VALID-CHF Prognostic Model (CardioWebdr)

VALID-CHF Prognostic Model — Explanation and Clinical Context This page implements a configurable template for the VALID-CHF prognostic model. The final prognostic estimate requires the original VALID-CHF model specification (either logistic regression coefficients or a validated point table). At present the template is prepared so you can paste model coefficients into the PHP array near the top of the file and the script will compute an individualized probability (via logistic transformation) automatically.

This approach preserves transparency (intercept and betas visible in code) and allows precise reproduction of the original publication’s formula. Clinical context: prognostic models in acute and chronic heart failure are used to estimate short-term (in-hospital or 30-day) and longer term (1–3 year) mortality risk, to assist triage, level-of-care decisions, and early counselling regarding prognosis. Common predictors across validated models include age, systolic blood pressure, admission heart rate, renal function / BUN, serum sodium, chronic pulmonary disease, and race.

For in-hospital mortality specifically, the Get With The Guidelines-Heart Failure (GWTG-HF) risk score (Peterson et al., Circ Cardiovasc Qual Outcomes 2010) is a widely validated comparator. If you can provide the VALID-CHF publication (DOI, PDF, or the model’s coefficient table / point mapping), I will immediately: (1) paste the exact coefficients into the scoeff` array, (2) convert any point-based scoring to the underlying probability formula if necessary, and (3) include the original paper reference and exact formula line in the page for traceability. Reference (example comparator): Peterson PN, Rumsfeld JS, Liang L, et al.

A validated risk score for in-hospital mortality in patients with heart failure from the American Heart Association Get With The Guidelines program. Circ Cardiovasc Qual Outcomes. 2010;3(1):25–32. doi:10.1161/CIRCOUTCOMES.109.854877.

Note on VALID-CHF publication search: I was unable to locate a peer-reviewed publication or DOI for a prognostic model titled “VALID-CHF” in PubMed, major HF registries, or common prognostic model repositories. Please supply the DOI or PDF and I will insert the exact model into this same template for maximal reproducibility and accuracy.
