ABSTRACT
The effectiveness of medication therapy can be influenced by a patient’s decision in the drug use process. A lack of knowledge about medication and therapy regimen might affect the therapeutic outcome. To support patients in the drug use process, an innovation instrument, namely Patient Decision Aid (PDA), is required. In this study, we aimed to explore the effectiveness of PDA in improving medication knowledge, helping patients in decision-making about their medication, and achieving good therapeutic outcomes. The study involved pre- and post-testing, comprising 25 patients at Rumah Diabetes at University of Surabaya. The results showed that there were significant improvements in patient medication knowledge and their blood glucose levels; however, no significant difference was observed in decision conflict. The provision of PDA successfully assisted in conveying information that was not provided by other health professionals. Furthermore, pharmacists may help patients optimize their medication and continuous follow-ups to evaluate therapeutic outcomes.
