Abstract

:Induction of labor is best undertaken when continuing the pregnancy is thought to be associated with greater maternal or fetal risk with no contraindication to vaginal birth.Although induction of labor is commonly practiced, its success rate and factors affecting the success (vaginal birth) are rarely assessed in our settings. Objective: The objective of this study was to assess the magnitude of and factors associated with success of labor induction in Hiwot Fana Specialized University Hospital (HFSUH), 2020. Methods:A hospital based cross sectional study was conducted among mothers who underwent induction of labor from September 1, 2018 to August 31, 2020 in HFSUH.As induction of labor is rarely documented on the admission/discharge register or delivery logbooks, all deliveries during the study period were reviewed to identify all women who underwent induction of labor. Three trained midwives not working in the unit collected data on sociodemographic conditions, indications for induction and its outcome (success or failed) using a pre-tested structured questionnaire.Cleaned data were entered and analyzed using SPSS 23. Descriptive and inferential statistics werecomputed to identify factors associated with success of induction of labor. Results:A total of 4797 women gave birth in HFSUH during the study period. Of which 308 women who underwent induction of labor with complete chart were included making the prevalence of induction 6.4% in the study area. Two hundred sixty-onewomen gavebirth vaginally, making the magnitude of success of induction to be 84.7%.Of the women with failedinduction (47; 15.3%), the major indication for emergency cesarean section wasfailed induction (23; 48.9%). Parity (AOR 2.4; 95% CI 1.05, 5.42), method of induction(AOR 8.6; 95% CI 1.65, 45.18), and level of uterine contraction at induction (AOR=31.7; 95% CI 12.038, 83.7) were independently associated success of labor induction. Conclusion:Majority of women who underwent induction of labor delivered vaginally.Multiparity, induction with misoprostol, and achieving adequate uterine contractionwere significantly associated with success of induction.
