ABSTRACT The Centers for Disease Control and Prevention (CDC) recommends offering human immunodeficiency virus (HIV) testing to all patients in all high HIV-prevalence clinical settings. We evaluated programmatic aspects of HIV testing across multiple clinical settings within a single medical center.
We analyzed programmatic data of HIV testing in the Urgent Care Center (UCC), inpatient floors, outpatient primary care, a non-clinical Drop-In Center, and Emergency Department (ED). HIV testing was by oral mucosal transudate, venous blood samples, or rapid testing fingersticks, with Western blot confirmation. We compared the sociodemographics and behavioral risks of individuals undergoing HIV testing across the five sites and estimated costs per person tested and per HIV-positive test result.
From 2002 to 2004, 16,750 HIV tests were conducted, with 229 (1.4%) previously unreported HIV infections diagnosed among 16,696 valid test results. HIV-positive prevalence was 1.5% for the UCC, 1.5% at the Drop-In Center, 1.4% for primary care, 1.2% for inpatient, and 0.6% in the ED. Behavioral risks were most prevalent in the UCC and the Drop-In Center. The cost per test was lowest in the UCC and highest in the Drop-In Center. The cost per previously unreported HIV infection was lowest in the UCC ($1,980) and highest in the ED ($9,724).
Although a significant number of HIV infections were identified, the number of tests performed represents < 10% of all clinical visits. Due to personnel and time constraints, offering HIV testing to patients hierarchically in some settings of a high-volume medical center merits evaluation.

    ABSTRACT: A 2004 national survey of hospitals showed that 23.4% of hospitals screened for HIV in at least one department, most frequently in labor and delivery departments. However, less than 2% of these hospitals screened patients in inpatient units, urgent care clinics, or emergency departments. In 2006, the Centers for Disease Control and Prevention (CDC) recommended HIV screening for all individuals 13-64 years of age in health-care settings. We determined the frequency of hospital adoption of these CDC recommendations. We surveyed hospital infection-control personnel at a randomly selected sample of U.S. general medical and surgical hospitals in 2009-2010. Of the 1,476 hospitals selected for the survey, 754 (51.1%) responded to the survey; of those responding, 703 (93.2%) offered HIV tests for patients at the hospital and 206 (27.3%) screened for HIV in at least one department. Screening was most common in larger hospitals (45.7%), hospitals in large metropolitan areas (50.5%), and teaching hospitals (44.4%); it was least common in public hospitals (19.1%). By department, screening was most common in labor and delivery departments (34.6%) and substance abuse clinics (20.7%); it was least common in emergency departments (11.9%), inpatient units (9.6%), and psychiatry/mental health departments (9.4%). More than half of hospitals were not considering implementing CDC's recommendations within the next 12 months. Since 2004, HIV screening in hospitals increased overall and by department. However, the majority of U.S. hospitals have not adopted the CDC recommendations.

    ABSTRACT: To determine the feasibility and case detection rate of a geographic information systems (GIS)-based integrated community screening strategy for tuberculosis, syphilis, and human immunodeficiency virus (HIV). Prospective cross-sectional study of all participants presenting to geographic hot spot screenings in Wake County, North Carolina. The residences of tuberculosis, HIV, and syphilis cases incident between 1/1/05-12/31/07 were mapped. Areas with high densities of all 3 diseases were designated "hot spots." Combined screening for tuberculosis, HIV, and syphilis were conducted at the hot spots; participants with positive tests were referred to the health department. Participants (N = 247) reported high-risk characteristics: 67% previously incarcerated, 40% had lived in a homeless shelter, and 29% had a history of crack cocaine use. However, 34% reported never having been tested for HIV, and 41% did not recall prior tuberculin skin testing. Screening identified 3% (8/240) of participants with HIV infection, 1% (3/239) with untreated syphilis, and 15% (36/234) with latent tuberculosis infection. Of the eight persons with HIV, one was newly diagnosed and co-infected with latent tuberculosis; he was treated for latent TB and linked to an HIV provider. Two other HIV-positive persons had fallen out of care, and as a result of the study were linked back into HIV clinics. Of 27 persons with latent tuberculosis offered therapy, nine initiated and three completed treatment. GIS-based screening can effectively penetrate populations with high disease burden and poor healthcare access. Linkage to care remains challenging and will require creative interventions to impact morbidity.
