Health Outcomes Travel Tool



The SDU’s Health Outcomes of Travel Tool (HOTT) helps NHS organisations measure the impact their travel and transport has in environmental, financial and health terms. An innovative tool it allows the quantification of impacts from different travel sources to allow the creation of a plan and targeted initiatives to reduce the NHS's impact from travel and transport.

Watch the intro video, download the tool and guidance below





HOTT is comprised of three interfaces specific to each organisation type:

  • Provider (non-Ambulance) - An interface for Providers, who are not ambulance trusts which best reflects their core operations; the movement of staff. Patients and visitors. 
  • Ambulance Providers – This interface also includes fleet specific data inputs and impacts for ambulances, rapid response vehicles and patent transport fleet for example. 
  • Primary Care - This interface allows CCGs to assess their own impacts alongside the travel impacts of primary care delivered within the CCG boundary - the tool currently has a caveat about unknown quality of the calculated baseline business mileage figure. 

Please note a fourth interface is in development to measure the impacts from any internal logistics fleet such as combi vans to HGVs and will also be useful when engaging you’re your supply chain and assessing the impacts any transport services including the delivery of goods. 

To help understand how the tool can benefit you the SDU have produced supporting guidance and tutorials: 
  • Short guide 
  • Full guide  - including step by step guide for using the tool. The full guide also details the data sources and assumptions used to create the tool. 

Video tutorials

Available to assist you using each interface:



 The tool was commissioned by the SDU and developed by Mike Holland at EMRC.

Please can you share with the SDU your version of the HOTT once analysis has been undertaken, if this has been modeling one intervention or assessing your impact over several years, we are very keen to understand how the tool is begin used, how accurate the baseline is and where we can further improve the tool.  If you have any questions or feedback please contact Rick Lomax at the SDU - richard.lomax@nhs.net

Please note V1.7 launched 03/07/2017 - see version control in introduction tab for details

Travel and transport linked to NHS services generates a significant share of UK traffic, currently estimated at around 5%, producing air pollution, accidents and noise. Air pollution is widely recognised as being a significant burden on health.  A 2017 report from the Royal Colleges of Physicians and Paediatrics and Child Health estimated that UK wide travel and transport impact on mortality is equivalent to 40,000 deaths a year, in addition to numerous effects on respiratory and cardiovascular health. 

The Health Outcomes of Travel Tool (HOTT) provides an assessment of the impacts of air pollution, accidents and noise. The first of its kind in the public sector it will help NHS organisations make the wider business case for, and track the impacts of, their travel and transport strategies and initiatives. This might include switching to electric vehicles to cut pollution and save money, using technology to reduce patient and staff travel and costs or running staff engagement programmes to encourage active travel – cutting congestion, parking issues and boosting health. 

The tool uses publically available data to build a baseline for all NHS Trusts (including Ambulance providers), and for all CCG and primary care activity within each CCG boundary. The tool also provides national and regional analysis.
