Real-world use of the sufentanil sublingual tablet system for patient-controlled management of acute postoperative pain: a prospective noninterventional study.

To evaluate the real-life effectiveness, safety, tolerability and patient-reported outcomes (PRO) of the sufentanil sublingual tablet system (SSTS) for postoperative pain management (POPM). This prospective, multicenter, noninterventional, study included adults with acute moderate to severe postoperative pain who self-administered sufentanil using the SSTS. Main outcome measures were pain intensity at rest (numerical rating scale [NRS]: 0 [no pain] to 10 [most intense pain imaginable]); most intense pain intensity (0-10); 4-point patient assessment of the pain control method ("excellent", "good", "fair", "poor"); patient satisfaction with the pain control level and the method of administration of pain medication (6-point scale: "extremely satisfied", "very satisfied", "satisfied", "dissatisfied", "very dissatisfied", "extremely dissatisfied").
