Validación externa de la escala Enhanced Feedback for Effective Cardiology Treatment (EFFECT) de predicción de mortalidad en pacientes que ingresan por insuficiencia cardiaca agudizada en Álava, España

Objective

To validate the EFFECT (Enhanced Feedback for Effective Cardiac Treatment) scales, which predict mortality at 1 month and 1 year after admission, in a defined cohort of patients admitted to the Araba University Hospital (HUA) with a diagnosis of acutely decompensated heart failure.

Method

External validation study of a predictive model, in a retrospective cohort of patients admitted between October 1, 2020 and September 30, 2021.

Results

A total of 550 patients were included. The two scales demonstrated good overall discriminatory ability in our series, with an area under ROC (0.755 y 0.756) and values in Brier score (0.094 y 0.194) similar to the original series. Calibration was assessed using the Hosmer-Lemeshow test and calibration plots and was also adequate. All this despite the fact that significant differences were observed in many clinical characteristics between our series and the original one.

Conclusions

The EFFECT scales showed good predictive ability and transportability. The one-month prediction scale was also useful for predicting mortality at one year. For both time periods, mortality was similar in the groups established in the original as low and very low risk.
