Trial Outcomes & Findings for Using Information Technology to Improve Asthma Adherence (NCT NCT00459368)

Results Overview

Adherence to ICS medication was measured during the last 3 months of the intervention (i.e., for the time period of 9-12 months post-randomization). Adherence was measured using pharmacy claims data, and represents the percent of prescribed medication taken. The normal range for this value is 0-100%.

Participant Flow

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.

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.

Participant milestones

Participant milestones
Measure	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.
