Background UK guidance recommend all acute medical admissions be offered an HIV test. Our aim was to determine whether a dedicated staff member using a multimedia tool, a model found to be effective in the USA, is an acceptable, feasible, and cost-effective model when translated to a UK setting. Design Between 14th Jan to 12th May 2010, a Health advisor (HA) approached 19–65 year olds at a central London acute medical admissions unit (AAU) and offered a rapid HIV point of care test (POCT) with the aid of an educational video. Patients with negative results had the option to watch a post-test video providing risk-reduction information. For reactive results the HA arranged a confirmatory test, and ensured linkage into HIV specialist care. Feasibility and acceptability were assessed through surveys and uptake rates. Costs per case of HIV identified were established. Results Of the 606 eligible people admitted during the pilot period, 324 (53.5%) could not be approached or testing was deemed inappropriate. In total 23.0% of eligible admissions had an HIV POCT. Of the patients who watched the video and had not recently tested for HIV, 93.6% (131/140) agreed to an HIV test; four further patients had an HIV test but did not watch the video. Three tests (2.2%, 3/135) were reactive and all were confirmed HIV positive on laboratory testing. 97.5% felt HIV testing in this setting was appropriate, and 90.1% liked receiving the information via video. The cost per patient of the intervention was £21. Discussion Universal POCT HIV testing in an acute medical setting, facilitated by an educational video and dedicated staff appears to be acceptable, feasible, effective, and low cost. These findings support the recommendation of HIV testing all admissions to AAU in high prevalence settings, although with the model used a significant proportion remained untested.

Early diagnosis of persons infected with human immunodeficiency virus (HIV) through diagnostic testing and screening is a critical priority for individual and public health. Emergency departments (EDs) have an important role in this effort. As EDs gain experience in HIV testing, it is increasingly apparent that implementing testing is conceptually and operationally complex. A wide variety of HIV testing practice and research models have emerged, each reflecting adaptations to site-specific factors and the needs of local populations. The diversity and complexity inherent in nascent ED HIV testing practice and research are associated with the risk that findings will not be described according to a common lexicon. This article presents a comprehensive set of terms and definitions that can be used to describe ED-based HIV testing programs, developed by consensus opinion from the inaugural meeting of the National ED HIV Testing Consortium. These definitions are designed to facilitate discussion, increase comparability of future reports, and potentially accelerate wider implementation of ED HIV testing.

Abstract:One in 5 people living with HIV are unaware of their status; they account for an estimated 51% of new infections. HIV transmission can be reduced through a “Test and Treat” strategy, which can decrease both viral load and risk behaviors. However, linkage of newly diagnosed HIV-positive persons to care has proved challenging. We report quantitative and qualitative data on linkage to care from HIV testing sites that partnered with the New York City Department of Health and Mental Hygiene to implement “The Bronx Knows” (TBK), an initiative that tested 607,570 residents over 3 years. During TBK, partner agencies reported the aggregate number of HIV tests conducted, the number of confirmed positives (overall and new), and the number of confirmed positives linked to medical care. We conducted qualitative interviews with directors of 24 of 30 TBK HIV testing agencies to identify linkage barriers and selected 9 for case studies. Barriers to linkage fell into 3 domains: (1) health care system factors (long wait for provider appointments, requirement of a positive confirmatory test before scheduling an appointment, system navigation, and disrespect to patients); (2) social factors (HIV stigma); and (3) characteristics of risk populations (eg, mental illness, homelessness, substance use, and immigrant). Best practices for linkage included networking among community organizations, individualized care plans, team approach, comprehensive and coordinated care services, and patient peer navigation. Research and public health implications are discussed.

New Centers for Disease Control and Prevention (CDC) guidelines recommend routine HIV screening in locations including emergency departments. This study evaluates a novel approach to HIV counseling and testing (C&T) in a high-volume inner-city emergency department in terms of the number of patients who can be recruited, tested, test positive, and are linked to care. This prospective evaluation was conducted for 26 months. Noncritically ill or injured patients presenting to an inner-city emergency department were recruited. Patients used a multimedia program that facilitated data entry and viewed previously evaluated HIV counseling videos. Demographic characteristics, risk factors, and sexual history were collected. Data were collected on the number of patients tested, number of HIV-positive patients identified, and number linked to care. Demographic characteristics of the participants were as follows: 48.7% males, mean age 32.6 +/- 11.3, 34.6% Hispanic, and 37.9 % African American. Of the 7109 eligible patients approached, 6214 (87.4%) agreed to be HIV tested. There were 57 newly diagnosed or confirmed HIV-positive patients, representing a seroprevalence of 0.92%. Of those testing positive, 49 (84.2%) were linked to care and had a mean initial CD4 count of 238 cells/mm(3). In conclusion, a video-assisted rapid HIV program in a busy inner-city hospital emergency department can effectively test a high volume of patients and successfully link HIV-positive individuals to care, while providing high-quality education and prevention messages for all those who test.

OBJECTIVES Casual review of existing literature reveals a multitude of individualized approaches to emergency department (ED) HIV testing. Cataloging the operational options of each approach could assist translation by disseminating existing knowledge, endorsing variability as a means to address testing barriers, and laying a foundation for future work in the area of operational models and outcomes investigation. The objective of this study is to provide a detailed account of the various models and operational constructs that have been described for performing HIV testing in EDs. METHODS Systematic review of PUBMED, EMBASE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), and the Web of Science through February 6, 2009 was performed. Three investigators independently reviewed all potential abstracts and identified all studies that met the following criteria for inclusion: original research, performance of HIV testing in an ED in the United States, description of operational methods, and reporting of specific testing outcomes. Each study was independently assessed and data from each were abstracted with standardized instruments. Summary and pooled descriptive statistics were reported by using recently published nomenclature and definitions for ED HIV testing. RESULTS The primary search yielded 947 potential studies, of which 25 (3%) were included in the final analysis. Of the 25 included studies, 13 (52%) reported results using nontargeted screening as the only patient selection method. Most programs reported using voluntary, opt-in consent and separate, signed consent forms. A variety of assays and communication methods were used, but relatively limited outcomes data were reported. CONCLUSION Currently, limited evidence exists to inform HIV testing practices in EDs. There appears to be recent progression toward the use of rapid assays and nontargeted patient selection methods, with the rate at which reports are published in the peer-reviewed literature increasing. Additional research will be required, including controlled clinical trials, more structured program evaluation, and a focus on an expanded profile of outcome measures, to further improve our understanding of which HIV testing methods are most effective in the ED.

Objective: Many of the individuals most at risk for HIV infection (i.e., minority populations, women, adolescents) are also the most marginalized by our health care system. Lacking primary care providers, they rely on the Emergency Department (ED) for their health care needs and education. In this prospective randomized controlled trial, we compared the educational effectiveness of a 15-minute posttest counseling video with the normal practice of a session with an HIV counselor. The study population was composed of ambulatory patients recruited for rapid HIV testing in the ED. Methods: The RAs (research assistants) recruited a convenience sample of stable patients presenting to the walk-in section of an inner-city adult ED for rapid HIV testing. Eligible patients for this study included patients who consented for the rapid HIV test and completed measures on condom intention and condom use self-efficacy. Before receiving their results, participants who consented to be in this study were randomized to either a 15-minute HIV posttest educational video available in English/Spanish or to a posttest educational session with an HIV counselor. Afterwards, both groups completed an assessment tool concerning HIV prevention and transmission. Results: Of the 128 participants, 61 and 67 patients were randomized to the video and counselor groups, respectively. The groups were similar with respect to gender, ethnicity and experience with prior HIV testing. Mean knowledge scores were higher in the video group (76.20% vs. 69.3%; 90% CI for the difference, 2.8, 11.2). As the lower bound of the CI for the difference was higher than the lower equivalence boundary (−5%), we infer that the video was at least as effective as the counselor educational session. Conclusions: The use of an educational counseling video is a valid alternative for providing posttest education and prevention information during the waiting period associated with the 20-minute HIV rapid test. Without disruption in clinical flow, both testing and education can be accomplished in a meaningful way in a busy ED.

The purpose of this study was to examine the results of implementing a rapid counselor-based HIV testing program in community pharmacies. A prospective cross-sectional study was conducted on a convenience sample of clients at five community pharmacies in New York City (NYC). In 294 days of pharmacy testing, 2805 clients were eligible to receive testing, and 2030 individuals agreed to test. The average age was 33±15 years, 41% were male, 59% were Hispanic, 77% had been previously tested for HIV, and 34% were uninsured. HIV incidence was 0.3%, median CD4 cell count was 622.0, and the average age of the newly diagnosed positives was 36.0±13.9 years. Participants were satisfied with a counselor-based rapid HIV testing program in community-based pharmacies.

Studies of data from the 1990s are often cited as evidence of racial and ethnic disparities in pain management. Subsequent evidence supporting this association has not been consistent. The objective was to assess whether there are racial or ethnic disparities in receipt of analgesics for pain from long-bone fractures more recently and in a different region of the United States. We conducted a retrospective chart review of 449 patients. Twenty-three percent (53/235) of Hispanic patients, 31% (41/133) of African American patients, and 26% (21/81) of white patients did not receive analgesics. Compared with white patients, the relative risk of not receiving analgesics was 1.31 (95% confidence interval, 0.74-2.03) for African Americans and 0.90 (95% confidence interval, 0.05-1.47) for Hispanic patients after controlling for age, sex, mechanism, marital status, mode of arrival, fracture reduction, fracture type, disposition, and insurance status. We did not find evidence of racial or ethnic disparities in the management of pain from long-bone fractures.

Objective: To test a model designed to increase willingness of patients presenting to the emergency department off hours to be tested for human immunodeficiency virus (HIV) by using a pretest counseling video as a substitute for face-to-face counseling. Methods: We conducted a randomized controlled trial comparing the rate of testing in patients randomized to receive video counseling with immediate testing (video group) versus standard care, which was referral to counseling and testing the next day (standard referral group). Results: Fifty percent of 805 eligible patients consented to participate in the study, indicating willingness to be tested. The HIV testing rate was higher in the video group 92.6% (187 of 202) than in the standard referral group 4.5% (9 of 202) (difference = 88.1%, 95% confidence interval: 83.5%–92.7%). Thirty percent of 187 patients in the video group who were tested returned for their results; 8 of 9 patients in standard care returned to be tested and to get their results. Conclusion: Half of the patients who were solicited for HIV testing agreed to be tested. When testing was immediate the patient was more likely to have the test completed.
