In Response:
We agree with Dr. van Oostrom that it is ideal to have research data, or any confidential patient data, sent over the Internet in encrypted form. These data acquisition systems should also comply with any national laws protecting patients privacy (like the Health Insurance Portability and Accountability Act [HIPAA] in the United States). Kline et al. (1) implemented such a system successfully for a research project in the field of emergency medicine.
But we do not agree with Dr. van Oostroms statement that the system described in our paper would not be acceptable under HIPAA. The patients data were totally anonymous. The patients were identified only with consecutive numbers and the key was kept with the centers. The data sent over the Internet in an unsecured form consisted only of numbers (except of a few free text fields that were not violating the patients privacy) and the key was with the study centers also. If intercepted, the data would be absolutely useless for the interceptor. The information entered through the website could not identify any individual person, nor any of the data. Therefore, the system we built complied fully with HIPAA (2).
Although FrontPage (Microsoft, Redmond, WA) in general supports data encryption, the built-in functions (so called FrontPage extensions) do not work properly with SSL technique (this is information that can be found in various FrontPage support forums and on FAQ pages of web hosting companies). In addition, there is no possibility to have the data being sent by email in encrypted form with the FrontPage extensions. Further third-party products or extensive programming skills are necessary to accomplish a 100% secured and encrypted system with FrontPage. But if the research data are sent in coded form and no information identifying the patients is used, an effective, HIPAA-compliant and inexpensive Internet data collection system for research projects can be built as described in our article.
