The purpose of this study was to examine the between-mode equivalence and the relative efficiency of the 2 available modes of patient-reported outcome (PRO) data collection: a web-enabled touch screen tablet and a smartphone in a sample of patients who underwent foot and ankle orthopedic surgery.
A total of 136 patients who visited the clinic after foot/ankle surgery participated in the study. All patients completed the PRO questionnaire set using tablets at the hospital. After 24 hours of completing the first PRO questionnaire, the patients completed the same PRO questionnaire at home using their personal smartphones. The outcomes were statistically compared, and the patients' preferences were surveyed.
The intraclass correlation coefficients for comparing the results of PRO measurements between the 2 modes were 0.970 for the visual analog scale, 0.952 for the Foot Function Index, 0.959 for the foot and ankle outcome scale, and 0.957 for the patient's satisfaction. Sixty-eight participants (58.6%) responded that they were able to answer the questionnaires with more honesty at home using their smartphones. Regarding the mode, 60 participants (48.1%) responded that they have no preference between the devices.
The results of this study showed the equivalence of the 2 modes of PRO data collection: web-enabled touch screen tablets and smartphones. Smartphones may be the preferred mode of PRO measurement, due to their easy accessibility, increased privacy, and the patients' increased honesty in answering questionnaires.
本研究旨在考察两种可供选择的患者报告结局(PRO)数据采集模式(一种是带网络功能的触屏平板电脑,另一种是智能手机)之间的模式间等效性和相对效率,该研究对象为接受足踝矫形外科手术的患者。
共有 136 名在足踝手术后到诊所就诊的患者参与了本研究。所有患者均在医院使用平板电脑完成 PRO 问卷集。首次 PRO 问卷完成 24 小时后,患者在家中使用个人智能手机完成相同的 PRO 问卷。对结果进行了统计学比较,并对患者的偏好进行了调查。
两种模式下 PRO 测量结果的组内相关系数分别为:视觉模拟评分 0.970,足部功能指数 0.952,足踝结局评分 0.959,患者满意度 0.957。68 名参与者(58.6%)表示,他们在家中使用智能手机回答问卷时能够更加诚实地回答问题。关于模式,60 名参与者(48.1%)表示他们对两种设备没有偏好。
本研究结果表明,两种 PRO 数据采集模式(带网络功能的触屏平板电脑和智能手机)等效。由于智能手机易于访问、增加了隐私性,并且患者回答问卷时更加诚实,因此可能是 PRO 测量的首选模式。
