    Cohort Profile: The Western Cape Pregnancy Exposure Registry (WCPER)
    (2022-06) Kalk, Emma; Heekes, Alexa; Slogrove, Amy; Phelanyane, Florence; Davies, Mary-Ann; Myer, Landon; Euvrard, Jonathan; Kroon, Max; Petro, Greg; Fieggen, Karen; Stewart, Chantal; Rhoda, Natasha; Gebhardt, Stefan; Osman, Ayesha; Anderson, Kim; Boulle, Andrew; Mehta, Ushma
    Purpose: The Western Cape Pregnancy Exposure Registry (PER) was established at two public sector healthcare sentinel sites in the Western Cape province, South Africa, to provide ongoing surveillance of drug exposures in pregnancy and associations with pregnancy outcomes. Participants: Established in 2016, all women attending their first antenatal visit at primary care obstetric facilities were enrolled and followed to pregnancy outcome regardless of the site (ie, primary, secondary, tertiary facility). Routine operational obstetric and medical data are digitised from the clinical stationery at the healthcare facilities. Data collection has been integrated into existing services and information platforms and supports routine operations. The PER is situated within the Provincial Health Data Centre, an information exchange that harmonises and consolidates all health-related electronic data in the province. Data are contributed via linkage across a unique identifier. This relationship limits the missing data in the PER, allows validation and avoids misclassification in the population-level data set. Findings to date: Approximately 5000 and 3500 pregnant women enter the data set annually at the urban and rural sites, respectively. As of August 2021, >30 000 pregnancies have been recorded and outcomes have been determined for 93%. Analysis of key obstetric and neonatal health indicators derived from the PER are consistent with the aggregate data in the District Health Information System. Future plans: This represents significant infrastructure, able to address clinical and epidemiological concerns in a low/middle-income setting.

    Counting every stillbirth and neonatal death through mortality audit to improve quality of care for every pregnant woman and her baby
    (BioMed Central Ltd, 2015) Kerber, Katherine J; Mathai, Matthews; Lewis, Gwyneth; Flenady, Vicki; Erwich, Jan Jaap; Segun, Tunde; Aliganyira, Patrick; Abdelmegeid, Ali; Allanson, Emma; Roos, Nathalie; Rhoda, Natasha; Lawn, Joy; Pattinson, Robert
    BACKGROUND: While there is widespread acknowledgment of the need for improved quality and quantity of information on births and deaths, there has been less movement towards systematically capturing and reviewing the causes and avoidable factors linked to deaths, in order to affect change. This is particularly true for stillbirths and neonatal deaths which can fall between different health care providers and departments. Maternal and perinatal mortality audit applies to two of the five objectives in the Every Newborn Action Plan but data on successful approaches to overcome bottlenecks to scaling up audit are lacking. METHODS: We reviewed the current evidence for facility-based perinatal mortality audit with a focus on low- and middle-income countries and assessed the status of mortality audit policy and implementation. Based on challenges identified in the literature, key challenges to completing the audit cycle and affecting change were identified across the WHO health system building blocks, along with solutions, in order to inform the process of scaling up this strategy with attention to quality. RESULTS: Maternal death surveillance and review is moving rapidly with many countries enacting and implementing policies and with accountability beyond the single facility conducting the audits. While 51 priority countries report having a policy on maternal death notification in 2014, only 17 countries have a policy for reporting and reviewing stillbirths and neonatal deaths. The existing evidence demonstrates the potential for audit to improve birth outcomes, only if the audit cycle is completed. The primary challenges within the health system building blocks are in the area of leadership and health information. Examples of successful implementation exist from high income countries and select low- and middle-income countries provide valuable learning, especially on the need for leadership for effective audit systems and on the development and the use of clear guidelines and protocols in order to ensure that the audit cycle is completed. CONCLUSIONS: Health workers have the power to change health care routines in daily practice, but this must be accompanied by concrete inputs at every level of the health system. The system requires data systems including consistent cause of death classification and use of best practice guidelines to monitor performance, as well as leaders to champion the process, especially to ensure a no-blame environment, and to access change agents at other levels to address larger, systemic challenges.

    Early clinical signs in neonates with hypoxic ischemic encephalopathy predict an abnormal amplitude-integrated electroencephalogram at age 6 hours
    (BioMed Central Ltd, 2013) Horn, Alan; Swingler, George; Myer, Landon; Linley, Lucy; Raban, Moegammad; Joolay, Yaseen; Harrison, Michael; Chandrasekaran, Manigandan; Rhoda, Natasha; Robertson, Nicola
    BACKGROUND: An early clinical score predicting an abnormal amplitude-integrated electroencephalogram (aEEG) or moderate-severe hypoxic ischemic encephalopathy (HIE) may allow rapid triage of infants for therapeutic hypothermia. We aimed to determine if early clinical examination could predict either an abnormal aEEG at age 6 hours or moderate-severe HIE presenting within 72 hours of birth. METHODS: Sixty infants [greater than or equal to] 36 weeks gestational age were prospectively enrolled following suspected intrapartum hypoxia and signs of encephalopathy. Infants who were moribund, had congenital conditions that could contribute to the encephalopathy or had severe cardio-respiratory instability were excluded. Predictive values of the Thompson HIE score, modified Sarnat encephalopathy grade (MSEG) and specific individual signs at age 3-5 hours were calculated. RESULTS: All of the 60 infants recruited had at least one abnormal primitive reflex. Visible seizures and hypotonia at 3-5 hours were strongly associated with an abnormal 6-hour aEEG (specificity 88% and 92%, respectively), but both had a low sensitivity (47% and 33%, respectively). Overall, 52% of the infants without hypotonia at 3-5 hours had an abnormal 6-hour aEEG. Twelve of the 29 infants (41%) without decreased level of consciousness at 3-5 hours had an abnormal 6-hour aEEG (sensitivity 67%; specificity 71%). A Thompson score [greater than or equal to] 7 and moderate-severe MSEG at 3-5 hours, both predicted an abnormal 6-hour aEEG (sensitivity 100 vs. 97% and specificity 67 vs. 71% respectively). Both assessments predicted moderate-severe encephalopathy within 72 hours after birth (sensitivity 90%, vs. 88%, specificity 92% vs. 100%). The 6-hour aEEG predicted moderate-severe encephalopathy within 72 hours (sensitivity 75%, specificity 100%) but with lower sensitivity (p = 0.0156) than the Thompson score (sensitivity 90%, specificity 92%). However, all infants with a normal 3- and 6-hour aEEG with moderate-severe encephalopathy within 72 hours who were not cooled had a normal 24-hour aEEG. CONCLUSIONS: The encephalopathy assessment described by the Thompson score at age 3-5 hours is a sensitive predictor of either an abnormal 6-hour aEEG or moderate-severe encephalopathy presenting within 72 hours after birth. An early Thompson score may be useful to assist with triage and selection of infants for therapeutic hypothermia.

    Neonatal Mortality in the Cape Town Metro West Geographical Service Area 2014-2017
    (2020) Nelson, Candice Afonso; Hendricks, Michael; Rhoda, Natasha; Masu, Adelaide
    Background Each neonatal death counts, as recognised by the Every Newborn Action Plan (ENAP). This is an important aspect in attaining the third Sustainable Development Goal by 2030. Accurate neonatal mortality data as well as an understanding of the causality and context is essential to plan interventions to reduce neonatal deaths and attain the third Sustainable Development Goals (SDG) of a neonatal mortality rate of less than 12 per 1000 livebirths by 2035. Objectives The objectives of this study were: (i) to determine neonatal mortality occurring in and out of health facilities in the Metro West GSA using the three audit programmes; Perinatal Problem Identification Programme (PPIP), Child Healthcare Problem Identification Programme (Child PIP) and Forensic Pathology Services (ii) to ascertain the cause of death specific neonatal mortality (iii) to describe the avoidable factors in each death as coded by the three audit programmes (iv) to make recommendations for the alignment of existing audit databases to obtain accurate neonatal statistics for the Metro West GSA. Methods This was a retrospective descriptive study of neonatal deaths undertaken in the public healthcare setting in the Cape Town Metro West GSA from January 2014 till December 2017. Existing data from PPIP, Child PIP and the CDR/FPS was used. Neonatal deaths were defined as in the first 28 days of life where there had been signs of life at delivery and a birthweight greater than 500g. Neonatal deaths were excluded where birth had occurred outside of the GSA or in the private health care setting. The audit data with regards to cause of death and avoidable or modifiable factors was obtained for each death. Results From a total of 134843 live deliveries, 1243 neonatal deaths were identified: 976(78%) from PPIP, 58(5%) from Child PIP and 209 (17%) from CDR/FPS. Sixteen per cent of the deaths occurred outside of healthcare facilities. The neonatal mortality rate (NMR) for PPIP was 7.2, Child PIP 0.43 and CDR 1,6 per 1000 livebirths. When the audit systems were combined, the annual NMR over the study period varied from 8.05 to 10.1 with a mean of 9.2 per 1000 livebirths over the entire period. Seventy-eight per cent of the deaths occurred in the early neonatal period with a mean early neonatal mortality rate of 7.2 per 1000 livebirths. The mean late NMR was 2 per 1000 livebirths. Where all neonatal deaths were considered for those more than 500g, the main cause of death was immaturity related, then infection related followed by congenital disorders and then hypoxia related. Seventy-four per cent of deaths occurred in those less than 2500g at birth and 41% were less than 1000g and defined as extremely low birthweight. In the group of neonates greater than 1000g, the main cause of death was infection related deaths, closely followed by congenital disorders and then hypoxia, followed by immaturity. Most of infection related deaths were collected by the CDR and Child PIP. A third of Child PIP and PPIP deaths and half of the CDR deaths were coded as avoidable. The prevalence of deaths due to abandonment either by passive or active neonaticide contributed towards the higher proportion of preventable deaths in the CDR group. Conclusions The burden of deaths due to immaturity is high and may be attributed to the finding that 41% of neonatal deaths were in the ELBW group. Current viability criteria that aim at optimum use of resources may improve survival amongst this group. Infection related deaths were shown by this study to have a greater burden than recorded from PPIP data; most of these deaths were derived from Child PIP and CDR data. Also, where 10% of neonatal deaths were sudden unexpected deaths (SUDIs), a better understanding and definition of this group is urgently required as many of these deaths were subsequently found to be secondary to lower respiratory infections. It is further relevant that where 20% of CDR deaths or 3% of all the study deaths were due to active and passive neonaticide, this entity should be monitored and investigated. The study showed that the GSA has achieved the SDG for NMR of less than 12 per 1000 livebirth. However, a mean NMR of 9.2 per 1000 livebirths is not comparable to other upper middle-income countries. As 38% of the deaths were coded as avoidable, appropriate programmes to address these factors could reduce the NMR to 5.7 per 1000 livebirths. A strong recommendation from this study would be to use all three audit systems to calculate the NMR, understand the causes of neonatal deaths and plan programmes to improve neonatal survival in this GSA.

    Outcomes of preterm infants discharged early from a South African Kangaroo Mother Care Unit
    (2019) Williams, Sadeeka; Rhoda, Natasha; Els, Ilse
    Background: Over 15 million preterm babies are born annually and are the leading contributor to neonatal deaths. Kangaroo Mother Care (KMC), incorporating skin-to-skin care, breastfeeding, early discharge and close follow up, decreases morbidity and mortality in preterm and low-birth-weight infants. Few recent South African studies have looked at outcomes of KMC beyond the neonatal period. Aim: The primary objective was to describe the post-discharge clinical course of KMC infants over six months. The secondary objectives were to correlate neonatal and maternal characteristics pre-discharge to outcomes – mortality and morbidity. Setting: George Hospital is the regional hospital for the Eden and Central Karoo districts, with its tertiary referral centre 400km away in Cape Town. In these areas, poverty and teenage pregnancies result in more than a quarter of learners dropping out of school before completing Grade 12. The hospital has intensive care, high care and KMC units. Methods: This was a retrospective descriptive study which reviewed folders of neonates discharged from KMC in 2013. Neonates with birth weights of 2000g or more and neonates referred out were excluded. Hospital readmissions were used as a proxy for morbidity and a descriptive analysis was done. Results: Fifty-two infant records were reviewed. Thirteen infants (25%) accounted for 21 readmissions. Six readmissions occurred in winter. There were significant associations between being readmitted and birth weight and breastfeeding. Thirty-five of the 52 infants were alive at six months. None were known to have died. Conclusion: Larger prospective studies on KMC infant outcomes are needed in South Africa
