BACKGROUND: Between the 1970s and 1990s, the World Health Organization promoted traditional birth attendant (TBA) training as one strategy to reduce maternal and neonatal mortality. To date, evidence in support of TBA training is limited but promising for some mortality outcomes.
OBJECTIVES: To assess the effects of TBA training on health behaviours and pregnancy outcomes.
SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (18 June 2012), citation alerts from our work and reference lists of studies identified in the search.
SELECTION CRITERIA: Published and unpublished randomised controlled trials (RCT), comparing trained versus untrained TBAs, additionally trained versus trained TBAs, or women cared for/living in areas served by TBAs.
DATA COLLECTION AND ANALYSIS: Three authors independently assessed study quality and extracted data in the original and first update review. Three authors and one external reviewer independently assessed study quality and two extracted data in this second update.
MAIN RESULTS: Six studies involving over 1345 TBAs, more than 32,000 women and approximately 57,000 births that examined the effects of TBA training for trained versus untrained TBAs (one study) and additionally trained TBA training versus trained TBAs (five studies) are included in this review. These studies consist of individual randomised trials (two studies) and cluster-randomised trials (four studies). The primary outcomes across the sample of studies were perinatal deaths, stillbirths and neonatal deaths (early, late and overall).
Trained TBAs versus untrained TBAs: one cluster-randomised trial found a significantly lower perinatal death rate in the trained versus untrained TBA clusters (adjusted odds ratio (OR) 0.70, 95% confidence interval (CI) 0.59 to 0.83), lower stillbirth rate (adjusted OR 0.69, 95% CI 0.57 to 0.83) and lower neonatal death rate (adjusted OR 0.71, 95% CI 0.61 to 0.82). This study also found the maternal death rate was lower but not significant (adjusted OR 0.74, 95% CI 0.45 to 1.22).
Additionally trained TBAs versus trained TBAs: three large cluster-randomised trials compared TBAs who received additional training in initial steps of resuscitation, including bag-valve-mask ventilation, with TBAs who had received basic training in safe, clean delivery and immediate newborn care. Basic training included mouth-to-mouth resuscitation (two studies) or bag-valve-mask resuscitation (one study). There was no significant difference in the perinatal death rate between the intervention and control clusters (one study, adjusted OR 0.79, 95% CI 0.61 to 1.02) and no significant difference in late neonatal death rate between intervention and control clusters (one study, adjusted risk ratio (RR) 0.47, 95% CI 0.20 to 1.11). The neonatal death rate, however, was 45% lower in intervention compared with the control clusters (one study, 22.8% versus 40.2%, adjusted RR 0.54, 95% CI 0.32 to 0.92).
We conducted a meta-analysis on two outcomes: stillbirths and early neonatal death. There was no significant difference between the additionally trained TBAs versus trained TBAs for stillbirths (two studies, mean weighted adjusted RR 0.99, 95% CI 0.76 to 1.28) or early neonatal death rate (three studies, mean weighted adjusted RR 0.83, 95% CI 0.68 to 1.01). 
AUTHORS' CONCLUSIONS: The results are promising for some outcomes (perinatal death, stillbirth and neonatal death). However, most outcomes are reported in only one study. A lack of contrast in training in the intervention and control clusters may have contributed to the null result for stillbirths and an insufficient number of studies may have contributed to the failure to achieve significance for early neonatal deaths. Despite the additional studies included in this updated systematic review, there remains insufficient evidence to establish the potential of TBA training to improve peri-neonatal mortality.
BACKGROUND: In some low- and middle-income countries, separate vertical programmes deliver specific life-saving interventions but can fragment services. Strategies to integrate services aim to bring together inputs, organisation, and delivery of particular functions to increase efficiency and people's access. We examined the evidence on the effectiveness of integration strategies at the point of delivery (sometimes termed 'linkages'), including integrated delivery of tuberculosis (TB), HIV/AIDS and reproductive health programmes.
OBJECTIVES: To assess the effects of strategies to integrate primary health care services on healthcare delivery and health status in low- and middle-income countries.
SEARCH METHODS: We searched The Cochrane Central Register of Controlled Trials (CENTRAL) 2010, Issue 3, part of the The Cochrane Library. www.thecochranelibrary.com, including the Cochrane Effective Practice and Organisation of Care Group Specialised Register (searched 15 September  2010); MEDLINE, Ovid (1950 to August Week 5 2010) (searched 10 September  2010); EMBASE, Ovid (1980 to 2010 Week 35) (searched 10 September  2010); CINAHL, EBSCO (1980 to present) (searched 20 September 2010); Sociological Abstracts, CSA Illumina (1952 to current) (searched 10 September  2010); Social Services Abstracts, CSA Illumina (1979 to current) (searched 10 September  2010); POPLINE (1970 to current) (searched 10 September  2010); International Bibliography of the Social Sciences, Webspirs (1951 to current) (searched 01 July 2008); HealthStar (1975 to September 2005), Cab Health (1972 to 1999), and reference lists of articles. We also searched the World Health Organization (WHOLIS) library database, handsearched relevant WHO publications, and contacted experts in the field.
SELECTION CRITERIA: Randomised controlled trials, non-randomised controlled trials, controlled before and after studies, and interrupted time series analyses of integration strategies, including strengthening linkages, in primary health care services. Health services in high-income countries, private public partnerships, and hospital inpatient care were excluded as were programmes promoting the integrated management of childhood illnesses. The main outcomes were indicators of healthcare delivery, user views, and health status.
DATA COLLECTION AND ANALYSIS: Two authors independently extracted data and assessed the risk of bias. The statistical results of individual studies are reported and summarised.
MAIN RESULTS: Five randomised trials and four controlled before and after studies were included. The interventions were complex.
Five studies added an additional component, or linked a new component, to an existing service, for example, adding family planning or HIV counselling and testing to routine services. The evidence from these studies indicated that adding on services probably increases service utilisation but probably does not improve health status outcomes, such as incident pregnancies.
Four studies compared integrated services to single, special services. Based on the included studies, fully integrating sexually transmitted infection (STI) and family planning, and maternal and child health services into routine care as opposed to delivering them as special 'vertical' services may decrease utilisation, client knowledge of and satisfaction with the services and may not result in any difference in health outcomes, such as child survival. Integrating HIV prevention and control at facility and community level improved the effectiveness of certain services (STI treatment in males) but resulted in no difference in health seeking behaviour, STI incidence, or HIV incidence in the population.
AUTHORS' CONCLUSIONS: There is some evidence that 'adding on' services (or linkages) may improve the utilisation and outputs of healthcare delivery. However, there is no evidence to date that a fuller form of integration improves healthcare delivery or health status. Available evidence suggests that full integration probably decreases the knowledge and utilisation of specific services and may not result in any improvements in health status. More rigorous studies of different strategies to promote integration over a wider range of services and settings are needed. These studies should include economic evaluation and the views of clients as clients' views will influence the uptake of integration strategies at the point of delivery and the effectiveness on community health of these strategies.
Traditional birth attendants (TBAs) and village midwives have been employed in many interventions to reduce maternal mortality in developing countries. This study reviews the results of 15 TBA- and midwife-based interventions that aim to improve skilled assistance in delivery and recognition and referral of complications. Outcome measures used to evaluate the impact of the programmes varied. Five of the five programmes reviewed that evaluated their impact on maternal mortality demonstrated a decline in maternal mortality ratios, two of three studies measuring morbidity-related indicators found improvement of some but not all morbidity outcomes, six of seven showed a trend of improved referral rates, and three of three found high levels of knowledge retention among trained TBAs. Programmes with the greatest impact utilised TBAs and village midwives within multisectoral interventions. These findings suggest that TBAs and village midwives contribute to positive programme outcomes. Further investigation is needed to determine the nature of their contribution within larger programmes.
