#	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?	Patient (incident) and document: Set ID (event): root = ACS OID + ".4." + facilityID + ".1"; extension = patient ID Document ID (instance or version of document): root = ACS OID + ".4." + facilityID + ".2"; extension = text, unspecified but unique Effective time: last modified date Version number: do not use The Facility Id should be ACS OID + ".4." + facilityID (ACS-assigned 5-digit ID). Patient id within the record target can be the same as the setId	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. Unless & until LOINC/AAAM answer, we use American College of Surgeons National Trauma Data System; 2.16.840.1.113883.3.2898.5.1, codes IS_01, Injury kind and IS_02, Injury severity	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		Closed
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")?	Closed
23	Question: constrain time to TS, rather than prohibiting center & width? At least remove constraints.		closed
24	Injury address is coded, just like patient address. Reuse (& rename)	consider later using LOINC 69447-1 for injury address; 18581-9 for patient.	Closed
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	Closed
26	Either replace SCT code with TBD at 30020 or make sure to remember to replace it		Closed
27	Add zip code to coded address structure		Closed

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
