For two years an office computer was used to identify patients to prompt for opportunistic screening and call for systematic screening. After the two years 92% of patients on the list had had blood pressure readings recorded within the previous five years, of which 34% resulted from special prompts and 22% from screening letters. Those who failed to respond to letters were sent questionnaires, and their records were compared with those of screened patients. With the help of a microcomputer it is practicable to sustain a continuous screening rate of between 90% and 95%.
两年来，使用办公室电脑识别患者，以促使进行机会性筛查并要求进行系统性筛查。两年后，名单上92%的患者在过去五年内有血压读数记录，其中34%来自特殊提示，22%来自筛查信件。未回复信件的患者会收到问卷，其记录会与已筛查患者的记录进行比较。借助微型计算机，维持90%至95%的持续筛查率是可行的。
