We sought to examine the timing and referral patterns of patients with peripheral nerve injuries attending a multidisciplinary peripheral nerve clinic at a tertiary care centre.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;We conducted a retrospective, single-centre cohort study. We performed a chart review of all patients seen at a multidisciplinary peripheral nerve clinic at a tertiary care centre in Canada between 2017 and 2020.

The median time from injury to referral was 112 (interquartile range [IQR] 40 to 367) days. Sixty percent of patients had a delayed referral (&gt; 3 mo). After adjusting for potential confounding variables (injury level, mechanism of injury, and referral source), we found a 4% increased risk of experiencing a longer time from injury to referral for each unit increase in a patient's Rurality Index for Ontario score (adjusted rate ratio 1.04, 95% confidence interval 1.00 to 1.08).
