Comparison of activities of daily living between participants with and without postoperative delirium.
| Overall (N=88) | Delirium (N=20) | Non-delirium (N=68) | P Value |
|---|---|---|---|
| Baseline ADLs (points), median ± IQR | 22 ± 11 | 15 ± 5 | 0.005 |
| Follow-up ADLs (points), median ± IQR | 40 ± 23 | 27 ± 17 | 0.002 |
| ADL declinea (points), median ± IQR | 16 ± 15 | 9 ± 15 | 0.037 |
| Proximal femoral nail (n=47) | Delirium (n=13) | Non-delirium (n=34) | P Value |
| Baseline ADLs (points), median ± IQR | 23 ± 10 | 15 ± 4 | 0.002 |
| Follow-up ADLs (points), median ± IQR | 43 ± 21 | 28 ± 16 | 0.001 |
| ADL declinea (points), median ± IQR | 18 ± 15 | 10 ± 12 | 0.041 |
| Hip replacement (n=37) | Delirium (n=6) | Non-delirium (n=31) | P Value |
| Baseline ADLs (points), median ± IQR | 20 ± 14 | 16 ± 7 | 0.432 |
| Follow-up ADLs (points), median ± IQR | 33 ± 24 | 27 ± 19 | 0.147 |
| ADL declinea (points), median ± IQR | 12 ± 13 | 7 ± 14 | 0.283 |
| Open reduction and internal fixation (n=4) | Delirium (n=1) | Non-delirium (n=3) | N/Ab |
a
ADL decline was calculated by using follow-up ADLs score minus baseline ADLs score, which indicated the decline of activities of daily living. The larger ADLs change score indicates the greater ADL decline.
b
There was only one in four participants who had developed postoperative delirium after open reduction and internal fixation surgery at the time of follow-up evaluation. Thus, we did not determine the association between postoperative delirium and the decline of ADL in these participants.
Statistically significant results are highlighted in bold. ADL, activities of daily living; IQR, interquartile range; N/A, not applicable.
