The information contained on this website was extracted from the Maryland Department of Health and Mental Hygiene, the Health Services Cost Review Commission, and a survey that is conducted annually by the Maryland Health Care Commission (MHCC). MHCC surveys all ambulatory surgery providers in the state to develop the MHCC Freestanding Ambulatory Surgery Data Base. The data on the website was collected in 2005 for the 2004 calendar year. Please note that because of data collection cycles, some names, addresses and specialties may have changed. Please check with the ambulatory surgery facility to ensure the accuracy of the information.

There are differences in the data available for freestanding ambulatory surgery facilities and hospital-based facilities. For example, the numbers of practicing specialties are listed for freestanding facilities; however, these data are not currently displayed on the website for hospital-based facilities. The MHCC anticipates adding these data in the future. In addition, the operating and procedure rooms listed for freestanding ambulatory surgery facilities are used solely for outpatient surgery, however, a hospital may use an operating and procedure room for both inpatient and outpatient cases. Hospitals may also have more total operating rooms than listed on the report since hospitals are only required to report the number of operating and procedure rooms used for ambulatory surgery.

It should be noted that this report reflects the number of cases performed in the year, not the number of procedures. One case may involve multiple procedures. Additionally, the volume of cases listed for the year may not be inclusive of the entire year if the facility was not open for the entire year.
