Healthshare Exchange of Southeastern Pennsylvania (HSX) has implemented an automated care team finder that allows a hospital to find the patient’s primary care doctor using a directory of Direct addresses. The automated care team finder uses the patient’s member identification with his or her healthcare insurer to identify providers involved in the patient’s recent medical care. The identified providers receive C-CDA documents with emergency department and inpatient discharge summaries using Direct Secure Messaging. HSX has sent over 70,000 discharge summaries using this method with 51 percent of these documents sent to providers across health systems.
