Child- and Proxy-reported Differences in Patient-reported Outcome and Experience Measures in Pediatric Surgery: Systematic Review and Meta-analysis.

Purpose: Pediatric health outcomes are often assessed using proxy reports, which may not fully capture children's experiences. Children with surgical conditions face unique, changing healthcare journeys, making accurate representation challenging. This review compares child-reported health status and treatment experiences from Patient-Reported Outcome Measures (PROMs) and Patient-Reported Experience Measures (PREMs) with parent reports.

A park-based group mobility program for older adults with difficulty walking outdoors: a qualitative process evaluation of the Getting Older Adults Outdoors (GO-OUT) randomized controlled trial.

Background: The Getting Older Adults Outdoors (GO-OUT) randomized controlled trial showed that a workshop and 10-week park-based outdoor walk group (OWG) was superior to the workshop and 10 weekly reminders (WR) with increasing walking capacity, but not outdoor walking activity, health-promoting behavior, or successful aging, among older adults with difficulty walking outdoors. The objective of this planned process evaluation was to explore participants' perceptions of mechanisms of impact of and contextual factors influencing experiences with the interventions to help explain the observed intervention effects on study outcomes.

Methods: A qualitative descriptive study involving semi-structured interviews conducted at 6-months post-baseline was conducted.

Use of advanced topic modeling to generate domains for a preference-based index in osteoarthritis.

Background: Health-related quality of life (HRQL) is an important endpoint when evaluating the effectiveness of interventions in people living with hip and knee osteoarthritis (OA). The aim of this study was to generate domains for a new OA-specific preference-based index of HRQL in people living with hip or knee OA.

Methods: The proposed HRQL index was based on a formative measurement model.

Using network analysis to provide evidence for brain health as a unified construct relevant to aging with HIV.

Purpose: Brain health is a dynamic state involving cognitive, emotional, and motor domains. Measuring brain health is a challenge owing to the uncertainty as to whether it is one or many constructs. This study aimed to contribute evidence for brain health as a unified construct by estimating the strength of relationships between and among patient-reported items related to the brain health construct in a population with brain vulnerability owing to HIV.

Disentangling the Effects of Comorbidity and Polypharmacy on Cognitive Function and Physical Frailty in Individuals With HIV.

Objective: To estimate the extent to which comorbidity, polypharmacy, and anticholinergic/sedative burden interrelate to influence cognitive ability, perceived cognitive deficits (PCD), and physical frailty in people living with HIV.

Design: Cross-sectional Structural Equation Modeling of data from 824 older people living with HIV in Canada, participating in the Positive Brain Health Now study.

Method: Structural Equation Modeling was used to link observed variables, including comorbidity, polypharmacy, anticholinergic, and sedative burden, to cognitive ability and 2 latent constructs-physical frailty and PCD.
