A total of 366 patients from hospital A were used to identify predictors of 30-day HF (re-)hospitalization (HFH), which occurred in 88 (24.0%). Mean age was 76 years, 57% were male and 49% had ejection fraction below 40%. Age, eGFR, NT-proBNP, sodium, and haemoglobin were identified as predictors of HFH. The multivariable logistic regression model containing these factors had acceptable calibration and discrimination (AUC 0.73). The performance of the model was less favorable in the 127 patients from hospital B (29 patients with 30-day HFH), with AUC 0.65 and suboptimal calibration, indicating overestimation of risk. Doubling of NT-proBNP plasma levels and higher ambulatory oral loop diuretic dosages were strong predictors of mortality and HFH at 6 months in hospital A.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec004\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In patients with WHF receiving outpatient day-care intravenous diuretic treatment, age, eGFR, NT-proBNP, sodium and haemoglobin predicted 30-day HFH.
