Visaria et al used a simple count of cardiac comorbidities to predict readmission for a cardiovascular cause in a patient with heart failure. The authors are from Rutgers New Jersey Medical School and Weill Cornell Medicine.
Patient selection: heart failure patient being discharged from the hospital
Outcome: readmission for a cardiovascular cause
Comorbidities:
(1) presence of coronary artery disease
(2) atrial arrhythmia during index admission
(3) ventricular arrhythmia during index admission
The comorbidity count was the sum of the comorbidities present.
Interpretation:
• minimum count: 0
• maximum count: 3
