Magnitude, outcomes and factors associated with induction of labor among mothers who gave birth at attat primary hospital, gurage zone, south region, Ethiopia, 2017

Abstract

Background: Induction of labor performed following an appropriate medical and obstetrical indication is potentially life-saving procedure. Induction is indicated when the benefits to either mother or fetus outweigh those of pregnancy continuation. Induction is expected not only to achieve vaginal delivery but also to improve both maternal and perinatal outcomes in comparison with permitting pregnancy to continue. Objective: To determine the magnitude of induced labor and associated factors for success of induction among mothers gave birth at Attat primary hospital Gurage zone, Ethiopia from, 2017. Methods: Institutional based Prospective Cross sectional study design was conducted on 110 pregnant mothers from January 1, 2017 to June 30, 2017 G.C at Attat primary Hospital.6 data collectors and 2 supervisors were trained and involved in data collection process. Then data collected using structured questionnaire which was prepared in English and face to face interview was applied to collect the data. Data was checked and coded and analyzed using SPSS version 22. Descriptive statistics (frequency percentage, mean and standard deviation) was used to describe the study variables. An odds ratio (95% confidence intervals) and Logistic regression analysis was used to determine the association of different factors with success of induction of labor. A P<0.05 was considered statistically significant in all tests of significance Result: A total of 110 women were induced, 6.4% of women who undergone induction had failed induction. Oxytocin IV infusion was the most method used for the purpose of induction and premature rupture of labor was the leading indication for induction (44.5%). Bishop score, AOR=14.2 (3.1-64.5), gravidity, AOR=5.7(1.42-22.98), Mothers who had cervical ripening before induction AOR= (1.06-67.23), and induction by intravenous oxytocin, AOR=7.8(2.11-28.94) has been shown to be the main predictor of successful induction. Conclusion and recommendation: The magnitude of induction of labor in this study was low and majority of the outcome is success. Bishop score, gravidity, cervical ripening and induction by intravenous oxytocin, fetal weight had association with success of induction and recommended to assess the cervix status (using the Bishop score), preinduction cervical ripening before induction is recommended for the success of induction.
