Background: Many patients in German hospitals complain of inadequate treatment of their postoperative pain. Hospital-related structural and procedural variables may affect pain perception and patient satisfaction. We studied the association of individual variables with outcome quality.
Methods: Data from the years 2011 to 2014 from the world's largest acute pain registry (QUIPS) were evaluated. The analysis was performed with mixed linear regression models.
Results: We studied registry data from 138 German hospitals concerning four commonly performed types of operations (total number of operations, 21 114) and found that the intensity of pain, functional impairment, and satisfaction with postoperative pain therapy were all highly variable from one hospital to another. Patients in university hospitals complained more often than those in standard care facilities of highly intense pain (odds ratio [OR] 2.44; 95% con - fidence interval [CI] [1.18; 5.04]) and dissatisfaction (OR 3.58 [1.85; 6.93]). In specialized centers as well, pain intensity (OR 1.39 [1.06; 1.83]) and dissatisfaction (OR 1.59 [1.25; 2.02]) were higher. Pain-related limitation of movement was also reported more commonly in university hospitals (OR 2.12 [0.87; 5.16]) and specialized centers (OR 1.87 [1.33; 2.65]) than in standard care facilities. Less pain-related limitation of movement and higher satisfaction were reported in hospitals in which pain was documented in the patients' charts and the patients felt adequately informed about the treatment options.
Conclusion: The current state of postoperative pain therapy leaves much room for improvement. Quality indicators in the field of acute pain medicine might help improve patient care.
