High Patient Satisfaction with a Digital Care Platform After Thoracolumbar Spine Surgery: A Registry-Based Analysis

초록

Background/Objectives: SPINEHealthie is a smartphone-based application enabling remote patient monitoring, care delivery and standardized collection of patient-reported outcome measures (PROMs). This registry-based analysis evaluates patient satisfaction with the platform across a large, heterogeneous spine surgery cohort. Methods: A total of 1729 thoracolumbar spine surgery cases were eligible for analysis. Among these, 881 (50.9%) completed the in-app feedback survey and constituted the primary feedback cohort. The global app experience was categorized as "Very Good" or "Poor". Clinical outcomes, i.e., the Visual Analogue Scale (VAS) for back and leg pain and the Oswestry Disability Index (ODI) were assessed at baseline and in the postoperative period; Delta denotes the change from baseline to two weeks postoperation. Results: Among feedback responders, 800 patients (90.8%) rated their app experience as "Very Good", while 80.8% of 639 patients with surgical outcome data reported that the surgery met their expectations. However, app experience and surgical outcome expectations were assessed using different items at different postoperative time points. Among patients whose surgery did not meet expectations, 84.6% rated their app experience as "Very Good". Patients with a "Very Good" app-experience rating demonstrated significantly greater improvement in back pain (Delta VAS Back pain 2.94 vs. 2.13, p = 0.027), leg pain (Delta VAS Leg pain 3.16 vs. 2.14, p = 0.019) and disability (Delta ODI 11.00 vs. 2.41, p < 0.001). In the primary model, older age, shorter follow-up duration and smaller ODI improvement were associated with an unfavorable app experience; only the association with age remained consistent across sensitivity analyses. Conclusions: Among feedback responders, SPINEHealthie was associated with a high proportion of favorable global app-experience ratings. Favorable app-experience ratings remained high, even among patients with unmet surgical expectations or failure to achieve the exploratory two-week ODI-improvement threshold, suggesting that perceived platform value is not solely explained by surgical outcome. Older patients and those with limited functional recovery were identified as subgroups that may benefit from targeted onboarding and engagement strategies.
