Hi Charlee,
Thank you for your assistance to get these particular questions formally logged.
As discussed whilst the temporal length of the record has an importance my main question was around how are users being notified of that temporal length for the organisation/s they are submitting a query too?
Even if every organisation eventually submits their entire record for query there will still be an asymmetry across the country in the timespan of that record.
The other aspect is how will the user be notified when there is a “loss of connection” to a given organisation so that there is no return of data for a given query? In relation to that specific scenario there will be many organisations that are receiving a query that will have have no record for the patient and the query return would identify that but that is different to a lack of return to the query especially if it is from an organisation that has a record for that patient.
I appreciate that the presentation of these scenarios may vary between commercial supplier but general guidance and a setting of expectations would seem useful following discussion.
