I might be able to help you as I work in large physician practice as clinical manager. Physician practice is soooo much different than working as a hospital manager. The best book I've read is "Good to Great" by Jim Collins. Might not seem like it applies to heatlhcare but it's great for understanding the "on the bus or off the bus" concept. It's a hard core look at leadership in business and that's really what's needed in the physician practice. Good Luck as it can be difficult to manage if you don't have supportive leadership over you. The other is Clincial 5S for healthcare by Akio Takahara. If you can more toward the LEAN process, it will help your organization.
