Determinants of puerperal sepsis among postpartum women at public hospitals of Hawassa city, Southern Ethiopia: Institution-based unmatched case-control study

Abstract

Background: World health organization reported that from 358,000 maternal deaths occurring during labor and childbirth about 15% were attributed to puerperal sepsis. In Ethiopia, puerperal sepsis is the fourth leading direct cause of maternal death next to hemorrhage, obstructed labor, and pregnancy-induced hypertension. Early recognition and management of the contributing factors would help to modify the problem. Therefore, this study was aimed to identify the determinants of puerperal sepsis among postpartum women at Hawassa city public hospitals in South Ethiopia.

Methods: & materials: Institution-based unmatched case-control study was conducted among 305 postpartum women (61 cases & 242 controls; with a ratio of 1:4) at Hawassa city public hospitals from June 17 to August 20/2021. Cases were all postpartum women admitted with puerperal sepsis and controls were randomly selected postpartum women admitted with other cases. A pre-tested interviewer-administered questionnaire was used to collect the data. Data were entered into Epi data version 4.6 and then exported to STATA version 14 for analysis. Bivariable analysis was performed and variables having a p-value <0.25 made candidates for the multivariable logistic regression model. Adjusted Odds ratio (AOR) with 95% confidence interval was computed to identify the presence and strength of association and statistical significance was declared at p-value <0.05.

Result: In this study, a total of 61 cases & 242 controls were included. Cesarean section delivery (AOR = 2.85; 95% CI; 1.36-5.98), manual removal of placenta (AOR = 6.0; 95% CI = ; 0.39-26.26), ≥5 times Per-vaginal Examination during labor (AOR = 4.53; 95% CI; 2.10-9.80), presence Gestational Diabetes Mellitus (AOR = 8.50; 95% CI; 1.99-36.33) & prolonged labor (AOR = 3.43; 95% CI; 1.20-9.76) were identified as determinants of puerperal sepsis.

Conclusion: In this study, cesarean delivery, Per-vaginal Examination ≥5 times during labor, manual removal of placenta, Gestational Diabetes Mellitus & prolonged labor were factors that significantly increased the odds of developing puerperal sepsis among postpartum women. So, labor & delivery procedures should be conducted as per labor & delivery management protocols.
