Appendix 2: National estimates

Slipping on ice

Nationally during 2009/10 we estimate that there were 1,662 emergency admissions to a hospital bed as a result of slipping on ice, and a total number of NCIs due to slipping on ice of 39555.

A.
No. of survey admissions due to slipped on ice / B. Proportion of all reported admissions / C.
Total no slipped on ice incidents / D.
Ratio of admission: slipped on ice incident / E.
National (English) admissions (NCIs,
all ages, all causes 2008/09) / F.
National (English) number of NCI admissions due to slipped on ice
(E*17.6%) / Total number of slipped on ice incidents in England during 2008/09
1662x 23.8
Slipped on ice / 9 / 17.6% / 214 / 1: 23.8 / 9,447 / 1,662 / 39,555

All non-collision incidents

Slipped on ice incidents are 26% (est.) of all non-collision incidents

Total non-collision incidents p.a. in England = (39,555/26)*100=152,134.

Severity of injury / Proportion from survey (%) / National number (est)
Killed or seriously injured / 6.2% / 9,432
(The actual number of emergency admissions due to NCIs in England in 2008/09 was 9,882. This estimate is within 4.6% of the actual number)
Minor injury / 26.5% / 40,315
No injury requiring professional help (5,6,and 7 see table above) / 67.1% / 103,538

Applying (+/- 4.6) to total NCIs in England gives a range of between 142,701 and 158,523 incidents.

Appendix 3: Who is responsible for non-collision cycling incidents?

Responsibility / Number / Proportion
Rider / 180 / 8.8%
Not rider / 41 / 22.2%
Shared / 440 / 68.9%
