1.2) Trajectories of Function in Self-care Activities of Daily Living (ADL): Baseline Through Hospital Discharge

Footnote:

Group 1: Discharged with Baseline Self-Care Activities of Daily Living (ADL) Function

Trajectory a: patients who had stable function throughout their course with no decline in self-care ADL function between baseline and admission and no decline between admission and discharge.

Trajectory b: patients who declined in self-care ADL function between baseline and hospital admission, but recovered to baseline self-care ADL function by the time of hospital discharge.

Group 2: Discharged with New or Additional Disability in self-care ADL (decline in self-care ADL function)

Trajectory c: Patients acquiring new or additional disability in self-care ADL between baseline and admission who did not recover to baseline function by the time of hospital discharge

Trajectory d: Patients who did not decline in self-care ADL function between baseline and admission but acquired new or additional disability in self-care ADL between admission and discharge.
