Key result
A National Early Warning Score (NEWS-d) >7.5 at ICU discharge identified the risk of readmission within 48 hours with 98% sensitivity and 95% specificity.
Why the study?
The study aimed to identify patients who will require readmission to the intensive care unit based on their National Early Warning Score at discharge.
Does the National Early Warning Score (NEWS-d) at discharge predict readmission to the ICU within 48 hours in adult patients?

Does the National Early Warning Score (NEWS-d) at discharge predict readmission to the ICU within 48 hours in adult patients?
Effect estimate: Sensitivity 98%, Specificity 95%
A NEWS-d value >7.5 at ICU discharge is highly sensitive and specific for predicting ICU readmission within 48 hours.
Highlights substantial post-ICU readmission burden; leaves open NEWS-d utility for prediction pending prospective validation.
Backround/aim: To identify, at an early stage of intensive care, patients who will require readmission to the intensive care unit (ICU) based on their National Early Warning Score (NEWS-d) at discharge. Materials and methods: Overall, 536 patients aged >18 years who stayed at a tertiary ICU for >24 h were included. Patients who readmitted and not readmitted to the intensive care within 48 h after discharge were compared. Results: Mean patient age was 64.26 ± 18.50 years and 252 (44.7%) patients were male. Mean Acute Physiology and Chronic Health Evaluation II (APACHE II) score was 21.86 ± 8.74; mean NEWS-d was 4.48 ± 2.53. Forty-nine (9.1%) were readmitted to ICU. The reasons for initial admission, age, and NEWS-d vvalues were significantly different between the 2 groups. The NEWS-d values of the readmitted group were significantly higher (9.16 ± 1.05) than nonreadmitted group (4.01 ± 2.13). Based on receiver operation curve analysis, sensitivity and specificity were 98% and 95%, respectively, considering a NEWS-d cut-off value of 7.5 as the limit value for estimating readmission. Conclusion: A NEWS-d value of >7.5 demonstrated high sensitivity and specificity in identifying the risk of readmission for patients being discharged from ICU.

Doğu et al. (2020) conducted a cohort in Intensive care unit (ICU) readmission (n=536). National Early Warning Score (NEWS-d) at discharge vs. Nonreadmitted patients was evaluated on Readmission to the intensive care unit within 48 h after discharge (Sensitivity 98%, Specificity 95%). A National Early Warning Score (NEWS-d) >7.5 at ICU discharge identified the risk of readmission within 48 hours with 98% sensitivity and 95% specificity.
