Human Immunodeficiency Virus (HIV) is one of the transmitted infection through blood transfusion. Chemiluminescence immunoassay for HIV testing is performed to ensure the safety and quality of blood product that released. Purpose of the study to identify the result of Chemiluminescence Immunoassay methode for HIV testing to blood donor’s characteristic based on gender, age, blood group, HIV titer, and donation location. The design of this research is descriptive retrospective. There is 11 (0,8%) reactive blood bag and 1.289 (99,2%) blood bag non reactive to HIV, reactive blood bag based of gender is 8 (72,7%) blood bag from male donors and 3 (27,3%) blood bag from female donors. Based on donors age, mostly reactive result are from 41-70 years old is 4 (36,4%) donors, and the fewest is from (under) 19 years old is 1 (9,1%) donors. The majority based on blood group is B Rh+ is 4 (36,4%) donors. The majority based on HIV titer is low titer, 1,0-2,0 is 7 (63,6%) donors. Based on donation location, mostly from mobile unit (MU) is 8 (72,7%) donors over 11 donors with HIV reactive. Conclusion of this study is donors gender, donors age, and donation location had a significant influence on reactive result of HIV testing.

Abstract Background In our urban, underserved patient population, Human Immunodeficiency Virus (HIV) is hyper-endemic, and HIV screening is frequently performed. Although HIV screening tests have high specificity, false positives can occur. Numerous reasons for false positive testing have been cited, including vaccinations, autoimmune diseases, and viral infections. In 2019, Philadelphia experienced a large Hepatitis A outbreak, during which time false positive HIV screening tests were discovered. Our aim was to further describe these patients who had been diagnosed with acute Hepatitis A infection and in whom false positive HIV testing had occurred. Methods We conducted a retrospective chart review of adult patients admitted to our hospital between January 2017 and December 2019 who had a positive Hepatitis A Virus (HAV) IgM. Demographics, HIV tests, viral hepatitis tests, and liver tests were recorded. False positive HIV was defined as a positive HIV screen (p24 antigen and HIV-1 and 2 antibody combo), followed by a negative differentiation assay for HIV-1 and 2 antibodies, combined with a negative HIV PCR. Results A total of 156 unique patients were found to have acute HAV, with 138 cases identified in 2019. Of these, 3 patients had confirmed false positive HIV testing, and 1 patient had suspected false positive HIV testing (HIV-2 differentiation assay indeterminate, with very low local prevalence of HIV-2), for a false positive test rate of 2.6% (4/156). Ages ranged from 36-47 years, 3 were male, and 2 were persons who injected drugs (PWID). Three patients had prior negative HIV testing. Two patients had fevers during admission, but none of the four were febrile at the time of HIV test collection. Three patients had elevated transaminases, and two had abnormal coagulation testing. Coinfection with Hepatitis C was found in three patients. One patient had follow-up HIV testing performed, which was negative. Conclusion To our knowledge, this is the first report of false positive HIV testing related to acute HAV. Prevalence of false positives was low, but awareness can facilitate patient counseling. With low sample size, conclusions cannot be drawn about risk factors related to false positive testing. Disclosures All Authors: No reported disclosures

Treatment of human immunodeficiency virus(HIV) in cancer patients improves outcomes and reduces transmission of this oncogenic virus. HIV testing rates of cancer patients are similar to the general population (15-40%), despite the association with cancer. Our aim was to increase HIV screening in the Emergency Department(ED) of a comprehensive cancer center through a quality initiative. Testing increased significantly during the intervention (p<0.001; 0.15/day to 2.69/day). Seropositive HIV rate was 1.4% (12/852), with incidence of 0.3%. All patients were linked to care. Incident cases were between 36 and 55 years of age. Barriers encountered included confusion regarding the need for written consent for HIV testing, failure to consider ordering the test, and concerns regarding linkage to care.

Abstract Background Emergency Departments (EDs) are important sites for HIV testing. However, there is little guidance on how best to implement HIV testing in the ED. The purpose of this study was to evaluate HIV screening practices of high-risk individuals presenting to an ED in the absence (ED1) and in the presence (ED2) of an established HIV testing program within the same academic hospital. Methods We performed a retrospective chart review of all individuals 18 years or older presenting to either ED between January 1, 2016 and December 31, 2018. High-risk of HIV infection was determined by receipt of bacterial sexually transmitted infection (STI) testing for Neisseria gonorrhoeae or Chlamydia trachomatis. The primary outcome was receipt of any HIV test in the ED. Overall proportions of patients tested for HIV at the same time of STI testing were compared between sites by chi-square test. Predictors of HIV testing were analyzed by logistic regression. Results During the study period, 7,956 individuals received STI testing at ED1 and 10,815 received STI testing at ED2. The majority of individuals receiving STI testing at both sites were female, 81.2% at ED1 and 66.4% at ED2 (P <0.001). Only 4.0% of individuals received HIV testing at ED1 compared with 47.4% at ED2 (P <0.001). Individuals were significantly more likely to receive HIV testing at the time of STI testing in the ED with an HIV testing program (aOR 19.66, 95% CI 17.28–22.37). In the ED without an HIV testing program, individuals were more likely to receive HIV testing if they were male (aOR 3.57, 95% CI 2.78–4.55) and less likely if they were black (aOR 0.57, 95% CI 0.50–0.97). In the ED with an HIV testing program, individuals were more likely to receive HIV testing if they were male (aOR 2.17, 95% CI 1.92–2.44) and more likely if they were black (aOR 1.74, 95% CI 1.37–2.20). Conclusion Overall, the presence of an HIV testing program in the ED significantly increased the probability that individuals would receive an HIV test at the time of bacterial STI testing and mitigated disparities in care. The results of this study will help guide ongoing interventions to improve HIV screening among high-risk individuals in the emergency department. Disclosures All authors: No reported disclosures.

Background: Human immunodeficiency virus (HIV) infection continues to expand worldwide and a significant proportion of infection is still undiagnosed. Recent studies have addressed the impact and feasibility of ‘opt-out’ HIV screening in Emergency Departments (EDs) in urban settings at high HIV prevalence, whereas little is known about the yield of implementing ‘targeted’ HIV testing especially in low-prevalence areas. Objective: The present study undertakes a scoping review of research carried out on the implementation of targeted HIV screening in adult EDs to determine the impact, feasibility and acceptability of HIV testing in different HIV prevalence settings. Design: Online databases (EMBASE, MEDLINE) were used to identify papers published between 2000 to 2020. A threeconcept search was employed with HIV (HIV, Human immunodeficiency virus infection, HIV infections), targeted testing (Target, screening or testing) and emergency medicine (Emergency Service, emergency ward, A&E, accident and emergency or Emergency Department) (28th February 2020). Only full-text articles written in English, French, Spanish or Italian and using impact and/or feasibility and/or acceptability of the program as primary or secondary outcomes were analysed. Results: The search returned 416 articles. Of these, 12 met inclusion criteria and were included in the final review. Most of the included studies were carried out in the United States (n=8; 67%) and in areas of high HIV prevalence (n=11; 92%). Three (20%) were randomized control studies. While the rate of newly diagnosed HIV cases varied widely (0.03-2.2%), likely due to methodological heterogeneity between studies, the linkage of new HIV diagnosis was often high (80-100%) and median CD4+ cell count was always greater than 200 cells per microliter. Targeted HIV screening was found to be cost-effective (out of 2 studies) and well accepted by participants (out 2 studies). Conclusions: Targeted HIV screening at the ED can be impactful, feasible and well accepted, but often requires extra funding and staff. Most previous work has focused on areas of high disease prevalence.

Abstract Background Provider-initiated HIV testing and counseling (PITC) is a recommended approach to screen for HIV to all pregnant women during antenatal care (ANC) visits, and all with HIV positive results have to be enrolled into prevention of mother-to-child transmission of HIV (PMTCT) program. However, little is known about the relationship between facility readiness and the uptake of PITC to pregnant women attending ANC in Tanzania. Therefore, this study assessed whether the facility readiness promotes the uptake of PITC to the pregnant women attending ANC for the purpose of improving the PMTCT interventions in Tanzania. Methods This study analyzed data for health facilities obtained from the 2014–2015 Tanzania service provision assessment survey. The Primary outcome measure was a composite variable (with score of 0–5) in which its higher scores indicates provision of high-quality of PITC. Also, facilities scored higher in the PMTCT service readiness index were considered to have high readiness to provide PMTCT services. In Poisson regression analyses, a series of models were fitted to assess whether there is an association between provision of high-quality of PITC and facility readiness. In all statistical analysis, a P < 0.05 was considered significant. Results Out of 1853 included first-visit ANC consultations, only about one-third of pregnant women received all five components required for PITC. The mean percentage of PMTCT readiness score was moderate 63.96 [61.32–66.59]%. In adjusted model, we found that facility with high readiness to provide PMTCT services was significantly associated with the provision of high-quality of PITC (model 2: [β = 0.075, P = 0.00]). Conclusion In order to increase high-quality of PITC services, efforts should be made to improve the PMTCT facility readiness by increasing availability of trained staffs, diagnostic tools, and ARTs among health facilities in Tanzania.
