Recently, with the increasing of the medical malpractice, the Doctor-Patient relationship becomes more and more difficult. Unfortunately, the testimony of medical expert witness has not been so reliable and the accused doctor's right of confrontation is not well protected, either. Although Medical Doctors are all excellent, their abilities also have some limitations. In addition, it is very difficult to avoid all the risks of medical practice because of the complexity of human body and the limitation of medical knowledge. It is not only too strict but also unreasonable to require the doctor assuming all the responsibilities, including the civil compensation for damage, disciplinary disposition, even the criminal penalty, for all kinds of medical malpractices. When such requirements are too strict, it will let the doctor refuse to treat certain patients who are difficult to be cured and the only result is the regress of healthcare quality. Definitely, it is not the expectation of patients. When the medical malpractice arises, the only method to resolve the malpractice dispute and mitigate the difficulty of Doctor-Patient relationship is to determine that who should be responsible after parties' debate, basing on the scientific testimony of medical expert witness and the protection of accused doctor's right of confrontation.
