“Parachuting for Charity: Is It worth the Money? A 5-Year Audit of Parachute Injuries in Tayside and the Cost to the NHS”, C. T. Lee, P. Williams, W. A. Hadden1999-05 (ethics, sociology)⁠:

All parachute injuries from two local parachute centres over a 5-year period were analysed.

Of 174 patients with injuries of varying severity, 94% were first-time charity-parachutists. The injury rate in charity-parachutists was 11% at an average cost of £3,751 per casualty. 63% of casualties who were charity-parachutists required hospital admission, representing a serious injury rate of 7%, at an average cost of £5,781 per patient. The amount raised per person for charity was £30. Each pound raised for charity cost the NHS £13.75 in return.

Parachuting for charity costs more money than it raises, carries a high risk of serious personal injury and places a substantial burden on health resources.
