The efficacy of hazard perception training and education: A systematic review and meta-analysis.

Background: Hazard perception (HP) has been argued to improve with experience, with numerous training programs having been developed in an attempt to fast track the development of this critical safety skill. To date, there has been little synthesis of these methods.

Objective: The present study sought to synthesise the literature for all road users to capture the breadth of methodologies and intervention types, and quantify their efficacy.

Perspectives of general practitioners and memory clinic patients on ageing and cognitive decline to inform the design of a decentralised antihypertensive dementia prevention trial.

Background: The global burden dementia is growing each year. Clinical trials investigating approaches to preventing dementia have been occurring for decades, but they are particularly challenging including the requirement to include large numbers of healthy 'at-risk' people who need to be followed up for a long period of time. Community and consumer involvement in trial design helps to ensure that the methods are acceptable to the involved stakeholders, the design and operation of clinical trials are suitable and applicable to the target population, and that key areas of concern are identified and addressed at an early stage.
