Intracerebral hemorrhage (ICH) is associated with a high early mortality rate. We examined the impact of early do not resuscitate (DNR) orders and other limitations in aggressive care on mortality after ICH in a community-based study.
Cases of spontaneous ICH from 2000 to 2003 were identified from the Brain Attack Surveillance in Corpus Christi (BASIC) project, with deaths ascertained through 2005. Charts were reviewed for early (<24 hours from presentation) DNR orders, withdrawal of care, or deferral of other life sustaining interventions, analyzed together as combined DNR (C-DNR). Multivariable Cox-proportional hazards models were used to examine the association between short- and long-term all-cause mortality and early C-DNR, adjusted for demographics and established predictors of mortality after ICH.
Of 18,393 subjects screened for cerebrovascular disease, 270 non-traumatic ICH cases were included. Cumulative mortality risk was 0.43 at 30 days and 0.55 over the study course. Early C-DNR was noted in 34% of cases and was associated with a doubling in the hazard of death both at 30 days (hazard ratio [HR] 2.17, 95% CI 1.38, 3.41) and at end of follow-up (HR 1.92, 95% CI 1.29, 2.87) despite adjustment for age, gender, ethnicity, Glasgow Coma Scale, ICH volume, intraventricular hemorrhage, and infratentorial hemorrhage.
Early care limitations are independently associated with both short- and long-term all-cause mortality after intracerebral hemorrhage (ICH) despite adjustment for expected predictors of ICH mortality. Physicians should carefully consider the effect of early limitations in aggressive care to avoid limiting care for patients who may survive their acute illness.
脑出血(ICH)与早期高死亡率相关。在一项基于社区的研究中,我们探讨了早期“不要复苏”(DNR)医嘱及积极治疗中的其他限制措施对脑出血后死亡率的影响。
从科珀斯克里斯蒂脑卒监测(BASIC)项目中确定2000年至2003年的自发性脑出血病例,并确定至2005年的死亡情况。回顾病历以查找早期(就诊后<24小时)DNR医嘱、停止治疗或推迟其他维持生命的干预措施,将其合并为综合DNR(C-DNR)进行分析。使用多变量Cox比例风险模型来检验短期和长期全因死亡率与早期C-DNR之间的关联,并对人口统计学因素和已确定的脑出血后死亡率预测因素进行校正。
在筛查的18393例脑血管疾病患者中,纳入了270例非创伤性脑出血病例。30天累计死亡风险为0.43,研究期间为0.55。34%的病例有早期C-DNR,且与30天(风险比[HR]2.17,95%CI 1.38,3.41)和随访结束时(HR 1.92,95%CI 1.29,2.87)死亡风险加倍相关,尽管对年龄、性别、种族、格拉斯哥昏迷量表、脑出血体积、脑室内出血和幕下出血进行了校正。
尽管对脑出血死亡率的预期预测因素进行了校正,但早期治疗限制仍与脑出血(ICH)后的短期和长期全因死亡率独立相关。医生应仔细考虑早期积极治疗限制的影响,以避免限制可能从急性疾病中存活的患者的治疗。
