Statistical Methods and Management of Indeterminacy in Medical Sciences. Surgical Site Infection Study after Vascular Surgery Procedures

Abstract

Surgical site infections (SSIs) are one of the main infection control problems in modern hospitals, significantly prolonging the stay at the hospital and increasing the cost of treating patients with infections. They are the leading cause of failure for both patients and staff, including the need for repeated surgeries. The objective of this study is the epidemiological and microbiological analysis, through neutrosophic statistical tools, of surgical site infections after vascular surgery in a highly specialized vascular surgery center in the city of Guayaquil, in which 327 vascular operations were performed, during the year 2019 and the follow-up of patients was taken into account as required, until 2020. The neutrosophic hypothesis tests applied allowed us to identify possible problems in the vascular surgery room from their comparison with multicenter studies described in the literature, specifically, from the National and State HAI Progress Report of the USA, as well as to rule out the classification of the state of the patient as a possible predictor of SSI diagnoses at this hospital.
