Abstract
This study examined the association between physiotherapy utilization and subsequent medical healthcare utilization and costs in a population-based sample of adults with back pain in Ontario. We conducted a population-based cohort study of Ontario respondents with back pain (≥18 years) of the Canadian Community Health Survey 2003 to 2010 cycles, linked to health administrative data up to 2018. Physiotherapy utilization was defined as self-reported consultation with a physiotherapist in the past 12 months. A propensity score-matched cohort was conducted to match adults with and without physiotherapy utilization, accounting for potential confounders. We assessed associations using negative-binomial and linear (log-transformed) regression to evaluate outcomes of healthcare utilization (back pain-specific and all-cause) and costs, respectively, at 1- and 5-year follow-up. There were 4343 pairs of matched respondents. Compared with those who did not receive physiotherapy, adults who received physiotherapy were more likely to have back pain-specific physician visits (RR women (5years) = 1.48, 95% CI 1.24-1.75; RR men (5years) = 1.42, 95% CI 1.10-1.84). Women who received physiotherapy had 1.11 times the rate of all-cause physician visits (RR 1year = 1.11, 95% CI 1.02-1.20), and men who received physiotherapy had 0.84 times the rate of all-cause hospitalizations (RR 5years = 0.84, 95% CI 0.71-0.99) than those who did not. There was no association between physiotherapy utilization and healthcare costs. Adults with back pain who received physiotherapy are more likely to have back pain-specific physician visits up to 5-year follow-up than those who did not. Physiotherapy utilization is linked to some sex-based differences in all-cause healthcare utilization but not differences in costs. Findings inform interprofessional collaboration and allied healthcare delivery for back pain in Ontario.
