Objective To explore the value of platelet-lymphocyte ratio (PLR) after return of spontaneous circulation (ROSC) combined with Sequential Organ Failure Assessment (SOFA) for estimating the short-term prognosis of ROSC patients suffered from in-hospital cardiac arrest (IHCA).Methods ROSC adult patients who suffered from IHCA during treatment in the Emergency Department of West China Hospital of Sichuan University between 00:00, August 1st, 2010 and 23:59, July 31st, 2018 were included retrospectively. The basic and clinical data of patients were collected. Patients were divided into survival group and death group according to the 28-day prognosis. Through logistic regression and receiver operating characteristic (ROC) curve analysis, the efficacy of PLR after ROSC combined with SOFA score in predicting the 28-day prognosis of IHCA patients was explored.Results A total of 199 patients were included, including 135 males and 64 females, with a mean age of (60.45±17.52) years old. There were 154 deaths and 45 survivors within 28 days. There were statistically significant differences between the survival group and the death group in terms of epinephrine dosage, SOFA score, proportion of patients complicated with respiratory diseases, and post-ROSC laboratory indexes including PLR, hemoglobin, red blood cell count, lymphocyte count, indirect bilirubin, serum albumin, cholesterol, and activated partial thrombin time (P<0.05). The result of multivariate logistic regression analysis showed that epinephrine dosage [odds ratio (OR)=1.177, 95% confidence interval (CI) (1.024, 1.352), P=0.022], SOFA score [OR=1.536, 95%CI (1.173, 2.010), P=0.002], PLR after ROSC [OR=1.011, 95%CI (1.004, 1.018), P=0.002] were independent risk factors for ROSC patients’ death on day 28. The areas under the ROC curve of epinephrine dosage, SOFA score and PLR after ROSC were 0.702, 0.703 and 0.737, respectively, to predict the patients’ 28-day outcome. Combining the epinephrine dosage and PLR after ROSC with SOFA score respectively to predict the 28-day outcome of patients, the areas under the ROC curve were 0.768 and 0.813, respectively.Conclusions The significant increase of PLR after ROSC is an independent risk factor for death within 28 days after ROSC. The combined application of PLR after ROSC and SOFA score in the 28-day outcome prediction of patients has better predictive efficacy.
