Cancer staging in individuals with a severe psychiatric illness: a cross-sectional study using population-based cancer registry data.

ABSTRACT: BACKGROUND:Advanced cancer stage at diagnosis may explain high cancer mortality among patients with a severe psychiatric illness (SPI). Studies to date investigating advanced stage cancer at diagnosis as a potential explanation for high cancer mortality in individuals with a history of mental illness have been inconclusive. We examined the relationship between a SPI history and unknown cancer stage at diagnosis in colorectal cancer (CRC) patients. METHODS:This was a population-based, cross-sectional study using linked administrative databases of CRC patients diagnosed between 01/04/2007 and 31/12/2012. Individuals who had a history of mental illness but did not meet the definition of a SPI were excluded. An SPI was measured in the 5 years prior to the cancer diagnosis and categorized as inpatient, outpatient or no SPI. Individuals with a best stage in Stage 0 to Stage IV were considered staged and absence of staging information was defined as unknown stage. The risk of unknown stage cancer was estimated using modified Poisson regression. RESULTS:The final study cohort included 24,507 CRC patients. 258 (1.1%) individuals experienced a history of inpatient SPI and 482 (2.0%) experienced outpatient SPI. After adjusting for confounders, CRC patients with an inpatient or outpatient history of SPI were at greater risk of having missing TNM stage at diagnosis, compared to patients with no history of a mental illness (RR 1.45 (95% CI: 1.14-1.85) and RR1.17 (95% CI 0.95-1.43), respectively). The results did not change when alternate practices to assign SPI history using administrative data were used. CONCLUSIONS:Individuals with an SPI, especially those with a psychiatric admission, were more likely to have missing stage data compared to individuals without a history of a mental illness. Incomplete and low quality cancer staging data likely undermines the quality of cancer care following initial diagnosis. Understanding why patients with an SPI are missing this information is a critical first step to providing excellent care to this vulnerable population.

Project description: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.

Project description:BackgroundPhelan-McDermid syndrome (PMS) is a genetic condition characterized by intellectual disability, speech and language deficits, hypotonia, autism spectrum disorder, and epilepsy. PMS is caused by 22q13.33 deletions or mutations affecting SHANK3, which codes for a critical scaffolding protein in excitatory synapses. SHANK3 variants are also known to be associated with an increased risk for regression, as well as for psychiatric disorders, including bipolar disorder and catatonia. This study aimed to further describe these phenomena in PMS and to explore any relationship between psychiatric illness and regression after early childhood.MethodsThirty-eight people with PMS were recruited to this study through the Phelan-McDermid Syndrome Foundation based on caregiver report of distinct development of psychiatric symptoms. Caregivers completed a clinician-administered semi-structured interview focused on eliciting psychiatric symptomatology. Data from the PMS International Registry were used to confirm genetic diagnoses of participants and to provide a larger sample for comparison.ResultsThe mean age of the 38 participants was 24.7 years (range = 13 to 50; SD = 10.06). Females (31 of 38 cases; 82%) and sequence variants (15 of 38 cases; 39%) were over-represented in this sample, compared to base rates in the PMS International Registry. Onset of psychiatric symptoms occurred at a mean age of 15.4 years (range = 7 to 32), with presentations marked by prominent disturbances of mood. Enduring substantial loss of functional skills after onset of psychiatric changes was seen in 25 cases (66%). Symptomst indicative of catatonia occurred in 20 cases (53%). Triggers included infections, changes in hormonal status, and stressful life events.ConclusionsThis study confirms that individuals with PMS are at risk of developing severe neuropsychiatric illness in adolescence or early adulthood, including bipolar disorder, catatonia, and lasting regression of skills. These findings should increase the awareness of these phenotypes and lead to earlier diagnosis and the implementation of appropriate interventions. Our findings also highlight the importance of genetic testing in the work-up of individuals with intellectual disability and acute psychiatric illness or regression. Future research is needed to clarify the prevalence and nature of psychiatric disorders and regression among larger unbiased samples of individuals with PMS.

Project description:BackgroundSuper diversity has become a twenty-first-century phenomena in the UK. The Five Year Forward View Plan for Mental Health commits to improving access to Perinatal Mental Health services for all new mothers. Existing research indicates various postnatal mental illness aetiologies, traditional practices and beliefs, which are important to explore during medical consultation to achieve a collaborative relationship between the patient and clinician. The study of severe postnatal psychiatric illnesses is well established in the quantitative literature; however, the subjective experiences of mothers with severe psychiatric illnesses after childbirth have been given little attention. The aim of this systematic review is to synthesise the small body of qualitative findings, which will achieve a deeper understanding of mothers' experiences and understandings. This integration of qualitative data is invaluable in facilitating culturally competent strategies in Western settings and informing future research.Methods/designThis protocol proposes a systematic review of qualitative literature of severe postnatal psychiatric illnesses, using a meta-ethnography approach following the PRISMA-P guidelines. A comprehensive search strategy will be developed to undertake a systematic search via online databases to identify eligible articles. Studies will be considered for eligibility if they include mothers aged 18 and over who have been diagnosed with a severe psychiatric illness during the postnatal period; present primary data on women's illness experiences; use qualitative methods. Titles and abstracts will be screened by the primary reviewer to identify potential papers. Two independent reviewers will access and read texts in full and agree on the final list of included studies. Discrepancies will be resolved via consultation with a third independent reviewer. The final list of included studies for review will be methodologically appraised by two independent reviewers using the Critical Appraisal Skills Programme. This systematic review protocol has been registered with the International Prospective Register of Systematic Reviews (PROSPERO): CRD42018093674.DiscussionTo date, no systematic review following a meta-ethnographic approach on qualitative explorations of mothers worldwide diagnosed with severe postnatal psychiatric illnesses has been conducted. An amalgamation of this information enables a deeper understanding of how severe postnatal psychiatric illnesses manifests across cultures. This information is useful when devising culturally competent care.Systematic review registrationCRD42018093674.
