Description

Donze et al developed a score for identifying a patient at risk for a potentially avoidable hospital readmission within 30 days. This can help to identify a patient who may benefit from more aggressive management. The authors are from Brigham and Women’s Hospital and Bern University Hospital.


 

Patient selection: medical patient who is hospitalized

 

Outcome: 30-day readmission

 

Parameters:

(1) H for hemoglobin at discharge

(2) O for oncology service

(3) S for serum sodium at dischage

(4) P is for procedure during admission (any ICD-9-CM coded)

(5) IT is for index admission type

(6) A is for number of hospital admissions during past year

(7) L is for length of stay in days

total score =

= SUM(points for all 7 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 13

• The higher the score the greater the risk of a potentially avoidable readmission.
