Factors influencing the delivery and uptake of early infant diagnosis of HIV services in Greater Accra, Ghana: A qualitative study

Building a Healthier Future: A Narrative Review on Early Infant Diagnosis's Role in HIV Prevention

Background and Aims

Early infant diagnosis (EID) is a critical intervention in the global fight against pediatric HIV, providing early identification and treatment for HIV-exposed infants. This narrative review examines the role of EID in reducing vertical transmission, improving health outcomes, and mitigating stigma in communities. The review also explores innovations, challenges, and strategies for optimizing EID programs.

Methods

A comprehensive literature search was conducted across databases such as PubMed, Scopus, and WHO reports to identify relevant studies, guidelines, and program evaluations. Key focus areas included diagnostic techniques, implementation strategies, and community impacts of EID programs, with an emphasis on their integration into broader HIV care frameworks.

Results

EID enables the early detection of HIV in infants, allowing timely initiation of antiretroviral therapy (ART), which reduces morbidity and mortality. It also indirectly prevents postnatal transmission during breastfeeding by lowering viral loads in treated infants. Innovations such as point-of-care testing and digital health tools have improved access and efficiency, particularly in resource-limited settings. EID programs have demonstrated a positive societal impact by raising awareness, reducing stigma, and fostering trust in healthcare systems. However, significant challenges persist, including logistical barriers, infrastructure limitations, and socioeconomic constraints that hinder program effectiveness.

Conclusion

EID is essential for addressing pediatric HIV, contributing to the elimination of vertical transmission and improving outcomes for HIV-exposed infants. To enhance its impact, stakeholders must prioritize expanding access to diagnostic tools, strengthening healthcare infrastructure, and engaging communities through education and advocacy. EID programs not only save lives but also foster societal shifts towards inclusivity and acceptance, paving the way for a healthier, HIV-free future.

Uptake of early infant HIV diagnosis and its associated factors in Tanzania: an analytical cross-sectional study

The uptake of early infant HIV diagnosis services is crucial for preventing mother to child transmission of virus, and timely management. However, the uptake of the services remains a global challenge, despite major advances in HIV testing. This study investigated the uptake of early infant HIV diagnosis and its associated factors among mothersof exposed infants. The results showed that the uptake of early infant HIV diagnosis was 76%. Factors associated with the uptake are caregivers being married, have higher income level and having adequate knowledge on early infant HIV diagnosis.

Sustainable solutions to barriers of point-of-care diagnostic testing services in health facilities without laboratories in the bono region, Ghana: a qualitative study

BACKGROUND

A sustainable point-of-care (POC) diagnostic testing implementation in low-resourced facilities enhances quick diagnostic investigation and halts unnecessary referrals. This study identified the barriers impeding the implementation of POC diagnostic testing in health facilities without laboratories in the Bono Region of Ghana; as well as explored potential solutions that could enhance the accessibility and effectiveness of POC diagnostic testing, ultimately improving the quality of healthcare delivery.

METHODS

A total of twenty-eight participants were purposively selected from health facilities in low-resourced settings in the Bono Region for a descriptive qualitative study. Of the twenty-eight participants, seventeen including ten healthcare providers from CHPS facilities, six district health depot managers, and one regional depot manager were engaged in in-depth interviews. Additional eleven including nine healthcare providers and two district depot managers were also engaged in focus group discussions. NVivo version 12 software was employed for condensation, labelling, and grouping of themes. Data was analysed narratively.

RESULTS

Work overloads, limited POC testing services, stock-outs of POC tests at the facilities, and supply-related challenges of POC test kits were identified as major barriers to POC testing services. To solve these barriers, adequate funding, an effective delivery system, stakeholders' engagement and advocacy, and in-service and refresher training courses were suggested as potential solutions to POC diagnostic testing services implementation by the stakeholders.

CONCLUSIONS

This study's findings emphasize the need to address the barriers hindering the implementation of POC diagnostic testing in health facilities without laboratories in the Bono Region of Ghana. The suggested solutions provide a roadmap for improving the accessibility and effectiveness of POC testing, which has the potential to enhance the quality of healthcare delivery, reduce unnecessary referrals, and ultimately improve patient health outcomes in underserved settings.

Xpert HIV-1 qual point-of-care testing for HIV early infant diagnosis in Tanzania: experiences and perceptions of health care workers in a 2016 study

BACKGROUND

HIV early infant diagnosis (HEID) at the centralized laboratory faces many challenges that impact the cascade of timely HEID. Point of Care (PoC) HEID has shown to reduce test turnaround times, allow for task shifting and has the potential to reduce infant mortality. We aimed at assessing the feasibility of nurse based PoC-HEID in five facilities of Mbeya region.

METHODS

We analysed data from healthcare workers at five obstetric health facilities that participated in the BABY study which enrolled mothers living with HIV and their HIV exposed infants who were followed up until 6 weeks post-delivery. Nurses and laboratory personnel were trained and performed HEID procedures using the Xpert HIV-1 Qual PoC systems. Involved personnel were interviewed on feasibility, knowledge and competency of procedures and overall impression of the use of HIV-1 Qual PoC system in clinical settings.

RESULTS

A total of 28 health care workers (HCWs) who participated in the study between 2014 and 2016 were interviewed, 23 being nurses, 1 clinical officer, 1 lab scientist and 3 lab technicians The median age was 39.5 years. Majority of the nurses (22/24) and all lab staff were confident using Gene Xpert PoC test after being trained. None of them rated Gene Xpert handling as too complicated despite minor challenges. Five HCWs (5/24) reported power cut as the most often occurring problem. As an overall impression, all interviewees agreed on PoC HEID to be used in clinical settings however, about half of them (11/24) indicated that the PoC-HEID procedures add a burden onto their routine workload.

CONCLUSION

Overall, health care workers in our study demonstrated very good perceptions and experiences of using PoC HEID. Efforts should be invested on quality training, targeted task distribution at the clinics, continual supportive supervision and power back up mechanisms to make the wide-scale adoption of nurse based PoC HEID testing a possibility.

Understanding the uptake and determinants of prevention of mother-to-child transmission of HIV services in East Africa: Mixed methods systematic review and meta-analysis

BACKGROUND

Prevention of mother-to-child transmission (PMTCT) of HIV service is conceptualized as a series of cascades that begins with all pregnant women and ends with the detection of a final HIV status in HIV-exposed infants (HEIs). A low rate of cascade completion by mothers' results in an increased risk of HIV transmission to their infants. Therefore, this review aimed to understand the uptake and determinants of key PMTCT services cascades in East Africa.

METHODS

We searched CINAHL, EMBASE, MEDLINE, Scopus, and AIM databases using a predetermined search strategy to identify studies published from January 2012 through to March 2022 on the uptake and determinants of PMTCT of HIV services. The quality of the included studies was assessed using the Mixed Methods Appraisal Tool. A random-effects model was used to obtain pooled estimates of (i) maternal HIV testing (ii) maternal ART initiation, (iii) infant ARV prophylaxis and (iv) early infant diagnosis (EID). Factors from quantitative studies were reviewed using a coding template based on the domains of the Andersen model (i.e., environmental, predisposing, enabling and need factors) and qualitative studies were reviewed using a thematic synthesis approach.

RESULTS

The searches yielded 2231 articles and we systematically reduced to 52 included studies. Forty quantitative, eight qualitative, and four mixed methods papers were located containing evidence on the uptake and determinants of PMTCT services. The pooled proportions of maternal HIV test and ART uptake in East Africa were 82.6% (95% CI: 75.6-88.0%) and 88.3% (95% CI: 78.5-93.9%). Similarly, the pooled estimates of infant ARV prophylaxis and EID uptake were 84.9% (95% CI: 80.7-88.3%) and 68.7% (95% CI: 57.6-78.0) respectively. Key factors identified were the place of residence, stigma, the age of women, the educational status of both parents, marital status, socioeconomic status, Knowledge about HIV/PMTCT, access to healthcare facilities, attitudes/perceived benefits towards PMTCT services, prior use of maternal and child health (MCH) services, and healthcare-related factors like resource scarcity and insufficient follow-up supervision.

CONCLUSION

Most of the identified factors were modifiable and should be considered when formulating policies and planning interventions. Hence, promoting women's education and economic empowerment, strengthening staff supervision, improving access to and integration with MCH services, and actively involving the community to reduce stigma are suggested. Engaging community health workers and expert mothers can also help to share the workload of healthcare providers because of the human resource shortage.

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

BACKGROUND

India 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.

METHODS

The 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.

RESULTS

The 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.

DISCUSSION

The 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.

CONCLUSION

The study findings have high significance for developing program implementation strategies to improve access and to build right-based and patient-centred EID services.

A scoping review on HIV early infant diagnosis among HIV exposed infants, ART use and adherence in Tanzania

BACKGROUND

HIV Early Infant Diagnosis (HEID) is critical for the timely initiation of HIV treatments and improved health outcomes among HIV-infected infants. However, the uptake of HEID remains largely low in Tanzania. This descriptive scoping review of evidence on HEID among HIV-exposed infants in Tanzania seeks to understand the dynamics of HEID, ART use and adherence to inform targeted interventions and promote its uptake.

METHODS

The Arksey and O'Malley's methodological framework guided this scoping review. We searched for peer-published articles on HEID in Tanzania through PubMed and Google Scholar with full-text retrieval from HINAR. We included only English language articles published between 2013 and 2022. Further searches for the materials on the reference lists of the publications yielded additional relevant articles. We carried out an inductive thematic analysis to analyze and synthesize the data.

RESULTS

In all, nine articles met the inclusion criteria and, hence, qualified for the review. The variations in the uptake of HEID in the empirical literature reviewed indicate an upward trend. HEID increased from 77.2% in 2009 to 97.8% in 2011 in Kilimanjaro, Mbeya and Tanga and from 53.2% in 2014 to 69.2% in 2016 in Dar es Salaam. The median age at the initial test ranged from 5.6 weeks in Kilimanjaro to 8.6 weeks in Mbeya. The uptake of HEID was necessitated by individual, household and health facility factors. Unknown HIV status at conception, low level of education of the household head, and large household size negatively affected uptake of HEID. The health facility factors such as unavailability of the test kits, long distances to the facility and transport costs negatively influenced HEID uptake. The percentage of HIV-positive infants on ART ranged from 52.7 to 61%, and loss to follow ranged from 31 to 61%.

CONCLUSION

The uptake of HEID varied among regions depending on individual, household and health facility factors. Multifaced efforts are needed to address these factors for accelerated uptake of HEID and improved health outcomes and survival among this strategic population group.

Understanding the uptake of HIV testing among women in Liberia: the role of female genital mutilation/cutting

Past studies show that the processes of female genital mutilation/cutting (FGM/C) on women can increase their susceptibility to HIV infection. This is because genital tears or ruptures, scars and wounds from FGM/C may expose survivors to heightened risks of contracting sexually transmitted infections, including HIV, if they engage in unsafe sexual practices. Hence, there is the need to promote HIV screening and testing among this population. Yet, in Liberia, there is a dearth of studies exploring the uptake of HIV testing among women who have experienced FGM/C. To understand this relationship, we used the 2019-2020 Liberia Demographic and Health Survey (LDHS) and employed logistic regression analysis to answer the following questions: (1) Are FGM/C survivors less likely to have been tested for HIV compared to non-FGM/C women; and (2) How does this disparity in the uptake of HIV testing differ by women's marital status? We found that survivors of FGM/C were less likely to have been tested for HIV than non-FGM/C women, even after accounting for theoretically relevant variables (OR = 0.83, p < 0.01). In response to our second question, we found that survivors of FGM/C who were formerly married were less likely to have been tested for HIV compared to their non-FGM/C counterparts (OR = 0.48, p < 0.01). These findings highlight the importance of trauma-informed HIV prevention strategies in Liberia, and the need for policymakers to take a holistic approach to addressing the challenges that FGM/C survivors, especially formerly married women, may face in accessing HIV prevention and testing services, and to work towards creating a more inclusive and supportive environment for all at-risk groups.

Availability, stock levels and usage of In-vitro diagnostics in the Bono region, Ghana: A cross-sectional study

BACKGROUND

Point-of-care (POC) diagnostic tests play essential roles in diagnosis, surveillance, and disease management in health settings. Nevertheless, implementation challenges may hamper POC test accessibility. This study evaluated the availability and stock levels of the World Health Organization (WHO) prequalified existing in-vitro diagnostics (IVDs) for use in health facilities without laboratories.

AIM

To evaluate the availability, stock levels, and usage of POC diagnostic tests.

SETTING

Bono Region, Ghana.

METHODS

This cross-sectional survey involved 102 randomly selected Community Health-based and Planning Services (CHPS), 12 district health depots, and a regional medical depot. Using a survey tool, data were collected on clinic staffing, availability and stock levels of tests, and funding sources. STATA 17 was employed for data analysis.

RESULTS

Majority (37.3%) of the respondents were community health nurses, with 4.4 mean years of work experience and 38 working hours per week. Of the 18 existing WHO prequalified POC tests for use at facilities without laboratories, 10 (56%), 2 (11%) and 0 (0%) were found at CHPS, regional, and district depots, respectively. Majority (183 out of 301) stock levels were low. Of the 10 available tests found, 7 scored 111 (36%) of 'high use'. Supply chain management compliance was 5 (31%) out of 16. All CHPS received government funding with 25.5% of them receiving additional donor or internally generated funding.

CONCLUSION

This study found poor supply chain management compliance, and low availability of POC tests in the Bono Region of Ghana.Contribution: The study outlines POC tests availability and usage in low-resourced setting.

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

INTRODUCTION

Nigeria 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.

METHODS

This 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).

RESULTS

Twenty-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.

CONCLUSIONS

There 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.

Association between service readiness and PMTCT cascade effectiveness: a 2018 cross-sectional analysis from Manica province, Mozambique

BACKGROUND

Despite high coverage of maternal and child  health services in Mozambique, prevention of mother-to-child transmission of HIV (PMTCT) cascade outcomes remain sub-optimal. Delivery effectiveness is modified by health system preparedness. Identifying modifiable factors that impact quality of care and service uptake can inform strategies to improve the effectiveness of PMTCT programs. We estimated associations between facility-level modifiable health system readiness measures and three PMTCT outcomes: Early infant diagnosis (polymerase chain reaction (PCR) before 8 weeks of life), PCR ever (before or after 8 weeks), and positive PCR test result.

METHODS

A 2018 cross-sectional, facility-level survey was conducted in a sample of 36 health facilities covering all 12 districts in Manica province, central Mozambique, as part of a baseline assessment for the SAIA-SCALE trial (NCT03425136). Data on HIV testing outcomes among 3,427 exposed infants were abstracted from at-risk child service registries. Nine health system readiness measures were included in the analysis. Logistic regressions were used to estimate associations between readiness measures and pediatric HIV testing outcomes. Odds ratios (OR) and 95% confidence intervals (95%CI) are reported.

RESULTS

Forty-eight percent of HIV-exposed infants had a PCR test within 8 weeks of life, 69% had a PCR test ever, and 6% tested positive. Staffing levels, glove stockouts, and distance to the reference laboratory were positively associated with early PCR (OR = 1.02 [95%CI: 1.01-1.02], OR = 1.73 [95%CI: 1.24-2.40] and OR = 1.01 [95%CI: 1.00-1.01], respectively) and ever PCR (OR = 1.02 [95%CI: 1.01-1.02], OR = 1.80 [95%CI: 1.26-2.58] and OR = 1.01 [95%CI: 1.00-1.01], respectively). Catchment area size and multiple NGOs supporting PMTCT services were associated with early PCR testing OR = 1.02 [95%CI: 1.01-1.03] and OR = 0.54 [95%CI: 0.30-0.97], respectively). Facility type, stockout of prophylactic antiretrovirals, the presence of quality improvement programs and mothers' support groups in the health facility were not associated with PCR testing. No significant associations with positive HIV diagnosis were found.

CONCLUSION

Salient modifiable factors associated with HIV testing for exposed infants include staffing levels, NGO support, stockout of essential commodities and accessibility of reference laboratories. Our study provides insights into modifiable factors that could be targeted to improve PMTCT performance, particularly at small and rural facilities.
