Public Health England's INHALE data tool aims to help commissioners assess the impact of respiratory disease on local populations, assess variation and identify the services required to meet those needs. INHALE is intended to provide a single source of data on the burden of, and quality of care for respiratory disease in England. It takes into account the work of the Lung and Asthma Information agency (LAIA), and recent initiatives such as Impress. It was set-up to provide accessible, actionable data showing clinical variation, trends in disease patterns and quality of care to those working in or interested in improving respiratory healthcare services and outcomes. This data is displayed in the form of interactive maps and charts.
