In a way, the main job of an ER doctor is to get the patient stable enough to survive leaving the ER for admission--or well enough to be sent home. The work is difficult and challenging, so no one really adds to their workload with after-hours attention to those being treated elsewhere, such as in hospital rooms or ICUs. You should say, however, that you do take an interest in these 'temporary' patients of yours and like to follow up on certain cases. You just can't go wrong stating this.
