Computer services for patients. Description of systems and summary of findings

This article (1) describes a number of computer services provided to patients' homes, (2) summarizes four evaluation studies reported in this supplement, and (3) suggests direction for future research. The studies reviewed in this article suggest that computer services have little impact on patients' health status but a significant impact on use of services. Some computer services (eg, reminders) increase client visits and other services (eg, voice bulletin board) reduce clinic visits. The article suggests that a paradigm for conducting research on impact of home computer services on care of patients is missing and should be developed.
