Abstract

OBJECTIVES

To assess whether sepsis-associated coagulopathy predicts hospital mortality.

DESIGN

Retrospective cohort study.

SETTING

One-thousand three-hundred beds urban academic medical center.

PATIENTS

Six-thousand one-hundred forty-eight consecutive patients hospitalized between January 1, 2010, and December 31, 2015.

INTERVENTIONS

Mild sepsis-associated coagulopathy was defined as an international normalized ratio greater than or equal to 1.2 and less than 1.4 plus platelet count less than or equal to 150,000/µL but greater than 100,000/µL; moderate sepsis-associated coagulopathy was defined with either an international normalized ratio greater than or equal to 1.4 but less than 1.6 or platelets less than or equal to 100,000/µL but greater than 80,000/µL; severe sepsis-associated coagulopathy was defined as an international normalized ratio greater than or equal to 1.6 and platelets less than or equal to 80,000/µL.

MEASUREMENTS AND MAIN RESULTS

Hospital mortality increased progressively from 25.4% in patients without sepsis-associated coagulopathy to 56.1% in patients with severe sepsis-associated coagulopathy. Similarly, duration of hospitalization and ICU care increased progressively as sepsis-associated coagulopathy severity increased. Multivariable analyses showed that the presence of sepsis-associated coagulopathy, as well as sepsis-associated coagulopathy severity, was independently associated with hospital mortality regardless of adjustments made for baseline patient characteristics, hospitalization variables, and the sepsis-associated coagulopathy-cancer interaction. Odds ratios ranged from 1.33 to 2.14 for the presence of sepsis-associated coagulopathy and from 1.18 to 1.51 for sepsis-associated coagulopathy severity for predicting hospital mortality (p < 0.001 for all comparisons).

CONCLUSIONS

The presence of sepsis-associated coagulopathy identifies a group of patients with sepsis at higher risk for mortality. Furthermore, there is an incremental risk of mortality as the severity of sepsis-associated coagulopathy increases.

摘要

目的

评估脓毒症相关凝血障碍是否可预测住院死亡率。

设计

回顾性队列研究。

地点

一家拥有 1300 张病床的城市学术医疗中心。

患者

2010 年 1 月 1 日至 2015 年 12 月 31 日连续收治的 6148 例患者。

干预

轻度脓毒症相关凝血障碍定义为国际标准化比值（INR）≥1.2 且＜1.4 并伴有血小板计数≤150000/µL 但＞100000/µL；中度脓毒症相关凝血障碍定义为 INR≥1.4 但＜1.6 或血小板计数≤100000/µL 但＞80000/µL；重度脓毒症相关凝血障碍定义为 INR≥1.6 且血小板计数≤80000/µL。

测量和主要结果

未发生脓毒症相关凝血障碍患者的住院死亡率为 25.4%，而发生重度脓毒症相关凝血障碍患者的住院死亡率为 56.1%，死亡率逐渐升高。同样，随着脓毒症相关凝血障碍严重程度的增加，住院时间和 ICU 治疗时间也逐渐增加。多变量分析显示，无论对患者基线特征、住院变量和脓毒症相关凝血障碍-癌症相互作用进行何种调整，脓毒症相关凝血障碍的存在以及严重程度均与住院死亡率独立相关。脓毒症相关凝血障碍存在的比值比（OR）范围为 1.33 至 2.14，脓毒症相关凝血障碍严重程度的 OR 范围为 1.18 至 1.51（所有比较的 p＜0.001）。
