I have a bad feeling that they will be greatly frowned upon, but I just wanted to ask.
I'm currently a 2nd year and I'm on a medication where I'm required to make an appointment with my doctor once a month so I can have some blood-testing done and pick up some more medication from him.
Is this going to be feasible during 3rd year?
I think you'll be fine. These appointments won't cause true "absences," but rather an hour or two away from the action. You should schedule the appointments for the mid-to-late afternoon. Then, mention in the simplest way possible to your resident (or attending if there isn't a resident) that you have a doctor's appointment for blood work. If they say no,
then go to your clerkship director.
What residents and staff don't like are students who schedule these appointments for 8am, or somehow disappear for 5 hours for such an appointment, because it shows poor insight, and possibly some lazy or manipulative intent.
Calling in sick is a whole other beast. The rule of thumb is that you
go to work unless you are actively throwing up or can't leave the bathroom for more than 5-10 minutes due to diarrhea. Smaller ailments with requests for absence will likely draw negative attention. Colds, migraines, etc will get you very little sympathy.
This calloused approach to sick days is the result of the resident system, where one house officer's absence leads to a large amount of work being transferred to someone else's shoulders. Most hard workers decide to "grin and bear it" when they feel sort of sick. They then expect the same out of their med students, who are training to do the same.
The histrionic outcry from students when this has been discussed in the past is "I darest not step into the hospital, lest I
spread germs to my patients!" The simple response to this is that, first of all,
we don't believe your intentions are so pure, and second of all, if they are, then
wear a mask, and some gloves, and wash your hands. Your patients will be just fine.
In my experience as a med student, those people calling in sick were usually just hungover, and couldn't get up at 5am. But my point is that it doesn't matter whether your reason for calling in sick is legitimate or not....it will be interpreted as weak and lazy.
Welcome to the unfair world of medicine.
