Failed Induction of Labor and Associated Factors among Women Delivered in Hawassa Public Health Facilities, SNNPR, Ethiopia

Abstract

Background: Induction of labor is an increasingly being done obstetric procedure throughout the world. It is carried out in approximately 20% of all pregnancies. It is associated with poorer outcomes when compared with spontaneous labor. Objective: To determine the prevalence of failed induction of labor and identify associated factors in Hawassa public health facilities, SNNPR, Ethiopia. Method: institution based cross sectional study was carried out on medical records of 294 women admitted for induction of labor in Hawassa public health facilities from 1st Jan, to 31st Dec, 2014. Systematic sampling technique was used to select samples. Six diploma nurses were hired to collect the data. Data were collected by pretested structured checklists then entered into Epi-Data version 3.1 to control data entry errors. Then data were analyzed with Statistical Package for Social Science, version 21. First percentage, frequency and mean were calculated. Then, multivariable logistic regression analysis was done to evaluate the possible association of all variables that were candidate after binary logistic regression analysis. P-value less than 0.05 in multivariable logistic regression was considered to be statistically significant. Finally the result was summarized and presented in texts and charts. Result: The prevalence of failed induction of labor was 17.3%. Advanced maternal age [AOR 8.85 (2.60-30.05)], primiparity [AOR 3.12 (1.01-9.62)], poor Bishop Score [AOR 4.42 (1.52-12.84)], greater for gestation [AOR 7.21 (2.45-21.19)], bad obstetric history [AOR 5.64 (1.38-23.02)], post term [AOR 4.34 (1.17-16.11)] and premature rapture of membrane [AOR 7.12 (2.83-17.89)] were significantly associated with failed induction of labor. Conclusion and recommendation: advanced age, primiparity, unfavorable bishop score, premature rapture of membrane, greater for gestation and bad obstetric history had positive association with failed induction of labour. Women with increased risks for failure of induction of labor should be approached with caution
