The time taken to summarize 1000 patient records and store this data as a hard disc file on a microcomputer was evaluated in a health centre with about 7300 patients. On average it took 25 minutes to prepare or update summary sheets for each patient and between three to five minutes to input the data to the computer. About one in 10 of the records were long and complicated and took considerably more time to summarize. An error rate of 9% over six months was determined for the age-sex register, mostly owing to patients who had left the practice. In about 5% of cases important information was missing from the A4 folders and was only obtainable from the health visitor records.
在一家拥有约7300名患者的健康中心，评估了汇总1000份患者记录并将这些数据存储为微机硬盘文件所需的时间。平均而言，为每位患者准备或更新汇总表需要25分钟，将数据输入计算机需要3至5分钟。大约十分之一的记录冗长复杂，汇总起来需要更多时间。在六个月的时间里，年龄性别登记册的错误率为9%，主要是因为已经离开该诊所的患者。在大约5%的病例中，A4文件夹中缺少重要信息，只能从健康访视记录中获取。
