Design outcomes

Primary

Measure	Time frame
Reduced Complication Rate: A decrease in the occurrence of complications among patients using the chatbot. Reduced Readmission Rate: Fewer hospital readmissions in the intervention group within 30 days post-CABG. Improved Patient Outcomes: Measured through lower Cardiac Post-Operative Morbidity Scores (C-POMS), showing the chatbot s impact on health improvements. Timepoint: Assessed at 7th , 14th, 21st and 30th days post-discharge (measured by the Cardiac Postoperative Morbidity Score [C-POMS] and clinical records).	—
