This study investigated the existence of racial differences in the survival of patients admitted to intensive care by family physicians and general internists for circulatory illnesses. The study population consisted of 249 consecutive patients admitted by these specialists to an ICU in a tertiary care hospital in Pitt County, North Carolina, during the June 1985 to June 1986 period. Logistic regression was used to specify the unique effect of race on ICU patient survival in-hospital, controlling for potential confounding factors such as disease severity, type of health insurance, and case mix. Black patients were almost three times more likely than white patients to die in-hospital following admission to the ICU (RR = 2.9, 95 percent I = 1.5, 5.6). Most of this difference in survival was explained by racial differences in disease severity.
本研究调查了家庭医生和普通内科医生收治的因循环系统疾病入住重症监护病房的患者在生存方面是否存在种族差异。研究对象为1985年6月至1986年6月期间,由这些专科医生连续收治到北卡罗来纳州皮特县一家三级护理医院重症监护病房的249名患者。采用逻辑回归分析来确定种族对重症监护病房患者院内生存的独特影响,并控制潜在的混杂因素,如疾病严重程度、医疗保险类型和病例组合。黑人患者入住重症监护病房后院内死亡的可能性几乎是白人患者的三倍(相对危险度=2.9,95%可信区间=1.5,5.6)。这种生存差异大部分可由疾病严重程度的种族差异来解释。
