Cost-utility analysis of Dexcom G6 real-time continuous glucose monitoring versus FreeStyle Libre 1 intermittently scanned continuous glucose monitoring in adults with type 1 diabetes in Belgium

AIMS/HYPOTHESIS

The aim of this study was to assess the long-term cost-effectiveness of Dexcom G6 real-time continuous glucose monitoring (rtCGM) with alert functionality compared with FreeStyle Libre 1 intermittently scanned continuous glucose monitoring (isCGM) without alerts in adults with type 1 diabetes in Belgium.

METHODS

The IQVIA CORE Diabetes Model was used to estimate cost-effectiveness. Input data for the simulated baseline cohort were sourced from the randomised ALERTT1 trial (ClinicalTrials.gov.

REGISTRATION NO

NCT03772600). The age of the participants was 42.9 ± 14.1 years (mean ± SD), and the baseline HbA1c was 57.8 ± 9.5 mmol/mol (7.4 ± 0.9%). Participants using rtCGM showed a reduction in HbA1c of 3.6 mmol/mol (0.36 percentage points) based on the 6-month mean between-group difference. In the base case, both rtCGM and isCGM were priced at €3.92/day (excluding value-added tax [VAT]) according to the Belgian reimbursement system. The analysis was performed from a Belgian healthcare payer perspective over a lifetime time horizon. Health outcomes were expressed as quality-adjusted life years. Probabilistic and one-way sensitivity analyses were used to account for parameter uncertainty.

RESULTS

In the base case, rtCGM dominated isCGM, resulting in lower diabetes-related complication costs and better health outcomes. The associated main drivers favouring rtCGM were lower HbA1c, fewer severe hypoglycaemic events and reduced fear of hypoglycaemia. The results were robust under a wide range of one-way sensitivity analyses. In models where the price of rtCGM is €5.11/day (a price increase of 30.4%) or €12.34/day (a price increase of 214.8%), rtCGM was cost-neutral or reached an incremental cost-effectiveness ratio of €40,000 per quality-adjusted life year, respectively.

CONCLUSIONS/INTERPRETATION

When priced similarly, Dexcom G6 rtCGM with alert functionality has both economic and clinical benefits compared with FreeStyle Libre 1 isCGM without alerts in adults with type 1 diabetes in Belgium, and appears to be a cost-effective glucose monitoring modality. Trial registration ClinicalTrials.gov NCT03772600.

Treatment Response Following Adaptive PASAT Training for Depression Vulnerability: a Systematic Review and Meta-Analysis

In recent years, cognitive control training (CCT) has gained momentum as an intervention to remediate cognitive impairments and decrease depressive symptoms. One promising operationalization to train cognitive control is the adaptive Paced Auditory Serial Addition Task (aPASAT). In this systematic review and meta-analysis of aPASAT training, the efficacy of the intervention and potential moderators were examined. The PsycINFO, MEDLINE, Embase, Web of Science and Cochrane Library electronic databases were searched for studies examining aPASAT training for depressive symptomatology or rumination. Nineteen studies (n = 1255) were included, comprising of depressed patients, remitted depressed patients, at-risk, and healthy participants. We found small significant effects directly after training for both depressive symptomatology and rumination, with similar effect sizes at follow-up. Subgroup analyses suggest a significantly higher mean effect of aPASAT training in non-healthy populations for rumination immediately following training, but not for depressive symptomatology. The amount of training sessions did not moderate effects of CCT. aPASAT has a small but significant effect on depressive symptoms, with direct effects immediately after training, as well as sustained long-term effects. It is currently unclear how many sessions are required for sustained effects due to heterogeneity in training dosage and absence of sufficient trials. Our results suggest that aPASAT training may be most effective for at-risk, remitted- and clinically depressed populations. The effect sizes resulting from this meta-analysis could be used to adequately power future research, which could investigate a dose-response relationship and examine potential treatment gains when combining CCT with other antidepressant interventions.

Cost-Utility of an Exercise Referral Scheme Versus Doing Nothing in Flemish Adults: Exploring the Impact of Key Assumptions

BACKGROUND

This health-economic evaluation assessed the cost-effectiveness of an exercise referral scheme (ERS) versus doing nothing in the Flemish region (Belgium), with a particular focus on the impact of several scenarios.

METHODS

A 14-state Markov model was applied to compare the expected costs and quality-adjusted life years (QALYs) of 2 alternatives: the Flemish ERS (2019 data, mean age 52 y, 69.1% women) and doing nothing. A health care payer perspective was adopted and a lifetime time horizon was applied. A set of 18 scenario analyses is presented. In addition, univariate and probabilistic sensitivity analyses were performed.

RESULTS

Under the assumptions selected for the base-case analysis, the Flemish ERS is moderately cost-effective compared with doing nothing, with an incremental cost-utility ratio of €28,609/QALY. Based on the scenario analyses, the results largely depend on the assumptions regarding the continuation of the intervention effect and the frequency with which the intervention is repeated. The greatest health gains can be made when a sustainable behavioral change is achieved among participants. The probabilistic sensitivity analysis confirmed that the cost-effectiveness results were not robust.

CONCLUSIONS

If it is possible to induce a sustainable behavioral change with an intervention delivered at 2- or 5-year intervals, then the Flemish ERS is potentially cost-effective compared with doing nothing (given a €40,000/QALY threshold). These results suggest the importance of repeated implementation of the program together with careful monitoring of the adherence and the sustainability of the observed effects in a real-world setting.

The impact of the COVID-19 pandemic on delayed care of cardiovascular diseases in Europe: a systematic review

AIMS

Cardiovascular diseases (CVD) are the leading cause of death worldwide. The coronavirus disease 2019 (COVID-19) pandemic has disrupted healthcare systems, causing delays in essential medical services, and potentially impacting CVD treatment. This study aims to estimate the impact of the pandemic on delayed CVD care in Europe by providing a systematic overview of the available evidence.

METHODS AND RESULTS

PubMed, Embase, and Web of Science were searched until mid-September 2022 for studies focused on the impact of delayed CVD care due to the pandemic in Europe among adult patients. Outcomes were changes in hospital admissions, mortality rates, delays in seeking medical help after symptom onset, delays in treatment initiation, and change in the number of treatment procedures. We included 132 studies, of which all were observational retrospective. Results were presented in five disease groups: ischaemic heart diseases (IHD), cerebrovascular accidents (CVA), cardiac arrests (CA), heart failures (HF), and others, including broader CVD groups. There were significant decreases in hospital admissions for IHD, CVA, HF and urgent and elective cardiac procedures, and significant increases for CA. Mortality rates were higher for IHD and CVA.

CONCLUSION

The pandemic led to reduced acute CVD hospital admissions and increased mortality rates. Delays in seeking medical help were observed, while urgent and elective cardiac procedures decreased. Adequate resource allocation, clear guidelines on how to handle care during health crises, reduced delays, and healthy lifestyle promotion should be implemented. The long-term impact of pandemics on delayed CVD care, and the health-economic impact of COVID-19 should be further evaluated.

Impact of the COVID-19 pandemic on delayed care of cardiovascular diseases in Europe: a systematic review

BACKGROUND

Cardiovascular diseases remain the foremost global cause of death. The COVID-19 pandemic has strained health-care systems, leading to delays in essential medical services, including treatment for cardiovascular diseases. We aimed to examine the impact of the pandemic on delayed cardiovascular care in Europe.

METHODS

In this systematic review, we searched PubMed, Embase, and Web of Science for peer-reviewed and published quantitative studies in English from Nov 1, 2019, to Sept 18, 2022, that addressed pandemic-induced delays in cardiovascular disease care for adult patients in Europe. Data appraisal, extraction, and quality assessment were done by two reviewers using the 14-item QualSyst tool checklist. We extracted summary patient-level data from the studies, including around 3·5 million patients. Evaluated outcomes included changes pre-March 2020 and during the COVID-19 pandemic in hospital admissions, mortality rates, medical help-seeking delays post-symptom onset, treatment initiation delays, and treatment procedure counts. The protocol is registered on PROSPERO (CRD42022354443).

FINDINGS

Of the 132 included studies (20% from the UK), all were observational retrospective, with 87% focusing on the first wave of the pandemic. Results were categorised into five disease groups: ischaemic heart diseases, cerebrovascular diseases, cardiac arrests, heart failures, and others. Hospital admissions showed significant decreases around the ranges of 12-66% for ischaemic heart diseases, 9-40% for cerebrovascular diseases, 9-66% for heart failures, 27-88% for urgent and elective cardiac procedures, and an increase between 11-56% for cardiac arrests. Mortality rates were significantly higher during the pandemic, ranging between 1-25% (vs 16-22% before the pandemic) for ischaemic heart diseases and 8-70% (vs 8-26% before the pandemic) for cerebrovascular diseases. Only one study ranked low in quality.

INTERPRETATION

The pandemic led to reduced acute CVD hospital admissions and increased mortality rates. Delays in seeking medical help were observed, while urgent and elective cardiac procedures decreased. Policymakers and health-care systems should work together on implementing adequate resource allocation strategies and clear guidelines on how to handle care during health crises, reducing diagnosis and treatment initiation delays, and promoting a healthy lifestyle. Future studies should evaluate the long-term impact of pandemics on delayed CVD care, and the health-economic impact of COVID-19.

Evaluating the health and health economic impact of the COVID-19 pandemic on delayed cancer care in Belgium: A Markov model study protocol

INTRODUCTION

Cancer causes a substantial burden to our society, both from a health and an economic perspective. To improve cancer patient outcomes and lower society expenses, early diagnosis and timely treatment are essential. The recent COVID-19 crisis has disrupted the care trajectory of cancer patients, which may affect their prognosis in a potentially negative way. The purpose of this paper is to present a flexible decision-analytic Markov model methodology allowing the evaluation of the impact of delayed cancer care caused by the COVID-19 pandemic in Belgium which can be used by researchers to respond to diverse research questions in a variety of disruptive events, contexts and settings.

METHODS

A decision-analytic Markov model was developed for 4 selected cancer types (i.e. breast, colorectal, lung, and head and neck), comparing the estimated costs and quality-adjusted life year losses between the pre-COVID-19 situation and the COVID-19 pandemic in Belgium. Input parameters were derived from published studies (transition probabilities, utilities and indirect costs) and administrative databases (epidemiological data and direct medical costs). One-way and probabilistic sensitivity analyses are proposed to consider uncertainty in the input parameters and to assess the robustness of the model's results. Scenario analyses are suggested to evaluate methodological and structural assumptions.

DISCUSSION

The results that such decision-analytic Markov model can provide are of interest to decision makers because they help them to effectively allocate resources to improve the health outcomes of cancer patients and to reduce the costs of care for both patients and healthcare systems. Our study provides insights into methodological aspects of conducting a health economic evaluation of cancer care and COVID-19 including insights on cancer type selection, the elaboration of a Markov model, data inputs and analysis.

Health Economic Evaluation of Cognitive Control Training for Depression: Key Considerations

Depression is a serious and burdensome psychiatric illness that contributes heavily to health expenditures. These costs are partly related to the observation that depression is often not limited to a single episode but can recur or follow a chronic pathway. In terms of risk factors, it is acknowledged that cognitive impairments play a crucial role in vulnerability to depression. Within this context, cognitive control training (CCT) has shown its effectiveness in reducing the risk for recurrence of depression. CCT is low cost intensive and can be provided as a web-based intervention, which makes it easy to disseminate. Despite increasing interest in the field, studies examining the cost-effectiveness of CCT in the context of depression are largely missing. Health economic evaluation (HEE) allows to inform decision makers with evidence-based insights about how to spend limited available (financial) resources in the most efficient way. HEE studies constitute a crucial step in the implementation of a new intervention in clinical practice. Approaching preventive measures for depression such as CCT from an HEE perspective is informative to health policy, fostering optimal use of health expenditures. The aim of this paper was to inform and guide researchers during the phase of designing HEE studies in the context of CCT for depression. A clear view of CCT's cost-effectiveness is paramount for its clinical implementation.

Cost effectiveness review of text messaging, smartphone application, and website interventions targeting T2DM or hypertension

Digital health interventions have been shown to be clinically-effective for type 2 diabetes mellitus (T2DM) and hypertension prevention and treatment. This study synthesizes and compares the cost-effectiveness of text-messaging, smartphone application, and websites by searching CINAHL, Cochrane Central, Embase, Medline and PsycInfo for full economic or cost-minimisation studies of digital health interventions in adults with or at risk of T2DM and/or hypertension. Costs and health effects are synthesised narratively. Study quality appraisal using the Consensus on Health Economic Criteria (CHEC) list results in recommendations for future health economic evaluations of digital health interventions. Of 3056 records identified, 14 studies are included (7 studies applied text-messaging, 4 employed smartphone applications, and 5 used websites). Ten studies are cost-utility analyses: incremental cost-utility ratios (ICUR) vary from dominant to €75,233/quality-adjusted life year (QALY), with a median of €3840/QALY (interquartile range €16,179). One study finds no QALY difference. None of the three digital health intervention modes is associated with substantially better cost-effectiveness. Interventions are consistently cost-effective in populations with (pre)T2DM but not in populations with hypertension. Mean quality score is 63.0% (standard deviation 13.7%). Substandard application of time horizon, sensitivity analysis, and subgroup analysis next to transparency concerns (regarding competing alternatives, perspective, and costing) downgrades quality of evidence. In conclusion, smartphone application, text-messaging, and website-based interventions are cost-effective without substantial differences between the different delivery modes. Future health economic studies should increase transparency, conduct sufficient sensitivity analyses, and appraise the ICUR more critically in light of a reasoned willingness-to-pay threshold.Registration: PROSPERO (CRD42021247845).

Cost of illness in patients with post-treatment Lyme disease syndrome in Belgium

BACKGROUND

A proportion of patients with Lyme borreliosis (LB) report long-term persisting signs and symptoms, even after recommended antibiotic treatment, which is termed post-treatment Lyme disease syndrome (PTLDS). Consensus on guidance regarding diagnosis and treatment is currently lacking. Consequently, patients suffer and are left searching for answers, negatively impacting their quality of life and healthcare expenditure. Yet, health economic data on PTLDS remain scarce. The aim of this article is therefore to assess the cost-of-illness related to PTLDS, including the patient perspective.

METHODS

PTLDS patients (N = 187) with confirmed diagnosis of LB were recruited by a patient organization. Patients completed a self-reported questionnaire on LB-related healthcare utilization, absence from work and unemployment. Unit costs (reference year 2018) were obtained from national databases and published literature. Mean costs and uncertainty intervals were calculated via bootstrapping. Data were extrapolated to the Belgian population. Generalized linear models were used to determine associated covariates with total direct costs and out-of-pocket expenditures.

RESULTS

Mean annual direct costs amounted to €4618 (95% CI €4070-5152), of which 49.5% were out-of-pocket expenditures. Mean annual indirect costs amounted to €36 081 (€31 312-40 923). Direct and indirect costs at the population level were estimated at €19.4 and 151.5 million, respectively. A sickness or disability benefit as source of income was associated with higher direct and out-of-pocket costs.

CONCLUSIONS

The economic burden associated with PTLDS on patients and society is substantial, with patients consuming large amounts of non-reimbursed healthcare resources. Guidance on adequate diagnosis and treatment of PTLDS is needed.

Personalized remotely guided preventive exercise therapy for a healthy heart (PRIORITY): protocol for an assessor-blinded, multicenter randomized controlled trial

Aims

A key treatment for patients with varying stages of heart failure with preserved ejection fraction (HFpEF) is exercise. Yet, despite a Class 1A recommendation, only one-third of patients exercise sufficiently. A huge treatment gap exists between guidelines and clinical practice. PRIORITY aims to establish the feasibility, clinical effectiveness and cost-effectiveness of a hybrid centre and home-based personalized exercise and physical activity intervention for patients along the HFpEF continuum.

Methods

An assessor-blinded, multicenter randomized controlled trial will be conducted among 312 patients along the HFpEF continuum. Participants will be randomized (1:1) to the PRIORITY intervention or a comparator group receiving only a written exercise prescription. Participants in the PRIORITY group will receive 18 supervised centre-based exercise sessions during one year, supplemented with a remotely guided home-based physical activity program. Outcomes will be assessed at baseline, 4 months, one and two years. The primary outcome is the peak oxygen uptake (pVO2) at 1-year. Secondary outcomes include physical activity, other physical fitness parameters, cardiovascular health, echocardiographic parameters, health-related quality of life and costs at 1-year FU. Machine learning algorithms will analyse big data on physical activity collected during the 1-year intervention to develop models that can predict physical activity uptake and adherence as well as changes in fitness and health. A cost-utility analysis will be performed to evaluate the cost-effectiveness of the PRIORITY intervention compared to the control condition.

Discussion

We anticipate that participants in the supervised home-based exercise intervention group will have a greater increase in pVO2 compared to those receiving a written exercise prescription.

Effectiveness, reach, uptake, and feasibility of digital health interventions for adults with type 2 diabetes: a systematic review and meta-analysis of randomised controlled trials

BACKGROUND

Digital health interventions have shown promising results for the management of type 2 diabetes, but a comparison of the effectiveness and implementation of the different modes is not currently available. Therefore, this study aimed to compare the effectiveness of SMS, smartphone application, and website-based interventions on improving glycaemia in adults with type 2 diabetes and report on their reach, uptake, and feasibility.

METHODS

In this systematic review and meta-analysis, we searched CINAHL, Cochrane Central, Embase, MEDLINE, and PsycInfo on May 25, 2022, for randomised controlled trials (RCTs) that examined the effectiveness of digital health interventions in reducing glycated haemoglobin A1c (HbA1c) in adults with type 2 diabetes, published in English from Jan 1, 2009. Screening was carried out using Covidence, and data were extracted following Cochrane's guidelines. The primary endpoint assessed was the change in the mean (and 95% CI) plasma concentration of HbA1c at 3 months or more. Cochrane risk of bias 2 was used to assess risk of bias. Data on reach, uptake, and feasibility were summarised narratively and data on HbA1c reduction were synthesised in a meta-analysis. Grading of Recommendations, Assessment, Development, and Evaluation criteria was used to evaluate the level of evidence. The study was registered with PROSPERO, CRD42021247845.

FINDINGS

Of the 3236 records identified, 56 RCTs from 24 regions (n=11 486 participants), were included in the narrative synthesis, and 26 studies (n=4546 participants) in the meta-analysis. 20 studies used SMS as the primary mode of delivery of the digital health intervention, 25 used smartphone applications, and 11 implemented interventions via websites. Smartphone application interventions reported higher reach compared with SMS and website-based interventions, but website-based interventions reported higher uptake compared with SMS and smartphone application interventions. Effective interventions, in general, included people with greater severity of their condition at baseline (ie, higher HbA1c) and administration of a higher dose intensity of the intervention, such as more frequent use of smartphone applications. Overall, digital health intervention group participants had a -0·30 (95% CI -0·42 to -0·19) percentage point greater reduction in HbA1c, compared with control group participants. The difference in HbA1c reduction between groups was statistically significant when interventions were delivered through smartphone applications (-0·42% [-0·63 to -0·20]) and via SMS (-0·37% [-0·57 to -0·17]), but not when delivered via websites (-0·09% [-0·64 to 0·46]). Due to the considerable heterogeneity between included studies, the level of evidence was moderate overall.

INTERPRETATION

Smartphone application and SMS interventions, but not website-based interventions, were associated with better glycaemic control. However, the studies' heterogeneity should be recognised. Considering that both smartphone application and SMS interventions are effective for diabetes management, clinicians should consider factors such as reach, uptake, patient preference, and context of the intervention when deciding on the mode of delivery of the intervention. Nine in ten people worldwide own a feature phone and can receive SMS and four in five people have access to a smartphone, with numerous smartphone applications being available for diabetes management. Clinicians should familiarise themselves with this modality of programme delivery and encourage people with type 2 diabetes to use evidence-based applications for improving their self-management of diabetes. Future research needs to describe in detail the mediators and moderators of the effectiveness and implementation of SMS and smartphone application interventions, such as the optimal dose, frequency, timing, user interface, and communication mode to both further improve their effectiveness and to increase their reach, uptake, and feasibility.

Effectiveness, reach, uptake, and feasibility of digital health interventions for adults with hypertension: a systematic review and meta-analysis of randomised controlled trials

BACKGROUND

Digital health interventions are effective for hypertension self-management, but a comparison of the effectiveness and implementation of the different modes of interventions is not currently available. This study aimed to compare the effectiveness of SMS, smartphone application, and website interventions on improving blood pressure in adults with hypertension, and to report on their reach, uptake, and feasibility.

METHODS

In this systematic review and meta-analysis we searched CINAHL Complete, Cochrane Central Register of Controlled Trials, Ovid Embase, Ovid MEDLINE, and APA PsycInfo on May 25, 2022, for randomised controlled trials (RCTs) published in English from Jan 1, 2009, that examined the effectiveness of digital health interventions on reducing blood pressure in adults with hypertension. Screening was carried out using Covidence, and data were extracted following Cochrane's guidelines. The primary endpoint was change in the mean of systolic blood pressure. Risk of bias was assessed with Cochrane Risk of Bias 2. Data on systolic and diastolic blood pressure reduction were synthesised in a meta-analysis, and data on reach, uptake and feasibility were summarised narratively. Grading of Recommendations, Assessment, Development, and Evaluation criteria were used to evaluate the level of evidence. The study was registered with PROSPERO CRD42021247845.

FINDINGS

Of the 3235 records identified, 29 RCTs from 13 regions (n=7592 participants) were included in the systematic review, and 28 of these RCTs (n=7092 participants) were included in the meta-analysis. 11 studies used SMS as the primary mode of delivery of the digital health intervention, 13 used smartphone applications, and five used websites. Overall, digital health intervention group participants had a -3·62 mm Hg (95% CI -5·22 to -2·02) greater reduction in systolic blood pressure, and a -2·45 mm Hg (-3·83 to -1·07) greater reduction in diastolic blood pressure, compared with control group participants. No statistically significant differences between the three different modes of delivery were observed for both the systolic (p=0·73) and the diastolic blood pressure (p=0·80) outcomes. Smartphone application interventions had a statistically significant reduction in diastolic blood pressure (-2·45 mm Hg [-4·15 to -0·74]); however, there were no statistically significant reductions for SMS interventions (-1·80 mm Hg [-4·60 to 1·00]) or website interventions (-3·43 mm Hg [-7·24 to 0·38]). Due to the considerable heterogeneity between included studies and the high risk of bias in some, the level of evidence was assigned a low overall score. Interventions were more effective among people with greater severity of hypertension at baseline. SMS interventions reported higher reach and smartphone application studies reported higher uptake, but differences were not statistically significant.

INTERPRETATION

SMS, smartphone application, and website interventions were associated with statistically and clinically significant systolic and diastolic blood pressure reductions, compared with usual care, regardless of the mode of delivery of the intervention. This conclusion is tempered by the considerable heterogeneity of included studies and the high risk of bias in most. Future studies need to describe in detail the mediators and moderators of the effectiveness and implementation of these interventions, to both further improve their effectiveness as well as increase their reach, uptake, and feasibility.

How do people living with chronic conditions and their informal caregivers experience primary care? A phenomenological-hermeneutical study

AIMS AND OBJECTIVES

Gaining insight in how people living with chronic conditions experience primary healthcare within their informal network.

BACKGROUND

The primary healthcare system is challenged by the increasing number of people living with chronic conditions. To strengthen chronic care management, literature and policy plans point to a person-centred approach of care (PCC). A first step to identify an appropriate strategy to implement PCC is to gain more insight into the care experiences of these people and their informal caregivers.

DESIGN

A phenomenological-hermeneutical philosophy is used. The study is in line with the Consolidated Criteria for Reporting Qualitative Research Guidelines (COREQ).

METHOD

In-depth, semi-structured interviews with people living with chronic conditions and informal caregiver dyads (PCDs) (n = 16; 32 individuals) were conducted. An open-ended interview guide was used to elaborate on the PCDs' experiences regarding primary care. A purposive, maximal variation sampling was applied to recruit the participants.

RESULTS

Based on sixteen PCDs' reflections, ten themes were identified presenting their experiences with primary care and described quality care as listening and giving attention to what people with chronic conditions want, to what they strive for, and above all to promote their autonomy in a context wherein they are supported by a team of formal caregivers, family and friends.

CONCLUSION

To meet the PCDs' needs, self-management should be addressed in an interprofessional environment in which the PCD is an important partner. The findings may facilitate a shift to encourage PCDs in their strengths by enabling them to share their personal goals and by working towards meaningful activities in team collaboration.

RELEVANCE TO CLINICAL PRACTICE

Three strategies-self-management support, goal-oriented care, and interprofessional collaboration-have been suggested to improve the PCDs' primary care experiences. These strategies could guide nursing practice in using more and improve high-quality nursing care.

Creating space to talk about patients' personal goals: experiences from primary care stakeholders

BACKGROUND

To address the many challenges health systems and communities face, primary care is constantly searching for new strategies to improve quality of care. One of the strategies is to focus on patients' personal goals to direct the care process. To adopt an explicit focus on patients' personal goals, actions at different levels are required. As a first step in this process, this study aims to explore the experiences of primary care stakeholders (i.e., scholars, primary care providers, and policy makers) and develop a comprehensive understanding on the idea 'putting patients' goals first'. This will help to formulate suggestions about what these actions should include.

METHOD

In this study, 41 primary care stakeholders participating in six focus groups between January 2020 and September 2020, were recruited via maximal variation purposive sampling. Data collection was done through an open-ended semi-structured interview guide. Focus groups were audio-recorded, transcribed verbatim, and analyzed following a phenomenological-hermeneutical philosophy of Lindseth and Norberg.

RESULTS

All participants expressed a strong fundamental belief for putting patients' personal goals first. The primary care providers shared that they created space for patients' personal goals by letting them talk about their values and stories. They reported to integrate their medical expertise with patients' personal goals in order to develop a balanced relationship. In this context, they also talked about the importance of taking into account the perspectives of patients' significant others. Primary care providers also talked about how they used patients' personal goals as a guide in interprofessional collaboration. Scholars denoted that (future) care providers need more training to acquire competencies to discuss patients' personal goals. The providers and policy makers talked about organizational limitations in terms of time restrictions and the lack of registration systems to support a workflow oriented towards patients' personal goals.

CONCLUSIONS

This study can be used to support the coherence of the development of different actions and strategies to get primary care stakeholders fully on board to support the adoption of patients' personal goals in care delivery at different levels. However, models of practice and policy plans are needed to work towards a person-centered integrated system.

What are the economic dimensions of occupational health and how should they be measured? A qualitative study

Background

Decision makers want to know if there is a financial benefit in investing scarce resources in occupational health management (OHM). Economic evaluations (EEs) of OHM-strategies try to answer this question. However, EEs of OHM-strategies which are strongly marked by quantitative methods may be limited by contextual, qualitative residuals. Therefore, the objectives of this study were to (1) explore important economic dimensions of OHM and (2) to discuss the methods used in current EEs for measuring these dimensions.

Methods

In this explorative qualitative study, OHM-specialists were recruited via the Swiss organisation for health promotion. Thirteen semi-structured interviews were performed from November 2020 until May 2021. Videotapes were transcribed verbatim and organised by using an open coding strategy. Codes were clustered and synthesised as themes (i.e. the dimensions of EEs of OHM) through a mix of inductive and deductive content analysis. Member check with eight participants was accomplished to validate the results.

Results

The interviews had an average duration of 70.5 min and yielded 609 individual codes. These codes were merged into 28 subcategories which were finally categorised into five main themes: Understanding of OHM, costs, benefits, environmental aspects, and evaluation of OHM. Participants stated that the greater part of costs and benefits cannot be quantified or monetised and thus, considered in quantitative EEs. For example, they see a culture of health as key component for a successful OHM-strategy. However, the costs to establish such a culture as well as its benefits are hard to quantify. Participants were highly critical of the use of absenteeism as a linear measure of productivity. Furthermore, they explained that single, rare events, such as a change in leadership, can have significant impact on employee health. However, such external influence factors are difficult to control.

Conclusions

Participants perceived costs and benefits of OHM significantly different than how they are represented in current EEs. According to the OHM-specialists, most benefits cannot be quantified and thus, monetised. These intangible benefits as well as critical influencing factors during the process should be assessed qualitatively and considered in EEs when using them as a legitimation basis vis-à-vis decision makers.

Cost-effectiveness of exercise referral schemes: a systematic review of health economic studies

Background

This systematic review aimed to provide an overview of the existing literature on cost-effectiveness of exercise referral schemes (ERSs).

Methods

A systematic search was performed in MEDLINE, EMBASE, EconLit, Web of Science and PsycINFO. Main inclusion criteria were: (1) insufficiently active people; (2) ERSs and (3) full health economic evaluations. No publication year limits were applied. The methodological quality was assessed independently by two reviewers using the Consensus Health Economic Criteria (CHEC) checklist.

Results

Fifteen eligible publications were retrieved, presenting results of 12 different studies. Compared with usual care, ERSs were found to be cost-effective in a majority of the analyses, but with modest health gains and costs per individual. These cost-effectiveness results were also sensitive to small changes in input parameters. Two studies found that ERSs combined with a pedometer/accelerometer are cost-effective, compared with usual ERS practice. Two other studies found that an ERS with phone support and an ERS with face-to-face support might be equally effective, with similar costs.

Conclusion

Although the literature demonstrated that ERSs could be cost-effective compared with usual care, these results were not robust. Based on a small number of studies, ERSs could be optimized by using tracking devices, or by providing a choice to the participants about the delivery mode. There is need for clarity on the effectiveness of and attendance to ERS, as more certainty about these key input parameters will strengthen health-economic evidence, and thus will allow to provide a clearer message to health policy-makers.

Oral healthcare delivery in institutionalised older people: A health-economic evaluation

OBJECTIVES

This health-economic evaluation aimed to assess the cost-effectiveness of a number of alternatives for preventive and curative oral health care in institutionalised older people in Flanders.

METHODS

A six-state Markov model was used to compare expected costs and healthy oral years (HOYs) of four alternatives: (1) usual care; (2) on-site preventive care; (3) on-site preventive care + curative care in the community; and (4) on-site preventive care + on-site curative care. A healthcare payer perspective was adopted, and the time horizon was 10 years. Deterministic and probabilistic sensitivity analyses were performed.

RESULTS

Incremental cost-effectiveness ratios (ICERs) of alternatives 2, 3 and 4 (all compared to alternative 1) were as follows: (2) 7944 €/HOY gained; (3) 1576 €/HOY gained; and (4) 1132 €/HOY gained. Hence, alternatives 2 and 3 were not cost-effective compared to alternative 4. The probability that oral care interventions are more effective and cost-saving than usual care was <3% for all three interventions.

CONCLUSIONS

For institutionalised older people, on-site solutions for preventive and curative oral health care might be the most cost-effective alternative. It should be kept in mind that on-site solutions require large initial investment and that the advanced age of the population and the high costs of oral health care make it unlikely that these interventions would become cost-saving, even in the long term.

Cost-effectiveness and cost-benefit of worksite health promotion programs in Europe: a systematic review

BACKGROUND

The aim of this study was to assess the evidence regarding economic evaluations of worksite health promotion programs in Europe.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the literature search, study selection, data extraction and quality appraisal were performed independently by two researchers. Full economic evaluations of worksite health promotion programs carried out in a European workplace were included.

RESULTS

From 1728 search results, 39 articles describing 37 studies were included. Regarding methodological quality, 9 studies were rated as strong, 15 as moderate and 15 as weak. Six of the studies fulfilled the minimum standard for health economic evaluations. Worksite health promotion was applied in many different forms for a wide range of settings. Cost-effectiveness, cost-benefit and cost-utility analyses were performed from different perspectives. Effects on health outcomes tended to be small and uncertain. Only 9 out of 21 cost-benefit analyses reported a financial benefit and 10 out of 23 cost-effectiveness analyses concluded that the intervention was cost-effective. Two out of eight cost-utility analyses were found to be cost-effective. Productivity loss accounted for more than 85% of the total costs and thus, was the main cost driver in the analyses.

CONCLUSIONS

Due to considerable heterogeneity, no specific type of intervention could be identified to be particularly effective and the economic value of worksite health promotion remains uncertain. Further studies, investigating comprehensive worksite health promotion programs are needed to provide evidence on their efficiency. Guidelines to perform economic evaluations in the field of worksite health promotion, especially for valuation of productivity loss, are required.

Evaluating Large-Scale Integrated Care Projects: The Development of a Protocol for a Mixed Methods Realist Evaluation Study in Belgium

BACKGROUND

The twelve Integrated Care Program pilot projects (ICPs) created by the government plan 'Integrated Care for Better Health' aim to achieve four outcome types (the Quadruple Aim) for people with chronic diseases in Belgium: improved population health, improved patient and provider experiences and improved cost efficiency. The aim of this article is to present the development of a mixed methods realist evaluation of this large-scale, whole system change programme.

METHODS

A scientific team was commissioned to co-design and implement an evaluation protocol in close collaboration with the government, the ICPs and several other involved stakeholders.

RESULTS

A protocol for a mixed methods realist evaluation was developed to gain insights into the mechanisms that foster successful results in ICPs. The qualitative evaluation proposed will be based on the document analysis of yearly ICP progress reports, selected case studies and focus group interviews with stakeholders. Processes and outcomes of all the projects will be monitored using indicators based on administrative data on population health and the quality and costs of care. A yearly survey will be organized to collect data on patient-reported outcomes and experiences and on provider-reported measures of inter-professional collaboration and proper wellbeing. Using both quantitative and qualitative data, we will develop theories about the mechanisms and the associated contextual factors that lead to integrated care and the Quadruple Aim outcomes.

DISCUSSION

The objective of this study is to deliver policy recommendations on strategies and best practices to improve care integration in Belgium and to implement a sustainable monitoring system that serves both policy makers and the stakeholders within the ICPs. Some challenges due to the large scale of the project and the multiple stakeholders involved may impede the successful implementation of this proposal.

Cost-effectiveness of an in-home respite care program to support informal caregivers of persons with dementia: A model-based analysis

OBJECTIVES

To evaluate cost-effectiveness of an in-home respite care program in addition to standard community-based dementia care to support informal caregivers of persons with dementia compared with standard community-based dementia care.

METHODS

An age-dependent decision-analytic Markov model was applied from a third-party payer and a societal perspective projecting results of a quasi-experimental study over a time horizon of 5 years assuming a repetition of the program every 6 months. Additionally, to deal with uncertainty and to test robustness of the model scenario, one-way and probabilistic sensitivity analyses were conducted.

RESULTS

Implementing the program resulted in a quality-adjusted life year (QALY) gain of 0.14 in favor of the invention group compared with controls and an incremental cost of 1270€ from the third-party payer perspective and of 1220€ from the societal perspective. Next, an incremental cost-effectiveness ratio of 9042€/QALY and of 8690€/QALY was found in the base case, from the third-party payer perspective and the societal perspective, respectively. The scenario, one-way sensitivity, and probabilistic analyses demonstrated robustness of the base-case results.

CONCLUSION

This cost-effectiveness analysis suggests that an in-home respite care program in addition to standard community-based dementia care is a cost-effective approach compared with standard community-based dementia care only. These findings provide more insight into the value of such services for the patient, the caregiver, and for society.

Cost-utility analysis of lifestyle interventions to prevent type 2 diabetes in women with prior gestational diabetes

BACKGROUND

To compare estimated costs and health outcomes of lifestyle interventions for the prevention of type 2 diabetes mellitus in women who had gestational diabetes.

METHODS

An age-specific Markov model was applied comparing costs and quality-adjusted life years (QALYs) of three alternatives: 'doing nothing'; an annual reminder system (ARS) with an awareness campaign ('ARS-awareness'); and an ARS with an intensive lifestyle intervention ('ARS-ILS'). A healthcare payer perspective was adopted, the time horizon was 30 years and the setting was Flanders (Belgium). Sensitivity analyses were performed.

RESULTS

'ARS-awareness' was extendedly dominated. Per 10 000 participants, 'ARS-ILS' cost €13 210 256 more and gained 496 QALYs compared with 'doing nothing' (26 632 €/QALY), with a 63% probability of being cost effective, given a cost effectiveness threshold of 35 000 €/QALY. A scenario analysis showed that 'ARS-ILS' for 15 years only offered to women with prediabetes (compared with 'doing nothing') has an 89.5% likelihood of being dominant.

CONCLUSIONS

'ARS-ILS' may be the preferred intervention. However, the probability of being cost effective was low. Based on further scenario analyses, we recommend healthcare decision makers to consider the application of a more intensive alternative, focused on the highest risk profiles and with a shorter intervention duration.

A model-based economic evaluation of four newborn screening strategies for cystic fibrosis in Flanders, Belgium

Objectives: The most cost-effective newborn screening strategy for cystic fibrosis (CF) for Flanders, Belgium, is unknown. The aim of this study was to assess the cost-effectiveness of four existing newborn screening strategies for CF: IRT-DNA (immunoreactive trypsinogen, cystic fibrosis transmembrane conductance regulator (CFTR) gene mutation analysis), IRT-PAP (pancreatitis-associated protein), IRT-PAP-DNA, and IRT-PAP-DNA-EGA (extended CFTR gene analysis).Methods: Using data from published literature, the cost-effectiveness of the screening strategies was calculated for a hypothetical cohort of 65,606 newborns in Flanders, Belgium. A healthcare payer perspective was used, and the direct medical costs associated with screening were taken into account. The robustness of the model outcomes was assessed in sensitivity analyses.Results: The IRT-PAP strategy was the most cost-effective strategy in terms of costs per CF case detected (€9314 per CF case detected). The IRT-DNA strategy was more costly (€13,966 per CF case detected), but with an expected sensitivity of 93.4% also the most effective strategy, and was expected to detect 2.2 more cases of CF than the IRT-PAP strategy. The incremental cost-effectiveness ratio of IRT-DNA vs. IRT-PAP was €54,180/extra CF case detected. The IRT-PAP-DNA strategy and the IRT-PAP-DNA-EGA strategy were both strongly dominated by the IRT-PAP strategy.Conclusion: The IRT-PAP strategy was the most cost-effective strategy in terms of costs per CF case detected. However, the strategy did not fulfil the European Cystic Fibrosis Society guidelines for sensitivity and positive predictive value. Therefore, the more costly and more effective IRT-DNA strategy may be the most appropriate newborn screening strategy for Flanders.

Universal Mental Health Interventions for Children and Adolescents: A Systematic Review of Health Economic Evaluations

BACKGROUND

Effective mental health interventions may reduce the impact that mental health problems have on young people's well-being. Nevertheless, little is known about the cost effectiveness of such interventions for children and adolescents.

OBJECTIVES

The objectives of this systematic review were to summarize and assess recent health economic evaluations of universal mental health interventions for children and adolescents aged 6-18 years.

METHODS

Four electronic databases were searched for relevant health economic studies, using a pre-developed search algorithm. Full health economic evaluations evaluating the cost effectiveness of universal mental health interventions were included, as well as evaluations of anti-bullying and suicide prevention interventions that used a universal approach. Studies on the prevention of substance abuse and those published before 2013 fell outside the scope of this review. Study results were summarised in evidence tables, and each study was subject to a systematic quality appraisal.

RESULTS

Nine studies were included in the review; in six, the economic evaluation was conducted alongside a clinical trial. All studies except one were carried out in the European Union, and all but one evaluated school-based interventions. All evaluated interventions led to positive incremental costs compared to their comparators and most were associated with small increases in quality-adjusted life-years. Almost half of the studies evaluated the cost effectiveness of cognitive behavioural therapy-based interventions aimed at the prevention of depression or anxiety, with mixed results. Cost-effectiveness estimates for a parenting programme, a school-based social and emotional well-being programme and anti-bullying interventions were promising, though the latter were only evaluated for the Swedish context. Drivers of cost effectiveness were implementation costs; intervention effectiveness, delivery mode and duration; baseline prevalence; and the perspective of the evaluation. The overall study quality was reasonable, though most studies only assessed short-term costs and effects.

CONCLUSION

Few studies were found, which limits the possibility of drawing strong conclusions about cost effectiveness. There is some evidence based on decision-analytic modelling that anti-bullying interventions represent value for money. Generally, there is a lack of studies that take into account long-term costs and effects.

Health economic evaluations of interventions to increase physical activity and decrease sedentary behavior at the workplace: a systematic review

Objective The workplace is an ideal setting to implement public health strategies, but economic justification for such interventions is needed. Therefore, we performed a critical appraisal and synthesis of health economic evaluations (HEE) of workplace interventions aiming to increase physical activity (PA) and/or decrease sedentary behavior (SB). Methods A comprehensive search filter was developed using appropriate guidelines, such as the Peer Review of Electronic Search Strategies (PRESS) checklist, and published search algorithms. Six databases and hand searches were used to identify eligible studies. Full HEE of workplace interventions targeting PA/SB were included. Methodological quality was assessed using the Consensus Health Economic Criteria (CHEC) list. Two researchers independently performed all procedures. Hedges' g was calculated to compare intervention effects. Outcomes from HEE were recalculated in 2017 euros and benefit-standardized. Results Eighteen HEE were identified that fulfilled on average 68% of the CHEC list criteria. Most studies showed improvements in PA/SB, but effects were small and thus, their relevance is questionable. Interventions were heterogeneous, no particular intervention type was found to be more effective. HEE were heterogeneous regarding methodological approaches and the selection of cost categories was inconsistent. Indirect costs were the main cost driver. In all studies, effects on costs were subject to substantial uncertainty. Conclusions Due to small effects and uncertain impact on costs, the economic evidence of worksite PA/SB-interventions remains unclear. Future studies are needed to determine effective strategies. The HEE of such interventions should be developed using guidelines and validated measures for productivity costs. Additionally, studies should model the long-term costs and effects because of the long pay-back time of PA/SB interventions.

Cost-effectiveness of mental health promotion and prevention for young people: a systematic review

Background

Effective mental health promotion and mental disorder prevention interventions may reduce the impact that mental health problems have on young people’s wellbeing. The objectives of this research were to summarize and assess health economic evaluations of mental health promotion and prevention for children and adolescents aged 6-18 years.

Methods

Four electronic databases were searched for full health economic evaluations published between January 1, 2013 and October 31, 2018 that evaluated the cost-effectiveness of universal mental health promotion and primary mental disorder prevention interventions. Each study was subject to a systematic quality-appraisal.

Results

Nine studies were included. Eight were carried out in the European Union, and eight evaluated school-based interventions. All evaluated interventions led to incremental costs compared to their comparators and most were associated with small increases in quality-adjusted life years. Four studies evaluated the cost-effectiveness of cognitive behavioural therapy-based interventions for the prevention of depression or anxiety, with mixed results. Cost-effectiveness estimates for mental health promotion and anti-bullying interventions were promising. Drivers of cost-effectiveness were implementation costs, intervention effectiveness, delivery mode and duration, baseline prevalence, and the perspective of the evaluation. The overall study quality was reasonable, though most studies only assessed short-term costs and effects.

Conclusions

Few studies were found. This limits the possibility of drawing strong conclusions about cost-effectiveness. There is some evidence based on decision-analytic modelling that anti-bullying interventions represent value for money. There is a lack of studies that take into account long-term costs and effects.

Key messages

Based on the evidence, schools should be supported in the implementation of long-term anti-bullying programmes to improve young people’s wellbeing. More research is needed on the long-term costs and effects of mental health promotion and prevention for children and adolescents.

A systematic review on costs and cost-effectiveness of screening and prevention of type 2 diabetes in women with prior gestational diabetes: Exploring uncharted territory

AIMS

Women with gestational diabetes mellitus (GDM) are more likely to develop type 2 diabetes mellitus (T2DM) as compared to women with normoglycemic pregnancies. This study aims to explore the literature on cost(-effectiveness) of screening and prevention of T2DM in women with prior GDM.

METHODS

Five databases were systematically searched, inclusion criteria were: (1) women with (prior) GDM; (2) post-partum screening or prevention of T2DM; and (3) health-economic evaluations. No year limits were applied. English, Dutch, French or German publications were included. Quality was assessed using the Consensus Health Economic Criteria checklist.

RESULTS

Two cost-effectiveness analyses and two cost analyses were found. One study evaluated nine screening strategies. Three studies evaluated one prevention strategy each: intensive diet and behavioural modification; annual counseling; and an annual dietary consultation. Methodological quality was poor. Perspectives were unclear, time horizons were too short, and no incremental analyses were performed.

CONCLUSION

An oral glucose tolerance test per three years leads to the lowest cost per case detected, and prevention is potentially cost-effective or cost-saving. More health economic evaluations are needed that compare all relevant alternatives, including 'doing nothing'.

Osteopathic care for spinal complaints: A systematic literature review

The aim of the current study was to evaluate the literature examining the impact of osteopathic care for spinal complaints. The bibliographic databases Medline (Pubmed), Web of Science, Embase, and PEDro were searched. In addition, a number of grey literature sources were searched. Only randomized controlled trials conducted in high-income Western countries were considered. Two authors independently screened the titles and abstracts. Primary outcomes included ‘pain’ and ‘functional status’, while secondary outcomes included ‘medication use’ and ‘health status’. It was examined if differences existed related to the treatment protocol and geography (European vs. US studies). Study quality was assessed using the risk of bias tool of the Cochrane Back Review Group. Nineteen studies were included and qualitatively synthesized. Nine studies were from the US, followed by Germany with seven studies. The majority of studies (n = 13) focused on low back pain. In general, mixed findings related to the impact of osteopathic care on primary and secondary outcomes were observed. For the primary outcomes, a clear distinction between US and European studies was found, in favor of the latter ones. Studies were characterized by substantial methodological differences in sample sizes, number of treatments, control groups, and follow-up. In conclusion, there is some evidence suggesting that osteopathic care may be effective for people suffering from spinal complaints. Further studies with larger study samples and assessment of long-term impact are required to further increase the evidence-based knowledge of the potential of osteopathic care for individuals suffering from spinal complaints.

Health-related costs in a sample of premenopausal non-diabetic overweight or obese females in Antwerp region: a cost-of-illness analysis

Background

People with overweight or obesity are at increased risk for disease later in life which cause important health costs.

The aim of this study was to estimate the health status and the corresponding costs in a sample of females with overweight or obesity which were participating in a Randomized Controlled Trial (RCT) exploring the effect of lifestyle habits changes on ectopic adipose tissue.

Methods

Sixty-two non-diabetic premenopausal females without major comorbidities of overweight and obesity were recruited among patients visiting endocrinologists at the obesity clinic of the University Hospital of Antwerp and the University of Antwerp.

A RCT-embedded cost-of-illness approach with societal perspective, based on self-reported questionnaires and cost diaries (3 months recall) was applied to estimate the prevalence of different comorbidities and the related direct and indirect costs in this sample of overweight or obese females. The European Quality-of-Life-5D questionnaire was used to define the health state and the corresponding utility index of the participants.

Results

The average direct health costs and health utilities observed in this sample were comparable with the general Flemish female population. This may partially be explained by the strict inclusion criteria of the RCT (i.e. overweight or obesity without diabetes type 2 or cardiovascular diseases). However, 15% of the participants had five or more comorbidities resulting in higher average costs and lower average health utility as compared to the general population, only 3 participants were diagnozed with the metabolic syndrome. In this subsample productivity was low due to high average absenteeism, yielding important total costs for the society.

Conclusion

Secondary prevention to avoid health deterioration in overweight or obese females without major comorbidies is needed to contain health care costs.

The health-related social costs of alcohol in Belgium

Background

Alcohol is associated with adverse health effects causing a considerable economic impact to society. A reliable estimate of this economic impact for Belgium is lacking. This is the aim of the study.

Methods

A prevalence-based approach estimating the direct, indirect and intangible costs for the year 2012 was used. Attributional fractions for a series of health effects were derived from literature. The human capital approach was used to estimate indirect costs, while the concept of disability-adjusted life years was used to estimate intangible costs. Sensitivity and scenario analyses were conducted to assess the uncertainty around cost estimates and to evaluate the impact of alternative modelling assumptions.

Results

In 2012, total alcohol-attributable direct costs were estimated at €906.1 million, of which the majority were due to hospitalization (€743.7 million, 82%). The indirect costs amounted to €642.6 million, of which 62% was caused by premature mortality. Alcohol was responsible for 157,500 disability-adjusted life years representing €6.3 billion intangible costs.

Conclusions

Despite a number of limitations intrinsic to this kind of research, the study can be considered as the most comprehensive analysis thus far of the health-related social costs of alcohol in Belgium.

A systematic review of health economic evaluation in adjuvant breast radiotherapy: Quality counted by numbers

BACKGROUND

Evolving practice in adjuvant breast radiotherapy inevitably impacts healthcare budgets. This is reflected in a rise of health economic evaluations (HEE) in this domain. The available HEE literature was analysed qualitatively and quantitatively, using available instruments.

METHODS

HEEs published between 1/1/2000 and 31/10/2016 were retrieved through a systematic search in Medline, Cochrane and Embase. A quality-assessment using CHEERS (Consolidated Health Economic Evaluation Reporting Standards) was translated into a quantitative score and compared with Tufts Medical Centre CEA registry and Quality of Health Economic Studies (QHES) results.

RESULTS

Twenty cost-effectiveness analyses (CEA) and thirteen cost comparisons (CC) were analysed. In qualitative evaluation, valuation or justification of data sources, population heterogeneity and discussion on generalizability, in addition to declaration on funding, were often absent or incomplete. After quantification, the average CHEERS-scores were 74% (CI 66.9-81.1%) and 75.6% (CI 70.7-80.5%) for CEAs and CCs respectively. CEA-scores did not differ significantly from Tufts and QHES-scores.

CONCLUSION

Quantitative CHEERS evaluation is feasible and yields comparable results to validated instruments. HEE in adjuvant breast radiotherapy is of acceptable quality, however, further efforts are needed to improve comprehensive reporting of all data, indispensable for assessing relevance, reliability and generalizability of results.

Within the triangle of healthcare legacies: comparing the performance of South-Eastern European health systems

OBJECTIVE

Inter-regional comparison of health-reform outcomes in south-eastern Europe (SEE).

METHODS

Macro-indicators were obtained from the WHO Health for All Database. Inter-regional comparison among post-Semashko, former Yugoslavia, and prior-1989-free-market SEE economies was conducted.

RESULTS

United Nations Development Program Human Development Index growth was strongest among prior-free-market SEE, followed by former Yugoslavia and post-Semashko. Policy cuts to hospital beds and nursing-staff capacities were highest in post-Semashko. Physician density increased the most in prior-free-market SEE. Length of hospital stay was reduced in most countries; frequency of outpatient visits and inpatient discharges doubled in prior-free-market SEE. Fertility rates fell for one third in Post-Semashko and prior-free-market SEE. Crude death rates slightly decreased in prior-free-market-SEE and post-Semashko, while growing in the former Yugoslavia region. Life expectancy increased by 4 years on average in all regions; prior-free-market SEE achieving the highest longevity. Childhood and maternal mortality rates decreased throughout SEE, while post-Semashko countries recorded the most progress.

CONCLUSIONS

Significant differences in healthcare resources and outcomes were observed among three historical health-policy legacies in south-eastern Europe. These different routes towards common goals created a golden opportunity for these economies to learn from each other.

Methodological Considerations in Social Cost Studies of Addictive Substances: A Systematic Literature Review

Background

Alcohol, tobacco, illicit drugs, and psychoactive pharmaceuticals’ use is associated with a higher likelihood of developing several diseases and injuries and, as a consequence, considerable health-care expenditures. There is yet a lack of consistent methodologies to estimate the economic impact of addictive substances to society. The aim was to assess the methodological approaches applied in social cost studies estimating the economic impact of alcohol, tobacco, illicit drugs, and psychoactive pharmaceuticals.

Methods

A systematic literature review through the electronic databases, Medline (PubMed) and Web of Science, was performed. Studies in English published from 1997 examining the social costs of the addictive substances alcohol, tobacco, illicit drugs, and psychoactive pharmaceuticals were eligible for inclusion.

Results

Twelve social cost studies met the inclusion criteria. In all studies, the direct and indirect costs were measured, but the intangible costs were seldom taken into account. A wide variety in cost items included across studies was observed. Sensitivity analyses to address the uncertainty around certain cost estimates were conducted in eight studies considered in the review.

Conclusion

Differences in cost items included in cost-of-illness studies limit the comparison across studies. It is clear that it is difficult to deal with all consequences of substance use in cost-of-illness studies. Future social cost studies should be based on sound methodological principles in order to result in more reliable cost estimates of the economic burden of substance use.

Economic Impact of Integrated Care Models for Patients with Chronic Diseases: A Systematic Review

OBJECTIVES

To assess the costs and potential financial benefits of integrated care models for patients with chronic diseases, that is, type 2 diabetes mellitus, schizophrenia, and multiple sclerosis, respectively.

METHODS

A systematic search of the literature was performed using EMBASE, MEDLINE, and Web of Science. Studies that conducted a cost analysis, considered at least two components of the chronic care model, and compared integrated care with standard care were included.

RESULTS

Out of 575 articles, 26 were included. Most studies examined integrated care models for type 2 diabetes mellitus (n = 18) and to a lesser extent for schizophrenia (n = 6) and multiple sclerosis (n = 2). Across the three disease groups, the incremental cost per patient per year ranged from - €3860 to + €613.91 (x¯ = - €533.61 ± €902.96). The incremental cost for type 2 diabetes mellitus ranged from - €1507.49 to + €299.20 (x¯ = - €518.22 ± + €604.75), for schizophrenia from - €3860 to + €613.91 (x¯ = - €677.21 ± + €1624.35), and for multiple sclerosis from - €822 to + €339.43 (x¯ = - €241.29 ± + €821.26). Most of the studies (22 of 26 [84.6%]) reported a positive economic impact of integrated care models: for type 2 diabetes mellitus (16 of 18 [88.9%]), schizophrenia (4 of 6 [66.7%]), and multiple sclerosis (1 of 2 [50%]).

CONCLUSIONS

In this systematic literature review, predominantly positive economic impacts of integrated care models for patients with chronic diseases were found.

Cost effectiveness of a pharmacist-led information technology intervention for reducing rates of clinically important errors in medicines management in general practices (PINCER)

BACKGROUND AND OBJECTIVE

We recently showed that a pharmacist-led information technology-based intervention (PINCER) was significantly more effective in reducing medication errors in general practices than providing simple feedback on errors, with cost per error avoided at £79 (US$131). We aimed to estimate cost effectiveness of the PINCER intervention by combining effectiveness in error reduction and intervention costs with the effect of the individual errors on patient outcomes and healthcare costs, to estimate the effect on costs and QALYs.

METHODS

We developed Markov models for each of six medication errors targeted by PINCER. Clinical event probability, treatment pathway, resource use and costs were extracted from literature and costing tariffs. A composite probabilistic model combined patient-level error models with practice-level error rates and intervention costs from the trial. Cost per extra QALY and cost-effectiveness acceptability curves were generated from the perspective of NHS England, with a 5-year time horizon.

RESULTS

The PINCER intervention generated £2,679 less cost and 0.81 more QALYs per practice [incremental cost-effectiveness ratio (ICER): -£3,037 per QALY] in the deterministic analysis. In the probabilistic analysis, PINCER generated 0.001 extra QALYs per practice compared with simple feedback, at £4.20 less per practice. Despite this extremely small set of differences in costs and outcomes, PINCER dominated simple feedback with a mean ICER of -£3,936 (standard error £2,970). At a ceiling 'willingness-to-pay' of £20,000/QALY, PINCER reaches 59 % probability of being cost effective.

CONCLUSIONS

PINCER produced marginal health gain at slightly reduced overall cost. Results are uncertain due to the poor quality of data to inform the effect of avoiding errors.

Direct medical costs of COPD diagnosis and treatment, Eastern vs Western European country – examples of Serbia and Belgium

OBJECTIVE: Comparison of COPD financial burden and underlying factors, between Eastern upper middle income and a Western European high income, healthcare settings.METHODS: The patient sample was 433 in Belgium and 322 in Serbia, age ≥ 40, with spirometry and clinically confirmed COPD diagnosis. Belgian trial followed patients prospectively during 2006, using structured survey of clinicians in charge. Serbian trial conducted in 2008, retrieved data from clinical invoice database. Time horizon was one year and perspective of third party payers was taken into account for both studies. Clinical outcomes of interest were disease exacerbation, hospital admission and death. Economic inputs referred to COPD-attributable medical services consumption value during observed period of time.RESULTS: Average annual cost was 1,812.84 € for the Serbian patients and 1,738.13 €/year for the Belgian patients (not including the value of laboratory diagnostics or imaging techniques). Severity grade and duration of hospital admissions significantly directly correlated with overall cost in both populations. Pattern of diagnostic procedures requested and ATC classes of drug consumed to treat COPD remains similar and comparable in both countries. GDP per capita ratio in respective years (10.4: 37.4), exhibits the paradox of patient being much less affordable to treat in a less developed society.CONCLUSIONS: Burden of COPD in Europe is huge and, due to contemporary life style expected to grow further. We compared cost of illness structures between two societies with different macroeconomic past in healthcare financing and management. According to our findings, direct medical costs were driven by exacerbations and hospital admissions. Significantly cheaper human labor caused higher relative relevance of drug acquisition expenses in the East and higher portion of hospital admission costs in the West. More in-depth research of indirect COPD attributable costs (e.g. lost productivity, absenteeism, premature death etc) will be needed in future. It implies serious health policy necessities to provide accessibility of care.

Health promotion in individuals with mental disorders: a cluster preference randomized controlled trial

Background

The existing literature on weight management interventions targeting physical activity and healthy eating in mental health care appears to provide only limited evidence. The aim of the study was to examine the effectiveness of a 10-week health promotion intervention, followed by a 6-month follow-up period in individuals with mental disorders living in sheltered housing in the Flanders region (Belgium).

Methods

The study had a cluster preference randomized controlled design. Twenty-five sheltered housing organisations agreed to participate (16 in the intervention group, nine in the control group). In the intervention group, 225 individuals agreed to participate, while in the control group 99 individuals entered into the study. The main outcomes were changes in body weight, Body Mass Index, waist circumference and fat mass. Secondary outcomes consisted of changes in physical activity levels, eating habits, health-related quality of life and psychiatric symptom severity.

Results

A significant difference was found between the intervention group and the control group regarding body weight (−0.35 vs. +0.22 kg; p=0.04), Body Mass Index (−0.12 vs. +0.08 kg/m²; p=0.04), waist circumference (−0.29 vs. + 0.55 cm; p<0.01), and fat mass (−0.99 vs. −0.12%; p<0.01). The decrease in these outcomes in the intervention group disappeared during the follow up period, except for fat mass. Within the intervention group, a larger decrease in the primary outcomes was found in the participants who completed the intervention. No significant differences between the two groups in changes in the secondary outcomes were found, except for the pedometer-determined steps/day. In the intervention group, the mean number of daily steps increased, while it decreased in the control group.

Conclusions

The study demonstrated that small significant improvements in the primary outcomes are possible in individuals with mental disorders. Integration of health promotion activities targeting physical activity and healthy eating into daily care are, however, necessary to maintain the promising results.

Determinants of nonurgent use of the emergency department for pediatric patients in 12 hospitals in Belgium

INTRODUCTION

The nonurgent use of the emergency department (ED) for pediatric patients is an increasing problem facing healthcare systems worldwide. To evaluate the magnitude of the phenomenon and to identify associated factors, an observational prospective survey was performed including all patients (<15 years) attending the ED in 12 Belgian hospitals during 2 weeks in autumn 2010. Use of ED was considered appropriate if at least one of the following criteria was met: child referred by doctor or police, brought by ambulance, in need for short stay, technical examination or orthopedic treatment, in-patient admission, or death. Among the 3,117 children, attending ED, 39.9 % (1,244) of visits were considered inappropriate. Five factors were significantly associated with inappropriate use: age of child, distance to ED, having a registered family doctor, out-of-hours visit, and geographic region. The adjusted odds ratio and 95 % confidence intervals are respectively-1.7 (1.3-2.0), 1.7 (1.3-2.2), 1.5 (1.1-2.2), 1.5 (1.2-1.9), and 0.6 (0.5-0.8).

CONCLUSIONS

Almost 40 % of all paediatric ED attendances did not require hospital expertise. The risk of an inappropriate use of ED by pediatrician patients is predominantly associated with organizational and cultural factors. Access, equity, quality of care, and medical human resources availability have to be taken into account to design financially sustainable model of care for those patients. Furthermore, future research is needed to explain reasons why parents visit ED rather than using of primary-care services.

Health promotion intervention in mental health care: design and baseline findings of a cluster preference randomized controlled trial

BACKGROUND

Growing attention is given to the effects of health promotion programs targeting physical activity and healthy eating in individuals with mental disorders. The design of evaluation studies of public health interventions poses several problems and the current literature appears to provide only limited evidence on the effectiveness of such programs. The aim of the study is to examine the effectiveness and cost-effectiveness of a health promotion intervention targeting physical activity and healthy eating in individuals with mental disorders living in sheltered housing. In this paper, the design of the study and baseline findings are described.

METHODS/DESIGN

The design consists of a cluster preference randomized controlled trial. All sheltered housing organisations in the Flanders region (Belgium) were asked if they were interested to participate in the study and if they were having a preference to serve as intervention or control group. Those without a preference were randomly assigned to the intervention or control group. Individuals in the intervention group receive a 10-week health promotion intervention above their treatment as usual. Outcome assessments occur at baseline, at 10 and at 36 weeks. The primary outcomes include body weight, Body Mass Index, waist circumference, and fat mass. Secondary outcomes consist of physical activity levels, eating habits, health-related quality of life and psychiatric symptom severity. Cost-effectiveness of the intervention will be examined by calculating the Cost-Effectiveness ratio and through economic modeling.Twenty-five sheltered housing organisations agreed to participate. On the individual level 324 patients were willing to participate, including 225 individuals in the intervention group and 99 individuals in the control group. At baseline, no statistical significant differences between the two groups were found for the primary outcome variables.

DISCUSSION

This is the first trial evaluating both the effectiveness and cost-effectiveness of a health promotion intervention targeting physical activity and healthy eating in mental health care using a cluster preference randomized controlled design. The baseline characteristics already demonstrate the unhealthy condition of the study population.

This study is registered at clinicaltrials.gov - NCT 01336946.

Perceptions of mental health nurses and patients about health promotion in mental health care: a literature review

The aim of this review was to examine the perceptions of patients with mental disorders and mental health nurses of health promotion targeting physical activity and eating habits in mental health care. An electronic search strategy was conducted. Furthermore, references were searched by hand-searching the reference lists of the retrieved articles from the electronic databases. The literature on perceptions of health promotion and lifestyle interventions in mental health care principally consist of qualitative studies using interviews and focus groups. Positive perceptions of both mental health nurses and patients towards health promotion targeting physical activity and eating habits in mental health care were identified. Contrary, several barriers for integrating healthy lifestyles into the daily life of patients were described. Patients usually want to learn more about healthy lifestyles, but see the ability to change their physical health as beyond their control. In this sense, support from mental health nurses is considered as important. Despite the awareness of the importance of health promotion in mental health care, it appears that visions and attitudes towards the potential of health promotion are in need of change.

Effectiveness and cost-effectiveness of lifestyle interventions on physical activity and eating habits in persons with severe mental disorders: a systematic review

BACKGROUND

There is a high prevalence of overweight and obesity in persons with severe mental disorders and this has serious implications on the short and long term health outcomes of these patients. The aim of this review was to evaluate the effectiveness of lifestyle interventions targeting physical activity and eating habits in persons with severe mental disorders. Special attention was given if any of the included studies in the review also examined the cost-effectiveness of these health promotion interventions.

METHODS

A systematic search through the electronic databases Medline, Web of Science, CINAHL and Cohrane Library was conducted, and by hand-searching the reference lists of the retrieved articles from the electronic databases. Studies were included if they examined effectiveness and/or cost-effectiveness of lifestyle interventions targeting physical activity and eating habits in persons with severe mental disorders, with primary outcome changes in Body Mass Index and body weight.

RESULTS

Fourteen studies met the inclusion criteria. Weight loss and Body Mass Index decrease were observed in intervention groups in 11 studies. The difference in weight change between intervention and control groups was statistically significant in nine studies. Differences in mean Body Mass Index between intervention and control groups were statistically significant in eight studies. Five studies reported improvements in quality of life and general health. In none of the studies cost-effectiveness of lifestyle interventions was examined.

CONCLUSION

Further research on both effectiveness and cost-effectiveness of lifestyle interventions targeting physical activity and eating habits in persons with severe mental disorders is required to assist in the development of new health promotion interventions in this population.

HOPE, an open platform for medical data management on the grid

The paper describes a platform developed for the secure management and analysis of medical data and images in a grid environment. Designed for telemedicine and built upon the EGEE gLite middleware and particularly the metadata catalogue AMGA as well as the GridSphere web portal, the platform provides to healthcare professionals the capacity to upload and query medical information stored over distributed servers. A job submission environment is also available for data analysis. Security features include authentication and authorization by grid certificates, anonymization of medical data and image encryption. The platform is currently deployed on several sites in Europe and Asia and is being customized for applications in the field of telemedicine and medical physics.
