The document discusses the complexity of healthcare communication and information sharing. It notes that more healthcare information is electronic now and distributed across multiple organizations. Healthcare is also more regulated, requiring more data sharing and reuse of information. The document uses the example of GP2GP, a system allowing electronic transfer of patient records between general practitioners. It argues that healthcare information standards are needed to reduce costs and risks of data sharing, and to support interoperability between different healthcare IT systems and tools. The document recommends tactics like having a clear business case for interoperability initiatives and taking an incremental, standards-based approach.
