The central problem in determining the proper compensation for an injury is the
speculative nature of the claimant’s future medical and economic needs.
Traditional insurance schemes pay medical costs as they are incurred. If the
claimant requires treatment five years after the injury, that claim is paid by the
insurer at the time the care is rendered. This creates an open-ended
obligation, but it obviates the need to speculate on the future needs of the
claimant when evaluating the claim.
