| Hip fracture hospital characteristics | |||
| # of hip fracture admissions/year, mean (SD) | 84.3 (55.0) | 84.7(54.9) | 83.8(55.2) |
| First PAC site after hospital discharge (%) | |||
| Inpatient rehabilitation facility (IRF) | 28.6 | 37 | 17.7 |

| Length of stay in first PAC setting in days | 26.3 (23.2) | 19.5(12.7) | 32.9(28.8) |
Note: Successful community discharge was defined as being discharged to the community from post-acute care and remaining in the community at least 30 days.
Not achieving successful community discharge included those patients that were still in a healthcare institution 90-days after hospital discharge, those who died before discharge to the community, and those who were discharged to the community but did not remain in the community at least 30 days.
SD= standard deviation
PAC=post-acute care
Occurrence of hospital complications during index hip fracture acute care stay includes: postoperative deep venous thrombosis and pulmonary embolism, postoperative myocardial infarction, or postoperative hemorrhage.
T-tests/Chi Square analysis comparing patients that achieved successful community discharge from those that did not achieve the outcome were all significant at P<0.001
