Abstract Given the clinical and public health benefits of routine Human Immunodeficiency Virus (HIV) testing in the emergency department (ED) and Centers for Disease Control and Prevention recommendations, Maricopa Medical Center, as part of Maricopa Integrated Health System, started Test, Educate, Support, and Treat Arizona (TESTAZ) and became the first and, to-date, only hospital in Arizona to implement routine, non-targeted, opt-out, rapid HIV screening in the ED. The authors describe the implementation of a universal, routine, opt-out HIV screening program in the adult ED of an urban safety-net hospital serving under-served populations, including the uninsured and under-insured. Through a controlled and collaborative process, the authors integrated custom documentation elements specific to HIV screening into the triage/intake process, implemented and utilized clinical decision support tools to guide clinicians in each step of the process, and used electronic data collection and reporting to drive new screening protocols that led to a significant increase in overall HIV testing rates.

The Impact

Abstract Background The Emergency Department (ED) at Memorial Hermann Hospital (MHH) - Texas Medical Center (TMC), Houston, Texas has a long established screening program targeted at detection of HIV infections. The impact of the COVID-19 pandemic on this screening program is unknown. Methods The Routine HIV screening program includes opt-out testing of all adults 18 years and older with Glasgow score > 9. HIV 4th generation Ag/Ab screening, with reflex to Gennius confirmatory tests are used. Pre-pandemic (March 2019 to February 2020) to Pandemic period (March 2020 to February 2021) intervals were compared. Results 72,929 patients visited MHH_ED during the pre-pandemic period and 57,128 in the pandemic period, a 22% decline. The number of patients tested for HIV pre-pandemic was 9433 and 6718 pandemic, a 29% decline. When the pandemic year was parsed into first and last 6 months interval and compared to similar intervals in the year pre pandemic, 39% followed by 16% declines in HIV testing were found. In total, 354 patients were HIV positives, 209, (59%) in the pre-pandemic and 145 (41%) in the pandemic period.The reduction in new HIV infections found was directly proportional to the decline in patients visiting the MHH-ED where the percent of patients HIV positive was constant across intervals (2.21% vs 2.26%). Demographic and outcome characteristics were constant across the compared intervals. Conclusion The COVID -19 pandemic reduced detection of new HIV infections by screening in direct proportion to the reduction in MHH-ED patient visits. The impact of COVID-19 pandemic decreased with duration of the pandemic. Disclosures All Authors: No reported disclosures

Start Date

Abstract Background In 2016, MetroHealth System (MHS) launched the FOCUS (Frontlines of Communities in the United States) project to routinize HIV testing in the emergency department (ED). Before 2016, clinical decision support (CDS) for HIV testing was not in place, nor was there a policy to support the importance of opt-out, nontargeted screening. The purpose of this study was to outline the progress of HIV testing after the integration of CDS, as well as describe the implementation challenges, and how certain events impacted HIV testing. Methods HIV testing data from MHS EDs were collected from October 1, 2015 to March 31, 2019 and graphed into a run chart. The dataset was mapped with the following events: project start date, ED testing begins (without CDS), CDS implementation, the staffing of the ED Testing Coordinator (EDTC), and optimization of CDS (Figure 1). To determine whether observed variation in the dataset is due to random or special cause variation, these run chart rules were applied: Run, Shift (Figure 2), and Trend. Results There were 42 data points and 4 runs. With 42 points, the lower limit of runs was 16 and the upper limit of runs was 28. This signals that one or more special cause variations were present. A total of three distinct shifts were observed indicating special cause variation. The run chart did not include any downward or upward trends. Testing increased as much as 3971% (7 tests in October 2015 vs. 285 tests in March 2018). Conclusion HIV testing increased from 7 tests to 86 tests (Shift 1). This coincided with establishment of an ED testing policy in April 2016. Testing increased to 266 tests in October 2016 (Shift 2). This directly related to implementation of CDS in the ED. December 2017 displayed the lowest testing with 117 tests. This was due to lack of policy awareness, and to the rarely-visited location of the HIV screening tool during the triage process. Staff was re-educated and the HIV screening tool was moved to a more visible location. This resulted in 227 tests in February 2018, and was followed by the highest testing month with 285 tests (Shift 3). Continued challenges prohibit sustained upward trends in ED testing. A control chart may be the appropriate next step to identify new control limits Disclosures All authors: No reported disclosures.

Objective. To determine the prevalence of occult HIV infection in patients who decline routine HIV testing in an urban emergency department.Design, Setting, and Patients. Discarded blood samples were obtained from patients who had declined routine ED HIV testing. After insuring that the samples came from patients not known to be HIV positive, they were deidentified, and rapid HIV testing was preformed using 5 μL of whole blood.Main Outcome Measures. The prevalence of occult HIV infection in those who declined testing compared with prevalence in those who accepted testing.Results. 600 consecutive samples of patients who declined routine HIV screening were screened for HIV. Twelve (2%) were reactive. Over the same period of time, 4845 patients accepted routine HIV testing. Of these, 35 (0.7%) were reactive. The difference in the prevalence of HIV infection between those who declined and those who accepted testing was significant (). The relative risk of undetected HIV infection in the group that declined testing was 2.74 times higher (95% CI 1.44–5.18) compared with those accepted testing.Conclusion. The rate of occult HIV infection is nearly three-times higher in those who decline routine ED HIV testing compared with those who accept such testing. Interventions are urgently needed to decrease the opt-out rate in routine ED HIV testing settings.

Abstract Background In November 2014, the University of Illinois Hospital (UI Health) introduced an electronic medical record (EMR)-driven HIV screening program in the emergency department (ED). In October 2016, our hospital laboratory introduced “Fifth-generation” HIV testing using the Bio-Rad BioPlex 2200 HIV Antigen/Antibody diagnostic assay. Fifth-generation HIV testing has the advantage of separately detecting and reporting HIV antibody and HIV-1 p24 antigen. Although the literature and manufacturer report high sensitivity and specificity of this test, we encountered higher than expected rates of false-positive tests during the introduction of this test. Methods We retrospectively reviewed the results of our ED HIV screening program from October 2016 to March 2019 to describe the outcomes of HIV testing, determine the rates of false-positive HIV tests and determine if false-positive rates were temporally clustered. We also investigated various potential causes of higher than expected false positives including pre-analytical and analytical error. We defined a false-positive test as a repeatedly reactive initial HIV antigen and/or HIV-1 antibody result with a subsequent negative or indeterminate HIV-1/2 antibody differentiation immunoassay and negative HIV-1 nucleic amplification test. Results During the review period, out of a total of 17,385 HIV tests which were performed, 85 tests were confirmed positive and 27 were false positives. This represents an HIV prevalence of 0.5%. Eighteen of the 27 false positives occurred during an 8 month period between October 2016 and April 2017 (see Figure 1). During our investigation of potential causes of the false-positive tests, we discovered that a reagent lot for the test was changed in June 2017 which resulted in a significant decrease in the false-positive rate (0.33% to 0.07%). Conclusion We provide data which suggests that a reagent lot may have been the cause of higher than expected false-positive tests for HIV testing. Monitoring of testing outcomes during implementation of a routine HIV testing program can help identify potential root causes of false-positive tests.
