All articles indexed in MEDLINE or CINAHL, related to the use of computer technology in patient education, and published in peer-reviewed journals between 1971 and 1998 were selected for review. Sixty-six articles, including 21 research-based reports, were identified.
Forty-five percent of the studies were related to the management of chronic disease. Thirteen studies described an improvement in knowledge scores or clinical outcomes when computer-based patient education was compared with traditional instruction. Additional articles examined patients' computer experience, socioeconomic status, race, and gender and found no significant differences when compared with program outcomes. Sixteen of the 21 research-based studies had effect sizes greater than 0.5, indicating a significant change in the described outcome when the study subjects participated in computer-based patient education.
The findings from this review support computer-based education as an effective strategy for transfer of knowledge and skill development for patients. The limited number of research studies (N = 21) points to the need for additional research. Recommendations for new studies include cost-benefit analysis and the impact of these new technologies on health outcomes over time.
