Insights
A new Coronavirus Estimation Global (CORE-G) score was developed to predict in-hospital death in COVID-19 patients. This validated tool aids in early risk stratification for better patient outcomes during hospitalization.
Area of Science:
- Medical Informatics
- Epidemiology
- Clinical Medicine
Background:
- The COVID-19 pandemic necessitates effective tools for predicting patient mortality.
- Risk stratification models are crucial for identifying high-risk COVID-19 patients requiring intensive care.
- Existing models may not fully capture the complexity of in-hospital death predictors.
Purpose of the Study:
- To develop and validate a novel risk score system for predicting in-hospital death in COVID-19 patients.
- To establish an early identification method for COVID-19 patients at high risk of mortality.
- To create a practical tool for clinical use in managing COVID-19 patients.
Main Methods:
- A retrospective analysis of 821 COVID-19 patients from three centers.
- Patients were divided into developmental (n=411) and validation (n=410) cohorts.
- The Coronavirus Estimation Global (CORE-G) score was constructed using demographic, symptomatic, and laboratory variables.
Main Results:
- The CORE-G score incorporates 18 variables (5 demographic, 2 symptomatic, 11 laboratory).
- The model demonstrated good fit in both developmental (H=3.210, P=0.880) and validation (H=6.948, P=0.542) groups.
- High predictive performance was observed with AUCs of 0.955 (developmental) and 0.937 (validation), showing excellent sensitivity and specificity.
Conclusions:
- The CORE-G score effectively estimates the risk of in-hospital death for COVID-19 patients.
- This score represents a significant advancement towards clinical application for outcome prediction.
- The CORE-G score facilitates early identification and management of critically ill COVID-19 patients.
Objective:
Coronavirus disease 2019 (COVID-19) exists as a pandemic. Mortality during hospitalization is multifactorial, and there is urgent need for a risk stratification model to predict in-hospital death among COVID-19 patients. Here we aimed to construct a risk score system for early identification of COVID-19 patients at high probability of dying during in-hospital treatment.
Methods:
In this retrospective analysis, a total of 821 confirmed COVID-19 patients from 3 centers were assigned to developmental (n = 411, between January 14, 2020 and February 11, 2020) and validation (n = 410, between February 14, 2020 and March 13, 2020) groups. Based on demographic, symptomatic, and laboratory variables, a new Coronavirus estimation global (CORE-G) score for prediction of in-hospital death was established from the developmental group, and its performance was then evaluated in the validation group.
Results:
The CORE-G score consisted of 18 variables (5 demographics, 2 symptoms, and 11 laboratory measurements) with a sum of 69.5 points. Goodness-of-fit tests indicated that the model performed well in the developmental group (H = 3.210, P = 0.880), and it was well validated in the validation group (H = 6.948, P = 0.542). The areas under the receiver operating characteristic curves were 0.955 in the developmental group (sensitivity, 94.1%; specificity, 83.4%) and 0.937 in the validation group (sensitivity, 87.2%; specificity, 84.2%). The mortality rate was not significantly different between the developmental (n = 85,20.7%) and validation (n = 94, 22.9%, P = 0.608) groups.
Conclusions:
The CORE-G score provides an estimate of the risk of in-hospital death. This is the first step toward the clinical use of the CORE-G score for predicting outcome in COVID-19 patients.
