Economic evaluation alongside a clinical trial of near-to-patient testing for sexually transmitted infections.

BACKGROUND: Current clinical care for common bacterial STIs (Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Mycoplasma genitalium (MG)) involves empiric antimicrobial therapy when clients are symptomatic, or if asymptomatic, waiting for laboratory testing and recall if indicated. Near-to-patient testing (NPT) can improve pathogen-specific prescribing and reduce unnecessary or inappropriate antibiotic use in treating sexually transmitted infections (STI) by providing same-day delivery of results and treatment. METHODS: We compared the economic cost of NPT to current clinic practice for managing clients with suspected proctitis, non-gonococcal urethritis (NGU), or as an STI contact, from a health provider's perspective. With a microsimulation of 1000 clients, we calculated the cost per client tested and per STI- and pathogen- detected for each testing strategy. Sensitivity analyses were conducted to assess the robustness of the main outcomes. Costs are reported as Australian dollars (2023). RESULTS: In the standard care arm, cost per client tested for proctitis, NGU in men who have sex with men (MSM) and heterosexual men were the highest at $247.96 (95% Prediction Interval (PI): 246.77-249.15), $204.23 (95% PI: 202.70-205.75) and $195.01 (95% PI: 193.81-196.21) respectively. Comparatively, in the NPT arm, it costs $162.36 (95% PI: 161.43-163.28), $158.39 (95% PI: 157.62-159.15) and $149.17 (95% PI: 148.62-149.73), respectively. Using NPT resulted in cost savings of 34.52%, 22.45% and 23.51%, respectively. Among all the testing strategies, substantial difference in cost per client tested between the standard care arm and the NPT arm was observed for contacts of CT or NG, varying from 27.37% to 35.28%. CONCLUSION: We found that NPT is cost-saving compared with standard clinical care for individuals with STI symptoms and sexual contacts of CT, NG, and MG.

Cost-effectiveness of Sexually Transmitted Infection Screening for Adolescents and Young Adults in the Pediatric Emergency Department.

Importance: Adolescents 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. Objective: To 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 Participants: This 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. Interventions: The 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 Measures: Outcome 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. Results: A 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 Relevance: This 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.

Association of Atopic Dermatitis With Bacterial, Fungal, Viral, and Sexually Transmitted Skin Infections.

BACKGROUND: Atopic dermatitis (AD) is associated with altered skin barrier, microbiome, and immune dysregulation that may increase risk of skin infections. OBJECTIVE: The aim of the study was to determine whether AD is associated with skin infections and related outcomes. METHODS: Data from the 2006 to 2012 National Emergency Department Sample were analyzed, including an approximately 20% sample of all US emergency department (ED) visits (N = 198,102,435 adults or children). RESULTS: Skin infections were increased in ED visits of adults (7.14% vs 3.76%) and children (5.15% vs 2.48%) with AD. In multivariable logistic regression models, AD was associated with significantly higher odds of skin infection in adults (adjusted odds ratio [95% confidence interval] = 1.93 [1.89-1.97]) and children (2.23 [2.16-2.31]). Pediatric and adult AD were associated with significantly higher odds of carbuncle/furuncles, impetigo, cellulitis, erysipelas, methicillin-resistant and methicillin-sensitive Staphylococcus aureus infections, molluscum contagiosum, cutaneous warts, herpes simplex and zoster viruses, eczema herpeticum, dermatophytosis, and candidiasis of skin/nails and vulva/urogenitals. Adults with AD had significantly higher odds of genital warts (1.51 [1.36-1.52]) and herpes (1.23 [1.11-1.35]). Skin infections were associated with US $19 million excess annual costs of ED care in persons with AD. CONCLUSIONS: Atopic dermatitis patients had higher odds of multiple bacterial, viral, fungal, and sexually transmitted skin infections.

An analysis of the development assistance for health (DAH) allocations for STD control in Africa.

The Sustainable Development Goals set by the United Nations recognize the importance of making progress in the eradication and treatment of sexually transmitted deceases (STD). STD are among the most widespread diseases in the world and have the highest prevalence in Sub-Saharan Africa. The current study explored the associations between the allocation of the development assistance for health (DAH) in 54 African countries and key development indicators - STD incidence, Gross Domestic Product per capita, health expenditure, and life expectancy at birth. It employed descriptive statistical methods, the matrix scatter plot analysis and the Pearson correlation test for this purpose. The findings indicated that there was a considerable increase in the volume of the DAH given to control and prevent STD in Africa over the period of 2002-2011. A statistically significant positive association was detected between the STD incidence and the health aid allocations. At the same time, the imbalance in the distribution of the health aid between the major and minor aid recipients in the continent increased. The study concludes by discussing policy implications that can be drawn from these findings.

Cost and cost-effectiveness of point-of-care testing and treatment for sexually transmitted and genital infections in pregnancy in low-income and middle-income countries: a systematic review protocol.

INTRODUCTION: The economic and health burden of sexually transmitted and genital infections (henceforth, STIs) in low-income and middle-income countries (LMICs) is substantial. Left untreated, STIs during pregnancy may result in several adverse pregnancy and birth outcomes. Timely diagnosis and treatment at point-of-care (POC) can potentially improve these outcomes. Despite the availability and promotion of POC diagnostics for STIs as a key component of antenatal care in LMICs, their widespread use has been limited, owing to the high economic costs faced by individuals and health systems. To date, there have been no systematic reviews which explore the cost or cost-effectiveness of POC testing and treatment of STIs in pregnancy in LMICs. The objective of this protocol is to outline the methods that will compare, synthesise and appraise the existing literature in this domain. METHODS AND ANALYSIS: We will conduct literature searches in MEDLINE, Embase and Web of Science. To find additional literature, we will search Google Scholar and hand search reference lists of included papers. Two reviewers will independently search databases, screen titles, abstracts and full texts; when necessary a third reviewer will resolve disputes. Only cost and cost-effectiveness studies of POC testing and treatment of STIs, including syphilis, chlamydia, trichomonas, gonorrhoea and bacterial vaginosis, in pregnancy in LMICs will be included. Published checklists will be used to assess quality of reporting practices and methodological approaches. We will also assess risk of publication bias. Interstudy heterogeneity will be assessed and depending on variation between studies, a meta-analysis or narrative synthesis will be conducted. ETHICS AND DISSEMINATION: Ethical approval is not required as the review will use published literature. The results will be published in a peer-reviewed open source journal and presented at an international conference. PROSPERO REGISTRATION NUMBER: CRD42018109072.

Sexually Transmitted Disease Partner Services Costs, Other Resources, and Strategies Across Jurisdictions to Address Unique Epidemic Characteristics and Increased Incidence.

BACKGROUND: Sexually transmitted disease (STD) partner services (PS) are a core component of STD programs. Data on costs are needed to support PS programming. METHODS: In Washington State STD PS programs, disease intervention specialists (DIS) conduct telephone-based interviews and occasional field visits, offer expedited partner therapy to heterosexuals with gonorrhea or chlamydia, and promote human immunodeficiency virus (HIV) testing, preexposure prophylaxis, and HIV care. We conducted activity-based microcosting of PS, including: observational and self-reported time studies and interviews. We analyzed cost, surveillance, and service delivery data to determine costs per program outcomes. RESULTS: In King, Pierce, and Spokane counties, respectively, DIS allocated 6.5, 6.4, and 28.8 hours per syphilis case and 1.5, 1.6, and 2.9 hours per gonorrhea/chlamydia case, on average. In 2016, each full-time DIS investigated 270, 268, and 61 syphilis and 1177, 1105, and 769 gonorrhea/chlamydia cases. Greater than 80% of syphilis cases in King and Pierce were among men who have sex with men versus 38% in Spokane. Disease intervention specialists spent 12% to 39% of their time actively interviewing cases and notifying partners (clients), and the remaining time locating clients, coordinating and verifying care, and managing case reports. Time spent on expedited partner therapy, HIV testing, and referrals to HIV treatment or preexposure prophylaxis, was minimal (<5 minutes per interview) at locations with resources outside PS staff. Program cost-per-interview ranged from US $527 to US $2210 for syphilis, US $219 to US $484 for gonorrhea, and US $164 to US $547 for chlamydia. DISCUSSION: The STD PS resource needs depended on epidemic characteristics and program models. Integrating HIV prevention objectives minimally impacted PS-specific program costs. Results can inform program planning, future budget impact, and cost-effectiveness analyses.

Medicaid Coverage of Sexually Transmitted Disease Service Visits.

INTRODUCTION: Chlamydia and gonorrhea are the most commonly reported notifiable infections in the U.S., with direct medical costs for the treatment of these infections exceeding $700 million annually. Medicaid currently covers approximately 80 million low-income Americans, including a high percentage of racial and ethnic minorities. Studies have shown that racial and ethnic minority populations, particularly those with low SES, are at an increased risk of acquiring a sexually transmitted disease. Therefore, as Medicaid expands, there will likely be a greater demand for sexually transmitted disease services in community-based physician offices. To determine demand for these services among Medicaid enrollees, this study examined how often Medicaid was used to pay for sexually transmitted disease services received in this setting. METHODS: This study combined 2014 and 2015 data from the National Ambulatory Medical Care Survey and tested for differences in the proportion of visits with an expected payment source of Medicaid when sexually transmitted disease services were and were not provided. All analyses were conducted in October 2018. RESULTS: During 2014-2015, an estimated 25 million visits received a sexually transmitted disease service. Medicaid paid for a greater percentage of sexually transmitted disease visits (35.5%, 95% CI=22.5%, 51.1%) compared with non-sexually transmitted disease visits (12.1%, 95% CI=10.8%, 13.6%). Logistic regression modeling, controlling for age, sex, and race of the patient, showed that visits covered by Medicaid had increased odds of paying for a sexually transmitted disease service visit (OR=1.97, 95% CI=1.12, 3.46), compared with other expected payment sources. CONCLUSIONS: Focusing sexually transmitted disease prevention in Medicaid populations could reduce sexually transmitted disease incidence and resulting morbidity and costs.

Online testing for sexually transmitted infections: A whole systems approach to predicting value.

BACKGROUND: Online testing for sexually transmitted infections has a lower unit cost than testing in clinical services and economic analysis has focused on the cost per test and cost per diagnosis in clinics and online. However, online services generate new demand for testing and shift activity between services, requiring system-level analysis to effectively predict cost-effectiveness. METHODS AND FINDINGS: Routinely collected, anonymised, retrospective data on sexual health service activity from all specialist services (clinic and online) within an inner London sexual health economy were collated and harmonised to generate a complete dataset of individual level clinic attendances. Clinic activity and diagnoses were coded using nationally standardised codes assigned by clinicians. Costs were taken from locally or regionally agreed sexual health tariffs. The introduction of online services changed patterns of testing. In an inner London sexual health economy, online STI testing increased total number of tests, the total cost of testing and total diagnoses while slightly reducing the average cost per diagnosis. Two years after the introduction of online services 37% of tests in the were provided online and total diagnoses increased. The positivity of online services is generally lower than that in clinics but varies between contexts. Where the positivity ratio between clinic and online is less than the cost ratio, online services will reduce cost per diagnosis. In this analysis, areas with different classifications as urban and rural had different clinic/online positivity ratios changing the cost effectiveness between areas. Even after the introduction of online services, simple STI testing activity continues in clinics and providers should consider online-first options where clinically appropriate. CONCLUSIONS: Online services for STI testing are not 'stand alone'. They change STI testing behaviour with impacts on all elements of the sexual health economy. Planning, development and monitoring of such services should reference the dynamic nature of these systems and the role of online services within them.

Evaluation and enumeration of online test providers for sexually transmitted infections, specifically chlamydia, in the Netherlands.

OBJECTIVES: Online testing for STIs might complement regular care provided by general practitioners or STI clinics. Two types of online testing can be distinguished, self-testing and self-sampling (sending sample to a laboratory for diagnosis). Online testing can occur without consultation with a healthcare professional, therefore information given by providers is essential for informed decision-making. We aimed to enumerate online test providers in the Netherlands focusing on chlamydia tests, to evaluate information using quality indicators and to gain insight on the proportion of online testing in the STI testing arena. METHODS: We performed a systematic internet search to identify online STI test providers. Twenty quality indicators were evaluated on their websites; indicator scores were weighted by level of importance (expert opinion). High scoring providers were recommended, on the condition that the sensitivity and specificity of the test were above 95% and providers included a follow-up procedure in case of a positive result. Finally, providers were contacted to inquire about the number of sold tests, positivity rates and demographic characteristics of testers. RESULTS: Five out of 12 identified self-sample test providers could be recommended, versus zero out of eight self-test providers. Self-sample test providers gave complete and correct information on more indicators (67%) compared with self-test providers (38%). In 2015, an estimated 30 000-40 000 self-sample tests were purchased, and 12 000-25 000 self-tests, which is roughly 10%-15% of the total number of STI tests. CONCLUSION: This evaluation shows that some online self-sample test providers could be put forward as way of STI testing complementing regular testing options. None of the self-test providers were recommended. Regularly evaluating online test providers is advised to improve quality of the information on the websites. Finally, self-testing might not be suited for all populations as most information is provided in written format only.

Modelling-based evaluation of the costs, benefits and cost-effectiveness of multipathogen point-of-care tests for sexually transmitted infections in symptomatic genitourinary medicine clinic attendees.

OBJECTIVES: To quantify the costs, benefits and cost-effectiveness of three multipathogen point-of-care (POC) testing strategies for detecting common sexually transmitted infections (STIs) compared with standard laboratory testing. DESIGN: Modelling study. SETTING: Genitourinary medicine (GUM) services in England. POPULATION: A hypothetical cohort of 965 988 people, representing the annual number attending GUM services symptomatic of lower genitourinary tract infection. INTERVENTIONS: The decision tree model considered costs and reimbursement to GUM services associated with diagnosing and managing STIs. Three strategies using hypothetical point-of-care tests (POCTs) were compared with standard care (SC) using laboratory-based testing. The strategies were: A) dual POCT for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG); B) triplex POCT for CT-NG and Mycoplasma genitalium (MG); C) quadruplex POCT for CT-NG-MG and Trichomonas vaginalis (TV). Data came from published literature and unpublished estimates. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcomes were total costs and benefits (quality-adjusted life years (QALYs)) for each strategy (2016 GB, £) and associated incremental cost-effectiveness ratios (ICERs) between each of the POC strategies and SC. Secondary outcomes were inappropriate treatment of STIs, onward STI transmission, pelvic inflammatory disease in women, time to cure and total attendances. RESULTS: In the base-case analysis, POC strategy C, a quadruplex POCT, was the most cost-effective relative to the other strategies, with an ICER of £36 585 per QALY gained compared with SC when using microcosting, and cost-savings of £26 451 382 when using tariff costing. POC strategy C also generated the most benefits, with 240 467 fewer clinic attendances, 808 fewer onward STI transmissions and 235 135 averted inappropriate treatments compared with SC. CONCLUSIONS: Many benefits can be achieved by using multipathogen POCTs to improve STI diagnosis and management. Further evidence is needed on the underlying prevalence of STIs and SC delivery in the UK to reduce uncertainty in economic analyses.

A dynamic Bayesian Markov model for health economic evaluations of interventions in infectious disease.

BACKGROUND: Health economic evaluations of interventions in infectious disease are commonly based on the predictions of ordinary differential equation (ODE) systems or Markov models (MMs). Standard MMs are static, whereas ODE systems are usually dynamic and account for herd immunity which is crucial to prevent overestimation of infection prevalence. Complex ODE systems including distributions on model parameters are computationally intensive. Thus, mainly ODE-based models including fixed parameter values are presented in the literature. These do not account for parameter uncertainty. As a consequence, probabilistic sensitivity analysis (PSA), a crucial component of health economic evaluations, cannot be conducted straightforwardly. METHODS: We present a dynamic MM under a Bayesian framework. We extend a static MM by incorporating the force of infection into the state allocation algorithm. The corresponding output is based on dynamic changes in prevalence and thus accounts for herd immunity. In contrast to deterministic ODE-based models, PSA can be conducted straightforwardly. We introduce a case study of a fictional sexually transmitted infection and compare our dynamic Bayesian MM to a deterministic and a Bayesian ODE system. The models are calibrated to simulated time series data. RESULTS: By means of the case study, we show that our methodology produces outcome which is comparable to the "gold standard" of the Bayesian ODE system. CONCLUSIONS: In contrast to ODE systems in the literature, the dynamic MM includes distributions on all model parameters at manageable computational effort (including calibration). The run time of the Bayesian ODE system is 15 times longer.

State Laws Related to Billing Third Parties for Health Care Services at Public Sexually Transmitted Disease Clinics in the United States.

BACKGROUND: Health departments (HDs) cite state laws as barriers to billing third parties for sexually transmitted disease (STD) services, but the association between legal/policy barriers and third-party HD billing has not been examined. This study investigates the relationship between laws that may limit HDs' ability to bill, clinic perceptions of billing barriers, and billing practices. METHODS: Two surveys, (1) clinic managers (n = 246), (2) STD program managers (n = 63), conducted via a multiregional needs assessment of federally funded HD clinics' capacity to bill for STD services, billing/reimbursement practices, and perceived barriers were combined with an analysis of state laws regarding third-party billing for STD services. Statistical analyses examined relationships between laws that may limit HDs' ability to bill, clinic perceptions, and billing practices. RESULTS: Clinic managers reported clinics were less likely to bill Medicaid and other third parties in jurisdictions with a state law limiting their ability to bill compared with respondents who billed neither or 1 payer (odds ratio [OR], 0.31; 95% confidence interval [CI], 0.10-0.97) and cited practical concerns as a primary barrier to billing (OR, 2.83; 95% CI, 1.50-5.37). The STD program managers report that the staff believed that STD services should be free (OR, 0.34; 95% CI, 0.13-0.90) was associated with not billing (not sure versus no resistance to billing); confidentiality concerns was not a reported barrier to billing among either sample. CONCLUSIONS: Practical concerns and clinic staff beliefs that STD services should be free emerged as possible barriers to billing, as were laws to a lesser extent. Attempts to initiate HD billing for STD services may benefit from staff education as well as addressing perceived legal barriers and staff concerns.

The Impact of Budget Cuts on Sexually Transmitted Disease Programmatic Activities in State and Local Health Departments With Staffing Reductions in Fiscal Year 2012.

Staffing reductions in state and local health departments in fiscal year 2012 were concentrated in disease investigation specialists and clinicians (local) and disease investigation specialists and administrative staff (state). Local health departments with budget cuts were significantly more likely to report reduced partner services if they had staffing reductions.

The Use of Technology for Sexually Transmitted Disease Partner Services in the United States: A Structured Review.

BACKGROUND: Since the late 1990s, health departments and sexually transmitted disease (STD) programs throughout the United States have used technologies, such as the Internet and mobile phones, to provide services to persons with a sexually transmitted infection, including human immunodeficiency virus (HIV), and their sex partners, also known as partner services. This study reviewed the published literature to assess and compare partner services outcomes as a result of using technology and to calculate cost savings through cases averted. METHODS: We conducted a structured literature review of all US studies that examined the use of technology to notify persons exposed to an STD (syphilis, chlamydia, gonorrhea), including HIV, by health care professionals in the United States from 2000 to 2017. Outcome measures, including the number of partners notified, screened or tested; and new positives identified, were captured and cost savings were calculated, when data were available. RESULTS: Seven studies were identified. Methods used for partner services differed across studies, although email was the primary mode in 6 (83%) of the 7 studies. Only 2 of the 7 studies compared use of technology for partner services to traditional partner services. Between 10% and 97% of partners were successfully notified of their exposure through the use of technology and between 34% and 81% were screened or tested. Five studies reported on new infections identified, which ranged from 3 to 19. Use of technology for partner serves saved programs between US $22,795 and US $45,362 in direct and indirect medical costs. CONCLUSIONS: Use of technology for partner services increased the number of partners notified, screened or tested, and new infections found. Importantly, the use of technology allowed programs to reach partners who otherwise would not have been notified of their exposure to an STD or HIV. Improved response times and time to treatment were also seen as was re-engagement into care for previous HIV positive patients. Data and outcome measures across the studies were not standardized, making it difficult to generalize conclusions. Although not a replacement for traditional partner services, the use of technology enhances partner service outcomes.

Recent Changes in Prevention Funding to Areas With High Racial and Ethnic Disparities in Sexually Transmitted Disease Rates.

We examined changes in federal sexually transmitted disease funding allocations to areas with high racial/ethnic disparities in sexually transmitted diseases after the implementation of a funding formula in 2014. The funding formula increased prevention funding allocations to areas with high relative racial/ethnic disparities. Results were mixed for areas with high absolute disparities.

[An assessment of the direct costs of healthcare for victims of sexual assaults in hospital emergency units]. / Évaluation des coûts directs de la prise en charge en urgence d'une victime de violences sexuelles.

BACKGROUND: The Forensic medicine reform in 2011 enabled the development of forensic units specialized in multidisciplinary care of victims of criminal offences. Thanks to an annual budgetary allocation, the Ministry of Justice handles the financing of judicial acts, while the health care facilities assume the medical, psychological and social aspects. The objective of this study was to determine the direct costs of medical care provided to rape victims (such as defined in the article 222-23 of the Penal Code) in order to see how its funding could be reconsidered to prevent any additional cost that could be caused by non-sufficient medical, psychological and social care. Furthermore, this first assessment may serve as a basis for further reflection on creating other medical judicial units but also for reviewing existing structures. METHODS: The direct costs for medical care of a recent rape victim (<48hours) was quantified by including staff and consumables costs, treatments, biological tests and other expenses. RESULTS: The overall time for the entire medical care procedure was approximately three hours, for an overall cost of 673.92€, of which 41.5 % (279.90€) was paid by the Ministry of Justice. The medical, psychological and social aspects stood for the major expenditure items (394.02€), attributable mainly to the biological screening tests for sexually transmissible infections (STIs). CONCLUSION: These frequent situations require the convergence of human and material needs with a financial burden shared between the Ministry of Justice and health establishments. Authors suggest that in the annual hospital budgetary allocation allotted by the Ministry of Justice, the care of victims of sexual assault be based on the rate of day hospitalization "Medicine, medical specialties part time day or night common regime", allowing to provide optimal multidisciplinary care, which lessens the risks of complications and reduces the global cost created by these situations.
