    Input: This paper describes the rationale and design of the vanguard for the Comparison of Depression Interventions after Acute Coronary Syndrome ( CODIACS ) , a multicenter , r and omized , controlled trial of a patient preference-based , stepped care protocol for persistent depressive symptoms after acute coronary syndrome ( ACS ) . The overall aim of the vanguard phase was to determine whether the patient-preference , stepped care protocol , which is based on the intervention used in the recent Coronary Psychosocial Evaluation Studies ( COPES ) trial , was feasible in patients with recent ACS who were recruited from 5 geographically diverse sites . Innovative design features of this trial include r and omization to either initial patient-preference of treatment or to a referred care arm in which the primary care provider decided upon care . Additionally , delivery of psychotherapy was accomplished by telephone , or webcam , depending upon patient preference . The vanguard phase provides estimates of eligibility and screening/enrollment ratios , patient acceptance of screening , and retention . In this report , we describe the innovative features and the baseline results of the vanguard phase of CODIACS . The data from this vanguard study will be used to finalize planning for a large , phase III clinical trial design ed to evaluate the effect of treatment on depressive symptoms , coronary events , and death CONTEXT Depression and low perceived social support ( LPSS ) after myocardial infa rct ion ( MI ) are associated with higher morbidity and mortality , but little is known about whether this excess risk can be reduced through treatment . OBJECTIVE To determine whether mortality and recurrent infa rct ion are reduced by treatment of depression and LPSS with cognitive behavior therapy ( CBT ) , supplemented with a selective serotonin reuptake inhibitor ( SSRI ) antidepressant when indicated , in patients enrolled within 28 days after MI . DESIGN , SETTING , AND PATIENTS R and omized clinical trial conducted from October 1996 to April 2001 in 2481 MI patients ( 1084 women , 1397 men ) enrolled from 8 clinical centers . Major or minor depression was diagnosed by modified Diagnostic and Statistical Manual of Mental Disorders , Fourth Edition criteria and severity by the 17-item Hamilton Rating Scale for Depression ( HRSD ) ; LPSS was determined by the Enhancing Recovery in Coronary Heart Disease Patients ( ENRICHD ) Social Support Instrument ( ESSI ) . R and om allocation was to usual medical care or CBT-based psychosocial intervention . INTERVENTION Cognitive behavior therapy was initiated at a median of 17 days after the index MI for a median of 11 individual sessions throughout 6 months , plus group therapy when feasible , with SSRIs for patients scoring higher than 24 on the HRSD or having a less than 50 % reduction in Beck Depression Inventory scores after 5 weeks . MAIN OUTCOME MEASURES Composite primary end point of death or recurrent MI ; secondary outcomes included change in HRSD ( for depression ) or ESSI scores ( for LPSS ) at 6 months . RESULTS Improvement in psychosocial outcomes at 6 months favored treatment : mean ( SD ) change in HRSD score , -10.1 ( 7.8 ) in the depression and psychosocial intervention group vs -8.4 ( 7.7 ) in the depression and usual care group ( P<.001 ) ; mean ( SD ) change in ESSI score , 5.1 ( 5.9 ) in the LPSS and psychosocial intervention group vs 3.4 ( 6.0 ) in the LPSS and usual care group ( P<.001 ) . After an average follow-up of 29 months , there was no significant difference in event-free survival between usual care ( 75.9 % ) and psychosocial intervention ( 75.8 % ) . There were also no differences in survival between the psychosocial intervention and usual care arms in any of the 3 psychosocial risk groups ( depression , LPSS , and depression and LPSS patients ) . CONCLUSIONS The intervention did not increase event-free survival . The intervention improved depression and social isolation , although the relative improvement in the psychosocial intervention group compared with the usual care group was less than expected due to substantial improvement in usual care patients Background Community studies reveal people with coronary heart disease ( CHD ) are twice as likely to be depressed as the general population and that this co-morbidity negatively affects the course and outcome of both conditions . There is evidence for the efficacy of collaborative care and case management for depression treatment , and whilst NICE guidelines recommend these approaches only where depression has not responded to psychological , pharmacological , or combined treatments , these care approaches may be particularly relevant to the needs of people with CHD and depression in the earlier stages of stepped care in primary care setting s. Methods This pilot r and omised controlled trial will evaluate whether a simple intervention involving a personalised care plan , elements of case management and regular telephone review is a feasible and acceptable intervention that leads to better mental and physical health outcomes for these patients . The comparator group will be usual general practitioner ( GP ) care.81  participants have been recruited from CHD registers of 15 South London general practice s. Eligible participants have probable major depression identified by a score of ≥8 on the Hospital Anxiety and Depression Scale depression subscale ( HADS-D ) together with symptomatic CHD identified using the Modified Rose Angina Question naire . Consenting participants are r and omly allocated to usual care or the personalised care intervention which involves a comprehensive assessment of each participant ’s physical and mental health needs which are documented in a care plan , followed by regular telephone review s by the case manager over a 6-month period . At each review , the intervention participant ’s mood , function and identified problems are review ed and the case manager uses evidence based behaviour change techniques to facilitate achievement of goals specified by the patient with the aim of increasing the patient ’s self efficacy to solve their problems . Depressive symptoms measured by HADS score will be collected at baseline and 1 , 6- and 12 months post r and omisation . Other outcomes include CHD symptoms , quality of life , wellbeing and health service utilisation . Discussion This practical and patient-focused intervention is potentially an effective and accessible approach to the health and social care needs of people with depression and CHD in primary care . Trial registration IS RCT N21615909 Background In the presence of type 2 diabetes ( T2DM ) or coronary heart disease ( CHD ) , depression is under diagnosed and under treated despite being associated with worse clinical outcomes . Our earlier pilot study demonstrated that it was feasible , acceptable and affordable for practice nurses to extend their role to include screening for and monitoring of depression alongside biological and lifestyle risk factors . The current study will compare the clinical outcomes of our model of practice nurse-led collaborative care with usual care for patients with depression and T2DM or CHD . Methods This is a cluster-r and omised intervention trial . Eighteen general practice s from regional and metropolitan areas agreed to join this study , and were allocated r and omly to an intervention or control group . We aim to recruit 50 patients with co-morbid depression and diabetes or heart disease from each of these practice s. In the intervention group , practice nurses ( PNs ) will be trained for their enhanced roles in this nurse-led collaborative care study . Patients will be invited to attend a practice nurse consultation every 3 months prior to seeing their usual general practitioner . The PN will assess psychological , physiological and lifestyle parameters then work with the patient to set management goals . The outcome of this assessment will form the basis of a GP Management Plan document . In the control group , the patients will continue to receive their usual care for the first six months of the study before the PNs undergo the training and switch to the intervention protocol . The primary clinical outcome will be a reduction in the depression score . The study will also measure the impact on physiological measures , quality of life and on patient attitude to health care delivered by practice nurses . Conclusion The strength of this programme is that it provides a sustainable model of chronic disease management with monitoring and self-management assistance for physiological , lifestyle and psychological risk factors for high-risk patients with co-morbid depression , diabetes or heart disease . The study will demonstrate whether nurse-led collaborative care achieves better outcomes than usual care BACKGROUND Patients with depression and poorly controlled diabetes , coronary heart disease , or both have an increased risk of adverse outcomes and high health care costs . We conducted a study to determine whether coordinated care management of multiple conditions improves disease control in these patients . METHODS We conducted a single-blind , r and omized , controlled trial in 14 primary care clinics in an integrated health care system in Washington State , involving 214 participants with poorly controlled diabetes , coronary heart disease , or both and coexisting depression . Patients were r and omly assigned to the usual-care group or to the intervention group , in which a medically supervised nurse , working with each patient 's primary care physician , provided guideline -based , collaborative care management , with the goal of controlling risk factors associated with multiple diseases . The primary outcome was based on simultaneous modeling of glycated hemoglobin , low-density lipoprotein ( LDL ) cholesterol , and systolic blood-pressure levels and Symptom Checklist-20 ( SCL-20 ) depression outcomes at 12 months ; this modeling allowed estimation of a single overall treatment effect . RESULTS As compared with controls , patients in the intervention group had greater overall 12-month improvement across glycated hemoglobin levels ( difference , 0.58 % ) , LDL cholesterol levels ( difference , 6.9 mg per deciliter [ 0.2 mmol per liter ] ) , systolic blood pressure ( difference , 5.1 mm Hg ) , and SCL-20 depression scores ( difference , 0.40 points ) ( P<0.001 ) . Patients in the intervention group also were more likely to have one or more adjustments of insulin ( P=0.006 ) , antihypertensive medications ( P<0.001 ) , and antidepressant medications ( P<0.001 ) , and they had better quality of life ( P<0.001 ) and greater satisfaction with care for diabetes , coronary heart disease , or both ( P<0.001 ) and with care for depression ( P<0.001 ) . CONCLUSIONS As compared with usual care , an intervention involving nurses who provided guideline -based , patient-centered management of depression and chronic disease significantly improved control of medical disease and depression . ( Funded by the National Institute of Mental Health ; Clinical Trials.gov number , NCT00468676 . ) Objectives To determine the effectiveness of collaborative care in reducing depression in primary care patients with diabetes or heart disease using practice nurses as case managers . Design A two-arm open r and omised cluster trial with wait-list control for 6 months . The intervention was followed over 12 months . Setting Eleven Australian general practice s , five r and omly allocated to the intervention and six to the control . Participants 400 primary care patients ( 206 intervention , 194 control ) with depression and type 2 diabetes , coronary heart disease or both . Intervention The practice nurse acted as a case manager identifying depression , review ing pathology results , lifestyle risk factors and patient goals and priorities . Usual care continued in the controls . Main outcome measure A five-point reduction in depression scores for patients with moderate-to-severe depression . Secondary outcome was improvements in physiological measures . Results Mean depression scores after 6 months of intervention for patients with moderate-to-severe depression decreased by 5.7±1.3 compared with 4.3±1.2 in control , a significant ( p=0.012 ) difference . ( The plus – minus is the 95 % confidence range . ) Intervention practice s demonstrated adherence to treatment guidelines and intensification of treatment for depression , where exercise increased by 19 % , referrals to exercise programmes by 16 % , referrals to mental health workers ( MHWs ) by 7 % and visits to MHWs by 17 % . Control- practice exercise did not change , whereas referrals to exercise programmes  dropped by 5 % and visits to MHWs by 3 % . Only referrals to MHW increased by 12 % . Intervention improvements were sustained over 12 months , with a significant ( p=0.015 ) decrease in 10-year cardiovascular disease risk from 27.4±3.4 % to 24.8±3.8 % . A review of patients indicated that the study 's safety protocol s were followed . Conclusions TrueBlue participants showed significantly improved depression and treatment intensification , sustained over 12 months of intervention and reduced 10-year cardiovascular disease risk . Collaborative care using practice nurses appears to be an effective primary care intervention . Trial registration ACTRN12609000333213 ( Australia and New Zeal and Clinical Trials Registry ) Objective : To present the design of the Bypassing the Blues ( BtB ) study to examine the impact of a collaborative care strategy for treating depression among patients with cardiac disease .  Coronary artery bypass graft ( CABG ) surgery is one of the most common and costly medical procedures performed in the US . Up to half of post-CABG patients report depressive symptoms , and they are more likely to experience poorer health-related quality of life ( HRQoL ) , worse functional status , continued chest pains , and higher risk of cardiovascular morbidity independent of cardiac status , medical comorbidity , and the extent of bypass surgery . Methods : BtB was design ed to enroll 450 post-CABG patients from eight Pittsburgh-area hospitals including : ( 1 ) 300 patients who expressed mood symptoms preceding discharge and at 2 weeks post hospitalization ( Patient Health Question naire ( PHQ-9 ) ≥10 ) ; and ( 2 ) 150 patients who served as
