Objectives: There is an increasing call for a stronger consideration of impairment in instrumental activities of daily living (IADL) in the diagnostic criteria of Mild Cognitive Impairment (MCI) to improve the prediction of dementia. Thus, the aim of the study was to determine the predictive capability of MCI and IADL impairment for incident dementia. Design: Longitudinal cohort study with four assessments at 1.5-year intervals over a period of 4.5 years. Setting: : Primary care medical record registry sample. Participants: As part of the German Study on Ageing, Cognition, and Dementia in Primary Care Patients, a sample of 3,327 patients from general practitioners, aged 75 years and older, was assessed. Measurements: The predictive capability of MCI and IADL impairment for incident dementia was analysed using receiver operating characteristics, Kaplan-Meier survival analyses, and Cox proportional hazards models. Results: MCI and IADL impairment were found to be significantly associated with higher conversion to, shorter time to, and better predictive power for future dementia. Regarding IADL, a significant impact was particularly found for impairment in responsibility for one's own medication, shopping, and housekeeping, and in the ability to use public transport. Conclusions: Combining MCI with IADL impairment significantly improves the prediction of future dementia. Even though information on a set of risk factors is required to achieve a predictive accuracy for dementia in subjects with MCI being clinically useful, IADL impairment should be a very important element of such a risk factor set.

Background: Geriatric rehabilitation aims at increasing physical and social activity and maintaining the functional reserve of older people. However, the continuity of geriatric rehabilitation in the outpatient setting is limited due to a lack of structured aftercare programs. In order to overcome this, a three-month multimodal home-based intervention program (GeRas) was implemented. The aim of this early qualitative process evaluation was to assess GeRas in terms of perceived reach, effectiveness/efficacy, adoption/uptake, implementation, and maintenance/sustainability (Domains within the RE-AIM Framework) from the perspective of patients who received the intervention and healthcare providers who were involved in the delivery of the intervention., Methods: In a qualitative process evaluation, 13 healthcare providers and 10 patients were interviewed throughout the beginning of the implementation period of GeRas to capture early experiences using a semi-structured interview guide. The interview guide and qualitative content analysis was guided by the RE-AIM Framework., Results: The GeRas program was perceived to be largely well implemented and beneficial by healthcare providers and patients. According to healthcare providers, GeRas showed more advantages compared to usual care. Additionally, outcome expectations were mainly met (Domain 1: Effectiveness). However, the implementation of the intervention delivered via the eHealth system was perceived as challenging (Domain 2: Adoption). Nevertheless, the outpatient physical exercise, the outpatient counselling, and the continuous care after discharge improved perceived well-being regardless of the intervention type (Domain 3: Implementation). To facilitate the continued use of GeRas, technical requirements should be created to increase user-friendliness and to motivate patients to continue the training in the long term (Domain 4: Maintenance)., Conclusion: Although initial experiences with the implementation and effectiveness of GeRas were positive in general, organisational and technical issues need to be resolved to enhance sustainable and successful implementation of the GeRas program., Trial Registration: German Clinical Trials Register (DRKS00029559).

Background: The internet has the potential to foster healthy lifestyles and to support chronic disease management. Older adults could benefit from using the internet and other information and communication technology to access health-related information and interventions available online., Objective: The aim of this study was to investigate factors influencing internet use in older and oldest age groups and to determine the frequency of internet use for health-related purposes., Methods: Using data from a nationally representative telephone survey of older adults aged 75 years and over, a sample of 999 people was assessed using structured clinical interviews. Descriptive and binary logistic regression analyses were performed., Results: Overall, 42.6% (418/999) of participants used the internet. Among those, 55.7% (233/417) searched the internet for health-related information. Regression analyses revealed that internet use was significantly associated with younger age (odds ratio [OR] 0.89, 95% CI 0.85-0.92; P<.001), male gender (OR 2.84, 95% CI 2.02-4.00; P<.001), higher education levels (OR 6.69, 95% CI 4.48-9.99; P<.001), a wider social network (OR 1.04, 95% CI 1.01-1.07; P=.01), higher health-related quality of life (OR 1.02, 95% CI 1.00-1.03; P=.006), lower levels of depressive symptoms (OR 0.89, 95% CI 0.80-0.99; P=.04), and higher rates of chronic illness (OR 1.12, 95% CI 1.04-1.21; P<.004)., Conclusions: This study provides population-representative data on internet use in old age in Germany. People in the older and oldest age groups participate in online activities. Understanding the factors that are associated with older adults internet use can contribute to developing tailored interventions and eHealth (electronic health) services to improve well-being in older adults., (©Janine Quittschalle, Janine Stein, Melanie Luppa, Alexander Pabst, Margrit Löbner, Hans-Helmut Koenig, Steffi G Riedel-Heller.

Objectives: To examine the impact of determinants of incident dementia in three different old age groups (75-79, 80-84, 85+years) in Germany., Design: Multicenter prospective AgeCoDe/AgeQualiDe cohort study with baseline and nine follow-up assessments at 1.5-year intervals., Setting: Primary care medical record registry sample., Participants: General practitioners' (GPs) patients aged 75+years at baseline., Measurements: Conduction of standardized interviews including neuropsychological assessment and collection of GP information at each assessment wave. We used age-stratified competing risk regression models (accounting for the competing event of mortality) to assess determinants of incident dementia and age-stratified ordinary least square regressions to quantify the impact of identified determinants on the age at dementia onset., Results: Among 3027 dementia-free GP patients, n = 704 (23.3%) developed dementia during the 13-year study period. Worse cognitive performance and subjective memory decline with related worries at baseline, and the APOE ε4 allele were associated independently with increased dementia risk in all three old age groups. Worse cognitive performance at baseline was also associated with younger age at dementia onset in all three age groups. Other well-known determinants were associated with dementia risk and age at dementia onset only in some or in none of the three old age groups., Conclusions: This study provides further evidence for the age-specific importance of determinants of incident dementia in old age. Such specifics have to be considered more strongly particularly with regard to potential approaches of early detection and prevention of dementia.

Aim: To analyze the association between ceiling effects on the EQ-5D 5L and morbidity in a general population sample., Methods: We used a cross-sectional sample of the German general population (n = 5007) to describe the frequency of health state "11111" and "no problems"-answers on the five single dimensions stratified by the number of diseases for which participants utilized health care during the last 6 months. For the five single dimensions we also used specific criteria to analyze their discriminative ability. A logit-model was applied for a multivariate analysis of ceiling effects., Results: 31% of participants reported the health state "11111." This percentage strongly decreased with increasing morbidity, down to 4.9% if four or more diseases were present. The dimensions "mobility," "usual activities," and "pain/discomfort" showed good discriminative abilities. The dimensions "anxiety/depression" and "self -care" were able to discriminate between different levels of morbidity, but nevertheless showed strong ceiling effects, in particular "self-care.", Conclusion: When analyzing ceiling effects of the EQ-5D 5L, one has to draw attention to morbidity since high proportions of participants indicating the best health state might result from being healthy regarding the dimensions assessed by the EQ-5D, in particular in general population datasets.

Background: Completion of advance directives (ADs) and power of attorney (POA) documents may protect a person's autonomy in future health care situations when the individual lacks decisional capacity. As such situations become naturally much more common in old age, we specifically aimed at providing information on (i) the frequency of ADs/POA in oldest-old individuals and (ii) factors associated with having completed ADs/POA., Methods: We analyzed data of oldest-old primary care patients (85+ years; including community-dwelling and institutionalized individuals) within the German AgeQualiDe study. Patients were initially recruited via their general practitioners (GPs). We calculated frequencies of ADs and POA for health care with 95% confidence intervals (CI) and used multivariable logistic regression analysis to evaluate the association between having ADs and POA and participants' socio-demographic, cognitive, functional, and health-related characteristics., Results: Among 868 GP patients participating in AgeQualiDe (response = 90.9%), n = 161 had dementia and n = 3 were too exhausted/ill to answer the questions. Out of the remaining 704 (81.1%) dementia-free patients (mean age = 88.7 years; SD = 3.0), 69.0% (95%-CI = 65.6-72.4) stated to having ADs and 64.6% (95%-CI = 61.1-68.2) to having a POA for health care. Individual characteristics did not explain much of the variability of the presence/absence of ADs and POA (regression models: Nagelkerke's R 2  = 0.034/0.051). The most frequently stated reasons for not having ADs were that the older adults trust their relatives or physicians to make the right decisions for them when necessary (stated by 59.4% and 44.8% of those without ADs). Among the older adults with ADs, the majority had received assistance in its preparation (79.0%), most frequently from their children/grandchildren (38.3%). Children/grandchildren were also the most frequently stated group of designated persons (76.7%) for those with a POA for health care., Conclusions: Our findings suggest a high dissemination of ADs and POA for health care in the oldest-old in Germany. Some adults without ADs/POA perhaps would have completed advance care documents, if they had had received more information and support. When planning programs to offer advanced care planning to the oldest old, it might be helpful to respond to these specific needs, and also to be sensitive to attitudinal differences in this target group.

Background: For cost-utility analyses, data on health state utilities, as provided by the EQ-5D-3L, is needed but not always available. This study specified mapping algorithms from the Beck Depression Inventory (BDI) index to the EQ-5D-3L index adjusted for specific socio-demographic variables for patients with depressive disorders., Aims of the Study: The objective of this study was to specify mapping algorithms from the BDI index to the preference-based EQ-5D index for patients with depressive disorders, adjusting for specific socio-demographic variables., Methods: A sample of 1,074 consecutive patients with depressive disorders from a psychotherapeutic outpatient clinic was included in the study. Standardized clinical interviews were applied to establish reliable diagnoses. For the prediction of the EQ-5D-3L index from the BDI index and selected patient socio-demographic characteristics, ordinary least squares regression with robust standard errors was used. Model prediction properties were tested using the root mean squared error and repeated random sub-sampling cross-validation., Results: The BDI index predicted the EQ-5D-3L index with a significant proportion of variance explained. The highest model goodness of fit was estimated for models with the BDI index and age as independent variables. The root mean squared error of the predicted EQ-5D-3L index in the validation samples was 0.23 for all models., Discussion: The mean observed EQ-5D-3L index values and the mean predicted EQ-5D-3L index values seemed not to differ between models. However, a reduction of variability using cross-validation led to those (rather) accurate mean predicted values. One limitation of this study was the restricted generalizability. Moreover, some uncertainty was introduced in model predictive performance by usage of a dependent estimation sample for validation., Implications for Further Research: The specified mapping algorithms from the BDI index to the EQ-5D-3L index for patients with depressive disorders are acceptable as approximation in cost-utility analyses. A further validation in independent samples is necessary to obtain more confidence in their performance.

Background: Most published data on out-of-pocket spending on mental health originate from the United States, where insurance payments for mental health have traditionally been much less generous than benefits for other health care services. Given the difference in the structure of health care funding in Europe, it is clearly important to obtain similar information on out-of-pocket expenditure in different European countries., Aim of the Study: To estimate out-of-pocket costs paid by people who receive mental health care in six European countries (Belgium, France, Germany, Italy, the Netherlands, and Spain)., Methods: Of the 8,796 participants in a cross-sectional survey conducted in these six European countries, 1,128 reported having consulted a professional for a mental health problem in the year preceding the interview and provided information on how many times in the past year they consulted each type of provider, and the money they and their family members had paid out-of-pocket for their mental health care. In addition to sociodemographic characteristics, information on mental health status was collected using the CIDI 3.0. Descriptive statistics on out-of-pocket expenditure and share of income across countries were generated. Two-part models were employed to identify the relationship between the different covariates, notably the types of providers consulted, and out-of-pocket expenditure., Results: Overall, 41.0% of those who used services for a mental health problem paid something for the care they received. This represented a minority of respondents in all countries except Belgium (87.9%) and Italy (61.7%). The financial burden of these costs relative to income was found to be low (1.2%), ranging from 0.4% in Germany to 2.3% in France. Out-of-pocket expenditure differed according to the type of providers consulted, with non-physician health professionals and medical specialists being more often associated with significant expenditure., Discussion and Limitations: Although the study is limited principally by data collection from self-report, it is the first of its kind, to our knowledge, and suggests that out-of-pocket costs for mental health care in Europe are relatively low compared to the United States. However, differences between countries exist, which may be partially due to differences in coverage for specialized care., Implications for Health Policies: Consultations with non-physician mental health professionals such as psychologists are expensive for patients, since they are reimbursed to a lesser extent than consultations with physicians, or not reimbursed at all. This limits their role and increases the burden on psychiatrists., Implications for Further Research: Monitoring out-of-pocket spending on mental health, preferably on the basis of administrative data when available, is essential in the current context of cost containment policy, where out-of-pocket spending may be expected to increase.

Background: Maintaining independence in instrumental activities of daily living (IADL) is crucial for older adults. This study explored the association between cognitive and functional performance in general and in single IADL domains. Also, risk factors for developing IADL impairment were assessed., Methods: Here, 3,215 patients aged 75-98 years were included. Data were collected during home visits., Results: Cognitive functioning was associated with IADL both cross-sectionally and longitudinally. Regarding the single IADL domains cross-sectionally, executive functioning was especially associated with shopping, while episodic memory was associated with responsibility for own medication., Conclusion: Reduced performance in neuropsychological tests is associated with a greater risk of current and subsequent functional impairment., (Copyright © 2011 S.

Objective: To assess the negative health consequences and associated costs of cigarette smoking in Germany in 2003 and to compare them with the respective results from 1993., Methods: The number of deaths, years of potential life lost (YPLL), direct medical and indirect costs caused by active cigarette smoking in Germany in 2003 is estimated from a societal perspective. The method is similar to that applied by Welte et al, who estimated the cost of smoking in Germany in 1993. Therefore, a direct comparison of the results was possible. Methodological and data differences between these two publications and their effect on the results are analysed., Results: In 2003, 114,647 deaths and 1.6 million YPLL were attributable to smoking. Total costs were euro21.0 billion, with euro7.5 billion for acute hospital care, inpatient rehabilitation care, ambulatory care and prescribed drugs; euro4.7 billion for the indirect costs of mortality; and euro8.8 billion for costs due to work loss days and early retirement. From 1993 to 2003, the proportionate mortality attributable to smoking remained relatively stable, rising from 13.0% to 13.4%. The smoking-attributable deaths in men is lowered by 13.7% whereas that in women increased by 45.3%. Total real direct costs rose by 35.8%, and total real indirect costs declined by 7.1%, rendering an increase of 4.7% to real total costs. Accountable factors are changes in cigarette smoking prevalence and in disease-specific mortality and morbidity, as well as a rise in general healthcare expenditure., Conclusions: Despite the growing knowledge about the hazards of smoking, the smoking-attributable costs increased in Germany. Further, female mortality attributable to smoking is much higher than it was in 1993.
