Number / Who / Summary / Status/Disposition
12 / Doug Pratt / Passing “reason for data missing” code in CWE.1 in place of code is dangerous practice; for example, “NA” for not asked could be confused with Sodium. / Discussion was tabled in Orlando. Doug will make motion on teleconference for cautionary language in 2.6, address more formally in 2.7.
Open Needs Motion
24 / Peter Scholz / Balloter wants user defined tables allowed for CNE. / User defined tables deliberately left out for CNE. Want ruled out of scope

25 / Peter Scholz / Balloter wants all table types for CWE / Was accepted in Orlando
Closed by Vote in Orlando
32 / Frank Oemig / Add imported table to list of CNE allowable sources. / Persuasive and voted so in Orlando.
Closed by Vote in Orlando
33 / Frank Oemig / Statement of disappointment that CNE definition has ambiguities. / Ruled out of scope, needs to be addressed in 2.7.
Closed by Vote in Orlando
44 / Frank Oemig / Treated same as 32. / Closed by Vote in Orlando
45 / Frank Oemig / Treated same as 33. / Closed by Vote in Orlando

1) MMS Grieve/Julian to resolve Negative ballot #12 for Version 2.6:

Add the following warning to section 2.A.13.1, after table 353:

CAUTION! Sites with systems that can send “Data Missing” status values in CWE.1 must ensure the following:

  • The sending system properly values CWE.3 (coding system) in such cases to “HL7 0353” to indicate that the value in CWE.1 is a meta-value for data missing, as opposed to an actual value, and
  • All receiving systems properly recognize such circumstances by interrogation of CWE.3, and therefore not mistake the meta-value in CWE.1 for an actual value.

Failure to do so can result in a very dangerous situation: if the sending system were to send the meta-value “NA” – “not applicable” from table 353 to a system that did not interrogate CWE.3 for this scenario, and the receiver recorded this “value” as “NA” in its database, then this code might be interpreted as “Sodium” (by the clinician, or if it matched a master file entry for the field). Depending on what this field represents (coded result, drug to be administered), patient safety may be compromised. For this reason this method of communicating data missing will be revisited in subsequent versions of the HL7 standard.

Motion was approved 4-0-1

MMS Grieve/Julian to declare CNE/CWE done for v 2.6 Motion was approved 5-0-0

6. v2 ballot reconciliation, (max 20 minutes)

Will defer pending additional work

7. Master File / Registry ballot reconciliation (last 20 minutes of the call)

Prepared motions will be posted the list prior to the call.

R-1. Motion to find line item 23 to be Non Persuasive. The MFMI domain documents generic versions of static and dynamic models common to all domains that use these wrappers. CQ has no knowledge of what domains will end up using these wrappers for master file/registry applications. Therefore the models described in the MFMI domain will always be generic in nature. The D-MIM walkthru shows the relevant subsets of the static models during the various parts of the dynamic scenario. CQ would welcome domain specific additional story boards which it could include in the domain, either created by PA or by the balloter.

MMS Grieve/McCaslin to defer until Rene is present. Motion was approved 5-0-0

R-2: Motion related to the discovered item documented in line 24: Motion to "Add the following to the MFM_RM700720 and MFMI_RM700700 R-MIMs: a PriorRegisteredRole class with minimal attributes (including id), linked by an optional Subject participation to the existing PriorRegistration act. Change the ID attribute of the RegistrationProcess Act classes to be required instead of mandatory."

MMS Grieve/Julian to accept R-2.(Motion was approved 4-0-1):

R-3: Motion to accept the typos and minor textual corrections as suggested by line items 2,3,4,5,6,15,17 and 22.

MMS Julian/Stewart to accept R-3. (Motion was approved 5-0-0)

R-4: Motion to find line items 8 and 9 to be Considered, and respond to the question as follows: "Yes, the statement should be more generic. CQ will replace occurrences of Notification by Interaction."

MMS Grieve/McCaslin to accept R-4. (Motion was approved 5-0-0)

R-5: Motion to find line item 14 to be persuasive, and to replace the existing paragraph by "In version 2, a given master file message concerns only a single master file (e.g. patients only). The provision of a record-level event code (and requested activation date) in the MFE segment allows a single message to contain several types of changes (events, e.g. update, delete) to that file. The Version 3 model allows for changes to multiple master files within 1 interaction (e.g. a change to the person master file as well as to a location master file). Record-level changes are supported by means of the RegistrationProcess class which may be related to multiple records. The closest equivalent of the RegistrationProcess class is the MFE segment."

MMS Julian/Stewart to accept R-5. (Motion was approved 5-0-0)

R-6: Motion "to find line-tem 18 Not Related, as this is not a ballot comment." (note that this isn't a pubs issue. HQ has been requested to add IM to the ballot database, they have indicated they'll do so.

MMS Grieve/Stewart to accept R-6. (Motion was approved 4-0-1)

R-7: Motion to Accept line item 20 as it is part of the ballot cleanup which wasn't done after the last ballot cycle.

MMS Grieve/Stewart to accept R-7. (Motion was approved 4-0-1)

R-8: Motion to Accept line item 21 as it is part of the ballot cleanup which wasn't done after the last ballot cycle.

MMS Julian/Grieve to accept R-8. (Motion was approved 5-0-0)

Deferred until after harmonization this next week.

Line item 19 is pending the outcome of the Feb 18 Harmonization call.
