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

open access: yesESC Heart Failure, Volume 8, Issue 4, Page 2690-2697, August 2021., 2021
Abstract 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.

The LENT index predicts 30 day outcomes following hospitalization for heart failure

open access: yesESC Heart Failure, Volume 8, Issue 1, Page 518-526, February 2021., 2021
Abstract Aims The LE index (Length of hospitalization plus number of Emergent visits ≤6 months) predicts 30 day all‐cause readmission or death following hospitalization for heart failure (HF). We combined N‐terminal pro‐B type natriuretic peptide (NT‐proBNP) levels with the LE index to derive and validate the LENT index for risk prediction at the point

[Retracted] Multiobjective Optimal Dispatching Method of Generalized Power Active Distribution Network Based on Game Theory

open access: yesSecurity and Communication Networks, Volume 2021, Issue 1, 2021., 2021
To improve the operating dependability of a generalized power active distribution network, a multiobjective optimal scheduling approach based on game theory is proposed. The active distribution network′s multistakeholder coordinated and optimal dispatching mode is then established, and the game interaction between various stakeholders in the ...
