Volume of Common Procedures

One element that is associated with good care is hospital volume. While researchers are still trying to understand the exact relationship between volume and quality, studies have found that surgical teams with experience - that is, routinely performing a sufficient number of cases - have better results.

Looking at hospital volume over time can also provide you with some useful information about how practice patterns have changed over the years with the growth of new technology and new ways of doing procedures.

Below are the number of times BIDMC has performed certain procedures in recent years. For information about BIDMC surgeon volume, click on this link to the state's hospital cost and quality website:

1BIDMC Volume Data has been prepared from BIDMC administrative databases, using procedure definitions adapted from those outlined in the Commonwealth of Massachusetts, Office of Health and Human Services (EOHHS) Health Care Quality and Cost Information at These definitions reflect inpatient hospitalizations between October 1st  through the following September 30th of the fiscal year indicated in the column heading.

2Percutaneous Coronary Intervention (PCI) hospitalization volumes include a broader set of procedure codes than those outlined in the Department of Public Health Volume Inclusion definitions. BIDMC has included PCI procedures performed in both inpatient and outpatient settings to reflect the full level of activity between October 1st and September 30th of the fiscal year indicated in the column heading.
