Figure 9.24: Potential activity flows for options based on Blue Light proxy travel time to next
nearest hospital 16
The numbers highlighted in blue indicate those sites that would receive more than 20% of
the activity of a hospital that was no longer offering major hospital services. For example, if
Hillingdon was not designated a major hospital, then 71% of its activity would move to
Ealing.
The numbers show the relationship between:
Ealing and West Middlesex:
o With between 41%-52% of activity transferring between the two sites
(respectively), should one of them not be a major hospital.
Hammersmith and St Mary’s:
o Where between 59%-62% of activity would move between the two sites
(respectively) should one of them not provide services
Charing Cross and Chelsea & Westminster:
o Where between 43%-57% of activity would move between the two sites
(respectively) should one of them not provide services.
This analysis was also completed for private car travel times, as shown in Figure 9.25.
16 TfL HSTAT travel times data.
