Custom breakdowns can be added to the breakdownResultOutputTypes property in shrine.conf. A new custom breakdown can be added by creating a new property inside breakdownResultOutputTypes and providing a description and category for the new breakdown. Each property name must match a breakdown name available in i2b2's QT_BREAKDOWN_PATH table. Please note that the SHRINE user role in i2b2 must have permission to access the breakdown. Below is an example of three custom breakdown configurations, PATIENT_TOP20MEDS_XML, PATIENT_TOP20DIAG_XML, PATIENT_CHARLSON_XML, and PATIENT_NIH_ENROLLMENT_XML.
