Summary: Background: Early-onset Group B Streptococcus (EOGBS) infection leads to substantial morbidity and mortality in newborn infants. Intrapartum antibiotic prophylaxis (IAP) prevents EOGBS infection, but IAP strategies vary. The approach to the provision of IAP can be risk-based, universal or a combination of the two strategies. Previous systematic reviews reported that universal strategies might be most optimal in lowering EOGBS infection, but there is no consensus. Therefore, we aimed to provide up-to-date evidence on effectiveness of different strategies by comparing perinatal outcomes. Methods: A systematic search for EOGBS prevention strategies was performed in MEDLINE, Embase and Web of Science on May 2024. Studies were included if they reported on different strategies and outcomes of interest, including EOGBS infection, IAP administration and antimicrobial resistance regardless of publication date. Summary data was extracted from published reports. Study quality was assessed using the ROBINS-I tool. Random-effects meta-analyses were used to determine risk ratios (RR) and 95%-confidence intervals. PROSPERO registration CRD42023411806. Findings: A total of 6293 records were identified, of which 72 observational studies were included for synthesis with more than 10 million live births. Meta-analysis demonstrated that implementation of any strategy (n = 34 studies, RR 0.46 (0.36–0.60)), risk-based strategies (n = 11 studies, RR 0.65 (0.48–0.87)), or universal strategies (n = 16 studies, RR 0.37 (0.25–0.55)) was associated with a reduced risk of EOGBS infection compared to no strategy. In direct comparison, universal strategies were associated with a reduced risk of EOGBS compared to a risk-based strategy (n = 17 studies, RR 0.41 (0.30–0.55)), while the proportion of women receiving IAP did not differ between risk-based (16%) and universal (21%) strategies (n = 9 studies, RR 1.29 (0.95–1.75)). There was no antimicrobial resistance of EOGBS isolates to penicillin or ampicillin (n = 11 studies). Interpretation: Any IAP strategy could reduce the risk of EOGBS infection without evidence of increasing antimicrobial resistance. Universal strategies give the largest reduction in the EOGBS burden, while not exposing a significantly higher proportion of pregnancies to IAP compared to risk-based strategies. Funding: UNDP-UNFPA-UNICEF-WHO-World Bank Special Programme of Research, Development and Research Training in Human Reproduction, a cosponsored programme executed by the World Health Organization.

Abstract Introduction The COVID-19 pandemic has globally impacted health service access, delivery and resources. There are limited data regarding the impact on the prevention of mother to child transmission (PMTCT) service delivery in low-resource settings. Neotree ( www.neotree.org ) combines data collection, clinical decision support and education to improve care for neonates. Here we evaluate impacts of COVID-19 on care for HIV-exposed neonates. Methods Data on HIV-exposed neonates admitted to the neonatal unit (NNU) at Sally Mugabe Central Hospital, Zimbabwe, between 01/06/2019 and 31/12/2021 were analysed, with pandemic start defined as 21/03/2020 and periods of industrial action (doctors (September 2019-January 2020) and nurses (June 2020-September 2020)) included, resulting in modelling during six time periods: pre-doctors’ strike (baseline); doctors’ strike; post-doctors’ strike and pre-COVID; COVID and pre-nurses’ strike; nurses’ strike; post nurses’ strike. Interrupted time series models were used to explore changes in indicators over time. Results Of 8,333 neonates admitted to the NNU, 904 (11%) were HIV-exposed. Mothers of 706/765 (92%) HIV-exposed neonates reported receipt of antiretroviral therapy (ART) during pregnancy. Compared to the baseline period when average admissions were 78 per week (95% confidence interval (CI) 70–87), significantly fewer neonates were admitted during all subsequent periods until after the nurses’ strike, with the lowest average number during the nurses’ strike (28, 95% CI 23–34, p 0.22) in numbers of admissions or mortality by HIV exposure status. Fewer HIV-exposed neonates received a PCR test during the pandemic (23%) compared to the pre-pandemic periods (40%) (RR 0.59, 95% CI 0.41–0.84, p

ABSTRACT: Objectives: Point-of-care (POC) devices for infant HIV testing provide timely result-return and increase antiretroviral (ART) initiation. We aimed to optimally locate POC devices to increase 30-day ART initiation in Matabeleland South, Zimbabwe. Methods: We developed an optimization model to identify the locations for limited POC devices at health facilities, maximizing the number of infants who receive HIV test results and initiate ART within 30 days of testing. We compared location-optimization model results to non-model-based decision heuristics, which are more practical and less data-intensive. Heuristics assign POC devices based on demand, test positivity, laboratory result-return probability, and POC machine functionality. Results: With the current placement of 11 existing POC machines, 37% of all tested infants with HIV were projected to receive results and 35% were projected to initiate ART within 30 days of testing. With optimal placement of existing machines, 46% were projected to receive results and 44% to initiate ART within 30 days, retaining three machines in current locations, moving eight to new facilities. Relocation based on the highest POC device functionality would be the best-performing heuristic decision (44% receiving results and 42% initiating ART withing 30 days); although, it still would not perform as well as the optimization-based approach. Conclusion: Optimal and ad hoc heuristic relocation of limited POC machines would increase timely result-return and ART initiation, without further, often costly, interventions. Location optimization can enhance decision-making regarding the placement of medical technologies for HIV care.

Background: Perioperative nursing plays an important role in the success of any surgery. In Malawi, pre-service training is the only source of perioperative knowledge for nurses. In order to ensure that nurses are adequately prepared with perioperative knowledge and skills, an effective assessment of perioperative competence is required. The Perceived Perioperative Competence Scale-Revised (PPCS-R) is a scientifically developed and psychometrically validated tool for assessing perioperative nurses’ competence. Therefore, this study aimed to adapt and evaluate the psychometric properties of the Perioperative Competence Scale-Revised (PPCS-R) for use on undergraduate student nurses in Malawi. Methods: The adaptation of the PPCS-R involved a review by a panel of experts for content validity followed by an evaluation of Psychometric properties through a confirmatory factor analysis. The confirmatory factor analysis evaluated the reliability coefficient and factor loading for the scale based on data from 100 former nursing students. Results: Content analysis led to the exclusion of six items while twelve items were revised. The confirmatory Factor Analysis yielded 6 factors with Cronbach’s alpha ranging between 0.811 to 0.879. Conclusion: The Malawian student version of the PPCS-R has good reliability, validity, and psychometric properties. This will enable nurse educators, preceptors, clinical nurses, and even student nurses to assess perioperative nursing competency for undergraduate student nurses in Malawi.

Medicine ,Science - Abstract
Early adolescence is a period characterized by enormous biological, cognitive, sexual, emotional, and social changes. Sexual curiosity and the desire to acquire sexual health (SH) information are part of these developments. Understanding the SH knowledge acquisition process is critical for designing interventions that can best support very young adolescents (VYAs). This study explored the SH knowledge acquisition processes among VYA girls aged 10 to 14 years who attended the DREAMs Girl Only Clubs (GOCs) and those who did not. The GOCs were a part of a larger comprehensive HIV prevention project called DREAMS (Determined, Resilient, Empowered, AIDS-free, Mentored, and Safe) which provided an evidence-based core package of interventions to VYAs to prevent HIV. In-depth interviews were conducted with 43 VYA girls aged 10-14 years in two rural southern districts of Zomba and Machinga in Malawi. Twenty-three VYA girls were GOC participants and 20 VYAs were not. Guided by the Social Ecological Model, a thematic analysis approach was used to analyze the data with the assistance of Nvivo 12 software. The SH knowledge acquisition processes were the interaction of various factors at the microsystem (self-efficacy, attitudes, trust and the beginning of menstruation), mesosystem (communication of SH issues between VYAs and their immediate family and peers), and exosystem levels (availability of life skills programs and mother-groups in schools and availability of GOCs). Compared to Non-GOC participants, GOC participants demonstrated an in-depth knowledge of SH issues and positive sexual behaviors such as HIV testing. Limitations to SH knowledge acquisition were adult messages' focus on sexual relationship avoidance and on girls who have started menstruation; the perception of adults not being knowledgeable about SH and school teachers hiding some SH information. VYAs' SH interventions that provide VYAs with accurate, consistent, and age-appropriate SH information such as the GOCs have the potential to address the limitations that other sources have in reaching VYAs. Integrating such interventions with programs that empower parents, other adults, and teachers with comprehensive SH information and with skills on how to deliver SH information to VYAs can enhance VYAs' SH knowledge acquisition and influence positive behavior change.

The COVID-19 pandemic and associated measures may have disrupted delivery of maternal and neonatal health services and reversed the progress made towards dual elimination of mother-to-child transmission of HIV and syphilis in Zimbabwe. This qualitative study explores the impact of the pandemic on the provision and uptake of prevention of mother-to-child transmission (PMTCT) services from the perspectives of women and maternal healthcare providers. Longitudinal in-depth interviews were conducted with 20 pregnant and breastfeeding women aged 20-39 years living with HIV and 20 healthcare workers in two maternity polyclinics in low-income suburbs of Harare, Zimbabwe. Semi-structured interviews were held after the second and third waves of COVID-19 in March and November 2021, respectively. Data were analysed using a modified grounded theory approach. While eight antenatal care contacts are recommended by Zimbabwe's Ministry of Health and Child Care, women reported only being able to access two contacts. Although HIV testing, antiretroviral therapy (ART) refills and syphilis screening services were accessible at first contact, other services such as HIV-viral load monitoring and enhanced adherence counselling were not available for those on ART. Closure of clinics and shortened operating hours during the second COVID-19 wave resulted in more antenatal bookings occurring later during pregnancy and more home deliveries. Six of the 20 (33%) interviewed women reported giving birth at home, assisted by untrained traditional midwives as clinics were closed. Babies delivered at home missed ART prophylaxis and HIV testing at birth despite being HIV-exposed. Although women faced multiple challenges, they continued to attempt to access services after delivery. These findings underline the importance of investing in robust health systems that can respond to emergency situations to ensure continuity of essential HIV prevention, treatment, and care services.

- Abstract
Evidence syntheses that engage librarians as co-authors produce higher-quality results than those that do not. Trained as teachers, researchers, and information managers, librarians possess expert knowledge on research methodologies and information retrieval approaches that are critical for evidence synthesis. Researchers are under increasing pressure to produce evidence syntheses to inform practice and policymaking. Many fields outside of health science and medicine, however, do not have established guidelines, processes, or methodologies. This article describes how librarians led the creation of an interdisciplinary toolkit for researchers new to evidence synthesis. The implementation of the tools, including a protocol, supported eight evidence syntheses focused on effective agricultural interventions published in a special collection in Nature Research in October 2020. This article is a step-by-step overview of the tools and process. We advocate that librarian collaboration in evidence synthesis must become the norm, not the exception. Evidence synthesis project leads without access to a qualified librarian may use this toolkit as a point of entry for production of transparent, reproducible reviews.

The production of evidence syntheses, such as systematic and scoping reviews, is vital to supporting evidence-based policy- and decision-making, and to inform work toward achieving the Sustainable Development Goals. The conduct of high-quality evidence synthesis requires specialized knowledge and methods. Many initiatives have been implemented to increase capacity for evidence synthesis production globally, including targeted regional efforts in Africa. The current study uses bibliometric methods to analyze trends in evidence synthesis production by Africa-based authors across disciplines, providing a baseline for future research and evaluation of capacity-building efforts. We find that evidence synthesis production in Africa has grown rapidly in the past ten years, particularly for systematic reviews in the health and medical disciplines. Other evidence synthesis methods, mainly scoping reviews, are also applied and non-health disciplines are increasingly using evidence synthesis methods to assess current knowledge. We also discuss interesting country- and discipline-specific trends.

Public aspects of medicine ,RA1-1270 - Abstract
Zimbabwe is targeting elimination of mother-to-child transmission of HIV by December 2025, however the COVID-19 pandemic challenged health service delivery globally. Monthly aggregated data were extracted from DHIS-2 for all facilities delivering antenatal care (ANC). ZIMSTAT and Spectrum demographic estimates were used for population-level denominators. Programme indicators are among those in HIV care and population indicators reflect the total population. The mean estimated proportion of pregnant women booking for ANC per month did not change (91% pre-pandemic vs 91% during pandemic, p = 0.95), despite dropping to 47% in April 2020. At a programme-level, the estimated proportion of women who received at least one HIV test fell in April 2020 (3.6% relative reduction vs March (95% CI 2.2-5.1), p

Public aspects of medicine ,RA1-1270 - Abstract
Early sexual relationships are associated with an increased risk of acquiring sexually transmitted diseases including HIV/AIDs, teenage pregnancies, and unsafe abortions among other negative health outcomes. Understanding sexual relationships among very young adolescents (VYAs) is important to equip them to protect themselves from negative sexual health (SH) outcomes. DREAMS (Determined, Resilient, Empowered, AIDS-free, Mentored, and Safe) is an HIV prevention initiative that provided an evidence-based core package of interventions to VYAs to prevent HIV acquisition in 15 countries in sub-Saharan Africa. The Girl Only Club (GOC) was the primary context for the interventions. Our objective in this study was to explore if there was any difference in social support (SS) received concerning sexual relationships between the VYA girls who attended GOCs and those who did not. In-depth interviews were conducted with 43 VYA girls, aged 10-14 years, in two rural southern districts, Zomba and Machinga, in Malawi. Twenty-three VYA girls were participants in GOCs and 20 VYA girls did not participate. A thematic, descriptive approach that involved a constant comparative analysis guided the data analysis, and Nvivo 12 software was used. In both study sites available SS concerning sexual relationships is informational support including information from parents, older relatives, and friends. However, club participants differed from non-club participants in sexual and reproductive health (SRH) knowledge and use. Club participants reported consulting others on decision-making and information on sexual relationships; receiving detailed SH information from clubs; condom use due to education received from the clubs; quitting sexual relationships; and correcting misinformation with club information. GOC participants received more SS which made them more knowledgeable and better at handling sexual relationship issues than those not in clubs. Interventions that integrate SS including social asset building and safe spaces are critical for VYA SRH programming.

Plain language summary There is limited data on modern family planning method use of young adolescents aged 10–14 years compared to older adolescents aged 15–19 years. The study assessed factors that influence modern family planning method decision-making and use among young adolescents aged 10–14 years. The Theory of Reasoned Action model was applied to understand the processes that influence modern family planning method decision-making and use among young adolescents. The study was conducted in 6 youth health-friendly services clinics and 12 youth clubs where adolescents access contraceptives. We conducted 2 focus group discussions and 26 in-depth interviews. The study involved sexually active, in and out of school young adolescents and influential decision-makers in reproductive health. The results are presented in a narrative format using themes identified during analysis in line with study objectives. The study discovered that modern family planning method decision-making is influenced by social factors; hormonal side effects of modern family planning methods and improper linkage between Sexual and Reproductive Health Rights and Education policies. The findings suggest the need to empower girls in decision-making. Address myths surrounding modern family planning methods. Then harmonize Sexual and Reproductive Health Rights and Education Policies in the country.

Medicine - Abstract
Introduction Targeting very young adolescents (VYAs) with sexual health (SH) interventions is increasingly being recognised as one of the strategies for addressing SH challenges in late adolescence. However, there is a dearth of literature regarding SH interventions implemented specifically for VYAs in sub-Saharan Africa (SSA). This scoping review aims to provide a summary of documented evidence on SH interventions that include VYAs in SSA, identify gaps in existing interventions and provide recommendations for further programmatic work on SH for VYAs.Methods and analysis The methods for this scoping review will be guided by the framework proposed by Arksey and O’Malley and further enhanced by Levac et al and the Joanna Briggs Institute. We will search electronic databases: Popline, EMBASE, PubMed, CINAHL, Dimensions, African Journals Online (AJOL) and specific summon country-specific search. We will include published studies from SSA and only adolescent SH interventions published from the year 2003–2022. Furthermore, we will include programmatic and intervention literature that has not been published in peer-reviewed articles. The data will be charted using the Preferred Reporting Items for Systematic Review and Meta-Analysis Extension for Scoping Review. The data will then be collated and summarised.Ethics and dissemination The scoping review methodology involves putting together information from articles or grey literature that is either publicly available or shared by the authors, this study does not require ethical approval. Findings of this scoping review will be published in a scientific journal and presented at relevant scientific fora and conferences. This scoping review will provide a comprehensive overview of the evidence base of adolescent SH interventions for VYAs in SSA and will highlight critical gaps in the existing interventions and areas where further programmatic work is needed for VYAs in SSA.Registration https://archive.org/details/osf-registrations-gn538-v1.

Abstract Background In 2013, the World Health Organisation (WHO) recommended Option B+ as a strategy to prevent mother-to-child transmission (PMTCT) of HIV. In option B+ , lifelong antiretroviral therapy (ART) is offered to all HIV positive pregnant and breastfeeding women to reduce MTCT rate to less than or equal to 5%. Its success depends on retaining women on ART during pregnancy, delivery and breast-feeding period. There is limited data on early retention on ART among pregnant women in Zimbabwe. We therefore assessed early retention among women on Option B + from antenatal care (ANC) until 6 months post ANC booking and at delivery in Bulawayo city and Mazowe rural district of Zimbabwe. Methods We collected data for pregnant women booking for ANC between January and March 2018, comparing early retention among ART naïve women and those already on ART. The two cohorts were followed up for 6 months post ANC booking, and this was done in two districts. Data were collected from routine tools used at facility level which include ANC, delivery and ART registers. The Kaplan-Meier survival analysis was used to estimate retention probabilities at 1, 3 and 6 months post-delivery and for retention at delivery proportions were used. Poisson regression was used to investigate factors associated with non-retention at 6 months post ANC booking. Results A total of 388 women were included in the study with median age of 29 years (IQR: 25–34). Two-thirds booked in their second trimester. Retention at 3 and 6 months post ANC booking was 84% (95% CI 80–88) and 73% (95% CI 69–78) respectively. At delivery 81% (95% CI 76–84) were retained in care, 18% lost-to-follow-up and 1% transferred out. In this study we did not find marital status, gestation age, facility location, ART status at ANC booking, to be associated with loss to follow-up. Conclusion In this study, we found low retention at 3, 6 months and delivery, a threat to elimination of Mother-to-child Transmission of HIV in Zimbabwe. Our findings emphasize the need for enhanced interventions to improve early retention such as post-test counselling, patient tracing and visit reminders.

Abstract Background Early adolescence is an important period to lay the foundation for positive sexual health development that can overcome sexual and reproductive health (SRH) challenges faced by very young adolescents (VYAs) as they reach puberty and sexual debut. In this study, we explored the following questions: first, what are the experiences of VYA girls on DREAMS’ Go Girl club participation? Second, how does club participation influence the VYAs SRH knowledge to reduce their risk for HIV and negative sexual health outcomes? Methods This was a qualitative study in which twenty-three in-depth interviews were conducted with VYA girls aged 12–14 years. These girls were enrolled in girl-only clubs in two rural southern districts in Malawi. The clubs were a part of larger comprehensive HIV prevention project called DREAMS (Determined, Resilient, Empowered, AIDS-free, Mentored, and Safe) which provided an evidence-based core package of interventions to VYAs to prevent HIV. Interventions included improved access to key health services, education support, social skills, asset building, and economic strengthening. Narrative inquiry was used to generate first-hand accounts of the girls’ experiences with club participation. Thematic analysis was used to generate themes from the transcribed stories. Results Six main themes were generated: 1) reasons for joining the clubs with desire to learn about SRH as a motivation for joining the clubs.; 2) influence on gender norms and roles whereby participants described a change of gender roles and norms at home; 3) influence on child abuse practices whereby participants reported a decline in child abusive practices at home;4) influence on life skills and social networks whereby participants described learning about networking; 5) support to go back to school whereby out-of-school girls described how economic empowerment of their guardians facilitated their return to school; and 6) influence of clubs on SRH knowledge acquisition and behaviours whereby participants described acquiring knowledge on sexual health issues. Conclusion Girls-only HIV and SRH programs coupled with economic empowerment for their families can be effective in keeping VYA girls in school and improving SRH knowledge and health seeking behavior.

Public aspects of medicine ,RA1-1270 - Abstract
There remains a limited understanding of how men who have sex with men (MSM) and transgender women (TGW) in sub-Saharan Africa (SSA) perceive their risk for HIV and how risk influences behavior during sexual interactions. We performed thematic analysis on in-depth interviews from the qualitative sub-study of HPTN 075 in Kenya, Malawi, and South Africa. Using the Integrated Behavioral Model (IBM) constructs, we found that most MSM and TGW perceived themselves to be at risk for HIV, leading them to regularly engage in safer sexual behaviors. Notably, even though these MSM and TGW perceived themselves to be at risk for HIV, some of them reported engaging in transactional sex, sex under the influence of alcohol, and intentional non-use of condoms. This indicates that HIV risk perception was not always associated with safer sexual behaviors or a reduction in risk behaviors. Attitudes (negative attitudes toward condom use), perceived norms (social pressures), and environment constraints (contextual barriers) were related to MSM and TGW not engaging in safe sexual behavior. Hearing the perspectives of MSM and TGW on their sexual behavior continues to be important for the development and implementation of effective prevention policies and interventions. Eliminating structural barriers such as stigma, discrimination, and criminalization of same-sex sexuality is a crucial prerequisite for the success of interventions to promote sexual health among MSM and TGW in SSA.

Medicine - Abstract
Objectives Disrespectful care, which remains prevalent in low and middle-income countries (LMICs), acts as a barrier to women accessing skilled birth attendance, compromising care when services are available. Building on what was positive in facilities, we aimed to explore lay and healthcare providers’ experience of respectful care to inform future interventions.Setting Five maternity facilities in Mwanza Tanzania and Lilongwe Malawi.Participants 94 participants in Malawi (N=46) and Tanzania (N=48) including 24 women birthing live baby within the previous 12 months; 22 family members and 48 healthcare providers who regularly provided maternity care in the included facilitiesDesign The study was guided by Appreciative Inquiry (AI). Semistructured, one-to-one interviews were conducted between January and December 2019. Interviews were audio-recorded, translated where necessary, transcribed verbatim, and analysed using the framework approach.Results Four main themes describing participants positive experience and their vision of respectful care were identified: (1) empathic healthcare provider–woman interactions including friendly welcome and courteous language, well-timed appropriate care and information sharing, (2) an enabling environment, characterised by improvement of physical environment, the use of screens, curtains and wall partitions for privacy, availability of equipment and provision of incentives to staff, (3) supportive leadership demonstrated by the commitment of the government and facility leaders to provision of respectful care, ensuring availability of guidelines and policies, supportive supervision, reflective discussion and paying staff salaries timely, (4) providers’ attitudes and behaviours characterised by professional values through readiness, compassionate communication and commitment.Conclusion The positive experiences of service users, families and healthcare providers provided insight into key drivers of respectful care in facilities in Tanzania and Malawi. Interventions targeting improved environment and privacy, healthcare provider communication and developing positive leadership structures in facilities could provide the basis for sustained improvement in respectful and dignified maternal and newborn care in LMICs.

Abstract Background Approximately 84,000 children under the age of 15 years are living with HIV in Malawi. Although the survival rate of children living with HIV in Malawi has improved due to the increased availability of antiretroviral medications, these children continue to experience numerous challenges negatively impacting on their mental health. The aim of this study was to investigate the prevalence of, and factors associated with, emotional and behavioural difficulties in children aged between 6 and 12 years living with HIV in Malawi. Methods A random sample of 429 primary caregivers of children living with HIV drawn from the three main administrative regions of Malawi was recruited in a cross-sectional study. They completed a questionnaire about family socio-demographic characteristics, HIV disclosure, and child demographic and clinical characteristics, as well as the Strengths and Difficulties Questionnaire, Life Stress Scale, Support Function Scale, and Impact on Family Scale which were pre-tested and translated into the local Chichewa language. Data were analysed using descriptive statistics and logistic regression. Findings Using the newer band categorisations of the Strengths and Difficulties Questionnaire, parent version, 31% of primary caregivers reported that their child had a slightly raised to very high level of total difficulties. Factors that were associated with difficulties were: primary caregivers’ young age (adjusted odds ratio [aOR] 3.6; 95% confidence interval [CI]: 1.4–9.5); low level of education (aOR 2.6; 95% CI: 1.2–5.7); lack of employment (aOR 2.7; 95% CI: 1.2–5.9); the report of a substantial impact of the child’s illness on the family (3.1; 95% CI: 1.5–6.5); and a low level of family functional support (aOR 2.0; 95% CI: 1.1–4.1). Neither non-disclosure of HIV status nor any of the child demographic or clinical factors were significant in multivariate analysis (p > .0.05). Conclusion Close to one-third of children living with HIV in this study had high scores indicative of emotional and behavioural difficulties. Emotional and behavioural difficulties in children living with HIV were associated with family demographic and psychosocial factors, but not HIV disclosure. Effective policies and programs that promote the mental wellbeing of children living with HIV in Malawi are indicated.

INTRODUCTION: Zimbabwe has a high burden of HIV (i.e., estimated 1.3 million HIV-infected and 13.8% HIV incidence in 2017). In 2017 the country developed and implemented a pilot of HIV case surveillance (CS) based on the 2017 World Health Organisation (WHO) person-centred HIV patient monitoring (PM) and case surveillance guidelines. At the end of the pilot phase an evaluation was conducted to inform further steps. METHODS: The pilot was conducted in two districts (i.e., Umzingwane in Matabeleland South Province and Mutare in Manicaland Province) from August 2017 to December 2018. A mixed-methods cross-sectional study of stakeholders and health facility staff was used to assess the design and operations, performance, usefulness, sustainability, and scalability of the CS system. A total of 13 stakeholders responded to an online questionnaire, while 33 health facility respondents were interviewed in 11 health facilities in the two districts. RESULTS: The HIV CS system was adequately designed for Zimbabwe’s context, integrated within existing health information systems at the facility level. However, the training was minimal, and an opportunity to train the data entry clerks in data analysis was missed. The system performed well in terms of surveillance and informatics attributes. However, viral load test results return was a significant problem. CONCLUSION: The HIV CS system was found useful at the health facility level and should be rolled out in a phased manner, beginning in Manicaland and Matabeleland South provinces. An electronic link needs to be made between the health facilities and the laboratory to reduce viral load test results delays.

This was a cross-sectional study describing HIV testing uptake and ART initiation for pregnant women and HIV-exposed infants after one-off clinical mentorship training in 2013 for nurses in 56 peripheral health-facilities, Zimbabwe. Between 2014-2018, 92% of 106411 pregnant women were HIV tested and 98% of HIV-positive women initiated antiretroviral therapy (ART). There were 15846 HIV-exposed infants, of whom 96% had dried blood spots collected for virologic diagnosis and 51% of those diagnosed HIV-positive initiated ART. In conclusion, this one-off clinical mentorship training in 2013 was associated with consistently high HIV testing and ART initiation in pregnant women and their children.

Medicine - Abstract
ObjectivePeer education is an intervention within the voluntary medical male circumcision (VMMC)–adolescent sexual reproductive health (ASRH) linkages project in Bulawayo and Mount Darwin, Zimbabwe since 2016. Little is known if results extend beyond increasing knowledge. We therefore assessed the extent of and factors affecting referral by peer educators and receipt of HIV testing services (HTS), contraception, management of sexually transmitted infections (STIs) and VMMC services by young people (10–24 years) counselled.DesignA cohort study involving all young people counselled by 95 peer educators during October–December 2018, through secondary analysis of routinely collected data.SettingAll ASRH and VMMC sites in Mt Darwin and Bulawayo.ParticipantsAll young people counselled by 95 peer educators.Outcome measuresCensor date for assessing receipt of services was 31 January 2019. Factors (clients’ age, gender, marital and schooling status, counselling type, location, and peer educators’ age and gender) affecting non-referral and non-receipt of services (dependent variables) were assessed by log-binomial regression. Adjusted relative risks (aRRs) were calculated.ResultsOf the 3370 counselled (66% men), 65% were referred for at least one service. 58% of men were referred for VMMC. Other services had 5%–13% referrals. Non-referral for HTS decreased with clients’ age (aRR: ~0.9) but was higher among group-counselled (aRR: 1.16). Counselling by men (aRR: 0.77) and rural location (aRR: 0.61) reduced risks of non-referral for VMMC, while age increased it (aRR ≥1.59). Receipt of services was high (64%–80%) except for STI referrals (39%). Group counselling and rural location (aRR: ~0.52) and male peer educators (aRR: 0.76) reduced the risk of non-receipt of VMMC. Rural location increased the risk of non-receipt of contraception (aRR: 3.18) while marriage reduced it (aRR: 0.20).ConclusionWe found varying levels of referral ranging from 5.1% (STIs) to 58.3% (VMMC) but high levels of receipt of services. Type of counselling, peer educators’ gender and location affected receipt of services. We recommend qualitative approaches to further understand reasons for non-referrals and non-receipt of services.

Abstract Background The World Health Organisation has recommended that healthcare workers, teachers and community leaders work with parents to support children living with HIV. The aim of this study was to assess the perceptions and experiences of primary caregivers and other care providers such as healthcare workers, teachers, and community leaders regarding their involvement, practice and challenges of HIV disclosure to children aged between 6 and 12 years living with HIV in Malawi. Methods Twelve focus group discussions and 19 one-on-one interviews involving a total of 106 participants were conducted in all three administrative regions of Malawi. The interviews and focus group discussions explored perceptions and experiences regarding involvement, practice and challenges of disclosure of HIV status to children. Data were analysed using thematic analysis. Results Primary caregivers, healthcare workers, teachers, and community leaders all reported that the disclosure of HIV status to children was not well coordinated because each of the groups of participants was working in isolation instead of working as a team. A “working together” model emerged from the data analysis where participants expressed the need for them to work as a team in order to promote safe and effective HIV status disclosure through talking about HIV, sharing responsibility and open communication. Participants reported that by working together, the team members would ensure that the prevalence of HIV disclosure to young children increases and that there would be a reduction in any negative impact of disclosure. Conclusion Global resources are required to better support children living with HIV and their families. Healthcare workers and teachers would benefit greatly from training in working together with families living with HIV and, specifically, training in the disclosure process. Resources, in the form of books and other educational materials, would help them explain HIV and its effective management to children and families.

Abstract Background In 2011 the World Health Organisation recommended that children with a diagnosis of HIV be gradually informed about their HIV status between the ages of 6 and 12 years. However, to date, literature has focused mainly on primary caregiver and child experiences with HIV disclosure, little is known about healthcare workers’ perspectives and practices of HIV status disclosure to children. The aim of this study was to assess healthcare workers’ perspectives and practices regarding the disclosure of HIV status to children aged between 6 and 12 years in Malawi. Methods A cross-sectional survey was used to collect data from 168 healthcare providers working in antiretroviral clinics in all government District and Tertiary Hospitals in Malawi. Participants were asked questions regarding their knowledge, practice, and barriers to HIV disclosure. Data were analysed using binary logistic regression. Results Almost all healthcare workers (98%) reported that it was important to disclose HIV status to children. A significant proportion (37%) reported that they had never disclosed HIV status to a child and about half estimated that the rate of HIV disclosure at their facility was 25% or less. The main barriers to disclosure were lack of training on disclosure (85%) and lack of a standard tool for disclosure (84%). Female healthcare workers (aOR) 2.4; 95% CI: 1.1–5.5) and lack of training on disclosure (aOR 7.7; 95% CI: 3.4–10.7) were independently associated with never having disclosed HIV status to a child. Conclusions This study highlights the need for providing appropriate training in HIV disclosure for healthcare workers and the provision of standardised disclosure materials.

Public aspects of medicine ,RA1-1270 - Abstract
Abstract Background The perception of male involvement (MI) in maternal child health services is multifaceted and differs among varying programs and populations. In the Prevention of Mother to Child Transmission (PMTCT) context, MI includes men’s attendance at antenatal care (ANC) clinics, undertaking an HIV tests within the ANC and financial and psychological support. Contexualising the definition of MI is fundamental in the development of MI in PMTCT policy and interventions. The objective of this study was to explore the perceptions of men, women and health care workers on male partner involvement in PMTCT services in Malawi. Methods A qualitative descriptive study was conducted at South Lunzu Health Centre (SLHC) in Blantyre, Malawi from December 2012 to January 2013. We conducted s Key Informant Interviews (KIIs) with 6 health care workers and moderated four Focus Group Discussions (FGDs) among 18 men and 17 pregnant women attending antenatal care at SLHC. We divided FGDs participants according to sex and age. We digitally recorded all FGDs and KIIs and simultaneously transcribed and translated verbatim into English. We employed thematic analysis to identify codes and themes. Results Men and women described MI in PMTCT as either a) Positive participation or b) Negative participation. Positive participation included total involvement of the male partner in PMTCT interventions, reminding the spouse of clinic and treatment schedules, and resource provision. Health care workers described MI as either a) Involvement along the pregnancy continuum or b) Passive Involvement. Participants’ preferred positive involvement of male partners. Conclusions There are multiple perceptions of MI in PMTCT with participants preferring positive involvement. There is a need to have a uniform description of MI in PMTCT to optimize development of strategies and interventions that accommodate and optimize MI in PMTCT. A uniform description will be useful in assessing a country’s progress towards achieving MI in PMTCT goals.

Medicine ,Science - Abstract
The World Health Organisation (WHO) recommends that children living with HIV should be informed about their HIV status within the ages of 6 to 12 years using age-appropriate resources. The aim of this study was to assess the socio-demographic, clinical and psychosocial factors associated with primary caregivers' decisions to disclose HIV to children living with HIV aged 6 to 12 years in Malawi. A cross-sectional study of 429 primary caregivers of children living with HIV were systematically recruited from all regions of the country. Information on HIV disclosure, family and child socio-demographic characteristics, child clinical characteristics, and child and family psychosocial characteristics was collected using validated instruments. Logistic regression was used to analyse data. The prevalence of non-disclosure of HIV status to children was 64 per cent. Concerns about the child's inability to cope with the news (29%), a lack of knowledge on how to disclose HIV status (19%), and fear of stigma and discrimination (17%) were the main reasons for non-disclosure. On multivariate analysis, the odds of non-disclosure were higher among primary caregivers who were farmers (aOR 3.0; 95% CI: 1.1-8.4), in younger children (6-8 years) (aOR 4.1; 95% CI: 2.3-7.4), in children who were in WHO HIV clinical stage one (aOR 3.8; 95% CI: 1.4-10.2), and in children who were not asking why they were taking ARVs (aOR 2.9; 95% CI: 1.8-4.8). On the other hand, nondisclosure of HIV status was less likely in underweight children (aOR 0.6; 95% CI: 0.3-0.9). Many children living with HIV in Malawi are unaware of their HIV status. Non-disclosure is associated with a number of clinical and demographic characteristics. The findings highlight the need to provide guidance and support to primary caregivers to help them to effectively disclose HIV status to their children.

Medicine ,Science - Abstract
BackgroundGlobally, ten percent of new HIV infections are among children and most of these children acquire infection through mother-to-child transmission. To prevent this, lifelong ART among pregnant and breast feeding (PBF) women living with HIV, irrespective of the WHO clinical stage, was adopted (option B+). There is limited cohort-wise assessment of VL testing among women on 'option B+'.ObjectiveAmong a pregnancy cohort on antiretroviral therapy in public hospitals and clinics of Mazowe district, Zimbabwe (2017), to determine the i) proportion undergoing VL testing anytime up to six months post child birth and associated factors; ii) turnaround time (TAT) from sending the specimen to results receipt and VL suppression among those undergoing VL testing.MethodsThis was a cohort study involving secondary programme data. Modified Poisson regression using robust variance estimates was used to determine the independent predictors of VL testing.ResultsOf 1112 women, 354 (31.8%, 95% CI: 29.2-34.6) underwent VL testing: 113 (31.9%) during pregnancy, 124 (35%) within six months of child birth and for 117 (33.1%), testing period was unknown. Of 354, VL suppression was seen in 334 (94.4%) and 13 out of 20 with VL non-suppression underwent repeat VL testing. Among those with available dates (125/354), the median TAT was 93 days (IQR 19.3-255). Of 1112, VL results were available between 32 weeks and child birth in 31 (2.8%) women. When compared to hospitals, women registered for antenatal care in clinics were 36% less likely to undergo VL testing [aRR: 0.64 (95% CI: 0.53, 0.76)].ConclusionAmong women on option B+, the uptake of HIV VL testing was low with unacceptably long TAT. VL suppression among those tested was satisfactory. There is an urgent need to prioritize VL testing among PBF women and to consider use of point of care machines. There is a critical need to strengthen the recording and local utilisation of routine clinic data in order to successfully monitor progress of healthcare services provided.

Background: Evidence-based antenatal care is one cornerstone in Safe Motherhood and educated and confident midwives remain to be optimal caregivers in Africa. Confidence in antenatal midwifery skills is important and could differ depending on the provision of education among the training institutions across Africa. Objective: The aim of the study was to describe and compare midwifery students’ confidence in basic antenatal skills, in relation to age, sex, program type and level of program. Methods: A survey in seven sub-Saharan African countries was conducted. Enrolled midwifery students from selected midwifery institutions in each country presented selfreported data on confidence to provide antenatal care. Data were collected using a selfadministered questionnaire. The questionnaire consisted of 22 antenatal skills based on the competency framework from the International Confederation of Midwives. The skills were grouped into three domains; Identify fetal and maternal risk factors and educate parents; Manage and document emergent complications and Physical assessment and nutrition. Results: In total, 1407 midwifery students from seven Sub-Saharan countries responded. Almost one third (25-32%) of the students reported high levels of confidence in all three domains. Direct entry programs were associated with higher levels of confidence in all three domains, compared to post-nursing and double degree programs. Students enrolled at education with diploma level presented with high levels of confidence in two out of three domains. Conclusions: A significant proportion of student midwives rated themselves low on confidence to provide ANC. Midwifery students enrolled in direct entry programs reported higher levels of confidence in all domains. It is important that local governments develop education standards, based on recommendations from the International Confederation of midwives. Further research is needed for the evaluation of actual competence.

- Abstract
Introduction: The COVID-19 pandemic has globally impacted health service access, delivery and resources. There are limited data regarding the impact on the prevention of mother to child transmission (PMTCT) service delivery in low-resource settings. Neotree (www.neotree.org) combines data collection, clinical decision support and education to improve care for neonates. Here we evaluate impacts of COVID-19 on care for HIV-exposed neonates. Methods: Data on HIV-exposed neonates admitted to the neonatal unit (NNU) at Sally Mugabe Central Hospital, Zimbabwe, between 01/06/2019 and 31/12/2021 were analysed, with pandemic start defined as 21/03/2020 and periods of industrial action (doctors (September 2019-January 2020) and nurses (June 2020-September 2020)) included, resulting in modelling during six time periods: pre-doctors’ strike (baseline); doctors’ strike; post-doctors’ strike and pre-COVID; COVID and pre-nurses’ strike ; nurses’ strike; post nurses’ strike. Interrupted time series models were used to explore changes in indicators over time. Results: Of 8,333 neonates admitted to the NNU, 904 (11%) were HIV-exposed. Mothers of 706/765 (92%) HIV-exposed neonates reported receipt of antiretroviral therapy (ART) during pregnancy. Compared to the baseline period when average admissions were 78 per week (95% confidence interval (CI) 70-87), significantly fewer neonates were admitted during all subsequent periods until after the nurses’ strike, with the lowest average number during the nurses’ strike (28, 95% CI 23-34, p0.22) in numbers of admissions or mortality by HIV exposure status. Fewer HIV-exposed neonates received a PCR test during the pandemic (23%) compared to the pre-pandemic periods (40%) (RR 0.59, 95% CI 0.41-0.84, pConclusion: While antiretroviral prophylaxis for HIV-exposed neonates remained high throughout, concerning data on low admissions and increased mortality, similar in HIV-exposed and unexposed neonates, and reduced HIV testing, suggest some aspects of care may have been compromised due to indirect effects of the pandemic.
