Rising prevalence of venous thromboembolism in gastrointestinal cancers: a nationwide analysis of 205 million hospitalizations, 2016-2022.

Using the National Inpatient Sample (National Inpatient Sample) database from 2016 to 2022, we performed a cross-sectional analysis of 205,075,197 adult hospitalizations to quantify the prevalence and temporal trends of deep vein thrombosis, pulmonary embolism and venous thromboembolism in gastrointestinal cancer hospitalizations, and calculated the relative risk (RR) of venous thromboembolism and inpatient death (inpatient death) in GICs compared with all hospitalizations.
