This is a multicenter intervention study aiming at reducing the incidence of perineal injuries during vaginal delivery in Palestine and it will explore the complications that occur during childbirth as well as the management of these complications. In addition, this study will also explore whether the effect of “interactive hands-on training” or “non-interactive training by animated instruction” differs in improving hands-on delivering techniques of health care providers and whether it reduces the incidence of obstetric anal sphincter injuries (OASIS). The study will be conducted in six Palestinian governmental hospitals including the Palestine Medical Complex in Ramallah, Rafidia Hospital in Nablus, Alia Hospital in Hebron in the West Bank, and Al Helal Emirati Hospital, Shada Al Aqsa Hospital, and Shifa Hospital in Gaza, for a duration of three years (2015-2017). The study will also provide an opportunity for three Palestinian Obstetrician consultants to do their PhD at the University of Oslo. The study will be carried out in collaboration with the Palestinian Ministry of Health, the Oslo university hospital and the University of Oslo. Dr Sahar Hassan is a post-doctoral, principal investigator, and supervisor for two PhD students.
