Persons with Alzheimer's Disease and Related Dementias (ADRD) account for 3.2 million hospital admissions per year and have over three times more hospitalizations than those without cognitive impairment, yet hospital caregivers (HCGs) are ill-prepared to manage patients with ADRD with less than 5% reporting mandatory dementia care training. Three-quarters of hospitalized persons with ADRD display Behavioral and Psychological Symptoms of Dementia (BPSD) associated with functional and cognitive decline, increased resource consumption, institutionalization, premature death, and caregiver burden. The overall objective is to test the preliminary efficacy of an innovative model of care, PES-4-BPSD, for reducing BPSD by empowering Patient Engagement Specialists (PES) to deliver dementia care for acutely-ill patients with ADRD. Traditionally, mental health assistants with training in crisis-prevention techniques provide care to psychiatric patients. On the intervention unit, these mental health assistants, as PES, purposefully engage patients with BPSD. In the pilot study, investigators found patients with cognitive impairment admitted to the PES unit were significantly less likely to require constant observation, chemical and physical restraints, suggesting improved management of BPSD. The central hypothesis is that PES-4-BPSD will improve the ability of PES to create an "enabling" milieu that addresses factors leading to BPSD and improves the experience of hospital caregivers. Guided by a social-ecological framework, PES-4-BPSD incorporates dementia education and training, environmental modifications-cohorting, increased staffing-PES, and staff support. The investigators' multidisciplinary research team is well-positioned to accomplish the following: Aim 1) Determine the preliminary efficacy of PES-4-BPSD for reducing BPSD during hospitalization, and Aim 2) Evaluate whether dementia care training improves the perceived ability of PES staff (intervention) and nurse assistant staff (control) to care for hospitalized persons with ADRD. For Aim 1, investigators will conduct a non-randomized preliminary efficacy trial of the PES-4-BPSD intervention enrolling N=158 patients (79 control, 79 intervention). The primary outcome will be presence of BPSD during hospitalization using the Neuropsychiatric Inventory-Questionnaire (NPI-Q). In Aim 2, investigators will use survey methodology in a repeated measures design to evaluate within and between-group differences in attitudes, experience, and satisfaction toward managing patients with ADRD. Measures will be completed at baseline (T1), immediately following training (T2), and at the end of the intervention period (T3). This proposal will be the first to study an innovative model of care utilizing PES as specialized hospital caregivers for reducing BPSD in the hospital setting. The investigators' findings will lay the essential groundwork for a multi-site trial of PES-4-BPSD and inform the development of a program that can be easily implemented in other hospitals.

Prior to patient recruitment, a 3 month dementia training program will be implemented on both the intervention and control units. On the intervention unit, training will target the Patient Engagement Specialists (PES) and on the control to the nurse assistants (please refer to NCT# 04179721 for more details on this aim). Following the implementation of the dementia care training, eligible patients will be offered the opportunity to participate in the study. A research coordinator will offer the information and opportunity to participate to the patient's lawful caregiver. The signed consent forms will be stored in secured file cabinets. Once a participant has been enrolled in the study, demographic information will be obtained from the electronic medical records (EMR) and verified by Family Caregiver (FCG), including: age, gender, race/ethnicity, marital status, education, work status, current living situation, medical comorbidities, and reason for admission. A member of the research team will conduct a short interview with the FCG to verify patient background information and obtain baseline (1 month prior to admission) functional status (Barthel Index), dementia severity cognitive (Clinical Dementia Rating Scale)(5 stages of severity: no 0, questionable 0.5, mild 1, moderate 2, and severe 3), and behavioral symptoms using the Neuropsychiatric Inventory-Clinical version NPI-C.

A member of the research team will then complete daily NPI-Qs to determine the number of behaviors and symptoms for each patient on a daily basis. The data collector will use a multimodal approach drawing from electronic medical record (EMR) notes and interviews with nursing staff regarding the patient's behavior and treatment over the past 24 hours. Delirium will be assessed daily by the research coordinator using same multimodal approach and during the time of NPI observation. A final EMR chart review will be conducted collecting information such as length of stay, discharge disposition, in-hospital mortality as well as total usage practices for management of BPSD: use of special observation (1:1 or enhanced), restraints, psychoactive medications, psychiatric evaluation. Within 48 hours of discharge, family caregivers will be interviewed regarding satisfaction with care using the Carer Questionnaire Data from the National Audit of Dementia Round 3.
