Trauma to the perineum following vaginal delivery is common and can lead to anal incontinence and pain but can be prevented by perineal support. However, the incidence and how to prevent perineal injury in sub Saharan Africa has not previously been described. The objective of the study was to assess the incidence of perineal trauma at vaginal delivery and to assess a training intervention in perineal support using a criterion-based audit (CBA) design. A CBA was conducted at Kilimanjaro Christian Medical Centre in Tanzania. In total, 552 women who delivered vaginally were included, of whom 80% completed a follow-up interview after three months. Perineal support as trained for this study was not performed before the intervention but was performed in 78.6% of deliveries after the intervention (p<0.000). The number of women with second degree lacerations decreased after the intervention (RR 0.74, CI: 0.61-0.90), and more had an intact perineum (RR 2.85, CI: 1.74-4.69). Anal sphincter lacerations were not significantly changed by the intervention (6.6 to 3.4%, RR 0.52, CI: 0.24-1.14). The frequency of anal incontinence changed insignificantly from 6.1 to 4.9% (RR 0.81, CI: 0.37-1.77) after intervention. Perineal pain three months after delivery was reduced by 72% (RR 0.28, CI: 0.15-0.52). The study demonstrates that CBA may be useful in introducing a simple intervention such as perineal support thereby decreasing the number of women having perineal trauma following vaginal delivery. However, the impact of our intervention on the sustainability of our observations is uncertain and must await long-term studies.

The use of cesarean section (CS) and oxytocin for labour augmenttion may contribute to increase morbidity and mortality of mothers and newborns. The objective of the study was to evaluate the Criterian Based Audit (CBA) on CS rates and oxytocin use in labouring women. A prospective intervention study by CBA was performed at hospital in Tanzania. Included were 523 labouring women at a gestational age of at least 28 weeks and birth weight ≥1000 g. All data on actual care were compared to criteria for best practice agreed with the staff. Interventions were discussed with the staff followed by a training session. At follow up, data were achieved from 438 women. Performance and outcomes were compared before and after the intervention. The overall CS rate decreased from 46.1 to 38.4% (RR=0.83; CI: 0.72 to 0.97). The use of oxytocin decreased from 76.2 to 47.3% (RR=0.63; CI: 0.45 to 0.85). The study demonstrates suboptimal care in labour monitoring and management, and that CBA resulted in a reduction in CS and use of oxytocin, and suggests that CBA can be used for quality assurance of women's health care.
