Table 3.
Proportion of People Who Changed FI by more than 0.03 Based on Level of CFS Change
| Baseline to Admission | CFS Change | N | N (%) Who Changed FI ≥ 0.03 |
|---|---|---|---|
| 0 | 1,534 | 356 (23.2%) | |
| +1 | 3,035 | 1,899 (62.6%) | |
| +2 | 1,013 | 890 (87.9%) | |
| +3 | 263 | 246 (93.5%) | |
| +4 | 79 | 78 (98.7%) | |
| Admission to Postdischarge | CFS Change | N | N (%) Who Changed FI ≤ −0.03 |
| 0 | 1,565 | 623 (39.8%) | |
| −1 | 1,819 | 1,215 (66.8%) | |
| −2 | 564 | 481 (85.3%) | |
| −3 | 130 | 115 (88.5%) | |
| −4 | 33 | 32 (97.0%) |
Note: CFS = Clinical Frailty Scale; FI = Frailty Index. CFS change = 0 indicates no change. Percentages reflect the proportion of n within each degree of CFS change whose FI changed by at least +0.03 (baseline to admission) or −0.03 (admission to postdischarge). CFS changes beyond ±4 are not reported due to small sample size.
