include GAS at 6 and 12 months, quality of life (EQ-5D-5L), frailty (Frailty Index - Short Form), transfer to residential aged care facilities, cost-effectiveness, and safety (cause-specific hospitalisations, mortality). A process evaluation will be conducted in parallel with the trial including whether the intervention was delivered as intended, any issue or local barriers to intervention delivery, and perceptions of the intervention by participants. The trial has 90% power to detect a clinically meaningful mean difference in GAS of 10 units. DISCUSSION This trial addresses patient-prioritised outcomes. It will be conducted, disseminated and implemented by clinicians and researchers in partnership with consumers. If CGA is found to have clinical and cost-effectiveness for frail older people with CKD, the intervention framework could be embedded into routine clinical practice. The implementation of the trial's findings will be supported by presentations at conferences and forums with clinicians and consumers at specifically convened workshops, to enable rapid adoption into practice and policy for both nephrology and geriatric disciplines. It has potential to materially advance patient-centred care and improve clinical and patient-reported outcomes (including quality of life) for frail older people living with CKD.

A cost-minimisation analysis comparing alternative telemedicine screening approaches for retinopathy of prematurity. J Telemed Telecare 2023; 29:196-202.

Abstract
INTRODUCTION Screening for retinopathy of prematurity (ROP) is an important procedure in the prevention of blindness in high-risk preterm infants. In the regionalised healthcare system of Queensland (Australia), outside of the major centres, some preterm infants are cared for in special care nurseries (SCNs). When necessary, infants in these nurseries who are at risk of ROP are transferred to a tertiary hospital for screening by paediatric ophthalmologists. The transport of preterm infants for eye examinations adds risk and incurs significant costs to the health system. Using a cost-minimisation approach, we aimed to compare the costs of the current ROP screening practice with two alternative telemedicine approaches. METHODS We constructed a decision analytic model to estimate costs from a health service perspective with a five-year analysis horizon; activity data from a tertiary ROP screening service were used to inform the models. The three models assessed were: (a) a digital retinal photography (DRP)-equipped travelling nurse, (b) equipping SCNs with DRP, and providing training to local nurses, and (c) current practice of infant transfer. In all cases, the tertiary centre provides specialist ophthalmologic review. RESULTS Of the three models, we estimated the most expensive option to be equipping SCNs with DRP and providing training to local nurses (AUD$4114/infant). We found that the current practice of transferring infants was the second most expensive (AUD$1021/infant). The most economical model was the specialist nurse travelling to each SCN with a portable DRP (AUD$363/infant). A sensitivity analysis, which assessed uncertainty and variability around the cost estimates, found that the ranking for the expected costs of the alternative models of care did not change. DISCUSSION This is the first economic and cost-minimisation analysis in Australia to compare the costs of the current screening programme with two alternative telemedicine approaches for screening ROP. Telemedicine programmes that facilitate non-physician screening may improve the cost efficiency of the health system while maintaining the health outcomes for children, and reducing the risk associated with infant transport.

Frailty and pain in an acute private hospital: an observational point prevalence study. Sci Rep 2023; 13:3345. [PMID: 36849461 PMCID: PMC9971208 DOI: 10.1038/s41598-023-29933-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Accepted: 02/13/2023] [Indexed: 03/01/2023] Open
Abstract
Frailty and pain in hospitalised patients are associated with adverse clinical outcomes. However, there is limited data on the associations between frailty and pain in this group of patients. Understanding the prevalence, distribution and interaction of frailty and pain in hospitals will help to determine the magnitude of this association and assist health care professionals to target interventions and develop resources to improve patient outcomes. This study reports the point prevalence concurrence of frailty and pain in adult patients in an acute hospital. A point prevalence, observational study of frailty and pain was conducted. All adult inpatients (excluding high dependency units) at an acute, private, 860-bed metropolitan hospital were eligible to participate. Frailty was assessed using the self-report modified Reported Edmonton Frail Scale. Current pain and worst pain in the last 24 h were self-reported using the standard 0-10 numeric rating scale. Pain scores were categorised by severity (none, mild, moderate, severe). Demographic and clinical information including admitting services (medical, mental health, rehabilitation, surgical) were collected. The STROBE checklist was followed. Data were collected from 251 participants (54.9% of eligible). The prevalence of frailty was 26.7%, prevalence of current pain was 68.1% and prevalence of pain in the last 24 h was 81.3%. After adjusting for age, sex, admitting service and pain severity, admitting services medical (AOR: 13.5 95% CI 5.7-32.8), mental health (AOR: 6.3, 95% CI 1. 9-20.9) and rehabilitation (AOR: 8.1, 95% CI 2.4-37.1) and moderate pain (AOR: 3.9, 95% CI 1. 6-9.8) were associated with increased frailty. The number of older patients identified in this study who were frail has implications for managing this group in a hospital setting. This indicates a need to focus on developing strategies including frailty assessment on admission, and the development of interventions to meet the care needs of these patients. The findings also highlight the need for increased pain assessment, particularly in those who are frail, for more effective pain management.Trial registration: The study was prospectively registered (ACTRN12620000904976; 14th September 2020).

Abstract
Objective This study aims to investigate the effect of physical violence and serious injury on health-related quality of life in the Australian adult population. Methods This study utilised panel data from the Household, Income and Labour Dynamics in Australia (HILDA) Survey. HRQoL was measured through the physical component summary (PCS), mental component summary (MCS), and short-form six-dimension utility index (SF-6D) of the 36-item Short-Form Health Survey (SF-36). Longitudinal fixed-effect regression models were fitted using 19 waves of the HILDA Survey spanning from 2002 to 2020. Results This study found a negative effect of physical violence and serious injury on health-related quality of life. More specifically, Australian adults exposed to physical violence and serious injury exhibited lower levels of health-related quality of life. Who experienced physical violence only had lower MCS (β = −2.786, 95% CI: −3.091, −2.481) and SF-6D (β = −0.0214, 95% CI: −0.0248, −0.0181) scores if switches from not experiencing physical violence and serious injury. Exposed to serious injury had lower PCS (β = −5.103, 95% CI: −5.203, −5.004), MCS (β = −2.363, 95% CI: −2.480, −2.247), and SF-6D (β = −0.0585, 95% CI: −0.0598, −0.0572) score if the adults not experiencing physical violence and serious injury. Further, individuals exposed to both violence and injury had substantially lower PCS (β = -3.60, 95% CI: -4.086, -3.114), MCS (β = −6.027, 95% CI: −6.596, −5.459), and SF-6D (β = −0.0716, 95% CI: −0.0779, −0.0652) scores relative to when the individuals exposed to none. Conclusion Our findings indicate that interventions to improve Australian adults’ quality of life should pay particular attention to those who have experienced physical violence and serious injury. Our findings suggest unmet mental health needs for victims of physical violence and serious injuries, which calls for proactive policy interventions that provide psychological and emotional therapy.

Abstract
INTRODUCTION Hospitalised older adults are prone to functional deterioration, which is more evident in frail older patients and can be further exacerbated by pain. Two interventions that have the potential to prevent progression of frailty and improve patient outcomes in hospitalised older adults but have yet to be subject to clinical trials are nurse-led volunteer support and technology-driven assessment of pain. METHODS AND ANALYSIS This single-centre, prospective, non-blinded, cluster randomised controlled trial will compare the efficacy of nurse-led volunteer support, technology-driven pain assessment and the combination of the two interventions to usual care for hospitalised older adults. Prior to commencing recruitment, the intervention and control conditions will be randomised across four wards. Recruitment will continue for 12 months. Data will be collected on admission, at discharge and at 30 days post discharge, with additional data collected during hospitalisation comprising records of pain assessment and volunteer support activity. The primary outcome of this study will be the change in frailty between both admission and discharge, and admission and 30 days, and secondary outcomes include length of stay, adverse events, discharge destination, quality of life, depression, cognitive function, functional independence, pain scores, pain management intervention (type and frequency) and unplanned 30-day readmissions. Stakeholder evaluation and an economic analysis of the interventions will also be conducted. ETHICS AND DISSEMINATION Ethical approval has been granted by Human Research Ethics Committees at Ramsay Health Care WA|SA (number: 2057) and Edith Cowan University (number: 2021-02210-SAUNDERS). The findings will be disseminated through conference presentations, peer-reviewed publications and social media. TRIAL REGISTRATION NUMBER ACTRN12620001173987.

Abstract
BACKGROUND As admissions to paediatric intensive care units (PICU) rise and mortality rates decline, the focus is shifting from survival to quality of survivorship. There is paucity of internationally accepted guidelines to manage complications like over-sedation, delirium, and immobility in the paediatric setting. These have a strong adverse impact on PICU recovery including healthcare costs and long-term functional disability. The A2F bundle (ABCDEF), or ICU Liberation, was developed to operationalise the multiple evidence-based guidelines addressing ICU-related complications and has been shown to improve clinical outcomes and health-care related costs in adult studies. However, there is little data on the effect of ICU Liberation bundle implementation in PICU. METHODS PICU-STARS will be a single centre before-and-after after trial and implementation study. It is designed to evaluate if the multidimensional, nurse-led ICU Liberation model of care can be applied to the PICU and if it is successful in minimising PICU-related problems in a mixed quaternary PICU. In a prospective baseline measurement, the present practises of care in the PICU will be assessed in order to inform the adaptation and implementation of the PICU Liberation bundle. To assess feasibility, implementation outcomes, and intervention effectiveness, the implementation team will use the Consolidated Framework for Implementation Research (CIFR) and process assessment (mixed methods). The implementation process will be evaluated over time, with focus groups, interviews, questionnaires, and observations used to provide formative feedback. Over time, the barriers and enablers for successful implementation will be analysed, with recommendations based on "lessons learned." All outcomes will be reported using standard descriptive statistics and analytical techniques, with appropriate allowance for patient differentials in severity and relevant characteristics. DISCUSSION The results will inform the fine-tune of the Liberation bundle adaptation and implementation process. The expected primary output is a detailed adaptation and implementation guideline, including clinical resources (and investment) required, to adopt PICU-STARS in other children's hospitals. PATIENT AND PUBLIC INVOLVEMENT STATEMENT The authors thank the PICU education and Liberation Implementation team, and our patients and families for their inspiration and valuable comments on protocol drafts. Results will be made available to critical care survivors, their caregivers, relevant societies, and other researchers. TRIAL REGISTRATION ACTRN, ACTRN382863 .

Abstract
INTRODUCTION Members of the public expect occupational therapists to provide evidence-based practice. Participation in professional development activities is essential to update knowledge and acquire skills to enable delivery of evidence-based assessment and intervention. Therapists commonly choose to participate in professional development through attending training workshops. Little is known about occupational therapists' preference of how continuing professional development training programmes should be designed and delivered. METHODS An online quantitative survey of occupational therapists working with older people in Australia, conducted June to September 2018, incorporated a discrete choice experiment to elicit and estimate preferences for professional development training when acquiring skills in delivering an evidence-based intervention. A series of questions asked participants to choose one of two options for training, each differing in terms of attributes (level of recognition, mode of learning, follow-up post-training and cost to establish willingness to pay). Statistical analyses were conducted according to recommended practice in the field of choice-modelling. RESULTS A total of 108 responses were received from occupational therapists practicing around Australia. Therapists reported a strong preference for receiving post-training support to implement their new skills in practice and would be willing to pay an additional A$200 for training that included this option. They also highly regarded achieving 'certification' in their new skill (willing to pay an additional A$100) and having the opportunity to become a 'Master Trainer' in the future (willing to pay an additional A$200). DISCUSSION This study generates new knowledge about aspects of a professional development training programme that occupational therapists' value and aspects that they are willing to compromise on when acquiring new skills that they intend to use in their practice. These findings can influence the training programme design utilised by those working in implementation research and providers of continuing professional development for health professionals.

Abstract
INTRODUCTION Frailty and pain are associated with adverse patient clinical outcomes and healthcare system costs. Frailty and pain can interact, such that symptoms of frailty can make pain assessment difficult and pain can exacerbate the progression of frailty. The prevalence of frailty and pain and their concurrence in hospital settings are not well understood, and patients with cognitive impairment are often excluded from pain prevalence studies due to difficulties assessing their pain. The aim of this study is to determine the prevalence of frailty and pain in adult inpatients, including those with cognitive impairment, in an acute care private metropolitan hospital in Western Australia. METHODS AND ANALYSIS A prospective, observational, single-day point prevalence, cross-sectional study of frailty and pain intensity of all inpatients (excluding day surgery and critical care units) will be undertaken. Frailty will be assessed using the modified Reported Edmonton Frail Scale. Current pain intensity will be assessed using the PainChek smart-device application enabling pain assessment in people unable to report pain due to cognitive impairment. Participants will also provide a numerical rating of the intensity of current pain and the worst pain experienced in the previous 24 hours. Demographic and clinical information will be collected from patient files. The overall response rate of the survey will be reported, as well as the percentage prevalence of frailty and of pain in the sample (separately for PainChek scores and numerical ratings). Additional statistical modelling will be conducted comparing frailty scores with pain scores, adjusting for covariates including age, gender, ward type and reason for admission. ETHICS AND DISSEMINATION Ethical approval has been granted by Ramsay Health Care Human Research Ethics Committee WA/SA (reference: 2038) and Edith Cowan University Human Research Ethics Committee (reference: 2020-02008-SAUNDERS).

Abstract
Recently, there has been an increase in the number of patients with allergic rhinitis (AR) and the number of publications devoted to this problem is increasing. The main etiological factors of AR are pollen of trees, meadow and weeds, as well as mold spores, household allergens and epidermis of animals. Epidemiological studies have found that the prevalence and structure of AR are influenced by regional characteristics, such as the climatic and geographical and social characteristics of the region, and successively therapeutic and preventive algorithms in AR are also different. AIM To examine the phenotype of the incidence of AR in connection with the characteristics of aeroallergens under the influence of climatic and geographical conditions in northern Vietnam, to make a new contribution to knowledge about AR in Asia and to increase the effect of treatment and prevention in this territory. MATERIALS AND RESEARCH METHODS The study was conducted in the period from 06.2018 to 09.2018 on the basis of the ENT department of Thainguyen Central Hospital, Vietnam. A total of 556 patients with pathology of ENT organs aged 18 to 70 years were examined, 158 cases of chronic rhinitis were revealed. Among data from 158 patients, 64 patients were diagnosed with AR. We used otorhinolaryngological examination, a standard specific allergological examination and carried out aeropolyneological research in the city of the northern Vietnam, from 06.2018 to 06.2019. RESULT The aerobiological spectrum is dominated by pollen from the families Moraceae, Urticaceae, Poaceae, Acacia, Artemisia, fern spores and fungal spores from the genus Alternaria. Among patients with chronic rhinitis, 40% were diagnosed with AR, 98.44% of them year-round or perennial AR, with predominant sensitization to house dust mites and molds, much more often to plant pollen. Among 9 (14.06%) patients diagnosed with a polyp of the nasal cavity, 6 (9.37%) patients had increased levels of specific IgE in the blood to a mixture of molds. Sensitization in patients with AR with hypertrophy of the mucous membrane of the nasal cavity is predominant on house dust. CONCLUSION Predominantly, AR in northern Vietnam was year-round. Especially the connection between the formation of a polyp of the nasal cavity and hypersensitivity to fungal spores has been indicated, which may also indicate the role of social factors in further recommendations for the diagnosis, treatment and prevention of AR in patients living in North Vietnam.

Making the Invisible Companion of People with Dementia Visible in Economic Studies: What Can We Learn from Social Science? Healthcare (Basel) 2021; 9:healthcare9010044. [PMID: 33466492 PMCID: PMC7824847 DOI: 10.3390/healthcare9010044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 12/22/2020] [Accepted: 12/30/2020] [Indexed: 11/16/2022] Open
Abstract
The dyadic perspective is important to understand the mutual influence and interdependence of both the person living with dementia and their care partner. This perspective is routinely adopted in social research programs for dementia and many dyadic interventions have been developed. However, economic evaluation and modelling to date has often failed to incorporate caregivers’ perspectives, and their respective costs and outcomes while giving care for the person with dementia. On the occasions that this has been done, caregivers were represented as “informal costs” associated with dementia. This limited perspective cannot incorporate two-way interactions of the dyad in economic evaluations of dementia programs. This paper provides an overview of the possible interactions between people living with dementia and care partners as discovered in social science literature in the past 20 years. We demonstrate the strength of the relationships and discuss strategies for incorporating the dyadic perspective in economic evaluations of dementia programs in the future.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of a 12-week Exercise Physiology (EP) program for people living in a residential aged care facility. METHODS A within-study pre- and postintervention design to calculate incremental cost-effectiveness ratios per quality-adjusted life years gained. A health service provider perspective was used. RESULTS Fifty-nine participants enrolled in a 12-week program. The program cost was A$514.30 per resident. At a willingness-to-pay threshold of A$64 000, the likelihood of being cost-effective of the program is approximately 60%, due to a small increase in participants' quality of life, as reported by care staff. The model showed great variance, depending on who rated the participants' quality of life outcomes. CONCLUSION It is uncertain that a 12-week EP program is cost-effective based on the evidence of the current trial. However, it appears that a low-cost program can produce small improvements for residents in care facilities.

Implementing an evidence-based dementia care program in the Australian health context: A cost-benefit analysis. HEALTH & SOCIAL CARE IN THE COMMUNITY 2020; 28:2013-2024. [PMID: 32431010 DOI: 10.1111/hsc.13013] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Revised: 02/13/2020] [Accepted: 04/14/2020] [Indexed: 06/11/2023]
Abstract
The World Health Organisation has called for the implementation of evidence-based interventions that enhance function and capability in people with dementia. In response, the Boosting Dementia Research Initiative in Australia has funded a number of projects aimed at improving such outcomes for people with dementia and their caregivers. What is not known is the economic and societal outcomes of these projects and of program implementation to the Australian healthcare system. The purpose of this study was to identify the costs and benefits of implementing an evidence-based reablement program within Australian health context. A well-used methodology familiar to governments and decision-makers was used to calculate the costs and benefits of implementing the program in Australia. Four different perspectives: market, private, efficiency (social) and referent group (key stakeholders) were considered in the cost-benefit evaluation. Almost A$6.2 million societal gain is presented through a social cost-benefit analysis. The referent (stakeholder) group analysis is used to demonstrate that people with dementia and their caregivers are the bearers of the costs and the Australian health and social care system gains the most from the program implementation. The results of this cost-benefit analysis suggest that there is a need to plan and provide subsidies or other financial incentives to assist people with dementia and their caregivers to engage in reablement programs in Australia; thus the whole society can be advantaged. Funding bodies and decision-makers are urged to recognise the potential societal benefits that can be achieved from participating in such reablement programs.

Abstract
OBJECTIVE The aim of this project was to assess the value for money of a modified unit within a residential aged care facility (RACF) for people requiring palliative care at the end of life. METHODS A three-way comparison using a mixed-method costing was used to estimate the per day cost of the unit compared to care in a palliative care unit within a hospital and a standard RACF bed. RESULTS The cost of the unit was estimated at $242 per day (2015 Australian dollars). The palliative care hospital bed cost $1,664 per day. The cost of a standard RACF bed was $123 per day, indicating that an additional $120 per day is required to provide the higher level of care required by people with complex palliative care needs. CONCLUSION A modified RACF unit could provide substantial cost savings to the health budget for selected complex palliative care patients.

Abstract
OBJECTIVE This paper reports on the valuation of quality-of-life states in the Alzheimer's Disease Five Dimensions (AD-5D) instrument in a representative sample of the general population in Australia using the discrete-choice experiment with duration (DCETTO) elicitation technique. METHOD A DCE with 200 choice sets of two quality-of-life (QoL) state-duration combinations blocked into 20 survey versions, with ten choice sets in each version, was designed and administered online to a sample representative of the Australian population. Two additional choice sets comprising internal consistency and dominance checks were included in each survey version. A range of model specifications investigating preferences with respect to duration and interactions between AD-5D dimension levels were estimated. Utility weights were developed, with estimated coefficients transformed to the 0 (being dead) to 1 (full health) scale, suitable for the calculation of quality-adjusted life-year (QALY) weights for use in economic evaluation. RESULTS In total, 1999 respondents completed the choice experiment. Overall, respondents were slightly better educated and had higher annual incomes than the Australian general population. The estimation results from different specifications and models were broadly consistent with the monotonic nature of the AD-5D: utility increased with increased life expectancy and decreased as the severity level for each dimension worsened. A utility value set was generated for the calculation of utilities for all QoL states defined by the AD-5D descriptive system. CONCLUSION The DCE-based utility value set is now available to use to generate QALYs for the economic evaluation of treatments and interventions targeting people with dementia and/or their family caregivers.

Abstract
OBJECTIVE To describe and examine the impact of a new specialist drug and alcohol brief intervention team (DABIT) model integrated into the ED on the identification of individuals at risk of future alcohol and other drug (AOD)-related harm. A cost-outcome analysis was conducted to assess the impact on costs per referral. METHODS An interrupted time series analysis examined the changes in number of referrals following the implementation of the DABIT model over 2 years (January 2015-December 2016) within a large 436-bed public hospital. The primary outcome of interest was the number of AOD-related referrals per month identified following ED presentations. The independent variables were: time (measured in months), implementation periods (pre-implementation; a transition period of adjustment during which the new DABIT model of care was developed; post-implementation period with a fully operational DABIT model); and the number of full-time equivalent staff per month to account for the increase in labour productivity. In a second time series analysis, the outcome was cost per referral per month. RESULTS After controlling for changes in labour productivity, the number of referrals was significantly higher following the implementation of the DABIT model when compared to those during the pre-implementation and transition periods. Costs were significantly lower following DABIT implementation resulting in $1096 net cost savings per referral. CONCLUSIONS Integration of a specialist brief intervention AOD model to support ED care may increase uptake of specialist AOD treatment and could be beneficial from an economic efficiency viewpoint.

Abstract
OBJECTIVE To assess the application of a structured process to consolidate the number of medication administration times for residents of aged care facilities. DESIGN A nonblinded, matched-pair, cluster randomized controlled trial. SETTING AND PARTICIPANTS Permanent residents who were English-speaking and taking at least 1 regular medication, recruited from 8 South Australian residential aged care facilities (RACFs). METHODS The intervention involved a clinical pharmacist applying a validated 5-step tool to identify opportunities to reduce medication complexity (eg, by administering medications at the same time or through use of longer-acting or combination formulations). Residents in the comparison group received routine care. The primary outcome at 4-month follow-up was the number of administration times per day for medications charted regularly. Resident satisfaction and quality of life were secondary outcomes. Harms included falls, medication incidents, hospitalizations, and mortality. The association between the intervention and primary outcome was estimated using linear mixed models. RESULTS Overall, 99 residents participated in the intervention arm and 143 in the comparison arm. At baseline, the mean resident age was 86 years, 74% were female, and medications were taken an average of 4 times daily. Medication simplification was possible for 62 (65%) residents in the intervention arm, with 57 (62%) of 92 simplification recommendations implemented at follow-up. The mean number of administration times at follow-up was reduced in the intervention arm in comparison to usual care (-0.36, 95% confidence interval -0.63 to -0.09, P = .01). No significant changes in secondary outcomes or harms were observed. CONCLUSIONS AND IMPLICATIONS One-off application of a structured tool to reduce regimen complexity is a low-risk intervention to reduce the burden of medication administration in RACFs and may enable staff to shift time to other resident care activities.

Abstract
OBJECTIVE To investigate the decision-making processes applied by people with dementia and family carers participating in using health economic approaches to value dementia-specific quality of life states. METHODS People with dementia (n = 13) and family carers (n = 14) participated in valuing quality of life states using two health economic approaches: Discrete Choice Experiment (DCE) and Best Worst Scaling (BWS). Participants were encouraged to explain their reasoning using a "Think Aloud" approach. RESULTS People with dementia and family carers adopted a range of decision-making strategies including "anchoring" the presented states against current quality of life, or simplifying the decision-making by focusing on the sub-set of attributes deemed most important. Overall, there was strong evidence of task engagement for BWS and DCE. CONCLUSIONS Health economic valuation approaches can be successfully applied with people with dementia and family carers. These data can inform the assessment of benefits from their perspectives for incorporation within economic evaluation.

Effects of temperature and viscosity on miracidial and cercarial movement of Schistosoma mansoni: ramifications for disease transmission. Int J Parasitol 2020; 50:153-159. [PMID: 31991147 DOI: 10.1016/j.ijpara.2019.12.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Revised: 12/17/2019] [Accepted: 12/23/2019] [Indexed: 10/25/2022]
Abstract
Parasites with complex life cycles can be susceptible to temperature shifts associated with seasonal changes, especially as free-living larvae that depend on a fixed energy reserve to survive outside the host. The life cycle of Schistosoma, a trematode genus containing some species that cause human schistosomiasis, has free-living, aquatic miracidial and cercarial larval stages that swim using cilia or a forked tail, respectively. The small size of these swimmers (150-350 µm) dictates that their propulsion is dominated by viscous forces. Given that viscosity inhibits the swimming ability of small organisms and is inversely correlated with temperature, changes in temperature should affect the ability of free-living larval stages to swim and locate a host. By recording miracidial and cercarial movement of Schistosoma mansoni using a high-speed camera and manipulating temperature and viscosity independently, we assessed the role each factor plays in the swimming mechanics of the parasite. We found a positive effect of temperature and a negative effect of viscosity on miracidial and cercarial speed. Reynolds numbers, which describe the ratio of inertial to viscous forces exerted on an aquatic organism, were <1 across treatments. Q10 values were <2 when comparing viscosity treatments at 20 °C and 30 °C, further supporting the influence of viscosity on miracidial and cercarial speed. Given that both larval stages have limited energy reserves and infection takes considerable energy, successful transmission depends on both speed and lifespan. We coupled our speed data with mortality measurements across temperatures and discovered that the theoretical maximum distance travelled increased with temperature and decreased with viscosity for both larval stages. Thus, our results suggest that S. mansoni transmission is high during warm times of the year, partly due to improved swimming performance of the free-living larval stages, and that increases in temperature variation associated with climate change might further increase transmission.

Cost-utility analysis comparing hospital-based intravenous immunoglobulin with home-based subcutaneous immunoglobulin in patients with secondary immunodeficiency. Vox Sang 2019; 114:237-246.

Abstract
BACKGROUND AND OBJECTIVE Immunoglobulin replacement therapy (IRT) is often used to support patients with primary immunodeficiency disease (PID) and secondary immunodeficiency disease (SID). Home-based subcutaneous immunoglobulin (SCIg) is reported to be a cheaper and more efficient option compared to hospital-based intravenous immunoglobulin (IVIg) for PID. In contrast, there is little information on the cost-effectiveness of IRT in SID. However, patients who develop hypogammaglobulinaemia secondary to other conditions (SID) have different clinical aetiology compared to PID. This study assesses whether SCIg provides a good value-for-money treatment option in patients with secondary immunodeficiency disease (SID). METHODS A Markov cohort simulation model with six health states was used to compare cost-effectiveness of IVIg with SCIg from a healthcare system perspective. The costs of treatment, infection and quality-adjusted life years (QALYs) for IVIg and SCIg treatment options were modelled with a time horizon of 10 years and weekly cycles. Deterministic and probabilistic sensitivity analyses were performed around key parameters. RESULTS The cumulative cost for IVIg was A$151 511 and for SCIg A$144 296. The QALYs with IVIg were 3·07 and with SCIg 3·51. Based on the means, SCIg is the dominant strategy with better outcomes and at lower cost. The probabilistic sensitivity analysis shows that 88·3% of the 50 000 iterations fall below the nominated willingness to pay threshold of A$50 000 per QALY. Therefore, SCIg is a cost-effective treatment option. CONCLUSION For SID patients in Queensland (Australia), the home-based SCIg treatment option provides better health outcomes and cost savings.

Abstract
Interprofessional education (IPE) programs in residential aged care facilities (RACF) contributes to the care of older adults whilst providing an environment for students to learn and practise in an interprofessional manner. Clinical placements are provided by RACF through funding and support from universities in collaboration with the RACF. Conducting a benefit-cost analysis (BCA) can determine the sustainability of a clinical placement program such as an IPE program but there is limited research reporting the economic aspects of clinical placements even though it is a university and government priority. This study provides a benefit-cost analysis of an interprofessional education program offered by a residential aged care provider in Western Australia. Analysis using a BCA methodology was conducted to provide information about the level and distribution of the costs and benefits from different analytical perspectives over the three-year period of the IPE program. The analysis showed that the program was highly beneficial from an economic efficiency viewpoint, even though it did not present a financial gain for the aged care provider. The benefits accrued mainly to students in terms of increased education and skill, and to residents in terms of health outcomes and quality of life, while the cost was mostly incurred by the care provider. An IPE program in a RACF is a valuable educational learning experience for students and is also socially beneficial for residents and the broader health sector. For IPE programs in aged care to be sustainable, they require the development of collaborative partnerships with external funding.

Abstract
BACKGROUND To evaluate a Geriatric Emergency Department Intervention (GEDI) model of service delivery for adults aged 70 years and older. METHODS A pragmatic trial of the GEDI model using a pre-post design. GEDI is a nurse-led, physician-championed, Emergency Department (ED) intervention; developed to improve the care of frail older adults in the ED. The nurses had gerontology experience and education and provided targeted geriatric assessment and streamlining of care. The final format included 2.4 full time equivalent nurses working 7 days from 0700 h to 1730 h (1530 h at weekends). There were three implementations periods: pre-implementation (2012); a developmental phase from January 2013 to August 2015; and full implementation from September 2015 to August 2016. The outcomes measured were disposition (discharged home, admitted or died); ED length of stay; hospital length of stay; all cause in-hospital mortality within 28 days; time to ED re-presentation up to 28 days post-discharge; in-hospital costs. The setting was a tertiary hospital ED, with 385 beds, in Queensland, Australia. Approximately 53,000 patients presented to the ED annually with 20% aged 70 years and older. All patients over the age 70 who presented to the ED between January 2012 and August 2016 (n = 44,983) were included in the trial. RESULTS Older persons who presented to the ED when the GEDI team were working had increased likelihoods of discharge (Hazard ratio (HR) = 1.19; 95% CI: 1.13-1.24) and reduced ED length of stay (HR = 1.42; 95% CI: 1.33-1.52) compared with those who presented when GEDI were not working. There was no increase in the risk of mortality (HR = 1.01; 95% CI = 0.23-4.43) or risk of same cause re-presentation to 28 days (HR = 1.21; 95% CI: 0.99-1.49). The GEDI service resulted in average cost savings per ED presentation of $35 [95% CI, $21, $49] and savings of $1469 [95% CI, $1105, $1834] per hospital admission. CONCLUSIONS Implementation of a nurse-led physician-championed model of ED care, focused on frail older adults, reduced ED length of stay, hospital admission and if admitted, hospital length of stay and cost, without increasing mortality or same cause re-presentation. These increases were sustained over time and after the initial implementation team had changed roles. TRIAL REGISTRATION Australian Clinical Trials Registration Number ACTRN12615001157561 - retrospectively registered on 29/10/2015. Data were retrieved via retrospective access to clinical information systems. First data access was on 1/7/2015.

Abstract
Fecal indicator bacteria (FIB) are used to assess fecal pollution levels in surface water and are among the criteria used by regulatory agencies to determine water body impairment status. While FIB provide no information about pollution source, microbial source tracking (MST) does, which contributes to more direct and cost effective remediation efforts. We studied a watershed in Florida managed for wildlife conservation that historically exceeded the state regulatory guideline for fecal coliforms. We measured fecal coliforms, enterococci, a marker gene for avian feces (GFD), and a marker gene for human-associated Bacteroides (HF183) in sediment, vegetation, and water samples collected monthly from six sites over two years to: 1) assess the influence of site, temporal factors, and habitat (sediment, vegetation, and water) on FIB and MST marker concentrations, 2) test for correlations among FIB and MST markers, and 3) determine if avian feces and/or human sewage contributed to FIB levels. Sediment and vegetation had significantly higher concentrations of FIB and GFD compared to water and thus may serve as microbial reservoirs, providing unreliable indications of recent contamination. HF183 concentrations were greatest in water samples but were generally near the assay limit of detection. HF183-positive results were attributed to white-tailed deer (Odocoileus virginianus) feces, which provided a false indication of human sewage in this water body. FIB and GFD were positively correlated while FIB and HF183 were negatively correlated. We demonstrated that birds, not sewage, were the main source of FIB, thus avoiding implementation of a total maximum daily load program (TMDL). Our results demonstrate that the concomitant use of FIB and MST can improve decision-making and provide direction when water bodies are impaired, and provides a strategy for natural source exclusion in water bodies impacted by wild animal feces.

Abstract
INTRODUCTION Generic instruments for assessing health-related quality of life may lack the sensitivity to detect changes in health specific to certain conditions, such as dementia. The Quality of Life in Alzheimer's Disease (QOL-AD) is a widely used and well-validated condition-specific instrument for assessing health-related quality of life for people living with dementia, but it does not enable the calculation of quality-adjusted life years, the basis of cost utility analysis. This study will generate a preference-based scoring algorithm for a health state classification system -the Alzheimer's Disease Five Dimensions (AD-5D) derived from the QOL-AD. METHODS AND ANALYSIS Discrete choice experiments with duration (DCETTO) and best-worst scaling health state valuation tasks will be administered to a representative sample of 2000 members of the Australian general population via an online survey and to 250 dementia dyads (250 people with dementia and their carers) via face-to-face interview. A multinomial (conditional) logistic framework will be used to analyse responses and produce the utility algorithm for the AD-5D. ETHICS AND DISSEMINATION The algorithms developed will enable prospective and retrospective economic evaluation of any treatment or intervention targeting people with dementia where the QOL-AD has been administered and will be available online. Results will be disseminated through journals that publish health economics articles and through professional conferences. This study has ethical approval.

[PMID: 29329559 PMCID: PMC5767065 DOI: 10.1186/s13063-017-2417-2] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2017] [Accepted: 12/16/2017] [Indexed: 12/25/2022] Open
Abstract
Background Complex medication regimens are highly prevalent in residential aged care facilities (RACFs). Strategies to reduce unnecessary complexity may be valuable because complex medication regimens can be burdensome for residents and are costly in terms of nursing time. The aim of this study is to investigate application of a structured process to simplify medication administration in RACFs. Methods SImplification of Medications Prescribed to Long-tErm care Residents (SIMPLER) is a non-blinded, matched-pair, cluster randomised controlled trial of a single multidisciplinary intervention to simplify medication regimens. Trained study nurses will recruit English-speaking, permanent residents from eight South Australian RACFs. Medications taken by residents in the intervention arm will be assessed once using a structured tool (the Medication Regimen Simplification Guide for Residential Aged CarE) to identify opportunities to reduce medication regimen complexity (e.g. by administering medications at the same time, or through the use of longer-acting or combination formulations). Residents in the comparison group will receive routine care. Participants will be followed for up to 36 months after study entry. The primary outcome measure will be the total number of charted medication administration times at 4 months after study entry. Secondary outcome measures will include time spent administering medications, medication incidents, resident satisfaction, quality of life, falls, hospitalisation and mortality. Individual-level analyses that account for clustering will be undertaken to determine the impact of the intervention on the study outcomes. Discussion Ethical approval has been obtained from the Monash University Human Research Ethics Committee and the aged care provider organisation. Research findings will be disseminated through conference presentations and peer-reviewed publications. SIMPLER will enable an improved understanding of the burden of medication use in RACFs and quantify the impact of regimen simplification on a range of outcomes important to residents and care providers.

An economic model of advance care planning in Australia: a cost-effective way to respect patient choice. BMC Health Serv Res 2017; 17:797. [PMID: 29191183 PMCID: PMC5709848 DOI: 10.1186/s12913-017-2748-4] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2017] [Accepted: 11/20/2017] [Indexed: 11/10/2022] Open
Abstract
Background Advance care planning (ACP) is a process of planning for future health and personal care. A person’s values and preferences are made known so that they can guide decision making at a future time when that person cannot make or communicate his or her decisions. This is particularly relevant for people with dementia because their ability to make decisions progressively deteriorates over time. This study aims to evaluate the cost-effectiveness of delivering a nationwide ACP program within the Australian primary care setting. Methods A decision analytic model was developed to identify the costs and outcomes of an ACP program for people aged 65+ years who were at risk of developing dementia. Inputs for the model was sourced and estimated from the literature. The reliability of the results was thoroughly tested in sensitivity analyses. Results The results showed that, compared to usual care, a nationwide ACP program for people aged 65+ years who were at risk of dementia would be cost-effective. However, the results only hold if ACP completion is higher than 50% and adherence to ACP wishes is above 75%. Conclusions A nationwide ACP program in the primary care setting is a cost-effective or cost-saving intervention compared to usual care in a population at-risk of developing dementia. Cost savings are generated from providing treatment and care that is consistent with patient preferences, resulting in fewer hospitalisations and less-intensive care at end-of-life.

A structure, process and outcome evaluation of the Geriatric Emergency Department Intervention model of care: a study protocol. BMC Geriatr 2017; 17:76. [PMID: 28330452 PMCID: PMC5363028 DOI: 10.1186/s12877-017-0462-z] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2016] [Accepted: 03/10/2017] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Emergency departments are chaotic environments in which complex, frail older persons living in the community and residential aged care facilities are sometimes subjected to prolonged emergency department lengths of stay, excessive tests and iatrogenic complications. Given the ageing population, the importance of providing appropriate, quality health care in the emergency department for this cohort is paramount. One possible solution, a nurse-led, physician-championed, emergency department gerontological intervention team, which provides frontload assessment, early collateral communication and appropriate discharge planning, has been developed. The aim of this Geriatric Emergency Department Intervention is to maximise the quality of care for this vulnerable cohort in a cost effective manner. METHODS The Geriatric Emergency Department Intervention research project consists of three interrelated studies within a program evaluation design. The research comprises of a structure, process and outcome framework to ascertain the overall utility of such a program. The first study is a pre-post comparison of the Geriatric Emergency Department Intervention in the emergency department, comparing the patient-level outcomes before and after service introduction using a quasi-experimental design with historical controls. The second study is a descriptive qualitative study of the structures and processes required for the operation of the Geriatric Emergency Department Intervention and clinician and patient satisfaction with service models. The third study is an economic evaluation of the Geriatric Emergency Department Intervention model of care. DISCUSSION There is a paucity of evidence in the literature to support the implementation of nurse-led teams in emergency departments designed to target frail older persons living in the community and residential aged care facilities. This is despite the high economic and patient morbidity and mortality experienced in these vulnerable cohorts. This research project will provide guidance related to the optimal structures and processes required to implement the model of care and the associated cost related outcomes.

Developing a dementia-specific health state classification system for a new preference-based instrument AD-5D. Health Qual Life Outcomes 2017; 15:21. [PMID: 28122626 PMCID: PMC5264482 DOI: 10.1186/s12955-017-0585-0] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2016] [Accepted: 01/07/2017] [Indexed: 11/17/2022] Open
Abstract
Background With an ageing population, the number of people with dementia is rising. The economic impact on the health care system is considerable and new treatment methods and approaches to dementia care must be cost effective. Economic evaluation requires valid patient reported outcome measures, and this study aims to develop a dementia-specific health state classification system based on the Quality of Life for Alzheimer’s disease (QOL-AD) instrument (nursing home version). This classification system will subsequently be valued to generate a preference-based measure for use in the economic evaluation of interventions for people with dementia. Methods We assessed the dimensionality of the QOL-AD to develop a new classification system. This was done using exploratory and confirmatory factor analysis and further assessment of the structure of the measure to ensure coverage of the key areas of quality of life. Secondly, we used Rasch analysis to test the psychometric performance of the items, and select item(s) to describe each dimension. This was done on 13 items of the QOL-AD (excluding two general health items) using a sample of 284 residents living in long-term care facilities in Australia who had a diagnosis of dementia. Results A five dimension classification system is proposed resulting from the three factor structure (defined as ‘interpersonal environment’, ‘physical health’ and ‘self-functioning’) derived from the factor analysis and two factors (‘memory’ and ‘mood’) from the accompanying review. For the first three dimensions, Rasch analysis selected three questions of the QOL-AD (‘living situation’, ‘physical health’, and ‘do fun things’) with memory and mood questions representing their own dimensions. The resulting classification system (AD-5D) includes many of the health-related quality of life dimensions considered important to people with dementia, including mood, global function and skill in daily living. Conclusions The development of the AD-5D classification system is an important step in the future application of the widely used QOL-AD in economic evaluations. Future valuation studies will enable this tool to be used to calculate quality adjusted life years to evaluate treatments and interventions for people diagnosed with mild to moderate dementia.

Pressure injury in Australian public hospitals: a cost-of-illness study. AUST HEALTH REV 2016; 39:329-336. [PMID: 25725696 DOI: 10.1071/ah14088] [Citation(s) in RCA: 110] [Impact Index Per Article: 13.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2014] [Accepted: 11/25/2014] [Indexed: 11/23/2022]
Abstract
OBJECTIVE Pressure injuries (PI) are largely preventable and can be viewed as an adverse outcome of a healthcare admission, yet they affect millions of people and consume billions of dollars in healthcare spending. The existing literature in Australia presents a patchy picture of the economic burden of PI on society and the health system. The aim of the present study was to provide a more comprehensive and updated picture of PI by state and severity using publicly available data. METHODS A cost-of-illness analysis was conducted using a prevalence approach and a 1-year time horizon based on data from the existing literature extrapolated using simulation methods to estimate the costs by PI severity and state subgroups. RESULTS The treatment cost across all states and severity in 2012-13 was estimated to be A$983 million per annum, representing approximately 1.9% of all public hospital expenditure or 0.6% of the public recurrent health expenditure. The opportunity cost was valued at an additional A$820 million per annum. These estimates were associated with a total number of 121 645 PI cases in 2012-13 and a total number of 524 661 bed days lost. CONCLUSIONS The costs estimated in the present study highlight the economic waste for the Australian health system associated with a largely avoidable injury. Wastage can also be reduced by preventing moderate injuries (Stage I and II) from developing into severe cases (Stage III and IV), because the severe cases, accounting for 12% of cases, mounted to 30% of the total cost.

Expression of a mutant prohibitin from the aP2 gene promoter leads to obesity-linked tumor development in insulin resistance-dependent manner. Oncogene 2016; 35:4459-70. [PMID: 26751773 DOI: 10.1038/onc.2015.501] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2015] [Revised: 10/19/2015] [Accepted: 11/14/2015] [Indexed: 12/26/2022]
Abstract
A critical unmet need for the study of obesity-linked cancer is the lack of preclinical models that spontaneously develop obesity and cancer sequentially. Prohibitin (PHB) is a pleiotropic protein that has a role in adipose and immune functions. We capitalized on this attribute of PHB to develop a mouse model for obesity-linked tumor. We achieved this by expressing Y114F-PHB (m-PHB) from the aP2 gene promoter for simultaneous manipulation of adipogenic and immune signaling functions. The m-PHB mice develop obesity in a sex-neutral manner, but only male mice develop impaired glucose homeostasis and hyperinsulinemia similar to transgenic mice expressing PHB. Interestingly, only male m-PHB mice develop histiocytosis with lymphadenopathy, suggesting that metabolic dysregulation or m-PHB alone is not sufficient for the tumor development and that both are required for tumorigenesis. Moreover, ovariectomy in female m-PHB mice resulted in impaired glucose homeostasis, hyperinsulinemia and consequently tumor development similar to male m-PHB mice. These changes were not observed in sham-operated control m-Mito-Ob mice, further confirming the role of obesity-related metabolic dysregulation in tumor development in m-PHB mice. Our data provide a proof-of-concept that obesity-associated hyperinsulinemia promotes tumor development by facilitating dormant mutant to manifest and reveals a sex-dimorphic role of PHB in adipose-immune interaction or immunometabolism. Targeting PHB may provide a unique opportunity for the modulation of immunometabolism in obesity, cancer and in immune diseases.

Cost-Effectiveness of Repetitive Transcranial Magnetic Stimulation versus Antidepressant Therapy for Treatment-Resistant Depression. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2015; 18:597-604. [PMID: 26297087 DOI: 10.1016/j.jval.2015.04.004] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/08/2014] [Revised: 03/13/2015] [Accepted: 04/03/2015] [Indexed: 05/16/2023]
Abstract
BACKGROUND Repetitive transcranial magnetic stimulation (rTMS) therapy is a clinically safe, noninvasive, nonsystemic treatment for major depressive disorder. OBJECTIVE We evaluated the cost-effectiveness of rTMS versus pharmacotherapy for the treatment of patients with major depressive disorder who have failed at least two adequate courses of antidepressant medications. METHODS A 3-year Markov microsimulation model with 2-monthly cycles was used to compare the costs and quality-adjusted life-years (QALYs) of rTMS and a mix of antidepressant medications (including selective serotonin reuptake inhibitors, serotonin and norepinephrine reuptake inhibitors, tricyclics, noradrenergic and specific serotonergic antidepressants, and monoamine oxidase inhibitors). The model synthesized data sourced from published literature, national cost reports, and expert opinions. Incremental cost-utility ratios were calculated, and uncertainty of the results was assessed using univariate and multivariate probabilistic sensitivity analyses. RESULTS Compared with pharmacotherapy, rTMS is a dominant/cost-effective alternative for patients with treatment-resistant depressive disorder. The model predicted that QALYs gained with rTMS were higher than those gained with antidepressant medications (1.25 vs. 1.18 QALYs) while costs were slightly less (AU $31,003 vs. AU $31,190). In the Australian context, at the willingness-to-pay threshold of AU $50,000 per QALY gain, the probability that rTMS was cost-effective was 73%. Sensitivity analyses confirmed the superiority of rTMS in terms of value for money compared with antidepressant medications. CONCLUSIONS Although both pharmacotherapy and rTMS are clinically effective treatments for major depressive disorder, rTMS is shown to outperform antidepressants in terms of cost-effectiveness for patients who have failed at least two adequate courses of antidepressant medications.

Abstract
BACKGROUND Treatment uptake amongst patients with chronic Hepatitis C virus (HCV) in Australia is relatively low. New approaches to assessment have the potential to reduce public waiting lists, improve access to treatment, and to reduce healthcare costs. AIM To describe the costs to the public hospital system and waiting time associated with a novel integrated rapid access to assessment and treatment (RAAT) model of care that utilizes Transient Elastography (TE) as a specialist outpatient-based approach for a streamlined assessment of patients with chronic HCV, compared to conventional outpatient management with liver biopsy (LB). METHODS Time from first medical review to treatment plan and costs associated with detection of fibrosis were recorded for patients receiving RAAT during a 3-month period, and for a similar historical cohort managed conventionally with LB. Costs related to medical and multidisciplinary team reviews and the TE/LB test itself were included. RESULTS Patients receiving RAAT had lower costs (n = 27, median AU$2716) and shorter time to treatment (median = 194 days) than for conventional management (n = 13, median $5005, 420 days; p < 0.01). Differences related to the lower TE test costs and the lower cost of consults between first medical review and establishment of a treatment plan. CONCLUSIONS Based on real world audit data, this evaluation suggests TE, used as part of a new RAAT model of care, is cost saving to the health system in the short-term and reduces waiting times. The analysis reported here was intended to assess the costs related to detection of fibrosis, and is limited by the small sample size and potential selection bias. Future research should undertake a full economic evaluation at a whole of service level, to consider a more comprehensive and longer-term assessment of the costs and benefits associated with HCV management.

Disparities in child mortality trends in two new states of India. BMC Public Health 2013; 13:779. [PMID: 23978236 PMCID: PMC3765884 DOI: 10.1186/1471-2458-13-779] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2013] [Accepted: 08/21/2013] [Indexed: 11/28/2022] Open
Abstract
Background India has the world’s highest total number of under-five deaths of any nation. While progress towards Millennium Development Goal 4 has been documented at the state level, little information is available for greater disaggregation of child health markers within states. In 2000, new states were created within the country as a partial response to political pressures. State-level information on child health trends in the new states of Chhattisgarh and Jharkhand is scarce. To fill this gap, this article examines under-five and neonatal mortality across various equity markers within these two new states, pre-and post-split. Methods Both direct and indirect estimation using pooled data from five available sources were undertaken. Inter-population disparities were evaluated by mortality data stratification of rural–urban location, ethnicity, wealth and districts. Results Both states experienced an overall reduction in under-five and neonatal mortality, however, this has stagnated post-2001 and various disparities persist. In cases where disparities have declined, such as between urban–rural populations and low- and high-income groups, this has been driven by modest declines within the disadvantaged groups (i.e. low-income rural households) and stagnation or worsening of outcomes within the advantaged groups. Indeed, rising trends in mortality are most prevalent in urban middle-income households. Conclusions The results suggest that rural health improvements may have come at the expense of urban areas, where poor performance may be attributed to factors such as lack of access to quality private health facilities. In addition, the disparities may in part be associated with geographical access, traditional practices and district-level health resource allocation.

Disparities in child mortality trends: what is the evidence from disadvantaged states in India? the case of Orissa and Madhya Pradesh. Int J Equity Health 2013; 12:45.

Abstract
Introduction The Millennium Development Goals prompted renewed international efforts to reduce under-five mortality and measure national progress. However, scant evidence exists about the distribution of child mortality at low sub-national levels, which in diverse and decentralized countries like India are required to inform policy-making. This study estimates changes in child mortality across a range of markers of inequalities in Orissa and Madhya Pradesh, two of India’s largest, poorest, and most disadvantaged states. Methods Estimates of under-five and neonatal mortality rates were computed using seven datasets from three available sources – sample registration system, summary birth histories in surveys, and complete birth histories. Inequalities were gauged by comparison of mortality rates within four sub-state populations defined by the following characteristics: rural–urban location, ethnicity, wealth, and district. Results Trend estimates suggest that progress has been made in mortality rates at the state levels. However, reduction rates have been modest, particularly for neonatal mortality. Different mortality rates are observed across all the equity markers, although there is a pattern of convergence between rural and urban areas, largely due to inadequate progress in urban settings. Inter-district disparities and differences between socioeconomic groups are also evident. Conclusions Although child mortality rates continue to decline at the national level, our evidence shows that considerable disparities persist. While progress in reducing under-five and neonatal mortality rates in urban areas appears to be levelling off, polices targeting rural populations and scheduled caste and tribe groups appear to have achieved some success in reducing mortality differentials. The results of this study thus add weight to recent government initiatives targeting these groups. Equitable progress, particularly for neonatal mortality, requires continuing efforts to strengthen health systems and overcome barriers to identify and reach vulnerable groups.

Abstract
OBJECTIVE To estimate the association between local clean indoor air ordinances and prenatal maternal smoking across 351 municipalities in Massachusetts before the 2004 statewide ban and to test the effect of time since ordinance adoption on the association. METHODS The authors linked 2002 birth certificate data of women who gave birth in the state and reported a Massachusetts residence (n=67,584) to a database of indoor smoking ordinances in all municipalities. Multilevel regression models accounting for individual- and municipality-level variables estimate the associations between the presence of local smoking ordinances, strength of the ordinances, time since ordinance adoption and prenatal smoking. RESULTS Compared with those living in municipalities with no ordinances, women living in municipalities with a smoking ordinance had lower odds of prenatal smoking (OR=0.72, CI=0.53 to 0.98). No effect was found for 100% smoke-free ordinances. For the analyses testing the effect of time, pregnant women living in municipalities with ordinances enacted >2 years were less likely to smoke than those in municipalities with more recent (<1 year) ordinances. CONCLUSIONS Preventing smoking among women of reproductive age is a public health priority. This study suggests that indoor smoking ordinances were associated with lower prenatal smoking prevalence and the favourable effect increased over time. Findings highlight the public health benefit of tobacco control policies.

Abstract
BACKGROUND Few previous studies have examined non-wealth-based inequalities in child mortality within developing countries. This study estimates changes in under-5-year-olds and neonatal mortality in Nepal across a range of subnational levels, which allows us to assess the degree of equity in Nepal's progress towards Millennium Development Goal 4. METHODS Direct estimates of under-5-year-olds and neonatal death rates were generated for 1990-2005 using three Demographic and Health Surveys and two Living Standards Surveys by the following levels: national, rural/urban location, ecological region, development region, ethnicity and wealth. Absolute and relative inequalities were measured by rate differences and rate ratios, respectively. Additionally, wealth-related inequality was calculated using slope and relative indexes of inequality and concentration indices. RESULTS Estimates suggest that while most rates of under-5-year-olds and neonatal mortality have declined across the different equity markers, leading to a downward trend in absolute inequalities, relative inequalities appear to have remained stable over time. The decline in absolute inequalities is strongest for under-5-year-olds' mortality, with no statistically significant trend in either relative or absolute inequalities found for neonatal mortality. A possible increase in inequalities, at least in relative terms, was found across development regions, where death rates remain high in the mid-western region. CONCLUSIONS By 2015, our estimates suggest that more than 65% of deaths of under-5-year-olds will occur in the neonatal period, with stable trends in neonatal mortality inequalities. These findings along with the fact that health outcomes for neonates are more highly dependent on health systems, suggest further equitable reductions in under-5-year-olds mortality will require broad health-system strengthening, with a focus on the improvement of healthcare services provided for mothers and newborns. Other inequities suggest continued special attention for vulnerable subpopulations is warranted, particularly to overcome social exclusion and financial barriers to care in urban areas.

Stagnant neonatal mortality and persistent health inequality in middle-income countries: a case study of the Philippines. PLoS One 2013; 8:e53696.

Abstract
BACKGROUND The probability of survival through childhood continues to be unequal in middle-income countries. This study uses data from the Philippines to assess trends in the prevalence and distribution of child mortality and to evaluate the country's socioeconomic-related child health inequality. METHODOLOGY Using data from four Demographic and Health Surveys we estimated levels and trends of neonatal, infant, and under-five mortality from 1990 to 2007. Mortality estimates at national and subnational levels were produced using both direct and indirect methods. Concentration indices were computed to measure child health inequality by wealth status. Multivariate regression analyses were used to assess the contribution of interventions and socioeconomic factors to wealth-related inequality. FINDINGS Despite substantial reductions in national under-five and infant mortality rates in the early 1990s, the rates of declines have slowed in recent years and neonatal mortality rates remain stubbornly high. Substantial variations across urban-rural, regional, and wealth equity-markers are evident, and suggest that the gaps between the best and worst performing sub-populations will either be maintained or widen in the future. Of the variables tested, recent wealth-related inequalities are found to be strongly associated with social factors (e.g. maternal education), regional location, and access to health services, such as facility-based delivery. CONCLUSION The Philippines has achieved substantial progress towards Millennium Development Goal 4, but this success masks substantial inequalities and stagnating neonatal mortality trends. This analysis supports a focus on health interventions of high quality--that is, not just facility-based delivery, but delivery by trained staff at well-functioning facilities and supported by a strong referral system--to re-start the long term decline in neonatal mortality and to reduce persistent within-country inequalities in child health.

Abstract
Background Recent assessments show continued decline in child mortality in Papua New Guinea (PNG), yet complete subnational analyses remain rare. This study aims to estimate under-five mortality in PNG at national and subnational levels to examine the importance of geographical inequities in health outcomes and track progress towards Millennium Development Goal (MDG) 4. Methodology We performed retrospective data validation of the Demographic and Health Survey (DHS) 2006 using 2000 Census data, then applied advanced indirect methods to estimate under-five mortality rates between 1976 and 2000. Findings The DHS 2006 was found to be unreliable. Hence we used the 2000 Census to estimate under-five mortality rates at national and subnational levels. During the period under study, PNG experienced a slow reduction in national under-five mortality from approximately 103 to 78 deaths per 1,000 live births. Subnational analyses revealed significant disparities between rural and urban populations as well as inter- and intra-regional variations. Some of the provinces that performed the best (worst) in terms of under-five mortality included the districts that performed worst (best), with district-level under-five mortality rates correlating strongly with poverty levels and access to services. Conclusions The evidence from PNG demonstrates substantial within-province heterogeneity, suggesting that under-five mortality needs to be addressed at subnational levels. This is especially relevant in countries, like PNG, where responsibility for health services is devolved to provinces and districts. This study presents the first comprehensive estimates of under-five mortality at the district level for PNG. The results demonstrate that for countries that rely on few data sources even greater importance must be given to the quality of future population surveys and to the exploration of alternative options of birth and death surveillance.

Abstract
Management Case Studies describe approaches to real-life management problems in health systems. Each installment is a brief description of a problem and how it was dealt with. The cases are intended to help readers deal with similar experiences in their own work sites. Problem solving, not hypothesis testing, is emphasized. Successful resolution of the management issue is not a criterion for publication--important lessons can be learned from failures, too.

Abstract
Because the outcome of a large clinical series of patients with juxtaposition of the atrial appendages (JAA) has not previously been reported, a retrospective study was performed on patients diagnosed with JAA at a tertiary medical center. Patients with JAA were identified through a computerized database search, and echocardiograms and medical records of patients with JAA were reviewed. Twenty-two patients with JAA were identified, with an overall incidence of 0.28%. All but 2 patients were diagnosed prospectively with JAA by echocardiography. The lesion-specific incidences and associated lesions were similar to those of large autopsy and surgical series. Abnormal conotruncal anatomy was more frequently seen with juxtaposition of the right atrial appendage (JRAA) vs juxtaposition of the left atrial appendage (JLAA) (14/15 vs 4/7), as was atrial outlet obstruction (6/15 vs 2/7). JLAA was more frequently associated with complex atrioventricular anatomy (3/7 vs 1/15). Patients with JAA underwent single ventricle palliation in 11/22 cases with 6 deaths; biventricular repair was performed in 8/22 cases with no deaths. Surgical outcomes for patients with JRAA and JLAA were similar, and survival was predominantly influenced by suitability for biventricular repair.

Abstract
OBJECTIVE Antibodies directed against general and specific target-organ autoantigens are present in the sera of human patients and animal models with autoimmune disease. The relevance of these autoantibodies to the disease process remains ambiguous in most cases. In autoimmune exocrinopathy (Sjögren's syndrome), autoantibodies to the intracellular nuclear proteins SSA/Ro and SSB/La, as well as the cell surface muscarinic cholinergic receptor (M3) are observed. To evaluate the potential role of these factors in the loss of secretory function of exocrine tissues, a panel of monoclonal and polyclonal antibodies was developed for passive transfer into the NOD animal model. METHODS Monoclonal antibodies to mouse SSB/La, rat M3 receptor, and a rabbit polyclonal antiparotid secretory protein antibody were obtained for this study. These antibody reagents were subsequently infused into NOD-scid mice. Saliva flow rates were subsequently monitored over a 72-hour period. Submandibular gland lysates were examined by Western blotting for alteration of the distribution of the water channel protein aquaporin (AQP). RESULTS Evaluation of the secretory response indicated that only antibodies directed toward the extracellular domains of the M3 receptor were capable of mediating the exocrine dysfunction aspect of the clinical pathology of the autoimmune disease. In vitro stimulation with a muscarinic agonist of submandibular gland cells isolated from mice treated with anti-M3 antibody, but not saline or the isotype control, failed to translocate AQP to the plasma membrane. CONCLUSION These findings define a clear role for the humoral immune response and the targeting of the cell surface M3 signal transduction receptor as primary events in the development of clinical symptoms of autoimmune exocrinopathy. Furthermore, the anti-M3 receptor activity may negatively affect the secretory response through perturbation of normal signal transduction events, leading to translocation of the epithelial cell water channel.

Abstract
Chlorpheniramine (chlorphenamine, CPAM) is a racemic antihistaminic H1 drug containing two enantiomers. The aim of this study was to assess the bioequivalence of two formulations (reference and Vietnamese-tested formulation) of racemic chlorpheniramine combined with phenylpropanolamine in an open-labeled, randomized, crossover two-period study, after administration of 8 mg of racemic chlorpheniramine in 12 healthy Vietnamese subjects. First, dissolution of both formulations was tested in vitro according to USP requirements. Then the 12 subjects received both formulations after an overnight fast and a 7-day wash-out period. Plasma samples were collected up to 168 h. Plasma concentrations of total chlorpheniramine and its individual enantiomers were determined with a validated chiral HPLC method and pharmacokinetic parameters were estimated using model-independent analysis. For the reference formulation, Cmax and AUC values were higher for (+)S-chlorpheniramine ((+)S-CPAM) compared to (-)R-chlorpheniramine ((-)R-CPAM) (13.3 vs. 6.8 ng/ml and 409 vs. 222 ng/ml/h, respectively) while Clt/F and Vd/F were lower (9.8 vs. 17.6 l/h and 321 vs. 627 l, respectively). No difference was observed for Tmax, t(1/2), and MRT. Pharmacokinetic parameters were similar for the reference and the Vietnamese-tested formulation. Bioequivalence was assessed by Schuirmann test, as recommended by the current FDA and European Community criteria. Dissolution tests showed that both formulations were equivalent. A nonstereospecific, but not a stereospecific, approach indicated bioequivalence between the formulations.
