AbstractOBJECTIVE: Knowledge relevant to women's peri- and postmenopausal health decisions has been evolving rapidly. Web-based decision supports can be rapidly updated and have the potential to improve the quality of patients' decisions. We developed and tested a web-based decision support for peri- and postmenopausal health decisionmaking. METHODS: We recruited 409 women aged 45-75 for one randomized, controlled trial and 54 women with an upcoming clinic appointment for a subsequent trial. Women were randomized to use the web-based decision support versus a printed brochure (first trial) and usual care (second trial). Outcomes were changes in decisional satisfaction, decisional conflict, and knowledge, both within each trial and compared across the trials. RESULTS: Intervention subjects had greater increases in decisional satisfaction in the second trial and knowledge in both trials. A high dropout rate among women randomized to the website in the first trial effectively negated benefits in that trial, but not in the second. CONCLUSIONS: The utility of this web-based decision support in two trials depended on a number of factors that appear related to the urgency of making a decision. PRACTICE IMPLICATIONS: Decision aids should be targeted to patients actively trying to make a decision.
