Growing errors from a certain employee keep occuring. What are the responsibilities as an administrative medical professional in this situation?

The fact that one is dealing in a medical office makes the
error paramount. The standard applied in instances such as this is the so-called
"reasonable person" standard. What does a reasonable person do? Does one ignore the
error? Discipline the employee? Notify other parties? It boils down primarily to common
sense. The one thing that should NOT be done is to ignore the situation. To do so would
constitute actionable negligence. If the employee demonstrates a propensity to make
mistakes, then it is a reasonable assumption that it will occur again. Ones
responsibility then is to take the necessary steps to prevent the re-occurence of this
type situation by whatever means is necessary. Lawyers being lawyers, they will go for
the "deep pocket" if injury occurs. Do not allow the situation to
continue.
