Jo et al developed a model with nomogram for predicting the risk of readmission to the medical care unit (MICU). A patient at risk for readmission may benefit from more aggressive management. The authors are from
Patient selection: adult (>= 18 years of age) discharged from medical intensive care unit (MICU), intubated for > 48 hours (excluded if not intubated or if extubated within 48 hours)
Other exclusions: do not resuscitate order, admission following elective surgery, transfer to another ICU in the same hospital
Parameters:
(1) gender
(2) diabetes mellitus
(3) continuous renal replacement therapy (CRRT)
(4) white blood cell count on day of extubation per µL
(5) heart rate just before ICU discharge

= SUM(points for all 5 parameters)
Interpretation:
• minimum score: 0
• maximum score: 221.6
• The higher the score the greater the risk of readmission to the MICU.
