Nineteen secure messaging and clinical information system vendors have successfully fulfilled the requirements of the Australian Digital Health Agency's secure messaging industry offer, with practice management system vendors MediRecords and Intrahealth, and patient administration system and billing specialist Direct Control, the latest to complete the work.

The vendors expect to begin rolling out the interoperability capability in the next versions of their software, allowing for enhanced searching across multiple secure messaging services by using a federated provider directory.

However, a number of big names in the industry are not taking part in the offer, including GP practice management system vendors MedicalDirector and Global Health, which also markets the ReferralNet secure messaging service, and market leading secure messaging vendor HealthLink, despite all taking part in two proof-of-concept trials in 2018.
