OBJECTIVE: Measuring immature white blood cell forms ("bands") has been considered clinically unnecessary. We performed this study to determine whether elevated band counts, with normal total white blood cells on admission, were associated with infection or in-hospital death.
METHODS: We performed a retrospective cohort study including all patients admitted to the Christiana Care Health System 2-hospital, 1100-bed community-based academic health system in 2009 with normal white blood cells (3800-10,800 per mm(3)) on admission who had manual differentials performed. We defined our band groups as normal (≤10% bands and other immature cells), moderate (11%-19%), or high (≥20%). Via chart review, we …
