Abstract
There are several treatment options for localized prostate cancer with very similar outcome but vary in terms of technique and side effect profiles and risks. Considering the potential difficulty in choosing the best treatment, a patient decision aid (PDA) is used to help patients in their decision-making process. However, the use and applicability of PDA in a country in Asia Pacific region like Malaysia is still unknown. 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 cancer (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 independentTtest and pairedTtest. 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 modified 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.
