Using a Novel Smart-Device Application for Follow-up After Percutaneous Coronary Intervention.

Smart-device applications offer a potential novel and accessible opportunity to follow-up patients undergoing percutaneous coronary intervention (PCI) and identify opportunities to improve care. To date, no studies have described patient follow-up through surveys administered with the use of smart-device applications. Through a large online personal health management record solution system (MyChart) and a complementary smart-device application, an electronic 26-item survey was administered to patients on their mobile device at 4 days, 1 month, 3 months, and 6 months after PCI at a single tertiary-care hospital from July 2017 to March 2018. Among the 112 participants, response rates at 4 days and 3-6 months after PCI were both 53%. Seventy-two percent of patients responded to at least 1 follow-up survey, and 25% patients responded at all 4 follow-up times. In responders, 68% had follow-up with cardiology/internal medicine at 30 days. At 3-6 months, 30% of patients reported persistent or recurrent symptoms, 19% had had a readmission for any cause, 54% were enrolled in cardiac rehabilitation, 25% were not on statin therapy, and 90% of patients who were working before PCI had returned to work. Post-PCI follow-up with the use of patient questionnaires through a smart-device application is feasible and a novel tool for improving quality of care.
