Association of diagnosed dementia with post-discharge mortality and readmission among hospitalized Medicare beneficiaries.
The purpose of this retrospective cohort study was to examine whether patients with dementia have a higher risk of adverse outcomes post-discharge. The researchers included Medicare beneficiaries hospitalized in 2016 and evaluated the co-primary outcomes of mortality and readmission within 30 days of hospital discharge. The final cohort included 1,089,109 hospitalizations of which 19.3% were of patients with diagnosed dementia and 886,411 were of patients without dementia. The study found that at 30 days following discharge, 5.7% of patients with dementia had died compared to 3.1% of patients without dementia. At 30 days following discharge, 17.7% of patients with dementia had been readmitted compared to 13.1% of patients without dementia. Patients with dementia who were discharged to the community had an increased likelihood of being readmitted than those who were discharged to nursing facilities, and, when readmitted, had an increased likelihood of dying during the readmission. The study concluded that diagnosed dementia was related with a substantially increased risk of mortality and a modestly increased risk of readmission within 30 days of discharge.

Continuity of nursing care in home health: impact on rehospitalization among older adults with dementia.
The objective of this retrospective cohort study was to examine the association between continuity of nursing care in home health care (HHC) and rehospitalization among persons with dementia (PWD). Multiple years of HHC assessment, administrative, and human resources data from a large urban not-for-profit home health agency was used. Findings showed that wide variations exist in continuity of nursing care to PWD. Consistency in nurse staff when providing HHC visits to PWD is critical for preventing rehospitalizations.
