Association of incident dementia with hospitalizations

Rural and urban differences in quality of dementia care of persons with dementia and caregivers across all domains: a systematic review

BACKGROUND

There are challenges in healthcare service delivery in rural areas, and this may be especially true for persons with dementia, who have higher needs to access to the healthcare system, and may have difficulties to commute easily and safely to these services. There is a growing body of literature regarding geographical disparities, but there is no comprehensive systematic review of geographical differences in persons with dementia across all domains of care quality. Therefore, the objective of this study is to conduct a systematic review of the literature on rural and urban differences in quality of dementia care outcomes of persons with dementia across all quality-of-care domains.

METHODS

We performed a digital search in Ovid MEDLINE on July 16, 2019, updated on May 3, 2021, for French or English records. We selected studies that reported outcome from at least one domain of quality of dementia care (Access, Integration, Effective Care, Efficient Care, Population Health, Safety, and Patient-Centered) in both rural and urban persons with dementia or caregivers. We used rigorous, systematic methods for screening, selection, data extraction and we analyzed outcomes reported by at least two studies using vote counting and appraised the certainty of evidence. Finally, we explored sources of heterogeneity.

RESULTS

From the 38 included studies, we found differences in many dementia care domains. Rural persons with dementia had higher mortality rates (Population Health), lower visits to any physicians (Access), more hospitalizations but shorter stays (Integration), higher antipsychotic medications (Safety), lower use of home care services and higher use of nursing home (Patient-Centered Care) compared to urban persons with dementia.

CONCLUSIONS

This comprehensive portrait of rural-urban differences in dementia care highlights possible geographically based inequities and can be used by researchers and decision makers to guide development of more equitable dementia care policies.

The neuroimmune axis of Alzheimer's disease

Alzheimer's disease (AD) is a genetically complex and heterogeneous disorder with multifaceted neuropathological features, including β-amyloid plaques, neurofibrillary tangles, and neuroinflammation. Over the past decade, emerging evidence has implicated both beneficial and pathological roles for innate immune genes and immune cells, including peripheral immune cells such as T cells, which can infiltrate the brain and either ameliorate or exacerbate AD neuropathogenesis. These findings support a neuroimmune axis of AD, in which the interplay of adaptive and innate immune systems inside and outside the brain critically impacts the etiology and pathogenesis of AD. In this review, we discuss the complexities of AD neuropathology at the levels of genetics and cellular physiology, highlighting immune signaling pathways and genes associated with AD risk and interactions among both innate and adaptive immune cells in the AD brain. We emphasize the role of peripheral immune cells in AD and the mechanisms by which immune cells, such as T cells and monocytes, influence AD neuropathology, including microglial clearance of amyloid-β peptide, the key component of β-amyloid plaque cores, pro-inflammatory and cytotoxic activity of microglia, astrogliosis, and their interactions with the brain vasculature. Finally, we review the challenges and outlook for establishing immune-based therapies for treating and preventing AD.

Incipient dementia and avoidable hospital admission in persons with osteoarthritis

Objective

To investigate the associations between incipient dementia (ID) and hospitalization for ambulatory care sensitive conditions (ACSCs) among people with osteoarthritis (OA) of the peripheral joints.

Methods

Among individuals aged 51-99 years residing in Skåne, Sweden, in 2009, we identified those with a doctor-diagnosed OA and no dementia during 1998-2009 (n ​= ​57,733). Treating ID as a time-varying exposure, we followed people from January 1, 2010 or their 60th birthday (whichever occurred last) until hospitalization for ACSCs, death, 100th birthday, relocation outside Skåne, or December 31, 2019 (whichever occurred first). Using age as time scale, we applied flexible parametric survival models, adjusted for confounders, to assess the associations between ID and hospitalization for ACSCs.

Results

There were 58 and 33 hospitalizations for ACSCs per 1000 person-years among OA people with and without ID, respectively. The association between ID and hospitalization for any ACSCs was age-dependent with higher risk in ages<86 years and lower risks in older ages. Between ages 60 and 100 years, persons with ID had, on average, 5.8 (95% CI 0.9, 10.7), 1.6 (-2.6, 5.9) and 3.1 (2.3, 4.0) fewer hospital-free years for any, chronic and acute ACSCs, respectively, compared with persons without ID.

Conclusions

Among persons with OA, while ID was associated with increased risks of hospitalization for ACSCs in younger ages, it was associated with decreased risk in oldest ages. These results suggest the need for improvement in quality of ambulatory care including the continuity of care for people with OA having dementia.

Association Between Neuroticism and Dementia on Healthcare Use: A Multi-Level Analysis Across 27 Countries from The Survey of Health, Ageing and Retirement in Europe (SHARE)

BACKGROUND

People with high levels of neuroticism are greater users of health services. Similarly, people with dementia have a higher risk of hospitalization and medical visits. As a result, dementia and a high level of neuroticism increase healthcare use (HCU). However, how these joint factors impact the HCU at the population level is unknown. Similarly, no previous study has assessed the degree of generalization of such impacts, considering relevant variables including age, gender, socioeconomic, and country-level variability.

OBJECTIVE

To examine how neuroticism and dementia interact in the HCU.

METHODS

A cross-sectional study was performed on a sample of 76,561 people (2.4% with dementia) from 27 European countries and Israel. Data were analyzed with six steps multilevel non-binomial regression modeling, a statistical method that accounts for correlation in the data taken within the same participant.

RESULTS

Both dementia (Incidence Rate Ratio (IRR): 1.537; α= 0.000) and neuroticism (IRR: 1.122; α= 0.000) increased the HCU. The effect of having dementia and the level of neuroticism increased the HCU: around 53.67% for the case of having dementia, and 12.05% for each increment in the level of neuroticism. Conversely, high levels of neuroticism in dementia decreased HCU (IRR: 0.962; α= 0.073). These results remained robust when controlling for age, gender, socioeconomic, and country-levels effects.

CONCLUSION

Contrary to previous findings, neuroticism trait in people with dementia decreases the HCU across sociodemographic, socioeconomic, and country heterogeneity. These results, which take into account this personality trait among people with dementia, are relevant for the planning of health and social services.

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.

Hospitalizations in older-adults newly diagnosed with dementia: A population-based longitudinal study in Israel

OBJECTIVES

To compare inpatient burden (i.e. likelihood of hospitalization, number of admissions and length of stay) in persons with newly diagnosed dementia to the general population without dementia. Additionally, to evaluate whether inpatient burden is increased during the years prior to and post dementia diagnosis, and to identify factors associated with increased inpatient burden.

METHOD

The Israeli National Dementia Dataset (2016) was cross-linked with the National Hospital Discharge Database of the Israeli Ministry of Health (2014-2018). Dementia definition was based on documented dementia diagnoses and/or the purchase of medications during 2016. Mixed-effects models were applied to identify demographic and health characteristics associated with inpatient burden in the one and 2 years prior to and after dementia diagnosis.

RESULTS

The dataset included 11,625 individuals aged ≥65 years, identified as incident dementia cases. Compared to the general population of older-adults without dementia, those with newly diagnosed dementia had a higher age-standardized proportion of hospitalizations (26.4% vs. 40%). The odds for hospitalization were highest during the year preceding dementia diagnosis (OR = 3.19, 95% CI 2.51-4.06) compared to 2 years prior to diagnosis, and remained high (although slightly decreased) after dementia diagnosis. Older age was associated with inpatient burden after, but not prior to dementia diagnosis.

CONCLUSIONS

Older persons with dementia are a vulnerable population group with increased utilization of inpatient burden compared to those without dementia, particularly in the years surrounding dementia diagnosis. Sociodemographic risk factors may differ with respect to the time surrounding dementia diagnosis.

Dementia Attributable Healthcare Utilizations in the Caribbean versus United States

BACKGROUND

Despite the high burden of Alzheimer's disease and other dementias among the Hispanic population worldwide, little is known about how dementia affects healthcare utilizations among this population outside of the US, in particular among those in the Caribbean region.

OBJECTIVE

This study examines healthcare utilization associated with Alzheimer's disease and other dementias among older adults in the Caribbean as compared to the US.

METHODS

We conducted harmonized analyses of two population-based surveys, the 10/66 Dementia Group Research data collected in Dominican Republic, Cuba, and Puerto Rico, and the US-based Health and Retirement Study. We examined changes in hospital nights and physician visits in response to incident and ongoing dementias.

RESULTS

Incident dementia significantly increased the risk of hospitalization and number of hospital nights in both populations. Ongoing dementia increased the risk of hospitalization and hospital nights in the US, with imprecise estimates for the Caribbean. The number of physician visits was elevated in the US but not in the Caribbean.

CONCLUSIONS

The concentration of increased healthcare utilization on hospital care and among patients with incident dementia suggests an opportunity for improved outpatient management of new and existing dementia patients in the Caribbean.

Public spending on acute and long-term care for Alzheimer's disease and related dementias

INTRODUCTION

We estimate the spending attributable to Alzheimer's disease and related dementias (ADRD) to the United States government for the first 5 years post-diagnosis.

METHODS

Using data from the Health and Retirement Study matched to Medicare and Medicaid claims, we identify a retrospective cohort of adults with a claims-based ADRD diagnosis along with matched controls.

RESULTS

The costs attributable to ADRD are $15,632 for traditional Medicare and $8833 for Medicaid per dementia case over the first 5 years after diagnosis. Seventy percent of Medicare costs occur in the first 2 years; Medicaid costs are concentrated among the longer-lived beneficiaries who are more likely to need long-term care and become Medicaid eligible.

DISCUSSION

Because the distribution of the incremental costs varies over time and between insurance programs, when interventions occur and the effect on the disease course will have implications for how much and which program reaps the benefits.

Association of Diagnosed Dementia with Post-discharge Mortality and Readmission Among Hospitalized Medicare Beneficiaries

BACKGROUND

Patients with dementia are frequently hospitalized and may face barriers in post-discharge care.

OBJECTIVE

To determine whether patients with dementia have an increased risk of adverse outcomes following discharge.

DESIGN

Retrospective cohort study.

SUBJECTS

Medicare beneficiaries hospitalized in 2016.

MAIN MEASURES

Co-primary outcomes were mortality and readmission within 30 days of discharge. Multivariable logistic regression models were estimated to assess the risk of each outcome for patients with and without dementia accounting for demographics, comorbidities, frailty, hospitalization factors, and disposition.

KEY RESULTS

The cohort included 1,089,109 hospitalizations of which 211,698 (19.3%) were of patients with diagnosed dementia (median (IQR) age 83 (76-89); 61.5% female) and 886,411 were of patients without dementia (median (IQR) age 76 (79-83); 55.0% female). At 30 days following discharge, 5.7% of patients with dementia had died compared to 3.1% of patients without dementia (adjusted odds ratio (aOR) 1.21; 95% CI 1.17 to 1.24). At 30 days following discharge, 17.7% of patients with dementia had been readmitted compared to 13.1% of patients without dementia (aOR 1.02; CI 1.002 to 1.04). Dementia was associated with an increased odds of readmission among patients discharged to the community (aOR 1.07, CI 1.05 to 1.09) but a decreased odds of readmission among patients discharge to nursing facilities (aOR 0.93, CI 0.90 to 0.95). Patients with dementia who were discharged to the community were more likely to be readmitted than those discharged to nursing facilities (18.9% vs 16.0%), and, when readmitted, were more likely to die during the readmission (20.7% vs 4.4%).

CONCLUSIONS

Diagnosed dementia was associated with a substantially increased risk of mortality and a modestly increased risk of readmission within 30 days of discharge. Patients with dementia discharged to the community had particularly elevated risk of adverse outcomes indicating possible gaps in post-discharge services and caregiver support.

Health service use before and after dementia diagnosis: a retrospective matched case-control study

OBJECTIVES

This study investigated patterns in health service usage among older adults with dementia and matched controls over a 10-year span from 5 years before until 5 years after diagnosis.

DESIGN

Population-based retrospective matched case-control study.

SETTING

Administrative health data of individuals in Saskatchewan, Canada from 1 April 2008 to 31 March 2019.

PARTICIPANTS

The study included 2024 adults aged 65 years and older living in the community at the time of dementia diagnosis from 1 April 2013 to 31 March 2014, matched 1:1 to individuals without a dementia diagnosis on age group, sex, rural versus urban residence, geographical region and comorbidity.

OUTCOME MEASURES

For each 5-year period before and after diagnosis, we examined usage of health services each year including family physician (FP) visits, specialist visits, hospital admissions, all-type prescription drug dispensations and short-term care admissions. We used negative binomial regression to estimate the effect of dementia on yearly average health service utilisation adjusting for sex, age group, rural versus urban residence, geographical region, 1 year prior health service use and comorbidity.

RESULTS

Adjusted findings demonstrated that 5 years before diagnosis, usage of all health services except hospitalisation was lower among persons with dementia than persons without dementia (all p<0.001). After this point, differences in higher health service usage among persons with dementia compared to without dementia were greatest in the year before and year after diagnosis. In the year before diagnosis, specialist visits were 59.7% higher (p<0.001) and hospitalisations 90.5% higher (p<0.001). In the year after diagnosis, FP visits were 70.0% higher (p<0.001) and all-type drug prescriptions 29.1% higher (p<0.001).

CONCLUSIONS

Findings suggest the year before and year after diagnosis offer multiple opportunities to implement quality supports. FPs are integral to dementia care and require effective resources to properly serve this population.

How Telemedicine Can Improve the Quality of Care for Patients with Alzheimer's Disease and Related Dementias? A Narrative Review

Background and Objectives: Dementia affects more than 55 million patients worldwide, with a significant societal, economic, and psychological impact. However, many patients with Alzheimer's disease (AD) and other related dementias have limited access to effective and individualized treatment. Care provision for dementia is often unequal, fragmented, and inefficient. The COVID-19 pandemic accelerated telemedicine use, which holds promising potential for addressing this important gap. In this narrative review, we aim to analyze and discuss how telemedicine can improve the quality of healthcare for AD and related dementias in a structured manner, based on the seven dimensions of healthcare quality defined by the World Health Organization (WHO), 2018: effectiveness, safety, people-centeredness, timeliness, equitability, integrated care, and efficiency. Materials and Methods: MEDLINE and Scopus databases were searched for peer-reviewed articles investigating the role of telemedicine in the quality of care for patients with dementia. A narrative synthesis was based on the seven WHO dimensions. Results: Most studies indicate that telemedicine is a valuable tool for AD and related dementias: it can improve effectiveness (better access to specialized care, accurate diagnosis, evidence-based treatment, avoidance of preventable hospitalizations), timeliness (reduction of waiting times and unnecessary transportation), patient-centeredness (personalized care for needs and values), safety (appropriate treatment, reduction of infection risk),integrated care (interdisciplinary approach through several dementia-related services), efficiency (mainly cost-effectiveness) and equitability (overcoming geographical barriers, cultural diversities). However, digital illiteracy, legal and organizational issues, as well as limited awareness, are significant potential barriers. Conclusions: Telemedicine may significantly improve all aspects of the quality of care for patients with dementia. However, future longitudinal studies with control groups including participants of a wide educational level spectrum will aid in our deeper understanding of the real impact of telemedicine in quality care for this population.

Alzheimer's Dementia After Exposure to Anesthesia and Surgery in the Elderly: A Matched Natural Experiment Using Appendicitis

OBJECTIVE

The aim of this study was to determine whether surgery and anesthesia in the elderly may promote Alzheimer disease and related dementias (ADRD).

BACKGROUND

There is a substantial conflicting literature concerning the hypothesis that surgery and anesthesia promotes ADRD. Much of the literature is confounded by indications for surgery or has small sample size. This study examines elderly patients with appendicitis, a common condition that strikes mostly at random after controlling for some known associations.

METHODS

A matched natural experiment of patients undergoing appendectomy for appendicitis versus control patients without appendicitis using Medicare data from 2002 to 2017, examining 54,996 patients without previous diagnoses of ADRD, cognitive impairment, or neurological degeneration, who developed appendicitis between ages 68 through 77 years and underwent an appendectomy (the ''Appendectomy'' treated group), matching them 5:1 to 274,980 controls, examining the subsequent hazard for developing ADRD.

RESULTS

The hazard ratio (HR) for developing ADRD or death was lower in the Appendectomy group than controls: HR = 0.96 [95% confidence interval (CI) 0.94-0.98], P < 0.0001, (28.2% in Appendectomy vs 29.1% in controls, at 7.5 years). The HR for death was 0.97 (95% CI 0.95-0.99), P = 0.002, (22.7% vs 23.1% at 7.5 years). The HR for developing ADRD alone was 0.89 (95% CI 0.86-0.92), P < 0.0001, (7.6% in Appendectomy vs 8.6% in controls, at 7.5 years). No subgroup analyses found significantly elevated rates of ADRD in the Appendectomy group.

CONCLUSION

In this natural experiment involving 329,976 elderly patients, exposure to appendectomy surgery and anesthesia did not increase the subsequent rate of ADRD.

The costs of treating all-cause dementia among American Indians and Alaska native adults who access services through the Indian Health Service and Tribal health programs

INTRODUCTION

Little is known about treatment costs for American Indian and Alaska Native (AI/AN) adults with dementia who access services through the Indian Health Service (IHS) and Tribal health programs.

METHODS

We analyzed fiscal year 2013 IHS/Tribal treatment costs for AI/ANs aged 65+ years with dementia and a matched sample without dementia (n = 1842) to report actual and adjusted total treatment costs and costs by service type. Adjusted costs were estimated using multivariable regressions.

RESULTS

Mean total treatment cost for adults with dementia were $13,027, $5400 higher than for adults without dementia ($7627). The difference in adjusted total treatment costs was $2943 (95% confidence interval [CI]: $1505, $4381), the majority of which was due to the difference in hospital inpatient costs ($2902; 95% CI: $1512, $4293).

DISCUSSION

Knowing treatment costs for AI/ANs with dementia can guide enhancements to policies and services for treating dementia and effectively using health resources.

Warning Signs of Acute Infectious Disease-Related Illness in Persons Living With Dementia: Perspectives of Primary Care Providers, Adult Day Service Center Staff, and Family Care Partners

In the current study, we conducted one-on-one interviews with primary care providers (PCPs) and family care partners (FCPs) and held focus groups with interdisciplinary adult day service center (ADSC) staff to understand the perspectives of care providers across community settings regarding early warning signs of acute illnesses in persons living with dementia (PLWD). We used content analysis to analyze qualitative data. Warning signs of acute illnesses in PLWD fell into one of five categories, including new onset changes in (a) physical functions, (b) moods or behaviors (psychological), (c) social interactions, (d) speech, or (e) appearance. FCPs (n = 11) focused on physical changes, whereas ADSC staff (n = 33) emphasized changes in speech and social interactions in addition to the other categories. Although ADSC staff and PCPs (n = 22) focused on changes in functions and moods, each group described these changes differently. ADSC staff possess rich information that can be used to identify acute changes in PLWD and describe a broader range of warning signs compared to PCPs and FCPs. FCPs may benefit from further training in distinguishing between normal disease progression and acute illness. Future research should focus on the implementation of standardized tools across community-based care providers to simplify the identification and reporting of early warning signs in PLWD.

Pad cultures: An ethnography of continence care and its consequences for people living with dementia during a hospital admission

BACKGROUND

There is little research examining how continence care is organised and delivered to people living with dementia across an acute hospital admission, despite the prevalence of this patient population and their vulnerability within these settings.

OBJECTIVE

To explore how continence care is delivered to people living with dementia during an acute hospital admission.

DESIGN

Ethnographic.

SETTING(S)

Acute medical units and wards within three hospitals across England and Wales.

PARTICIPANTS

People living with dementia and ward staff (registered nurses and care assistants) on participating wards.

METHODS

Ethnographic fieldwork collected over a period of 12 months (180 days of non-participant observation) focussing on the organisation and delivery of continence care to people living with dementia. Observations were supported with in situ ethnographic interviews (n = 562) with patients, visitors and staff within the six observed wards. Data collection and analysis drew on the theoretical sampling and constant comparison techniques of grounded theory.

RESULTS

The findings comprised of five overall themes: (1) visibility of continence; (2) rationales of continence care; (3) containment and contagion; (4) consequences of continence care and (5) supporting continence.

CONCLUSIONS

We introduce the term 'pad cultures' to refer to the established routine use of continence pads in the care of a wider group of people living with dementia (regardless of continence status and independence), with the rationale to provide safeguards, ensure containment and prevent 'accidents' or incontinent episodes. There was an expectation within acute wards that people living with dementia not only wear continence pads but that they also use them.

Effects of continuity of care on hospitalizations and healthcare costs in older adults with dementia

INTRODUCTION

People with dementia have high rates of hospitalization, and a share of these hospitalizations might be avoidable with appropriate ambulatory care, also known as potentially preventable hospitalization (PAH). This study investigates the associations between continuity of care and healthcare outcomes in the following year, including all-cause hospitalization, PAHs, and healthcare costs in patients with dementia.

METHODS

This is a longitudinal retrospective cohort study of 69,658 patients with dementia obtained from the Taiwan National Health Insurance Research Database. The Continuity of Care Index (COCI) was calculated to measure the continuity of dementia-related visits across physicians. The PAHs were classified into five types as defined by the Medicare Ambulatory Care Indicators for the Elderly (MACIEs). Logistic regression models were used to examine the effect of COCI on all-cause hospitalizations and PAHs, while generalized linear models were used to analyze the effect of COCI on outpatient, hospitalization, and total healthcare costs.

RESULTS

The high COCI group was significantly associated with a lower likelihood of all-cause hospitalization than the low COCI group (OR = 0.848, 95%CI: 0.821-0.875). The COCI had no significant effect on PAHs but was associated with lower outpatient costs (exp(β) = 0.960, 95%CI: 0.941 ~ 0.979), hospitalization costs (exp(β) = 0.663, 95%CI: 0.614 ~ 0.717), total healthcare costs (exp(β) = 0.962, 95%CI: 0.945-0.980).

CONCLUSION

Improving continuity of care for dementia-related outpatient visits is recommended to reduce hospitalization and healthcare costs, although there was no statistically significant effect of continuity of care found on PAHs.

Reasons for Hospitalization while Receiving Dementia Care Coordination through Maximizing Independence at Home

OBJECTIVES

Persons living with dementia (PLWD), particularly those with higher levels of functional impairment, are at increased risk of hospitalization and higher hospital-associated health care costs. Our objective was to provide a nuanced description of reasons for hospitalizations over a 12-month period among community-living persons with dementia taking part in a dementia care coordination study using caregiver-reported data and to describe how reasons varied by disease stage.

DESIGN

Retrospective descriptive analysis of pooled data from 2 concurrent studies of PLWD receiving the MIND at Home dementia care coordination program.

SETTING AND PARTICIPANTS

Four hundred ninety-four community-dwelling PLWD with a family caregiver in the Greater Baltimore and Central Maryland region, 2015‒2019.

METHODS

PLWD sociodemographic, clinical, functional, cognitive, and behavioral characteristics were assessed during an in-home baseline visit. Caregiver-reported hospitalizations and primary reasons for events were recorded every 4.5 months by research staff and by memory care coordinators during program delivery for a 12-month period. Hospitalization event data were subsequently reviewed, reconciled, and coded by a trained investigator.

RESULTS

One hundred seventy PLWD (34.4%) had at least 1 hospitalization within 12 months of enrollment, with 316 separate events. The most common primary reason for hospitalization according to caregivers was infection (22.4%), falls (16.5%), and cardiovascular/pulmonary (12.4%). Top reasons for hospitalization were falls among persons with mild and moderate functional impairment (17.7% and 21.9% respectively) and infection among PLWD with severe impairment (30.3%).

CONCLUSIONS AND IMPLICATIONS

Infections and falls were the most common caregiver-reported reasons for hospitalization in PLWD receiving dementia care coordination. Reasons for hospitalization varied based on severity of functional impairment. Greater understanding of reasons for hospitalization among PLWD receiving dementia care management interventions, from multiple important perspectives, may help programs more effectively address and prevent hospitalization.

Medicare spending associated with a dementia diagnosis among older adults

BACKGROUND

Over 6 million Americans have Alzheimer's Disease or Related Dementia (ADRD) but whether spikes in spending surrounding a new diagnosis reflect pre-diagnosis morbidity, diagnostic testing, or treatments for comorbidities is unknown.

METHODS

We used the 1998-2018 Health and Retirement Study and linked Medicare claims from older (≥65) adults to assess incremental quarterly spending changes just before versus just after a clinical diagnosis (diagnosis cohort, n = 2779) and, for comparative purposes, for a cohort screened as impaired based on the validated Telephone Interview for Cognitive Status (TICS) (impairment cohort, n = 2318). Models were adjusted for sociodemographic and health characteristics. Spending patterns were examined separately by sex, race, education, dual eligibility, and geography.

RESULTS

Among the diagnosis cohort, mean (SD) overall spending was $4773 ($9774) per quarter - 43% of which was spending on hospital care ($2048). In adjusted analyses, spending increased by $8400 (p < 0.001), or 156%, from $5394 in the quarter prior to $13,794 in the quarter including the diagnosis. Among the cohort in which impairment was incidentally detected using the TICS, adjusted spending did not change from just before to after detection of impairment, from $2986 before and $2962 after detection (p = 0.90). Incremental spending changes did not differ by sex, race, education, dual eligibility, or geography.

CONCLUSION

Large, transient spending increases accompany an ADRD diagnosis that may not be attributed to impairment or changes in functional status due to dementia. Further study may help reveal how treatment for comorbidities is associated with the clinical diagnosis of dementia, with potential implications for Medicare spending.

The combined effects of physical frailty and cognitive impairment on emergency department- versus direct-admission hospitalizations

BACKGROUND

We aimed to study whether physical frailty and cognitive impairment (CI) increase the risk of recurrent hospitalizations in older adults, independent of comorbidity, and disability.

METHODS

Two thousand five hundred forty-nine community-dwelling participants from the National Health and Aging Trends Study (NHATS) with 3 + years of continuous Medicare coverage from linked claims data were included. We used the marginal means/rates recurrent events model to investigate the association of baseline CI (mild CI or dementia) and physical frailty, separately and synergistically, with the number of all-source vs. Emergency Department (ED)-admission vs. direct admission hospitalizations over 2 years.

RESULTS

17.8% of participants had at least one ED-admission hospitalization; 12.7% had at least one direct admission hospitalization. Frailty and CI, modeled separately, were both significantly associated with risk of recurrent all-source (Rate Ratio (RR) = 1.24 for frailty, 1.21 for CI; p < .05) and ED-admission (RR = 1.49 for frailty, 1.41 for CI; p < .05) hospitalizations but not direct admission, adjusting for socio-demographics, obesity, comorbidity and disability. When CI and frailty were examined together, 64.3% had neither (Unimpaired); 28.1% CI only; 3.5% Frailty only; 4.1% CI + Frailty. Compared to those Unimpaired, CI alone and CI + Frailty were predictive of all-source (RR = 1.20, 1.48, p < .05) and ED-admission (RR = 1.36, 2.14, p < .05) hospitalizations, but not direct admission, in our adjusted model.

CONCLUSIONS

Older adults with both CI and frailty experienced the highest risk for recurrent ED-admission hospitalizations. Timely recognition of older adults with CI and frailty is needed, paying special attention to managing cognitive impairment to mitigate preventable causes of ED admissions and potentiate alternatives to hospitalization.

The Impact of Ambulatory Dementia Care Models on Hospitalization of Persons Living With Dementia: A Systematic Review

This systematic review presents an overview of the existing dementia care models in various ambulatory care settings under three categories (i.e., home- and community-based care models, partnership between health systems and community-based resources, and consultation models) and their impact on hospitalization among Persons Living with Dementia (PLWD). PRISMA guidelines were applied, and our search resulted in a total of 13 studies focusing on 11 care models. Seven studies reported that utilization of dementia care models was associated with a modest reduction in hospitalization among community-residing PLWD. Only two studies reported statistically significant results. Dementia care models that were utilized in specialty ambulatory care settings such as memory care showed more promising results than traditional primary care. To develop a better understanding of how dementia care models can be improved, future studies should explore how confounders (e.g., stage of dementia) influence hospitalization.

Reliability and Validity of the Neuropsychiatric Inventory-Questionnaire Using a Rasch Analysis

BACKGROUND AND PURPOSE

The purpose of this study was to expand on the limited psychometric testing of the NPI-Q, and extend testing to include hospitalized older adults.

METHOD

This was a descriptive study using data from 318 dyads in an ongoing cluster randomized clinical trial. Rasch analysis and hypothesis testing were done.

RESULTS

The majority of the participants were female (62%), non-Hispanic (98%), and black (50%) with a mean age of 81.62 (SD = 8.43). There was evidence of internal consistency and invariance across race and gender. The items fit with each subscale. Hypothesis testing was supported with a significant association between the NPI-Q and dementia and caregiver distress.

CONCLUSIONS

The NPI-Q is short, easy to complete, and reliable and valid when used with hospitalized older adults.

Risk factors for in-hospital death in elderly patients over 65 years of age with dementia: A retrospective cross-sectional study

As the population continues to age, dementia is becoming a huge social, economic, and healthcare burden. However, the risk factors for in-hospital death in elderly patients over 65 years of age with dementia are not well understood. Identifying factors that affect their prognosis could help clinicians with scientific decision-making. To examine the risk factors for in-hospital death in elderly patients over 65 years of age with dementia in the Geriatric Department of West China Hospital. In this retrospective, cross-sectional study, we analyzed inpatients aged ≥65 years with dementia between 2010 and 2016 using electronic medical records from the Information Center of West China Hospital. The risk factors for death were assessed using multivariable logistic regression. Out of a total of 2986 inpatients with dementia, 3.4% died. Patient deaths were related to digestive diseases, respiratory diseases, circulatory diseases, urinary diseases, and chronic obstructive pulmonary disease, whereas patient survival was associated with osteoporosis and Parkinson disease. Patients with a mean length of hospital stay of ≥60 days had an increased risk of death (all P <.05). In the multiple logistic regression analysis, age ≥80 years, digestive diseases, respiratory diseases, urinary diseases, diabetes, chronic obstructive pulmonary disease, and ≥7 comorbidities were risk factors for death. Mortality in hospitalized older patients with dementia is low, but some risk factors may be easily ignored. These findings could raise awareness among clinicians and caregivers about risk factors in hospitalized older patients, particularly hospitalized elderly patients with multiple comorbidities. Therefore, to reduce mortality, early prevention and management of potential risks are necessary.

Frequency of Neurological Diseases After COVID-19, Influenza A/B and Bacterial Pneumonia

Introduction

COVID-19 might affect the incidence of specific neurological diseases, but it is unknown if this differs from the risk following other infections. Here, we characterized the frequency of neurodegenerative, cerebrovascular, and immune-mediated neurological diseases after COVID-19 compared to individuals without COVID-19 and those with other respiratory tract infections.

Methods

This population-based cohort study utilized electronic health records covering ~50% of Denmark's population (n = 2,972,192). Between 02/2020 and 11/2021, we included individuals tested for COVID-19 or diagnosed with community-acquired bacterial pneumonia in hospital-based facilities. Additionally, we included individuals tested for influenza in the corresponding pre-pandemic period between 02/ 2018 and 11/2019. We stratified cohorts for in- and outpatient status, age, sex, and comorbidities.

Results

In total, 919,731 individuals were tested for COVID-19, of whom 43,375 tested positive (35,362 outpatients, 8,013 inpatients). Compared to COVID-negative outpatients, COVID-19 positive outpatients had an increased RR of Alzheimer's disease (RR = 3.5; 95%CI: 2.2–5.5) and Parkinson's disease (RR = 2.6; 95%CI: 1.7–4.0), ischemic stroke (RR = 2.7; 95%CI: 2.3–3.2) and intracerebral hemorrhage (RR = 4.8; 95%CI: 1.8–12.9). However, when comparing to other respiratory tract infections, only the RR for ischemic stroke was increased among inpatients with COVID-19 when comparing to inpatients with influenza (RR = 1.7; 95%CI: 1.2–2.4) and only for those &gt;80 years of age when comparing to inpatients with bacterial pneumonia (RR = 2.7; 95%CI: 1.2–6.2). Frequencies of multiple sclerosis, myasthenia gravis, Guillain-Barré syndrome and narcolepsy did not differ after COVID-19, influenza and bacterial pneumonia.

Conclusion

The risk of neurodegenerative and cerebrovascular, but not neuroimmune, disorders was increased among COVID-19 positive outpatients compared to COVID-negative outpatients. However, except for ischemic stroke, most neurological disorders were not more frequent after COVID-19 than after other respiratory infections.

Multimorbidity patterns in adult day health center clients with dementia: a latent class analysis

BACKGROUND

Persons living with dementia (PLWD) in adult day centers (ADCs) represent a complex and vulnerable population whose well-being is at risk based on numerous factors. Greater knowledge of the interaction between dementia, chronic conditions, and social determinants of health would enable ADCs to identify and target the use of their resources to better support clients in need of in-depth intervention. The purpose of this paper is to (a) classify PLWD in ADCs according to their level of medical complexity and (b) identify the demographic, functional, and clinical characteristics of those with the highest degree of medical complexity.

METHODS

This was a secondary data analysis of 3052 clients with a dementia diagnosis from 53 ADCs across the state of California between 2012 and 2019. The most common diagnosis codes were organized into 28 disease categories to enable a latent class analysis (LCA). Chi-square test, analysis of variance (ANOVA), and Kruskal-Wallis tests were conducted to examine differences among latent classes with respect to clinical and functional characteristics.

RESULTS

An optimal 4-class solution was chosen to reflect chronic conditions among PLWD: high medical complexity, moderate medical complexity, low medical complexity, and no medical complexity. Those in the high medical complexity were taking an average of 12.72 (+/- 6.52) medications and attending the ADC an average of 3.98 days (+/- 1.31) per week-values that exceeded any other class. They also experienced hospitalizations more than any other group (19.0%) and met requirements for the nursing facility level of care (77.4%). In addition, the group experienced the greatest frequency of bladder (57.5%) and bowel (15.7%) incontinence.

CONCLUSIONS

Our results illustrate a high degree of medical complexity among PLWD in ADCs. A majority of PLWD not only have multimorbidity but are socially disadvantaged. Our results demonstrate that a comprehensive multidisciplinary approach that involves community partners such as ADCs is critically needed that addresses functional decline, loneliness, social isolation, and multimorbidity which can negatively impact PLWD.

Identifying patterns of potentially preventable hospitalisations in people living with dementia

BACKGROUND

Older Australians make up 46% of all potentially preventable hospitalisations (PPHs) and people living with dementia are at significantly greater risk. While policy reforms aim to reduce PPHs, there is currently little evidence available on what drives this, especially for people living with dementia. This study examines patterns of PPHs in people living with dementia to inform service delivery and the development of evidence-based interventions.

METHODS

We used the Victorian Admitted Episodes Dataset from Victoria, Australia, to extract data for people aged 50 and over with a diagnosis of dementia between 2015 and 2016. Potentially avoidable admissions, known as ambulatory care sensitive conditions (ACSCs), were identified. The chi-square test was used to detect differences between admissions for ACSCs and non-ACSCs by demographic, geographical, and administrative factors. Predictors of ACSCs admissions were analysed using univariate and multiple logistic regression.

RESULTS

Of the 8156 hospital records, there were 3884 (48%) ACSCs admissions, of which admissions for urinary tract infections accounted for 31%, followed by diabetes complications (21%). Mean bed-days were 8.26 for non-ACSCs compared with 9.74 for ACSCs (p ≤ 0.001). There were no differences between admissions for ACSCs and non-ACSCs by sex, marital status, region (rural vs metro), and admission source (private accommodation vs residential facility). Culture and language predicted ASCS admission rates in the univariate regression analyses, with ACSC admission rates increasing by 20 and 29% if English was not the preferred language or if an interpreter was required, respectively. Results from the multiple regression analysis confirmed that language was a significant predictor of ACSC admission rates.

CONCLUSIONS

Improved primary health care may help to reduce the most common causes of PPHs for people living with dementia, particularly for those from culturally and linguistically diverse backgrounds.

The National Partnership to Improve Dementia Care and Hospital Readmission Among Skilled Nursing Facility Residents

The National Partnership to Improve Dementia Care in Nursing Homes (i.e., the National Partnership) was launched in March 2012. Using national Medicare, Minimum Data Set, and Nursing Home Compare data in CY 2010-2014, we examined changes in hospital readmissions for older post-acute skilled nursing facility (SNF) residents with Alzheimer's disease or related dementias (ADRD) following the National Partnership. Using residents without ADRD as reference group to control for concurrent policy and SNF quality changes, we estimated linear probability models to examine the relationship between readmissions and the National Partnership for residents with ADRD, and also stratified the analysis by quality of SNFs. We found a decreasing trend in hospital readmissions over time. The risk of readmissions in residents with ADRD decreased additional 0.3 percentage-points (p < .01) after the launch of the National Partnership. This relationship varied across SNFs with different quality, as it was stronger in high-quality compared to low-quality SNFs.

[Mortality in patients with dementia admitted in critical care units]

OBJECTIVE

To determine the mortality and comorbidities associated of patients with dementia admitted to the Intensive Care Unit (ICU) on the hospitalization and at one year of follow-up.

MATERIALS AND METHODS

A retrospective observational cohort study was carried out between 2012 and 2017 at the Hospital Italiano de San Justo, of patients who were admitted to the ICU, these were observed up to hospitalary death, out hospital death one year of hospitalization, the disenrollment from the institution's health plan or the end of the follow-up.

RESULTS

A total of 163 patients were included for analysis. We recorded those 79 patients (48.47%) died one year after the hospitalization, of them 25 (15.34%) in ICU and 8 (4.91%) in general room. The most frequent causes of death were respiratory. The factors most associated with mortality were: orotracheal intubation (HR=2.01; 95% CI: 1.11-3.65; P=.02), history of leukemia (HR=8.55; 95% CI: 1.82-40.05; P≤.05), elevated Charlson (HR=1.16, 95% CI: 1.04-1.41; P=.05), and elevated APACHE II at admission (HR=1.07; 95% CI: 1.03-1.11; P≤.05).

CONCLUSIONS

The present study expresses the prognosis of patients with a diagnosis of dementia admitted to the ICU and that depends not only on their baseline neurological status but also on the severity at admission and comorbidities.

Incidence of potentially disruptive medical and social events in older adults with and without dementia

BACKGROUND

Potentially disruptive medical, surgical, and social events-such as pneumonia, hip fracture, and widowhood-may accelerate the trajectory of decline and impact caregiving needs in older adults, especially among people with dementia (PWD). Prior research has focused primarily on nursing home residents with dementia. We sought to assess the incidence of potentially disruptive events in community-dwelling people with and without dementia.

METHODS

Retrospective cohort study of participants aged 65+ enrolled in the Health and Retirement Study between 2010 and 2018 (n = 9346), including a subset who were married-partnered at baseline (n = 5105). Dementia was defined with a previously validated algorithm. We calculated age-adjusted and gender-stratified incidence per 1000 person-years and incidence rate ratios of: 1) hospitalization for pneumonia, 2) hip fracture, and 3) widowhood in people with and without dementia.

RESULTS

PWD (n = 596) were older (mean age 84 vs. 75) and a higher proportion were female (67% vs. 57%) than people without dementia (PWoD) (n = 8750). Age-adjusted incidence rates (per 1000 person-years) of pneumonia were higher in PWD (113.1; 95% CI 94.3, 131.9) compared to PWoD (62.1; 95% CI 54.7, 69.5), as were hip fractures (12.3; 95% CI 9.1, 15.6 for PWD compared to 8.1; 95% CI 6.9, 9.2 in PWoD). Point estimates of widowhood incidence were slightly higher for PWD (25.3; 95% CI 20.1, 30.5) compared to PWoD (21.9; 95% CI 20.3, 23.5), but differences were not statistically significant. The association of dementia with hip fracture-but not pneumonia or widowhood-was modified by gender (male incidence rate ratio [IRR] 2.24, 95% CI 1.34, 3.75 versus female IRR 1.31 95% CI 0.92,1.86); interaction term p = 0.02).

CONCLUSIONS

Compared to PWoD, community-dwelling PWD had higher rates of pneumonia and hip fracture, but not widowhood. Knowing how often PWD experience these events can aid in anticipatory guidance and care planning for this growing population.

Patterns of unplanned hospital admissions among people with dementia: from diagnosis to the end of life

BACKGROUND

hospitalisations are sentinel events for people with dementia. How patterns of unplanned hospital admissions change among people with dementia after diagnosis is relatively unknown.

OBJECTIVE

to describe patterns of unplanned hospital admissions of people with dementia from diagnosis until death/study end.

METHODS

retrospective cohort study using mental healthcare provider data of people diagnosed with dementia in London, UK (1995-2017), linked to mortality and hospital data. The primary outcome was the rate of unplanned hospital admissions after diagnosis until death/study end. We calculated the cumulative incidence of unplanned hospital admissions. The rates of unplanned hospital admissions and the percentage of time spent as an inpatient were stratified by time from first dementia diagnosis.

RESULTS

for 19,221 people with dementia (61.4% female, mean age at diagnosis 81.0 years (standard deviation, SD 8.5)), the cumulative incidence of unplanned hospital admissions (n = 14,759) was 76.8% (95% CI 76.3%-77.3%). Individuals remained in the study for mean 3.0 (SD 2.6) years, and 12,667 (65.9%) died. Rates and lengths of unplanned hospital admissions remained relatively low and short in the months after the dementia diagnosis, increasing only as people approached the end of life. Percentage of time spent as an inpatient was <3% for people who were alive at the study end but was on average 19.6 and 13.3% for the decedents in the last 6 and 12 months of life, respectively.

CONCLUSIONS

the steep rise in hospitalisations before death highlights the need for improved community care and services for people with dementia who are approaching the end of life.

Peripheral Pathways to Neurovascular Unit Dysfunction, Cognitive Impairment, and Alzheimer’s Disease

Alzheimer’s disease (AD) is the most common form of dementia. It was first described more than a century ago, and scientists are acquiring new data and learning novel information about the disease every day. Although there are nuances and details continuously being unraveled, many key players were identified in the early 1900’s by Dr. Oskar Fischer and Dr. Alois Alzheimer, including amyloid-beta (Aβ), tau, vascular abnormalities, gliosis, and a possible role of infections. More recently, there has been growing interest in and appreciation for neurovascular unit dysfunction that occurs early in mild cognitive impairment (MCI) before and independent of Aβ and tau brain accumulation. In the last decade, evidence that Aβ and tau oligomers are antimicrobial peptides generated in response to infection has expanded our knowledge and challenged preconceived notions. The concept that pathogenic germs cause infections generating an innate immune response (e.g., Aβ and tau produced by peripheral organs) that is associated with incident dementia is worthwhile considering in the context of sporadic AD with an unknown root cause. Therefore, the peripheral amyloid hypothesis to cognitive impairment and AD is proposed and remains to be vetted by future research. Meanwhile, humans remain complex variable organisms with individual risk factors that define their immune status, neurovascular function, and neuronal plasticity. In this focused review, the idea that infections and organ dysfunction contribute to Alzheimer’s disease, through the generation of peripheral amyloids and/or neurovascular unit dysfunction will be explored and discussed. Ultimately, many questions remain to be answered and critical areas of future exploration are highlighted.

Potentially avoidable causes of hospitalisation in people with dementia: contemporaneous associations by stage of dementia in a South London clinical cohort

OBJECTIVES

To estimate the frequency of all-cause and ambulatory care sensitive condition (ACSCs)-related hospitalisations among individuals with dementia. In addition, to investigate differences by stage of dementia based on recorded cognitive function.

SETTING

Data from a large London dementia care clinical case register, linked to a national hospitalisation database.

PARTICIPANTS

Individuals aged ≥65 years with a confirmed dementia diagnosis with recorded cognitive function.

OUTCOME MEASURES

Acute general hospital admissions were evaluated within 6 months of a randomly selected cognitive function score in patients with a clinical diagnosis of dementia. To evaluate associations between ACSC-related hospital admissions (overall and individual ACSCs) and stage of dementia, an ordinal regression was performed, modelling stage of dementia as the dependant variable (to facilitate efficient model selection, with no implication concerning the direction of causality).

RESULTS

Of the 5294 people with dementia, 2993 (56.5%) had at least one hospitalisation during a 12-month period of evaluation, and 1192 (22.5%) had an ACSC-related admission. Proportions with an all-cause or ACSC-related hospitalisation were greater in the groups with more advanced dementia (all-cause 53.9%, 57.1% and 60.9%, p 0.002; ACSC-related 19.5%, 24.0% and 25.3%, p<0.0001 in the mild, moderate and severe groups, respectively). An ACSC-related admission was associated with 1.3-fold (95% CI 1.1 to 1.5) increased odds of more severe dementia after adjusting for demographic factors. Concerning admissions for individual ACSCs, the most common ACSC was urinary tract infection /pyelonephritis (9.8% of hospitalised patients) followed by pneumonia (7.1%); in an adjusted model, these were each associated with 1.4-fold increased odds of more severe dementia (95% CI 1.2 to 1.7 and 1.1 to 1.7, respectively).

CONCLUSIONS

Potentially avoidable hospitalisations were common in people with dementia, particularly in those with greater cognitive impairment. Our results call for greater attention to the extent of cognitive status impairment, and not just dementia diagnosis, when evaluating measures to reduce the risk of potentially avoidable hospitalisations.

Dementia-friendly intervention for hospitalized older adults with cognitive impairments: results of the Italian Dementia-Friendly Hospital Trial (IDENTITÀ)

Objective: To evaluate whether a short training focused on improving dementia care practices of the hospital staff was able to counteract functional loss and to decrease negative outcomes at discharge among hospitalized older adults with cognitive impairment.Method: Sixty-eight hospitalized participants aged 65 and over with cognitive impairment were included in the study, allocated in the control group (n = 34) and intervention group (n = 34). The intervention consisted of a short training of the hospital staff aimed at improving the management of patients with cognitive impairment. Participants were evaluated within 48 h of hospital admission and at discharge using a battery of tests including Barthel Index, Mini-Mental State Examination, and Hospital Anxiety and Depression Scale.Results: The intervention group demonstrated shorter hospital length of stay and a maintenance of the functional status at discharge compared to the control group. We observed no differences in cognitive ability between the two groups, and a trend towards a decrease of anxious symptoms in the intervention group compared to the control group.Conclusion: The results suggest that an intervention, focused on improving dementia care practices in healthcare staff, has the potential to improve the outcomes for hospitalized older adults with cognitive impairment.

Dementia diagnosis and utilization patterns in a racially diverse population within an integrated health care delivery system

Introduction

In an effort to identify improvement opportunities for earlier dementia detection and care within a large, integrated health care system serving diverse Medicare Advantage (MA) beneficiaries, we examined where, when, and by whom Alzheimer's disease and related dementias (ADRD) diagnoses are recorded as well as downstream health care utilization and life care planning.

Methods

Patients 65 years and older, continuously enrolled in the Kaiser Foundation health plan for at least 2 years, and with a first ADRD diagnosis between January 1, 2015, and December 31, 2018, comprised the incident cohort. Electronic health record data were used to identify site and source of the initial diagnosis (clinic vs hospital-based, provider type), health care utilization in the year before and after diagnosis, and end-of-life care.

Results

ADRD prevalence was 5.5%. A total of 25,278 individuals had an incident ADRD code (rate: 1.2%) over the study period-nearly half during a hospital-based encounter. Hospital-diagnosed patients had higher comorbidities, acute care use before and after diagnosis, and 1-year mortality than clinic-diagnosed individuals (36% vs 11%). Many decedents (58%-72%) received palliative care or hospice. Of the 55% diagnosed as outpatients, nearly two-thirds were diagnosed by dementia specialists; when used, standardized cognitive assessments indicated moderate stage ADRD. Despite increases in advance care planning and visits to dementia specialists in the year after diagnosis, acute care use also increased for both clinic- and hospital-diagnosed cohorts.

Discussion

Similar to other MA plans, ADRD is under-diagnosed in this health system, compared to traditional Medicare, and diagnosed well beyond the early stages, when opportunities to improve overall outcomes are presumed to be better. Dementia specialists function primarily as consultants whose care does not appear to mitigate acute care use. Strategic targets for ADRD care improvement could focus on generating pragmatic evidence on the value of proactive detection and tracking, care planning, and the role of specialists in chronic care management.

The Revised Medical Care Act is associated with a decrease in hospital death for the total Japanese older adult population regardless of dementia status: An interrupted time series analysis

Background

In 2006, Japan introduced the Revised Medical Care Act aimed to shift end-of-life care from hospitals to communities. For patients and families, dying in hospital can be highly distressing. Persons with dementia are especially susceptible to negative hospital-related outcomes. This study aims to evaluate whether the Revised Medical Care Act is associated with a decrease in the proportion of hospital deaths for older adults and persons with dementia over a 20-year period covering the reform.

Methods and findings

This is a population-level, repeated cross-sectional study using mortality data from Vital Statistics Japan. Participants were Japanese older adults 65 years or older with and without dementia who died between 1996 and 2016. The policy intervention was the 2006 Revised Medical Care Act that increased community care infrastructure. The primary outcome was location of death in hospital, nursing home, home, or elsewhere. The trend in the proportion of location of death, before and after the reforms was estimated using an interrupted time-series analysis. All analyses were adjusted for sex and seasonality. Of the 19,307,104 older adult decedents, 216,442 had dementia identified on their death certificate. Death in nursing home (1.10, 95% CI 1.10–1.10), home (1.08, 95% CI 1.08–1.08), and elsewhere (1.07, 95% CI 1.07–1.07) increased over time compared to hospital deaths for the total population after reform implementation. Nursing home (1.04, 95% CI 1.03–1.05) and home death (1.11, 95% CI 1.10–1.12) increased after reform implementation for persons with dementia.

Conclusion

This study provides evidence that the 2006 Revised Medical Care Act was associated with decreased older adults dying in hospital regardless of dementia status; however, hospital continues as the primary location of death.

Standardized assessment of cognitive function of post-acute care patients

BACKGROUND

The assessment of cognitive function in post-acute care (PAC) settings is important for understanding an individual's condition and care needs, developing better person-directed care plans, predicting resource needs and understanding case mix. Therefore, we tested the feasibility and reliability of cognitive function assessments, including the Brief Interview for Mental Status (BIMS), Confusion Assessment Method (CAM©), Expression and Understanding, and Behavioral Signs and Symptoms for patients in PAC under the intent of the IMPACT Act of 2014.

METHODS

We conducted a national test of assessments of four standardized cognitive function data elements among patients in PAC. One hundred and forty-three PAC settings (57 home health agencies, 28 inpatient rehabilitation facilities, 28 long-term care hospitals, and 73 Skilled Nursing Facilities) across 14 U.S. markets from November 2017 to August 2018. At least one of four cognitive function data elements were assessed in 3026 patients. We assessed descriptive statistics, percent of missing data, time to complete, and interrater reliability between paired research nurse and facility staff assessors, and assessor feedback.

RESULTS

The BIMS, CAM©, Expression and Understanding, and Behavioral Signs and Symptoms demonstrated low rates of missing data (less than 2%), high percent agreement, and substantial support from assessors. The prevalence of Behavioral Signs and Symptoms was low in our sample of PAC settings.

CONCLUSION

Findings provide support for feasibility of implementing standardized assessment of all our cognitive function data elements for patients in PAC settings. The BIMS and CAM© were adopted into federal Quality Reporting Programs in the fiscal year/calendar year 2020 final rules. Future work could consider implementing additional cognitive items that assess areas not covered by the BIMS and CAM©.

Determinants of emergency department utilisation by older adults in Singapore: A systematic review

INTRODUCTION

Adults aged ≥60 years contribute to disproportionately higher visits to the emergency departments (ED). We performed a systematic review to examine the reasons why older persons visit the ED in Singapore.

METHODS

We searched Medline, Embase and Scopus from January 2000 to December 2021 for studies reporting on ED utilisation by older adults in Singapore, and included studies that investigated determinants of ED utilisation. Statistically significant determinants and their effect sizes were extracted. Determinants of ED utilisation were organised using Andersen and Newman's model. Quality of studies was evaluated using Newcastle Ottawa Scale and Critical Appraisal Skills Programme.

RESULTS

The search yielded 138 articles, of which 7 were used for analysis. Among the significant individual determinants were predisposing (staying in public rental housing, religiosity, loneliness, poorer coping), enabling (caregiver distress from behavioural and psychological symptoms of dementia) and health factors (multimorbidity in patients with dementia, frailty, primary care visit in last 6 months, better treatment adherence). The 7 included studies are of moderate quality and none of them employed conceptual frameworks to organise determinants of ED utilisation.

CONCLUSION

The major determinants of ED utilisation by older adults in Singapore were largely individual factors. Evaluation of societal determinants of ED utilisation was lacking in the included studies. There is a need for a more holistic examination of determinants of ED utilisation locally based on conceptual models of health seeking behaviours.

Heart Disease and Stroke Statistics-2022 Update: A Report From the American Heart Association

BACKGROUND

The American Heart Association, in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2022 Statistical Update is the product of a full year's worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes data on the monitoring and benefits of cardiovascular health in the population and an enhanced focus on social determinants of health, adverse pregnancy outcomes, vascular contributions to brain health, and the global burden of cardiovascular disease and healthy life expectancy.

RESULTS

Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Acute care utilization risk among older adults living undiagnosed or unaware of dementia

BACKGROUND

Dementia is associated with increased risk of hospitalization and emergency department (ED) visits. Many persons with dementia are undiagnosed or unaware of their diagnosis, however. Our objective was to determine whether undiagnosed dementia or unawareness affects risk of hospitalization or ED visits.

METHODS

Retrospective longitudinal cohort study of 3537 community-living adults age ≥65 enrolled in the 2011-2017 National Health and Aging Trends Study with linked fee-for-service Medicare claims. Using self or proxy reported diagnosis, proxy dementia screening questionnaire, cognitive testing, and Medicare claims diagnosis, participants were classified as having (1) no dementia or dementia, for which they were classified as (2) undiagnosed, (3) diagnosed but unaware, or (4) diagnosed and aware. Proportional hazards models evaluated all-cause and potentially preventable hospitalization and ED visit risk by time-varying dementia status, adjusting for older adult characteristics.

RESULTS

Most participants (n = 2879) had no dementia at baseline. Among participants with dementia at baseline (n = 658), 187 were undiagnosed, 300 diagnosed but unaware, and 171 diagnosed and aware. In multivariable adjusted proportional hazards models, persons with undiagnosed dementia had lower risk of hospitalization and ED visits compared to persons diagnosed and aware (all-cause hospitalization aHR 0.59 [0.44, 0.79] and ED visit aHR 0.63 [0.47, 0.85]) and similar risks of these outcomes compared to persons without dementia. Individuals diagnosed but unaware had greater risk compared to those without dementia: aHR 1.37 (1.18, 1.59) for all-cause hospitalization and 1.48 (1.28, 1.71) for ED visits; they experienced risk comparable to individuals diagnosed and aware.

CONCLUSION

Older adults with undiagnosed dementia are not at increased risk of acute care utilization after accounting for differences in other characteristics. Individuals unaware of diagnosed dementia demonstrate risk similar to individuals aware of the diagnosis. Increasing diagnosis alone may not affect acute care utilization. The role of awareness warrants further investigation.

Estimation of the global prevalence of dementia in 2019 and forecasted prevalence in 2050: an analysis for the Global Burden of Disease Study 2019

BACKGROUND

Given the projected trends in population ageing and population growth, the number of people with dementia is expected to increase. In addition, strong evidence has emerged supporting the importance of potentially modifiable risk factors for dementia. Characterising the distribution and magnitude of anticipated growth is crucial for public health planning and resource prioritisation. This study aimed to improve on previous forecasts of dementia prevalence by producing country-level estimates and incorporating information on selected risk factors.

METHODS

We forecasted the prevalence of dementia attributable to the three dementia risk factors included in the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 (high body-mass index, high fasting plasma glucose, and smoking) from 2019 to 2050, using relative risks and forecasted risk factor prevalence to predict GBD risk-attributable prevalence in 2050 globally and by world region and country. Using linear regression models with education included as an additional predictor, we then forecasted the prevalence of dementia not attributable to GBD risks. To assess the relative contribution of future trends in GBD risk factors, education, population growth, and population ageing, we did a decomposition analysis.

FINDINGS

We estimated that the number of people with dementia would increase from 57·4 (95% uncertainty interval 50·4-65·1) million cases globally in 2019 to 152·8 (130·8-175·9) million cases in 2050. Despite large increases in the projected number of people living with dementia, age-standardised both-sex prevalence remained stable between 2019 and 2050 (global percentage change of 0·1% [-7·5 to 10·8]). We estimated that there were more women with dementia than men with dementia globally in 2019 (female-to-male ratio of 1·69 [1·64-1·73]), and we expect this pattern to continue to 2050 (female-to-male ratio of 1·67 [1·52-1·85]). There was geographical heterogeneity in the projected increases across countries and regions, with the smallest percentage changes in the number of projected dementia cases in high-income Asia Pacific (53% [41-67]) and western Europe (74% [58-90]), and the largest in north Africa and the Middle East (367% [329-403]) and eastern sub-Saharan Africa (357% [323-395]). Projected increases in cases could largely be attributed to population growth and population ageing, although their relative importance varied by world region, with population growth contributing most to the increases in sub-Saharan Africa and population ageing contributing most to the increases in east Asia.

INTERPRETATION

Growth in the number of individuals living with dementia underscores the need for public health planning efforts and policy to address the needs of this group. Country-level estimates can be used to inform national planning efforts and decisions. Multifaceted approaches, including scaling up interventions to address modifiable risk factors and investing in research on biological mechanisms, will be key in addressing the expected increases in the number of individuals affected by dementia.

Lessons from Detecting Cognitive Impairment Including Dementia (DetectCID) in Primary Care

Background: Cognitive impairment, including dementia, is frequently under-detected in primary care. The Consortium for Detecting Cognitive Impairment, including Dementia (DetectCID) convenes three multidisciplinary teams that are testing novel paradigms to improve the frequency and quality of patient evaluations for detecting cognitive impairment in primary care and appropriate follow-up. Objective: Our objective was to characterize the three paradigms, including similarities and differences, and to identify common key lessons from implementation. Methods: A qualitative evaluation study with dementia specialists who were implementing the detection paradigms. Data was analyzed using content analysis. Results: We identified core components of each paradigm. Key lessons emphasized the importance of engaging primary care teams, enabling primary care providers to diagnose cognitive disorders and provide ongoing care support, integrating with the electronic health record, and ensuring that paradigms address the needs of diverse populations. Conclusion: Approaches are needed that address the arc of care from identifying a concern to post-diagnostic management, are efficient and adaptable to primary care workflows, and address a diverse aging population. Our work highlights approaches to partnering with primary care that could be useful across specialties and paves the way for developing future paradigms that improve differential diagnosis of symptomatic cognitive impairment, identifying not only its presence but also its specific syndrome or etiology.

Written discharge communication of diagnostic and decision-making information for persons living with dementia during hospital to skilled nursing facility transitions

Hospital-to-skilled nursing facility (SNF) transitions constitute a vulnerable point in care for people with dementia and often precede important care decisions. These decisions necessitate accurate diagnostic/decision-making information, including dementia diagnosis, power of attorney for health care (POAHC), and code status; however, inter-setting communication during hospital-to-SNF transitions is suboptimal. This retrospective cohort study examined omissions of diagnostic/decision-making information in written discharge communication during hospital-to-SNF transitions. Omission rates were 22% for dementia diagnosis, 82% and 88% for POAHC and POAHC activation respectively, and 70% for code status. Findings highlight the need to clarify and intervene upon causes of hospital-to-SNF communication gaps.

[Place of death of older people with dementia : Epidemiological data from an observational study of places of death in Germany (2001, 2011, 2017)]

BACKGROUND

Dementia is increasingly perceived as a terminal illness due to disease progression with a shortened life expectancy and often a lack of therapeutic options. In the context of palliative care, the preferred place of death is considered a quality indicator for needs-based patient care. The aim of this study was to describe the distribution of places of death of older patients with dementia.

MATERIAL AND METHODS

Death certificates from the years 2001, 2011 and 2017 were evaluated from the most comprehensive study on places of death in Germany to date, conducted in selected regions of Westphalia. Medical information on the cause of death was also analyzed. In this way, deceased patients with dementia ≥ 65 years (ICD-10: F01, F02, F03, G30) were identified and the distribution of their places of death statistically determined.

RESULTS

Dementia was present in 4720 out of 31,631 (14.9%; 95% CI: 14.5-15.3%) deceased patients ≥ 65 years. The distribution of places of death was as follows (%; age-standardized; 2001/2011/2017): home environment 24.0/19.7/15.8, hospital 40.4/29.0/24.3, palliative care unit 0.0/0.3/1.8, hospice 0.4/0.9/0.9, nursing home 35.2/49.5/57.1 and other places 0.0/0.0/0.0.

CONCLUSION

The majority of older patients (≥ 65 years) with dementia die in nursing homes, followed by hospitals and the home environment. Palliative care units and hospices play a subordinate role as places of death for patients with dementia.

Dementia caregiving across Latin America and the Caribbean and brain health diplomacy

The prevalence of dementia in Latin America and the Caribbean is growing rapidly, increasing the burden placed on caregivers. Exacerbated by fragile health-care systems, unstable economies, and extensive inequalities, caregiver burden in this region is among the highest in the world. We reviewed the major challenges to caregiving in Latin America and the Caribbean, and we propose regional and coordinated actions to drive future change. Current challenges include the scarcity of formal long-term care, socioeconomic and social determinants of health disparities, gender-biased burdens, growing dementia prevalence, and the effect of the current COVID-19 pandemic on families affected by dementia. Firstly, we propose local and regional short-term strategic recommendations, including systematic identification of specific caregiver needs, testing of evidence-based local interventions, contextual adaptation of strategies to different settings and cultures, countering gender bias, strengthening community support, provision of basic technology, and better use of available information and communications technology. Additionally, we propose brain health diplomacy (ie, global actions aimed to overcome the systemic challenges to brain health by bridging disciplines and sectors) and convergence science as frameworks for long-term coordinated responses, integrating tools, knowledge, and strategies to expand access to digital technology and develop collaborative models of care. Addressing the vast inequalities in dementia caregiving across Latin America and the Caribbean requires innovative, evidence-based solutions coordinated with the strengthening of public policies.

Avoidable Hospitalizations in Persons with Dementia: a Population-Wide Descriptive Study (2000-2015)

Background

Whether avoidable hospitalizations in community-dwelling persons with dementia have decreased during primary care reforms is unknown.

Methods

We described the prevalence and trends in avoidable hospitalizations in population-based repeated yearly cohorts of 192,144 community-dwelling persons with incident dementia (Quebec, 2000-2015) in the context of a province-wide primary care reform, using the provincial health administrative database.

Results

Trends in both types of Ambulatory Care Sensitive Condition (ACSC) hospitalization (general and older population) and 30-day readmission rates remained constant with average rates per 100 person-years: 20.5 (19.9-21.1), 31.7 (31.0-32.4), 20.6 (20.1-21.2), respectively. Rates of delayed hospital discharge (i.e., alternate level of care (ALC) hospitalizations) decreased from 23.8 (21.1-26.9) to 17.9 (16.1-20.1) (relative change -24.6%).

Conclusions

These figures shed light on the importance of the phenomenon, its lack of improvement for most outcomes over the years, and the need to develop evidence-based policies to prevent avoidable hospitalizations in this vulnerable population.

Exposure to Air Pollution in Relation to Risk of Dementia and Related Outcomes: An Updated Systematic Review of the Epidemiological Literature

BACKGROUND

Dementia is a devastating neurologic condition that is common in older adults. We previously reviewed the epidemiological evidence examining the hypothesis that long-term exposure to air pollution affects dementia risk. Since then, the evidence base has expanded rapidly.

OBJECTIVES

With this update, we collectively review new and previously identified epidemiological studies on air pollution and late-life cognitive health, highlighting new developments and critically discussing the merits of the evidence.

METHODS

Using a registered protocol (PROSPERO 2020 CRD42020152943), we updated our literature review to capture studies published through 31 December 2020, extracted data, and conducted a bias assessment.

RESULTS

We identified 66 papers (49 new) for inclusion in this review. Cognitive level remained the most commonly considered outcome, and particulate matter (PM) remained the most commonly considered air pollutant. Since our prior review, exposure estimation methods in this research have improved, and more papers have looked at cognitive change, neuroimaging, and incident cognitive impairment/dementia, though methodological concerns remain common. Many studies continue to rely on administrative records to ascertain dementia, have high potential for selection bias, and adjust for putative mediating factors in primary models. A subset of 35 studies met strict quality criteria. Although high-quality studies of fine particulate matter with aerodynamic diameter ≤ 2.5 μ m (PM 2.5 ) and cognitive decline generally supported an adverse association, other findings related to PM 2.5 and findings related to particulate matter with aerodynamic diameter ≤ 10 μ m (PM 10 , NO 2 , and NO x ) were inconclusive, and too few papers reported findings with ozone to comment on the likely direction of association. Notably, only a few findings on dementia were included for consideration on the basis of quality criteria.

DISCUSSION

Strong conclusions remain elusive, although the weight of the evidence suggests an adverse association between PM 2.5 and cognitive decline. However, we note a continued need to confront methodological challenges in this line of research. https://doi.org/10.1289/EHP8716.

Discharge Communication of Dementia-Related Neuropsychiatric Symptoms and Care Management Strategies During Hospital to Skilled Nursing Facility Transitions

Provided the complexity of managing dementia-related neuropsychiatric symptoms (NPS), accurate communication about these symptoms at hospital discharge is critical to facilitating safe and effective transitions, particularly transitions from hospitals to skilled nursing facilities (SNF), which are often poorly managed. Skilled nursing facilities providers have cited undercommunication regarding NPS as a major challenge that contributes to poor outcomes including rehospitalization. This multisite retrospective cohort study identified omission rates for NPS and associated management strategies in discharge communication as compared to medical record documentation in the 72 hours preceding discharge among hospitalized patients with dementia. High rates of omission were found across NPS and management strategies: anxiety (94%), agitation/aggression (77%), hallucinations (85%), 1:1 supervision (90%), high fall risk (89%), use of restraints (91%). Omission rate for new or modified antipsychotic medication was 12.9%. Findings underscore the need for additional research on cross-setting communication regarding care needs of patients with dementia-who often cannot communicate these needs on their own-in facilitating high-quality transitions.

Evaluating racial disparities in healthcare system utilization and caregiver burden among older adults with dementia

OBJECTIVE

To evaluate racial differences in healthcare utilization and caregiver burden in a culturally diverse population of older adults with dementia.

METHOD

One hundred and thirty-three dyads (person with dementia, PWD and caregiver, CG), with at least one emergency department (ED) visit or hospitalization 12 months prior, were enrolled. Independent sample t-tests and chi-squared analyses were performed to compare racial groups on healthcare utilization and CG burden. Mann-Whitney U test was used for item-level analyses, principal component analysis was used to examine relationships among outcomes, and regressions were used to identify the relationship between race and potential covariates.

RESULTS

PWD sample mean age was 79 years, predominantly female, and with high school education. Racial distribution was 65% White and 35% Black. CG sample mean age was 64 years, predominantly female, with more than 12 years of education. No differences were found for age or dementia severity across racial groups. Black PWD experienced more ED and ambulance utilization when compared to White counterparts. Non-emergency hospitalization rates were higher for White PWD. No significant differences were found by race for CG burden total score; however, item-level analysis suggested more anger, reduced social life, uncertainty, and inadequacy in White CGs. Regressions demonstrated a positive relationship between Black race and adult-child CGs with increased ED visits, while dyad educational attainment was associated with hospitalizations independent of race.

CONCLUSIONS

Healthcare utilization disparities extend to older adults with dementia diagnoses. Our findings suggest that culturally tailored interventions may be appropriate. Future research is encouraged to explore the effect of other covariates.

Prevalence, determinants and practical implications of inappropriate hospitalizations in older subjects: A prospective observational study

In a context of high demand for hospital services among older people, we aimed to assess the rate and determinants of inappropriate hospitalizations of older patients, and to what extent they were associated with inappropriate hospital stay. This prospective observational multicentre study evaluated a random sample of consecutive patients aged ≥ 70 years accessing the Emergency Department (ED) of two Italian tertiary hospitals. A standardized comprehensive geriatric assessment was carried out in each patient, including the Blaylock Risk Assessment Screen Scale (BRASS) for identification of patients at risk of difficult discharge. Inappropriate hospitalization was defined by the ED physician when patients did not necessitate hospital-provided procedures but was due to social reasons or lack of an alternative care-setting. Among 1877 patients (median age 80.7 years, 50.1% male), with a high prevalence of functional dependence and social isolation (around 30% and 25%, respectively), 767 (40.9%) were hospitalized. Incidence of inappropriate hospitalization was 14.6% (95% CI 12.1%-17.1%) and was associated with moderate-high risk of difficult discharge at BRASS (OR = 1.98, 95% CI 1.16-3.39, p = 0.013) and the presence of dementia with behavioural disorders (OR = 1.79, 95% CI 1.10-2.91, p = 0.020). Compared with patients appropriately admitted, inappropriate hospitalizations had shorter length of hospital stay but accounted for 1059/9154 days of stay (11.6%). Inappropriate hospitalizations occurred in less than 15% of cases, mainly accounted for by patients no longer manageable at home, but contributed to the greatest proportion of inappropriate hospital stay. These findings highlight the need of implementing appropriate home-care services and ensuring rapid access to suitable care-facilities for community-dwelling frail older patients.

Ethical Considerations in Dementia Diagnosis and Care: AAN Position Statement

Alzheimer disease and other dementias present unique practical challenges for patients, their families, clinicians, and health systems. These challenges reflect not only the growing public health effect of dementia in an aging global population, but also more specific ethical complexities including early loss of patients' capacity to make decisions regarding their own care, the stigma often associated with a dementia diagnosis, the difficulty of balancing concern for patients' welfare with respect for patients' remaining independence, and the effect on the physical, emotional, and financial well-being of family caregivers. Caring for patients with dementia requires respecting patient autonomy while acknowledging progressively diminishing decisional capacity and continuing to provide care in accordance with other core ethical principles (beneficence, justice, and nonmaleficence). Whereas these ethical principles remain unchanged, neurologists must reconsider how to apply them given changes across multiple domains including our understanding of disease, clinical and legal tools for addressing manifestations of illness, our expanding awareness of the crucial role of family caregivers in providing care and maintaining patient quality of life, and societal conceptions of dementia and individuals' personal expectations for aging. This revision to the American Academy of Neurology's 1996 position statement summarizes ethical considerations that often arise in caring for patients with dementia; although it addresses how such considerations influence patient management, it is not a clinical practice guideline.
