Measuring Advanced/Extended Practice Roles in Arthritis and Musculoskeletal Care in Canada.

To our knowledge, no previous studies have assessed the workforce capacity or the perceived need for the training of ERPs working in arthritis and musculoskeletal care. Measurement is important because in these health disciplines, practitioners' scopes of practice evolve, and ERPs integrate into the Canadian health care system. ERPs have emerged to augment provision of arthritis care, but funding for continuing professional development opportunities and for role implementation remains tenuous.
