Abstract: Objective: To establish a clinical pain assessment and management system and evaluate its application effect, so as to provide a reference for standardized clinical pain assessment and management. Methods: The pain assessment and management system was established from the aspects of clinical pain assessment methods, management tools, quality evaluation and the closed-loop information management platform of pain score. Nurses' performance in pain assessment, patient pain control effect, and patient satisfaction were compared before and after the application of system. Results: After the application of the system, the completeness and accuracy of pain assessment improved (P<0.05), the proportion of intravenous analgesics decreased (P<0.05), the timely treatment rate for explosive or severe pain increased (P<0.05), and patients' satisfaction with pain control effectiveness increased (P<0.05). Conclusion: This system can objectively reflect the condition and treatment outcome of related painful diseases, laying a solid foundation for improving the overall pain assessment and management level and clinical diagnosis and treatment effect, and is worthy of further promotion.
