INFECTION PROFILE IN HIP ARTHROPLASTY AT A REFERRAL HOSPITAL

To analyze the occurrence of infections in patients undergoing hip arthroplasty at a tertiary hospital in Teresina, Piauí, Brazil, between 2020 and 2023.

A retrospective, longitudinal, and observational study conducted at Hospital Getúlio Vargas, Teresina, Piauí, with patients who developed prosthesis-related infections during the study period.

A total of 1,420 surgeries were performed, with an infection rate of 2.0% (22 cases). Female patients predominated (59.1%) with a mean age of 68.8 years. Trauma was the main surgical indication (77.3%). Total arthroplasty was performed in 68.2% of cases, with 59.1% done without cement. The most common pathogens were Escherichia coli (22.7%) and Acinetobacter baumannii (18.2%). The main antibiotics used were ciprofloxacin (31.7%), clindamycin (25%), and vancomycin (15%). Hospital discharge occurred in 86.4% of cases, with no significant association between variables and outcomes (p > 0.05).

The findings highlight the importance of preventive protocols and surveillance to reduce infections in hip arthroplasty. Level of Evidence II; Retrospective Study.
