Caregivers’ experiences of accessing HIV Early Infant Diagnosis (EID) services and its barriers and facilitators, India

BackgroundIndia has rolled out Early Infant Diagnosis (EID) program for HIV infection in all states. EID program consists of testing of Infants exposed to HIV periodically over 18 months of age which is a multi-step complex testing cascade. Caregivers represent the primary beneficiary of EID program i.e., infants exposed to HIV and face multiple challenges to access EID services. As part of national EID program outcome assessment study, this study narrates caregivers’ perspectives on barriers and facilitators to access and utilize EID services.MethodsThe study was conducted in 31 integrated counselling and testing centres (ICTCs) located in 11 high burden HIV states. A total of 66 in-depth interviews were conducted with caregivers’ of infants enrolled in EID program. Thematic analysis was carried out to help identify themes underlying barriers and facilitators to access EID services and utilization from caregivers’ perspectives.ResultsThe stigma and discrimination prevalent in society about HIV remains a key demand side (caregiver-level) barrier. Non-disclosure or selective disclosure of HIV status led to missed or delayed EID tests and delayed HIV diagnosis and initiation of Anti-Retroviral Therapy (ART) for infants exposed to HIV. On supply side (health system-level), accessibility of healthcare facility with EID services was reported as a key barrier. The distance, time and cost were key concerns. Many caregivers faced difficulties to remember the details of complex EID test schedule and relied on a phone call from ICTC counsellor for next due EID test. Delayed EID test results and lack of communication of test results to caregiver were reported as primary barriers for completing the EID test cascade.DiscussionThe study reports caregiver-level and health system-level barriers and facilitators for access to EID services from the caregivers’ perspectives. While, decentralisation and single window approaches can improve the access, timely communication of test results to the caregiver also need to be built in with appropriate use of technology. A holistic intervention including PLHIV support networks and the peer-led support mechanisms would be useful to address societal factors.ConclusionThe study findings have high significance for developing program implementation strategies to improve access and to build right-based and patient-centred EID services.

Process Evaluation of Services for HIV-Infected Post-Partum Women and HIV-Exposed Infants in Primary Health Care Blantyre Malawi.

HIV testing among HIV-exposed infants (HEI) in Malawi is below global targets and, affected by low utilisation of health services after birth. We conducted a mixed methods evaluation of the implementation of services for early infant diagnosis (EID) of HIV against national guidelines in Blantyre, Malawi, to inform the development of strategies to improve EID services uptake. We estimated coverage of HEI enrolment in HIV care and HIV testing at 6 weeks through a retrospective data review. We qualitatively explored implementation gaps in EID services through process mapping of 8 mother-infant pairs (MIP); and investigated healthcare workers' (HCW) perspectives on the implementation gaps through group interviews with 16 HCWs. We analysed the quantitative data descriptively and conducted a thematic content analysis of qualitative data. Of 163 HEIs born at the study sites, 39 (24%) were enrolled in an HIV care clinic before post-natal discharge, and 85 (52%) received HIV testing by 6 weeks. The median time for MIP to receive EID services was 4 (1-8) hours. The implementation gaps observed during process mapping included: failure to identify and enrol HEI in HIV care clinic; lack of immunisation, counselling for HEI testing, HIV testing, drug refilling, and family planning; and different appointment dates for mother and infant. HCWs reported delays and gaps influencing optimal service provision including: lack of screening to identify MIP, limited supervision for student HCWs when providing services, inadequate capacity of point of care machines, challenges with integrating services, and role confusion. Use of unique identifiers for MIP and establishing a booking system to schedule appointments to suit point of care machine capacity were primary service improvement recommendations. This study identified suboptimal EID services in Malawi due to process, capacity, and system factors. Context-appropriate interventions accommodating systems thinking are needed to enhance service provision.

Predictors of Mothers Living with HIV Uptake of HIV Early Infant Diagnosis Services in Iringa District, Tanzania.

Uptake of HIV early infant diagnosis (HEID) among HIV-exposed infants is the key to timely initiation of Antiretroviral Treatment (ART). However, despite the availability of HEID services in Tanzania, its uptake is low. We aimed to determine predictors of mothers living with HIV' with HIV-exposed infants' uptake of HEID services in Iringa District, Tanzania. A health facility-based cross-sectional study was conducted in Iringa District from May to June 2023. Mothers with HIV-exposed infants were recruited in the study through a multistage sampling technique and interviewed using pre-tested structured questions. Logistic regression analysis was employed to determine potential predictors of HEID uptake. A total of 309 mothers with HIV-exposed infants participated in the study. About 78.3% of the HIV-exposed infants had initial DNA PCR for HEID within 6 weeks of age and 86.1% within 8 weeks. Most mothers had high perceived benefits on uptake of HEID with a mean score of 4.3, high perceived self-efficacy with a mean score of 3.8 and 2.7 perceived risk of HIV infection on their HIV-exposed infants on the 5 scale Likert scale with 5 showing the highest perceived benefit, self-efficacy and risk. High perceived self-efficacy and being a businesswoman were the predictors of uptake of HEID. The odds of self-efficacy on the uptake of HEID by 2.4 times (aOR 2.4 95% CI 1.6-3.2) within 6 weeks of age and 1.9 (aOR 1.9 95% CI 1.3-2.7) within 8 weeks. The odds of being a businesswoman were 0.4 for 6 weeks and 0.3 for 8 weeks (aOR 0.4 95% CI 0.2-0.8) and (aOR 0.3 95% CI 0.1-0.8) respectively. Over three-quarters of the HIV-exposed infants had initial DNA PCR for HEID testing as recommended. Perceived self-efficacy was the main factor influencing HEID uptake. These findings highlight the need for strengthening HIV-positive mother's self-efficacy for improved uptake of HEID services.

Prognostic factors influencing HIV-free survival among infants enrolled for HIV early infant diagnosis services in selected hospitals in Nairobi County, Kenya.

Despite being a preventable disease, pediatric HIV infection continues to be a public health concern due to the morbidity and mortality associated with the disease. Vertical transmission of HIV occurs when a mother living with HIV passes the virus to her baby during pregnancy, childbirth, or breastfeeding. Globally, the vertical transmission rate of HIV is 9% with sub-Saharan Africa accounting for 90% of these infections. In Kenya, the national vertical transmission rates of HIV stood at 11.5% by the end of 2018, with a target to reduce vertical transmission rates to below 5% and 2% in breastfeeding and non-breastfeeding infants respectively, by the end of 2021. To determine the prognostic factors influencing HIV-free survival among infants enrolled for HIV early infant diagnosis (EID) services in selected hospitals in Nairobi County, Kenya. A prospective cohort study design was adopted. HIV exposed infants were recruited at six weeks to determine HIV-free survival over 12 months follow up. Simple random sampling was used to select 166 infants and data were collected from the mothers using semi-structured interviewer-administered questionnaires. Log-rank tests were used to test for associations at the bi-variable level while Cox-proportional regression was used to analyze data at the multi-variable level, with the aid of STATA 14 software. Ethical approval was obtained from Kenya Medical Research Institute, Scientific Ethics Review Unit. The overall infant HIV incidence rate over one-year follow-up was 9 cases per 100 person-years (95% CI: 5.465-16.290). The failure event was defined as an infant with a positive PCR test during the study period with total failures being 13 (9.41%) over 12 months. Prognostic factors associated with poor infant HIV-free survival were young maternal age (18-24 years) and mothers with a recent HIV diagnosis of ≤ 2 years since a positive HIV diagnosis (HR 5.97 CI: 1.20, 29.58) and (HR 6.97 CI: 1.96, 24.76), respectively. Maternal prognostic factors associated with poor infant HIV-free survival were young maternal age (18-24 years) and recent maternal HIV diagnosis of ≤ 2 years since positive HIV diagnosis. The study recommended the development of an intervention package with more rigorous adherence counseling and close monitoring for young mothers, and mothers with recent HIV diagnoses.

Early infant diagnosis of HIV infection: a mixed-method study of uptake and challenges at primary health centers in Lagos State, Nigeria

IntroductionNigeria has a low uptake of early infant diagnosis (EID) of HIV despite its high pediatric HIV infection rate. Efforts to increase the EID of HIV have been limited by many factors. This research assessed EID uptake and challenges service providers experienced in providing routine care for HIV-exposed infants.MethodsThis is a mixed-method study at primary health centers (PHCs) in Lagos state, Nigeria. The quantitative component of the research was a review of the PMTCT Infant Follow-up Register at a purposive sample of 22 PHCs of Lagos State. The number of HIV-exposed infants (HEIs) returned for a dried blood sample (DBS) collection, date of collection, and the infant’s EID results for one year preceding the study were captured on Research Electronic Data Capture (RedCap). In-depth interviews were conducted with service providers purposively selected per participating PHC. Electronic transcripts were analyzed using MAXQDA 2020 (VERBI Software, 2019).ResultsTwenty-two Lagos State primary health centers participated in the research. Fifteen PHCs (68.2%) had PMTCT HIV counseling and Infant follow-up registers. Documentation of DBS sample collection was observed in 12 (54.6%) PHCs. Both DBS sample collection and EID results documentation were observed in only nine (40.9%) PHCs. In-depth interviews revealed both maternal and health systems’ challenges to EID. The denial of HIV status was the only maternal factor reported as a barrier against the use of EID services. Health systems challenges include unavailability of EID services, uncertainty regarding whether EID is performed in a facility, referral to secondary health facilities for EID services (leading to losses to follow-up), and delay in getting results of EID. Task-shifting of DBS collection by nurses was suggested as means to increase access to EID services.ConclusionsThere is a need to expand EID services and address women’s denial of HIV infection. Counseling women and linkage to available services are emphasized. Re-training of health workers on DBS collection and proper documentation of EID services were noted as key to improving the implementation of early infant diagnosis of HIV in the state.

Incorporating the HIV Infant Tracking System into standard-of-care early infant diagnosis of HIV services in Kenya: a cost-effectiveness analysis of the HITSystem randomised trial

The HITSystem efficacy trial showed significant improvements in early infant diagnosis retention, return and notification of infant test results, and earlier antiretroviral therapy (ART) initiation compared with standard-of-care early infant diagnosis services in Kenya. This study aimed to analyse data from the HITSystem trial to assess the cost-effectiveness of the intervention in Kenya. In this analysis, we extrapolated results from the HITSystem cluster randomised controlled trial to model early infant diagnosis outcomes and cost-effectiveness if the HITSystem was scaled up nationally in Kenya, compared with standard-of-care outcomes. We used a micro-costing method to collect cost data, which were analysed from a health-system perspective, reflecting the investment required to add HITSystem to existing early infant diagnosis services and infrastructure. The base model used to calculate cost-effectiveness was deterministic and calculated the progression of infants through early infant diagnosis. Differences in progression across study arms were used to establish efficacy outcomes. The number of life-years gained per infant successfully initiating ART were based on the Cost Effectiveness of Preventing AIDS Complications model in east Africa. HITSystem cost data were integrated into the model, and the incremental cost-effectiveness ratio was calculated in terms of cost per life-year gained. Sensitivity analyses were done using the deterministic model with triangular stochastic probability functions for key model parameters added. The number of life-years gained was discounted at 3% and costs were adjusted to 2021 values. The cost per life-year gained from the HITSystem was US$82·72. Total cost for national HITSystem coverage in Kenya was estimated to be around $2·6 million; covering 82 230 infants exposed to HIV at a cost of $31·38 per infant and a yield of 1133 infants receiving timely ART, which would result in 31 189 life-years gained. With sensitivity analyses, the cost per life-year gained varied from $40·13 to $215·05. 90% of model values across iterations ranged between $55·58 (lower 5% threshold) and $132·38 (upper 95% threshold). The HITSystem would be very cost-effective in Kenya and can optimise the return on the existing investment in the national early infant diagnosis programme.

Access, timeliness and retention for HIV testing under early infant diagnosis (EID) program, India

Early Infant Diagnosis of HIV infection services are crucial for managing the perinatally acquired HIV infection. Assessing the performance of the EID services and its underlying determinants is important for the National AIDS Control Program, India. The objectives of this study were to find out access to HIV testing, the timeliness of the testing cascade, and the proportion of HIV exposed infants who are followed up to 18 months for a definitive diagnosis of HIV. The study design was a mixed method. A total of 11 states accounting for 80% of HIV-positive pregnant women were selected. Program records from a total of 62 Integrated counselling and testing centres (ICTCs) served as the source of information. The qualitative component included interviews of program managers at the state and district level, service providers at the ICTC level, and caregivers of HIV exposed infants. In the sampled 62 ICTCs, 78% of the HIV exposed infants had at least one HIV test. Of the infants who had HIV tests, 50% had at first sample collected by 8 weeks of age. The median turnaround time from sample collection to DNA PCR testing was 36 (IQR 19–70) days and that to next sample collection in case of detection of virus in the first sample was 66 (IQR 55–116) days. At 18 months of age, 544 (62%) HIV exposed infants were retained in the EID testing cascade. A total of 30 infants were diagnosed with HIV at a median age of 421 (IQR 149–650) days. More than three fourth of the HIV exposed infants had access to early infant diagnosis (EID) services. Both demand and supply-side factors contribute to access, timeliness and retention and there is a need to address these factors.

Sustaining Early Infant Diagnosis of HIV During Coronavirus Disease 2019 Pandemic

To the Editors: Despite advances in prevention of mother to child transmission (PMTCT) of HIV, 160,000 new pediatric HIV infections were reported in 2020.1 Vertical transmission of HIV in Nigeria remains high at 22%, with 37,000 new infections among children 0–14 years annually.2 In Nigeria, access to early infant diagnosis (EID) has improved significantly; however, only 27% of HIV-exposed infants received an HIV test by 2 months of age in 2019.3 EID programs require mothers to bring their infants to the health facility for testing. However, the global coronavirus disease 2019 (COVID-19) pandemic movement restrictions necessitated changes to the PMTCT service delivery model for infant follow-up to ensure uninterrupted service delivery. Nigeria reported its first COVID-19 case on February 27, 2020.4 By March, a mandatory lock down with subsequent movement restrictions limited access to health facilities for nonemergency presentations including PMTCT services.4 The Reaching Impact Saturation and Epidemic (RISE) Control program, which currently provides comprehensive HIV prevention, care and treatment services to over 82,000 recipients of care, rapidly pivoted to a community service delivery model to ensure uninterrupted access to HIV services. To circumvent the challenges faced by mothers and caregivers in accessing health facilities during the COVID-19 lockdown period, RISE deployed trained nurses to collect dried blood spot (DBS) samples for HIV viral load and EID in the communities where children, infants and their caregivers live. EID samples were collected by trained nurses in the home and transported to the health facility for onward transportation to regional labs. When sample collection was not feasible in the home, caregivers were escorted to the nearest health facility for sample collection. Case managers also provided antiretroviral drug refills for recipients of care in the community including antiretroviral prophylaxis refills for infants. Prelock down (October 2019 to March 2020), RISE collected 690 samples of which 57% (393/690) were collected within 2 months of birth with average turnaround time of 30 days. Postlock down (April to September 2020), 634 samples were collected of which 60% (379/634) were within 2 months of birth while maintaining an average turnaround time of 34 days. Regarding actual tests done, prelock down tests were done for 75% of samples for infants <2 months (n = 295) with 1.0 % positivity rate, while postlock down, 77% (n = 291) were tested with 0.3% positivity. Early results from the RISE program have shown that DBS specimens for HIV diagnosis in infants can be safely collected at home while maintaining specimen integrity and delivery of results back to caregivers. Several adaptations have been made to HIV programming to improve service delivery for HIV-infected pregnant, breast-feeding women, infants, children and adolescents.4 We propose that HIV programs consider implementing home-based DBS collection to increase access to timely EID services for HIV-exposed infants both as an adaption during the COVID-19 pandemic and as an enduring solution thereafter.

Maternal and caretaker's knowledge of HIV infections and the existence and benefits of early infant diagnosis (EID) services at Kericho county referral hospital, Kenya.

This study was a cross-sectional analytical survey of the Maternal and caretaker's knowledge of HIV infections and the existence and benefits of early infant diagnosis (EID) services at Kericho county referral hospital in Kenya. Data was collected using pretested questionnaires administered to the postnatal HIV positive mothers and or caretakers of HIV exposed children. Data were analysed using SPSS software version 18.0. Moreover, it was presented using Chi-square and Logistic Regression analysis. Of the 254 respondents, 201 (79.1%) were biological mothers to the children; the rest were caretakers. The children were aged between 1 and 18 months, with a mean age of 9.62 months. Most respondents' knowledge of adult HIV infection is about what HIV is, routes of transmission, diagnosis and treatment. Knowledge of paediatric HIV infection was, however, inadequate with only 132 (52%) respondents who knew the approximate rate of HIV transmission from mother to child and 130 (51.2%) who knew about the availability of paediatric Antiretroviral (ARV) drugs. Both adult and paediatric HIV knowledge was better with an increasing level of education. The younger respondents were also more knowledgeable than, the older ones. Children who had utilised EID were only 75 (29.5%). In conclusion, EID knowledge is still lacking in Kericho County, and it influences the utilisation of these services. EID services and education on the availability should be decentralised where feasible. They should be included as an essential service at all levels of healthcare delivery to reach more children. Further research needs to be done on how to leverage HIV knowledge to increase the uptake of services and alleviate impediments to utilising services. Improving maternal education is strongly recommended, as it would enhance EID uptake.

Early Infant Diagnosis of HIV in Primary Health Care Centers

Background: Early diagnosis of HIV to identify infected children for early therapy is aimed at preventing high mortalities associated with child HIV infection. Early infant diagnosis (EID) intervention occurs across the three tiers of the Nigerian health care delivery system, including the primary health care centers (PHC). This study evaluates the implementation of early infant diagnosis of HIV in PHCs in a southern state of Nigeria. Methods: This was a cross-sectional descriptive study that took place between September and November 2019. Primary data were obtained from an interviewer-administered questionnaire on 120 health workers in six Local Government Areas (LGA) that were selected through a multi-stage, random sampling method. Secondary data were from the records of program implementation at the state headquarters of Ministry of Health and the PHCs. Results: A total of 116 (96.6%) health workers were interviewed; 17.2% were males, and 82.8% were females. More than two-thirds of respondents were aged between 41 and 60 years and 84.5% of them had worked in the PHC system for 11 years and above. Rural or urban location of the PHC, educational level of the health workers, and years of service in the PHC system did not have any significant effect on implementation of EID program in the health facilities. Implementation of EID program was ineffective in both rural and urban PHCs of Akwa Ibom state with the p-value of 0.337. In multiple regression analysis, access to EID program and provision of adequate supplies significantly affected implementation of the program with p = 0.001 and p = 0.000 respectively. Conclusion and Implication for Translation: The study indicates general ineffectiveness in the implementation of EID in a Southern State of Nigeria. There is need to improve access to EID services and provide needed supplies if the state, and by extension Nigeria, hopes to meet the target of joining the global community in ending HIV by 2030.

Associations of Sociodemographic and Clinical Factors with Late Presentation for Early Infant HIV Diagnosis (EID) Services in Kenya.

Background:Understanding the missed opportunities in early infant HIV testing within the PMTCT program is essential to address any gaps. The study set out to describe the clinical and sociodemographic characteristics of the infants presenting late for early infant diagnosis in Kenya.Methods:We abstracted routinely collected clinical and sociodemographic characteristics, in a cross-sectional study, on all HIV-infected infants with a positive polymerase chain reaction (PCR) test from 1,346 President’s Emergency Plan for AIDS Relief (PEPFAR) supported health facilities for the period October 2016 to September 2018. We used multivariate logistic regression to examine the association of sociodemographic and clinical characteristics with late (>2 months after birth) presentation for infant HIV testing.Results:Of the 4,011 HIV-infected infants identified, the median infant age at HIV diagnosis was 3 months [interquartile range (IQR), 1-16 months], and two-thirds [2,669 (66.5%)] presented late for infant HIV testing. Factors that were associated with late presentation for infant testing were: maternal ANC non-attendance, adjusted odds ratio (aOR) 1.41 (95% confidence interval (CI) 1.18 -1.69); new maternal HIV diagnosis, aOR 1.45, (95%CI 1.24 -1.7); and lack of maternal antiretroviral therapy(ART), aOR 1.94, (95% CI 1.64 - 2.30). There was a high likelihood of identifying HIV-infected infants among infants who presented for medical services in the outpatient setting (aOR 18.9; 95% CI 10.2 - 34.9) and inpatient setting (aOR 12.2; 95% CI 6.23-23.9) compared to the infants who presented late in maternity.Conclusion and Global Health Implications:Gaps in early infant HIV testing suggest the need to increase maternal pre-pregnancy HIV diagnosis, timely antenatal care, early infant diagnosis services, early identification of mothers who seroconvert during pregnancy or breastfeeding and improved HIV screening in outpatient and inpatient settings. Early referral from the community and access to health facilities should be strengthened by the implementation of national PMTCT guidelines.

Factors Influencing Loss to Follow-up among Human Immunodeficiency Virus Exposed Infants in the Early Infant Diagnosis Program in Phalombe, Malawi

The efforts to prevent mother to child transmission of HIV in Malawi are impeded by the loss to follow-up of HIV-exposed infants (HEI) in care. Early infant diagnosis (EID) of HEI and linkage to care reduces morbidity and mortality. There has been limited attention to infants who are lost to follow up despite their mothers being compliant to the PMTCT program. This study explored factors that influence loss-to-follow up among HEI in the EID program whose mothers were retained in care for up to 24 months in Phalombe district, Malawi. We conducted a descriptive phenomenological qualitative study from May 2017 to July 2018. We purposively conducted 18 in-depth interviews among HIV positive mothers whose HEI were enrolled in the follow-up program and 7 key informant interviews among healthcare workers (HCW). All interviews were digitally recorded, transcribed, and translated verbatim. Data were analyzed manually using a thematic step-by-step approach. Results showed that retention in care is facilitated by aspirations to have a healthy infant and linkage to a nearer facility to a mother’s place of residency. The barriers to retention were non-disclosure of HIV status, inadequate resources, and support, suboptimal guidelines for, a lack of privacy, and unsynchronized hospital visits between a mother and her baby. The study has shown that successful implementation of EID services requires concerted efforts from various contextualized stakeholders whilst focusing on family-centered care. To maximize retention in EID and innovative ways of reaching mothers and babies through flexible guidelines are urgently needed.

Mother-child separation among women living with HIV and their children in the first four years postpartum in South Africa.

Mother-child pairs may separate during early life, yet the health impacts thereof are unclear. We explored the patterns and impact of separation among women living with HIV (WLHIV) and their children in South Africa. WLHIV who had initiated antiretroviral therapy (ART) during pregnancy received HIV viral load (VL) testing and completed a timeline questionnaire of mother-child separation since delivery at 3-5years post-partum. Health care usage was abstracted from routine medical records. We examined associations between separation and (a) maternal health outcomes (engagement in HIV care and HIV viral suppression, [VS]) and (b) child health outcomes (post-breastfeeding HIV testing and immunisation completion), using logistic regression. Of 346 mother-child pairs (median maternal age at antenatal ART initiation, 28years), 24% were ever separated (median time to first separation 20months, interquartile range [IQR] 9, 31). Most separated children were living with their grandmothers (65/83, 78%). Mothers who ever separated were younger, and more likely to be employed, and to reside in informal housing than those who never separated. Any separation reduced the odds of VS≤50 copies/mL at four years post-partum (odds ratio 0.57; 95% CI 0.34-0.93); associations were similar for VL≤1000 copies/mL and maternal engagement in care. No association was found between separation and child confirmatory HIV testing or immunisation completion. In this setting, mother-child separation is common in the first four years of life and appears associated with suboptimal maternal outcomes. Further research is required to understand the drivers and implications of mother-child separation.

Implementation planning for community-based point-of-care HIV testing for infants: Recommendations from community leaders in Kenya.

BackgroundEarly infant diagnosis (EID) establishes the presence of HIV infection in HIV-exposed infants and children younger than 18 months of age. EID services are hospital-based, and thus fail to capture HIV-exposed infants who are not brought to the hospital for care. Point-of-care (POC) diagnostic systems deployed in the community could increase the proportion tested and linked to treatment, but little feasibility and acceptability data is available.MethodsSemi-structured interviews (n = 74) were conducted by a Kenyan team with community members (Community Health Workers/Volunteers [CHW/CHV], Traditional Birth Attendants [TBAs], community leaders) and parents of HIV-exposed infants at four study sites in Kenya to elicit feedback on the acceptability and feasibility of community-based POC HIV testing.ResultsParticipants described existing community health resources that could be leveraged to support integration of community-based POC HIV testing; however, the added demand placed on CHW/CHV could pose a challenge. Participants indicated that other potential barriers (concerns about confidentiality, disclosure, and HIV stigma) could be overcome with strong engagement from trusted community leaders and health providers, community sensitization, and strategic location and timing of testing. These steps were seen to improve acceptability and maximize the recognized benefits (rapid results, improved reach) of community-based testing.ConclusionCommunity members felt that with strategic planning and engagement, community-based POC HIV testing could be a feasible and acceptable strategy to overcome the existing barriers of hospital-based EID.

Characteristics of HIV/ Malaria co-infected mothers who did not access early infant diagnosis for their HIV-exposed infants in Benin-City, Nigeria

Background: Perinatally-acquired HIV infections rapidly lead to death within one to two years of life. Early infant diagnosis (EID) is the key to early identification with the prompt commencement of treatment. This has been shown to reduce morbidity and mortality. In Nigeria, only 21% of HIV-infected infants are on ARTs. Objective: To determine the characteristics of HIV/Malaria co-infected mothers who did not access EID for their HIV- exposed infants. Methods: HIV infected mothers were recruited from three hospitals during the last trimester of pregnancy and were tested for peripheral and placental malaria at delivery. Socio-demographic and some clinical characteristics were obtained using a proforma. Following delivery, the babies were commenced on the Prevention of Mother to Child Transmission (PMTCT) protocol for HIV including prophylactic Nevirapine therapy, infant feeding counselling and performance of DNA PCR at 6-8 weeks of life. Mothers whose infants did not have DNA PCR results were categorized as having not accessed EID services. Results: Of the 162 infants, only 101 (62.4%) had a DNA PCR test done. The mean age of mothers who did not access EID (31.84±4.8 years) was significantly higher than for mothers who accessed EID (30.58±3.09 years) (p&lt;0.0001). Mothers with low levels of education (p = 0.006), cohabiting mothers (p = 0.0067) and HIV serodiscordant couples (p = 0.0029) were more likely not to access EID. Conclusion: Education, marital status and HIV serodiscordance are significant determinants of accessing EID services. Assessment of these factors at first contact with a pregnant HIV-infected woman allows risk categorisation for default from EID.

Acceptability of Routine Point-of-Care Early Infant Diagnosis in Eight African Countries: Findings From a Qualitative Assessment of Clinical and Laboratory Personnel.

The Elizabeth Glaser Pediatric AIDS Foundation introduced point-of-care (POC) testing for early infant diagnosis (EID) of HIV in 8 African countries. Understanding experiences and opinions of users can help facilitate introduction and sustainability. Cameroon, Côte d'Ivoire, Eswatini, Kenya, Lesotho, Mozambique, Rwanda, and Zimbabwe. Structured interviews with health care workers (HCWs) providing EID services and semistructured interviews with national and regional laboratory managers or EID program managers were conducted before and after the implementation of POC EID. Survey responses were analyzed and compared; open-ended responses were analyzed by theme. In total, 234 and 175 interviews with HCWs and 28 and 14 interviews with laboratory or program managers were conducted before and after the introduction of POC EID, respectively. In preintervention interviews, challenges identified with laboratory-based EID testing included distance from patients' residence to the health facility, time-consuming sample transportation to central laboratories, stockout of testing kits, and long wait times for results. Postintervention data revealed that HCWs found POC EID easy to use and were very satisfied with the fast turnaround time and ability to initiate treatment for HIV-infected infants sooner. Laboratory managers were also supportive of scaling-up POC testing although cautious of the need for reliable infrastructure to operate platforms. The recommendation was that POC EID be integrated within the national diagnostic testing network. Support for POC EID from key stakeholders is essential for sustainability. Overall, participants supported the rollout of POC testing for EID, noting challenges and opportunities for scaling-up POC EID and recommending integration into the overall EID system.

Barriers to early infant diagnosis of HIV in the Wa Municipality and Lawra District of Upper West Region, Ghana

We identified socio-demographic, health system and psycho-social barriers to Early Infant Diagnosis (EID) of HIV in the Upper West Region of Ghana. An unmatched case control study of 96 cases and 96 controls was conducted in the ART centers in Lawra district and Wa Municipality between December 2014 and April 2015. A public health facility. We defined a case as an HIV positive mother with an exposed infant who received EID service between January 2011 and December 2014. A control was defined as HIV Positive Mother with an exposed infant who did not receive EID services between January 2011 and December 2014. EID by dry blood spot Deoxyribonucleic acid Polymerase chain reaction. A total of 192 mother-infant pairs were assessed. The mean age of infants at testing for cases was 17.3±14.9 weeks. Mother-to-child-transmission-rate was 2.3%. Factors associated with EID testing included: mother being formally employed (cOR=2.0: 95%CI:1.1-3.8), maternal formal education (cOR=2.0, 95%CI: 1.1-3.6) and maternal independent source of income (cOR 2.2, 95%CI 1.2-4.1). After adjusting for confounders, maternal independent income source was associated with EID testing (aOR 2.2, 95%CI 1.2-4.1). Median turn-around time of EID result was 11 weeks (IQR 4-27 weeks). Women need to be empowered to gain an independent source of income. This can help maximize the benefits of e-MTCT and increase EID in the Upper West Region of Ghana.

Predictors of Early ART Initiation Among HIV + Infants in Kenya: A Retrospective Review of HITSystem Data from 2013 to 2017.

Early initiation of antiretroviral therapy (ART, before 12weeks of age) among infants living with HIV reduces infant mortality and slows disease progression. However, inefficiencies in early infant diagnosis processes prevents timely ART initiation among infants living with HIV in Kenya. This study assesses predictors of early ART initiation among infants living with HIV in Kenya. We retrospectively reviewed data from 96 infants living with HIV born between January 2013 and June 2017 at 6 Kenyan government hospitals. The primary outcome was infant receipt of ART by 12weeks of age. We assessed bivariable and multivariable predictors of ART initiation by 12weeks of age. Among 96 infants living with HIV, 82 (85.4%) infants initiated ART at a median infant age of 17.1weeks. Of the 82 infants who started ART, only 17 (20.7%) initiated ART by 12weeks of age. In multivariable logistic regression analyses, testing per national guidelines (< 7weeks of age) (aOR 40.14 [3.96-406.97], p = 0.002), shorter turnaround time for result notification (≤ 4weeks) (aOR 11.30 [2.02-63.34], p = 0.006), and ART initiation within 3days of mother notification (aOR 7.32 [1.41-38.03], p = 0.006) were significantly associated with ART initiation by 12weeks of age. Current implementation of early infant diagnosis services in Kenyan only achieves targets for early ART initiation in one-fifth of infants with HIV. Strengthening services to support earlier infant testing and streamlined processes for early infant diagnosis may increase the proportion of infants who receive timely ART.
