Are these elective/audition rotation at programs where you want to go to for residency?
I agree with splik that if these are througout your 4th year and not away rotations, then doing other specialty rotations is helpful because this is one of your last times to do so. This is particularly true in specialties with lots of overlap in psychiatry.
I loved my rotations in endocrinology, rheumatology, gastroenterology, neurosurgery, neuroradiology, inpatient renal, child neurology, and EKG lab. I did not enjoy my rotation in neuropathology, inpatient cardiology, pulmonology/allergy/immunology, ophthalmology, infectious disease, and dermatology.
I thought my elective in PM&R was all right but perhaps my rotation was too intervention heavy (lots of muscle ultrasound and fluoroscopic injections for pain) and perhaps being in the TBI or spinal cord injury clinic would have been better. I also didn't particularly enjoy anesthesia or ICU.
Wish I would have done more sleep medicine and neurology subspecialties (dementia, epilepsy, movement disorders, neuroimmunology, headache clinic).
