Antenatal care services and its implications for vital and health outcomes of children: evidence from 193 surveys in 69 low-income and middle-income countries

OBJECTIVES

Antenatal care (ANC) is an essential part of primary healthcare and its provision has expanded worldwide. There is limited evidence of large-scale cross-country studies on the impact of ANC offered to pregnant women on child health outcomes. We investigate the association of ANC in low-income and middle-income countries with short- and long-term mortality and nutritional child outcomes.

SETTING

We used nationally representative health and welfare data from 193 Demographic and Health Surveys conducted between 1990 and 2013 from 69 low-income and middle-income countries for women of reproductive age (15-49 years), their children and their respective household.

PARTICIPANTS

The analytical sample consisted of 752 635 observations for neonatal mortality, 574 675 observations for infant mortality, 400 426 observations for low birth weight, 501 484 observations for stunting and 512 424 observations for underweight.

MAIN OUTCOMES AND MEASURES

Outcome variables are neonatal and infant mortality, low birth weight, stunting and underweight.

RESULTS

At least one ANC visit was associated with a 1.04% points reduced probability of neonatal mortality and a 1.07% points lower probability of infant mortality. Having at least four ANC visits and having at least once seen a skilled provider reduced the probability by an additional 0.56% and 0.42% points, respectively. At least one ANC visit is associated with a 3.82% points reduced probability of giving birth to a low birth weight baby and a 4.11 and 3.26% points reduced stunting and underweight probability. Having at least four ANC visits and at least once seen a skilled provider reduced the probability by an additional 2.83%, 1.41% and 1.90% points, respectively.

CONCLUSIONS

The currently existing and accessed ANC services in low-income and middle-income countries are directly associated with improved birth outcomes and longer-term reductions of child mortality and malnourishment.

A systematic review on ethical challenges of 'field' research in low-income and middle-income countries: respect, justice and beneficence for research staff?

Introduction

Primary data collection in low-income and middle-income countries (LMICs) is associated with a range of ethical complexities. Considerations on how to adequately ensure the well-being of research staff are largely neglected in contemporary ethics discourse. This systematic review aims to identify the ethical challenges that research staff across different hierarchical levels and scientific disciplines face when conducting research in LMICs.

Methods

We searched 13 electronic databases and handsearched publications in six selected journals as well as the reference lists of all included studies. No restrictions were applied with respect to the publication date, research design, and target population.

Results

23 151 studies were retrieved, 183 of which met our inclusion criteria. We identified nine different types of ethical challenges that research staff may be exposed to during field research, including (1) role conflicts that can emerge from participants’ help requests and the high level of deprivation found in certain study settings, (2) feelings of guilt and (3) detrimental mental health impacts. Further challenges were (4) sexual harassment (5) safety risks and (6) political repression, particularly in postconflict, disaster-ridden or autocratic study contexts. Additionally, studies reported (7) inadequate working conditions and (8) power imbalances within research teams, while (9) ethics boards were found to be ill equipped to anticipate and address emerging risks, thus increasing the ethical liability of researchers.

Conclusion

This review revealed several complex ethical challenges that research staff may face during data collection. In order to achieve the Sustainable Development Goal 8.8 on ‘safe and secure working environments’ and to protect research staff from harm, amendments must urgently be made to current ethical standards.

Public provision of emergency obstetric care: a case study in two districts of Pakistan

OBJECTIVES

Pakistan is one out of five countries where together half of the global neonatal deaths occur. As the provision of services and facilities is one of the key elements vital to reducing this rate as well as the maternal mortality rate, this study investigates the status of the delivery of essential obstetric care provided by the public health sector in two districts in Khyber Pakhtunkhwa in 2015 aiming to highlight areas where critical improvements are needed.

SETTING

We analysed data from a survey of 22 primary and secondary healthcare facilities as well as 85 community midwives (CMWs) in Haripur and Nowshera districts.

PARTICIPANTS

Using a structured questionnaire we evaluated the performance of emergency obstetric care (EmOC) signal functions and patient statistics in public health facilities. Also, 102 CMWs were interviewed about working hours, basic and specialised delivery service provision, referral system and patient statistics.

PRIMARY OUTCOME MEASURES

We investigate the public provision of emergency obstetric care using seven key medical services identified by the United Nations (UN).

RESULTS

Deliveries by public health cadres account for about 30% of the total number of births in these districts. According to the UN benchmark, only a small fraction of basic EmOC (2/18) and half of the comprehensive EmOC (2/4) facilities of the recommended minimum number were available to the population in both districts. Only a minority of health facilities and CMWs carry out several signal functions. Only 8% of the total births in one of the study districts are performed in public EmOC health facilities.

CONCLUSIONS

Both districts show a significant shortage of available public EmOC service provisions. Development priorities need to be realigned to improve the availability, accessibility and quality of EmOC service provisions by the public health sector alongside with existing activities to increase institutional births.

The effect of the WHO Safe Childbirth Checklist on essential delivery practices and birth outcomes: Evidence from a pair-wise matched randomized controlled trial in Pakistan

We study the effect of the Safe Childbirth Checklist (SCC) - a tool developed by the WHO to improve the quality of delivery care - on a range of provider- and patient-level outcomes. We conducted a clustered pair-wise matched randomized controlled trial among 166 health providers in two districts of Pakistan. This included primary and secondary health facilities as well as non-facility based rural health workers. We do not find positive effects on health outcomes, but on the adherence to some essential delivery practices, mostly to those conducted during the patient's admission to the delivery ward. We also find increased rates of referrals to higher-level facilities.

Safeguarding research staff “in the field”: a blind spot in ethics guidelines

Across disciplines there is a large and increasing number of research projects that rely on data collection activities in low- and middle-income countries (LMICs). However, these are accompanied by an extensive range of ethical challenges. While the safeguarding of study participants is the primary aim of existing ethics guidelines, this paper argues that this “do no harm” principle should be extended to include research staff. This study is a comprehensive review of more than 80 existing ethics guidelines and protocols that reveals a lack of safeguarding research staff regarding the ethical challenges faced during data collection activities in LMICs. This is particularly the case when it comes to issues such as power imbalances, political risk, staff’s emotional wellbeing or dealing with feelings of guilt. Lead organizations are called upon to develop guiding principles that encompass the safeguarding of research staff, which are then to be adapted and translated into specific protocols and tools by institutions.

Myocardial injury in patients with acute ischemic stroke detected by cardiovascular magnetic resonance imaging

BACKGROUND

Patients with acute ischemic stroke (AIS) are at high risk of adverse cardiovascular events. Until now, the burden of myocardial injury derived from cardiovascular magnetic resonance imaging (CMR) has not been established in this population.

METHODS

Patients with AIS underwent CMR at 3 Tesla within 120 h after the index stroke as part of a prospective, single-center study. Patients with persistent atrial fibrillation were excluded. Morphology and function of both cardiac chambers and atria were assessed applying SSFP cine. Myocardial tissue differentiation was based on native and contrast-enhanced imaging including late gadolinium enhancement (LGE) after 0.15 mmol/kg gadobutrol for focal fibrosis and parametric T2- and T1-mapping for diffuse findings. To detect myocardial deformation global longitudinal (GLS), circumferential (GCS) and radial (GRS) strain was measured applying feature tracking. Cardiac troponin was measured using a high-sensitivity assay (99th percentile upper reference limit 14 ng/L). T2 mapping values were compared with 20 healthy volunteers.

RESULTS

CMR with contrast media was successfully performed in 92 of 115 patients (mean age 74 years, 40% female, known myocardial infarction 6%). Focal myocardial fibrosis (LGE) was detected in 31 of 92 patients (34%) of whom 23/31 (74%) showed an ischemic pattern. Patients with LGE were more likely to have diabetes, prior myocardial infarction, prior ischemic stroke, and to have elevated troponin levels compared to those without. Presence of LGE was accompanied by diffuse fibrosis (increased T1 native values) even in remote cardiac areas as well as reduced global radial, circumferential and longitudinal strain values. In 14/31 (45%) of all patients with LGE increased T2-mapping values were detectable.

CONCLUSIONS

More than one-third of patients with AIS have evidence of focal myocardial fibrosis on CMR. Nearly half of these changes may have acute or subacute onset. These findings are accompanied by diffuse myocardial changes and reduced myocardial deformation. Further studies, ideally with serial CMR measurements during follow-up, are required to establish the impact of these findings on long-term prognosis after AIS.
