Delay in the Diagnosis of Breast and Colorectal Cancer in People With Severe Mental Disorders

Diagnostic inequalities relating to physical healthcare among people with mental health conditions: a systematic review

Background

Inaccurate diagnosis of physical health problems in people with mental health conditions may contribute to poorer health outcomes. We review the evidence on whether individuals with mental health conditions are at risk of diagnostic inequalities related to their physical health.

Methods

We searched MEDLINE, PsycINFO, Embase, and CINAHL, 1 September 2002-18 Septemebr 2024 (PROSPERO 2022: CRD42022375892). Seventy-nine studies were eligible for inclusion. Risk of Bias (RoB) was assessed using the Newcastle-Ottawa or RoB2 tools and results were presented as a narrative synthesis.

Findings

Findings from the included studies suggests that people with mental health conditions face diagnostic inequalities for their physical health. A minority of studies adopted a design that specifically measured professional- and service-related factors associated with diagnostic inequalities. Most studies, however, measured diagnostic endpoints only, meaning that no inference could be made regarding the relative impact of patients' and clinicians' behaviour in producing inequalities.

Interpretation

Further investigations should consider the stage of the diagnostic process at which inequalities occur, to improve knowledge of the mechanisms underpinning diagnostic inequalities, and support the development of targeted improvement interventions.

Bridging the Gap: Interventions to Increase Cancer Screening Adherence in Individuals with Mental Disorders-A Systematic Review

Patients with mental illnesses adhere to organized cancer screening programs less frequently than the general population. This systematic review aims to examine the literature to identify studies that evaluate interventions designed to increase cancer screening adherence in people with mental disorders. The review protocol was registered (CRD42024510431) and Pubmed and Scopus were searched up to January 2024. Breast, colorectal, or cervical cancer screening were considered. We adhered to the PROSPERO guidelines. Study quality was assessed. Overall, six articles were included: two RCT studies, two before-after studies, and two cohort studies. Four interventions were conducted in the USA, one in Canada, and one in Japan. Two studies evaluated all three cancer screening programs, two studies evaluated breast cancer screenings, and two studies evaluated colorectal cancer screenings. The proposed interventions included patient navigation, case management, and support from staff members along with educational modules, decision counselling sessions, and enhanced primary care. The most consistent improvements in screening adherence were observed in breast and colorectal cancer screenings compared to usual care, particularly through interventions like patient navigation (colorectal cancer: 47.1% vs. 11.8%, p < 0.001) and case management. Further evaluations of interventions and their costs are still needed.

The Challenging Problems of Cancer and Serious Mental Illness

PURPOSE OF REVIEW: Patients with Serious Mental Illness (SMI) are reported to be at higher risk for somatic disorders (e.g. cardiovascular and metabolic diseases) and higher mortality, compared to the general population, because of the consequences of SMI including psychotropic medication side effects, sedentary and unhealthy lifestyle, difficult access to physical health care. The aim of this review was to examine the current evidence regarding oncology, focusing on the problem of cancer among patients with SMI. RECENT FINDINGS: Compared to the general population, individuals with SMI showed a lower rate of screening for cancer, suboptimal standard cancer treatment, delayed treatment, and higher mortality from cancer. Several factors, including those related to the patient, the health-care system, and the social context, are involved in these negative outcomes. It is therefore necessary to raise awareness and alert clinicians in oncology settings to the challenging problem of cancer among patients with SMI, a marginalized and vulnerable segment of the population that can be at risk for not receiving proper cancer prevention and care. Evidence supports the mandatory need for an interdisciplinary approach involving psychiatry and mental health services.

Barriers and facilitators for people with severe mental illness accessing cancer screening: A systematic review

OBJECTIVE

Evidence suggests that people with severe mental illness (PwSMI) are 2.1 times more likely to die from cancer before the age of 75, compared to people without Severe mental illness (SMI). Yet, cancer screening uptake is low among PwSMI. This mixed-methods systematic review aimed to identify the barriers and facilitators for PwSMI deciding to access and attend primary cancer screening of the cervix, breast and colon.

METHODS

Six electronic databases and two grey literature sources were searched, with 1017 records screened against inclusion criteria. Included papers were appraised and data synthesised using the constructs of Normalisation Process Theory.

RESULTS

Twenty papers met the inclusion criteria. Factors that impact upon uptake of PwSMI accessing cancer screening were found to include age, gender, race, and income. Common barriers to attending screening included poor communication from healthcare staff, stigmatising attitudes, and accessibility problems such as no access to transportation. While, facilitators included social support from friends, family, and healthcare providers.

CONCLUSIONS

Due to ease and privacy, colorectal screening was found to have fewer barriers when compared to cervical and breast screening. The review identified multiple barriers that can be addressed and targeted to support decision-making for cancer screening among PwSMI. The protocol was registered with PROSPERO (CRD42022331781).

Experience and perspectives of end-of-life care discussion and physician orders for life-sustaining treatment of Korea (POLST-K): a cross-sectional study

BACKGROUND

This study aimed to identify the healthcare providers' experience and perspectives toward end-of-life care decisions focusing on end-of-life discussion and physician's order of life-sustaining treatment documentation in Korea which are major parts of the Life-Sustaining Treatment Act.

METHODS

A cross-sectional survey was conducted using a questionnaire developed by the authors. A total of 474 subjects-94 attending physicians, 87 resident physicians, and 293 nurses-participated in the survey, and the data analysis was performed in terms of frequency, percentage, mean and standard deviation using the SPSS 24.0 program.

RESULTS

Study results showed that respondents were aware of terminal illness and physician's order of life-sustaining treatment in Korea well enough except for some details. Physicians reported uncertainty in terminal state diagnosis and disease trajectory as the most challenging. Study participants regarded factors (related to relationships and communications) on the healthcare providers' side as the major impediment to end-of-life discussion. Study respondents suggested that simplification of the process and more staff are required to facilitate end-of-life discussion and documentation.

CONCLUSION

Based on the study results, adequate education and training for better end-of-life discussion are required for future practice. Also, a simple and clear procedure for completing a physician's order of life-sustaining treatment in Korea should be prepared and legal and ethical advice would be required. Since the enactment of the Life-Sustaining Treatment Act, several revisions already have been made including disease categories, thus continuous education to update and support clinicians is also called for.

Psychological distress and bowel cancer screening participation

OBJECTIVE

To better understand barriers to participation in mail-out bowel cancer screening programs, two survey studies tested the relationship between psychological distress and self-reported bowel cancer screening.

METHODS

First, a nationally representative sample of Australians N = 5421 completed measures of bowel cancer screening and psychological distress (using the Kessler Psychological Distress Scale; K10). Second, N = 479 completed a survey measuring participation in the National Bowel Cancer Screening Program (NBCSP) and psychological distress using the Depression, Anxiety and Stress Scale. In both studies, logistic regressions were conducted to test relationships between psychological distress and self-reported screening participation.

RESULTS

Study one found that psychological distress had a significant quadratic effect on having ever screened for bowel cancer, where screening rates were similar for those with low, moderate, or high levels of distress, but were lower for those with very high levels of distress. In study two, depression scores had a negative linear relationship with NBCSP participation (higher depression levels were associated with lower screening participation), and anxiety had a quadratic effect whereby NBCSP participation rates were higher with increasing levels of anxiety except in the severe category, where participation was significantly lower.

CONCLUSIONS

Findings indicate that psychological distress has a complex relationship with screening, and those with extreme levels of distress consistently show lower participation rates. Special efforts to encourage screening may be required for those experiencing extreme psychological distress and mental health disorders.

Breast Cancer Care Pathways for Women with Preexisting Severe Mental Disorders: Evidence of Disparities in France?

The excess cancer mortality in persons with severe mental illness (SMI) has been well documented, and research suggests that it may be influenced by care-related factors. Our objective was to assess breast cancer care pathways in women with SMI in France, using an exhaustive population-based data-linkage study with a matched case-control design. The cases were 1346 women with incident breast cancer in 2013/2014 and preexisting SMI who were matched with three controls without SMI presenting similar demographics, initial breast cancer type, and year of incidence. We compared cancer care pathways and their quality for cases and controls, using a consensual set of indicators covering diagnosis, treatment, follow-up, and mortality (until 2017). After adjusting for covariates, cases had lower odds to undergo the main diagnostic tests, lumpectomy, adjuvant chemotherapy, and radiotherapy, as well as hormone therapy, but higher odds for mastectomy. Suboptimal quality in cancer pathways was observed for both groups, but to a higher extent for cases, especially for not receiving timely care after diagnosis and post-treatment follow-up. Breast cancer mortality, considering competing risks of deaths, was significantly elevated in women with SMI. These findings highlight disparities in cancer care pathways for individuals with SMI, as well as specific aspects of the care continuum which could benefit from targeted actions to reach equity of outcomes.

Impact of a pre-existing diagnosis of mental illness on stage of breast cancer diagnosis among older women

PURPOSE

Having a mental illness increases risk of mortality for women with breast cancer, partly due to barriers to accessing recommended care (e.g., cancer screening). Early detection is one important factor in breast cancer survival. To further understand this disparity in survival, we examined whether older women with mental illness are more likely to be diagnosed with later-staged breast cancers compared to women without mental illnesses.

METHODS

We used 2005-2015 SEER-Medicare data to identify AJCC stage I-IV breast cancer patients with and without a history of mental illness prior to cancer diagnosis. We used generalized ordinal regression to examine associations between mental illness diagnoses and stage at diagnosis, controlling for age, race/ethnicity, income, comorbidities, primary care use, rurality, and marital status.

RESULTS

Among 96,034 women with breast cancer, 1.7% have a serious mental illness (SMI), 19.9% depression or anxiety, and 7.0% other mental illness. Those with SMI have 40% higher odds of being diagnosed with AJCC Stages II, III than Stage I; women with depression/anxiety have 25% lower odds of being diagnosed with Stage IV cancer than Stage I; and women with other mental illnesses have similar odds of being diagnosed in later stages.

CONCLUSION

Women with SMI have higher odds of being diagnosed at later stages, which likely contributes to higher mortality after breast cancer. Surprisingly, women with depression and anxiety have a lower risk of being diagnosed with Stage IV cancer. Earlier breast cancer diagnosis in women with SMI is an important goal for reducing disparities breast cancer survival.

Exposure to Childhood Healthcare Discrimination and Healthcare Avoidance among Transgender and Gender Independent Adults during a Global Pandemic

Transgender and gender-independent individuals (TGI) encounter myriad barriers to accessing affirming healthcare. Healthcare discrimination and erasure exposure among TGI individuals is vital to understanding healthcare accessibility, utilization behaviors, and health disparities in this population. Exposure to gender identity-related healthcare discrimination and erasure in childhood may contribute to TGI adults' healthcare utilization behaviors. The commonality of childhood exposure to gender identity-related healthcare discrimination and its relationship to healthcare avoidance during the early months of the COVID-19 pandemic among TGI adults were explored. TGI adults aged 18 to 59 (N = 342) in the United States were recruited online during the summer of 2020. Among individuals who reported childhood exposure to gender identity-related healthcare discrimination, 51% reported experiencing two or more distinct forms of discrimination. Hierarchical logistic regression indicated that exposure to healthcare discrimination in childhood significantly increased the odds of healthcare avoidance during the early months of the COVID-19 pandemic, after accounting for demographic factors and self-reported COVID-19 symptoms (odds ratio = 1.30, 95% confidence interval = 1.10, 1.54). These findings suggest that childhood exposure to gender identity-related healthcare discrimination is a prominent barrier to the utilization of healthcare for TGI adults, even during a global pandemic.

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.
