Treatment for bone and joint infection (BJI) is not standardized, which allows a wide range of antibiotic therapy to potentially be given, most often in high doses over long periods of time. Patients are regularly confronted with the adverse effects of these antibiotics, which can lead to loss of adherence and treatment failure. The frequency, severity and impact on quality of life of the adverse effects of long-term antibiotics will be studied in a cohort followed for one year.

Treatment for bone and joint infection is not standardized, which allows a wide range of antibiotic therapy to potentially be given, most often in high doses over long periods of time. Patients are regularly confronted with the adverse effects of these antibiotics, which can lead to loss of adherence and treatment failure. Although patients with BJI receive regular follow-up, the impact of adverse events during treatments lasting more than a month is still poorly developed in the literature.

The frequency, severity and impact on quality of life of the adverse effects of long-term antibiotics will be studied in a cohort followed for one year.

The investigators believe that this study will improve the management of osteoarticular infections through a better understanding of the adverse effects associated with prolonged, high-dose antibiotic therapy, and encourage more multidisciplinary follow-up.

Inclusion Criteria:

• Microbiologically proven osteoarticular infection with or without material, requiring antibiotic therapy (single or multiple) of 6 weeks or more
• Oral antibiotic therapy (minimum 4 weeks)
