Association of vasopressors with mortality in critically ill patients with COVID-19: A systematic review and meta-analysis
Abstract
Purpose
The effect of vasopressors on mortality of critically ill patients with COVID-19 has not been studied extensively.
Materials and Methods
A systematic search of PubMed, Scopus, and <ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://clinicaltrials.gov">clinicaltrials.gov</ext-link> was conducted for relevant articles until January 2022. Eligibility criteria were randomized controlled and non-randomized trials. The primary outcome was mortality at latest follow-up. The quality of studies was assessed using the MINORS tool. Paired meta-analysis was used to estimate the pooled risk ratios along with their 95% Confidence Interval.
Results
Analyses of 21 studies (n=7900) revealed that vasopressor use is associated with mortality in patients who receive vasopressors compared to those who do not receive vasopressor therapy [RR (95%CI): 4.26 (3.15, 5.76); p<0.001]. In-hospital and 30-day mortality are significantly higher in patients who receive vasopressors [RR (95%CI): 4.60 (2.47, 8.55); p<0.001 and RR (95%CI): 2.97 (1.72, 5.14); p<0.001, respectively]. The highest mortality rate was observed with vasopressin or epinephrine, while the lowest mortality rate was observed with angiotensin-II. Also, analyses of data from 10 studies (n=3519) revealed that vasopressor use is associated with acute kidney injury [RR (95%CI): 3.17 (2.21, 4.54); p<0.001].
Conclusion
Vasopressor use was associated with an increase in in-hospital mortality, 30-day mortality, and acute kidney injury in critically ill patients with COVID-19.
