Length of hospital stay after hip fracture and readmission rates of persons with and without Alzheimer's disease: a matched cohort study.

Persons with AD had shorter acute care hospital LOS, but had longer LOS in a community hospital setting compared to those without AD, which is similar to other findings when comparing total hospital LOS. These findings imply that short LOS in acute care hospitals may be associated with poor health outcomes for vulnerable older populations after hip fracture.
