To be honest as long as you are doing something, its better than nothing... You do not necessarily have to do somethign in the health care field (I work as a research analyst at a chemical engineering company and I'm sure that won't count against me b/c its not health related). However, with research experience try something like clinical research or a research associate. I'm not sure where you are from, I'm from the bay area. So we have a bunch of research assistant positions at UCSF and Stanford....so try looking for universities near by and getting research assistant position or clinical research postions. But anything you do stands out as long as you can explain how you grew as a person from that experience...good luck
