PMID 35090886WHAT IT FOUND
The FAMCAT assessment takes about 6 minutes and 24 items to score cognition, daily activity, and mobility in hospitalized patients.
It is much faster than fixed tests, but scores are less precise for patients with normal function.
Key findings
01The average test length was 24 items and took 5.94 minutes, compared to 19.4 minutes for a non-adaptive version.
02Measurement error was lowest for Mobility and Daily Activity but higher for Applied Cognition.
03The test was less efficient and precise for patients with higher (normal) function levels.

What it does not show
The study population was restricted to hospitalized patients with chronic conditions or surgical complications, so results may not apply to other settings. The test is less precise for patients with normal function levels, meaning it is better at detecting impairment than confirming intact ability. Applied Cognition scores had higher measurement error than the physical domains. The study describes the development and validation of the tool but does not test its impact on clinical outcomes or discharge decisions.
The easy way to misread this
Do not use FAMCAT scores to confirm that a patient has normal cognitive or physical function. The test is designed to detect impairment and has lower precision for patients with high function levels.
