London Asthma Decision Support tool

In London it is estimated 600,000 people suffer from asthma, including almost a quarter of a million children. Owing to its high levels of air pollution, these figures are some of the worst asthma rates in the country, with research also routinely showing that poorer areas of the Capital have far higher hospital admission rates than more affluent ones. 

LADS (the London Asthma Decision Support Tool) a new NHS data tool that brings together air pollution, demographic and social deprivation data with routinely collected NHS data for the first time ever,  allows clinical teams to intervene much earlier in the patient pathway and improve outcomes, but also focus on identifying and investigating areas of health inequity across the capital.

The London Asthma Decision Support (LADS) tool

LADS is one of NHS England’s pathfinder projects, commissioned as part of the Data Saves Lives Strategy and implemented as part of the London Health Data Strategy, and was developed with clinicians from across north west and south east London Integrated Care Systems (ICS). Gaining a picture of asthma outcomes across ICS borders means that never-before possible system-level analysis can be performed and fed back to clinicians at a Primary Care Network (PCN) level, so relevant hyper-local interventions can contribute to London-wide improvements in asthma care.

The collaborative approach between North West London (NWL) and South East London (SEL) Integrated Care Boards (ICBs), means that 80 PCNs will be able to access data, which will be analysed within NWL’s secure data environment, Discover-NOW. This use of data has been guided by the recommendations gained from the London Health Data Strategy deliberations undertaken by ICHP in 2022 and, as such, is fully supported by citizens.

The tool is available across NWL and SEL.

The true power of this data is that it will allow an understanding of outcomes across a population enabling increased support & intervention to be delivered to areas of need and in a way that supports local delivery approaches. We hope to be able to extend the use of this tool across the whole of London.
