RESUMEN
PURPOSE: To examine the association of sociodemographic and health-related determinants with social isolation in relation to family and friends in the oldest-old. METHODS: Database was the multi-center prospective AgeCoDe/AgeQualiDe cohort study assessed at follow-up wave 5 (N = 1148; mean age 86.6 years (SD 3.0); 67% female). Social isolation was assessed using the short form of the Lubben Social Network Scale (LSNS-6). The LSNS-6 contains two sets of items establishing psychometrically separable subscales for isolation from family and friends (ranges 0-15 points), with lower scores indicating higher isolation. Cross-sectional linear (OLS) regression analyses were used to examine multivariate associations of sociodemographic and health-related determinants with social isolation from family and friends. RESULTS: Overall, n = 395 participants (34.6%) were considered socially isolated. On average, isolation was higher from friends (mean 6.0, SD 3.8) than from family (mean 8.0, SD 3.5). Regression results revealed that in relation to family, males were more socially isolated than females (ß = - 0.68, 95% CI - 1.08, - 0.28). Concerning friends, increased age led to more isolation (ß = - 0.12, 95% CI - 0.19, - 0.05) and functional activities of daily living to less isolation (ß = 0.36, 95% CI 0.09, 0.64). Independent of the social context, depression severity was associated with more social isolation, whereas cognitive functioning was associated with less social isolation. CONCLUSIONS: Different determinants unequally affect social isolation in relation to family and friends. The context of the social network should be incorporated more strongly regarding the detection and prevention of social isolation to sustain mental and physical health.
RESUMEN
BACKGROUND: Nursing home residents (NHR) show high rates of polypharmacy. The HIOPP-3-iTBX study is the first cRCT on medication optimization in nursing homes (NH) in Germany. The intervention did not result in a reduction of PIM and/or antipsychotics. This analysis looks at structure quality in the HIOPP-3-iTBX study participants. AIMS: Evaluation of structure quality as part of a cluster-randomized controlled intervention study. METHODS: Structure quality in multiprofessional teams from n = 44 NH (n = 44 NH directors, n = 91 family doctors (FD), and n = 52 pharmacies with n = 62 pharmacists) was assessed using self-designed questionnaires at baseline. Main aspects of the questionnaires related to the qualification of participants, quality management, the medication process and size of the facilities. All completed questionnaires were included. number of PIM/antipsychotics was drawn from the baseline medication analysis in 692 NHR. Data were analyzed by descriptive statistics and mixed model logistic regression. RESULTS: The presence of a nurse with one of the additional qualifications pain nurse or Zertifiziertes Curriculum (Zercur) Geriatrie in the participating NH was associated with a lower risk for the prescription of PIM/antipsychotics. No association between any characteristic in the other participants at baseline was observed. CONCLUSIONS AND DISCUSSION: The results support the known role of nursing qualification in the quality and safety of care. Further studies need to look more closely at how use is made of the additional qualifications within the multiprofessional teams. Perspectively, the results can contribute to the development of quality standards in NH in Germany.

PURPOSE: The aim of this study was to examine the longitudinal within-association between social support and health-related quality of life among the oldest old. METHODS: Longitudinal data (follow-up waves 7 to 9) were used from the multicenter prospective cohort study "Needs, health service use, costs and health-related quality of life in a large sample of oldest-old primary care patients (85 +)" (AgeQualiDe). n = 648 individuals were included in the analytical sample. At FU wave 7, mean age was 88.8 years (SD: 2.9 years, from 85 to 99 years). Social support was quantified using the Lubben Social Network Scale (6-item version). Health-related quality of life was assessed using the EQ-5D-3L including problems in five health dimensions, and its visual analogue scale (EQ VAS). It was adjusted for several covariates in conditional logistic and linear fixed effects regressions. RESULTS: Intraindividual decreases in social support were associated with an increased likelihood of developing problems in 'self-care', 'usual activities', 'pain/discomfort' and 'anxiety/depression' (within individuals over time). In contrast, intraindividual changes in social support were not associated with intraindividual changes in the EQ VAS score. CONCLUSION: Findings indicate a longitudinal intraindividual association between social support and problems, but only in some health dimensions. Further research in this area based on longitudinal studies among the oldest old (from different countries) is required.

INTRODUCTION: Due to the strong association between old age and the need for long-term care, the number of individuals in need for care is projected to increase noticeably. The aim of this study was to examine the determinants of institutionalization among the oldest old longitudinally. METHODS: Longitudinal data (follow-up [FU] wave 7-9) were gathered from a multicenter prospective cohort study ("Study on needs, health service use, costs and health-related quality of life in a large sample of oldest old primary care patients [85+]," AgeQualiDe). At FU wave 7, in 2014, complete measures were available for 763 individuals. The average age was 88.9 (standard deviation 2.9) years (range 85-100), and 68% were female. Sociodemographic and health-related independent variables (e.g., depressive symptoms or functioning) were included in the regression model. Institutionalization (admission to assisted living home or nursing home) was used as an outcome measure. Logistic random-effects models were used. RESULTS: Regressions revealed that among oldest old, the odds of being institutionalized were lower for men (odds ratio [OR] = 0.03; 95% confidence interval [CI] 0.00-0.16). Institutionalization was associated with an increased age (OR = 1.27; 95% CI 1.04-1.55). Additionally, widowed individuals (ref. non-widowed) had higher odds of being institutionalized (OR = 8.95; 95% CI 1.61-49.81). Institutionalization was also associated with functional decline (OR = 0.16; 95% CI 0.11-0.23), whereas it was not significantly associated with cognitive decline, depressive symptoms, and social support. CONCLUSION: Our findings stress the importance of gender, age, widowhood, and functional decline for institutionalization among the oldest old. Preventing or at least postponing functional decline might help to delay institutionalization as far as possible.

OBJECTIVE: Longitudinal studies investigating the link between social support and functional decline are limited among the oldest old. Thus, the aim of this study was to examine whether changes in social support are associated with functional decline among the oldest old longitudinally using panel regression models. METHODS: Longitudinal data from 3 waves (waves 7, 8, and 9) of a multicenter prospective cohort study covering primary care patients aged ≥85 years were used. In the analytical sample, n equaled 624 individuals. The validated Lawton and Brody Instrumental Activities of Daily Living (IADL) scale and the well-established Barthel Index (ADL) were used to quantify functional status. The psychometrically sound Lubben Social Network Scale was used to measure social support. Several potential confounders such as age, marital status, cognitive decline, or depressive symptoms were included in the fixed effects (FE) regression models. RESULTS: Linear FE regressions showed that a decrease in social support is associated with functional decline (IADL: ß = 0.03, p < 0.05; ADL: ß = 0.27, p < 0.05) in men but not in women. With IADL as outcome measure, the interaction term (sex × social support) achieved statistical significance (p < 0.01). With regard to covariates, functional decline (IADL and ADL) was consistently associated with increasing age, an increase in the number of chronic conditions (except for women [ADL]), and cognitive decline (except for men [ADL]). Furthermore, functional decline (ADL) was associated with an increase in depressive symptoms. DISCUSSION: Our findings highlight the meaning of social support for functional status among the oldest old. Finding ways to sustain social support in highest age may be a promising approach in order to postpone functional decline.

OBJECTIVES: Depressive symptoms and chronic pain are common among patients with multimorbidity creating a complex medical condition for both the patient and the general practitioner. Perceived social support may function as a protective measure.To examine the impact of perceived social support as a potential moderator between depressive symptoms and pain intensity and pain disability in daily activities in multimorbid patients aged 75+. METHOD: Data from 3,189 patients of the German longitudinal cohort study MultiCare were obtained at baseline and follow-ups during 5 years. Multilevel linear mixed-effects analyses were conducted for pain intensity (model 1) and pain disability in daily activities (model 2). The interaction term social support by depression score was included to test for moderation. RESULTS: The interaction between social support and depressive symptoms was significantly associated with the pain intensity score 0.41 (SE=.17; 95-CI[.08;.74]) but not with the pain disability score 0.35 (SE=.19; 95-CI[-.01;.72]). Additionally, men and individuals with medium or higher educational level showed reduced pain intensity and disability scores. Pain disability scores increased with age and depressive symptoms. Increased pain scores were also found for body mass index and burden of multimorbidity. CONCLUSION: Perceived social support amplified the association of depressive symptoms on pain intensity and did not show a protective function. The high scores of perceived social support among the participants may point to the practice of secondary gain due to the patients immense health burden.

OBJECTIVES: Autonomy (defined as self-governance; not equivalent to independence) is relevant to well-being and psychological functioning. However, there is a lack of research on individuals aged >85 years and their perception of autonomy when receiving informal care. This study aims to answer the question if and how the receipt of informal care is associated with perceived autonomy of individuals aged over 85 years. METHOD: A cross-sectional study was conducted with data from follow-up 9 of the AgeQualiDe study (2015/2016), which is a multi-centric prospective cohort study in Germany. The analytical sample included 570 participants aged >85 years and with a score of ≥ 19 on the Mini-Mental-State-Examination. Perceived autonomy was assessed with the Perceived Autonomy in Old Age Scale. Receipt of care was assessed as performance of at least one care task (help with basic and instrumental activities of daily living, and supervision) by relatives or friends. Sociodemographic information, mental health, functional level and receipt of professional ambulatory care were controlled for. RESULTS: Unadjusted and adjusted linear regression analyses indicated a significant negative association between receipt of informal care and perceived autonomy. The results remained stable in sensitivity analyses; no significant interaction effect was found for gender or education. CONCLUSION: Findings indicate that informal care recipients aged >85 years perceive lower autonomy compared to those not receiving care. Additional or other forms of support, and improving the care relationship and communication might be considered to support autonomy of care recipients aged >85 years.

BACKGROUND: Depression in older adults is becoming an increasing concern. As depressive symptoms change over time, it is important to understand the determinants of change in depressive symptoms. The aim of our study is to use a longitudinal study design to explore the predictors of change, remission and incident depression in older patients with multimorbidity. METHODS: Data from the MultiCare cohort study were used. The cohort studied 3,189 multimorbid general practice patients aged 65-85. Data were collected during personal interviews. Depressive symptoms were assessed using the Geriatric Depression Scale (GDS-15). Predictors of change in depressive symptoms were determined using multivariate linear regression, while multivariate logistic regression was used to analyze predictors of remission and incident depression. Models included depressive symptoms at baseline and follow-up, socio-demographics and data on health status and social support. RESULTS: Overall, 2,746 participants with complete follow-up data were analyzed. Mean age was 74.2 years, 59.2% were female, and 11.3% were classified as depressed at baseline. Burden of multimorbidity and social support were statistically significant predictors in all regression analyses. Further predictors of change in depressive symptoms were: income, pain, nursing grade, self-rated health and self-efficacy. LIMITATIONS: The sample size for prediction of remission limited statistical certainty. Assessment of depressive symptoms using GDS-15 differs from routine clinical diagnoses of depression. CONCLUSIONS: Predictors of change in depressive symptoms in older multimorbid patients are similar to those predicting remission and incident depression, and do not seem to differ significantly from other older patient populations with depressive symptoms.

OBJECTIVES: There is a lack of studies identifying the correlates of institutionalization specifically among the oldest old. Therefore, our aim was to fill this gap in knowledge. METHODS: Cross-sectional data (Follow up wave 9; n = 633 observations in the analytical sample) were used from the multicenter prospective cohort study "Needs, health service use, costs and health-related quality of life in a large sample of oldest-old primary care patients (85+)" Correlates of institutionalization among the oldest old-Evidence from a multicenter cohort study. The sample consists of primary care patients aged 86 years and over (mean 90.5 years, SD: 2.9 years). Sociodemographic and health-related independent variables were included in our regression model. Institutionalization was defined as living in a nursing home or an old-age home (not including assisted living facilities). RESULTS: Out of the 633 participants, 502 individuals (79.3%) did not live in an institutionalized setting, whereas 73 individuals (20.7%) lived in an institutionalized setting. Multiple logistic regressions showed that the likelihood of institutionalization increased with being divorced/widowed/single (compared to being married; OR: 5.35 [95% CI: 1.75-16.36]), the presence of social isolation (OR: 2.07 [1.20-3.59]), more depressive symptoms (OR: 1.11 [1.01-1.23]), increased cognitive impairment (OR: 1.67 [1.31-2.15]) and higher levels of frailty (OR: 1.48 [1.07-2.06]). CONCLUSION: The study findings identified various sociodemographic and health-related factors associated with institutionalization among the oldest old. Longitudinal studies are required to gain further insights into these associations.

OBJECTIVES: Previous studies have observed protective effects of high mental demands at work on cognitive functioning and dementia risk. However, it is unclear what types of demands drive this effect and whether this effect is subject to a person's genetic risk. We investigated to what extent eight different types of mental demands at work together with the APOE e4 allele, a major risk gene for late-onset Alzheimer's disease, affect cognitive functioning in late life. METHODS/DESIGN: The population-based German Study on Ageing, Cognition, and Dementia in Primary Care Patients (AgeCoDe, n = 2 154) followed cognitively healthy individuals aged 75 years and older in seven assessment waves. Cognitive functioning was assessed via the mini-mental status examination. RESULTS: Mixed-effects modeling (adjusted for education, gender, marital status, stroke, depression, and diabetes) indicated that participants who had an occupational history of working in jobs with high compared to low demands in "Language & Knowledge", "Pattern detection", "Information processing", and "Service" had a slower cognitive decline. APOE e4-allele carriers had an accelerated cognitive decline, but this decline was significantly smaller if they had a medium compared to a low level of demands in contrast to non-carriers. CONCLUSIONS: Our longitudinal observations suggest that cognitive decline could be slowed by an intellectually enriched lifestyle even in risk gene carriers. Fostering intellectual engagement throughout the life-course could be a key prevention initiative to promote better cognitive health in old age.

INTRODUCTION: There is a lack of studies examining the link between perceived autonomy and frailty among the oldest old. Therefore, our objective was to fill this gap. METHODS: Data were used from the multicenter prospective cohort study "Needs, health service use, costs and health-related quality of life in a large sample of oldest-old primary care patients (85+)" (AgeQualiDe; follow-up [FU] wave 9; n = 510 observations in the analytical sample). The average age was 90.3 years (SD: 2.7 years). The Canadian Study of Health and Aging (CSHA) Clinical Frailty Scale (CFS) was used to assess frailty. Socioeconomic and health-related covariates were included in our regression model. The autonomy scale developed by Schwarzer was used to assess perceived autonomy in old age. RESULTS: Adjusting for various confounders, multiple linear regressions showed that lower perceived autonomy was associated with increased levels of frailty (total sample: ß = -0.13, p < 0.001; women: ß = -0.14, p < 0.001; and men: ß = -0.12, p < 0.001). Furthermore, lower perceived autonomy was associated with more depressive symptoms, higher cognitive impairment, and being institutionalized (except for men) in the total sample and in both sexes, but it was not significantly associated with age, sex, marital status, educational level, and social support. CONCLUSION: Findings indicate that frailty is associated with lower autonomy among the oldest old. More generally, while health-related factors were consistently associated with autonomy, sociodemographic factors (except for being institutionalized) were not associated with autonomy among the oldest old. We should be aware of the strong association between autonomy and physical as well as mental health in very old age.

BACKGROUND: It is almost unknown whether the driving status is associated with HRQOL among individuals in highest age. AIMS: Based on a multicenter prospective cohort study, the objective of this study was to examine whether the driving status is associated with health-related quality of life (HRQOL) among the oldest old in Germany. METHODS: Cross-sectional data from follow-up wave 9 (n = 544) were derived from the "Study on Needs, health service use, costs and health-related quality of life in a large sample of oldest-old primary care patients (85+)" (AgeQualiDe). Average age was 90.3 years (± 2.7; 86 to 101 years). The current driver status (no; yes) was used in our analysis. The EuroQoL EQ-5D questionnaire was used to assess HRQOL in this study. RESULTS: Regression analysis showed that being a current driver was associated with the absence of problems in 'self-care' [OR 0.41 (95%-CI 0.17 to 0.98)], and 'usual activities' [OR 0.48 (0.26 to 0.90)], whereas it was not significantly associated with problems in 'pain/discomfort' [OR 0.82 (0.47 to 1.45)] and 'anxiety/depression' [OR 0.71 (0.36 to 1.39)]. Being a current driver was marginally significantly associated with the absence of problems in 'mobility' [OR 0.60 (0.34 to 1.06)]. While being a current driver was not associated with the EQ-VAS in the main model, it was positively associated with the driving status (ß = 5.00, p < .05) when functional impairment was removed from the main model. DISCUSSION: Our findings provide first evidence for an association between driving status and HRQOL among the oldest old. CONCLUSIONS: Future longitudinal studies are required to evaluate a possible causal relationship between driving status and HRQOL in very old individuals.

Objectives: This study aimed to examine aspects of help-seeking for psychological distress and its association with increased anxiety symptoms in the oldest old.Method: Baseline data from AgeQualiDe, a multicenter cohort study of people aged 85 and over recruited in primary care, were analyzed. Help-seeking for psychological distress (items from the Camberwell Assessment of Need for the Elderly) was analyzed using ordinal and logistic regression models as a function of increased anxiety symptoms (Geriatric Anxiety Inventory-Short Form ≥ 3), as well as relevant socio-demographic and health-related covariates.Results:N = 155 (18.1% of the sample) reported having experienced psychological distress recently and were thus included in the analysis. Among those, 26.5% reported experiencing increased anxiety symptoms. On a descriptive level, 76.8% sought informal, 29.0% sought formal, and 18.1% sought no help for psychological distress. In covariate-adjusted regression models, increased anxiety was significantly associated with increased use of informal support (OR: 2.92, 95% CI: 1.31-6.48), but was neither associated with formal (OR: 0.72, 95% CI: 0.26-1.97) nor no help-seeking (OR: 0.28, 95% CI: 0.08-1.05).Conclusion: A large proportion of those experiencing psychological distress sought support from informal sources in this study. Anxiety symptoms in the oldest old were associated with the increased use of informal support, but not formal support or no help-seeking. Training and support for people providing informal help to those with mental health problems should be promoted to reduce a possible burden. However, future research addressing underlying mechanisms is needed.

PURPOSE: To describe health status and health state utilities measured by the EQ-5D-3L in a population-based sample of individuals aged 85 + in Germany, and to analyze associations with basic socio-demographic variables. METHODS: Cross-sectional data from follow-up wave 7 (n = 761) of the German AgeCoDe Study were used. The EQ-5D-3L questionnaire was used to record problems in five health dimensions, its visual analogue scale (EQ VAS) was used to record self-rated health status, and the German EQ-5D-3L index was used to derive health state utilities. RESULTS: Mean age of respondents was 88.9 years (SD 2.9; range 85 to 100), 67.4% were female. 81.9% reported problems in at least one of the EQ-5D dimensions, with 15.3% reporting extreme problems. Most frequent were problems with pain/discomfort (64.8%), followed by mobility (62.5%), usual activities (42.6%), self-care (28.2%), and anxiety/depression (20.5%). Mean EQ VAS score was 62.4 (SD 18.8), and mean EQ-5D index was 0.77 (SD 0.24). Multiple regression analysis showed associations of problem frequency in various EQ-5D dimensions with age, gender, living situation, marital status, and education. The EQ VAS score was negatively associated with age (ß = - 0.56; p < 0.05) and female gender (ß = - 3.49; p < 0.05). The EQ-5D index was negatively associated with not living in the community (ß = - 0.10; p < 0.001) and being single (ß = - 0.09; p < 0.05). CONCLUSIONS: The results show a substantially impaired health status of the oldest-old population. The data can be used for comparing health status of population groups as well as for health economic models.

PURPOSE: Mild cognitive impairment (MCI) is a widespread phenomenon, especially affecting older individuals. We will analyze in how far MCI affects different facets of quality of life (QOL). METHODS: We used a sample of 903 participants (110 with MCI) from the fifth follow-up of the German Study on Ageing, Cognition, and Dementia in Primary Care Patients (AgeCoDe), a prospective longitudinal study, to analyze the effects of MCI on different facets of the WHOQOL-OLD. We controlled for age, gender, marital status, education, living situation, daily living skills, and the ability to walk, see, and hear. RESULTS: Univariate analyses showed that individuals with MCI exhibited lower QOL with regard to the facets autonomy; past, present, and future activities; social participation; and intimacy, but less fears related to death and dying. No significant difference was shown with regard to the facet sensory abilities. In multivariate analyses controlling for age, gender, marital status, education, living situation, daily living skills, and the ability to walk, see and hear, MCI-status was significantly associated with QOL in the facet autonomy. CONCLUSION: Effects of MCI go beyond cognition and significantly impact the lives of those affected. Further research and practice will benefit from utilizing specific facets of QOL rather than a total score.

INTRODUCTION: There is a lack of studies investigating the link between time-varying factors associated with changes in frailty scores in very old age longitudinally. This is important because the level of frailty is associated with subsequent morbidity and mortality. OBJECTIVE: To examine time-dependent predictors of frailty among the oldest old using a longitudinal approach. METHODS: Longitudinal data were drawn from the multicentre prospective cohort study "Study on Needs, health service use, costs and health-related quality of life in a large sample of oldest-old primary care patients (85+)" (AgeQualiDe), covering primary care patients aged 85 years and over. Three waves were used (from follow-up, FU, wave 7 to FU wave 9 [with 10 months between each wave]; 1,301 observations in the analytical sample). Frailty was assessed using the Canadian Study of Health and Aging (CSHA) Clinical Frailty Scale (CFS). As explanatory variables, we included sociodemographic factors (marital status and age), social isolation as well as health-related variables (depression, dementia, and chronic diseases) in a regression analysis. RESULTS: In total, 18.9% of the individuals were mildly frail, 12.4% of the individuals were moderately frail, and 0.4% of the individuals were severely frail at FU wave 7. Fixed effects regressions revealed that increases in frailty were associated with increases in age (ß = 0.23, p < 0.001), and dementia (ß = 0.84, p < 0.01), as well as increases in chronic conditions (ß = 0.03, p = 0.058). CONCLUSION: The study findings particularly emphasize the importance of changes in age, probably chronic conditions as well as dementia for frailty. Future research is required to elucidate the underlying mechanisms. Furthermore, future longitudinal studies based on panel regression models are required to confirm our findings.

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.

BACKGROUND: There are very few studies examining the determinants of frequent attendance in primary care among the oldest old. AIMS: The purpose of this study was to determine the characteristics of frequent attendance among individuals aged 85 years or older. METHODS: Cross-sectional data stem from the multicenter prospective cohort "Study on needs, health service use, costs and health-related quality of life in a large sample of oldest old primary care patients (85 +)" (AgeQualiDe). This study covers very old primary care patients (n = 861, mean age of 89.0 years ± 2.9; 85-100 years). The number of self-reported GP visits in the preceding 3 months was used to quantify frequent attenders. We defined patients in the top decile as frequent attenders. RESULTS: Multiple logistic regressions showed that frequent attendance was associated with more chronic diseases (adjusted OR 1.12, 95% CI 1.01-1.23), worse functioning (OR 0.97, 95% CI 0.95-0.99), worries about one's financial situation (OR 2.20, 95% CI 1.07-4.53) and it was inversely associated with depression (OR 0.26, 95% CI 0.08-0.80). DISCUSSION: In contrast to studies based on younger samples, different factors were associated with frequent users in our study, showing that it is important to study the determinants of frequent attendance among the oldest old. CONCLUSION: In Germany, among the group of the oldest old, frequent attendance was positively associated with worse physical health status (e.g., number of chronic diseases), but negatively with depression. This might indicate that the German health care system is responsive to the physical, but not psychological needs of the oldest old.

BACKGROUND: Hospitalization is a key driver of health care costs. Thus far, there are only a few longitudinal studies investigating whether changes in explanatory variables lead to hospitalization. Moreover, these longitudinal studies did not focus on individuals in highest age. AIM: The purpose of the current study was to examine the correlates of hospitalization among the oldest old in Germany longitudinally. METHODS: A multicenter prospective cohort study ["Study on Needs, health service use, costs and health-related quality of life in a large sample of oldest-old primary care patients (85+)", AgeQualiDe]. Primary care patients ≥ 85 years took part [n = 861 at follow-up (FU) 7, average age of 89.0 years; 85-100 years]. Two waves were used. Hospitalization in the last 6 months was used as outcome measure. Well-established scales were used to quantify the independent variables such as Instrumental Activities of Daily Living Scale, Global Deterioration Scale or Geriatric Depression Scale. RESULTS: Logistic random effects regressions showed that the probability of hospitalization in the preceding 6 months significantly increased with increases in the social network, more depressive symptoms, functional decline, and increase in chronic conditions, whereas it was not significantly associated with age, sex, marital status, education, and cognitive impairment. Social networks moderate the relationship between functional decline and hospitalization. DISCUSSION: The results of the present longitudinal study emphasize the association of depressive symptoms, functional decline, more social networks, and chronic conditions with hospitalization among the oldest old. CONCLUSIONS: Treatments with the aim to reduce or postpone these factors might also help to reduce hospitalization.

INTRODUCTION: Subjective cognitive decline (SCD) is a risk condition for dementia, including dementia of Alzheimer type (DAT). METHODS: We report sensitivity, specificity, positive and negative predictive values (PPV, NPV) for conversion to all-cause dementia, and DAT in different SCD types (decline in memory, assocated worries, longitudinal consitency, of the AgeCoDe study (n = 2.402, 12 years follow-up). RESULTS: 82.7% of those converting to any dementia and 84.4% of those converting with DAT at follow-up, reported memory decline and fulfilled criteria of SCD at least at one time point before. SCD with worries at two consecutive time points showed a specificity of 92.2% for any dementia and also for DAT as well as a PPV of 44.3% for any dementia and of 36.9% for DAT at follow-up at the expense of low sensitivity. DISCUSSION: Different SCD subtypes were either sensitive or specific for future all-cause dementia and DAT in cognitively unimpaired individuals. Modest PPV of the most specific SCD subtypes were achieved in this low prevalence population.
