"Getting pregnant during the COVID 19 was a big risk because getting the help from the clinic was not easy": COVID-19 experiences of women and healthcare providers in Harare, Zimbabwe. (preprint)

Background The COVID-19 pandemic and associated measures may have disrupted delivery of maternal and neonatal healthcare 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. Methods 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 the modified grounded theory approach. Results While eight antenatal care contacts are recommended by Zimbabwes Ministry of Health and Child Care, women reported only being able to access two contacts. At antenatal booking, women were told to return at onset of labour; subsequent visits were suspended. Healthcare workers reported this reduction in antenatal attendance was a result of limited availability of personal protective equipment and fear that patients and services providers would contract SARS-CoV-2. 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 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 were faced with multiple challenges, they continued to attempt to access services after delivery. Conclusions The COVID-19 pandemic disrupted provision and uptake of PMTCT services; antenatal care contacts were significantly reduced, home deliveries increased and babies born at home missed out on the necessary ARV prophylaxis. These findings underline the importance of investing in robust health systems that are able to respond to emergency situations to ensure continuity of essential HIV prevention, treatment and care services.

Effects of the COVID-19 pandemic on the outcomes of HIV-exposed neonates: a Zimbabwean tertiary hospital experience (preprint)

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<0.001). Across all time periods excluding the nurses strike, average mortality was 20% (95% CI 18-21), but rose to 34% (95% CI 25, 46) during the nurses’ strike.  There was no evidence for heterogeneity (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<0.001). The proportion of HIV-exposed neonates who received antiretroviral prophylaxis during admission was high throughout, averaging between 84% and 95% in each time-period. Conclusion: 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.
