Purpose: The aim of this study was to examine the longitudinal association between educational level and frailty prevalence in older adults and to investigate the role of material, biomedical, behavioral, social, and mental factors in explaining this association., Methods: Data over a period of 13 years were used from the Longitudinal Aging Study Amsterdam. The study sample consisted of older adults aged 65 years and above at baseline (n = 1205). Frailty was assessed using Fried's frailty criteria. A relative index of inequality was calculated for the level of education. Longitudinal logistic regression analyses based on multilevel modeling were performed., Results: Older adults with a low educational level had higher odds of being frail compared with those with a high educational level (relative index of inequality odds ratio, 2.94; 95% confidence interval, 1.84-4.71). These differences persisted during 13 years of follow-up. Adjustment for all explanatory factors reduced the effect of educational level on frailty by 76%. Income, self-efficacy, cognitive impairment, obesity, and number of chronic diseases had the largest individual contribution in reducing the effect. Social factors had no substantial contribution., Conclusions: Our findings highlight the need for a multidimensional approach in developing interventions aimed at reducing frailty, especially in lower educated groups., (Copyright © 2014 Elsevier Inc.

In order to provide adequate care for frail older adults in primary care it is essential to have insight into their care needs. Our aim was to describe the met and unmet care needs as perceived by frail older adults using a multi-dimensional needs assessment, and to explore their associations with socio-demographic and health-related characteristics. Cross-sectional baseline data were used from the Frail older Adults: Care in Transition (ACT) study in the Netherlands, consisting of 1137 community dwelling frail older adults aged 65 and above. Patients were recruited through 35 primary care practices. Self-perceived care needs were assessed using the Camberwell Assessment of Need for the Elderly (CANE). Socio-demographic characteristics included age, sex, partner status and educational level. Health-related characteristics included functional capacity, hospital admissions, chronic diseases and the degree of frailty. Frail older adults reported on average 4.2 care needs out of 13 CANE topics, of which 0.5 were unmet. The physical and environmental domain constituted the highest number of needs, but these were mostly met. Unmet needs were mainly found in the psychosocial domain. Regression analyses revealed that Activities of Daily Living (ADL) limitations and a higher frailty score were the most important determinants of both met and unmet care needs. A younger age and a higher educational level were associated with the presence of unmet care needs. In conclusion, most frail older adults in primary care report to receive sufficient help for their physical needs. More attention should be paid to their psychosocial needs., (Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.)

Background: Depressive and anxiety disorders are highly overlapping, heterogeneous conditions that both have been associated with an increased risk of cardiovascular disease (CVD). Cognitive vulnerability traits for these disorders could help to specify what exactly drives CVD risk in depressed and anxious subjects. Our aim is to examine sensitivity to depression or anxiety in association with indicators of subclinical CVD., Methods: Data from 635 participants (aged 20-66 years) of the Netherlands Study of Depression and Anxiety were analyzed. Depression sensitivity was measured by the revised Leiden Index of Depression Sensitivity. Anxiety sensitivity was measured by the Anxiety Sensitivity Index. Subclinical CVD was measured as (1) carotid intima-media thickness and plaque presence using B-mode ultrasonography and (2) central arterial stiffness (augmentation index) using calibrated radial applanation tonometry., Results: After adjustment for sociodemographics, blood pressure, and LDL cholesterol, higher scores of anxiety sensitivity were associated with both increased likelihood of carotid plaques (OR per SD increase=1.34, 95%CI=1.06-1.68) and increased arterial stiffness (β=.06, p=.01). No significant associations were found with carotid intima-media thickness nor for depression sensitivity., Limitations: The cross-sectional design precludes causal inference. Current mood state could have influenced the self-reported sensitivity data., Conclusions: The presence of carotid plaques and central arterial stiffness was especially increased in subjects who tend to be highly fearful of anxiety-related symptoms. These observations suggest that vulnerability to anxiety, rather than to depression, represents a correlate of subclinical CVD., (Copyright © 2012 Elsevier B.V. All rights reserved.)

Background: Crisis is a term frequently used in dementia care lacking a standardized definition. This article systematically reviews existing definitions of crisis in dementia care literature to create a standardized definition that can be utilized for research, policy and clinical practice., Methods: We systematically searched for articles containing definitions of crisis in the context of dementia care. We created an operational framework of crisis based on retrieved definitions. Recommendations to address crisis situations were reviewed and classified according to care settings., Results: Abstracts and titles of 1,113 articles, screened from PubMed and EMBASE, were narrowed down to 27 articles. After review, crisis in dementia was defined as a process where a stressor causes an imbalance requiring an immediate decision to be made which leads to a desired outcome and therefore a resolution of the crisis. If the crisis is not resolved, the cycle continues. Recommendations for resolving crisis involving persons with dementia and their caregivers include awareness therapy after diagnosis and increased contact with general practitioners, case manager consultations, caregiver support and education. Furthermore, nursing home staff should be attuned to the environmental, physical and psychological needs of persons with dementia., Conclusions: This is the first article to review the definition of crisis in the context of dementia care. A review of the literature indicated that the definition of a crisis is idiosyncratic. Therefore, it is difficult to prevent or plan for all crises. We used an operational framework to compile types of crisis stressors and recommendations from the crisis literature based on three different perspectives; the person with the dementia, the caregiver and the healthcare providers.

Objective: Previous studies reported low and inconsistent rates of recognition of anxiety disorders by family physicians (FPs). Our objectives were to examine (a) which combination of indications within medical records most accurately reflects recognition of anxiety disorders and (b) whether patient and FP characteristics were related to recognition., Method: A cross-sectional comparison was made between FPs' registration and a structured diagnostic interview, the Composite International Diagnostic Interview, according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria. Seven definitions of recognition were tested using diagnostic codes, medication data, referral data and free text in medical records. Data were derived from the Netherlands Study of Depression and Anxiety. A total of 816 patients were included., Results: Recognition ranged between 9.1% and 85.8%. A broader definition was associated with a higher recognition rate, but led to more false positives. The best definition comprised diagnostic codes for anxiety disorders and symptoms, strong free-text indications, medication and referral to mental health care. Generalized anxiety disorder was best recognized by this definition. Recognition was better among patients with increased severity, comorbid depression and older age., Conclusion: FPs recognized anxiety disorders better than previously reported when all medical record data were taken into account. However, most patients were nonspecifically labeled as having a mental health problem., (Copyright © 2012 Elsevier Inc. All rights reserved.)

Objective: To estimate and compare the prevalence and incidence of delirium and its risk factors in residents of Dutch nursing homes and residential care homes., Methods: Data were extracted from the Long-Term Care Facility (inter RAI-LTCF) version of the Resident Assessment Instrument, which was filled in a routine care cohort for a total of 3627 residents. 828 residents of six nursing homes and 1365 residents of 23 residential homes were included in the analyses. Delirium was defined as a positive score on the adjusted Nursing Home-CAM., Results: The prevalence of delirium was 8.9% in the nursing homes and 8.2% in the residential homes. The incidence was highest in the nursing homes with 20.7 versus 14.6 per 100 person-years. Multivariate tests of risk factors for developing delirium included chair restraints (OR 2.3; 95% CI 1.27-4.28), dementia (odds ratio (OR) 3.3; 95% confidence interval (CI) 2.03-5.24) and Parkinson's disease (OR 2.3; 95% CI 0.96-5.63) for residents in nursing homes, and dementia (OR 1.8; 95% CI 1.31-2.55) and fall incidents (OR 1.7; 95% CI 1.20-2.48) for residents in residential care homes., Conclusion: The prevalence and incidence of delirium was high in both nursing homes and residential care homes. More focus on modifiable risk factors such as the use of restraints in nursing homes and fall incidents in residential care homes may help to prevent delirium., (Copyright © 2011 John Wiley & Sons, Ltd.)

Background: Although most depressed patients are treated in primary care, not all are recognized as such. This study explores the determinants of (non-)recognition of depression by general practitioners (GPs), with a focus on specific depression symptoms as possible determinants., Methods: Recognition of depression by GPs was investigated in 484 primary care participants of the Netherlands Study of Depression and Anxiety, with a DSM-IV diagnosis of depression in the past year. Recognition (yes/no) by GPs was based on medical file extractions (GP diagnosis of depressive symptoms/depressive disorder and/or use of antidepressants/referral to mental health care). Potential determinants of (non-)recognition (patient, depression, patient-GP interaction, and GP characteristics) were bivariately tested and variables with a p-value ≤0.2 entered into a multilevel multivariate model. Subgroup analysis was performed on 361 respondents with more reliable GP diagnosis data., Results: 60.5% of patients were recognized by their GP. Patients who did not consult their GP for mental problems, and without comorbid anxiety disorder(s) were less often recognized. In the subgroup, where 68.7% was recognized, in addition to these, decreasing number of symptoms of depression and increased appetite were associated with decreased recognition. No GP characteristics were retained in the final model., Limitations: Some data on recognition were collected retrospectively., Conclusions: In addition to patients without a comorbid anxiety disorder or who did not consult their GP for mental problems, GPs less often recognized patients with fewer depression symptoms or with increased appetite. Recognition may be improved by informing/teaching GPs that also increased appetite can be a symptom of depression., (Copyright © 2012 Elsevier B.V. All rights reserved.)

Objective: Optimising care for dementia patients and their informal carers is imperative in light of the impending dementia epidemic. An important aspect of care is accurate recognition and diagnosis of dementia. The aim of this review was to estimate family physicians' diagnostic accuracy at the different stages of dementia., Methods: Pubmed, Embase, CINAHL, PsycINFO and the Cochrane Library were searched for articles comparing family physicians' 'dementia' and 'cognitive impairment' diagnoses in the primary care setting to reference standard dementia diagnoses., Results: Data from six cross-sectional studies of moderate to reasonable methodological quality were extracted for the analysis. One study considered the accuracy of family physicians' recollected diagnoses, and three studies focussed on documented diagnoses. In these four studies, the sensitivity of family physicians' combined diagnostic categories of 'cognitive impairment' together with 'dementia' was 0.48-0.67 for mild dementia and 0.76-0.85 for moderate to severe dementia. The sensitivity of their diagnostic category 'dementia' alone was 0.14-0.33 for mild and 0.28-0.61 for moderate to severe dementia. Specificity was excellent for all severity stages in both comparisons. Three studies examined the accuracy of family physicians' judgement of cognition during consultation. Compared with the studies on recollection and documentation, these studies reported higher sensitivity and lower specificity., Conclusion: Many individuals with dementia are not recognised or not diagnosed as such; particularly mild dementia is under-diagnosed. Collaboration within primary care and education focussing both on knowledge and attitude are recommended to improve the accuracy of family physicians' dementia diagnosis., (Copyright © 2011 John Wiley & Sons, Ltd.)

Objective: Mental health and cardiovascular disease have been associated, whereas the temporal course and underlying mechanisms are still incompletely understood. Our aims were to examine the presence of subclinical atherosclerosis in subjects with depressive or anxiety disorder, also taking into account disorder characteristics (subtype, severity, duration, age of onset, medication)., Methods: The sample included 470 depression or anxiety cases and 179 controls, aged 20-66 years, participating in the Netherlands Study of Depression and Anxiety (NESDA). Diagnoses were assigned using the DSM-IV based Composite International Diagnostic Interview. Carotid intima-media thickness (CIMT) and plaque information were obtained using B-mode ultrasound imaging., Results: Overall, depressive and anxiety disorders were not associated with carotid atherosclerosis. However, age of depression onset was associated with CIMT (total: 0.01 mm per 10 years, P = 0.01; bifurcation: 0.02 mm per 10 years, P = 0.003) and plaque presence (OR = 1.35 per 10 years, 95%CI = 1.02-1.80, P = 0.04). When compared with controls, late-onset (≥ 40 years) depressed had an increased CIMT in the atherosclerosis progression-prone bifurcation segment (0.75 vs. 0.81 mm, P = 0.004)., Conclusions: These findings suggest a distinct pathophysiology of late-onset as compared with early-onset depression, including a vascular component.

Background: Previous estimates of depression recognition in primary care are low and inconsistent. This may be due to registration artifacts and limited extraction efforts. This study investigated a) whether GPs' medical records demonstrate an accurate recognition of depression and b) which combinations of indications within the record most accurately reflect a diagnosis of depression., Methods: GPs' registrations were compared with a reference standard, the Composite International Diagnostic Interview (CIDI), according to DSM-IV criteria. Six definitions of GPs' recognition of depression were tested using diagnostic codes, medication data, referral data and free text in the medical records. The Youden-index was used to select the optimal definition of recognition. Data were derived from the Netherlands Study of Depression and Anxiety. 816 primary care patients from 33 general practitioners were included in the vicinities of Amsterdam and Leiden, The Netherlands., Results: Registration of antidepressant prescriptions was the best single indicator of GPs' recognition of CIDI depression with a recognition rate of 0.43. The best combination of indicators increased the recognition rate to 0.69. All indications except the specific diagnostic codes for 'depressive disorder' and 'depressive feelings' were included in this definition., Limitations: Potential bias due to the selection of participating GPs might have influenced our recognition rates., Conclusion: GPs are aware of mental health problems in most depressed patients, but labeling with specific diagnostic codes is weak. Researchers should consider that diagnostic coding alone is not an accurate measure of the diagnostic ability of depression and strongly underestimates the accuracy of the GP., (Copyright © 2011 Elsevier B.V.

Background: Sophisticated approaches are needed to improve the quality of care for elderly people living in residential care facilities. We determined the effects of multidisciplinary integrated care on the quality of care and quality of life for elderly people in residential care facilities., Methods: We performed a cluster randomized controlled trial involving 10 residential care facilities in the Netherlands that included 340 participating residents with physical or cognitive disabilities. Five of the facilities applied multidisciplinary integrated care, and five provided usual care. The intervention, inspired by the disease management model, consisted of a geriatric assessment of functional health every three months. The assessment included use of the Long-term Care Facility version of the Resident Assessment Instrument by trained nurse-assistants to guide the design of an individualized care plan; discussion of outcomes and care priorities with the family physician, the resident and his or her family; and monthly multidisciplinary meetings with the nurse-assistant, family physician, psychologist and geriatrician to discuss residents with complex needs. The primary outcome was the sum score of 32 risk-adjusted quality-of-care indicators., Results: Compared with the facilities that provided usual care, the intervention facilities had a significantly higher sum score of the 32 quality-of-care indicators (mean difference - 6.7, p = 0.009; a medium effect size of 0.72). They also had significantly higher scores for 11 of the 32 indicators of good care in the areas of communication, delirium, behaviour, continence, pain and use of antipsychotic agents., Interpretation: Multidisciplinary integrated care resulted in improved quality of care for elderly people in residential care facilities compared with usual care., Trial Registration: www.controlled-trials.com trial register no.

Background: It is believed that timely recognition and diagnosis of dementia is a pre-condition for improving care for both older adults with dementia and their informal caregivers. However, diagnosing dementia often occurs late in the disease. This means that a significant number of patients with early symptoms of dementia and their informal caregivers may lack appropriate care., Objectives: To compare the effects of case management and usual care among community-dwelling older adults with early symptoms of dementia and their primary informal caregivers., Design: Randomized controlled trial with measurements at baseline and after 6 and 12 months., Setting: Primary care in West-Friesland, the Netherlands., Participants: 99 pairs of community-dwelling older adults with dementia symptoms (defined as abnormal screening for symptoms of dementia) and their primary informal caregivers., Intervention: 12 months of case management by district nurses for both older adults and informal caregivers versus usual care., Primary Outcome: informal caregiver's sense of competence., Secondary Outcomes: caregiver's quality of life, depressive symptoms, and burden, and patient's quality of life. Process measurements: intervention fidelity and caregiver's satisfaction with the quality of case management., Results: Linear mixed model analyses showed no statistically significant and clinically relevant differences over time between the two groups. The process evaluation revealed that intervention fidelity could have been better. Meanwhile, informal caregivers were satisfied with the quality of case management., Conclusion: This study shows no benefits of case management for older adults with dementia symptoms and their primary informal caregivers. One possible explanation is that case management, which has been recommended among diagnosed dementia patients, may not be beneficial if offered too early. However, on the other hand, it is possible that: (1) case management will be effective in this group if more fully implemented and adapted or aimed at informal caregivers who experience more severe distress and problems; (2) case management is beneficial but that it is not seen in the timeframe studied; (3) case management might have undetected small benefits. This has to be established. Trial registration ISCRTN83135728., (Copyright © 2011 Elsevier Ltd. All rights reserved.)

Background: Arterial stiffness gains attention as a potential mechanism underlying the frequently found association between depression or anxiety and cardiovascular disease. However, observations regarding stiffness and psychopathology were often based on small samples. The current study aimed to examine whether subjects with a diagnosis of depressive or anxiety disorder showed increased stiffness and to explore associations between various psychiatric characteristics and arterial stiffness., Methods: The sample included 449 cases with DSM-IV based lifetime diagnoses of depressive and/or anxiety disorder and 169 control subjects. Subjects were participating in the Netherlands Study of Depression and Anxiety and were aged 20 to 66 years. Characteristics included comorbidity, subtype of disorder, symptom severity and duration, age of onset, and use of antidepressant medication. Arterial stiffness was measured by calibrated radial tonometry (heart rate normalized central augmentation index [AIx75]; in percentage) and carotid M-mode ultrasound (distensibility coefficient)., Results: After adjustment for covariates, AIx75 was increased in current (1-month) depression or anxiety (15.7% vs. 13.3% in control subjects, p = .01). Disorder characteristics associated with AIx75 were depression and anxiety comorbidity (15.3%, p = .02), higher depression severity (β = .10, p < .001) and anxiety severity (β = .10, p < .001), and longer symptom duration (β = .07, p = .01). No significant associations were found between distensibility coefficient and psychopathology., Conclusions: Current depressive or anxiety disorders were associated with a higher central augmentation index, a manifestation of early wave reflection because of arterial stiffness. Exposure to depression and anxiety may therefore enhance the development and progression of atherosclerosis and other cardiovascular conditions., (Copyright © 2011 Society of Biological Psychiatry.

Background: Associations between depression, and possibly anxiety, with cardiovascular disease have been established in the general population and among heart patients. This study examined whether cardiovascular disease was more prevalent among a large cohort of depressed and/or anxious persons. In addition, the role of specific clinical characteristics of depressive and anxiety disorders in the association with cardiovascular disease was explored., Methods: Baseline data from the Netherlands Study of Depression and Anxiety were used, including persons with a current (i.e. past year) or remitted DSM-IV depressive or anxiety disorder (N=2315) and healthy controls (N=492). Additional clinical characteristics (subtype, duration, severity, and psychoactive medication) were assessed. Cardiovascular disease (stroke and coronary heart disease) was assessed using algorithms based on self-report and medication use., Results: Persons with current anxiety disorders showed an about three-fold increased prevalence of coronary heart disease (OR anxiety only=2.70, 95%CI=1.31-5.56; OR comorbid anxiety/depression=3.54, 95%CI=1.79-6.98). No associations were found for persons with depressive disorders only or remitted disorders, nor for stroke. Severity of depressive and anxiety symptoms--but no other clinical characteristics--most strongly indicated increased prevalence of coronary heart disease., Limitations: Cross-sectional design., Conclusions: Within this large psychopathology-based cohort study, prevalence of coronary heart disease was especially increased among persons with anxiety disorders. Increased prevalence of coronary heart disease among depressed persons was largely owing to comorbid anxiety. Anxiety-alone as well as comorbid to depressive disorders-as risk indicator of coronary heart disease deserves more attention in both research and clinical practice., (2010 Elsevier B.V.

Objective: Current evidence regarding the association between psychopathology and subclinical atherosclerosis show inconsistent results. The present study examined whether subclinical atherosclerosis was more prevalent in a large cohort of persons with depressive or anxiety disorders as compared to non-depressed and non-anxious controls., Methods: Baseline data from the Netherlands Study of Depression and Anxiety were used, including 2717 persons, free of clinical cardiovascular disease. Participants had a DSM-IV-based current or remitted depressive (major depressive disorder, dysthymia) or anxiety (social phobia, generalized anxiety disorder, panic disorder, agoraphobia) disorder (n=2115) or were healthy controls (n=602). Additional clinical characteristics (severity, duration, age of onset and medication) were assessed. Ankle-brachial index (ABI) was used as a measure of vascular risk and was categorized as low (1.40), which was previously designated as a cardiovascular risk factor, reflecting arterial stiffness and wall calcification., Results: As compared to normal controls, persons with current (i.e., past year) depressive, anxiety or comorbid depressive and anxiety disorders showed a two- to threefold increased odds of low ABI (OR=2.78, 95% CI=1.05-7.35; OR=3.14, 95% CI=1.25-7.85; OR=2.67, 95% CI=1.09-6.51, respectively). No associations were found with mildly low or high ABI. Also, we did not further find a differential role for symptoms severity, duration, age of onset, and use of psychotropic medication in the link between psychopathology and subclinical atherosclerosis., Conclusion: Persons with current depressive or anxiety disorders were more likely to have subclinical atherosclerosis compared to healthy controls., (Copyright 2010 Elsevier Inc.

Objective: Although community-based studies reported an increased incidence of depression among demented persons compared with non-demented persons, it is not clear whether this relationship also exists among institutionalised elderly persons. The aim of this study was to compare the prevalence of diagnosed depressive disorders and mood symptoms between demented and non-demented residents living in Dutch homes for the elderly., Methods: Cross-sectional analysis in 16 homes for the elderly of routine outcome measurements by trained nurse assistants using the Resident Assessment Instrument (RAI) between January 2007 and April 2008. Nurse assistants recorded all known medical diagnoses including dementia and depression, as well as a structured observation of the presence or absence of 11 mood symptoms over the last 3 days., Results: 313 demented and 463 non-demented residents with complete data were included (99% of all residents, mean age 84 years). 24.6% of participants were diagnosed with a depressive disorder, with no statistically significant difference between demented and non-demented persons (p = 0.237). Mood symptoms were more prevalent in demented residents (p < 0.001, OR 2.14, 95%CI 1.56-2.93). Among residents with mood symptoms, demented residents were less likely to be diagnosed with a depressive disorder than non-demented residents (p = 0.039, OR 0.61, 95%CI 0.38-0.98)., Conclusions: The prevalence of diagnosed depressive disorders was comparable between demented and non-demented residents. However, demented residents suffered more from mood symptoms and may be at risk of under-diagnosis of depression., ((c) 2009 John Wiley & Sons, Ltd.)

Background: Minor depression is common in primary care and associated with increased health care costs. Many mildly depressed patients are prescribed antidepressants, although there is insufficient information on the cost-effectiveness of antidepressants for these patients. The objective of this study was to evaluate whether usual care without antidepressants is equivalent to (i.e. as effective as and as expensive as) usual care with antidepressants in patients with minor or mild-major depression., Methods: Severity of depression was measured using the Montgomery Asberg Depression Rating Scale (MADRS) and quality-adjusted life-years (QALYs) using the EuroQol. Resource use was measured from a societal perspective using cost diaries. Bootstrapping was used to analyze the cost-effectiveness data., Results: Equivalence could not be shown for improvement in MADRS score or QALYs gained at 52 weeks. The mean (95% CI) difference in total costs between usual care without antidepressants and usual care with antidepressants was -euro751 (-3601; 1522). Using an equivalence margin of euro500 equivalence in costs could not be shown. In the cost-effectiveness analyses equivalence also could not be shown., Limitations: This study was underpowered for economic outcomes. Another limitation was the loss-to-follow-up., Conclusions: Although equivalence could not be shown in the costs and cost-effectiveness analyses, 95% confidence intervals also did not show that usual care without antidepressants was vastly superior or inferior to usual care with antidepressants. Therefore, we recommend general practitioners to show restraint when prescribing antidepressants to mildly depressed patients.

The Informant Questionnaire on Cognitive Decline (IQCODE) has been successful in identifying demented persons in a general population. In this study, this questionnaire was used as a self-report screening for dementia symptoms. The object was to investigate the feasibility, homogeneity, and construct validity of self-reports on the IQCODE. Participants were 4823 community-dwelling older adults who received an IQCODE-SR. Feasibility was assessed on the basis of response rate, the proportion of missing data for each item, and the number of persons who received help in completing the questionnaire. Homogeneity was checked with Cronbach's alpha. To investigate construct validity, hypotheses on performance of the IQCODE-SR were tested. Feasibility was acceptable, with a response rate of 58.9%. Missing answers per item ranged from 2.5% to 7.3%, and 915 of 2841 participants received help in completing the questionnaire. Homogeneity was good, with Cronbach's alpha = .94. The majority of hypotheses on construct validity were confirmed. It was concluded that the IQCODE-SR meets the basic requirements of a good measurement instrument.

Background: Depression is a highly prevalent condition that is associated with high levels of work absenteeism and high health care costs. Most patients are treated in primary care. A large group of patients prefers psychological treatments to antidepressants., Aims of the Study: To systematically review the evidence for the cost-effectiveness of psychological treatments, psychotherapy and counselling, in comparison with usual care or antidepressant treatment in adult primary care patients with depression., Methods: A computer-assisted search of MEDLINE, EMBASE, CINAHL, PsycINFO, and the Cochrane Library was carried out. Two independent reviewers selected studies for the review, extracted data and assessed the methodological quality of the included studies., Results: Seven studies were included in the review. Forms of psychotherapy that were evaluated were cognitive behavioural therapy, interpersonal psychotherapy and couple therapy. Usual care generally consisted of care as usually provided by the general practitioner. No conclusion can be drawn on the cost-effectiveness of the above mentioned forms of psychotherapy in comparison with usual care or antidepressant treatment. The cost-effectiveness of counselling in comparison with usual care and antidepressant therapy is yet to be established. Meta-analyses showed that psychotherapy was significantly more expensive than usual care, but not significantly more expensive than antidepressant treatment. Counselling was associated with no statistically significant differences in costs and effects in comparison with usual care in the pooled analysis., Discussion: Based on this review, no firm conclusions on the cost-effectiveness of psychotherapy and counselling in primary care can be drawn. Most studies had methodological shortcomings, which limit the generalisibility of the results., Implications for Health Policies: Given the reluctance of patients to use antidepressants and the large economic impact of depression, policy makers have a need for well designed and sufficiently powered economic evaluations of psychological treatments. The available evidence seems to indicate that psychotherapy has more substantial clinical effects than counselling. Therefore, the emphasis should be on economic evaluations of forms of psychotherapy that have proved to be clinically effective., Implications for Further Research: There are indications that the cost-effectiveness of depression treatment on the whole may be improved by incorporating psychological treatments into enhanced care models, tailored to the needs of individual patients and/or by providing them by trained nurses instead of psychologists or psychotherapists. Further research should investigate these patient tailored, stepped care treatment modalities for depression treatment.

Background: Old people (75+) are underrepresented in studies on the prevalence of and risk factors for depression while the number of elderly people suffering from this mood disorder may be considerably higher than previously assumed. The role--if any--of age and gender in 'Geriatric Depression' is still unclear., Methods: In this community-based study, prevalence of depressive symptomatology and risk indicators were assessed in 2850 participants aged 75 years or more. A clinically relevant level of depressive symptoms was defined as a score of > or =16 on the Centre for Epidemiologic Studies Depression scale (CES-D). Demographic data and questions related to physical and psychological health were recorded. Simple and multiple logistic regression techniques were used to determine the risk indicators (Odds Ratios, OR, with 95% confidence intervals, CI) with apparent importance to this population., Results: The prevalence of depressive symptoms was assessed to be 31.1%. This is considerably higher than what has been found in younger elderly samples. The bivariate age effect was OR 1.05 (95% CI=1.03 to 1.07). Controlling for confounding, the effect of gender and age on depressive symptoms disappeared., Conclusions: Depressive symptoms are highly prevalent in the elderly population and increase with age. This increase seems to be attributable to age-related changes in risk factors rather than to ageing itself. With regard to the risk factors found, attention should perhaps be paid to functional disability, loneliness and apprehensiveness for falling since these risk indicators are amenable for improvement.

Background: Earlier reports suggest limited clinical reasoning and substantial uncertainty of GPs in assessing patients suspected of dementia., Objective: To explore the predictors of GPs to decide on the presence and absence of dementia as well as the predictors of diagnostic confidence of GPs., Design: An observational study was set up among 107 patients of 64 GPs. The GPs were instructed to use the Dutch national dementia guideline on consecutive patients newly suspected of dementia and to register their assessment on a detailed form. The predictors of the presence and absence of dementia according to the GPs and their diagnostic confidence were explored by logistic regression analyses., Dependent Variables: (i) presence and absence of dementia according to GPs and (ii) diagnostic confidence., Independent Variables: clinical (cognitive, behavioural, somatic, functional), applications of recommendations, patient related and GP related., Results: Dementia was diagnosed in 67% of the suspected patients. The presence of dementia according to the GPs was positively associated with observed impairment of the higher cognitive functions, absence of depression and female gender of patients. The GPs expressed diagnostic confidence in 58% of the cases. This was positively associated with application of recommendations, ADL dependency, longer duration, informant availability, restless behaviour and a patient's female gender. Use of the Mini Mental Status Examination was not associated with confidence., Conclusions: GPs seem to base the diagnosis of dementia on rational grounds. Application of the dementia guideline's recommendations may contribute to more diagnostic confidence.

Background: The Sense of Competence Questionnaire (SCQ) was originally developed for informal caregivers of patients with diagnosed dementia. In order to study the validity and usefulness of the SCQ when applied to informal caregivers of older adults with dementia symptoms (i.e. cognitive impairment, pre-diagnostic dementia or dementia in its early stages), we investigated the construct validity, feasibility, subscales, homogeneity, and floor and ceiling effects in this new target population., Methods: A psychometric evaluation was performed among 99 informal caregivers. To investigate construct validity, hypotheses were tested, concerning the association between sense of competence and burden, mental quality of life, depressive symptoms, and mastery. To investigate feasibility, response rate and the proportion of missing data were explored for each item. An exploratory principal component analysis was used to investigate whether the SCQ comprises the three subscales established in previous studies. Homogeneity was assessed for each subscale with Cronbach's alpha and item-total correlations. Floor and ceiling effects were explored., Results: Most hypotheses on construct validity were rejected. Only the subscale 'consequences of involvement in care' was found to be partly valid. Feasibility: 93 out of 99 persons completed the SCQ. The proportion of unanswered items per item ranged from 0-3%. Subscales: the SCQ comprises the three expected subscales. Homogeneity: Cronbach's alpha and item-total correlations of the three subscales were satisfactory. A ceiling effect occurred on the subscale 'satisfaction with the care recipient'., Conclusion: The three subscales of the SCQ showed good homogeneity and feasibility, but their validity is insufficient: only the subscale 'consequences of involvement' was found to be partly valid. The two other subscales might not be relevant yet for the new target population, since many of the items on these scales refer to problem behaviour and problematic interactions. Our message to clinicians is not to use these subscales.

Introduction: The efficacy of antidepressants in the treatment of depression has been convincingly demonstrated in randomised trials. However, non-adherence to antidepressant treatment is common., Objective: To evaluate, from a societal perspective, the cost effectiveness of a pharmacy-based intervention to improve adherence to antidepressant therapy in adult patients receiving treatment in primary care., Methods: An economic evaluation was performed alongside a 6-month randomised controlled trial in The Netherlands. Patients who came to 19 pharmacies with a new prescription for a non-tricyclic antidepressant, i.e. those who had not received any prescription for an antidepressant in the past 6 months, were invited to participate. They were then randomly allocated to education and coaching by the pharmacist or to usual care. The coaching programme consisted of three contacts with the pharmacist, with a mean duration of between 13 and 20 minutes, and a take-home video reviewing important facts on depression and antidepressant treatment. The clinical outcome measures were adherence to antidepressant treatment measured using an electronic pill container (eDEM) and improvement in depressive symptoms measured using the Hopkins Symptom Checklist (SCL). Resource use was measured by means of questionnaires. The uncertainty around differences in costs and cost effectiveness between the treatment groups was evaluated using bootstrapping., Results: Seventy patients were randomised to the intervention group and 81 to the usual care group; of these, 40 in the intervention group and 48 in the control group completed all of the follow-up questionnaires. There were no significant differences in adherence, improvements in the SCL depression mean item score and costs over 6 months between the two treatment groups. Mean total costs (2002 values) were 3275 euros in the intervention group and 2961 euros in the control group (mean difference 315 euros; 95% CI -1922, 2416). The incremental cost-effectiveness ratio associated with the pharmacist intervention was 149 euros per 1% improvement in adherence and 2550 euros per point improvement in the SCL depression mean item score. Cost-effectiveness planes and acceptability curves indicated that the pharmacist intervention was not likely to be cost effective compared with usual care., Conclusion: In patients starting treatment with antidepressants, there were no significant differences in adherence, severity of depression, costs and cost effectiveness between patients receiving coaching by a pharmacist and patients receiving usual care after 6 months. Considering the resources needed to implement an intervention like this in clinical practice, based on these results, the continuation of usual care is recommended.

According to professionals, medication nonadherence is often attributed to adverse effects or early remission. There is, however, little evidence to support these attributions. Our aim was to study the predictors of nonadherence in primary care patients with a new antidepressant (AD) prescription. We used a prospective cohort study with 6-month follow-up among 147 primary care patients who were newly prescribed with a nontricyclic AD for depression. They were recruited in 19 community pharmacies in the Netherlands that were linked to 85 general practitioners. An electronic pill container (medication event monitoring system; Aardex Ltd, Untermüli, Switzerland) registered the adherence for 6 months. The predictive values of patient, prescriber, pharmacist, and drug-related characteristics were expressed in univariate and multivariate odds ratios with 95% confidence intervals. Outcome measures showed nonadherence, as expressed in these factors (all dichotomous): (1) incorrect intakes (<80% period coverage); (2) extra pill intakes (>1 per day); (3) drug holidays (>or=1). We found that not only a positive drug attitude, the most important predictor, but also adverse effects, early treatment response, longer onset of depression, and a higher educational level predicted the correct intake of ADs. Extra intakes were predicted by ADs with a shorter half-life and by experience of adverse effects. Drug holidays were predicted by patients with less social support and a negative drug attitude. In conclusion, the predictors of adherence were multifactorial and varied across the 3 adherence types. A positive drug attitude emerged as the most important predictor for correct intakes and drug holidays.

Background: The Montgomery Asberg Depression Rating Scale (MADRS) is a frequently used observer-rated depression scale. In the present study, a telephonic rating was compared with a face-to-face rating in 66 primary care patients with minor or mild-major depression. The aim of the present study was to assess the validity of the administration by telephone. Additional objective was to study the validity of the first item, 'apparent sadness', the only item purely based on observation., Methods: The present study was a validity study. During an in-person interview at the patient's home a trained interviewer administered the MADRS. A few days later the MADRS was administered again, but now by telephone and by a : Mean total score on the in-person administration was 24.0 (SD = 11.1), and on the telephone administration 23.5 (SD = 10.4). The ICC for the full scale was 0.65. Homogeneity analysis showed that the observation item 'apparent sadness' fitted well into the scale., Conclusion: The full MADRS, including the observation item 'apparent sadness', can be administered reliably by telephone.

Background: The objective of this article is to describe the design of an evaluation of the cost-effectiveness of systematic home visits by nurses to frail elderly primary care patients. Pilot objectives were: 1. To determine the feasibility of postal multidimensional frailty screening instruments; 2. to identify the need for home visits to elderly., Methods: Main study: The main study concerns a randomized controlled in primary care practices (PCP) with 18 months follow-up and blinded PCPs. Frail persons aged 75 years or older and living at home but neither terminally ill nor demented from 33 PCPs were eligible. Trained community nurses (1) visit patients at home and assess the care needs with the Resident Assessment Instrument-Home Care, a multidimensional computerized geriatric assessment instrument, enabling direct identification of problem areas; (2) determine the care priorities together with the patient; (3) design and execute interventions according to protocols; (4) and visit patients at least five times during a year in order to execute and monitor the care-plan. Controls receive usual care. Outcome measures are Quality of life, and Quality Adjusted Life Years; time to nursing home admission; mortality; hospital admissions; health care utilization. Pilot 1: Three brief postal multidimensional screening measures to identify frail health among elderly persons were tested on percentage complete item response (selected after a literature search): 1) Vulnerable Elders Screen, 2) Strawbridge's frailty screen, and 3) COOP-WONCA charts. Pilot 2: Three nurses visited elderly frail patients as identified by PCPs in a health center of 5400 patients and used an assessment protocol to identify psychosocial and medical problems. The needs and experiences of all participants were gathered by semi-structured interviews., Discussion: The design holds several unique elements such as early identification of frail persons combined with case-management by nurses. From two pilots we learned that of three potential postal frailty measures, the COOP-WONCA charts were completed best by elderly and that preventive home visits by nurses were positively evaluated to have potential for quality of care improvement.

Minor depression is common in the general population. There is no consensus about prognostic indicators that can identify people at high and low risk of chronicity. We systematically reviewed the available literature on the prognosis of minor depression in the general population and identified five studies. Two of these were considered to be of relatively high methodological quality. There was a wide variety among the studies in the definitions of minor depression, the characteristics of the study population, length of follow-up and type of outcome measure. The results show that the majority of people with minor depression have a favorable prognosis; 46-71.4% achieve remission after a follow-up of 1-6 years. However, 16-62.3% still have a minor depression after 5 months to 1 year of follow-up, suggesting that for many people minor depression is chronic or recurrent; 12.7-27% develop a more severe form of depression; they were diagnosed with dysthymia or major depression after 1-6 years of follow-up. There was inconsistent evidence regarding mortality and functional impairment. No study presented results of prognostic factors, so it remains unclear which people have a more favorable course than others. The results of our review need to be interpreted with caution because of the small number of studies and the large heterogeneity among studies.

Patients' preferences in the treatment of depression are important in clinical practice and in research. Antidepressant medication is often prescribed, but adherence is low. This may be caused by patients preferring psychotherapy, which is often not available in primary care. In randomized clinical trials, patients' preferences may affect the external validity. The aim of this article is to study patients' preferences regarding psychotherapy and antidepressant medication and the impact of these preferences on treatment outcome. A systematic review of the literature was performed. The majority of patients preferred psychotherapy in all available studies. Antidepressants were often regarded as addictive and psychotherapy was assumed to solve the cause of depression. Discussing and supporting preferences as part of a quality improvement program of depression care, resulted in more patients receiving the treatment that was most suitable to them. In two patient-preference trials, preferences did not influence treatment outcome. It can be concluded that a substantial percentage of well-informed patients prefer psychotherapy. Patients with strong preferences, mostly for psychotherapy, are likely not to enter antidepressant treatment or randomized clinical trials if their preferences are not supported.

Background: Community pharmacists strive to deliver pharmaceutical care to patients. At the moment, coaching of depressive primary care patients on taking their antidepressants (ADs) is not yet part of their standard care package., Aims: To investigate the effects of coaching by community pharmacists on psychological symptoms., Method: A randomised controlled trial with a 6-month follow-up., Outcomes: psychological symptoms with the Hopkins Symptom Checklist (SCL). Intention-to-treat (ITT) was performed with (1) last observation carried forward and (2) with group mean imputation (GMI)., Results: Analyses with LOCF and GMI resulted in different findings. The LOCF method revealed that at the 6-month follow-up, the intervention patients were less depressed and less anxious than the controls. The intervention was particularly effective in patients with lower levels of education who received pharmacist's coaching. However, ITT with the GMI method showed no differences in psychological symptoms. Differences between LOCF and GMI were explained by the selective attrition in the intervention arm (attrition intervention patients had lower initial SCL-item scores on depression and anxiety than the completers) and by the higher attrition rate in controls., Conclusions: Our study indicates that the interpretation of the effects of an intervention on psychological symptoms can differ substantially by the way missing values are imputed. If both LOCF and GMI produce significant differences, efficacy can be concluded. If not, the effects based on ITT analyses with LOCF are based on artefacts. We recommend that positive intervention effects should only be reported when findings with LOCF and GMI are in accordance.

General practitioners (GPs) are recommended to use DSM-IV criteria to diagnose major depression in daily clinical practice. This implies the assessment of nine depressive symptoms and four additional criteria. A short structured interview has been developed to assess these symptoms and criteria, and a study was carried out to investigate the reliability and validity with which GPs can assess these symptoms and criteria and the DSM-IV diagnosis of major depression. In 14 general practices, 52 patients with symptoms of distress and depression were interviewed twice by their GP, with an interval of one to four days. Furthermore, the patients filled out three depression questionnaires. The reproducibility of eight symptoms and three additional criteria was moderate to good (kappa >0.40). The reproducibility of the depressive symptom count, that is necessary to arrive at a diagnosis of major depression, was such that in 75 percent of the patients the test-retest difference did not exceed one symptom. The reproducibility of the diagnosis of major depression was good (kappa 0.63). The validity of the diagnosis of major depression assessed by the GPs, as compared to results of the self-report depression questionnaires, was satisfactory (r 0.35-0.61). Diagnosing major depression in patients with depressive symptomatology just above or below the threshold of major depression warrants a certain amount of caution in general practice.
