The Mass-DAC exceptional risk criteria were developed by a committee of Massachusetts interventionalists to identify patients who were considered to have an exceptionally high risk of mortality that could not be adequately identified using clinical elements collected in the ACC-NCDR data collection tool or included in the Mass-DAC criteria for compassionate use. PCI cases submitted as exceptional risk have to meet the following criteria:
- Extremely high risk features not captured by current risk adjustment covariates; or
- The PCI was the only or best option for improving their chances of survival.
All PCI cases submitted as exceptional risk require additional documentation and are reviewed
by annually by the exceptional risk committee.
The last full update to the criteria occurred in January 2011 with minor syntactical updates done in March 2012. The criteria details, committee protocols, and a series of cases studies are available as pdf file downloads below.
