A Randomized Controlled Trial to Evaluate the Effectiveness of a Distance Asthma Learning Program for Pediatricians

Abstract

Objectives. To assess provider acceptability of a distance learning program for pediatric asthma and pilot test its effects on physician knowledge, attitudes and treatment practices. Design. Randomized controlled trial. Setting. Louisville and the surrounding central Kentucky region. Participants. Twenty-four pediatricians in clinical practice. Interventions. A distance learning program for pediatric asthma consisting of Web- or CD-ROM–based multimedia learning modules and two teleconference calls. Outcome Measures. Learner satisfaction and change in physician asthma knowledge, attitudes, and treatment behavior at 1 to 4 months (short term) and 6 to 8 months (long term). Results. Pediatricians had graduated from medical school a mean of 11.6 years before baseline (SD ±8.9); 56% were female. On all learner satisfaction items, the average score was a 4.0 or greater on a 5-point scale, indicating a favorable response from the participants. Participants in the education group reported increased familiarity with asthma guideline for prescribing daily-inhaled corticosteroids compared to control physicians (p = .03) at short-term follow-up. Participants also expressed increased confidence in selecting a medicine for patients requiring a low-dose inhaled steroid (p = .03). However, these differences were not seen at long-term follow-up. Compared to the control group, there was no significant increase in the proportion of patients receiving inhaled steroids for persistent asthma at short- or long-term follow-up. Conclusions. Pediatricians utilizing an asthma distance learning program expressed a high degree of learner satisfaction. The program was associated with a temporary increase in familiarity and confidence in implementing components of the asthma guidelines.
