Medcast: evaluation of an intelligent pull technology to support the information needs of physicians.

This study reports the initial results of an evaluation of Medcast, a commercial medical information service that uses intelligent pull technology to deliver medical information to practicing physicians. Medical news, CME, and other information are transferred by modem nightly to the physician's computers where this information can be accessed at a convenient time. A survey was faxed to 195 subscribers to the system. A total of 73 (39%) responded. The results indicate that prior to implementation of the Medcast system, almost 40 percent of the respondents did not use their computers for professional activities because of time constraints, costs and computer literacy problems. After implementation of Medcast, almost 70 percent of the respondents used the system two or more hours per week. Ninety percent of the respondents felt that use of the system has enhanced their practice. These findings have important implications for future efforts to implement medical informatics applications to support the information needs of practicing physicians. Experience with intelligent pull technology that is relatively easy to use may be a good way to break down attitudes and barriers to the use of computer systems to support clinical practice and may prepare physicians for a wider use of the Internet to support their future information needs.
