Episiotomy at the Royal Women's Hospital, Brisbane: a comparison of practices in 1986 and 1992

Statistical trends of episiotomy around the world: Comparative systematic review of changing practices

The authors' purpose for this article is to identify, review and interpret all publications about the episiotomy rates worldwide. Based on the criteria from the PRISMA guidelines, twenty databases were scrutinized. All studies which include national statistics related to episiotomy were selected, as well as studies presenting estimated data. Sixty-one papers were selected with publication dates between 1995 and 2016. A static and dynamic analysis of all the results was carried out. The assumption for the decline in the number of episiotomies is discussed and confirmed, recalling that nowadays high rates of episiotomy remain in less industrialized countries and East Asia. Finally, our analysis aims to investigate the potential determinants which influence apparent statistical disparities.

Perineal Assessment and Repair Longitudinal Study (PEARLS): a matched-pair cluster randomized trial

BACKGROUND

Perineal trauma during childbirth affects millions of women worldwide every year. The aim of the Perineal Assessment and Repair Longitudinal Study (PEARLS) was to improve maternal clinical outcomes following childbirth through an enhanced cascaded multiprofessional training program to support implementation of evidence-based perineal management.

METHODS

This was a pragmatic matched-pair cluster randomized controlled trial (RCT) that enrolled women (n = 3681) sustaining a second-degree perineal tear in one of 22 UK maternity units (clusters), organized in 11 matched pairs. Units in each matched pair were randomized to receive the training intervention either early (group A) or late (group B). Outcomes within each cluster were assessed prior to any training intervention (phase 1), and then after the training intervention was given to group A (phase 2) and group B (phase 3). Focusing on phase 2, the primary outcome was the percentage of women who had pain on sitting or walking at 10 to 12 days post-natal. Secondary outcomes included use of pain relief at 10 to 12 days post-natal, need for suture removal, uptake and duration of exclusive breastfeeding, and perineal wound infection. Practice-based measures included implementation of evidence into practice to promote effective clinical management of perineal trauma. Cluster-level paired t-tests were used to compare groups A and B.

RESULTS

There was no significant difference between the clusters in phase 2 of the study in the average percentage of women reporting perineal pain on sitting and walking at 10 to 12 days (mean difference 0.7%; 95% CI -10.1% to 11.4%; P = 0.89). The intervention significantly improved overall use of evidence-based practice in the clinical management of perineal trauma. Following the training intervention, group A clusters had a significant reduction in mean percentages of women reporting perineal wound infections and of women needing sutures removed.

CONCLUSION

PEARLS is the first RCT to assess the effects of a 'training package on implementation of evidence-based perineal trauma management. The intervention did not significantly improve the primary outcome but did significantly improve evidence-based practice and some of the relevant secondary clinical outcomes for women.

The role of the midwife in perineal wound care following childbirth

Midwives have an important role to play in the care of perineal wounds following childbirth. A wide variety of practices are carried out in this area. However, some current practices may not be beneficial to the promotion of wound healing. Midwives must realize the relevance of their care and potential impact, both positive and negative, of advocated treatments in wound healing. The maintenance of effective pain relief must be balanced with the need to promote wound healing. It is important that midwives recognize the need for research-based practice and that an audit is set up nationally to evaluate the efficacy of treatments and practice. Research, audit and evaluation of services are the central processes involved in providing effective and efficient care, as advocated by the Department of Health (1993).
