IntroductionUnderstanding healthcare utilization by Canadians with back problems informs healthcare planning nationally. Research questionWhat is the prevalence of utilization of healthcare providers (medical doctors, chiropractors, physiotherapists, nurses), and associated characteristics among Canadians with chronic back problems (2001–2016)? Material and methodsThis population-based study used Canadian Community Health Survey data (2001–2016) restricted to respondents with chronic back problems (aged ≥12 years). We used self-reported consultation with healthcare providers (medical doctors, chiropractors, physiotherapists, nurses) from 2001–2010, and self-reported regular healthcare provider from 2015–2016. We calculated the 12-month prevalence of utilization with providers, and used modified Poisson regression to assess sociodemographic, health-related and behavioural factors associated with utilization of different providers. ResultsFrom 2001 to 2010 and 2015/2016, respectively, prevalence of utilization of medical doctors was 87.9% (95% CI 87.6–88.2) and 86.7% (95% CI 85.9–87.5); chiropractors 24.0% (95% CI 23.6–24.4) and 14.5% (95% CI 13.8–15.3); physiotherapists 17.2% (95% CI 16.9–17.6) and 10.7% (95% CI 10.0–11.4); nurses 14.0% (95% CI 13.7–14.2) and 6.6% (95% CI 6.1–7.0). Females were more likely to see any provider than males. Persons of lower socioeconomic status were less likely to consult chiropractors or physiotherapists (2001–2016), or nurses (2001–2010). Immigrants were less likely to consult chiropractors or nurses. Persons aged >65 years were less likely to consult chiropractors or physiotherapists, and those with fair/poor general health were less likely to consult chiropractors, but more likely to consult other providers. Discussion and conclusionMedical doctors were most commonly consulted by Canadians with back problems, then chiropractors and physiotherapists. Characteristics of healthcare utilization varied by provider. Findings inform the need to strengthen healthcare delivery for Canadians with back problems.
