Clinical trajectories of critically ill patients discharged directly from a critical unit to a postacute care facility: retrospective cohort.

ABSTRACT

OBJECTIVE: To describe the clinical trajectories of patients discharged directly from a critical unit to a postacute care facility. METHODS: This was a retrospective cohort study of patients who were transferred from an intensive care unit or intermediate care unit to a postacute care facility between July 2017 and April 2023. Functional status was measured by the Functional Independence Measure score. RESULTS: A total of 847 patients were included in the study, and the mean age was 71 years. A total of 692 (82%) patients were admitted for rehabilitation, while 155 (18%) were admitted for palliative care. The mean length of stay in the postacute care facility was 36 days; 389 (45.9%) patients were discharged home, 173 (20.4%) were transferred to an acute hospital, and 285 (33.6%) died during hospitalization, of whom 263 (92%) had a do-not-resuscitate order. Of the patients admitted for rehabilitation purposes, 61 (9.4%) had a worsened functional status, 179 (27.6%) had no change in functional status, and 469 (63%) had an improved functional status during hospitalization. Moreover, 234 (33.8%) patients modified their care goals to palliative care, most of whom were in the group that did not improve functional status. Patients whose functional status improved during hospitalization were younger, had fewer comorbidities, had fewer previous hospitalizations, had lower rates of enteral feeding and tracheostomy, had higher Functional Independence Measure scores at admission to the postacute care facility and were more likely to be discharged home with less complex health care assistance. CONCLUSION: Postacute care facilities may play a role in the care of patients after discharge from intensive care units, both for those receiving rehabilitation and palliative care, especially for those with more severe illnesses who may not be discharged directly home.
