Method: A prospective cohort of patients with clinically diagnosed neuropathy, were given the PD-Q at their clinic appointment or sent to them after their consultation. A score above 18 (out of 35) indicated NeP, and below 13 indicated no NeP. Results were analyzed using one-way analysis of variance (ANOVA), and Chi-square tests to evaluate possible associations between non-parametric variables.
Result: Eighty-nine patients (IANI = 56, LNI = 33) were included in the study. NeP was identified by PD-Q scores greater than 18 amongst 34% of 56 patients who reported experiencing pain. PD-Q scores less than 13 suggested that a quarter of patients were experiencing little or no symptoms of NeP, and 41% of patients had PD-Q scores between 13-18, which were inconclusive in confirming NeP.
Conclusion: PD-Q in its current format is not a suitable screening tool for NeP associated with IANI or LNI.
