Prevalence and characteristics of medical and rehabilitation utilization among Canadians with arthritis from 2001 to 2018: a cross-sectional population-based study

Arthritis covers a range of chronic diseases presenting as joint pain and inflammation with prevalence of 20% in Canadians. Treatment guidelines for arthritis depend upon the type of arthritis but most include recommendations for rehabilitation interventions designed to optimize functioning and reduce disability. We set out to estimate the prevalence of healthcare utilization with different providers and to explore factors associated with utilization of different providers among Canadians with arthritis. This population-based study used Canadian Community Health Survey data (2001–2018) restricted to respondents with arthritis (≥12 years). We used self-reported consultation with healthcare providers (medical doctor, chiropractor, physiotherapist, nurse, psychologist) (2001–2010), and self-reported regular healthcare provider (2015–2018). We calculated the 12-month prevalence of utilization with providers, and used modified Poisson regression to assess predisposing (e.g. age, sex, education), enabling (e.g. income, province) and need (e.g. self-percieved health) factors associated with utilization of providers. From 2001–2010 and 2015–2018, respectively, prevalence of utilization of medical doctors was 92.0% (95%CI: 91.7–92.2%) and 91.0% (95%CI: 90.5–91.5%); chiropractors 13.1% (12.8–13.4%) and 9.6% (9.1–10.1%); physiotherapists 14.5% (14.1–14.8%) and 9.4% (8.9–9.9%); nurses 14.2% (13.9–14.5%) and 7.5% (7.2–7.9%); psychologists 3.0% (2.8–3.1%) and 3.9% (3.5–4.2%). Females were more likely to see any provider. Users of chiropractic care were less likely to be smokers and more physically active with greater utilization in the western provinces than in the east. Those with poorer self-perceived health were more likely to see physiotherapists, nurses and psychologists. Consultation with a nurse (2001–2010) was more likely in the northern territories, while regular care from a nurse (2015–2018) was more likely in older age groups. Canadians with arthritis were most likely to see medical doctors. Characteristics of healthcare utilizers varied by provider type. Geographical variation in utilization of chiropractors and physiotherapists likely related to differences by province and over time in what provincial health insurance covered while geographical variation in utilization of nurses was likely related to the lack of availability of medical doctors. Findings inform the need to strengthen healthcare delivery for Canadians, perhaps providing better access to providers of rehabilitation interventions.
