To determine the reliability of clinical data collection and transmission by Internet in a multicenter primary care study.
Multicenter, observational study of a population of patients with exacerbated chronic obstructive pulmonary disease (COPD). All data were gathered in a specifically designed digital program on a palm-held pocket computer. Information was transmitted on-line by modem to a central database.
Thirty-nine researchers participated in this pilot phase. Over three months 324 patients were treated. Thirty-seven telephone consultations were generated, most (54%) in reference to how the digitized questionnaire worked. Questions were solved in a mean 5.44 minutes. No important technical problems occurred and no information was lost.
The use of the Internet to transfer data for multicentric studies in primary care is possible. This system should be more widely used in the future, as it allows faster data collection and eliminates the need to input data at the end of the study.
在一项多中心初级保健研究中，确定通过互联网进行临床数据收集和传输的可靠性。
对慢性阻塞性肺疾病（COPD）急性加重患者群体进行多中心观察性研究。所有数据均在掌上电脑上专门设计的数字程序中收集。信息通过调制解调器在线传输至中央数据库。
39名研究人员参与了该试点阶段。在三个月的时间里，共治疗了324名患者。产生了37次电话咨询，其中大部分（54%）是关于数字化问卷的使用方法。问题平均在5.44分钟内得到解决。未出现重大技术问题，也没有信息丢失。
在初级保健的多中心研究中，利用互联网传输数据是可行的。该系统未来应得到更广泛的应用，因为它能加快数据收集速度，并消除研究结束时输入数据的需求。
