Excess mortality from cancer in people with mental illness-Out of sight and out of mind

Cancer diagnosis after emergency presentations in people with mental health and substance use conditions: a national cohort study

BACKGROUND

Cancer survival and mortality outcomes for people with mental health and substance use conditions (MHSUC) are worse than for people without MHSUC, which may be partly explained by poorer access to timely and appropriate healthcare, from screening and diagnosis through to treatment and follow-up. Access and quality of healthcare can be evaluated by comparing the proportion of people who receive a cancer diagnosis following an acute or emergency hospital admission (emergency presentation) across different population groups: those diagnosed with cancer following an emergency presentation have lower survival.

METHODS

National mental health service use datasets (2002-2018) were linked to national cancer registry and hospitalisation data (2006-2018), to create a study population of people aged 15 years and older with one of four cancer diagnoses: lung, prostate, breast and colorectal. The exposure group included people with a history of mental health/addiction service contact within the five years before cancer diagnosis, with a subgroup of people with a diagnosis of bipolar disorder, schizophrenia or psychotic disorders. Marginal standardised rates were used to compare emergency presentations (hospital admission within 30 days of cancer diagnosis) in the exposure and comparison groups, adjusted for age, gender (for lung and colorectal cancers), ethnicity, area deprivation and stage at diagnosis.

RESULTS

For all four cancers, the rates of emergency presentation in the fully adjusted models were significantly higher in people with a history of mental health/addiction service use than people without (lung cancer, RR 1.19, 95% CI 1.13, 1.24; prostate cancer RR 1.69, 95% CI 1.44, 1.93; breast cancer RR 1.42, 95% CI 1.14, 1.69; colorectal cancer 1.31, 95% CI 1.22, 1.39). Rates were substantially higher in those with a diagnosis of schizophrenia, bipolar disorder or psychotic disorders.

CONCLUSIONS

Implementing pathways for earlier detection and diagnosis of cancers in people with MHSUC could reduce the rates of emergency presentation, with improved cancer survival outcomes. All health services, including cancer screening programmes, primary and secondary care, have a responsibility to ensure equitable access to healthcare for people with MHSUC.

Dealing With Discrimination in Physical Health Care Services: Strategies of People With Mental Health and Substance Use Conditions

Discrimination against people with mental health and substance use conditions (MHSUC) by health professionals contributes to the poor physical health outcomes this group experiences. We surveyed people with MHSUC in Aotearoa New Zealand to explore how they experienced and responded to discrimination from physical health services. Participants identified 6 strategies used to avoid or minimize the impact of discrimination. Avoidance strategies included not seeking help, not disclosing MHSUC diagnoses and changing or seeking out health professionals who did not behave in discriminatory ways. Minimizing strategies were being a "model patient," taking a support person to consultations or advocating for what they needed, even in the face of discrimination. Physical health services must focus on providing non-discriminatory care to reduce the need for compensatory strategies and improve care of physical illness for people with MHSUC.
