Determining Factors of Periprosthetic Infection: A Proposal for a Cross-Cutting Study in An Ecuadorian Referral Hospital

Abstract

The objective of this research was to determine the factors associated with the development of periprosthetic infection in patients undergoing prosthetic joint replacement. A descriptive and retrospective study was conducted with 478 patients who underwent surgery at a Specialty Hospital in Quito, Ecuador, between January 2010 and December 2015. The results showed that 3.8% of the patients presented periprosthetic infection, and a significant association was found between infection and urinary tract infection and smoking. In addition, the National Nosocomial Infections Surveillance Index (NNIS) showed that patients with moderate-high risk had a 7.47 times higher risk of infection. In conclusion, there are modifiable factors associated with periprosthetic infection, and the NNIS index can provide a quick and easy estimate of the risk of developing this complication.
