Background Despite the reduction of HIV mother-to-child transmission, there are concerns regarding transmission rate in the breastfeeding period. We describe the routine uptake of 6 or 10 (6/10) weeks, 9 months and 18 months testing, with and without tracing, in a cohort of infants who received HIV PCR testing at birth (birth PCR) (with and without point of care (POC) testing) in a peri-urban primary health care setting in Khayelitsha, South Africa. Methods In this cohort study conducted between November 2014 and February 2018, HIV-positive mothers and their HIV-exposed babies were recruited at birth and all babies were tested with birth PCR. Results of routine 6/10 weeks PCR, 9 months and 18 months testing were followed up by a patient tracer. We compared testing at 6/10 weeks with a subgroup from historical cohort who was not tested with birth PCR. Results We found that the uptake of 6/10 weeks testing was 77%, compared to 82% with tracing. When including all infants in the cascade and comparing to a historical cohort without birth testing, we found that infants who tested a birth were 22% more likely to have a 6/10 weeks test compared to those not tested at birth. There was no significant difference between the uptake of 6/10 weeks testing after birth PCR POC versus birth PCR testing without POC. Uptake of 9 months and 18 months testing was 39% and 24% respectively. With intense tracing efforts, uptake increased to 45% and 34% respectively. Conclusion Uptake of HIV testing for HIV-exposed uninfected infants in the first 18 months of life shows good completion of the 6/10 weeks PCR but suboptimal uptake of HIV testing at 9 months and 18 months, despite tracing efforts. Birth PCR testing did not negatively affect uptake of the 6/10 weeks HIV test compared to no birth PCR testing.

AbstractIntroductionHigh rates of pre-treatment loss to care among persons diagnosed with HIV persist. Linkage to care can be improved through active digitally-based surveillance. Currently, record-keeping for HIV diagnoses in South Africa is paper-based. Aggregated testing data are reported routinely, and only discordant findings result in a specimen being tested at a laboratory and digitised.MethodsThe Western Cape Province in South Africa has a Provincial Health Data Centre (PHDC) where person-level routine data are consolidated in a single database, leveraging the existence of a unique patient identifier. To facilitate improved surveillance, a pre-carbonated point-of-care test (PoCT) form was piloted, where one copy was routed to the centralised laboratory and digitised for PHDC inclusion. We evaluated the utility of the intervention using cross-sectional and retrospective cohort analyses, as well as comparisons with reported aggregate data.ResultsFrom May 2017 to June 2018, 11337 digitised point-of-care HIV testing records were linked to the PHDC. Overall, 96% of records in the aggregate dataset were digitised, with 97% linked to the PHDC. Of those tested, 79% were female (median age 27 years). Linkage demonstrated that 51.3% of patients testing HIV-positive were retesting. Of those truly newly diagnosed, 81% were linked to HIV care and 25% were initiated on antiretroviral therapy immediately.ConclusionDigitisation of PoCT results is feasible and provides individuated HIV testing data to assist in linkage to care and in differentiating newly diagnosed patients from positive patients retesting. Actionable and accurate data can improve the measurement of performance towards the UNAIDS 90-90-90 targets.

ObjectivesHIV point-of-care testing (POCT) has been available in Manitoba since 2008. This study evaluated the effectiveness of POCT at identifying individuals with previously unknown HIV status, its effects on clinical outcomes and the characteristics of the populations reached.MethodsA retrospective database review was conducted for individuals who received HIV POCT from 2011 to 2014. Time to linkage to care and viral load suppression were compared between individuals who tested positive for HIV using POCT and controls identified as positive through standard screening. Testing outcomes for labouring women with undocumented HIV status accessing POCT during labour were also assessed.Results3204 individuals received POCT (1055 females (32.9%) and 2149 males (67.1%)), being the first recorded HIV test for 2205 (68.8%). Males were more likely to be targeted with POCT as their first recorded HIV test (adjusted OR (AOR) 1.40). Between the two main test sites (Main Street Project (MSP) and Nine Circles Community Health Centre), MSP tested relatively fewer males (AOR 0.79) but a higher proportion of members of all age groups over 30 years old (AOR 1.83, 2.51 and 3.64 for age groups 30–39, 40–49 and >50, respectively). There was no difference in time to linkage to care (p=0.345) or viral load suppression (p=0.405) between the POCT and standard screening cohorts. Of 215 women presenting in labour with unknown HIV status, one was identified as HIV positive.ConclusionsPOCT in Manitoba has been successful at identifying individuals with previously unknown HIV-positive status. Demographic differences between the two main testing sites support that this intervention is reaching unique populations. Given that we observed no significant difference in time to clinical outcomes, it is reasonable to continue using POCT as a targeted intervention.MeSH termsHIV infection; rapid HIV testing; vertical infectious disease transmission; community outreach; service delivery; marginalised populations.

Abstract Background There are 1.14 million people infected with human immunodeficiency virus (HIV) in the United States, and only about 86% are diagnosed. HIV diagnosis is the first step to care and expanded testing is essential to reduce transmission. Individuals with undiagnosed HIV have a transmission rate 3.5 times higher than those aware of their infection. Individuals seeking testing and treatment for sexually transmitted infections (STIs) represent a higher risk population for HIV infection. Despite revised Centers for Disease Control and Prevention (CDC) recommendations to expand HIV testing in healthcare settings, testing remains low. A significant obstacle to expanded testing, especially in emergency departments (EDs), is concern about ensuring appropriate HIV test tracking and follow-up. Methods We performed a retrospective chart review of patients presenting with symptoms of an STI between January 1, 2015 and July 8, 2019 at eight Beaumont Health EDs in Southeast Michigan. De-identified data was collected from the electronic health record (EHR) for patients aged 10 and older who had testing for one or more STIs including gonorrhea, syphilis, and chlamydia. Patients were evaluated for concurrent HIV testing during the encounter, and patients known to be HIV infected were excluded. Results Of 32,640 encounters during which patients not known to be HIV infected were tested for STIs, only 68 (0.21%) included HIV antibody/antigen screening. Of those tested, only one (1.47%) returned reactive. The remaining 67 screenings returned non-reactive. Applying only 10% of this diagnosis rate to the total number of STI encounters suggests an opportunity to diagnose 47 additional individuals; applying 50% of this rate and the corresponding value is 239 individuals. Conclusion These results highlight the need for expanded HIV screening in EDs. Systematic HIV test tracking and follow-up removes this burden from ED providers and enables expanded HIV testing in these settings. Disclosures All Authors: No reported disclosures

Background. A formative assessment of the implementation of HIV testing and counseling (HTC) at school showed high acceptability and willingness to test among learners. However, the success of the proposed HTC depends on the support and acceptability of key stakeholders, including the parents. The aim of the study was to assess the opinions and acceptability of the implementation of HTC at school among parents of adolescents in high school.Methods. This was a cross-sectional household survey conducted with parents of adolescents attending high schools in educational districts in North West and Gauteng provinces, South Africa.Results. A total of 804 parents participated, and 548 (68.3%) were biological mothers, 85 (10.6%) were fathers, and the remaining were other relatives including grandmothers. Almost all (n=742, 92.9%) parents were in support of implementation and provision of HTC at school, 701 (87.7%) would allow their children to be tested at school, 365 (46%) felt that parental consent was not needed to test at school, and 39.4% preferred to receive the HIV test results with their children.Conclusion. Parents accept the roll-out of an HTC program at school and have a role to play in supporting children who test positive for HIV.

Abstract Background Mobile HIV testing approaches are a key to reaching the global targets of halting the HIV epidemic by 2030. Importantly, the number of clients reached through mobile HIV testing approaches, need to remain high to maintain the cost-effectiveness of these approaches. Advances in rapid in-vitro tests such as INSTI® HIV-1/HIV-2 (INSTI) which uses flow-through technologies, offer opportunities to reduce the HIV testing time to about one minute. Using data from a routine mobile HTS programme which piloted the use of the INSTI point-of-care (POC) test, we sought to estimate the effect of using a faster test on client testing volumes and the number of people identified to be living with HIV, in comparison with standard of care HIV rapid tests. Methods In November 2019, one out of four mobile HTS teams operating in Ekurhuleni District (South Africa) was randomly selected to pilot the field use of INSTI-POC test as an HIV screening test (i.e., the intervention team). We compared the median number of clients tested for HIV and the number of HIV-positive clients by the intervention team with another mobile HTS team (matched on performance and area of operation) which used the standard of care (SOC) HIV screening test (i.e., SOC team). Results From 19 to 20 December 2019, the intervention team tested 7,403 clients, and the SOC team tested 2,426 clients. The intervention team tested a median of 442 (IQR: 288–522) clients/day; SOC team tested a median of 97 (IQR: 40–187) clients/day (p<0.0001). The intervention team tested about 180 more males/day compared to the SOC team, and the median number of adolescents and young adults tested/day by the intervention team were almost four times the number tested by the SOC team. The intervention team identified a higher number of HIV-positive clients compared to the SOC team (142 vs. 88), although the proportion of HIV-positive clients was lower in the intervention team due to the higher number of clients tested. Conclusions This pilot programme provides evidence of high performance and high reach, for men and young people through the use of faster HIV rapid tests, by trained lay counsellors in mobile HTS units.

Abstract Background: Transmission of HIV in South Africa continues to be high due to a large proportion of individuals living with undiagnosed HIV. Uptake of HIV testing is influenced by a multitude of factors including the patient’s knowledge and beliefs about HIV. Methods: This study sought to quantify the impact of knowledge and attitudes on HIV testing acceptance in an emergency department by co-administering a validated HIV knowledge and attitudes survey to patients who were subsequently offered HIV testing. Results: During the study period 223 patients were interviewed and offered HIV testing. Individuals reporting more negative overall attitudes (p = 0.006), higher levels of stigma to HIV testing (p<0.001), and individuals who believed their test was confidential (p<0.001) were more likely to accept an HIV test. Conclusions: Interventions focused on improving patient perceptions around testing confidentiality will likely have the greatest impact on testing acceptance in the emergency department.

Objective: HIV testing is the only method to confirm people infected with HIV. There are many models providing HIV testing services. HIV testing cost is an important component for the investment and strategic direction of policies and programs on HIV. This paper describes HIV testing costs of HIV confirmatory testing by using three rapid diagnostic tests at district level (POCT- Point of Care testing). Methods: cross-sectional study design was employed, costs are calculated using the cost-allocation method based on the proportion of resources used for the personnel, investment such as infrastructure and equipments, routine operational costs including test kits and consumable supplies, administration and training, fuel costs using for HIV testing in the laboratory, transporting the sample to province for HIV positived confirmation and HIV confirmatory test at the province. Five district health centers (DHC) thực hiện mô hình can thiệp POCT HIV were studied, HIV tests were conducted for 4,636 clients in 2016. Results : 201 HIV positive cases were detected; after implementing the POCT model to confirm HIV status at these five DHCs, the cost per HIV screening test case is 7,4 USD on average; and cost per an HIV comfirmatory test is 206,8 USD. Conclusion: Applying the POCT model of HIV helps reducethe cost of HIV testing because of saving cost for sample transportion and implementing confirm HIV detected more in provincal standard laboratory. It should be expanded to use especially limitted resource settings in Vietnam Keywords: HIV, HIV test, POCT, cost

Background Increasing the frequency of HIV testing in men who have sex with men (MSM) will reduce the incidence of HIV. Trends in HIV testing among MSM in Melbourne, Australia over the last 11 years have been investigated. Methods: A retrospective study was conducted using electronic medical records of the first presentation of MSM who attended the Melbourne Sexual Health Centre between 2003 and 2013. Factors associated with HIV testing (year, demographic characteristics and sexual practices) were examined in multivariable logistic regression analyses. Jonckheere–Terpstra tests were used to examine the significance of trends in the mean time since the last HIV test. Results: Of 17 578 MSM seen; 13 489 attended for the first time during the study period. The proportion of first attendances who had previously tested and reported a HIV test in the last 12 months increased from 43.6% in 2003 to 56.9% in 2013 (adjusted ptrend = 0.030), with a corresponding decrease in median time since the last HIV test from 19 months [interquartile range (IQR) 6–42] in 2003 to 10 months (IQR4–24) in 2013 (ptrend <0.001). The proportion of high-risk MSM (who reported unprotected anal intercourse and/or >20 partners in 12 months) who reported an HIV test in the last 12 months was unchanged (ptrend = 0.242). Conclusions: Despite HIV testing becoming more frequent, the magnitude of change over the last decade is insufficient to substantially reduce HIV incidence. A paradigm shift is required to remove barriers to testing through strategies such as point-of-care rapid testing or access to testing without seeing a clinician.

Background. We evaluated whether a pilot program providing point-of-care (POC), but not rapid, CD4 testing (BD FACSCount) immediately after testing HIV-positive improved retention in care.Methods. We conducted a retrospective record review at the Themba Lethu Clinic in Johannesburg, South Africa. We compared all walk-in patients testing HIV-positive during February, July 2010 (pilot POC period) to patients testing positive during January 2008–February 2009 (baseline period). The outcome for those with a≤250cells/mm3when testing HIV-positive was initiating ART<16weeks after HIV testing.Results. 771 patients had CD4 results from the day of HIV testing (421 pilots, 350 baselines). ART initiation within 16 weeks was 49% in the pilot period and 46% in the baseline period. While all 421 patients during the pilot period should have been offered the POC test, patient records indicate that only 73% of them were actually offered it, and among these patients only 63% accepted the offer.Conclusions. Offering CD4 testing using a point-of-care, but not rapid, technology and without other health system changes had minor impacts on the uptake of HIV care and treatment. Point-of-care technologies alone may not be enough to improve linkage to care and treatment after HIV testing.

Poor knowledge and adherence to point-of-care (POC) HIV testing standards have been reported in rural KwaZulu-Natal (KZN), a high HIV prevalent setting. Improving compliance to HIV testing standards is critical, particularly during the gradual phasing out of lay counsellor providers and the shifting of HIV testing and counselling duties to professional nurses. The main objective of this study was to identify priority areas for development of POC diagnostics curriculum to improve competence and adherence to POC diagnostics quality standards for primary healthcare (PHC) nurses in rural South Africa. Method: PHC clinic stakeholders were invited to participate in a co-creation workshop. Participants were purposely sampled from each of the 11 KwaZulu-Natal Districts. Through the Nominal Group Technique (NGT), participants identified training related challenges concerning delivery of quality point of care diagnostics and ranked them from highest to lowest priority. An importance ranking score (scale 1–5) was calculated for each of the identified challenges. Results: Study participants included three PHC professional nurses, one TB professional nurse, one HIV lay councilor, one TB assistant and three POC diagnostics researchers, aged 23–50. Participants identified ten POC diagnostics related challenges. Amongst the highest ranked challenges were the following:absence of POC testing Curriculum for nurses, absence of training of staff on HIV testing and counselling as lay counsellor providers are gradually being phased out,. absence of Continuous Professional Development opportunities and lack of Staff involvement in POC Management programs. Conclusion: Key stakeholders perceived training of PHC nurses as the highest priority for the delivery of quality POC diagnostic testing at PHC level. We recommend continual collaboration among all POC diagnostics stakeholders in the development of an accessible curriculum to improve providers’ competence and ensure sustainable quality delivery of POC diagnostic services in rural PHC clinics.
