A videotape educational program was produced for use in adults with asthma. The program provided an overview of lung function, the physiologic abnormalities and treatment of asthma, and the approach to common problems encountered by the patients. Its benefits were examined in a randomized controlled study. The efficacy of the program in 62 patients whose mean duration of illness was 17 years was assessed by comparing the level of knowledge of the experimental group immediately after viewing the tape with that of the controls, who had not seen it; the experimental group scored significantly higher than the control group. Retention of knowledge attributed to the program was assessed after a mean interval of 16 months. The knowledge test score of the experimental group was found to have decreased to the level of the control group. The main areas in which the experimental group lost knowledge were self-care and drug therapy for asthma. The medical status of the two groups did not change appreciably over the period of the study.
制作了一盘录像带教育节目供成年哮喘患者使用。该节目概述了肺功能、哮喘的生理异常和治疗方法，以及患者遇到的常见问题的处理方法。在一项随机对照研究中对其益处进行了检验。通过比较观看录像带后实验组的知识水平与未观看录像带的对照组的知识水平，评估了该节目对62名平均病程为17年的患者的疗效；实验组的得分显著高于对照组。在平均间隔16个月后评估了该节目所带来的知识保留情况。发现实验组的知识测试得分已降至对照组的水平。实验组失去知识的主要领域是哮喘的自我护理和药物治疗。在研究期间，两组的医疗状况没有明显变化。
