This is a Mentored Physician-Scientist Award in Alzheimer’s Disease and Related Dementias (ADRD) application for Dr. Molly Horstman, a hospitalist and health services researcher at the Michael E. DeBakey VA Medical Center, who is establishing herself as a young investigator at the intersection of hospital medicine, dementia, and caregiving. This award will provide Dr. Horstman with the necessary support (1) to develop expertise in ADRD and dementia caregiving, (2) to receive formal training in implementation science research methods, and (3) to gain the experience needed to establish herself as an independent physician-scientist. To achieve these goals, Dr. Horstman has assembled a multidisciplinary mentoring team of nationally recognized investigators in ADRD, Dementia Caregiving, Geriatrics, and Implementation Science research methods. Hospital admissions are sentinel events for Veterans with ADRD and their family caregivers. Adults with ADRD are often discharged from the hospital with new functional and cognitive limitations, which increases demands on family caregivers following discharge. These changing caregiver demands increase caregiver stress, which can lead to worse outcomes for caregivers and care recipients. Over 20 years of research has demonstrated that care transitions interventions started in the hospital can improve outcomes for patients. Furthermore, care transitions interventions started in the hospital and designed specifically to meet the needs of stroke caregivers have been shown to reduce caregiver burden and anxiety and reduce acute care resource use following discharge. To date, this evidence base supporting tailored interventions to meet specific caregiver needs has not been translated to the support for dementia caregivers during care transitions. Resources for Enhancing Alzheimer’s Caregiver Health (REACH II) is a multicomponent, evidence-based ADRD caregiver support program that has been adapted and implemented in the Veterans Health Administration as REACH VA. When delivered in the community, REACH II and REACH VA were associated with improvements in caregiver depression, caregiver social support, and caregiver self-care and a decrease in caregiver burden and problem behaviors in the care recipient. Evidence-based interventions, like REACH II, are challenging to scale and spread due to the need for one-on-one interactions between caregivers and dementia care specialists for skills training. GamePlan4Care (GP4C) is a novel, web-based training platform designed to fully replicate the core components of REACH II in an acceptable and scalable online platform informed by user-centered testing. With adaptation to the hospital setting to include care transitions training, GP4C has great potential to transform the support of ADRD caregivers during care transitions. This proposal will combine evidence-informed care transitions training with an existing dementia caregiver support intervention to create a new and unique inte...
