Looking for London crash victims

Hello. We are defining a crash to include single vehicle collisions e.g. bike and pothole. In terms of severity, we are going by the STATS19 definition, but equally recognise there's room for subjectivity.
Slight - An injury of a minor character such as a sprain (including neck whiplash
injury), bruise or cut which are not judged to be severe, or slight shock requiring
roadside attention. This definition includes injuries not requiring medical treatment.
Serious - An injury for which a person is detained in hospital as an “in-patient”, or
any of the following injuries whether or not they are detained in hospital: fractures,
concussion, internal injuries, crushings, burns (excluding friction burns), severe cuts,
severe general shock requiring medical treatment and injuries causing death 30 or
more days after the accident.

We've included life-changing injury in there as a category which would fall under STATS19 definition of 'serious injury', as these types of injuries should be investigated by the Serious Collisions Investigation Unit (who investigate fatalities and the most serious cases) - so interesting for us to understand this as part of the survey.

So to summarise - do not need a hospital visit to count as being slightly injured.

Thanks!
