Evaluation of the Edmonton Functional Assessment Tool (EFAT2) within palliative care: a pilot study

Background:
There is increasing need for rehabilitation in both cancer and palliative care. However, there are few validated outcome measures that are suitable for measuring functional performance in this population. The present study evaluated the validity, sensitivity and reliability of the Edmonton Functional Assessment Tool (EFAT2) within a UK palliative care setting.
Methods:
Eleven participants aged 65 years and over (mean age 76.5 ± 6.7 years) receiving rehabilitation in a palliative care inpatient setting were studied. Concurrent validity was assessed by comparing EFAT2 with the Barthel Index. Inter-rater reliability of EFAT2 was examined using a sample of four participants recruited from a cancer care ward.
Results:
A significant negative correlation was observed between the Barthel Index and EFAT2 (r = -0.765, p = 0.01) and both measures were found to be sensitive as determined by Cohen's effect size (EFAT2 = 0.60, Barthel Index = 0.72). High inter-rater reliability was noted for EFAT2 (ICC3, 1 = 0.85) and the agreement between scores was confirmed by Bland-Altman analysis.
Conclusions:
EFAT2 showed concurrent validity with the Barthel Index when used to assess the effects of rehabilitation on participants with advanced cancer. The tool was sensitive to change and was found to be reliable when used by different raters. The findings indicate that EFAT2 might be an appropriate outcome measure to use within the palliative care setting. However, the feasibility of using EFAT2 needs to be explored and larger studies are required to confirm its reliability.
