Background: Patient-controlled analgesia (PCA) has been
shown to ameliorate the clinical outcome and previous
studies investigating the use of patient-controlled analgesia
have incorporated the evaluation of patient satisfaction.
This study aims to evaluate the factors that influence
patient satisfaction on postoperative patient-controlled
analgesia at King Chulalongkorn Memorial Hospital
Objective: To evaluate the factors affecting patient
satisfaction on postoperative patient-controlled analgesia
(PCA) in a tertiary care center
Setting: Acute pain service at King Chulalongkorn
Memorial Hospital, 1500-bed tertiary hospital.
Research design: Prospective and descriptive study.
Patient: Patients over 18 years of age undergoing
elective and emergency surgery under anesthesia with
postoperative patient-controlled analgesia provided
under supervision and care of acute pain service at King
Chulalongkorn Memorial Hospital from October 2013 to
September 2014.
Methods: Verbal Numeric Rating Scale for pain intensity
and patient satisfaction score (0-10; 0=worst and 10=best)
for postoperative pain assessment of 280 patients were
recorded by acute pain staffs at 24th hour and end of
service. The data were statistically analyzed by SPSS
version 22. Categorical data and continuous data
were analyzed by Chi-square tests and unpaired t-test
respectively. Multiple logistic regression was also used.
P < 0.05 was considered statistically significant.
Results: At the end of the study, 85.4% of patients
reported satisfaction score ≥ 8. Factors associated with
good satisfaction score were lower VNRS, P= 0.006.
Odd ratio= 0.316 (95%CI=0.140-0.716) and absence of
vomiting, P= 0.003. Odd ratio=0.327 (95%CI=0.155-0.691)
Conclusion: The majority of the patients reported high
levels of satisfaction on postoperative patient-controlled
analgesia (PCA). Factors contributing to high satisfaction
were lower VNRS and absence of vomiting.
