Interrater reliability for the Activity Measure for Post-Acute Care (AM-PAC) "6-Clicks" showed high overall agreement for basic mobility and daily activity scores. Agreement levels varied among rater pairs, indicating potential for tailored training.
Area of Science:
- Rehabilitation Medicine
- Health Services Research
- Clinical Assessment Tools
Background:
- The interrater reliability of the Activity Measure for Post-Acute Care (AM-PAC) "6-Clicks" for basic mobility and daily activity has not been established.
- Functional outcome measures are crucial for post-acute care patient assessment.
Purpose of the Study:
- To evaluate the interrater reliability of the AM-PAC "6-Clicks" basic mobility and daily activity measures.
- To provide evidence for the consistent application of these new functional assessment tools.
Main Methods:
- A prospective observational study design was employed.
- Physical and occupational therapist pairs rated patient functional mobility and daily activities across four hospital services.
- Intraclass correlation coefficients (ICCs), Bland-Altman plots, and weighted kappa statistics were used to assess reliability.
Main Results:
- Overall ICCs for basic mobility and daily activity were high (.849 and .783, respectively).
- Individual rater pair ICCs ranged from moderate to nearly perfect for both measures.
- Weighted kappa values indicated varying levels of item agreement, from small to very large.
Conclusions:
- The AM-PAC "6-Clicks" demonstrates strong overall interrater reliability for total scores.
- Agreement levels varied across rater pairs and individual items, suggesting areas for targeted training and quality improvement.
- These findings support the use of AM-PAC "6-Clicks" in post-acute care settings with attention to rater consistency.
