1. INTRODUCTION We compared the severity of symptoms in women with OASIS from (NVD), forceps (F),vacuum (V) and vacuum & forceps (V&F) and grouped them accordingly. Symptoms were evaluated with a telephone questionnaire at 6 weeks postpartum. Women who were asymptomatic were not reviewed further. Symptomatic women were assessed at 12 weeks at their first physiotherapy appointment. Symptoms declared at 6 weeks were compared to the symptoms at 12 weeks. In all of the groups, patients presented with more than one symptom at 6weeks and 12 weeks. A total of 106 OASIS injuries from June 2013 to June 2014 were reviewed in this study. Postpartum Symptom Review of Obstetric- Associated Anal Sphincter Injury (OASIS) comparing Normal Vaginal Delivery (NVD) with Assisted Vaginal Delivery. Wiseman S 1, O’Sullivan S 2, O’Reilly B 2, Barry L 3 METHOD Questions from the Pelvic Floor Distress Inventory Questionnaire-20 and the Queensland’s Pelvic Floor Questionnaire were used to look at bladder, bowel and pelvic floor pain symptoms as well as sexual function at 6 and 12 weeks postpartum. Symptoms specific to physiotherapy including pelvic girdle and coccyx pain were also assessed at 12 weeks at their first physiotherapy review.

Email:shalini.wiseman@hse.ie : CONCLUSION We found that at 6 weeks, women with OASIS from vacuum & forceps deliveries had significantly greater symptoms when compared to women who were delivered using single instrument or with NVD. The NVD group had the highest number of asymptomatic women at follow up. We found that the telephone assessment at 6 weeks allowed us to prioritise all symptomatic women. 6 weeks physiotherapy review is appropriate as no further natural resolution of symptoms were seen in any group between the 6 to 12 weeks period. We recommend prioritising patients with OASIS(V&F) for physiotherapy as they are in the highest risk group due to greater severity in symptoms. A further study to review the outcome of the groups at a year post partum, on completion of physiotherapy treatment will be done.
