Panic disorder and generalized anxiety disorder are prevalent in primary care, associated with poor functional outcomes, and are often unrecognized and ineffectively treated by primary care physicians.
                To examine whether telephone-based collaborative care for panic and generalized anxiety disorders improves clinical and functional outcomes more than the usual care provided by primary care physicians.
                Randomized controlled trial.
                Four Pittsburgh area primary care practices linked by a common electronic medical record system. Patients A total of 191 adults aged 18 to 64 years with panic and/or generalized anxiety disorder who were recruited from July 2000 to April 2002. Intervention Patients were randomly assigned to a telephone-based care management intervention (n = 116) or to notification alone of the anxiety disorder to patients and their physicians (usual care, n = 75). The intervention involved non-mental health professionals who provided patients with psychoeducation, assessed preferences for guideline-based care, monitored treatment responses, and informed physicians of their patients' care preferences and progress via an electronic medical record system under the direction of study investigators.
                Independent blinded assessments of anxiety and depressive symptoms, mental health-related quality of life, and employment status at baseline, 2-, 4-, 8-, and 12-month follow-up.
                At 12-month follow-up, intervention patients reported reduced anxiety (effect size [ES], 0.33-0.38; 95% confidence interval [CI], 0.04 to 0.67; P</=.02) and depressive symptoms (ES, 0.35; 95% CI, 0.25-0.46; P = .03); improved mental health-related quality of life (ES, 0.39; 95% CI, 0.10 to 0.68; P = .01); and larger improvements relative to baseline in hours worked per week (5.7; 95% CI, 0.1 to 11.3; P = .05) and fewer work days absent in the past month (-2.6; 95% CI, - 4.8 to -0.3; P = .03) than usual care patients. If working at baseline, more intervention patients than usual care patients remained working at 12-month follow-up (94% vs 79% [15% absolute difference, 0.7%-28.6%]; P = .04).
                Telephone-based collaborative care for panic disorder and generalized anxiety disorder is more effective than usual care at improving anxiety symptoms, health-related quality of life, and work-related outcomes. There is a high prevalence of depression in patients with diabetes mellitus. Depression has been shown to be associated with poor self-management (adherence to diet, exercise, checking blood glucose levels) and high hemoglobin A1c (HbA1c) levels in patients with diabetes.
                To determine whether enhancing quality of care for depression improves both depression and diabetes outcomes in patients with depression and diabetes.
                Randomized controlled trial with recruitment from March 1, 2001, to May 31, 2002.
                Nine primary care clinics from a large health maintenance organization.
                A total of 329 patients with diabetes mellitus and comorbid major depression and/or dysthymia. Intervention Patients were randomly assigned to the Pathways case management intervention (n = 164) or usual care (n = 165). The intervention provided enhanced education and support of antidepressant medication treatment prescribed by the primary care physician or problem-solving therapy delivered in primary care.
                Independent blinded assessments at baseline and 3, 6, and 12 months of depression (Hopkins Symptom Checklist 90), global improvement, and satisfaction with care. Automated clinical data were used to evaluate adherence to antidepressant regimens, percentage receiving specialty mental health visits, and HbA1c levels.
                When compared with usual care patients, intervention patients showed greater improvement in adequacy of dosage of antidepressant medication treatment in the first 6-month period (odds ratio [OR], 4.15; 95% confidence interval [CI], 2.28-7.55) and the second 6-month period (OR, 2.90; 95% CI, 1.69-4.98), less depression severity over time (z = 2.84, P = .004), a higher rating of patient-rated global improvement at 6 months (intervention 69.4% vs usual care 39.3%; OR, 3.50; 95% CI, 2.16-5.68) and 12 months (intervention 71.9% vs usual care 42.3%; OR, 3.50; 95% CI, 2.14-5.72), and higher satisfaction with care at 6 months (OR, 2.01; 95% CI, 1.18-3.43) and 12 months (OR, 2.88; 95% CI, 1.67-4.97). Although depressive outcomes were improved, no differences in HbA1c outcomes were observed.
                The Pathways collaborative care model improved depression care and outcomes in patients with comorbid major depression and/or dysthymia and diabetes mellitus, but improved depression care alone did not result in improved glycemic control. Effectiveness studies have tested interventions to improve quality of care for depression in primary care, but none, to our knowledge, have been completed for panic disorder (PD) in this setting. This study sought to test the clinical effectiveness of PD pharmacotherapy embedded in a disease management framework of "collaborative care" (CC).
                One hundred fifteen patients with PD from 3 primary care clinics were randomized to CC or "usual care" (UC). Patients in CC (n = 57) received educational videotapes and pamphlets; pharmacotherapy with the selective serotonin reuptake inhibitor paroxetine; 2 psychiatrist visits and 2 telephone calls in the first 8 weeks; and up to 5 telephone calls between 3 and 12 months' follow-up. Usual care patients (n = 58) were treated by their primary care physician. Telephone assessments of panic, anxiety sensitivity, depression, and disability variables were performed at 3, 6, 9, and 12 months' follow-up. Adequacy of pharmacotherapy was assessed with an algorithm based on a review of efficacy studies.
                Patients in CC were more likely to receive adequate (type, dose, duration) medication and more likely to adhere to this medication at 3 and 6 months. Random regression analyses showed that CC patients improved significantly more over time compared with UC patients on anxiety, depression, and disability measures, with the greatest effects at 3 and 6 months.
                Compared with UC, CC interventions significantly improved both quality of care and clinical and functional outcomes in primary care PD patients. Clinical differences were greatest in the first 6 months, corresponding to the greater quality of care and the greater intensity of intervention. To determine whether evidence-based socioculturally adapted collaborative depression care improves receipt of depression care and depression and diabetes outcomes in low-income Hispanic subjects.
                This was a randomized controlled trial of 387 diabetic patients (96.5% Hispanic) with clinically significant depression recruited from two public safety-net clinics from August 2005 to July 2007 and followed over 18 months. Intervention (INT group) included problem-solving therapy and/or antidepressant medication based on a stepped-care algorithm; first-line treatment choice; telephone treatment response, adherence, and relapse prevention follow-up over 12 months; plus systems navigation assistance. Enhanced usual care (EUC group) included standard clinic care plus patient receipt of depression educational pamphlets and a community resource list.
                INT patients had significantly greater depression improvement (> or =50% reduction in Symptom Checklist-20 depression score from baseline; 57, 62, and 62% vs. the EUC group's 36, 42, and 44% at 6, 12, and 18 months, respectively; odds ratio 2.46-2.57; P < 0.001). Mixed-effects linear regression models showed a significant study group-by-time interaction over 18 months in diabetes symptoms; anxiety; Medical Outcomes Study Short-Form Health Survey (SF-12) emotional, physical, and pain-related functioning; Sheehan disability; financial situation; and number of social stressors (P = 0.04 for disability and SF-12 physical functioning, P < 0.001 for all others) but no study group-by-time interaction in A1C, diabetes complications, self-care management, or BMI.
                Socioculturally adapted collaborative depression care improved depression, functional outcomes, and receipt of depression treatment in predominantly Hispanic patients in safety-net clinics. Depression and anxiety are the most common psychiatric conditions in late life. Despite their prevalence, we know relatively little about their unique manifestation in older adults. And, Although the most common intervention for late-life depression and anxiety continues to be medication, research on psychosocial interventions for late-life depression and anxiety has burgeoned in the past several years. Unfortunately, this growing body of intervention research has yet to be widely translated into improved systems of care for late-life depression. This article is one step toward synthesizing the knowledge in this growing area of research. The review of literature presents the conclusions of several meta-analyses that have reviewed psychosocial interventions for late-life depression and anxiety. In addition, intervention studies concerning the effectiveness of cognitive behavioral therapy, interpersonal therapy, reminiscence therapy, and alternative therapies with depressed and/or anxious older adults are reviewed. A brief description of various approaches to psychosocial intervention with anxious and/or depressed older adults is also presented. To determine the effect of collaborative care management for depression on physical functioning in older adults.
                Multisite randomized clinical trial.
                Eighteen primary care clinics from eight healthcare organizations.
                One thousand eight hundred one patients aged 60 and older with major depressive disorder.
                Patients were randomized to the Improving Mood: Promoting Access to Collaborative Treatment (IMPACT) intervention (n=906) or to a control group receiving usual care (n=895). Control patients had access to all health services available as part of usual care. Intervention patients had access for 12 months to a depression clinical specialist who coordinated depression care with their primary care physician.
                The 12-item short form Physical Component Summary (PCS) score (range 0-100) and instrumental activities of daily living (IADLs) (range 0-7).
                The mean patient age was 71.2, 65% were women, and 77% were white. At baseline, the mean PCS was 40.2, and the mean number of IADL dependencies was 0.7; 45% of participants rated their health as fair or poor. Intervention patients experienced significantly better physical functioning at 1 year than usual-care patients as measured using between-group differences on the PCS of 1.71 (95% confidence interval (CI)=0.96-2.46) and IADLs of -0.15 (95% CI=-0.29 to -0.01). Intervention patients were also less likely to rate their health as fair or poor (37.3% vs 52.4%, P<.001). Combining both study groups, patients whose depression improved were more likely to experience improvement in physical functioning.
                The IMPACT collaborative care model for late-life depression improves physical function more than usual care. This study examined whether a collaborative care model for depression would improve clinical and functional outcomes for depressed patients with chronic general medical conditions in primary care practices in Puerto Rico.
                A total of 179 primary care patients with major depression and chronic general medical conditions were randomly assigned to receive collaborative care or usual care. The collaborative care intervention involved enhanced collaboration among physicians, mental health specialists, and care managers paired with depression-specific treatment guidelines, patient education, and follow-up. In usual care, study personnel informed the patient and provider of the diagnosis and encouraged patients to discuss treatment options with their provider. Depression severity was assessed with the Hopkins Symptom Checklist; social functioning was assessed with the 36-item Short Form.
                Compared with usual care, collaborative care significantly reduced depressive symptoms and improved social functioning in the six months after randomization. Integration of collaborative care in primary care practices considerably increased depressed patients' use of mental health services.
                Collaborative care significantly improved clinical symptoms and functional status of depressed patients with coexisting chronic general medical conditions receiving treatment for depression in primary care practices in Puerto Rico. These findings highlight the promise of the collaborative care model for strengthening the relationship between mental health and primary care services in Puerto Rico. Depression in cardiac patients is common, under-recognized, and independently associated with mortality.
                Our objectives in this initial report from a 6-month longitudinal trial were to determine whether a collaborative care program improves rates of depression treatment by discharge among patients hospitalized with acute cardiovascular disease, and to assess key clinical characteristics of depression in this cohort.
                This was a prospective, randomized trial comparing collaborative care and usual care interventions for depressed cardiac patients who were admitted to cardiac units in an urban academic medical center. For collaborative care subjects, the care manager performed a multi-component depression intervention in the hospital that included patient education and treatment coordination; usual care subjects' inpatient providers were informed of the depression diagnosis.
                The mean Patient Health Questionnaire-9 for subjects (N = 175) was 17.6 (SD 3.5; range 11-26), consistent with moderate-severe depression. The majority of subjects had depression for over one month (n = 134; 76.6%) and a prior depressive episode (n = 124; 70.8%); nearly one-half (n = 75; 42.9%) had thoughts that life was not worth living in the preceding 2 weeks. Collaborative care subjects were far more likely to receive adequate depression treatment by discharge (71.9% collaborative care vs. 9.5% usual care; p < 0.001).
                Depression identified by systematic screening in hospitalized cardiac patients appears was prolonged, and of substantial severity. A collaborative care depression management model appears to vastly increase rates of appropriate treatment by discharge.

The MANAS trial aimed to test the effectiveness of an intervention led by lay health counsellors in primary care settings to improve outcomes of people with these disorders.
                In this cluster randomised trial, primary care facilities in Goa, India, were assigned (1:1) by computer-generated randomised sequence to intervention or control (enhanced usual care) groups. All adults who screened positive for common mental disorders were eligible. The collaborative stepped-care intervention offered case management and psychosocial interventions, provided by a trained lay health counsellor, supplemented by antidepressant drugs by the primary care physician and supervision by a mental health specialist. The research assessor was masked. The primary outcome was recovery from common mental disorders as defined by the International Statistical Classification of Diseases and Related Health Problems-10th revision (ICD-10) at 6 months. This study is registered with ClinicalTrials.gov, number NCT00446407.
                24 study clusters, with an equal proportion of public and private facilities, were randomised equally between groups. 1160 of 1360 (85%) patients in the intervention group and 1269 of 1436 (88%) in the control group completed the outcome assessment. Patients with ICD-10-confirmed common mental disorders in the intervention group were more likely to have recovered at 6 months than were those in the control group (n=620 [65·0%] vs 553 [52·9%]; risk ratio 1·22, 95% CI 1·00-1·47; risk difference=12·1%, 95% CI 1·6%-22·5%). The intervention had strong evidence of an effect in public facility attenders (369 [65·9%] vs 267 [42·5%], risk ratio 1·55, 95% CI 1·02-2·35) but no evidence for an effect in private facility attenders (251 [64·1%] vs 286 [65·9%], risk ratio 0·95, 0·74-1·22). There were three deaths and four suicide attempts in the collaborative stepped-care group and six deaths and six suicide attempts in the enhanced usual care group. None of the deaths were from suicide.
                A trained lay counsellor-led collaborative care intervention can lead to an improvement in recovery from CMD among patients attending public primary care facilities.

The aim of this study was to determine both the clinical and cost-effectiveness of usual general practitioner (GP) care compared with two types of brief psychological therapy (non-directive counselling and cognitive-behaviour therapy) in the management of depression as well as mixed anxiety and depression in the primary care setting.
                The design was principally a pragmatic randomised controlled trial, but was accompanied by two additional allocation methods allowing patient preference: the option of a specific choice of treatment (preference allocation) and the option to be randomised between the psychological therapies only. Of the 464 patients allocated to the three treatments, 197 were randomised between the three treatments, 137 chose a specific treatment, and 130 were randomised between the psychological therapies only. The patients underwent follow-up assessments at 4 and 12 months.
                The study was conducted in 24 general practices in Greater Manchester and London.
                A total of 464 eligible patients, aged 18 years and over, were referred by 73 GPs and allocated to one of the psychological therapies or usual GP care for depressive symptoms.
                The interventions consisted of brief psychological therapy (12 sessions maximum) or usual GP care. Non-directive counselling was provided by counsellors who were qualified for accreditation by the British Association for Counselling. Cognitive-behaviour therapy was provided by clinical psychologists who were qualified for accreditation by the British Association for Behavioural and Cognitive Psychotherapies. Usual GP care included discussions with patients and the prescription of medication, but GPs were asked to refrain from referring patients for psychological intervention for at least 4 months. Most therapy sessions took place on a weekly basis in the general practices. By the 12-month follow-up, GP care in some cases did include referral to mental healthcare specialists.
                The clinical outcomes included depressive symptoms, general psychiatric symptoms, social function and patient satisfaction. The economic outcomes included direct and indirect costs and quality of life. Assessments were carried out at baseline during face-to-face interviews as well as at 4 and 12 months in person or by post.
                At 4 months, both psychological therapies had reduced depressive symptoms to a significantly greater extent than usual GP care. Patients in the psychological therapy groups exhibited mean scores on the Beck Depression Inventory that were 4-5 points lower than the mean score of patients in the usual GP care group, a difference that was also clinically significant. These differences did not generalize to other measures of outcome. There was no significant difference in outcome between the two psychological therapies when they were compared directly using all 260 patients randomised to a psychological therapy by either randomised allocation method. At 12 months, the patients in all three groups had improved to the same extent. The lack of a significant difference between the treatment groups at this point resulted from greater improvement of the patients in the GP care group between the 4- and 12-month follow-ups. At 4 months, patients in both psychological therapy groups were more satisfied with their treatment than those in the usual GP care group. However, by 12 months, patients who had received non-directive counselling were more satisfied than those in either of the other two groups. There were few differences in the baseline characteristics of patients who were randomised or expressed a treatment preference, and no differences in outcome between these patients. Similar outcomes were found for patients who chose either psychological therapy. Again, there were no significant differences between the two groups at 4 or 12 months. Patients who chose counselling were more satisfied with treatment than those who chose c Approximately 10% to 16% of women experience a major depressive episode after childbirth. A significant proportion of these women also suffer from comorbid anxiety disorders. The purpose of this study was to evaluate whether the addition of cognitive-behavioral therapy (CBT) to standard antidepressant therapy offers additional benefits in the treatment of post-partum depression with comorbid anxiety disorders.
                Thirty-five women referred to a tertiary care hospital outpatient program with a DSM-IV diagnosis of postpartum depression with comorbid anxiety disorder were randomly assigned to 1 of 2 treatment groups-paroxetine-only monotherapy group (N = 16) or paroxetine plus 12 sessions of CBT combination therapy group (N = 19)-for a 12-week trial. Progress was monitored by a psychiatrist blinded to treatment group, using the Hamilton Rating Scale for Depression, Hamilton Rating Scale for Anxiety, Yale-Brown Obsessive Compulsive Scale, Clinical Global Impressions scale, and Edinburgh Postnatal Depression Scale. Data were analyzed using 2-tailed statistical tests at an alpha level of.05. The study was conducted from April 1, 2002, to June 30, 2003.
                Both treatment groups showed a highly significant improvement (p <.01) in mood and anxiety symptoms. Groups did not differ significantly in week of recovery, dose of paroxetine at remission, or measures of depression, anxiety, and obsessive-compulsive symptoms at outcome.
                Antidepressant monotherapy and combination therapy with antidepressants and CBT were both efficacious in reducing depression and anxiety symptoms. However, in this sample of acutely depressed/anxious postpartum women, there were no additional benefits from combining the 2 treatment modalities. Further research into the efficacy of combination therapy in the treatment of moderate-to-severe depression with comorbid disorders in postpartum women is recommended.
Collaborative care is associated with significant improvement in depression and anxiety outcomes compared with usual care, and represents a useful addition to clinical pathways for adult patients with depression and anxiety.
