Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Health system primary care providers (i.e., in the areas of family practice, internal medicine, and pediatrics) were invited to participate. Physicians who consented to participate were grouped according to practice.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
One hundred ninety-two (92%) of the 207 primary care staff clinicians, representing 34 pre-defined primary care practices within the health system, agreed to participate. One clinic was not included a priori since it functioned as the primary resident clinic for internal medicine trainees.

Reporting Groups
  Description
Patient Medication Adherence Feedback In this cluster-randomized trial physicians practicing at intervention clinic sites will receive adherence information on their patients with asthma who are currently taking an inhaled corticosteroid medication. This information will be available to them via our electronic prescribing software to discuss with patients at the time of the visit. Physicians at these sites also receive standardized training in how to interpret and intervene when poor adherence is identified.
Usual Care Physician practicing at control sites are given standard training in how to intervene on poor adherence, but no patient adherence information is provided to these clinicians via electronic prescribing software.
