Pharmacological and Non-Pharmacological Postoperative Pain Management Practices Among Nurses in Vietnam: A...

Background/Objectives: Despite extensive research on nurses' knowledge and attitudes toward pain management globally, limited evidence exists regarding the actual implementation of multimodal pain management practices among Vietnamese nurses. This study aimed to (1) assess nurses' implementation of pharmacological and non-pharmacological postoperative pain management interventions, (2) examine the relationships among knowledge, attitude, and practice (KAP), and (3) identify predictors of competent practice with attention to the relative contributions of formal training versus clinical experience. Methods: A cross-sectional survey was conducted among 230 nurses working in Urology Departments from two tertiary public hospitals in Ho Chi Minh City, Vietnam, between April and June 2024, focusing on postoperative pain management. Pain management knowledge, attitudes, and practices were assessed using validated instruments. Independent samples t-tests compared trained versus untrained nurses. Multiple linear regression identified predictors of practice competency. Effect sizes (Cohen's d) quantified the magnitude of training effects. Results: Nurses demonstrated moderate-to-good competency, with pharmacological interventions (M = 3.74) implemented more consistently than non-pharmacological interventions (M = 3.48, p < 0.001). Trained nurses significantly outperformed untrained nurses across all domains with large effect sizes (Cohen's d = 1.34-1.54). A clear hierarchy emerged in non-pharmacological practice: environmental (M = 4.01) > physical (M = 3.69) > cognitive-behavioral (M = 3.27) > spiritual (M = 2.60). Strong KAP correlations were observed (r = 0.70-0.85, p < 0.001). Prior training was the strongest predictor of both pharmacological (β = 1.31, p < 0.001) and non-pharmacological practice (β = 0.58, p < 0.001), while clinical experience showed no significant effect (p > 0.40). Conclusions: This study provides evidence that formal training-not clinical experience-is strongly associated with competent postoperative pain management practice among Vietnamese nurses, with large effect sizes demonstrating practical significance. The strong KAP relationships support targeted educational interventions addressing knowledge gaps to improve practice. These findings have implications for nursing education research in Vietnam and similar healthcare settings.
