PURPOSE: The purpose of this study was to develop, implement, and evaluate a practice guideline using ketoconazole for the prevention of the adult respiratory distress syndrome (ARDS) in critically ill patients. MATERIALS AND METHODS: In hospital A (study hospital), we developed a guideline for ketoconazole prophylaxis in patients at high risk of ARDS using evidence from two randomized trials. We prospectively implemented the guideline using intensive care unit (ICU) teaching sessions, in-services, informational posters, and patient-specific individual audit and feedback. ICU caregivers in hospital B (concurrent control hospital) did not participate in the guideline development or implementation and were unaware of the conduct of the study. RESULTS: Patients at risk of ARDS were similar in hospitals A and B. Implementation of the guideline was associated with a significantly higher use of ketoconazole use for ARDS prevention (P < .0001) and a significantly lower rate of ARDS (P < .05) in hospital A compared with hospital B. Mortality, duration of ventilation, and ICU stay were similar. CONCLUSION: Development and implementation of a prophylactic ketoconazole practice guideline for ICU patients at high risk of ARDS was associated with a higher prescription of ketoconazole and a lower rate of ARDS in the study hospital than in the control hospital.
