From: Intensive care unit versus high-dependency care unit for patients with acute heart failure: a nationwide propensity score-matched cohort study

Length of hospital stay, days 27 ± 26 28 ± 27  − 0.9 (− 2.9 to 1.0) 0.33
Length of ICU/HDU stay, days 5 ± 7 5 ± 7  − 0.9 (− 1.4 to − 0.5)  < 0.001
Total hospitalization cost, USD 14,501 (17,070) 12,584 (11,462) 1916 (918 to 2914)  < 0.001
Complications after admission
