This query/response is designed for interaction between a client system and an MPI (Master Person Index). The query consists of a set of demographic and/or visit attribute values for a person, and the response is the list of candidates considered by the MPI to match that set.
Each returned person, specified by a PID segment and by a PV1 segment containing information about the current visit, can also have an optional QRI - Query Response Instance segment containing information about the quality of the match.

Following is an example of a Q25/K25 query/response pair of messages. First is the query:

This query is asking for a list of persons matching the name SMITH who are recorded as being in Room 389. Candidates with a match level above 80 using the algorithm Matchware version 1.2 should be returned. The returned records should include identifiers for assigning authority METRO HOSPITAL. The RCP segment specifies that the number of matches should be limited to 20. Here is a sample response:

One candidate was returned. Notice the 1 at the end of the QAK segment signifying the number of matches. The group of segments includes a PID, PV1, and QRI segment; the QRI segment gives a confidence factor for the candidate.
