Excess mortality in persons with severe mental disorders (SMD) is a major public health challenge that warrants action. The number and scope of truly tested interventions in this area remain limited, and strategies for implementation and scaling up of programmes with a strong evidence base are scarce. Furthermore, the majority of available interventions focus on a single or an otherwise limited number of risk factors. Here we present a multilevel model highlighting risk factors for excess mortality in persons with SMD at the individual, health system and socio-environmental levels. Informed by that model, we describe a comprehensive framework that may be useful for designing, implementing and evaluating interventions and programmes to reduce excess mortality in persons with SMD. This framework includes individual-focused, health system-focused, and community level and policy-focused interventions. Incorporating lessons learned from the multilevel model of risk and the comprehensive intervention framework, we identify priorities for clinical practice, policy and research agendas.

Schizophrenia is often referred to as one of the most severe mental disorders, primarily because of the very high mortality rates of those with the disorder. This article reviews the literature on excess early mortality in persons with schizophrenia and suggests reasons for the high mortality as well as possible ways to reduce it. Persons with schizophrenia have an exceptionally short life expectancy. High mortality is found in all age groups, resulting in a life expectancy of approximately 20 years below that of the general population. Evidence suggests that persons with schizophrenia may not have seen the same improvement in life expectancy as the general population during the past decades. Thus, the mortality gap not only persists but may actually have increased. The most urgent research agenda concerns primary candidates for modifiable risk factors contributing to this excess mortality, i.e., side effects of treatment and lifestyle factors, as well as sufficient prevention and treatment of physical comorbidity.

BackgroundExcess mortality among patients with severe mental disorders has not previously been investigated in detail in large complete national populations.ObjectiveTo investigate the excess mortality in different diagnostic categories due to suicide and other external causes of death, and due to specific causes in connection with diseases and medical conditions.MethodsIn longitudinal national psychiatric case registers from Denmark, Finland, and Sweden, a cohort of 270,770 recent-onset patients, who at least once during the period 2000 to 2006 were admitted due to a psychiatric disorder, were followed until death or the end of 2006. They were followed for 912,279 person years, and 28,088 deaths were analyzed. Life expectancy and standardized cause-specific mortality rates were estimated in each diagnostic group in all three countries.ResultsThe life expectancy was generally approximately 15 years shorter for women and 20 years shorter for men, compared to the general population. Mortality due to diseases and medical conditions was increased two- to three-fold, while excess mortality from external causes ranged from three- to 77-fold. Mortality due to diseases and medical conditions was generally lowest in patients with affective disorders and highest in patients with substance abuse and personality disorders, while mortality due to suicide was highest in patients with affective disorders and personality disorders, and mortality due to other external causes was highest in patients with substance abuse.ConclusionsThese alarming figures call for action in order to prevent the high mortality.

BackgroundPeople with mental disorders evince excess mortality due to natural and unnatural deaths. The relative life expectancy of people with mental disorders is a proxy measure of effectiveness of social policy and health service provision.AimsTo evaluate trends in health outcomes of people with serious mental disorders.MethodWe examined nationwide 5-year consecutive cohorts of people admitted to hospital for mental disorders in Denmark, Finland and Sweden in 1987–2006. In each country the risk population was identified from hospital discharge registers and mortality data were retrieved from cause-of-death registers. The main outcome measure was life expectancy at age 15 years.ResultsPeople admitted to hospital for a mental disorder had a two- to threefold higher mortality than the general population in all three countries studied. This gap in life expectancy was more pronounced for men than for women. The gap decreased between 1987 and 2006 in these countries, especially for women. The notable exception was Swedish men with mental disorders. In spite of the positive general trend, men with mental disorders still live 20 years less, and women 15 years less, than the general population.ConclusionsDuring the era of deinstitutionalisation the life expectancy gap for people with mental disorders has somewhat diminished in the three Nordic countries. Our results support further development of the Nordic welfare state model, i.e. tax-funded community-based public services and social protection. Health promotion actions, improved access to healthcare and prevention of suicides and violence are needed to further reduce the life expectancy gap.

IMPORTANCE Individuals with mental disorders often develop comorbidity over time. Past studies of comorbidity have often restricted analyses to a subset of disorders and few studies have provided absolute risks of later comorbidity. OBJECTIVES To undertake a comprehensive study of comorbidity within mental disorders, by providing temporally ordered age-and sex-specific pairwise estimates between the major groups of mental disorders, and to develop an interactive website to visualize all results and guide future research and clinical practice.

Schizophrenia is associated with a substantially higher mortality and curtailed life expectancy partly caused by modifiable risk factors.
