Clinical characteristics of patients with dementia in a local emergency clinic in Japan

Emergency Care for Persons Living with Dementia

Assessments are available which can help to identify emergency department (ED) patients who may have dementia. Persons living with dementia (PLWD) have unique emergency care needs such as difficulties with activities of daily living and behavioral and psychological symptoms of dementia. Multiple emergency care practices have shown improved outcomes for PLWD. Communication between clinicians and PLWD requires additional attention and should include care partners and other clinicians when possible. Transitions of care from the ED for PLWD are often problematic with poor outcomes. Interventions like community paramedicine follow up may improve the transition from the ED to the community.

Preventable adverse events and related outcomes among people with dementia in hospital settings: scoping review

OBJECTIVES

To explore the hospital-related adverse events endured by people with dementia and assess their association with negative outcomes related to hospital care.

METHOD

A scoping review was undertaken in October 2023. Primary studies published in peer-reviewed journals in English, Spanish, or Portuguese were included. The databases PubMed, Web of Science, CINAHL, and Scopus were searched.

RESULTS

Of the 1976 retrieved studies, 16 were included. Adverse events were more frequent among people with dementia compared to people without dementia. In studies with non-surgical and surgical patients, the most frequently reported were falls, delirium, and infections, while in studies exclusively conducted with surgical patients, these were postoperative delirium, infections, and other complications. The link between adverse events and negative outcomes was explored in only three studies and indicated that those who experienced adverse events had longer hospital stays, higher risk of mortality, and higher readmission rates within 90 days.

CONCLUSION

Although we were unable to establish a direct link between adverse events and hospital outcomes due to the exploratory nature of this review, the findings suggest that mitigating such events could help improve outcomes among hospitalized people with dementia. Hospital safety measures appear to be insufficient to protect this group.

Continuous Glucose Monitoring in Comorbid Dementia and Diabetes: The Evidence So Far

BACKGROUND

Type 2 diabetes mellitus (T2DM) and dementia are two of the leading chronic diseases in aging and are known to influence each other's disease progression. There is well-established evidence that T2DM increases the risk for cognitive decline and dementia. At the same time, people with cognitive changes or dementia can find it difficult to manage their diabetes, resulting in hyper- or hypoglycemic events which can exacerbate the dementia disease progression further. Monitoring of glucose variability is, therefore, of critical importance during aging and when people with T2DM develop dementia. The advent of continuous glucose monitoring (CGM) has allowed the monitoring of glucose variability in T2DM more closely. The CGM seems to be highly feasible and acceptable to use in older people with T2DM and has been shown to significantly reduce their hypoglycemic events, often resulting in falls. Less is known as to whether CGM can have a similar beneficial effect on people with T2DM who have cognitive impairment or dementia in community or hospital settings.

AIMS

The current perspective will explore how CGM has made an impact on T2DM management in older people and those with comorbid cognitive impairment or dementia. We will further explore opportunities and challenges of using CGM in comorbid T2DM and dementia in community and hospital settings.

Clinical characteristics of older patients with suspected or diagnosed dementia during hospitalization

AIM

In Japan, an additional system for patients with suspected or diagnosed dementia during hospitalization for physical illness began in 2016. We examined the clinical characteristics of older patients with suspected or diagnosed dementia during hospitalization.

METHODS

The study participants consisted of 569 patients. Current age, sex, comorbidities, causative disease for admission, body mass index (BMI), blood tests, environment before admission, prescription history before admission and rate of delirium were examined. Simple regression analysis for high-frequency diseases was carried out with the respective risk factors as independent variables. Multiple regression analysis was then carried out.

RESULTS

Infection had the highest frequency in the causative diseases for admission. A total of 48% of patients had delirium during hospitalization. The delirium group had the highest frequency of being at home. In the infection group, BMI and serum albumin were lower in the non-infection group (BMI 19.0 ± 3.7 vs 20.4 ± 4.1; P < 0.001, albumin 2.1 ± 0.7 vs 3.3 ± 0.6 g/dL; P < 0.001 respectively). White blood cell count and C-reactive protein were higher than in the non-infection group, respectively (white blood cell count 11181.4 ± 6533.3 vs 8765.8 ± 111 424.3/μL; P = 0.007, C-reactive protein 8.6 ± 8.6 vs 3.0 ± 5.2 mg/dL; P < 0.001 respectively). Using independent factors associated with infection, multiple regression analysis was performed. BMI (P = 0.013), serum albumin (P < 0.001) and nursing home care before admission (P < 0.001) had significant correlations.

CONCLUSIONS

Assessment of delirium and the environment before admission of older patients with suspected or diagnosed dementia when hospitalized are necessary. Furthermore, evaluation of nutrition might also contribute to reducing deterioration due to physical illness. Geriatr Gerontol Int 2024; 24: 641-645.

Optimizing the Care of Persons Living with Dementia in the Emergency Department

Emergency department (ED) care for persons living with dementia (PLWD) involves the identification of dementia or cognitive impairment, ED care which is sensitive to the specific needs of PLWD, effective communication with PLWD, their care partners, and outpatient clinicians who the patient and care-partner know and trust, and care-transitions from the emergency department to other health care settings. The recommendations in this article made based on wide-ranging heterogeneous studies of various interventions which have been studied primarily in single-site studies. Future research should work to incorporate promising findings from interventions such as hospital at home, or ED to home Care Transitions Intervention.

History of Falls and Bedriddenness Ranks are Useful Predictive Factors for in-Hospital Falls: A Single-Center Retrospective Observational Study Using the Saga Fall Risk Model

INTRODUCTION

In our former study, we had validated the previously developed predictive model for in-hospital falls (Saga fall risk model) using eight simple factors (age, sex, emergency admission, department of admission, use of hypnotic medications, history of falls, independence of eating, and Bedriddenness ranks [BRs]), proving its high reliability. We found that only admission to the neurosurgery department, history of falls, and BRs had significant relationships with falls. In the present study, we aimed to clarify whether each of these three items had a significant relationship with falls in a different group of patients.

METHODS

This was a single-center based, retrospective study in an acute care hospital in a rural city of Japan. We enrolled all inpatients aged 20 years or older admitted from April 2015 to March 2018. We randomly selected patients to fulfill the required sample size. We performed multivariable logistic regression analysis using forced entry on the association between falls and each of the eight items in the Saga fall risk model 2.

RESULTS

A total of 2932 patients were randomly selected, of whom 95 (3.2%) fell. The median age was 79 years, and 49.9% were men. Multivariable analysis showed that female sex (odds ratio [OR] 0.6, 95% confidence interval [CI] 0.39-0.93, p = 0.022), having a history of falls (OR 1.9, 95% CI 1.16-2.99, p = 0.010), requiring help with eating (OR 1.9, 95% CI 1.12-3.35, p = 0.019), BR of A (OR 6.6, 95% CI 2.82-15.30, p < 0.001), BR of B (OR 7.5, 95% CI 2.95-19.06, p < 0.001), and BR of C (OR 4.1, 95% CI 1.53-11.04, p = 0.005) were significantly associated with falls.

CONCLUSION

History of falls and BRs were independently associated with in-hospital falls.

Optimal Emergency Department Care Practices for Persons Living With Dementia: A Scoping Review

OBJECTIVES

To summarize research on optimal emergency department (ED) care practices for persons living with dementia (PLWDs) and develop research priorities.

DESIGN

Systematic scoping review.

SETTINGS AND PARTICIPANTS

PLWDs in the ED.

METHODS

The following Patient-Intervention-Comparison-Outcome (PICO) questions were developed: PICO 1, What components of emergency department care improve patient-centered outcomes for persons with dementia? PICO 2, How do emergency care needs for persons with dementia differ from other patients in the emergency department? A scoping review was conducted following PRISMA-ScR guidelines and presented to the Geriatric Emergency care Applied Research 2.0 Advancing Dementia Care network to inform research priorities.

RESULTS

From the 6348 publications identified, 23 were abstracted for PICO 1 and 26 were abstracted for PICO 2. Emergency care considerations for PLWDs included functional dependence, behavioral and psychological symptoms of dementia, and identification of and management of pain. Concerns regarding ED care processes, the ED environment, and meeting a PWLD's basic needs were described. A comprehensive geriatric assessment and dedicated ED unit, a home hospital program, and a low-stimulation bed shade and contact-free monitor all showed improvement in patient-centered or health care use outcomes. However, all were single-site studies evaluating different outcomes. These results informed the following research priorities: (1) training and dementia care competencies; (2) patient-centric and care partner-centric evaluation interventions; (3) the impact of community- and identity-based factors on ED care for PLWDs; (4) economic or other implementation science measures to address viability; and (5) environmental, operational, personnel, system, or policy changes to improve ED care for PLWDs.

CONCLUSIONS AND IMPLICATIONS

A wide range of components of both ED care practices and ED care needs for PLWDs have been studied. Although many interventions show positive results, the lack of depth and reproducible results prevent specific recommendations on best practices in ED care for PLWDs.

Weight loss in Alzheimer's disease, vascular dementia and dementia with Lewy bodies: Impact on mortality and hospitalization by dementia subtype

OBJECTIVES

Loss of weight is associated with cognitive decline as well as several adverse outcomes in dementia. The aim of this study was to assess whether weight loss is associated with mortality and hospitalization in dementia subtypes.

METHODS

A cohort of 11,607 patients with dementia in Alzheimer's disease (AD), vascular dementia (VD), or dementia with Lewy bodies (DLB) was assembled from a large dementia care health records database in Southeast London. A natural language processing algorithm was developed to established whether loss of weight was recorded around the time of dementia diagnosis. Cox proportional hazard models were applied to examine the associations of reported weight loss with mortality and emergency hospitalization.

RESULTS

Weight loss around the time of dementia was recorded in 25.5% of the whole sample and was most common in patients with DLB. A weight loss-related increased risk for mortality was detected after adjustment for confounders (Hazard ratio (HR):1.07; 95% confidence interval (CI):1.02-1.15) and in patients with AD (HR: 1.11; 95% CI: 1.04-1.20), but not in DLB and VD. Weight loss was associated with a significantly increased emergency hospitalization risk (HR: 1.14; 95% CI: 1.08-1.20) and in all three subtypes.

CONCLUSIONS

While there were associations with increased hospitalization risk for all three subtype diagnoses, weight loss was only associated with increased mortality in AD. Weight loss should be considered as an accompanying symptom in dementia and interventions should be considered to ameliorate risk of adverse outcomes.

Health and long-term care of the elderly with dementia in rural Thailand: a cross-sectional survey through their caregivers

OBJECTIVE

To describe the circumstances of the elderly with dementia and their caregivers' characteristics in order to examine factors related to activities of daily living (ADL) and household income to propose a long-term care policy for rural areas of Thailand.

SETTING

A cross-sectional study at the household level in three rural regions of Thailand where there were initiatives relating to community care for people with dementia.

PARTICIPANTS

Caregivers of 140 people with dementia were recruited for the study.

PRIMARY AND SECONDARY OUTCOME MEASURES

Socioeconomic characteristics including data from assessment of ADL and instrumental ADL and the Thai version of Resource Utilisation in Dementia were collected. Descriptive statistics were used to explain the characteristics of the elderly with dementia and the caregivers while inferential statistics were used to examine the associations between different factors of elderly patients with dementia with their dependency level and household socioeconomic status.

RESULTS

Eighty-six per cent of the dementia caregivers were household informal caregivers as half of them also had to work outside the home. Half of the primary caregivers had no support and no minor caregivers. The elderly with dementia with high dependency levels were found to have a significant association with age, dementia severity, chance of hospitalisation and number of hospitalisations. Though most of these rural samples had low household incomes, the patients in the lower-income households had significantly lower dementia severity, but, with the health benefit coverage had significantly higher chances of hospitalisation.

CONCLUSION

As the informal caregivers are the principal human resources for dementia care and services in rural area, policymakers should consider informal care for the Thai elderly with dementia and promote it as the dominant pattern of dementia care in Thailand.
