Long-term Use of Wearable Health Technology by Chronic Pain Patients

Objectives: People living with chronic pain may use wearable health technology (WHT) in conjunction with an expert-directed pain management program for up to 1 year. WHT use may be associated with improvements in key patient outcomes. Methods: A 12-month study of WHT use among people with chronic pain was conducted, consisting of iPhone and Apple Watch applications to measure movement, sleep, and self-reported pain. Clinical outcomes among 105 patients enrolled in a multidisciplinary pain program that included WHT use were compared with 146 patients in the same program but without WHT, and to 161 patients receiving medical pain management without WHT. Results: Participants used the WHT on average 143.0 (SD: 117.6) out of 365 days. Mixed-effects models revealed participants who used WHT had decreases in depression scores (-7.83, P<0.01) and prescribed morphine milligram equivalents (-21.55, P=0.04) over 1 year. Control groups also showed decreases in depression scores (-5.08, P=0.01; -5.68, P<0.01) and morphine milligram equivalents (-18.67, P=0.01; -10.99, ns). The estimated slope of change among the WHT was not statistically different than control groups. Discussion: Patients who used WHT as part of their pain management program demonstrated a willingness to do so for extended periods of time despite living with chronic pain and other comorbidities. Data trends suggest that WHT use may positively impact depression and prescribed medication. Additional research is warranted to investigate the potential of WHT to improve the negative consequences of chronic pain.
