Dataset Information

A multicenter study of initiation of antiretroviral therapy and transmitted drug resistance in antiretroviral-naive adolescents and young adults with HIV in New York City.

ABSTRACT:

Background

In December 2009, the Department of Health and Human Services guidelines for initiation of antiretroviral therapy (ART) changed to include patients with CD4 counts between 350 and 500 cells/µL. The aims of this study were to assess uptake of this recommendation in ART-naive youth with human immunodeficiency virus (HIV) and to describe the epidemiology of transmitted genotypic drug resistance mutations (DRMs) in this population.

Methods

A multicenter, retrospective cohort study of ART initiation in ART-naive youth was performed. Eligible subjects were 13-25 years of age, were diagnosed with HIV within 1 year of presentation to care at the study sites, and presented to care from January 2007 to June 2011.

Results

Of 685 potential subjects identified, 331 (49%) fulfilled inclusion criteria. Mean CD4 count at presentation to care was 452 cells/µL. Overall, 191 (58%) subjects started ART. The mean CD4 count at ART initiation was 261 cells/µL before and 363 cells/µL after the 2009 guideline change (P < .0001). Of 212 (64%) subjects with resistance testing available prior to ART initiation, 38 (18%) subjects had a major DRM and an increased proportion of resistance was seen in later study years.

Conclusions

Our study demonstrated an uptake in recently changed guideline recommendations to treat HIV-infected individuals at higher CD4 counts and reinforces the importance of performing resistance testing at entry into care, as 18% of our population had major DRMs prior to initiation of ART.

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.
