Abstract
Venous Thromboembolism (VTE) carries significant clinical implications, and with the rise in cannabis consumption, its potential influence on VTE outcomes warrants investigation. Using the National Inpatient Sample (NIS) database (2016–2019), we analyzed 2,217,184 hospitalized VTE patients. Among these, 1.8 % (38,810) reported cannabis use. We compared demographics, comorbidities, in-hospital outcomes, and quality metrics between cannabis users and non-users with VTE. Cannabis users were chiefly younger males (average age 45 in cannabis users vs. 62 in non-cannabis users) from lower-income brackets. Notably, 5.4 % discharged against medical advice. Although in-hospital mortality was initially lower for cannabis users (2.8 % vs. 5.1 %, OR 0.6, 95 % CI 0.69–0.94, p = 0.008), this difference became non-significant post-propensity-score matching (aOR 0.9, 95% CI 0.72–1.10, p = 0.3). Non-users faced higher in-hospital complications, a trend that persisted post-PSM. Among cannabis users, key mortality predictors were peripheral vascular disease, acute kidney injury, vasopressor use, cardiogenic shock, myocardial infarction, invasive ventilation, and surgical embolectomy. Cannabis users also had a shorter hospital stay (4.2 vs. 5.4 days) and slightly reduced costs ($27,472.95 vs. $31,660.75). The significantly younger age of VTE patients who use cannabis, coupled with the considerable proportion discharging against medical advice, underscores the urgency for tailored care interventions. Additional research is vital to comprehensively understand the interplay between cannabis consumption and VTE outcomes.
