PHMR: Data Model strawman

Filed under:

An outline and invite to meetings for the next steps of the PHMR work.

As you know work has been progressing on defining the next version of the Telehealth Personal Health Monitoring Report message. The message that will carry vital sign data and nurse notes from telehealth service providers systems to other subscribed systems, e.g. GP Systems or Personal Health Records.


We have now reached broad agreement on the types of data that should be carried by the message; see the consolidated feedback report here. This was arrived at after the initial review workshop at Intellect, a number of conference calls and direct input from various organisations.


We now need your involvement to help complete the next phase, agreeing the data model. This starts on Thursday 21st June at 12:30, conference call invite attached. During this call we will present the straw man data model for discussion and feedback. Excerpt at the end of this email.


A follow up call on Thursday 28th June at 12:30, will discuss the feedback and reach agreement on the data model for the next version of the PHMR.


The next milestone is the Release Candidate message specification. To reach this we need your involvement in contributing to, refining and testing the message as it’s developed. Please email me directly to register interest or speak up in one of the conference calls.


Once we have a Release Candidate message specification we will be asking organisations to implement this as a ‘First of Type’.


If you have any questions please do not hesitate to contact me, otherwise I look forward to hearing you on the conference call on the 21st.
