Purpose: The aim of this study was to identify the factor that influence the satisfaction about using patient controlled analgesia of postoperative patients.


A descriptive design was selected for this study. The participants were abdominal surgery, limited to GS surgery, that included gastrectomy, colorectomy, lobectomy, pancreatectomy and so on. And the patients who received the patient controlled analgesia treatment after surgery. The type of the patient controlled analgesia are intravenous or epidural patient controlled analgesia. A total of 2724 patents were participated. The survey was conducted between May 2014 and August 2015 in severance hospital. Pain has been measure using the Numeric Pain Rating Scale. To estimate patient controlled analgesia consumption, researchers measured the patient controlled analgesiaresidual dose after removing patient controlled analgesia. The patient satisfaction of patient controlled analgesia was measured by Likert scale. Statistics analysis was conducted using SPSS 23.0 and STATA 13.0. Researchers used to ANOVA and chi-square to identify the impact factor of patient satisfaction. In addition, researchers used the generalized ordered logistic regression to investigate the factor influencing the patient satisfaction about using patient controlled analgesia.


Comparing of the patient satisfaction depending on passage of time, it was significantly decreased when the patients' pain was increased. In the 6 to 24 hours after surgery, the lower level group of satisfaction score was decreased satisfaction further than the higher level group. In the lower level group of satisfaction, the nausea and vomiting didn’t significantly affect the patient controlled analgesia satisfaction. However, in the higher level group of satisfaction, the nausea and vomiting were effect the patient satisfaction. In all groups, patient satisfaction is significantly decreased when the patient experienced dizziness and headache. The patient controlled analgesia consumption affected the patient satisfaction.

Conclusion: The postoperative patients pain management using the patient controlled analgesia is important to improve patient satisfaction. It would be able to contribute to affect the postoperative pain management resulting in patient satisfaction promotion.
