Cancer-related mortality in people with mental illness

CONTEXT There is a 30% higher case fatality rate from cancer in psychiatric patients even though their incidence of cancer is no greater than in the general population. The reasons are unclear, but if increased cancer mortality were due to lifestyle only, cancer incidence should be similarly increased. Other hypotheses include delays in presentation, leading to more advanced staging at diagnosis, and difficulties in treatment access following diagnosis. OBJECTIVE To assess why psychiatric patients are no more likely than the general population to develop cancer but are more likely to die of it. DESIGN, SETTING, AND PATIENTS A population-based record-linkage analysis compared psychiatric patients with the Western Australian population, using an inception cohort to calculate rates and hazard ratios. Mental health records were linked with cancer registrations and death records from January 1, 1988, to December 31, 2007, in Western Australia. MAIN OUTCOME MEASURES Metastases, incidence, mortality, and access to cancer interventions. RESULTS There were 6586 new cancers in psychiatric patients. Cancer incidence was lower in psychiatric patients than in the general population in both males (rate ratio = 0.86; 95% CI, 0.82-0.90) and females (rate ratio = 0.92; 95% CI, 0.88-0.96), although mortality was higher (males: rate ratio = 1.52; 95% CI, 1.45-1.60; females: rate ratio = 1.29; 95% CI, 1.22-1.36). The proportion of cancer with metastases at presentation was significantly higher in psychiatric patients (7.1%; 95% CI, 6.5%-7.8%) than in the general population (6.1%; 95% CI, 6.0%-6.2%). Psychiatric patients had a reduced likelihood of surgery (hazard ratio = 0.81; 95% CI, 0.76-0.86), especially resection of colorectal, breast, and cervical cancers. They also received significantly less radiotherapy for breast, colorectal, and uterine cancers and fewer chemotherapy sessions. CONCLUSIONS Although incidence is no higher than in the general population, psychiatric patients are more likely to have metastases at diagnosis and less likely to receive specialized interventions. This may explain their greater case fatality and highlights the need for improved cancer screening and detection.

The effect of study design on the reporting of mortality due to colorectal cancer in adults with mental illness in Nova Scotia

OBJECTIVE

Some studies suggest a higher case fatality from colorectal cancer (CRC) in psychiatric patients even though the incidence is no greater than in the general population. However, this finding is not universal and may be confounded by study design (for example, inception, compared with historical, cohort), mean cohort age, or delays in presentation with more advanced staging at diagnosis. We assessed how study design and cancer stage at presentation affected outcomes in psychiatric patients.

METHODS

A retrospective historical cohort of CRC presentations was used comparing psychiatric patients with control subjects. Psychiatric status was defined by either health service use or psychotropic prescription, and outcomes by logistic or Cox proportional hazards regression.

RESULTS

There were 3501 new presentations of CRC from 2001 to 2005. Psychiatric cases, as defined by in- or outpatient contacts, made up 15.9% (n = 558) of patients with CRC. There was no association between psychiatric status and stage at presentation, surgical intervention, or mortality after adjusting for confounders. There was a reduced likelihood of resection, an indicator of curative treatment, when on a selective serotonin reuptake inhibitor or serotonin noradrenergic reuptake inhibitor (n = 194; AOR 0.54; 95% CI 0.30 to 0.97) or antipsychotics (n = 28; AOR 0.27; 95% CI 0.08 to 0.92).

CONCLUSIONS

The association between psychiatric status and CRC may vary by study design and how psychiatric status is defined. These factors should be considered when interpreting any association between mental illness and cancer. As in studies of all-cause and cardiac mortality, historical cohorts of prevalent psychiatric cases may be less sensitive than inception cohorts of new patients, possibly because the excess of deaths is greatest within 7 years of initial presentation for a psychiatric disorder.

The potential impact of smoke-free facilities on smoking cessation in people with mental illness

OBJECTIVE

The aim of this paper was to estimate the degree to which smoke-free facilities may facilitate smoking cessation in smokers with mental illness by estimating the proportion of smokers with mental illness who receive inpatient treatment, their smoking rates and average durations of stay.

METHOD

Smoking and hospitalization rates were estimated from the Australian National Survey of Mental Health and Wellbeing. Information on duration of inpatient treatment was calculated from the Western Australian Mental Health Information System.

RESULTS

Of Australia's estimated 3,567,000 current adult smokers, 32.4% had a mental illness in the past 12 months, and 66.6% had a lifetime mental illness. However, only 1.4% of smokers were hospitalized for a mental health problem in the past 12 months, and 6.3% had ever been hospitalized for a mental health problem. Of those hospitalized for mental health treatment in the past 12 months, 61.2% were current smokers. In 2007 median duration of inpatient mental health admissions was 1 day, and 57% of admissions had duration of 2 days or less.

CONCLUSIONS

The majority of smokers with mental illness are not treated in inpatient facilities, and where inpatient admissions occur they are generally of short duration. While smoking cessation is an important goal in treatment of smokers with mental illness, support after discharge from inpatient care is important for longer term cessation. Other strategies will be required to support smoking cessation efforts for the majority of smokers with mental illness not in contact with mental health services.

Can we use medical examiners’ records for suicide surveillance and prevention research in Nova Scotia?

Introduction

Medical examiners’ records can contribute to our understanding of the extent of suicide in a population, as well as associated sociodemographic and other factors.

Methods

Using a mixed methods approach, the key objective of this pilot study was to determine the sources and types of information found in the Nova Scotia Medical Examiner Service (NSMES) records that might inform suicide surveillance and targeted prevention efforts. A secondary objective was to describe the one-year cohort of 108 individuals who died by suicide in 2006 in terms of available sociodemographic information and health care use in the year prior to death.

Results

Data extraction revealed inconsistencies both across and within files in terms of the types and amounts of sociodemographic and other data collected, preventing correlational analyses. However, linkage of the records to administrative databases revealed frequent health care use in the month prior to death.

Conclusion

The introduction of systematic data collection to NSMES investigations may yield a comprehensive dataset useful for policy development and population level research.

Critically appraising qualitative research: a guide for clinicians more familiar with quantitative techniques

OBJECTIVES

Papers using qualitative methods are increasingly common in psychiatric journals. This overview is an introduction to critically appraising a qualitative paper for clinicians who are more familiar with quantitative methods.

CONCLUSIONS

Qualitative research uses data from interviews (semi-structured or unstructured), focus groups, observations or written materials. Data analysis is inductive, allowing meaning to emerge from the data, rather than the more deductive, hypothesis centred approach of quantitative research. This overview compares and contrasts quantitative and qualitative research methods. Quantitative concepts such as reliability, validity, statistical power, bias and generalisability have qualitative equivalents. These include triangulation, trustworthiness, saturation, reflexivity and applicability. Reflexivity also shares features of transference. Qualitative approaches include: ethnography, action-assessment, grounded theory, case studies and mixed methods. Qualitative research can complement quantitative approaches. An understanding of both is useful in critically appraising the psychiatric literature.

Factors associated with not seeking professional help or disclosing intent prior to suicide: a study of medical examiners' records in Nova Scotia

OBJECTIVE

Individual-level data from clinical settings lack information on people who did not seek professional help prior to suicide. We used records of the Nova Scotia Medical Examiner Service (NSMES) to compare people who had contact with a health professional prior to suicide with those who did not.

METHOD

We linked data from the NSMES to routine administrative data of the province.

RESULTS

The NSMES recorded 108 suicides in Nova Scotia from January 1, 2006, to December 31, 2006; there were 90 male and 18 female suicide deaths. Mean and median age at death were 44.73 (SD 13.33) and 44 years, respectively. Patients aged 40 to 49 years made up one-third of the cases (n = 35) and this was the decade of life with the highest number of suicides. This was also the group least likely to have suicidal intent recorded in the NSMES files (χ(2) = 3.86, df = 1, P = 0.05). Otherwise, there were no significant differences between people who sought help, or disclosed intent, prior to suicide and people who did not. The samples in all cases were predominately male and single.

CONCLUSIONS

People aged 40 to 49 years were the age group with the highest absolute number of suicides, but were the least likely to have suicidal intent recorded in the NSMES files. This finding merits further investigation. Medical examiner or coroner data may provide additional information not obtained elsewhere for the surveillance of suicide.

The development of community health indicators: a district-wide approach

INTRODUCTION

In response to high rates of chronic disease, the Capital District Health Authority in Nova Scotia recognized a need to move from a focus on acute care in decision making to one that also values a population health approach guided by community health indicators.

METHODS

Stakeholders were surveyed on the choice, knowledge and utility of selected indicators.

RESULTS

Respondents reported high scores for changes in their knowledge and attitude regarding community health indicators, and identified priority indicators for action.Decision makers' use of community health indicators was increased by stakeholder involvement, supporting evidence in plain language, and wide dissemination.

The epidemiology of excess mortality in people with mental illness

OBJECTIVE

to investigate the burden of excess mortality among people with mental illness in developed countries, how it is distributed, and whether it has changed over time.

METHOD

we conducted a systematic search of MEDLINE, restricting our attention to peer-reviewed studies and reviews published in English relating to mortality and mental illness. Because of the large number of studies that have been undertaken during the last 30 years, we have selected a representative cross-section of studies for inclusion in our review.

RESULTS

there is substantial excess mortality in people with mental illness for almost all psychiatric disorders and all main causes of death. Consistently elevated rates have been observed across settings and over time. The highest numbers of excess deaths are due to cardiovascular and respiratory diseases. With life expectancy increasing in the general population, the disparity in mortality outcomes for people with mental illness is increasing.

CONCLUSIONS

without the development of alternative approaches to promoting and treating the physical health of people with mental illness, it is possible that the disparity in mortality outcomes will persist.

Inequalities in healthcare provision for people with severe mental illness

There are many factors that contribute to the poor physical health of people with severe mental illness (SMI), including lifestyle factors and medication side effects. However, there is increasing evidence that disparities in healthcare provision contribute to poor physical health outcomes. These inequalities have been attributed to a combination of factors including systemic issues, such as the separation of mental health services from other medical services, healthcare provider issues including the pervasive stigma associated with mental illness, and consequences of mental illness and side effects of its treatment. A number of solutions have been proposed. To tackle systemic barriers to healthcare provision integrated care models could be employed including co-location of physical and mental health services or the use of case managers or other staff to undertake a co-ordination or liaison role between services. The health care sector could be targeted for programmes aimed at reducing the stigma of mental illness. The cognitive deficits and other consequences of SMI could be addressed through the provision of healthcare skills training to people with SMI or by the use of peer supporters. Population health and health promotion approaches could be developed and targeted at this population, by integrating health promotion activities across domains of interest. To date there have only been small-scale trials to evaluate these ideas suggesting that a range of models may have benefit. More work is needed to build the evidence base in this area.

A controlled before-and-after evaluation of a mobile crisis partnership between mental health and police services in Nova Scotia

OBJECTIVES

Police are often the front-line response to people experiencing mental health crises. This study examined the impact of an integrated mobile crisis team formed in partnership between mental health services, municipal police, and emergency health services. The service offered short-term crisis management, with mobile interventions being attended by a plainclothes police officer and a mental health professional.

METHODS

We used a mixed-methods design encompassing: a controlled before-and-after quantitative comparison of the intervention area with a control area without access to such a service, for 1 year before and 2 years after program implementation; and qualitative assessments of the views of service recipients, families, police officers, and health staff at baseline and 2 years afterward.

RESULTS

The integrated service resulted in increased use by people in crisis, families, and service partners (for example, from 464 to 1666 service recipients per year). Despite increased service use, time spent on-scene and call-to-door time were reduced. At year 2, the time spent on-scene by police (136 minutes) was significantly lower than in the control area (165 minutes) (Student t test = 3.4, df = 1649, P < 0.001). After adjusting for confounders, people seen by the integrated team (n = 295) showed greater engagement than control subjects as measured by outpatient contacts (b = 1.3, chi square = 92.7, df = 1, P < 0.001). The service data findings were supported by the qualitative results of focus groups and interviews.

CONCLUSIONS

Partnerships between the police department and mental health system can improve collaboration, efficiency, and the treatment of people with mental illness.

Do the Health of the Nation Outcome Scales measure outcome?

OBJECTIVE

Among mental health outcome measures that have been developed for routine use, most of the information concerns the Health of the Nation Outcome Scales (HoNOS). This instrument is widely used in Europe, Australia, and New Zealand, but not in Canada. We tested its sensitivity and predictive validity under conditions that would resemble, as closely as possible, routine use.

METHOD

Treating clinicians were asked to assess patients of all ages referred to outpatient mental health facilities of 2 district health authorities in Nova Scotia using either the HoNOS for adults or the HoNOS for Children and Adolescents (HoNOSCA). Data were entered using the existing routine administrative data system.

RESULTS

We obtained at least 1 rating on 4620 patients, giving a completion rate of 82%. On follow-up, ratings for the global score and most of the individual items were sensitive to change (n = 808). After adjusting for confounders, a baseline HoNOS score was significantly associated with subsequent in and outpatient service use including admissions, bed days, and psychiatric contacts (n = 1359).

CONCLUSIONS

HoNOS has satisfactory sensitivity and predictive validity for routine use. We could introduce the adult version and HoNOSCA simultaneously and collect data using routine databases. Given the widespread routine use of HoNOS internationally, using the same outcome measure in Canada would enable comparisons of illness severity and outcomes between jurisdictions.

Short-term psychodynamic psychotherapy for somatic disorders. Systematic review and meta-analysis of clinical trials

BACKGROUND

Somatic symptom disorders are common, disabling and costly. Individually provided short-term psychodynamic psychotherapies (STPP) have shown promising results. However, the effectiveness of STPP for somatic symptom disorders has not been reviewed.

METHODS

We undertook a systematic review of randomized controlled trials and controlled before and after studies. The outcomes included psychological symptoms, physical symptoms, social-occupational function, healthcare utilization and treatment continuation.

RESULTS

A total of 23 studies met the inclusion criteria and covered a broad range of somatic disorders. Thirteen were RCTs and 10 were case series with pre-post outcome assessment. Of the included studies, 21/23 (91.3%), 11/12 (91.6%), 16/19 (76.2%) and 7/9 (77.8%) reported significant or possible effects on physical symptoms, psychological symptoms, social-occupational function and healthcare utilization respectively. Meta-analysis was possible for 14 studies and revealed significant effects on physical symptoms, psychiatric symptoms and social adjustment which were maintained in long-term follow-up. Random-effect modeling attenuated some of these relationships. There was a 54% greater treatment retention in the STPP group versus controls.

CONCLUSION

STPP may be effective for a range of medical and physical conditions underscoring the role of patients' emotional adjustment in overall health. Future research should include high-quality randomized and clinical effectiveness studies with attention to healthcare use and costs.

Assessing the quality of randomized controlled trials examining psychological interventions for pediatric procedural pain: recommendations for quality improvement

OBJECTIVE

Systematic reviews of randomized controlled trials (RCTs) support the efficacy of psychological interventions for procedural pain management. However, methodological limitations (e.g., inadequate randomization) have affected the quality of this research, thereby weakening RCT findings.

METHODS

Detailed quality coding was conducted on 28 RCTs included in a systematic review of psychological interventions for pediatric procedural pain.

RESULTS

The majority of RCTs were of poor to low quality (criteria reported in <50% of RCTs). Commonly reported criteria addressed study background, conditions, statistical analyses, and interpretation of results. Commonly nonreported criteria included treatment administration, evaluation of treatment efficacy (effect sizes, summary statistics, intention-to-treat analyses), caregiver demographics, follow-up, and participant flow. Quality was greater in more recent trials, and did not vary by journal type (psychology vs. medical).

CONCLUSION

Despite poor quality ratings, quality reporting in psychological RCTs for pediatric procedural pain has improved over time. Recommendations for quality enhancement are provided.

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

BACKGROUND

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

AIMS

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

METHOD

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

RESULTS

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

CONCLUSIONS

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

Use of administrative data for the surveillance of mood and anxiety disorders

OBJECTIVE

There is increasing interest in the use of administrative data for surveillance and research in Australia. The purpose of the present study was to evaluate the usefulness of such data for the surveillance of mood and anxiety disorder using databases from the following Canadian provinces: British Columbia, Ontario, Quebec and Nova Scotia.

METHOD

A population-based record-linkage analysis was done using data from physician billings and hospital discharge abstracts, and community-based clinics using a case definition of ICD-9 diagnoses of 296.0-296.9, 311.0, and 300.0-300.9.

RESULTS

The prevalence of treated mood and/or anxiety disorder was similar in Nova Scotia, British Columbia, and Ontario at approximately 10%. The prevalence for Quebec was slightly lower at 8%. Findings from the provinces showed consistency across age and sex despite variations in data coding. Women tended to show a higher prevalence overall of mood and anxiety disorder than men. There was considerably more variation, however, when treated anxiety (300.0-300.9) and mood disorders (296.0-296.9, 311.0) were considered separately. Prevalence increased steadily to middle age, declining in the 50s and 60s, and then increased after 70 years of age.

CONCLUSIONS

Administrative data can provide a useful, reliable and economical source of information for the surveillance of treated mood and/or anxiety disorder. Due to the lack of specificity, however, in the diagnoses and data capture, it may be difficult to conduct surveillance of mood and anxiety disorders as separate entities. These findings may have implications for the surveillance of mood and anxiety disorders in Australia with the development of a national network for the extraction, linkage and analysis of administrative data.

Use of administrative data for the surveillance of mental disorders in 5 provinces

OBJECTIVE

To evaluate the usefulness of administrative data for the surveillance of mental illness in Canada using databases in the following 5 provinces: British Columbia, Ontario, Quebec, Nova Scotia, and Alberta.

METHOD

We used a population-based record-linkage analysis with data from physician billings, hospital discharge abstracts, and community-based clinics. The following diagnostic codes from the International Classification of Diseases, Ninth Edition, were used to define cases: 290 to 319, inclusive.

RESULTS

The prevalence of treated psychiatric disorder was similar in Nova Scotia, British Columbia, Alberta, and Ontario at about 15%. The prevalence for Quebec was slightly lower at 12%. Findings from the provinces showed remarkable consistency across age and sex, despite variations in data coding. Women tended to show a higher prevalence overall of treated mental disorders than men. Prevalence increased steadily to middle age, declining in the 50s and 60s, and then increasing again after age 70 years.

CONCLUSIONS

Provincial and territorial administrative data can provide a useful, reliable, and economical source of information for the surveillance of treated mental disorders. Such a surveillance system can provide longitudinal data at little cost to support health service provision and planning.

Shared mental health care for a marginalized community in inner-city Canada

OBJECTIVES

This paper describes the experience and evaluation of a shared care project targeted at marginalized individuals living in the North End of Halifax, Nova Scotia. This population has high rates of psychiatric disorder, often comorbid with chronic medical conditions, and people have difficulty in obtaining the help they need. This primary care liaison service covers all ages and includes outreach to emergency shelters, transitional housing and drop-in centres. Collaborative care improved access, satisfaction and outcomes for marginalized individuals in urban settings. Primary care providers with access to the service reported greater comfort in dealing with mental health problems, and satisfaction with collaborative care, as well as mental health services in general. Results were significantly better than those of control practices when such data were available. The median wait time was 6 days in comparison with 39.5 days for the comparison site.

CONCLUSIONS

This model can complement other initiatives to improve the health of marginalized populations, and may be relevant to Australia.

An epidemiologic study of psychotropic medication and obesity-related chronic illnesses in older psychiatric patients

OBJECTIVE

Adverse effects from medication vary with age. Weight gain with several psychotropics is well known in adults but less information is available related to extent and complications of psychotropic-induced weight gain in older psychiatric patients. We determined the relative incidence of 2 obesity-related conditions (diabetes and hypertension) in older psychiatric patients receiving antipsychotics, antidepressants, and mood stabilizers.

METHOD

A population-based case-control study of all psychiatric patients aged 67 years or older in contact with either specialist services or primary care using administrative data from Nova Scotia.

RESULTS

We identified incident cases of diabetes (n = 608) and of hypertension (n = 1056), as well as an equal number of control subjects for each condition. Amitryptiline, selective serotonin reuptake inhibitors (SSRIs), and olanzapine were associated with an increased risk of presenting with hypertension 6 months after initial prescription. By contrast, conventional antipsychotics were associated with a reduced incidence of hypertension. Olanzapine was also significantly associated with diabetes after 6 months (OR adj = 2.58, 95% CI 1.12 to 5.92). The findings for SSRIs and olanzapine remained significant after adjusting for potential confounders such as sociodemographic characteristics, schizophrenia, beta blockers, thiazide diuretics, and corticosteroids.

CONCLUSIONS

Our results suggest that the association of psychotropics and 2 obesity-related conditions, hypertension and diabetes, applies to older psychiatric patients as well as younger populations. Within drug classes, there are drugs that have a greater association than others, and this may be a factor when choosing a specific agent.

Conditional release in Western Australia: effect on hospital length of stay

OBJECTIVE

The goal of this study was to determine whether the introduction of community treatment orders, which allow for conditional release from a psychiatric hospital, reduced inpatient episode durations in Western Australia by providing an alternative to extended inpatient stays.

METHODS

The design compared 129 persons given community treatment orders and 117 matched control patients without such orders-all of whom were hospitalized during the same period both before and after the introduction of the community treatment order law that allows for conditional release. A multivariate analysis of covariance was used to evaluate the impact of community treatment orders on change in inpatient episode duration.

RESULTS

The model showed a significant effect on inpatient episode duration (R(2)=.23, adjusted R(2)=.17, N=243, F=3.99, df=17 and 226, p<.001), indicating that community treatment orders (after taking all control factors into account) enabled a 19.16-day reduction per episode of inpatient care (t=2.13, df=1, p=.034) for persons given conditional release. Community-initiated treatment orders intended to prevent hospitalization, yet failing to do so, were associated with increased duration of subsequent hospitalizations (35.18 days; t=-3.36, df=1, p<.001).

CONCLUSIONS

Community treatment orders can be a useful tool for some but not necessarily all objectives. In the form of conditional release, orders reduce the likelihood of extended hospital stays. As a means to prevent hospitalization, the utility of community treatment orders is more complex, being dependent on services provided and on the judicious selection of persons for these orders.
