Abstract：
BACKGROUND: Life-sustaining treatment limitation (LSV) is the medical act of withdrawing or not initiating measures that are considered futile in a patient\'s specific situation. LSV in critically ill patients remains a difficult topic to study, due to the multitude of factors that condition it.
OBJECTIVE: To determine factors related to LSV in ICU in cases of post-ICU in-hospital mortality, as well as factors associated with survival after discharge from ICU.
METHODS: Retrospective longitudinal study.
UNASSIGNED: Intensive care unit of a tertiary hospital.
METHODS: People who died in the hospitalization ward after ICU treatment between January 2014 and December 2019.
METHODS: None. This is an observational study.
METHODS: Age, sex, probability of death, type of admission, LSV in ICU, oncological disease, dependence, invasive mechanical ventilation, emergency hemodialysis, transfusion of blood products, nosocomial infection (NI), pre-ICU, intra-ICU and post-ICU stays.
RESULTS: Of 114 patients who died outside the ICU, 49 had LSV registered in the ICU (42.98%). Age and stay prior to ICU admission were positively associated with LSV (OR 1,03 and 1,08, respectively). Patients without LSV had a higher post-ICU stay, while it was lower for male patients.
CONCLUSIONS: Our results support that LSV established within the ICU can avoid complications commonly associated with unnecessary prolongation of stay, such as NI.

摘要：
背景：维持生命治疗限制（LSV）是在患者的特定情况下撤回或不启动被认为是徒劳的措施的医学行为。重症患者的LSV仍然是一个很难研究的话题，由于条件的多种因素。
目的：确定ICU住院后死亡病例中与LSV相关的因素，以及与ICU出院后生存相关的因素。
方法：回顾性纵向研究。
■三级医院的重症监护病房。
方法：2014年1月至2019年12月在ICU治疗后在住院病房死亡的人。
方法：无。这是一项观察性研究。
方法：年龄，性别,死亡概率,录取类型,ICU中的LSV，肿瘤疾病,依赖，有创机械通气，紧急血液透析,输血,医院感染（NI），ICU前,ICU内和ICU后住院。
结果：在ICU外死亡的114名患者中，49例LSV在ICU登记(42.98%)。入住ICU前的年龄和住院时间与LSV呈正相关（分别为OR1,03y1,08）。没有LSV的患者ICU后住院时间较高，而男性患者则较低。
结论：我们的结果支持在ICU内建立的LSV可以避免通常与不必要的住院时间延长相关的并发症，比如NI。
