Nudging Guideline-concordant Antibiotic Prescribing Using Public Commitments
Recruitment status was Active, not recruiting
Inappropriate antibiotic prescribing for acute respiratory infections (ARIs) persists despite decades of intervention efforts. Negative outcomes of inappropriate antibiotics include increased costs of care, adverse drug reactions, and rising prevalence of antibiotic-resistant bacteria. To address this public health problem, we apply the principles of commitment and consistency in an effort to influence clinician decision-making through the implementation of a low-cost behavioral "nudge" in the form of a simple public commitment device. Clinicians were asked to post in their exam room a signed letter indicating their commitments to reducing inappropriate antibiotic use for ARIs. Our hypothesis is that clinicians displaying the poster-sized commitment letters will decrease their inappropriate antibiotic prescribing for ARIs as compared to clinicians in the control condition (with no posted letter).

- Rate of inappropriate antibiotic prescribing for patients with acute respiratory infections [ Time Frame: up to 12 months post intervention ] [ Designated as safety issue: No ]Using data from electronic health records, we will calculate clinician antibiotic prescribing rates for antibiotic-inappropriate ARI diagnoses: acute nasopharyngitis (ICD-9 460.x), acute laryngitis without obstruction (465.8), acute laryngopharyngitis (465.0), acute bronchitis (466.x), acute upper respiratory infections of other multiple sites (465.8), acute upper respiratory infections not otherwise specified (465.9), bronchitis not specified as acute or chronic (490.x), non-streptococcal pharyngitis (462.xx), and influenza with other respiratory manifestations (487.1). To control for temporal trends in antibiotic prescribing and provider-fixed effects, we will fit a logistic mixed effects model that predicts inappropriate antibiotic prescribing as a function of study arm and an indicator for baseline versus intervention period (a difference-in-differences regression).

Experimental: Posted commitment letter
The poster-sized (18x24 inches) commitment letter, written at the 8th grade reading-level and displayed in English and Spanish, emphasize clinician commitment to guidelines for appropriate antibiotic prescribing and explain why antibiotics are not appropriate in many cases. These letters, featuring clinician photographs and signatures, are displayed in clinician exam rooms for a 16-week period.
|Other: Posted commitment letter|
No Intervention: Control
Usual care with no posted letters.
