Background: Prior reports indicate that modulation of the endocannabinoid system (ECS) may have a protective benefit for Covid-19 patients. However, associations between cannabis use (CU) or CU not in remission (active cannabis use (ACU)), and Covid-19-related outcomes among hospitalized patients is unknown. Methods: In this multicenter retrospective observational cohort analysis of adults (≥ 18 years-old) identified from 2020 National Inpatient Sample database, we utilize multivariable regression analyses and propensity score matching analysis (PSM) to analyze trends and outcomes among Covid-19-related hospitalizations with CU and without CU (N-CU) for primary outcome of interest: Covid-19-related mortality; and secondary outcomes: Covid-19-related hospitalization, mechanical ventilation (MV), and acute pulmonary embolism (PE) compared to all-cause admissions; for CU vs N-CU; and for ACU vs N-ACU. Results: There were 1,698,560 Covid-19-related hospitalizations which were associated with higher mortality (13.44% vs 2.53%, p ≤ 0.001) and worse secondary outcomes generally. Among all-cause hospitalizations, 1.56% of CU and 6.29% of N-CU were hospitalized with Covid-19 (p ≤ 0.001). ACU was associated with lower odds of MV, PE, and death among the Covid-19 population. On PSM, ACU(N(unweighted) = 2,382) was associated with 83.97% lower odds of death compared to others(N(unweighted) = 282,085) (2.77% vs 3.95%, respectively; aOR:0.16, [0.10–0.25], p ≤ 0.001). Conclusions: These findings suggest that the ECS may represent a viable target for modulation of Covid-19. Additional studies are needed to further explore these findings. Key points: Question: Is cannabis use associated with adverse Covid-19-related outcomes among hospitalized patients? Findings: History of cannabis use was associated with significantly lower odds of Covid-19-related hospitalization, mechanical ventilation, and death compared to those without history of cannabis use. Meaning: Our study findings suggest that the endocannabinoid system may represent a viable target for modulation of moderate and severe Covid-19 disease (Covid-19). Additional prospective studies are needed to further explore these findings. [ABSTRACT FROM AUTHOR] |
