Meeting Etiquette• Remember: If you are not speaking, keep your

phone on mute• Do not put your phone on hold – if you need to

take a call, hang up and dial in again when finished with your other call– Hold = Elevator Music = very frustrated speakers and

participants

• This meeting, like all of our meeting is being recorded– Another reason to keep your phone on mute when not

speaking

• Feel free to use the “Chat” feature for questions, comments or any items you would like the moderator or participants to know.

NOTE: This meeting is being recorded and will be posted on the DAF

Query Analysis• Query Analysis: Determine the constructs that

we want to allow in Data Element Based queries.

• Limitations on Number of Data Elements to be included in the formation of a single query

– A Query can be constructed using multiple data elements• For e.g “Get patients between ages 16 and 65, with diabetes and

having a hbA1C lab result of > 7%”.

10

Query Analysis Cont’d• Comparators allowed in Query Specifications

• Numbers, Dates>, >=, <=, and <

• Strings–From FHIR: Search is case-insensitive and accent-insensitive. May match just the start of a string. String parameters may contain spaces.

–Exact matches also required

• Quantities–Values which are numeric –Units which are strings

• Coded Concepts–May be used to search through the text, displayname, code and code/codesystem

11

Query Analysis Cont’d

• Concept of Named Queries ?

–Similar to Document Queries with ability to vary the parameters for the queries.

12

Query Analysis Cont’d

• Logical Operators

–AND

–OR

–NOT

13

Query Analysis Cont’d

• Missing Information– Allow queries on missing information or

presence of information ?

• Specifying the data elements to be included in response– Should we allow for this in the queries ? – Responders may choose not to include all

requested elements

14

Query Result Analysis• Query Result Analysis: Determine the

constructs that we want to allow in Data Element Based queries.

• Limitations on Number of Data Elements to be included in the formation of a single query

– A Query Result can be constructed using multiple data elements

• For e.g: Query Results may contain Patient Demographics, Problems and Meds all as a result of a single query

15

Query Result Analysis• Do Query Results need to allow for

– Summaries ?

– Paging ?

– Counts ?

16

Query Result Analysis• Other aspects that we are missing ?

17

Candidate Standards• SOAP Query Stack

– IHE QED and IHE CM profiles

• RESTful Query Stack– FHIR DSTU

• No existing profiles

• Other standards for specific parts of the queries/results– HQMF V2 for Queries and QRDA category III for Results – HL7 vMR Data Model

• HL7v2 Stack – QBP/RSP messages

• Implementation Languages in Use– SQL, Xquery,

Questions
