Content and retention evaluation of an audiovisual patient-education program on bronchodilators.
A study was conducted to: (1) evaluate the effect of a slide-tape program on patients' short-term and long-term knowledge about their bronchodilator medications; and (2) determine it any differences exist in learning or retention patterns for different content areas of drug information. The knowledge of 30 patients was measured using a randomized sequence of three comparable 15-question tests. The first test was given before the slide-tape program was presented, the second test within 24 hours, and the last test one to six months (mean = 2.8 months) later. Scores attained on the first posttest were significantly higher (p less than 0.001) than pretest scores. Learning differences among drug-information-content areas were not evidenced on the first posttest. No significant difference was demonstrated between scores on pretest and last posttest (p = 0.100). However, retention patterns among content areas were found to differ significantly (p less than 0.05). Carefully designed audiovisual programs can impart drug information to patients. Medication counseling should be repeated at appropriate opportunities because patients lose drug knowledge over time.
