Comparative mortality risks in two independent bipolar cohorts.

OBJECTIVES: To compare mortality rates in bipolar disorder with common causes of mortality. METHODS: Observational data from the Prechter Longitudinal Study of Bipolar Disorder (PLS-BD) of 1128 participants including 281 controls was analyzed using logistical regression to quantify mortality rates in comparison with common comorbidities and causes of death. Outcome and treatment measures, including ASRM, GAD-7, PHQ-9 and medication use were used to stratify those with bipolar disorder (BD) that are alive or deceased. A larger cohort of 10,735 existing BD patients with 7,826 controls (no psychiatric diagnosis) from the University of Michigan Health (U-M Health) clinics was used as replication, observational secondary data analysis. RESULTS: The mortality rates are significantly different between those with BD and controls in both PLS-BD and U-M Health. Those with BD and are deceased have a higher percentage of elevated depression measures but show no difference in mania or anxiety measures nor medication use patterns. In both cohorts, a diagnosis of BD increases the odds of mortality greater than history of smoking or being older than ≥ 60-years of age. CONCLUSION: BD was found to increase odds of mortality significantly and beyond that of a history of smoking. This finding was replicated in an independent sample.

Comparison of Suicide Risk by Mental Illness: a Retrospective Review of 14-Year Electronic Medical Records.

BACKGROUND: Korea is one of the countries with the highest rate of suicide, while suicidality is known to be closely related to mental illnesses. The study aimed to evaluate the suicide rates in psychiatric patients, to compare it to that of the general population, and to investigate the differences among psychiatric diagnoses and comorbidities. METHODS: Medical records and mortality statistics of psychiatric patients at Seoul National University Hospital from 2003 to 2017 were reviewed. The standardized mortality ratio (SMR) for suicide was calculated to compare the psychiatric patients with the general population. The diagnosis-specific standardized mortality rate and hazard ratio (HR) were adjusted by age, sex, and psychiatric comorbidity (i.e., personality disorder and/or pain disorder). RESULTS: A total of 40,692 survivors or non-suicidal deaths and 597 suicidal death were included. The suicide rate among psychiatric patients was 5.13-fold higher than that of the general population. Psychotic disorder had the highest SMR (13.03; 95% confidence interval [CI], 11.23-15.03), followed by bipolar disorder (10.26; 95% CI, 7.97-13.00) and substance-related disorder (6.78; 95% CI, 4.14-10.47). In survival analysis, psychotic disorder had the highest HR (4.16; 95% CI, 2.86-6.05), which was further increased with younger age, male sex, and comorbidity of personality disorder. CONCLUSION: All psychiatric patients are at a higher risk of suicide compared to the general population, and the risk is highest for those diagnosed with psychotic disorder.

Excess mortality and shortened life expectancy in people with major mental illnesses in Taiwan.

AIMS: Given the concerns of health inequality associated with mental illnesses, we aimed to reveal the extent of which general mortality and life expectancy at birth in people with schizophrenia, bipolar disorder and depressive disorder varied in the 2005 and 2010 nationally representative cohorts in Taiwan. METHODS: Two nationally representative samples of individuals with schizophrenia, bipolar disorder and depressive disorder were identified from Taiwan's national health insurance database in 2005 and 2010, respectively, and followed-up for consecutive 3 years. The database was linked to nationwide mortality registry to identify causes and date of death. Age-, gender- and cause-specific mortality rates were generated, with the average follow-up period of each age- and gender-band applied as 'weighting' for the calculation of expected number of deaths. Age- and gender-standardised mortality ratios (SMRs) were calculated for these 3-year observation periods with Taiwanese general population in 2011/2012 as the standard population. The SMR calculations were then stratified by natural/unnatural causes and major groups of death. Corresponding life expectancies at birth were also calculated by gender, diagnosis of mental disorders and year of cohorts for further elucidation. RESULTS: The general differential in mortality rates for people with schizophrenia and bipolar disorder remained wide, revealing an SMR of 3.65 (95% confidence interval (CI): 3.55-3.76) for cohort 2005 and 3.27 (3.18-3.36) for cohort 2010 in schizophrenia, and 2.65 (95% CI: 2.55-2.76) for cohort 2005 and 2.39 (2.31-2.48) for cohort 2010 in bipolar disorder, respectively. The SMRs in people with depression were 1.83 (95% CI: 1.81-1.86) for cohort 2005 and 1.59 (1.57-1.61) for cohort 2010. SMRs due to unnatural causes tended to decrease in people with major mental illnesses over the years, but those due to natural causes remained relatively stable. The life expectancies at birth for schizophrenia, bipolar disorder and depression were all significantly lower than the national norms, specifically showing 14.97-15.50 years of life lost for men and 15.15-15.48 years for women in people with schizophrenia. CONCLUSIONS: Compared to general population, the differential in mortality rates for people with major mental illnesses persisted substantial. The differential in mortality for unnatural causes of death seemed decreasing over the years, but that due to natural causes remained relatively steady. Regardless of gender, people with schizophrenia, bipolar disorder and depression were shown to have shortened life expectancies compared to general population.

Potential gains in life expectancy from reducing amenable mortality among people diagnosed with serious mental illness in the United Kingdom.

BACKGROUND: To estimate the potential gain in life expectancy from addressing modifiable risk factors for all-cause mortality (excluding suicide and deaths from accidents or violence) across specific serious mental illness (SMI) subgroups, namely schizophrenia, schizoaffective disorders, and bipolar disorders in a Western population. METHODS: We have used relative risks from recent meta-analyses to estimate the population attribution fraction (PAF) due to specific modifiable risk factors known to be associated with all-cause mortality within SMI. The potential gain in life expectancy at birth, age 50 and age 65 years were assessed by estimating the combined effect of modifiable risk factors from different contextual levels (behavioural, healthcare, social) and accounting for the effectiveness of existing interventions tackling these factors. Projections for annual gain in life expectancy at birth during a two-decade was estimated using the Annual Percentage Change (APC) formula. The predicted estimates were based on mortality rates for year 2014-2015. RESULTS: Based on the effectiveness of existing interventions targeting these modifiable risk factors, we estimated potential gain in life expectancy at birth of four (bipolar disorders), six (schizoaffective disorders), or seven years (schizophrenia). The gain in life expectancy at age 50 years was three (bipolar disorders) or five (schizophrenia and schizoaffective disorders) years. The projected gain in life expectancy at age 65 years was three (bipolar disorders) or four (schizophrenia and schizoaffective disorders) years. CONCLUSIONS: The implementation of existing interventions targeting modifiable risk factors could narrow the current mortality gap between the general and the SMI populations by 24% (men) to 28% (women). These projections represent ideal circumstances and without the limitation of overestimation which often comes with PAFs.

Trauma-related mortality of patients with severe psychiatric disorders: population-based study from the French national hospital database.

BACKGROUND: Most research on mortality in people with severe psychiatric disorders has focused on natural causes of death. Little is known about trauma-related mortality, although bipolar disorder and schizophrenia have been associated with increased risk of self-administered injury and road accidents. AIMS: To determine if 30-day in-patient mortality from traumatic injury was increased in people with bipolar disorder and schizophrenia compared with those without psychiatric disorders. METHOD: A French national 2016 database of 144 058 hospital admissions for trauma was explored. Patients with bipolar disorder and schizophrenia were selected and matched with mentally healthy controls in a 1:3 ratio according to age, gender, social deprivation and region of residence. We collected the following data: sociodemographic characteristics, comorbidities, trauma severity characteristics and trauma circumstances. Study outcome was 30-day in-patient mortality. RESULTS: The study included 1059 people with bipolar disorder, 1575 people with schizophrenia and their respective controls (n = 3177 and n = 4725). The 30-day mortality was 5.7% in bipolar disorder, 5.1% in schizophrenia and 3.3 and 3.8% in the controls, respectively. Only bipolar disorder was associated with increased mortality in univariate analyses. This association remained significant after adjustment for sociodemographic characteristics and comorbidities but not after adjustment for trauma severity. Self-administered injuries were associated with increased mortality independent of the presence of a psychiatric diagnosis. CONCLUSIONS: Patients with bipolar disorder are at higher risk of 30-day mortality, probably through increased trauma severity. A self-administered injury is predictive of a poor survival prognosis regardless of psychiatric diagnosis.

Clozapine: promising treatment for suicidality in bipolar disorder.

Bipolar disorder is associated with the highest risk of completed suicide of all mental disorders. The suicide mortality of people with bipolar disorder is approximately 25 times higher than the general population. No approved pharmacological strategies for suicidality in bipolar disorder have been introduced so far. There is evidence for anti-suicidal effect of clozapine in schizophrenia. Clozapine with its unique pharmacology, anti-aggressive and anti-impulsive properties is potentially an effective strategy for suicidality in bipolar disorder.

Mortality and Medical Comorbidity in the Severely Mentally Ill.

BACKGROUND: Mentally ill patients die on average 10 years earlier than the general population, largely due to general medical disorders. This study is the first to explore in a large German sample the prevalence, mortality, and medical comorbidity in pa- tients with severe mental illness (SMI). The patients were affected by borderline personality disorder (BPD), psychotic disorders, bipolar disorder, or severe unipolar depression. METHODS: Our database consists of billing data from all adults with statutory health insurance in Germany. Twelve-month administrative SMI prevalence and medical comorbidity were estimated using cross-sectional data from 2016 (age ≥ 18; N = 59 561 310). Two-year mortality was established longitudinally in a randomly selected subset of the billing data (most recent mortality information available for 2012 to 2014; 2012: n = 15 590 107). RESULTS: Severe unipolar depression had the highest prevalence (2.01%), followed by psychotic disorders (1.25%), BPD (0.34%), and bipolar disorder (0.29%). While the prevalence of malignant neoplasms showed moderate deviations from reference values [severe unipolar depression: OR = 1.30 (95% CI = 1.29; 1.31), BPD: OR = 1.11 (1.09; 1.14), psychotic dis- orders: OR = 0.90 (0.89; 0.90), bipolar disorder: OR = 1.07 (1.06; 1.09)], other disease groups (infectious, endocrine/nutritional/ metabolic, circulatory, respiratory) were substantially elevated in all categories of SMI. Mortality rates for psychotic disorders, BPD, bipolar disorder, and severe unipolar depression were increased (OR = 2.38 [95% CI=2.32; 2.44], 2.30 [2.08; 2.54], 1.52 [1.42; 1.62], and 1.40 [1.37; 1.44], respectively), with a loss of 2.6 to 12.3 years, depending on age, sex, and SMI. CONCLUSION: Mortality is substantially elevated in all SMI patients. The results underline the need to remove barriers to adequate general medical care, both on the patient and the provider side, to reduce excess mortality.

Diagnosed Mental Health Conditions and Risk of Suicide Mortality.

OBJECTIVE: Although mental health conditions are risk factors for suicide, limited data are available on suicide mortality associated with specific mental health conditions in the U.S. population. This study aimed to fill this gap. METHODS: This study used a case-control design. Patients in the case group were those who died by suicide between 2000 and 2013 and who were patients in eight health care systems in the Mental Health Research Network (N=2,674). Each was matched with 100 general population patients from the same system (N=267,400). Diagnostic codes for five mental health conditions in the year before death were obtained from medical records: anxiety disorders, attention deficit-hyperactivity disorder (ADHD), bipolar disorder, depressive disorders, and schizophrenia spectrum disorder. RESULTS: Among patients in the case group, 51.3% had a recorded psychiatric diagnosis in the year before death, compared with 12.7% of control group patients. Risk of suicide mortality was highest among those with schizophrenia spectrum disorder, after adjustment for age and sociodemographic characteristics (adjusted odds ratio [AOR]=15.0) followed by bipolar disorder (AOR=13.2), depressive disorders (AOR=7.2), anxiety disorders (AOR=5.8), and ADHD (AOR=2.4). The risk of suicide death among those with a diagnosed bipolar disorder was higher in women than men. CONCLUSIONS: Half of those who died by suicide had at least one diagnosed mental health condition in the year before death, and most mental health conditions were associated with an increased risk of suicide. Findings suggest the importance of suicide screening and providing an approach to improve awareness of mental health conditions.

Undiagnosed cardiovascular disease prior to cardiovascular death in individuals with severe mental illness.

OBJECTIVE: To examine whether individuals with schizophrenia (SCZ) or bipolar disorder (BD) had equal likelihood of not being diagnosed with cardiovascular disease (CVD) prior to cardiovascular death, compared to individuals without SCZ or BD. METHODS: Multivariate logistic regression analysis including nationwide data of 72 451 cardiovascular deaths in the years 2011-2016. Of these, 814 had a SCZ diagnosis and 673 a BD diagnosis in primary or specialist health care. RESULTS: Individuals with SCZ were 66% more likely (OR: 1.66; 95% CI: 1.39-1.98), women with BD were 38% more likely (adjusted OR: 1.38; 95% CI: 1.04-1.82), and men with BD were equally likely (OR: 0.88, 95% CI: 0.63-1.24) not to be diagnosed with CVD prior to cardiovascular death, compared to individuals without SMI. Almost all (98%) individuals with SMI and undiagnosed CVD had visited primary or specialized somatic health care prior to death, compared to 88% among the other individuals who died of CVD. CONCLUSION: Individuals with SCZ and women with BD are more likely to die due to undiagnosed CVD, despite increased risk of CVD and many contacts with primary and specialized somatic care. Strengthened efforts to prevent, recognize, and treat CVD in individuals with SMI from young age are needed.

Increasing mortality gap for patients diagnosed with bipolar disorder-A nationwide study with 20 years of follow-up.

OBJECTIVES: The primary aim of this study was to examine whether the mortality of patients with bipolar disorder has increased over the past two decades as compared with the background population. METHODS: All patients registered with a bipolar disorder diagnosis in the Danish Psychiatric Research Registry from 1965 until the end of 2014, living in Denmark, alive and below the age of 65 years in the study period from 1995 to 2014 were included. Included patients reaching the age of 65 years during the study period were censored at that time point. Overall standardized mortality ratios (SMRs) were calculated for each calendar year over the study period, and trends in SMR over the study period were examined using linear regression. In addition, the SMRs were stratified according to age groups. RESULTS: Patients with bipolar disorder had an overall elevated mortality rate relative to the general population with an SMR of 2.8, 95% confidence interval (CI): 2.8-2.9. The highest SMR was found among the youngest (15-29 years: 8.2, 95% CI: 6.7-10.1; 30-34 years: 7.7, 95% CI: 6.4-9.3; 35-39 years: 6.2, 95% CI: 5.4-7.2; 40-44 years: 4.6, 95% CI: 4.1-5.1; 45-49 years: 3.5, 95% CI: 3.3-3.8; 50-54 years: 3.2, 95% CI: 3.0-3.4; 55-59 years: 2.7, 95% CI: 2.6-2.8; and 60-64 years: 2.2, 95% CI: 2.1-2.3). An increase in SMR of 0.03 per year in patients diagnosed with bipolar disorder (P < 0.01) was found. CONCLUSIONS: The mortality gap between patients with bipolar disorder and the general Danish population has widened over the past two decades, which is a cause for concern, although reasons for the increasing mortality gap are unknown.

Healthcare cost, service use and mortality in major psychiatric disorders in Taiwan.

BACKGROUND: We aimed to examine the differences in the cost distributions, service use, and mortality outcomes, across major psychiatric disorders in Taiwan. METHOD: A national cohort of adult patients (n = 68,068) who had newly received a diagnosis of schizophrenia, bipolar disorder, and major depressive disorder (MDD) was identified from the National Health Insurance Research Database and followed for the subsequent three years. Variations in the 1-year and 3-year healthcare cost distributions and mortality outcomes were examined according to age group (18-64 years, ≥65 years) and diagnosis. RESULTS: Regardless of age group, individuals with schizophrenia had the highest total and psychiatric healthcare costs. Healthcare costs for psychiatric services accounted for 84.25%, 60%, and 29.62% of the 1-year total healthcare costs for younger patients with a diagnosis of schizophrenia, bipolar disorder, and MDD, respectively. Psychiatric inpatient care costs constituted a major part of the 1-year psychiatric healthcare costs, e.g., 85.86% for schizophrenia patients aged 18-64 years, while psychiatric medication costs contributed to a relatively smaller part. For those older than 65 years, costs of other specialties for comorbid physical conditions were more prominent. LIMITATIONS: The perspective of the current analysis was limited to healthcare services, and we were not able to analyse wider economic impacts. CONCLUSIONS: Psychiatric inpatient care costs contributed to a significant share of psychiatric expenditures, emphasizing the need of developing strategies to reduce rehospitalisations. For those aged 65 years or older, efforts to improve interdisciplinary service care for comorbid physical conditions may be required.

Cost-effectiveness and cost-utility analysis of outpatient follow-up frequency in relation to three-year mortality in discharged patients with bipolar disorder.

There is a lack of clarity in terms of cost-effectiveness and cost-utility comparisons across different outpatient (OPD) follow-up patterns in discharged patients with bipolar disorder (BD). In this study, adult patients hospitalised for BD treatment (n = 1,591) were identified from the National Health Insurance Research Database in Taiwan. With survival as the effectiveness measure and quality-adjusted life years (QALYs) as the utility measure, a cost-effectiveness and cost-utility analysis was conducted over the 3-year follow-up period by post-discharge frequency of OPD visits. Compared to those making 1-7, 8-12 and 18 or more OPD visits, BD patients making 13-17 OPD visits within the first year after discharge had the lowest psychiatric and total healthcare costs over the follow-up period. With survival status as the effectiveness outcome, making 13-17 OPD visits was more likely to be the cost-effective option, as revealed by incremental cost-effectiveness ratios. Cost-utility analysis demonstrated that having 13-17 OPD visits was probably the more cost-effective option when considering QALYs; for instance, if society was willing to pay NTD1.5 million for one additional QALY, there was a 75.2% (psychiatric costs) to 77.4% (total costs) likelihood that 13-17 OPD visits was the most cost-effective option. In conclusion, post-discharge OPD appointments with a frequency of 13-17 visits within the first year were associated with lower psychiatric and total healthcare costs in the subsequent 3 years. Having an adequate outpatient follow-up frequency was likely to be cost-effective in the management of discharged patients with BD in this real-world setting.

Estudio comparativo sobre las causas de mortalidad entre personas con trastorno bipolar y una muestra control en Costa Rica entre 1995 y 2005 / Comparative study of mortality causes between subjects with bipolar disorder and a control sample between 1995 and 2005

Resumen Justificación: el trastorno afectivo bipolar afecta entre un 1 % y un 2 % de la población mundial. Se ha descrito que se acompaña de un aumento en la mortalidad por causas tanto violentas como no violentas. Existen pocos estudios en el país acerca de las causas de muerte en esta población. Este estudio tiene como objetivo analizar las causas de muerte de personas con trastorno afectivo bipolar y compararlas con las de controles sanos. Métodos: de los sujetos con trastorno afectivo bipolar previamente reclutados para estudios genéticos del Centro de Investigación en Biología Celular y Molecular de la UCR, se seleccionó a las 154 personas que habían fallecido entre 1993 y 2005. Se eligieron 154 controles apareados por sexo, que hubiesen nacido y fallecido en el mismo periodo que el sujeto, con una diferencia no mayor a tres meses. El análisis estadístico consistió en una prueba exacta de Fisher con 1000 simulaciones del valor de p con Monte Carlo. Resultados: de los 154 sujetos, un 50 % (n=77) fueron mujeres. No hubo diferencia en la causa de muerte entre sexos. Se encontró diferencia significativa en las principales causas de muerte entre casos y controles (p<0,05). Se observó una diferencia significativa en las categorías de "lesiones autoinflingidas" (χ2 (1)=11.0, p<0,05) y "cáncer" (χ2(1)= 4,1, p= 0,04). No se documentó diferencia en enfermedad cardiovascular (χ2(1)=0,3, p= 0,61), neumonía (χ2(1)=3,1, p= 0,07) y accidentes (χ2(1)= 2,0, p= 0,16). Conclusión: como se ha documentado en bibliografía internacional, las lesiones autoinfligidas son la causa de muerte de mayor importancia en la población afectada con trastorno afectivo bipolar.

Abstract Background: Bipolar disorder affects 1% to 2% of the world population. It has been described that it is accompanied by an increase in mortality from both violent and non-violent causes. Few studies have been published in our country about causes of death in this particular population. The objective of our study is to analyze the causes of death of subjects with bipolar disorder and compare them to healthy controls. Methods: From the pool of subjects with bipolar disorder previously recruited for genetic studies conducted at the Cellular and Molecular Biology Research Centre of the UCR, we recruited the 154 subjects who had died between 1993 and 2005. Controls of the same sex who were born and died in the same period as the subject, with a difference no greater than three months, were selected. For the statistical analysis we ran a Fisher's exact test with 1000 simulations of the p-value with Monte Carlo. Results: Of 154 subjects, 50% (n=77) were women. We found no difference in the cause of death between sexes among the cases. A significant difference in the main causes of death was found between cases and controls (p<0.05). A significant difference was observed in the categories of "self-inflicted lesions" (χ2 (1)=11.0, p<0.05) and "cancer" (χ2(1)= 4.1, p= 0.04). No difference was documented in cardiovascular disease, (χ2(1)=0.3, p= 0.61), pneumonia (χ2(1)=3.1, p= 0.07) nor accidents (χ2(1)= 2.0, p= 0.16). Conclusion: Self-inflicted lesions, as has been documented in international literature, are a cause of death of major importance in the population affected with bipolar disorder.

Older men with bipolar disorder: Clinical associations with early and late onset illness.

OBJECTIVES: Older adults living with bipolar disorder (BD) include people with early and late onset of symptoms. This study aimed to clarify the cross-sectional and longitudinal clinical associations of BD with early and late onset. METHODS: Cohort study of 38 173 men aged 65-85 years followed for up to 17.6 years. We used the Western Australian Data Linkage System to establish the presence of BD, as well as diabetes, cardiovascular and renal diseases, cancer, respiratory and gastrointestinal diseases, alcohol use disorder, dementia, and mortality. The causes of death were recorded according to the International Classification of Diseases. We defined late onset BD using 2 different cut-points: 50 and 60 years. RESULTS: The prevalence of medical morbidities was greater among participants with than without BD, and cardiovascular diseases were more frequent among those with onset before than after 50 years (odds ratio = 1.72, 95% confidence interval = 1.01, 2.94). Bipolar disorder was associated with increased hazard ratio of dementia and death, but there was no difference between early and late onset participants. Death by suicide or accidents occurred exclusively among BD participants with illness onset <60 years, whereas death associated with strokes and neurodegenerative diseases was more frequent among those with illness onset ≥60 years than in the general population (HR = 2.28, 95% confidence interval = 1.34, 3.88). CONCLUSIONS: Our results indicate that the clinical associations and outcomes of older adults living with BD are not markedly influenced by age of onset. However, mortality data suggest that differences between older adults with BD onset before and after age 60 years should continue to be explored.

Psychiatric comorbidity increases mortality in immune-mediated inflammatory diseases.

OBJECTIVE: We determined the association between any common mental disorder (CMD: depression, anxiety disorder, bipolar disorder) and mortality and suicide in three immune-mediated inflammatory diseases (IMID), inflammatory bowel disease (IBD), multiple sclerosis (MS) and rheumatoid arthritis (RA), versus age-, sex- and geographically-matched controls. METHODS: Using administrative data, we identified 28,384 IMID cases (IBD: 8695; MS: 5496; RA: 14,503) and 141,672 matched controls. We determined annual rates of mortality, suicide and suicide attempts. We evaluated the association of any CMD with all-cause mortality and suicide using multivariable Cox regression models. RESULTS: In the IMID cohort, any CMD was associated with increased mortality. We observed a greater than additive interaction between depression and IMID status (attributable proportion 5.2%), but a less than additive interaction with anxiety (attributable proportion -13%). Findings were similar for MS and RA. In IBD, a less than additive interaction existed with depression and anxiety on mortality risk. The IMID cohort with any CMD had an increased suicide risk versus the matched cohort without CMD. CONCLUSION: CMD are associated with increased mortality and suicide risk in IMID. In MS and RA, the effects of depression on mortality risk are greater than associations of these IMID and depression alone.

Long-term antipsychotic polypharmacy prescribing in secondary mental health care and the risk of mortality.

OBJECTIVES: To investigate the association between long-term antipsychotic polypharmacy use and mortality; and determine whether this risk varies by cause of death and antipsychotic dose. METHODS: Using data from a large anonymised mental healthcare database, we identified all adult patients with serious mental illness (SMI) who had been prescribed a single antipsychotic or polypharmacy, for six or more months between 2007 and 2014. Multivariable Cox regression models were constructed, adjusting for sociodemographic, socioeconomic, clinical factors and smoking, to examine the association between APP use and the risk of death. RESULTS: We identified 10 945 adults with SMI who had been prescribed long-term antipsychotic monotherapy (76.9%) or APP (23.1%). Patients on long-term APP had a small elevated risk of mortality, which was significant in some but not all models. The adjusted hazard ratios for death from natural and unnatural causes associated with APP were 1.2 (0.9-1.4, P = 0.111) and 1.1 (0.7-1.9, P = 0.619) respectively. The strengths of the associations between APP and mortality outcomes were similar after further adjusting for % BNF antipsychotic dose (P = 0.031) or olanzapine equivalence (P = 0.088). CONCLUSION: The findings suggest that the effect of long-term APP on mortality is not clear-cut, with limited evidence to indicate an association, even after controlling for the effect of dose.

Closing the mortality gap for severe mental illness: are we going in the right direction?

In this editorial, we discuss a UK-based cohort study examining the mortality gap for people with schizophrenia and bipolar disorder from 2000 to 2014. There have been concerted efforts to improve physical and mental healthcare for this population in recent decades. Have these initiatives reduced mortality and 'closed the gap'?

Psychiatric conditions as predictors of rehospitalization among African American patients hospitalized with heart failure.

INTRODUCTION: African Americans (AAs) have the highest risk of developing heart failure (HF) among all ethnicities in the United States and are associated with higher rates of readmissions and mortality. This study aims to determine the prevalence and relationship of common psychiatric conditions to outcomes of patients hospitalized with HF. HYPOTHESIS: Psychiatric conditions lead to worse outcomes in HF patients. METHODS: This single-center retrospective study enrolled 611 AA patients admitted to an urban teaching community hospital for HF from 2010 to 2013. Patient demographics, clinical variables, and history of psychiatric disorders were obtained. Cox proportional hazards regression was used to assess impact of psychiatric disorders on readmission rates and mortality. RESULTS: The mean age was 66 ± 15 years; 53% were men. Median follow-up time from index admission for HF was 3.2 years. Ninety-seven patients had a psychiatric condition: 46 had depression, 11 had bipolar mood disorder (BMD), and 40 had schizophrenia. After adjustment of known risk factors and clinical metrics, our study showed that AA HF patients with a psychiatric illness were 3.84× more likely to be admitted within 30 days for HF, compared with those without (P < 0.001). Individually, adjusted Cox multivariable logistic regression analysis also showed that, for 30-day readmission, schizophrenia had a hazard ratio (HR) of 4.92 (P < 0.001); BMD, an HR of 3.44 (P = 0.02); and depression, an HR 3.15 (P = 0.001). No associations were found with mortality. CONCLUSIONS: Psychiatric conditions of schizophrenia, BMD, and depression were significantly associated with a higher 30-day and overall readmission rate for HF among AA patients.

Mortality gap for people with bipolar disorder and schizophrenia: UK-based cohort study 2000-2014.

BackgroundBipolar disorder and schizophrenia are associated with increased mortality relative to the general population. There is an international emphasis on decreasing this excess mortality.AimsTo determine whether the mortality gap between individuals with bipolar disorder and schizophrenia and the general population has decreased.MethodA nationally representative cohort study using primary care electronic health records from 2000 to 2014, comparing all patients diagnosed with bipolar disorder or schizophrenia and the general population. The primary outcome was all-cause mortality.ResultsIndividuals with bipolar disorder and schizophrenia had elevated mortality (adjusted hazard ratio (HR) = 1.79, 95% CI 1.67-1.88 and 2.08, 95% CI 1.98-2.19 respectively). Adjusted HRs for bipolar disorder increased by 0.14/year (95% CI 0.10-0.19) from 2006 to 2014. The adjusted HRs for schizophrenia increased gradually from 2004 to 2010 (0.11/year, 95% CI 0.04-0.17) and rapidly after 2010 (0.34/year, 95% CI 0.18-0.49).ConclusionsThe mortality gap between individuals with bipolar disorder and schizophrenia, and the general population is widening.
