Comment (by nateapathy): Following up on the discussion from 8.11.15 GPC Dev call: {{{ c) how cost effective to switch to SCHILS terms from GPC? i) Dan : feedback from Cerner folks? (not here today). I’ll try to catch up with them ii) PR/UTSW: vote to not switch, prefer to maybe map between the two, but our GPC terms cover more granular and we’d lose that if we switch iii) DC/KUMS: maybe adopt SCHILS terms for things we haven’t settled for GPC yet, e.g. use SCHILS for procedures but not diagnoses iv) RW/KUMC: obesity & adaptable trials drive timeline (for Sept.) to implement new CDM terms }}} The most significant improvement that the SCILHS ontology provides is that it aligns with best practices for i2b2 design and comes with CDM creation scripts using the "PCORNET_CD" field. The most obvious design improvements are how demographics are stored in the database and how modifiers are structured. The transition from the Cerner standard i2b2 ontology to the SCILHS ontology was relatively straightforward, largely thanks to the use of best-practice designs for i2b2. For example, storing patient demographic data as observations in the OBSERVATION_FACT table is not a standard design practice, and the SCILHS ontology resolves this. As for granularity, it can always be added back in later versions, and I would like to see us pursue that with SCILHS as a partner rather than creating a hybrid which will undoubtedly be more convoluted for the end user. It also gives us significant ability to leverage other groups' work, and decreases the distance between "proprietary" i2b2 design and something moderately resembling a standard, at least across i2b2-using PCORnet CDRNs. It would behoove us to tack as closely as possible to any repeatable standards emerging from other groups, as it only increases our economies of scale. My understanding from comment3 on this ticket is that we would be adopting the SCILHS ontology as a group - I did not think the decision was still up for debate. I also recognize that other groups are focusing on the Obesity terms and ADAPTABLE terms. As CMH will not be participating in ADAPTABLE, we've had cycles to focus on the SCILHS effort that other teams won't have for some time. -- Ticket URL: <http://informatics.gpcnetwork.org/trac/Project/ticket/191#comment:7> gpc-informatics <http://informatics.gpcnetwork.org/> Greater Plains Network - Informatics _______________________________________________ Gpc-dev mailing list Gpc-dev@listserv.kumc.edu http://listserv.kumc.edu/mailman/listinfo/gpc-dev
