Measurement of Physical Activity Among Hospitalized Older Adults Living With Dementia.

ABSTRACT: The purpose of this secondary data analysis was to describe physical activity and the factors associated with physical activity among older adults living with dementia on medical units in acute care settings. Measures included accelerometry data from the MotionWatch 8, behavioral and psychological symptoms associated with dementia, use of psychotropic medications, subjective reports of activities of daily living and other types of physical activity (e.g., walking to the bathroom, participating in therapy), delirium severity, and medications. The majority of the 204 participants were White (70%) and female (62%), with a mean age of 83 years. Over 24 hours of assessment, participants engaged in 15 (SD = 46) minutes of vigorous activity, 43 (SD = 54) minutes of moderate activity, 2 hours 50 (SD = 2) minutes of low-level activity, and 20 (SD = 3) hours of sedentary activity. Subjective walking activities, toileting, evidence of disinhibition, delirium severity, agitation, and use of psychotropic medications were associated with increased physical activity based on the MotionWatch 8. The findings provide information for rehabilitation nurses regarding factors associated with physical activity among patients with dementia admitted to acute care settings as well as some of the challenges associated with measurement of physical activity. Future research needs to continue to explore the impact of behavioral symptoms associated with dementia on physical activity and increase participation in activities that are functionally relevant.

Mediating role of care partner burden among dementia care partners during post-hospital transition.

OBJECTIVES: This study examined the mediating role of care partner burden on the relationship between patient clinical factors (i.e. cognition, physical function, and behavioral and psychological symptoms of dementia [BPSD]) and care partner mental health (i.e. anxiety and depression) among dementia care partners at hospital discharge. METHOD: The sample consisted of 431 patient and care partner dyads enrolled in the Family centered Function-focused Care (Fam-FFC) study; ClinicalTrials.gov identifier NCT03046121. Mediation analyses were conducted to test the role of care partner burden on the associations between patient clinical factors, and care partner anxiety and depression. RESULTS: Mediation models demonstrated that care partner burden partially mediated the relationship between patient physical function and care partner anxiety and depression, as well as patient BPSD and care partner anxiety and depression. CONCLUSION: Findings highlight the need for clinicians and service providers to implement comprehensive strategies that address both patient clinical factors (i.e. physical function and BPSD) and care partner burden, to optimize care partner mental health outcomes during post-hospital transition.

Pilot Process Evaluation of the Supporting Older Adults at Risk Model: A RE-AIM Approach.

ABSTRACT: Despite evidence supporting transitional care models, hospitals report challenges implementing and sustaining them. The Discharge to Assess (D2A) Model is an innovative solution to this problem but required translation from a national health system context to an U.S.-based context. We translated the central tenets of the D2A model to establish the Supporting Older Adults at Risk (SOAR) Model, which unfolds in three phases: Prepare, Transition, and Support. The purpose of this project was to conduct a process evaluation of the SOAR Model in practice using the RE-AIM Framework (Reach, Effectiveness, Adoption, Implementation, and Maintenance). Forty patients completed all SOAR Model components for a Reach of 21%. Patients averaged 80 years of age, 53% were female, and 64% Black/AA. SOAR significantly improved discharge before noon, time to first home visit, and use of the in-house pharmacy. SOAR also improved length of hospital stay, emergency department visits, and readmissions. Twenty-one of the 26 Implementation measures unfolded with 75% or greater fidelity. Sixteen of the 24 Adoption measures unfolded with 75% or greater fidelity. COVID-19 limited Maintenance. Given the model unfolds across settings over time, requiring adoption from interprofessional team members, patients, and families, future work should focus on improving reach and adoption.

" I'm not a risk taker " : Risk Perceptions of Nursing Home Residents With Dementia.

BACKGROUND: Persons living with Alzheimer disease and related dementia (ADRD) in nursing homes (NH) are often excluded from conversations about their health/safety. These omissions impinge on personhood and the rights to have care preferences heard and honored. While persons with ADRD maintain the ability to communicate their preferences long after their decision-making abilities are affected, little is known about how persons with ADRD understand the risks associated with their preferences. METHODS: As part of a larger focused ethnography, in-depth interviews and an adapted risk propensity questionnaire explored the risk perceptions of NH residents with ADRD (N=7) associated with their preferences for care and activities of daily living. RESULTS: Residents generally self-identified as risk avoiders ( M =3.2±1.84) on the risk propensity scale and were able to rate risk associated with preferences described within 5 thematic categories: 1) participation in decision-making, 2) risk awareness, 3) paying attention to safety, 4) reliance on nursing home staff and family, and 5) impacts on quality of life and quality of care. DISCUSSION: Results suggest NH residents with ADRD can express risk surrounding their preferences and should be encouraged to participate in discussions about their health and safety.

The association between patient engagement and quality of care interactions among acute care patients with dementia.

Effective staff-patient communication is critical in acute care settings, particularly for patients with dementia. Limited work has examined the impact of quality of staff-patient care interactions on patient engagement. The purpose of this study was to determine whether the quality of staff-patient care interactions were associated with active patient engagement during the interaction after controlling for relevant covariates. The study was a secondary data analysis using baseline data from the Function Focused Care for Acute Care intervention study, with a total sample of 286 patients. Descriptive statistics and a generalized linear mixed model were used. The findings indicated that there was a significant relationship between the quality of care interactions and patient engagement such that receiving positive care interactions resulted in higher odds of active patient engagement. These findings can inform future interventions and training for acute care staff to improve quality of care interactions and patient engagement.

Ready or Not: A Conceptual Model of Organizational Readiness for Embedded Pragmatic Dementia Research.

The National Institute on Aging Alzheimer's Disease/Alzheimer's Disease and Related Dementias Research Implementation Milestones emphasize the need for implementation research that maximizes up-take and scale-up of evidence-based dementia care practices across settings, diverse populations, and disease trajectories. Organizational readiness for implementation is a salient consideration when planning and conducting embedded pragmatic trials, in which interventions are implemented by provider staff. The current article examines the conceptual and theoretical underpinnings of organizational readiness for implementation and the operationalization of this construct. We offer a preliminary conceptual model for explicating and measuring organizational readiness and describe the unique characteristics and demands of implementing evidence-based interventions targeting persons with dementia and/or their care partners.

Trends in observation stays for Medicare beneficiaries with and without Alzheimer's disease and related dementias.

BACKGROUND: There has been a marked rise in the use of observation care for Medicare beneficiaries visiting the emergency department (ED) in recent years. Whether trends in observation use differ for people with Alzheimer's disease and Alzheimer's disease-related dementias (AD/ADRD) is unknown. METHODS: Using a national 20% sample of Medicare beneficiaries ages 68+ from 2012 to 2018, we compared trends in ED visits and observation stays by AD/ADRD status for beneficiaries visiting the ED. We then examined the degree to which trends differed by nursing home (NH) residency status, assigning beneficiaries to four groups: AD/ADRD residing in NH (AD/ADRD+ NH+), AD/ADRD not residing in NH (AD/ADRD+ NH-), no AD/ADRD residing in NH (AD/ADRD- NH+), and no AD/ADRD not residing in NH (AD/ADRD- NH-). RESULTS: Of 7,489,780 unique beneficiaries, 18.6% had an AD/ADRD diagnosis. Beneficiaries with AD/ADRD had more than double the number of ED visits per 1000 in all years compared to those without AD/ADRD and saw a faster adjusted increase over time (+26.7 vs. +8.2 visits/year; p < 0.001 for interaction). The annual increase in the adjusted proportion of ED visits ending in observation was also greater among people with AD/ADRD (+0.78%/year, 95% CI 0.77-0.80%) compared to those without AD/ADRD (+0.63%/year, 95% CI 0.59-0.66%; p < 0.001 for interaction). Observation utilization was greatest for the AD/ADRD+ NH+ population and lowest for the AD/ADRD- NH- population, but the AD/ADRD+ NH- group saw the greatest increase in observation stays over time (+15.4 stays per 1000 people per year, 95% CI 15.0-15.7). CONCLUSIONS: Medicare beneficiaries with AD/ADRD have seen a disproportionate increase in observation utilization in recent years, driven by both an increase in ED visits and an increase in the proportion of ED visits ending in observation.

Delirium Severity and Physical Function in Hospitalized Persons Living With Dementia: Moderation by Age, Sex, and Race.

OBJECTIVE: This study investigated whether demographic characteristics (age, sex, and race) moderated delirium severity as a predictor of physical function in hospitalized persons living with dementia. METHODS: The sample consisted of 351 patients enrolled in a randomized controlled trial (Function Focused Care for Acute Care Using the Evidence Integration Triangle). Preliminary analysis was conducted to assess the main effect, and multiple linear regression was used to examine the moderating effect of demographic characteristics between delirium severity and physical function. RESULTS: Both age and sex were found to have significant moderating effects on the relationship between delirium severity and physical function (ß = 2.22; P = 0.02 and ß = 1.34; P = 0.04, respectively). Older adults aged 85 years or older with higher levels of delirium severity reported lower levels of physical function compared with older adults aged 65 to 84 years. Males with higher levels of delirium severity reported lower levels of physical function compared with females. Race did not significantly moderate the association between delirium severity and physical function (ß = 0.22; P = 0.90). CONCLUSIONS: Our findings suggest that age and sex may have differential effects on physical function across different levels of delirium severity in hospitalized persons living with dementia.

Behavioral and psychological symptoms of dementia and adverse patient outcomes post-hospitalization.

OBJECTIVES: The occurrence of behavioral and psychological symptoms of dementia (BPSD) are associated with adverse outcomes but have largely been studied in populations outside of acute care. The current study examines (1) the prevalence of BPSD during acute hospitalization and (2) if BPSD are predictive of adverse patient outcomes. METHODS: A secondary analysis of Family-centered Function-focused Care (Fam-FFC) data including 461 patients with dementia/care partner dyads assessed at hospital admission, discharge, 2 months, and 6 months post-discharge, was conducted. Prevalence of BPSD (Neuropsychiatric Inventory-Questionnaire total and Frontal, Hyperactivity, Mood, and Psychosis sub-categories), associations with patient and care partner characteristics, and prediction of adverse events (falls, emergency room [ER] visits, hospitalizations, injury) were examined. RESULTS: BPSD were highly prevalent (93.9% admission, 86.7% discharge). The most common symptom cluster at admission was Hyperactivity (76.7%) followed by Mood (72.3%) and Psychosis (71.9%), and Frontal (25.9%). Higher admission Hyperactivity was associated with ER admissions at 2 months, higher discharge Hyperactivity was associated with ER admissions and hospitalizations at 2 months, and change in Psychosis was associated with ER admissions at 2 months. CONCLUSIONS: These findings highlight BPSD during hospitalization as potentially modifiable risk factors of adverse outcomes.

Using Hybrid Effectiveness Studies to Facilitate Implementation in Community-Based Settings: Three Case Studies in Dementia Care Research.

The pipeline from discovery to testing and then implementing evidence-based innovations in real-world contexts may take 2 decades or more to achieve. Implementation science innovations, such as hybrid studies that combine effectiveness and implementation research questions, may help to bridge the chasm between intervention testing and implementation in dementia care. This paper describes hybrid effectiveness studies and presents 3 examples of dementia care interventions conducted in various community-based settings. Studies that focus on outcomes and implementation processes simultaneously may result in a truncated and more efficient implementation pipeline, thereby providing older persons, their families, health care providers, and communities with the best evidence to improve quality of life and care more rapidly. We offer post-acute and long-term care researchers considerations related to study design, sampling, data collection, and analysis that they can apply to their own dementia and other chronic disease care investigations.

A Descriptive Study Using Rasch Analysis and Hypothesis Testing to Evaluate the Psychometric Properties of the UMOVE Mobility Screen Tested With Hospitalized Older Adults.

The purpose of this study was to test the reliability and validity of the UMOVE Mobility Screen in older adults living with dementia using a Rasch analysis and hypothesis testing. The UMOVE Mobility Screen (UMOVE) focuses on nine activities: following commands, muscle strength, and basic functional mobility tasks. Trained evaluators completed assessments on 244 patients, the majority of whom were female (62%), and White (71%). Based on Rasch Analysis, there was evidence of good item and person reliability (indexes > 0.80), good INFIT statistics, and only one item fitting the model based on OUTFIT statistics. Validity was supported based on hypothesis testing. There was no evidence of Differential Item Functioning between races and genders. Item mapping raised concerns about the spread of the items across the full spectrum of mobility assessed in the UMOVE Mobility Screen. Future testing should consider adding some easier and some more difficult items.

An exploration of the cultural appropriateness of the family-centered function-focused care intervention.

The Family-centered Function Focused Care (Fam-FFC) intervention, is a nurse-family care partnership model aimed to improve the physical and cognitive recovery in hospitalized persons living with Alzheimer's Disease Related Dementias (ADRD) while improving the care partner's experiences. Discussions of patients' needs and preferences between nurses and the patient's close family members have been found to be useful in preventing excessive stress in persons with dementia, while lessening the anxiety of care partners. However, the efficacy of dementia-specific interventions is influenced in part by the degree to which the interventions are flexible and sensitive to the patient's and care-partner's condition, needs, and preferences, including cultural preferences. Therefore, the purpose of this study is to assess the cultural appropriateness of Fam-FFC using the Ecological Validity Model (EVM). This qualitative, descriptive study included 28 consented care partners drawn from a sample of 455 dyads enrolled in the Fam-FFC intervention. An interview guide was created based on the EVM. Participants provided demographic data. Thematic analysis was conducted to analyze transcribed interviews. The majority of the sample was female (79%), Non-Hispanic (96%) and half were married. One-half of the sample represented Black care partners and one-half were White. Seventy-nine percent lived with their family member with ADRD. Three major themes were identified from the thematic analysis including Care Partner Identity, Care Partner Preferences, and Goals of Care for functional recovery of their family member living with dementia. In this study care partners wanted more social services as well as home care that supported not just physical needs but also social and recreational needs. Findings from the study offer guidance on improving the Fam-FFC intervention including strengthening education and resources on partner self-care.

Factors associated with disagreement between clinician app-based ultra-brief Confusion Assessment Method and reference standard delirium assessments.

BACKGROUND: Recently, the Ultra-Brief Confusion Assessment Method (UB-CAM), designed to help physicians and nurses to recognize delirium, showed high, but imperfect, accuracy compared with Research Reference Standard Delirium Assessments (RRSDAs). The aim of this study is to identify factors associated with disagreement between clinicians' app-based UB-CAM assessments and RRSDAs. METHODS: This is a secondary analysis of a prospective diagnostic test study. The study was conducted at two hospitals and included 527 inpatients (≥70 years old) and 289 clinicians (53 physicians, 236 nurses). Trained research associates performed RRSDAs and determined delirium presence using the CAM. Clinicians administered the UB-CAM using an iPad app. Disagreement factors considered were clinician, patient, and delirium characteristics. We report odds ratios and 95% confidence intervals. RESULTS: One thousand seven hundred and ninety-five clinician UB-CAM assessments paired with RRSDAs were administered. The prevalence of delirium was 17%. The rate of disagreement between clinician UB-CAM assessments and RRSDAs was 12%. Significant factors associated with disagreement between clinician UB-CAM assessments and RRSDAs (OR [95% CI]) included: presence of dementia (2.7 [1.8-4.1]), patient education high school or less (1.9 [1.3-2.9]), psychomotor retardation (2.5 [1.4-4.2]), and the presence of mild delirium or subsyndromal delirium (5.5 [3.5-8.7]). Significant risk factors for false negatives were patient age less than 80 (2.2 [1.1-4.3]) and mild delirium (3.5 [1.6-7.4]). Significant risk factors for false positives were presence of dementia (4.0 [2.3-7.0]), subsyndromal delirium (5.1 [2.9-9.1]), and patient education high school or less (2.0 [1.2-3.6]). Clinician characteristics were not significantly associated with disagreement. CONCLUSIONS: The strongest factors associated with disagreement between clinician UB-CAM screens and RRSDAs were the presence of dementia and subsyndromal delirium as risk factors for false positives, and mild delirium and younger age as a risk factor for false negatives. These disagreement factors contrast with previous studies of risk factors for incorrect clinician delirium screening, and better align screening results with patient outcomes.

Testing an Intervention to Improve Posthospital Outcomes in Persons Living With Dementia and Their Family Care Partners.

Background and Objectives: Hospitalized persons living with dementia are at risk for functional decline, behavioral symptoms of distress, and delirium, all persisting in the postacute period. In turn, family care partners (FCPs) experience increased anxiety and lack of preparedness for caregiving, compounding existing strain and burden. Family-centered Function-focused Care (Fam-FFC) purposefully engages FCPs in assessment, decision-making, care delivery, and evaluation of function-focused care during and after hospitalization (within 48 hours of discharge, weekly telephone calls for a total of 7 additional weeks, then monthly for 4 months). The objective of this study was to test the efficacy of Fam-FFC. Research Design and Methods: A cluster randomized controlled trial included 455 dyads of persons living with dementia and FCPs in 6 medical units in 3 hospitals. Patient outcomes included return to baseline physical function, behavioral symptoms of distress, depressive symptoms, and delirium severity. Family care partner measures included preparedness for caregiving, anxiety, strain, and burden. Results: Multilevel level modeling demonstrated that the likelihood of returning to baseline function across time for Fam-FFC participants was twice that of the control group by the end of 6 months (OR = 2.4, p = .01, 95% CI 1.2-4.7). Family-centered Function-focused Care was also associated with fewer symptoms of distress (b = -1.1, SE = 0.56, p = .05) but no differences in the amount of moderate physical activity, depressive symptoms, and delirium severity. Preparedness for caregiving increased significantly only from 2 to 6 months (b = 0.89, SE = 0.45, d = 0.21, overall p = .02) in the intervention group, with no group differences in anxiety, strain, and burden. Discussion and Implications: Family-centered Function-focused Care may help prevent some of the postacute functional decline and behavioral symptoms in hospitalized persons living with dementia. Further research is needed to promote sustained improvements in these symptoms with more attention to the postacute needs of the care partner.

Gender, Pain, and Function Associated With Physical Activity After Hospitalization in Persons Living With Dementia.

BACKGROUND: The purpose of this study was to identify factors that are associated with physical activity after hospitalization in persons living with dementia. METHODS: Multiple linear regressions were conducted to test factors associated with objective activity levels (sedentary, low, moderate, and vigorous) among 244 patients living with dementia from a randomized controlled trial. RESULTS: Within 48 hours of hospital discharge, time in sedentary behavior was associated with increased pain (ß=0.164, P =0.015). Time in low activity was associated with less pain (ß=-0.130, P =0.049) and higher physical function (ß=0.300, P =<0.001). Time in moderate activity was associated with increased physical function (ß=0.190, P =0.008) and male gender (ß=0.155, P =0.016). No significant associations of potential factors were found with time in vigorous activity. CONCLUSIONS: Our findings suggest that managing or reducing pain, encouraging individual functional level, and gender could influence time spent in physical activity after acute hospitalization in persons living with dementia.

Caregiver preparedness is associated with desire to seek long-term care admission of hospitalized persons with dementia.

INTRODUCTION: Hospitalized patients with dementia are more likely to be discharged to long-term care compared to persons without dementia. Little research has been conducted to examine the associations of caregiver preparedness and strain with desire to seek long-term care in hospitalized persons with dementia at discharge. The purpose of this study was to examine caregiver preparedness and strain as factors associated with desire to seek long-term care admission in caregivers of persons with dementia at hospital discharge. METHODS: Patient baseline and discharge data, and caregiver discharge data of 424 patient and caregiver dyads from a cluster randomized trial was used. Stepwise multiple linear regression was conducted to examine factors associated with caregiver desire to seek long-term care. RESULTS: After controlling for caregiver and patient characteristics, lower caregiver preparedness (ß = -0.069; p < 0.016) was significantly associated with increased desire to seek long-term care. DISCUSSION: Findings underscore the need for clinicians and service providers to provide further attention to caregiver preparedness throughout the course of hospitalization.

Clinical factors associated with the quality of interactions between staff and hospitalized older patients with dementia.

This study examines the clinical factors associated with the quality of interactions between staff and hospitalized older patients with dementia. Following examination of bivariate associations, we conducted multiple linear regression in a sample of 140 hospitalized older patients with dementia who participated in the final cohort of an intervention study implementing Family-centered Function-focused Care (Fam-FFC). On average, the participants (male = 46.1%, female = 52.9%) were 81.43 years old (SD = 8.29) and had positive interactions with staff (mean QUIS score = 5.84, SD = 1.36). Accounting for 17.8% of variance in the model, non-pharmacological intervention use (b= 0.170; p<.001) and pain (b= -0.198; p<.01) were significantly associated with the quality of staff-patient interactions. To optimize care of hospitalized patients with dementia, staff should be encouraged to use non-pharmacological interventions. It is also important for staff to assess pain among the patients with dementia and prioritize pain management.

Reducing Behavioral and Psychological Symptoms of Dementia in Acutely Ill Patients via Patient Engagement Specialists: A Pilot Feasibility Study.

Behavioral and psychological symptoms of dementia (BPSD) are common in hospitalized persons living with dementia (PLWD). This pilot aimed to test the feasibility of an innovative model of care, PES-4-BPSD (a dementia unit staffed with Patient Engagement Specialists, PES). Non-randomized pilot feasibility trial was conducted, enrolling N = 158 patients to the intervention unit (n = 79, a 10-bed dementia unit, staffed with nursing assistants, NAs, with mental health backgrounds, PES) and an enhanced control unit (n = 79, 40-bed medicine unit, staffed with NAs). All NAs/PES (N = 63) received dementia training, with completion rate of 82.5%. Overall, patients had ~1 NPI-Q (Neuropsychiatric Inventory Questionnaire) assessment/48 hr. 97% (n = 153) of PLWD exhibited at least one behavior. Average NPI-Q scores did not differ across intervention (5.36) and control (3.87) units (p = .23). Patients on the intervention unit had 88% (p = .002) shorter duration of constant observation. A dementia care unit staffed by PES is an innovative model requiring further research.

Differences in Medication Use by Gender and Race in Hospitalized Persons Living with Dementia.

The purpose of this study was to describe differences in treatment of White versus Black older adults, males versus females, and those living at home, assisted living, or nursing home communities with regard to the use of psychotropic, pain, and cardiovascular medications. Baseline data from the first 352 participants in the study, implementation of Function-Focused Care for Acute Care Using the Evidence Integration Triangle, were used. Data included age, gender, race, comorbidities, admission diagnosis, and living location prior to hospitalization, the Saint Louis University Mental Status exam, the modified Charlson Comorbidity Index, the Pain Assessment in Advanced Dementia scale, the Confusion Assessment Method, and medications prescribed. Generalized linear mixed model analyses were done, controlling for race or gender (depending on which comparison analysis was being done), age, cognitive status, hospital, delirium, and comorbidities. Medication use was significantly higher for White older adults, compared to Black older adults, for antidepressants, anxiolytics, non-opioid pain medications, and opioids and lower for antihypertensives. Females received more anxiolytics than their male counterparts. There were differences in medication use by living location with regard to non-opioid pain medication, antipsychotics, statins, and anticoagulants. The findings provide some current information about differences in medication use across groups of individuals and can help guide future research and hypothesis testing for approaches to minimizing these differences in treatment.
