N2 - Heart failure (HF) is characterized by frequent rehospitalization and prolonged hospital stay. Although length of stay has been used as a surrogate marker for hospital performance, its association with early rehospitalization remains unknown. We investigated their precise association using contemporary Japanese HF registry. We analyzed the 2785 acute HF patients who were registered in the West Tokyo Heart Failure registry and discharged or transferred to the recuperation facilities (mean age, 73.8 ± 13.5 years; 60.8% were men). Median length of stay was 15 days (interquartile range, 10–23 days). One-hundred and fourteen patients (4.1%) were readmitted for worsening HF within 30 days after discharge. Thirty-day risk-adjusted HF readmission after a shorter length of stay (1–12 days; the lower tertile within the cohort) was higher than those after intermediate (13–19 days; the middle tertile) [HR 1.71, 95% confidence interval (CI) 1.05–2.77]. Even after a longer length of stay, there tended to be a higher risk of 30-day HF readmission (HR 1.59, 95% CI 0.96–2.65). In conclusion, the Japanese acute HF patients had low rates of early-HF readmission after quite a long length of stay at urban tertiary care centers. Shorter length of stay was associated with increased rates of 30-day HF readmission, while longer length of stay also the same trended.
