Characteristics of U.S. emergency departments that offer routine human immunodeficiency virus screening

Innovation and implementation determinants of HIV testing and linkage-to-care in the U.S.: a systematic review

OBJECTIVE

To identify innovation and implementation determinants of HIV testing, diagnosis, and linkage-to-care in the U.S.

DATA SOURCES AND STUDY SETTING

Between November 2020 and January 2022, a broad search strategy was employed in three literature databases: Ovid MEDLINE, PsycINFO, and Web of Science.

STUDY DESIGN

A systematic review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement.

DATA COLLECTION/EXTRACTION METHODS

A team of master's and Ph.D.-level researchers screened eligible studies against the inclusion criteria and extracted the data using COVIDENCE software in pairs with consensus performed by a senior member of the team. Barriers and facilitators were extracted and analyzed according to the Consolidated Framework for Implementation Research (CFIR). Frequency of determinants across studies was mapped according to CFIR, valence, study design, delivery setting, unit of analysis, population of interest, region of the U.S., and year.

RESULTS

We identified 1,739 implementation and innovation determinants from 186 articles. Most determinants were for HIV testing rather than linkage-to-care. Most determinants were identified in the inner setting and individuals domains of CFIR, with the fewest identified in the process and innovations domains. Determinants of providers were only slightly more frequently identified than determinants of recipients. However, determinants of organizations and systems were rarely identified.

CONCLUSION

This review provides a synthesis of innovation and implementation determinants of HIV testing and linkage-to-care using the most-cited implementation science (IS) framework, CFIR. This synthesis enables the larger field of HIV science to utilize IS in efforts to end the HIV epidemic and positions IS to consider the application of IS frameworks to fields like HIV.

Estimates of HIV testing at visits to United States emergency departments

OBJECTIVES

Emergency department-based HIV testing rates are historically low, but recent testing trends surrounding the COVID-19 pandemic and launch of the Ending the HIV Epidemic (EHE) initiative are unknown. The objective of the study is to estimate recent trends in the proportion of emergency department visits that included HIV testing.

METHODS

We performed a cross-sectional analysis of the National Hospital Ambulatory Medical Care Survey (NHAMCS), a weighted nationally representative survey of US emergency departments, from 2014 to 2020. Given EHE's focus on several rural Southern jurisdictions as well as populations disproportionately affected by HIV, we stratified by characteristics including US region and visit-listed race and ethnicity.

RESULTS

The proportion of emergency department visits that included HIV testing increased from 2014 (0.6%) to 2018 (1.1%) but was lower in 2019 and 2020 (0.8%). Compared with other regions, the South had the lowest rates of testing in both 2019 (0.6%) and 2020 (0.5%); testing rates in the nonmetropolitan South remained 0.1% or less across all years. Testing rates for emergency department visits by persons who identified as Hispanic/Latino were highest in 2018 (2.2%) but were sharply lower in 2019 and 2020 (0.8%).

CONCLUSION

After a small but insufficient increase in emergency department-based HIV testing since 2014, rates decreased between 2018 and 2019 and were stable between 2019 and 2020. Overall, very few emergency department visits during our entire study period included an HIV test, and there were persistently low rates of HIV testing for populations prioritized in national efforts and during visits in rural jurisdictions in the South.

High Rate of HIV Among Trauma Patients Participating in Routine Emergency Department Screening

Limited published data suggest rates of HIV may be high among trauma patients. This study compares rates of HIV screening and diagnosis among trauma and medical patients at a Level 1 trauma center emergency department (ED) with a universal HIV screening program. This is a retrospective cross-sectional study of all ED encounters from May 1, 2018, through May 1, 2021. Duplicate encounters, encounters with repeat testing within one year, and patients younger than 18 or older than 65 were excluded. Chi-squared analysis was used to compare demographics, rates of HIV testing, new and known HIV infections, and linkage to care between trauma and medical patients. After exclusion criteria were applied, 147,430 encounters from 91,468 unique patients were analyzed. Trauma comprised 7,497 (5.4%) encounters. Trauma patients were less likely to be screened for HIV than medical patients (18.1% vs 25.6%; OR 0.64; 95%CI, 0.61-0.68, p < .01). Trauma patients had higher rates of HIV (2.2% vs 1.3%; OR 1.78; 95% CI, 1.22-2.58, p < .01). Both trauma and medical patients would benefit from strategies to increase screening. Including trauma patients in routine ED HIV screening should be a priority to increase diagnosis rate and linkage to care in key populations.

Comparison of US emergency departments by HIV priority jurisdiction designation: A case for geographically targeted screening in teaching hospitals

The Ending the HIV Epidemic (EHE) Initiative targets a subset of United States (US) priority jurisdictions hardest hit by HIV. It remains unclear which emergency departments (EDs) are the most appropriate targets for EHE-related efforts. To explore this, we used the 2001-2019 National Emergency Department Inventories (NEDI)-USA as a framework to characterize all US EDs, focusing on those in priority jurisdictions and those affiliated with a teaching hospital. We then incorporate multivariable regression to explore the association between ED characteristics and location in an HIV priority jurisdiction. Further, to provide context on the communities these EDs serve, demographic and socioeconomic information and sexually transmitted infection case rate data were included. This reflected 2019 US Census Bureau data on age, race, ethnicity, and proportion uninsured and living in poverty along with 2001-2019 Centers for Disease Control and Prevention case rate data on chlamydia, gonorrhea, and syphilis. We found that EDs in priority jurisdictions (compared to EDs not in priority jurisdictions) more often served populations emphasized in HIV-related efforts (i.e., Black or African American or Hispanic or Latino populations), communities with higher proportions uninsured and living in poverty, and counties with higher rates of chlamydia, gonorrhea, and syphilis. Further, of the groups studied, EDs with teaching hospital affiliations had the highest visit volumes and had steady visit volume growth. In regression, ED annual visit volume was associated with an increased odds of an ED being located in a priority jurisdiction. Our results suggest that geographically targeted screening for HIV in a subset of US priority jurisdiction EDs with a teaching hospital affiliation could be an efficient means to reach vulnerable populations and reduce the burden of undiagnosed HIV in the US.

Characteristics of California Emergency Departments in Centers for Disease Control and Prevention-Designated HIV Priority Counties

BACKGROUND

Refocused national HIV testing initiatives include a geographic focus.

OBJECTIVE

Using a geographic focus, we sought to identify which emergency departments (EDs) might be the most efficient targets for future HIV testing efforts, using California as an example.

METHODS

Retrospective analysis of California EDs, emergency physicians, and patients served, along with county-level estimates of HIV prevalence and proportion of the population living in poverty. Emphasis was placed on characterizing EDs affiliated with teaching hospitals and those located in Centers for Disease Control (CDC) and Prevention HIV priority counties.

RESULTS

Of the 320 EDs studied, 178 were in priority counties, 29 were affiliated with teaching hospitals, and 24 had both characteristics. Of the 12,869,889 ED visits included, 61.8% occurred in priority counties, 14.7% in EDs affiliated with teaching hospitals, and 12.0% in EDs with both characteristics. The subset of EDs in priority counties with teaching hospital affiliations (compared with priority and nonpriority county ED groups without a teaching hospital affiliation) had higher overall median visit volumes and higher proportions of visits by at-risk and CDC-targeted populations (e.g., individuals who were homeless, those who identified as Black or African American race, and those who identified as Hispanic or Latino ethnicity, all p < 0.01).

CONCLUSIONS

EDs in priority counties affiliated with teaching hospitals are major sources of health care in California. These EDs more often serve populations disproportionately impacted by HIV. These departments are efficient targets to direct testing efforts. Increasing testing in these EDs could reduce the burden of undiagnosed HIV in California.

HIV Testing at Visits to US Emergency Departments, 2018

BACKGROUND

An early HIV diagnosis improves patient outcomes, reduces the burden of undiagnosed HIV, and limits transmission. There is a need for an updated assessment of HIV testing rates in the emergency department (ED).

SETTING

The National Hospital Ambulatory Medical Care Survey sampling ED visits were weighted to give an estimate of ED visits across all US states in 2018.

METHODS

We analyzed patients aged 13-64 years without known HIV and estimated ED visits with HIV testing and then stratified by race, ethnicity, and region. Descriptive statistics and mapping were used to illustrate and compare patient, visit, and hospital characteristics for visits with HIV testing.

RESULTS

Of 83.0 million weighted visits to EDs in 2018 by patients aged 13-64 years without a known HIV infection (based on 13,237 National Hospital Ambulatory Medical Care Survey sample visits), HIV testing was performed in 1.05% of visits. HIV testing was more frequent for patients aged 13-34 years compared with that for patients aged 35-64 years (1.32% vs. 0.82%, P = 0.056), Black patients compared with that for White and other patients (1.73% vs. 0.79% and 0.41%, P = 0.002), Hispanic or Latino patients compared with that for non-Hispanic or Latino patients (2.18% vs. 0.84%, P = 0.001), and patients insured by Medicaid compared with that for patients insured by private or other insurance (1.71% vs. 0.64% and 0.96%, P = 0.003). HIV testing rates were the highest in the Northeast (1.72%), followed by the South (1.05%).

CONCLUSIONS

HIV testing occurred in a minority of ED visits. There are differences in rates of HIV testing by race, ethnicity, and location. Although rates of testing have increased, rates of ED-based HIV testing remain low.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Asymptomatic Adolescent HIV: Identifying a Role for Universal HIV Screening in the Pediatric Emergency Department

Adolescents account for most undiagnosed HIV infections in the United States. Although the Centers for Disease Control and Prevention (CDC) recommends universal HIV screening for all patients ≥13 years, <10% of adolescents have been tested for HIV. To identify earlier opportunities for adolescent HIV prevention and diagnosis in a region of high HIV prevalence, we sought to describe pediatric emergency department (PED) visits made by a retrospective cohort of adolescents who were later diagnosed with HIV as young adults (<25 years) through an adult emergency department (ED) universal HIV screening program. CD4+ count was used to estimate the time of HIV infection before diagnosis and all PED visits in the 10 years before diagnosis were analyzed. Universal HIV screening in the adult ED diagnosed 193 young adults (median 22 years; 90% men; 29% stage 3); 70% had CD4+ at diagnosis that was used to estimate time of infection (mean 3.8 years). Thirty-eight HIV-infected young adults had a total of 109 PED visits in the 10 years before HIV diagnosis. Sexual history was documented in 12% of PED visits and a sexually transmitted infection test was sent in 6%. Ten HIV-infected young adults had 26 PED visits during the time in which they were likely already infected with HIV, each a potential missed opportunity for earlier diagnosis. HIV-infected and at-risk adolescents are underrecognized in PED visits. Implementation of CDC-recommended universal screening may lead to earlier diagnoses and improve outcomes; the PED may also be critical in identifying adolescents eligible for preexposure prophylaxis.

Cash incentives versus defaults for HIV testing: A randomized clinical trial

BACKGROUND

Tools from behavioral economics have been shown to improve health-related behaviors, but the relative efficacy and additive effects of different types of interventions are not well established. We tested the influence of small cash incentives, defaults, and both in combination on increasing patient HIV test acceptance.

METHODS AND FINDINGS

We conducted a randomized clinical trial among patients aged 13-64 receiving care in an urban emergency department. Patients were cross-randomized to $0, $1, $5, and $10 incentives, and to opt-in, active-choice, and opt-out test defaults. The primary outcome was the proportion of patients who accepted an HIV test. 4,831 of 8,715 patients accepted an HIV test (55.4%). Those offered no monetary incentive accepted 51.6% of test offers. The $1 treatment did not increase test acceptance (increase 1%; 95% confidence interval [CI] -2.0 to 3.9); the $5 and $10 treatments increased test acceptance rates by 10.5 and 15 percentage points, respectively (95% CI 7.5 to 13.4 and 11.8 to 18.1). Compared to opt-in testing, active-choice testing increased test acceptance by 11.5% (95% CI 9.0 to 14.0), and opt-out testing increased acceptance by 23.9 percentage points (95% CI 21.4 to 26.4).

CONCLUSIONS

Small incentives and defaults can both increase patient HIV test acceptance, though when used in combination their effects were less than additive. These tools from behavioral economics should be considered by clinicians and policymakers. How patient groups respond to monetary incentives and/or defaults deserves further investigation for this and other health behaviors.

Undiagnosed HIV and HCV Infection in a New York City Emergency Department, 2015

OBJECTIVES

To measure undiagnosed HIV and HCV in a New York City emergency department (ED).

METHODS

We conducted a blinded cross-sectional serosurvey with remnant serum from specimens originally drawn for clinical indications in the ED. Serum was deduplicated and matched to (1) the hospital's electronic medical record and (2) the New York City HIV and HCV surveillance registries for evidence of previous diagnosis before being deidentified and tested for HIV and HCV.

RESULTS

The overall prevalence of HIV was 5.0% (250/4990; 95% confidence interval [CI] = 4.4%, 5.7%); the prevalence of undiagnosed HIV was 0.2% (12/4990; 95% CI = 0.1%, 0.4%); and the proportion of undiagnosed HIV was 4.8% (12/250; 95% CI = 2.5%, 8.2%). The overall prevalence of HCV (HCV RNA ≥ 15 international units per milliliter) was 3.9% (196/4989; 95% CI = 2.8%, 5.1%); the prevalence of undiagnosed HCV was 0.8% (38/4989; 95% CI = 0.3%, 1.3%); and the proportion of undiagnosed HCV was 19.2% (38/196; 95% CI = 11.4%, 27.0%).

CONCLUSIONS

Undiagnosed HCV was more prevalent than undiagnosed HIV in this population, suggesting that aggressive testing initiatives similar to those directed toward HIV should be mounted to improve HCV diagnosis.

HIV Testing Among Men at Risk for Acquiring HIV Infection Before and After the 2006 CDC Recommendations

OBJECTIVES

Testing for human immunodeficiency virus (HIV) is the key first step in HIV treatment and prevention. In 2006, the Centers for Disease Control and Prevention (CDC) recommended annual HIV testing for people at high risk for HIV infection. We evaluated HIV testing among men with high-risk heterosexual (HRH) contact and sexually active men who have sex with men (MSM) before and after the CDC recommendations.

METHODS

We used data from the National Survey of Family Growth, 2002 and 2006-2010, to assess proportions of HRH respondents and MSM reporting HIV testing in the prior 12 months, compare rates of testing before and after release of the 2006 CDC HIV testing guidelines, and examine demographic variables and receipt of health-care services as correlates of HIV testing.

RESULTS

Among MSM, the proportion tested was 37.2% (95% confidence interval [CI] 28.2, 47.2) in 2002, 38.2% (95% CI 25.9, 52.2) in 2006-2008, and 41.7% (95% CI 29.2, 55.3) in 2008-2010; among HRH respondents, the proportion was 23.7% (95% CI 20.5, 27.3) in 2002, 24.5% (95% CI 20.9, 28.7) in 2006-2008, and 23.9% (95% CI 20.2, 28.1) in 2008-2010. HIV testing was more likely among MSM and HRH respondents who received testing or treatment for sexually transmitted disease in the prior 12 months, received a physical examination in the prior 12 months (MSM only), or were incarcerated in the prior 12 months.

CONCLUSIONS

The rate of annual HIV testing was low for men with sexual risk for HIV infection, and little improvement took place from 2002 to 2006-2010. Interventions aimed at men at risk, especially MSM, in both nonmedical and health-care settings, likely could increase HIV testing.

Comparison of HIV Testing Uptake in an Urban Academic Emergency Department Using Different Testing Assays and Support Systems

Despite 2006 recommendations by the Centers for Disease Control and Prevention for opt-out HIV testing in all healthcare settings, Emergency Department (ED) testing has been limited. We conducted an observational cohort study to assess the impact of two workflow interventions on the proportion of HIV tests ordered in an urban academic ED. First, a 4(th)-generation HIV antigen/antibody combination test replaced the existing assay, and ED staff continued to notify patients of their reactive tests. Six months later, the HIV Rapid Diagnosis Team, composed of an Infectious Diseases (ID) physician and the HIV Advanced Practice Nurse, immediately assisted with disclosure of positive results to the patients and facilitated linkage to outpatient care. The new assay did not change the proportion of HIV tests ordered (0.14-0.11%, χ2, p = 0.2). However, ID support was associated with a statistically significant increase in the proportion of HIV tests ordered (0.14-0.43%, χ2, p < 0.00010) and a nonstatistically significant increase in the proportion of new HIV diagnoses (1.6-6.8%, Fisher exact test = 0.113). Male gender and lack of insurance were associated with a reactive HIV test. Reduction of barriers to linkage to outpatient HIV care through a collaborative relationship between the ED and ID team increased HIV testing and diagnosis. The role of this model as a component of a universal HIV screening program will need to be further assessed.

Prevalence of Diagnosed and Undiagnosed Hepatitis C in a Midwestern Urban Emergency Department

BACKGROUND

Targeted hepatitis C virus (HCV) screening is recommended. Implementation of screening in emergency department (ED) settings is challenging and controversial. Understanding HCV epidemiology in EDs could motivate and guide screening efforts. We characterized the prevalence of diagnosed and undiagnosed HCV in a Midwestern, urban ED.

METHODS

This was a cross-sectional seroprevalence study using de-identified blood samples and self-reported health information obtained from consecutively approached ED patients aged 18-64 years. Subjects consented to a "study of diseases of public health importance" and were compensated for participation. The Biochain ELISA kit for Human Hepatitis C Virus was used for antibody assay. Viral RNA was isolated using the Qiagen QIAamp UltraSens Virus kit, followed by real-time reverse transcription polymerase chain reaction using a Bio-Rad CFX96 SYBR Green UltraFast program with melt-curve analysis.

RESULTS

HCV antibody was detected in 128 of 924 (14%; 95% confidence interval [CI], 12%-16%) samples. Of these, 44 (34%) self-reported a history of HCV or hepatitis of unknown type and 103 (81%; 95% CI, 73%-87%) were RNA positive. Two additional patients were antibody negative but RNA positive. Fully implemented birth cohort screening for HCV antibody would have missed 36 of 128 (28%) of cases with detectable antibody and 26 of 105 (25%) of those with replicative HCV infection.

CONCLUSIONS

HCV infection is highly prevalent in EDs. Emergency departments are likely to be uniquely important for HCV screening, and logistical challenges to ED screening should be overcome. Birth cohort screening would have missed many patients, suggesting the need for complementary screening strategies applied to an expanded age range.

Patient choice in opt-in, active choice, and opt-out HIV screening: randomized clinical trial

STUDY QUESTION

What is the effect of default test offers--opt-in, opt-out, and active choice--on the likelihood of acceptance of an HIV test among patients receiving care in an emergency department?

METHODS

This was a randomized clinical trial conducted in the emergency department of an urban teaching hospital and regional trauma center. Patients aged 13-64 years were randomized to opt-in, opt-out, and active choice HIV test offers. The primary outcome was HIV test acceptance percentage. The Denver Risk Score was used to categorize patients as being at low, intermediate, or high risk of HIV infection.

STUDY ANSWER AND LIMITATIONS

38.0% (611/1607) of patients in the opt-in testing group accepted an HIV test, compared with 51.3% (815/1628) in the active choice arm (difference 13.3%, 95% confidence interval 9.8% to 16.7%) and 65.9% (1031/1565) in the opt-out arm (difference 27.9%, 24.4% to 31.3%). Compared with active choice testing, opt-out testing led to a 14.6 (11.1 to 18.1) percentage point increase in test acceptance. Patients identified as being at intermediate and high risk were more likely to accept testing than were those at low risk in all arms (difference 6.4% (3.4% to 9.3%) for intermediate and 8.3% (3.3% to 13.4%) for high risk). The opt-out effect was significantly smaller among those reporting high risk behaviors, but the active choice effect did not significantly vary by level of reported risk behavior. Patients consented to inclusion in the study after being offered an HIV test, and inclusion varied slightly by treatment assignment. The study took place at a single county hospital in a city that is somewhat unique with respect to HIV testing; although the test acceptance percentages themselves might vary, a different pattern for opt-in versus active choice versus opt-out test schemes would not be expected.

WHAT THIS PAPER ADDS

Active choice is a distinct test regimen, with test acceptance patterns that may best approximate patients' true preferences. Opt-out regimens can substantially increase HIV testing, and opt-in schemes may reduce testing, compared with active choice testing.

Benefits of a routine opt-out HIV testing and linkage to care program for previously diagnosed patients in publicly funded emergency departments in Houston, TX

BACKGROUND

The Routine Universal Screening for HIV program provides opt-out HIV testing and linkage to care for emergency department (ED) patients in Harris Health System, Houston, TX. Seventy-five percent of patients testing positive in this program have been previously diagnosed. Whether linkage to care is increased among these patients is unknown.

METHODS

We conducted a retrospective cohort study of persons tested for HIV in the ED between 2008 and 2012 but had a previously documented positive HIV test ≥1 year prior. Outcomes were engagement in care (≥1 HIV outpatient visits in 6 months), retention in care (≥2 HIV outpatient visits in 12 months, at least 3 months apart), and virologic suppression (<200 copies/mL in 12 months) compared before and after the ED visit. Analysis was conducted using McNemar test and multivariate conditional logistic regression.

RESULTS

A total of 202,767 HIV tests identified 2068 previously diagnosed patients. The mean age was 43 years with 65% male and 87% racial and ethnic minorities. Engagement in care increased from 41.3% previsit to 58.8% postvisit (P < 0.001). Retention in care increased from 32.6% previsit to 47.1% postvisit (P < 0.001). Virologic suppression increased from 22.8% previsit to 34.0% postvisit (P < 0.001). Analyses revealed that engagement in care after visit improved most among younger participants (ages 16-24 years), retention improved across all groups, and virologic suppression improved most among participants aged 25-34 years.

CONCLUSIONS

Routine opt-out HIV testing in an ED paired with standardized service linkage improves engagement, retention, and virologic suppression in previously diagnosed patients.

A Novel Approach to Realizing Routine HIV Screening and Enhancing Linkage to Care in the United States: Protocol of the FOCUS Program and Early Results

BACKGROUND

The United States health care system remains far from implementing the Centers for Disease Control and Prevention's recommendation of routine human immunodeficiency virus (HIV) screening as part of health care for adults. Although consensus for the importance of screening has grown, innovations in implementing routine screening are still lacking. HIV on the Frontlines of Communities in the United States (FOCUS) was launched in 2010 to provide an environment for testing innovative approaches to routine HIV screening and linkage to care.

OBJECTIVE

The strategy of the FOCUS program was to develop models that maximize the use of information systems, fully integrate HIV screening into clinical practice, transform basic perceptions about routine HIV screening, and capitalize on emerging technologies in health care settings and laboratories.

METHODS

In 10 of the most highly impacted cities, the FOCUS program supports 153 partnerships to increase routine HIV screening in clinical and community settings.

RESULTS

From program launch in 2010 through October 2013, the partnerships have resulted in a total of 799,573 HIV tests and 0.68% (5425/799,573) tested positive.

CONCLUSIONS

The FOCUS program is a unique model that will identify best practices for HIV screening and linkage to care.

Availability of insurance linkage programs in U.S. Emergency departments

INTRODUCTION

As millions of uninsured citizens who use emergency department (ED) services are now eligible for health insurance under the Affordable Care Act, the ED is ideally situated to facilitate linkage to insurance. Forty percent of U.S. EDs report having an insurance linkage program. This is the first national study to examine the characteristics of EDs that offer or do not offer these programs.

METHODS

This was a secondary analysis of data from the National Survey for Preventive Health Services in U.S. EDs conducted in 2008-09. We compared EDs with and without insurance programs across demographic and operational factors using univariate analysis. We then tested our hypotheses using multivariable logistic regression. We also further examined program capacity and priority among the sub-group of EDs with no insurance linkage program.

RESULTS

After adjustment, ED-insurance linkage programs were more likely to be located in the West (RR= 2.06, 95% CI = 1.33 - 2.72). The proportion of uninsured patients in an ED, teaching hospital status, and public ownership status were not associated with insurance linkage availability. EDs with linkage programs also offer more preventive services (RR = 1.87, 95% CI = 1.37-2.35) and have greater social worker availability (RR = 1.71, 95% CI = 1.12-2.33) than those who do not. Four of five EDs with a patient mix of ≥25% uninsured and no insurance linkage program reported that they could not offer a program with existing staff and funding.

CONCLUSION

Availability of insurance linkage programs in the ED is not associated with the proportion of uninsured patients served by an ED. Policy or hospital-based interventions to increase insurance linkage should first target the 27% of EDs with high rates of uninsured patients that lack adequate program capacity. Further research on barriers to implementation and cost effectiveness may help to facilitate increased adoption of insurance linkage programs.

Is self-perceived HIV risk congruent with reported HIV risk among traditionally lower HIV risk and prevalence adult emergency department patients? Implications for HIV testing

Because reliance on patients' self-perceived risk for HIV might mislead emergency department (ED) clinicians on the need for HIV testing, we aimed to measure congruency between self-perceived and reported HIV risk in a traditional lower prevalence, lower-risk cohort. A random sample of 18- to 64-year-old patients at a large academic urban ED who were by self-report not men-who-have-sex-with-men (MSM) or injection-drug users (IDUs) were surveyed regarding their self-perceived and reported HIV risk. Sixty-two percent of participants were white non-Hispanic, 13.8% Black, and 21.2% Hispanic; and 66.9% previously had been tested for HIV. Linear regression models were constructed comparing self-perceived to reported HIV risk. Among the 329 female ED patients, 50.5% perceived that they were "not at risk" for HIV, yet only 10.9% reported no HIV risk behaviors, while among the 175 male ED patients, 50.9% perceived that they were "not at risk" for HIV, yet only 12.6% reported no HIV risk behaviors. Only 16.9% of women and 15.7% of men who had no self-perceived risk for HIV also reported no HIV risk behaviors. Multivariable linear regression demonstrated a weak relationship between self-perceived and reported risk. Congruency between self-perceived risk and reported HIV risk was low among these non-MSM, non-IDU ED patients.
