Summary The data on the predictors and prognosis of acute liver injury (ALI) among patients in coronavirus disease 2019 (COVID‐19) patients are limited. The aim of this study was to determine the prevalence, predictors and outcomes of ALI among patients with COVID‐19. A systematic review was conducted up to 10 June 2021. The relevant papers were searched from PubMed, Embase, Cochrane and Web of Science, and the data were analysed using a Z test. A total of 1331 papers were identified and 16 papers consisting of 1254 COVID‐19 with ALI and 4999 COVID‐19 without ALI were analysed. The cumulative prevalence of ALI among patients with COVID‐19 was 22.8%. Male and having low lymphocyte levels were more likely to be associated with ALI compared with female and having higher lymphocyte level, odds ratio (OR): 2.70; 95% confidence interval (CI): 2.03, 3.60 and mean difference (MD) −125; 95% CI: −207, −43, respectively. COVID‐19 patients with ALI had higher risk of developing severe COVID‐19 compared with those without ALI (OR: 3.61; 95% CI: 2.60, 5.02). Our findings may serve as the additional evaluation for the management of ALI in COVID‐19 patients.
