The effect of depressive symptoms on quality of life and its different facets in the oldest age population: evidence from the AgeQualiDe prospective cohort study.

PURPOSE: The present study aims to investigate the prospective effect of depressive symptoms on overall QoL in the oldest age group, taking into account its different facets. METHODS: Data were derived from the multicenter prospective AgeCoDe/AgeQualiDe cohort study, including data from follow-up 7-9 and n = 580 individuals 85 years of age and older. Overall QoL and its facets were assessed using the WHOQOL-OLD instrument. The short form of the geriatric depression scale (GDS-15) was applied to assess depressive symptoms. Cognitively impaired individuals were excluded. Linear mixed-effects models were used to assess the effect of depressive symptoms on QoL. RESULTS: Depressive symptoms were significantly associated with overall QoL and each of the different facets of WHOQOL-OLD, also after adjustment for time and sociodemographic characteristics such as age, gender, education, marital status, living situation, and cognitive status. Higher age and single as well as divorced marital status were also associated with a lower QoL. CONCLUSION: This work provides comprehensive longitudinal results on the relationship between depressive symptoms and QoL in the oldest age population. The results underscore the relevance of tailored and targeted care planning and the development of customized interventions.

The association of general practitioners' awareness of depression and anxiety with change in quality of life in heart failure patients: results of the prospective observational RECODE-HF cohort study.

BACKGROUND: Depression and anxiety are more prevalent in patients with heart failure (HF) than in the general population and reduce quality of life (QoL); therefore, clinical guidelines recommend screening HF patients for depression/anxiety. OBJECTIVE: We investigated, whether the general practitioners' (GPs) awareness of patients' symptoms of depression and/or anxiety (psychosocial distress) was associated with a change in QoL. METHODS: In this prospective observational study, we recruited 3,129 primary care HF patients in Germany. Patients completed baseline and 12-month follow-up questionnaires. Their GPs were interviewed. We identified 666 patients with psychosocial distress and compared 2 groups by analysis of covariance: 235 patients with psychosocial distress whose GP was aware of the psychosocial distress and 431 patients with psychosocial distress whose GP was unaware of such distress. Primary outcome was the change in QoL, assessed by the EQ-5D visual analogue scale. RESULTS: Patients with psychosocial distress showed lower baseline QoL than those without (45.9 vs 64.1; P < 0.001). Within the patients with psychosocial distress, the GPs' awareness of psychosocial distress was not associated with improvement of QoL (F = 1.285; P = 0.258) or remission of psychosocial distress (odds ratio = 0.887; P = 0.608). CONCLUSION: We found no association between the GPs' awareness of psychosocial distress and change in QoL. Although data for effective treatments of depression in HF are currently insufficient, psychosocial distress strongly impairs the QoL in HF patients. These findings might influence the development of clinical practice guidelines in HF.

Social Support and Functional Decline in the Oldest Old.

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.

Factors Leading to Institutionalization among the Oldest Old: Longitudinal Findings from the AgeCoDe-AgeQualiDe Study.

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.

GPs' views on the use of depression screening and GP-targeted feedback: a qualitative study.

PURPOSE: The first aim of this qualitative study was to identify general practitioners' (GPs') views on depression screening combined with GP-targeted feedback in primary care. The second aim was to determine the needs and preferences of GPs with respect to GP-targeted feedback to enhance the efficacy of depression screening. METHODS: A semistructured qualitative interview was conducted with officially registered GPs in Hamburg (Germany). Interviews were audio recorded and transcribed verbatim. An inductive approach was used to code the transcripts. RESULTS: Nine GPs (27 to 70 years; 5 male) from Hamburg, Germany, participated. Regarding depression screening combined with GP-targeted feedback, five thematic groups were identified: application of screening; screening and patient-physician relationships; GPs' attitudes towards screening; benefits and concerns related to screening; and GPs' needs and preferences regarding feedback. While the negative aspects of screening can be described in rather general terms (e.g., screening determines the mental health competence, screening threatens the doctor-patient relationship, revealing questions harm the patients), its advantages were very specific (e.g., promoting the identification of undetected cases, relief of the daily workload, wider communication channel to reach more patients). Standardized GP-targeted feedback of the screening results was perceived as helpful and purposeful. GPs preferred feedback materials that eased their clinical workload (e.g., short text with visuals, pictures, or images). CONCLUSION: Addressing GPs' needs is essential when implementing depression screening tools in clinical practice. To overcome prejudices and enhance the efficacy of screening, further education for GPs on the purpose and application on depression screening may be needed. Standardized GP-targeted feedback in combination with depression screening could be the missing link to improve the detection of depression in primary care.

Patient involvement in developing a patient-targeted feedback intervention after depression screening in primary care within the randomized controlled trial GET.FEEDBACK.GP.

BACKGROUND: Patient and public involvement (PPI) is increasingly required in mental health services research. To empower patients to actively address depression, the GET.FEEDBACK.GP study evaluates a patient-targeted feedback intervention after depression screening using the Patient Health Questionnaire (PHQ-9). OBJECTIVE: To refine the patient-targeted feedback from a previous study within a participatory research team (PRT) by conducting workshops to investigate patients' needs and preferences for feedback. To evaluate the process and outcome of PPI. DESIGN: Patient and public involvement was carried out on the levels of collaboration and consultation. A PRT of patient partners and researchers planned and conducted three workshops with patients. Patients' needs were investigated using a focus group. Participants prioritized needs, discussed feedback drafts and evaluated two drafts using cognitive debriefings. Researchers of the PRT communicated the results at project level. PPI was evaluated using the Public and Patient Engagement Evaluation Tools (PPEET). SETTING AND PARTICIPANTS: A purposeful sampling of N = 12 patients with experiences of depression participated in at least one workshop. RESULTS: Relevant content-related needs about feedback (eg no distinction between severe and moderate symptoms), recommendations for action and patient-relevant information were considered. Needs for comprehensible, valuing, nonstigmatizing language and design elements (eg dimensional bar) were implemented. Workshops and PRT were positively evaluated. DISCUSSION AND CONCLUSIONS: Patient and public involvement influenced the content, wording and design of the feedback. Strengths include two levels of PPI, methodical diversity and purposeful sampling. Limitations include the lack of inclusion of patients who are unaware of their depression. The evaluated PPI concept can be useful for future studies.

The effect of COVID-19 pandemic and lockdown on consultation numbers, consultation reasons and performed services in primary care: results of a longitudinal observational study.

OBJECTIVES: The aims of our study were to describe the effect of the COVID-19 pandemic and lockdown on primary care in Germany regarding the number of consultations, the prevalence of specific reasons for consultation presented by the patients, and the frequency of specific services performed by the GP. METHODS: We conducted a longitudinal observational study based on standardised GP interviews in a quota sampling design comparing the time before the COVID-19 pandemic (12 June 2015 to 27 April 2017) with the time during lockdown (21 April to 14 July 2020). The sample included GPs in urban and rural areas 120 km around Hamburg, Germany, and was stratified by region type and administrative districts. Differences in the consultation numbers were analysed by multivariate linear regressions in mixed models adjusted for random effects on the levels of the administrative districts and GP practices. RESULTS: One hundred ten GPs participated in the follow-up, corresponding to 52.1% of the baseline. Primary care practices in 32 of the 37 selected administrative districts (86.5%) could be represented in both assessments. At baseline, GPs reported 199.6 ± 96.9 consultations per week, which was significantly reduced during COVID-19 lockdown by 49.0% to 101.8 ± 67.6 consultations per week (p < 0.001). During lockdown, the frequency of five reasons for consultation (-43.0% to -31.5%) and eleven services (-56.6% to -33.5%) had significantly decreased. The multilevel, multivariable analyses showed an average reduction of 94.6 consultations per week (p < 0.001). CONCLUSIONS: We observed a dramatic reduction of the number of consultations in primary care. This effect was independent of age, sex and specialty of the GP and independent of the practice location in urban or rural areas. Consultations for complaints like low back pain, gastrointestinal complaints, vertigo or fatigue and services like house calls/calls at nursing homes, wound treatments, pain therapy or screening examinations for the early detection of chronic diseases were particularly affected.

Prognostic factors associated with quality of life in heart failure patients considering the use of the generic EQ-5D-5L™ in primary care: new follow-up results of the observational RECODE-HF study.

BACKGROUND: The implementation of care concepts fitting the needs of patients with chronic heart failure (HF) remains challenging. In this context, psycho-emotional well-being is not routinely assessed, and under-researched despite indications that it is of great relevance for, e.g., acceptance, adherence, and prognosis. The aim of this study was to observe clinical characteristics for their prognostic utility in HF patients, and to compare the patients' health-related quality of life (QoL) with German population norm values. METHODS: The current post-hoc analysis was performed on data collected amongst participants of the RECODE-HF study who had fully answered the EQ-5D-5L™ items at both baseline and 12 months (n = 2354). The status in the patients' self-assessment items, EQ-5D visual analog scale (VAS) and EQ-5D index was categorized into worse/unchanged/improved. General linear mixed models (GLMM) with logit link were applied. Subgroups included 630 patients (26.8%) screened positive and 1724 patients (73.2%) screened negative for psychosocial distress (PSD). RESULTS: The 12-months change in EQ-5D index, generally resulting from change in individual EQ-5D items, additionally associated not only with high NYHA class but sociodemographics (employment/living alone/GP practice years) (96.2% correctly classified in GLMM). The 12- months change in individual QoL aspects showed associations with age*NYHA, gender, body-mass index, and comorbidities dyslipidemia, myocardial infarction, asthma/chronic pulmonary disease. Important social roles were reflected in particular when HF patients lived alone or the doctor mentioned to the patient that the patient had HF. Patients with/without PSD differed in some sociodemographic and clinical parameters. However, no influence of PSD could be demonstrated in the 12-month follow-up of the EQ-5D-5L™. Nonetheless, comparison of the 12-months QoL with general German population norm values by age groups < 75 years and 75+ showed markedly health restrictions in HF patients in all EQ-5D-5L™ aspects. CONCLUSION: Our analysis revealed different prognostic factors primarily associated with change of burden in different QoL aspects in HF patients. In GP practice it is important to consider in addition to the overall day-related VAS all the individual health-related QoL aspects to take a holistic view of the patient, as well as to pay particular attention to the interrelation of individual characteristics.

Help-seeking for psychological distress and its association with anxiety in the oldest old - results from the AgeQualiDe cohort study.

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.

Mild cognitive impairment and quality of life in the oldest old: a closer look.

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.

Association of depression and anxiety with adherence in primary care patients with heart failure-cross-sectional results of the observational RECODE-HF cohort study.

BACKGROUND: Psychological distress has a negative impact on the prognosis and quality of life for patients with heart failure. We investigated the association between psychological distress and the patients' adherence to medical treatment (medication adherence) and self-care advice (lifestyle adherence) in heart failure. We further examined whether there are different factors associated with low medication compared to low lifestyle adherence. METHOD: This secondary analysis of the RECODE-HF cohort study analyzed baseline data of 3099 primary care heart failure patients aged 74 ± 10 years, 44.5 % female. Using multivariable regression, factors relating to medication and lifestyle adherence were investigated in order to estimate the extent to which these factors confound the association between psychological distress and adherence. RESULTS: Psychological distress was significantly associated with poorer medication adherence but not with lifestyle adherence after controlling for confounders. We identified different factors associated with medication compared to lifestyle adherence. A higher body mass index, a less developed social network, living alone, fewer chronic co-morbidities and unawareness of the heart failure diagnosis were only related to lower lifestyle adherence. Higher education was associated with poorer medication adherence. Male sex, younger age, lower self-efficacy and less familiar relation with the general practitioner were common factors associated with both lower medication and lifestyle adherence. CONCLUSION: Promising factors for increasing medication adherence (reduction of psychological distress) and lifestyle adherence (explaining the patient his/her heart failure diagnosis more than once and increase in the patients' self-efficacy), which were found in this cross-sectional study, must be further investigated in longitudinal studies.

Determinants of incident dementia in different old age groups: results of the prospective AgeCoDe/AgeQualiDe study.

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.

Frequent attendance in primary care in the oldest old: evidence from the AgeCoDe-AgeQualiDe study.

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.

Correlates of hospitalization among the oldest old: results of the AgeCoDe-AgeQualiDe prospective cohort study.

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.

Association of anxiety symptoms with health care use and costs in people aged 85 and over.

OBJECTIVE: To analyze the association of anxiety symptoms with health care use and costs in people aged 85 and older. METHODS: Baseline data from AgeQualiDe (N = 856), a multicenter prospective cohort study of primary care patients aged 85 and older, were analyzed. Anxiety symptoms (Geriatric Anxiety Inventory-Short Form) and health care use were assessed via questionnaires. Health care use was monetarily valued using German unit costs to obtain sectoral (inpatient, outpatient, nursing care, medical supplies, and medication) and total costs. Health care use and costs were analyzed in regression models as a function of anxiety symptoms, as well as relevant covariates (predisposing, enabling, and other need characteristics based on the Behavioral Model of Health Care Use). RESULTS: On a descriptive level, people with increased anxiety symptoms (12% of the sample) incurred on average € 10 909 (SD: 16 023) in the last 6 months, 31% more than those without increased anxiety (€ 8303, SD: 11 175; P = 0.12). Adjusting for predisposing, enabling, and other need characteristics, anxiety symptoms were not significantly associated with health care use or costs. Specifically, need characteristics (morbidity, cognitive decline, and functional impairment) were associated with total or sectoral costs, depending on the cost category analyzed. CONCLUSION: In a sample of people of the oldest-old age group, the severity of anxiety symptoms was not associated with health care use or costs, when adjusting for relevant covariates. A longitudinal analysis could assess whether a change in anxiety symptom severity is associated with health care use or costs in old age.

Quality of life assessment in patients with heart failure: validity of the German version of the generic EQ-5D-5L™.

BACKGROUND: Chronic heart failure patients typically suffer from tremendous strain and are managed mainly in primary care. New care concepts adapted to the severity of heart failure are a challenge and need to consider health-related quality of life aspects. This is the first psychometric validation of the German EQ-5D-5L™ as a generic instrument for assessing health-related quality of life (HRQOL) in a primary care heart failure patient sample. METHODS: Confirmatory factor analysis (CFA) was performed on the baseline EQ-5D-5L™ data from the RECODE-HF study (responses to all items from n = 3225 of 3778 patients). Basic CFA models for HRQOL were calculated based on the EQ-5D-5L™ items using the maximum likelihood (ML) and the asymptotic distribution-free method. In an extended CFA, physical activity and depression were added. The basic CFA ML model was verified for the reduced number of cases of the extended CFA model (n = 3064). In analyses of variance the association of the EQ-5D-5L™ visual analogue scale (VAS) and both the German and the British EQ-5D-5L™ crosswalk index with the SF-36 measure of general health were examined. The discriminant validity was analysed using Pearson's chi-squared tests applying the New York Heart Association classification, for the VAS and indices analyses of variance were calculated. RESULTS: In the basic CFA models the root mean square error of approximation was 0.095 with the ML method, and 0.081 with the asymptotic distribution-free method (Comparative Fit Index > 0.90 for both). Physical activity and depression were confirmed as influential factors in the extended model. The VAS and indices were strongly associated with the SF-36 measure of general health (partial eta-squared 0.525/0.454/0.481; all p <  0.001; n = 3155/3210/3210, respectively), also for physical activity and depression when included together (partial eta-squared 0.050, 0.200/0.047, 0.213/0.051 and 0.270; all p <  0.001; n = 3015/n = 3064/n = 3064, respectively). The discriminant validity analyses showed p-values < 0.001 and small to moderate effect sizes for all EQ-5D-5L™ items. Analyses of variance demonstrated moderate effect sizes for the VAS and indices (0.067/0.087/0.084; all p <  0.001; n = 3110/3171/3171). CONCLUSION: The German EQ-5D-5L™ is a suitable method for assessing HRQOL in heart failure patients.

Importance of comorbidities in the treatment of primary care patients with heart failure-Baseline results of the observational RECODE-HF Study.

Background: Both non-cardiac and cardiac comorbidities are related to the prognosis of chronic heart failure (HF), but so far little is known about the impact of comorbidities on treatment difficulties in routine care. Objectives: To investigate which comorbidities are associated with treatment difficulties in primary care. We hypothesized that somatic comorbidities as well as psychosocial distress are associated with treatment difficulties. Methods: In this baseline analysis of data of the observational RECODE-HF study, HF patients were recruited via primary care practices in two German sites. They received a questionnaire by mail to measure psychosocial distress. Each patient's GP was interviewed by phone regarding the patient's comorbidities and treatment difficulties. Logistic regression analyses controlled for GP cluster effects were calculated to investigate the association between comorbidities/psychosocial distress and treatment difficulties. Results: The 3282 patients of 285 GPs included in the analysis were aged 74.2 (±10.1) years and had a mean number of 4.6 (±2.4) comorbidities. GPs reported treatment difficulties in 32.5% of the patients. Allergies/drug intolerance [odds ratio (ORs)=2.0], asthma/chronic obstructive pulmonary disease (ORs=1.4), renal insufficiency (ORs=1.3), atherosclerosis/peripheral arterial occlusive disease (ORs=1.3) and cardiac arrhythmias (ORs=1.2) as well as patient-reported psychosocial distress (ORs=1.2), HF severity (ORs=3.7-1.6) and age (ORs=0.98) were associated with treatment difficulties. Conclusion: Five somatic comorbidity groups as well as patient-reported psychosocial distress were significantly associated with a higher risk of GP-reported treatment difficulties. Further efforts to address comorbidities in clinical guidelines could be built on these results.

Disentangling the complex relation of disability and depressive symptoms in old age - findings of a multicenter prospective cohort study in Germany.

BACKGROUND: Most of the previous studies attempted to disentangle the relationship between disability and depressive symptoms were limited to observation periods of only few years. Moreover, evidence is missing regarding the complex co-occurrence of disability and depressive symptoms in old age in Germany. In order to close the research gap, we aimed at disentangling the complex co-occurrence of disability and depressive symptoms in old age in Germany over a longer time frame. METHODS: Based on data from a representative survey of the German general population aged 75 years and older, the course of disability as well as depressive symptoms was observed every 1.5 years over six waves. While disability was quantified by the Lawton and Brody Instrumental Activities of Daily Living scale, the Geriatric Depression Scale was used to measure depressive symptoms. Taking into account the complex co-occurrence of depressive symptoms and disability, a panel vector autoregressive model was used. By taking the first differences, unobserved heterogeneity was taken into account. RESULTS: In the total sample and in both sexes, we revealed a robust positive association between an initial change in depressive symptoms and subsequent changes in disability. No robust association between an initial change in disability and a subsequent change in depressive symptoms was detected. CONCLUSION: Our findings highlight the importance of changes in depressive symptoms for future changes in disability in old age.

(In-)formal caregivers' and general practitioners' views on hospitalizations of people with dementia - an exploratory qualitative interview study.

BACKGROUND: Dementia is an irreversible chronic disease with wide-ranging effects on patients', caregivers' and families' lives. Hospitalizations are significant events for people with dementia. They tend to have poorer outcomes compared to those without dementia. Most of the previous studies focused on diagnoses leading to hospitalizations using claims data. Further factors (e.g. context factors) for hospitalizations are not reproduced in this data. Therefore, we investigated the factors leading to hospitalization with an explorative, qualitative study design. METHODS: We interviewed informal caregivers (N = 12), general practitioners (GPs, N = 12) and formal caregivers (N = 5) of 12 persons with dementia using a semi-structured interview guideline. The persons with dementia were sampled using criteria regarding their living situation (home care vs. nursing home care) and gender. The transcripts were analyzed using the method of structuring content analysis. RESULTS: Almost none of the hospitalizations, discussed with the (in-)formal caregivers and GPs, seemed to have been preventable or seemed unjustifiable from the interviewees' points of view. We identified several dementia-specific factors promoting hospitalizations (e.g. the neglect of constricted mobility, the declining ability to communicate about symptoms/accidents and the shift of responsibility from person with dementia to informal or formal caregivers) and context-specific factors promoting hospitalizations (e.g. qualification of nursing home personal, the non-availability of the GP and hospitalizations for examinations/treatments also available in ambulatory settings). Hospitalizations were always the result of the interrelation of two factors: illnesses/accidents and context factors. The impact of both seems to be stronger in presence of dementia. CONCLUSIONS: Points for action in terms of reducing hospitalization rates were: better qualified nurses, a 24-h-GP-emergency service and better compensation for ambulatory monitoring/treatments and house calls. Many hospitalizations of people with dementia cannot be prevented. Therefore, hospital staffs need to be better prepared to handle patients with dementia in order to reduce the negative effects of hospitalizations.

General practitioners' awareness of depressive symptomatology is not associated with quality of life in heart failure patients - cross-sectional results of the observational RECODE-HF Study.

BACKGROUND: Depression is a common comorbidity in patients with chronic heart failure (HF) and linked to a wider range of symptoms which, in turn, are linked to a decreased health-related quality of life (HRQOL). Treatment of depression might improve HRQOL but detecting depression is difficult due to the symptom overlap between HF and depression. Therefore, clinical guidelines recommend to routinely screen for depression in HF patients. No studies have so far investigated the treatment after getting aware of a depressive symptomatology and its correlation with HRQOL in primary care HF patients. Therefore, we examined the factors linked to depression treatment and those linked to HRQOL in HF patients. We hypothesized that GPs' awareness of depressive symptomatology was associated with depression treatment and HRQOL in HF patients. METHODS: For this observational study, HF patients were recruited in primary care practices and filled out a questionnaire including PHQ-9 and HADS. A total of 574 patients screened positive for depressive symptomatology. Their GPs were interviewed by phone regarding the patients' comorbidities and potential depression treatment. Descriptive and regression analysis were performed. RESULTS: GPs reported various types of depression treatments (including dialogue/counselling by the GP him/herself in 31.8% of the patients). The reported rates differed considerably between GP-reported initiated treatment and patient-reported utilised treatment regarding psychotherapy (16.4% vs. 9.5%) and pharmacotherapy (61.2% vs. 30.3%). The GPs' awareness of depressive symptomatology was significantly associated with the likelihood of receiving pharmacotherapy (OR 2.8; p < 0.001) but not psychotherapy. The patient's HRQOL was not significantly associated with the GPs' awareness of depression. CONCLUSION: GPs should be aware of the gap between GP-initiated and patient-utilised depression treatments in patients with chronic HF, which might lead to an undersupply of depression treatment. It remains to be investigated why GPs' awareness of depressive symptomatology is not linked to patients' HRQOL. We hypothesize that GPs are aware of cases with reduced HRQOL (which improves under depression treatment) and unaware of cases whose depression do not significantly impair HRQOL, resulting in comparable levels of HRQOL in both groups. This hypothesis needs to be further investigated.
