Low back pain (LBP) and neck pain (NP) account for as much as a third of all visits to outpatient physical therapy practices. 34,35 Despite providing this apparently high proportion of care, physical therapists rank third behind physicians and chiropractors in patient care-seeking rates among the major clinician types who provide care for patients with LBP, 7,8 with the majority of persons seeking care for LBP from a physician. 7,21,28 Deyo and Tsui Wu 21 found that 59% of all persons with LBP seek care from a physician. In ambulatory care medical settings, LBP ranks fifth among all diagnoses as a reason for a physician visit and second among symptomatic complaints for a physician visit, accounting for 2.3% to 2.8% of all visits to physicians. 20,28 After physicians, chiropractors are the next major provider group, accounting for a substantial proportion of care. 7,8,21 In chiropractic, 40% to 68% of all patients report LBP as the primary reason for seeking care and NP as the second most common reason. 17,30,40 Among these 3 major types of care providers for LBP and NP, physicians and chiropractors are similar because both provide primary care, while physical therapists and chiropractors are similar because both provide manipulative and corrective care. The conceptual and philosophical basis of care for physical therapists and chiropractors does differ, and 2 older studies conducted in the UK and Sweden indicate that chiropractors use more manipulation and physical therapists provide both manipulation and mobilization, as well as exercise, modality-based treatment, and education. 36,43 Variation in the attributes that determine care seeking for LBP has been docu-T T STUDY DESIGN: Secondary analysis of longitudinal population-based survey data.
T T OBJECTIVES:To investigate factors associated with care seeking for physician-referred physical therapy (MD/PT), as compared to physician-only (MD) or chiropractic-only (DC) care for spinal pain.
T T BACKGROUND:Although a large proportion of ambulatory physical therapy visits are related to spinal pain, physical therapists are not the most commonly seen provider. The majority of visits are to physicians, followed by chiropractors. We attempted to understand more about this disparity by examining social and demographic factors that differentiate between persons who see these providers.
T T METHODS:Episodes of care were constructed from participants in 2 panels from the Medical Expenditure Panel Survey who had spinal pain. The provider of care was identified for each episode, and logistic regression was used to determine factors associated with MD/PT use compared to MD use, and MD/PT use compared to DC use.
T T RESULTS:The majority of patients (61%) received MD care for spinal pain, followed by those who received DC (28%) and MD/PT (11%) care. Female sex, higher levels of education, and higher income were significantly associated with MD/ PT care over MD care. Increased age, female sex, lower self-health rating, and presence of at least 1 disability day were all significa...
