The PDTK will be implemented and evaluated for patients admitted to and discharged from general medicine units. The RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework will be used to inform research questions and methods that guide implementation and evaluation. A pre-post study will be performed in which the primary outcome is analyzed as the proportion of patients with Patient Activation Measure (PAM) Levels 3 or 4 at discharge. Approximately 358 patients will be enrolled to provide adequate power to detect an improvement in the primary outcome from 72% to 84%. Quantitative and qualitative methods will be used to assess implementation, adoption, and use of the intervention.
