Observations ' 'shortly after the start of the COVID-19 pandemic in 2020 suggested that ibuprofen was ' 'associated with an increased risk of adverse events in COVID-19 patients, but subsequent ' 'observational studies failed to demonstrate increased risk and in one case showed reduced ' 'risk associated with NSAID ' 'use.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>A 38-center ' 'retrospective cohort study was performed that leveraged the harmonized, high-granularity ' 'electronic health record data of the National COVID Cohort Collaborative. A ' 'propensity-matched cohort of COVID-19 inpatients was constructed by matching cases (treated ' 'with NSAIDs) and controls (not treated) from 857,061 patients with COVID-19. The primary ' 'outcome of interest was COVID-19 severity in hospitalized patients, which was classified as: ' 'moderate, severe, or mortality/hospice. Secondary outcomes were acute kidney injury (AKI), ' 'extracorporeal membrane oxygenation (ECMO), invasive ventilation, and all-cause mortality at ' 'any time following COVID-19 ' 'diagnosis.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Logistic ' 'regression showed that NSAID use was not associated with increased COVID-19 severity (OR: ' '0.57 95% CI: 0.53-0.61). Analysis of secondary outcomes using logistic regression showed that ' 'NSAID use was not associated with increased risk of all-cause mortality (OR 0.51 95% CI: ' '0.47-0.56), invasive ventilation (OR: 0.59 95% CI: 0.55-0.64), AKI (OR: 0.67 95% CI: ' '0.63-0.72), or ECMO (OR: 0.51 95% CI: 0.36-0.7). In contrast, the odds ratios indicate ' 'reduced risk of these outcomes, but our quantitative bias analysis showed E-values of between ' '1.9 and 3.3 for these associations, indicating that comparatively weak or moderate confounder ' 'associations could explain away the observed ' 'associations.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>Study ' 'interpretation is limited by the observational design. Recording of NSAID use may have been ' 'incomplete. Our study demonstrates that NSAID use is not associated with increased COVID-19 ' 'severity, all-cause mortality, invasive ventilation, AKI, or ECMO in COVID-19 inpatients. A ' 'conservative interpretation in light of the quantitative bias analysis is that there is no ' 'evidence that NSAID use is associated with risk of increased severity or the other measured ' 'outcomes. Our findings are the largest EHR-based analysis of the effect of NSAIDs on outcome ' 'in COVID-19 patients to date. Our results confirm and extend analogous findings in previous ' 'observational studies using a large cohort of patients drawn from 38 centers in a nationally ' 'representative multicenter
