Business Rules are logical requirements for completing an ePCR based on various field selections. For example, information must be entered in the Patient Disposition/Patient Demographics fields unless the field is marked as Canceled or No Patient Found. These logical requirements may already exist in NEMSIS guidelines or as department protocols. However, you can create Business Rules in CDX for any additional departmental needs.
For states using CDX, rules must be generated as a Schematron file, an XML representation of the rules, ifor the system to use them in validating uploaded run records. State administrators can also upload an external Schematron file to be used in the validation process.
