Does the Stability and Workload Index for Transfer score accurately predict unplanned ICU readmissions or unexpected death within 7 days of ICU discharge in a heterogeneous group of ICU patients?
The SWIFT score performed poorly in predicting unplanned ICU readmissions or unexpected death within 7 days of discharge in a heterogeneous ICU population.

OBJECTIVE: Unplanned readmission of hospitalized patients to an ICU is associated with an increased mortality and hospital length of stay. The ability to identify patients at risk, who would benefit from prolonged ICU treatment, is limited. The aim of this study is to validate a previously published numerical index named the Stability and Workload Index for Transfer in a heterogeneous group of ICU patients. DESIGN: In this retrospective data analysis, the Stability and Workload Index for Transfer score was calculated for all patients, and the ability of the score to predict readmission was compared with the original publication. SETTING: Four ICUs, one intermediate care unit, and one postanesthesia care unit of the department of anesthesia and intensive care of a university hospital. PATIENTS: All consecutive patients treated in one of the units. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Unplanned ICU readmissions or unexpected death within 7 days of ICU discharge. The data of 7,175 patients were included in the analysis. Five hundred ninety-six patients were readmitted or died within 7 days of discharge. The patients who are readmitted to the ICU are significantly older and have significantly higher scores that define the severity of disease at the time of admission and discharge of their first ICU stay. The source of admission for the initial ICU stay did not differ (p = 0.055), and the last Glasgow Coma Scale and the last PaO2/FIO2 ratio before discharge from the ICU were higher in patients who did not need a readmission to the ICU. The performance of the Stability and Workload Index for Transfer score is poor with an area under the receiver operator curve of 0.581 (95% CI, 0.556-0.605; p < 0.001). CONCLUSIONS: Based on the data from our patients, the proposed Stability and Workload Index for Transfer score by Gajic et al is not ideal in aiding the clinician in the decision, if a patient can be discharged safely from the ICU and further research is necessary to define the patients at risk for readmission.
Kastrup et al. (Thu,) conducted a cohort in ICU patients discharged to a general ward (n=7,175). Stability and Workload Index for Transfer (SWIFT) score was evaluated on Unplanned ICU readmissions or unexpected death within 7 days of ICU discharge (AUC 0.581, 95% CI 0.556-0.605, p=<0.001). The Stability and Workload Index for Transfer (SWIFT) score demonstrated poor predictive ability for unplanned ICU readmission or unexpected death within 7 days of discharge, with an AUC of 0.581.
