NICE reports on promoting walking and cycling

As part of its public health stream, NICE has commissioned work on interventions to promote cycling and walking for recreational and travel purposes.  Their recommendations are now open to consultation.

ScHARR led the commissioned research and produced three reports:

Whilst contributing to the two reviews, HEDS led the modeling work and developed a de novo model - the ScHARR Walking and Cycling Model version 1.0.  It is built around three components:
  • The relationship between levels of walking and cycling, and overall physically activity. This allows direct evidence from studies of the effect of interventions on levels of walking and cycling to be converted into estimated changes on overall physical activity.
  • The relationship between physical activity and relative risk of mortality.  This allows transformation of physical activity level changes into life expectancy, numbers of deaths and quality adjusted life-years.
  • The relationship between levels of walking and cycling, and travel, especially driving distance but also driving time and numbers of trips. This allows estimation of the effects of interventions that increase levels of walking and cycling on reduced kilometres driven and hence reduced congestion, pollution, and greenhouse gas emissions.

At the risk of oversimplifying months of hard work and a 186 page report, the modelling findings for those interventions identified by NICE ranged from £300 per QALY for TravelSmart to around £3,000 per QALY for a short-term 4-week pedometer intervention.  Many other scenarios were also evaluated.
