Healthlink's core remit is to provide a messaging service that allows patient information to be securely transferred between Hospitals and Medical Practitioners.

Patient information is generated on the source hospital system and transferred to and from our servers using secure network connections. Users log in to the HealthlinkOnline website (Supported browsers: Microsoft Edge v84 and later, Google Chrome v84 and later and Firefox v78 and later) with a unique username, password, PIN and digital client certificate to verify identity. The application is also accessible via web service calls, meaning the accredited Practice Management Systems can integrate patient information automatically without opening the website. Our service calls are also used to generate referral messages from within the Practice Management Systems which are sent on to the hospital via Healthlink. Message files are formatted in HL7 which is an internationally recognised standard for exchanging information between healthcare applications. Healthlink is fully compliant with the HIQA National GP messaging Standards. Any vendor wishing to exchange messages with Healthlink should adhere to these standards.

About Us

Healthlink is the National Health Messaging broker and provides a web-based messaging service which allows the secure transmission of clinical patient information between Hospitals, Health Care Agencies and Medical Practitioners. Healthlink is funded by the HSE and all our services are free of charge to GPs. Healthlink is part of the Access to Information & Health Identifiers Programme under the Office of the CIO. The two teams have come together to realise the vision of enabling timely access to health information when and where it is needed.

Patient Confidentiality:

One aspect of our user support includes following up on patient reports, e.g. test results that have not been sent electronically. If you need to send patient identifiable information to the Healthlink support team you must use your Healthmail account. Healthmail is an email service that allows GPs and their practice staff to send and receive clinical patient information in a secure manner. Healthlink is securely connected to Healthmail so all mail between the two domains is encrypted by default.
