Profile and outcomes of management of patients admitted to obstetric high care unit in a tertiary academic hospital in Gauteng Province, South Africa.

The aim of this study was to describe maternal characteristics and pregnancy outcomes of women admitted in a dedicated obstetric high care unit (OHCU) in a tertiary hospital in Gauteng province, South Africa. The study involved review of clinical records of women admitted to OHCU between January and June 2016. Data collected included maternal demographic data, indication for admission, management and outcomes. A total of 4 637 of women gave birth and 114 (2.5%) were admitted to the OHCU during this period. Majority (90, 78.9%) were younger than 35 (mean 29.6) years with 32(28.1%), in their first pregnancy. Obstetric related indications for OHCU admission were mainly, pre-eclampsia and related complications (89, 78.1%), followed by obstetric haemorrhage (32, 28.1%). Cardiac disease, 14(12.3%) and pneumonia 6(5.3%) were the most common non-obstetrics indications for admission. Majority of patients stayed in OHCU for an average of 24-48 hours and were discharged alive (99.86.8%). Only 11(9.6%) were transferred to ICU and complications related to cardiac diseases were the most common reason for the transfer. Preeclampsia, obstetric hemorrhage and cardiac related complications are the most common reasons for OHCU and ICU admissions however most of these condition can be successfully managed in OHCU.

Infant HIV Testing Amid the COVID-19 Pandemic and Evolving PMTCT Guidelines in Johannesburg, South Africa.

Background: The COVID-19 pandemic impacted HIV programmes with the diversion of resources and lockdown measures. We assessed the impact of COVID-19 on infant HIV diagnosis in the context of updated 2019 prevention of mother-to-child transmission of HIV (PMTCT) guidelines in Johannesburg, South Africa. Methods: HIV PCR data for children <2 years were extracted from the National Health Laboratory Service database from October 2018 to September 2021, inclusive. Trends in the total number of tests performed and the total number of children with HIV diagnosed, stratified by age, were determined to assess the effect of different COVID-19 lockdown levels and updated guidelines. Results: When comparing three 12-month periods ending September 2019−2021, respectively, the total number of HIV PCR tests performed increased (from 41 879 to 47 265 to 56 813), and the total number of children with HIV decreased (from 659 to 640 to 620), year-on-year. There was a substantial increase in 6-month testing in response to updated guidelines. Excluding 6-month testing, the year-on-year increase in total tests was maintained with birth and 10-week testing closely approximating total live births to women living with HIV. A decrease in the total number of children with HIV diagnosed was noted in Q2 2020, coinciding with the most restrictive lockdown, followed by a rebound in cases. Conclusions: Despite the restrictions and diversion of resources associated with COVID-19, there was a successful implementation of PMTCT guideline updates and minimal disruption to infant HIV testing. However, much work remains in order to achieve the elimination of mother-to-child transmission of HIV.

Implementation of a PMTCT programme in a high HIV prevalence setting in Johannesburg, South Africa: 2002-2015.

BACKGROUND: Great strides have been made in decreasing paediatric human immunodeficiency virus (HIV) infections, especially in sub-Saharan Africa. In South Africa, new paediatric HIV infections decreased by 84% between 2009 and 2015. This achievement is a result of a strong political will and the rapid evolution of the country's prevention of mother-to-child transmission (PMTCT) guidelines. OBJECTIVES: In this paper we report on the implementation of a large PMTCT programme in Soweto, South Africa. METHODS: We reviewed routinely collected PMTCT data from 13 healthcare facilities, for the period 2002-2015. Antiretroviral therapy (ART) coverage among pregnant women living with HIV (PWLHIV) and the mother-to-child transmission (MTCT) rate at early infant diagnosis were evaluated. RESULTS: In total, 360 751 pregnant women attended the facilities during the review period, and the HIV prevalence remained high throughout at around 30%. The proportion of PWLHIV presenting with a known HIV status increased from 14.3% in 2009 when the indicator was first collected to 45% in 2015, p < 0.001. In 2006, less than 10% of the PWLHIV were initiated on ART, increasing to 88% by 2011. The MTCT rate decreased from 6.9% in 2007 to under 1% from 2013 to 2015, p < 0.001. CONCLUSION: The achievements in decreasing paediatric HIV infections have been hailed as one of the greatest public health achievements of our times. While there are inherent limitations with using routinely collected aggregate data, the Soweto data reflect progress made in the implementation of PMTCT programmes in South Africa. Progress with PMTCT has, however, not been accompanied by a decline in HIV prevalence among pregnant women.

Trends in maternal deaths in HIV-infected women, on a background of changing HIV management guidelines in South Africa: 1997 to 2015.

INTRODUCTION: As work begins towards the Sustainable Development Goal target of reducing the global maternal mortality ratio (MMR) to less than 70 deaths per 100,000 live births by 2030, much needs to be done in ending preventable maternal deaths. After 1990, South Africa experienced a reversal of gains in decreasing maternal mortality, with an increase in HIV-related maternal deaths. In this study, we assessed trends in maternal mortality in HIV-infected women, on a background of an evolving HIV care programme. METHODS: This was a cross-sectional, retrospective record review of maternal deaths in the obstetrics unit at Chris Hani Baragwanath Academic Hospital, in Johannesburg, South Africa, a referral hospital in a high HIV prevalence setting where the prevalence among pregnant women has plateaued around 29.0% for the past decade. Trends in HIV diagnosis and management in pregnancy, and causes of maternal deaths in HIV-infected women were analysed over different time periods (1997 to 2003, 2004 to 2009, 2010 to 2012, and 2013 to 2015) reflecting major guideline changes. RESULTS: From January 1997 to December 2015, there were 692 maternal deaths in the obstetrics unit. Of the 490 (70.8%) maternal deaths with a documented HIV status, 335 (68.4%) were HIV-infected. A Chi-squared test for trends showed that the institutional MMR (iMMR) in women known to be HIV-infected peaked in the period 2004 to 2009 at 380 (95% CI 319 to 446) per 100,000 live births, with a decline to 267 (95% CI 198 to 353) in 2013 to 2015, p = 0.049. This decrease coincided with changes in the South African HIV management guidelines, mainly increased availability of antiretroviral therapy (ART). Non-pregnancy related infections were the leading cause of death throughout the review period, accounting for 61.5% (206/335) of deaths. Only 23.3% (78/335) of the women who died were on ART at the time of death, this in the context of advanced immune suppression and an overall median CD4 count of 136 cells/µl (interquartile ranges (IQR) 45 to 301). CONCLUSION: In this 19-year review of maternal deaths in Johannesburg, South Africa, there was evidence of a decrease in the iMMR among HIV-infected women, but it remains unacceptably high. Efforts to address drivers of mortality and barriers to accessing ART need to be accelerated if we are to see substantial decreases in maternal mortality.

Infant feeding knowledge, perceptions and practices among women with and without HIV in Johannesburg, South Africa: a survey in healthcare facilities.

BACKGROUND: South Africa has a history of low breastfeeding rates among women with and without Human Immunodeficiency Virus (HIV). In this study, we assessed infant feeding knowledge, perceptions and practices among pregnant and postpartum women with and without HIV, in the context of changes in infant feeding and Prevention of Mother-to-Child Transmission of HIV (PMTCT) guidelines. METHODS: This was a cross-sectional survey conducted from April 2014 to March 2015 in 10 healthcare facilities in Johannesburg, South Africa. A total of 190 pregnant and 180 postpartum women (74 and 67, respectively, were HIV positive) were interviewed using a semi-structured questionnaire. Multiple regression analyses assessed factors associated with an intention to exclusively breastfeed, and exclusive breastfeeding of infants less than six months of age. RESULTS: Women with HIV had better overall knowledge on safe infant feeding practices, both in general and in the context of HIV infection. There were however gaps in knowledge among women with and without HIV. Information from healthcare facilities was the main source of information for all groups of women in the study. A greater percentage of women without HIV 80.9% (93/115), reported an intention to exclusively breastfeed, compared to 64.9% (48/74) of women with HIV, p = 0.014. Not having HIV was positively associated with a reported intention to breastfeed, Adjusted Odds Ratio (AOR) 3.60, 95% CI 1.50, 8.62. Other factors associated with a reported intention to exclusively breastfeed were prior breastfeeding experience and higher knowledge scores on safe infant feeding practices in the context of HIV infection. Among postpartum women, higher scores on general knowledge of safe infant feeding practices were positively associated with reported exclusive breastfeeding, AOR 2.18, 95% CI 1.52, 3.12. Most women perceived that it was difficult to exclusively breastfeed and that cultural factors were a barrier to exclusive breastfeeding. CONCLUSIONS: While a greater proportion of women are electing to breastfeed, HIV infection and cultural factors remain an important influence on safe infant feeding practices. Healthcare workers are the main source of information, and highlight the need for accurate and consistent messaging for both women with and without HIV.

Patient factors to target for elimination of mother-to-child transmission of HIV.

BACKGROUND: There is great impetus to achieve elimination of mother-to-child transmission of HIV (eMTCT) by 2015, and part of this is to identify factors to target to achieve the goal. This study thus identified key patient factors for MTCT in a high HIV prevalence setting in Johannesburg, South Africa. Between November 2010 and May 2012, we conducted a case-control study among HIV-infected women with HIV-infected (cases) and uninfected (controls) infants diagnosed around six weeks of age as part of routine, early infant diagnosis. Mothers and infants were identified through registers in six healthcare facilities that provide antenatal, postpartum and HIV care. Structured interviews were conducted with a focus on history of HIV infection, antenatal, intrapartum and immediate postpartum management of the mother-infant pair. Patient-related risk factors for MTCT were identified. RESULTS: A total of 77 women with HIV-infected infants and 154 with -uninfected infants were interviewed. Among HIV-infected cases, 13.0% of the women knew their HIV status prior to conception, and 83.1% reported their pregnancies as unplanned. Antenatal antiretroviral coverage was high in the control group - only 1/154 (0.7%) reported receiving no prophylaxis or treatment compared with 17/74 (22.9%) of cases. In multivariate analysis, key patient-related risks for HIV transmission were: unknown HIV status prior to conception (adjusted odds ratio [AOR] = 6.6; 95% CI = 2.4 - 18.4; p < 0.001); accessing antenatal care after 20 weeks gestation (AOR = 4.3; 95% CI = 2.0 - 9.3; p < 0.001); less than 12 years of formal education (AOR = 3.4; 95% CI = 1.6 - 7.5; p = 0.002); and unplanned pregnancy (AOR = 2.7; 95% CI = 1.2 to 6.3; p = 0.022). Mean age at first HIV test was 6.6 weeks (SD = 3.5) for infants who were diagnosed as HIV-infected, and the mean age at antiretroviral treatment initiation was 10.8 weeks (SD = 4.4). HIV-uninfected infants were diagnosed at a mean age of 6.0 weeks (SD = 0.2). CONCLUSIONS: Undiagnosed maternal HIV infection prior to conception, unplanned pregnancies, delays in accessing antenatal care, and low levels of education were the most significant patient risk factors associated with MTCT. While the emphasis has been on increasing availability and coverage of efficacious antiretroviral regimens, and strengthening health systems within eMTCT initiatives, there is a need to also address patient-related factors if we are to achieve eMTCT goals.

Assessment of service availability and health care workers' opinions about young women's sexual and reproductive health in Soweto, South Africa.

Young women in South Africa experience high HIV and unintended pregnancy rates. Health care workers' (HCWs') opinions about sexual and reproductive health (SRH) issues impact young women's ability to access SRH services. We explored HCW opinions through interviews with a purposive sample of 29 HCWs in three primary health clinics in Soweto, South Africa and examined service availability through facility assessments. Most HCWs believed young women should not have sex before marriage and thought that young women ignore information they receive about HIV and pregnancy prevention. HCWs acknowledged outside factors influencing young women's ability to protect themselves. Most thought injectables were the most appropriate contraception for young women; all recognized the importance of condoms for dual protection. Some services were only reported to be provided to those over 18 years. HCWs may benefit from workshops providing technical and policy information and values clarification exercises highlighting the impact of opinions on service provision.

The reliability of point-of-care CD4 testing in identifying HIV-infected pregnant women eligible for antiretroviral therapy.

OBJECTIVE: Point-of-care (POC) CD4 testing may play an important role in identifying individuals who require antiretroviral therapy (ART), particularly during pregnancy. However, there have been no evaluations of POC CD4 testing in pregnant women. We compared the performance of the PIMA POC analyzer with laboratory-based testing in identifying pregnant women eligible for ART. DESIGN AND METHODS: Participants were 296 consecutive HIV-infected pregnant women in a prevention of mother-to-child transmission of HIV service in Johannesburg, South Africa. Parallel CD4 cell count testing was done using capillary specimens for the PIMA analyzer and venous samples for flow cytometry. RESULTS: The median age was 28 years, and the median gestation was 19 weeks (interquartile range, IQR, 16-24). The median PIMA and laboratory CD4 cell counts were 352 cells (IQR, 251-491) cells per cubic millimeter and 367 (IQR, 251-524) cells per cubic millimeter, respectively. The mean difference between the PIMA and the laboratory CD4 results was 20.5 (95% confidence interval: 11.7 to 29.3) cells per cubic millimeter with limits of agreement from -133.9 to 175.0. The PIMA correctly identified 93% of women who were ART eligible based on a laboratory CD4 ≤350 cells per cubic millimeter. There was no evidence of variability in the agreement of PIMA and laboratory-based CD4 testing by participant age or gestation. CONCLUSIONS: These data show good agreement between the PIMA analyzer and laboratory-based CD4 enumeration, comparable to levels in nonpregnant HIV-infected adults. The reliability of the PIMA did not vary with gestation despite the hemodilution of pregnancy. POC CD4 technologies may be used to identify ART-eligible women in prevention of mother-to-child transmission of HIV settings to help promote the rapid initiation of ART.
