Effectiveness of Decision Aid in Men with Localized Prostate Cancer: a Multicenter Randomized Controlled Trial at Tertiary Referral Hospitals in an Asia Pacific Country

This study aims to evaluate the effectiveness of a PDA modified to the local context in improving patients ’ knowledge, decisional conflict, and preparation for decision making among men with localized prostate cancer. Sixty patients with localized prostate cancer were randomly assigned to control and intervention groups. A self-administered questionnaire, which evaluate the knowledge on prostate cance r (23 items), decisional conflict (10 items) and preparation for decision-making (10 items), was given to all participants at pre- and post-intervention. Data were analyzed using independentT test and pairedT test. The intervention group showed significant improvement in knowledge (p = 0.02) and decisional conflict (p = 0.01) from baseline. However, when compared between the control and intervention groups, there were no significant differences at baseline and post-intervention on knowledge, decisional conflict and preparation for decision-making. A PDA on treatment options of localized prostate cancer modif ied to the local context in an Asia Pacific country improved patients’ knowledge and decisional conflict but did not have significant impact on the preparation for decision-making. The study was also registered under the Australian New Zealand Clinical Trials Registry (ANZCTR), ACTRN12614000668606 registered on 25/06/2014.
