Anesthesiology Focus for Operating Room Efficiency
Anesthesiology may be a sleeper in healthcare, in a manner of speaking. While not traditionally regarded among the top service lines, anesthesiology programs are a direct link to a hospital's biggest moneymaker: surgery in the operating rooms. Hospitals are homing in on anesthesia programs to buttress their ORs and improve coordination with patients to reduce delays.

You might like to take a look at www.ortimes.org. It's about OR productivity with lots of graphs, numbers, and logic.
Great article-hitting all the key success factors but one: Alignment should also talk about alignment of the hospital's goals with the financial arrangement with the Anesthesia group(s). If they are independent, their incentives may not be such that they are willing/interested in changing their practices. I've even seen employed An. groups or those under contracts financially incentivized in such a manner that goals weren't aligned.
