ADHD medications use and risk of mortality and unintentional injuries: a population-based cohort study.

We assessed the association between the use of medications for attention-deficit/hyperactivity disorder (ADHD) and the risk of all-cause mortality and unintentional injuries leading to emergency department (ED) or hospital admission in individuals aged ≤24 years with ADHD. We conducted a population-based retrospective cohort study between 2000 and 2021 using Quebec health administrative data. Individuals were followed from the first ADHD diagnosis or ADHD medication claim until turning 25, death, or study end.

Economic impact of the use of the National Surgical Quality Improvement Program.

Objectives: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP®) is a validated, risk-adjusted database for improving the quality and security of surgical care. ACS NSQIP can help participating hospitals target areas that need improvement. The aim of this study was to systematically review the literature analyzing the economic impact of using NSQIP.

Investing in a healthy lifestyle strategy: is it worth it?

Objectives: In Quebec, various actors fund activities aimed at increasing physical activity, improving eating habits and reducing smoking. The objective was to evaluate how effective does the healthy lifestyle habits promotion (HLHP) strategy need to be to make to offset its costs.

Methods: First, we built the logic model of the HLHP strategy.

[Effectiveness of psychotherapy compared to pharmacotherapy for the treatment of anxiety and depressive disorders in adults: A literature review].

Introduction In Quebec, mental disorders affect one in five people in their lifetime. Anxiety and depressive disorders are the main common or moderate mental health disorders. They affect both the individuals with the disorder and the people around them and have substantial economic impact.

The economic value of Quebec's water fluoridation program.

Aim: Dental caries is a major public health problem worldwide, with very significant deleterious consequences for many people. The available data are alarming in Canada and the province of Quebec. The water fluoridation program has been shown to be the most effective means of preventing caries and reducing oral health inequalities.

Screening for glaucoma using GDx-VCC in a population with ≥1 risk factors.

Objective: To estimate the diagnostic accuracy of the GDx-VCC for glaucoma screening in a population with ≥1 risk factors for glaucoma.

Design: Cross-sectional evaluation of a diagnostic test for screening.

Participants: Two hundred forty-seven community-based volunteer participants with risk factors for glaucoma.

Partnership for fragility bone fracture care provision and prevention program (P4Bones): study protocol for a secondary fracture prevention pragmatic controlled trial.

Background: Fractures associated with bone fragility in older adults signal the potential for secondary fracture. Fragility fractures often precipitate further decline in health and loss of mobility, with high associated costs for patients, families, society and the healthcare system. Promptly initiating a coordinated, comprehensive pharmacological bone health and falls prevention program post-fracture may improve osteoporosis treatment compliance; and reduce rates of falls and secondary fractures, and associated morbidity, mortality and costs.

Screening for glaucoma in high-risk populations using optical coherence tomography.

Objective: To estimate the diagnostic accuracy of Stratus optical coherence tomography (OCT) for glaucoma screening in high-risk populations.

Design: Cross-sectional evaluation of a diagnostic test for screening.

Participants: Three hundred thirty-three community-based volunteer participants with risk factors for glaucoma.

Validity of screening for glaucomatous optic nerve damage using confocal scanning laser ophthalmoscopy (Heidelberg Retina Tomograph II) in high-risk populations: a pilot study.

Purpose: To evaluate whether confocal scanning laser ophthalmoscopy (Heidelberg Retina Tomograph II [HRT II], Heidelberg Engineering, Heidelberg, Germany) is a valid tool for the detection of glaucomatous optic nerve damage.

Design: Observational, cross-sectional, nonconsecutive study in Montreal, Canada.

Participants: Three hundred three nonconsecutive, high-risk persons were enrolled during a 6-month period.

The effect of compression on clinical diagnosis of glaucoma based on non-analyzed confocal scanning laser ophthalmoscopy images.

Background And Objective: To evaluate the effect of different image compression formats of non-analyzed Heidelberg Retina Tomography (HRT; Heidelberg Engineering, Heidelberg, Germany) images on the diagnosis of glaucoma by ophthalmologists.

Materials And Methods: Thirty-three topographic and reflectance images taken with the HRT representing different levels of disease were transformed using nine different compression formats. Three independent ophthalmologists, masked as to contour line and stereometric parameters, classified the original and compressed HRT images as normal, suspected glaucoma, or glaucoma, and Kappa agreement coefficients were calculated.
