Abstract: Objective:To make a preliminary application of the assessment system for cancer pain management and find insuffi -ciency in the clinical practice of cancer pain diagnosis and treatment. Methods:Data from41doctor questionnaires, 43nurse question -naires, 50patient questionnaires, and 12ward questionnaires from the tumor departments of 3 hospitals were analyzed, and the insuffi-ciency in cancer pain management was determined. The wards in the tumor and non- tumor departments related to oncology were as -sessed using rank test, and differences between the 2 wards were investigated.Results:The average scores of doctor, nurse, and wards were 85.41± 5.93, 88.46± 5.09and 83.75± 3.11 , respectively, whereas patient score was 68.67± 7.14. To further analyze the patient subsys-tem by converting into a hundred-mark system, the effectiveness and safety scores for the pain management was 81.69± 7.71. However, patients' opinion score on pain treatment was only 55.78± 11 .37. The score of tumor departments was 82.22± 2.03, whereas related non-tumor departments had a score of 39.27± 3.58. Wilcoxon W value was at 120.0 with P<0.01after rank test. Conclusion:Education on patients' opinion on cancer pain management should be promoted in the tumor wards, and continuous education on cancer pain diagno-sis and treatment is needed in the non-tumor departments relative to oncology.
