Assessment of the concordance between DN4 scores performed by the patient (self-assessment) or by the physician (hetero-assessment) to detect subacute neuropathic postoperative pain.

Our results suggest that self-assessment, carried out after brief training and using a simple tool, provides results comparable to those obtained by a specialist physician to diagnose symptoms of neuropathic pain. If the results of the current study are confirmed on a larger scale, self-assessment will help improve access to specialized chronic pain care by better orienting patients and opening up access to teleconsultations.
