Spontaneous methicillin-sensitive Staphylococcus aureus spondylodiscitis-Short course antibiotic therapy may be adequate: Evidence from a single centre cohort.

Spontaneous methicillin-sensitive Staphylococcus aureus spondylodiscitis is increasing in prevalence and there appears to be little consensus on the optimum management of this condition. This paper analyses antimicrobial therapy and associated outcomes over a seven-year period at a large UK hospital trust. A retrospective search strategy identified 55 patients; notes were available for 39. Patients were treated with a median 12 weeks of antibiotics (IQR 7), with 6 weeks intravenous (IQR 3) and 9 weeks oral therapy (IQR 6). 23 different treatment regimens were utilised. 33/36 (92%) patients for whom outcomes were available were cured or improved at latest follow-up. This study reports a wide variation in antibiotic prescribing at a single centre. Outcomes were generally positive regardless of total duration of therapy and proportion of intravenous therapy. These findings highlight the need for multi-centre prospective randomised controlled trials to determine the most clinically effective and low-risk treatment strategy.
