Agreement between the decision-support tool recommendation and treating orthopedic surgeon’s decision (n = 72*). Blue indicates 46 instances of agreement between the decision-support tool recommendation and the surgeon’s decision and red indicates 26 disagreements. *The number of patients referred for surgical consultation of the 100 patients initially assessed by the APP. The moderate level of agreement between the APP decision and the decision-support tool recommendation was further reviewed to understand the reasoning for the decisions made. It was found that the patients’ preferences to undergo surgery and insisting to see an orthopedic surgeon for further review were found to be the most frequent reasons for referrals, along with patients’ refusal to undergo surgery or be assessed for surgery.

Blue indicates 59 instances of agreement between the decision-support tool recommendation and the APP decision and red indicates 6 disagreements. APP = advanced practice physiotherapist. *The number of patients who were not insisting on surgical consult or avoiding surgical consult.
