http://xw2k.nist.gov/healthcare/docs/170.304.i_ExchangeClinicalinfoPatientSummaryRecordAmb_v1.1.pdf This is the test for exchanging clinical summaries. The EHR has to be able to read a CCD and a CCR, and to be able to create one of these. Synapse can now create a CCR that validates correctly. At present the minimum data set which is demographics, problem list, allergies, results and medications is done. The others are not necessary but will be added in due course.
