Parachute use to prevent death and major trauma related to gravitational challenge: systematic
review of randomised controlled trials.
Smith GC, Pell JP.
Department of Obstetrics and Gynaecology, Cambridge University, Cambridge CB2 2QQ. <Email withheld>
OBJECTIVES: To determine whether parachutes are effective in preventing major trauma related to
gravitational challenge. DESIGN: Systematic review of randomised controlled trials. DATA SOURCES:
Medline, Web of Science, Embase, and the Cochrane Library databases; appropriate internet sites and
citation lists. STUDY SELECTION: Studies showing the effects of using a parachute during free fall.
MAIN OUTCOME MEASURE: Death or major trauma, defined as an injury severity score > 15. RESULTS: We
were unable to identify any randomised controlled trials of parachute intervention. CONCLUSIONS: As
with many interventions intended to prevent ill health, the effectiveness of parachutes has not been
subjected to rigorous evaluation by using randomised controlled trials. Advocates of evidence based
medicine have criticised the adoption of interventions evaluated by using only observational data.
We think that everyone might benefit if the most radical protagonists of evidence based medicine
organised and participated in a double blind, randomised, placebo controlled, crossover trial of the
parachute.
