The Reliability of Remote PROMs via mobile applications to replace outpatient visits after surgery: Repetative test-retest comparison study for 1-years follow-ups after rotator cuff repair
ABSTRACT
Background:
With the development of healthcare-related mobile applications, attempts have been made to implement remote patient-reported outcome measures (PROMs). However, there are no studies have assessed the reliability of PROMs performed remotely using mobile applications compared with PROMs performed in outpatient visits.
Objective:
The purpose of this study were to evaluate the reliability of remote PROMs using mobile applications compared to PROMs performed during outpatient follow-up visits after arthroscopic shoulder surgery.
Methods:
A total of 174 patients who underwent arthroscopic rotator cuff repair completed questionnaires 2 days before visiting the clinic (test A). And the patients completed the questionnaires at the clinic (test B) using same mobile application and device for the 1-, 2-, 3-, 6-, and 12-month follow-ups. Test-retest comparisons were performed to analyze the differences and reliability of the PROMs according to the period.
Results:
Comparisons of tests A and B showed statistically significant differences at 1, 2, and 3-months (P<.05) but not 6 and 12 months after surgery (P >.05). The intraclass correlation (ICC) values between the two groups were relatively low at the 1-, 2-, and 3-month follow-ups but were within the reliable range at 6 and 12 months after surgery.
Conclusions:
PROMs using mobile applications with different locations differed soon after surgery but were reliably similar after 6 months. Remote PROMs using mobile applications are sufficient to be an alternative to outpatient visits for follows-ups over 6 months.
