In a systematic review of the literature, Julia Hussein and colleagues seek to determine the effect of referral interventions that enable emergency access to health facilities for pregnant women living in developing countries.

BackgroundLittle is known about the burden of diabetes mellitus (DM) in pregnancy in low- and middle-income countries despite high prevalence and mortality rates being observed in these countries.ObjectiveTo investigate the prevalence and geographical patterns of DM in pregnancy up to 1 year post-delivery in low- and middle-income countries.Search strategyMedline, Embase, Cochrane (Central), Cinahl and CAB databases were searched with no date restrictions.Selection criteriaArticles assessing the prevalence of gestational diabetes mellitus (GDM), and types 1 and 2 DM were sought.Data collection and analysisArticles were independently screened by at least two reviewers. Forest plots were used to present prevalence rates and linear trends calculated by linear regression where appropriate.Main resultsA total of 45 articles were included. The prevalence of GDM varied. Diagnosis was made by the American Diabetes Association criteria (1.50–15.5%), the Australian Diabetes in Pregnancy Society criteria (20.8%), the Diabetes in Pregnancy Study Group India criteria (13.4%), the European Association for the Study of Diabetes criteria (1.6%), the International Association of Diabetes and Pregnancy Study Groups criteria (8.9–20.4%), the National Diabetes Data Group criteria (0.56–6.30%) and the World Health Organization criteria (0.4–24.3%). Vietnam, India and Cuba had the highest prevalence rates. Types 1 and 2 DM were less often reported. Reports of maternal mortality due to DM were not found. No geographical patterns of the prevalence of GDM could be confirmed but data from Africa is particularly limited.ConclusionExisting published data are insufficient to build a clear picture of the burden and distribution of DM in pregnancy in low- and middle-income countries. Consensus on a common diagnostic criterion for GDM is needed. Type 1 and 2 DM in pregnancy and postpartum DM are other neglected areas.

BackgroundMaternal death reviews and obstetric audits identify causes and circumstances related to occurrence of a maternal death or serious complication and inform improvements in quality of care. Given Nigeria’s high maternal mortality, the lessons learned from past experiences can provide a good evidence base for informed decision making. We aimed to synthesise findings from maternal death reviews and other obstetric audits conducted in Nigeria through a systematic review, seeking to identify common barriers and enabling factors related to the provision of emergency obstetric care.MethodsWe searched for maternal death reviews and obstetric care audits reported in the published literature from 2000–2014. A ‘best-fit’ framework approach was used to extract data using a structured data extraction form. The articles that met the inclusion criteria were assessed using a nine point quality score.ResultsOf the 1,841 abstracts and titles at initial screening, 329 full text articles were reviewed and 43 papers fulfilled the inclusion criteria. Four types of barriers were reported related to: transport and referral; health workers; availability of services; and organisational factors. Three elements stand out in Nigeria as contributing to maternal mortality: delays in Caesarean section, unavailability of magnesium sulphate and lack of safe blood transfusion services.ConclusionsObstetric care reviews and audits are useful activities to undertake and should be promoted by improving the processes used to conduct them, as well as extending their implementation to rural and basic level health facilities and to the community. Urgent areas for quality improvement in obstetric care, even in tertiary and teaching hospitals should focus on organisational factors to reduce delays in conducting Caesarean section and making blood and magnesium sulphate available for all who need these interventions.

BackgroundMaternal mortality remains a major international health problem in low- and middle-income countries (LMIC), and most could have been prevented by quality improvement interventions already demonstrated to be effective, such as clinical guideline implementation strategies. The aim of this systematic review was to synthesise qualitative evidence on guideline implementation strategies to improve obstetric care practice in LMIC in order to identify barriers and enablers to their successful implementation.MethodsWe searched MEDLINE and CINAHL databases for articles reporting research findings on barriers and enablers to guideline implementation strategies in obstetric care practice in LMIC. We conducted a “best fit” framework synthesis of the included studies. We used an organisational “stages of change” model as our a priori framework for the synthesis.ResultsNine studies were included: all were based in Sub-Saharan Africa and in hospital health care facilities. The majority of studies (seven) evaluated one particular guideline implementation strategy: clinical audit and feedback (both criterion-based audit and maternal death reviews), and a minority (two) evaluated educational interventions. A range of barriers and enablers to successful guideline implementation was identified. A key finding of the framework synthesis was that “high” and “low” intrinsic health care professional motivation are overall enablers and barriers, respectively, of successful guideline implementation. We developed a modified “stages of change” model to take account of these findings.ConclusionWe have identified a number of quality improvement processes that are amenable to change at limited or no additional cost, although some identified barriers may be difficult to address without increased resources. We note the pathways to implementation may be complex and require further research to develop our understanding of individual and organisational behaviours and motivation in LMIC settings.Trial registrationPROSPERO CRD42015016062 Electronic supplementary materialThe online version of this article (doi:10.1186/s13012-016-0508-1) contains supplementary material, which is available to authorized users.

The high incidence of some complications of GDM is a concern and may indicate poorer care for women with GDM in low-resource settings. The wide IQRs found indicate uncertainty about the burden of GDM in these settings.
