Social Risk and Dialysis Facility Performance in the First Year of the ESRD Treatment Choices Model.

Importance: The End-Stage Renal Disease Treatment Choices (ETC) model randomly selected 30% of US dialysis facilities to receive financial incentives based on their use of home dialysis, kidney transplant waitlisting, or transplant receipt. Facilities that disproportionately serve populations with high social risk have a lower use of home dialysis and kidney transplant raising concerns that these sites may fare poorly in the payment model. Objective: To examine first-year ETC model performance scores and financial penalties across dialysis facilities, stratified by their incident patients' social risk. Design, Setting, and Participants: A cross-sectional study of 2191 US dialysis facilities that participated in the ETC model from January 1 through December 31, 2021. Exposure: Composition of incident patient population, characterized by the proportion of patients who were non-Hispanic Black, Hispanic, living in a highly disadvantaged neighborhood, uninsured, or covered by Medicaid at dialysis initiation. A facility-level composite social risk score assessed whether each facility was in the highest quintile of having 0, 1, or at least 2 of these characteristics. Main Outcomes and Measures: Use of home dialysis, waitlisting, or transplant; model performance score; and financial penalization. Results: Using data from 125 984 incident patients (median age, 65 years [IQR, 54-74]; 41.8% female; 28.6% Black; 11.7% Hispanic), 1071 dialysis facilities (48.9%) had no social risk features, and 491 (22.4%) had 2 or more. In the first year of the ETC model, compared with those with no social risk features, dialysis facilities with 2 or more had lower mean performance scores (3.4 vs 3.6, P = .002) and lower use of home dialysis (14.1% vs 16.0%, P < .001). These facilities had higher receipt of financial penalties (18.5% vs 11.5%, P < .001), more frequently had the highest payment cut of 5% (2.4% vs 0.7%; P = .003), and were less likely to achieve the highest bonus of 4% (0% vs 2.7%; P < .001). Compared with all other facilities, those in the highest quintile of treating uninsured patients or those covered by Medicaid experienced more financial penalties (17.4% vs 12.9%, P = .01) as did those in the highest quintile in the proportion of patients who were Black (18.5% vs 12.6%, P = .001). Conclusions: In the first year of the Centers for Medicare & Medicaid Services' ETC model, dialysis facilities serving higher proportions of patients with social risk features had lower performance scores and experienced markedly higher receipt of financial penalties.

Return on investment of self-measured blood pressure is associated with its use in preventing false diagnoses, not monitoring hypertension.

Previous research indicates that patient self-measured blood pressure (SMBP) is a cost-effective strategy for improving hypertension (HTN) diagnosis and control. However, it is unknown which specific uses of SMBP produce the most value. Our goal is to estimate, from an insurance perspective, the return-on-investment (ROI) and net present value associated with coverage of SMBP devices when used (a) only to diagnose HTN, (b) only to select and titrate medication, (c) only to monitor HTN treatment, or (d) as a bundle with all three uses combined. We employed national sample of claims data, Framingham risk predictions, and published sensitivity-specificity values of SMBP and clinic blood-pressure measurement to extend a previously-developed local decision-analytic simulation model. We then used the extended model to determine which uses of SMBP produce the most economic value when scaled to the U.S. adult population. We found that coverage of SMBP devices yielded positive ROIs for insurers in the short-run and at lifetime horizon when the three uses of SMBP were considered together. When each use was evaluated separately, positive returns were seen when SMBP was used for diagnosis or for medication selection and titration. However, returns were negative when SMBP was used exclusively to monitor HTN treatment. When scaled to the U.S. population, adoption of SMBP would prevent nearly 16.5 million false positive HTN diagnoses, thereby improving quality of care while saving insurance plans $254 per member. A strong economic case exists for insurers to cover the cost of SMBP devices, but it matters how devices are used.

Self-management interventions for adults living with Chronic Obstructive Pulmonary Disease (COPD): The development of a Core Outcome Set for COMPAR-EU project.

BACKGROUND: A large body of evidence suggests that self-management interventions (SMIs) may improve outcomes in chronic obstructive pulmonary disease (COPD). However, accurate comparisons of the relative effectiveness of SMIs are challenging, partly due to heterogeneity of outcomes across trials and uncertainty about the importance of these outcomes for patients. We aimed to develop a core set of patient-relevant outcomes (COS) for SMIs trials to enhance comparability of interventions and ensure person-centred care. METHODS: We undertook an innovative approach consisting of four interlinked stages: i) Development of an initial catalogue of outcomes from previous EU-funded projects and/or published studies, ii) Scoping review of reviews on patients and caregivers' perspectives to identify outcomes of interest, iii) Two-round Delphi online survey with patients and patient representatives to rate the importance of outcomes, and iv) Face-to-face consensus workshop with patients, patient representatives, health professionals and researchers to develop the COS. RESULTS: From an initial list of 79 potential outcomes, 16 were included in the COS plus one supplementary outcome relevant to all participants. These were related to patient and caregiver knowledge/competence, self-efficacy, patient activation, self-monitoring, adherence, smoking cessation, COPD symptoms, physical activity, sleep quality, caregiver quality of life, activities of daily living, coping with the disease, participation and decision-making, emergency room visits/admissions and cost effectiveness. CONCLUSION: The development of the COPD COS for the evaluation of SMIs will increase consistency in the measurement and reporting of outcomes across trials. It will also contribute to more personalized health care and more informed health decisions in clinical practice as patients' preferences regarding COPD outcomes are more systematically included.

Telemedicine in the OECD: An umbrella review of clinical and cost-effectiveness, patient experience and implementation.

INTRODUCTION: Patients and policy makers alike have high expectations for the use of digital technologies as tools to improve health care service quality at a sustainable cost. Many countries within the Organisation for Economic Co-operation and Development (OECD) are investing in telemedicine initiatives, and a large and growing body of peer-reviewed studies on the topic has developed, as a consequence. Nonetheless, telemedicine is still not used at scale within the OECD. Seeking to provide a snapshot of the evidence on the use of telemedicine in the OECD, this umbrella review of systematic reviews summarizes findings on four areas of policy relevance: clinical and cost-effectiveness, patient experience, and implementation. METHODS: This review followed a prior written, unregistered protocol. Four databases (PubMed/Medline, CRD, and Cochrane Library) were searched for systematic reviews or meta-analyses published between January 2014 and February 2019. Based on the inclusion criteria, 98 systematic reviews were selected for analysis. Due to substantial heterogeneity, a meta-analysis was not conducted. The quality of included reviews was assessed using the AMSTAR 2 tool. RESULTS: Most reviews (n = 53) focused on effectiveness, followed by cost-effectiveness (n = 18), implementation (n = 17) and patient experience (n = 15). Eighty-three percent of clinical effectiveness reviews found telemedicine at least as effective as face-to-face care, and thirty-nine percent of cost-effectivenss reviews found telemedicine to be cost saving or cost-effective. Patients reported high acceptance of telemedicine and the most common barriers to implementation were usability and lack of reimbursement. However, the methodological quality of most reviews was low to critically low which limits generalizability and applicability of findings. CONCLUSION: This umbrella review finds that telemedicine interventions can improve glycemic control in diabetic patients; reduce mortality and hospitalization due to chronic heart failure; help patients manage pain and increase their physical activity; improve mental health, diet quality and nutrition; and reduce exacerbations associated with respiratory diseases like asthma. In certain disease and specialty areas, telemedicine may be a less effective way to deliver care. While there is evidence that telemedicine can be cost-effective, generalizability is hindered by poor quality and reporting standards. This umbrella review also finds that patients report high levels of acceptance and satisfaction with telemedicine interventions, but that important barriers to wider use remain.

Long-term Cost-Effectiveness of Dexcom G6 Real-time Continuous Glucose Monitoring Versus Self-Monitoring of Blood Glucose in Patients With Type 1 Diabetes in the U.K.

OBJECTIVE: A long-term health economic analysis was performed to establish the cost-effectiveness of real-time continuous glucose monitoring (RT-CGM) (Dexcom G6) versus self-monitoring of blood glucose (SMBG) alone in U.K.-based patients with type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS: The analysis used the IQVIA CORE Diabetes Model. Clinical input data were sourced from the DIAMOND trial in adults with T1D. Simulations were performed separately in the overall population of patients with baseline HbA1c ≥7.5% (58 mmol/mol), and a secondary analysis was performed in patients with baseline HbA1c ≥8.5% (69 mmol/mol). The analysis was performed from the National Health Service health care payer perspective over a lifetime time horizon. RESULTS: In the overall population, G6 RT-CGM was associated with a mean incremental gain in quality-adjusted life expectancy of 1.49 quality-adjusted life years (QALYs) versus SMBG (mean [SD] 11.47 [2.04] QALYs versus 9.99 [1.84] QALYs). Total mean (SD) lifetime costs were also pounds sterling (GBP) 14,234 higher with RT-CGM (GBP 102,468 [35,681] versus GBP 88,234 [39,027]) resulting in an incremental cost-effectiveness ratio of GBP 9,558 per QALY gained. Sensitivity analyses revealed that the findings were sensitive to changes in the quality-of-life benefit associated with reduced fear of hypoglycemia and avoidance of fingerstick testing as well as the HbA1c benefit associated with RT-CGM use. CONCLUSIONS: For U.K.-based T1D patients, the G6 RT-CGM device is associated with significant improvements in clinical outcomes and, over patient lifetimes, is a cost-effective disease management option relative to SMBG on the basis of a willingness-to-pay threshold of GBP 20,000 per QALY gained.

Cost-effectiveness analysis of repeated self-sampling for HPV testing in primary cervical screening: a randomized study.

BACKGROUND: Human papillomavirus (HPV) testing is recommended in primary cervical screening to improve cancer prevention. An advantage of HPV testing is that it can be performed on self-samples, which could increase population coverage and result in a more efficient strategy to identify women at risk of developing cervical cancer. Our objective was to assess whether repeated self-sampling for HPV testing is cost-effective in comparison with Pap smear cytology for detection of cervical intraepithelial neoplasia grade 2 or more (CIN2+) in increasing participation rate in primary cervical screening. METHODS: A cost-effectiveness analysis (CEA) was performed on data from a previously published randomized clinical study including 36,390 women aged 30-49 years. Participants were randomized either to perform repeated self-sampling of vaginal fluid for HPV testing (n = 17,997, HPV self-sampling arm) or to midwife-collected Pap smears for cytological analysis (n = 18,393, Pap smear arm). RESULTS: Self-sampling for HPV testing led to 1633 more screened women and 107 more histologically diagnosed CIN2+ at a lower cost vs. midwife-collected Pap smears (€ 229,446 vs. € 782,772). CONCLUSIONS: This study resulted in that repeated self-sampling for HPV testing increased participation and detection of CIN2+ at a lower cost than midwife-collected Pap smears in primary cervical screening. Offering women a home-based self-sampling may therefore be a more cost-effective alternative than clinic-based screening. TRIAL REGISTRATION: Not registered since this trial is a secondary analysis of an earlier published study (Gustavsson et al., British journal of cancer. 118:896-904, 2018).

Impact of Behavioral Health Homes on Cost and Utilization Outcomes.

OBJECTIVE: This study evaluated the impact of two behavioral health home (BHH) approaches, provider-supported care and self-directed care, on health care utilization and cost outcomes among adult Medicaid recipients with serious mental illness. METHODS: Eleven community mental health provider sites were randomly assigned to one of the BHH approaches, which each site implemented over a 2-year period. In both approaches, staff were trained in wellness coaching to support patients' progress toward general health and wellness goals. Provider-supported sites employed a full-time on-site registered nurse, who provided consultation to patients and wellness coaches. Each approach had a consistently enrolled treatment group (combined N=859) with a matched comparison cohort that was identified for analysis. Approaches were compared with each other and with baseline, and differences between each approach and its comparison cohort were examined by using analysis of covariance to determine impact on total health care cost, prescription costs, and use and cost of general medical and behavioral health services. RESULTS: Relative to its comparison cohort, each approach achieved significant reductions in total cost (15% for provider-supported care and 26% for self-directed care) and increases in use of outpatient general medical services (43% for provider-supported care and 29% for self-directed care). Compared with self-directed care, provider-supported care resulted in approximately 28% lower use of general medical inpatient services and 26% lower related costs. CONCLUSIONS: BHH approaches in community mental health settings can produce health care savings and decrease use of inpatient health care.

A French Value Set for the EQ-5D-5L.

OBJECTIVE: The objective of this study was to develop a French value set for the EQ-5D-5L, for academic and clinical research, and for regulatory requirements for price-setting of drugs and medical devices. METHOD: This study used the standardized valuation protocol developed by EuroQol, using computer-assisted personal interview software. A representative sample of 1048 French residents were interviewed by a market research company, under the supervision of the research team. Health states were valued using composite time trade-off and a discrete choice experiment. Modeling was used to create values for the 3125 possible health states. The composite time trade-off data were modeled using a Tobit model with censored observations at -1 and correcting for heteroscedasticity. A conditional logit model was used for the discrete choice results, and both models were combined using a hybrid model. An adjusted hybrid model was tested to correct for imbalance in the sample on age and sex compared with the general population. A comparison with the 3-level (3L) value set was performed. RESULTS: The adjusted model was preferred to comply with the representativeness of the general population. It provided a value set for which all coefficients were logically consistent. Values ranged from - 0.525 to 1. The distribution of values presented a shift towards higher values versus the 3L value set. Ranking of dimensions changed. Pain and discomfort and mobility were the dimensions with the highest potential for disutility compared with mobility and self-care for the 3L instrument. CONCLUSIONS: This study provides a value set based on societal preferences of the French population, using an improved descriptive instrument of health-related quality-of-life health states. It will contribute to improve the quality of cost-effectiveness analysis in the French context and help stimulate disease-specific quality-of-life references for academic-, institutional-, and industry-promoted studies.

Home-based pulmonary rehabilitation for COPD using minimal resources: An economic analysis.

BACKGROUND AND OBJECTIVE: This study aimed to compare the cost-effectiveness and cost-utility of home and centre-based pulmonary rehabilitation for adults with stable chronic obstructive pulmonary disease (COPD). METHODS: Prospective economic analyses were undertaken from a health system perspective alongside a randomized controlled equivalence trial in which participants referred to pulmonary rehabilitation undertook a standard 8-week outpatient centre-based or a new home-based programme. Participants underwent clinical assessment prior to programme commencement, immediately following completion and 12 months following programme completion. They provided data for utility (quality-adjusted life years (QALY) determined using SF6D (utility scores for health states) calculated from 36-Item Short Form Health Survey version 2) and effectiveness (change in distance walked on 6-min walk test (Δ6MWD) following pulmonary rehabilitation ). Individual-level cost data for the 12 months following programme completion was sourced from healthcare administration and government databases. RESULTS: Between-group mean difference point estimates for cost (-$4497 (95% CI: -$12 250 to $3257), utility (0.025 (-0.038 to 0.086) QALY) and effectiveness (14 m (-11 to 39) Δ6MWD) favoured the home-based group. Cost-utility analyses demonstrated 63% of estimates falling in the dominant southeast quadrant and the probability that the new home-based model was cost-effective at a $0 threshold for willingness to pay was 78%. Results were robust to a range of sensitivity analyses. Programme completion was associated with significantly lower healthcare costs in the following 12 months. CONCLUSION: Home-based pulmonary rehabilitation provides a cost-effective alternative model for people with COPD who cannot access traditional centre-based programmes.

An exploratory parallel-group randomised controlled trial of antenatal Guided Self-Help (plus usual care) versus usual care alone for pregnant women with depression: DAWN trial.

BACKGROUND: Depression is a common antenatal mental disorder associated with significant maternal morbidity and adverse fetal outcomes. However, there is a lack of research on the effectiveness or cost-effectiveness of psychological interventions for antenatal depression. METHODS: A parallel-group, exploratory randomised controlled trial across five hospitals. The trial compared Guided Self-Help, modified for pregnancy, plus usual care with usual care alone for pregnant women meeting DSM-IV criteria for mild-moderate depression. The trial objectives were to establish recruitment/follow-up rates, compliance and acceptability, and to provide preliminary evidence of intervention efficacy and cost-effectiveness. The primary outcome of depressive symptoms was assessed by blinded researchers using the Edinburgh Postnatal Depression Scale at 14-weeks post-randomisation. RESULTS: 620 women were screened, 114 women were eligible and 53 (46.5%) were randomised. 26 women received Guided Self-Help - 18 (69%) attending ≥4 sessions - and 27 usual care; n = 3 women were lost to follow-up (follow-up rate for primary outcome 92%). Women receiving Guided Self-Help reported fewer depressive symptoms at follow-up than women receiving usual care (adjusted effect size -0.64 (95%CI: -1.30, 0.06) p = 0.07). There were no trial-related adverse events. The cost-effectiveness acceptability curve showed the probability of Guided Self-Help being cost-effective compared with usual care ranged from 10 to 50% with a willingness-to-pay range from £0 to £50,000. CONCLUSIONS AND LIMITATIONS: Despite intense efforts we did not meet our anticipated recruitment target. However, high levels of acceptability, a lack of adverse events and a trend towards improvements in symptoms of depression post-treatment indicates this intervention is suitable for talking therapy services.

Patient Use of Cardiovascular Devices and Apps: Are We Getting Our Money's Worth?

The evolution of technology makes it likely that a large number of people will invest in and use health-related mobile applications and wearable devices. Yet the question remains: Do these technology-based interventions modify health behavior and improve health…and are we getting our money's worth? The vast majority of studies concerning health-related apps and wearable devices have small sample sizes and short time spans of 6 months or less, so it is not clear if these durations were determined by lack of consistent use over time. Furthermore, many of the most popular applications have not been subjected to randomized trials. Overall, the small demonstrated improvements in outcomes are often associated with professional involvement from clinicians, coaches, or diabetes educators provided in conjunction with use of mobile health (mHealth) platforms. This paper explores the use of mHealth technologies that address cardiovascular disease/prevention (eg, diabetes, diet, physical activity, and associated weight loss) and discusses the lack of adequate evidence to support even minimal patient investment in mobile applications or wearable devices at this time.

Adolescent and parent perspectives on the acceptability of financial incentives to promote self-care in adolescents with type 1 diabetes.

BACKGROUND: An understanding of acceptability among potential intervention participants is critical to the design of successful real-world financial incentive (FI) programs. The purpose of this qualitative study was to explore adolescent and parent perspectives on the acceptability of using FI to promote engagement in diabetes self-care in adolescents with type 1 diabetes (T1D). METHODS: Focus groups with 46 adolescents with T1D (12-17 years old) and 39 parents of adolescents with T1D were conducted in the Seattle metropolitan area. Semistructured questions addressed participants' current use of incentives to promote change in diabetes self-care and receptivity to a theoretical incentive program administered by a third-party. Qualitative data were analyzed and emergent themes identified. RESULTS: Three thematic categories informed participant views about the acceptability of FI programs: (a) the extent to which using FIs in the context of diabetes management fit comfortably into a family's value system, (b) the perceived effectiveness for FIs to promote improved diabetes self-care, and (c) the urgent need for improved self-care due to the threat of diabetes-related health complications. These factors together led most parents and adolescents to be open to FI program participation. CONCLUSIONS: The results from this qualitative study suggest that well-designed FI programs to support diabetes management are acceptable to families with adolescents with T1D. Additionally, the use of FIs may have the potential to support adolescents with T1D in developing strong self-care habits and ease the often-turbulent transition to independent self-care.

Promoting Independence in Dementia (PRIDE): protocol for a feasibility randomised controlled trial.

BACKGROUND: Memory services often see people with early stage dementia who are largely independent and able to participate in community activities but who run the risk of reducing activities and social networks. PRIDE is a self-management intervention designed to promote living well and enhance independence for people with mild dementia. This study aims to examine the feasibility of conducting a definitive randomised trial comparing the clinical and cost-effectiveness of the PRIDE intervention offered in addition to usual care or with usual care alone. METHODS/DESIGN: PRIDE is a parallel, two-arm, multicentre, feasibility, randomised controlled trial (RCT). Eligible participants aged 18 or over who have mild dementia (defined as a score of 0.5 or 1 on the Clinical Dementia Rating Scale) who can participate in the intervention and provide informed consent will be randomised (1:1) to treatment with the PRIDE intervention delivered in addition to usual care, or usual care only. Participants will be followed-up at 3 and 6 month's post-randomisation. There will be an option for a supporter to join each participant. Each supporter will be provided with questionnaires at baseline and follow-ups at 3 to 6 months. Embedded qualitative research with both participants and supporters will explore their perspectives on the intervention investigating a range of themes including acceptability and barriers and facilitators to delivery and participation. The feasibility of conducting a full RCT associated with participant recruitment and follow-up of both conditions, intervention delivery including the recruitment, training, retention of PRIDE trained facilitators, clinical outcomes, intervention and resource use costs and the acceptability of the intervention and study related procedures will be examined. DISCUSSION: This study will assess whether a definitive randomised trial comparing the clinical and cost-effectiveness of whether the PRIDE intervention offered in addition to usual care is feasible in comparison to usual care alone, and if so, will provide data to inform the design and conduct of a future trial.

The (cost) effectiveness of guided internet-based self-help CBT for dialysis patients with symptoms of depression: study protocol of a randomised controlled trial.

BACKGROUND: Only a minority of dialysis patients with depressive symptoms are diagnosed and receive treatment. Depressive symptoms are highly prevalent in this population and are associated with adverse clinical outcomes. Underlying factors for this undertreatment may be the lack of evidence for the safety and effectivity of antidepressant medication, the reluctance of patients to adhere to antidepressant medication, the lack of mental healthcare provision in somatic healthcare environments and end-stage renal disease (ESRD) related physical limitations that complicate face-to-face psychotherapy. Guided Internet-based self-help treatment has demonstrated to be effective for depressive symptoms in other chronic patient populations and may overcome these barriers. The aim of this study is to investigate the (cost) effectiveness of a guided Internet-based self-help intervention for symptoms of depression in dialysis patients. METHODS: This study is a cluster randomized controlled trial (RCT) that investigates the effectiveness of a 5-week Internet-based self-help Problem Solving Therapy (PST) for depressive symptoms in dialysis patients. Depressive symptoms will be measured using the Beck Depression Inventory - second edition (BDI-II), with a cut-off score of ≥10. We aim to include 206 dialysis patients with depressive symptoms who will be cluster randomized to the intervention or the Care as Usual (CAU) control group. Secondary outcomes will include anxiety symptoms, quality of life, economic costs and clinical outcomes, such as inflammatory factors and hair cortisol levels. Assessments will take place at baseline (T0), 2 weeks after intervention (T1) and 6 months (T2), 12 months (T3) and 18 months (T4) after intervention. The control group will be measured at the same time points. Analysis will be based on the intention-to-treat principle. Mixed models will be used to assess the changes within each condition between pre-treatment and post-treatment. DISCUSSION: If demonstrated to be (cost) effective, Internet-based PST will offer new possibilities to treat dialysis patients with depressive symptoms and to improve their quality of care.

Economic costs of implementing group interventions to reduce diabetes distress in adults with type 1 diabetes mellitus in the T1-REDEEM trial.

AIMS: This study evaluated the implementation costs of two group interventions, one focused on diabetes education (KnowIt) and one focused directly on diabetes distress (OnTrack), that reduced diabetes distress and HbA1C in adults with poorly controlled type 1 diabetes (T1DM) in the T1-REDEEM trial. METHODS: Resources used to provide interventions were enumerated using activity-based micro-costing methods. Costs were assigned to resources in 2017 US dollars. US median wage and benefit rates were used to calculate costs of staff time. Cost per unit change was calculated for diabetes distress and HbA1C. RESULTS: For both interventions, per participant implementation costs were approximately $250 and cost per 1.0 percentage point (11 mmol/mol) change in HbA1C was $1400. Cost per unit change in diabetes distress was $364 for KnowIt and $335 for OnTrack. No statistically significant differences in costs were observed. CONCLUSIONS: This is the first study to examine the costs of implementing interventions targeting diabetes distress in the context of T1DM. Both interventions had per participant implementation costs in the lower end of the range of previously examined diabetes self-management interventions ($219 to $5390). These inventions and their costs merit further attention because reducing diabetes distress may impact long term T1DM outcomes. CLINICAL TRIALS REGISTRATION: ClinicalTrials.govNCT02175732.

The cost-effectiveness of stepped care for the treatment of anxiety disorders in adults: A model-based economic analysis for the Australian setting.

OBJECTIVE: To evaluate the cost-effectiveness of stepped care compared to care as usual (CAU) for the treatment of adults with mild-to-moderate anxiety disorders from a health sector perspective in the Australian setting. METHOD: A decision tree model was constructed to estimate the cost per disability adjusted life year (DALY) averted over a 12-month time horizon. The model compared a three-step stepped care intervention to CAU. Stepped care included an initial phase of guided self-help, followed by face-to-face cognitive behavioural therapy, and pharmacotherapy as the final step. The model adopted a health sector perspective, used epidemiological parameters and disability weights obtained from the Global Burden of Disease Study 2013. Effect sizes were derived from a randomized trial of stepped care and a longitudinal cohort study. Costs were expressed in 2013 Australian dollars (A$). Multivariate probabilistic and univariate sensitivity analyses were performed. RESULTS: Stepped care was found to be cost-effective compared to CAU with an incremental cost-effective ratio of A$3093 per DALY averted. One-hundred percent of the uncertainty iterations fell below the A$50,000 per DALY averted willingness-to-pay threshold commonly used in Australia. The evaluation was most sensitive to changes in diagnosis rates and effect sizes. CONCLUSION: A three-step model of stepped care appears to be cost-effective for the treatment of adults with mild to moderate anxiety disorders from the Australian health sector perspective. These results can provide some assurance to decision-makers that stepped care represents an efficient use of health care resources.

Supported self-help to prevent relapse or recurrence of depression: Who benefits most?

BACKGROUND: This study aimed to identify subgroups for whom supported self-help preventive cognitive therapy (S-PCT) is more (cost)effective than treatment as usual (TAU) in preventing relapse and recurrence of major depression. METHODS: We conducted a randomized controlled trial in which 248 remitted, recurrently depressed participants were randomized to S-PCT (n = 124) or TAU (n = 124). Clinical outcome was relapse or recurrence of major depressive disorder (SCID-I). We tested the moderating effects on relapse or recurrence of age, gender, education level, residual depressive symptoms, number of previous episodes, age of onset, antidepressant medication, somatization, and self-efficacy with logistic regression analyses adjusted for baseline values of depressive symptoms. We examined moderating effects on costs using linear regression analyses adjusted for baseline costs. A stratified cost-effectiveness analysis was performed to tease out differences in cost-effectiveness between subgroups. RESULTS: We found no moderating effect on relapse or recurrence for any of the potential moderators. For costs, the number of previous depressive episodes was identified as a moderator. At a willingness-to-pay of 16,000€, the probability that S-PCT was cost-effective compared to TAU was 95% for participants with 2-3 episodes and 11% for participants with ≥4 episodes. LIMITATIONS: Participants and counselors were not blinded. The study was primarily designed to assess the (cost)effectiveness of S-PCT and not to conduct moderation analyses. CONCLUSIONS: S-PCT was effective in preventing relapse or recurrence of depressive disorders in a broad range of participants, but is more likely to be cost-effective in participants with 2-3 episodes than ≥4 episodes. This indicates that S-PCT can best be offered to participants with fewer previous depressive episodes.

The Prevalence and Characteristics of Untreated Hernias in Southwest Cameroon.

BACKGROUND: Hernias are one of the most commonly encountered surgical conditions, and every year, more than 20 million hernia repairs are performed worldwide. The surgical management of hernia, however, is largely neglected as a public health priority in developing countries, despite its cost-effectiveness. To date, the prevalence and impact of hernia have not been formally studied in a community setting in Cameroon. The aim of this study was to determine the prevalence and characteristics of untreated hernia in the Southwest region of Cameroon. METHODS: This study was a subanalysis of a cross-sectional community-based survey on injury in Southwest Cameroon. Households were sampled using a three-stage cluster sampling method. Household representatives reported all untreated hernias occurring in the past year. Data on socioeconomic factors, hernia symptoms, including the presence of hernia incarceration, and treatment attempts were collected between January 2017 and March 2017. RESULTS: Among 8065 participants, 73 persons reported symptoms of untreated hernia, resulting in an overall prevalence of 7.4 cases per 1000 persons (95% confidence limit 4.98-11.11). Groin hernias were most commonly reported (n = 49, 67.1%) and predominant in young adult males. More than half of persons with untreated hernia (56.7%) reported having symptoms of incarceration, yet 42.1% (n = 16) of these participants did not receive any surgical treatment. Moreover, 21.9% of participants with untreated hernias never presented to formal medical care, primarily because of the high-perceived cost of care. Untreated hernias caused considerable disability, as 21.9% of participants were unable to work because of their symptoms, and 15.1% of households earned less money. CONCLUSIONS: Hernia is a significant surgical problem in Southwest Cameroon. Despite over half of those with unrepaired hernias reporting symptoms of incarceration, home treatment and nonsurgical management were common. Costs associated with formal medical services are a major barrier to obtaining consultation and repair. Greater awareness of hernia complications and cost restructuring should be considered to prevent disability and mortality due to hernia.

Efficacy and cost-effectiveness of an unguided, internet-based self-help intervention for social anxiety disorder in university students: protocol of a randomized controlled trial.

BACKGROUND: Social anxiety disorder (SAD) is highly prevalent among university students, but the majority of affected students remain untreated. Internet- and mobile-based self-help interventions (IMIs) may be a promising strategy to address this unmet need. This study aims to investigate the efficacy and cost-effectiveness of an unguided internet-based treatment for SAD among university students. The intervention is optimized for the treatment of university students and includes one module targeting fear of positive evaluations that is a neglected aspect of SAD treatment. METHODS: The study is a two arm randomized controlled trial in which 200 university students with a primary diagnosis of SAD will be assigned randomly to either a wait-list control group (WLC) or the intervention group (IG). The intervention consists of 9 sessions of an internet-based cognitive-behavioral treatment, which also includes a module on fear of positive evaluation (FPE). Guidance is delivered only on the basis of standardized automatic messages, consisting of positive reinforcements for session completion, reminders, and motivational messages in response to non-adherence. All participants will additionally have full access to treatment as usual. Diagnostic status will be assessed through Structured Clinical Interviews for DSM Disorders (SCID). Assessments will be completed at baseline, 10 weeks and 6-month follow-up. The primary outcome will be SAD symptoms at post-treatment, assessed via the Social Phobia Scale (SPS) and the Social Interaction Anxiety Scale (SIAS). Secondary outcomes will include diagnostic status, depression, quality of life and fear of positive evaluation. Cost-effectiveness and cost-utility analyses will be evaluated from a societal and health provider perspective. DISCUSSION: Results of this study will contribute to growing evidence for the efficacy and cost-effectiveness of unguided IMIs for the treatment of SAD in university students. Consequently, this trial may provide valuable information for policy makers and clinicians regarding the allocation of limited treatment resources to such interventions.

Develop a home-used EMG sensor system to identify pathological gait with less data via frequency analysis.

In order to develop a low-cost wearable electromyography (EMG) sensor system that can be used at home, compacting the data size is studied first to extract potential features via frequency analysis. A low-cost wearable home-use EMG sensor is then developed. Results show the frequency band at 40-60 Hz of tibialis anterior offers significant differences to identify walking problems (p-value < 0.05), which can be used as a detection standard with a smaller data size. More significantly, data sizes are dramatically reduced by 95.06% compared to the original data size. This finding suggests a potential examining method for identifying pathological gait with the compacted data in satisfactory processing time that can be used at home.
