Determinants and consequences of polypharmacy in patients with a depressive disorder in later life.

OBJECTIVES: Polypharmacy and late-life depression often congregate in the geriatric population. The primary objective is to identify determinants of polypharmacy in patients with depression, and second to examine polypharmacy in relation to various clinical phenotypes of depression and its course. METHODS: A longitudinal observational study using data of the Netherlands Study of Depression in Older persons (NESDO) including 375 patients with depression ≥ 60 years and 132 non-depressed comparisons. Linear and logistic regression were used to analyze both polypharmacy (dichotomous: ≥5 medications) and number of prescribed drugs (continuous) in relation to depression, various clinical phenotypes, and depression course. RESULTS: Polypharmacy was more prevalent among patients with depression (46.9%) versus non-depressed comparisons (19.7%). A lower level of education, lower cognitive functioning, and more chronic diseases were independently associated with polypharmacy. Adjusted for these determinants, polypharmacy was associated with a higher level of motivational problems, anxiety, pain, and an earlier age of onset. A higher number of drugs was associated with a worse course of late-life depression (OR = 1.24 [95% CI: 1.03-1.49], p = 0.022). CONCLUSION: Older patients with depression have a huge risk of polypharmacy, in particular among those with an early onset depression. As an independent risk factor for chronic depression, polypharmacy needs to be identified and managed appropriately. Findings suggest that depression moderates polypharmacy through shared risk factors, including motivational problems, anxiety, and pain. The complex interaction with somatic health burden requires physicians to prescribe medications with care.

Fatigue among Long-Term Breast Cancer Survivors: A Controlled Cross-Sectional Study.

BACKGROUND: Fatigue is the most common and persistent symptom among women in the first five years after a breast cancer diagnosis. However, long-term prevalence of fatigue, among breast cancer survivors, needs further investigation. AIM: To compare fatigue experienced by long-term breast cancer survivors with that in a reference population and to evaluate the determinants of that fatigue. DESIGN AND SETTING: A cross-sectional cohort study of 350 breast cancer survivors ≥5 years after diagnosis and a reference population of 350 women matched by age and general practitioner. METHOD: Fatigue was measured using the Multidimensional Fatigue Inventory (MFI-20), and a sum score of >60 (multidimensional fatigue) was the primary outcome. Logistic regression was applied to compare the prevalence of multidimensional fatigue between the survivor and reference populations, adjusted for body mass index (BMI) and for cardiovascular and psychological variables. Odds ratios (ORs) and 95% confidence intervals (95%CIs) were estimated. Logistic regression was applied to evaluate the determinants of multidimensional fatigue among the survivors. RESULTS: Breast cancer survivors (median 10 years after diagnosis), more often experienced multidimensional fatigue than the reference population (26.6% versus 15.4%; OR, 2.0 [95%CI, 1.4-2.9]), even after adjusting for confounders. The odds of multidimensional fatigue were also higher among survivors with symptoms of depression (32.2% versus 2.7%; OR, 17.0 [95%CI, 7.1-40.5]) or anxiety (41.9% versus 10.1%; OR, 6.4 [95%CI, 3.6-11.4]). CONCLUSION: One in four breast cancer survivors experience multidimensional fatigue and fatigue occurs more frequently than in women of the same age and general practitioner. This fatigue appears to be associated with symptoms of depression and anxiety.

Developing a clinical prediction rule for repeated consultations with functional somatic symptoms in primary care: a cohort study.

OBJECTIVES: Patients who present in primary care with chronic functional somatic symptoms (FSS) have reduced quality of life and increased health care costs. Recognising these early is a challenge. The aim is to develop and internally validate a clinical prediction rule for repeated consultations with FSS. DESIGN AND SETTING: Records from the longitudinal population-based ('Lifelines') cohort study were linked to electronic health records from general practitioners (GPs). PARTICIPANTS: We included patients consulting a GP with FSS within 1 year after baseline assessment in the Lifelines cohort. OUTCOME MEASURES: The outcome is repeated consultations with FSS, defined as ≥3 extra consultations for FSS within 1 year after the first consultation. Multivariable logistic regression, with bootstrapping for internal validation, was used to develop a risk prediction model from 14 literature-based predictors. Model discrimination, calibration and diagnostic accuracy were assessed. RESULTS: 18 810 participants were identified by database linkage, of whom 2650 consulted a GP with FSS and 297 (11%) had ≥3 extra consultations. In the final multivariable model, older age, female sex, lack of healthy activity, presence of generalised anxiety disorder and higher number of GP consultations in the last year predicted repeated consultations. Discrimination after internal validation was 0.64 with a calibration slope of 0.95. The positive predictive value of patients with high scores on the model was 0.37 (0.29-0.47). CONCLUSIONS: Several theoretically suggested predisposing and precipitating predictors, including neuroticism and stressful life events, surprisingly failed to contribute to our final model. Moreover, this model mostly included general predictors of increased risk of repeated consultations among patients with FSS. The model discrimination and positive predictive values were insufficient and preclude clinical implementation.

Trajectories and determinants of functional limitations in late-life depression: A 2-year prospective cohort study.

BACKGROUND: In mental health research, functional recovery is increasingly valued as an important outcome in addition to symptomatic remission. METHODS: Course types of functional limitations among depressed older patients and its relation with symptomatic remission were explored in a naturalistic cohort study (Netherlands Study of Depression in Older persons). 378 depressed older patients (≥60 years) and 132 non-depressed persons were included. Depressive disorders were assessed with Composite International Diagnostic Interview at baseline and two-year follow-up. Functional limitations were assessed every 6 months with the World Health Organization Disability Assessment II. RESULTS: Depressed patients had more functional limitations compared to their non-depressed counterparts. Growth Mixture Modeling among depressed patients identified two trajectories of functional limitations, both starting at a high disability level. The largest subgroup (81.2%) was characterized by a course of high disability levels over time. The smaller subgroup (18.8%) had an improving course (functional recovery). After two years, the main predictor of functional recovery was the remission of depression. Among symptomatic remitted patients, female sex, higher level of education, higher gait speed, and less severe depression were associated with no functional recovery. Non-remitted patients without functional recovery were characterized by the presence of more chronic somatic diseases, a lower sense of mastery, and a higher level of anxiety. CONCLUSIONS: 1 in 5 depressed older patients have a course with functional recovery. Combining functional and symptomatic recovery points to a subgroup of older patients that might profit from more rigorous psychiatric treatment targeted at psychiatric comorbidity and a group of frail depressed older patients that might profit from integrated geriatric rehabilitation.

What proportion of initially prescribed antidepressants is still being prescribed chronically after 5 years in general practice? A longitudinal cohort analysis.

OBJECTIVES: Antidepressant prescribing almost doubled in the Netherlands between 1996 and 2012, which could be accounted for by longer continuation after the first prescription. This might be problematic given a growing concern of large-scale antidepressant dependence. We aimed to assess the extent and determinants of chronic antidepressant prescribing among patient aged 18 years and older. We hypothesise a relatively large prevalence of chronic (>2 years) prescription. DESIGN: A longitudinal observational study based on routinely registered prescription data from general practice. SETTING: 189 general practices in the Netherlands. PARTICIPANTS: 326 025 patients with valid prescription data for all 5 years of the study. OUTCOME MEASURES: Primary outcome measure: the number of patients (N) receiving at least four antidepressant prescriptions in 2011, as well as during each of the four subsequent years. Secondary outcome measure: the above, but specified for selective serotonin reuptake inhibitors and for tricyclic antidepressants. RESULTS: Antidepressants were prescribed to almost 7% of our 326 025 participants each year. They were prescribed for depression (38%), anxiety (17%), other psychological disorders (20%) and non-psychological indications (25%). Antidepressants were prescribed in all 5 years to the 42% of the population who had at least four prescriptions dispensed in 2011. Chronic prescribing was higher among women than men, for those aged 45-64 years than for those aged >65 years and for those treated for depression or anxiety than for non-psychological indications (eg, neuropathic pain). Chronic prescribing also varied markedly among general practices. CONCLUSION: Chronic antidepressant use is common for depression and for anxiety and non-psychological diagnoses. Once antidepressants have been prescribed, general practitioners and other prescribers should be aware of the risks associated with long-term use and should provide annual monitoring of the continued need for therapy.

Non-adherence to antidepressants among older patients with depression: a longitudinal cohort study in primary care.

Background: Depression is common among older adults and is typically treated with antidepressants. Objective: To determine the non-adherence rates to antidepressants among older adults in primary care, based on non-initiation, suboptimal implementation or non-persistence. Methods: We selected all patients aged ≥60 years and diagnosed with depression in 2012, from the Netherlands Institute for Health Services Research (NIVEL) Primary Care Database. Non-initiation was defined as no dispensing within 14 days of the first prescription; suboptimal implementation, as fewer than 80% of the days covered by dispensed dosages; and non-persistence, as discontinuation within 294 days after first dispense. First, we determined the antidepressant non-initiation, suboptimal implementation and non-persistence rates. Second, we examined whether comorbidity and chronic drug use were associated with non-adherence by mixed-effects logistic regression (non-initiation or suboptimal implementation as dependent variables) and a clustered Cox regression (time to non-persistence). Results: Non-initiation, suboptimal implementation and non-persistence rates were 13.5%, 15.2% and 37.1%, respectively. As the number of chronically used drugs increased, the odds of suboptimal implementation (odds ratio, 0.89; 95% confidence interval, 0.83-0.95) and of non-persistence (hazard ratio, 0.87; 95% confidence interval, 0.82-0.92) reduced. Conclusions: Non-adherence to antidepressants is high among older patients with depression in primary care settings. Adherence is better when patients are accustomed to taking larger numbers of prescribed drugs, but this only provides partial explanation of the variance. GPs should be aware of the high rates of non-adherence. Emphasizing the importance of adhering to the optimal length of antidepressant therapy might be prudent first steps to improving adherence.

Non-adherence to cardiovascular drugs in older patients with depression: A population-based cohort study.

BACKGROUND: Depression is common among patients with cardiovascular disease and has been associated with both drug non-adherence and increased mortality. Non-adherence can occur because of non-initiation, suboptimal implementation, or non-persistence. We aimed to determine if depression increased the risk of any of these components of non-adherence among older patients prescribed cardiovascular drugs in primary care. METHODS: A longitudinal analysis of routine primary care data from the Nivel Primary Care Database was performed using data for 2011-2013. A total of 1512 patients aged ≥60 years diagnosed with depression in 2012 were compared with age- and sex-matched groups with either other psychological diagnoses (N = 1457) or mentally healthy controls (N = 1508), resulting in the inclusion of 4477 patients. Non-adherence was classified as non-initiation, suboptimal implementation, or non-persistence. Regression analyses were performed to determine the association between mental health status and non-initiation, suboptimal implementation, and non-persistence. RESULTS: Mixed-effects logistic regression analyses showed increased odds for suboptimal implementation of beta-blockers among depressed patients (2.18; 95% CI 1.29-3.69). For non-persistence, a clustered Cox regression analysis demonstrated that, compared with controls, there was an increased hazard ratio for depressed patients to discontinue beta-blockers (2.31; 95% CI 1.58-3.37) and calcium antagonists (1.74; 95% CI 1.23-2.46). CONCLUSIONS: It is likely that older patients in primary care diagnosed with depression are at increased risk of non-persistence with cardiovascular drug therapy. Because non-adherence is associated with increased cardiovascular mortality, it is important that physicians ensure that older depressed patients persevere with therapy.

Withdrawal of unnecessary antidepressant medication: a randomised controlled trial in primary care.

BACKGROUND: Antidepressant use has increased exponentially in recent decades, mostly due to long continuation. AIM: To assess the effectiveness of a tailored recommendation to withdraw antidepressant treatment. DESIGN & SETTING: Randomised controlled trial in primary care (PANDA study) in the Netherlands. METHOD: Long-term antidepressant users (≥9 months) were selected from GPs prescription databases. Patients were diagnosed with the Composite International Diagnostic Interview (CIDI). Long-term users without indication for maintenance treatment (overtreatment) were selected. The intervention consisted of disclosure of the current psychiatric diagnosis combined with a tailored treatment recommendation. Patients were followed for 12 months. RESULTS: The study included 146 participants from 45 family practices. Of the 70 patients in the intervention group, 34 (49%) did not comply with the advice to stop their antidepressant medication. Of the 36 (51%) patients who agreed to try, only 4 (6%) succeeded. These figures were consistent with the control group, where 6 (8%) of the 76 patients discontinued antidepressant use successfully. Patients who were recommended to discontinue their antidepressant medication reported a higher relapse rate than the control group (26% versus 13%, P = 0.05). CONCLUSION: Changing inappropriate long-term antidepressant use is difficult.

The effectiveness of shared decision-making followed by positive reinforcement on physical disability in the long-term follow-up of patients with nonspecific low back pain in primary care: a clustered randomised controlled trial.

BACKGROUND: Although the recovery of patients suffering from low back pain is highly context dependent, patient preferences about treatment options are seldom incorporated into the therapeutic plan. Shared decision-making (SDM) offers a tool to overcome this deficiency. The reinforcement by the general practitioner (GP) of a 'shared' chosen therapy might increase patients' expectations of favourable outcomes and thus contribute to recovery. METHODS: In the Netherlands, a clustered randomised controlled trial was performed to assess the effectiveness of shared decision-making followed by positive reinforcement of the chosen therapy (SDM&PR) on patient-related clinical outcomes. Overall, 68 GPs included 226 patients visiting their GP for a new episode of non-chronic low back pain. GPs in the intervention group were trained in implementing SDM&PR using a structured training programme with a focus on patient preferences in reaching treatment decisions. GPs in the control group provided care as usual. The primary outcome was the change in physical disability measured with the Roland-Morris disability questionnaire (RMD) during the six-month follow-up after the first consultation. Physical disability (RMD), pain, adequate relief, absenteeism and healthcare consumption at 2, 6, 12 and 26 weeks were secondary outcomes. A multivariate analysis with a mixed model was used to estimate the differences in outcomes. RESULTS: Of the patients in the intervention and the control groups, 66 and 62%, respectively, completed the follow-up. Most patients (77%) recovered to no functional restrictions due to back pain within 26 weeks. No significant differences in the mean scores for any outcome were observed between intervention patients and controls during the follow-up, and in multivariate analysis, there was no significant difference in the main outcome during the six-month follow-up. Patients in the intervention group reported more involvement in decision-making. CONCLUSION: This study did not detect any improvement in clinical outcome or in health care consumption of patients with non-chronic low back pain after the training of GPs in SDM&PR. The implementation of SDM merely introduces task-oriented communication. The training of the GPs may have been more effective if it had focused more on patient-oriented communication techniques and on stressing the expectation of favourable outcomes. TRIAL REGISTRATION: The Netherlands National Trial Register (NTR) number: NTR1960. The trial was registered in the NTR on August 20, 2009.

Symptomatic and functional recovery in depression in later life.

OBJECTIVES: Functional limitations give an indication of the total impact of diseases, such as depression, on individuals health and recovery. This study examines the change in several domains of functioning over 2 years in older persons depressed at baseline (non-remitted group and remitted group after 2 years) and in a non-depressed comparison group. METHODS: Data were used from a cohort study (Netherlands Study of Depression in Older persons [NESDO]) consisting of depressed older persons ≥ 60 years (N = 378) and a non-depressed comparison group (N = 132) with 2 years of follow-up (attrition rate 24%). Functional limitations (outcome) were assessed with the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) questionnaire every 6 months. Total scores and domain scores were used. Depression was classified according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria at baseline and at 2-year follow-up. Severity of depression (predictor) was assessed with the Inventory of Depressive Symptomatology (IDS) at 6-month intervals. RESULTS: Linear mixed models showed that the level of functional limitations differed between the three groups during 2 years of follow-up. The non-remitted group had the highest level of functional limitations during 2 years, followed by the remitted group. Stable low levels of functional limitations were found for the non-depressed group. Remission from depression was accompanied by improvements in functioning, however, compared to the non-depressed comparison group significant functional limitations remained. Higher severity of depression appeared as risk factor for a declining course of functioning, especially the social aspects of functioning. METHODOLOGICAL CONSIDERATIONS: Participants that were more severely depressed and more functionally impaired at baseline had higher attrition rates than the participants that were included in the analytical sample. CONCLUSION: This study showed that depression in later life has long-term debilitating effects on functioning, enduring even after remission from depression. This implies that depression treatment in later life should aim broader than just symptomatic recovery, but also include functional recovery.

Antidepressant prescriptions and mental health nurses: an observational study in Dutch general practice from 2011 to 2015.

PURPOSE: The purpose of this study was to investigate developments in antidepressant prescriptions by Dutch general practitioners, alongside the national introduction of mental health nurses. Antidepressant prescriptions are very common in general practice, but are often not in line with recommendations. The recent introduction of mental health nurses may have decreased antidepressant prescriptions, as general practitioners (GPs) have greater potential to offer psychological treatment as a first choice option instead of medication. MATERIAL AND METHODS: Anonymised data from the medical records of general practices participating in the NIVEL Primary Care Database in 2011-2015 were analysed in an observational study. We used multilevel logistic regression analyses to determine whether total antidepressant prescriptions and antidepressants prescribed within one week of diagnosing anxiety or depression decreased in the period 2011-2015. We analysed whether changes in antidepressant prescriptions were associated with the employment or consultation of mental health nurses. RESULTS: Antidepressants were prescribed in 30.3% of all anxiety or depression episodes; about half were prescribed within the first week. Antidepressants prescriptions for anxiety or depression increased slightly in the period 2011-2015. The employment of mental health nurses was not associated with a decreased number of prescriptions of antidepressants. Patients who had at least one mental health nurse consultation had fewer immediate prescriptions of antidepressants, but not fewer antidepressants in general. CONCLUSIONS: Antidepressant prescriptions are still common in general practice. So far, the introduction of mental health nurses has not decreased antidepressant prescriptions, but it may have a postponing effect.

Exploring the feasibility of new Dutch mental health policy within a large primary health care centre: a case study.

Background: A reform of Dutch mental health care aimed to substitute care from specialized care to general practice. Since 1 January 2014, Dutch general practitioners (GPs) are no longer allowed to refer patients without a psychiatric disorder to mental health care. Patients with non-complex psychological problems should be treated within general practice. Objective: To explore the feasibility of the Dutch mental health policy. Methods: We conducted an observational case study in a primary health care centre in 2014. The health care centre was a convenience sample; the participating GPs reorganized mental health care in line with the upcoming policy, and invited the researchers to monitor their referrals. We assessed how many patients with mental health problems (n = 408) were allocated to policy-concordant treatment. Additionally, 137 patients (33%) completed a follow up assessment on mental health problems 3 months after baseline. Results: The majority of the patients were allocated to treatment in line with the policy. Almost half of the patients (42%) were treated in a setting that was exactly policy-concordant, while the other half (47%) was treated in a setting that was even less specialized than was allowed. In general, patients showed improvement after 3 months, regardless of (non) policy-concordant treatment. Attrition rate after 3 months was high, probably due to the practical study design. Conclusion: There is potential for substitution of mental health care. Since the studied health care centre was specialized in mental health care, further research should explore if similar results can be found in other general practices.

Non-pharmacological treatment for depressed older patients in primary care: A systematic review and meta-analysis.

BACKGROUND: Late-life depression is most often treated in primary care, and it usually coincides with chronic somatic diseases. Given that antidepressants contribute to polypharmacy in these patients, and potentially to interactions with other drugs, non-pharmacological treatments are essential. In this systematic review and meta-analysis, we aimed to present an overview of the non-pharmacological treatments available in primary care for late-life depression. METHOD: The databases of PubMed, PsychINFO, and the Cochrane Central Register of Controlled Trials were systematically searched in January 2017 with combinations of MeSH-terms and free text words for "general practice," "older adults," "depression," and "non-pharmacological treatment". All studies with empirical data concerning adults aged 60 years or older were included, and the results were stratified by primary care, and community setting. We narratively reviewed the results and performed a meta-analysis on cognitive behavioral therapy in the primary care setting. RESULTS: We included 11 studies conducted in primary care, which covered the following five treatment modalities: cognitive behavioral therapy, exercise, problem-solving therapy, behavioral activation, and bright-light therapy. Overall, the meta-analysis showed a small effect for cognitive behavioral therapy, with one study also showing that bright-light therapy was effective. Another 18 studies, which evaluated potential non-pharmacological interventions in the community suitable for implementation, indicated that bibliotherapy, life-review, problem-solving therapy, and cognitive behavioral therapy were effective at short-term follow-up. DISCUSSION: We conclude that the effects of several treatments are promising, but need to be replicated before they can be implemented more widely in primary care. Although more treatment modalities were effective in a community setting, more research is needed to investigate whether these treatments are also applicable in primary care. TRIAL REGISTRATION: PROSPERO CRD42016038442.

Late-life depression and the association with multimorbidity and polypharmacy: a cross-sectional study.

Background: Late-life depression often coincides with chronic somatic diseases and, consequently, with polypharmacy, which may complicate medical treatment. Objective: To determine the associations between patients diagnosed with late-life depression in primary care and multimorbidity and polypharmacy. Methods: This cross-sectional observational study was performed using 2012 primary care data. Depressed patients aged ≥60 years were compared to age and gender matched patients diagnosed with other psychological diagnoses and mentally healthy controls. Morbidity and prescription data were combined, and regression analyses were performed for the associations between depression and chronic disease and chronic drug use. Results: We included 4477 patients; 1512 had a record of depression, 1457 of other mental health or psychological diagnoses and 1508 were controls. Depressed patients had a 16% [Prevalence Ratio (PR) 1.16; 95% confidence interval (95% CI) 10%-24%] higher rate of chronic somatic disease and higher odds for multimorbidity (OR 1.55; 95% CI 1.33-1.81) compared with controls. No differences existed between depressed patients and patients with other psychological diagnoses. Compared with controls, depressed patients had a 46% (95% CI 39-53%) higher rate of chronic drug use and higher odds for polypharmacy (OR 2.89; 95% CI 2.41-3.47). Depressed patients also had higher rates of chronic drug use and higher odds for polypharmacy compared with patients with other psychological diagnoses (PR 1.26; OR 1.75; both P < 0.001). Conclusions: Late-life depression in primary care patients is associated with more chronic drug use, even beyond the increased rates of comorbid somatic diseases. General practitioners should consider medication reviews to prevent unnecessary drug-related problems in these patients.

Potential for substitution of mental health care towards family practices: an observational study.

BACKGROUND: Substitution is the shift of care from specialized health care to less expensive and more accessible primary health care. It seems promising for restraining rising mental health care costs. The goal of this study was to investigate a potential for substitution of patients with psychological or social problems, but without severe psychiatric disorders, from Dutch specialized mental health care to primary care, especially family practices. METHODS: We extracted anonymized data from two national databases representing primary and specialized care in 2012. We calculated the number of patients with and without psychiatric disorder per 1,000 citizens in three major settings: family practices, primary care psychologists, and specialized care. Family physicians recorded psychopathology using the International Classification of Primary Care, while psychologists and specialists used the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition. RESULTS: Considerable numbers of patients without a diagnosed DSM-IV psychiatric disorder were treated by primary care psychologists (32.8%) or in specialized care (20.8%). Over half of the patients referred by family physicians to mental health care did not have a psychiatric disorder. CONCLUSION: A recent reform of Dutch mental health care, including new referral criteria, will likely increase the number of patients with psychological or social problems that family physicians have to treat or support. Enabling and improving diagnostic assessment and treatment in family practices seems essential for substitution of mental health care.

Applying Computerized Adaptive Testing to the Four-Dimensional Symptom Questionnaire (4DSQ): A Simulation Study.

BACKGROUND: Efficient screening questionnaires are useful in general practice. Computerized adaptive testing (CAT) is a method to improve the efficiency of questionnaires, as only the items that are particularly informative for a certain responder are dynamically selected. OBJECTIVE: The objective of this study was to test whether CAT could improve the efficiency of the Four-Dimensional Symptom Questionnaire (4DSQ), a frequently used self-report questionnaire designed to assess common psychosocial problems in general practice. METHODS: A simulation study was conducted using a sample of Dutch patients visiting a general practitioner (GP) with psychological problems (n=379). Responders completed a paper-and-pencil version of the 50-item 4DSQ and a psychometric evaluation was performed to check if the data agreed with item response theory (IRT) assumptions. Next, a CAT simulation was performed for each of the four 4DSQ scales (distress, depression, anxiety, and somatization), based on the given responses as if they had been collected through CAT. The following two stopping rules were applied for the administration of items: (1) stop if measurement precision is below a predefined level, or (2) stop if more than half of the items of the subscale are administered. RESULTS: In general, the items of each of the four scales agreed with IRT assumptions. Application of the first stopping rule reduced the length of the questionnaire by 38% (from 50 to 31 items on average). When the second stopping rule was also applied, the total number of items could be reduced by 56% (from 50 to 22 items on average). CONCLUSIONS: CAT seems useful for improving the efficiency of the 4DSQ by 56% without losing a considerable amount of measurement precision. The CAT version of the 4DSQ may be useful as part of an online assessment to investigate the severity of mental health problems of patients visiting a GP. This simulation study is the first step needed for the development a CAT version of the 4DSQ. A CAT version of the 4DSQ could be of high value for Dutch GPs since increasing numbers of patients with mental health problems are visiting the general practice. In further research, the results of a real-time CAT should be compared with the results of the administration of the full scale.

Patients' readiness to receive psychosocial care during nurse-led routine diabetes consultations in primary care: A mixed methods study.

BACKGROUND: Patients with type 2 diabetes mellitus face several emotional and social consequences of their chronic illness in their everyday life. Symptoms of distress and depression are prevalent. For providing psychosocial self-management support, nurses in primary care were trained to identify patients with psychosocial problems during routine medically-shaped diabetes consultations. However, detection rates appeared to be strikingly low. OBJECTIVES: Our study aimed to examine patients' readiness to discuss psychosocial problems with nurses during diabetes consultations. DESIGN: A mixed methods design was used in which qualitative data collection was followed up by quantitative data collection. SETTING: Diabetes care in a regional group of family practices in the south of the Netherlands. PARTICIPANTS: Type 2 diabetes patients with psychosocial problems, determined by a self-administered questionnaire. METHODS: First, in-depth interviews (n=12) were conducted about patients' experiences with routine diabetes consultations and their perspective on a biopsychosocial care approach. Based on a qualitative content analysis, a structured questionnaire was designed to further explore the findings among a larger group of patients. This questionnaire was completed by 205 patients. The questionnaire included 14 items measuring patients' agreement with statements about diabetes care and the role of the nurse to focus on patients' emotional and social functioning. RESULTS: The interviews showed that patients view a diabetes consultation primarily as a biomedical check-up, and do not perceive discussion of psychosocial well-being as an integral part of diabetes management. More than 90% of the sample showed a positive attitude towards current diabetes consultations. Patients' intentions and perceived needs regarding a biopsychosocial care approach of the nurse were variable. Younger patients seemed more open to discussing psychosocial problems with the nurse than patients over 65. Patients' openness to discussing psychosocial problems was not significantly (p<0.05) associated with the nurses being trained in the biopsychosocial self-management approach. CONCLUSION: Patients see primary care nurses primarily as specialists regarding the biomedical management of diabetes. Although patients seemed to support the ideal of integrated care, they did not expect a discussion about psychosocial problems in diabetes consultations. The incorporation of systematic detection of patients with psychosocial problems in diabetes care requires endeavours to make patients acquainted with the new role of the nurse.

Long-term antidepressant use: a qualitative study on perspectives of patients and GPs in primary care.

BACKGROUND: Antidepressant use is often prolonged in patients with anxiety and/or depressive disorder(s) compared with recommendations in treatment guidelines to discontinue after sustained remission. AIM: To unravel the motivations of patients and GPs causing long-term antidepressant use and to gain insight into possibilities to prevent unnecessary long-term use. DESIGN AND SETTING: Qualitative study using semi-structured, in-depth interviews with patients and GPs in the Netherlands. METHOD: Patients with anxiety and/or depressive disorder(s) (n = 38) and GPs (n = 26) were interviewed. Innovatively, the interplay between patients and their GPs was also investigated by means of patient-GP dyads (n = 20). RESULTS: The motives and barriers of patients and GPs to continue or discontinue antidepressants were related to the availability of supportive guidance during discontinuation, the personal circumstances of the patient, and considerations of the patient or GP. Importantly, dyads indicated a large variation in policies of general practices around long-term use and continuation or discontinuation of antidepressants. Dyads further indicated that patients and GPs seemed unaware of each other's (mismatching) expectations regarding responsibility to initiate discussing continuation or discontinuation. CONCLUSION: Although motives and barriers to antidepressant continuation or discontinuation were related to the same themes for patients and GPs, dyads indicated discrepancies between them. Discussion between patients and GPs about antidepressant use and continuation or discontinuation may help clarify mutual expectations and opinions. Agreements between a patient and their GP can be included in a patient-tailored treatment plan.

Consultations in general practices with and without mental health nurses: an observational study from 2010 to 2014.

OBJECTIVES: To investigate care for patients with psychological or social problems provided by mental health nurses (MHNs), and by general practitioners (GPs) with and without MHNs. DESIGN: An observational study with consultations recorded by GPs and MHNs. SETTING: Data were routinely recorded in 161-338 Dutch general practices between 2010 and 2014. PARTICIPANTS: All patients registered at participating general practices were included: 624 477 patients in 2010 to 1 392 187 patients in 2014. OUTCOME MEASURES: We used logistic and Poisson multilevel regression models to test whether GPs recorded more patients with at least one consultation for psychological or social problems and to analyse the number of consultations over a 5-year time period. We examined the additional effect of an MHN in a practice, and tested which patient characteristics predicted transferral from GPs to MHNs. RESULTS: Increasing numbers of patients with psychological or social problems visit general practices. Increasing numbers of GPs collaborate with an MHN. GPs working in practices with an MHN record as many consultations per patient as GPs without an MHN, but they record slightly more patients with psychological or social problems (OR=1.05; 95% CI 1.02 to 1.08). MHNs most often treat adult female patients with common psychological symptoms such as depressive feelings. CONCLUSIONS: MHNs do not seem to replace GP care, but mainly provide additional long consultations. Future research should study to what extent collaboration with an MHN prevents patients from needing specialised mental healthcare.

Use of general practice services 5 years after an episode of mental illness: case-control study using electronic records.

BACKGROUND: Depression, anxiety, and emotional distress occur frequently and are usually treated in general practice. Little has been reported about the long-term course of these conditions and the long-term use of medical services. AIM: To follow up patients with depression, anxiety, and emotional distress in general practice for 5 years and examine the length and number of index episodes, prescribing behaviour, and the use of services in general practice. DESIGN AND SETTING: A case-control study using data from electronic medical records. METHOD: Three cohorts of patients with depression (n = 453), anxiety (n = 442), and emotional distress (n = 185) were compared against a cohort of control patients (n = 4156) during a 5-year follow-up from 2007 to 2011. The occurrence or recurrence of the index disorders, other psychological disorders or medical conditions, the numbers of prescriptions, and the number of contacts with the general practice were all examined. RESULTS: Patients in the depression group had 1.1 followup episodes of depression, those in the anxiety group had 0.9 follow-up episodes of anxiety, and those in the emotional distress group had 0.5 follow-up episodes of emotional distress during the 5 years. All three groups had more consultations (for both psychological and somatic reasons) during each of the follow-up years than control patients. Furthermore, the groups with mental health disorders were given more prescriptions for psychopharmacological treatment. CONCLUSION: Five years after the index episode in 2007, patients with an episode of depression, anxiety, or emotional distress are still not comparable with control patients, in terms of the prevalence of mental health conditions, the number of prescriptions, and healthcare use.
