    ABSTRACT: 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. 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. 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. 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). Quality-of-care audits were not shown to improve perinatal mortality in this study.

    ABSTRACT: Over the last few decades, maternal health has been a major focus of the international community and this has resulted in a substantial decrease in maternal mortality globally. Although, compared with maternal illness, medical and surgical emergencies account for far more morbidity and mortality, there has been less focus on global efforts to improve comprehensive emergency systems. The thoughtful and specific application of the concepts used in the effort to decrease maternal mortality could lead to major improvements in global emergency health services. The so-called three-delay model that was developed for maternal mortality can be adapted to emergency service delivery. Adaptation of evaluation frameworks to include emergency sentinel conditions could allow effective monitoring of emergency facilities and further policy development. Future global emergency health efforts may benefit from incorporating strategies for the planning and evaluation of high-impact interventions.

    ABSTRACT: To assess the effect of tobacco smoking on the outcome of tuberculosis treatment in Tbilisi, Georgia. We conducted a prospective cohort study of adults with laboratory-confirmed tuberculosis from May 2011 to November 2013. History of tobacco smoking was collected using a standardized questionnaire adapted from the global adult tobacco survey. We considered tuberculosis therapy to have a poor outcome if participants defaulted, failed treatment or died. We used multivariable regressions to estimate the risk of a poor treatment outcome. Of the 591 tuberculosis patients enrolled, 188 (31.8%) were past smokers and 271 (45.9%) were current smokers. Ninety (33.2%) of the current smokers and 24 (18.2%) of the participants who had never smoked had previously been treated for tuberculosis (P < 0.01). Treatment outcome data were available for 524 of the participants, of whom 128 (24.4%) - including 80 (32.9%) of the 243 current smokers and 21 (17.2%) of the 122 individuals who had never smoked - had a poor treatment outcome. Compared with those who had never smoked, current smokers had an increased risk of poor treatment outcome (adjusted relative risk, aRR: 1.70; 95% confidence interval, CI: 1.00-2.90). Those who had ceased smoking more than two months before enrolment did not have such an increased risk (aRR: 1.01; 95% CI: 0.51-1.99). There is a high prevalence of smoking among patients with tuberculosis in Georgia and smoking increases the risk of a poor treatment outcome.

    ABSTRACT: Visual impairment affects nearly 285 million people worldwide. Although there has been much progress in combating the burden of visual impairment through initiatives such as VISION 2020, barriers to progress, especially in African countries, remain high. The Rwandan Ministry of Health has formed partnerships with several nongovernmental organizations and has worked to integrate their efforts to prevent and treat visual impairment, including presbyopia. Rwanda, an eastern African country of approximately 11 million people. The Rwandan Ministry of Health developed a single national plan that allows key partners in vision care to coordinate more effectively in measuring eye disease, developing eye care infrastructure, building capacity, controlling disease, and delivering and evaluating services. Collaboration between stakeholders under a single national plan has ensured that resources and efforts are complementary, optimizing the ability to provide eye care. Improved access to primary eye care and insurance coverage has increased demand for services at secondary and tertiary levels. A comprehensive strategy that includes prevention as well as a supply chain for glasses and lenses is needed.

    ABSTRACT: To investigate which strategies to increase demand for vaccination are effective in increasing child vaccine coverage in low- and middle-income countries. We searched MEDLINE, EMBASE, Cochrane library, POPLINE, ECONLIT, CINAHL, LILACS, BDSP, Web of Science and Scopus databases for relevant studies, published in English, French, German, Hindi, Portuguese and Spanish up to 25 March 2014. We included studies of interventions intended to increase demand for routine childhood vaccination. Studies were eligible if conducted in low- and middle-income countries and employing a randomized controlled trial, non-randomized controlled trial, controlled before-and-after or interrupted time series design. We estimated risk of bias using Cochrane collaboration guidelines and performed random-effects meta-analysis. We identified 11 studies comprising four randomized controlled trials, six cluster randomized controlled trials and one controlled before-and-after study published in English between 1996 and 2013. Participants were generally parents of young children exposed to an eligible intervention. Six studies demonstrated low risk of bias and five studies had moderate to high risk of bias. We conducted a pooled analysis considering all 11 studies, with data from 11 512 participants. Demand-side interventions were associated with significantly higher receipt of vaccines, relative risk (RR): 1.30, (95% confidence interval, CI: 1.17-1.44). Subgroup analyses also demonstrated significant effects of seven education and knowledge translation studies, RR: 1.40 (95% CI: 1.20-1.63) and of four studies which used incentives, RR: 1.28 (95% CI: 1.12-1.45). Demand-side interventions lead to significant gains in child vaccination coverage in low- and middle-income countries. Educational approaches and use of incentives were both effective strategies.

    ABSTRACT: In Zimbabwe, many health facilities are not able to manage serious obstetric complications. Staff most commonly identified inadequate training as the greatest barrier to preventing avoidable maternal deaths. We established an onsite obstetric emergencies training programme for maternity staff in the Mpilo Central Hospital. We trained 12 local staff to become trainers and provided them with the equipment and resources needed for the course. The trainers held one-day courses for 299 staff at the hospital. Maternal mortality in Zimbabwe has increased from 555 to 960 per 100 000 pregnant women from 2006 to 2011 and 47% of the deaths are believed to be avoidable. Most obstetric emergencies trainings are held off-site, away from the clinical area, for a limited number of staff. Following an in-hospital train-the-trainers course, 90% (138/153) of maternity staff were trained locally within the first year, with 299 hospital staff trained to date. Local system changes included: the introduction of a labour ward board, emergency boxes, colour-coded early warning observation charts and a maternity dashboard. In this hospital, these changes have been associated with a 34% reduction in hospital maternal mortality from 67 maternal deaths per 9078 births (0.74%) in 2011 compared with 48 maternal deaths per 9884 births (0.49%) in 2014. Introducing obstetric emergencies training and tools was feasible onsite, improved clinical practice, was sustained by local staff and associated with improved clinical outcomes. Further work to study the implementation and effect of this intervention at scale is required.
