Table 3. Total and cohort-specific differences in functional outcomes. The number of days from surgery to ambulation was similar between both cohorts. Patients in the CI cohort were more likely to be discharged to a SNF.
| Post-operative functional status | Cognitively impaired (n=57) | Non-impaired (n=25) | P value |
|---|---|---|---|
| Mean days from surgery-to-ambulation (days) | 1.50±0.91 | 1.76±1.09 | 0.30 |
| Number of feet walked on 1st ambulatory day (feet) | 95.08±124.32 | 131.64±111.55 | 0.19 |
| Number of feet walked on day of discharge (feet) | 166.60 ±141.68 | 214.20±138.10 | 0.16 |
| LOS (days) | 5.33±2.39 | 5.48±2.18 | 0.78 |
| Discharge to home (%) | 47.36 | 68.00 | 0.08 |
| Discharge to SNF (%) | 49.12 | 28.00 | 0.06 |
| Discharge to acute rehabilitation facility (%) | 3.50 | 4.00 | 0.91 |
| 30-day re-admission rate (%) | 12.80 | 12.00 | 0.73 |
