Optimal rehabilitation programs for orthopedic joint replacement patients ensure faster return to function, earlier discharge from hospital, and improved patient satisfaction. Digital health interventions show promise as a supporting tool for re-enablement.
The main goal of this mixed methods study was to examine the usability of the AIMS platform from the perspectives of both patients and clinicians. The aim of this study was to evaluate a re-enablement platform that we have developed that uses a holistic systems approach to address the de-enablement that occurs in hospitalized inpatients, with the older adult population most at risk. The Active and Independent Management System (AIMS) platform is anticipated to deliver improved patient participation in recovery and self-management through education and the ability to track rehabilitation progression in hospital and after patient discharge.
Two well-known instruments were used to measure usability: the System Usability Scale (SUS) with 10 items and, for finer granularity, the User Experience Questionnaire (UEQ) with 26 items. In all, 26 physiotherapists and health care professionals evaluated the AIMS clinical portal; and 44 patients in hospital for total knee replacement, total hip replacement, or dynamic hip screw implant evaluated the AIMS app.
For the AIMS clinical portal, the mean SUS score obtained was 82.88 (SD 13.07, median 86.25), which would be considered good/excellent according to a validated adjective rating scale. For the UEQ, the means of the normalized scores (range -3 to +3) were as follows: attractiveness=2.683 (SD 0.100), perspicuity=2.775 (SD 0.150), efficiency=2.775 (SD 0.130), dependability=2.300 (SD 0.080), stimulation=1.950 (SD 0.120), and novelty=1.625 (SD 0.090). All dimensions were thus classed as excellent against the benchmarks, confirming the results from the SUS questionnaire. For the AIMS app, the mean SUS score obtained was 74.41 (SD 10.26), with a median of 77.50, which would be considered good according to the aforementioned adjective rating scale. For the UEQ, the means of the normalized scores were as follows: attractiveness=2.733 (SD 0.070), perspicuity=2.900 (SD 0.060), efficiency=2.800 (SD 0.090), dependability=2.425 (SD 0.060), stimulation=2.200 (SD 0.010), and novelty=1.450 (0.260). All dimensions were thus classed as excellent against the benchmarks (with the exception of novelty, which was classed as good), providing slightly better results than the SUS questionnaire.
The study has shown that both the AIMS clinical portal and the AIMS app have good to excellent usability scores, and the platform provides a solid foundation for the next phase of research, which will involve evaluating the effectiveness of the platform in improving patient outcomes after total knee replacement, total hip replacement, or dynamic hip screw.
骨科关节置换患者的最佳康复计划可确保更快地恢复功能、更早出院并提高患者满意度。数字健康干预措施有望成为重新赋能的辅助工具。
本混合方法研究的主要目标是从患者和临床医生的角度检查 AIMS 平台的可用性。本研究旨在评估我们开发的一种重新赋能平台，该平台采用整体系统方法解决住院患者中出现的去赋能问题，而老年人风险最大。预计 Active and Independent Management System (AIMS) 平台将通过教育提高患者对康复的参与度和自我管理能力，并能够在医院和患者出院后跟踪康复进展。
使用两种著名的工具来衡量可用性：具有 10 个项目的系统可用性量表 (SUS)，以及用于更精细粒度的具有 26 个项目的用户体验问卷 (UEQ)。共有 26 名物理治疗师和医疗保健专业人员评估了 AIMS 临床门户；44 名接受全膝关节置换、全髋关节置换或动力髋螺钉植入术的住院患者评估了 AIMS 应用程序。
对于 AIMS 临床门户，获得的平均 SUS 得分为 82.88（SD 13.07，中位数 86.25），根据经过验证的形容词评分量表，这被认为是良好/优秀。对于 UEQ，归一化分数的平均值（范围为-3 到+3）如下：吸引力=2.683（SD 0.100），清晰度=2.775（SD 0.150），效率=2.775（SD 0.130），可靠性=2.300（SD 0.080），激励=1.950（SD 0.120），新颖性=1.625（SD 0.090）。所有维度均优于基准，与 SUS 问卷的结果一致。对于 AIMS 应用程序，获得的平均 SUS 得分为 74.41（SD 10.26），中位数为 77.50，根据上述形容词评分量表，这被认为是良好。对于 UEQ，归一化分数的平均值如下：吸引力=2.733（SD 0.070），清晰度=2.900（SD 0.060），效率=2.800（SD 0.090），可靠性=2.425（SD 0.060），激励=2.200（SD 0.010），新颖性=1.450（0.260）。所有维度均优于基准（新颖性除外，被评为良好），比 SUS 问卷提供了略好的结果。
该研究表明，AIMS 临床门户和 AIMS 应用程序都具有良好到优秀的可用性评分，该平台为下一阶段的研究奠定了坚实的基础，下一阶段的研究将评估该平台在改善全膝关节置换、全髋关节置换或动力髋螺钉后患者结局方面的有效性。
