Stepped care for depression is easy to recommend, but harder to implement: results of an explorative study within primary care in the Netherlands

BACKGROUND: Depression is a common mental disorder with a high burden of disease which is mainly treated in primary care. It is unclear to what extent stepped care principles are applied in routine primary care. The first aim of this explorative study was to examine the gap between routine primary depression care and optimal care, as formulated in the depression guidelines. The second aim was to explore the facilitators and barriers that affect the provision of optimal care. METHODS: Optimal care was operationalised by indicators covering the entire continuum of depression care: from prevention to chronic depression. Routine care was investigated by interviewing general practitioners (GPs) individually and together with other mental health care providers about the depression care they delivered collaboratively. Qualitative analysis of transcripts was performed using thematic coding. Additionally, the GPs completed a self-report questionnaire. RESULTS: Six GPs and 22 other (mostly primary) mental health care providers participated. The GPs and their primary care colleagues embraced a general stepped care approach. They offered psycho-education and counselling to mildly depressed patients. When the treatment effects were not satisfactory or patients were more severely depressed, the GPs offered, or referred to, psychotherapy or pharmacotherapy. Patients with a complex and severe depressive disorder were directly referred to specialised mental health care. However, GPs relied on their clinical judgment and rarely used instruments to assess and monitor the severity of depressive symptoms. Structured, evidence based interventions such as self-management and e-health were rarely offered to patients with depressive symptoms. Specific psychological interventions for relapse prevention or for chronically depressed patients were not available. A wide range of influencing factors for the provision of optimal depression care were put forward. Close collaboration with other mental health care professionals was considered an important factor for improvement by nearly all GPs. CONCLUSIONS: The management of depression in primary care seems in line with stepped care principles, although it can be improved by applying more elements of a stepped care approach. Collaboration between GPs and mental health care providers in primary care and secondary care should be enhanced

Cerebrovascular risk factors and subsequent depression in older general practice patients

Background: This general practice-based case-control study tested the association between cerebrovascular risk factors (CVRFs) and the development of later-life depression by focusing on the impact of exposure duration to CVRFs and the modifying influence of age at depression onset. Methods: Cases were 286 patients aged >/=50 years with a first diagnosis of depression at age >/=50 years. Nondepressed controls (N=832) were individually matched for age, gender and practice. CVRF diagnoses (hypertension, diabetes mellitus, cardiovascular conditions) prior to depression were determined. Analyses controlled for education, somatic and nondepressive psychiatric disease. Results: No CVRF variable examined was significantly associated with subsequent depression in the total sample. An unexpected impact of age at onset of depression was observed: the odds ratio associated with having any CVRF was smaller for patients with age at onset >/=70 years than for patients with onset between ages 50-59 years (p=.002) and 60-69 years (p=.067). Subsequent analyses excluding patients with onset at age >/=70 years revealed that CVRF variables, including long-term exposure to CVRFs, significantly increased the odds of subsequent depression with onset between ages 50 and 69 years. Limitations: Reliance on GPs' records of morbidity may have resulted in bias towards underestimation in patients with depression onset at age >/=70 years. Conclusions: Our findings suggest that CVRFs play a relevant role in the development of depression with onset between ages 50 and 69 years, but no evidence was found that they contribute to the occurrence of depression with onset at age >/=70 years. Replication is warranted to exclude the possibility of bias. (aut. ref.

Longitudinal bidirectional associations between internalizing mental disorders and cardiometabolic disorders in the general adult population

Purpose This prospective population-based study investigated whether having any internalizing mental disorder (INT) was associated with the presence and onset of any cardiometabolic disorder (CM) at 3-year follow-up; and vice versa. Furthermore, we examined whether observed associations differed when using longer time intervals of respectively 6 and 9 years. Methods Data were used from the four waves (baseline and 3-, 6- and 9-year follow-up) of the Netherlands Mental Health Survey and Incidence Study-2, a prospective study of a representative cohort of adults. At each wave, the presence and first onset of INT (i.e. any mood or anxiety disorder) were assessed with the Composite International Diagnostic Interview 3.0; the presence and onset of CM (i.e. hypertension, diabetes, heart disease, and stroke) were based on self-report. Multilevel logistic autoregressive models were controlled for previous-wave INT and CM, respectively, and sociodemographic, clinical, and lifestyle covariates. Results Having any INT predicted both the presence (OR 1.28, p = 0.029) and the onset (OR 1.46, p = 0.003) of any CM at the next wave (3-year intervals). Having any CM was not significantly related to the presence of any INT at 3-year follow-up, while its association with the first onset of any INT reached borderline significance (OR 1.64, p = 0.06), but only when examining 6-year intervals. Conclusions Our findings indicate that INTs increase the risk of both the presence and the onset of CMs in the short term, while CMs may increase the likelihood of the first onset of INTs in the longer term. Further research is needed to better understand the mechanisms underlying the observed associations

The relationship between severity of Alzheimer's disease and prevalence of comorbid depressive symtoms and depression: A systematic review

Objectives: To gain more insight into the association between severity of Alzheimer's Disease (AD) and prevalence of comborbid depression. Methods: A systematic literature review based on the Cochrane methodology was performed. PubMed, PsychINFO and EMBASE databases were searched for existing studies that fulfilled predefined inclusion criteria. The studies were divided into: (1) those that analysed the association between severity of AD and prevalence of depressive symptoms ('continuous' approach) and (2) those that investigated the association between severity of AD and diagnosed depression ('categorical' approach). The quality of existing studies was rated and the results were synthesized with a best evidence synthesis. Results: Twenty-four studies fulfilled the inclusion criteria. Nineteen reported results for a continuous approach and seven for a categorical approach. Three of the four high quality studies within the continuous approach did not find a significant association between severity of AD and prevalence of depressive symptoms. None of the three high quality studies using the categorical approach found a significant association between the severity of AD and the prevalence of diagnosed depression. Conclusions: There is evidence for a lack of association between the severity of AD and the prevalence of comorbid depressive symptoms or diagnosed depression. Until new studies contradict this conclusion, prevention and intervention strategies for comorbid depression in AD should be aimed at all patients irrespective their disease severity

The bidirectional relationship between loneliness and common mental disorders in adults: findings from a longitudinal population-based cohort study

PURPOSE: Limited longitudinal population-based research exists on the bidirectional association between loneliness and common mental disorders (CMDs). Using 3-year follow-up data, this study examined whether loneliness among adults increases the risk for onset and persistence of mild-moderate or severe CMD; and whether mild-moderate or severe CMD is a risk factor for onset and persistence of loneliness. METHODS: Data were used from the second ('baseline') and third (3-year follow-up) waves of the Netherlands Mental Health Survey and Incidence Study-2, a prospective study of a representative cohort of adults aged 18-64 years. Twelve-month CMDs and their severity were assessed with the Composite International Diagnostic Interview 3.0, and current loneliness using the De Jong Gierveld Loneliness Scale. Multivariate analyses were controlled for several potential confounders. RESULTS: Loneliness predicted onset of severe CMD at follow-up in adults without CMDs at baseline, and increased risk for persistent severe CMD at follow-up in those with CMD at baseline. Conversely, severe CMD predicted onset of loneliness at follow-up in non-lonely adults at baseline, but was not associated with persistent loneliness at follow-up in lonely adults at baseline. Observed associations remained significant after controlling for perceived social support at baseline, except for the relationship between loneliness and persistent severe CMD. No longitudinal relationships were observed between loneliness and mild-moderate CMD. CONCLUSIONS: Attention should be paid to loneliness, both in adults with and without CMD. Further research is needed to better understand the mechanisms underlying the observed associations between loneliness and CMDs to develop successful interventions

Impact of Preexisting Depression on Length of Stay and Discharge Destination Among Patients Hospitalized for Acute Stroke : Linked Register-Based Study

Background and Purpose—There exists limited knowledge regarding the relation between depression and healthcare utilization in stroke patients. The objective of this register-based study was to examine the impact of having preexisting depression at the time of hospital admission for acute stroke on length of hospital stay and discharge destination. Methods—Data from a general-practice database were linked to those of a hospital database to identify patients hospitalized for stroke and were used to categorize these patients into 3 groups based on preexisting mental health (MH) status at admission, ie, those with preexisting depression, those with another preexisting MH condition, and those without any preexisting MH condition. Multilevel analyses controlling for several potentially important covariates were performed to estimate the associations under study. Results—Both patients with preexisting depression (n41) and those with another preexisting MH condition (n62) did not differ significantly from patients without any preexisting MH condition (n211) regarding length of hospital stay for acute stroke. Among patients who survived hospitalization, those with preexisting depression had significantly higher odds of being discharged to an institution instead of their home than did patients without any preexisting MH condition. Having another preexisting MH condition had no significant effect on discharge destination. Conclusions—Having preexisting depression at admission seems to be a relevant factor in determining discharge to institutional care after acute stroke hospitalization. Further research is needed to determine the mechanism(s) through which preexisting depression decreases the chances of being discharged to home.
