Comparison of Targeted and Routine Adolescent HIV Screening in a Pediatric Emergency Department

OBJECTIVES

The aims of the study were (1) to compare targeted and routine HIV screening in a pediatric emergency department (PED) and (2) to compare provider documented HIV risk assessment with adolescent perception of HIV risk assessment conducted during the PED visit.

METHODS

This prospective study ran concurrent to a PED routine HIV screening pilot. Adolescents could be tested for HIV by the PED provider per usual care (targeted testing); if not tested, they were approached for the routine screening pilot. A subset of adolescents completed a questionnaire on HIV risk. χ 2 analysis compared adolescents with targeted testing and routine screening. HIV-tested patients were asked if HIV risk was assessed; κ analysis compared this with documentation in the provider note.

RESULTS

Over 4 months, 107 adolescents received targeted testing and 344 received routine screening. One 14-year-old patient tested positive by routine screening; this adolescent had 2 PED visits without targeted testing within 60 days. Compared with routine screening, adolescents with targeted testing were more likely female (82% vs 57%, P < 0.001), 16 years or older (71% vs 44%, P < 0.001), or had genitourinary/gynecologic concerns (48% vs 6%, P < 0.001). Adolescents with HIV risk factors were missed by targeted testing but received routine screening. Adolescents with documented HIV risk assessment were more likely to receive targeted testing. There was moderate agreement (κ = 0.61) between provider documentation and adolescent perception of HIV risk assessment.

CONCLUSIONS

There are gaps in PED HIV risk assessment and testing, which may miss opportunities to diagnose adolescent HIV. Routine HIV screening addresses these gaps and expands adolescent HIV testing in the PED.

Unique Needs for the Implementation of Emergency Department Human Immunodeficiency Virus Screening in Adolescents

BACKGROUND

The Centers for Disease Control and Prevention (CDC) recommend universal human immunodeficiency virus (HIV) screening starting at 13 years, which has been implemented in many general U.S. emergency departments (EDs) but infrequently in pediatric EDs. We aimed to 1) implement a pilot of routine adolescent HIV screening in a pediatric ED and 2) determine the unique barriers to CDC-recommended screening in this region of high HIV prevalence.

METHODS

This was a prospective 4-month implementation of a routine HIV screening pilot in a convenience sample of adolescents 13 to 18 years at a single pediatric ED, based on study personnel availability. Serum-based fourth-generation HIV testing was run through a central laboratory. Parents were allowed to remain in the room for HIV counseling and testing. Data were collected regarding patient characteristics and HIV testing quality metrics. Comparisons were made using chi-square and Fisher's exact tests. Regression analysis was performed to assess for an association between parent presence at the time of enrollment and adolescent decision to participate in HIV screening.

RESULTS

Over 4 months, 344 of 806 adolescents approached consented to HIV screening (57% female, mean ± SD = 15.1 ± 1.6 years). Adolescents with HIV screening were more likely to be older than those who declined (p = 0.025). Other blood tests were collected with the HIV sample for 21% of adolescents; mean time to result was 105 minutes (interquartile range = 69 to 123) and 79% were discharged before the result was available. Having a parent present for enrollment was not associated with adolescent participation (adjusted odds ratio = 1.07, 95% CI = 0.67 to 1.70). Barriers to testing included: fear of needlestick, time to results, cost, and staff availability. One of 344 tests was positive in a young adolescent with Stage 1 HIV.

CONCLUSIONS

Routine HIV screening in adolescents was able to be implemented in this pediatric ED and led to the identification of early infection in a young adolescent who would have otherwise been undetected at this stage of disease. Addressing the unique barriers to adolescent HIV screening is critical in high-prevalence regions and may lead to earlier diagnosis and treatment in this vulnerable population.
