A videotape and lecture method for teaching the self-measurement of blood pressure were compared in twenty, 13- 18-year-old adolescents. The time of instruction and evaluation were monitored in order to assess acquisition of skills and cost-effectiveness. Both methods of instruction were equal in respect to acquisition of skills. The videotape method of instruction was more cost-effective than the lecture method in populations of more than 23.9 patients per year, as long as videotape equipment was already available. If the equipment needed to be purchased, the videotape method became more cost-effective with populations of greater than 93.6 patients per year. It was concluded that health care teams should consider the videotape method as a cost-effective means of instruction when videotape equipment is available. In addition, a health care team which evaluates and follows a substantial number of patients per year for hypertension could realize considerable savings in the use of the newer media.
在20名13至18岁的青少年中，对用于教授血压自我测量的录像带教学法和讲座教学法进行了比较。对教学和评估时间进行了监测，以评估技能的掌握情况和成本效益。两种教学方法在技能掌握方面效果相当。只要录像带设备已经具备，录像带教学法在每年超过23.9名患者的人群中比讲座教学法更具成本效益。如果需要购买设备，录像带教学法在每年超过93.6名患者的人群中成本效益更高。得出的结论是，当有录像带设备时，医疗团队应将录像带教学法视为一种具有成本效益的教学手段。此外，每年评估和跟踪大量高血压患者的医疗团队在使用新媒体方面可以节省可观的费用。
