* To whom correspondence should be addressed. Objectives: Linezolid, the first available agent in the new class of oxazolidinone antibiotics, represents a significant advance in the management options available for combating methicillin-resistant Staphylococcus aureus (MRSA) infections. In the UK it was launched for clinical use in 2001. The aim of this study was to audit the clinical use of linezolid and compliance with the guidelines of the hospital antibiotic committee. Methods: Our hospital antibiotic committee agreed clinical indications for linezolid use. We undertook an audit of compliance with these recommendations and also reviewed its use in terms of the source of infection, microbiology, duration of therapy, side-effects and choice of previous treatment. Results: Seventy-seven inpatients prescribed linezolid in Ninewells Hospital in the 3 years between March 2001 and September 2003 were audited. Overall compliance with our local recommendations appears to be very good. The main justification for using linezolid is the presence of existing or worsening renal dysfunction or poor venous access (34%) or lack of tolerance or clinical failure following glycopeptide monotherapy or combination therapy (32%). Skin and soft tissue infections (26%) were the most frequently diagnosed infections, although an increasing number of patients appear to receive linezolid for the treatment of lower respiratory tract infections, primarily in the ICU for nosocomial or ventilator-associated pneumonia. MRSA organisms were the most common cause of microbiologically proven treated infections [n = 43 (56%)]. Disappointingly, only 34 out of 77 patients had case record documentation of prior approval by an infection specialist. Conclusions: The use of linezolid in our hospital appears to follow local guidelines, but the quality of information recorded in the notes could be optimized. Consequently, a linezolid mandatory order form to be completed by the attending prescribing clinician has been introduced, and will be subject to future evaluation. We recommend such specific antibiotic utilization reviews or audits of new agents introduced into clinical infection practice.
