摘要Objective:To investigate the quality of life (QOL) of cancer pain patients in Beijing,and explore the effect of cancer pain control on patients' QOL.Methods:Self-developed demographic questionnaire,numeric rating scale and SF-36 questionnaire were used together among 643 cancer pain patients in 28 Grade 2nd to 3rd general hospitals and 2 Grade 3rd cancer hospitals.Results:The SF-36 eight dimensions scores ranged from 31.75 to 57.22 in these cancer pain patients.The t test and Wilcoxon rank sum test were used to compare the QOL between pain controlled (PC) group and pain uncontrolled (PUC) group,and the results showed that patients in PC group had the higher QOL scores in 6 areas of SF-36 (P＜0.05).Binary logistic regression results found that pain management satisfaction scores (P＜0.001),family average personal monthly income (P=0.029),current receiving chemotherapy (P=0.009) and cancer stage (P＜0.001) were the predictors to cancer pain controlled results.Conclusion:Cancer patients with pain in Beijing had poor QOL.Pain control will improve the QOL of cancer pain patients.
