Tranexamic Acid for Postpartum Hemorrhage Treatment in Low-Resource Settings: A Rapid Scoping Review.

Tranexamic acid (TXA) effectively reduces bleeding in women with postpartum hemorrhage (PPH) in hospital settings. To guide policies and practices, this rapid scoping review undertaken by two reviewers aimed to examine how TXA is utilized in lower-level maternity care settings in low-resource settings. Articles were searched in EMBASE, MEDLINE, Emcare, the Maternity and Infant Care Database, the Joanna Briggs Institute Evidence-Based Practice Database, and the Cochrane Library from January 2011 to September 2021. We included non-randomized and randomized research looking at the feasibility, acceptability, and health system implications in low- and lower-middle-income countries. Relevant information was retrieved using pre-tested forms. Findings were descriptively synthesized. Out of 129 identified citations, 23 records were eligible for inclusion, including 20 TXA effectiveness studies, two economic evaluations, and one mortality modeling. Except for the latter, all the studies were conducted in lower-middle-income countries and most occurred in tertiary referral hospitals. When compared to placebo or other medications, TXA was found effective in both treating and preventing PPH during vaginal and cesarean delivery. If made available in home and clinic settings, it can reduce PPH-related mortality. TXA could be cost-effective when used with non-surgical interventions to treat refractory PPH. Capacity building of service providers appears to need time-intensive training and supportive monitoring. No studies were exploring TXA acceptability from the standpoint of providers, as well as the implications for health governance and information systems. There is a scarcity of information on how to prepare the health system and services to incorporate TXA in lower-level maternity care facilities in low-resource settings. Implementation research is critically needed to assist practitioners and decision-makers in establishing a TXA-inclusive PPH treatment package to reduce PPH-related death and disability.

Implementing Heat-Stable Carbetocin for Postpartum Haemorrhage Prevention in Low-Resource Settings: A Rapid Scoping Review.

Heat-stable carbetocin (HSC), a long-acting oxytocin analogue that does not require cold-chain transportation and storage, is effective in preventing postpartum haemorrhage (PPH) in vaginal and caesarean deliveries in tertiary-care settings. We aimed to identify literature documenting how it is implemented in resource-limited and lower-level maternity care settings to inform policies and practices that enable its introduction in these contexts. A rapid scoping review was conducted with an 8-week timeframe by two reviewers. MEDLINE, EMBASE, Emcare, the Joanna Briggs Institute Evidence-Based Practice Database, the Maternity and Infant Care Database, and the Cochrane Library were searched for publications in English, French, and Spanish from January 2011 to September 2021. Randomized and non-randomized studies examining the feasibility, acceptability, and health system considerations in low-income and lower-middle-income countries were included. Relevant data were extracted using pretested forms, and results were synthesized descriptively. The search identified 62 citations, of which 12 met the eligibility criteria. The review did not retrieve studies focusing on acceptability and health system considerations to inform HSC implementation in low-resource settings. There were no studies located in rural or lower-level maternity settings. Two economic evaluations concluded that HSC is not feasible in terms of cost-effectiveness in lower-middle-income economies with private sector pricing, and a third one found superior care costs in births with PPH than without. The other nine studies focused on demonstrating HSC effectiveness for PPH prevention in tertiary hospital settings. There is a lack of evidence on the feasibility (beyond cost-effectiveness), acceptability, and health system considerations related to implementing HSC in resource-constrained and lower-level maternity facilities. Further implementation research is needed to help decision-makers and practitioners offer an HSC-inclusive intervention package to prevent excessive bleeding among pregnant women living in settings where oxytocin is not available or of dubious quality.

Promoting adolescent health through integrated human papillomavirus vaccination programs: The experience of Togo.

The introduction of the Human papillomavirus (HPV) vaccine has shown potential to not only prevent cervical cancer but also drive adolescents' access to other health care services, even in low-income countries. Few studies have been conducted to date to identify best practices and estimate the acceptance, operational challenges and benefits of including broader adolescent health interventions into immunization efforts, knowledge which is essential to supporting widespread integration. In this paper we review the efforts undertaken by the government of Togo to integrate adolescent health programming with the HPV vaccination roll out. With the support of partners (GAVI, WHO, UNFPA and UNICEF), the country successfully completed, in 2017, two years of an HPV vaccine demonstration project, which entailed vaccinating 10-year-old girls against HPV in two selected districts of the country and integrating a health education component focused on puberty education / menstrual hygiene and hand washing practice. Our study is a post-implementation program evaluation, using mixed methods to assess key questions of feasibility and acceptability of an integrated adolescent package of care. It showed that the HPV vaccination in conjunction with the health education sessions was well received by the majority of health care providers, teachers and parents. Our study confirmed that in Togo it proved feasible to combine education and HPV vaccination in school-based service delivery. However, more operational research is neded to understand how to increase the impact and sustainability of the co-delivery of interventions. We did not analyze the health impact and cost implications of the intervention, which will be an important consideration for scaling up such integration efforts alongside routine immunization.

Categorising interventions to levels of inpatient care for small and sick newborns: Findings from a global survey.

BACKGROUND: In 2017, 2.5 million newborns died, mainly from prematurity, infections, and intrapartum events. Preventing these deaths requires health systems to provide routine and emergency care at birth, and quality inpatient care for small and sick newborns. Defined levels of emergency obstetric care (EmOC) and standardised measurement of "signal functions" has improved tracking of maternal care in low- and middle-income countries (LMICs). Levels of newborn care, particularly for small and sick newborns, and associated signal functions are still not consistently defined or tracked. METHODS: Between November 2016-November 2017, we conducted an online survey of professionals working in maternal and newborn health. We asked respondents to categorise 18 clinical care interventions that could act as potential signal functions for small and sick newborns to 3 levels of care they thought were appropriate for health systems in LMICs to provide: "routine care at birth", "special care" and "intensive care". We calculated the percentage of respondents that classified each intervention at each level of care and stratified responses to look at variation by respondent characteristics. RESULTS: Six interventions were classified to specific levels by more than 50% of respondents as "routine care at birth," three interventions as "special care" and one as "intensive care". Eight interventions were borderline between these care levels. Responses were more consistent for interventions with relevant WHO clinical care guidelines while more variation in respondents' classification was observed in complex interventions that lack standards or guidelines. Respondents with experience in lower-income settings were more likely to assign a higher level of care for more complex interventions. CONCLUSIONS: Results were consistent with known challenges of scaling up inpatient care in lower-income settings and underline the importance of comprehensive guidelines and standards for inpatient care. Further work is needed to develop a shortlist of newborn signal functions aligned with emergency obstetric care levels to track universal health coverage for mothers and their newborns.

Monitoring and evaluation of disaster response efforts undertaken by local health departments: a rapid realist review.

BACKGROUND: Local health departments are often at the forefront of a disaster response, attending to the immediate trauma inflicted by the disaster and also the long term health consequences. As the frequency and severity of disasters are projected to rise, monitoring and evaluation (M&E) efforts are critical to help local health departments consolidate past experiences and improve future response efforts. Local health departments often conduct M&E work post disaster, however, many of these efforts fail to improve response procedures. METHODS: We undertook a rapid realist review (RRR) to examine why M&E efforts undertaken by local health departments do not always result in improved disaster response efforts. We aimed to complement existing frameworks by focusing on the most basic and pragmatic steps of a M&E cycle targeted towards continuous system improvements. For these purposes, we developed a theoretical framework that draws on the quality improvement literature to 'frame' the steps in the M&E cycle. This framework encompassed a M&E cycle involving three stages (i.e., document and assess, disseminate and implement) that must be sequentially completed to learn from past experiences and improve future disaster response efforts. We used this framework to guide our examination of the literature and to identify any context-mechanism-outcome (CMO) configurations which describe how M&E may be constrained or enabled at each stage of the M&E cycle. RESULTS: This RRR found a number of explanatory CMO configurations that provide valuable insights into some of the considerations that should be made when using M&E to improve future disaster response efforts. Firstly, to support the accurate documentation and assessment of a disaster response, local health departments should consider how they can: establish a culture of learning within health departments; use embedded training methods; or facilitate external partnerships. Secondly, to enhance the widespread dissemination of lessons learned and facilitate inter-agency learning, evaluation reports should use standardised formats and terminology. Lastly, to increase commitment to improvement processes, local health department leaders should possess positive leadership attributes and encourage shared decision making. CONCLUSION: This study is among the first to conduct a synthesis of the CMO configurations which facilitate or hinder M&E efforts aimed at improving future disaster responses. It makes a significant contribution to the disaster literature and provides an evidence base that can be used to provide pragmatic guidance for improving M&E efforts of local health departments.

The Impact of Healthcare Insurance on the Utilisation of Facility-Based Delivery for Childbirth in the Philippines.

OBJECTIVES: In recent years, the government of the Philippines embarked upon an ambitious Universal Health Care program, underpinned by the rapid scale-up of subsidized insurance coverage for poor and vulnerable populations. With a view of reducing the stubbornly high maternal mortality rates in the country, the program has a strong focus on maternal health services and is supported by a national policy of universal facility-based delivery (FBD). In this study, we examine the impact that recent reforms expanding health insurance coverage have had on FBD. RESULTS: Data from the most recent Philippines 2013 Demographic Health Survey was employed. This study applies quasi-experimental methods using propensity scores along with alternative matching techniques and weighted regression to control for self-selection and investigate the impact of health insurance on the utilization of FBD. FINDINGS: Our findings reveal that the likelihood of FBD for women who are insured is between 5 to 10 percent higher than for those without insurance. The impact of health insurance is more pronounced amongst rural and poor women for whom insurance leads to a 9 to 11 per cent higher likelihood of FBD. CONCLUSIONS: We conclude that increasing health insurance coverage is likely to be an effective approach to increase women's access to FBD. Our findings suggest that when such coverage is subsidized, as it is the case in the Philippines, women from poor and rural populations are likely to benefit the most.

Utilisation of health services and the poor: deconstructing wealth-based differences in facility-based delivery in the Philippines.

BACKGROUND: Despite achieving some success, wealth-related disparities in the utilisation of maternal and child health services persist in the Philippines. The aim of this study is to decompose the principal factors driving the wealth-based utilisation gap. METHODS: Using national representative data from the 2013 Philippines Demographic and Health Survey, we examine the extent overall differences in the utilisation of maternal health services can be explained by observable factors. We apply nonlinear Blinder-Oaxaca-type decomposition methods to quantify the effect of differences in measurable characteristics on the wealth-based coverage gap in facility-based delivery. RESULTS: The mean coverage of facility-based deliveries was respectively 41.1 % and 74.6 % for poor and non-poor households. Between 67 and 69 % of the wealth-based coverage gap was explained by differences in observed characteristics. After controlling for factors characterising the socioeconomic status of the household (i.e. the mothers' and her partners' education and occupation), the birth order of the child was the major factor contributing to the disparity. Mothers' religion and the subjective distance to the health facility were also noteworthy. CONCLUSIONS: This study has found moderate wealth-based disparities in the utilisation of institutional delivery in the Philippines. The results confirm the importance of recent efforts made by the Philippine government to implement equitable, pro-poor focused health programs in the most deprived geographic areas of the country. The importance of addressing the social determinants of health, particularly education, as well as developing and implementing effective strategies to encourage institutional delivery for higher order births, should be prioritised.

Overcoming Stagnation in the Levels and Distribution of Child Mortality: The Case of the Philippines.

BACKGROUND: Health-related within-country inequalities continue to be a matter of great interest and concern to both policy makers and researchers. This study aims to assess the level and the distribution of child mortality outcomes in the Philippines across geographical and socioeconomic indicators. METHODOLOGY: Data on 159,130 children ever borne were analysed from five waves of the Philippine Demographic and Health Survey. Direct estimation was used to construct under-five and neonatal mortality rates for the period 1980-2013. Rate differences and ratios, and where possible, slope and relative indices of inequality were calculated to measure disparities on absolute and relative scales. Stratification was undertaken by levels of rural/urban location, island groups and household wealth. FINDINGS: National under-five and neonatal mortality rates have shown considerable albeit differential reductions since 1980. Recently released data suggests that neonatal mortality has declined following a period of stagnation. Declines in under-five mortality have been accompanied by decreases in wealth and geography-related absolute inequalities. However, relative inequalities for the same markers have remained stable over time. For neonates, mixed evidence suggests that absolute and relative inequalities have remained stable or may have risen. CONCLUSION: In addition to continued reductions in under-five mortality, new data suggests that the Philippines have achieved success in addressing the commonly observed stagnated trend in neonatal mortality. This success has been driven by economic improvement since 2006 as well as efforts to implement a nationwide universal health care campaign. Yet, such patterns, nonetheless, accorded with persistent inequalities, particularly on a relative scale. A continued focus on addressing universal coverage, the influence of decentralisation and armed conflict, and issues along the continuum of care is advocated.

Cord blood chemerin: differential effects of gestational diabetes mellitus and maternal obesity.

OBJECTIVE: Chemerin is a novel adipokine implicated in inflammation and obesity. We hypothesized that foetal chemerin would be elevated in gestational diabetes mellitus (GDM) and correlate with foetal and maternal adiposity. DESIGN: Observational, longitudinal study. SUBJECTS AND MEASUREMENTS: Foetal chemerin was measured separately in arterial and venous cord blood of 30 infants born to mothers with (n = 15) and without GDM (n = 15), in their mothers in early third trimester and at delivery and in amniotic fluid (week 32) of women with GDM. Expression of chemerin and its receptor in human foetal tissues commercially available and in placental cells was measured by quantitative PCR. Associations between foetal and maternal anthropometric and metabolic variables were assessed in multivariate regression models. RESULTS: In GDM, foetal arterial but not venous cord blood chemerin levels were elevated by about 60% (P < 0·05). Venous cord blood chemerin was higher in infants of obese women (P < 0·01). In multivariate analyses, neither amniotic fluid nor cord blood chemerin levels correlated with birth weight or ponderal index. Both arterial and venous chemerin levels were related to maternal chemerin at birth, and arterial chemerin was associated with GDM status in addition. Maternal levels were unaltered in GDM, but higher in maternal obesity. Foetal liver produces fourfold more chemerin mRNA than other foetal tissues, whereas its receptor prevails in spleen. CONCLUSIONS: Based on multivariate analyses, foetal growth appears unrelated to foetal chemerin. Maternal obesity and GDM have differential effects on foetal chemerin levels. Site of major production (liver) and action (spleen) differ in human foetal tissues.

Quality of caesarean delivery services and documentation in first-line referral facilities in Afghanistan: a chart review.

BACKGROUND: Increasing appropriate use and documentation of caesarean section (CS) has the potential to decrease maternal and perinatal mortality in settings with low CS rates. We analyzed data collected as part of a comprehensive needs assessment of emergency obstetric and newborn care (EmONC) facilities in Afghanistan to gain a greater understanding of the clinical indications, timeliness, and outcomes of CS deliveries. METHODS: Records were reviewed at 78 government health facilities expected to function as EmONC providers that were located in secure areas of the country. Information was collected on the three most recent CS deliveries in the preceding 12 months at facilities with at least one CS delivery in the preceding three months. After excluding 16 facilities with no recent CS deliveries, the sample includes 173 CS deliveries at 62 facilities. RESULTS: No CS deliveries were performed in the previous three months at 21% of facilities surveyed; all of these were lower-level facilities. Most CS deliveries (88%) were classified as emergencies, and only 12% were referrals from another facility. General anesthesia was used in 62% of cases, and spinal or epidural anesthesia in 34%. Only 28% of cases were managed with a partograph. Surgery began less than one hour after the decision for a CS delivery in just 30% of emergency cases. Among the 173 cases, 27 maternal deaths, 28 stillbirths, and 3 early neonatal deaths were documented. In cases of maternal and fetal death, the most common indications for CS delivery were placenta praevia or abruption and malpresentation. In 62% of maternal deaths, the fetus was stillborn or died shortly after birth. In 48% of stillbirths, the fetus had a normal heart rate at the last check. Information on partograph use was missing in 38% of cases, information on parity missing in 23% of cases and indications for cesareans missing in 9%. CONCLUSIONS: Timely referral within and to EmONC facilities would decrease the proportion of CS deliveries that develop to emergency status. While the substantial mortality associated with CS in Afghanistan may be partly due to women coming late for obstetric care, efforts to increase the availability and utilization of CS must also focus on improving the quality of care to reduce mortality. Key goals should be encouraging use of partographs and improving decision-making and documentation around CS deliveries.
