Impact of antibiotic prophylaxis in second-stage surgery in joint prosthesis infection treated with two-stage exchange. A multicenter case-control study.

Introduction: After two-stage exchange due to prosthetic joint infection (PJI), the new prosthesis carries a high risk of reinfection (RePJI). There isn`t solid evidence regarding the antibiotic prophylaxis in 2nd-stage surgery. The objective of this study is to describe what antibiotic prophylaxis is used in this surgery and evaluate its impact on the risk of developing RePJI.

The high use of antibiotics in the community is closely related to the increase in resistance to antibiotics. Monitoring antibiotic use is a key step to understanding whether trends are changing, and in this way efforts towards more prudent use can be implemented. Over the last 9 years, available active ingredients have decreased in Spain while at the same time the number of antibiotic offerings has increased.
