Hemoglobin on Admission and Clinical Outcomes

Hemoglobin (g/dL) No. (%) Death (n = 21) (%) Readmission (n = 93) (%) Mobility Score (n = 459) Length of Stay (days) (n = 549)
<9.0 16 (2.9) 3 (18.8) 6 (37.5) 4.8 16.4
9.0–9.9 26 (4.7) 2 (7.7) 6 (23.1) 5.8 7.8
10.0–10.9 67 (12.2) 4 (6.0) 11 (16.4) 7.0 9.5
11.0–11.9 113 (20.5) 4 (3.5) 23 (20.4) 5.9 8.3
≥12.0 328 (59.5) 8 (2.4) 47 (14.3) 6.8 8.2
P value 0.001 0.02 0.04 0.02

The initial hemoglobin was missing for one patient. P values for dichotomous outcomes are for a test for trend, and for the mobility score the Wilcoxon rank sum test.
