Introduction:
The current pandemic with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has impacted healthcare around the globe. The CHADS2VASC and frailty scores have not been studied as tool predictors for outcomes in this population.
Hypothesis:
CHA2DS2VASC and frailty scores can be used as predictors of mortality and unfavorable outcomes in patients hospitalized with SARS-CoV-2 infection.
Methods:
We included patients ages 18 years and older who required in-hospital treatment for SARS-CoV-2 infection at a Community Hospital between February and April of 2020. CHA2DS2VASC score and frailty index (FI) were calculated at time of admission and were used as continuous variables in a multivariate logistic regression model. Cardiovascular (CV) outcome was a composite variable that included non-fatal MI, decompensated heart failure, unstable arrhythmia and CVA.
Results:
Amongst 109 patients, 55% were male, mean age was 61.7 years (standard deviation 17.7) and 73% of the patients were admitted from home. 21.1% (23) of the patients died during their stay. The mean CHA2DS2VASC score was 2.5 (SD 1.7). For every point increase in the CHA2DS2VASC score the odds of mortality increased by 78% (aOR 1.78; 95% CI; 1.07-2.97). The mean frailty score was 6.2 (SD 5.7). For every point increase in the frailty score the odds of mortality increased by 22% (aOR: 1.22; 95% CI 1.07-1.39) [Figure]. There was a trend between higher CHA2DS2VASC and frailty scores with worse CV outcomes during hospital stay but this did not meet statistical significance (aOR: 1.31; 95% CI 0.86-2.0, aOR: 1.04; CI 0.93-1.17 respectively).
Conclusions:
Higher CHA2DS2VASC and frailty scores are associated with increased risk of mortality. Although statistical significance was not reached for predicting CV outcomes, this was likely related to a small sample size. CHA2DS2VASC and frailty scores are a readily available and novel tool that can be used to predict mortality in hospitalized patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
