Effect of care setting on evidence-based depression treatment for veterans with COPD and comorbid depression.

ABSTRACT: BACKGROUND: Patients with chronic obstructive pulmonary disorder (COPD) frequently have co-occurring depressive disorders and are often seen in multiple-care settings. Existing research does not assess the impact of care setting on delivery of evidence-based depression care for these patients. OBJECTIVE: To examine the prevalence of guideline-concordant depression treatment among these co-morbid patients, and to examine whether the likelihood of receiving guideline-concordant treatment differed by care setting. DESIGN: Retrospective cohort study. PATIENTS: A total of 5,517 veterans with COPD that experienced a new treatment episode for major depressive disorder. MEASUREMENTS AND MAIN RESULTS: Concordance with VA treatment guidelines for depression; multivariate analyses of the relationship between guideline-concordant depression treatment and care setting. More than two-thirds of the sample was over age 65 and 97% were male. Only 50.6% of patients had guideline-concordant antidepressant coverage (defined by the VA). Fewer than 17% of patients received guideline recommended follow-up (> or = 3 outpatient visits during the acute phase), and only 9.9% of the cohort received both guideline-concordant antidepressant coverage and follow-up visits. Being seen in a mental health clinic during the acute phase was associated with a 7-fold increase in the odds of receiving guideline-concordant care compared to primary care only. Patients seen in pulmonary care settings were also more likely to receive guideline-concordant care compared to primary care only. CONCLUSIONS: Most VA patients with COPD and an acute depressive episode receive suboptimal depression management. Improvements in depression treatment may be particularly important for those patients seen exclusively in primary care settings.

Project description:BackgroundPsychiatric comorbidities may complicate depression treatment by being associated with increased role impairments. However, depression symptom severity might account for these associations. Understanding the independent associations of depression severity and comorbidity with impairments could help in treatment planning. This is especially true for depressed Veterans, who have high psychiatric comorbidity rates.Methods2,610 Veterans beginning major depression treatment at the Veterans Health Administration (VHA) were administered a baseline self-report survey that screened for diverse psychiatric comorbidities and assessed depression severity and role impairments. Logistic and generalized linear regression models estimated univariable and multivariable associations of depression severity and comorbidities with impairments. Population attributable risk proportions (PARPs) estimated the relative importance of depression severity and comorbidities in accounting for role impairments.ResultsNearly all patients (97.8%) screened positive for at least one comorbidity and half (49.8%) for 4+ comorbidities. The most common positive screens were for generalized anxiety disorder (80.2%), posttraumatic stress disorder (77.9%), and panic/phobia (77.4%). Depression severity and comorbidities were significantly and additively associated with impairments in multivariable models. Associations were attenuated much less for depression severity than for comorbidities in multivariable versus univariable models. PARPs indicated that 15-60% of role impairments were attributable to depression severity and 5-32% to comorbidities.LimitationsThe screening scales could have over-estimated comorbidity prevalence. The cross-sectional observational design cannot determine either temporal or causal priorities.ConclusionsAlthough positive screens for psychiatric comorbidity are pervasive among depressed VHA patients, depression severity accounts for most of the associations of these comorbidities with role impairments.

Project description:ObjectivePeripheral artery disease (PAD) is an increasing health concern with rising incidence globally. Previous studies have shown an association between PAD incidence and depression. The objective of the study was to determine the association of comorbid depression with PAD outcomes (amputation and all-cause mortality rates) in veterans.MethodsAn observational retrospective cohort of 155,647 patients with incident PAD (2003-2014) from nationwide U.S. Veterans Health Administration hospitals was conducted using the national Veterans Affairs Corporate Data Warehouse. Depression was measured using concurrent International Classification of Diseases, Ninth Revision diagnosis codes 6 months before or after PAD diagnosis. The main outcomes were incident major amputation and all-cause mortality. Crude associations were assessed with Kaplan-Meier plots. The effects of depression adjusted for covariates were analyzed using Cox proportional hazards models.ResultsDepression was present in 16% of the cohort, with the occurrence of 9517 amputations and 63,287 deaths (median follow-up, 5.9 years). Unadjusted hazard ratios (HRs) of comorbid depression for amputations and all-cause mortality were 1.32 (95% confidence interval [CI], 1.25-1.39) and 1.02 (95% CI, 0.99-1.04), respectively. After adjustment for covariates in Cox regression models, a diagnosis of comorbid depression at the time of PAD diagnosis was associated with a 13% higher amputation (HR, 1.13; 95% CI, 1.07-1.19) and 17% higher mortality (HR, 1.17; 95% CI, 1.14-1.20) risk compared with patients with no depression. On stratification by use of antidepressants, depressed patients not taking antidepressants had a 42% higher risk of amputation (HR, 1.42; 95% CI, 1.27-1.58) compared with those without depression. Patients taking antidepressants for depression still had increased risk of amputation but only 10% higher compared with those without depression (HR, 1.10; 95% CI, 1.03-1.17). Interestingly, patients taking antidepressants for other indications also had a higher risk of amputation compared with those not having depression or not taking antidepressants (HR, 1.08; 95% CI, 1.03-1.14). Having any diagnosis of depression or the need for antidepressants increased the mortality risk by 18% to 25% in the PAD cohort compared with those without depression and not taking antidepressants for any other indication.ConclusionsPAD patients with comorbid depression have a significantly higher risk of amputation and mortality than PAD patients without depression. Furthermore, untreated depression was associated with an increased amputation risk in the PAD population, more so than depression or other mental illness being treated by antidepressants. The underlying mechanisms for causality, if any, remain to be determined. The association of antidepressant treatment use with amputation risk should prompt further investigations into possible mechanistic links between untreated depression and vascular dysfunction.
