Tesfaye Getachew, Ayele Taye and Shibiru Jabessa

Kaplan-Meier estimation method, Cox proportional hazard model and parametric regression model were applied. The Cox proportional hazard analysis indicated that older ages at first marriage, weight <50 kg, height of >150 cm, follow up of antenatal care, delivery at health center, duration of labour for <2 day, vaginal delivery, length and width of fistula <5 cm and intact of urethra significantly contribute to shorter stay in hospital to treated and physically cured. The result from Weibull regression analysis showed that older age at first marriage (adjusted HR=1.00), weight<50 kg (HR=0.409), height of >150 cm (Adjusted HR=1.00), follow up of antenatal care (adjusted HR=0.263), delivery at health center (adjusted HR=1.00), duration of labour (adjusted HR=0.127 for <2 day), vaginal delivery (adjusted HR=0.241), length of fistula (adjusted HR=0.342 for <2 cm, HR=0.426 for 3-5 cm), width of fistula (adjusted HR=0.147 for <2 cm, HR=0.356 for 3-5 cm) and intact of urethra (adjusted HR=0.439) significantly contribute to a shorter recovery time of a patient. In conclusions: The finding of this study showed that age at first marriage, height, antenatal care, weight, place of delivery, mode of delivery, duration of labour, length and width of fistula, and status of urethra were major factors affecting recovery time of obstetric fistula patient at Yirgalem Hamlin Fistula Hospital. It is recommended to make interventions based on these risk factors.
