Our objective was compare rates diagnosis across different health‐care regions tests features both health access regional populations. This a population‐based retrospective ecological observational study 12,959 patients with between January 1, 2000 December 31, 2008 Ontario Canada based on...

Background: Allergy is diagnosed from typical symptoms, and tests are performed to incriminate the suspected precipitant. Skin prick (SPTs) commonly performed, inexpensive, give immediate results. Laboratory (ImmunoCAP) for serum allergen-specific IgE antibodies usually more selectively. The immuno-solid phase allergen chip (ISAC) enables testing specific against multiple components in a multiplex assay. Methods: We retrospectively analysed clinic letters, case notes, laboratory results of...

Abstract Background Cancer is a leading cause of death among people living with intellectual or developmental disabilities (IDD). Although studies have documented lower cancer screening rates, there limited epidemiological evidence quantifying potential diagnostic delays. This study explores the risk metastatic stage for IDD compared to those without breast (female), colorectal, and lung patients in Canada. Methods Separate population‐based cross‐sectional were conducted Ontario Manitoba by...

The diagnostic interval a useful approach to conceptualizing time‐to‐diagnosis within the healthcare system and understanding journey. Adults with severe psychiatric illness (SPI) are less likely participate in screening more be diagnosed advanced cancers. We investigated association between having an SPI interval.

To assess the association between surgeons thyroidectomy case volume and disease-free survival (DFS) for patients with well-differentiated thyroid cancer (WDTC). A secondary objective was to a surgeon cutoff optimize outcomes in those WDTC. We hypothesized that will be an important predictor of DFS WDTC after adjusting hospital sociodemographic clinical factors.In this retrospective population-based cohort study, we identified Ontario, Canada, who underwent confirmed by both hospital-level...
