- Abstract
Prospective audit and feedback (PAF) is considered an effective procedure for appropriate antibiotic use. However, its effect on the time to de-escalation is unclear. We aimed to evaluate the effect of daily PAF implementation, focusing on the time to de-escalation of anti-methicillin‐resistant Staphylococcus aureus (MRSA) agents as an outcome measure. To this end, a single-center, retrospective, quasi-experimental study including patients treated with intravenous anti-MRSA agents during pre-PAF (April 1, 2014 to March 31, 2015) and post-PAF (April 1, 2015 to March 31, 2016) periods was conducted. The time to de-escalation was estimated using the Kaplan–Meier method, and Cox proportional hazard analysis was performed to assess the effect of daily PAF implementation on the time to de-escalation. Interrupted time series analysis was used to evaluate the relationship between daily PAF implementation and anti-MRSA agent utilization data converted to defined daily dose (DDD) and days of therapy (DOT) per 1,000 patient days. The median time to de-escalation was significantly shorter in the post-PAF period than in the pre-PAF period (6 days vs. 7 days, P < 0.001). According to multivariate analysis, PAF implementation was independently associated with a shorter time to de-escalation (hazard ratio [HR], 1.18; 95% confidence interval [CI], 1.02 to 1.35). There were no significant differences in hospital mortality, 30-day mortality, and length of stay between the two periods. Interrupted time series analysis showed significant reductions in the trends of DDD (trend change, –0.65; 95% CI, –1.20 to –0.11) and DOT (trend change, –0.74; 95% CI, –1.33 to –0.15) between the pre-PAF and post-PAF periods. Daily PAF implementation for patients treated with intravenous anti-MRSA agents led to a shorter time to de-escalation and lower consumption of anti-MRSA agents without worsening the clinically important outcomes.
