To investigate the types and frequency of organisms causing surgical site infections in postoperative patients and their association with other factors.

Study Design:


Duration and Place of Study:

Surgical Unit-II of –removed for blind review---and from 1st March 2021 – 31st July 2021.

Patients and Methods:

There were 391 surgeries in this study, but only 27 patients met the inclusion criteria. A diagnosis of SSI was based on specific parameters, including the detection of two or three cardinal signs of inflammation and the surgeon's confirmation of the diagnosis. This data was analyzed using IBM SPSS 23.


Among 391 patients, 242 had elective surgeries (male:female, 1.6:1), and 149 had emergency surgeries (male:female, 1:3.4). The mean length of stay for elective surgeries was 2.19 ± 1.8 days and 4.2 ± 3.7 days for emergency procedures.

There were 98 abdominal procedures (65.77%) performed in emergency settings. Only 9 (3.71 %) elective procedures and 18 (12.08 %) emergency procedures reported surgical site infections. Escherichia coli was the most commonly isolated organism from SSI during the study. The rate of SSI in postoperative patients was 6.9%.

There was a statistically significant association between SSI and type of surgery (p=0.002). The mean length of stay (LOS) was longer for patients with SSI (mean=12.5, p=.000).  Emergency cases had a longer LOS compared with elective cases (mean= 4.21 days vs 2.19 days, p=.000).


According to our study, our unit's SSI were comparable to other developing countries. SSI are more frequent in emergency cases, men, and diabetics, and are the primary cause of longer hospital stays.
