Baseline Characteristics on Skilled Nursing Facility (SNF) Admission (n = 24).
| Overall cohort n = 24 Median [interquartile range] |
Proportion of available data N(%) | |
|---|---|---|
| Age (median, IQR) | 83 [75–90] | 24 (100) |
| Female sex, n(%) | 17 (70.8) | 24 (100) |
| White race, n(%) | 23 (95.8) | 24 (100) |
| Elective hospitalization, n(%) | 5 (20.8) | 24 (100) |
| Hospitalization length of stay (days) | 5 [4–9] | 24 (100) |
| Living alone, n(%) | 17 (70.8) | 24 (100) |
| Baseline self-reported ADL dependency [0–7] | 0 [0–2] | 24 (100) |
| Baseline frailty index | 0.34 [0.21–0.44] | 24 (100) |
| Non-frail (FI ≤0.25) | 7 (29.2) | 7 (100) |
| Mild frailty (FI 0.26–0.35) | 6 (25.0) | 6 (100) |
| Moderate frailty (FI 0.36–0.45) | 6 (25.0) | 6 (100) |
| Severe frailty (FI >0.45) | 5 (20.8) | 5 (100) |
| SNF admission measurements | ||
| Delirium, n(%) | 4 (16.7) | 24 (100) |
| Number of dependent ADLs (0–7) | 5.0 [5.0–6.0] | 24 (100) |
| Modified barthel index | 57.0 [46.0–71.0] | 24 (100) |
| Grip strength (kg) | 13.7 [11.6–19.5] | 24 (100) |
| Gait speed (m/s) a | 0.4 [0.4–0.5] | 10 (41.7) |
Note. ADL = activities of daily living; FI = Frailty Index; SNF = skilled nursing facility. Baseline Frailty Index calculated from interview within 48 hours of admission based on self-reported comorbidities and functional ability 2 weeks prior to acute hospitalization, categorized by pre-established cutoffs. Hospitalization characteristics including length of stay measured from hospital discharge summary. ADL with a range of 0 to 7, with higher scores indicated more dependency.
