Process of care and outcome after acute myocardial infarction for patients with mental illness in the VA health care system: are there disparities?

Alzheimer's Disease and Alzheimer's Disease-Related Dementias in Older African American and White Veterans

BACKGROUND

Racial disparity in the epidemiology of Alzheimer's disease and Alzheimer's disease-related dementias (AD/ADRD) has been reported. However, less is known about this disparity among Veterans.

OBJECTIVE

To estimate the racial disparity in AD/ADRD among the Veterans.

METHODS

Of the 5,413,418 Veterans≥65 years receiving care at the Veterans Health Administration (1999-2016), 4,045,269 were free of prevalent AD/ADRD, schizophrenia, or bipolar disorder at baseline. Of these, 432,469 were African American. Race was self-identified and incident AD/ADRD during 20 (median 6.7) years of follow-up was ascertained using International Classification of Diseases codes.

RESULTS

Patients had a mean age of 70.4 (±6.6) years and 97.8% were men. Age-sex-adjusted incidence of AD/ADRD per 1,000 person-year was 19.3 and 10.8 for African American and white Veterans, respectively (age-sex-adjusted hazard ratio associated with African American race, 1.77; 95% confidence interval, 1.75-1.79; p < 0.0001). This association remained essentially unchanged after multivariable adjustment (hazard ratio, 1.67; 95% confidence interval, 1.65-1.69; p < 0.0001). Among the key baseline characteristics that were significant predictors of AD/ADRD in both races, stroke was a significantly stronger predictor among African Americans, and Hispanic ethnicity and depression among whites (p-value for all interaction,<0.0001).

CONCLUSION

The findings of a higher incidence of AD/ADRD among African American Veterans is consistent with the findings in the general population reported in the literature, although the overall incidence appears to be lower than that in the general population. Future studies need to examine this disparity in incidence as well as the between-race heterogeneity in AD/ADRD risk.

Mental health disorders among patients with acute myocardial infarction in the United States

OBJECTIVE

To assess the prevalence, temporal trends and sex- and racial/ethnic differences in the burden of mental health disorders (MHD) and outcomes among patients with myocardial infarction (MI) in the United States.

METHODS

Using the National Inpatient Sample Database, we evaluated a contemporary cohort of patients hospitalized for acute MI in the United States over 10 years period from 2008 to 2017. We used multivariable logistic regression analysis for in-hospital outcomes, yearly trends and estimated annual percent change (APC) in odds of MHD among MI patients.

RESULTS

We included a total sample of 6,117,804 hospitalizations for MI (ST elevation MI in 30.4%), with a mean age of 67.2 ​± ​0.04 years and 39% females. Major depression (6.2%) and anxiety disorders (6.0%) were the most common MHD, followed by bipolar disorder (0.9%), schizophrenia/psychotic disorders (0.8%) and post-traumatic stress disorder (PTSD) (0.3%). Between 2008 and 2017, the prevalences significantly increased for major depression (4.7%-7.4%, APC +6.2%, p ​< ​.001), anxiety disorders (3.2%-8.9%, APC +13.5%, p ​< ​.001), PTSD (0.2%-0.6%, +12.5%, p ​< ​.001) and bipolar disorder (0.7%-1.0%, APC +4.0%, p ​< ​.001). Significant sex- and racial/ethnic-differences were also noted. Major depression, bipolar disorder or schizophrenia/psychotic disorders were associated with a lower likelihood of coronary revascularization.

CONCLUSION

MHD are common among patients with acute MI and there was a concerning increase in the prevalence of major depression, bipolar disorder, anxiety disorders and PTSD over this 10-year period. Focused mental health interventions are warranted to address the increasing burden of comorbid MHD among acute MI.

Mortality, Revascularization, and Cardioprotective Pharmacotherapy After Acute Coronary Syndrome in Patients With Psychotic Disorders: A Population-Based Cohort Study

Ischemic heart disease is the leading cause of mortality in psychotic disorders. There is a paucity of research comprehensively evaluating short-term mortality, cardiovascular complications, and treatment inequality after cardiac events in patients with psychotic disorders. This population-based cohort study examined 30-day and 1-year all-cause mortality, cardiovascular complication rates, 30-day and 1-year receipt of invasive cardiac procedures, and 90-day post-discharge cardioprotective medication treatment following admission for first-recorded acute coronary syndrome (ACS) among patients with psychotic disorders (n = 703) compared with patients without psychotic disorders (n = 66 989) between January 2006 and December 2016 in Hong Kong (HK). Study data were retrieved from territory-wide medical record database of public healthcare services to 7.5 million HK residents. Multivariate regression analyses (ORs and 95% CIs), adjusting for demographics and medical comorbidities, were conducted to evaluate associations between psychotic disorders and post-ACS outcomes. Our results showed that patients with psychotic disorders had higher 30-day (OR: 1.99 [95% CI: 1.65-2.39]) and 1-year (2.13 [1.79-2.54]) mortality, and cardiovascular complication rates (1.20 [1.02-1.41]), lower receipt of cardiac catheterization (30-d: 0.54 [0.43-0.68]; 1-y: 0.46 [0.38-0.56]), percutaneous coronary intervention (30-d: 0.55 [0.44-0.70]; 1-y: 0.52 [0.42-0.63]) and reduced β-blockers (0.81 [0.68-0.97]), statins (0.54 [0.44-0.66]), and clopidogrel prescriptions (0.66 [0.55-0.80]). Associations between psychotic disorder and increased mortality remained significant even after complications and treatment receipt were additionally adjusted. Our findings indicate that psychotic disorders are associated with increased risks of short-term post-ACS mortality, cardiovascular complications, and inferior treatment. Excess mortality is not substantially explained by treatment inequality. Further investigation is warranted to clarify factors for suboptimal cardiac-care and elevated mortality in psychotic disorders to enhance post-ACS outcome.

Effects of Mental Health Disorders on Nursing Home Residents' Nine-Month Pain Trajectories

OBJECTIVE

To determine the key classes of nursing home residents' nine-month pain trajectories, the influence of residents' mental health disorders on membership in these classes, and nine-month health-related outcomes associated with pain trajectory class membership.

METHODS

Four times over a nine-month period, the MDS 3.0 resident assessment instrument was used to record the demographic characteristics, mental health disorder diagnoses, pain characteristics, and health and functioning outcomes of 2,539 Department of Veterans Affairs Community Living Center (VA CLC) residents. Growth mixture modeling was used to estimate the key classes of residents' nine-month pain trajectories, the influence of residents' mental health disorders on their pain trajectory class membership, and the associations of class membership with residents' health and functioning outcomes at nine-month follow-up.

RESULTS

Four-class solutions best described nursing home residents' nine-month trajectories of pain frequency, severity, and interference. Residents with dementia and severe mental illness diagnoses were less likely, and those with depressive disorder, PTSD, and substance use disorder diagnoses more likely, to belong to adverse nine-month pain trajectory classes. Membership in adverse pain frequency and pain severity trajectory classes, and in trajectory classes characterized by initially high but steeply declining pain interference, portended more depressive symptoms but better cognitive and physical functioning at nine-month follow-up.

CONCLUSIONS

Nursing home residents' mental health disorder diagnoses help predict their subsequent pain frequency, severity, and interference trajectories. This may be clinically useful information for improving pain assessment and treatment approaches for nursing home residents.

Mental health disorder, pain, and pain treatment among long-term care residents: Evidence from the Minimum Data Set 3.0

Objective: This study evaluated: (a) associations between long-term care residents' mental health disorder diagnoses and their pain self-reports and pain treatments, and (b) the extent to which communication, cognitive, and physical functioning problems help explain disparities in the pain and pain treatments of long-term care residents with and without mental health disorders. Method: Minimum Data Set 3.0 records of 8,300 residents of Department of Veterans Affairs Community Living Centers were used to determine statistically unadjusted and adjusted cross-sectional associations between residents' mental health diagnoses and their pain and pain treatments. Results: Residents diagnosed with dementia and serious mental illness (SMI) were less likely, and those diagnosed with depressive disorder, post-traumatic stress disorder (PTSD), and substance use disorder (SUD) were more likely, to report recent, severe, and debilitating pain. Among residents affirming recent pain, those with dementia or SMI diagnoses were twice as likely to obtain no treatment for their pain and significantly less likely to receive as-needed pain medication and non-pharmacological pain treatments than were other residents. Those with either depressive disorder or PTSD were more likely, and those with SUD less likely, to obtain scheduled pain medication. In general, these associations remained even after statistically adjusting for residents' demographic characteristics, other mental health disorder diagnoses, and functioning. Conclusion: Long-term care residents with mental health disorders experience disparities in pain and pain treatment that are not well-explained by their functioning deficits. They may benefit from more frequent, thorough pain assessments and from more varied and closely tailored pain treatment approaches.

Acute Myocardial Infarction in Severe Mental Illness: Prevalence, Clinical Outcomes, and Process of Care in U.S. Hospitalizations

BACKGROUND

Severe mental illness (SMI) is associated with increased cardiovascular mortality. We sought to examine the prevalence, clinical outcomes, and management strategy of patients with SMI presenting with acute myocardial infarction (AMI).

METHODS

All AMI hospitalizations from the National Inpatient Sample were included, stratified by mental health status into 5 groups: no SMI, schizophrenia, other non-organic psychoses (ONOP), bipolar disorder, and major depression. Regression analyses were performed to assess the association (adjusted odds ratios [ORs], P ≤ 0.001 for all outcomes) between SMI subtypes and clinical outcomes.

RESULTS

Of 6,968,777 AMI hospitalizations between 2004 and 2014, 439,544 patients (6.5%) had an SMI diagnosis. Although patients with schizophrenia and ONOP experienced higher crude rates of in-hospital mortality and stroke compared with those without SMI, only schizophrenic patients were at increased odds of mortality (OR, 1.10; 95% confidence interval [CI], 1.04-1.16), whereas ONOP was the only group at increased odds of stroke (OR, 1.53; 95% CI, 1.42-1.65) after multivariate adjustment. Patients with ONOP were the only group associated with increased odds of in-hospital bleeding compared with those without SMI (OR, 1.11; 95% CI, 1.04-1.17). All those with SMI subtypes were less likely to receive coronary angiography and percutaneous coronary intervention, with the schizophrenia group being at least odds of either procedure (OR, 0.46; 95% CI, 0.45-0.48 and OR, 0.57; 95% CI, 0.55-0.59, respectively).

CONCLUSION

Schizophrenia and ONOP are the only SMI subtypes associated with adverse clinical outcomes after AMI. However, all patients with SMI were less likely to receive invasive management for AMI, with female gender and schizophrenia diagnosis being the strongest predictors of conservative management. A multidisciplinary approach between psychiatrists and cardiologists could improve the outcomes of this high-risk population.

An Exploration of Residents' Implicit Biases Towards Depression-a Pilot Study

BACKGROUND

Implicit attitudes are outside of conscious awareness and are thought to affect automatic responses outside of one's deliberate control, with the potential to impact physician-patient relationships.

OBJECTIVE

To measure the nature and extent of implicit biases towards depression in internal medicine and psychiatry residents.

DESIGN

Descriptive and comparative study.

PARTICIPANTS

Fifty-one residents from three internal medicine programs and 35 residents from three psychiatry programs located in two states.

INTERVENTIONS

Participants were sent a link to voluntarily participate in four online implicit association tests. Residents' identities were anonymous.

MAIN MEASURES

Four implicit association tests to measure the association of (1) attitude (good/bad), (2) permanence, (3) controllability, and (4) etiology with depression/physical illness.

KEY RESULTS

Internal medicine residents demonstrated a significant association between depression and negative attitudes (t(38) = 6.01, p < .001, Cohen's d = .95), uncontrollability (t(35) = 4.80, p < .001, Cohen's d = .79), temporariness (t(37) = 2.94, p = .006, Cohen's d = .48), and a psychologic etiology (t(1) = 6.91, p < .001, Cohen's d = 1.24). Psychiatry residents only demonstrated an association between depression and a psychologic etiology (t(2) = 4.79, p < .001, Cohen's d = 4.5). When comparing the two specialties, internal medicine and psychiatry differed on two of the IATs. Internal medicine residents were more likely to associate negative attitudes with depression than psychiatry residents (t(63) = 4.66, p < .001, Cohen's d = 1.18) and to associate depression with being uncontrollable (t(57) = 3.17, p = .002, Cohen's d = .81).

CONCLUSIONS

Internal medicine residents demonstrated biases in their attitudes towards depression and significantly differed in some areas from psychiatry residents. This pilot study needs to be replicated to confirm our findings and further work needs to be done to determine the effect of these attitudes on the provision of clinical care.

Increased long-term mortality after myocardial infarction in patients with schizophrenia

BACKGROUND

Ischemic heart disease increases mortality in patients with schizophrenia. This nationwide study explored short-term and long-term mortality rates in patients with schizophrenia experiencing myocardial infarction (MI) compared to controls from the general population experiencing MI, as well as patients with schizophrenia and people from the general population not experiencing MI.

METHOD

A Danish nationwide cohort study including incident patients diagnosed with schizophrenia between 1980 and 2015, matched 1:5 on year of birth and gender to controls from the general population. Primary outcome was all-cause mortality. Data were analysed utilizing Cox regression models, Kaplan-Meier estimates and standardized mortality ratios (SMR).

RESULTS

Patients with schizophrenia experiencing MI had an increased mortality rate (Hazard rate ratio (HR) 9.94, 95%CI(8.71-11.35)), as well as schizophrenia controls (HR 4.50, 95%CI(4.36-4.64)) and MI controls (HR 3.27, 95%CI(3.03-3.52)) with controls not experiencing MI serving as reference in a model adjusted for age at entry, gender and calendar year. No difference in 30-day mortality was observed between groups experiencing MI, but increased mortality rates were shown in patients with schizophrenia at 1-year and 5-year follow-up. Trends in SMR declined in MI controls, while patients with schizophrenia showed an unchanged SMR over time.

CONCLUSIONS

Patients with schizophrenia have not experienced a decline in mortality rate following MI compared to the general population in long-term follow-up. This finding highlights the need for research in MI follow-up care for patients with schizophrenia.

Internal Medicine Residents' Attitudes Toward Simulated Depressed Cardiac Patients During an Objective Structured Clinical Examination: A Randomized Study

BACKGROUND

Physician biases toward mental conditions such as depression have been shown to adversely affect medical outcomes.

OBJECTIVE

To explore the relationship between residents' explicit bias toward depressed patients and their clinical skills on a cardiac case during an objective structured clinical exam (OSCE).

DESIGN

Prospective parallel randomized controlled study.

PARTICIPANTS

One hundred eighty-five internal medicine residents from three residency programs in two states.

INTERVENTION

During October-November 2015, residents were randomized to either a depressed or non-depressed standardized patient (SP) presenting with acute chest pain.

MAIN MEASURES

The Medical Condition Regard Scale (MCRS) assessed residents' explicit bias toward patients with depression. Their clinical skills (history-taking, physical examination, patient counseling, patient-physician interaction (PPI), differential diagnosis, and workup plan) and facial expressions were rated during an OSCE.

KEY RESULTS

No significant relationships were found between resident explicit bias and clinical skill measurements. Residents who examined the depressed SP scored lower, on average, on history-taking (t [183] = -2.77, p < 0.01, Cohen's d = 0.41) and higher on PPI (t [183] = 2.24, p < 0.05, Cohen's d = 0.33) than residents examining the non-depressed SP. There were no differences, on average, between stations on physical examination, counseling, correct diagnosis, workup plan, or overall SP satisfaction. Facial recognition software demonstrated that residents with a non-depressed SP had more neutral expressions than depressed-SP residents (t [133] = -2.46, p < 0.05, Cohen's d = 0.46), and residents with a depressed SP had more disgusted expressions than non-depressed-SP residents (t [83.52] = 2.10, p < 0.05, Cohen's d = 0.28).

CONCLUSIONS

Extrinsic bias did not predict OSCE performance in this study. Some differences were noted in the OSCE performance between the two stations. Further study is needed to examine the effects of patient mental health conditions on physician examination procedures, diagnostic behaviors, and patient outcomes.

Treatment following myocardial infarction in patients with schizophrenia

BACKGROUND

A correlation between excess mortality from myocardial infarctions (MI) and schizophrenia has already been established. What remains unclear is whether the initial communication between the treating doctor and the corresponding patient contributes to this excess mortality.

AIM

The aim of this study is to investigate whether a patient with schizophrenia receives the same offers for examination and treatment following a MI compared to a psychiatric healthy control (PHC).

METHODS

This cohort study includes patients diagnosed with schizophrenia at the time of their first MI (n = 47) in the years between 1995-2015 matched 1:2 to psychiatric healthy MI patients on gender, age and year of first MI. All existing hospital files for the 141 patients were thoroughly reviewed and the number of offered and accepted examinations and treatments were extracted for comparisons between the two groups.

RESULTS

In general patients with schizophrenia were less likely to be offered and accept examination and at the same time be offered and accept treatment as compared to PHCs (p<0.01). In addition, there was a statistical trend towards patients with schizophrenia being more likely to decline examination (p = 0.10) and decline treatment (p = 0.09) compared to PHCs, while being offered examination and being offered treatment both contributed statistically insignificantly to the overall discrepancy between the two patient groups.

CONCLUSIONS

Being diagnosed with schizophrenia limits the treatment received following a first MI compared to PHCs. However, we are unable to pinpoint, whether Physician bias, patient's unwillingness to receive health care or both contribute to the excess mortality seen in these comorbid patients.

Severe Mental Illness and Clinical Outcome After Primary Percutaneous Coronary Intervention

The mechanisms behind the increased mortality in patients with acute myocardial infarction and co-existing severe mental illness (SMI) compared with non-SMI patients remain unclear. We studied 12,102 patients with ST-elevation myocardial infarction treated with primary percutaneous coronary intervention, of whom 457 had SMI. The primary outcome was major adverse cardiac events (death, myocardial infarction, target vessel revascularization) at 30 days, 1 year, 2 years, and maximum follow-up. Patients with SMI were younger, more often women, had higher prevalence of active smoking and diabetes, and had a longer duration of symptoms than patients without SMI. There were no substantial differences in the in-hospital treatment of patients with and without SMI. Fewer SMI patients were treated with the recommended medications during follow up; however, the absolute differences were modest. Compared with non-SMI patients, the cumulative risks of major adverse cardiac events after 1 year, 2 years, and maximum follow-up were higher among SMI patients [hazard ratio 1.27 (1.02 to 1.57), hazard ratio 1.32 (1.09 to 1.60), and hazard ratio 1.43 (1.25 to 1.65), respectively]. Even after adjustment for differences in baseline characteristics, the differences in outcome persisted. In conclusion, compared with patients without SMI, primary percutaneous coronary intervention treated patients with SMI had a worse baseline risk profile. No differences in in-hospital treatments were found. Although the absolute differences were small, SMI patients were less likely to receive recommended medical treatment during follow up and they face a worse prognosis, even after adjustment for differences in risk profile. This indicates that SMI per se is likely to have an adverse effect on the prognosis following ST-elevation myocardial infarction.

Stroke survivors with severe mental illness: Are they at-risk for increased non-psychiatric hospitalizations?

BACKGROUND

This study examined outcomes for two groups of stroke survivors treated in Veteran Health Administration (VHA) hospitals, those with a severe mental illness (SMI) and those without prior psychiatric diagnoses, to examine risk of non-psychiatric medical hospitalizations over five years after initial stroke.

METHODS

This retrospective cohort study included 523 veterans who survived an initial stroke hospitalization in a VHA medical center during fiscal year 2003. The survivors were followed using administrative data documenting inpatient stroke treatment, patient demographics, disease comorbidities, and VHA hospital admissions. Multivariate Poisson regression was used to examine the relationship between patients with and without SMI diagnosis preceding the stroke and their experience with non-psychiatric medical hospitalizations after the stroke.

RESULTS

The study included 100 patients with SMI and 423 without SMI. Unadjusted means for pre-stroke non-psychiatric hospitalizations were higher (p = 0.0004) among SMI patients (1.47 ± 0.51) compared to those without SMI (1.00 ± 1.33), a difference which persisted through the first year post-stroke (SMI: 2.33 ± 2.46; No SMI: 1.74 ± 1.86; p = 0.0004). Number of non-psychiatric hospitalizations were not significantly different between the two groups after adjustment for patient sociodemographic, comorbidity, length of stay and inpatient stroke treatment characteristics. Antithrombotic medications significantly lowered risk (OR = 0.61; 95% CI: 0.49-0.73) for stroke-related readmission within 30 days of discharge.

CONCLUSIONS

No significant differences in medical hospitalizations were present after adjusting for comorbid and sociodemographic characteristics between SMI and non-SMI stroke patients in the five-year follow-up. However, unadjusted results continue to draw attention to disparities, with SMI patients experiencing more non-psychiatric hospitalizations both prior to and up to one year after their initial stroke. Additionally, stroke survivors discharged on antithrombotic medications were at lower risk of re-admission within 30 days suggesting the VHA should continue to focus on effective stroke management irrespective of SMI.

Effect of charted mental illness on reperfusion therapy in hospitalized patients with an acute myocardial infarction in Florida

Patients with mental illness carry risk factors that predispose them to excess cardiovascular mortality from an acute myocardial infarction (AMI) compared to the general population. The aim of this study was to determine if patients with AMI and charted mental illness (CMI) received less reperfusion therapy following an AMI, compared to AMI patients without CMI in a recent sample population from Florida.A secondary analysis of data was conducted using the Florida Agency for Health Care Administration (FL-AHCA) hospital discharge registry. Adults hospitalized with an AMI from 01/01/2010 to 12/31/2015 were included for the analysis. The dependent variable was administration of reperfusion therapy (thrombolytic, percutaneous coronary intervention [PCI], and coronary artery bypass graft [CABG]), and the independent variable was the presence of CMI (depression, schizophrenia, and bipolar disorder). Multivariate logistic regression models were used to test the association controlling for age, gender, ethnicity, race, health insurance, and comorbidities.The database included 61,614 adults (31.3% women) hospitalized with AMI in Florida. The CMI population comprised of 1036 patients (1.7%) who were on average 5 years younger than non-CMI (60.2 ±12.8 versus 65.2 ±14.1; P < .001). Compared with patients without CMI, patients with CMI had higher proportions of women, governmental health insurance holders, and those with more comorbidities. The adjusted odds ratio indicated that patients with CMI were 30% less likely to receive reperfusion therapy compared with those without CMI (OR = 0.7; 95% CI = 0.6-0.8). Within the AMI population including those with and without CMI, women were 23% less likely to receive therapy than men; blacks were 26% less likely to receive reperfusion therapy than whites; and those holding government health insurances were between 20% and 40% less likely to receive reperfusion therapy than those with private health insurance.Patients with AMI and CMI were statistically significantly less likely to receive reperfusion therapy compared with patients without CMI. These findings highlight the need to implement AMI management care aimed to reduce disparities among medically vulnerable patients (those with CMI, women, blacks, and those with governmental health insurance).

Health care disparities among persons with comorbid schizophrenia and cardiovascular disease: a case-control epidemiological study

AIMS

Studies showed health care disparities among persons with comorbid schizophrenia and cardiovascular disease (CVD), including in countries with universal health care. However, the potential positive effect of specific mental health legislation has not been reported. This study aimed to investigate the health care of persons with comorbid schizophrenia and CVD in a country with both a national health insurance and a comprehensive rehabilitation law for persons with mental disabilities.

METHOD

This study builds on a large case-control epidemiological sample (N = 52 189) of service users. Within the sample we identified a sub-group of persons with CVD diagnoses (n = 8208) and compared service users with and without schizophrenia on drug utilisation, laboratory tests, visits to specialists and surgical interventions.

RESULTS

Service users with schizophrenia were less likely to meet similar indexes of care as their counterparts: 91% cholesterol tests (p < 0.001), 60% stress tests (p < 0.001), 93% visits to specialists (p = 0.001), 93% drug utilisation (p < 0.001) and 55% CVD surgical interventions (odds ratio 0.55, 95% confidence intervals 0.49-0.61).

CONCLUSIONS

In Israel, a country with a national health insurance and a rehabilitation law specific for persons with mental disabilities, service users with schizophrenia still fail to receive equitable levels of health care for CVD. However, the disparities appear to be smaller than in other countries with universal health insurance.

Comparison of Trends in Incidence, Revascularization, and In-Hospital Mortality in ST-Elevation Myocardial Infarction in Patients With Versus Without Severe Mental Illness

Patients with severe mental illness (SMI), including schizophrenia and bipolar disorder, are at elevated risk of ST-elevation myocardial infarction (STEMI) but have previously been reported as less likely to receive revascularization. To study the persistence of these findings over time, we examined trends in STEMI incidence, revascularization, and in-hospital mortality for patients with and without SMI in the National Inpatient Sample from 2003 to 2012. We further used multivariate logistic regression analysis to assess the odds of revascularization and in-hospital mortality. SMI was present in 29,503 of 3,058,697 (1%) of the STEMI population. Patients with SMI were younger (median age 58 vs 67 years), more likely to be women (44% vs 38%), and more likely to have several co-morbidities, including diabetes, chronic pulmonary disease, substance abuse, and obesity (p <0.001 for all). Over time, STEMI incidence significantly decreased in non-SMI (p for trend <0.001) but not in SMI (p for trend 0.14). Revascularization increased in all subgroups (p for trend <0.001) but remained less common in SMI. In-hospital mortality decreased in non-SMI (p for trend = 0.004) but not in SMI (p for trend 0.10). After adjustment, patients with SMI were less likely to undergo revascularization (odds ratio 0.59, 95% CI 0.52 to 0.61, p <0.001), but SMI was not associated with increased in-hospital mortality (odds ratio 0.97, 95% CI 0.93 to 1.01, p = 0.16). In conclusion, in contrast to the overall population, the incidence of STEMI is not decreasing in patients with SMI. Despite changes in the care of STEMI, patients with SMI remain less likely to receive revascularization therapies.

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.

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.

Inpatient and outpatient costs in patients with coronary artery disease and mental disorders: a systematic review

Background

To systematically review in- and outpatient costs in patients with coronary artery disease (CAD) and comorbid mental disorders.

Methods

A comprehensive database search was conducted for studies investigating persons with CAD and comorbid mental disorders (Medline, EMBASE, PsycINFO, Psyndex, EconLit, IBSS). All studies were included which allowed a comparison of in- and outpatient health care costs (assessed either monetarily or in terms of health care utilization) of CAD patients with comorbid mental disorders (mood, anxiety, alcohol, eating, somatoform and personality disorders) and those without. Random effects meta-analyses were conducted and results reported using forest plots.

Results

The literature search resulted in 7,275 potentially relevant studies, of which 52 met inclusion criteria. Hospital readmission rates were increased in CAD patients with any mental disorder (pooled standardized mean difference (SMD) = 0.34 [0.17;0.51]). Results for depression, anxiety and posttraumatic stress disorder pointed in the same direction with heterogeneous SMDs on a primary study level ranging from −0.44 to 1.26. Length of hospital stay was not increased in anxiety and any mental disorder, while studies on depression reported heterogeneous SMDs ranging from −0.08 to 0.82. Most studies reported increased overall and outpatient costs for patients with comorbid mental disorders. Results for invasive procedures were non-significant respectively inconclusive.

Conclusions

Comorbid mental disorders in CAD patients are associated with an increased healthcare utilization in terms of higher hospital readmission rates and increased overall and outpatient health care costs. From a health care point of view, it is requisite to improve the diagnosis and treatment of comorbid mental disorders in patients with CAD to minimize incremental costs.

Mental illness and intensification of diabetes medications: an observational cohort study

BACKGROUND

Mental health condition (MHC) comorbidity is associated with lower intensity care in multiple clinical scenarios. However, little is known about the effect of MHC upon clinicians' decisions about intensifying antiglycemic medications in diabetic patients with poor glycemic control. We examined whether delay in intensification of antiglycemic medications in response to an elevated Hemoglobin A1c (HbA1c) value is longer for patients with MHC than for those without MHC, and whether any such effect varies by specific MHC type.

METHODS

In this observational study of diabetic Veterans Health Administration (VA) patients on oral antiglycemics with poor glycemic control (HbA1c ≥8) (N =52,526) identified from national VA databases, we applied Cox regression analysis to examine time to intensification of antiglycemics after an elevated HbA1c value in 2003-2004, by MHC status.

RESULTS

Those with MHC were no less likely to receive intensification: adjusted Hazard Ratio [95% CI] 0.99 [0.96-1.03], 1.13 [1.04-1.23], and 1.12 [1.07-1.18] at 0-14, 15-30 and 31-180 days, respectively. However, patients with substance use disorders were less likely than those without substance use disorders to receive intensification in the first two weeks following a high HbA1c, adjusted Hazard Ratio 0.89 [0.81-0.97], controlling for sex, age, medical comorbidity, other specific MHCs, and index HbA1c value.

CONCLUSIONS

For most MHCs, diabetic patients with MHC in the VA health care system do not appear to receive less aggressive antiglycemic management. However, the subgroup with substance use disorders does appear to have excess likelihood of non-intensification; interventions targeting this high risk subgroup merit attention.

Psychiatric disorders and pain treatment in community nursing homes

OBJECTIVE

Effective pain assessment and pain treatment are key goals in community nursing homes, but residents' psychiatric disorders may interfere with attaining these goals. This study addressed whether (1) pain assessment and treatment obtained by nursing home residents with psychiatric disorders differs from that obtained by residents without psychiatric disorders; (2) this difference is found consistently across the four types of psychiatric disorder most prevalent in nursing homes (dementia, depression, serious mental illness, and substance use disorder); and (3) male gender, non-white, and longer length of stay add to psychiatric disorders to elevate risk of potentially adverse pain ratings and pain treatments.

METHODS

In this cross-sectional study, we examined relationships among National Nursing Home Survey 2004 residents' demographic, diagnostic, pain, and pain treatment characteristics.

RESULTS

Compared with residents without psychiatric disorders, those with psychiatric disorders were less likely to be rated as having pain in the last 7 days and had lower and more "missing" or "don't know" pain severity ratings. They also were less likely to obtain opioids and more likely to be given only nonopioid pain medications, even after statistically adjusting for demographic factors, physical functioning, and pain severity. These effects generally held across all four types of psychiatric disorders most prevalent in nursing homes and were compounded by male, non-white, and longer-stay status.

CONCLUSION

Psychiatric disorders besides dementia may impact pain assessment and treatment in nursing homes. Nursing home residents with psychiatric disorders, especially male, non-white, and longer-stay residents, should be targeted for improved pain care.

Cardiovascular drug use and mortality in patients with schizophrenia or bipolar disorder: a Danish population-based study

BACKGROUND

Cardiovascular (CV) co-morbidity is one of the major modifiable risk factors driving the excess mortality in individuals with schizophrenia or bipolar disorder. Population-based studies in this area are sparse.

METHOD

We used Danish population registers to calculate incidence rate ratios (IRRs) for CV drug use, and mortality rate ratios comparing subjects with schizophrenia or bipolar disorder with subjects with no prior psychiatric hospitalization.

RESULTS

IRRs for CV prescriptions were significantly decreased in patients with schizophrenia or bipolar disorder compared with the general population. Among persons without previous myocardial infarction (MI) or cerebrovascular disease, persons with schizophrenia or bipolar disorder had an up to 6- and 15-fold increased mortality from all causes or unnatural causes, respectively, compared with the general population, being most pronounced among those without CV treatment (16-fold increase). Among those with previous MI or cerebrovascular disease, excess all-cause and unnatural death was lower (up to 3-fold and 7-fold increased, respectively), but was similar in CV-treated and -untreated persons.

CONCLUSIONS

The present study shows an apparent under-prescription of most CV drugs among patients with schizophrenia or bipolar disorder compared with the general population in Denmark. The excess of mortality by unnatural deaths in the untreated group suggests that the association between CV treatment and mortality may be confounded by severity of illness. However, our results also suggest that treatment of CV risk factors is neglected in these patients.

Disparities in treatment of people with mental disorder in non-psychiatric hospitals: a review of the literature

People with mental disorder experience a heavy burden of physical ill-health. This, alongside structural health-system changes, means more people with mental disorder are being cared for in non-psychiatric hospitals. This article reports on 32 studies that have investigated the care and outcomes of people with comorbid mental and physical health problems in non-psychiatric hospitals. Prevalence of mental disorder ranged between 4%-46%, and rates of psychiatric referral was 2%-10%. The receipt of invasive cardiac procedures was markedly reduced for those with mental disorder. Likelihood of experiencing an adverse event, post-operative complication or increased length of stay was also elevated for those with mental disorder.

Excess early mortality in schizophrenia

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.

Differences in the prescribing of medication for physical disorders in individuals with v. without mental illness: meta-analysis

BACKGROUND

There is some concern that patients with mental illness may be in receipt of inferior medical care, including prescribed medication for medical conditions.

AIMS

We aimed to quantify possible differences in the prescription of medication for medical conditions in those with v. without mental illness.

METHOD

Systematic review and random effects meta-analysis with a minimum of three independent studies to warrant pooling by drug class.

RESULTS

We found 61 comparative analyses (from 23 publications) relating to the prescription of 12 classes of medication for cardiovascular health, diabetes, cancer, arthritis, osteoporosis and HIV in a total sample of 1 931 509 people. In those with severe mental illness the adjusted odds ratio (OR) for an equitable prescription was 0.74 (95% CI 0.63-0.86), with lower than expected prescriptions for angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers (ACE/ARBs), beta-blockers and statins. People with affective disorder had an odds ratio of 0.75 (95% CI 0.55-1.02) but this was not significant. Individuals with a history of other (miscellaneous) mental illness had an odds ratio of 0.95 (95% CI 0.92-0.98) of comparable medication with lower receipt of ACE/ARBs but not highly active antiretroviral therapy (HAART) medication. Results were significant in both adjusted and unadjusted analyses.

CONCLUSIONS

Individuals with severe mental illness (including schizophrenia) appear to be prescribed significantly lower quantities of several common medications for medical disorders, largely for cardiovascular indications, although further work is required to clarify to what extent this is because of prescriber intent.

Mental illness, access to hospitals with invasive cardiac services, and receipt of cardiac procedures by Medicare acute myocardial infarction patients

OBJECTIVE

Older persons with coronary heart disease have reduced access to appropriate medical and surgical services if they are also mentally ill. This study determined whether difference exists in access to hospitals that provide on-site invasive cardiac procedures among a national cohort of Medicare acute myocardial infarction (AMI) patients with and without comorbid mental illness, and its implications for subsequent procedure use.

METHODS

Retrospective analyses of Medicare claims for initial AMI admissions between January and September 2007. Hospital service availability was obtained from annual survey data. Logistic regression estimated the associations of mental illness with admission to hospitals with any invasive cardiac services (diagnostic catheterization, coronary angioplasty, or bypass surgery) and post-admission care patterns and outcomes.

RESULTS

Eighty-two percent of mentally ill AMI patients (n = 28,888) versus 87 percent of other AMI patients (n = 73,895) were initially admitted to hospitals with invasive cardiac facilities [adjusted odds ratio (OR) = 0.81, p < .001]. Admission to such hospitals was associated with overall higher rate of procedure use within 90 days of admission and improved 30-days readmission and mortality rates. However, irrespective of on-site service availability of the admitting hospital, mentally ill patients were one half as likely to receive invasive procedures (adjusted OR approximately 0.5, p < .001).

CONCLUSIONS

Among Medicare patients with AMI, those with comorbid mental illness were less likely to be admitted to hospitals with on-site invasive cardiac services. Mental illness was associated with reduced cardiac procedure use within each type of admitting hospitals (with on-site invasive cardiac services or not).

Post-myocardial-infarction quality of care among disabled Medicaid beneficiaries with and without serious mental illness

OBJECTIVE

The objective was to examine the association between serious mental illness and quality of care for myocardial infarction among disabled Maryland Medicaid beneficiaries.

METHODS

We conducted a retrospective cohort study of disabled Maryland Medicaid beneficiaries with myocardial infarction from 1994 to 2004. Cardiac procedures and guideline-based medication use were compared for persons with and without serious mental illness.

RESULTS

Of the 633 cohort members with myocardial infarction, 137 had serious mental illness. Serious mental illness was not associated with differences in receipt of cardiac procedures or guideline-based medications. Overall use of guideline-based medications was low; 30 days after the index hospitalization for myocardial infarction, 19%, 35% and 11% of cohort members with serious mental illness and 22%, 37% and 13% of cohort members without serious mental illness had any use of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, beta-blockers and statins, respectively. Study participants with and without serious mental illness had similar rates of mortality. Overall, use of beta-blockers [hazard ratio 0.93, 95% confidence interval (CI) 0.90-0.97] and statins (hazard ratio 0.93, 95% CI 0.89-0.98) was associated with reduced risk of mortality.

CONCLUSIONS

Quality improvement programs should consider how to increase adherence to medications of known benefit among disabled Medicaid beneficiaries with and without serious mental illness.

Service integration for the dually diagnosed

The needs of dually diagnosed clients in mental health services have been and remain a focus for service development and improvement in Australia. The Council of Australian Governments committed to a five-year National Action Plan on Mental Health with a $1.8 billion injection into mental health services. In Australia there have been great advances in the service initiatives and service deliverables to those clients who experience a dual diagnosis. These advances include that dual diagnosis is systematically identified and responded to in a timely, evidence-based manner as a core business in mental health and alcohol and other drug services. These advances are brought to life by specialist mental health and alcohol and other drug services that establish effective partnerships and agreed mechanisms to support integrated care and collaborative practice. Here, four case studies are offered as a means of illustrating the ways in which projects undertaken in local community health services have approached dual diagnosis treatment for clients. These case studies reflect how cooperation and cross-referral between services, as well as effective management of dual diagnosis clients by suitably qualified staff can produce benefits to clients who use the service.

How does a history of psychiatric hospital care influence access to coronary care: a cohort study

OBJECTIVES

Equity in physical health of patients with severe mental disorders is a major public health concern. The aim of this cohort study was to examine equity in access to coronary care among persons with a history of severe mental disorder in 1998-2009.

DESIGN

Nationwide register linkage cohort study.

SETTING

Hospital care in the Finnish healthcare system.

POPULATION

The study population consisted of all residents in Finland aged 40 years or older. All hospital discharges in 1998-2009 with a diagnosis of coronary heart disease or severe mental disorder were obtained from the Care Register.

PRIMARY OUTCOME MEASURES

Data on deaths, hospitalisations and coronary revascularisations were linked to the data set using unique personal identifiers.

RESULTS

Patients with severe mental disorders had increased likelihood of hospital care due to coronary heart disease (RR between 1.22, 95% CI 1.18 to 1.25 and 1.93, 1.84 to 2.03 in different age groups) and in 40-49-year-olds also increased likelihood of revascularisation (1.26, 1.16 to 1.38) compared with persons without mental disorders. Access to revascularisation was poorer among older persons with severe mental disorders in relation to need suggested by increased coronary mortality. In spite of excess coronary mortality (ranging from 0.95, 0.89 to 1.01 to 3.16, 2.82 to 3.54), worst off were people with a history of psychosis, who did not have increased use of hospital care and had lower likelihood of receiving revascularisations (ranging from 0.44, 0.37 to 0.51 to 0.74, 0.59 to 0.93) compared with persons without mental disorders.

CONCLUSIONS

Selective mechanisms seem to be at work in access to care and revascularisations among people with severe mental disorders. Healthcare professionals need to be aware of the need for targeted measures to address challenges in provision of somatic care among people with severe mental health problems, especially among people with psychoses and old people.

Tradeoffs between accuracy measures for electronic health care data algorithms

OBJECTIVE

We review the uses of electronic health care data algorithms, measures of their accuracy, and reasons for prioritizing one measure of accuracy over another.

STUDY DESIGN AND SETTING

We use real studies to illustrate the variety of uses of automated health care data in epidemiologic and health services research. Hypothetical examples show the impact of different types of misclassification when algorithms are used to ascertain exposure and outcome.

RESULTS

High algorithm sensitivity is important for reducing the costs and burdens associated with the use of a more accurate measurement tool, for enhancing study inclusiveness, and for ascertaining common exposures. High specificity is important for classifying outcomes. High positive predictive value is important for identifying a cohort of persons with a condition of interest but that need not be representative of or include everyone with that condition. Finally, a high negative predictive value is important for reducing the likelihood that study subjects have an exclusionary condition.

CONCLUSION

Epidemiologists must often prioritize one measure of accuracy over another when generating an algorithm for use in their study. We recommend researchers publish all tested algorithms-including those without acceptable accuracy levels-to help future studies refine and apply algorithms that are well suited to their objectives.

Quality of care for cardiovascular disease and diabetes amongst individuals with serious mental illness and those using antipsychotic medications

Individuals living with serious mental illness (SMI) experience excess mortality due to natural causes. Cardiovascular disease (CVD) and diabetes are twice as prevalent in SMI populations as in the general population, and this may be partly related to unhealthy lifestyle behaviors and the use of antipsychotic medications. This review examined comparative studies of quality of care in SMI and non-SMI populations, and studies investigating cardio-metabolic screening in patients prescribed antipsychotics. We identified that individuals with SMI are around 30% less likely than those without SMI to receive hospital care for CVD and diabetes complications, to receive blood glucose, lipid, and other diabetes tests, to undergo invasive procedures, and to be prescribed medications known to be effective in the treatment of CVD and diabetes. In addition, less than 30% of individuals with SMI may receive examinations for weight, blood glucose, and lipids, before or during treatment with antipsychotics. Evidence from studies within the U.S.' Veteran Affairs health care system indicates that the integration of physical and mental health services may be beneficial in reducing disparities in health care for individuals with SMI. Clear policies, which identify practitioner responsibilities for cardio-metabolic screening in patients receiving antipsychotic therapy must be disseminated.

Revascularisation and mortality rates following acute coronary syndromes in people with severe mental illness: comparative meta-analysis

BACKGROUND

High levels of comorbid physical illness and excess mortality rates have been previously documented in people with severe mental illness, but outcomes following myocardial infarction and other acute coronary syndromes are less clear.

AIMS

To examine inequalities in the provision of invasive coronary procedures (revascularisation, angiography, angioplasty and bypass grafting) and subsequent mortality in people with mental illness and in those with schizophrenia, compared with those without mental ill health.

METHOD

Systematic search and random effects meta-analysis were used according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies of mental health and cardiovascular procedures following cardiac events were eligible but we required a minimum of three independent studies to warrant pooling by procedure type. We searched Medline/PubMed and EMBASE abstract databases and ScienceDirect, Ingenta Select, SpringerLink and Online Wiley Library full text databases.

RESULTS

We identified 22 analyses of possible inequalities in coronary procedures in those with defined mental disorder, of which 10 also reported results in schizophrenia or related psychosis. All studies following acute coronary syndrome originated in the USA. The total sample size was 825 754 individuals. Those with mental disorders received 0.86 (relative risk, RR: 95% CI 0.80-0.92, P<0.0001) of comparable procedures with significantly lower receipt of coronary artery bypass graft (CABG; RR = 0.85, 95% CI 0.72-1.00), cardiac catheterisation (RR = 0.85, 95% CI 0.76-0.95) and percutaneous transluminal coronary angioplasty or percutaneous coronary intervention (PTCA/PCI; RR = 0.87, 95% CI 0.72-1.05). People with a diagnosis of schizophrenia received only 0.53 (95% CI 0.44-0.64, P<0.0001) of the usual procedure rate with significantly lower receipt of CABG (RR = 0.69, 95% CI 0.55-0.85) and PTCA/PCI (RR = 0.50, 95% CI 0.34-0.75). We identified 6 related studies examining mortality following cardiac events: for those with mental illness there was a 1.11 relative risk of mortality up to 1 year (95% CI 1.00-1.24, P = 0.05) but there was insufficient evidence to examine mortality rates in schizophrenia alone.

CONCLUSIONS

Following cardiac events, individuals with mental illness experience a 14% lower rate of invasive coronary interventions (47% in the case of schizophrenia) and they have an 11% increased mortality rate. Further work is required to explore whether these factors are causally linked and whether improvements in medical care might improve survival in those with mental ill health.

Cardiovascular risk assessment and management in mental health clients: whose role is it anyway?

People with serious mental illness have higher rates of morbidity and mortality from cardiovascular disease. This study describes health practitioners' views on their role and confidence assessing and managing cardiovascular risk. The key findings were of a widespread acknowledgement of the need to undertake systematic risk assessment and offer structured approaches to risk factor management. Barriers of client engagement, lack of good systems and poor information sharing between primary and secondary care providers were identified. Solutions discussed included a collaborative care model or the integration of physical health services, perhaps a general practitioner-led clinic, within the secondary care setting. Whilst there is a need to identify an optimal care model there is an even greater need to take some rather than no action.

Do deficits in cardiac care influence high mortality rates in schizophrenia? A systematic review and pooled analysis

We have previously documented inequalities in the quality of medical care provided to those with mental ill health but the implications for mortality are unclear. We aimed to test whether disparities in medical treatment of cardiovascular conditions, specifically receipt of medical procedures and receipt of prescribed medication, are linked with elevated rates of mortality in people with schizophrenia and severe mental illness. We undertook a systematic review of studies that examined medical procedures and a pooled analysis of prescribed medication in those with and without comorbid mental illness, focusing on those which recruited individuals with schizophrenia and measured mortality as an outcome. From 17 studies of treatment adequacy in cardiovascular conditions, eight examined cardiac procedures and nine examined adequacy of prescribed cardiac medication. Six of eight studies examining the adequacy of cardiac procedures found lower than average provision of medical care and two studies found no difference. Meta-analytic pooling of nine medication studies showed lower than average rates of prescribing evident for the following individual classes of medication; angiotensin converting enzyme inhibitors (n = 6, aOR = 0.779, 95% CI = 0.638-0.950, p = 0.0137), beta-blockers (n = 9, aOR = 0.844, 95% CI = 0.690-1.03, p = 0.1036) and statins (n = 5, aOR = 0.604, 95% CI = 0.408-0.89, p = 0.0117). No inequality was evident for aspirin (n = 7, aOR = 0.986, 95% CI = 0.7955-1.02, p = 0.382). Interestingly higher than expected prescribing was found for older non-statin cholesterol-lowering agents (n = 4, aOR = 1.55, 95% CI = 1.04-2.32, p = 0.0312). A search for outcomes in this sample revealed ten studies linking poor quality of care and possible effects on mortality in specialist settings. In half of the studies there was significantly higher mortality in those with mental ill health compared with controls but there was inadequate data to confirm a causative link. Nevertheless, indirect evidence supports the observation that deficits in quality of care are contributing to higher than expected mortality in those with severe mental illness (SMI) and schizophrenia. The quality of medical treatment provided to those with cardiac conditions and comorbid schizophrenia is often suboptimal and may be linked with avoidable excess mortality. Every effort should be made to deliver high-quality medical care to people with severe mental illness.

Preexisting comorbid psychiatric conditions and mortality in nonsurgical intensive care patients

PURPOSE

To examine the effects of preexisting comorbid psychiatric conditions on mortality in a large cohort of patients admitted to a nonsurgical intensive care unit.

METHODS

This retrospective cohort study involved 66,672 consecutive eligible nonsurgical patients admitted to intensive care units in 129 Veterans Health Administration hospitals during 2005 and 2006. Preexisting comorbid psychiatric conditions were identified by using diagnoses from outpatient encounters in the prior year for depression, anxiety, psychosis, bipolar disorders, and posttraumatic stress disorder. Generalized estimating equations were used to adjust the risks of in hospital and 30-day mortality for demographics, comorbid medical conditions, markers of severity, and abnormal findings on laboratory tests at admission.

RESULTS

Comorbid psychiatric conditions were identified in 28% (n = 18 698) of patients. Patients with preexisting comorbid psychiatric conditions had lower (P < .001) unadjusted in hospital mortality (7.3% vs 8.7%) and 30-day mortality (10.0% vs 12.8%) than did patients without such conditions. After demographics, comorbid medical conditions, and severity were adjusted for, risk of in-hospital mortality among patients with comorbid psychiatric conditions was somewhat higher (odds ratio, 1.07, 95% confidence interval, 1.01-1.14; P = .02), although differences in 30-day mortality (odds ratio, 1.01, 95% confidence interval, 0.94-1.08; P = .70) were no longer significant.

CONCLUSION

Preexisting comorbid psychiatric conditions are common among intensive care patients, but after comorbid medical conditions and severity were adjusted for, preexisting comorbid psychiatric conditions were not associated with a higher risk of 30-day mortality in a large national cohort of veterans.

Treatment of ischaemic heart disease and stroke in individuals with psychosis under universal healthcare

BACKGROUND

Most data on the quality of vascular care for individuals with psychiatric conditions come from countries without universal healthcare.

AIMS

To investigate the treatment of people with psychosis admitted for ischaemic heart disease or stroke under universal healthcare.

METHOD

A population-based study of administrative data comparing Canadians with and without a history of schizophrenia or related psychosis (n = 65,039).

RESULTS

Of 49 248 admissions for ischaemic heart disease, 1285 had a history of psychosis. Despite a higher 1-year mortality, they were less likely to receive guideline-consistent treatment: e.g. coronary artery bypass grafting (adjusted odds ratio (OR) = 0.35, 95% CI 0.25-0.48), beta-blockers (adjusted OR = 0.82, 95% CI 0.71-0.95) and statins (adjusted OR = 0.51, 95% CI 0.41-0.63). Of 15 791 admissions for stroke, 594 had a history of psychosis. Despite higher 1-year mortality rates, they were less likely to receive cerebrovascular arteriography or warfarin.

CONCLUSIONS

People with a history of psychosis do not receive equitable levels of vascular care under universal healthcare.

Quality of medical care for people with and without comorbid mental illness and substance misuse: systematic review of comparative studies

BACKGROUND

There has been long-standing concern about the quality of medical care offered to people with mental illness.

AIMS

To investigate whether the quality of medical care received by people with mental health conditions, including substance misuse, differs from the care received by people who have no comparable mental disorder.

METHOD

A systematic review of studies that examined the quality of medical care in those with and without mental illness was conducted using robust critical appraisal techniques.

RESULTS

Of 31 valid studies, 27 examined receipt of medical care in those with and without mental illness and 10 examined medical care in those with and without substance use disorder (or dual diagnosis). Nineteen of 27 and 10 of 10, respectively, suggested inferior quality of care in at least one domain. Twelve studies found no appreciable differences in care or failed to detect a difference in at least one key area. Several studies showed an increase in healthcare utilisation but without any increase in quality. Three studies found superior care for individuals with mental illness in specific subdomains. There was inadequate information concerning patient satisfaction and structural differences in healthcare delivery. There was also inadequate separation of delivery of care from uptake in care on which to base causal explanations.

CONCLUSIONS

Despite similar or more frequent medical contacts, there are often disparities in the physical healthcare delivered to those with psychiatric illness although the magnitude of this effect varies considerably.

Psychiatric comorbidity and mortality after acute myocardial infarction

BACKGROUND

Prior studies of the impact of psychiatric comorbidity on outcomes after acute myocardial infarction (AMI) have frequently relied on inpatient secondary diagnosis codes. This study compared associations between psychiatric comorbidity and AMI outcomes that were derived using secondary diagnosis codes and codes captured from prior outpatient encounters.

METHODS AND RESULTS

Retrospective cohort study analyzing 21 745 patients admitted in 2004 to 2006 to Veterans Health Administration hospitals with AMI using administrative data. Psychiatric comorbidity was identified using (1) secondary inpatient diagnosis codes from the index hospitalization and (2) diagnoses from prior outpatient encounters. Outcomes included 30- and 365-day mortality and the receipt of coronary revascularization within 30 days of admission. Generalized estimating equations and Cox proportional hazards were used to adjust mortality and receipt of revascularization for demographic and clinical variables. Psychiatric disorders were identified in 2285 (10%) patients from inpatient secondary diagnosis codes and 5225 (24%) patients from prior outpatient codes. Patients with psychiatric comorbidity had higher adjusted 30- and 365-day mortality, based on outpatient codes (odds ratios, 1.19 [95% CI, 1.09 to 1.30] and 1.12 [95% CI, 1.03 to 1.22], respectively), but similar mortality based on inpatient codes (odds ratios, 0.89 [95% CI, 0.69 to 1.01] and 0.93 [95% CI, 0.82 to 1.06], respectively). In contrast, patients with psychiatric comorbidity had lower receipt of coronary revascularization based on outpatient codes (hazard ratio, 0.92; [95% CI, 0.85 to 0.99], but similar receipt based on inpatient codes (hazard ratio, 1.00 [95% CI, 0.91 to 1.10]).

CONCLUSIONS

Inpatient secondary diagnosis codes identified fewer patients with psychiatric comorbidity than prior outpatient codes. Moreover, associations with AMI outcomes differed for the 2 approaches. These findings raise potential concerns about the validity and reliability of psychiatric inpatient secondary diagnosis in estimating the impact of psychiatric comorbidities on AMI outcomes and in developing risk-adjustment models.

Excess mortality in persons with severe mental disorder in Sweden: a cohort study of 12 103 individuals with and without contact with psychiatric services

Background

Investigating mortality in those with mental disorder is one way of measuring effects of mental health care reorganisation. This study's aim was to investigate whether the excess mortality in those with severe mental disorder remains high in Sweden after the initiation of the Community Mental Health Care Reform. We analysed excess mortality by gender, type of mental health service and psychiatric diagnosis in a large community-based cohort with long-term mental disorder.

Methods

A survey was conducted in Stockholm County, Sweden in 1997 to identify adults with long-term disabling mental disorder (mental retardation and dementia excluded). The 12 103 cases were linked to the Hospital Discharge Register and the Cause of Death Register. Standardised mortality ratios (SMRs) for 1998–2000 were calculated for all causes of death, in the entire cohort and in subgroups based on treatment setting and diagnosis.

Results

Mortality was increased in both genders, for natural and external causes and in all diagnostic subgroups. Excess mortality was greater among those with a history of psychiatric inpatient care, especially in those with substance use disorder. For the entire cohort, the number of excess deaths due to natural causes was threefold that due to external causes. SMRs in those in contact with psychiatric services where strikingly similar to those in contact with social services.

Conclusion

Mortality remains high in those with long-term mental disorder in Sweden, regardless of treatment setting. Treatment programs for persons with long-term mental disorder should target physical as well as mental health.

Monitoring the physical health of individuals with serious mental illness

Developing effective models of identifying and managing physical ill health amongst mental health service users has become an increasing concern for psychiatric service providers. This article sets out the general professional and Irish statutory obligations to provide physical health monitoring services for individuals with serious mental illness. Review and summary statements are provided in relation to the currently available guidelines on physical health monitoring.

Variations in the associations between psychiatric comorbidity and hospital mortality according to the method of identifying psychiatric diagnoses

OBJECTIVE

Little is known about associations between psychiatric comorbidity and hospital mortality for acute medical conditions. This study examined if associations varied according to the method of identifying psychiatric comorbidity and agreement between the different methods.

PATIENTS/PARTICIPANTS

The sample included 31,218 consecutive admissions to 168 Veterans Affairs facilities in 2004 with a principle diagnosis of congestive heart failure (CHF) or pneumonia. Psychiatric comorbidity was identified by: (1) secondary diagnosis codes from index admission, (2) prior outpatient diagnosis codes, (3) and prior mental health clinic visits. Generalized estimating equations (GEE) adjusted in-hospital mortality for demographics, comorbidity, and severity of illness, as measured by laboratory data.

MEASUREMENTS AND MAIN RESULTS

Rates of psychiatric comorbidities were 9.0% using inpatient diagnosis codes, 27.4% using outpatient diagnosis codes, and 31.0% using mental health visits for CHF and 14.5%, 33.1%, and 34.1%, respectively, for pneumonia. Agreement was highest for outpatient codes and mental health visits (kappa = 0.51 for pneumonia and 0.50 for CHF). In GEE analyses, the adjusted odds of death for patients with psychiatric comorbidity were lower when such comorbidity was identified by mental health visits for both pneumonia (odds ratio [OR] = 0.85; P = .009) and CHF (OR = 0.70; P < .001) and by inpatient diagnosis for pneumonia (OR = 0.63; P < or = .001) but not for CHF (OR = 0.75; P = .128). The odds of death were similar (P > .2) for psychiatric comorbidity as identified by outpatient codes for pneumonia (OR = 1.04) and CHF (OR = 0.93).

CONCLUSIONS

The method used to identify psychiatric comorbidities in acute medical populations has a strong influence on the rates of identification and the associations between psychiatric illnesses with hospital mortality.

Disparities in appendicitis rupture rate among mentally ill patients

BACKGROUND

Many studies have been carried out that focus on mental patients' access to care for their mental illness, but very few pay attention on these same patients' access to care for their physical diseases. Acute appendicitis is a common surgical emergency. Our population-based study was to test for any possible association between mental illness and perforated appendicitis. We hypothesized that there are significant disparities in access to timely surgical care between appendicitis patients with and without mental illness, and more specifically, between patients with schizophrenia and those with another major mental illness.

METHODS

Using the National Health Insurance (NHI) hospital-discharge data, we compared the likelihood of perforated appendix among 97,589 adults aged 15 and over who were hospitalized for acute appendicitis in Taiwan between the years 1997 to 2001. Among all the patients admitted for appendicitis, the outcome measure was the odds of appendiceal rupture vs. appendicitis that did not result in a ruptured appendix.

RESULTS

After adjusting for age, gender, ethnicity, socioeconomic status (SES) and hospital characteristics, the presence of schizophrenia was associated with a 2.83 times higher risk of having a ruptured appendix (odds ratio [OR], 2.83; 95% confidence interval [CI], 2.20-3.64). However, the presence of affective psychoses (OR, 1.15; 95% CI: 0.77-1.73) or other mental disorders (OR, 1.58; 95% CI: 0.89-2.81) was not a significant predictor for a ruptured appendix.

CONCLUSION

These findings suggest that given the fact that the NHI program reduces financial barriers to care for mentally ill patients, they are still at a disadvantage for obtaining timely treatment for their physical diseases. Of patients with a major mental illness, schizophrenic patients may be the most vulnerable ones for obtaining timely surgical care.

Inequalities in the primary care of patients with coronary heart disease and serious mental health problems: a cross-sectional study

OBJECTIVE

To determine whether UK patients with coronary heart disease (CHD) who also have schizophrenia or bipolar disorder are less likely to receive primary care in accordance with the agreed national standards of the UK than patients without these mental health problems.

DESIGN

Cross-sectional study.

SETTING

485 UK general practices contributing anonymised medical records of over 3.26 million patients to the QRESEARCH database.

PARTICIPANTS

127,932 patients with CHD of whom 701 had a diagnosis of schizophrenia or bipolar disorder.

MAIN OUTCOME MEASURES

The relative risks of receiving statin medication and each of the CHD care indicators defined in the UK General Medical Services contract, for patients with schizophrenia or bipolar disorder compared with patients with neither condition. The results were adjusted for age, sex, deprivation, diabetes, stroke and smoking status, and allowed for clustering by practice.

RESULTS

Patients with schizophrenia were 15% less likely to have a recent prescription for a statin (95% CI 8% to 20%) and 7% less likely to have a recent record of cholesterol level (95% CI 3% to 11%). There were no significant differences in the adjusted analyses between mental health groups on recording smoking status, advising on smoking cessation, recording blood pressure, achieving target blood pressure or cholesterol values, or prescribing aspirin, antiplatelets, anticoagulants or beta blockers.

CONCLUSIONS

Although the majority of CHD care indicators are achieved equally for patients who also have a serious mental health problem, there is a shortfall in identifying and treating raised cholesterol among patients with schizophrenia, despite their higher level of risk factors.

Severe mental illness and mortality of hospitalized ACS patients in the VHA

BACKGROUND

Severe mental illness (SMI) has been associated with more medical co-morbidity and less cardiovascular procedure use for older patients with myocardial infarction. However, it is unknown whether SMI is associated with increased long term mortality risk among patients presenting with acute coronary syndromes (ACS). We tested the hypothesis that SMI is associated with higher one-year mortality following ACS hospitalization.

METHODS

All ACS patients (n = 14,194) presenting to Veterans Health Administration (VHA) hospitals between October 2003 and September 2005 were included. Survival analysis evaluated the association between SMI and one-year all-cause mortality, adjusting for demographics, co-morbidities, in-hospital treatment, and discharge medications.

RESULTS

Overall, 18.4 % of ACS patients had SMI. Patients with SMI were more likely female, younger, Caucasian race, have a history of alcohol abuse, liver disease, dementia, hypertension and more likely to be a current smoker; however, prior cardiac history was similar between the 2 groups. There were no significant differences in cardiac procedure use, including coronary angiogram (38.7% vs. 40.3%, p = 0.14) or coronary revascularization (31.0% vs. 32.3%, p = 0.19), and discharge medications between those with and without SMI. One-year mortality was lower for patients with SMI (15.8% vs. 19.1%, p < 0.001). However, in multivariable analysis, there were no significant differences in mortality (HR 0.91; 95% CI 0.81-1.02) between patients with and without SMI.

CONCLUSION

Among ACS patients in the VHA, SMI is prevalent, affecting almost 1 in 5 patients. However, patients with SMI were as likely to undergo coronary revascularization and be prescribed evidence-based medications at hospital discharge, and were not at elevated risk of adverse 1-year outcomes compared to patients without SMI.

Are patients with coexisting mental disorders more likely to receive CABG surgery from low-quality cardiac surgeons? The experience in New York State

BACKGROUND

Presence of a mental disorder has been shown to be associated with reduced access to medical and surgical services. Little is known, however, about the relationship between mental disorders and the quality of medical/surgical care received.

METHODS

We analyzed New York State hospital discharge data between 2001 and 2003 and New York's publicly-released Cardiac Surgery Report of surgeons' risk-adjusted mortality rate, to evaluate whether differences exist between persons with and without mental disorders (specifically, psychiatric and/or substance-use disorders) in receiving care from low-quality and high-quality surgeons performing coronary artery bypass graft (CABG) surgeries.

RESULTS

Controlling for individual demographic, socioeconomic, and clinical characteristics, persons with any mental disorder (n = 3211) were more likely than others (n = 36,628) to be treated by low-quality cardiac surgeons (odds ratio [OR] = 1.28, P = 0.023), whose reported risk-adjusted mortality rates were significantly higher than the state average CABG mortality rate. Compared with patients without mental disorders, patients with psychiatric disorders (n = 2651) showed an increased likelihood of being treated by these low-quality surgeons (OR = 1.36, P = 0.008). In addition, patients with both substance-use and psychiatric disorders (n = 113), but not substance-use alone (n = 447), were more likely to receive care from surgeons in the high-mortality quintile group (OR = 1.76, P = 0.024). There was no significant association between each type of mental disorders and the likelihood of being treated by a low-mortality, high-quality cardiac surgeon.

CONCLUSIONS

New York State patients with mental disorders, especially psychiatric disorders, are more likely to receive CABG surgery from low-quality cardiac surgeons. No evidence suggests that these patients are disadvantaged in access to high-quality cardiac surgeons.

The Implementation of Guidelines and Prognosis among Patients with Acute Coronary Syndromes Is Influenced by Physicians’ Perception of Antecedent Physical and Cognitive Status

BACKGROUND/AIMS

Physicians' perception of antecedent physical/cognitive status may account for the suboptimal implementation of acute coronary syndrome (ACS) guidelines.

METHODS

In an ACS survey of all cardiac wards, physicians' perception of antecedent physical/cognitive status was prospectively recorded and categorized as either normal, mildly impaired or significantly impaired. We examined the impact of antecedent status on the use of evidence-based medications and procedures and on mortality.

RESULTS

Of the 2,021 patients, 1,025 (51%) had ST elevation. Impaired antecedent physical/cognitive status was diagnosed in 417 patients (20.6%), more commonly among non-ST-elevation patients (26.2 vs. 15.2%). Patients with impaired physical/cognitive status, with or without ST elevation, had significantly worse baseline demographic and clinical characteristics. They less often received aspirin, clopidogrel, platelet glycoprotein IIb/IIIa receptor antagonists, statins and beta-adrenergic blockers, and significantly less often underwent in-hospital catheterization and revascularization. Reperfusion treatment was given significantly less frequently to ST elevation patients with impaired status (63.0% for normal vs. 50.8% and 33.3% for mildly and significantly impaired status, respectively; p = 0.001). After adjustment for differences in baseline characteristics, impaired antecedent status remained independently associated with lower use of these therapies and higher mortality rates.

CONCLUSIONS

ACS guideline implementation is significantly influenced by physicians' perception of antecedent physical/cognitive status, and thus is a crucial parameter for understanding ACS management and outcomes.

Doing my best: poverty and self-care among individuals with schizophrenia and diabetes mellitus

Diabetes mellitus (DM) is more common among individuals with schizophrenia/schizoaffective disorders than among the general population. Eleven mental health consumers diagnosed with comorbid schizophrenia/schizoaffective disorder and DM participated in a grounded theory study that examined their approaches to diabetic self-care. The resulting model, Evolving Self-Care, describes the process by which respondents developed health beliefs about the self-care of dual illnesses. One subcategory of the model, Doing My Best, was further analyzed to examine the social context of respondents' diabetic self-care. Limited financial resources and material deprivation interfered with access to the resources necessary for adequate diabetic self-care. Mental health providers are encouraged to provide treatment and patient education that are consistent with the real world living situations of individuals with schizophrenia. Policymakers at the federal and state levels need to address the impact of financing of mental health services on the overall health of vulnerable individuals with serious mental illnesses.

Extent and management of cardiovascular risk factors in patients with type 2 diabetes and serious mental illness

Cardiovascular disease is the leading cause of death in Type 2 diabetes, which commonly occurs in patients with serious mental illnesses (SMIs). We determined the extent to which patients with diabetes and SMI, relative to diabetes patients without SMI, met American Diabetes Association goals for cholesterol and blood pressure, met criteria for the metabolic syndrome, and were prescribed medications known to reduce cardiovascular events. We found that less than half of diabetes patients, both with and without SMI, met recommended goals for cholesterol levels; even fewer had adequate blood pressure control. In addition, a substantial proportion of all diabetes patients met metabolic syndrome criteria. However, diabetes patients with SMI were less likely to be prescribed cholesterol-lowering statin medications, angiotensin-converting enzyme inhibitors, and angiotensin receptor blocking agents than diabetes patients without SMI. Patients with both diabetes and SMI are treated less aggressively for high cardiovascular risk than diabetes patients without mental disorders.
