Functional status and all-cause mortality in serious mental illness

Exploring the Experience of Community Participation Among Individuals With Serious Mental Illness

People with serious mental illness (SMI) encounter restrictions in the quantity of their community participation. Less is known about the quality of their participation. We aimed to explore the relationship between symptoms of SMI and the daily experience (i.e., loneliness and enjoyment) of community participation. We examined daily community participation among people with SMI using ecological momentary assessment surveys. We built multilevel models to examine the associations between symptoms of SMI and loneliness or enjoyment during community participation. Our analysis included 183 people among four participant groups: bipolar disorder (n = 44), major depressive disorder (n = 46), schizophrenia/schizoaffective disorder (n = 40), and control (n = 53). People with schizophrenia engaged in more unstructured activities (e.g., socializing) than people among other groups. Symptom association varied across diagnostic groups. To support tailored intervention development, researchers and practitioners should consider the context of participation and the clinical characteristics of the client.

Is antipsychotic augmentation associated with improved functioning in patients on clozapine?

OBJECTIVE

We aimed at exploring the relationship between functional outcomes in patients on clozapine augmented with antipsychotics in treatment-resistant schizophrenia using standard outcome measures Health of Nation Outcome Scales (HoNOS) and Life Skills Profile (LSP-16).

METHOD

In a cross-sectional study of 83 patients on clozapine treated in a psychiatric rehabilitation hospital, the association between the primary outcome measure, LSP-16 including its subscales, and treatment with antipsychotic augmentation (AA) were analysed using linear regression.

RESULT

The presence of moderate-to-severe positive symptoms on the HoNOS 6 dichotomised item measure was the only statistically significant predictor of functional impairment as determined by total LSP-16 score.The group of patients with ongoing positive symptoms (partial responders) were characterised by higher total LSP-16 scores, higher numbers of AA agents, and higher chlorpromazine equivalence. There was an inverse linear relationship between chlorpromazine equivalence of AA and total score of LSP-16 scale in the group of partial responders.

CONCLUSION

Augmentation with other antipsychotic agents was associated with higher functioning in a cross-sectional study of patients with schizophrenia with poor response of positive symptoms to clozapine. This might be an important clinical factor to consider when prescribing antipsychotics to patients with clozapine-resistant schizophrenia.

Lower odds of successful community discharge after medical hospitalization for Veterans with schizophrenia: A retrospective cohort study of national data

Medical comorbidity, particularly cardiovascular diseases, contributes to high rates of hospital admission and early mortality in people with schizophrenia. The 30 days following hospital discharge represents a critical period for mitigating adverse outcomes. This study examined the odds of successful community discharge among Veterans with schizophrenia compared to those with major affective disorders and those without serious mental illness (SMI) after a heart failure hospital admission. Data for Veterans hospitalized for heart failure were obtained from the Veterans Health Administration (VHA) and Centers for Medicare & Medicaid Services between 2011 and 2019. Psychiatric diagnoses and medical comorbidities were assessed in the year prior to hospitalization. Successful community discharge was defined as remaining in the community without hospital readmission, death, or hospice for 30 days after hospital discharge. Logistic regression analyses adjusting for relevant factors were used to examine whether individuals with a schizophrenia diagnosis showed lower odds of successful community discharge versus both comparison groups. Out of 309,750 total Veterans in the sample, 7377 (2.4%) had schizophrenia or schizoaffective disorder and 32,472 (10.5%) had major affective disorders (bipolar disorder or recurrent major depressive disorder). Results from adjusted logistic regression analyses demonstrated significantly lower odds of successful community discharge for Veterans with schizophrenia compared to the non-SMI (Odds Ratio [OR]: 0.63; 95% Confidence Interval [CI]: 0.60, 0.66) and major affective disorders (OR: 0.65, 95%; CI: 0.62, 0.69) groups. Intervention efforts should target the transition from hospital to home in the subgroup of Veterans with schizophrenia.

Risk factors for mortality in patients admitted to a psychiatric acute ward: A prospective cohort study

INTRODUCTION

Associations between psychiatric disorders and mortality have been extensively studied, but limited evidence exists regarding influence of clinical characteristics on mortality risk, at the time of acute psychiatric hospitalization.

METHODS

A prospective total-cohort study included all patients consecutively admitted to Haukeland University Hospital's psychiatric acute ward in Bergen, Norway between 2005 and 2014 (n = 6125). Clinical interviews were conducted at the first admission within the study period, and patients were subsequently followed for up to 15 years in the Norwegian Cause of Death Registry. Competing risks regression models were used to investigate associations between clinical characteristics at first admission and the risk of natural and unnatural death during follow-up.

RESULTS

The mean age at first admission and at time of death was 42.5 and 62.8 years, respectively, and the proportion of women in the sample was 47.2%. A total of 1381 deaths were registered during follow-up, of which 65.5% had natural, 30.4% unnatural, and 4.1% unknown causes. Higher age, male sex, unemployment, cognitive deficits, and physical illness were associated with increased risk of natural death. Male sex, having no partner, physical illness, suicide attempts, and excessive use of alcohol and illicit substances were associated with increased risk of unnatural death.

CONCLUSION

Psychiatric symptoms, except suicide attempts, were unrelated to increased mortality risk. In the endeavor to reduce the increased mortality risk in people with mental disorders, focus should be on addressing modifiable risk factors linked to physical health and excessive use of alcohol and illicit substances.

The association between area-level factors and mortality in severe mental illnesses: A systematic review

BACKGROUND

Premature mortality is a well-documented adverse outcome for people living with severe mental illnesses (SMI). Emerging evidence suggests that area-level factors play a role that are experienced disproportionately by this population. This review assesses the potential association between area-level factors and mortality in people with SMI.

METHOD

We searched Medline, EMBASE, PsychINFO, Social Policy and Practice, Web of Science and OpenGrey databases. Literature searches were conducted in May 2020 and updated in June 2023. Reference lists were hand-searched and authors of included studies contacted to identify additional studies and minimise publication biases. Narrative synthesis was used to appraise the included studies. The review protocol was registered on PROSPERO (CRD42019155447).

RESULTS

Our searches identified 7 studies (8 papers), which were included in the review, and indicated evidence of an association between deprivation and mortality. One study suggested an association between mortality in SMI and urbanicity in low to middle income settings which was not observed in studies from high income settings. One study suggested a protective association of area-level ethnic density with mortality within urbanised settings.

CONCLUSION

Consistent associations were reported between residence in areas of higher deprivation and increased risk of mortality in SMI. Two studies suggested an association between area-level ethnic density and urbanicity and mortality in SMI. Most studies were conducted across high income countries and therefore future research could benefit from similar investigations being conducted in low- and middle-income countries. These methods would inform health and social policies, including interventions to reduce premature mortality in SMI.

The Role of Socioeconomic Position in the Association Between Mental Disorders and Mortality: A Systematic Review and Meta-Analysis

Importance

Studies are lacking summarizing how the association between mental disorders and mortality varies by socioeconomic position (SEP), particularly considering different aspects of SEP, specific types of mental disorders, and causes of death.

Objective

To investigate the role of SEP in the association between mental disorders and mortality and the association between SEP and mortality among people with mental disorders.

Data Sources

MEDLINE, Embase, PsycINFO, and Web of Science were searched from January 1, 1980, through April 3, 2023, and a snowball search of reference and citation lists was conducted.

Study Selection

Inclusion criteria were observational studies estimating the associations between different types of mental disorders and mortality, stratified by SEP and between SEP and mortality in people with mental disorders.

Data Extraction and Synthesis

Pairs of reviewers independently extracted data using a predefined data extraction form and assessed the risk of bias using the adapted Newcastle-Ottawa scale. Graphical analyses of the dose-response associations and random-effects meta-analyses were performed. Heterogeneity was explored through meta-regressions and sensitivity analyses.

Main Outcomes and Measures

All-cause and cause-specific mortality.

Results

Of 28 274 articles screened, 71 including more than 4 million people with mental disorders met the inclusion criteria (most of which were conducted in high-income countries). The relative associations between mental disorders and mortality were similar across SEP levels. Among people with mental disorders, belonging to the highest rather than the lowest SEP group was associated with lower all-cause mortality (pooled relative risk [RR], 0.79; 95% CI, 0.73-0.86) and mortality from natural causes (RR, 0.73; 95% CI, 0.62-0.85) and higher mortality from external causes (RR, 1.18; 95% CI, 0.99-1.41). Heterogeneity was high (I2 = 83% to 99%). Results from subgroup, sensitivity, and meta-regression analyses were consistent with those from the main analyses. Evidence on absolute scales, specific diagnoses, and specific causes of death was scarce.

Conclusion and Relevance

This study did not find a sufficient body of evidence that SEP moderated the relative association between mental disorders and mortality, but the underlying mortality rates may differ by SEP group, despite having scarcely been reported. This information gap, together with our findings related to SEP and a possible differential risk between natural and external causes of death in individuals with specific types of mental disorders, warrants further research.

Substance Use Treatment Utilization Among Individuals With Substance Use Disorders in the United States During the COVID-19 Pandemic: Findings on the Role of Polysubstance Use, Criminal Justice Involvement, and Mental Illness From the National Survey on Drug Use and Health

This study used the National Survey on Drug Use and Health to assess a nationally representative sample (N = 4596) weighted to represent 35.2 million adults with DSM-5 criteria-determined substance use disorders (SUDs). This study explored substance use treatment utilization in 2020, emphasizing populations with high vulnerability (e.g., criminal justice involvement (CJI) through parole or probation, polysubstance use, severe mental illness, and HIV/STI). Substance use treatment was broadly defined (any inpatient, outpatient/doctor's office, self-help/other for alcohol/drugs). Our results indicated that among adults with SUDs in 2020, 7 million (20%) had multiple SUDs, 1.75 million (5%) had CJI, 5.3 million (15%) had a severe mental illness, and 1.8 million (5%) had a diagnosis of HIV/STI in the last year. Only 7% of individuals with SUD sought any substance use treatment in the past year. CJI (aOR: 13.39, 95% CI: [7.82, 22.94]), serious mental illness (aOR: 3.27, 95% CI: [1.93, 5.55]), and having both 2 (aOR: 2.10, 95% CI: [1.29, 3.42]) or 3 or more SUDs (aOR: 3.46, 95% CI: [1.82, 6.58]) were all associated with a greater likelihood of receiving treatment. Marriage (aOR: 0.43, 95% CI: [0.25, 0.74]) and having an income twice the poverty threshold (aOR: 0.53, 95% CI: [0.29, 0.94]) were associated with reduced odds of receiving any substance use treatment. Compared to those 18 to 25, older individuals had increased odds (2-4 times) of receiving treatment. Interventions are crucially needed to increase access to treatment among those with SUDs.

Effects of leisure activities and general health on the survival of older people: a cohort study in China

Objective

This study aimed to examine the influence of physical and cognitive leisure activities on the survival of older adults in China, while also exploring the potential mediating and moderating effects of general health.

Methods

This study utilized the China Longitudinal Healthy Longevity Survey (CLHLS) datasets spanning from 2008 to 2018, and 10,347 eligible participants were included. The primary study outcome was all-cause mortality, and independent variables included physical leisure activities (PLA), cognitive leisure activities (CLA), and self-rated general health. Three sets of covariates were adjusted, including socio-demographic characteristics, health behaviors, and health status.

Results

The longest survival time was the older people participating in PLA & CLA (mean = 50.31 months), while those participating in neither exhibited the lowest (mean = 29.60 months). Significant differences in survival status were observed in different types of leisure activities participation (Log-rank test, Chi-square = 576.80, p < 0.001). Cox regression indicated that PLA (HR = 0.705, 95% CI: 0.651-0.764), CLA (HR = 0.872, 95% CI: 0.816-0.933), and the both PLA & CLA (HR = 0.700, 95% CI: 0.656-0.747) were protective factors for the survival. Additionally, general health significantly moderated the relationship between PLA and reduced mortality risk (Coefficient = -0.089, p = 0.042). While CLA indirectly influenced the survival through general health (Coefficient = -0.023, p < 0.001). For the older people participating in PLA and CLA, general health played mediating (Coefficient = -0.031, p < 0.001) and moderating (Coefficient = -0.026, p = 0.013) role in the relationship between leisure activities and survival.

Conclusion

Leisure activities and self-rated general health were important predictors of survival of the older adults, and general health exhibited a mediator and moderator in the relationship between leisure activities and survival status.

Health Literacy, Social Networks, and Health Outcomes among Mental Health Clubhouse Members in Hawai'i

Health literacy is the ability to obtain and utilize health information to make health-related decisions and to navigate health systems. Although health literacy has traditionally been understood as an individual-level construct, current research is revealing the impact that social networks can have on health literacy. To date, no studies have examined associations between health literacy and social networks among people with serious mental illness (PWSMI), who are at high risk of physical illness and premature mortality. To begin to fill this gap, this study explores associations between health literacy, relationships with health discussion partners, and self-reported health outcomes in a racially diverse sample of Clubhouse members in Hawai'i. Clubhouses are community mental health centers that promote recovery from mental illness through destigmatization, meaningful activity, and strong social relationships. Health literacy was assessed using two single-item screeners (SILS). In a sample of 163 members, 56.2% reported adequate ability to understand health-related instructions or pamphlets, and 43.3% reported adequate confidence filling out medical forms independently. This is consistent with other health literacy studies with PWSMI in the United States, and indicates lower health literacy within this group than is reported in national averages. Multivariate logistic regression revealed a larger Clubhouse staff social network and completing high school were significantly associated with requiring less help to read materials. Higher age, male gender, and being Native Hawaiian and/or Pacific Islander were associated with less confidence filling out medical forms, while higher self-efficacy was associated with higher confidence filling out medical forms. This study provides preliminary evidence that relationships fostered within Clubhouses are associated with health literacy among PWSMI, and highlights the need for more research to examine how social networks and health literacy interventions can be leveraged in community mental health settings to improve health outcomes within this vulnerable population.

Using a statistical learning approach to identify sociodemographic and clinical predictors of response to clozapine

BACKGROUND

A proportion of people with treatment-resistant schizophrenia fail to show improvement on clozapine treatment. Knowledge of the sociodemographic and clinical factors predicting clozapine response may be useful in developing personalised approaches to treatment.

METHODS

This retrospective cohort study used data from the electronic health records of the South London and Maudsley (SLaM) hospital between 2007 and 2011. Using the Least Absolute Shrinkage and Selection Operator (LASSO) regression statistical learning approach, we examined 35 sociodemographic and clinical factors' predictive ability of response to clozapine at 3 months of treatment. Response was assessed by the level of change in the severity of the symptoms using the Clinical Global Impression (CGI) scale.

RESULTS

We identified 242 service-users with a treatment-resistant psychotic disorder who had their first trial of clozapine and continued the treatment for at least 3 months. The LASSO regression identified three predictors of response to clozapine: higher severity of illness at baseline, female gender and having a comorbid mood disorder. These factors are estimated to explain 18% of the variance in clozapine response. The model's optimism-corrected calibration slope was 1.37, suggesting that the model will underfit when applied to new data.

CONCLUSIONS

These findings suggest that women, people with a comorbid mood disorder and those who are most ill at baseline respond better to clozapine. However, the accuracy of the internally validated and recalibrated model was low. Therefore, future research should indicate whether a prediction model developed by including routinely collected data, in combination with biological information, presents adequate predictive ability to be applied in clinical settings.

Long-Term Safety and Efficacy of Deutetrabenazine in Younger and Older Patients With Tardive Dyskinesia

OBJECTIVES

To assess long-term safety and efficacy of deutetrabenazine in younger (<55 years) and older (≥55 years) adult participants with tardive dyskinesia (TD).

DESIGN

Three-year, single-arm, open-label extension (OLE) study enrolling participants who completed the 12-week, pivotal ARM-TD or AIM-TD studies.

SETTING

Seventy-six centers in the United States and Europe.

PARTICIPANTS

A total of 337 participants with TD (119 younger and 218 older).

INTERVENTION

Deutetrabenazine was initiated at 12 mg/day and titrated once weekly by 6 mg/day using a response-driven dosing regimen until adequate dyskinesia control was reached or a clinically significant adverse event occurred.

MEASUREMENTS

This post hoc analysis assessed change and percent change from baseline in total motor Abnormal Involuntary Movement Scale (AIMS) score, response rates for ≥50% AIMS improvement, Clinical Global Impression of Change (CGIC), Patient Global Impression of Change (PGIC), and safety in younger and older participants with TD.

RESULTS

After 3 years of open-label treatment, mean deutetrabenazine dose was ∼39.5 mg/day in both groups. Mean±SE changes from baseline in total motor AIMS score were -6.7 ± 0.62 and -6.5 ± 0.47 in younger and older participants, respectively (percent changes: -61.4% ± 4.10% and -54.6% ± 3.01%); 76% of younger and 62% of older participants achieved ≥50% AIMS response. Most younger and older participants achieved treatment success per CGIC (67% and 76%) and PGIC (64% and 63%). Deutetrabenazine was generally well tolerated in both groups.

CONCLUSIONS

Deutetrabenazine treatment was associated with sustained improvements in total motor AIMS score, treatment success, and improved quality of life, and was well tolerated in younger and older adults with TD in this 3-year OLE study.

Recruiting and exploring vulnerabilities among young people at risk, or in the early stages of serious mental illness (borderline personality disorder and first episode psychosis)

INTRODUCTION

Many gaps exist in our understanding of the developmental pathways to severe mental illness (SMI), including borderline personality disorder (BPD) and psychosis. However, those who have experienced adverse childhood experiences (ACEs) are at an increased risk and there is evidence to suggest that one of the earliest markers is emotional dysregulation. An area which has received relatively less research attention is the role neurodevelopmental disorders (NDDs) play. The aim of this feasibility study was therefore to explore the clinical profiles of young people early in the course of SMI, including their profiles of ACEs, emotional regulation difficulties, borderline personality traits and NDDs.

METHODS

A cross-sectional study of young people (aged 15-25) at risk of SMI, currently being seen within NHS mental health services, was conducted. This included those with early symptoms of psychosis and/or BPD as assessed by diagnostic interview. Eligible participants self-completed a battery of sociodemographic, clinical, and psychological measures in the company of a researcher. This included assessments of: symptoms of NDDs; borderline pathology traits; ACEs; and difficulties in emotional regulation. Statistical analyses included Mann-Whitney U tests and multiple regression.

RESULTS

Of the 118 potentially eligible participants who were referred, 48 were ultimately included in the study. Young people early in the course of SMI reported a high prevalence of ACEs and deficits in emotional regulation. In total, 79% met criteria for attention deficit hyperactivity disorder (ADHD) and/or autism spectrum disorder (ASD). Emotional dysregulation was found to significantly mediate the association between both ACEs and the frequency of NDDs and borderline personality traits, however given the small sample size these results are preliminary in nature.

CONCLUSION

Young people early in the course of SMI are at an increased risk of experiencing multiple childhood adversities and our results indicate a high prevalence of NDDs amongst them. Emotional dysregulation emerged as a potentially significant early marker of future clinical severity. We suggest that the clinical implications of our findings include routine screening for NDDs and ACEs and an increased recognition of the significance of emotional dysregulation. However, larger scale longitudinal studies are needed to investigate these preliminary findings further.

A long-term, open-label study of valbenazine for tardive dyskinesia

BACKGROUND

Individuals with tardive dyskinesia (TD) who completed a long-term study (KINECT 3 or KINECT 4) of valbenazine (40 or 80 mg/day, once-daily for up to 48 weeks followed by 4-week washout) were enrolled in a subsequent study (NCT02736955) that was primarily designed to further evaluate the long-term safety of valbenazine.

METHODS

Participants were initiated at 40 mg/day (following prior valbenazine washout). At week 4, dosing was escalated to 80 mg/day based on tolerability and clinical assessment of TD; reduction to 40 mg/day was allowed for tolerability. The study was planned for 72 weeks or until termination due to commercial availability of valbenazine. Assessments included the Clinical Global Impression of Severity-TD (CGIS-TD), Patient Satisfaction Questionnaire (PSQ), and treatment-emergent adverse events (TEAEs).

RESULTS

At study termination, 85.7% (138/161) of participants were still active. Four participants had reached week 60, and none reached week 72. The percentage of participants with a CGIS-TD score ≤2 (normal/not ill or borderline ill) increased from study baseline (14.5% [23/159]) to week 48 (64.3% [36/56]). At baseline, 98.8% (158/160) of participants rated their prior valbenazine experience with a PSQ score ≤2 (very satisfied or somewhat satisfied). At week 48, 98.2% (55/56) remained satisfied. Before week 4 (dose escalation), 9.4% of participants had ≥1 TEAE. After week 4, the TEAE incidence was 49.0%. No TEAE occurred in ≥5% of participants during treatment (before or after week 4).

CONCLUSIONS

Valbenazine was well-tolerated and persistent improvements in TD were found in adults who received once-daily treatment for >1 year.

Vascular surgery receipt and outcomes for people with serious mental illnesses: Retrospective cohort study using a large mental healthcare database in South London

OBJECTIVE

Vascular surgery can be common among people with serious mental illness (SMI) given the high prevalence of cardiovascular disease. However, post-operative outcomes following vascular surgery have received little investigation, particularly in a subpopulation of SMI.

METHODS

We conducted a retrospective observational study using data from the South London and Maudsley NHS Foundation Trust (SLaM) via its Clinical Record Interactive Search (CRIS) platform and linkage with Hospital Episode Statistic (HES). Vascular surgery recipients were identified using OPCS version 4 codes. Length of stay (LOS) was modelled using Incidence Rate Ratios (IRRs), and 30-day emergency hospital readmissions using Odds Ratios (ORs) for people with SMI compared with the general population.

RESULTS

Vascular surgery was received by 152 patients with SMI diagnoses (schizophrenia, schizoaffective disorder, bipolar disorder) and 8821 catchment residents without any mental health conditions. People with active SMI symptoms more likely to be admitted to hospital via emergency route OR: 1.80 (95% CI: 1.06, 3.07) and more likely to stay longer in the hospital for vascular surgery IRR: 1.35 (1.01, 1.80) and more likely to be readmitted to hospital via emergency route within 30 days OR: 1.53 (1.02, 2.67). People with SMI who had major open vascular surgery and peripheral endovascular surgery more likely to have worse post-operative outcomes.

CONCLUSION

Our study highlights the risks faced by people with SMI following vascular surgery. These suggest tailored guidelines and policies are needed, based on the identification of pre-operative risk factors, allowing for focused post-vascular surgery care to minimise adverse outcomes.

Individualized prediction of 2-year risk of relapse as indexed by psychiatric hospitalization following psychosis onset: Model development in two first episode samples

BACKGROUND

Although most patients with psychotic disorders experience relapse, it is not possible to predict whether or when an individual patient is going to relapse. We aimed to develop a multifactorial risk prediction algorithm for predicting risk of relapse in first episode psychosis (FEP).

METHODS

Data from two prospectively collected cohorts of FEP patients (N = 1803) were used to develop three multiple logistic prediction models to predict risk of relapse (defined as hospitalization) within the first 2 years of onset of psychosis. Model 1 (M1_S1) used data obtained from clinical notes (Sample 1) while model 2 (M2_S2) applied the same set of predictors using data obtained from research interviews (Sample 2). The final model (Sample 2: M3_S2) used the same predictors plus additional detailed information on predictors. Model performance was evaluated employing measures of overall accuracy, calibration, discrimination and internal validation.

RESULTS

In both samples, the 2-year probability of psychiatric hospitalization was 37%. Of all the models, discrimination accuracy was lowest when limited information (such as socio-demographic and clinical parameters) was included in the prediction model. Model M3_S2 using additional information (descriptors of pattern of cannabis, nicotine, alcohol and other illicit drug use) obtained from research interview had the best discrimination accuracy (Harrell's C index 0.749).

CONCLUSIONS

The measures that contributed most to predicting hospitalization are readily accessible in routine clinical practice, suggesting that a risk prediction tool based on these models would be clinically practicable following validation in independent samples and permit a personalized approach to relapse prevention in psychosis.

RE-KINECT: A Prospective Study of the Presence and Healthcare Burden of Tardive Dyskinesia in Clinical Practice Settings

PURPOSE/BACKGROUND

RE-KINECT (NCT03062033) was designed to assess the presence and impact of possible tardive dyskinesia (TD) in antipsychotic-treated outpatients.

METHODS/PROCEDURES

The study included adults with 3 or more months of lifetime antipsychotic exposure and 1 or more psychiatric disorder. Based on clinician observation and assessment, patients were assigned to cohort 1 (without involuntary movements or with non-TD involuntary movements) or cohort 2 (with involuntary movements confirmed by clinician as possible TD). Baseline assessments included the following: patient characteristics; location/severity of involuntary movements; and impact of possible TD on health-related quality of life, including the EuroQoL 5-Dimensions 5-Level questionnaire.

FINDINGS/RESULTS

Of 739 eligible patients, 204 (27.6%) had clinician-confirmed possible TD (cohort 2). Compared with cohort 1, patients in cohort 2 were significantly older (P < 0.0001), more likely to have schizophrenia or schizoaffective disorder (P < 0.0001) and longer lifetime exposure to antipsychotics (P < 0.0001), and less likely to be working or studying, based on clinician perception (P = 0.0010). Clinician- and patient-rated severity of possible TD movements was significantly correlated in each of 4 body regions (head/face, neck/trunk, upper extremities, lower extremities), for maximum severity in any region, and for total number of affected regions (P < 0.001 for all correlations). For the patient-rated EuroQoL 5-Dimensions 5-Level, the health state visual analog scale score was significantly lower (worse) in cohort 2 versus cohort 1 (66.8 vs 69.7; P = 0.0002), as was the utility index score (0.71 vs 0.76; P < 0.0175).

IMPLICATIONS/CONCLUSIONS

Results from this real-world population indicate that TD occurs frequently and can significantly reduce quality of life in patients with a psychiatric disorder.

A systematic review of the published literature on interventions to improve personal self-care for people with severe mental health problems

Introduction

People with severe mental health problems often struggle to manage everyday tasks such as personal hygiene, housework, shopping, cooking and budgeting. These functional problems result in self-neglect and are associated with specific cognitive impairments and poor outcomes. Despite their importance, little guidance is available for practitioners in how to address these problems.

Method

We conducted a systematic review of the research literature published since 1990 on the effectiveness of interventions that aim to assist people with severe mental health problems to manage their personal self-care. We searched six major electronic databases and followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidance in the conduct of the review and reporting of results.

Results

Our search identified 2808 papers of which only eight met our inclusion criteria. The included papers comprised six randomised controlled trials and two ‘pre-post’ studies reporting on evaluations of five different interventions. We used narrative synthesis to summarise our findings. The strongest evidence was for cognitive adaptation training, comprising environmental supports provided in the home that address the functional problems arising from specific cognitive impairments.

Conclusion

The paucity of research into interventions to assist personal self-care for people with severe mental health problems is surprising. More research in this area is urgently needed.

Hospital and patient factors influencing the health status among patients with schizophrenia, thirty days after hospital discharge: multi-level analysis

BACKGROUND

The time between discharge from hospital and transition to community and home is a critical period for health status among patients with a mental illness, including patients with schizophrenia. This study aimed to investigate crucial patient factors (patient-level) and hospital factors (hospital-level) affecting health status and see whether patient factor effects on health status vary with hospital factors, 30 days after hospital discharge.

METHODS

This is a prospective study of 1255 patients with schizophrenia and their primary caregivers from 13 public mental hospitals across Thailand. Logistic regression and multi-level logistic regression was used to investigate the effects of patient and hospital factors simultaneously on health status, 30 days after hospital discharge.

RESULTS

The intraclass correlation coefficient indicated that 14% of the change in health status was explained by the differences between hospital. Poor health status was identified in 14.26% of patients, 30 days after hospital discharge. The majority of participant patients were male (69.8%), single (71.87%), and the average age was 38.09 (SD = 9.74). The finding also showed that the patient factors; being female (ORadj .53, 95%CI .31,.92), perceived moderate and high levels of positive aspect of caregiving (ORadj .24, 95%CI .14,.42 and ORadj .05, 95%CI .02,.09), perceived readiness for hospital discharge (ORadj .21, 95%CI .13,.33), partial and full adherence to treatment (ORadj .24, 95%CI .14,.42 and ORadj .31, 95%CI .20,.47) showed a reduced likelihood of developing poor health status except substance use (ORadj 1.55, 95%CI .98, 2.44). Hospital factors; discharge planning process and nurse-patient ratio (ORadj 1.64, 95%CI 1.17, 2.30 and ORadj 1.16, 95%CI 1.09, 1.22) showed an increased likelihood of developing poor health status, 30 days after hospital discharge.

CONCLUSIONS

Findings provide relevant information on how both patient and hospital factors determine health status. These results might lead to better targeting of mental health service policy and enable more precise information gathering and allocation of resources. However, future research should be more focused and continue investigating the pathways through which hospital factors influence health status post-discharge.

Metabolic predictors for mortality among patients treated with long-term clozapine - A longitudinal study

Clozapine is the only antipsychotic compound indicated for refractory-schizophrenia. However, it is associated with emergent metabolic dysregulation and cardiovascular risk which may lead to mortality. In this study we aimed to explore predictors for mortality in a large cohort of schizophrenia patients treated with long-term clozapine, using the electronic medical records of the largest health care provider in Israel. Among 27,929 patients diagnosed with schizophrenia, 1817 were prescribed clozapine during the years 2012-2014. We compared patients who survived (n=1705) and patients who died (n=112) during the 3-year follow-up period. Socio-demographic background, cardiovascular morbidity, medication prescriptions and health-care utilization were compared between groups. Cox proportional hazard models were used to assess the association of variables with survival. Chronic hypertension was found to be the only metabolic factor associated with significant hazard ratio (HR) for mortality (HR: 1.55 95% CI: 1.03-2.34). Moreover, those who died had more prevalent ischemic heart disease (14% vs 3%, p<0.005) as well as more frequent hospitalizations (0.01±0.02 vs 0.11±0.18 average per month, p<0.005), for longer periods (2.22±9.87 vs 20.38±33.76 days per month, p<0.005). Among those who died, less patients received prescriptions of statins for hyperlipidemia (13.7% vs. 52.9% in survivors, p<0.005) and hypoglycemics for diabetes mellitus (16.3% vs. 67.1% in survivors, p<0.005). Inadequate treatment of metabolic syndrome, under chronic clozapine treatment, was found to be an independent predictor for mortality. Adequate rigorous regimen for diagnosis and treatment of metabolic risk factors, especially hyperlipidemia and diabetes mellitus, might lower complications rate and prolong life expectancy among this population.

Reviewing a Decade of Research Into Suicide and Related Behaviour Using the South London and Maudsley NHS Foundation Trust Clinical Record Interactive Search (CRIS) System

Suicide is a serious public health issue worldwide, yet current clinical methods for assessing a person's risk of taking their own life remain unreliable and new methods for assessing suicide risk are being explored. The widespread adoption of electronic health records (EHRs) has opened up new possibilities for epidemiological studies of suicide and related behaviour amongst those receiving healthcare. These types of records capture valuable information entered by healthcare practitioners at the point of care. However, much recent work has relied heavily on the structured data of EHRs, whilst much of the important information about a patient's care pathway is recorded in the unstructured text of clinical notes. Accessing and structuring text data for use in clinical research, and particularly for suicide and self-harm research, is a significant challenge that is increasingly being addressed using methods from the fields of natural language processing (NLP) and machine learning (ML). In this review, we provide an overview of the range of suicide-related studies that have been carried out using the Clinical Records Interactive Search (CRIS): a database for epidemiological and clinical research that contains de-identified EHRs from the South London and Maudsley NHS Foundation Trust. We highlight the variety of clinical research questions, cohorts and techniques that have been explored for suicide and related behaviour research using CRIS, including the development of NLP and ML approaches. We demonstrate how EHR data provides comprehensive material to study prevalence of suicide and self-harm in clinical populations. Structured data alone is insufficient and NLP methods are needed to more accurately identify relevant information from EHR data. We also show how the text in clinical notes provide signals for ML approaches to suicide risk assessment. We envision increased progress in the decades to come, particularly in externally validating findings across multiple sites and countries, both in terms of clinical evidence and in terms of NLP and machine learning method transferability.

Rates, types and associations of sexual risk behaviours and sexually transmitted infections in those with severe mental illness: a scoping review

The aim of this scoping review was to: (i) determine rates and types of sexual risk behaviours and sexually-transmitted infections (STIs) in those with severe mental illness (SMI); and (ii) delineate correlates of poor sexual health outcome. The online databases OVID MedLine and PsycINFO were searched from databases inception to February 2018 for any literature with a focus on sexual risk behaviours (inconsistent condom use, multiple sexual partners, substance use and transactional sexual acts) or STIs in SMI populations. Fourteen studies were identified; the quality of these studies ranged from poor to moderate. Outcome definitions were heterogeneous, precluding meta-analysis. We found rates of sexual risk behaviours and STIs to be more common among those with SMI than the rates in the general Australian population. Current studies do not acknowledge the relationship of sexual risk behaviours and STI risk and hence do not provide a full model of sexual health outcomes in those with SMI. In order to improve sexual health outcomes in SMI populations, further research is required of greater methodological rigor, with consensus in the definition of sexual risk behaviours, clarifying causal relationships and where in the course of SMI that these outcomes emerge.

The effects of valbenazine on tardive dyskinesia in older and younger patients

OBJECTIVE

To evaluate the effects of once-daily valbenazine (40 or 80 mg/d) in older and younger adults with tardive dyskinesia (TD).

METHODS

Data were pooled from three 6-week, randomized, double-blind, placebo-controlled (DBPC) studies (KINECT [NCT01688037], KINECT 2 [NCT01733121], and KINECT 3 [NCT02274558]) and two long-term studies (KINECT 3 extension and KINECT 4 [NCT02405091]). Outcomes analyzed in older and younger participants (55 years or older and younger than 55 years, respectively) included Abnormal Involuntary Movement Scale (AIMS) response (threshold of greater than or equal to 50% improvement from baseline in total score [items 1 to 7]) and Clinical Global Impression of Change-Tardive Dyskinesia (CGI-TD) response (score 2 or less ["very much improved" or "much improved"]). Safety assessments included treatment-emergent adverse events (TEAEs).

RESULTS

At week 6 (end of DBPC treatment), the percentage of participants who met the AIMS response threshold was higher with valbenazine versus placebo in both subgroups: 55 years or older (80 mg/d, 39.7% [P < .001]; 40 mg/d, 28.6% [P < .01]; placebo, 9.7%); younger than 55 years (80 mg/d, 39.5% [P < .001]; 40 mg/d, 20.0% [P > .05]; placebo, 10.8%). The percentage of participants with CGI-TD response was also higher with valbenazine versus placebo: 55 years or older (80 mg/d, 41.3% [P < .01]; 40 mg/d, 30.2% [P > .05]; placebo, 19.4%); younger than 55 years (80 mg/d, 39.5% [P < .05]; 40 mg/d, 35.3% [P < .05]; placebo, 18.5%). Responses at week 48 (end of long-term treatment, combined doses) were as follows: 55 years or older (AIMS, 70.7%; CGI-TD, 82.8%); younger than 55 years (AIMS, 58.7%; CGI-TD, 72.3%). No significant differences between older and younger subgroups were found for AIMS or CGI-TD response. No new safety signals or TEAEs of clinical concern were found in older participants who received long-term treatment.

CONCLUSIONS

Valbenazine improved TD and was generally well tolerated in older and younger adults.

Measuring outcomes on a Medical Psychiatric Unit: HoNOS,, CANSAS and costs

OBJECTIVE

To study the course of the functional status and healthcare needs of patients on a Medical Psychiatric Unit (MPU).

METHODS

In a single-centre observational prospective design the Health of the Nation Outcome Scales (HoNOS) and Camberwell Assessment of Needs Short Appraisal Schedule (CANSAS) instruments were administered at admission and discharge. Functional status and healthcare needs were assessed utilizing the HoNOS and CANSAS respectively. The total costs of healthcare claims related to the admission were calculated based on claims data.

RESULTS

In total 50 patients were included with a mean improvement of 4.6 on the HoNOS and an effect size of 0.6.The total number of unmet needs fell from 208 to 115. The median costs per decreased HoNOS point were €2.842 and €6.880 per unmet need.

DISCUSSION

Many patients improved, but due to a large standard deviation at baseline and a low Cronbach's alpha, only 4 patients showed a reliable improvement on functional status. That substantial remission was achieved was shown by the decrease in unmet needs of 93 (44.7%) for the whole group. These observations support the implementation of MPUs, although more research is warranted to ensure cost-effectiveness.

Mortality in schizophrenia: A study of verbal autopsy from cohorts of two rural communities of South India

BACKGROUND

Schizophrenia is a life-shortening disease. Although the rate of mortality of persons with schizophrenia in India is established to be more compared to that in the general population, there is a little exploration of the causes for the same.

AIM

The aim of this study is to explore the causes of death in two rural cohorts of schizophrenia.

MATERIALS AND METHODS

In-person interviews of primary caregivers of 53 deceased persons with schizophrenia were conducted using the World Health Organization's verbal autopsy 2014 instrument. Physician-based method was used to determine the causes of death.

RESULTS

Average age of 53 deceased schizophrenia patients was 50.45 ± 13.65 years with almost equal gender ratio. Just more than two-thirds of patients were married, just more than one-third are educated up to primary school and also had no formal education each. Noncommunicable diseases (NCDs) were the most common causes of death (30, 56.6%) in this sample, followed by communicable disease (7, 13.2%), and then unnatural deaths (suicide - 8, 15%, and road traffic accidents - 3, 5.6%).

CONCLUSIONS

It is the first study in India to explore the causes of death in schizophrenia. NCDs being the most common cause of death in schizophrenia suggests to the need of integration of schizophrenia care into general health care.

Public Awareness, Beliefs, And Attitudes Toward Bipolar Disorder In Saudi Arabia

OBJECTIVES

To examine public's knowledge, beliefs, and attitudes toward bipolar disorder (BP) in Saudi Arabia (SA).

METHODS

A cross-sectional survey was performed in 2016 in Riyadh, SA. The survey included sociodemographic characteristics and BP awareness scale.

RESULTS

Of 416 participants, 49.5% had prior knowledge of BP, mainly from internet and social media, and 57% considered it to be common in SA. About half believed BP is caused by a neurophysiological or neurochemical imbalance and that it can be treated with psychiatric medications. Supernatural causes, weak faith, and weakness of character were considered causes of BP by 55%, 48%, and 40% of participants, respectively. Recreational activities and head bandaging by traditional therapists were considered viable treatment options by 55% and 41% of participants, respectively. Students and healthcare professionals scored significantly higher on awareness scale. Regarding attitude, a majority believed that persons with BP can work effectively ‎(86%)‎, have to pull themselves together to get over it (47%), and consider it a shame to mention that someone in a family is affected by BP (32%). Regarding relationships, 22% were not willing to maintain a friendship and 39.3% were not willing to marry someone with BP.

CONCLUSIONS

This study revealed suboptimal public awareness towards BP in SA. It identified several misconceptions and negative attitudes toward patients with BP. Further studies are needed to investigate potential public interventions to improve literacy of BP.

Acute general hospital admissions in people with serious mental illness

BACKGROUND

Serious mental illness (SMI, including schizophrenia, schizoaffective disorder, and bipolar disorder) is associated with worse general health. However, admissions to general hospitals have received little investigation. We sought to delineate frequencies of and causes for non-psychiatric hospital admissions in SMI and compare with the general population in the same area.

METHODS

Records of 18 380 individuals with SMI aged ⩾20 years in southeast London were linked to hospitalisation data. Age- and gender-standardised admission ratios (SARs) were calculated by primary discharge diagnoses in the 10th edition of the World Health Organization International Classification of Diseases (ICD-10) codes, referencing geographic catchment data.

RESULTS

Commonest discharge diagnosis categories in the SMI cohort were urinary conditions, digestive conditions, unclassified symptoms, neoplasms, and respiratory conditions. SARs were raised for most major categories, except neoplasms for a significantly lower risk. Hospitalisation risks were specifically higher for poisoning and external causes, injury, endocrine/metabolic conditions, haematological, neurological, dermatological, infectious and non-specific ('Z-code') causes. The five commonest specific ICD-10 diagnoses at discharge were 'chronic renal failure' (N18), a non-specific code (Z04), 'dental caries' (K02), 'other disorders of the urinary system' (N39), and 'pain in throat and chest' (R07), all of which were higher than expected (SARs ranging 1.57-6.66).

CONCLUSION

A range of reasons for non-psychiatric hospitalisation in SMI is apparent, with self-harm, self-neglect and/or reduced healthcare access, and medically unexplained symptoms as potential underlying explanations.

Dependent functional status is associated with unplanned postoperative intubation after elective cervical spine surgery: a national registry analysis

PURPOSE

The impact of preoperative functional status on 30-day unplanned postoperative intubation and clinical outcomes among patients who underwent cervical spine surgery is not well-described. We hypothesized that functional dependence is associated with 30-day unplanned postoperative intubation and that among the reintubated cohort, functional dependence is associated with adverse postoperative clinical outcomes after cervical spine surgery.

METHODS

Utilizing the 2007-2016 American College of Surgeons National Surgical Quality Improvement Program database, we identified adult elective anterior and posterior cervical spine surgery patients by Current Procedural Terminology codes. We performed (1) a Cox Proportional Hazard analysis for the following outcomes: reintubation, prolonged ventilator use, and pneumonia and (2) an adjusted logistic regression analysis among patients that required postoperative reintubation to evaluate the association of functional status with adverse postoperative outcomes.

RESULTS

The sample size was 26,263, of which 550 (2.1%) were functionally dependent. The adjusted model suggested that when compared with functionally independent patients, dependent patients were at increased risk of unplanned 30-day intubation (HR 2.05, 95% CI 1.26-3.34; P = 0.003). The adjusted risk of 30-day postoperative pneumonia was significantly higher in patients with functional dependence (HR 1.61, 95% CI 1.02-2.54, P = 0.036). Among patients that required postoperative reintubation, the odds of 30-day mortality was significantly higher in patients with functional dependence (OR 5.82, 95% CI 1.59-23.4, P < 0.001).

CONCLUSION

Preoperative functional dependence is a good marker for estimating postoperative unplanned intubation following cervical spine surgery.

Effects of Aerobic Exercise on Metabolic Syndrome, Cardiorespiratory Fitness, and Symptoms in Schizophrenia Include Decreased Mortality

Schizophrenia is a severe psychiatric disorder with a lifetime prevalence of about 1%. People with schizophrenia have a 4-fold higher prevalence of metabolic syndrome than the general population, mainly because of antipsychotic treatment but perhaps also because of decreased physical activity. Metabolic syndrome is a risk factor for cardiovascular diseases, and the risk of these diseases is 2- to 3-fold higher in schizophrenia patients than in the general population. The suicide risk is also higher in schizophrenia, partly as a result of depression, positive, and cognitive symptoms of the disease. The higher suicide rate and higher rate of cardiac mortality, a consequence of the increased prevalance of cardiovascular diseases, contribute to the reduced life expectancy, which is up to 20 years lower than in the general population. Regular physical activity, especially in combination with psychosocial and dietary interventions, can improve parameters of the metabolic syndrome and cardiorespiratory fitness. Furthermore, aerobic exercise has been shown to improve cognitive deficits; total symptom severity, including positive and negative symptoms; depression; quality of life; and global functioning. High-intensity interval endurance training is a feasible and effective way to improve cardiorespiratory fitness and metabolic parameters and has been established as such in somatic disorders. It may have more beneficial effects on the metabolic state than more moderate and continuous endurance training methods, but to date it has not been investigated in schizophrenia patients in controlled, randomized trials. This review discusses physical training methods to improve cardiorespiratory fitness and reduce metabolic syndrome risk factors and symptoms in schizophrenia patients. The results of studies and future high-quality clinical trials are expected to lead to the development of an evidence-based physical training program for patients that includes practical recommendations, such as the optimal length and type of aerobic exercise programs and the ideal combination of exercise, psychoeducation, and individual weight management sessions.

Early Intervention in Psychosis: Health of the Nation Outcome Scales (HoNOS) Outcomes From a Five-Year Prospective Study

INTRODUCTION

Over the last two decades, mental health services internationally have shifted towards intervening early in psychosis. The critical period for intervention is estimated to be five-years and many specialised programs target early psychosis.

AIM/QUESTION

This prospective cohort study aimed to evaluate five-year outcomes from an early psychosis program (EPP) that adopted an integrated model, providing nursing and multidisciplinary community mental healthcare to clients aged 16-65years, beyond the typical age range of 16-25years.

METHOD

We examined one routine outcome measure, the Health of the Nation Outcome Scales (HoNOS) across episodes of care for clients receiving EPP over a 5year period (n=239), comparing these results with HoNOS outcomes in an Australian national dataset for all public mental health clients.

RESULTS

HoNOS improvements were highly significant from intake to discharge and from review to discharge for EPP clients, and these compared well with national outcome performance.

CONCLUSION

There is potential for mental health nurses and other clinicians to significantly improve client symptoms and functioning, in a model of early psychosis treatment beyond a youth focus.

Clozapine and incidence of myocarditis and sudden death - Long term Australian experience

BACKGROUND

Clozapine is the cornerstone of therapy for refractory schizophrenia; however, the potential for cardiotoxicity is an important limitation in its use. In the current analysis we sought to evaluate the long term cardiac outcomes of clozapine therapy.

METHODS

All-cause mortality, incidence of sudden death and time to myocarditis were assessed in a cohort of patients maintained on clozapine between January 2009 and December 2015. All patients had regular electrocardiograms, complete blood count, clozapine levels and echocardiography as part of a formal protocol.

RESULTS

A total of 503 patients with treatment-resistant schizophrenia were maintained on clozapine during the study period of which 93 patients (18%) discontinued therapy with 29 (6%) deaths. The incidence of sudden death and myocarditis were 2% (n=10) and 3% (n=14) respectively. Amongst patients with sudden death, 7 out of 10 (70%) were documented to have used illicit drugs prior to death, with a tendency to weight gain also noted. The mean time to myocarditis post clozapine commencement was 15±7days. The reduction in left ventricular ejection fraction in those with myocarditis was 11±2%.

CONCLUSION

Myocarditis and sudden cardiac death are uncommon but clinically important complications in a cohort of patients followed while maintained on clozapine undergoing regular cardiac assessment. Further studies are required to document the role of preventive measures for left ventricular dysfunction and sudden cardiac death in this population.

Effect of patient age on treatment response in a study of the acute exacerbation of psychosis in schizophrenia

Younger patients with schizophrenia have most likely experienced fewer adverse consequences of the illness than older patients who may have experienced a lifetime of treatment as well as socio-economic problems as a consequence of the illness. There is limited information regarding differential efficacy of long-acting injectable (LAI) antipsychotic medications across the age span in patients with schizophrenia. We conducted a post hoc age and gender analysis of treatment response to aripiprazole lauroxil (AL; ARISTADA®; Alkermes, Inc.), in a 12-week, double-blind, placebo-controlled, multinational, Phase 3 study evaluating two doses of AL (441mg and 882mg) versus placebo in adult patients experiencing an acute exacerbation of schizophrenia within the previous 2months. We examined change in the total Positive and Negative Syndrome Scale (PANSS) scores from baseline using analysis of covariance and categorical treatment response (defined as ≥30% total PANSS score improvement from baseline) in the following age groups: <30, 30-39, 40-49, and 50-69years old. Age and gender did not moderate the treatment response in this study. Both AL 441mg and AL 882mg showed an early and significant improvement of the mean total PANSS scores and categorical treatment responses compared to placebo in all four age groups, including younger patients regardless of gender that was sustained over the 85-day treatment period.

Novel psychoactive substances: An investigation of temporal trends in social media and electronic health records

BACKGROUND

Public health monitoring is commonly undertaken in social media but has never been combined with data analysis from electronic health records. This study aimed to investigate the relationship between the emergence of novel psychoactive substances (NPS) in social media and their appearance in a large mental health database.

METHODS

Insufficient numbers of mentions of other NPS in case records meant that the study focused on mephedrone. Data were extracted on the number of mephedrone (i) references in the clinical record at the South London and Maudsley NHS Trust, London, UK, (ii) mentions in Twitter, (iii) related searches in Google and (iv) visits in Wikipedia. The characteristics of current mephedrone users in the clinical record were also established.

RESULTS

Increased activity related to mephedrone searches in Google and visits in Wikipedia preceded a peak in mephedrone-related references in the clinical record followed by a spike in the other 3 data sources in early 2010, when mephedrone was assigned a 'class B' status. Features of current mephedrone users widely matched those from community studies.

CONCLUSIONS

Combined analysis of information from social media and data from mental health records may assist public health and clinical surveillance for certain substance-related events of interest. There exists potential for early warning systems for health-care practitioners.

Mental distress and functional health in the United States

INTRODUCTION

Mental illness prevalence is increasing in USA. Understanding the relationship between functional status and mental health is crucial in optimizing psychiatric treatment.

METHODS

We used 2000-2014 BRFSS data to examine the relationship between functional health and frequent mental distress in 51 states.

RESULTS

East-South-Central US (14.88%) had the highest prevalence of frequent mental distress and West-North-Central (9.42%) the lowest. Tennessee (15.7%) had the highest prevalence of frequent mental distress and North Dakota (7.4%) the lowest. East-South-Central had the highest prevalence on all functional limitation items. West Virginia had the highest prevalence of functional limitation (29.1%), use of special equipment (14.0%), blindness (8.6%), walking difficulty (23.0%), and difficulty running errands (12%). Females were more likely to report frequent mental distress in all states and more likely to report functional limitations in 32 states. Those who were divorced, smoker, unemployed, and of African American/American Indian/Alaskan native/other race were more likely to have a functional limitation. The prevalence of frequent mental distress increased steadily from 2000 for males and females but showed a decline from 2013 to 2014. The rate of increase was higher between 2008 and 2013 compared to previous years.

CONCLUSIONS

Our study showed a high prevalence of mental distress and poor functional health in the US with a large variation between states and socio-demographic groups. Moreover, our findings showed a strong association between poor mental health and functional limitations. Our findings call for integrating mental and physical health research and clinical care to reduce the burden of mental health in the US.

Serious Mental Illness and Risk for Hospitalizations and Rehospitalizations for Ambulatory Care-sensitive Conditions in Denmark: A Nationwide Population-based Cohort Study

BACKGROUND

Hospitalizations for ambulatory care-sensitive conditions (ACSCs) and early rehospitalizations increase health care costs.

OBJECTIVES

To determine if individuals with serious mental illnesses (SMIs) (eg, schizophrenia or bipolar disorder) are at increased risk for hospitalizations for ACSCs, and rehospitalization for the same or another ACSC, within 30 days.

RESEARCH DESIGN

Population-based cohort study.

PARTICIPANTS

A total of 5.9 million Danish persons aged 18 years and older between January 1, 1999 and December 31, 2013.

MEASURES

The Danish Psychiatric Central Register provided information on SMI diagnoses and the Danish National Patient Register on hospitalizations for ACSCs and 30-day rehospitalizations.

RESULTS

SMI was associated with increased risk for having any ACSC-related hospitalization after adjusting for demographics, socioeconomic factors, comorbidities, and prior primary care utilization [incidence rate ratio (IRR): 1.41; 95% confidence interval (95% CI), 1.37-1.45]. Among individual ACSCs, SMI was associated with increased risk for hospitalizations for angina (IRR: 1.14, 95% CI, 1.04-1.25), chronic obstructive pulmonary disease/asthma exacerbation (IRR: 1.87; 95% CI, 1.74-2.00), congestive heart failure exacerbation (IRR: 1.25; 95% CI, 1.16-1.35), and diabetes (IRR: 1.43; 95% CI, 1.31-1.57), appendiceal perforation (IRR: 1.49; 95% CI, 1.30-1.71), pneumonia (IRR: 1.72; 95% CI, 1.66-1.79), and urinary tract infection (IRR: 1.70; 95% CI, 1.62-1.78). SMI was also associated with increased risk for rehospitalization within 30 days for the same (IRR: 1.28; 95% CI, 1.18-1.40) or for another ACSC (IRR: 1.62; 95% CI, 1.49-1.76).

CONCLUSION

Persons with SMI are at increased risk for hospitalizations for ACSCs, and after discharge, are at increased risk for rehospitalizations for ACSCs within 30 days.

Association of cannabis use with hospital admission and antipsychotic treatment failure in first episode psychosis: an observational study

OBJECTIVE

To investigate whether cannabis use is associated with increased risk of relapse, as indexed by number of hospital admissions, and whether antipsychotic treatment failure, as indexed by number of unique antipsychotics prescribed, may mediate this effect in a large data set of patients with first episode psychosis (FEP).

DESIGN

Observational study with exploratory mediation analysis.

SETTING

Anonymised electronic mental health record data from the South London and Maudsley NHS Foundation Trust.

PARTICIPANTS

2026 people presenting to early intervention services with FEP.

EXPOSURE

Cannabis use at presentation, identified using natural language processing.

MAIN OUTCOME MEASURES

admission to psychiatric hospital and clozapine prescription up to 5 years following presentation.

MEDIATOR

Number of unique antipsychotics prescribed.

RESULTS

Cannabis use was present in 46.3% of the sample at first presentation and was particularly common in patients who were 16-25, male and single. It was associated with increased frequency of hospital admission (incidence rate ratio 1.50, 95% CI 1.25 to 1.80), increased likelihood of compulsory admission (OR 1.55, 1.16 to 2.08) and greater number of days spent in hospital (β coefficient 35.1 days, 12.1 to 58.1). The number of unique antipsychotics prescribed, mediated increased frequency of hospital admission (natural indirect effect 1.09, 95% CI 1.01 to 1.18; total effect 1.50, 1.21 to 1.87), increased likelihood of compulsory admission (natural indirect effect (NIE) 1.27, 1.03 to 1.58; total effect (TE) 1.76, 0.81 to 3.84) and greater number of days spent in hospital (NIE 17.9, 2.4 to 33.4; TE 34.8, 11.6 to 58.1).

CONCLUSIONS

Cannabis use in patients with FEP was associated with an increased likelihood of hospital admission. This was linked to the prescription of several different antipsychotic drugs, indicating clinical judgement of antipsychotic treatment failure. Together, this suggests that cannabis use might be associated with worse clinical outcomes in psychosis by contributing towards failure of antipsychotic treatment.

Cohort profile of the South London and Maudsley NHS Foundation Trust Biomedical Research Centre (SLaM BRC) Case Register: current status and recent enhancement of an Electronic Mental Health Record-derived data resource

PURPOSE

The South London and Maudsley National Health Service (NHS) Foundation Trust Biomedical Research Centre (SLaM BRC) Case Register and its Clinical Record Interactive Search (CRIS) application were developed in 2008, generating a research repository of real-time, anonymised, structured and open-text data derived from the electronic health record system used by SLaM, a large mental healthcare provider in southeast London. In this paper, we update this register's descriptive data, and describe the substantial expansion and extension of the data resource since its original development.

PARTICIPANTS

Descriptive data were generated from the SLaM BRC Case Register on 31 December 2014. Currently, there are over 250,000 patient records accessed through CRIS.

FINDINGS TO DATE

Since 2008, the most significant developments in the SLaM BRC Case Register have been the introduction of natural language processing to extract structured data from open-text fields, linkages to external sources of data, and the addition of a parallel relational database (Structured Query Language) output. Natural language processing applications to date have brought in new and hitherto inaccessible data on cognitive function, education, social care receipt, smoking, diagnostic statements and pharmacotherapy. In addition, through external data linkages, large volumes of supplementary information have been accessed on mortality, hospital attendances and cancer registrations.

FUTURE PLANS

Coupled with robust data security and governance structures, electronic health records provide potentially transformative information on mental disorders and outcomes in routine clinical care. The SLaM BRC Case Register continues to grow as a database, with approximately 20,000 new cases added each year, in addition to extension of follow-up for existing cases. Data linkages and natural language processing present important opportunities to enhance this type of research resource further, achieving both volume and depth of data. However, research projects still need to be carefully tailored, so that they take into account the nature and quality of the source information.

Do antidepressants increase the risk of mania and bipolar disorder in people with depression? A retrospective electronic case register cohort study

OBJECTIVES

To investigate the association between antidepressant therapy and the later onset of mania/bipolar disorder.

DESIGN

Retrospective cohort study using an anonymised electronic health record case register.

SETTING

South London and Maudsley National Health Service (NHS) Trust (SLaM), a large provider of inpatient and community mental healthcare in the UK.

PARTICIPANTS

21,012 adults presenting to SLaM between 1 April 2006 and 31 March 2013 with unipolar depression.

EXPOSURE

Prior antidepressant therapy recorded in electronic health records.

MAIN OUTCOME MEASURE

Time to subsequent diagnosis of mania or bipolar disorder from date of diagnosis of unipolar depression, censored at 31 March 2014.

METHODS

Multivariable Cox regression analysis with age and gender as covariates.

RESULTS

The overall incidence rate of mania/bipolar disorder was 10.9 per 1000 person-years. The peak incidence of mania/bipolar disorder incidence was seen in patients aged between 26 and 35 years (12.3 per 1000 person-years). Prior antidepressant treatment was associated with an increased incidence of mania/bipolar disorder ranging from 13.1 to 19.1 per 1000 person-years. Multivariable analysis indicated a significant association with selective serotonin reuptake inhibitors (HR 1.34, 95% CI 1.18 to 1.52) and venlafaxine (1.35, 1.07 to 1.70).

CONCLUSIONS

In people with unipolar depression, antidepressant treatment is associated with an increased risk of subsequent mania/bipolar disorder. These findings highlight the importance of considering risk factors for mania when treating people with depression.

Promoting physical health for people with schizophrenia by reducing disparities in medical and dental care

OBJECTIVE

Acquiring a diagnosis of schizophrenia reduces life expectancy for many reasons including poverty, difficulties in communication, side-effects of medication and access to care. This mortality gap is driven by natural deaths; cardiovascular disease is a major cause, but outcomes for people with severe mental illness are worse for many physical health conditions, including cancer, fractures and complications of surgery. We set out to examine the literature on disparities in medical and dental care experienced by people with schizophrenia and suggest possible approaches to improving health.

METHOD

This narrative review used a targeted literature search to identify the literature on physical health disparities in schizophrenia.

RESULTS

There is evidence of inequitable access to and/or uptake of physical and dental health care by those with schizophrenia.

CONCLUSION

The goal was to reduce the mortality gap through equity of access to all levels of health care, including acute care, long-term condition management, preventative medicine and health promotion. We suggest solutions to promote health, wellbeing and longevity in this population, prioritising identification of and intervention for risk factors for premature morbidity and mortality. Shared approaches are vital, while joint education of clinicians will help break down the artificial mind-body divide.

Physical Exercise Alleviates Health Defects, Symptoms, and Biomarkers in Schizophrenia Spectrum Disorder

Schizophrenia spectrum disorders are characterized by symptom profiles consisting of positive and negative symptoms, cognitive impairment, and a plethora of genetic, epigenetic, and phenotypic biomarkers. Assorted animal models of these disorders and clinical neurodevelopmental indicators have implicated neurodegeneration as an element in the underlying pathophysiology. Physical exercise or activity regimes--whether aerobic, resistance, or endurance--ameliorate regional brain and functional deficits not only in affected individuals but also in animal models of the disorder. Cognitive deficits, often linked to regional deficits, were alleviated by exercise, as were quality-of-life, independent of disorder staging and risk level. Apoptotic processes intricate to the etiopathogenesis of schizophrenia were likewise attenuated by physical exercise. There is also evidence of manifest benefits endowed by physical exercise in preserving telomere length and integrity. Not least, exercise improves overall health and quality-of-life. The notion of scaffolding as the outcome of physical exercise implies the "buttressing" of regional network circuits, neurocognitive domains, anti-inflammatory defenses, maintenance of telomeric integrity, and neuro-reparative and regenerative processes.

Mood instability is a common feature of mental health disorders and is associated with poor clinical outcomes

OBJECTIVES

Mood instability is a clinically important phenomenon but has received relatively little research attention. The objective of this study was to assess the impact of mood instability on clinical outcomes in a large sample of people receiving secondary mental healthcare.

DESIGN

Observational study using an anonymised electronic health record case register.

SETTING

South London and Maudsley NHS Trust (SLaM), a large provider of inpatient and community mental healthcare in the UK.

PARTICIPANTS

27,704 adults presenting to SLaM between April 2006 and March 2013 with a psychotic, affective or personality disorder.

EXPOSURE

The presence of mood instability within 1 month of presentation, identified using natural language processing (NLP).

MAIN OUTCOME MEASURES

The number of days spent in hospital, frequency of hospital admission, compulsory hospital admission and prescription of antipsychotics or non-antipsychotic mood stabilisers over a 5-year follow-up period.

RESULTS

Mood instability was documented in 12.1% of people presenting to mental healthcare services. It was most frequently documented in people with bipolar disorder (22.6%), but was common in people with personality disorder (17.8%) and schizophrenia (15.5%). It was associated with a greater number of days spent in hospital (β coefficient 18.5, 95% CI 12.1 to 24.8), greater frequency of hospitalisation (incidence rate ratio 1.95, 1.75 to 2.17), greater likelihood of compulsory admission (OR 2.73, 2.34 to 3.19) and an increased likelihood of prescription of antipsychotics (2.03, 1.75 to 2.35) or non-antipsychotic mood stabilisers (2.07, 1.77 to 2.41).

CONCLUSIONS

Mood instability occurs in a wide range of mental disorders and is not limited to affective disorders. It is generally associated with relatively poor clinical outcomes. These findings suggest that clinicians should screen for mood instability across all common mental health disorders. The data also suggest that targeted interventions for mood instability may be useful in patients who do not have a formal affective disorder.

Delays before Diagnosis and Initiation of Treatment in Patients Presenting to Mental Health Services with Bipolar Disorder

Background

Bipolar disorder is a significant cause of morbidity and mortality. Although existing treatments are effective, there is often a substantial delay before diagnosis and treatment initiation. We sought to investigate factors associated with the delay before diagnosis of bipolar disorder and the onset of treatment in secondary mental healthcare.

Method

Retrospective cohort study using anonymised electronic mental health record data from the South London and Maudsley NHS Foundation Trust (SLaM) Biomedical Research Centre (BRC) Case Register on 1364 adults diagnosed with bipolar disorder between 2007 and 2012. The following predictor variables were analysed in a multivariable Cox regression analysis: age, gender, ethnicity, compulsory admission to hospital under the UK Mental Health Act, marital status and other diagnoses prior to bipolar disorder. The outcomes were time to recorded diagnosis from first presentation to specialist mental health services (the diagnostic delay), and time to the start of appropriate therapy (treatment delay).

Results

The median diagnostic delay was 62 days (interquartile range: 17–243) and median treatment delay was 31 days (4–122). Compulsory hospital admission was associated with a significant reduction in both diagnostic delay (hazard ratio 2.58, 95% CI 2.18–3.06) and treatment delay (4.40, 3.63–5.62). Prior diagnoses of other psychiatric disorders were associated with increased diagnostic delay, particularly alcohol (0.48, 0.33–0.41) and substance misuse disorders (0.44, 0.31–0.61). Prior diagnosis of schizophrenia and psychotic depression were associated with reduced treatment delay.

Conclusions

Some individuals experience a significant delay in diagnosis and treatment of bipolar disorder after initiation of specialist mental healthcare, particularly those who have prior diagnoses of alcohol and substance misuse disorders. These findings highlight a need for further study on strategies to better identify underlying symptoms and offer appropriate treatment sooner in order to facilitate improved clinical outcomes, such as developing specialist early intervention services to identify and treat people with bipolar disorder.

The effect of clozapine on premature mortality: an assessment of clinical monitoring and other potential confounders

Clozapine can cause severe adverse effects yet it is associated with reduced mortality risk. We test the hypothesis this association is due to increased clinical monitoring and investigate risk of premature mortality from natural causes. We identified 14 754 individuals (879 deaths) with serious mental illness (SMI) including schizophrenia, schizoaffective and bipolar disorders aged ≥ 15 years in a large specialist mental healthcare case register linked to national mortality tracing. In this cohort study we modeled the effect of clozapine on mortality over a 5-year period (2007-2011) using Cox regression. Individuals prescribed clozapine had more severe psychopathology and poorer functional status. Many of the exposures associated with clozapine use were themselves risk factors for increased mortality. However, we identified a strong association between being prescribed clozapine and lower mortality which persisted after controlling for a broad range of potential confounders including clinical monitoring and markers of disease severity (adjusted hazard ratio 0.4; 95% CI 0.2-0.7; p = .001). This association remained after restricting the sample to those with a diagnosis of schizophrenia or those taking antipsychotics and after using propensity scores to reduce the impact of confounding by indication. Among individuals with SMI, those prescribed clozapine had a reduced risk of mortality due to both natural and unnatural causes. We found no evidence to indicate that lower mortality associated with clozapine in SMI was due to increased clinical monitoring or confounding factors. This is the first study to report an association between clozapine and reduced risk of mortality from natural causes.

The impact of co-morbid personality disorder on use of psychiatric services and involuntary hospitalization in people with severe mental illness

PURPOSE

To examine the impact of co-morbid personality disorder (PD), on inpatient and community-based service use and risk of involuntary hospitalization, amongst patients with severe mental illness (SMI).

METHODS

We identified SMI cases (schizophrenia, schizoaffective and bipolar disorder) with and without co-morbid PD, and PD cases, aged ≥18 years, in a large secondary mental healthcare case register. Using multivariable logistic regression, we examined the association between co-morbid PD and high level of inpatient and community-based service use (defined as the top decile of service use), and involuntary hospitalization, respectively, adjusting for socio-demographics, clinical symptoms and social functioning.

RESULTS

Severe mental illness patients with co-morbid PD (SMI-PD) (n = 961) had more severe symptoms and social functioning problems compared to SMI patients without PD (n = 10,963) and patients who had PD but no concurrent SMI (n = 2,309). A greater proportion of SMI-PD patients were high inpatient service users (22.4 vs. 10.1 %). This association was attenuated but remained significant, after adjustment (fully adjusted odds ratio, OR 2.31, 95 % CI 1.88-2.84). The association between SMI-PD and high community-based service use was confounded by symptoms and social functioning. Compared to patients with SMI, SMI-PD patients were significantly more likely to experience involuntary hospitalization (fully adjusted OR 1.56, 95 % CI 1.31-1.85).

CONCLUSIONS

In SMI patients, co-morbidity with PD is robustly associated with both high use of inpatient psychiatric services and an increased likelihood of involuntary hospitalization. Patients with SMI and co-morbid PD are likely to require tailored interventions that target both the underlying personality pathology as well as the Axis I disorder.

Mini-mental state examination as a predictor of mortality among older people referred to secondary mental healthcare

Background

Lower levels of cognitive function have been found to be associated with higher mortality in older people, particularly in dementia, but the association in people with other mental disorders is still inconclusive.

Methods and Findings

Data were analysed from a large mental health case register serving a geographic catchment of 1.23 million residents, and associations were investigated between cognitive function measured by the Mini-Mental State Examination (MMSE) and survival in patients aged 65 years old and over. Cox regressions were carried out, adjusting for age, gender, psychiatric diagnosis, ethnicity, marital status, and area-level socioeconomic index. A total of 6,704 subjects were involved, including 3,368 of them having a dementia diagnosis and 3,336 of them with depression or other diagnoses. Descriptive outcomes by Kaplan-Meier curves showed significant differences between those with normal and impaired cognitive function (MMSE score<25), regardless of a dementia diagnosis. As a whole, the group with lower cognitive function had an adjusted hazard ratio (HR) of 1.42 (95% CI: 1.28, 1.58) regardless of diagnosis. An HR of 1.23 (95% CI: 1.18, 1.28) per quintile increment of MMSE was also estimated after confounding control. A linear trend of MMSE in quintiles was observed for the subgroups of dementia and other non-dementia diagnoses (both p-values<0.001). However, a threshold effect of MMSE score under 20 was found for the specific diagnosis subgroups of depression.

Conclusion

Current study identified an association between cognitive impairment and increased mortality in older people using secondary mental health services regardless of a dementia diagnosis. Causal pathways between this exposure and outcome (for example, suboptimal healthcare) need further investigation.

Predictors of natural and unnatural mortality among patients with personality disorder: evidence from a large UK case register

BACKGROUND

People with personality disorder have reduced life expectancy, yet, within this population, little is known about the clinical predictors of natural and unnatural deaths. We set out to investigate this, using a large cohort of secondary mental health patients with personality disorder.

METHODS

We identified patients with an ICD-10 diagnosis of personality disorder, aged ≥15 years in a large secondary mental healthcare case register. The case register was linked to national mortality tracing. Using Cox regression, we modelled the effect of a number of pre-specified clinical variables on all-cause, natural cause and unnatural cause mortality.

FINDINGS

2,440 patients were identified. Eighty-five deaths (3.5% of cohort) occurred over a 5-year observation period, of which over 50% were from natural causes. All-cause mortality was associated with alcohol or drug use (adjusted Hazard Ratio [aHR] 2.3; 95% CI 1.3-4.1), physical illness (aHR 1.9; 95% CI 1.0-3.6), and functional impairment (aHR 1.9; 95% CI 1.0-3.6). Natural cause mortality was associated with mild problems of alcohol or drug use (aHR 3.4; 95% CI 1.5-7.4), and physical illness (aHR 2.4; 95% CI 1.0-5.6). Unnatural cause mortality was associated only with severe alcohol or drug use (aHR 3.1; 95% CI 1.3-7.3).

INTERPRETATION

Alcohol and drug use, physical illness, and functional impairment are predictors of mortality in individuals with personality disorder. Clinicians should be aware of the existence of problems in these domains, even at mild levels, when assessing the needs of patients with personality disorder.

Cardiovascular health literacy and treatment adherence in persons with serious mental illness

Persons with serious mental illnesses have shorter life spans than the general population, and their earlier death is often related to cardiovascular disease. This study examined health literacy and cardiovascular medication adherence in a sample of 98 participants with serious mental illness. Sixty-two percent of the participants had adequate health literacy as measured by the Test of Functional Health Literacy in Adults. The association between health literacy and medication adherence was not significant after controlling for education. There was a significant association between health literacy and education level, health literacy and site, and health literacy and the sodium intake subscale of the Hill-Bone adherence scale.
