Association between physical activity and costs in very mild to moderately frail community-dwelling older adults: a cross-sectional study.

BACKGROUND: Physical activity (PA) plays a vital role in maintaining the functional ability that enables well-being in older age (healthy aging), potentially also saving costs for the healthcare system and society. The aim of this study was to examine the association between PA and healthcare and societal costs in a sample of very mild to moderately frail older adults. METHODS: This cross-sectional study is a secondary analysis using baseline data from the PromeTheus randomized-controlled trial, which included 385 very mild to moderately frail community-dwelling older adults (70 + years) from Germany. Participants self-reported their health-related resource use in the previous 6 months (FIMA questionnaire), which was monetarily valued using standardized unit costs. PA was also self-reported using the German Physical Activity Questionnaire for middle-aged and older adults (German-PAQ-50+) and categorized as 'insufficient'/'sufficient' or 'insufficient'/'moderate'/'high' in accordance with the World Health Organization guidelines for PA. Mean and median healthcare costs (including outpatient, inpatient, rehabilitation, formal care, and medication costs) and societal costs (healthcare costs plus informal care costs) for different PA groups were estimated using generalized linear models and quantile regression, with sociodemographic variables and physical capacity (Short Physical Performance Battery) as covariates. RESULTS: Of the sample, 24% were classified as insufficiently, 23% as moderately, and 54% as highly active. Sufficient PA, especially high PA, was associated with lower costs in the 6 months prior to data collection compared to insufficient PA (-€6,237, 95% CI [-10,656; -1,817] and -€8,333, 95% CI [-12,183; -4,483], respectively). The cost difference between PA intensity groups was largely driven by differences in informal care costs and decreased substantially when physical capacity was accounted for in the analyses; e.g., the mean difference in societal costs between sufficient and insufficient PA decreased from -€7,615 (95% CI [-11,404; -3,825]) to -€4,532 (95% CI [-7,930; -1,133]). CONCLUSION: Promoting PA throughout the lifespan as a means of promoting healthy aging and reducing dependency in old age could potentially provide economic benefits and help to mitigate the economic consequences of an aging population with increasing health and long-term care needs. Future longitudinal studies should attempt to disentangle the mediating and confounding role of physical capacity and health status in the association between PA and costs.

Prevention at home in older persons with (pre-)frailty: analysis of participants' recruitment and characteristics of the randomized controlled PromeTheus trial.

BACKGROUND: The "PromeTheus" trial is evaluating a home-based, multifactorial, interdisciplinary prevention program for community-dwelling (pre-)frail older adults. These individuals often suffer from reduced participation, which can complicate the recruitment and enrollment in a clinical trial. AIMS: The aim of this study was to evaluate different recruitment strategies and differences in participant characteristics in relation to these strategies. METHODS: This cross-sectional study used baseline data from the randomized-controlled PromeTheus trial, in which community-dwelling (pre-)frail older persons (Clinical Frailty Scale [CFS] 4-6 pt., ≥ 70 years) were recruited via general practitioners ("GP recruitment") or flyers, newspaper articles, and personalized letters ("direct recruitment"). Differences in the sociodemographic, clinical, physical, functional, mobility-related, psychological and social characteristics were analyzed in relation to the recruitment strategy. RESULTS: A total of 385 participants (mean age = 81.2, SD 5.9 years; women: n = 283, 73.5%) were enrolled, of which 60 (16%) were recruited by GPs and 325 (84%) through direct recruitment. Participants recruited via GPs had significantly higher subjective frailty levels (CFS), were more often physically frail (Fried Frailty Phenotype), and showed lower physical capacity (Short Physical Performance Battery), participation (disability component of the short version of the Late-Life Function and Disability Instrument), and life-space mobility (Life-Space Assessment) compared to those recruited via the direct approach (p = 0.002-0.026). Costs per randomized participant were 94€ for the GP recruitment strategy and €213 for the direct recruitment strategy. CONCLUSION: Different strategies may be required to successfully recruit (pre-)frail home-living older adults into preventive programs. Direct recruitment strategies, in which potential participants are directly informed about the prevention program, seem to be more promising than GP recruitment but may result in enrolment of persons with less functional impairment and higher recruitment costs.

A multifactorial interdisciplinary intervention to prevent functional and mobility decline for more participation in (pre-)frail community-dwelling older adults (PromeTheus): study protocol for a multicenter randomized controlled trial.

BACKGROUND: Age-related decline in physical capacity can lead to frailty, associated with an increased vulnerability to adverse health outcomes and greater healthcare utilization. In an aging population, effective strategies to prevent physical decline and frailty, and preserve independence are needed. Prevention programs for vulnerable community-dwelling older adults are, however, often not yet established and implemented in routine practice. Research on the feasibility, implementation, and (cost-)effectiveness of multifactorial, interdisciplinary intervention programs that take advantage of available services of healthcare providers is also limited. The main aim of this study is to evaluate the effectiveness of such an intervention program (PromeTheus) to prevent functional and mobility decline for more participation in community-dwelling (pre-)frail older adults. METHODS: The study is designed as a three-center, randomized controlled trial with a 12-month intervention period. Four hundred community-dwelling (pre-)frail (Clinical Frailty Scale score 4-6) older adults (≥70 years) will be randomized in a 1:1 ratio to the intervention group (IG) or the control group (CG). The IG will receive the PromeTheus program consisting of obligatory home-based physical exercises (Weight-bearing Exercise for Better Balance) accompanied by physiotherapists and facultative counseling services (person-environment-fit, coping with everyday life, nutrition, group-based activities) delivered via existing healthcare structures (e.g., social workers, nutritionists). The CG will receive usual care and a one-time counseling session on recommendations for physical activity and nutrition. Primary outcomes assessed at months 6 and 12 are the function component of the Late-Life Function and Disability Instrument and the University of Alabama at Birmingham Life-Space Assessment. Secondary outcomes are disability, physical capacity and activity, frailty, nutritional status, falls, fear of falling, health status, and psychosocial components. Process and economic evaluations are also conducted. Primary statistical analyses will be based on the intention-to-treat principle. DISCUSSION: Compared to usual care, the PromeTheus program is expected to result in higher function and mobility, greater independence and lower need for care, and more participation. As the PromeTheus program draws on existing German healthcare structures, its large-scale translation and delivery will be feasible, if evidence of (cost-)effectiveness and successful implementation can be demonstrated.

Psychometric properties of the German version of the Fear of Falling Questionnaire-revised (FFQ-R) in a sample of older adults after hip or pelvic fracture.

BACKGROUND: Identifying patients with maladaptive fear of falling (FOF) is important in the rehabilitation phase after serious fall. The 6-item Fear of Falling Questionnaire-revised (FFQ-R) was seen as promising measurement instrument as it evaluates FOF in a broader way than the one-item-question and independent of physical activities. AIM: The purpose of the analysis was to evaluate the psychometric properties of the translated German FFQ-R. METHODS: Back-translation method was applied. Confirmatory factor analysis (CFA) with diagonally weighted least square estimation was used to verify the two-factor structure. Data were collected during inpatient rehabilitation from hip and pelvic fracture patients [age 84.3 ± 6.2, Mini-Mental State Examination (MMSE) scores > 23] participating in an RCT (N = 112) and a cross-sectional survey (N = 40). RESULTS: Internal consistency was 0.78 (Cronbach´s alpha). No floor or ceiling effects were found. Discriminatory power on item level was moderate to good (r = 0.43-0.65). CFA revealed a good model fit and confirmed the two-factor structure. The German FFQ-R was moderately correlated (r = 0.51) with the Short Falls Efficacy Scale-International (Short FES-I) used as a proxy measure for FOF. Missing rates up to 9% for specific items were because some individuals, independent of cognitive level or age, had problems to rate items with conditional statements on possible negative consequences of a fall. CONCLUSIONS: Results demonstrated moderate to good psychometric properties similar to the original English version in a comparable sample of fracture patients.

Correlates of fear of falling and falls efficacy in geriatric patients recovering from hip/pelvic fracture.

OBJECTIVE: To gain a better understanding about the nature of fear of falling, this study analyzed associations between psychological and physical aspects related to fear of falling and falls efficacy in hip/pelvic fracture patients. DESIGN: Baseline data of a randomized controlled trial. SETTING: Geriatric inpatient rehabilitation hospital. SUBJECTS: In all, 115 geriatric patients with hip/pelvic fracture (mean age: 82.5 years) reporting fear of falling within first week of inpatient rehabilitation. INTERVENTIONS: None. MAIN MEASURES: Falls efficacy (Short Falls Efficacy Scale-International; Perceived Ability to Manage Falls), fear of falling (one-item question), fall-related post-traumatic stress symptoms (six items based on Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) criteria), physical performance (Short Physical Performance Battery) and psychological inflexibility (Acceptance and Action Questionnaire-II) were assessed. RESULTS: Path analyses demonstrated that low falls efficacy (Short Falls Efficacy Scale International) was significantly related to poor physical performance (ß* = -.277, P ⩽ .001), but not to psychological inflexibility and fall-related post-traumatic stress symptoms (P ⩾ .05.). Fear of falling was directly associated with fall-related post-traumatic stress symptoms (ß*= .270, P = .007) and indirectly with psychological inflexibility (ß*= .110, P = .022). Low perceived ability to manage falls was significantly related to previous falls (ß* = -.348, P ⩽ .001), psychological inflexibility (ß* = -.216, P = .022) and female gender (ß* = -.239, P ⩽ .01). CONCLUSION: Falls efficacy and fear of falling constitute distinct constructs. Falls efficacy measured with the Short Falls Efficacy Scale International reflects the appraisal of poor physical performance. Fear of falling measured by the single-item question constitutes a fall-specific psychological construct associated with psychological inflexibility and fall-related post-traumatic stress symptoms.

Increasing Physical Activity in Persons With Dementia: A Randomized Controlled Trial.

This study investigated the effectivity and sustainability of a physical activity (PA) promotion and motor training programs and analyzed predictors for PA changes in persons with dementia. A total of 122 participants with mild-to-moderate dementia were randomized to the intervention program designed for persons with dementia (intervention group) or a motor placebo activity (control group). The primary outcome was the Physical Activity Questionnaire for the Elderly assessed at the baseline, after the 3-month intervention, and at a 3-month follow-up. The PA promotion program significantly increased PA in the intervention group compared with the control group during the training intervention phase. Both groups showed an increase in habitual PA when intervention-induced activities were excluded. PA was sustainably increased in both groups at follow-up. Low baseline PA was predictive for increased PA after the intervention and low baseline PA, high motor performance, and low comorbidity for increased PA at follow-up.

Multifactorial intervention for hip and pelvic fracture patients with mild to moderate cognitive impairment: study protocol of a dual-centre randomised controlled trial (OF-CARE).

BACKGROUND: A hip or pelvic fracture is a major fall-related injury which often causes a decline in mobility performance and physical activity. Over 40% of patients with hip fracture have cognitive impairment or dementia and poorer rehabilitation outcomes than those without cognitive impairment. In this subgroup, there is a lack of evidence on the best practices supporting recovery. The main aim of this study is to investigate the effects of a transitional care intervention after inpatient rehabilitation on physical activity and functional performance in this group of cognitively impaired patients. METHODS/DESIGN: This dual-centre, randomised controlled trial compares a multifactorial intervention with usual care as control condition. Two hundred and forty community-dwellers (≥ 65 years) with a hip or pelvic fracture and mild to moderate cognitive impairment (MMSE 17-26) are recruited at the end of inpatient rehabilitation. The four-month intervention consists of (a) an individually tailored, progressive home exercise program and physical activity promotion delivered by professional instructors and lay instructors (two home visits per week) and (b) a long-term care counselling approach addressing unmet care needs, pleasurable activities, and caregiver issues if needed. Primary outcome parameters are physical activity, measured as daily walking duration with an accelerometer-based activity monitor (activPAL™) over 72 h, and functional performance, assessed with Short Physical Performance Battery sum scores. Secondary outcome parameters are fear of falling, fall related self-efficacy, falls, quality of life, depression and activity of daily living. Data are collected at the end of rehabilitation, before the intervention at the patient's home (baseline), after four months (post-intervention), and seven months (follow-up). In addition to completer and intent-to-treat analyses of outcomes, economic data and incremental cost-effectiveness are analysed. DISCUSSION: Existing service models of volunteer services and legal counselling provided by care counsellors were considered when developing the intervention protocol. Therefore, it should be feasible to translate and deliver the intervention into real-world practice if it has been demonstrated to be effective.

Care challenges in older general hospital patients : Impact of cognitive impairment and other patient-related factors.

BACKGROUND: Older general hospital patients, particularly those with cognitive impairment, frequently experience adverse events and other care complications during their stay. As these findings have so far been based on small and selected patient samples, the aim of the present study was to provide reliable data on a) the prevalence of adverse care issues (summarized under the term care challenges) in older general hospital patients and on b) associated patient-related risk factors (e.g. cognitive impairment). METHODS: A cross-sectional representative study comprising 1469 patients aged ≥65 years from 33 randomly selected general hospitals in southern Germany (GHoSt). Data collection included the use of different data sources, e.g. structured interviews with responsible nursing staff concerning care challenges and procedures for determining the patients' cognitive status. RESULTS: Care challenges were statistically significantly (p < 0.001) more often reported for patients with dementia and/or delirium (87.5%) and mild cognitive impairment (47.9%) compared to cognitively unimpaired patients (24.6%). Adjusted odds ratios suggested cognitive impairment, impaired activities of daily living, receiving long-term care and unplanned admission as significant patient-related risk factors for care challenges. Furthermore, the occurrence of such issues was associated with the application of physical restraints, support from relatives, prescription of psycholeptics and specialist consultations. CONCLUSION: The findings suggest a strong impact of different degrees of cognitive impairment on challenges in care. The results might help to design appropriate training programs for hospital staff and other interventions to prevent or reduce critical situations.

[Factors which influence the position towards euthanasia : Results of a representative survey among older people in Germany]. / Einflussfaktoren auf die Positionierung gegenüber Sterbehilfe : Ergebnisse einer repräsentativen Studie in der Altenbevölkerung.

BACKGROUND: Until now older adults have not been a target group for surveys regarding their personal attitudes towards euthanasia, although they are closest to chronic illness and death. OBJECTIVE: To determine the attitudes of older adults towards euthanasia and controversial topics in the context of illness, euthanasia and care (e. g. palliative care) on the basis of a representative sample. MATERIAL AND METHODS: The study was based on a postal survey of a representative random sample of the population aged 65 years and older (n = 3500) from a city in southern Germany using a standardized questionnaire. RESULTS: A total of 1068 persons completed the questionnaire (response rate 30.5%). Assisted death was supported by 74.2% of the respondants and assisted suicide by 80.4%. According to multiple logistic regression analysis the support decreased with increasing strength of religious faith and a non-German country of origin. Of the participants 53.3% were worried about being a burden to their family, especially people with a limited state of health. People who shared this concern showed significantly more support for both types of euthanasia. More than 40% feared that people with severe and incurable illnesses would be more likely to be forced into a premature death (slippery slope argument). This concern was associated with a decreasing support of euthanasia. CONCLUSION: The results indicate that the strong approval of the legalization of assisted death and assisted suicide by older people is motivated not only by their desire for a self-determined death but also by fears and concerns. The findings have important implications for counseling, palliative care and treatment.

[Dementia friendly care services in general hospitals : Representative results of the general hospital study (GHoSt)]. / Demenzsensible Versorgungsangebote im Allgemeinkrankenhaus : Repräsentative Ergebnisse aus der General Hospital Study (GHoSt).

BACKGROUND: Mostly model projects report on special care services and procedures for general hospital patients with cognitive impairment. The objective of this study was to determine the frequency of special care services and procedures in general hospitals on the basis of a representative cross-sectional study. METHODS: From a list of all general hospitals in southern Germany we randomly selected a specified number of hospitals und somatic wards. The hospitals were visited and all older patients on the selected wards on that day were included in the study. Information about care services and their utilization was collected with standardized instruments. RESULTS: A total of 33 general hospitals and 172 wards participated in the study. The patient sample included 1469 persons over 65 (mean age 78.6 years) and 40% of the patients showed cognitive impairments. The staff reported that the most frequent measures for patients with cognitive impairments concerned patients with wandering behavior (63.1%), efforts to involve the patients' relatives to help with their daily care (60.1%), conducting nonintrusive interviews to identify cognitive impairments (59.9%), allocation to other rooms (58%) and visual aids for place orientation of patients (50.6%). In accordance with earlier studies our results show that other dementia friendly services implemented in pilot projects were rare. The existing special services for patients with cognitive impairment were rarely used by the patients or their relatives. DISCUSSION: The results demonstrate the urgent need to improve special care services and routines for identification of elderly patients with cognitive impairment and risk of delirium in general hospitals.

The 6-Item Cognitive Impairment Test as a bedside screening for dementia in general hospital patients: results of the General Hospital Study (GHoSt).

OBJECTIVE: The objective of this study was to examine the psychometric quality of the 6-Item Cognitive Impairment Test (6CIT) as a bedside screening for the detection of dementia in general hospital patients. METHOD: Participants (N = 1,440) were inpatients aged ≥65 of 33 randomly selected general hospitals in Southern Germany. The 6CIT was conducted at bedside, and dementia was diagnosed according to DSM-IV. Nursing staff was asked to rate the patients' cognitive status, and previous diagnoses of dementia were extracted from medical records. Completion rates and validity statistics were calculated. RESULTS: Two-hundred seventy patients had dementia. Cases with delirium but no dementia were excluded. Feasibility was 97.9% and 83.3% for patients without and with dementia, respectively, and decreased from moderate (93.8%) to severe dementia (53%). The area under the curve of the 6CIT was 0.98. Sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were calculated for the cutoffs 7/8 (0.96, 0.82, 0.85, 0.52, 0.99) and 10/11 (0.88, 0.95, 0.94, 0.76, 0.98). The nurse ratings and medical records information had lower validity statistics. Logistic regression analyses revealed that the 6CIT statistically significantly provided information above nurse ratings and medical records. Twenty-five and 37 additional patients were correctly classified by the 7/8 and 10/11 cutoffs, respectively. CONCLUSION: The 6CIT is a feasible and valid screening tool for the detection of dementia in older general hospital patients. The 6CIT outperformed the nurse ratings of cognitive status and dementia diagnoses from medical records, suggesting that standardized screening may have benefits with regard to case finding.

Current alcohol consumption and its relationship to incident dementia: results from a 3-year follow-up study among primary care attenders aged 75 years and older.

OBJECTIVE: to investigate prospectively the relationship between current alcohol consumption (quantity and type of alcohol) and incident overall dementia and Alzheimer dementia. METHOD: the study is based on individuals (75+) attending general practitioners in Germany: 3,202 subjects free of dementia were studied at baseline, 1.5 years and 3 years later by means of structured clinical interviews including detailed assessment of current alcohol consumption and DSM-IV dementia diagnoses. Associations between alcohol consumption (in grams of ethanol), type of alcohol (wine, beer, mixed alcohol beverages) and incident dementia were examined using Cox proportional hazard models, controlling for several confounders. RESULTS: incident overall dementia occurred in 217 of 3,202 participants over a mean follow-up period of 3 years. Significant relationships were found between alcohol consumption (prevalence at baseline: 50.0%) and incident overall dementia (adjusted hazard ratio (HR) 0.71, 95% CI 0.53-0.96), respectively, incident Alzheimer dementia (adjusted HR 0.58, 95% CI 0.38-0.89). With regard to quantity of alcohol and type of alcohol, all hazard ratios were found to be lower than 1. CONCLUSION: in agreement with meta-analyses that include younger age groups, our study suggests that light-to-moderate alcohol consumption is inversely related to incident dementia, also among individuals aged 75 years and older.

Evaluation of special and traditional dementia care in nursing homes: results from a cross-sectional study in Germany.

OBJECTIVE: Two-thirds of all residents in nursing homes in Germany suffer from some type of dementia. We investigated whether or not dementia patients receiving special (segregated or partially segregated) care exhibited a better quality of life than their counterparts residing in traditional nursing homes. METHODS: In a cross-sectional study in 28 special dementia care facilities in the city of Hamburg (admission criterion: mobile dementia patients with behaviour problems) 594 residents were compared to a group of nursing home residents with dementia (n = 573) in 11 randomly selected nursing homes who were receiving traditional integrative care. Primary features such as cognitive and functional impairment, and behaviour problems were assessed by qualified nursing staff. RESULTS: Controlling for confounding variables, for dementia patients in special care units as compared to a reference group in traditional integrative care, the level of volunteer caregiver involvement was higher and there was more social contact to staff, fewer physical restraints, more involvement in home activities, and more frequent use of psychiatrists. There was no significant difference between the two care settings with regard to overall use of psychotropic drugs, however, residents in special dementia care used antipsychotics significantly less often and antidepressants more often. CONCLUSIONS: Significant differences for a number of indicators of the quality of life point in favour of special dementia care. Future evaluation studies ought to examine not only the general efficacy of types of care designed especially for dementia patients but also the efficacy of the respective individual components (i.e. caregiver ratio).

Transition from inpatient rehabilitation to the home environment in cognitively impaired older persons after hip fracture.

OBJECTIVE: To investigate short-term changes in clinical characteristics in the transition period between geriatric inpatient rehabilitation and independent living at home in older patients with hip/pelvic fracture and cognitive impairment. DESIGN: Longitudinal observational study. SUBJECTS: A total of 127 multi-morbid, older patients with hip/pelvic fracture and cognitive impairment. METHODS: Physical performance, fall-related self-efficacy, fear of falling, depressive symptoms, quality of life, and pain were assessed before discharge from geriatric inpatient rehabilitation and at home. RESULTS: During the transition period (median 18.5 days; interquartile range 14-25 days), 25 participants dropped out due to admission to a nursing home (n = 11), withdrawal of consent (n = 8), death (n = 2), severe disease (n = 2), or other reasons (n = 2). Physical performance improved (p ≤ 0.001), while fall-related self-efficacy (p = 0.040) and fear of falling (p = 0.004) deteriorated. Depressive symptoms, quality of life, and pain did not change. Improvement in physical performance was associated with lower age, lower baseline physical performance, less baseline fear of falling, and living alone. CONCLUSION: While significant improvements in physical performance indicate a high potential for further enhancements in the majority of participants following inpatient rehabilitation, a considerable subgroup dropped out, partly indicating a negative trajectory in this vulnerable patient group. Sustained physical training or promotion of activity at home may further support rehabilitation in patients with hip/pelvic fracture and cognitive impairment.

At-risk alcohol drinking in primary care patients aged 75 years and older.

BACKGROUND: Little is known about the prevalence and risk factors of alcohol problems among older people (especially those aged 75 years and more). The aims of this study were to report alcohol consumption patterns and to determine their association with socio-demographic variables and health characteristics. METHOD: 3224 non-demented subjects aged 75 and over and attending general practitioners (GPs) (n = 138) in an urban area of Germany were studied by structured clinical interviews including detailed assessment of alcohol consumption patterns distinguishing between abstainers, moderate drinkers and at-risk drinkers (>20 g of alcohol for women and >30 g of alcohol for men). RESULTS: A high proportion (50.1%) of the sample were abstainers, 43.4% were moderate drinkers. The prevalence of at-risk alcohol consumption was 6.5% (95% CI 5.6-7.4). Rates were significantly higher for men (12.1%; 95% CI 10.2-14.0) compared to women (3.6%; 95% CI 2.8-4.4). After full adjustment for confounding variables we found that compared to moderate drinking abstaining from alcohol was significantly associated with female gender, lower education, and mobility impairment. Compared to moderate drinking at-risk drinking was significantly higher among men, individuals with a liver disease, and current smokers. CONCLUSIONS: Multivariate analysis revealed that, apart from liver disease, at-risk drinking in a non-demented population aged 75 and over was associated with relatively good physical and mental health. Nevertheless, public prevention measures should focus on at-risk drinkers to make them aware of potential risks of high alcohol consumption in old age.

Day-to-day variability of multiple sensor-based physical activity parameters in older persons with dementia.

OBJECTIVE: To investigate the day-to-day variability of various sensor-based physical activity (PA) parameters and to analyze effects of weekdays vs. weekend days as well as the influence of concomitant factors (gender, living conditions, cognitive status, physical performance, and level of PA) in multi-morbid, older persons with mild-to-moderate stage dementia. METHODS: In 53 participants, PA was recorded on three consecutive days. Day-to-day variability was estimated by calculating intraclass correlation coefficients (ICCs) for two consecutive days each (Friday-Saturday, Saturday-Sunday). RESULTS: Almost all non-walking parameters (lying time, sitting time, standing time, active time, inactive time, and sit-to-stand transitions) showed a consistently low day-to-day variability for Friday-Saturday as well as Saturday-Sunday (ICCs: .60-.96) and hence remained almost unaffected by specific days of the week and concomitant factors. Only the sub-analysis by level of PA revealed slightly deviating results (ICCs: .38-.89). The walking parameters (walking time, walking episodes, and steps) revealed a higher day-to-day variability for Friday-Saturday (ICCs: .01-.40) and a generally lower variability for Saturday-Sunday (ICCs: -.08 - .88), also depending on the respective concomitant factors. CONCLUSIONS: Two consecutive days are adequate to reliably assess non-walking parameters, whereas walking parameters showed higher day-to-day variability with a relevant influence of type of days and concomitant factors.

The selection and definition of indicators in public health monitoring for the 65+ age group in Germany.

Selecting relevant indicators is an important step in the development of public health monitoring for older people. Indicators can be used to combine information comprehensively from various data sources and enable recurring, comparable findings to be made about the health of older people. Indicators were systematically compiled from existing international monitoring systems. An indicator set on health in old age was developed using a multistage, structured consensus-based process together with an interdisciplinary panel of experts. The resulting 18 indicators were assigned to three health areas: (1) environmental factors, (2) activities and participation, and (3) personal factors. Data sources that can be used for the indicators are the health surveys within the framework of the Robert Koch Institute's (RKI) health monitoring system, as well as surveys from other research institutes and official statistics. In the future, the indicator set is to be developed further and integrated into an overall approach that is geared towards health reporting and the monitoring of chronic diseases in all phases of life.

The Prevalence of Dementia and Cognitive Impairment in Hospitals.

BACKGROUND: The care of elderly patients with comorbid dementia poses an increasing challenge in the acute inpatient setting, yet there remains a lack of representative studies on the prevalence and distribution of dementia in general hospitals. METHODS: We conducted a cross-sectional study of patients aged 65 and older in randomly selected general hospitals in southern Germany. Patients were excluded if they were in an intensive care unit or isolation unit or if they were on specialized wards for psychiatry, neurology, or geriatric medicine. The findings are derived from patient interviews, neuropsychological testing, standardized rating scales, questioning of nursing staff, and the patients' medical records. RESULTS: 1469 patients on 172 inpatient wards of 33 hospitals were studied. 40.0% of them (95% confidence interval, [36.2; 43.7]) had at least mild cognitive impairment. The point-prevalence of dementing illnesses was 18.4% [16.3; 20.7]. Delirium, most often on the basis of dementia, was present in 5.1% [3.9; 6.7]. 60.0% had no cognitive impairment. Dementia was more common among patients of very advanced age, those who were dependent on nursing care, those who lived in old-age or nursing homes, and those with a low level of education. Among patients with dementia, only 36.7% had a documented diagnosis of dementia in the medical record. Patients with dementia were treated more often for dehydration, electrolyte disturbances, urinary tract infections, contusions, and bone fractures, as well as for symptoms and findings of an unknown nature, and much less often for cancer or musculoskeletal diseases. CONCLUSION: Two out of five elderly patients in general hospitals suffer from a cognitive disturbance. Patients with severe impairments such as dementia or delirium often need special care. Guidelines and model projects offer approaches by which the inpatient care of patients with comorbid dementia can be improved.

[Prevalence of dementia and medical care in German nursing homes: a nationally representative survey]. / Prävalenz von Demenzen und ärztliche Versorgung in deutschen Pflegeheimen: eine bundesweite repräsentative Studie.

OBJECTIVE: The study aimed to determine the prevalence of dementia and the degree of medical care among residents of nursing homes based on a nationally representative sample of nursing homes in Germany for the first time. METHODS: Based on a probability sample of 609 long-term care institutions in Germany, we drew a sample of 86 facilities by applying a two-stage random procedure. All residents of the participating care facilities were comprehensively assessed by qualified nurses using a standardized Care and Behavior Assessment (CBA). RESULTS: Of the 4,481 residents assessed in 58 care facilities (mean age 82.6 years;78 % female) on average 68.6 % (95 % CI: 67.0 - 69.8) were affected by a dementia-syndrome, 56.6 % by a severe dementia-syndrome. There were frequent contacts between residents and general practitioners, but provision of specialized medical care seemed to be deficient in many aspects. CONCLUSION: People with dementia form the major group of residents in German nursing homes. The study provides important data on need for care and health care planning.
