This study was based on the Kano model and rely on the Internet hospital to build a day surgery patient full-process nursing service platform. Based on the Internet hospital’s HIS system, nursing Yuanzhuo system, patient mobile terminal (WeChat) and other information systems. The platform was designed by following the WHO’s conceptual framework for developing a scaling-up strategy. It was tested and refined by a pilot in a hospital in China. The full-process care platform for day surgery patients realizes information interconnection and interoperability of patient surgical consultation, surgical inquiries, and postoperative follow-up. It consists of a WeChat applet (client) and an online website (server). Pre-experiment results show that patients are more likely to recommend the hospital’s day surgery to others. The mHealth-based perioperative full-process nursing service platform for day surgery patients can initially meet the health education needs, surgical consultation needs and follow-up needs of day surgery patients.
