Cost and Cost-Effectiveness of Students for Nutrition and eXercise (SNaX).

ABSTRACT:

Objective

To examine the cost and cost-effectiveness of implementing Students for Nutrition and eXercise (SNaX), a 5-week middle school-based obesity-prevention intervention combining school-wide environmental changes, multimedia, encouragement to eat healthy school cafeteria foods, and peer-led education.

Methods

Five intervention and 5 control middle schools (mean enrollment, 1520 students) from the Los Angeles Unified School District participated in a randomized controlled trial of SNaX. Acquisition costs for materials and time and wage data for employees involved in implementing the program were used to estimate fixed and variable costs. Cost-effectiveness was determined using the ratio of variable costs to program efficacy outcomes.

Results

The costs of implementing the program over 5 weeks were $5433.26 per school in fixed costs and $2.11 per student in variable costs, equaling a total cost of $8637.17 per school, or $0.23 per student per day. This investment yielded significant increases in the proportion of students served fruit and lunch and a significant decrease in the proportion of students buying snacks. The cost-effectiveness of the program, per student over 5 weeks, was $1.20 per additional fruit served during meals, $8.43 per additional full-priced lunch served, $2.11 per additional reduced-price/free lunch served, and $1.69 per reduction in snacks sold.

Conclusions

SNaX demonstrated the feasibility and cost-effectiveness of a middle school-based obesity-prevention intervention combining school-wide environmental changes, multimedia, encouragement to eat healthy school cafeteria foods, and peer-led education. Its cost is modest and unlikely to be a significant barrier to adoption for many schools considering its implementation.

Project description:IntroductionAlternatives such as remotely delivered therapy in the home environment or telehealth represent an opportunity to increase overall cardiac rehabilitation (CR) utilization. Implementing alternatives into regular practice is the next step in development; however, the cost aspect is essential for policymakers. Limited economic budgets lead to cost-effectiveness analyses before implementation. They are appropriate in cases where there is evidence that the compared intervention provides a similar health benefit to usual care. This systematic review aimed to compare the cost-effectiveness of exercise-based telehealth CR interventions compared to standard exercise-based CR.Evidence acquisitionPubMed and Web of Science databases were systematically searched up to August 2022 to identify randomized controlled trials assessing patients undergoing telehealth CR. The intervention was compared to standard CR protocols. The primary intent was to identify the cost-effectiveness. Interventions that met the criteria were home-based telehealth CR interventions delivered by information and communications technology (telephone, computer, internet, or videoconferencing) and included the results of an economic evaluation, comparing interventions in terms of cost-effectiveness, utility, costs and benefits, or cost-minimization analysis. The systematic review protocol was registered in the PROSPERO Registry (CRD42022322531).Evidence synthesisOut of 1525 identified studies, 67 articles were assessed for eligibility, and, at the end of the screening process, 12 studies were included in the present systematic review. Most studies (92%) included in this systematic review found strong evidence that exercise-based telehealth CR is cost-effective. Compared to CBCR, there were no major differences, except for three studies evaluating a significant difference in average cost per patient and intervention costs in favor of telehealth CR.ConclusionsTelehealth CR based on exercise is as cost-effective as CBCR interventions. Funding telehealth CR by third-party payers may promote patient participation to increase overall CR utilization. High-quality research is needed to identify the most cost-effective design.

Project description:ContextTelehealth-delivered nutrition interventions are effective in practice; however, limited evidence exists regarding their cost-effectiveness.ObjectiveTo evaluate the cost-effectiveness of telehealth-delivered nutrition interventions for improving health outcomes in adults with chronic disease.Data sourcesPubMed, CENTRAL, CINAHL, and Embase databases were systematically searched from database inception to November 2021. Included studies were randomized controlled trials delivering a telehealth-delivered diet intervention conducted with adults with a chronic disease and that reported on cost-effectiveness or cost-utility analysis outcomes.Data extractionAll studies were independently screened and extracted, and quality was appraised using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist.Data analysisAll extracted data were grouped into subcategories according to their telehealth modality and payer perspective, and were analyzed narratively.ResultsTwelve randomized controlled trials comprising 5 phone-only interventions, 3 mobile health (mHealth), 2 online, and 1 each using a combination of phone-online or phone-mHealth interventions, were included in this review. mHealth interventions were the most cost-effective intervention in all studies. Across all telehealth interventions and cost analyses from health service perspectives, 60% of studies were cost-effective. From a societal perspective, however, 33% of studies reported that the interventions were cost-effective. Of the 10 studies using cost-utility analyses, 3 were cost saving and more effective, making the intervention dominant, 1 study reported no difference in costs or effectiveness, and the remaining 6 studies reported increased cost and effectiveness, meaning payers must decide whether this falls within an acceptable willingness-to-pay threshold for them. Quality of study reporting varied with between 63% to 92%, with an average of 77% of CHEERS items reported.ConclusionTelehealth-delivered nutrition interventions in chronic disease populations appear to be cost-effective from a health perspective, and particularly mHealth modalities. These findings support telehealth-delivered nutrition care as a clinically beneficial, cost-effective intervention delivery modality.

Project description:BackgroundThe dearth of health workers in rural settings in Lao People's Democratic Republic (PDR) and other developing countries limits healthcare access and outcomes. In evaluating non-wage financial incentive packages as a potential policy option to attract health workers to rural settings, understanding the expected costs and effects of the various programs ex ante can assist policy-makers in selecting the optimal incentive package.MethodsWe use discrete choice experiments (DCEs), costing analyses and recent empirical results linking health worker density and health outcomes to estimate the future location decisions of physicians and determine the cost-effectiveness of 15 voluntary incentives packages for new physicians in Lao PDR. Our data sources include a DCE survey completed by medical students (n = 329) in May 2011 and secondary cost, economic and health data. Mixed logit regressions provide the basis for estimating how each incentive package influences rural versus urban location choice over time. We estimate the expected rural density of physicians and the cost-effectiveness of 15 separate incentive packages from a societal perspective. In order to generate the cost-effectiveness ratios we relied on the rural uptake probabilities inferred from the DCEs, the costing data and prior World Health Organization (WHO) estimates that relate health outcomes to health worker density.ResultsRelative to no program, the optimal voluntary incentive package would increase rural physician density by 15% by 2016 and 65% by 2041. After incorporating anticipated health effects, seven (three) of the 15 incentive packages have anticipated average cost-effectiveness ratio less than the WHO threshold (three times gross domestic product [GDP] per capita) over a 5-year (30 year) period. The optimal package's incremental cost-effectiveness ratio is $1454/QALY (quality-adjusted life year) over 5 years and $2380/QALY over 30 years. Capital intensive components, such as housing or facility improvement, are not efficient.ConclusionConditional on using voluntary incentives, Lao PDR should emphasize non-capital intensive options such as advanced career promotion, transport subsidies and housing allowances to improve physician distribution and rural health outcomes in a cost-effective manner. Other countries considering voluntary incentive programs can implement health worker/trainee DCEs and costing surveys to determine which incentive bundles improve rural uptake most efficiently but should be aware of methodological caveats.
