Identification , course , and treatment of depression after admission for a cardiac condition : rationale and patient characteristics for the Identifying Depression As a Comorbid Condition ( IDACC ) project . BACKGROUND Given the prevalence of cardiovascular disease and the high rates of depression among cardiac patients , there is a need to develop practical ways to identify this population and provide pragmatic general-practitioner-based interventions for managing depression as a comorbid condition . METHOD The Identifying Depression As a Comorbid Condition ( IDACC ) study employed a hybrid design , incorporating a randomized controlled trial nested within a prospective cohort study . IDACC screened for depression in patients hospitalized in South Australia for a range of cardiac conditions , with outcome measures monitored for 12 months after discharge . The subgroup identified as depressed was entered into the nested IDACC trial , which tests the hypothesis that identifying depression and offering an evidence-based intervention to general practitioners , incorporating multidisciplinary telephone case conferencing , will reduce levels of depression , improve quality of life , and reduce associated economic costs . RESULTS At baseline , 46.3 % of 1455 participants screened were classified as depression cases on the basis of their score on the Center for Epidemiological Studies Depression Scale ( > or =16 ) or the Hospital Anxiety and Depression Scale ( > or =8 ) . Elevated scores were associated with being younger , female , divorced or separated , not employed , living alone , having a lower level of education , and having poorer health and quality of life . Nearly one fifth ( 19.4 % ) of participants had Center for Epidemiological Studies Depression Scale scores > 27 , which is indicative of major depression . CONCLUSIONS This project confirms , in an Australian setting , the high prevalence of depressive symptoms among hospitalized cardiac patients . Follow-up over 12 months will enhance understanding of the natural history of depression in cardiac patients , while the nested trial will inform on effectiveness of an intervention involving tailored advice and support to general practitioners .
