HIV testing in US EDs, 1993-2004.

OBJECTIVES: The aims of the study were to (1) estimate the incidence rates (IRs) of human immunodeficiency virus (HIV) testing among 13-year-old to 64-year-old patients in US emergency departments (EDs); (2) determine ED compliance with Centers for Disease Control and Prevention (CDC) recommendations for HIV testing for patients with nonsexual blood or body fluid exposures, sexually transmitted diseases (STDs), and sexual assaults; and (3) ascertain if HIV testing in EDs varies by patient demographic characteristics. METHODS: The ED visits from the National Hospital Ambulatory Medical Care Survey databases (1993-2004) were analyzed. Visits for nonsexual blood or body fluid exposures, STDs, and sexual assaults were identified using diagnosis and cause codes. Incidence rates for HIV testing were estimated by year. Odds ratios (ORs) with 95% confidence intervals were estimated from multivariable logistic regression models using HIV testing as the outcome and demographic characteristics as covariates. RESULTS: The average IR of HIV testing for 13-year-old to 64-year-old patients from 1993 to 2004 was 0.31%. Of all patients, 35.1% with nonsexual blood or body fluid exposures, 20.4% with sexual assaults, and 2.6% with STDs were tested for HIV. The HIV testing was more frequent among Hispanics (OR, 1.39 [1.06-1.81]), blacks (OR, 1.52 [1.19-1.94]), patients with Medicaid (OR, 2.35 [1.81-3.03]), Medicare (OR, 1.95 [1.20-3.16]), and self-pay/no charge/other type of insurance (OR, 1.74 [1.35-2.23]), and those visiting EDs in the northeastern United States (OR, 1.57 [1.04-2.38]). CONCLUSIONS: The HIV testing rates are low in US EDs and have changed little for a 12-year period. Compliance with CDC recommendations for HIV testing is poor and not in accordance with risk for infection. Hispanics, blacks, and those without private health care insurance are being tested more frequently than other ED patients.

Demographic variations in HIV testing history among emergency department patients: implications for HIV screening in US emergency departments.

OBJECTIVE: To determine the proportion of emergency department (ED) patients who have been tested for human immunodeficiency virus (HIV) infection and assess if patient history of HIV testing varies according to patient demographic characteristics. DESIGN: From July 2005-July 2006, a random sample of 18-55-year-old English-speaking patients being treated for sub-critical injury or illness at a northeastern US ED were interviewed on their history of HIV testing. Logistic regression models were created to compare patients by their history of being tested for HIV according to their demography. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated. RESULTS: Of 2107 patients surveyed who were not known to be HIV-infected, the median age was 32 years; 54% were male, 71% were white, and 45% were single/never married; 49% had private health-care insurance and 45% had never been tested for HIV. Of the 946 never previously tested for HIV, 56.1% did not consider themselves at risk for HIV. In multivariable logistic regression analyses, those less likely to have been HIV tested were male (OR: 1.32 [1.37-2.73]), white (OR: 1.93 [1.37-2.73]), married (OR: 1.53 [1.12-2.08]), and had private health-care insurance (OR: 2.10 [1.69-2.61]). There was a U-shaped relationship between age and history of being tested for HIV; younger and older patients were less likely to have been tested. History of HIV testing and years of formal education were not related. CONCLUSION: Almost half of ED patients surveyed had never been tested for HIV. Certain demographic groups are being missed though HIV diagnostic testing and screening programmes in other settings. These groups could potentially be reached through universal screening.
