Primary Outcome Measures

Name	Time	Method
The primary efficacy endpoint is defined as the daily average and maximum pain severity (numeric rating scale (NRS): 0 (no pain) - 10 (worst pain imaginable)) on the first postoperative day.<br>We want to use the so called QUIPS (quality improvement in postoperative pain management)-questionnaire for our data collection before and after introduction of the new analgesic concept. The questionnaire has been validated within a German wide benchmark project (so called QUIPS-project) and allows a comparison with other hospitals as well. Patients have to answer questions covering pain intensity, functional impairment, side effects of the medical condition or analgesic treatment and subjective global assessment. This is complemented by a part filled out by the attending physician covering relevant information about the patient, details about anaesthesia and surgery as well as analgesic score. <br>

Secondary Outcome Measures

Name	Time	Method
Secondary endpoints comprise analgesic score, treatment-related side effects, pain related functional impairment, peri- and postoperative complications and patient satisfaction. <br>Data collection is also planned using the QUIPS-questionnaire on the 1st postoperative day. <br><br>
