Abstract

ABSTRACT

Individuals with mental illness continue to experience significant disparities in quality of care compared with the general population. Approximately 60 million Americans live with a mental health disorder, and this population experiences morbidity and mortality rates approximately 2 to 6 times higher than those without mental illness. These individuals typically have a shortened life expectancy of 10–20 years. This review examines the impact of healthcare disparities and inadequately treated medical comorbidities on health outcomes among individuals with mental illness. Persistent barriers, including stigma, limited access to care, inadequate health literacy, and refusal of treatment, contribute to these disparities. Additionally, poor coordination between mental health and medical care systems may delay diagnosis and management of chronic medical conditions. Collaborative care models that integrate psychiatric and medical treatment may improve management of comorbid conditions and reduce adverse health outcomes.

Limitations of the reviewed evidence include small sample sizes, limited recent data, potential bias related to stigma, and uncontrolled variables. Strengths include the reliability of sources and applicability across multiple psychiatric diagnoses. Future research should evaluate the impact of medical care delivery within psychiatric facilities, the effectiveness of collaborative treatment teams, outcomes associated with adequately treated mental illness, and the role of treatment adherence in improving medical outcomes. Improved coordination between mental health and medical providers may help address gaps in care and support earlier identification and management of chronic disease. Continued investigation and targeted interventions are essential to improving care, reducing stigma, and decreasing morbidity and mortality among individuals with mental illness.
