Differences in LOS are not adjusted for differences in baseline characteristics. Services for home discharges include a home IV provider or being under the care of an organized home health service organization. Post-acute care facilities include skilled nursing facilities, intermediate care facilities, inpatient rehabilitation facilities, hospice facilities, long-term care hospitals, and psychiatric hospitals. LOS represents the number of midnights crossed during a hospitalization. Patient-directed discharge is coded as “against medical advice.” p-Values were calculated using the Student’s t test.
LOS, length of stay; SE, standard error.
