We compared patterns of mortality among men with prostate cancer at 2 Department of Veterans Affairs (VA) and 2 private-sector hospitals in the Chicago area.
Mortality rates for 864 cases diagnosed between 1986 and 1990 were estimated using Cox proportional hazards models that incorporated age; income; cancer stage, differentiation, and treatments; and baseline comorbidity.
Race tended to associate with all-cause mortality irrespective of health care setting (Blacks vs Whites: hazard rate ratio [HRR] = 1.68 [95% confidence interval (CI) = 1.06, 2.67]; P <.001 in the private sector; HRR = 1.50 [95% CI = 0.94, 2.38]; P =.088 in the VA). However, comorbidity determined risk in the VA, whereas age and income predicted risk in the private sector.
Determinants of all-cause mortality in men with prostate cancer vary according to health care setting.
我们比较了芝加哥地区2家退伍军人事务部(VA)医院和2家私立医院中前列腺癌男性患者的死亡率模式。
使用Cox比例风险模型估计1986年至1990年间确诊的864例患者的死亡率,该模型纳入了年龄、收入、癌症分期、分化程度和治疗情况以及基线合并症。
无论医疗环境如何,种族都与全因死亡率相关(黑人与白人相比:风险率比[HRR]=1.68[95%置信区间(CI)=1.06,2.67];在私立部门P<.001;HRR=1.50[95%CI=0.94,2.38];在VA中P=.088)。然而,合并症决定了VA中的风险,而年龄和收入预测了私立部门中的风险。
前列腺癌男性患者全因死亡率的决定因素因医疗环境而异。
