A Smartphone App for the Management of Postoperative Home Recovery After Thoracic Surgery Procedures: A Pilot Study Using the Care4Today™ App

<b>Background/Objectives:</b> In recent years, the use of smartphones has significantly increased among populations of almost every age. The aim of our work is to analyze the impact of an application (app) that follows up with the progress of a patient who underwent a thoracic surgery procedure in the first 30 days after discharge. <b>Methods:</b> We prospectively analyzed all the patients included in the pilot study from March 2023 to September 2023. The Care4Today™ app was downloaded and activated by the patient preoperatively. From the day of discharge, the app sent questions related to pain perception, breathing capacity, general clinical conditions, problems with surgical wound and quality of life. In the case of negative responses, clinical staff received an email with an orange (medium problem) or red (serious problem) alert. <b>Results:</b> Among the 96 patients who were included, 82 eventually downloaded and used the app. The mean age of the patients was 60.7 years (range 19-80), and 43 (52.4%) were female. Minimally invasive techniques (VATS or RATS) were used in 76 cases (92.7%). The mean length of in-hospital stay was 5.3 days. Malignancy was the reason for surgery in 66 cases (80.5%). The answer rate was 75.8%. A total of 698 orange alerts and 52 red alerts were sent by the app. Re-hospitalization was needed in two cases (only one case related to our surgical procedure). The app was globally judged as useful in the management of convalescence (with an average rating of 7.4 out of 10). Age was not related to the completion rate of answers. <b>Conclusions:</b> The use of the app Care4Today could prevent unexpected re-hospitalization and possible complications. The patients appreciated the use of this tool, and they found it useful for safer postoperative recovery. No difference according to the patients' age was found regarding the use of the app.
