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
