The performance of ADLs under the ACE program was addressed in 3 RCTs.19, 20 and 21 Counsell and colleagues21 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 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. This difference in statistical significance may be due to sample sizes. Counsell and colleagues21 had a much larger sample size than Landefeld and colleagues19 and Covinsky and colleagues.20 Their sample demographics and method of data collection were similar.
