In such circumstances, it is hard to guarantee that a doctor will not give a patient a treatment as a pretext for research or even ignore the patient's rights entirely. For example, a doctor might continue an experiment in spite of a patient's bad reaction to it.
此時，醫師是否會「假借治療之名而行研究之實」，甚至罔顧病人權益，例如在出現不良反應時，仍繼續試驗？實在難以保證。
