3.5. Factors associated with management outcome of intestinal obstruction
In the following table twenty two variables were analyzed using binary logistic regression. Out of this age, sex, educational status, duration of illness, hematocrit level, and previous history of abdominal operation, pre operative complication, and type of obstruction, intraoperative findings and length of hospital stay were candidates for multivariate analysis.
3.6. Predictors of management outcome of small bowel obstruction
Numerous associations were found to be significant in the bivariate analysis. Therefore, a multivariate approach was applied to determine which factors best explained and predict management outcome of patients
The outcome of the final multiple logistic regression model indicated that educational status, hematocrit level, previous history of abdominal operation, type of obstruction , intraoperatve finding & length of hospital stay were dropped from the final model. In this analysis age ranges between 45-54 has significant statistical association with management outcome of patients (AOR=0.001, 95%CI: 0.000-0.290, p-value=0.016), the minimum &maximum age was 04 months & 76 years with mean age of 27.2 years(sd±19.2) and also sex has significant statistical association with management outcome of patients (AOR=0.037, 95%CI:0.001-1.454, p-value=0.048). Female patients had higher 96.3 % poor management out come as compared to male patients.
Duration of illness before surgical intervention has significant statistical association with management outcome of patients (AOR=0.069, 95%CI: 0.004-1.217, p-value=0.036). Patients who presented within 24 hours duration of illness are 92.1% less likely to develop unfavorable outcome as compared with patients who presented after 24 hours and pre operative complication has also statistically significant association with management outcome of patients (AOR=0.099, 95%CI: 0.013-0.782, p-value=0.028), indicating that Those patients who were with pre operative complication had 90.1% poor management out come as compared to those without complication.
