Context Despite improvements in mental health services in recent decades, it is unclear whether the risk of mortality in schizophrenia has changed over time. Objective To explore the distribution of standardized mortality ratios (SMRs) for people with schizophrenia. Data Sources Broad search terms were used in MEDLINE, PsychINFO, Web of Science, and Google Scholar to identify all studies that investigated mortality in schizophrenia, published between January 1, 1980, and January 31, 2006. References were also identified from review articles, reference lists, and communication with authors. Study Selection Population-based studies that reported primary data on deaths in people with schizophrenia. Data Extraction Operationalized criteria were used to extract key study features and mortality data. Data Synthesis We examined the distribution of SMRs and pooled selected estimates using random-effects meta-analysis. We identified 37 articles drawn from 25 different nations. The median SMR for all persons for all-cause mortality was 2.58 (10%-90% quantile, 1.18-5.76), with a corresponding random-effects pooled SMR of 2.50 (95% confidence interval, 2.18-2.43). No sex difference was detected. Suicide was associated with the highest SMR (12.86); however, most of the major causes-of-death categories were found to be elevated in people with schizophrenia. The SMRs for all-cause mortality have increased during recent decades (P = .03). Conclusions With respect to mortality, a substantial gap exists between the health of people with schizophrenia and the general community. This differential mortality gap has worsened in recent decades. In light of the potential for second-generation antipsychotic medications to further adversely influence mortality rates in the decades to come, optimizing the general health of people with schizophrenia warrants urgent attention.

A systematic review of mortality in schizophrenia: is the differential mortality gap worsening over time?

Importance Despite the potential importance of understanding excess mortality among people with mental disorders, no comprehensive meta-analyses have been conducted quantifying mortality across mental disorders. Objective To conduct a systematic review and meta-analysis of mortality among people with mental disorders and examine differences in mortality risks by type of death, diagnosis, and study characteristics. Data sources We searched EMBASE, MEDLINE, PsychINFO, and Web of Science from inception through May 7, 2014, including references of eligible articles. Our search strategy included terms for mental disorders (eg, mental disorders, serious mental illness, and severe mental illness), specific diagnoses (eg, schizophrenia, depression, anxiety, and bipolar disorder), and mortality. We also used Google Scholar to identify articles that cited eligible articles. Study selection English-language cohort studies that reported a mortality estimate of mental disorders compared with a general population or controls from the same study setting without mental illness were included. Two reviewers independently reviewed the titles, abstracts, and articles. Of 2481 studies identified, 203 articles met the eligibility criteria and represented 29 countries in 6 continents. Data extraction and synthesis One reviewer conducted a full abstraction of all data, and 2 reviewers verified accuracy. Main outcomes and measures Mortality estimates (eg, standardized mortality ratios, relative risks, hazard ratios, odds ratios, and years of potential life lost) comparing people with mental disorders and the general population or people without mental disorders. We used random-effects meta-analysis models to pool mortality ratios for all, natural, and unnatural causes of death. We also examined years of potential life lost and estimated the population attributable risk of mortality due to mental disorders. Results For all-cause mortality, the pooled relative risk of mortality among those with mental disorders (from 148 studies) was 2.22 (95% CI, 2.12-2.33). Of these, 135 studies revealed that mortality was significantly higher among people with mental disorders than among the comparison population. A total of 67.3% of deaths among people with mental disorders were due to natural causes, 17.5% to unnatural causes, and the remainder to other or unknown causes. The median years of potential life lost was 10 years (n = 24 studies). We estimate that 14.3% of deaths worldwide, or approximately 8 million deaths each year, are attributable to mental disorders. Conclusions and relevance These estimates suggest that mental disorders rank among the most substantial causes of death worldwide. Efforts to quantify and address the global burden of illness need to better consider the role of mental disorders in preventable mortality.

Mortality in Mental Disorders and Global Disease Burden Implications: A Systematic Review and Meta-analysis

Importance High rates of suicide after psychiatric hospitalization are reported in many studies, yet the magnitude of the increases and the factors underlying them remain unclear. Objectives To quantify the rates of suicide after discharge from psychiatric facilities and examine what moderates those rates. Data Sources English-language, peer-reviewed publications published from January 1, 1946, to May 1, 2016, were located using MEDLINE, PsychINFO, and EMBASE with the search terms (( suicid *). ti AND ( hospital or discharg * OR inpatient or in-patient OR admit *) .ab and (( mortality OR outcome * OR death *) AND ( psych * OR mental *)). ti AND ( admit * OR admis * or hospital * OR inpatient * OR in-patient * OR discharg *). ab . Hand searching was also done. Study Selection Studies reporting the number of suicides among patients discharged from psychiatric facilities and the number of exposed person-years and studies from which these data could be calculated. Data Extraction and Synthesis The meta-analysis adhered to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. A random-effects model was used to calculate a pooled estimate of postdischarge suicides per 100 000 person-years. Main Outcomes and Measures The suicide rate after discharge from psychiatric facilities was the main outcome, and the association between the duration of follow-up and the year of the sampling were the main a priori moderators. Results A total of 100 studies reported 183 patient samples (50 samples of females, 49 of males, and 84 of mixed sex; 129 of adults or unspecified patients, 20 of adolescents, 19 of older patients, and 15 from long-term or forensic discharge facilities), including a total of 17 857 suicides during 4 725 445 person-years. The pooled estimate postdischarge suicide rate was 484 suicides per 100 000 person-years (95% CI, 422-555 suicides per 100 000 person-years; prediction interval, 89-2641), with high between-sample heterogeneity ( I 2  = 98%). The suicide rate was highest within 3 months after discharge (1132; 95% CI, 874-1467) and among patients admitted with suicidal ideas or behaviors (2078; 95% CI, 1512-2856). Pooled suicide rates per 100 000 patients-years were 654 for studies with follow-up periods of 3 months to 1 year, 494 for studies with follow-up periods of 1 to 5 years, 366 for studies with follow-up periods of 5 to 10 years, and 277 for studies with follow-up periods longer than 10 years. Suicide rates were higher among samples collected in the periods 1995-2004 (656; 95% CI, 518-831) and 2005-2016 (672; 95% CI, 428-1055) than in earlier samples. Conclusions and Relevance The immediate postdischarge period is a time of marked risk, but rates of suicide remain high for many years after discharge. Patients admitted because of suicidal ideas or behaviors and those in the first months after discharge should be a particular focus of concern. Previously admitted patients should be able to access long-term care and assistance.

Suicide Rates After Discharge From Psychiatric Facilities: A Systematic Review and Meta-analysis

Age and gender

Background
Several antipsychotic agents are known to prolong the QT interval in a dose dependent manner. Corrected QT interval (QTc) exceeding a threshold value of 450 ms may be associated with an increased risk of life threatening arrhythmias. Antipsychotic agents are often given in combination with other psychotropic drugs, such as antidepressants, that may also contribute to QT prolongation. This observational study compares the effects observed on QT interval between antipsychotic monotherapy and psychoactive polytherapy, which included an additional antidepressant or lithium treatment.

QT interval prolongation related to psychoactive drug treatment: a comparison of monotherapy versus polytherapy

BACKGROUND: Mental disorders have an increased mortality risk. However, most data have been provided by few countries, some mental disorders have received little attention, long-term studies of large samples are scarce, and insufficient control for confounding variables has lead to artefactual inconsistencies across studies. The aims of this study were: to quantify the mortality risk in psychiatric patients 5 to 21 years after hospital admission and to investigate temporal trends in mortality risk and predictive factors associated with mortality. METHOD: All patients admitted to an in-patient psychiatric unit in Italy between 1978 and 1994 were included and vital status and death causes were determined up to 21 years after admission. The observed number of deaths in the sample was compared with the expected number of deaths in the general population. Cox proportional hazard models were fitted to identify predictors of mortality. RESULTS: Mortality from natural and unnatural causes was higher than expected across all mental disorders. Standardized mortality risk was higher in males (SMR = 4.55; 95% CI 4.17-4.97) than in females (SMR = 3.43; 95% CI 3.07-3.83). Individuals aged less than 40 years were at higher risk in both sexes. The first several years following admission were characterized by a faster decline in survival. Several demographic and clinical factors were predictors of mortality. CONCLUSIONS: Mortality is high in individuals with mental disorders. Prevention of unnatural death causes is an important goal though insufficient to abate excess mortality, since natural death causes account for it to a larger extent. Language: en
