If there is no longer a problem, then only continued monitoring is needed. If the problem behavior continues, a careful assessment needs to be made as soon as possible. The chance of problem issues slipping through undetected is minimized. The judicious use of quality feedback and close follow-up is invaluable. Sometimes a significant problem can arise despite the best efforts and intentions of the preceptor and the school.
Preceptors often see having a problem during a rotation as a personal defeat or failure.
Nothing could be further from the truth. Course directors know that there will be an occasional difficult situation and are prepared to assist preceptors. Seek help early, and discuss your concerns with someone who will understand. Avoid the temptation to say, Well, I ll just stick this out. There are only a couple of weeks left.
