Preventive care in the emergency department: should emergency departments conduct routine HIV screening? a systematic review

Patients' Perspectives on Emergency Department COVID-19 Vaccination and Vaccination Messaging Through Randomized Vignettes

Objectives:

Emergency departments (EDs) could play an important role in the COVID-19 pandemic response by reaching patients who would otherwise not seek vaccination in the community. Prior to expanding COVID-19 vaccination to the acute care setting, we assessed ED patients’ COVID-19 vaccine status, perspectives, and hypothetical receptivity to ED-based vaccination.

Methods:

From January 11 through March 31, 2021, we conducted a multisite (Albany Medical Center, Boston Medical Center, Buffalo General Hospital, University of Cincinnati Medical Center, and Upstate Medical Center), cross-sectional survey of ED patients, with embedded randomization for participants to receive 1 of 4 vignette vaccination messages (simple opt-in message, recommendation by the hospital, community-oriented message, and acknowledgment of vaccine hesitancy). Main outcomes included COVID-19 vaccination status, prior intention to be vaccinated, and receptivity to randomized hypothetical vignette messages.

Results:

Of 610 participants, 122 (20.0%) were vaccinated, 234 (38.4%) had prior intent to be vaccinated, 111 (18.2%) were unsure as to prior intent, and 143 (23.4%) had no prior intent to be vaccinated. Vaccine hesitancy (participants who were vaccine unsure or did not intend to receive the vaccine) was associated with the following: age <45 years, female, non-Hispanic Black, no primary health care, and no prior influenza vaccination. Overall, 364 of 565 (64.4%; 95% CI, 60.3%-68.4%) were willing to accept a hypothetical vaccination in the ED. Among participants with prior vaccine hesitancy, a simple opt-in message resulted in the highest acceptance rates to hypothetical vaccination (39.7%; 95% CI, 27.6%-52.8%).

Conclusions:

EDs have appropriate patient populations to initiate COVID-19 vaccination programs as a supplement to community efforts. A simple opt-in approach may offer the best messaging to reach vaccine-hesitant ED patients.

Assessing attitudes to ED-based HIV testing: Development of a short-structured survey instrument

INTRODUCTION

Emergency Department (ED)-based HIV counseling and testing (HCT) has had a significant impact on improving rates of HIV diagnosis and linkage to care. Unfortunately, expansion of this strategy to low- and middle-income countries has been limited. Successful implementation of ED-based HCT is dependent on patient and provider acceptance of the intervention, and their attitudes and pre-existing biases towards the disease. This study sought to develop validated survey instruments to assess attitudes towards ED-based HCT.

METHODS

This cross-sectional study surveyed patients and providers in three EDs in the Eastern Cape province, South Africa. A convenience sample of patients and providers in the ED were surveyed. Exploratory factor analysis was conducted using questions on attitudes to HIV testing to develop validated survey instruments. An ANOVA test assessed variance in attitudes towards HCT based on demographic variables collected.

RESULTS

A total of 104 patient and 132 provider surveys were completed. Exploratory factor analysis resulted in a 17- and 7-question attitudes survey for patients and providers, respectively. Overall, 92.3% of patients and 70.7% of providers supported ED-based HCT, however, both groups displayed only mildly positive attitudes. Questions representing 'confidentiality' and 'stigma around HIV testing' had the least positive influence on patients' overall attitudes. Questions representing 'comfort with HIV testing' had the least positive influence on providers' overall attitudes.

CONCLUSION

Our study demonstrated ED patients and providers are generally supportive of ED-based HCT. A validated survey instrument was able to provide a standardized approach to identify barriers to HCT implementation in an ED setting, across contexts. For successful implementation, behavioral interventions must focus on strengthening patient beliefs around confidentiality and the consent process, and providers' comfort levels with providing HIV testing services in the ED.

Prevalence of undiagnosed HIV, hepatitis B, and hepatitis C among patients in an Indian emergency department

OBJECTIVES

HIV, hepatitis B, and hepatitis C remain significant causes of morbidity and mortality in low resource settings. Emergency department (ED)-based screening has proven effective in decreasing the spread of undiagnosed disease, although such programs are rare in low-middle income countries.

METHODS

A prospective, cross sectional study of all adult patients presenting to the ED in a 600-bed teaching hospital in Tamil Nadu, India. This study used an opt-in strategy in which patients were offered testing at the end of their ED visit. Costs of testing were paid out of pocket by patients. Patients with known HIV, hepatitis B, or hepatitis C were excluded from the study.

RESULTS

During the study period 26,465 patients presented to the ED, and 18,286 patients consented to participate (68.9%). Among the 18,286 patients tested, 174 were positive for either HIV (39, 0.21%), hepatitis C (52, 0.28%), or hepatitis B (83, 0.45%). Three patients tested positive for both HIV and hepatitis C, and 1 patient tested positive for both HIV and hepatitis B. A total of 69.2% of patients with HIV, 61.2% of patients with hepatitis B, and 83% of patients with hepatitis C presented for reasons unrelated to their underlying diagnosis.

CONCLUSION

Although limited to only 1 hospital in southern India, this study represents the largest ED-based screening program for HIV, hepatitis B, and hepatitis C ever conducted in India or any other low-middle income countries. The majority of patients presented for reasons unrelated to their underlying diagnosis. Future research is needed on implementation strategies, cost feasibility, and linkage to care.

Testing for HIV infection in the emergency departments of 2 hospitals in the Southeastern United States

BACKGROUND

In 2006, the Centers for Disease Control and Prevention (CDC) recommended non-targeted, opt-out HIV screening in all healthcare settings, including emergency departments (EDs). Multiple HIV testing programs have been implemented in EDs across the United States with varying designs and testing platforms. We report findings from a free, non-targeted, rapid HIV testing program in 2 EDs in the Southeastern United States.

METHODS

From 2008 to 2012, adults ≥18 years of age were offered free rapid HIV testing using an oral swab test (OraQuick ADVANCE Rapid HIV-1/2 antibody test) in the EDs of a large academic medical center and an affiliated community hospital in Durham, North Carolina.

RESULTS

In total, 5443 ED patients were offered HIV testing. The overall acceptance rate was 66.9% (3639/5443). Younger persons were significantly more likely to accept testing (78.2% for 18-29 years old vs 67.1% for ≥30 years old; P < 0.001) as were Black participants (72.6% Black vs 66.5% White; P < 0.001). Acceptance rates improved significantly after opt-out oral consent replaced written consent (71.3% vs 63.1%; P < 0.001). Seven new HIV diagnoses were confirmed during the testing program, resulting in a seropositivity rate of 0.19% (7/3639). There were 8 false-positive rapid oral HIV tests (positive predictive value = 46.7%).

CONCLUSIONS

Although the number of new HIV diagnoses was low, implementation of this rapid, non-targeted ED screening program was feasible with high acceptance rates, particularly after introducing the opt-out oral consent approach.

Patient acceptance of HIV testing services in rural emergency departments in South Africa

Background

South Africa faces the highest burden of HIV infection globally. The National Strategic Plan on HIV recommends provider-initiated HIV counselling and testing (HCT) in all healthcare facilities. However, HIV continues to overwhelm the healthcare system. Emergency department (ED)-based HCT could address unmet testing needs.

Objectives

This study examines the reasons for accepting or declining HCT in South African EDs to inform the development of HCT implementation strategies.

Method

We conducted a prospective observational study in two rural EDs, from June to September 2017. Patients presenting to the ED were systematically approached and offered a point-of-care test in accordance with national guidelines. Patients demographics, presenting compaint, medical history and reasons for accepting/declining testing, were recorded. A pooled analysis is presented.

Results

Across sites, 2074 adult, non-critical patients in the ED were approached; 1880 were enrolled in the study. Of those enrolled, 19.7% had a previously known positive diagnosis, and 80.3% were unaware of their HIV status. Of those unaware, 90% patients accepted and 10% declined testing. The primary reasons for declining testing were ‘does not want to know status’ (37.6%), ‘in too much pain’ (34%) and ‘does not believe they are at risk’ (19.9%).

Conclusions

Despite national guidelines, a high proportion of individuals remain undiagnosed, of which a majority are young men. Our study demonstrated high patient acceptance of ED-based HCT. There is a need for investment and innovation regarding effective pain management and confidential service delivery to address patient barriers. Findings support a routine, non-targeted HCT strategy in EDs.

A systematic review of emergency department based HIV testing and linkage to care initiatives in low resource settings

INTRODUCTION

Only 45% of people currently living with HIV infection in sub-Saharan Africa are aware of their HIV status. Unmet testing needs may be addressed by utilizing the Emergency Department (ED) as an innovative testing venue in low and middle-income countries (LMICs). The purpose of this review is to examine the burden of HIV infection described in EDs in LMICs, with a focus on summarizing the implementation of various ED-based HIV testing strategies.

METHODOLOGY AND RESULTS

We performed a systematic review of Pubmed, Embase, Scopus, Web of Science and the Cochrane Library on June 12, 2016. A three-concept search was employed with emergency medicine (e.g., Emergency department, emergency medical services), HIV/AIDS (e.g., human immunodeficiency virus, acquired immunodeficiency syndrome), and LMIC terms (e.g., developing country, under developed countries, specific country names). The search returned 2026 unique articles. Of these, thirteen met inclusion criteria and were included in the final review. There was a large variation in the reported prevalence of HIV infection in the ED population ranging from to 2.14% in India to 43.3% in Uganda. The proportion HIV positive patients with previously undiagnosed infection ranged from 90% to 65.22%.

CONCLUSION

In the United States ED-based HIV testing strategies have been front and center at curbing the HIV epidemic. The limited number of ED-based studies we observed in this study may represent the paucity of HIV testing in this venue in LMICs. All of the studies in this review demonstrated a high prevalence of HIV infection in the ED and an extraordinarily high percentage of previously undiagnosed HIV infection. Although the numbers of published reports are few, these diverse studies imply that in HIV endemic low resource settings EDs carry a large burden of undiagnosed HIV infections and may offer a unique testing venue.

Attitudes and barriers towards HIV screening: A qualitative study of people living with HIV/AIDS (PLWHA) in Malaysia

BACKGROUND

Understanding patients' perspective towards HIV screening in Malaysia is pivotal to explore challenges faced by these individuals. This would be beneficial for developing local plans to improve the health-seeking behaviours among population at risk of HIV/AIDS.

METHODS

A qualitative research methodology was adopted to explore HIV/AIDS patients' views about disease screening. A semi-structured interview guide was used for in-depth patient interviews. All interviews were audio-recorded and were subjected to a standard content analysis framework for data analysis.

RESULTS

Most patients were positive about screening and the value of knowing about their status early. However, fear of social stigma, discrimination, lack of support system and lack of public understanding were identified as major concerns affecting their willingness to be screened. They were concerned about mandatory screening being implemented without improvement in support system and public education.

CONCLUSIONS

Reluctance to seek HIV screening is an important factor contributing to transmission in developing countries. In the Malaysian context, efforts should be made to strengthen screening strategies especially in the most-at-risk populations to monitor the epidemic and target prevention strategies.

PRACTICE IMPLICATIONS

In a multicultural context, HIV preventive strategies must include disease awareness, including measure to tackle barriers towards screening.

HIV Prevention and Treatment: The Evolving Role of the Emergency Department

Historically, the role of the emergency physician in HIV care has been constrained to treating sick patients with opportunistic infections and postexposure prophylaxis for occupational exposures. However, advances in HIV care have led to medications that have substantially fewer issues with toxicity and resistance, opening up an exciting new opportunity for emergency physicians to participate in treating the HIV virus itself. With this new role, it is crucial that emergency physicians be familiar with the advances in testing and medications for HIV prevention and treatment. To our knowledge, to date there has not yet been an article addressing this expansion of practice. We have compiled a summary of what the emergency physician needs to know, including misconceptions associated with antiretroviral therapy, medication complexity, toxicity, resistance, and usability. Additionally, we review potential indications for prescribing these drugs in the emergency department, including the role of the emergency physician in postexposure prophylaxis, preexposure prophylaxis, and treatment of acute HIV, as well as how emergency physicians can engage with chronic HIV infection.

Scaling Up HIV Testing in an Academic Emergency Department: An Integrated Testing Model with Rapid Fourth-Generation and Point-of-Care Testing

OBJECTIVE

We evaluated two approaches for implementing routine HIV screening in an inner-city, academic emergency department (ED). These approaches differed by staffing model and type of HIV testing technology used. The programmatic outcomes assessed included the total number of tests performed, proportion of newly identified HIV-positive patients, and proportion of newly diagnosed individuals who were linked to care.

METHODS

This study examined specific outcomes for two distinct, successive approaches to implementing HIV screening in an inner-city, academic ED, from July 2012 through June 2013 (Program One), and from August 2013 through July 2014 (Program Two). Program One used a supplementary staff-only HIV testing model with point-of-care (POC) oral testing. Program Two used a triage-integrated, nurse-driven HIV testing model with fourth-generation blood and POC testing, and an expedited linkage-to-care process.

RESULTS

During Program One, 6,832 eligible patients were tested for HIV with a rapid POC oral HIV test. Sixteen patients (0.2%) were newly diagnosed with HIV, of whom 13 were successfully linked to care. During Program Two, 8,233 eligible patients were tested for HIV, of whom 3,124 (38.0%) received a blood test and 5,109 (62.0%) received a rapid POC test. Of all patients tested in Program Two, 29 (0.4%) were newly diagnosed with HIV, four of whom had acute infections and 27 of whom were successfully linked to care. We found a statistically significant difference in the proportion of the eligible population tested-8,233 of 49,697 (16.6%) in Program Two and 6,832 of 46,818 (14.6%) in Program One. These differences from Program One to Program Two corresponded to increases in testing volume (n=1,401 tests), number of patients newly diagnosed with HIV (n=13), and proportion of patients successfully linked to care (from 81.0% to 93.0%).

CONCLUSION

Integrating HIV screening into the standard triage workflow resulted in a higher proportion of ED patients being tested for HIV as compared with the supplementary staff-only HIV testing model. New rapid fourth-generation testing technology allowed the identification of acute HIV infection and same-visit confirmation of a positive diagnosis.

The acceptability of incorporating a youth smoking prevention intervention in the pediatric emergency department

The pediatric emergency department (PED) is under-utilized as a setting in which to provide tobacco prevention interventions for at-risk children. We sought to determine the acceptability and feasibility of incorporating a brief, parental tobacco prevention intervention to 520 parents during the PED visit. Mean age (SD) of parents and children was 38.6 (7.1) and 11.5 (1.1), respectively; 47% of children were female; 45% were African American; 36% of parents had an annual income less than $25,000; 28.8% of parents were current smokers. Over 90% of parents said the intervention provided "useful" and "easy to understand" information and 97% of practitioners said it did not "interfere with clinical care." Given the high prevalence of parental smoking in the PED, there is a high likelihood that their children will initiate smoking in the future. Thus, the use of the PED as a venue to providing tobacco prevention interventions warrants further evaluation.

Point-of-care tests for sexually transmissible infections: what do 'end users' want?

BACKGROUND

Clinicians and developers identify sensitivity as an important quality in a point-of-care test (POCT) for sexually transmissible infections (STIs). Little information exists regarding what patients want for STI POCTs.

METHODS

A qualitative study, encompassing five focus groups among attendees of STI and adolescent health centres in Baltimore, Maryland, and Cincinnati, Ohio, were conducted between March 2008 and April 2009. Discussion topics included advantages and disadvantages of having a POCT, perceived barriers to using POCTs in the clinic setting and at home, priorities for the development of new POCTs for STIs, and envisioned characteristics of an ideal POCT. All discussions were recorded and transcribed. A qualitative content analysis was performed to examine frequencies or patterns of recurring codes, which were regrouped and indexed to identify salient themes.

RESULTS

Patients attending STI and adolescent outpatient clinics are in favour of diagnostic tests that are rapid, easy to read and simple to use. Home testing options for POCTs were acceptable and provided better confidentiality, privacy and convenience, but clinic-based POCTs were also acceptable because they offer definitive results and ensure immediate treatment. Barriers to home POCTs centred on cost and the ability to read and perform the test correctly at home. Opinions did not differ by patient ethnicity, except that Hispanic participants questioned the reliability of home test results, wanted high sensitivity and desired bilingual instructions.

CONCLUSIONS

Patients attending STI and adolescent medical centres are in favour of STI POCTs if they are affordable, rapid, easy to read and simple to use.

A five-year self-sustainability analysis of nurse-administered HIV rapid testing in Veterans Affairs primary care

In 2008, nurse-administered HIV oral rapid testing (RT) was introduced at the Veterans Affairs Primary Care Clinic in Downtown Los Angeles. Analysis at five years revealed variable yet increasing rates of HIV RT at that facility despite the fact that no post-launch support was provided by the implementation team. Qualitative interviews among stakeholders conducted at five years revealed the pre-existing implementation practices endemic to this clinic that facilitated this unprecedented success (e.g. history of positive quality improvement implementations, leadership support, clinician involvement at each step of the process to facilitate empowerment, ownership and feasible customisation of the implementation, cohesive communication among clinicians and leadership, training, efficient supply pathway, progressive performance feedback and ongoing encouragement).

Addressing unmet need for HIV testing in emergency care settings: a role for computer-facilitated rapid HIV testing?

HIV testing in emergency departments (EDs) remains underutilized. The authors evaluated a computer tool to facilitate rapid HIV testing in an urban ED. Randomly assigned nonacute adult ED patients were randomly assigned to a computer tool (CARE) and rapid HIV testing before a standard visit (n = 258) or to a standard visit (n = 259) with chart access. The authors assessed intervention acceptability and compared noted HIV risks. Participants were 56% nonWhite and 58% male; median age was 37 years. In the CARE arm, nearly all (251/258) of the patients completed the session and received HIV results; four declined to consent to the test. HIV risks were reported by 54% of users; one participant was confirmed HIV-positive, and two were confirmed false-positive (seroprevalence 0.4%, 95% CI [0.01, 2.2]). Half (55%) of the patients preferred computerized rather than face-to-face counseling for future HIV testing. In the standard arm, one HIV test and two referrals for testing occurred. Computer-facilitated HIV testing appears acceptable to ED patients. Future research should assess cost-effectiveness compared with staff-delivered approaches.

Providers' perceptions of the factors influencing the implementation of the New York State mandatory HIV testing law in two Urban academic emergency departments

OBJECTIVES

Of the 1.1 million people in the United States infected with human immunodeficiency virus (HIV), more than 20% are unaware of their infection. To increase early diagnosis and treatment, New York State recently passed legislation mandating that HIV testing be offered to all patients, ages 13 to 64 years, receiving health care services. Implementation of this legislation is complex, especially in the emergency department (ED). This study explores ED providers' perceptions of the factors affecting the implementation of the law.

METHODS

The authors conducted six focus group sessions and three in-depth interviews with ED health care providers from two New York City teaching hospitals. Sessions were audiotaped and transcribed. Data were coded and summarized thematically through an iterative process after each session.

RESULTS

A total of 49 providers participated and data saturation was achieved. Six factors were identified that predispose a provider to offer an HIV test: 1) self-efficacy, 2) behavioral intention, 3) the testing process, 4) provider knowledge of the legislation, 5) type of HIV test, and 6) follow-up procedures. Five factors were identified that enable providers to offer an HIV test: 1) resources related to time, 2) space, 3) staff, 4) type of test, and 5) timing of the offer. Improving access to HIV testing, linkage to care, and public health were all key factors in reinforcing providers' desire to offer HIV tests. Concerns regarding overall cost saving and coverage for the test were indicated as barriers that needed to be resolved to reinforce the providers to offer an HIV test.

CONCLUSIONS

Understanding the factors influencing the practice of ED providers charged with carrying out this mandate is critical. Despite earlier research that indicated that offering HIV testing to ED patients is largely influenced by cost, this study found additional factors that are important to consider to effectively implementing HIV testing in the ED.

Rapid human immunodeficiency virus testing in the pediatric emergency department: a national survey of attitudes among pediatric emergency practitioners

OBJECTIVE

Human immunodeficiency virus (HIV) continues to be a significant public health concern for adolescents and young adults. Since 2006, the Centers for Disease Control and Prevention has recommended more aggressive routine screening for HIV for patients presenting to the emergency department (ED). Our objectives were to design and validate a survey of physician barriers toward the use of rapid HIV testing in the pediatric ED and then to use this validated tool to conduct a national survey of pediatric emergency practitioners' attitudes toward rapid HIV testing in the ED.

METHODS

Survey design and initial validation steps were conducted with a panel of health care practitioners familiar to HIV testing. Several variables were identified as possible barriers toward rapid HIV testing. The survey was sent via electronic software to a national sample of pediatric emergency practitioners over 2 listservs. The previously identified variables were evaluated by factor analysis for internal consistency and homogeneity, and confirmatory factor analysis was conducted via promax and varimax rotation. All factor analyses were conducted using Stata software. Once the validation was complete, the surveys were sent to groups of pediatric emergency practitioners who had previously identified as having rapid HIV testing available in their EDs. Standard descriptive statistics were used, and group differences were evaluated with t test and χ(2) test.

RESULTS

Four factors were identified during the validation process as being the most important barriers for rapid HIV testing in the pediatric ED: self efficacy, familiarity, external barriers, and a previously unidentified factor, which we interpreted as related to barriers to the specific environment of one's own ED. A total of 80 participants returned the final, validated survey. The participants came from 9 different pediatric emergency medicine groups (5 in areas of low rates of HIV infection, 4 in areas of high rates of HIV infection). Self-reported rates of testing were not different based on HIV infection rate in the community or the respondent's level of training. High testing was more common when a guideline was reported (39%) than when it was not (13.3%; difference, 25.7%; 95% confidence interval, 2.9%-48.5%). Of the 4 factors identified, we found statistically significant differences in scores on all 4 factors between high versus low testers, with high testers disagreeing more strongly with the various barrier questions proposed. We found no difference in the factor scores between areas of high versus low HIV infection rates.

CONCLUSIONS

Our results suggest that several factors related to perceived provider barriers are associated with rates of HIV testing in the ED and that personal factors (eg, level of training) and community HIV prevalence were not associated with rates of testing. Our results confirm what has been speculated by numerous authors and provide data to inform efforts to improve compliance with national recommendations for increased testing.

World Health Assembly Resolution 60.22 and its importance as a health care policy tool for improving emergency care access and availability globally

The recent adoption of World Health Assembly Resolution 60.22, titled "Health Systems: Emergency Care Systems," has established an important health care policy tool for improving emergency care access and availability globally. The resolution highlights the role that strengthened emergency care systems can play in reducing the increasing burden of disease from acute illness and injury in populations across the socioeconomic spectrum and calls on governments and the World Health Organization to take specific and concrete actions to make this happen. This resolution constitutes recognition by the World Health Assembly of the growing public health role of emergency care systems and is the highest level of international attention ever devoted to emergency care systems worldwide. Emergency care systems for secondary prevention of acute illnesses and injury remain inadequately developed in many low- and middle-income countries, despite evidence that basic strategies for improving emergency care systems can reduce preventable mortality and morbidity and can in many cases also be cost-effective. Emergency care providers and their professional organizations have used their comprehensive expertise to strengthen emergency care systems worldwide through the development of tools for emergency medicine education, systems assessment, quality improvement, and evidence-based clinical practice. World Health Assembly 60.22 represents a unique opportunity for emergency care providers and other advocates for improved emergency care to engage with national and local health care officials and policymakers, as well as with the World Health Organization, and leverage the expertise within the international emergency medicine community to make substantial improvements in emergency care delivery in places where it is most needed.

Dog bite prevention: an assessment of child knowledge

OBJECTIVES

To determine what children know about preventing dog bites and to identify parental desires for dog bite prevention education.

STUDY DESIGN

This cross-sectional study sampled 5- to 15-year-olds and their parents/guardians presenting to a pediatric emergency department with nonurgent complaints or dog bites. The parent/guardian-child pairs completed surveys and knowledge-based simulated scenario tests developed on the basis of American Academy of Pediatrics and Centers for Disease Control and Prevention dog bite prevention recommendations. Regression analyses modeled knowledge test scores and probability of passing; a passing score was ≥11 of 14 questions.

RESULTS

Of 300 parent/guardian-child pairs, 43% of children failed the knowledge test. Older children had higher odds of passing the knowledge test than younger children, as did children with white parents vs those with nonwhite parents. No associations were found between knowledge scores and other sociodemographic or experiential factors. More than 70% of children had never received dog bite prevention education, although 88% of parents desired it.

CONCLUSIONS

Dog bites are preventable injures that disproportionately affect children. Dog bite prevention knowledge in our sample was poor, particularly among younger children and children with nonwhite parents. Formal dog bite prevention education is warranted and welcomed by a majority of parents.

A comparison of patient and staff attitudes about emergency department-based HIV testing in 2 urban hospitals

OBJECTIVE

This study compares and contrasts emergency department (ED) patient and staff attitudes towards ED-based HIV testing in 2 major hospitals in a single city, with an attempt to answer the following: Should routine ED-based HIV testing be offered? If so, who should be responsible for disclosing HIV test results? And what barriers might prevent ED-based HIV testing?

METHODS

Paper-based surveys were presented to a convenience sample of ED patients and staff at 2 urban, academic, tertiary care hospitals between December 2007 and June 2009. Descriptive statistics were derived with SAS and MicroSoft Excel. Data are reported in percentages, fractions, and graphs.

RESULTS

A total of 457 patients and 85 staff completed the surveys. The majority of patients favor ED-based HIV testing. Only a minority of ED staff support ED-based HIV testing. In both hospitals, patients prefer to have HIV test results delivered by a physician. This was true for both positive and negative results. However, only about one third of attending physicians feel comfortable disclosing a positive HIV test result. Patients and staff both view privacy and confidentiality as significant barriers to ED-based HIV testing.

CONCLUSION

Although ED patients are overwhelmingly in favor of ED-based HIV testing, the staff is not. Patients and staff agree that physicians should deliver HIV test results to patients, but a significant number of physicians are not comfortable doing so. Historical barriers continue to hinder ED-based HIV testing programs.

Public health and clinical impact of increasing emergency department-based HIV testing: perspectives from the 2007 conference of the National Emergency Department HIV Testing Consortium

OBJECTIVE

Understanding perceived benefits and disadvantages of HIV testing in emergency departments (EDs) is imperative to overcoming barriers to implementation. We codify those domains of public health and clinical care most affected by implementing HIV testing in EDs, as determined by expert opinion.

METHODS

Opinions were systematically collected from attendees of the 2007 National ED HIV Testing Consortium meeting. Structured evaluation of strengths, weaknesses, opportunities, and threats analysis was conducted to assess the impact of ED-based HIV testing on public health. A modified Delphi method was used to assess the impact of ED-based HIV testing on clinical care from both individual patient and individual provider perspectives.

RESULTS

Opinions were provided by 98 experts representing 42 academic and nonacademic institutions. Factors most frequently perceived to affect public health were (strengths) high volume of ED visits and high prevalence of HIV, (weaknesses) undue burden on EDs, (opportunities) reduction of HIV stigma, and (threats) lack of resources in EDs. Diagnostic testing and screening for HIV were considered to have a favorable impact on ED clinical care from both individual patient and individual provider perspectives; however, negative test results were not perceived to have any benefit from the provider's perspective. The need for HIV counseling in the ED was considered to have a negative impact on clinical care from the provider's perspective.

CONCLUSION

Experts in ED-based HIV testing perceived expanded ED HIV testing to have beneficial impacts for both the public health and individual clinical care; however, limited resources were frequently cited as a possible impediment. Many issues must be resolved through further study, education, and policy changes if the full potential of HIV testing in EDs is to be realized.

Will patients "opt in" to perform their own rapid HIV test in the emergency department?

OBJECTIVE

We evaluate the feasibility and accuracy of existing point-of-care HIV tests performed by an untrained patient compared with the routinely used HIV point-of-care test offered to patients in 2 urban emergency departments (EDs).

METHODS

From April 2008 through December 2009, patients who had completed a standard HIV oral fluid test performed by a trained health care professional and who were unaware of their results were recruited to perform a rapid point-of-care HIV test. Patients were given a choice of the oral fluid or the fingerstick blood point-of-care test. Evaluation of acceptability to perform the mechanics of the test was accessed by questionnaire. For the "self-test," the participant obtained his or her own sample and performed the test. The patient's results were compared with standard oral fluid results obtained by the health care professional.

RESULTS

Overall, 478 of 564 (85%) patients receiving a standard oral fluid HIV test volunteered, with a mean age of 38 to 39 years. Ninety-one percent of participants chose oral fluid and 9% chose blood (P<.05). Self-test results were 99.6% concordant with health care professionals' test results. For the self-testers, 94% of oral fluid testers and 84.4% of blood testers reported trusting the self-administered test result "very much." Furthermore, 95.6% of the oral fluid group and 93.3% of the blood group would "probably" or "definitely" perform a test at home, if available.

CONCLUSION

This study demonstrated that a significant proportion of patients offered a self-HIV point-of-care test volunteered and preferred using oral fluid. Patients' results agreed with standard HIV point-of-care results. The majority of participants trusted their results and would perform a point-of-care HIV test at home, given the opportunity.

Who are California's late HIV testers? An analysis of state AIDS surveillance data, 2000-2006

OBJECTIVES

Late HIV testing leads to preventable, severe clinical and public health outcomes. California, lacking a mature HIV surveillance system, has been excluded from documented analyses of late HIV testers in the United States. We identified factors associated with late HIV testing in the California AIDS surveillance data to inform programs of HIV testing and access to treatment.

METHODS

We analyzed data from California AIDS cases diagnosed between 2000 and 2006 and reported through November 1, 2007. Late testers were people diagnosed with HIV within 12 months before their AIDS diagnosis. We identified factors significantly associated with late HIV testing using multivariable logistic regression.

RESULTS

Among 28,382 AIDS cases, 61.2% were late HIV testers. Late testing was significantly associated with those > or = 35 years of age, heterosexual contact or unknown/other reported transmission risk, and being born outside of the U.S. When further classified by country of birth, people born in Mexico were most likely to be HIV late testers who progressed to AIDS.

CONCLUSIONS

Our findings support wider implementation of opt-out HIV testing and HIV testing based in emergency departments. Services for HIV testing and treatment should be inclusive of all populations, but especially targeted to populations that may have more limited access.

Educational effectiveness of an HIV pretest video for adolescents: a randomized controlled trial

OBJECTIVE

The goal of this study was to compare the effectiveness of a youth-friendly HIV video with in-person counseling in conveying HIV knowledge and obtaining consent for HIV testing among adolescent patients of an urban emergency department.

METHODS

A 2-armed, randomized controlled trial was conducted on a convenience sample of 200 stable, sexually active people aged 15 to 21 years in an urban emergency department. Participants in both the in-person counseling group and the video intervention group completed preintervention and postintervention HIV knowledge measures. HIV knowledge was the primary outcome measure, and consent for HIV testing was the secondary outcome. Characteristics associated with voluntary HIV testing were identified.

RESULTS

Of 333 eligible people, 200 agreed to participate. There was no difference in preintervention HIV knowledge scores between groups. Mean postintervention knowledge scores differed significantly between the video (78.5% correct) and the counselor (66.3% correct) (P < 0.01) groups. Overall, 51% of the video group accepted HIV testing compared with 22% in the control group (P < .01). Watching the video (OR: 3.6 [95% CI: 1.8-7.2]), being female (OR: 2.1 [95% CI: 1.0-4.2]), engaging in oral sex (OR: 2.8 [95% CI: 1.4-5.9]), and being older than 18 years (OR: 3.8 [95% CI: 1.8-7.8]) were all positively associated with testing.

CONCLUSIONS

A youth-friendly HIV educational video improved adolescents' HIV knowledge and increased their participation in HIV testing more than in-person counseling. video-based HIV counseling can perform as well or better than in-person counseling for adolescents in the ED.

High-volume rapid HIV testing in an urban emergency department

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.

Rapid HIV testing program implementation: lessons from the emergency department

BACKGROUND

The US Centers for Disease Control and Prevention (CDC) guidelines and the World Health Organization (WHO) both recommend HIV testing in health-care settings. However, neither organization provides prescriptive details regarding how these recommendations should be adapted into clinical practice in an emergency department.

METHODS

We have implemented an HIV-testing program in the ED of a major academic medical center within the scope of the Universal Screening for HIV Infection in the Emergency Room (USHER) Trial-a randomized clinical trial evaluating the feasibility and cost-effectiveness of HIV screening in this setting.

RESULTS AND CONCLUSION

Drawing on our collective experiences in establishing programs domestically and internationally, we offer a practical framework of lessons learned so that others poised to embark on such HIV testing programs may benefit from our experiences.

Emergency department patient perceptions and preferences on opt-in rapid HIV screening program components

The aim of this investigation was to assess emergency department (ED) patients' perceptions and preferences about an opt-in, universal, rapid HIV screening program and identify patient groups who expressed stronger beliefs about components of the testing program. From July 2005 to July 2006, ED patients in the opt-in, universal, rapid HIV screening program were interviewed in person. Multivariable regression models were used to compare participants on their beliefs about the program components. Of the 561 participants, 62.0% had previously been tested for HIV. The majority of participants (58.8%) believed the rapid and standard/conventional HIV tests to be equally accurate, 27.7% believed the rapid test to be less or much less accurate, and 8.7% believed the rapid test to be more or much more accurate. Almost two-thirds (65.1%) favored having a rapid instead of a standard/conventional HIV test, 94.6% wanted the test results within one hour, and 61.3% would be likely or very likely to undergo testing in the ED if it prolonged their ED visit. Almost all (92.5%) believed that their medical care was "not at all" delayed because of being tested, 94.1% believed that testing did "not at all" divert attention from the reason for their ED visit, and 80.9% thought that testing in the ED was "not at all" stressful. In multivariable logistic regression models, males and those with more than 12 years of formal education showed greater concerns about the rapid HIV test's accuracy. Hispanic/Latinos, participants with governmental insurance, and those previously HIV tested were more apt to be screened for HIV even if testing delayed their ED departure. Overall, participants were highly accepting of the components of this opt-in rapid HIV screening program. However, concerns regarding the accuracy of the rapid HIV test might limit test acceptance and should be addressed during pre-test information procedures.

A randomized control trial evaluating the educational effectiveness of a rapid HIV posttest counseling video

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.

Prevalence and correlates of unknown HIV infection among patients seeking care in a public hospital emergency department

OBJECTIVES

Screening for human immunodeficiency virus (HIV) infection in the emergency department (ED) has been proposed as an effective approach to increase early HIV diagnosis. To evaluate the potential for the implementation of routine screening, we determined the prevalence of unknown HIV infection among patients being seen in an urban public hospital ED.

METHODS

We conducted a cross-sectional study among patients presenting to the San Francisco General Hospital's ED during March 2007. We reviewed patients' medical records to determine HIV infection status. In patients with unknown or negative HIV-infection status, we tested de-identified remnant blood specimens by HIV-antibody and nucleic-acid assays. We used a sensitive/less sensitive testing algorithm to determine the duration of HIV infection.

RESULTS

During the study period, 1,820 patients had blood collected for clinical evaluation. Of those patients, 146 (8.0%) were known to be HIV-infected. Among the remaining 1,674 patients with unknown HIV-infection status, HIV-infection prevalence was 0.9% (15 of 1,674, 95% confidence interval [CI] 0.55, 1.47). In addition, one case of acute HIV infection (HIV-antibody negative, HIV RNA detected) was identified. Patients with unknown HIV infection vs. those who were uninfected were more likely to be homeless (odds ratio [OR] = 3.89, 95% CI 1.32, 11.45, p<0.05) and 18 to 30 years of age (OR=3.15, 95% CI 1.03, 9.61, p<0.05).

CONCLUSIONS

In a sample of patients visiting a county ED, the relative prevalence of unknown HIV infection (10%) was modest and less than national estimates (25%). Acutely HIV-infected patients might account for a significant proportion of those with unknown HIV infection in an ED setting.

Patient perceptions and acceptance of routine emergency department HIV testing

OBJECTIVES

We report on the rates of patient acceptance and their perceptions of routine emergency department (ED) human immunodeficiency virus (HIV) testing in a high-prevalence area.

METHODS

We analyzed the race/ethnicity of patients who either accepted or declined a routine HIV test that was offered to all patients in the ED of a large academic center. We also distributed a patient perception survey about ED HIV testing.

RESULTS

During the study period, an HIV screening test was offered to 9,826 patients. Of these, 5,232 patients (53%) accepted the test. The acceptance rate of HIV testing was highest among African American patients (55%), followed by 52% for white, 50% for Hispanic, and 42% for Asian patients. A total of 1,519 completed surveys were returned for analysis. The most common reasons for declining a test were that patients did not perceive themselves to be at risk for HIV (49%) or they had recently been tested for HIV (18%). Overall, 84% of patients stated they would recommend to a friend to get an HIV test in the ED. When analyzed by ethnicity, 89% of African American patients stated they would recommend to a friend to get an HIV test if the friend went to the ED, but only 74% of white patients would do so.

CONCLUSIONS

The Centers for Disease Control and Prevention's 2006 recommendations on HIV screening are well accepted by the target populations. Further work at explaining the risk of HIV infection to ED patients should be undertaken and may boost the acceptance rate of ED HIV screening.

Video as an effective method to deliver pretest information for rapid human immunodeficiency testing

OBJECTIVES

Video-based delivery of human immunodeficiency virus (HIV) pretest information might assist in streamlining HIV screening and testing efforts in the emergency department (ED). The objectives of this study were to determine if the video "Do you know about rapid HIV testing?" is an acceptable alternative to an in-person information session on rapid HIV pretest information, in regard to comprehension of rapid HIV pretest fundamentals, and to identify patients who might have difficulties in comprehending pretest information.

METHODS

This was a noninferiority trial of 574 participants in an ED opt-in rapid HIV screening program who were randomly assigned to receive identical pretest information from either an animated and live-action 9.5-minute video or an in-person information session. Pretest information comprehension was assessed using a questionnaire. The video would be accepted as not inferior to the in-person information session if the 95% confidence interval (CI) of the difference (Delta) in mean scores on the questionnaire between the two information groups was less than a 10% decrease in the in-person information session arm's mean score. Linear regression models were constructed to identify patients with lower mean scores based upon study arm assignment, demographic characteristics, and history of prior HIV testing.

RESULTS

The questionnaire mean scores were 20.1 (95% CI = 19.7 to 20.5) for the video arm and 20.8 (95% CI = 20.4 to 21.2) for the in-person information session arm. The difference in mean scores compared to the mean score for the in-person information session met the noninferiority criterion for this investigation (Delta = 0.68; 95% CI = 0.18 to 1.26). In a multivariable linear regression model, Blacks/African Americans, Hispanics, and those with Medicare and Medicaid insurance exhibited slightly lower mean scores, regardless of the pretest information delivery format. There was a strong relationship between fewer years of formal education and lower mean scores on the questionnaire. Age, gender, type of insurance, partner/marital status, and history of prior HIV testing were not predictive of scores on the questionnaire.

CONCLUSIONS

In terms of patient comprehension of rapid HIV pretest information fundamentals, the video was an acceptable substitute to pretest information delivered by an HIV test counselor. Both the video and the in-person information session were less effective in providing pretest information for patients with fewer years of formal education.

Nomenclature and definitions for emergency department human immunodeficiency virus (HIV) testing: report from the 2007 conference of the National Emergency Department HIV Testing Consortium

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.

Bloodborne viral hepatitis infections among drug users: the role of vaccination

Drug use is a prevalent world-wide phenomenon and hepatitis virus infections are traditionally a major health problem among drug users (DUs). HBV and HCV, and to a lesser extent HAV, are easily transmitted through exposure to infected blood and body fluids. Viral hepatitis is not inevitable for DUs. Licensed vaccines are available for hepatitis A and hepatitis B. The purpose of this overview is to show some epidemiological data about HBV and the other blood-borne viral hepatitis among DUs and to summarize and discuss use of hepatitis vaccinations in this population. Successful vaccination campaigns among DUs are feasible and well described. We try to focus on the most significant results achieved in successful vaccination programs as reported in scientific literature. Vaccination campaigns among DUs represent a highly effective form of health education and they are cost-saving.

Scope of rapid HIV testing in urban U.S. hospitals

OBJECTIVE

The present study examined the scope of rapid human immunodeficiency virus (HIV) testing in urban U.S. hospitals.

METHODS

In a multistage national probability sample, 12 primary metropolitan statistical areas (three per region) were sampled randomly, with weights proportionate to acquired immunodeficiency syndrome (AIDS) populations. All 671 eligible hospitals within areas were selected. Laboratory staff from 584 hospitals (87%) were interviewed by telephone in 2005.

RESULTS

About 52% reported rapid HIV test availability (50% in occupational health, 29% in labor and delivery, and 13% in emergency department/urgent care), and 86% of hospitals offering rapid tests processed them in the laboratory. In multivariate models, rapid test availability was more likely in hospitals serving more patients, and located in high-poverty, high-AIDS prevalence areas, and in the South or Midwest vs. West. It was less likely in hospitals serving areas with large percentages of people who were black/African American or Hispanic/Latino (p<0.05).

CONCLUSIONS

Rapid HIV testing is increasing across urban U.S. hospitals, primarily for occupational exposure and in hospitals with greater resources and need. To achieve routine HIV screening, policies should encourage greater breadth of diffusion of rapid testing at the point of care, especially in smaller facilities, the West, and communities with racial/ethnic diversity.

Contributions to early HIV diagnosis among patients linked to care vary by testing venue

OBJECTIVE

Early HIV diagnosis reduces transmission and improves health outcomes; screening in non-traditional settings is increasingly advocated. We compared test venues by the number of new diagnoses successfully linked to the regional HIV treatment center and disease stage at diagnosis.

METHODS

We conducted a retrospective cohort study using structured chart review of newly diagnosed HIV patients successfully referred to the region's only HIV treatment center from 1998 to 2003. Demographics, testing indication, risk profile, and initial CD4 count were recorded.

RESULTS

There were 277 newly diagnosed patients meeting study criteria. Mean age was 33 years, 77% were male, and 46% were African-American. Median CD4 at diagnosis was 324. Diagnoses were earlier via partner testing at the HIV treatment center (N = 8, median CD4 648, p = 0.008) and with universal screening by the blood bank, military, and insurance companies (N = 13, median CD4 483, p = 0.05) than at other venues. Targeted testing by health care and public health entities based on patient request, risk profile, or patient condition lead to later diagnosis.

CONCLUSION

Test venues varied by the number of new diagnoses made and the stage of illness at diagnosis. To improve the rate of early diagnosis, scarce resources should be allocated to maximize the number of new diagnoses at screening venues where diagnoses are more likely to be early or alter testing strategies at test venues where diagnoses are traditionally made late. Efforts to improve early diagnosis should be coordinated longitudinally on a regional basis according to this conceptual paradigm.

Improving HIV screening and receipt of results by nurse-initiated streamlined counseling and rapid testing

BACKGROUND

HIV testing is cost-effective in unselected general medical populations, yet testing rates among those at risk remain low, even among those with regular primary care. HIV rapid testing is effective in many healthcare settings, but scant research has been done within primary care settings or within the US Department of Veteran's Affairs Healthcare System.

OBJECTIVES

We evaluated three methods proven effective in other diseases/settings: nurse standing orders for testing, streamlined counseling, and HIV rapid testing.

DESIGN

Randomized, controlled trial with three intervention models: model A (traditional counseling/testing); model B (nurse-initiated screening, traditional counseling/testing); model C (nurse-initiated screening, streamlined counseling/rapid testing).

PARTICIPANTS

Two hundred fifty-one patients with primary/urgent care appointments in two VA clinics in the same city (one large urban hospital, one freestanding outpatient clinic in a high HIV prevalence area).

MEASUREMENTS

Rates of HIV testing and receipt of results; sexual risk reduction; HIV knowledge improvement.

RESULTS

Testing rates were 40.2% (model A), 84.5% (model B), and 89.3% (model C; p = <.01). Test result receipt rates were 14.6% (model A), 31.0% (model B), 79.8% (model C; all p = <.01). Sexual risk reduction and knowledge improvement did not differ significantly between counseling methods.

CONCLUSIONS

Streamlined counseling with rapid testing significantly increased testing and receipt rates over current practice without changes in risk behavior or posttest knowledge. Increased testing and receipt of results could lead to earlier disease identification, increased treatment, and reduced morbidity/mortality. Policymakers should consider streamlined counseling/rapid testing when implementing routine HIV testing into primary/urgent care.

Interpreting and implementing the 2006 CDC recommendations for HIV testing in health-care settings

On September 22, 2006, the Centers for Disease Control and Prevention (CDC) announced recommendations to expand the role of health-care providers in human immunodeficiency virus (HIV) testing. These clearlyjustified guidelines aim to remove traditional testing barriers, and thereby increase the rate of earlier diagnosis. This overarching strategy to increase testing in all health-care settings also includes less traditional sites such as emergency departments and correctional health-care facilities. The motivation for the guidelines is intuitive, as the need for augmented testing is well supported. Of those infected with HIV in the U.S., approximately one-quarter are unaware of their disease status. People who are unaware of their infection disproportionately account for new transmissions and are unable to benefit from treatment. The HIV incidence has not fallen below approximately 40,000 new diagnoses per year, of which approximately 40% are diagnosed late in the course of infection. Universal screening, even in populations with a disease prevalence of 0.1%, has been shown to be cost-effective. While the guidelines have been reviewed in depth, current interpretations do not adequately outline a structure for further debate or facilitate incremental or partial implementation of the recommendations. This must be remedied, as comprehensive implementation of the guidelines will be controversial or logistically impossible in many settings for the foreseeable future. Herein, we provide a clarified interpretation by outlining the core guideline elements individually and within the context of current barriers to implementation. We then discuss potential combinations of the core elements that would enable increased testing in settings where comprehensive guideline implementation is not possible.

Intimate partner violence prevalence and HIV risks among women receiving care in emergency departments: implications for IPV and HIV screening

OBJECTIVE

To examine (1) the prevalence of experiencing physical, injurious and sexual intimate partner violence (IPV) and (2) the associations between HIV risks and different types of IPV among women receiving care in an inner city emergency department (ED).

METHODS

A cross-sectional survey that elicited self-reported HIV risks and IPV among a random sample of 799 women receiving ED care. Multiple logistic regression was used to examine the associations between HIV risk and IPV, with covariance adjustment for potentially confounding sociodemographics.

RESULTS

49.6% of the women reported a history of any form (ie, minor and severe type) of physical, injurious and/or sexual IPV, 15% severe sexual coercion (rape) over life time and 11.8% IPV in the past 6 months. Women who reported engaging in sex with a HIV-infected partner or an injecting drug user (IDU), having multiple partners in the past 12 months and injecting drugs were significantly more likely to have experienced any form of physical/injurious IPV, severe physical/injurious IPV and any form of sexual IPV in the past 6 months. In addition, women with multiple partners in the past 12 months and women who reported injecting drugs were significantly more likely to indicate having experienced a severe form of sexual IPV in the past 6 months.

CONCLUSION

For many women receiving care in EDs, IPV and several HIV risk behaviours are frequent, co-occurring health problems. HIV testing and routine IPV inquiry in ED settings offer an important opportunity to identify women who are affected by these overlapping epidemics and refer them to appropriate treatment services.

The role of the emergency department in the care of homeless and disadvantaged populations

This article provides an overview of the role of the emergency department (ED) in the care of homeless and disadvantaged populations. It suggests that organized emergency medicine can have a significant impact on total community health by maintaining a universal "safety net" for the delivery of integrated health and human services. The epidemiology of social deprivation among ED patients is examined, with a particular focus on homelessness. Current research on the value of socio-medical integration in the ED setting is discussed, with emphasis on selected initiatives that have demonstrated feasibility, cost-effectiveness, and impact.

An educational HIV pretest counseling video program for off-hours testing in the emergency department

STUDY OBJECTIVE

Multiple barriers to traditional pretest HIV counseling make HIV testing difficult to accomplish in the emergency department setting in off hours. This study compares the educational effectiveness of a 10-minute pretest counseling video with the usual practice of a session with an HIV counselor.

METHODS

This was a prospective randomized controlled trial of adult patients presenting to the urgent care area of a busy inner-city hospital. Patients either viewed an HIV educational video or spoke with an HIV counselor for pretest counseling. The video was developed by 2 of the investigators (YC, MH) and covered essential educational elements for HIV testing, as required by the New York State Department of Health. All participants completed a measure of HIV knowledge after their intervention. An equivalence analysis was performed to assess whether the video was at least as good as counseling in terms of overall mean knowledge score.

RESULTS

Of 129 patients recruited for the study, 65 patients were randomized to the intervention and 64 patients to the control group. Five patients were unable to complete the study. The final analysis was based on 124 patients. Mean knowledge scores were higher in the intervention (85.3% versus 79.7%; 90% confidence interval for the difference 2.6% to 8.7%).

CONCLUSION

We conclude that the use of an educational video with an inner-city adult population was at least as effective as in-person pretest counseling in conveying information related to HIV testing.

Health department collaboration with emergency departments as a model for public health programs among at-risk populations

OBJECTIVES

Accessing at-risk and underserved populations for intervention remains a major obstacle for public health programs. Emergency departments (EDs) care for patients not otherwise interacting with the health care system, and represent a venue for such programs. A variety of perceived and actual barriers inhibit widespread implementation of ED-based public health programs. Collaboration between local health departments and EDs may overcome such barriers. The goal of this study was to assess the effectiveness of a health department-funded, ED-based public health program in comparison with other similar community-based programs through analysis of data reported by health department-funded HIV counseling and testing centers in one Ohio county.

METHOD

Data for HIV counseling and testing at publicly funded sites in southwestern Ohio from January 1999 through December 2002 were obtained from the Ohio Department of Health. Demographic and risk-factor profiles were compared between the counseling and testing program located in the ED of a large, urban teaching hospital and the other publicly funded centers in the same county.

RESULTS

A total of 26,382 patients were counseled and tested; 5,232 were ED patients, and 21,150 were from community sites. HIV positivity was 0.86% (95% confidence interval [CI] 0.64%, 1.15%) in the ED and 0.65% (95% CI 0.55%, 0.77%) elsewhere. The ED program accounted for 19.8% of all tests and 24.7% of all positive results. The ED notified 77.3% of individuals testing positive and 84.4% of individuals testing negative. At community program centers, 88.3% of patients testing positive and 63.8% of patients testing negative were notified of results. All ED patients notified of positive status were successfully referred to infectious disease specialists.

CONCLUSIONS

Public health programs can operate effectively in the ED. EDs should have a rapidly expanding role in the national public health system.

Emergency Department HIV Testing and Counseling: An Ongoing Experience in a Low-Prevalence Area

STUDY OBJECTIVE

Despite recommendations, emergency department (ED)-based HIV screening is not widespread, and feasibility studies are generally limited to settings with high HIV prevalence (>1%). This investigation was to evaluate an ongoing, publicly funded, ED-based HIV counseling and testing program in a low-prevalence area.

METHODS

We reviewed a database of patients treated by an ED-based HIV counseling and testing program at a large, urban, teaching hospital for 1998 to 2002. ED patients at risk for HIV were targeted for standard serologic testing and counseling. Data were collected prospectively using standardized forms as part of clinical operations rather than in the context of rigorous research methodology; patient-oriented outcomes were not assessed. Counselors were trained according to Centers for Disease Control and Prevention guidelines, and health department guidelines for counseling and testing centers were followed. The main outcome measure was the number and proportion of patients newly diagnosed with HIV.

RESULTS

Eight thousand five hundred seventy-four patients were approached; 5,504 consented to HIV testing. Mean age was 29 years (SD 9.4 years), 76% were black, and 50% were men. Five thousand three hundred seventy-four (97.6%) patients tested negative and 39 (0.7%) patients tested positive. Seventy-five percent of negative-test patients and 79% of positive-test patients were notified of test results. Information for seropositive patients not notified of results was forwarded to the health department. All notified HIV-positive patients entered treatment. Risk factors included sexually transmitted disease (47%), multiple sexual partners (40%), unprotected sex while using drugs or alcohol (30%), men having sex with men (5%), and intravenous drug use (4%).

CONCLUSION

Identification of HIV-positive patients is possible in low-prevalence ED settings. In this instance, it was possible to perpetuate an ED-based HIV intervention program during an extended time. Although our work expands the profile of ED-based HIV counseling and testing beyond previous reports, the results should not be overgeneralized.

Seasonal variation in undiagnosed HIV infection on the general medicine and trauma services of two urban hospitals

OBJECTIVE

To examine the seroprevalence of undiagnosed HIV and variation by season among patients admitted to the general internal medicine (GIM) and trauma services of two urban hospitals.

DESIGN

A cross-sectional blinded HIV-1 seroprevalence survey.

SETTING

A 725-bed academic medical center's hospital and an affiliated 324-bed tertiary care hospital.

PARTICIPANTS

Residual serological specimens were obtained for unique patients aged 17 to 65 to study services in summer (June 16 to September 4, 2001) and fall to winter (November 1, 2001 to January 8, 2002).

METHODS

Hospital files provided data on demographics, service type, and discharge clinical categories (fall-winter group only). HIV ELISA (enzyme-linked immunosorbent assay) tests with confirmatory Western blot were linked to subjects' de-identified files. We excluded 34 subjects with known HIV. Of the remaining unique admissions in summer (n=604) and fall-winter (n=978), 60% and 55% were tested, respectively. Predictors of undiagnosed HIV infection were examined using multivariate analysis.

RESULTS

The summer cohort (n=362) had significantly lower unadjusted seroprevalence of undiagnosed HIV infection (1.4%; 95% confidence interval [CI], 0.4% to 3.2%) than the fall-winter cohort (n=539; 3.7%; 95% CI, 2.3% to 5.7%; P=.04). Overall, undiagnosed HIV was somewhat less likely in women (adjusted odds ratio [AOR], 0.45; 95% CI, 0.19 to 1.07) but more likely in black patients (AOR, 3.46; 95% CI, 0.70 to 17.06). In the fall-winter cohort, undiagnosed HIV was more likely for discharges with the following clinical categories versus those with a cardiac condition: dermatologic/breast (AOR, 14.90; 95% CI, 1.20 to 184.77), renal/urological (AOR, 22.43; 95% CI, 2.12 to 236.75), or infectious (AOR, 31.08; 95% CI, 2.40 to 402.98).

CONCLUSIONS

The higher seroprevalence of undiagnosed HIV in the fall-winter admissions to GIM and trauma services supports especially targeting HIV testing in these months.

Current Centers for Disease Control and Prevention guidelines for HIV counseling, testing, and referral: critical role of and a call to action for emergency physicians

Although the rate of new cases of HIV infection has been relatively stable during the past decade, it remains unacceptably high, with 40,000 individuals newly infected each year. In 2001, the Centers for Disease Control and Prevention (CDC) issued revised guidelines for HIV counseling, testing, and referral directed toward promoting further reduction of HIV acquisition and transmission. The guidelines give explicit emphasis to the role of emergency physicians, according to recognition that the emergency department (ED) represents the only source of medical care for many patients and often serves as the primary site for routine health care to communities at risk for HIV. Despite the time and practical limitations inherent in ED practice, many studies suggest that routine HIV counseling, testing, and referral in the ED may be feasible and effective. This article reviews those studies in the context of the most up-to-date CDC HIV counseling, testing, and referral guidelines.
