MRSA: treating people with infection
Abstract
INTRODUCTION: Methicillin-resistant Staphylococcus aureus (MRSA) has a gene that makes it resistant to methicillin as well as to other beta-lactam antibiotics including flucloxacillin, beta-lactam/beta-lactamase inhibitor combinations, cephalosporins, and carbapenems. MRSA can be part of the normal body flora (colonisation), especially in the nose, but it can cause infection, especially in people with prolonged hospital admissions, with underlying disease, or after antibiotic use. About 20% of S aureus in blood cultures in England, Wales, and Northern Ireland is resistant to methicillin.
METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatment for MRSA infections at any body site? We searched: Medline, Embase, The Cochrane Library and other important databases up to November 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS: We found 11 systematic reviews, RCTs, or observational studies that met our inclusion criteria.
CONCLUSIONS: In this systematic review we present information relating to the effectiveness and safety of the following interventions: clindamycin, daptomycin, fusidic acid, glycopeptides (teicoplanin, vancomycin),…
How strong is the evidence?
Evidence Hub reads this as a systematic review, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid.
