The performance of ADLs under the ACE program
was addressed in 3 RCTs Counsell
and colleagues reported that there was not a statistically
significant difference in ADL performance
from baseline to discharge between the
ACE intervention group and control group. Landefeld
and colleagues and Covinsky and colleagues,
20 using the same data set, reported that
patients from the ACE intervention unit were
‘‘more likely to improve and less likely to decline
in ADL performance’’ between admission and
discharge. There is a positive trend toward ADL
improvement under the ACE program. Whereas
Counsell and colleagues reported that differences
in ADL performance were not statistically
significant, Landefeld and colleagues and Covinsky
and colleagues reported that differences
in ADL performance were statistically significant.
This difference in statistical significance may be
due to sample sizes. Counsell and colleagues
had a much larger sample size than Landefeld
and colleagues and Covinsky and colleagues.
Their sample demographics and method of data
collection were similar.
