Abstract

BACKGROUND

The application of mobile health (mHealth) platforms to monitor recovery in the postdischarge period has increased in recent years. Despite widespread enthusiasm for mHealth, few studies have evaluated the usability and user experience of mHealth in patients with surgical drainage.

OBJECTIVE

Our objectives were to (1) develop an image-based smartphone app, SurgCare, for postdrainage monitoring and (2) determine the feasibility and clinical value of the use of SurgCare by patients with drainage.

METHODS

We enrolled 80 patients with biliary or peritoneal drainage in this study. A total of 50 patients were assigned to the SurgCare group, who recorded drainage monitoring data with the smartphone app; and 30 patients who manually recorded the data were assigned to the conventional group. The patients continued to record data until drain removal. The primary aim was to validate feasibility for the user, which was defined as the proportion of patients using each element of the system. Moreover, the secondary aim was to evaluate the association of compliance with SurgCare and the occurrence of unexpected events.

RESULTS

The average submission duration was 14.98 days, and the overall daily submission rate was 84.2%. The average system usability scale was 83.7 (SD 3.5). This system met the definition of "definitely feasible" in 34 patients, "possibly feasible" in 10 patients, and "not feasible" in 3 patients. We found that the occurrence rates of complications in the SurgCare group and the conventional group were 6% and 26%, respectively, with statistically significant differences P=.03. The rate of unexpected hospital return was lower in the SurgCare group (6%) than in the conventional groups (26%) (P=.03).

CONCLUSIONS

Patients can learn to use a smartphone app for postdischarge drainage monitoring with high levels of user satisfaction. We also identified a high degree of compliance with app-based drainage-recording design features, which is an aspect of mHealth that can improve surgical care.

摘要

背景

近年来，移动医疗（mHealth）平台在出院后恢复期监测中的应用有所增加。尽管人们对 mHealth 普遍持热情态度，但很少有研究评估 mHealth 在有引流管的患者中的可用性和用户体验。

目的

我们的目标是（1）开发基于图像的智能手机应用程序 SurgCare，用于引流后监测，以及（2）确定患者使用 SurgCare 的可行性和临床价值。

方法

我们在这项研究中纳入了 80 名胆道或腹腔引流患者。共有 50 名患者被分配到 SurgCare 组，他们使用智能手机应用程序记录引流监测数据；30 名手动记录数据的患者被分配到常规组。患者继续记录数据，直到引流管移除。主要目的是验证患者使用该系统的各个元素的可行性，定义为使用系统的患者比例。此外，次要目的是评估 SurgCare 依从性与意外事件发生之间的关联。

结果

平均提交时间为 14.98 天，总体日提交率为 84.2%。平均系统可用性量表为 83.7（SD 3.5）。该系统在 34 名患者中符合“绝对可行”的定义，在 10 名患者中符合“可能可行”的定义，在 3 名患者中符合“不可行”的定义。我们发现，SurgCare 组和常规组并发症发生率分别为 6%和 26%，差异有统计学意义（P=.03）。SurgCare 组意外返院率（6%）低于常规组（26%）（P=.03）。
