Findings in this study are consistent with previous findings identifying excess mortality in a population with serious mental illness. The high rate of injury deaths, especially those due to psychotropic and other medications, should concern providers.
For decades, there have been reports of shorter life expectancy among those with mental illness, especially those with more serious psychiatric disorders. The purpose of this study was to compare the risk of mortality among Medicaid beneficiaries, aged 18-64 years, treated for mental illness to a comparable group who were not mentally ill and to the general population. The data used were from the Massachusetts Division of Medical Assistance and records of deaths from the Department of Public Health in Massachusetts. Individuals treated for both psychiatric illness and substance use disorders (dual diagnoses) were compared separately from those whose treatment was only for a psychiatric disorder. For all Medicaid beneficiaries, the most common causes of death were attributed to heart disease and cancer. When compared to the general population, adjusted odds ratios estimated death by injury to be twice as likely among the mentally ill when compared to the general population. Medicaid beneficiaries with dual diagnoses are 6-8 times more likely to die of injury, primarily poisoning, than their counterparts treated for medical conditions only.
Service fit, defined as consistency between mental health services judged needed and services received was measured for a random sample of service recipients in a public mental health system (N = 6588). A variant of small area analysis was used to measure the relationship between catchment area mortality rates from natural causes, suicide, and medicolegal causes and area fit scores for a variety of services. We tested the theory-based hypothesis that service fit would predict interarea variations in mortality better than simple measures of amount of service prescribed and received. We also tested the hypothesis that, controlling for relevant demographic and clinical factors, fit would be protective for mortality from all causes. Findings supported the first hypothesis. With respect to the second, service fit for only certain services was protective. Housing and clubhouses services were particularly protective, suggesting the importance of services providing social support.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
