Then the investigators compare the results by internal and external benchmarking. Then suggest recommendations to improve the current situation of postoperative pain management.~parameters include Patient's data Pain assessments by using the visual analogue score of 11 point (from 0 no pain - 10 worst pain) will be evaluated as the following: Worst pain since surgery, Least pain since surgery, Pain score at rest. Pain score during movements in bed, Pain score during deep breathing and coughing, How often the severe pain since surgery (%), Does the pain interfere with sleeping pattern, and the side effects.
