Counting every stillbirth and neonatal death through mortality audit to improve quality of care for every pregnant woman and her baby

Abstract: 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. 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. 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. 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.

Causes of perinatal mortality and associated maternal complications in a South African province: challenges in predicting poor outcomes

Abstract: Background: Reviews of perinatal deaths are mostly facility based. Given the number of women who, globally, deliver outside of facilities, this data may be biased against total population data. We aimed to analyse population based perinatal mortality data from a LMIC setting (Mpumalanga, South Africa) to determine the causes of perinatal death and the rate of maternal complications in the setting of a perinatal death. Methods: A secondary analysis of the South African Perinatal Problems Identification Program (PPIP) database for the Province of Mpumalanga was undertaken for the period October 2013 to January 2014, inclusive. Data on each individual late perinatal death was reviewed. We examined the frequencies of maternal and fetal or neonatal characteristics in late fetal deaths and analysed the relationships between maternal condition and fetal and/or neonatal outcomes. IBM SPSS Statistics 22.0 was used for data analysis. Results: There were 23503 births and 687 late perinatal deaths (stillbirths of ≥ 1000gr or ≥ 28 weeks gestation and early neonatal deaths up to day 7 of neonatal life) in the study period. The rate of maternal complication in macerated stillbirths, fresh stillbirths and early neonatal deaths was 50.4%, 50.7% and 25.8% respectively. Mothers in the other late perinatal deaths were healthy. Maternal hypertension and obstetric haemorrhage were more likely in stillbirths (p = <0.01 for both conditions), whereas ENNDs were more likely to have a healthy mother (p < 0.01). The main causes of neonatal death were related to immaturity (48.7%) and hypoxia (40.6%). 173 (25.2%) of all late perinatal deaths had a birth weight less than the 10 th centile for gestational age. Conclusion: A significant proportion of women have no recognisable obstetric or medical condition at the time of a late perinatal death; we may be limited in our ability to predict poor perinatal outcome if emphasis is put on detecting maternal complications prior to a perinatal death. Intrapartum care and hypertensive disease remain high priority areas for addressing perinatal mortality. Consideration needs to be given to novel ways of detecting growth restriction in a LMIC setting.

What is the impact of multi-professional emergency obstetric and neonatal care training?

Abstract: This paper reviews evidence regarding change in health-care provider behaviour and maternal and neonatal outcomes as a result of emergency obstetric and neonatal care (EmONC) training A refined version of the Kirkpatrick classification for programme evaluation was used to focus on change in efficiency and impact of training (levels 3 and 4) Twenty-three studies were reviewed – five randomised controlled trials, two quasi-experimental studies and 16 before-and-after observational studies Training programmes had all been developed in high-income countries and adapted for use in low- and middle-income countries Nine studies reported on behaviour change and 13 on process and patient outcomes Most showed positive results Every maternity unit should provide EmONC teamwork training, mandatory for all health-care providers The challenges are as follows: scaling up such training to all institutions, sustaining regular in-service training, integrating training into institutional and health-system patient safety initiatives and ‘thinking out of the box' in evaluation research

Triple return on investment: the cost and impact of 13 interventions that could prevent stillbirths and save the lives of mothers and babies in South Africa

Abstract: Background: The time of labor, birth and the first days of life are the most vulnerable period for mothers and children. Despite significant global advocacy, there is insufficient understanding of the investment required to save additional lives. In particular, stillbirths have been neglected. Over 20 000 stillbirths are recorded annually in South Africa, many of which could be averted. This analysis examines available South Africa specific stillbirth data and evaluates the impact and cost-effectiveness of 13 interventions acknowledged to prevent stillbirths and maternal and newborn mortality. Methods: Multiple data sources were reviewed to evaluate changes in stillbirth rates since 2000. The intervention analysis used the Lives Saved tool (LiST) and the Family Planning module (FamPlan) in Spectrum. LiST was used to determine the number of stillbirths and maternal and neonatal deaths that could be averted by scaling up the interventions to full coverage (99%) in 2030. The impact of family planning was assessed by increasing FamPlan’s default 70% coverage of modern contraception to 75% and 80% coverage. Total and incremental costs were determined in the LiST costing module. Cost-effectiveness measured incremental cost effectiveness ratios per potential life years gained. Results: Significant variability exists in national stillbirth data. Using the international stillbirth definition, the SBR was 17.6 per 1 000 births in 2013. Full coverage of the 13 interventions in 2030 could reduce the SBR by 30% to 12.4 per 1 000 births, leading to an MMR of 132 per 100 000 and an NMR of 7 per 1 000 live births. Increased family planning coverage reduces the number of deaths significantly. The full intervention package, with 80% family planning coverage in 2030, would require US$420 million (US$7.8 per capita) annually, which is less than baseline costs of US$550 million (US$10.2 per capita). All interventions were highly cost-effective. Conclusion: This is the first analysis in South Africa to assess the impact of scaling up interventions to avert stillbirths. Improved coverage of 13 interventions that are already recommended could significantly impact the rates of stillbirth and maternal and neonatal mortality. Family planning should also be prioritized to reduce mortality and overall costs.

Basic and comprehensive emergency obstetric and neonatal care in 12 South African health districts

Abstract: Aim. To assess the functionality of healthcare facilities with respect to providing the signal functions of basic and comprehensive emergency obstetric care in 12 districts. Setting. Twelve districts were selected from the 52 districts in South Africa, based on the number of maternal deaths, the institutional maternal mortality ratio and the stillbirth rate for the district. Methods. All community health centres (CHCs) and district, regional and tertiary hospitals were visited and detailed information was obtained on the ability of the facility to perform the basic (BEmONC) and comprehensive (CEmONC) emergency obstetric and neonatal care signal functions. Results. Fifty-three CHCs, 63 district hospitals (DHs), 13 regional hospitals and 4 tertiary hospitals were assessed. None of the CHCs could perform all seven BEmONC signal functions; the majority could not give parenteral antibiotics (68%), perform manual removal of the placenta (58%), do an assisted delivery (98%) or perform manual vacuum aspiration of the uterus in a woman with an uncomplicated incomplete miscarriage (96%). Seventeen per cent of CHCs could not bag-and-mask ventilate a neonate. Less than half (48%) of the DHs could perform all nine CEmONC signal functions (81% could perform eight of the nine functions), 24% could not perform caesarean sections, and 30% could not perform assisted deliveries. Conclusions. The ability of the CHCs and district hospitals to perform the signal functions (lifesaving services) of basic and comprehensive emergency obstetric care was poor in many of the districts studied. This implies that safe maternity care was not consistently available at many facilities conducting births.

Quality-of-care audits and perinatal mortality in South Africa

Abstract: Problem Suboptimal care contributes to perinatal mortality rates. Quality-of-care audits can be used to identify and change suboptimal care, but it is not known if such audits have reduced perinatal mortality in South Africa.Approach We investigated perinatal mortality trends in health facilities that had completed at least five years of quality-of-care audits. In a subset of facilities that began audits from 2006, we analysed modifiable factors that may have contributed to perinatal deaths.Local setting Since the 1990s, the perinatal problem identification programme has performed quality-of-care audits in South Africa to record perinatal deaths, identify modifiable factors and motivate change.Relevant changes Five years of continuous audits were available for 163 facilities. Perinatal mortality rates decreased in 48 facilities (29%) and increased in 52 (32%). Among the subset of facilities that began audits in 2006, there was a decrease in perinatal mortality of 30% (16/54) but an increase in 35% (19/54). Facilities with increasing perinatal mortality were more likely to identify the following contributing factors: patient delay in seeking help when a baby was ill (odds ratio, OR: 4.67; 95% confidence interval, CI: 1.99-10.97); lack of use of antenatal steroids (OR: 9.57; 95% CI: 2.97-30.81); lack of nursing personnel (OR: 2.67; 95% CI: 1.34-5.33); fetal distress not detected antepartum when the fetus is monitored (OR: 2.92; 95% CI: 1.47-5.8) and poor progress in labour with incorrect interpretation of the partogram (OR: 2.77; 95% CI: 1.43-5.34).Lessons learnt Quality-of-care audits were not shown to improve perinatal mortality in this study.

Maternal near miss and maternal death in the Pretoria Academic Complex, South Africa: A population-based study.

Abstract: Background. In order to reduce maternal mortality in South Africa (SA), it is important to understand the process of obstetric care, identify weaknesses within the system, and implement interventions for improving care. Objective. To determine the spectrum of maternal morbidity and mortality in the Pretoria Academic Complex (PAC), SA. Methods. A descriptive population-based study that included all women delivering in the PAC. The World Health Organization definition, criteria and indicators of near miss and maternal death were used to identify women with severe complications in pregnancy. Results. Between 1 August 2013 and 31 July 2014, there were 26 614 deliveries in the PAC. The institutional maternal mortality ratio was 71.4/100 000 live births. The HIV infection rate was 19.9%, and 2.7% of women had unknown HIV status. Of the women, 1 120 (4.2%) developed potentially life-threatening conditions and 136 (0.5%) life-threatening conditions. The mortality index was 14.0% overall, 30.0% for non-pregnancy-related infections, 2.0% for obstetric haemorrhage and 13.6% for hypertension. Of the women with life-threatening conditions, 39.3% were referred from the primary level of care. Vascular, uterine and coagulation dysfunctions were the most frequent organ dysfunctions in women with life-threatening conditions. The perinatal mortality rate was 26.9/1 000 births overall, 23.1/1 000 for women with non-life-threatening conditions, and 198.0/1 000 for women with life-threatening conditions. Conclusion. About one in 20 pregnant women in the PAC had a potentially life-threatening condition; 39.3% of women presented to a primary level facility as an acute emergency and had to be transferred for tertiary care. All healthcare professionals involved in maternity care must have knowledge and skills that equip them to manage obstetric emergencies. Review of the basic antenatal care protocol may be necessary.

What is needed for taking emergency obstetric and neonatal programmes to scale

Abstract: Scaling up an emergency obstetric and neonatal care (EmONC) programme entails reaching a larger number of people in a potentially broader geographical area. Multiple strategies requiring simultaneous attention should be deployed. This paper provides a framework for understanding the implementation, scale-up and sustainability of such programmes. We reviewed the existing literature and drew on our experience in scaling up the Essential Steps in the Management of Obstetric Emergencies (ESMOE) programme in South Africa. We explore the non-linear change process and conditions to be met for taking an existing EmONC programme to scale. Important concepts cutting across all components of a programme are equity, quality and leadership. Conditions to be met include appropriate awareness across the board and a policy environment that leads to the following: commitment, health systems-strengthening actions, allocation of resources (human, financial and capital/material), dissemination and training, supportive supervision and monitoring and evaluation.

Antenatal screening for hepatitis B virus in HIV-infected and uninfected pregnant women in the Tshwane district of South Africa.

Abstract: Background. Despite enormous strides in preventing hepatitis B virus (HBV) infection, perinatal transmission still contributes significantly to HBV epidemiology worldwide; this could account for approximately 50% of chronically infected individuals. Objective. To assess the need for HBV screening in antenatal clinics in the HIV/AIDS era. Methods. This was a retrospective study conducted at the antenatal clinic of 1 Military Hospital, Tshwane, South Africa. Laboratory data for HBV, HIV and CD4 count were obtained and analysed for the period January 2008 ­ December 2013. Results. A total of 2 513 patients’ results were retrieved and 2 368 patients were enrolled as both their HBV and HIV serology results were available. The mean age of participants was 29 years (range 14 ­ 46). HIV prevalence in this study was 20.5% (95% confidence interval (CI) 0.189 ­ 0.222). The median CD4 count in HIV­infected patients was 522 cells/μL (interquartile range 370 ­ 711). There was an overall HBV prevalence of 0.8% (95% CI 0.005 ­ 0.011). The hepatitis B surface antigen (HBsAg) prevalence was significantly higher (2.1%) among HIV co­infected compared with HIV­uninfected patients (0.4%) (p=0.0001). Hepatitis e antigen (HBeAg) positivity was 30% in the HIV co­infected compared with 37.6% in the HIV­uninfected individuals (p=0.7400). Conclusion. This study showed a significantly higher HBV prevalence in HIV­infected compared with HIV­uninfected patients. The comparable HBeAg prevalence between the two groups indicates that both were at an increased risk of vertical transmission, therefore demonstrating a need for antenatal screening for HBV. Since antenatal screening is often not affordable in low­income countries, administration of HBV vaccine at birth is needed for prevention of vertical transmission.

Safety versus accessibility in maternal and perinatal care

Abstract: This article adds to the debate on appropriate staffing in maternity units. My starting point for assessing staffing norms is the staff required to provide a safe maternity unit. A survey in 12 districts showed that their health facilities were not adequately prepared to perform all the essential emergency services required. Lack of staff was often cited as a reason. To test this notion, two norms (World Health Organization (WHO) and Greenfield) giving the minimum staff required for the provision of safe maternity services were applied to the 12 districts. Assuming the appropriate equipment is available and the facility is open 24 hours a day 7 days a week, at a minimum there need to be ten professional nurses with midwifery/advanced midwives to ensure safety for mother and baby in every maternity unit. The norms indicate that the units should do a minimum of 500-1,200 deliveries per year to be cost-effective. All 12 districts had sufficient staff according to the WHO. When the numbers of facilities with maternity units were compared with Council for Scientific and Industrial Research and WHO norms for number of health facilities per population, a large excess of facilities was found. Per district there were sufficient personnel to perform the number of deliveries for that district using the WHO or Greenfield formulas, but per site there were insufficient personnel. In my view there are sufficient personnel to provide safe maternity services, but too many units are performing deliveries, leading to dilution of staff and unsafe services. A realignment of maternity units must be undertaken to provide safe services, even at the expense of accessibility.

Hyperferritinemia and markers of inflammation and oxidative stress in the cord blood of HIV‐exposed, uninfected (HEU) infants

Abstract: Objectives The purpose of this study was to evaluate markers of iron status and inflammation/oxidative stress in maternal and cord blood (CB) of HIV-infected and HIV-uninfected women as potential mechanisms for poor outcomes among HIV-exposed, uninfected (HEU) infants. Methods Maternal venous blood and CB specimens were obtained from 87 pregnant women (45 HIV-infected and 42 HIV-uninfected) enrolled at Kalafong Hospital, Pretoria, South Africa. Iron status [serum iron, ferritin and transferrin concentrations, transferrin saturation, soluble transferrin receptor (sTfR) concentration and the sTfR/log ferritin (sTfR/F) index], antenatal exposure to inflammation (CB C-reactive protein and interleukin-6 concentrations and haptoglobin switch-on status) and oxidative stress [total radical trapping ability of CB plasma (TRAP) and chronic oxidative stress (soluble receptor of advanced glycation end-products (sRAGE) concentration] were assessed in laboratory studies. Results There were no differences between the HIV-infected and HIV-uninfected groups in maternal haematological and iron indices, except that HIV-infected mothers had decreased white blood cell counts (P = 0.048) and increased serum ferritin concentrations (P = 0.032). Ferritin levels were significantly higher in CB than in maternal blood (P < 0.001) in both groups and further elevated in the CB of HEU infants (P = 0.044). There was also an inverse relationship between CB sTfR/F index and sRAGE (r = −0.43; P = 0.003) in the HIV-infected but not in the HIV-uninfected group. Conclusions Our study showed for the first time that ferritin was significantly elevated in CB of HEU infants. The inverse relationship between sTfR/F index and sRAGE in CB suggests that chronic oxidative stress or RAGE axis activation in HIV-infected mothers may play a role in modulating ferritin levels.
