Derivation and validation of a two‐variable index to predict 30‐day outcomes following heart failure hospitalization

BACKGROUND: The LACE index-length of stay (L), acuity (A), Charlson co-morbidities (C), and emergent visits (E)-predicts 30-day outcomes following heart failure (HF) hospitalization but is complex to score. A simpler LE index (length of stay and emergent visits) could offer a practical advantage in point-of-care risk prediction. METHODS AND RESULTS: This was a sub-study of the patient-centred care transitions in HF (PACT-HF) multicentre trial. …
