In CHIROPRACTIC / MEDICAL MALPRACTICE CAUSATION AND THE DEGENERATIVE SPINE, medical malpractice expert witness Richard K. Skala, DC, writes:
Proving or disproving Legal Medical Causation is based on testimony by expert witnesses regarding the “proximate” cause of negligence to a standard of reasonable medical probability. The plaintiff bears the burden of its expert being able to conclude to this standard that indeed negligence occurred and thus damage ensued. The defense expert bears the opposite burden of concluding to the same standard that there was no cause of negligence and thus no damage.
Regardless of which side of the argument an expert speaks to, their conclusions must be persuasive in terms of causation. The standard of reasonable medical probability essentially means that “it is more probable than not” that a chiropractor did or did not do something negligent during the course of treating a patient that resulted or caused some degree of damage. Experts on both sides of the arguments must be able to demonstrate that the conclusions they pose as “within reasonable medical probability” have enough evidentiary weight to convince a reasonable person that their conclusions are in fact correct.
