Prevalence of persistent post-surgical pain in a tertiary care hospital of a developing country: A cross sectional survey
Background: Persistent post-surgical pain (PPP) is pain that lasts three months or more after a surgical procedure. Research has shown significant prevalence of PPP after many surgical procedures. However, little is known of its prevalence in Southeast Asian region.
Objective: To assess the prevalence and characteristics of PPP after total knee replacement (TKR) and total abdominal hysterectomy (TAH) at our tertiary care university hospital. Methods: Approval for this cross-sectional survey was granted by the Ethics Review Committee. Informed consent was obtained from patients scheduled for elective surgery. A designated pain nurse called the patient three months and one year after surgery and filled out a questionnaire.
Results: 201 patients were included, 119 (59.2%) after TAH, and 82 (40.8%) after TKR. Three months after surgery 28 (13.9%) patients reported pain, 15 post-TAH (12.6%) and 13 (15.8%) following TKR. Twenty (71.4%) complained of pain at the operative site, while 8 (28.6%) had pain in the surrounding area. Twenty-five patients had burning and throbbing pain while 3 patients reported stabbing pain. Average pain score was 2.63 ± 0.87. At one year, five (17.9%) patients reported pain with a score of 3 to 6. Two of these patients (1.7%) had undergone TAH, while three (3.7%) had TKR.
Conclusions: PPP was found in 12.6% of patients after TAH and 15.8% after TKR at three months and in 1.7% after TAH and 3.7% after TKR at one year. Thus, prevalence of PPP in our tertiary care hospital was found to be lower than that reported in the literature from other centres. Future multicentral research is recommended to get a more holistic picture about the prevalence and to probe the reasons for difference in prevalence observed in our study.
