Poor quality communication during consultation between patient and doctor tends to be a doctor-centered. Patients tend to give less information about their concerns to their doctors during the consultation process. The purpose of the research is to investigate the critical criteria of patients with inflammatory bowel disease (IBD) in relation to their appointment for health treatment. Gut Caretaker is a self-management mobile application that enables IBD patients to take control of their lifestyle better by adding their appointment dates and test results, and tracking their symptoms based on a rule-based approach. User evaluation on unit testing is conducted and shows a positive result.
