This document summarizes feedback from grantees of the HIway Implementation program in Massachusetts. It shows that grantees include various types of healthcare organizations. They intend to use the HIway primarily to send and receive care summaries and referrals. Grantees are measuring outcomes like reduced readmissions and test duplication. While progress is being made, grantees face challenges with vendors, connectivity, and resources. Most are confident in meeting objectives but recognize the work may take more effort and flexibility than initially expected.
