Comorbidity profiles and pulmonary embolism risk assessment: Leveraging the Charlson Comorbidity Index for improved prognostication in a national data set.

ABSTRACT: Current risk assessment of pulmonary embolism (PE) stratifies patients based on hemodynamic stability, clinical parameters of severity, right ventricular dysfunction and cardiac injury but fails to integrate a wide variety of comorbid conditions. The Charlson Comorbidity Index (CCI) predicts mortality based on patients' diseases and provides a system to quantify disease burden. The National Inpatient Sample (NIS) database (2016-2018) was used to identify patients with PE and calculate CCI score groups of 0, 1-2, 3-5, and ≥6 and stratify them by outcome. Of 561,625 patients with PE, 176,460 (31.4%) had CCI score of 0, 223,870 (39.8%) had CCI of 1-2, 102,305 (18.2%) had CCI of 3-5, and 58,990 (10.5%) had CCI ≥ 6. Higher CCI scores were associated with increased mortality: CCI 1-2 (adjusted o
