## Abstract

Increasing numbers of patients with Alzheimer’s disease and related dementias (ADRD) are receiving post-
hospitalization care in skilled nursing facilities (SNFs). Most will transition from the SNF to home. Although
there has been a great deal of attention paid to patients’ transition from the hospital to home, there has been
little research on transitions from the SNF to home. Experiencing multiple transitions from home to the hospital
to a SNF and back to home is difficult for patients with ADRD and their caregivers. After discharge from SNF to
home, patients may re-enter the cycle of transitions, suffering adverse outcomes such as hospital
readmissions, medication errors, functional decline, and loss of independence.
This project will identify factors associated with 30-day hospital readmission and other adverse outcomes for
patients with ADRD who transition from the SNF to home. We will use the Health and Retirement Study (HRS),
a large, national dataset that includes rich social and economic information that is pertinent to the risk of
adverse health outcomes. Our study takes advantage of the link between the HRS and Centers for Medicare
and Medicaid Services billing data, and especially the link to extensive data collected during SNF stay as part
of the Minimum Data Set and home health event data from the Outcome and Assessment Information Set.
For Aim 1, we will describe the relationship of ADRD diagnosis or severity of cognitive impairment in the SNF
with hospital readmission for patients who transition from SNF to home. We hypothesize that individuals with
ADRD are at greater risk of hospital readmission when controlling for Andersen model factors. We also
propose that worse levels of cognitive impairment, as measured during a patient’s stay in the SNF, will be
associated with greater risk readmission risk. For Aim 2, we will identify the effect of early outpatient care,
either in clinic visit or via home health visit, on reducing readmissions. We hypothesize that early outpatient
care is protective against readmission. This represents a first step in identifying interventions to reduce
readmissions for people with ADRD who undergo this complex healthcare trajectory.
Dr. Carnahan’s career development plan will provide thorough training in research methods and health policy
related to transitions for older adults with ADRD. As an emerging aging researcher with expertise in the SNF to
home care transition, Dr. Carnahan will use the results of this study to design an intervention that improves the
health outcomes of cognitively impaired patients who experience this complex healthcare trajectory. Her long
term goal is to improve the quality of care and health outcomes for older adults with ADRD.
