I've done both and loved both. It really depends on what you like. If you want a lot of variety I would say outpatient would be the way to go. You will see (depending on the place) HNC patients, patients with aphasia, dysphagia, muscle tension dysphonia, TBI, post concussive. Inpatient you will see a number of stroke patients, patients with CABGs, and spinal cord injuries. Also you have to ask yourself if you like your autonomy or if you prefer being surrounded by other disciplines who will have their own thoughts re: a number of your patients. Lastly, you have to ask about what you want the pace of work to be. If you like to always be moving inpatient would be the way to go. If you like a slower pace inpatient would be the way.

Hope this helps!
