Inequalities in lung cancer care of elderly patients with schizophrenia: an observational cohort study

The causal relationship between severe mental illness and risk of lung carcinoma

Observational studies have suggested a link between severe mental illness (SMI) and risk of lung carcinoma (LC); however, causality has not been established. In this study, we conducted a two-sample, two-step Mendelian randomization (MR) investigation to uncover the etiological influence of SMI on LC risk and quantify the mediating effects of known modifiable risk factors. We obtained summary-level datasets for schizophrenia, major depressive disorder (MDD), and bipolar disorder (BD) from the Psychiatric Genomics Consortium (PGC). Data on single nucleotide polymorphisms (SNPs) associated with lung carcinoma (LC) were sourced from a recent large meta-analysis by McKay et al. We employed two-sample MR and two-step MR utilizing the inverse variance weighted method for causal estimation. Sensitivity tests were conducted to validate causal relationships. In two-sample MR, we identified schizophrenia as a risk factor for LC (OR = 1.06, 95% CI 1.02-1.11, P = 3.48E-03), while MDD (OR = 1.18, 95% CI 0.98-1.42, P = .07) and BD (OR = 1.07, 95% CI 0.99-1.15, P = .09) showed no significant association with LC. In the two-step MR, smoking accounted for 24.66% of the schizophrenia-LC risk association, and alcohol consumption explained 7.59% of the effect. Schizophrenia is a risk factor for lung carcinoma, and smoking and alcohol consumption are the mediating factors in this causal relationship. LC screening should be emphasized in individuals with schizophrenia, particularly in those who smoke and consume alcohol regularly.

Do people with disabilities experience disparities in cancer care? A systematic review

BACKGROUND

Over 1.3 billion people, or 16% of the world's population, live with some form of disability. Recent studies have reported that people with disabilities (PwD) might not be receiving state-of-the-art treatment for cancer as their non-disabled peers; our objective was to systematically review this topic.

METHODS

A systematic review was undertaken to compare cancer outcomes and quality of cancer care between adults with and without disabilities (NIHR Prospero register ID number: CRD42022281506). A search of the literature was performed in July 2022 across five databases: EMBASE, Medline, Cochrane Library, Web of Science and CINAHL databases. Peer-reviewed quantitative research articles, published in English from 2000 to 2022, with interventional or observational study designs, comparing cancer outcomes between a sample of adult patients with disabilities and a sample without disabilities were included. Studies focused on cancer screening and not treatment were excluded, as well as editorials, commentaries, opinion papers, reviews, case reports, case series under 10 patients and conference abstracts. Studies were evaluated by one reviewer for risk of bias based on a set of criteria according to the SIGN 50 guidelines. A narrative synthesis was conducted according to the Cochrane SWiM guidelines, with tables summarizing study characteristics and outcomes. This research received no external funding.

RESULTS

Thirty-one studies were included in the systematic review. Compared to people without disabilities, PwD had worse cancer outcomes, in terms of poorer survival and higher overall and cancer-specific mortality. There was also evidence that PwD received poorer quality cancer care, including lower access to state-of-the-art care or curative-intent therapies, treatment delays, undertreatment or excessively invasive treatment, worse access to in-hospital services, less specialist healthcare utilization, less access to pain medications and inadequate end-of-life quality of care.

DISCUSSION

Limitations of this work include the exclusion of qualitative research, no assessment of publication bias, selection performed by only one reviewer, results from high-income countries only, no meta-analysis and a high risk of bias in 15% of included studies. In spite of these limitations, our results show that PwD often experience severe disparities in cancer care with less guideline-consistent care and higher mortality than people without disabilities. These findings raise urgent questions about how to ensure equitable care for PwD; in order to prevent avoidable morbidity and mortality, cancer care programs need to be evaluated and urgently improved, with specific training of clinical staff, more disability inclusive research, better communication and shared decision-making with patients and elimination of physical, social and cultural barriers.

What health inequalities exist in access to, outcomes from and experience of treatment for lung cancer? A scoping review

OBJECTIVES

Lung cancer (LC) continues to be the leading cause of cancer-related deaths and while there have been significant improvements in overall survival, this gain is not equally distributed. To address health inequalities (HIs), it is vital to identify whether and where they exist. This paper reviews existing literature on what HIs impact LC care and where these manifest on the care pathway.

DESIGN

A systematic scoping review based on Arksey and O'Malley's five-stage framework.

DATA SOURCES

Multiple databases (EMBASE, HMIC, Medline, PsycINFO, PubMed) were used to retrieve articles.

ELIGIBILITY CRITERIA

Search limits were set to retrieve articles published between January 2012 and April 2022. Papers examining LC along with domains of HI were included. Two authors screened papers and independently assessed full texts.

DATA EXTRACTION AND SYNTHESIS

HIs were categorised according to: (a) HI domains: Protected Characteristics (PC); Socioeconomic and Deprivation Factors (SDF); Geographical Region (GR); Vulnerable or Socially Excluded Groups (VSG); and (b) where on the LC pathway (access to, outcomes from, experience of care) inequalities manifest. Data were extracted by two authors and collated in a spreadsheet for structured analysis and interpretation.

RESULTS

41 papers were included. The most studied domain was PC (32/41), followed by SDF (19/41), GR (18/41) and VSG (13/41). Most studies investigated differences in access (31/41) or outcomes (27/41), with few (4/41) exploring experience inequalities. Evidence showed race, rural residence and being part of a VSG impacted the access to LC diagnosis, treatment and supportive care. Additionally, rural residence, older age or male sex negatively impacted survival and mortality. The relationship between outcomes and other factors (eg, race, deprivation) showed mixed results.

CONCLUSIONS

Findings offer an opportunity to reflect on the understanding of HIs in LC care and provide a platform to consider targeted efforts to improve equity of access, outcomes and experience for patients.

Who are the vulnerable lung cancer patients at risk for not receiving first-line curative or palliative treatment?

BACKGROUND

To identify non-small-cell lung cancer (NSCLC) patients in need of comprehensive support, we examined the association between patient and disease-related factors of vulnerability related to not receiving guideline-recommended treatment.

MATERIAL AND METHODS

We identified 14,597 non-small-cell lung cancer (NSCLC) patients with performance status <3 during 2013-2018 in the Danish Lung Cancer Registry. Multivariate logistic regression models were used to estimate Odds Ratios (ORs) and 95% confidence intervals (CIs) for receiving guideline-recommended treatment according to stage, comorbidities, age, performance status, long distance to hospital, cohabitation status, education and alcohol abuse.

RESULTS

21% of stage I-IIIA NSCLC patients did not receive curative treatment while 10% with stage IIIB-IV did not receive any oncological therapy. Factors associated with reduced likelihood of receiving curative treatment included: advanced stage (OR = 0.45; 95% CI = 0.42-0.49), somatic comorbidity (OR = 0.72; 95% CI = 0.63-0.83), age ≥ 80 years (OR = 0.59; 95% CI = 0.55-0.64), performance status = 2 (OR = 0.33; 95% CI = 0.28-0.39) and living alone (OR = 0.79; 95% CI = 0.69-0.90). Results were similar for stage IIIB-IV NSCLC patients, although a statistically significant association was also seen for long distances to the hospital (OR = 0.71; 95% CI = 0.58-0.86).

CONCLUSIONS

Several factors are associated with not receiving guideline-recommended NSCLC treatment with age, performance status, comorbidity and stage being most predictive of no treatment receipt. Efforts should be made to develop support for vulnerable lung cancer patients to improve adherence to optimal first-line therapy.

Research Priorities for Interventions to Address Health Disparities in Lung Nodule Management: An Official American Thoracic Society Research Statement

Background: Lung nodules are common incidental findings, and timely evaluation is critical to ensure diagnosis of localized-stage and potentially curable lung cancers. Rates of guideline-concordant lung nodule evaluation are low, and the risk of delayed evaluation is higher for minoritized groups. Objectives: To summarize the existing evidence, identify knowledge gaps, and prioritize research questions related to interventions to reduce disparities in lung nodule evaluation. Methods: A multidisciplinary committee was convened to review the evidence and identify key knowledge gaps in four domains: 1) research methodology, 2) patient-level interventions, 3) clinician-level interventions, and 4) health system-level interventions. A modified Delphi approach was used to identify research priorities. Results: Key knowledge gaps included 1) a lack of standardized approaches to identify factors associated with lung nodule management disparities, 2) limited data evaluating the role of social determinants of health on disparities in lung nodule management, 3) a lack of certainty regarding the optimal strategy to improve patient-clinician communication and information transmission and/or retention, and 4) a paucity of information on the impact of patient navigators and culturally trained multidisciplinary teams. Conclusions: This statement outlines a research agenda intended to stimulate high-impact studies of interventions to mitigate disparities in lung nodule evaluation. Research questions were prioritized around the following domains: 1) need for methodologic guidelines for conducting research related to disparities in nodule management, 2) evaluating how social determinants of health influence lung nodule evaluation, 3) studying approaches to improve patient-clinician communication, and 4) evaluating the utility of patient navigators and culturally enriched multidisciplinary teams to reduce disparities.

Breast cancer treatment disparities in patients with severe mental illness: A systematic review and meta-analysis

OBJECTIVE

The incidence and mortality rates of breast cancer in individuals with pre-existing severe mental illness (SMI), such as schizophrenia, bipolar disorder, and major depression, are higher than in the general population. Reduced screening is one factor but there is less information on possible barriers to subsequent treatment following diagnosis.

METHODS

We undertook a systematic review and meta-analysis on access to guideline-appropriate care following a diagnosis of breast cancer in people with SMI including the receipt of surgery, endocrine, chemo- or radiotherapy. We searched for full-text articles indexed by PubMed, EMBASE, PsycInfo and CINAHL that compared breast cancer treatment in those with and without pre-existing SMI. Study designs included population-based cohort or case-control studies.

RESULTS

There were 13 studies included in the review, of which 4 contributed adjusted outcomes to the meta-analyses. People with SMI had a reduced likelihood of guideline-appropriate care (RR = 0.83, 95% CI = 0.77-0.90). Meta-analyses were not possible for the other outcomes but in adjusted results from a single study, people with SMI had longer wait-times to receiving guideline-appropriate care. The results for specific outcomes such as surgery, hormone, radio- or chemotherapy were mixed, possibly because results were largely unadjusted for age, comorbidities, or cancer stage.

CONCLUSIONS

People with SMI receive less and/or delayed guideline-appropriate care for breast cancer than the general population. The reasons for this disparity warrant further investigation, as does the extent to which differences in treatment access or quality contribute to excess breast cancer mortality in people with SMI.

Impact of pre-existing mental health disorders on the receipt of guideline recommended cancer treatments: A systematic review

OBJECTIVE

Disparities in cancer outcomes for individuals with pre-existing mental health disorders have already been identified, particularly for cancer screening and mortality. We aimed to systematically review the influence on the time from cancer diagnosis to cancer treatment, treatment adherence, and differences in receipt of guideline recommended cancer treatment.

METHODS

We included international studies published in English from 1 January 1995 to 23 May 2022 by searching MEDLINE, Embase, and APA PsycInfo.

RESULTS

This review identified 29 studies with 27 being published in the past decade. Most studies focused on breast, non-small cell lung and colorectal cancer and were of high or medium quality as assessed by the Newcastle Ottawa Scale. All studies were from high-income countries, and mostly included patients enrolled in national health insurance systems. Five assessed the impact on treatment delay or adherence, and 25 focused on the receipt of guideline recommended treatment. 20/25 studies demonstrated evidence that patients with pre-existing mental health disorders were less likely to receive guideline recommended therapies such as surgery or radiotherapy. In addition, there was a greater likelihood of receiving less intensive or modified treatment including systemic therapy.

CONCLUSIONS

Across different cancer types and treatment modalities there is evidence of a clear disparity in the receipt of guideline recommended cancer treatment for patients with pre-existing mental health disorders. The effect of pre-existing mental health disorders on treatment delay or adherence is under-researched. Future research needs to include low- and middle-income countries as well as qualitative investigations to understand the reasons for disparities in cancer treatment.

How does severe mental illness impact on cancer outcomes in individuals with severe mental illness and cancer? A scoping review of the literature

INTRODUCTION

Individuals living with severe mental illness (SMI) have a reduced life expectancy of approximately 15-20 years compared to the general population^1,2. Individuals with SMI and comorbid cancer have increased cancer related mortality rates compared to the non SMI population. This scoping review examines the current evidence in relation to the impact on cancer outcomes where individuals have a pre-existing SMI.

METHODS

Scopus, PsychINFO, PubMed, PsycArticles and the Cochrane Library were searched for peer reviewed research articles, published in English language between 2001 and 2021. Initial title and abstract screening, followed by full text screening sourced articles reporting on the impact of SMI and cancer on: stage at diagnosis, survival, treatment access or quality of life. Articles were quality appraised, and data were extracted and summarised.

RESULTS

The search yielded 1226 articles, 27 met the inclusion criteria. The search yielded no articles that met the inclusion criteria that were from the perspective of the service user or that were focused on the impact of SMI and cancer quality of life. Three themes were developed following analysis: Cancer related mortality, stage at diagnosis, and access to stage appropriate treatment.

DISCUSSION

The collective study of populations with comorbid SMI and cancer is complex and challenging without a large-scale cohort study. The studies yielded through this scoping review were heterogenous and often study multiple diagnoses of SMI and cancer. Collectively these indicate that cancer related mortality is increased in the population of individuals with pre-existing SMI and the SMI population are more likely to have an increased likelihood of metastatic disease at diagnosis and less likely to receive stage appropriate treatment.

CONCLUSIONS

Individuals with pre-existing SMI and cancer have increased cancer specific mortality. Comorbid SMI and cancer is complex, and individuals with SMI and cancer are less likely to receive optimal treatments, experience increased interruptions and delays to treatment.

Study protocol for a randomized trial of bridge: Person-centered collaborative care for serious mental illness and cancer

BACKGROUND

Individuals with serious mental illness (SMI) experience inequities in cancer care that contribute to increased cancer mortality. Involving mental health at the time of cancer diagnosis may improve cancer care delivery for patients with SMI yet access to care remains challenging. Collaborative care is a promising approach to integrate mental health and cancer care that has not yet been studied in this marginalized population.

METHODS/DESIGN

We describe a 24-week, two-arm, single-site randomized trial of person-centered collaborative care (Bridge) for patients with SMI (schizophrenia, bipolar disorder, or major depression with psychiatric hospitalization) and their caregivers. 120 patients are randomized 1:1 to Bridge or Enhanced Usual Care (EUC) along with their caregivers. Researchers proactively identify individuals with SMI and a new breast, lung, gastrointestinal, or head and neck cancer that can be treated with curative intent. EUC includes informing oncologists about the patient's psychiatric diagnosis, notifying patients about available psychosocial services, and tracking patient and caregiver outcomes. Bridge includes a proactive assessment by psychiatry and social work, a person-centered, team approach including collaboration between mental health and oncology, and increased access to evidence-based psycho-oncology care. The primary outcome is cancer care disruptions evaluated by a blinded panel of oncologists. Secondary outcomes include patient and caregiver-reported outcomes and healthcare utilization. Barriers to Bridge implementation and dissemination are assessed using mixed methods.

DISCUSSION

This trial will inform efforts to systematically identify individuals with SMI and cancer and generate the first experimental evidence for the impact of person-centered collaborative care on cancer care for this underserved population.

Cancer incidence and stage at diagnosis among people with psychotic disorders: Systematic review and meta-analysis

Research regarding the incidence of cancer among people with psychotic disorders relative to the general population is equivocal, although the evidence suggests that they have more advanced stage cancer at diagnosis. We conducted a systematic review and meta-analysis to examine the incidence and stage at diagnosis of cancer among people with, relative to those without, psychotic disorders. We searched the MEDLINE, EMBASE, PsycINFO, and CINAHL databases. Articles were included if they reported the incidence and/or stage at diagnosis of cancer in people with psychotic disorders. Random effects meta-analyses were used to determine risk of cancer and odds of advanced stage cancer at diagnosis in people with psychosis, relative to those without psychotic disorders. A total of 40 articles were included in the review, of which, 31 were included in the meta-analyses. The pooled age-adjusted risk ratio for all cancers in people with psychotic disorders was 1.08 (95% CI: 1.01-1.15), relative to those without psychotic disorders, with significant heterogeneity by cancer site. People with psychotic disorders had a higher incidence of breast, oesophageal, colorectal, testicular, uterine, and cervical cancer, and a lower incidence of skin, prostate, and thyroid cancer. People with psychotic disorders also had 22% higher (95% CI: 2-46%) odds of metastases at diagnosis, compared to those without psychotic disorders. Our systematic review found a significant difference in overall cancer incidence among people diagnosed with psychotic disorders and people with psychotic disorders were more likely to present with advanced stage cancer at diagnosis. This finding may reflect a need for improved access to and uptake of cancer screening for patients diagnosed with psychotic disorders.

Health Care Disparities in Radiology-A Review of the Current Literature

INTRODUCTION

Health care disparities exist in all medical specialties, including radiology. Raising awareness of established health care disparities is a critical component of radiology's efforts to mitigate disparities. Our primary objective is to perform a comprehensive review of the last 10 years of literature pertaining to disparities in radiology care. Our secondary objective is to raise awareness of disparities in radiology.

METHODS

We reviewed English-language medicine and health services literature from the past 10 years (2010-2020) for research that described disparities in any aspect of radiologic imaging using radiology search terms and key words for disparities in OVID. Relevant studies were identified with adherence to the guidelines set forth by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

RESULTS

The search yielded a total 1,890 articles. We reviewed the citations and abstracts with the initial search yielding 1,890 articles (without duplicates). Of these, 1,776 were excluded based on the criteria set forth in the methods. The remaining unique 114 articles were included for qualitative synthesis.

DISCUSSION

We hope this article increases awareness and inspires action to address disparities and encourages research that further investigates previously identified disparities and explores not-yet-identified disparities.

OUP accepted manuscript

We define cancer equity as all people having as the same opportunity for cancer prevention, treatment, and survivorship care. However, marginalized populations continue to experience avoidable and unjust disparities in cancer care, access to clinical trials, and cancer survival. Racial and ethnic minorities, and individuals with low socioeconomic status, Medicaid insurance, limited health literacy, disabilities, and mental health disorders are more likely to experience delays to cancer diagnosis and less likely to receive guideline-concordant cancer care. These disparities are impacted by the social determinants of health including structural discrimination, racism, poverty, and inequities in access to healthcare and clinical trials. There is an urgent need to develop and adapt evidence-based interventions in collaboration with community partners that have potential to address the social determinants of health and build capacity for cancer care for underserved populations. We established the Virtual Equity Hub by developing a collaborative network connecting a comprehensive cancer center, academic safety net hospital, and community health centers and affiliates. The Virtual Equity Hub utilizes a virtual tumor board, an evidence-based approach that increases access to multi-specialty cancer care and oncology subspecialty expertise. We adapted the tumor board model by engaging person-centered teams of multi-disciplinary specialists across health systems, addressing the social determinants of health, and applying community-based research principles with a focus on populations with poor cancer survival. The virtual tumor board included monthly videoconferences, case discussion, sharing of expertise, and a focus on addressing barriers to care and trial participation. Specifically, we piloted virtual tumor boards for breast oncology, neuro-oncology, and individuals with cancer and serious mental illness. The Virtual Equity Hub demonstrated promise at building capacity for clinicians to care for patients with complex needs and addressing barriers to care. Research is needed to measure the impact, reach, and sustainability of virtual equity models for patients with cancer.

Palliative and high-intensity end-of-life care in schizophrenia patients with lung cancer: results from a French national population-based study

Schizophrenia is marked by inequities in cancer treatment and associated with high smoking rates. Lung cancer patients with schizophrenia may thus be at risk of receiving poorer end-of-life care compared to those without mental disorder. The objective was to compare end-of-life care delivered to patients with schizophrenia and lung cancer with patients without severe mental disorder. This population-based cohort study included all patients aged 15 and older who died from their terminal lung cancer in hospital in France (2014-2016). Schizophrenia patients and controls without severe mental disorder were selected and indicators of palliative care and high-intensity end-of-life care were compared. Multivariable generalized log-linear models were performed, adjusted for sex, age, year of death, social deprivation, time between cancer diagnosis and death, metastases, comorbidity, smoking addiction and hospital category. The analysis included 633 schizophrenia patients and 66,469 controls. The schizophrenia patients died 6 years earlier, had almost twice more frequently smoking addiction (38.1%), had more frequently chronic pulmonary disease (32.5%) and a shorter duration from cancer diagnosis to death. In multivariate analysis, they were found to have more and earlier palliative care (adjusted Odds Ratio 1.27 [1.03;1.56]; p = 0.04), and less high-intensity end-of-life care (e.g., chemotherapy 0.53 [0.41;0.70]; p < 0.0001; surgery 0.73 [0.59;0.90]; p < 0.01) than controls. Although the use and/or continuation of high-intensity end-of-life care is less important in schizophrenia patients with lung cancer, some findings suggest a loss of chance. Future studies should explore the expectations of patients with schizophrenia and lung cancer to define the optimal end-of-life care.

Associations between comorbidities and advanced stage diagnosis of lung, breast, colorectal, and prostate cancer: A systematic review and meta-analysis

Comorbidities and advanced stage diagnosis (ASD) are both associated with poorer cancer outcomes, but the association between comorbidities and ASD is poorly understood. We summarized epidemiological evidence on the association between comorbidities and ASD of selected cancers in a systematic review and meta-analysis. We searched PubMed and Web of Science databases up to June 3rd, 2021 for studies assessing the association between comorbidities and ASD of lung, breast, colorectal, or prostate cancer. Summary odds ratios (ORs) and 95% confidence intervals (95%CIs) were calculated using random-effects models. Also, potential variations in the associations between comorbidities and ASD by cancer type were investigated using random-effects meta-regression. Thirty-seven studies were included in this review, including 8,069,397 lung, breast, colorectal, and prostate cancer patients overall. The Charlson comorbidity index score was positively associated with ASD (stages III-IV) of breast cancer but was inversely associated with ASD of lung cancer (p_interaction = 0.004). Regarding specific comorbidities, diabetes was positively associated with ASD (OR = 1.17, 95%CI = 1.09-1.26), whereas myocardial infarction was inversely associated with ASD (OR = 0.84, 95%CI = 0.75-0.95). The association between renal disease and ASD differed by cancer type (p_interaction < 0.001). A positive association was found with prostate cancer (OR = 2.02, 95%CI = 1.58-2.59) and an inverse association with colorectal cancer (OR = 0.84, 95%CI = 0.70-1.00). In summary, certain comorbidities (e.g., diabetes) may be positively associated with ASD of several cancer types. It needs to be clarified whether closer monitoring for early cancer signs or screening in these patients is reasonable, considering the problem of over-diagnosis particularly relevant in patients with short remaining life expectancy such as those with comorbidities. Also, evaluation of the cost-benefit relationship of cancer screening according to the type and severity of comorbidity (rather than summary scores) may be beneficial for personalized cancer screening in populations with chronic diseases.

Mortality from cancer in people with severe mental disorders in Emilia Romagna Region, Italy

Objective

To examine cancer‐related mortality in patients with severe mental disorders (SMI) in the Emilia Romagna (ER) Region, Northern Italy, during the period 2008–2017 and compare it with the regional population.

Methods

We used the ER Regional Mental Health Registry identifying all patients aged ≥18 years who had received an ICD‐9CM system diagnosis of SMI (i.e., schizophrenia or other functional psychosis, mania, or bipolar affective disorders) during a 10‐year period (2008–2017). Information on deaths (date and causes of death) were retrieved through the Regional Cause of Death Registry. Comparisons were made with the deaths and cause of deaths of the regional population over the same period.

Results

Amongst 12,385 patients suffering from SMI (64.1% schizophrenia spectrum and 36.9% bipolar spectrum disorders), 24% (range 21%–29%) died of cancer. In comparison with the general regional population, the mortality for cancer was about 50% higher among patients with SMI, irrespective if affected by schizophrenia or bipolar disorders. As for the site‐specific cancers, significant excesses were reported for stomach, central nervous system, respiratory, and pancreas cancer with a variability according to psychiatric diagnosis and gender.

Conclusions

Patients suffering from SMI had higher mortality risk than the regional population with some differences according to cancer type, gender, and psychiatric diagnosis. Proper cancer preventive and treatment interventions, including more effective risk modification strategies (e.g., smoking cessation, dietary habits) and screening for cancer, should be part of the agenda of all mental health departments in conjunction with other health care organizations, including psycho‐oncology.

Feasibility and Acceptability of a Collaborative Lung Cancer Screening Educational Intervention Tailored for Individuals With Serious Mental Illness

PURPOSE

Individuals with serious mental illness (SMI) experience disparities in lung cancer mortality. Using a two-phase, mixed-methods approach, we developed a person-centered lung cancer screening (LCS) educational intervention (phase 1) for individuals with SMI (schizophrenia and bipolar disorder) and evaluated acceptability, feasibility, and changes in attitudes toward LCS (phase 2).

METHODS

Phase 1: We conducted three focus groups with mental health, primary care, and radiology clinicians and utilized rapid qualitative analysis to adapt the LCS intervention (LCS walk-through video and smoking cessation handouts) tailored for individuals with SMI. Phase 2: We enrolled LCS-eligible patients with SMI (n = 15) and assessed the feasibility (>50% enrollment; >75% completion) and acceptability (>75% overall satisfaction) of an LCS educational intervention delivered by a radiologist and a mental health clinician at a community mental health clinic. We explored changes in participant attitudes about lung cancer, LCS, and smoking before and after the intervention.

RESULTS

Phase 1: Focus groups with primary care (n = 5), radiologists (n = 9), and mental health clinicians (n = 6) recommended person-centered language and adapting a video demonstrating the process of LCS to address concerns specific to SMI, including paranoia and concrete thinking. Phase 2: Fifty percent (15 of 30) of eligible patients enrolled in the LCS intervention, 100% (15 of 15) completed the intervention, and 93% (14 of 15) were satisfied with the intervention. Participants reported a significantly greater worry about developing lung cancer postintervention, but there were no other significant differences.

CONCLUSIONS

Radiologists can partner with primary care and community mental health clinics to lead LCS equity among individuals with SMI.

Association of Mental Health Treatment With Outcomes for US Veterans Diagnosed With Non-Small Cell Lung Cancer

Importance

Preexisting mental health disorders (MHDs) are associated with increased mortality in people diagnosed with cancer, yet few data exist on the efficacy of interventions to mitigate this disparity.

Objective

To evaluate the association of participation in mental health treatment programs (MHTPs), housing support programs, or employment support programs with stage at cancer diagnosis, receipt of stage-appropriate treatment, and mortality among patients with a preexisting MHD.

Design, Setting, and Participants

This retrospective, population-based cohort study included 55 315 veterans in the Veterans Affairs Central Cancer Registry (VACCR) who had newly diagnosed non-small cell lung cancer (NSCLC) from September 30, 2000, to December 31, 2011. Data were analyzed from January 15, 2017, to March 17, 2020.

Exposures

Mental health disorders, including schizophrenia, bipolar disorder, depressive disorder, posttraumatic stress disorder, and substance use disorder.

Main Outcomes and Measures

Stage at cancer diagnosis, receipt of stage-appropriate cancer treatment, all-cause mortality, and lung cancer-specific mortality.

Results

Of 55 315 veterans with a new diagnosis of NSCLC included in the analysis (98.1% men; mean [SD] age, 68.1 [9.8] years), 18 229 had a preexisting MHD, among whom participation in MHTPs was associated with a lower likelihood of being diagnosed in a late stage (odds ratio [OR], 0.62; 95% CI, 0.58-0.66; P < .001), a higher likelihood of receiving stage-appropriate treatment (OR, 1.55; 95% CI, 1.26-1.89; P < .001), lower all-cause mortality (adjusted hazard ratio [AHR], 0.74; 95% CI, 0.72-0.77; P < .001), and lower lung cancer-specific mortality (AHR, 0.77; 95% CI, 0.74-0.80; P < .001). Likewise, participation in housing and employment support programs was associated with similar improvements in all outcomes described above.

Conclusions and Relevance

In veterans with preexisting MHDs diagnosed with NSCLC, participation in MHTPs and housing and employment support programs was associated with improved lung cancer-related outcomes. This study might be the first to demonstrate significant improvement in cancer mortality for patients with MHDs who participate in MHTPs, housing support programs, or employment support programs. This work supports substantial literature that investment in mental health and social needs can improve health outcomes and highlights the importance of further research to identify, evaluate, and implement interventions to improve outcomes for patients with MHDs who are diagnosed with cancer.

Barriers to Somatic Health Care for Persons With Severe Mental Illness in Belgium: A Qualitative Study of Patients' and Healthcare Professionals' Perspectives

BACKGROUND

A huge and still growing mortality gap between people with severe mental illness (SMI) and the general population exists. Physical illnesses, mainly cardiovascular diseases, substantially contribute to the high mortality rates in patients with SMI. Disparities in somatic health care access, utilisation, and provision contribute to these poor physical health outcomes.

METHODS

A qualitative study, using semi-structured interviews, was set up to explore SMI patients' and healthcare professionals' perspectives on somatic health care in different psychiatric settings of the three Belgian regions (Flanders, Brussels, Wallonia). Interviews were digitally recorded and transcribed prior to qualitative inductive thematic analysis, using Nvivo software. The COnsolidated criteria for REporting Qualitative research (COREQ) were used for reporting methods and findings.

RESULTS

Collaboration and information flows between psychiatric healthcare professionals, non-psychiatric healthcare professionals, and persons with SMI were troublesome. This seemed to be mainly due to stigma and prejudice and challenging communication and data transfer. Lack of sufficient training and experience to identify and treat somatic health problems in people with SMI (for psychiatrists and psychiatric nurses) and lack of psychiatric knowledge and feeling or sensitivity for psychiatric patients (for non-psychiatric healthcare professionals) further complicated adequate somatic health care. Finally, optimal somatic follow-up of patients with SMI was hampered by organisational problems (unavailability of equipment, unadapted infrastructure, understaffing, hospital pharmacy issues, and insufficient health promotion/lifestyle interventions), patient-related issues (unawareness of physical problems, non-adherence, need for accompaniment) and financial barriers.

CONCLUSION

There is an urgent need for integrated somatic and mental healthcare systems and a cultural change. Psychiatrists and primary care providers continue to consider the mental and physical health of their patients as mutually exclusive responsibilities due to a lack of sufficient training and experience, poor or absent liaison links, time constraints and organisational and financial barriers. Modifying these aspects will improve the quality of somatic health care for these vulnerable patients.

Performance in Practice: Practice Assessment Tool for the Care of Patients With Schizophrenia

Schizophrenia is associated with significant health, social, occupational, and economic burdens, including increased mortality. Despite extensive and robust research on the treatment of individuals with schizophrenia, many individuals with the illness do not currently receive evidence-based pharmacological and nonpharmacological treatments. The American Psychiatric Association Practice Guideline for the Treatment of Patients With Schizophrenia, Third Edition, aims to enhance knowledge and increase the appropriate use of interventions for schizophrenia, thereby improving the quality of care and treatment outcomes. To this end, this evidence-based Performance in Practice tool can facilitate the implementation of a systematic approach to practice improvement for the care of individuals with schizophrenia. This practice assessment activity can also be used in partial fulfillment of Continuing Medical Education and Maintenance of Certification, part IV, requirements, which can also satisfy requirements for the Centers for Medicare & Medicaid Services Merit-based Incentive Payment System program.

The effect of a severe psychiatric illness on colorectal cancer treatment and survival: A population-based retrospective cohort study

OBJECTIVES

To identify inequalities in cancer survival rates for patients with a history of severe psychiatric illness (SPI) compared to those with no history of mental illness and explore differences in the provision of recommended cancer treatment as a potential explanation.

DESIGN

Population-based retrospective cohort study using linked cancer registry and administrative data at ICES.

SETTING

The universal healthcare system in Ontario, Canada.

PARTICIPANTS

Colorectal cancer (CRC) patients diagnosed between April 1st, 2007 and December 31st, 2012. SPI history (schizophrenia, schizoaffective disorders, other psychotic disorders, bipolar disorders or major depressive disorders) was determined using hospitalization, emergency department, and psychiatrist visit data and categorized as 'no history of mental illness, 'outpatient SPI history', and 'inpatient SPI history'.

MAIN OUTCOME MEASURES

Cancer-specific survival, non-receipt of surgical resection, and non-receipt of adjuvant chemotherapy or radiation.

RESULTS

24,507 CRC patients were included; 482 (2.0%) had an outpatient SPI history and 258 (1.0%) had an inpatient SPI history. Individuals with an SPI history had significantly lower survival rates and were significantly less likely to receive guideline recommended treatment than CRC patients with no history of mental illness. The adjusted HR for cancer-specific death was 1.69 times higher for individuals with an inpatient SPI (95% CI 1.36-2.09) and 1.24 times higher for individuals with an outpatient SPI history (95% CI 1.04-1.48). Stage II and III CRC patients with an inpatient SPI history were 2.15 times less likely (95% CI 1.07-4.33) to receive potentially curative surgical resection and 2.07 times less likely (95% CI 1.72-2.50) to receive adjuvant radiation or chemotherapy. These findings were consistent across multiple sensitivity analyses.

CONCLUSIONS

Individuals with an SPI history experience inequalities in colorectal cancer care and survival within a universal healthcare system. Increasing advocacy and the availability of resources to support individuals with an SPI within the cancer system are warranted to reduce the potential for unnecessary harm.

Improving Lung Cancer Screening Access for Individuals With Serious Mental Illness

Lung cancer continues to be the leading cause of cancer mortality in the United States across all races and ethnicities, but it does not affect everyone equally. Individuals with serious mental illness (SMI), including schizophrenia and bipolar disorder, experience two to four times greater lung cancer mortality in part due to high rates of smoking, delays in cancer diagnosis, and inequities in cancer treatment. Additionally, adults with SMI experience patient, clinician, and health care system-level barriers to accessing cancer screening, such as cognitive deficits that impact understanding of cancer risk, higher rates of poverty and social isolation, patient-provider communication challenges, decreased access to tobacco cessation, and the fragmentation of primary care and mental health care. Despite the proven benefits and mandated coverage by public and private payers, lung cancer screening participation rates remain low among eligible patients, below 4% a year. Given disparities in other cancer screening modalities, these rates are likely to be even lower among individuals with SMI. This article provides a brief overview of current challenges in lung cancer screening and describes a pilot collaboration between radiology and psychiatry that has potential to improve access to lung cancer screening for individuals with serious mental illness.

Mortality of site-specific cancer in patients with schizophrenia: a systematic review and meta-analysis

BACKGROUND

Numerous studies have reported contradicting results on the relationship between cancer mortality and schizophrenia. Our aim is to quantify the mortality rate of common site-specific cancers among patients with schizophrenia and to synthesize the available research evidence.

METHODS

We performed a systemic search of the PubMed, EMBASE and Web of Science databases. Studies reporting the mortality rate of different cancer in patients with schizophrenia were included. A random-effects model was applied to calculate the pooled relative risks (RRs) with 95% confidence intervals (95%CIs).

RESULTS

Seven studies consisting of 1,162,971 participants with schizophrenia were included in this meta-analysis. Data regarding mortality risk of breast, colon, lung and prostate cancer among schizophrenia patients were subjected to quantitative analysis. Pooled results showed significant increases in mortality risk of breast cancer (RR = 1.97, 95%CI 1.38-2.83), lung cancer (RR = 1.93, 95%CI 1.46-2.54) and colon cancer (RR = 1.69, 95%CI 1.60-1.80) in patients with schizophrenia compared with those in the general population or control group. The mortality risk of prostate cancer increased in male patients, although no significant difference was detected (RR = 1.58, 95% CI 0.79-3.15). Increased risks of mortality from lung and colon cancer were observed in female patients (RR = 2.49, 95%CI 2.40-2.59 and RR = 2.42, 95%CI 1.39-4.22, respectively) and elevated risks of mortality from lung and colon cancer in male patients (RR = 2.40, 95%CI 2.30-2.50 and RR = 1.90, 95%CI 1.71-2.11, respectively) were detected.

CONCLUSIONS

Individuals with schizophrenia have a significantly high risk of mortality from breast, colon, and lung cancer.

Stage at diagnosis and survival in patients with cancer and a pre-existing mental illness: a meta-analysis

INTRODUCTION

Individuals with a pre-existing mental illness, especially those experiencing reduced social, occupational and functional capacity, are at risk for cancer care disparities. However, uncertainty surrounding the effect of a mental illness on cancer outcomes exists.

METHODS

We conducted a systematic review and meta-analysis of observational studies using MEDLINE and PubMed from 1 January 2005 to 1 November 2018. Two reviewers evaluated citations for inclusion. Advanced stage was defined as regional, metastatic or according to a classification system. Cancer survival was defined as time survived from cancer diagnosis. Pooled ORs and HRs were presented. The Newcastle-Ottawa bias risk assessment scale was used. Random-effects models used the Mantel-Haenszel approach and the generic inverse variance method. Heterogeneity assessment was performed using I².

RESULTS

2381 citations were identified; 28 studies were included and 24 contributed to the meta-analysis. Many demonstrated methodological flaws, limiting interpretation and contributing to significant heterogeneity. Data source selection, definitions of a mental illness, outcomes and their measurement, and overadjustment for causal pathway variables influenced effect sizes. Pooled analyses suggested individuals with a pre-existing mental disorder have a higher odds of advanced stage cancer at diagnosis and are at risk of worse cancer survival. Individuals with more severe mental illness, such as schizophrenia, are at a greater risk for cancer disparities.

DISCUSSION

This review identified critical gaps in research investigating cancer stage at diagnosis and survival for individuals with pre-existing mental illness. High-quality research is necessary to support quality improvement for the care of psychiatric patients and their families during and following a cancer diagnosis.

Lung Cancer Screening Eligibility, Risk Perceptions, and Clinician Delivery of Tobacco Cessation Among Patients With Schizophrenia

OBJECTIVE

Individuals with schizophrenia experience increased lung cancer mortality and decreased access to cancer screening and tobacco cessation treatment. To promote screening among individuals with schizophrenia, it is necessary to investigate the proportion who meet screening criteria and examine smoking behaviors, cancer risk perception, and receipt of tobacco cessation interventions from psychiatry and primary care.

METHODS

The authors performed a cross-sectional survey and medical record review with 112 adults with schizophrenia treated with clozapine in a community mental health clinic (CMHC).

RESULTS

Among older participants (ages 55-77 years) with schizophrenia, 34% met the criteria for lung screening on the basis of smoking history (heavy current or former smokers), and more than half believed they had a low risk of developing lung cancer. Of all participants, 88% had visited their primary care provider (PCP) in the past year; PCPs represented 35 different practices. Only one in three current smokers reported that their PCP or psychiatrist assisted them in obtaining medications for tobacco cessation.

CONCLUSIONS

Given smoking history, many older adults with schizophrenia have potential to benefit from lung screening, yet most older participants underestimated their lung cancer risk. Although participants regularly accessed care, PCP and psychiatric visits may be missed opportunities to engage patients with schizophrenia in tobacco cessation and decrease preventable premature mortality. Embedding interventions in a CMHC, a centralized access point of care delivery for patients with schizophrenia, may have unique potential to increase uptake of cancer screening and tobacco cessation interventions.

Bridge: Person-Centered Collaborative Care for Patients with Serious Mental Illness and Cancer

BACKGROUND

Individuals with serious mental illness (SMI) experience increased cancer mortality due to inequities in cancer treatment. Psychiatric care at cancer diagnosis may improve care delivery, yet models for integrating psychiatry and cancer care are lacking. We assessed the feasibility and acceptability of a person-centered collaborative care trial for SMI and cancer.

SUBJECTS, MATERIALS, AND METHODS

We developed the Bridge intervention for patients with SMI (schizophrenia, bipolar disorder, and severe major depression) and cancer. Bridge includes proactive identification of SMI, person-centered care from a psychiatrist and case manager, and collaboration with oncology. We conducted a 12-week, single-group trial in patients with SMI and a new breast, gastrointestinal, lung, or head/neck cancer. We assessed the feasibility of patient identification, enrollment and study completion; evaluated acceptability and perceived benefit with exit interviews with patients, caregivers, and oncology clinicians; and examined change in psychiatric symptoms with the Brief Psychiatric Rating Scale (BPRS).

RESULTS

From November 2015 to April 2016, 30/33 eligible patients (90.9%) enrolled, and 25/29 (86.2%) completed assessments at all timepoints, meeting feasibility criteria. Of 24 patients, 23 (95.8%) found meeting with the psychiatrist helpful; 16/19 caregivers (84.2%) shared that Bridge addressed key caregiving challenges. Oncology clinicians evaluated Bridge as "very" or "most" useful for 94.3% of patients. Exit interviews with all participant groups suggested that Bridge fostered patient-clinician trust, increased access to psychiatric treatment, and enabled patients to initiate and complete cancer treatment. Psychiatric symptoms on the BPRS improved from baseline to 12 weeks.

CONCLUSION

Bridge is a feasible and acceptable care delivery model for patients with SMI, their caregivers, and oncology clinicians. Randomized trials are warranted to assess the efficacy of improving cancer outcomes in this underserved population.

IMPLICATIONS FOR PRACTICE

Serious mental illness affects 13 million U.S. adults who experience increased cancer mortality. To improve outcomes, new models of integrated oncology and mental health care are urgently needed. This study found that it was feasible to identify, enroll, and retain patients with serious mental illness and a new cancer in a trial of integrated mental health and cancer care (Bridge). Patients, caregivers, and oncologists reported that Bridge facilitated the initiation and completion of cancer care. Randomized trials are warranted to investigate the impact on cancer outcomes. Trial procedures may inform consent, engagement, and trial retention for patients with mental illness.

Impact of severe mental illness on cancer stage at diagnosis and subsequent mortality: A population-based register study

BACKGROUND

Excess mortality in individuals with severe mental illness (SMI) is often explained by physical comorbidity and suboptimal healthcare. Cancer is a prevalent cause of death, and tumour stage at diagnosis is a strong predictor of mortality. We aimed to study cancer incidence, disease stage at diagnosis and subsequent mortality in individuals with SMI compared to individuals without SMI.

METHODS

The entire Danish population was followed in 1978-2013 using nationwide registries. Cancer incidence and subsequent mortality stratified by disease stage were compared in individuals with and without SMI. Cox regression was used to estimate incidence rate ratios (IRR) and mortality rate ratios (MRR). Cancer was examined overall and grouped by major aetiological factors.

RESULTS

The overall cancer incidence rate was lower in males with SMI than in males without SMI; IRR = 0.89 (95% CI: 0.85-0.94), but rates were similar in females with SMI and without SMI; IRR = 1.03 (95% CI: 0.99-1.07). The overall mortality rate was higher in individuals with SMI than those without; MRR = 1.56 (95% CI: 1.48-1.64) for males and MRR = 1.49 (95% CI: 1.43-1.56) for females. Incidence rates and mortality rates showed similar estimates when stratified by tumour stage and aetiology.

CONCLUSIONS

We found lower cancer incidence in males with SMI compared to males without SMI and similar incidence in the two groups of women. Higher subsequent mortality was found in both sexes with SMI. The excess mortality was not explained by more advanced stages of cancer; future studies should evaluate the effect of cancer treatment and rehabilitation.

Mortality in people with psychotic disorders in Finland: A population-based 13-year follow-up study

OBJECTIVES

We conducted a population based study aiming at finding predictors of mortality in psychotic disorders and evaluating the extent to which sociodemographic, lifestyle and health-related factors explain the excess mortality.

METHODS

In a nationally representative sample of Finns aged 30-70years (n=5642), psychotic disorders were diagnosed using structured interviews and medical records in 2000-2001. Information on mortality and causes of death was obtained of those who died by the end of year 2013. Cox proportional hazards models were used to investigate the mortality risk.

RESULTS

No people with affective psychoses (n=36) died during the follow-up, thus the analysis was restricted to non-affective psychotic disorders (NAP) (n=106). Adjusting for age and sex, NAP was statistically significantly associated with all-cause mortality (hazard ratio (HR) 2.99, 95% CI 2.03-4.41) and natural-cause mortality (HR 2.81, 95% CI 1.85-4.28). After adjusting for sociodemographic factors, health status, inflammation and smoking, the HR dropped to 2.11 (95% CI 1.10-4.05) for all-cause and to 1.98 (95% CI 0.94-4.16) for natural-cause mortality. Within the NAP group, antipsychotic use at baseline was associated with reduced HR for natural-cause mortality (HR 0.25, 95% CI 0.07-0.96), and smoking with increased HR (HR 3.54, 95% CI 1.07-11.69).

CONCLUSIONS

The elevated mortality risk in people with NAP is only partly explained by socioeconomic factors, lifestyle, cardio-metabolic comorbidities and inflammation. Smoking cessation should be prioritized in treatment of psychotic disorders. More research is needed on the quality of treatment of somatic diseases in people with psychotic disorders.

Predictors of Disruptions in Breast Cancer Care for Individuals with Schizophrenia

BACKGROUND

Patients with schizophrenia experience markedly increased breast cancer mortality, yet reasons for this disparity are poorly understood. We sought to characterize disruptions in breast cancer care for patients with schizophrenia and identify modifiable predictors of those disruptions.

MATERIALS AND METHODS

We performed a medical record review of 95 patients with schizophrenia and breast cancer treated at an academic cancer center between 1993 and 2015. We defined cancer care disruptions as processes that interfere with guideline-concordant cancer care, including delays to diagnosis or treatment, deviations from stage-appropriate treatment, and interruptions in treatment. We hypothesized that lack of psychiatric treatment at cancer diagnosis would be associated with care disruptions.

RESULTS

Half of patients with schizophrenia experienced at least one breast cancer care disruption. Deviations in stage-appropriate treatment were associated with breast cancer recurrence at 5 years (p = .045). Patients without a documented psychiatrist experienced more delays (p = .016), without documented antipsychotic medication experienced more deviations (p = .007), and with psychiatric hospitalizations after cancer diagnosis experienced more interruptions (p < .0001). Independent of stage, age, and documented primary care physician, lack of documented antipsychotic medication (odds ratio [OR] = 4.97, 95% confidence interval [CI] = 1.90, 12.98) and psychiatric care (OR = 4.56, 95% CI = 1.37, 15.15) predicted cancer care disruptions.

CONCLUSION

Disruptions in breast cancer care are common for patients with schizophrenia and are associated with adverse outcomes, including cancer recurrence. Access to psychiatric treatment at cancer diagnosis may protect against critical disruptions in cancer care for this underserved population.

IMPLICATIONS FOR PRACTICE

Disruptions in breast cancer care are common for patients with schizophrenia, yet access to mental health treatment is rarely integrated into cancer care. When oncologists documented a treating psychiatrist and antipsychotic medication, patients had fewer disruptions in breast cancer care after adjusting for age, cancer stage, and access to primary care. Addressing psychiatric comorbidity at breast cancer diagnosis may increase the likelihood that patients with schizophrenia receive timely, stage-appropriate cancer treatment. Comanagement of schizophrenia and breast cancer at cancer diagnosis may be one key strategy to decrease inequities in cancer treatment and improve cancer survival in this underserved population.

On the Receiving End of Autonomy and Law

It is well-recognized that mental illness is associated with a higher case fatality rate from cancer, although the incidence of cancer is no greater than in the general population. This narrative focuses on the efforts of a multidisciplinary team to guide a patient, who was experiencing psychotic episodes, through chemotherapy while staying within the limits of the law.

Medical Co-morbidities Among Patients with Severe Mental Illnesses in a Community Health Facility in Nigeria

To examine prevalence of medical comorbidity (MCM) in schizophrenia (n = 1310) and in bipolar disorder (n = 1307) and the association of high burden of MCM (≥3 MCM) with duration of untreated illness, number of episodes, functioning, poly-medication and lifetime hospitalization for the mental disorder. Participants were recruited from a private psychiatric facility in Ibadan, Nigeria between 2004 and 2013 and enquiry made about the lifetime occurrence of 20 common chronic diseases including common tropical diseases. Psychiatric diagnosis was made using the Structured Clinical Interview for DSM IV Axis I disorder (SCID). Except for nutritional anemia, dermatitis and intestinal Helminthiasis, patients with schizophrenia were not at higher odds of reporting MCM than those with bipolar disorder. DUI ≥2 years, episodes of illness ≥3, being on multiple neuroleptics and history of previous hospitalization were significantly associated with high burden of MCM in schizophrenia and episodes of illness ≥3, reduced functioning and history of previous hospitalization with bipolar disorder. Schizophrenia and bipolar disorder are associated with high rates of medical comorbidity. Treatment of this medical comorbidity is essential in order to improve the outcomes for patients with bipolar disorder and schizophrenia.

Cancer mortality in patients with schizophrenia: systematic review and meta-analysis

BackgroundPrevious studies have reported conflicting results on the association between schizophrenia and cancer mortality.AimsTo summarise available evidence and quantify the association between schizophrenia and cancer mortality using meta-analysis.MethodWe systematically searched literature in the PubMed and Embase databases. Risk estimates and 95% confidence intervals reported in individual studies were pooled using the DerSimonian-Laird random-effects model.ResultsWe included 19 studies in the meta-analysis. Among them, 15 studies reported standardised mortality ratios (SMRs) comparing patients with schizophrenia with the general population, and the pooled SMR was 1.40 (95% CI 1.29-1.52, P < 0.001). The other four studies reported hazard ratios (HRs) comparing individuals with schizophrenia with those without schizophrenia; the pooled HR was 1.51 (95% CI 1.13-2.03, P = 0.006).ConclusionsPatients with schizophrenia are at a significantly increased risk of cancer mortality compared with the general population or individuals without schizophrenia.

Cancer in patients with schizophrenia: What is the next step?

People with schizophrenia, who constitute approximately 0.3-1% of the general population, have a nearly 20% shorter life expectancy than the general population. The incidence of varied types of cancers in patients with schizophrenia is controversial. The majority of previous research has demonstrated that patients who have schizophrenia and cancer have early mortality compared to the general population with cancer. The causes of early mortality in patients with schizophrenia and cancer might be attributed to a lower cancer screening rate and lack of effective treatment, including: (i) patient factors, such as poor lifestyle, passive attitude toward treatment, or comorbidity; (ii) physician factors, such as physician bias, which may decrease the delivery of care for individuals with mental disorders; and (iii) hospital administration factors, such as stigma and discrimination. Additional studies on patients with schizophrenia and cancer are warranted and should include the following: a comprehensive review of previous studies; a focus on differentiating the specific types of cancer; and methods for improvement. To decrease the early mortality of patients with schizophrenia, the following measures are proposed: (i) enhance early detection and early treatment, such as increasing the cancer screening rate for patients with schizophrenia; (ii) provide effective, timely treatment and rehabilitation; (iii) improve patients' psychiatric symptoms and cognitive impairment; (iv) promote healthy behavior in the general population and emphasize healthy lifestyles in vulnerable populations; and (v) remove the stigma of schizophrenia. To reduce disparities in physical health, public health strategies and welfare policies must continue to focus on this group of patients.

Disrupting the Adverse Interplay Between Psychiatric and Medical Illnesses

Psychiatric illnesses increase the morbidity and mortality of comorbid medical disease, and current research targets the identification of specific mechanisms that account for this association. Psychotic illness complicates the management of chronic diseases where self-care activities often play a major role, such as in the regulation of blood glucose levels in diabetes. In this issue, Wykes et al. describe an interactive relationship between cognitive functioning and negative symptoms, self-efficacy, and diabetic control in patients with psychotic illnesses and Type 1 diabetes. Although high self-efficacy was associated with better hemoglobin A1C levels in patients with mild negative symptoms and higher cognitive function, in patients with more severe negative symptoms and lower cognitive function, high-self-efficacy was linked to higher A1C levels. These findings point to the need for designing diabetes management plans based on careful assessments of specific psychiatric symptomatology in this population. Severe mental illness is also associated with poor general physical health and higher rates of somatic complaints. Madan and colleagues describe in this issue an integrated model of psychiatric and medical care that substantially reduced physical symptoms in patients with severe mental illness during an 8-week hospitalization, with striking improvements in those presenting with substance abuse and sleep disorders. If these findings are shown to persist after discharge, then accountable care organizations should be encouraged to incorporate this more aggressive approach to caring for this vulnerable population. Such targeted approaches are likely to result in decreased utilization of outpatient medical services and improved long-term outcomes.

Cancer screening, prevention, and treatment in people with mental illness

People with mental illness die decades earlier in the United States compared with the general population. Most of this disparity is related to preventable and treatable chronic conditions, with many studies finding cancer as the second leading cause of death. Individual lifestyle factors, such as smoking or limited adherence to treatment, are often cited as highly significant issues in shaping risk among persons with mental illness. However, many contextual or systems-level factors exacerbate these individual factors and may fundamentally drive health disparities among people with mental illness. The authors conducted an integrative review to summarize the empirical literature on cancer prevention, screening, and treatment for people with mental illness. Although multiple interventions are being developed and tested to address tobacco dependence and obesity in these populations, the evidence for effectiveness is quite limited, and essentially all prevention interventions focus at the individual level. This review identified only one published article describing evidence-based interventions to promote cancer screening and improve cancer treatment in people with mental illness. On the basis of a literature review and the experience and expertise of the authors, each section in this article concludes with suggestions at the individual, interpersonal, organizational, community, and policy levels that may improve cancer prevention, screening, and treatment in people with mental illness.

Cancer survival in the context of mental illness: a national cohort study

OBJECTIVE

To explore the reasons for worse cancer survival in people with experience of mental illness, including differences by cancer type and psychiatric diagnosis.

METHOD

New Zealand breast and colorectal cancer registrations (2006-2010) were linked to psychiatric hospitalization records for adults (18-64 years). Cancer-specific survival was compared for recent psychiatric service users and nonusers using Cox regression. The contributions of deprivation, comorbidity and stage at diagnosis were assessed for those with schizophrenia or bipolar affective disorder (Group A) and others using mental health services (Group B).

RESULTS

Of 8762 and 4022 people with breast and colorectal cancer respectively, 440 (breast) and 190 (colorectal) had recent contact with psychiatric services. After adjusting for confounding, risk of death from breast cancer was increased for Group A [Hazard Ratio (HR) 2.55 (95% confidence interval 1.49-4.35)] and B [HR 1.62 (1.09-2.39)] and from colorectal cancer for Group A [HR 2.92 (1.75-4.87)]. Later stage at diagnosis contributed to survival differences for Group A, and comorbidity contributed for both groups. Fully adjusted HR estimates were breast: Group A 1.65 (0.96-2.84), B 1.41 (0.95-2.09); colorectal: Group A 1.89 (1.12-3.17), B 1.25 (0.89-1.75)].

CONCLUSIONS

The high burden of physical disease and delayed cancer diagnosis in those with psychotic disorders contributes to worse cancer survival in New Zealand psychiatric service users.
