Identifying physical therapists’ attitudes, beliefs, and barriers toward diagnostic imaging referral: a mixed-methods study

Abstract

ABSTRACT Objective Ten states, including the District of Columbia, have laws that currently permit physical therapists (PTs) to directly order diagnostic imaging (DI) in the United States. Military and civilian PTs order DI judiciously and appropriately demonstrating optimal patient outcomes and satisfaction when compared to other medical professionals. However, no studies have explored perceived attitudes, beliefs, and barriers to PT DI referral specific to North Dakota (ND). Therefore, the purpose of this mixed-methods study was to identify ND PTs’ attitudes, beliefs, and barriers toward DI referral. Methods A total of 147 participants completed an online survey with a subset of 17 participants agreeing to an interview. Frequency counts of demographic data and perceived barriers were completed. A binary logistic regression was run on demographic data. One-on-one interviews were conducted with a thematic coding process completed within a qualitative analysis. Results Seventy-four percent of PTs reported not currently referring for DI, although 71% felt that it would improve their patient outcomes. PTs with post-professional training (OR = 4.59), a doctorate degree (OR = 3.84), practicing in an orthopaedic or sports setting (OR = 3.55), and practicing within an urban setting of ND (OR = 3.01) were more likely to refer for DI. The main barriers identified in the survey included: (1) the logistics of performing a DI referral, (2) DI referrals only privileged to other medical providers, (3) provider/work relationship dynamics, (4) the cost of continuing education (CE), (5) and the inability to identify CE. One-on-one interviews further identified five main themes related to DI referral. Discussion/Conclusion Several barriers identified resulted in 74.1% of PTs not directly referring for DI, although certain characteristics (post-professional training, doctorate degree, orthopaedic/sports setting, practicing in an urban area in ND) were more likely to refer for DI. This study may help improve future adoption and implementation of DI referral in current and future states.
