The physical health of Maori with bipolar disorder.

AIMS: There is very little empirical evidence about the relationship between severe mental illness and the physical health of Indigenous peoples. This paper aims to compare the physical health of Maori and non-Maori with a diagnosis of bipolar disorder in contact with NZ mental health services. METHODS: A cohort of Maori and non-Maori with a current bipolar disorder diagnosis at 1 January 2010 were identified from routine mental health services data and followed up for non-psychiatric hospital admissions and deaths over the subsequent 5 years. RESULTS: Maori with bipolar disorder had a higher level of morbidity and a higher risk of death from natural causes compared to non-Maori with the same diagnosis, indicating higher levels of physical health need. The rate of medical and surgical hospitalisation was not higher among Maori compared to non-Maori (as might be expected given increased health needs) which suggests under-treatment of physical health conditions in this group may be a factor in the observed higher risk of mortality from natural causes for Maori. CONCLUSION: This study provides the first indication that systemic factors which cause health inequities between Maori and non-Maori are compounded for Maori living with severe mental illness. Further exploration of other diagnostic groups and subgroups is needed to understand the best approach to reducing these inequalities.

Potential Relationship between Season of Birth and Clinical Characteristics in Major Depressive Disorder in Koreans: Results from the CRESCEND Study.

We aimed to examine the potential relationship between season of birth (SOB) and clinical characteristics in Korean patients with unipolar non-psychotic major depressive disorder (MDD). Using data from the Clinical Research Center for Depression (CRESCEND) study in South Korea, 891 MDD patients were divided into two groups, those born in spring/summer (n=457) and those born in autumn/winter (n=434). Measurement tools comprising the Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Brief Psychiatric Rating Scale, Scale for Suicidal Ideation, Clinical Global Impression of severity, Social and Occupation Functional Assessment Scale, WHO Quality of Life assessment instrument-abbreviated version, Alcohol Use Disorder Identification Test, and Temperament and Character Inventory were used to evaluate depression, anxiety, overall symptoms, suicidal ideation, global severity, social function, quality of life, drinking, and temperament and character, respectively. Using independent t-tests for continuous variables and χ² tests for discrete variables, the clinical characteristics of the two groups were compared. MDD patients born in spring/summer were on average younger at onset of first depressive episode (t=2.084, p=0.038), had greater loss of concentration (χ²=4.589, p=0.032), and were more self-directed (t=2.256, p=0.025) than those born in autumn/winter. Clinically, there was a trend for the MDD patients born in spring/summer to display the contradictory characteristics of more severe clinical course and less illness burden; this may have been partly due to a paradoxical effect of the 5-HT system.

Ethnicity and cardiovascular health inequalities in people with severe mental illnesses: protocol for the E-CHASM study.

PURPOSE: People with severe mental illnesses (SMI) experience a 17- to 20-year reduction in life expectancy. One-third of deaths are due to cardiovascular disease. This study will establish the relationship of SMI with cardiovascular disease in ethnic minority groups (Indian, Pakistani, Bangladeshi, black Caribbean, black African and Irish), in the UK. METHODS: E-CHASM is a mixed methods study utilising data from 1.25 million electronic patient records. Secondary analysis of routine patient records will establish if differences in cause-specific mortality, cardiovascular disease prevalence and disparities in accessing healthcare for ethnic minority people living with SMI exist. A nested qualitative study will be used to assess barriers to accessing healthcare, both from the perspectives of service users and providers. RESULTS: In primary care, 993,116 individuals, aged 18+, provided data from 186/189 (98 %) practices in four inner-city boroughs (local government areas) in London. Prevalence of SMI according to primary care records, ranged from 1.3-1.7 %, across boroughs. The primary care sample included Bangladeshi [n = 94,643 (10 %)], Indian [n = 6086 (6 %)], Pakistani [n = 35,596 (4 %)], black Caribbean [n = 45,013 (5 %)], black African [n = 75,454 (8 %)] and Irish people [n = 13,745 (1 %)]. In the secondary care database, 12,432 individuals with SMI over 2007-2013 contributed information; prevalent diagnoses were schizophrenia [n = 6805 (55 %)], schizoaffective disorders [n = 1438 (12 %)] and bipolar affective disorder [n = 4112 (33 %)]. Largest ethnic minority groups in this sample were black Caribbean [1432 (12 %)] and black African (1393 (11 %)). CONCLUSIONS: There is a dearth of research examining cardiovascular disease in minority ethnic groups with severe mental illnesses. The E-CHASM study will address this knowledge gap.

Carers' representations of affective mental disorders in British Chinese communities.

Infrequent use of and delayed presentation to professional services have increased the burden of mental illness in minority ethnic communities. Within the growing literature on informal carers, the Chinese remain relatively unstudied. This article reports a qualitative study of 14 carers to explore illness representations of affective disorders in British Chinese communities. Firstly, it places the study within a theoretical framework that permits an understanding of mental health and illness in different sociocultural belief systems. Next, it presents carers' narrative accounts in conceptualising mental illness, including its causes, manifestations and impact on patients and carers, and contextualises the findings within the existing literature. Finally, the article examines how the caring role may be constructed from the broader social experience of carers and their relationships within a community structure that values the group over the individual. Coping mechanisms are discussed in the context of the practice of caring as a moral obligation and of policy implications for more culturally appropriate support services for both Chinese carers and mental health patients.

Family involvement in Chinese immigrants with bipolar disorder in New Zealand.

AIM: To explore the dynamic between Chinese people with bipolar disorder (BD) and family functioning. METHODS: Nine New Zealand Chinese with BD were interviewed. Data analysis was guided by content and thematic approaches. RESULTS: Four themes summarised from the interviews included: (1) family members are the primary resource; (2) many facets of recovery from BD is integrally linked with caregiving; (3) quality of family relationships is associated with acceptance of the illness; and (4) perception of caregiver burden motivates self-care. CONCLUSION: The findings support the need for mechanism that can minimise the risk of adverse family functioning associated with BD and the need of professional involvement when working with these families.

Ethnic disparities in the perception of ethical risks from psychiatric genetic studies.

To examine if ethnic differences in concerns about unfavorable consequences from psychiatric genetic studies, existing between non-Hispanic Black and White populations, persist among participants in an actual genetic study of bipolar disorder. Historically, minority subjects have been less willing to participate in such studies. Participants in the US Bipolar Genome Study (BIGS) were assessed on six items of concerns in the Questionnaire on Genetic Risk (QGR). Each item had five response categories, ranging from "not at all" concerned to "very concerned." Responses from Black (N = 188) and White participants (N = 1,065) formed the base for this analysis. Concerns about unfavorable consequences of conducting psychiatric genetic studies were prevalent in the whole sample. Concern for medical insurance was most prevalent (63.4%), followed by job concern (58.8%) and stigma (57.4%). Racial discrimination was less prevalent (28.1%). Blacks endorsed significantly stronger concerns for all consequences except the medical insurance item (P < 0.008). The most significant ethnic disparity in concerns was for racial discrimination (P < 0.0001). Associations between levels of concern and ethnicity remained significant after adjustments for other factors in multivariate models. Ethnic differences (Blacks vs. Whites) in perceived concerns about unfavorable consequences from participation persist among participants in an actual psychiatric genetic study. This suggests that other factors may play a more critical role in the decision not to participate. Future studies should investigate more comprehensive sources of barriers to consenting for ongoing psychiatric genetic studies in representative samples, incorporating assessments from non-participants as well as participants.

Impact of geographical and cultural factors on clinical trials in acute mania: lessons from a ziprasidone and haloperidol placebo-controlled study.

Clinical trials today are conducted in multiple countries to enhance patient recruitment and improve efficiency of trials. However, the demographic and cultural diversity may contribute to variations in study outcomes. Here we conducted post-hoc analyses for a placebo-controlled study with ziprasidone and haloperidol for the treatment of acute mania to address the demographic, dosing, and outcome disparities in India, Russia and the USA. We compared the baseline characteristics, outcomes and discontinuations in patients and explored the relationship between the outcome measures across these countries. We found substantial differences in baseline characteristics of subjects, administered dosage and disease severity in India compared to the USA and Russia. Conversely, US subjects had a higher placebo response compared to subjects in Russia and India. These results are probably due to demographic differences in patient populations and psychiatric clinical practice across countries. While we offer initial ideas to address the disparities identified in this analysis, it is clear that further research to improve our understanding of geographical differences is essential to ensure globally applicable results for clinical trials in psychiatry.

Longitudinal racial/ethnic disparities in antimanic medication use in bipolar-I disorder.

OBJECTIVE: To examine racial/ethnic longitudinal disparities in antimanic medication use among adults with bipolar-I disorder. METHODS: Observational study using administrative data from Florida's Medicaid program, July 1997 to June 2005, for enrollees diagnosed with bipolar-I disorder (N = 13,497 persons; 126,413 person-quarters). We examined the likelihood of receiving one of the following during a given quarter: (1) any antimanic agent (antipsychotic or mood stabilizer) or none, and (2) mood stabilizers, antipsychotic monotherapy, or neither. Binary and multinomial logistic regression models predicted the association between race/ethnicity and prescription fills, adjusting for clinical and demographic characteristics. Cohort indicators for year that the enrollee met study criteria were included to account for cohort effects. RESULTS: Averaging over all cohorts and quarters, compared with whites, blacks had lower odds of filling any antimanic and mood stabilizer prescriptions specifically (40%-49% and 47%-63%, respectively), but similar odds of filling prescriptions for antipsychotic monotherapy. After Bonferroni adjustment, compared with whites, there were no statistically significant disparities for Hispanics in filling prescriptions for any, or specific antimanic medications. CONCLUSIONS: Rates of antimanic medication use were low regardless of race/ethnicity. However, we found disparities in antimanic medication use for blacks compared with whites and these disparities persisted over time. We found no Hispanic-white disparities. Quality improvement efforts should focus on all individuals with bipolar disorder, but particular attention should be paid to understanding disparities in medication use for blacks.

Cultural aspects of bipolar disorder: Interpersonal meaning for clients & psychiatric nurses.

Bipolar disorder is a complicated mental illness to diagnose and treat. The symptoms of the disorder cause a multitude of fluctuations in mood and behavior, affecting the way individuals function and interact with others on a daily basis. Individuals diagnosed with bipolar disorder experience symptoms within a framework that is grounded in their cultural beliefs, values, and norms. Culture is a complex and personal biopsychosocial phenomenon that provides meaning within life for an individual, a group, or a community. It is essential that psychiatric-mental health (PMH) nurses understand the role of culture and integrate this knowledge into the biopsychosocial care of clients. The development and maintenance of the interpersonal therapeutic relationship between PMH nurses and their clients requires the use of a cultural framework, which refers to the connection of culture and cultural competence. The purposes of this article are to define culture and the process of cultural competence, provide a brief overview of bipolar disorder, propose the use of a cultural framework for bipolar disorder, and discuss the implications for PMH nurses who care for culturally and ethnically diverse clients.

Analysis of U.S. trends in discharges from general hospitals for episodes of serious mental illness, 1995-2002.

OBJECTIVE: The aim of this study was to ascertain trends from 1995 to 2002 in general hospital discharges among adults in the United States with serious mental illness. METHODS: As of 2002 the National Hospital Discharge Survey collected data on approximately 327,000 discharges from 445 hospitals. ICD-9-CM codes were used to identify the discharges between 1995 and 2002 associated with serious mental illness. RESULTS: Annual discharge rates involving serious mental illness increased by 34.7%, from 29.1 discharges per 10,000 in the U.S. adult population (18 years and older) in 1995 to 39.2 discharges per 10,000 in the U.S. adult population in 2002. Hospital discharges involving serious mental illness increased significantly in the black population and among young adults. For adults of ages 18 to 24, discharges per 10,000 increased from 19.9 in 1995 to 42.3 in 2002. A substantial increasing trend was seen for the Northeast and South census regions. There was an increase in the proportion of discharges associated with hospitalizations for serious mental illness that were covered by private payers, whereas there was a significant decline in such discharges when patients were covered by government programs. CONCLUSIONS: The increasing trend in general hospital discharges involving serious mental illness has continued into recent years. Further investigations are needed to understand how patient- and system-level factors have contributed to the increasing trend in general hospital discharges involving an episode of serious mental illness.

CAOS contribution to understanding cultural/ethnic differences in the prevalence of bipolar affective disorder in New Zealand.

OBJECTIVE: To examine whether data on the clinical profiles of psychiatric service users can inform the claim that Maori in the New Zealand community have an increased rate of bipolar disorder. METHOD: The standardized recordings of a variety of clinical phenomena previously collected in a New Zealand study of psychiatric service users was extracted for those persons who were diagnosed with a bipolar mental disorder. The individual clinical phenomena were then compared by ethnicity. RESULTS: The most dramatic result was the increased recording of high levels of overactivity or disruptive aggressive behaviour in Maori compared with European in psychiatric service users, despite which, the rates of the disorder did not significantly differ by ethnicity. CONCLUSION: In the community survey lay raters were deciding on the presence or absence of phenomena including hyperactivity without the contextual knowledge that clinicians use. It is possible that the Composite International Diagnostic Interview decision tree was being fed an excessive amount of that criterion.

Treatment characteristics and illness burden among European Americans, African Americans, and Latinos in the first 2,000 patients of the systematic treatment enhancement program for bipolar disorder.

OBJECTIVE: Across ethnicity/race, prevalence rates of bipolar disorder are similar. However, African Americans and Latinos may receive less specialty mental health treatment and different medications, and may be less adherent to treatment regimens than European American patients. This study compared illness characteristics, treatment history, and overall functioning in a sample of European American, African American, and Latino patients with bipolar disorder. METHODS: The samples were drawn from the first 2,000 patients enrolled in the Systematic Treatment Enhancement Program for Bipolar Disorder. There were 1,686 European Americans, 65 African Americans, and 77 Latinos. The data were collected upon study entry, with structured interviews, clinicianrated forms, and self report. RESULTS: African Americans had a greater likelihood of psychosis and fewer psychiatric medication prescriptions than did European Americans. Latinos had greater alcohol comorbidity, fewer psychiatric medication prescriptions and specialty treatment visits, and more frequent religious service attendance than did European Americans. Depression and manic episode severity and functional outcomes were similar across groups. CONCLUSIONS: Patients with bipolar disorder who are members of ethnic/racial minority groups continue to receive less intensive specialized mental health treatment than do European American patients. These findings may be related to provider, patient, or provider-patient relationship variables. Despite treatment differences and greater comorbidity and sympomatology, there were no differences among the three groups in overall functioning, suggesting additional outcome measurement is warranted.

Culture and assessment of manic symptoms.

Cultural background may influence the perception of psychiatric symptoms. We examined the effects of cultural biases on the identification of manic symptoms using the Young Mania Rating Scale. Two video interviews, each with an American person with mania, were shown to psychiatrists from three countries (US, UK and India). Total scores on the scale differed significantly between the US and UK (P<0.001) and between India and UK (P<0.001) rater groups. Overall, differences between India and US rater groups were less marked (P=0.28). These differences suggest that cultural biases influence the interpretation of manic symptoms.

The HCL-32: towards a self-assessment tool for hypomanic symptoms in outpatients.

BACKGROUND: Bipolar disorders (BP) are frequently diagnosed and treated as pure depression initially; accurate diagnosis often being delayed by 8 to 10 years. In prospective studies, the presence of hypomanic symptoms in adolescence is strongly predictive of later bipolar disorders. As such, an instrument for self-assessment of hypomanic symptoms might increase the detection of suspected and of manifest, but under-treated, cases of bipolar disorders. METHODS: The multi-lingual hypomania checklist (HCL-32) has been developed and is being tested internationally. This preliminary paper reports the performance of the scale in distinguishing individuals with BP (N=266) from those with major depressive disorder (MDD; N=160). The samples were adult psychiatry patients recruited in Italy (N=186) and Sweden (N=240). RESULTS: The samples reported similar clinical profiles and the structure for the HCL-32 demonstrated two main factors identified as "active/elated" hypomania and "risk-taking/irritable" hypomania. The HCL-32 distinguished between BP and MDD with a sensitivity of 80% and a specificity of 51%. LIMITATIONS: Although the HCL-32 is a sensitive instrument for hypomanic symptoms, it does not distinguish between BP-I and BP-II disorders. CONCLUSIONS: Future studies should test if different combinations of items, possibly recording the consequences of hypomania, can distinguish between these BP subtypes.

Use of mental health services by Asian Americans.

This study explored the use of mental health services by Asian Americans and other ethnic populations (N=104,773) in California. The authors used linear regression analyses to assess the role of ethnicity and diagnosis in predicting six-month use of services. East Asians used more services than Southeast Asians, Filipinos, other Asians, Caucasians, African Americans, Latinos, and Native Americans, even when severity of illness was taken into account. The findings suggest that aggregating Asian subpopulations into a single group in services research is no longer appropriate. Attention needs to be placed on the needs of Southeast Asians and other Asians, whose service use patterns approximate those of the traditionally most underserved groups, African Americans and Latinos.

Pathways to care for patients with bipolar disorder.

Bipolar disorder is a chronic, debilitating psychiatric illness with serious ramifications for patients, their families, and society. Despite the availability of effective treatments, this disease often goes untreated due to medical, financial, legal/governmental, and cultural barriers. In this review we explore possible reasons for this problem. Misdiagnosis of bipolar disorders is a common medical barrier. One pathway to care for individuals with bipolar disorder is through referral from primary care, but primary care physicians generally have not received special training in the recognition and management of bipolar disorder. This often leads to diagnostic delays or errors, which prevents timely 'filtering' of patients into specialized care. Using data bases we explored these pathways. Legislation in the USA, such as the Emergency Medical Treatment and Active Labor Act (EMTALA), designed to ensure access to inpatient mental health care, has instead given hospitals financial incentives to limit inpatient mental health care capacities. Reimbursement of mental health care expenses is a significant issue impacting a patient's ability to gain access to care, as bipolar disorder is a costly disease to treat. Improving access to care among the bipolar community will require multilateral strategies to influence the actions and attitudes of patients, communities, providers, health care systems, and state/national governments. In other cultures, barriers to care differ according to a number of factors such as type of services, explanatory models of illness, misdiagnosis and perceptions of care givers. It is essential that clinicians are aware of pathways and barriers so that appropriate and accessible care can be provided.
