Background: Many patients with anxiety or depressive disorders achieve no remission of their symptoms after evidence-based treatment algorithms. They develop a chronic course of the disorder. Current care for these patients usually consists of long-term supportive contacts with a community psychiatric nurse and pharmacological management by a psychiatrist. Data on the effectiveness of these treatments is lacking. A psychosocial rehabilitation approach, where self-management is an increasingly important part, could be more suitable. It focuses on the restoration of functioning and enhancement of patients' autonomy and responsibility. Treatment with this focus, followed by referral to primary care, may be more (cost-)effective. Methods: A multicenter randomized controlled trial is designed for twelve participating specialized outpatient mental health services in the Netherlands. Patients with chronic and treatment resistant anxiety or depressive disorders, currently receiving supportive care in specialized outpatient mental health care, are asked to participate. After inclusion, patients receive the baseline questionnaire and are randomized to the intervention group or the usual care control group. The intervention focuses on rehabilitation and self-management and is provided by a trained community psychiatric nurse, followed by referral to primary care. Measurements take place at 6, 12, and 18 months after baseline. This study evaluates both the effectiveness (on quality of life, symptom severity, and empowerment), and cost-effectiveness of the intervention compared to usual care. In addition, a questionnaire is designed to get insight in which self-management strategies patients use to manage their disorder, and in the experiences of patients with the change of care setting. Discussion: In this study we evaluate the effectiveness and cost-effectiveness of a self-management intervention for patients with chronic and treatment resistant anxiety or depressive disorders in specialized outpatient mental health care. The results of this study may provide a first 'proof-of-concept' in this under-researched but important field, and might be relevant for a large group of patients in the context of a transition of the Dutch health care system.

Background: Studies evaluating collaborative care for anxiety disorders are recently emerging. A systematic review and meta-analysis to estimate the effect of collaborative care for adult patients with anxiety disorders in primary care is therefore warranted. Methods: A literature search was performed. Data sources: PubMed, Psycinfo, Embase, Cinahl, and the Cochrane library. Study eligibility criteria: Randomized controlled trials examining the effects of collaborative care for adult primary care patients with an anxiety disorder, compared to care as usual or another intervention. Synthesis methods: Standardized mean differences (SMD) on an anxiety scale closest to twelve months follow-up were calculated and pooled in a random effects meta-analysis. Results: Of the 3073 studies found, seven studies were included with a total of 2105 participants. Included studies were of moderate to high quality. Collaborative care was superior to care as usual, with a small effect size (SMD = 0.35 95 % CI 0.14-0.56) for all anxiety disorders combined and a moderate effect size (SMD = 0.59, 95 % CI 0.41-0.78) in a subgroup analysis (five studies) on patients with panic disorder. Conclusions: Collaborative care seems to be a promising strategy for improving primary care for anxiety disorders, in particular panic disorder. However, the number of studies is still small and further research is needed to evaluate the effectiveness in other anxiety disorders. [ABSTRACT FROM AUTHOR]

Background: Questionnaires may help in detecting and diagnosing anxiety disorders in primary care. However, since utility of these questionnaires in target populations is rarely studied, the Patient Health Questionnaire anxiety modules (PHQ) were evaluated for use as: a) a screener in high-risk patients, and/or b) a case finder for general practitioners (GPs) to assist in diagnosing anxiety disorders. Methods: A cross-sectional analysis was performed in 43 primary care practices in the Netherlands. The added value of the PHQ was assessed in two samples: 1) 170 patients at risk of anxiety disorders (or developing them) according to their electronic medical records (high-risk sample); 2) 141 patients identified as a possible 'anxiety case' by a GP (GP-identified sample). All patients completed the PHQ and were interviewed using the Mini International Neuropsychiatric interview to classify DSM-IV anxiety disorders. Psychometric properties were calculated, and a logistic regression analysis was performed to assess the diagnostic value of the PHQ. Results: Using only the screening questions of the PHQ, the area under the curve was 83% in the high-risk sample. In GP-identified patients the official algorithm showed the best characteristics with an area under the curve of 77%. Positive screening questions significantly increased the odds of an anxiety disorder diagnosis in high-risk patients (odds ratio = 23.4; 95% confidence interval 6.9 to 78.8) as did a positive algorithm in GP-identified patients (odds ratio = 13.9; 95% confidence interval 3.8 to 50.6). Conclusions: The PHQ screening questions can be used to screen for anxiety disorders in high-risk primary care patients. In GP-identified patients, the benefit of the PHQ is less evident.
