| # | 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 | Open |
| 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 | Open | |
| 22 | Hospital GCS needs qualifier (not field) | May use same template, with optional qualifier. 55285-1 Glasgow coma score special circumstances | 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 |
