[Administrative Prevalence and Health Care Situation of Dementia Patients in Acute Care Hospitals: An Epidemiological Health Care Study Based on Claims Data of Insured Persons in Saxony]. / Administrative Prävalenz und Versorgungssituation der Demenz im Krankenhaus ­ Eine versorgungsepidemiologische Studie basierend auf GKV-Daten sächsischer Versicherter.

OBJECTIVE: The increasing number of people with dementia will challenge the health care system, especially acute care. Using health insurance claims data, the study objective was to examine the regional patterns of the administrative prevalence of dementia, the prevalence of dementia in hospitals and the care situation in hospitals. METHODS: We used 2014 claims data from AOK PLUS, the largest statutory health insurance service in Saxony. If dementia was diagnosed either in an outpatient or inpatient setting in 3 of 4 quarters in a year, a person was categorised as a dementia case (n=61,700). The analysis of health care status included 61,239 patients with dementia and 183,477 control subjects. The control group was matched using the criteria of gender, age and region of residence. RESULTS: For those older than 65 years, the overall administrative prevalence rate of dementia was 9.3%. The estimated prevalence for those in hospitals was 16.7%. In 2014, there were 33% more admissions, 36% more hospital days and 18% higher costs per person-year among people diagnosed with dementia than the control subjects. The longer annual hospital stays and the higher costs were primarily caused by the greater number of admissions of people with dementia. Inpatient service use was, compared to people without dementia, characterized by a need for care and assistance, rather than by a need for medical therapeutic and diagnostic procedures. CONCLUSION: To improve the health care situation of people with dementia, to adapt to the challenges facing hospitals and to reduce the financial burden caused by dementia, more efforts are needed to improve the health care situation. Measures include, among others, improvements in recognition of dementia and reduction of unnecessary hospital stays.

Determinants of hospitalization and length of stay among people with dementia - An analysis of statutory health insurance claims data.

OBJECTIVE: Dementia is a crucial challenge in acute care hospitals. Using a retrospective claims data cohort, this paper explores dementia patients' acute hospitalization rates, risk factors, and length of stay. METHODS: The study used claims data from AOK PLUS, the largest statutory health insurance service (SHI) in Saxony, a federal state of Germany. The analysis included 61,239 people with dementia and 183,477 control subjects, all 65 years and older. Control subjects were age, gender, and regionally matched in a 1:3 ratio. Negative binomial hurdle regression was used to compare differences in hospitalization for the year 2014. RESULTS: People with dementia had 1.49 times higher adjusted odds of being hospitalized at least once (95% confidence interval [CI], 1.46-1.52). Among those individuals hospitalized at least once, dementia increased the number of readmissions by 18% (95% CI, 1.15-1.20). Dementia patients also had a 1.74 times higher odds for at least one emergency admission compared to individuals without dementia (95% CI, 1.70-1.78). Dementia patients' admission risk factors included having care dependency, being recently diagnosed with dementia and living outside a metropolitan region. The increased length of stay for people with dementia per year was mainly attributable to higher admission rates. CONCLUSIONS: Dementia patients are at higher risk for hospitalization, especially if they live outside the metropolitan region. Healthcare systems need to respond to the challenges resulting from the predicted demographic developments and increasing burden of dementia in the general population.

Investigation of Eligible Picture Categories for Use as Environmental Cues in Dementia-Sensitive Environments.

OBJECTIVES: Environmental cues, such as pictures, could be helpful in improving room-finding and wayfinding abilities among older patients. The aim of this study was to identify picture categories that are preferred and easily remembered by older patients and cognitively impaired patients and which therefore might be suitable for use as environmental cues in acute care settings. METHODS: Twelve pictures were presented to a sample of older patients ( n = 37). The pictures represented different categories: familiarity (familiar vs. unfamiliar), type of shot (close-up vs. wide shot), and picture content (nature vs. animal vs. urban). We tested the patients' votes of preference and abilities to identify and immediately recall pictures. Cognitively impaired patients ( n = 14) were assessed by the abbreviated mental test and the mini mental state examination and were compared with patients without cognitive impairments ( n = 23) using a repeated measures analysis of variance. RESULTS: The results showed a main effect of familiarity on positive vote and recall of pictures. The absence of interaction effects of familiarity and group indicated an overall impact of familiarity on the sample. Within cognitively impaired patients, a significant difference in recall of picture content between urban (20%) and animal (9%) was found. CONCLUSIONS: Pictures, which patients were able to relate to in terms of familiarity and the characteristics urban and nature, seem to be suitable for use as environmental cues. Besides functioning as such, we assume, based on literature, that pictures could further enhance the ambiance or serve as prompts for communication and interaction.

[Impact of dementia on length of stay and costs in acute care hospitals]. / Einfluss der Demenz auf Verweildauer und Erlöse im Akutkrankenhaus.

BACKGROUND: The treatment of patients with dementia in acute care hospitals is becoming increasingly more important. The aim of this study was to investigate and demonstrate aspects of the healthcare situation and resource consumption of dementia patients during their hospital stay in a ward for internal medicine. MATERIAL AND METHODS: Secondary data from a ward of internal medicine were analyzed on a retrospective and case-related basis. For 100 patients a diagnosis of dementia by a general practitioner before hospitalization was identified. The control group was selected by age and sex from the other patients in the ward (n = 100). The costs were calculated on the basis of the German diagnosis-related groups (G-DRG) flat rate case classification. The relationship between dementia, deviation from the average length of stay and costs was investigated under the control of comorbidities using multivariate regression analysis. RESULTS: Patients with dementia had poorer health at admission with respect to functionality and orientation and a higher risk of falls and pressure ulcers. During hospitalization patients with dementia fell more frequently than patients without dementia (12 % versus 3 %, p = 0.029). Regarding the average length of stay, according to the G­DRG catalogue patients with dementia stayed 1.4 days longer in hospital than patients without dementia and caused excess costs of 19 %. CONCLUSION: Patients with dementia are a highly vulnerable patient group with a higher consumption of resources than patients without dementia. The results demonstrate the care-related and economic consequences, which the increasing number of patients with dementia could have in the future.

Environmental Cues in Double-Occupancy Rooms to Support Patients With Dementia.

OBJECTIVE: The purpose of this study was to evaluate the effectiveness of different environmental cues in double-occupancy rooms of an acute care hospital to support patients' abilities to identify their bed and wardrobe. METHODS: The quasi-experiment was conducted on a geriatric ward of an acute care hospital. Patients with dementia were included (n = 42). To test the effectiveness of environmental cues, two rooms were enhanced with the environmental cue "color," two rooms with the cue "number," and two rooms with the cue "patient's name". Four rooms were not redesigned and were used as control rooms. For analysis, we pooled the intervention groups color and number (n = 14) and compared it with the control group (n = 22). RESULTS: The environmental cues color and number were significantly effective to improve the identification of the wardrobe from the third to the fifth day after admission. However, for the 10th-12th day after admission, we found no difference in results. Furthermore, results indicate improvements in the ability to identify the bed by using the environmental cues color and number. CONCLUSIONS: As this study indicated, the environmental cues color and number are helpful for these patients to identify their bed and wardrobe. However, these cues were most effective from the third to the fifth day after admission. To sustain their effectiveness on patients' identification abilities during their hospital stay, we discuss, whether verbal prompting and an ongoing mentioning of such cues, embedded in the daily work of nurses, could be beneficial.

Impact of the design of the built environment on people with dementia: an evidence-based review.

OBJECTIVE: In this review the impact of the design of the built environment on people with dementia in long-term care settings is systematically analyzed and summarized. Architects and designers will be provided with credible evidence on which they can confidently base their design decisions. Researchers will be able to determine which environmental aspects have been well investigated and where there are gaps in the current state of the research. BACKGROUND: A great number of studies have established a relationship between the design of the physical environment of long-term care settings and outcomes of people with dementia. However, the methods employed are heterogeneous and the results are often conflicting. Consequently, the process of integrating the best evidence available into architectural designs may be hindered. METHODS: A systematic literature search was conducted reviewing studies that meet certain inclusion criteria. Using an evidence-based approach, the methodical quality of the studies was rated. RESULTS: One hundred sixty-nine studies were found. They were thematically summarized into four main categories: basic design decisions, environmental attributes, ambience, and environmental information. The effectiveness of the interventions on the behavior, cognition, function, well being, social abilities, orientation, and care outcomes on people with dementia was illustrated by matrices. CONCLUSIONS: Results of this review indicate that, with the exception of cognition, specific design interventions are beneficial to the outcomes of people with dementia. Overall, the field of environmental design for people with dementia is well researched in many aspects and only few gaps in knowledge were identified.

Effectiveness of preventive home visits in reducing the risk of falls in old age: a randomized controlled trial.

BACKGROUND: Falls in older people are a major public health issue, but the underlying causes are complex. We sought to evaluate the effectiveness of preventive home visits as a multifactorial, individualized strategy to reduce falls in community-dwelling older people. METHODS: Data were derived from a prospective randomized controlled trial with follow-up examination after 18 months. Two hundred and thirty participants (≥80 years of age) with functional impairment were randomized to intervention and control groups. The intervention group received up to three preventive home visits including risk assessment, home counseling intervention, and a booster session. The control group received no preventive home visits. Structured interviews at baseline and follow-up provided information concerning falls in both study groups. Random-effects Poisson regression evaluated the effect of preventive home visits on the number of falls controlling for covariates. RESULTS: Random-effects Poisson regression showed a significant increase in the number of falls between baseline and follow-up in the control group (incidence rate ratio 1.96) and a significant decrease in the intervention group (incidence rate ratio 0.63) controlling for age, sex, family status, level of care, and impairment in activities of daily living. CONCLUSION: Our results indicate that a preventive home visiting program can be effective in reducing falls in community-dwelling older people.

Direct costs associated with depressive symptoms in late life: a 4.5-year prospective study.

BACKGROUND: Depression in old age is common. Only few studies examined the association of depressive symptoms and direct costs in the elderly in a cross-sectional way. This study aims to investigate prospectively health service use and direct costs over a course of 4.5 years considering also different courses of depressive symptomatology. METHODS: 305 primary care patients aged 75+ were assessed face-to-face regarding depressive symptoms (Geriatric Depression Scale), and service use and costs at baseline and 4.5 years later. Resource utilization was monetarily valued using 2004/2005 prices. The association of baseline factors and direct costs after 4.5 years was analyzed by multivariate linear regression. RESULTS: Mean annual direct costs of depressed individuals at baseline and follow-up were almost one-third higher than of non-depressed, and highest for individuals with chronic depressive symptoms. Most relevant cost drivers were costs for inpatient care, pharmaceuticals, and home care. Costs for home care increased at most in individuals with chronic depressive symptoms. Baseline variables that were associated with direct costs after 4.5 years were number of medications as a measure of comorbidity, age, gender, and depressive symptoms. CONCLUSIONS: Presence and persistence of depressive symptoms in old age seems to be associated with future direct costs even after adjustment for comorbidity. The findings deign a look to the potential economic consequences of depressive symptoms in the elderly for the healthcare system in the future.

Health service utilization and costs of depressive symptoms in late life - a systematic review.

OBJECTIVE: The objective of the study is to systematically analyze and summarize research literature regarding health service use and costs of depressive symptoms in late life. DESIGN: Relevant articles were identified by systematically searching the databases MEDLINE, Web of Science, PSYNDEXplus, PsycINFO, and Cochrane Library. Keywords were 'depression' or 'depressive*', and 'cost' or 'economic burden' or 'utilization' or 'use' and 'old age' or 'elderly'. Studies based on representative samples of elderly individuals aged 55 years and older were included. RESULTS: 55 studies were found, 34 studies determined health service utilization, 10 studies reported costs, and 11 studies reported both. Studies of health service utilization and costs showed homogeneously that depressive elderly individuals have an increased service use compared to non-depressive, and a one-third increase of outpatient, inpatient, and total healthcare costs of depressive individuals. The majority of studies reported antidepressant (AD) use between 20 and 45% by depressive individuals. Mean annual costs for AD ranged from 108 to 305 US$ PPP (purchasing power parities). Increased service use and costs are only to a small proportion related to depression treatment. CONCLUSIONS: Depressive symptoms in late life lead to a high economic burden for nations which is not explained by costs for depressive symptom treatment. Strategies for improvement of diagnostic validity and treatment success of depressive symptoms in late life may have an effect on economic burden for societies.

[Psychiatry of the life span?--relevance of age in psychiatric research]. / Psychiatrie der Lebensspanne?--Der Altersbezug in der psychiatrischen Forschung.

OBJECTIVE: The aim of this study was to determine to what extent studies published in two German journals took the age of their sample into consideration. METHODS: All publications of the two journals were viewed. Only empirical research papers were included. It was then assessed whether they included information on age of the sample and, if that was the case, the studies were further categorized as only giving descriptive sample information, reporting age-specific results of dependent variables or using age as a predictor in regression analyses. Furthermore, the age range covered was assessed. RESULTS: 88 % of all studies included information on age. Of those, about half only provided descriptive information on the age of the study sample, while more than one third used the age variable as a predictor in multivariate models. Few studies reported age-specific outcomes. Main focus of research was on adult populations aged 18 to 65. Only few studies concentrated on children and adolescents. CONCLUSIONS: In light of demographic change and age specificity of psychological disorders, it will be necessary to further differentiate and report age-specific results of psychiatric research. A change in what is considered normative aging and developmental tasks for certain age groups calls for further research in those age groups.
