Abstract: Objective: To establish an "internet+" health education management mode based on mobile APP in lung cancer patients at day surgery ward in perioperative period. Methods: A total of 2885 patients with lung cancer who received thoracoscopic radical resection from a tertiary grade A hospital in Hangzhou were enrolled by convenience sampling from February to September 2022. Among them, 1324 patients from February to May 2022 were selected as control group with receiving the health education in routine way, and 1561 patients from June to September 2022 were selected as observation group with receiving the health education provided by APP. Patients' satisfaction, awareness rate of health education, cancellation rate of same-day operation and hospitalization were compared. Results: Cancellation rate of same-day operation of observation group was lower than that of control group (P<0.05). There were no statistically significant difference in patients' satisfaction, awareness rate of health education and hospitalzation cancellation rate between the two groups. Conclusion: "Internet+" health education mode for lung cancer patients at day surgery ward can benefits patients by providing comprehensive accurate health education from pre-admission to post-discharge.
