Numeric Rating Scale (NRS) for Pain
The Numeric Rating Scale (NRS) is the most widely used 0–10 pain intensity tool in perioperative care. Patients rate pain from 0 (no pain) to 10 (worst imaginable). Scores 1–3 (mild), 4–6 (moderate—requires analgesia), 7–10 (severe—urgent escalation). Essential for guiding analgesic titration and tracking treatment response postoperatively.
