Abstract: If the patient’s disease is the equivalent cause of the damage in disputes over medical damage compensation, the medical party will only be responsible for the corresponding proportion of damage caused by its negligence through the analogical application of contributory negligence. The causative potency rule may be applied only if each related factor constitutes the cause of damage. Causative potency should not be used to replace the analysis of the elements of causation, nor should it be confused with proportional causation. Causative potency is the quantitative analysis of the effect of a cause on the fact of damage and is purely used to solve the burden-sharing based on the construction of multi-causative damage.
