Disparities in diabetes: The nexus of race, poverty, and place

OBJECTIVES We sought to determine the role of neighborhood poverty and racial composition on race disparities in diabetes prevalence. METHODS We used data from the 1999-2004 National Health and Nutrition Examination Survey and 2000 US Census to estimate the impact of individual race and poverty and neighborhood racial composition and poverty concentration on the odds of having diabetes. RESULTS We found a race-poverty-place gradient for diabetes prevalence for Blacks and poor Whites. The odds of having diabetes were higher for Blacks than for Whites. Individual poverty increased the odds of having diabetes for both Whites and Blacks. Living in a poor neighborhood increased the odds of having diabetes for Blacks and poor Whites. CONCLUSIONS To address race disparities in diabetes, policymakers should address problems created by concentrated poverty (e.g., lack of access to reasonably priced fruits and vegetables, recreational facilities, and health care services; high crime rates; and greater exposures to environmental toxins). Housing and development policies in urban areas should avoid creating high-poverty neighborhoods.

Interventions to Address Medical Conditions and Health-Risk Behaviors Among Persons With Serious Mental Illness: A Comprehensive Review

People with serious mental illness (SMI) have mortality rates 2 to 3 times higher than the overall US population, largely due to cardiovascular disease. The prevalence of cardiovascular risk factors such as obesity and diabetes mellitus and other conditions, such as HIV/AIDS, is heightened in this group. Based on the recommendations of a National Institute of Mental Health stakeholder meeting, we conducted a comprehensive review examining the strength of the evidence surrounding interventions to address major medical conditions and health-risk behaviors among persons with SMI. Peer-reviewed studies were identified using 4 major research databases. Randomized controlled trials and observational studies testing interventions to address medical conditions and risk behaviors among persons with schizophrenia and bipolar disorder between January 2000 and June 2014 were included. Information was abstracted from each study by 2 trained reviewers, who also rated study quality using a standard tool. Following individual study review, the quality of the evidence (high, medium, low) and the effectiveness of various interventions were synthesized. 108 studies were included. The majority of studies examined interventions to address overweight/obesity (n = 80). The strength of the evidence was high for 4 interventions: metformin and behavioral interventions had beneficial effects on weight loss; and bupropion and varenicline reduced tobacco smoking. The strength of the evidence was low for most other interventions reviewed. Future studies should test long-term interventions to cardiovascular risk factors and health-risk behaviors. In addition, future research should study implementation strategies to effectively translate efficacious interventions into real-world settings.

Cancer Incidence in a Sample of Maryland Residents With Serious Mental Illness

OBJECTIVE Persons with serious mental illness have an increased mortality rate and a higher burden of many medical conditions compared with persons without serious mental illness. Cancer risk in the population with serious mental illness is uncertain, and its incidence was examined by race, sex, and cancer site in a community-based cohort of adults with schizophrenia or bipolar disorder. METHODS The authors calculated standardized incidence ratios of total and site-specific cancers in a cohort of 3,317 Maryland Medicaid adult beneficiaries with schizophrenia or bipolar disorder followed from 1994 through 2004 for comparison with the U.S. population. RESULTS Total cancer incidence for adults with schizophrenia or bipolar disorder was 2.6 times higher in the cohort. Elevated risk was greatest for cancer of the lung. No differences in risk were found for African-American versus white Medicaid beneficiaries with serious mental illness. CONCLUSIONS These findings suggest that there is a heightened risk of cancer among adults with schizophrenia or bipolar disorder. Clinicians should promote appropriate cancer screening and work to reduce modifiable risk factors, such as smoking, among persons with serious mental illness.

Quality of medical care for persons with serious mental illness: A comprehensive review

OBJECTIVES Prior studies suggest variation in the quality of medical care for somatic conditions such as cardiovascular disease and diabetes provided to persons with SMI, but to date no comprehensive review of the literature has been conducted. The goals of this review were to summarize the prior research on quality of medical care for the United States population with SMI; identify potential sources of variation in quality of care; and identify priorities for future research. METHODS Peer-reviewed studies were identified by searching four major research databases and subsequent reference searches of retrieved articles. All studies assessing quality of care for cardiovascular disease, diabetes, dyslipidemia, and HIV/AIDs among persons with schizophrenia and bipolar disorder published between January 2000 and December 2013 were included. Quality indicators and information about the study population and setting were abstracted by two trained reviewers. RESULTS Quality of medical care in the population with SMI varied by study population, time period, and setting. Rates of guideline-concordant care tended to be higher among veterans and lower among Medicaid beneficiaries. In many study samples with SMI, rates of guideline adherence were considerably lower than estimated rates for the overall US population. CONCLUSIONS Future research should identify and address modifiable provider, insurer, and delivery system factors that contribute to poor quality of medical care among persons with SMI and examine whether adherence to clinical guidelines leads to improved health and disability outcomes in this vulnerable group.

Review of the evidence: prevalence of medical conditions in the United States population with serious mental illness

OBJECTIVE Persons with serious mental illness (SMI) have high rates of premature mortality from preventable medical conditions, but this group is underrepresented in epidemiologic surveys and we lack national estimates of the prevalence of conditions such as obesity and diabetes in this group. We performed a comprehensive review to synthesize estimates of the prevalence of 15 medical conditions among the population with SMI. METHOD We reviewed studies published in the peer-reviewed literature from January 2000 to August 2012. Studies were included if they assessed prevalence in a sample of 100 or more United States (US) adults with schizophrenia or bipolar disorder. RESULTS A total of 57 studies were included in the review. For most medical conditions, the prevalence estimates varied considerably. For example, estimates of obesity prevalence ranged from 26% to 55%. This variation appeared to be due to differences in measurement (e.g., self-report versus clinical measures) and underlying differences in study populations. Few studies assessed prevalence in representative, community samples of persons with SMI. CONCLUSIONS In many studies, the prevalence of medical conditions among the population with SMI was higher than among the overall US population. Screening for and monitoring of these conditions should be common practice in clinical settings serving persons with SMI.

Informed decision making about prostate cancer testing in predominantly immigrant black men: A randomized controlled trial

BackgroundDecision support interventions have been developed to help men clarify their values and make informed decisions about prostate cancer testing, but they seldom target high-risk black and immigrant men.PurposeThis study evaluated the efficacy of a decision support intervention focused on prostate cancer testing in a sample of predominantly immigrant black men.MethodsBlack men (N = 490) were randomized to tailored telephone education about prostate cancer testing or a control condition.ResultsPost-intervention, the intervention group had significantly greater knowledge, lower decision conflict, and greater likelihood of talking with their physician about prostate cancer testing than the control group. There were no significant intervention effects on prostate specific antigen testing, congruence between testing intention and behavior, or anxiety.ConclusionsA tailored telephone decision support intervention can promote informed decision making about prostate cancer testing in black and predominantly immigrant men without increasing testing or anxiety.

Schizophrenia and potentially preventable hospitalizations in the United States: a retrospective cross-sectional study

BackgroundPersons with schizophrenia may face barriers to high quality primary care due to communication difficulties, cognitive impairment, lack of social support, and fragmentation of healthcare delivery services. As a result, this group may be at high risk for ambulatory care sensitive (ACS) hospitalizations, defined as hospitalizations potentially preventable by timely primary care. The goal of this study was to determine if schizophrenia is associated with overall, acute, and chronic ACS hospitalizations in the United States (US).MethodsWe conducted a retrospective cross-sectional study. Hospitalization data for the US were obtained from the Nationwide Inpatient Sample for years 2003–2008. We examined 15,275,337 medical and surgical discharges for adults aged 18–64, 182,423 of which had a secondary diagnosis of schizophrenia. ACS hospitalizations were measured using the Agency for Healthcare Research and Quality’s Prevention Quality Indicators (PQIs). We developed logistic regression models to obtain nationally-weighted odds ratios (OR) for ACS hospitalizations, comparing those with and without a secondary diagnosis of schizophrenia after adjusting for patient, hospitalization, and hospital characteristics.ResultsSchizophrenia was associated with increased odds of hospitalization for acute ACS conditions (OR = 1.34; 95% CI: 1.31, 1.38), as well as for chronic ACS conditions characterized by short-term exacerbations. Schizophrenia was associated with decreased odds of hospitalization for diabetes mellitus long-term complications and diabetes-related lower extremity amputation, conditions characterized by long-term deterioration.ConclusionsAdditional research is needed to determine which individual and health systems factors contribute to the increased odds of hospitalization for acute PQIs in schizophrenia.

Screening for cardiovascular risk factors in adults with serious mental illness: a review of the evidence

BackgroundAdults with serious mental illness have a mortality rate two to three times higher than the overall US population, much of which is due to somatic conditions, especially cardiovascular disease. Given the disproportionately high prevalence of cardiovascular risk factors in the population with SMI, screening for these conditions is an important first step for timely diagnosis and appropriate treatment. This comprehensive literature review summarizes screening rates for cardiovascular risk factors in the population with serious mental illness.MethodsRelevant articles published between 2000 and 2013 were identified using the EMBASE, PsychInfo, PubMed, SCOPUS and Web of Science databases. We reviewed 10 studies measuring screening rates for obesity, diabetes, dyslipidemia, and hypertension in the population with serious mental illness. Two reviewers independently extracted information on screening rates, study population, and study setting.ResultsRates of screening varied considerably by time period, study population, and data source for all medical conditions. For example, rates of lipid testing for antipsychotic users ranged from 6% to 85%. For some conditions, rates of screening were consistently high. For example, screening rates for hypertension ranged from 79% - 88%.ConclusionsThere is considerable variation in screening of cardiovascular risk factors in the population with serious mental illness, with significant need for improvement in some study populations and settings. Implementation of standard screening protocols triggered by diagnosis of serious mental illness or antipsychotic use may be promising avenues for ensuring timely diagnosis and treatment of cardiovascular risk factors in this population.

Gun Policy and Serious Mental Illness: Priorities for Future Research and Policy

OBJECTIVE In response to recent mass shootings, policy makers have proposed multiple policies to prevent persons with serious mental illness from having guns. The political debate about these proposals is often uninformed by research. To address this gap, this review article summarizes the research related to gun restriction policies that focus on serious mental illness. METHODS Gun restriction policies were identified by researching the THOMAS legislative database, state legislative databases, prior review articles, and the news media. PubMed, PsycINFO, and Web of Science databases were searched for publications between 1970 and 2013 that addressed the relationship between serious mental illness and violence, the effectiveness of gun policies focused on serious mental illness, the potential for such policies to exacerbate negative public attitudes, and the potential for gun restriction policies to deter mental health treatment seeking. RESULTS Limited research suggests that federal law restricting gun possession by persons with serious mental illness may prevent gun violence from this population. Promotion of policies to prevent persons with serious mental illness from having guns does not seem to exacerbate negative public attitudes toward this group. Little is known about how restricting gun possession among persons with serious mental illness affects suicide risk or mental health treatment seeking. CONCLUSIONS Future studies should examine how gun restriction policies for serious mental illness affect suicide, how such policies are implemented by states, how persons with serious mental illness perceive policies that restrict their possession of guns, and how gun restriction policies influence mental health treatment seeking among persons with serious mental illness.
