Background: Compared with those with a higher socio-economic position (SEP), individuals with a lower SEP have higher cancer morbidity and mortality. However, the contribution of modifiable risk factors to these inequities is not known. This study aimed to quantify the mediating effects of modifiable risk factors to associations between SEP and cancer morbidity and mortality.Methods: This study used a prospective observational cohort design. We combined eight cycles of the Canadian Community Health Survey (2000/2001-2011) as baseline data to identify a cohort of adults (≥35 years) without cancer at the time of survey administration (n = 309 800). The cohort was linked to the Discharge Abstract Database and the Canadian Mortality Database for cancer morbidity and mortality ascertainment. Individuals were followed from the date they completed the Canadian Community Health Survey until 31 March 2013. Dates of individual first hospitalizations for cancer and deaths due to cancer were captured during this time period. SEP was operationalized using a latent variable combining measures of education and household income. Self-reported modifiable risk factors, including smoking, excess alcohol consumption, low fruit-and-vegetable intake, physical inactivity and obesity, were considered as potential mediators. Generalized structural equation modelling was used to estimate the mediating effects of modifiable risk factors in associations between low SEP and cancer morbidity and mortality in the total population and stratified by sex.Results: Modifiable risk factors together explained 45.6% of associations between low SEP and overall cancer morbidity and mortality. Smoking was the most important mediator in the total population and for males, accounting for 15.5% and 40.2% of the total effect, respectively. For females, obesity was the most important mediator.Conclusions: Modifiable risk factors are important mediators of socio-economic inequities in cancer morbidity and mortality. Nevertheless, more than half of the variance in these associations remained unexplained. Midstream interventions that target modifiable risk factors may help to alleviate inequities in cancer risk in the short term. However, ultimately, upstream interventions that target structural determinants of health are needed to reduce overall socio-economic inequities in cancer morbidity and mortality.

Context Checklists are commonly used in the assessment of procedural competence. However, on most checklists, high scores are often unable to rule out incompetence as the commission of a few serious procedural errors typically results in only a minimal reduction in performance score. We hypothesised that checklists constructed based on procedural errors may be better at identifying incompetence. Objectives This study sought to compare the efficacy of an error-focused checklist and a conventionally constructed checklist in identifying procedural incompetence. Methods We constructed a 15-item error-focused checklist for lumbar puncture ( LP) based on input from 13 experts in four Canadian academic centres, using a modified Delphi approach, over three rounds of survey. Ratings of 18 video-recorded performances of LP on simulators using the error-focused tool were compared with ratings obtained using a published conventional 21-item checklist. Competence/incompetence decisions were based on global assessment. Diagnostic accuracy was estimated using the area under the curve ( AUC) in receiver operating characteristic analyses. Results The accuracy of the conventional checklist in identifying incompetence was low ( AUC 0.11, 95% confidence interval [ CI] 0.00-0.28) in comparison with that of the error-focused checklist ( AUC 0.85, 95% CI 0.67-1.00). The internal consistency of the error-focused checklist was lower than that of the conventional checklist (α = 0.35 and α = 0.79, respectively). The inter-rater reliability of both tools was high (conventional checklist: intraclass correlation coefficient [ ICC] 0.99, 95% CI 0.98-1.00; error-focused checklist: ICC 0.92, 95% CI 0.68-0.98). Conclusions Despite higher internal consistency and inter-rater reliability, the conventional checklist was less accurate at identifying procedural incompetence. For assessments in which it is important to identify procedural incompetence, we recommend the use of an error-focused checklist. [ABSTRACT FROM AUTHOR]

Background: The quality of medical student and resident clinical evaluation reports submitted by rotation supervisors is a concern. The effectiveness of faculty development (FD) interventions in changing report quality is uncertain. Aims: This study assessed whether faculty could be trained to complete higher quality reports. Method: A 3-h interactive program designed to improve evaluation report quality, previously developed and tested locally, was offered at three different Canadian medical schools. To assess for a change in report quality, three reports completed by each supervisor prior to the workshop and all reports completed for 6 months following the workshop were evaluated by three blinded, independent raters using the Completed Clinical Evaluation Report Rating (CCERR): a validated scale that assesses report quality. Results: A total of 22 supervisors from multiple specialties participated. The mean CCERR score for reports completed after the workshop was significantly higher (21.74 ± 4.91 versus 18.90 ± 5.00, p = 0.02). Conclusions: This study demonstrates that this FD workshop had a positive impact upon the quality of the participants' evaluation reports suggesting that faculty have the potential to be trained with regards to trainee assessment. This adds to the literature which suggests that FD is an important component in improving assessment quality. [ABSTRACT FROM AUTHOR]

Background: Adolescent cannabis use is perceived as a risky behavior, has been linked with many negative health outcomes, and is increasingly being connected with stigma.Methods: The purpose of this study is to investigate how cannabis use is associated with potentially stigmatizing markers of identity among adolescents two waves of a repeat cross-sectional survey (2015 N = 12,110; 2017 N = 15,191) of high schools students in seven Canadian provinces. Students were asked about ever use of cannabis, as well as "stigma markers", including their current living arrangement, mother's education, and ethnicity. Multivariable logistic regression models were used to examine associations between cannabis use and stigma markers.Results: After adjusting models for grade, gender, and province of residence, students who did not live with their mothers had higher odds of cannabis use relative to students living with their mothers [OR = 1.94, 95% CI 1.62-2.31]. Low maternal education was also significantly associated with cannabis use, as was ethnicity (students who identified as Indigenous had 3.38 (95% CI 2.29-4.99) times higher odds of using cannabis compared to students who identified as "white" in 2017). Findings related to attending school in a rural (vs. urban) area (2015 OR = 1.33 95% CI 0.99-1.78; 2017 OR = 1.44 95% CI 0.9 to -2.15) and low SES (2015 OR = 0.99, 95% 0.98-1.00; 2017 OR = 1.00, 95% CI 0.98-1.01) were more marginal.Conclusions: Future research should explore cannabis initiation experiences among vulnerable groups to better understand potential stigma triggers.
