Changing Jobs 12-16 months before MBA

I'm considering applying this coming fall to a August/September 2015 start at a top 10 american MBA program. I'm considering changing jobs in the next 6-10 weeks and am wondering how this would impact my chances of getting into a good program.

I'm currently working at a tier 1.5 management consulting firm and have been working there since I graduated in 2011. I have been promoted once and am expecting another promotion in October. Through several projects, I developed an interest in healthcare and have been pursuing more project work in that area. Unfortunately, while my firm does have a strong healthcare practice, most of our work intersects retail (like pharmacies) or manufacturing/ supply chain and the opportunities to get the kind of work that I am interested in (more on the provider side). Additionally, the firm is going through a bit of culture transformation following a management shakeup and turnover has been exceptionally high this year. Frankly, I'm also just done with traveling Monday-Thursday. These factors have made me consider making a move before applying.

I'm considering moving into healthcare industry and taking up a strategy position in a local hospital network. I have several other job leads, and all of them relate to health in some way. Most of them are title/responsibility upgrades, but likely pay downgrades. I've asked a few people in my network about potential moving (but, as you can imagine, the number of opinions I can get are limited), and have gotten mixed feedback. Some feel it will signal career confusion while others say it will help me broaden my experiences and differentiate me from other management consultants, especially since among MC candidates, I am not an ultra-top performer from a top firm.

Thanks in advance for your input!
