Physicians often miss opportunities to improve the quality of care for their patients hospitalized with HF because they do not calibrate HF therapy to a patients risk for adverse outcomes.

Patients hospitalized with heart failure (HF) provide a unique setting for the validation of such prognostic information collection. The Get With The Guidelines--HF (GWTG-HF) programs validated risk score has the potential to influence the quality of care provided to patients hospitalized with HF by informing decision making through routinely collected clinical data.

Objective The purpose of this study was to derive and validate a predictive model for in-hospital mortality using readily available clinical data in patients with HF admitted to a GWTG-HF hospital. Peterson et al. Circulation: Cardiovascular Quality and Outcomes. 2010;3:25-32

5. © 2010, American Heart Association. All rights reserved. Methods Between January 2005 and June 2007, data were collected from a cohort of 39,783 patients admitted to 198 GWTG-HF participating hospitals. Potential predictor variables included demo- graphics, co-morbidities, admission laboratory information, vital signs at presentation, and LV systolic dysfunction of 40%. Peterson et al.

6. © 2010, American Heart Association. All rights reserved. Results In-hospital death occurred in 1139 (2.86%) patients. Those who died were more likely to have a prior HF diagnosis and an LVEF < 40%, atrial fibrillation, CAD, COPD, anemia and renal insufficiency, higher heart rates, serum creatinine and BUN levels and lower blood pressure, serum sodium and hemoglobin levels on admission, but less likely to have hypertension, hyperlipidemia, or diabetes. Age, systolic blood pressure, BUN level, serum sodium, and heart rate on admission, non--Black race and the presence of COPD were independent predictors of in-hospital death. No significant interactions between left ventricular systolic function and coexisting illnesses were present, indicating that the impact of individual risk factors on outcome was consistent regardless of left ventricular function.

Conclusions Age, systolic blood pressure, and BUN level are the admission variables most predictive of in-hospital mortality, with admission heart rate, serum sodium, presence of COPD, and non--Black race contributing modestly. The validated GWTG-HF risk score uses routinely collected data to predict the risk of in-hospital mortality for patients hospitalized with HF. Application of the risk score derived from routine clinical factors collected at the time of admission could influence the quality of care provided to patients hospitalized with HF by informing clinical decision making.
