The Brief Pain Inventory (BPI)

The Brief Pain Inventory (BPI) is a self-administered questionnaire to assess the severity of pain and the impact of pain on the patient's daily functions. The BPI gives two main scores: a pain severity score and a pain interference score. The pain severity score is calculated from the four items about pain intensity. Each item is rated from 0, no pain, to 10, pain as bad as you can imagine, and contributes with the same weight to the final score, ranging from 0 to 40. The pain interference score corresponds to the item on pain interference. The seven sub-items are rated from 0, does not interfere, to 10, completely interferes, and contributes with the same weight to the final score, ranging from 0 to 70.

Time frame: Up to postoperative day 90

The McGill Pain Questionnaire

The Short-Form McGill Pain Questionnaire-2 (SF-MPQ-2) is an expanded and revised version of the original Short-Form McGill Pain Questionnaire (SF-MPQ), developed to provide a rapid, yet comprehensive, assessment of the multidimensional experience of pain. The main component of the SF-MPQ-2 consists of 22 descriptors rated on a Numeric Rating Scale, ranging from 0 (very dissatisfied) to 10 (very satisfied).
