Cross-Correlation Among Visual Analog, Observational, and Behavioral Pain Scales of Oncological Patients Undergoing
Purpose:
To determine the perception of postoperative pain intensity between nurses and oncology patients undergoing major abdominal surgery.
Design:
A prospective cross-correlation study with 173 oncology patients undergoing major abdominal surgery, such as hepatectomy or pancreatectomy.
Methods:
Postoperative pain intensity was evaluated by clinical pain assessment tools such as critical-care pain observation tool (CPOT) and behavioral pain scale (BPS) recorded by the researcher, whereas the visual analog scale was completed by patients. Demographic and clinical data were recorded.
Findings:
The Cronbach's α for CPOT and BPS was α = 0.738 for each. There was a significant correlation between CPOT and BPS (ρ = 0.796, P < .001), whereas the visual analog scale was correlated with CPOT and BPS (ρ = 0.351, P < .001 and ρ = 0.352, P < .001, respectively), showing that nurses did not underestimate patients' pain levels.
Conclusions:
The management of postoperative pain intensity after major abdominal surgery requires clinical comprehension by nurses to achieve the reduction or suppression of pain.
