Baseline Physiological Reserve Provides Greater Explanatory Value Than Discharge-Attained Strength Change for Early Postoperative Outcomes After Elective Abdominal Surgery.
BACKGROUND Acute perioperative handgrip strength change measured at discharge (Δacute) is often interpreted as a marker of vulnerability. However, it is discharge-anchored, influenced by peri-discharge conditions, and not measured at a standardized postoperative timepoint. We examined whether Δacute was independently a...
