Perineal outcome following educational intervention: a retrospective audit of primiparous women.

The management of vaginal delivery appears to offer an opportunity to reduce the morbidity of pelvic floor dysfunction (PFD) which is very common in the postpartum period. Research by the authors suggests that an episiotomy is protective against PFD, in particular urinary incontinence. The aim of this subsequent audit was to see if educational intervention can alter the common medical practice of episiotomy and in turn reduce postpartum PFD. Nine hundred and fifty four primiparous women with a non-instrumental vaginal delivery were included, of which 30% had an intact perineum, 51% a spontaneous tear and 19% an episiotomy. The intervention was a teaching session by the Head of Urogynaecology encompassing the anatomy, the impact of a vaginal delivery on PFD, in addition to local and international research. Whilst no significant difference was noted overall in the episiotomy rates as a result of the educational intervention (p = .17), significant differences were noted with the different accoucheur types. Where the accoucheur was an obstetrician or obstetrics registrar, the episiotomy rates increased from 56% to 70% (p < .01); where the midwife was the accoucheur the episiotomy rate changed minimally (11-18%, respectively; p = .27). This demonstrates that feedback about the provider's own practice patterns can change the behaviour to conform with the agreed upon standards. Impact Statement What is already known on this subject? Pelvic floor dysfunction (PFD) is the most common complication of childbirth, affecting approximately 85% of Australian women following a vaginal delivery. A link has been made between the perineal outcome and PFD, which has a significant impact on the quality of life. Previous research suggests that the management of a vaginal delivery offers an opportunity to reduce its morbidity, with an episiotomy being protective. However, there is a wide variation in the use of episiotomy which ranges from 9% to 100%. What the results of this study add? The literature suggests that the strongest factor associated with the episiotomy rates arises from differences in the attitude and training. Consequently, this study explored whether an educational intervention can change the common medical practice of episiotomy and in turn reduce postpartum PFD. What are the implications of these findings for clinical practice and/or further research? No significant difference was noted overall in the episiotomy rates as a result of the educational intervention, however, the response to the educational intervention was varied among the different types of accoucheurs with the obstetricians, obstetric registrars and student midwives significantly increasing their rate of episiotomy, whilst the midwives demonstrated no significant change. This suggests that there are contributing factors which may include past education and experience; this is an area for further research.

Perineal outcome and the risk of pelvic floor dysfunction: a cohort study of primiparous women.

BACKGROUND: Pelvic floor dysfunction (PFD) is the most common complication of childbirth. Assumptions have been made that perineal trauma increases the risk of PFD compared to an intact perineum, however the evidence for this is lacking. The aim of this study was to explore the relationship between perineal outcome and postpartum PFD. MATERIALS AND METHODS: Prospective cohort study design, with a self-reported quality of life (QOL) questionnaire mailed to all primiparous women with a non-instrumental delivery at The Townsville Hospital between 2011 and 2012 (n = 766). ANOVA was used to compare how the symptoms of PFD affect QOL in women with an intact perineum, episiotomy or spontaneous tear. RESULTS: Seventy-nine percent of the population had perineal injury; 60% had a spontaneous tear and 19% had an episiotomy. Ninety-seven percent of women who completed the questionnaire (n = 196) complained of PFD symptoms. Women with episiotomy had the best QOL, reporting the lowest levels of urinary dysfunction (statistically significant). No differences between the groups were found for symptoms of bowel, prolapse or sexual dysfunction. CONCLUSIONS: This study shows a relationship between perineal outcome and PFD and suggests that an episiotomy is associated with the least morbidity due to symptoms of urinary incontinence. Additional large-scale prospective research is required to further investigate and delineate the impact of childbirth on PFD.
