Cost-Effectiveness Analysis of Michigan's School-Wide Sexually Transmitted Disease Screening Program in Four Detroit High Schools.
Ontology highlight
ABSTRACT: Purpose
The Michigan Department of Health and Human Services, in collaboration with St. John Providence Health System, initiated voluntary school-wide sexually transmitted disease (STD) screenings in four Detroit public high schools. We sought to assess the cost-effectiveness of the STD screening program from 2010 to 2015, with a focus on chlamydia.Methods
The costs and effectiveness of the school-based screening were compared with those of a "no school screening" scenario using a healthcare system perspective. A decision tree model was constructed to project cases of chlamydia, epididymitis, and pelvic inflammatory disease (PID) in each of the two scenarios among students tested positive and their partners. Health effects were measured as cases of PID prevented, and quality-adjusted life-years (QALYs) gained. Cost estimates included program costs, chlamydia testing/treatment costs in the absence of school screening, and treatment costs for epididymitis, PID, and PID sequelae. The incremental cost-effectiveness ratio (ICER) was measured as cost/QALY gained. Multivariate sensitivity analyses were conducted on key parameter estimates and assumptions used.Results
Under base-case assumptions, at a total program cost of $333,848 over 5 years, the program prevented an estimated 1.9 cases of epididymitis and 17.3 cases of PID, resulting in an ICER of $38,235/QALY gained (yearly ICER ranging from $27,417 to $50,945/QALY). Of 10,000 Monte Carlo simulation runs, the yearly ICER remained ≤$50,000/QALY in 64%-98% of the simulation runs.Conclusions
We found favorable cost-effectiveness ratios for Michigan's school-wide STD screening program in Detroit. School-based STD screening programs of this type warrant careful considerations by policy makers and program planners.

Project description:BackgroundTo assess from a societal perspective the incremental cost-effectiveness of the Walking School Bus (WSB) program for Australian primary school children as an obesity prevention measure. The intervention was modelled as part of the ACE-Obesity study, which evaluated, using consistent methods, thirteen interventions targeting unhealthy weight gain in Australian children and adolescents.MethodsA logic pathway was used to model the effects on body mass index [BMI] and disability-adjusted life years [DALYs] of the Victorian WSB program if applied throughout Australia. Cost offsets and DALY benefits were modelled until the eligible cohort reached 100 years of age or death. The reference year was 2001. Second stage filter criteria ('equity', 'strength of evidence', 'acceptability', feasibility', sustainability' and 'side-effects') were assessed to incorporate additional factors that impact on resource allocation decisions.ResultsThe modelled intervention reached 7,840 children aged 5 to 7 years and cost $AUD22.8M ($16.6M; $30.9M). This resulted in an incremental saving of 30 DALYs (7:104) and a net cost per DALY saved of $AUD0.76M ($0.23M; $3.32M). The evidence base was judged as 'weak' as there are no data available documenting the increase in the number of children walking due to the intervention. The high costs of the current approach may limit sustainability.ConclusionUnder current modelling assumptions, the WSB program is not an effective or cost-effective measure to reduce childhood obesity. The attribution of some costs to non-obesity objectives (reduced traffic congestion and air pollution etc.) is justified to emphasise the other possible benefits. The program's cost-effectiveness would be improved by more comprehensive implementation within current infrastructure arrangements. The importance of active transport to school suggests that improvements in WSB or its variants need to be developed and fully evaluated.

Project description:Background and objectiveImpoverished urban children suffer disproportionately from asthma and underuse preventive asthma medications. The objective of this study was to examine cost-effectiveness (CE) of the School-Based Asthma Therapy (SBAT) program compared with usual care (UC).MethodsThe analysis was based on the SBAT trial, including 525 children aged 3 to 10 years attending urban preschool or elementary school who were randomized to either UC or administration of 1 dose of preventive asthma medication at school by the school nurse each school day. The primary outcome was the mean number of symptom-free days (SFDs). The impact of the intervention on medical costs was estimated by using parent-reported child health services utilization data and average national reimbursement rates. We estimated the cost of running the program using wages for program staff. Productivity costs were estimated by using value of parent lost time due to child illness. CE of the SBAT program compared with UC was evaluated based on the incremental CE ratio.ResultsThe health benefit of the intervention was equal to ∼158 SFD gained per each 30-day period (P < .05) per 100 children. The programmatic expenses summed to an extra $4822 per 100 children per month. The net saving due to the intervention (reduction in medical costs and parental productivity, and improvement in school attendance) was $3240, resulting in the incremental cost-savings difference of $1583 and CE of $10 per 1 extra SFD gained.ConclusionsThe SBAT was effective and cost-effective in reducing symptoms in urban children with asthma compared with other existing programs.

Project description:BackgroundThe estimated number of people living with hepatitis B virus (HBV) infection acquired through sexual transmission was 103,000 in 2018, with an estimated incidence of 8300 new cases per year. Although hepatitis B (HepB) vaccination is recommended by the Advisory Committee for Immunization Practices for persons seeking evaluation and treatment for sexually transmitted infections (STIs), prevaccination testing is not yet recommended. Screening may link persons with chronic hepatitis B to care and reduce unnecessary vaccination.MethodsWe used a Markov model to calculate the health impact and cost-effectiveness of 1-time HBV testing combined with the first dose of the HepB vaccine for adults seeking care for STI. We ran a lifetime, societal perspective analysis for a hypothetical population of 100,000 aged 18 to 69 years. The disease progression estimates were taken from recent cohort studies and meta-analyses. In the United States, an intervention that costs less than $100,000 per quality-adjusted life-year (QALY) is generally considered cost-effective. The strategies that were compared were as follows: (1) vaccination without HBV screening, (2) vaccination and hepatitis B surface antigen (HBsAg) screening, (3) vaccination and screening with HBsAg and anti-HBs, and (4) vaccination and screening with HBsAg, anti-HBs, and anti-HBc. Data were obtained from Centers for Medicare & Medicaid services reimbursement, the Centers for Disease Control and Prevention vaccine price list, and additional cost-effectiveness literature.ResultsCompared with current recommendations, the addition of 1-time HBV testing is cost-saving and would prevent an additional 138 cases of cirrhosis, 47 cases of decompensated cirrhosis, 90 cases of hepatocellular carcinoma, 33 liver transplants, and 163 HBV-related deaths, and gain 2185 QALYs, per 100,000 adults screened. Screening with the 3-test panel would save $41.6 to $42.7 million per 100,000 adults tested compared with $41.5 to $42.5 million for the 2-test panel and $40.2 to $40.3 million for HBsAg alone.ConclusionsOne-time HBV prevaccination testing in addition to HepB vaccination for unvaccinated adults seeking care for STI would save lives and prevent new infections and unnecessary vaccination, and is cost-saving.

Project description:BackgroundPrimary health-care professionals play an important role in the treatment and prevention of Sexually Transmitted Infections (STI). Continuing Medical Education (CME)-courses can influence the knowledge and behavior of health-care professionals concerning STI. We performed a prospective cohort study to evaluate if the individual and online e-learning program "The STI-consultation", which uses the Commitment-to-Change (CtC)-method, is able to improve the knowledge, attitude and behavior of Dutch General Practitioners (GPs), concerning the STI-consultation. This e-learning program is an individual, accredited, online CME-program, which is freely available for all GPs and GP-trainees in the Netherlands.MethodsIn total 2192 participants completed the questionnaire before completing the e-learning program and 249 participants completed the follow-up questionnaire after completing the e-learning program. The effect of the program on their knowledge, attitude and behavior concerning the STI-consultation was evaluated.ResultsIn total 193 participants formulated 601 learning points that matched the learning objectives of the program. The knowledge and attitude of the participants improved, which persisted up to two years after completing the program. Another 179 participants formulated a total of 261 intended changes concerning the sexual history taking, additional investigation and treatment of STI, 97.2% of these changes was partially or fully implemented in daily practice. Also, 114 participants formulated a total of 180 "unintended" changes in daily practice. These changes concerned the attitude of participants towards STI and the working conditions concerning the STI-consultation.ConclusionThe individual, online e-learning program "The STI-consultation", which uses the CtC-method, has a small but lasting, positive effect on the knowledge, attitude, and behavior of GPs concerning the STI-consultation.

Project description:ImportanceAdolescents and young adults compose almost 50% of all diagnosed sexually transmitted infection (STI) cases annually in the US. Given that these individuals frequently access health care through the emergency department (ED), the ED could be a strategic venue for examining the identification and treatment of STIs.ObjectiveTo examine the cost-effectiveness of screening strategies for Chlamydia trachomatis and Neisseria gonorrhoeae (chlamydia and gonorrhea) in adolescents and young adults who seek acute care at pediatric EDs.Design, setting, and participantsThis economic evaluation is a component of an ongoing, larger multicenter clinical trial at the Pediatric Emergency Care Applied Research Network. A decision analytic model, created using literature-based estimates for the key parameters, was developed to simulate the events and outcomes associated with 3 strategies for screening and testing chlamydial and gonococcal infections in individuals aged 15 to 21 years who sought acute care at pediatric EDs. Data sources included published (from January 1, 1997, to December 31, 2019) English-language articles indexed in MEDLINE, bibliographies in relevant articles, insurance claims data in the MarketScan database, and reimbursement payments from the Centers for Medicare and Medicaid Services. Because the events and outcomes were simulated, a hypothetical population of 10 000 ED visits by adolescents and young adults was used.InterventionsThe 3 screening strategies were (1) no screening, (2) targeted screening, and (3) universally offered screening. Targeted screening involved the completion of a sexual health survey, which yielded an estimated STI risk (at risk, high risk, or low risk).Main outcomes and measuresOutcome metrics included cost (measured in 2019 US dollars) and the detection and successful treatment of STIs. The incremental cost-effectiveness ratio (ICER) of each strategy was calculated in a base case analysis. The ICER reflects the cost per case detected and successfully treated.ResultsA 3.6% prevalence of chlamydia and gonorrhea was applied to a hypothetical population of 10 000 ED visits by adolescents and young adults. Targeted screening resulted in the detection and successful treatment of 95 of 360 STI cases (26.4%) at a cost of $313 063, and universally offered screening identified and treated 112 of 360 STI cases (31.1%) at a cost of $515 503. The ICER for targeted screening vs no screening was $6444, and the ICER for universally offered screening vs targeted screening was $12 139.Conclusions and relevanceThis economic evaluation found that targeted screening and universally offered screening compared with no screening appeared to be cost-effective strategies for identifying and treating chlamydial and gonococcal infections in adolescents and young adults who used the ED for acute care. Universally offered screening was associated with detecting and successfully treating a higher proportion of STIs in this population.

Project description:BackgroundThe expansion of malaria prevention and control to school-aged children is receiving increasing attention, but there are still limited data on the costs of intervention. This paper analyses the costs of a comprehensive school-based intervention strategy, delivered by teachers, that included participatory malaria educational activities, distribution of long lasting insecticide-treated nets (LLIN), and Intermittent Parasite Clearance in schools (IPCs) in southern Mali.MethodsCosts were collected alongside a randomised controlled trial conducted in 80 primary schools in Sikasso Region in Mali in 2010-2012. Cost data were compiled between November 2011 and March 2012 for the 40 intervention schools (6413 children). A provider perspective was adopted. Using an ingredients approach, costs were classified by cost category and by activity. Total costs and cost per child were estimated for the actual intervention, as well as for a simpler version of the programme more suited for scale-up by the government. Univariate sensitivity analysis was performed.ResultsThe economic cost of the comprehensive intervention was estimated to $10.38 per child (financial cost $8.41) with malaria education, LLIN distribution and IPCs costing $2.13 (20.5%), $5.53 (53.3%) and $2.72 (26.2%) per child respectively. Human resources were found to be the key cost driver, and training costs were the greatest contributor to overall programme costs. Sensitivity analysis showed that an adapted intervention delivering one LLIN instead of two would lower the economic cost to $8.66 per child; and that excluding LLIN distribution in schools altogether, for example in settings where malaria control already includes universal distribution of LLINs at community-level, would reduce costs to $4.89 per child.ConclusionsA comprehensive school-based control strategy may be a feasible and affordable way to address the burden of malaria among schoolchildren in the Sahel.

Project description:During the 2015-2016 school year, the Florida Department of Health in Duval County hosted Teen Health Centers (TeenHC) at five high schools of Jacksonville providing HIV/STD screening and pregnancy testing. The purpose of this study was to assess the cost-effectiveness of the TeenHC chlamydia screening program and determine at what student participation level, the program can be cost-effective. We assessed the costs and effectiveness of the chlamydia screening program compared with "no TeenHC". Cost-effectiveness was measured as cost per quality-adjusted life years (QALY) gained. At a program cost of US$61,001 and 3% participation rate, the cost/QALY gained was $124,328 in the base-case analysis and $81,014-$264,271 in 95% of the simulation trials, all greater than the frequently citied $50,000/QALY benchmark. The cost/QALY gained could be <$50,000/QALY if student participation rate was >7%. The TeenHC chlamydia screening has the potential to be cost-effective. Future program efforts should focus on improving student participation.

Project description:BackgroundThere is growing research support for the use of mindfulness training (MT) in schools, but almost no high-quality evidence about different training models for people wishing to teach mindfulness in this setting. Effective dissemination of MT relies on the development of scalable training routes.ObjectiveTo compare 4 training routes for school teachers wishing to deliver MT differing in intensity and potential scalability, considering teaching competency, training acceptability, and cost-effectiveness.MethodsSchools were randomized to an existing route comprising an 8-session instructor-led personal mindfulness course, combined with 4-day MT program training, or 1 of 3 more scalable, lower intensity, alternatives: an instructor-led personal mindfulness course combined with 1-day MT program training, a self-taught personal mindfulness course (delivered through a course book) combined with 4-day MT program training, and a self-taught personal mindfulness course combined with 1-day MT program training.ResultsAttrition from training was substantial across all routes. The instructor-led course was more effective than the self-taught course in increasing teachers' personal mindfulness skills. Even the most intensive (existing) training route brought only 29% of the teachers commencing training, and 56% of those completing the study protocol, to the required minimum competency threshold (an advanced beginner rating on an adapted version of the Mindfulness-based Interventions Teaching Assessment Criteria). The differences in levels of competency achieved by existing training compared with the more scalable alternatives were modest, with economic evaluation suggesting that the existing route was both more expensive and more effective than lower intensity alternatives, but with no statistically significant differences between routes.ConclusionsThis research questions the move toward abbreviating teacher training to increase scalability and suggests instead that many teachers require additional support to ensure competency from first delivery of MT in the classroom.

Project description:ObjectiveThis study aims to assess the variance of the cost-effectiveness ratio of the school-based oral health promotion and prevention program for elementary school children.MethodsThis review protocol was registered in the international database of Prospectively Registered Systematic Reviews in Health and Social Care (PROSPERO) (No: CRD 42022326734). The search for articles conducted in March-April 2022 focuses on any kind of school-based Promotive and Preventive Program for elementary school children that have control groups, and the outcome was Incremental Cost-Effectiveness Ratio (ICER). Grey literatures are not eligible. This review used five databases (PubMed, Scopus, Web of Science, CINAHL, and Google Scholar). Two independent reviewers referred to the PICO for inclusion and exclusion criteria and carried out the systematic review process. JBI ACTUARI Guidance for Critical Appraisal of Economic Evaluation Assessment Tools was used to assess the quality of the study.ResultsOf the total 1,473 articles found, there were 5 articles that matched the article search criteria and were included in a systematic review. It was known that the labor cost has a large proportion of the total program cost, and cost-saving programs were found in the two milk fluoridation programs (18.59 USD and 1.7 USD/averted DMF-S), fluoride mouth rinsing program (10.86 USD), and a comprehensive program with glass ionomer cement (461,766.37 USD/averted DALYs).ConclusionThe fluoride programs and the comprehensive program with glass ionomer cement have the lowest cost-effectiveness ratio.

Project description:BackgroundIt is well established that network structure strongly influences infectious disease dynamics. However, little is known about how the network structure impacts the cost-effectiveness of disease control strategies. We evaluated partner management strategies to address bacterial sexually transmitted infections (STIs) as a case study to explore the influence of the network structure on the optimal disease management strategy.MethodsWe simulated a hypothetical bacterial STI spread through 4 representative network structures: random, community-structured, scale-free, and empirical. We simulated disease outcomes (prevalence, incidence, total infected person-months) and cost-effectiveness of 4 partner management strategies in each network structure: routine STI screening alone (no partner management), partner notification, expedited partner therapy, and contact tracing. We determined the optimal partner management strategy following a cost-effectiveness framework and varied key compliance parameters of partner management in sensitivity analysis.ResultsFor the same average number of contacts and disease parameters in our setting, community-structured networks had the lowest incidence, prevalence, and total infected person-months, whereas scale-free networks had the highest without partner management. The highly connected individuals were more likely to be reinfected in scale-free networks than in the other network structures. The cost-effective partner management strategy depended on the network structures, the compliance in partner management, the willingness-to-pay threshold, and the rate of external force of infection.ConclusionsOur findings suggest that contact network structure matters in determining the optimal disease control strategy in infectious diseases. Information on a population's contact network structure may be valuable for informing optimal investment of limited resources.
