NEWS scale score status, time to a discharge from a hospital or to a NEWS of ≤ 2 and maintained for 24 hours, whichever occurs first. NEWS score is based on 7 clinical parameters: respiration rate, oxygen saturation, supplemental oxygen, systolic blood pressure, pulse rate, level of consciousness, temperature. A score of 0, 1, 2, 3 is allocated to each parameter except supplemental oxygen (a score 0 or 1 is allocated) and level of consciousness (a score 0 or 3 is allocated). A higher score means the parameter is further from the normal range. All scores were summed to get an aggregate score. Aggregate score ranges from 0 to 19, with higher scores meaning higher risk. Low risk - aggregate score, 1-4 Low to medium risk - score 3 in any single parameter, Medium risk - aggregate score 5-6, High risk - aggregate score 7-19.
