Modeling
| # | Question | Answer | Status |
|---|---|---|---|
| 1 | How do we distinguish a patient who has no prehospital section because there was no EMS engagement from a patient who who has no prehospital section because the data is missing? | The prehospital section can contain a null flavor of "not applicable" ("NA") meaning that there was no such event (i.e., the patient was a walk-in) or of "unknown" ("UNK") meaning that the information is not available. | Resolved |
| 2 | How are identifiers assigned? |
|
Resolved |
| 3 | Are time zones required on time stamps? | Yes | Resolved |
| 4 | Are time intervals inclusive or exclusive? | The abstract data types specification stipulates no default assumption, but the IVL pattern does support the Boolean properties lowClosed and highClosed that allow the user to specify the boundary type. | Resolved |
| 5 | confirm validation can include constraint identifier in error message | Grant reports no, but NTDS identifiers will be provided as they are today | closed |
| 6 | Do we need a code system for actEncounterCode (FLD) | Yes; VALUE SET: ActEncounterCode (2.16.840.1.113883.1.11.13955) | Closed |
| 7 | Should we specify section title in IG (content, not just presence) | Yes; "should" for title. Text is up to implementer. | Closed |
| 8 | Put last modified date in version rather than create? | See #2. | Closed |
| 9 | May need to break Transport Mode into two templates | One template, two paths; make sure DI can read this. | Resolved |
| 10 | Value sets without enumerated members are not listed in appendix: Trifolia issue | Listing can be forced. | Closed. |
| 11 | Missing LOINCs | Most received; some questions on missing items, and address codes requested. AAAM question seems close to resolution; still awaiting closure from LOINC. (currently have an SCT code for predot question code; need LOINC. Also need LOINC severity code & answers. Somehow we got the body regions done already.) | Open |
| 12 | Need question codes for coded address elements | "ANSI FIPS" now in GNIS: use GNIS pending ACS approval | closed |
| 13 | Missing circ values for ED | Hospital & ED; we've put it in the more general place. Stet. | Closed |
| 14 | P_05: field encounter does not end when unit leaves scene. Do we need to break this out? | Yes; done | Closed |
| 15 | Ensure SCT coded elements use correct OID (system = 2.16.840.1.113883.6.96) (page 21, 56, 74) | Closed | |
| 16 | Gender has incorrect system name (page 12, 60) | HL7 Administrative Gender, not SCT | Closed |
| 17 | style question: should we have a template for prehospital encounter entry, or should those contents go in the section template? No. | closed | |
| 18 | style question: should qualifier questions (supplemental O2, resp assistance) be closer to the vitals they modify? | No; those two elements are re-used | closed |
| 19 | add text explaining author & custodian, when they might be different | Open | |
| 20 | Use LOINC displayName values | Open | |
| 21 | Heart rate: change 8893-0 to 8867-4 | Closed | |
| 22 | Hospital GCS needs qualifier (not field) | May use same template, with optional qualifier. 55285-1 Glasgow coma score special circumstances. 10/28: the structure handles the requirement, but the names are confusing. Might it be better to have "Glasgow score without qualifier" and "Glasgow score with qualifier" (rather than "Nervous System Observation Organizer Entry" and "Nervous System Observation Organizer")? | Open |
| 23 | Question: constrain time to TS, rather than prohibiting center & width? At least remove constraints. | Open | |
| 24 | Injury address is coded, just like patient address. Reuse (& rename) | consider later using LOINC 69447-1 for injury address; 18581-9 for patient. | Open |
| 25 | Rename "Value Set: Abbreviated Injury Scale Severity 2.16.840.1.113883.3.2898.11.7" to "Injury Kind" or "Abbreviated Injury Scale Injury Kind" | It's not a severity | Open |
| 26 | Either replace SCT code with TBD at 30020 or make sure to remember to replace it | Open | |
| 27 | Add zip code to coded address structure | Open |
Terminology
| # | Question | Answer | Status |
|---|---|---|---|
| 1 | (age units) Minutes in HL7 not in NTDS; Weeks in HL7 not in NTDS | I don't recall deciding to add these, so we should probably remove those two.
NEMSIS has minutes but not weeks. |
Closed |
| 2 | Industry incorrect | I don't know why LOINC assigned some codes and not others. We should use the NAICS top-level values, not the LOINC answer codes. | Closed |
| 3 | Any long list incomplete (e.g. industry) | can we set up Trifolia for this, or do we need to publish a spreadsheet (or use PHIN VADS or VSAC). No: we need to publish some other way. | Closed |
| 4 | Code for “Other Race” is in NTDS but not in HL7 | We propose to use "OTH" flavor of null | Closed |
| 5 | LA17105-0 - Patient Chemically paralyzed – In HL7 is not a NTDS code | Included based on harmonization with NEMSIS | Closed |
| 6 | LA17388-2 No airbag present – Not an NTDS code and currently the represented NA – null flavor case. This is the only case where I found a NTDS Null coded into a LOINC code. | Included based on harmonization with NEMSIS. And "not present" isn't really a null. | Closed |
| 7 | Protective Devices: Code Distinction issue – The lap and shoulder belt codes now contain the ‘Only’ description which is not accurate to the existing NTDS codes. | Included based on harmonization with NEMSIS | Closed |
| 8 | Child seat breakdown now in protective devices, no distinct field/element? | Included based on harmonization with NEMSIS | Closed |
| 9 | No code for “Airbag Present” | Based on harmonization with NEMSIS--Airbag status contains this information | Closed |
| 10 | No code for ‘Other’ protective devices | We propose to use "OTH" flavor of null | Closed |
| 11 | Need country codes | Use VS 2.16.840.1.113883.3.88.12.80.63 (HITSP), system 1.0.3166.2.2.2, name Country Codes, OR HL7 V3 VS 2.16.840.1.113883.3.88.12.80.63, same system oid, name Country2? use the latter. | Closed |
| 12 | Need State codes | Use VS 2.16.840.1.113883.3.88.12.80.1 (HITSP), system 2.16.840.1.113883.6.92, name FIPS 5-2 (State) (available at http://www.census.gov/geo/reference/ansi_statetables.html) | Closed |
| 13 | Need County codes | Use VS 2.16.840.1.114222.4.11.829 "PHVS_County_FIPS_6-4"; system OID 2.16.840.1.113883.6.93 (available at http://www.census.gov/geo/reference/codes/cou.html) | Closed |
| 14 | Need City codes | Use VS GNIS civil and populated places, new OID 2.16.840.1.113883.3.2898.11.28, system 2.16.840.1.113883.6.245 GNIS, available at http://geonames.usgs.gov/domestic/download_data.htm | Closed |
