Abstract

Background: Surgical site infection (SSI) is the dominant cause of unplanned and potentially preventable hospital readmissions in surgical patients. The main objective of this study is to determine the risk factors of SSI among patients undergoing inguinal hernia operation.

Materials and Methods: We conducted a hospital-based case control study from March 30, 2017, to November 29, 2017, on a total of 176 patients undergoing inguinal hernia operation in a public Hospital of Dhaka. We used a semi-structured questionnaire to collect data on patients’ characteristics and a checklist containing three questions to identify the SSI.

Results: The mean age of the study population was 42 years among case group and 44 years among the control group. The multivariate analysis reflects the risk factors associated with SSI are age of above 35 years (OR= 3.84, CI=1.41-11.39), day-labor (OR= 3.032, CI = 1.23-7.79), employed (OR = 3.650, CI= 1.16-8.46), and having diabetes more than 5 years (OR= 4.160, CI= 1.54-13.26). We also found 5.7% of cases showed Methicillin Resistance Staphylococcus Aureus growth, and 58.0% of cases showed Methicillin non- Resistance Staphylococcus aureus growth.

Conclusion: The identified risk factors for the SSI reflect a complex interaction among socio-demographic conditions. Although further study is warranted to validate these results, the socio-demographic factors presented may be a useful tool to stratify patient risk of SSI.
