Abstract
Background: The ability to stand up from a chair is fundamental to functional independence.
Aim: To determine the clinical characteristics associated with the inability to stand from sitting in patients hospitalised with an AECOPD;to determine whether this is associated with increased risk of early readmission and mortality.
Methods: Measurements were made in 213 patients hospitalised with AECOPD at hospital discharge. Readmission and death were recorded at 30 days.
Results: Baseline characteristics:mean age 73,FEV135%pred,52% male. 89(42%) patients were unable to stand from sitting. The characteristics of patients stratified by ability to stand from sitting are shown in Table1. Those unable to stand were older, had reduced muscle strength, greater impairment in health status and respiratory disability, but similar FEV1 to those able to stand. Higher rates of hospital readmission (22.5%vs11.3%;Χ²p=0.028) and mortality (7.9%vs1.6%;Χ²p=0.025) were observed at 30 days in those unable to stand from sitting.

Conclusions: Inability to stand from sitting in hospitalised patients with AECOPD at discharge can identify patients with significant deficits in muscle strength, health status and physical performance, and is associated with increased risk of readmission and mortality.
