The document discusses changes needed to implement a patient self-management system called MyCARDSS in cardiac rehabilitation clinics. It found that using MyCARDSS would increase the complexity of current workflows in three ways: (1) not all patients will use MyCARDSS, (2) it transfers tasks from professionals to patients, and (3) information in MyCARDSS must be synchronized with the electronic patient record system used by professionals. A generic workflow model was created and validated through interviews. It identified modifications required, such as patients filling out questionnaires via MyCARDSS instead of on paper. The goal is for MyCARDSS to advise patients on personal goals and interventions during and after rehabilitation.
