Implementation of an interruptive electronic health record alert improves optimal antibiotic prescribing in ambulatory patients with acute bacterial sinusitis: a quasi-experiment

Sinusitis is a leading cause for outpatient antibiotics. An interruptive electronic health record alert was implemented to promote optimal antibiotic selection and duration for acute bacterial sinusitis when suboptimal treatment is ordered. After implementation, optimal antibiotic prescribing significantly increased 7% preintervention versus 30% postintervention, (unadjOR, 5.69; 95% CI, 2.36 - 13.72; P < .001).
