The AM-PAC is comprised of test items that cover a wide range of function--from "rolling over in bed" to "running 5 miles." Because test items are linked on a common scale, functional scores can be tracked across an entire episode of care as patients' functional ability changes and they move to different care settings. Users can select the format (computer-based or paper short-form) that is best suited for their clinical setting. The AM-PAC is sensitive to change in functional status and detects changes that may be missed by other outcome instruments.
