Analysis of The Elements Related to The Appearance of Joint Prosthesis Infections in A Hospital Center in Quito, Ecuador

Abstract

Aim: The prosthetic joint replacement procedure is a significant advance in medicine, improving functionality and quality of life in patients with arthropathies. Although it offers many benefits, it is exposed to complications, periprosthetic infection being one of the most worrisome. This infection affects the patient's quality of life; therefore, it is crucial to identify the risk factors associated with this complication. Material and method: The objective of this study is to determine the factors linked to the development of this infection in patients undergoing prosthetic joint replacement. A descriptive and retrospective approach was used, analyzed with descriptive statistics, frequency, percentage and chi square, using the SPSS system ver 2.0. Patients operated on in a prestigious Specialty Hospital in the city of Quito, Ecuador, from January 2010 to December 2015 were analyzed. The study included 478 patients, 62.6% being women, with a mean age of 70.3 years. Statistics and Result: Hip arthroplasty was the most frequent intervention (59.2%). The overall incidence of periprosthetic infection was 3.8% (n=18). During the analysis, urinary tract infection and smoking were identified as being associated with periprosthetic infection. The NNIS index showed that patients with moderate-high risk are 7.47 times more likely to develop infections.
