Development and Validation of a Screening Tool for Surgery-Specific Neuropathic Pain: Neuropathic Pain Scale for Postsurgical Patients.

Background: Despite the existence of several screening tools for neuropathic pain, none of these are specific to surgery. We have developed a simple questionnaire tool, the Neuropathic Pain scale for Postsurgical patients (NeuPPS), to measure neuropathic pain in postsurgical patients.

Objectives: The aim was to validate this tool in a breast cancer population using an item response theory model, resulting in an easy-to-use scale.
