Mental and somatic comorbidity of depression: a comprehensive cross-sectional analysis of 202 diagnosis groups using German nationwide ambulatory claims data.

ABSTRACT: BACKGROUND:Depression is frequently accompanied by other mental disorders and various somatic diseases; however, previous comorbidity studies often relied on self-reported data and have not simultaneously assessed the entire spectrum of mental and somatic diagnoses. The aim is to provide a complete picture of mental and somatic comorbidity of depression in routine outpatient care in a high income country with a relatively well equipped health care system. METHODS:Using ambulatory claims data covering 87% of the German population (age 15+), we designed a cross-sectional study by identifying persons diagnosed with mild, moderate and severe depression in 2017 (N?=?6.3 million) and a control group matched 4:1 on sex, 5-year age group and region of residence (N?=?25.2 million). Stratified by severity, we calculated the prevalence of 202 diagnosis groups included in the ICD-10 in persons with depression as compared to matched controls using prevalence ratios (PR). RESULTS:Nearly all mental disorders were at least twice as prevalent in persons with depression relative to controls, showing a dose-response relationship with depression severity. Irrespective of severity, the three most prevalent somatic comorbid diagnosis groups were 'other dorsopathies' (M50-M54), 'hypertensive diseases' (I10-I15) and 'metabolic disorders' (E70-E90), exhibiting PRs in moderate depression of 1.56, 1.23 and 1.33, respectively. Strong associations were revealed with diseases of the central nervous system (i.e. multiple sclerosis) and several neurological diseases, among them sleep disorders, migraine and epilepsy, most of them exhibiting at least 2- to 3-fold higher prevalences in depression relative to controls. Utilization of health care was higher among depression cases compared to controls. CONCLUSIONS:The present study based on data from nearly the complete adolescent and adult population in Germany comprehensively illustrates the comorbidity status of persons diagnosed with depression as coded in routine health care. Our study should contribute to increasing the awareness of the strong interconnection of depression with all other mental and the vast majority of somatic diseases. Our findings underscore clinical and health-economic relevance and the necessity of systematically addressing the high comorbidity of depression and somatic as well as other mental diseases through prevention, early identification and adequate management of depressive symptoms.

Project description:ImportancePsoriasis is a complex systemic disease with skin involvement, somatic comorbidity, and psychiatric illness (PI). Although this view of psoriasis is widely accepted, potential synergies within this triad of symptoms have not been adequately investigated.ObjectivesTo investigate the independent association of skin psoriasis and somatic comorbidity with the development of PI and to assess whether skin psoriasis and somatic comorbidity act synergistically to produce a risk of PI that is greater than the additive associations.Design, setting, and participantsParticipants were enrolled between January 2005 and December 2010, in this retrospective matched case-control study using secondary (ie, administrative), population-based registry data from Swedish patients in routine clinical care. The dates of analysis were March 2017 to December 2019. Participants were patients with skin psoriasis and control participants without psoriasis matched on age, sex, and municipality, who were all free of preexisting PI.ExposuresPresence of skin psoriasis and somatic comorbidity (captured through the Charlson Comorbidity Index and the Elixhauser Comorbidity Index).Main outcomes and measuresRisk of PI onset (composite of depression, anxiety, and suicidality) is shown using Kaplan-Meier curves stratified by the presence of skin psoriasis and somatic comorbidity. Adjusted associations of skin psoriasis and somatic comorbidity with the development of PI were analyzed using Cox proportional hazards regression models, including interactions to assess synergistic associations. The 3 components of PI were also assessed individually.ResultsA total of 93 239 patients with skin psoriasis (mean [SD] age, 54 [17] years; 47 475 men [51%]) and 1 387 495 control participants (mean [SD] age, 54 [16] years; 702 332 men [51%]) were included in the study. As expected, patients with skin psoriasis were more likely to have somatic comorbidity and PI than control participants. Compared with those without skin psoriasis or somatic comorbidity, patients with psoriasis without somatic comorbidity had a 1.32 times higher risk of PI onset (hazard ratio [HR], 1.32; 95% CI, 1.27-1.36; P < .001), whereas patients with psoriasis with somatic comorbidity had a 2.56 times higher risk of PI onset (HR, 2.56; 95% CI, 2.46-2.66; P < .001). No synergistic associations of skin psoriasis and somatic comorbidity with the development of PI were found (HR, 0.93; 95% CI, 0.81-1.04; P = .21).Conclusions and relevanceThis study found that somatic comorbidity appeared to alter PI onset even more than skin psoriasis. The observed association of skin psoriasis and somatic comorbidity with the development of PI reinforces the need for proactive, holistic treatment of patients with psoriasis.

Project description:ImportanceBecause hearing loss is highly prevalent and treatable, determining its association with morbidity has major public health implications for disease prevention and the maintenance of health in adults with hearing loss.ObjectiveTo investigate the association between the diagnosis of incident hearing loss and medical comorbidities in adults 50 years or older.Design, setting, and participantsRetrospective, propensity-matched cohort study using administrative claims data from commercially insured and Medicare Advantage members in a geographically diverse US health plan. Adults 50 years or older with claims for services rendered from January 1, 2000, to December 31, 2016, were observed for 2 (n = 154 414), 5 (n = 44 852), and 10 (n = 4728) years. This research was conceptualized and data were analyzed between September 2016 and November 2017.ExposuresA claim for incident hearing loss is defined as 2 claims for hearing loss within 2 consecutive years without evidence of hearing device use, excluding claims for sudden hearing loss or hearing loss secondary to medical conditions.Main outcomes and measuresIncident claims for dementia, depression, accidental falls, nonvertebral fractures, acute myocardial infarction, and stroke.ResultsAfter cohort matching, 48% of participants were women (n = 74 464), 61% were white (n = 93 442), and 31% (n = 48 056) were Medicare Advantage insured, with a mean (SD) age of 64 (10) years. In a multivariate-adjusted modified Poisson regression with robust standard errors, relative associations were strongest for dementia (relative risk at 5 years, 1.50; 95% CI, 1.38-1.64) and depression (relative risk at 5 years, 1.41; 95% CI, 1.26-1.58). The absolute risk of all outcomes was greater in persons with hearing loss than in those without hearing loss at all times, with the greatest risk difference observed at 10 years for all outcomes. The 10-year risk attributable to hearing loss was 3.20 per 100 persons (95% CI, 1.76-4.63) for dementia, 3.57 per 100 persons (95% CI, 1.67-5.47) for falls, and 6.88 per 100 persons (95% CI, 4.62-9.14) for depression.Conclusions and relevanceIn this large observational study using administrative claims data, incident untreated hearing loss was associated with greater incident morbidity than no hearing loss across a range of health conditions. Future studies are needed to elucidate the mechanisms underlying these associations and to determine if treatment for hearing loss could reduce the risk of comorbidity.
