Recruitment of Young Gay, Bisexual, and Other Men Who Have Sex With Men for a Web-Based Human Papillomavirus Vaccination Intervention: Differences in Participant Characteristics and Study Engagement by Recruitment Source in a Randomized Controlled Trial.

Background: Young gay, bisexual, and other men who have sex with men have been referred to as a "hard-to-reach" or "hidden" community in terms of recruiting for research studies. With widespread internet use among this group and young adults in general, web-based avenues represent an important approach for reaching and recruiting members of this community. However, little is known about how participants recruited from various web-based sources may differ from one another.

Exome Sequencing in the Diagnostic Pathway for Suspected Rare Genetic Diseases: Does the Order of Testing Affect its Cost-Effectiveness?

Background: Patients with suspected rare diseases often experience lengthy and uncertain diagnostic pathways. This study aimed to estimate the cost-effectiveness of exome sequencing (ES) in different positions in the diagnostic pathway for patients suspected of having a rare genetic disease.

Methods: Data collected retrospectively from 305 patients suspected of having a rare genetic disease (RGD), who received clinical-grade ES and participated in the Canadian multicentre Care4Rare-SOLVE study, informed a discrete event simulation of the diagnostic pathway.

Comparison of Physical Frailty Assessments in Heart Failure With Preserved Ejection Fraction.

Background: Frailty is a known determinant of poor clinical outcomes in heart failure with preserved ejection fraction (HFpEF). However, prevalence estimates and effect sizes vary in part due to multiple tools available to measure frailty.

Objectives: This study aimed to compare the prevalence and prognostic value of six commonly used frailty assessments in adults with HFpEF.

Estimating the Budget Impact and Joint Replacement Avoidance by Implementing a Standardized Education and Exercise Therapy Program for Hip and Knee Osteoarthritis in a Publicly Insured Healthcare System.

Objective: Estimate the budget impact of funding a standardized education and exercise therapy program (GLA:D®) for people with hip and knee OA waiting for total joint replacement (TJR) consultation in a universal publicly insured healthcare system in Canada.

Methods: We built a budget impact analysis (BIA) model to estimate the annual cost of providing GLA:D® program to people waiting for TJR consultation and then forecasted a three-year budget cycle. The base case assumes 40% attend GLA:D®, 11% avoid surgery, uniform care delivery, training costs are incurred separately, and the healthcare system has enough trained staff to meet demand.
