Labor augmentation with oxytocin in low- and lower-middle-income countries: a systematic review and meta-analysis.

OBJECTIVE: Despite its worldwide use, reviews of oxytocin for labor augmentation include mainly studies from high-income countries. Meanwhile, oxytocin is a potentially harmful medication and risks may be higher in low-resource settings. We conducted a systematic review and meta-analysis of practices, benefits, and risks of oxytocin for labor augmentation in low- and lower-middle-income countries. DATA SOURCES: PubMed, Embase, PsycINFO, Index Medicus, Cochrane, and Google Scholar were searched for publications until January 1, 2022. STUDY ELIGIBILITY CRITERIA: All studies evaluating oxytocin augmentation rates were included. To investigate benefits and risks, randomized and quasi-randomized trials comparing oxytocin augmentation with placebo or no oxytocin were included. To explore risks more broadly, cohort and case-control studies were also included. METHODS: Data were extracted and quality-assessed by 2 researchers using a modified Newcastle-Ottawa scale. Generic inverse variance outcome and a random-effects model were used. Adjusted or crude effect measures with 95% confidence intervals were used. RESULTS: In total, 42 studies were included, presenting data from 885 health facilities in 25 low- and lower-middle-income countries (124,643 women). Rates of oxytocin for labor augmentation varied from 0.7% to 97.0%, exceeding 30% in 14 countries. Four studies investigated timing of oxytocin for augmentation and found that 89.5% (2745) of labors augmented with oxytocin did not cross the partograph's action line. Four cohort and 7 case-control studies assessed perinatal outcomes. Meta-analysis revealed that oxytocin was associated with: stillbirth and day-1 neonatal mortality (relative risk, 1.45; 95% confidence interval, 1.02-2.06; N=84,077; 6 studies); low Apgar score (relative risk, 1.54; 95% confidence interval, 1.21-1.96; N=80,157; 4 studies); neonatal resuscitation (relative risk, 2.69; 95% confidence interval, 1.87-3.88; N=86,750; 3 studies); and neonatal encephalopathy (relative risk, 2.90; 95% confidence interval, 1.87-4.49; N=1383; 2 studies). No studies assessed effects on cesarean birth rate and uterine rupture. CONCLUSION: This review discloses a concerning level of oxytocin use, including in labors that often did not fulfill criteria for dystocia. Although this finding is limited by confounding by indication, oxytocin seems associated with increased perinatal risks, which are likely mediated by inadequate fetal monitoring. We call for cautious use on clear indications and robust implementation research to support evidence-based guidelines for labor augmentation, particularly in low-resource settings.

Averting Maternal Death and Disability in an Urban Network of Care in Dar es Salaam, Tanzania: A Descriptive Case Study.

The non-governmental organization Comprehensive Community Based Rehabilitation in Tanzania (CCBRT) developed a multi-facility maternal and neonatal Network of Care (NOC) among 22 government hospitals and catchment facilities operating across Dar es Salaam. While facility delivery rates were above 90% in the Dar es Salaam region, the quality of services was substandard, leading to an excess of preventable maternal and neonatal morbidity and mortality. In partnership with the Dar es Salaam regional health authorities CCBRT developed a plan to improve the quality of service delivery at childbirth by through a system strengthening approach, capacitating lower-level facilities to provide routine care during pregnancy and uncomplicated deliveries, as well as improving care at secondary level referral hospitals and developing an inter-connected strengthened referral system. The Regional-CCBRT partnership implemented interventions across the continuum of care that included clinical training in basic and comprehensive emergency obstetric care, investments in infrastructure, and a rigorous maternal and perinatal death audit and follow-up program. Routine data generated were reflected upon at quarterly quality improvement meetings to follow up on problems identified. The government has initiated the replication of the model. This descriptive case study uses the four domains of the Networks of Care framework to document the wide-ranging efforts made to build and maintain the CCBRT Network of Care in order to solve for specific challenges in maternal and neonatal health service delivery in the urban context of the Dar es Salaam region.

Implementation outcomes of policy and programme innovations to prevent obstetric haemorrhage in low- and middle-income countries: a systematic review.

Globally, obstetric haemorrhage (OH) remains the leading cause of maternal mortality. Much of the associated mortality is ascribed to challenges surrounding deployment of innovations rather than lack of availability. In low- and middle-income countries (LMICs), where the burden is highest, there is a growing interest in implementation research as a means to bridge the 'know-do' gap between proven interventions and their reliable implementation at scale. In this systematic review, we identified and synthesized qualitative and quantitative data across the implementation outcomes of OH prevention innovations in LMICs using a taxonomy developed by Proctor et al. We also identified service outcomes for the included innovations, as well as implementation strategies and implementation facilitators and barriers. Eligible studies were empirical, focused on the implementation of OH prevention programmes or policies and occurred in an LMIC. Eight databases were searched. Two authors independently assessed studies for selection and extracted data; the first author resolved discrepancies. Narrative synthesis was used to analyse and interpret the findings. Studies were predominantly focused in Africa and on primary prevention. Interventions included prophylactic use of uterotonics (n = 7), clinical provider skills training (n = 4) and provision of clinical guidelines (n = 1); some (n = 3) were also part of a multi-component quality improvement bundle. Various barriers were reported, including challenges among intervention beneficiaries, providers and within the health system; however, studies reported the development and testing of practical implementation solutions. These included training and monitoring of implementers, community and stakeholder engagement and guidance by external mentors. Some studies linked successful delivery to implementation outcomes, most commonly adoption and acceptability, but also feasibility, penetration and sustainability. Findings suggest that innovations to prevent OH can be acceptable, appropriate and feasible in LMIC settings; however, more research is needed to better evaluate these and other under-reported implementation outcomes.

Towards equitable surgical systems: development and outcomes of a national surgical, obstetric and anaesthesia plan in Tanzania.

Despite emergency and essential surgery and anaesthesia care being recognised as a part of Universal Health Coverage, 5 billion people worldwide lack access to safe, timely and affordable surgery and anaesthesia care. In Tanzania, 19% of all deaths and 17 % of disability-adjusted life years are attributable to conditions amenable to surgery. It is recommended that countries develop and implement National Surgical, Obstetric and Anesthesia Plans (NSOAPs) to systematically improve quality and access to surgical, obstetric and anaesthesia (SOA) care across six domains of the health system including (1) service delivery, (2) infrastructure, including equipment and supplies, (3) workforce, (4) information management, (5) finance and (6) Governance. This paper describes the NSOAP development, recommendations and lessons learnt from undertaking NSOAP development in Tanzania. The NSOAP development driven by the Ministry of Health Community Development Gender Elderly and Children involved broad consultation with over 200 stakeholders from across government, professional associations, clinicians, ancillary staff, civil society and patient organisations. The NSOAP describes time-bound, costed strategic objectives, outputs, activities and targets to improve each domain of the SOA system. The final NSOAP is ambitious but attainable, reflects on-the-ground priorities, aligns with existing health policy and costs an additional 3% of current healthcare expenditure. Tanzania is the third country to complete such a plan and the first to report on the NSOAP development in such detail. The NSOAP development in Tanzania provides a roadmap for other countries wishing to undertake a similar NSOAP development to strengthen their SOA system.

Newborn screening for sickle cell disease: an innovative pilot program to improve child survival in Dar es Salaam, Tanzania.

BACKGROUND: Sickle cell disease (SCD) is a recognized cause of childhood mortality. Tanzania has the fifth highest incidence of SCD (with an estimated 11 000 SCD annual births) worldwide. Although newborn screening (NBS) for SCD and comprehensive healthcare have been shown to reduce under-5 mortality by up to 94% in high-income countries such as the USA, no country in Africa has maintained NBS for SCD as a national health program. The aims of this program were to establish and evaluate NBS-SCD as a health intervention in Tanzania and to determine the birth prevalence of SCD. METHODS: Muhimbili University of Health and Allied Sciences conducted NBS for SCD from January 2015 to November 2016. Dried blood spot samples were collected and tested for SCD using isoelectric focusing. RESULTS: Screening was conducted on 3981 newborns. Thirty-one (0.8%) babies had SCD, 505 (12.6%) had sickle cell trait and 26 (0.7%) had other hemoglobinopathies. Twenty-eight (90.3%) of the 31 newborns with SCD were enrolled for comprehensive healthcare. CONCLUSIONS: This is the first report on NBS as a health program for SCD in Tanzania. The SCD birth prevalence of 8 per 1000 births is of public health significance. It is therefore important to conduct NBS for SCD with enrollment into a comprehensive care program.

Maternal mortality at Muhimbili National Hospital in Dar-es-Salaam, Tanzania in the year 2011.

BACKGROUND: Improving maternal health is one of the eight millennium development goals adopted at the millennium summit in the year 2000. Within this frame work, the international community is committed to reduce the maternal mortality ratio by 75% between 1990 and 2015. The objective of this study was to determine the maternal mortality ratio, classify causes of maternal deaths and assess substandard care factors at Muhimbili National Hospital (MNH), Dar-es-Salaam in Tanzania. METHODS: A retrospective review of all maternal death records of cases that occurred from 1st January to 31st December 2011 was done. RESULTS: There were 10,057 live births, 155 maternal deaths and hence MMR of 1,541 per 100,000 live births. Direct causes of maternal deaths were classified in 69.5% of the maternal deaths. Of the direct causes, preeclampsia/eclampsia was the major cause (19.9% of all deaths), followed by post partum haemorrhage (14.9%), abortion complications (9.9%) and sepsis (9.2%). Among the indirect causes anaemia was the leading cause (11.3%) of all deaths, followed by HIV/AIDS (9.9%). Substandard care factors contributing to deaths were identified in 116 (82.3%) of all cases. Among these 28 had patient factors only, 71 medical service factors while 17 had both patient and medical service substandard care factors. The common factors from the woman's side included delay in seeking care (73.3%) and complete lack of antenatal care (11.1%). Of the medical service factors, inadequate (26.1%) or no blood for transfusion (19.3%), delay in receiving treatment (18.3%) and mismanagement (17%) were the common factors. CONCLUSION: There is a high maternal mortality ratio at MNH. Hypertensive disorders of pregnancy, post partum haemorrhage and anaemia are the leading causes of maternal deaths in this institution. Multiple substandard care factors identified both at individual and health care service levels that contributed to maternal deaths. There is a need for increasing efforts in the fight to reduce maternal deaths at the institution. A more pro-active role from the referring facilities in the region is needed.
