Background:

Surgical Site Infections (SSI) afterelective/emergency laparotomy contributes topostoperative morbidity, mortality and resourceutilization. Risk factors related to abdominal SSIs arewell known. Nevertheless, National data guide effortsto improve efficiency, which cannot identify specificorganizational risk factors. Aim and

Objectives:

Todescribe the prevalence and risk factors associated withSSI in patients undergoing laparotomy. Material and

Methods:

Descriptive, observational study of elective/emergency laparotomy patients uses institutional datafrom 2017-2019. Univariate and Multivariable logisticregression identified risk factors associated with SSIdevelopment.

Results:

Of 393 patients studied. 88developed SSI (superficial 19.60%, deep 2.30%, organspace 0.50%), age (40-60 years), males, Body MassIndex (BMI) >25, smoking, diabetes, alcohol, higherwound class, low hematocrit, low serum albumin,Longer duration of surgery were associated withincreased SSI rate. Associated co-morbidities, Lowhematocrit and higher duration of surgery weresignificant independent risk factors (p<0.05).

Conclusion:

Institutional SSI modeling shows thatmany previously suggested nationally defined riskfactors do not contribute to SSI, at our institution.Identifying SSI's institutional contextual predictors,rather than relying on external data assumptions, is avital endeavor to promote quality improvements andmaximize the value of quality investments.
