Landefeld and colleagues19 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”21 between admission and discharge. There is a positive trend toward ADL improvement under the ACE program. Whereas Counsell and colleagues21 reported that differences in ADL performance were not statistically significant, Landefeld and colleagues19 and Covinsky and colleagues20 reported that differences in ADL performance were statistically significant.
