Rheumatoid arthritis and risk of osteoarticular infection and death following Staphylococcus aureus bacteraemia: A nationwide cohort study.

Following SAB, almost one in four patients with RA contracted OAI corresponding to a doubled risk compared with non-RA. In RA, orthopaedic implants and current TNFi use were associated with approximately doubled OAI risk. One in three died within 90 days in both RA and non-RA. These findings encourage vigilance in RA patients with SAB to avoid treatment delay of OAI.
