Outcomes and metrics for antimicrobial stewardship: survey of physicians and pharmacists.

ABSTRACT

We conducted a survey to compare antimicrobial stewardship outcomes considered to be most important with those used in practice as metrics. Respondent opinion of important outcomes compared with those collected as metrics were antimicrobial use (15% vs 73%), antimicrobial cost (10% vs 73%), appropriateness of antimicrobial use (56% vs 51%), infection-related mortality rate (34% vs 7%), and antibiotic-associated length of stay (22% vs 12%). Patient outcomes are important to many practitioners but are rarely used as metrics.
