Enhancing recognition of obstetric anal sphincter injuries in six maternity units in Palestine: an interventional quality improvement study.

This work is basically an epidemiological study which has identified the prevalence of perineal lacerations and their severity on a large sample of women representative of an entire geographical ethnic region. The quality improvement intervention improved OASIS detection mainly in the research fellows' maternity units. Regular mandatory national programmes in obstetric perineal trauma assessment and management by local champions are essential to mitigate the risk of missing significant degrees of trauma.
