Contact with the hospital is usually limited for patients after daycare surgery. Dedicated smartphone applications can improve communication and possibly enhance outcomes. The objective of this retrospective study was to evaluate patients’ self-reported pain and nausea and assess the success of routine implementation of a smartphone application for outcome reporting. During preoperative assessment, patients were instructed to download and activate the smartphone application to report pain, nausea and to be in contact with the hospital after discharge. Main outcome was the number of patients actively using the smartphone application and the incidence of pain and nausea on postoperative day 1 to 7. In total, 4952 patients were included in the study. A total of 592 (12%) participants downloaded the application, of whom 351 (7%) were active users. A total of 4360 (88%) participants refrained from downloading the application. 56% (2,769) were female, the median age was 46 (18-92), and 4286 (87%) were classified as 1 or 2 American Society of Anesthesiologists Physical Status (ASA). Postoperative pain was experienced by 174 (76%) of 229 active users on postoperative day (POD) 1 and decreased to 44 (44%) of 100 active users on POD7. Postoperative nausea was experienced by 63 (28%) of 229 active users on POD1 and decreased to 12 (12%) of 100 active users on POD7. Female sex (p .000), socioeconomic status (p .001), and surgical severity (p .001) showed statistically significant differences between active users, non-active users, and non-downloaders. Most patients active with the application experienced pain and nausea on the first and second day after discharge. Only a minority of the patients used the application. Those who used it were satisfied with the possibilities offered to them. Future research should focus on increasing the uptake and effect of this application on the quality of recovery.

日托手术后患者通过智能手机自我报告疼痛和恶心，第一年结果：一项观察性队列研究

日托手术后的患者与医院的联系通常受到限制。专用智能手机应用程序可以改善沟通并可能提高结果。这项回顾性研究的目的是评估患者自我报告的疼痛和恶心，并评估常规实施智能手机应用程序进行结果报告的成功程度。在术前评估期间，患者被指示下载并激活智能手机应用程序以报告疼痛、恶心并在出院后与医院联系。主要结果是积极使用智能手机应用程序的患者数量以及术后第 1 至 7 天疼痛和恶心的发生率。该研究总共包括 4952 名患者。共有 592 名（12%）参与者下载了该应用程序，其中 351 名（7%）是活跃用户。共有 4360 名（88%）参与者没有下载该应用程序。56% (2,769) 为女性，中位年龄为 46 岁 (18-92)，4286 (87%) 被美国麻醉医师协会身体状况 (ASA) 列为 1 或 2 级。在术后第一天 (POD)，229 名活跃用户中有 174 名 (76%) 经历了术后疼痛，而在术后第 7 天，100 名活跃用户中有 44 名 (44%) 经历了术后疼痛。在 POD1 的 229 名活跃用户中，有 63 名 (28%) 出现术后恶心，在 POD7 的 100 名活跃用户中，有 12 名 (12%) 出现术后恶心。活跃用户、非活跃用户和非下载者之间的女性性别 (p <.000)、社会经济地位 (p <.001) 和手术严重程度 (p <.001) 之间存在统计显着差异。大多数积极使用该应用程序的患者在出院后的第一天和第二天都会经历疼痛和恶心。只有少数患者使用该应用程序。使用它的人对为他们提供的可能性感到满意。未来的研究应侧重于提高该应用程序的使用率及其对恢复质量的影响。
