Agenda

2. loinc submission review

Minutes

We reviewed submission rows 52-67.

We identified two principles:

1. LOINC (reference) terms may and many cases should differ from NEMSIS (interface) terms.
2. The LOINC question should not introduce concepts not present in the NEMSIS question.
   1. E.g., if the NEMSIS question does not specify a method, neither should the LOINC code.
   2. Or, if a LOINC code has a time aspect "Enctr^frst": that's either wrong or it's not something we know.
   3. Oxygen saturation: probably capillary, but not necessarily. Use the broadest system (Bld), not arterial (BldA) or capillary (BldC).
   4. This is true even when we know the habitual or probable method in the field, and, less strongly, if we don't currently know of any other method.

and a question:

1. We assume that "example units" means that other units are acceptable.
   1. For instance, if the example units for "end tidal CO2" are "mmHg," you could substitute cmH2O.
   2. Could you also substitute other measures of pressure, e.g., pascal, bars, atm?
   3. Could you substitute other dimensions that measure the same clinical fact, e.g., %?

Issues

Issue	Description	Resolution	Status
Run Report Scope	Event model contains hospital information: is this 'run report' information?	No, per Clay, 2/3/11	Closed
SD question 1	Need OIDs, URN	URN: make one up, per B Dolin. OIDs: request a 'root' document OID and write our extensions, for later import into the repository.	closed
SD question 2	harmonizing sections with IHE, HITSP, etc.	Use CCD as appropriate, or downstream templates as necessary. No registry or process exists.	closed
MDHT question 1	approach for many questions: model question as separate template, create new association, use Type to assign template	confirmed by Sean	closed
Coding strength	Are all RR codes CNE, except, presumably, ICD/RxNorm sets?		open
