Prior to enrollment of patients, all physicians participated in an intervention which included the following elements: a brief seminar about medical management for children with asthma, introduction of protocols in low chart format (algorithms), use of a standardized progress note from for children with asthma, a series of computer-based simulations and individualized feedback to physicians. The effectiveness of the physician education component in changing physician behavior was measured by pre- /post-test, chart audit, and performance on computer-based simulations.
