Value of NEWS and MEWS during discharge on prediction of readmission to ICU

Abstract

Failure to identify acute physiological deteriorations in malignant disease and inadequacy with them can increase the disease, worsen the disease and mortality. Therefore, introducing and reviewing the effectiveness of scoring criteria for deterioration is a special feature that MEWS and NEWS are two of these criteria. Because MEWS and NEWS are commonly used in the hospital, they should be used, if more accurate information is available, if other physiological variables apply them, and under what conditions most of them are present. Methods and Materials: All patients who were candidates for discharge from the ICU of Shohada Hospital and General Imam Reza from 12/1/98 to 13/1 in 4100 people were included in this study. Information and NEWs and MEWS scores were recorded before ICU registration. Clinical status was monitored and recorded 24 and 72 hours after examination in the ICU. The primary outcome included patient deterioration. Statistical analysis was performed using Spss Ver 22 software. P <0.05 was considered as a statistically significant level. Results: The mean scores of NEWS and MEWS index in fatal patients were 1 and 2 points higher, respectively. The median score of the MEWS index was one unit higher in individuals with organ failure. But the NEWS index score did not differ between the two groups. A unit increase in the amount of the NEWS variable increases the probability of death by 2.5 times. A unit increase in the MEWS variable increases the probability of unplanned discharge by about 5.5 times. A unit increase in patients' age reduces the probability of unplanned discharge by about 0.9 times. The MEWS and NEWS criteria have a sensitivity of 0.8 and 0.88 and a specificity of 0.89 and 0.5, respectively, at the cut-off point of 3.5.
