OBJECTIVE It was the aim of this study to estimate effects of depression on permanent disability and death in a statutory health insurance population. METHODS Data from 128,001 clients were used with a mean follow up of 6.4 years. Excess risks were calculated with Cox regression models adjusted for age, gender, education and job classification. RESULTS Outpatient treatment for depression was associated with an elevated relative risk for permanent disability, but inpatient treatment even more so. Life table analysis suggests higher risks of early retirement for males who get ill early in life. Depression treated solely in an outpatient setting may be associated with lower mortality early in life, but this was only significant for women. CONCLUSIONS Outpatient treatment should include an emphasis on occupational functioning, but also a gender-specific approach is needed.

Alcohol use disorder-related sick leave and mortality: a cohort study

BackgroundAlcohol use disorders (AUDs) are associated with the highest all-cause mortality rates of all mental disorders. The majority of patients with AUDs never receive inpatient treatment for their AUD, and there is lack of data about their mortality risks despite their constituting the majority of those affected. Absenteeism from work (sick leave) due to an AUD likely signals worsening. In this study, we assessed whether AUD-related sick leave was associated with mortality in a cohort of workers in Germany.Methods128,001 workers with health insurance were followed for a mean of 6.4 years. We examined the associations between 1) AUD-related sick leave managed on an outpatient basis and 2) AUD-related psychiatric inpatient treatment, and mortality using survival analysis, and Cox proportional hazard regression models (separately by sex) adjusted for age, education, and job code classification. We also stratified analyses by sick leave related to three groups of alcohol-related conditions (all determined by International Classification of Diseases 9th ed. (ICD-9) codes): alcohol abuse and dependence; alcohol-induced mental disorder; and alcohol-induced medical conditions.ResultsOutpatient-managed AUD-related sick leave was significantly associated with higher mortality (hazard ratio (HR) 2.90 (95% Confidence interval (CI) 2.24-3.75) for men, HR 5.83 (CI 2.90-11.75) for women). The magnitude of the association was similar for receipt of AUD-related psychiatric inpatient treatment (HR 3.2 (CI 2.76-3.78) for men, HR 6.5 (CI 4.41-9.47) for women). Compared to those without the conditions, higher mortality was observed consistently for outpatients and inpatients across the three groups of alcohol-related conditions. Those with alcohol-related medical conditions who had AUD-related psychiatric inpatient treatment appeared to have the highest mortality.ConclusionsAlcohol use disorder-related sick leave as documented in health insurance records is associated with higher mortality. Such sick leave does not necessarily lead to any specific AUD treatment. Therefore, AUD-related sick leave might be used as a trigger for insurers to intervene by offering AUD treatment to patients to try to reduce their risk of death.

FC25-03 - Detrimental effects of anxiety disorders on ability to work associated with a protective effect on mortality in the middle decades of life

Aims Most available data about psychiatric mortality and invalidity concerns inpatients, although the majority of patients are treated as outpatients only. It was the aim of this study to estimate the effect of anxiety disorders on early retirement and premature death in the working population with special emphasis on outpatients. Methods 125.019 workes between age 16 and 58 were followed for an average of 6.4 years. Excess risks of death and permanent disability were calculated with multivariate Cox regression models. Results Outpatient and inpatient treatment for anxiety disorders (OR 1.40 resp. OR 2.10) were associated with higher risks of early retirement. Males generally were more often affected by this bad outcome than females. Further analysis showed decreased risks of premature death for outpatients with an anxiety disorder (OR 0.33). The effect tended to be most prominent during the middle decades of life and got smaller with older age, at which all-cause mortality approximated that of the control group. No significant effect on mortality could be shown for inpatients. Conclusions Patients with outpatient treatment for anxiety disorders have an elevated risk of permanent disability early in life, while all-cause mortality is lower. This beneficial effect can only be partly explained by different risk-taking behaviors. Different causes of death early in life and their connections with these disorders need to be discussed, too. Treatment should have a strong focus on preserving ability to work.
