First, it seems nearly impossible to evaluate individually whether the choice made by every HCW to enter the medical profession was informed. The only way to do that would be laboriously to ask each HCW whether they were informed when they decided on the health care profession. Even then, irrespective of whether the person's answer to this question reflects the truth, the only thing that could be learned from such a broad and extensive interrogation would be the individual's perception, not their actual knowledge. By extension, we could not question the participants' level of knowledge in this study, but rather how they perceive their level of knowledge. Because it is futile to seek objectivity in people's perceptions, it would not be sound to use those perceptions to determine whether the HCW's choice was informed, and thus whether they have taken on the duty to treat. And if these perceptions are regarded as subjective, as they should be, then it would be very difficult to develop a set of standard criteria that could be used to establish whether a HCW has been informed. This would also complicate efforts to reach a consensus on forming criteria by which various levels of risk could be defined universally. Unfortunately, such difficulties can only hamper efforts to protect the right of every patient to receive the best treatment available.
