Data of a sub-analysis of the DEMDATA study: characteristics of Austrian and Czech nursing homes residents.

OBJECTIVES: The aim of this data paper is to provide the data set of a sub-analysis of the DEMDATA study data. In the DEMDATA study, epidemiological data on the prevalence and severity of dementia, as well as functioning, behavioral problems and other health related factors in residents living in Austrian and Czech nursing homes were collected. The DEMDATA project further provides information on relatives' perception of the life Quality of residents, care team burden as well as environmental factors. Participating nursing homes were randomly drawn and stratified. Inclusion criteria for participation were that the resident was living permanently in the institution and that he/she and/or a legal representative (where relevant) had signed an informed consent. DATA DESCRIPTION: This paper provides data of cognitive, functional and behavioral assessments as well as other health related information of 1085 residents living in Austrian and Czech nursing homes. For each resident, several measurements on his or her cognitive, functional, and behavioral status are available. Also further health-related factors such as quality of life, pain, numbers of falls and hospital stays are provided.

Cognitive status and use of analgesics and anxiolytics in residents of nursing homes in the Czech Republic.

BACKGROUND: The treatment of pain and treatment of anxiety are two of the most complex issues in nursing homes worldwide, mainly because of the large numbers of people with cognitive impairment who reside in this environment. AIM: The aim of this study was to investigate the administration of analgesics and anxiolytics to people living in nursing homes, taking into account cognitive status. METHODS: For this cross-sectional study, we used data from 404 residents who lived in nine randomly selected nursing homes in the Czech Republic and participated in the Czech-Austrian Long-Term Care Research Project called DEMDATA. Information about medication administration was obtained from medical records. Cognitive impairment was evaluated by the Mini-Mental State Examination, and pain was measured by the Pain Assessment in Advanced Dementia. To measure anxiety, we used the Behavioral Pathology in Alzheimer's Disease Rating Scale in residents with severe-to-moderate dementia and also the standardized questionnaire EuroQol in other residents. RESULTS: In all, 68% (95% CI 62-74) of residents with pain did not receive any analgesic medication and 31% (95% CI 25-38) of residents were administered some analgesics and continued to report pain. The lowest reported occurrence of pain, as well as the lowest prevalence of analgesic administration, was in residents with moderate-to-severe dementia. We found that an alarming percentage of residents in the nursing homes were not treated sufficiently. CONCLUSION: This study indicates that treatment effects should be better monitored.

Cross-sectional study of prevalence of dementia, behavioural symptoms, mobility, pain and other health parameters in nursing homes in Austria and the Czech Republic: results from the DEMDATA project.

BACKGROUND: This paper provides a first comparative exploratory analysis of our findings from DEMDATA, a collaborative project between Austria and the Czech Republic. Analysed here are data from the residents and the environment assessment protocol. METHODS: In a cross sectional study design, residents from randomly drawn and stratified nursing homes were investigated using a common study protocol. RESULTS: From a total resident pool of 1666 persons, 1085 (571 in Austria, 514 in the Czech Republic) persons signed a consent form and participated in the data collection. More than 70% of residents assessed were female and the population was on average 85 years old. A discrepancy between the presence of a medical diagnosis in the charts of the residents and the results of cognitive testing was found. In Austria, 85.2%, in the Czech Republic 53.0% of residents had cognitive impairment. In Austria 80.0%, and in the Czech Republic 56.7% had behavioural problems. With respect to pain, 44.8% in Austria, and 51.5% in the Czech Republic had mild to severe pain. 78.4% of Austrian and 74.5% of the residents had problems with mobility and both populations were in danger of malnutrition. CONCLUSIONS: Most of the prevalence rates are comparable with previous studies also using direct resident assessment. Variations in prevalence rates seem to result mainly from the assessment technique (direct cognitive testing vs. medical chart review). The high prevalence rates for dementia, behavioural symptoms, pain and malnutrition indicate an immediate call for attention to further research and practice development.

Dementia service centres in Austria: A comprehensive support and early detection model for persons with dementia and their caregivers - theoretical foundations and model description.

Despite the highly developed social services in Austria, the County of Upper Austria, one of the nine counties of Austria had only very limited specialized services for persons with dementia and their caregivers in 2001. Support groups existed in which the desire for more specialized services was voiced. In response to this situation, funding was received to develop a new structure for early disease detection and long term support for both the person with dementia and their caregivers. This article describes the development of the model of the Dementia Service Centres (DSCs) and the successes and difficulties encountered in the process of implementing the model in six different rural regions of Upper Austria. The DSC was described in the First Austrian Dementia Report as one of the potential service models for the future.

Evidence and mechanisms of retrogenesis in Alzheimer's and other dementias: management and treatment import.

Retrogenesis is the process by which degenerative mechanisms reverse the order of acquisition in normal development. Alzheimer's disease (AD) and related conditions in the senium have long been noted to resemble "a return to childhood" Previously, we noted that the functional stages of AD precisely and remarkably recapitulated the acquisition of the same functional landmarks in normal human development. Subsequent work indicated that this developmental recapitulation also applied to the cognitive and related symptoms in AD. Remarkably, further investigations revealed that the same neurologic "infantile" reflexes, which mark the emergence from infancy in normal development, are equally robust indicators of corresponding stages in AD. Neuropathologic and biomolecular mechanisms for these retrogenic processes are now evident. For example, the pattern of myelin loss in AD appears to mirror the pattern of myelin acquisition in normal development. Also, recent findings indicate that mitogenic factors become reactivated in AD, and, consequently, the most actively "growing" brain regions are the most vulnerable. Because of this robust retrogenic process, the stages of AD can be translated into corresponding developmental ages (DAs). These DAs can account for the overall management and care needs of AD patients. A science of AD management can be formulated on the basis of the DA of the Alzheimer's patient, taking into consideration differences of AD from normal development as well as homologies.
