Physical therapy students’ application of an imaging decision rule for acute knee pain

ABSTRACT

Background

Evidence supports direct referral for imaging by physical therapists. Accuracy and self-efficacy for imaging decisions have not been investigated in entry-level doctor of physical therapy (DPT) students.

Objective

The purpose of this study was to understand the relationship between entry-level DPT instruction and accuracy and self-efficacy for imaging referral due to acute knee trauma. A second purpose was to identify relationships between accuracy and self-efficacy.

Methods

An online survey was sent via e-mail to program directors in accredited DPT programs in the United States with an invitation to forward the survey to DPT students. The survey captured demographic information and included five questions that assessed the respondent’s ability to apply the Ottawa Knee Rules (OKR). Self-efficacy was assessed using the Physiotherapist Student Self-Efficacy (PSE) questionnaire, a self-rated 5-point Likert scaled tool.

Results

Of 240 surveys, DPT students who completed imaging coursework had greater accuracy and higher self-efficacy (68.0% correct (95% CI, 63.6–72.5), PSE = 3.67, P < .001) compared to students who had not (45.8% correct (95% CI, 40.8–50.7), PSE = 2.67, P < .001). Conclusion: Accuracy by DPT students who completed imaging coursework was significantly improved and comparable to values from autonomous providers.
