I’m interested in the impact of change in the organisation, management and composition of the healthcare workforce on both patient and staff outcomes. Linked to this is an interest in quality measurement and in particular using outcome data to improve practice. My current or recent work includes - the RN4CAST study: an international study being undertaken by a consortium of 13 countries in Asia, Africa, Europe and the united States , which is working with professor Linda Aiken to replicate and extend her seminal studies on the link between nurse staffing and mortality; - a series of studies exploring links between nurse staffing and quality and outcomes in general practice.
