ABSTRACT We sought to determine the rates and predictors of screening, screening positive, follow-up evaluation, and subsequent diagnosis of depression among medical outpatients.
This was a cross-sectional study using chart-review data from the Department of Veterans Affairs (VA) 2002 External Peer Review Program merged with administrative data.
We studied a national sample of VA medical outpatients with no depression diagnosis or mental health visits in the past 6 months (n = 21,489) and used chart-review and administrative data to follow the chain of events from depression screening to diagnosis.
Overall, 84.9% of eligible patients (n = 18,245) were screened for depression in the past year. Of the 8.8% who screened positive, only 54.0% received follow-up evaluation and, of these, 23.6% (n = 204) subsequently were diagnosed with a depressive disorder (representing 1.1% of the originally screened sample). Patients who were younger, unmarried, and had more medical comorbidities were less likely to be screened; however, if screened, they were more likely to screen positive. Male gender and greater medical comorbidity were associated with decreased odds of follow-up evaluation after a positive screen. At the facility level, likelihood of depression screening was inversely associated with spending on teaching and research but positively associated with spending on mental health care.
VA's depression case-finding activities yielded relatively few positive cases, raising questions about cost-effectiveness. Targeted strategies may increase the value of case-finding among patients at greatest risk for depression and at more academically affiliated medical centers. Targeted efforts also are needed to ensure proper follow-up evaluation of suspected cases, particularly among male patients and those with increased medical comorbidity.

    ABSTRACT: Despite strong efforts, the diagnosis and treatment of depression bring many challenges in the primary care setting. Screening for depression has been shown to be effective only if reliable systems of care are in place to ensure appropriate treatment by clinicians and adherence by patients. New evidence-based models of care for depression exist, but spread has been slow because of inadequate funding structures and conflicts within current clinical culture. The Affordable Care Act introduces potential opportunities to reorganize funding structures, conceivably leading to increased adoption of these collaborative care models. Suicide screening remains controversial. Copyright © 2015 Elsevier Inc. All rights reserved.

    ABSTRACT: Objective Depression has been associated with increased risk of heart failure (HF). Because anxiety is highly comorbid with depression, we sought to establish if anxiety, depression, or their co-occurrence is associated with incident HF.MethodsA retrospective cohort (N = 236,079) including Veteran's Administration patients (age, 50-80 years) free of cardiovascular disease (CVD) at baseline was followed up between 2001 and 2007. Cox proportional hazards models were computed to estimate the association between anxiety disorders alone, major depressive disorder (MDD) alone, and the combination of anxiety and MDD, with incident HF before and after adjusting for sociodemographics, CVD risk factors (Type 2 diabetes, hypertension, hyperlipidemia, obesity), nicotine dependence/personal history of tobacco use, substance use disorders (alcohol and illicit drug abuse/dependence), and psychotropic medication.ResultsCompared with unaffected patients, those with anxiety only, MDD only, and both disorders were at increased risk for incident HF in age-adjusted models (hazard ratio [HR] = 1.19 [ 95% confidence interval {CI} = 1.10-1.28], HR = 1.21 [95% CI = 1.13-1.28], and HR = 1.24 [95% CI = 1.17-1.32], respectively). After controlling for psychotropics in a full model, the association between anxiety only, MDD only, and both disorders and incident HF increased (HRs = 1.46, 1.56, and 1.74, respectively).Conclusions Anxiety disorders, MDD, and co-occurring anxiety and MDD are associated with incident HF in this large cohort of Veteran's Administration patients free of CVD at baseline. This risk of HF is greater after accounting for protective effects of psychotropic medications. Prospective studies are needed to clarify the role of depression and anxiety and their pharmacological treatment in the etiology of HF.

    ABSTRACT: Data mining approaches have been increasingly applied to the electronic health record and have led to the discovery of numerous clinical associations. Recent data mining studies have suggested a potential association between cat bites and human depression. To explore this possible association in more detail we first used administrative diagnosis codes to identify patients with either depression or bites, drawn from a population of 1.3 million patients. We then conducted a manual chart review in the electronic health record of all patients with a code for a bite to accurately determine which were from cats or dogs. Overall there were 750 patients with cat bites, 1,108 with dog bites, and approximately 117,000 patients with depression. Depression was found in 41.3% of patients with cat bites and 28.7% of those with dog bites. Furthermore, 85.5% of those with both cat bites and depression were women, compared to 64.5% of those with dog bites and depression. The probability of a woman being diagnosed with depression at some point in her life if she presented to our health system with a cat bite was 47.0%, compared to 24.2% of men presenting with a similar bite. The high proportion of depression in patients who had cat bites, especially among women, suggests that screening for depression could be appropriate in patients who present to a clinical provider with a cat bite. Additionally, while no causative link is known to explain this association, there is growing evidence to suggest that the relationship between cats and human mental illness, such as depression, warrants further investigation.
