QM Department Structure

I'm looking for information regarding how QM departments are structured. We've had a change in personnel and have an opportunity to restructure our department. Currently there are 2 of us who are responsible for infection control, Core Measure abstraction and data entry, mortality review, return to surgery review, blood utilization review, MD peer review, MHA data collection. Regulatory body and insurance carrier data collection are part of the department responsibilities too. Then there are the other day to day occurrences to follow up on, etc. We are looking to hire the right type of personnel. We are a 250 bed hospital. I know some places use more nurses, others use some clerical and data entry personnel along with nurses. If you have a good system, please share your ideas. I'm also interested in hearing what doesn't work.
Thanks.
