The National Early Warning Score 2 is based on the Modified Early Warning Score (MEWS) for Clinical Deterioration and the National Early Warning Score. It is a defined scoring system to aid clinical decision making of routinely recorded physiological data, and should be used with caution. Raised NEWS scores are associated with increased mortality of patients admitted as medical emergencies. This calculator is useful for triaging patients 16 years and older who may be at risk for deterioration and mortality. Do not use this calculator for children under the age of 16.

The National Early Warning Score 2 is calculated based on whether the patient’s respiratory rate, systolic blood pressure, heart rate, temperature, and conscious state, as well as whether the patient is or is not in hypercapnic respiratory failure, and has supplemental oxygen.

The Modified Early Warning Score calculators is a defined scoring system to aid clinical decision making of routinely recorded physiological data. The MEWS score is useful for triaging patients who may be at risk for deterioration and mortality. If the Modified Early Warning Score is 30% or higher, the patient will most likely be admitted to ICU or increased risk of death.

The score includes information on the patient’s systolic blood pressure, heart rate, temperature, respiratory rate, and conscious state.

The 4C Mortality Score for COVID-19 is a prognostic and risk stratification tool for patients admitted for COVID-19 based on a study performed by ISARIC WHO clinical characteristics protocol in the UK. The 4C Mortality Score is useful for triaging patients 18 years and older who may be at risk of death from COVID-19 during a hospital stay. This score reflects the clinical data available in most economically developed healthcare settings and has a methodological advantage over current COVID-19 prognostic scores such as its use of penalized regression methods, an event-to-variable ratio greater than 100 to reduce risk of overfitting, use of parameters commonly available at first assessment which increases its clinical applicability.

The 4C Mortality score uses patient demographics, clinical observation and blood parameters that are commonly available at the time of hospital admission, and can accurately characterize the patients at high risk of death in the hospital.

The COVID-GRAM Critical Illness Risk Score is based on the research by Liang W, et al for Clinical Risk Score Prediction of COVID-19, and was created to predict which patients with COVID-19 at the time of hospital admission will develop critical illness which is defined as a composite of admission to ICU, invasive ventilation, or death. The COVID-GRAM Critical Illness Risk Score is based on 10 of 72 commonly measured characteristics in COVID-19 patients at the time of hospital admission. Early detection of serious illness among hospitalized COVID-19 patients enables providers to take proactive measures in management.

The MuLBSTA Score predicts prognoses in hospitalized patients with viral pneumonia supposedly with greater accuracy than CURB-65. The MuLBSTA Score be used to accurately stratify hospitalized patients with viral pneumonia into relevant risk categories and could provide guidance to make further clinical decisions. This score study has not been fully reviewed/validated for use with COVID-19 patients at this time; use with caution in COVID-19 patients
