Creating a Supportive Environment Using Cues for Wayfinding in Dementia

Background: Regional variation in the utilization of health services is a well-documented phenomenon in health care with numerous studies reporting substantial and unexplained variations in coronary revascularization. In the Canadian province of British Columbia (BC), five cardiac centers provide coronary revascularization services. In 2011 Cardiac Services BC (CSBC) undertook a study that identified substantial regional variation in coronary revascularization that could not be explained by patient characteristics or risk factors. Following this initial project, CSBC launched an initiative to help better understand the regional variations and possibly devise and implement strategies to reduce them. Methods: Using Lean methodology, we are mapping the key processes of care for ACS patients across BC (initially excluding emergent STEMI and cardiogenic shock) at each cardiac centre. The ACS patient journey will be mapped from admission to discharge through several key decision points that determine whether they will continue through to diagnostic catheterization and revascularization or to be medically managed alone. The key decision points are: 1. Decision to refer to diagnostic catheterization and subsequent transfer if necessary. 2. Decision to continue to a revascularization procedure (PCI or CABG) after diagnostic catheterization. The map will summarized these key decision points using multiple sources of data: 1. Flow and patient volumes into and out of each of these decision 2. Times between decision points and key care processes 3. Clinical influencers (ex: standard orders, best practice, established patterns of referral, and consultations) and non-clinical influencers (ex: resource capacity, transportation) that are considered at each decision point (process mapping and interview data). Discussion: BC is attempting to reduce unexplained variation in coronary revascularization using the Lean methodology to take a systematic approach to the analysis of the process of ACS care across the province. Involving physicians and point of care staff in the detailed mapping process has proven to be a significant step in engaging key stakeholders in the project by allowing input into the process of describing the factors affecting variation of practice at each site. The next step is to convene provincially to determine where to improve standardized practice in order to improve patient outcomes at key points along the value stream.

How to Prevent Antipsychotic Overuse in NHs

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. 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-). 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). 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.

Is donepezil therapy associated with reduced mortality in nursing home residents with dementia?

Both antidepressants and antipsychotics are used in older adults with behavioral symptoms of Alzheimer's disease and related dementias. Despite the prevalent use of these agents, little is known about their comparative risks for falls and fractures. Using 2007-2009 Medicare claims data linked to Minimum Data Set 2.0, we identified new users of antidepressants and antipsychotics among nursing home residents with Alzheimer's disease and related dementias who had moderate-to-severe behavioral symptoms. Separate discrete-time survival models were used to estimate risks of falls, fractures, and a composite of both among antidepressant group versus antipsychotic group. Compared to antipsychotic users, antidepressant users experienced significantly higher risk for fractures (adjusted hazard ratio = 1.35, 95% confidence interval = 1.10-1.66). The overall risk of falls or fractures remained significant in the antidepressant versus antipsychotic group (adjusted hazard ratio = 1.16, 95% confidence interval = 1.02-1.32). Antidepressants are associated with higher fall and fracture risk compared to antipsychotics in the management of older adults with Alzheimer's disease and related dementias who experience moderate-to-severe behavioral symptoms. Clinicians need to assess the ongoing risks/benefits of antidepressants for these symptoms especially in light of the increasingly prevalent use of these agents.

Background and ObjectivesPrevalence of nursing home residents with Alzheimer’s disease and related dementias (ADRD) has increased along with a growing consensus that person-centered ADRD care in nursing homes should maximize quality of life (QoL). However, concerns about whether residents with ADRD can make appropriate QoL judgments persist. This study assesses the stability and sensitivity of a self-reported, multidomain well-being QoL measure for nursing home residents with and without ADRD.Research Design and MethodsThis study linked the 2012–2015 Minnesota Nursing Home Resident QoL and Satisfaction with Care Survey, Minimum Data Set 3.0 (nursing home assessments), and Minnesota Department of Human Services Cost Reports. The QoL survey included cohort–resident pairs who participated for 2 consecutive years (N = 12 949; 8 803 unique residents from 2012–2013, 2013–2014, and 2014–2015 cohorts). Change in QoL between 2 years was conceptualized as stable when within 1.5 SD of the sample average. We used linear probability models to estimate associations of ADRD/Cognitive Function Scale status with the stability of QoL summary and domain scores (eg, social engagement) and the absolute change in QoL summary score, controlling for resident and facility characteristics.ResultsMost (86.82%) residents had stable QoL summary scores. Residents with moderate to severe cognitive impairment, irrespective of ADRD, were less likely to have stable summary scores than cognitively capable residents without ADRD (p < .001), but associations varied by QoL domains. Among those with stable summary QoL scores, changes in health/functional status were associated with absolute changes in summary QoL score (p < .001), suggesting sensitivity of the QoL measure.Discussion and ImplicationsQoL scores were similarly stable over time for most residents with and without ADRD diagnoses and were sensitive to changes in health/functional status. This self-reported QoL measure may be appropriate for nursing home residents, regardless of ADRD diagnosis, and can efficaciously be recommended to other states.

The purpose of this study was to compare the effects of 16 weeks of a comprehensive exercise routine to supervised walking and social conversation on depression in nursing home residents with Alzheimer's disease (AD). Method: This study was a three-group, repeated-measures design with random assignment to treatment group. Forty-five nursing home residents with moderate to severe AD were randomly assigned to a 16-week programme of comprehensive exercise, supervised walking or social conversation. Raters were blinded to treatment group assignment. Major outcome variables were depression measured by the Cornell Scale for Depression in Dementia, mood measured by the Dementia Mood Assessment Scale and the Alzheimer's Mood Scale, and affect measured by the Observed Affect Scale. Depression was reduced in all three groups with some evidence of superior benefit from exercise. Depression is a common problem with serious and costly consequences for nursing home residents with AD. Exercise as a behavioural approach to treatment of depression in nursing home residents with severe AD evidenced a clear benefit to participants in this study. More research is needed to clarify the relative benefits of different types of exercise in conjunction with or without pharmacological intervention.

Pragmatic Trials and Improving Long-Term Care: Recommendations From a National Institutes of Health Conference.

The purpose of this quasi-experimental study was to examine the effect of an intervention for caregivers of individuals with Alzheimer's disease and related dementias (ADRD) on nursing home residents' functional and cognitive status. Fourteen special care units (SCUs) in 14 midwestern nursing homes were paired according to size, ownership, and staff turnover. The paired nursing homes were randomly assigned to either experimental or control groups. The intervention consisted of the Family Involvement in Care (FIC) protocol. The FIC intervention was designed to help family caregivers of nursing home residents with dementia negotiate and establish a partnership with the staff caregivers for the care of residents. One hundred sixty-four residents participated in the study, 71 in the control group and 93 in the experimental group. Sixty-three residents were lost to attrition (38%). The experimental group exhibited less global deterioration throughout the study. Inappropriate behavior, cognition, and functional status remained relatively unchanged over time within and between the groups. Increased family involvement did slow global deterioration in individuals with ADRD. The findings of the study show that more factors need to be examined to discover those interventions that preserve functional and cognitive abilities.

Antipsychotic Drug Use Among Nursing Home Residents Taking Rivastigmine

Progressive deterioration in cognitive function and the ability to perform activities of daily living are the hallmarks of Alzheimer's disease (AD). As the disease progresses and behavioural/neuropsychiatric symptoms become more predominant, carers of AD patients themselves encounter a raft of physical, emotional, social and financial problems. Appropriate therapeutic management of AD patients, particularly their behavioural symptoms, may reduce the burden placed on family and professional caregivers. Preservation of cholinergic neurotransmission by cholinesterase inhibitors is the mainstay of pharmacological therapy for AD. Rivastigmine, a dual inhibitor of acetylcholinesterase and butyrylcholinesterase, has pharmacological properties that appear particularly favourable regarding the behavioural symptoms of AD. In addition to its beneficial effects on cognitive and global function, rivastigmine treatment in mild-to-moderate AD is associated with improvements in behavioural symptoms, a decreased requirement for antipsychotic drugs and delays in nursing home placement; reductions in caregiver burden, caregiver time and costs have also been reported. Rivastigmine treatment has also demonstrated improvements in behavioural symptoms and reductions in psychotropic medication usage in nursing home residents with moderate-to-severe AD, and may be associated with a reduction in professional caregiver burden. In summary, the positive effects of rivastigmine on functional and behavioural symptoms of AD help to reduce the time, stress and overall burden associated with caregiving, both in the informal home care and nursing home environments.

Pearls for Hypotension Treatment, With a Grain of Salt

Influence of visual stimuli on spatial navigation and memory of MCI, Alzheimer's disease patients and healthy control subjects

Assisted walking and walking combined with conversation were compared to a conversation-only intervention in nursing home residents with Alzheimer disease. Sixty-five subjects randomly assigned to treatment group were tested at baseline and end of treatment. Subjects' mean Mini-Mental State Examination score was 10.83; mean age was 87. Treatment was given for 30 minutes three times a week for 16 weeks. Subjects in the assisted walking group declined 20.9% in functional mobility; the conversation group declined 18.8%. The combined walking and conversation treatment group declined only 2.5%. These differences in outcome were significant and appear to have been affected by differences in treatment fidelity. Subjects in the conversation treatment group completed 90% of intended treatment compared with 75% in the combined group and only 57% in the assisted walking group. Failure to treat was due to subject refusal and physical illness. The conversation component of the combined walking and conversation treatment intervention appears to have improved compliance with the intervention, thereby improving treatment outcome. Results indicate that assisted walking with conversation can contribute to maintenance of functional mobility in institutionalized populations with Alzheimer disease. Staff assigned to this task should be prepared to use effective communication strategies to gain acceptance of the intervention.
