PURPOSE We tested whether patients are more likely to pursue healthy behaviors (eg, physical activity, smoking cessation) if referred to a tailored Web site that provides valuable information for behavior change.
METHODS In a 9-month pre-post comparison with nonrandomized control practices, 6 family practices (4 intervention, 2 control) encouraged adults with unhealthy behaviors to visit the Web site. For patients from intervention practices, the Web site offered tailored health advice, a library of national and local resources, and printouts for clinicians. For patients from control practices, the Web site offered static information pages. Patient surveys assessed stage of change and health behaviors at baseline and follow-up (at 1 and 4 months), Web site use, and satisfaction.
RESULTS During the 9 months, 932 patients (4% of adults attending the practice) visited the Web site, and 273 completed the questionnaires. More than 50% wanted physician assistance with health behaviors. Stage of change advanced and health behaviors improved in both intervention and control groups. Intervention patients reported greater net improvements at 1 month, although the differences approached significance only for physical activity and readiness to change dietary fat intake. Patients expressed satisfaction with the Web site but wished it provided more detailed information and greater interactivity with clinicians.
CONCLUSIONS Clinicians face growing pressure to offer patients good information on health promotion and other health care topics. Referring patients to a well-designed Web site that offers access to the world’s best information is an appealing alternative to offering handouts or impromptu advice. Interactive Web sites can facilitate behavior change and can interface with electronic health records. Determining whether referral to an informative Web site improves health outcomes is a methodological challenge, but the larger question is whether information alone is sufficient to promote behavior change. Web sites are more likely to be effective as part of a suite of tools that incorporate personal assistance.
