PCHAlliance publishes and promotes the Continua Design Guidelines, the only open implementation framework for authentic, end-to-end interoperability of personal connected health devices and systems. 

The Continua Design Guidelines are based on common international standards defined by recognized standards development organizations, and are built on four key principles:

  1. Authentic interoperability – connectivity requiring minimal effort on the part of the user
  2. Open source development model – the Continua Design Guidelines are universally accessible, non-proprietary and not for profit
  3. Flexibility – designed to provide maximum choice for developers and end users (healthcare buyers, individual clinicians and consumers)
  4. Wisdom of the market – the market in aggregate has more wisdom than any individual stakeholder; thus the Continua Design Guidelines are developed through a consensus process

Valuable tools and resources support product certification via the Continua Design Guidelines, including: the Continua Enabling Software Library (CESL) and test tool development, representing millions of dollars worth of software development created by Continua to enable complete end-to-end functionality. PCHAlliance members have access to Continua Certified Experts (CCE), pre-market interoperability testing, Technical Operations Leads and brand support for Continua Certified products. PCHAlliance also participates in a series of events around the world to connect members with buyers, as well as Plugfests, Summits and an online Product Showcase highlighting Continua Certified products and services.

The Continua Council is the Continua Design Guidelines governing body, boasting today's most dynamic, forward-thinking and successful organizations: AT&T, Samsung, Intel, Orange, Philips, Roche Diagnostics, Eli Lilly, ResMed and CSIRO.

PCHAlliance non-members and members are invited to comment on the most current version of the Continua Design Guidelines.  All comments, from members of the PCHAlliance and from non-members alike, will be reviewed and addressed in the next round of development.

Continua Design Guidelines & Approved Use Cases Now Available

The 2015 Continua Design Guidelines contain references to the standards and specifications that Continua selected for ensuring interoperability of devices. The 2015 Continua Design Guidelines are now available for download. Approved use cases are also available.

Continua Use Cases, 2006-2014

Continua use cases are approved by member ballot and incorporated into its Design Guidelines according to procedures set out in Continua’s Lifecycle Process. Once approved for development, a use case is generally divided into one or more “work items”, discrete increments of capability, for development as Guidelines. In complex cases, some work Items may be completed and published as Guidelines while others remain in development.

Once approved at ballot, a use case normally remains open to development for a period of 4 years, after which it becomes ‘closed’ unless there is a case put forward for an extension.

The following documents provide indexed, searchable access to all balloted use cases, within their corresponding timelines. For questions about a particular use case or Continua’s process for approving and developing use cases into guidelines, please contact

The Continua Design Guidelines are available free of charge.

Continua device certification does not mean or imply that the device is legally marketable in any country; certification only assures that devices communicate in a standard fashion per Personal Connected Health Alliance certification requirements and Guidelines. Refer to the device manufacturer or country Health Authority for specific details associated to device marketability or usage.
