Implementation

• Chronic Health is stored as a set of options in CCMDB.mdb
• when sent for import into TMSX the chronic health score is translated into yes or no
• the fields were made into a pick list of 9 items that belong to one of the 5 APACHE II CH categories because Medicine wanted to use both APACHE II and SAPS II on Medicine patients; SAPS II and APACHE II scored these same items differently
