Trends in obstetric anal sphincter injuries over 10 years.
Obstetric anal sphincter injuries (OASIS) is a known complication of vaginal delivery and has significant public health issues, as it can cause both short- and long-term morbidity in women. The most commonly reported complications include different grades of faecal/flatus incontinence, pain and sexual dysfunction. In our study, we found a rising trend in OASIS rates in vaginal deliveries, with the rising rate of forceps and the falling rate of SVD, which is at least partly due to increased awareness and training in OASIS. However, there is an actual increase in the number of such tears at vaginal deliveries. Midwifery and obstetric practices have certainly changed over the last decade and we discuss the possible factors, which might be contributing to such a rise.
