| 4 | Anesthesia CRG - history, purpose, current and recent activities | Andrew Norton summarised development of medical terminologies, with a focus on Anaesthesia and the development of bodies such as the APSF, their Data Dictionary Task Force, IOTA, IHTSDO and SNOMED. The importance of record keeping as a contributor to safety systems and research was noted - these activities are underpinned by high-quality classification systems. The area of interest of the Anesthesia CRG reflects the breadth of anaesthesia - including pain medicine, critical care and perioperative medicine. We works with colleages within SNOMED (Nursing) and outside it (HL7, ISO, Government bodies). Current areas of focus include work on inclusion of ISO 19223 and representation of clinical scales such as the Glasgow Coma Scale (GCS). The group has contributed to representation of terms relating to COVID-19, and review of existing terms relating to fluid therapy.. Work contributed by the group is submitted for inclusion in SNOMED. New members are welcome to join the group. | |
| 5 | HL7 Anesthesia SIG and relevance to SNOMED CT | Martin Hurrell | Martin Hurrell described recent work of the HL7 Anesthesia Working Group (WG). HL7 is established in common use and develops standards for the exchange of electronic health information. The Anesthesia WG is currently focusing on a model (Domain Analysis Model, DAM) to describe the concepts, events and conduct of anesthesia, using a semantic model so that meaning of data can be preserved between models/ systems/ sites/ countries. The DAM will be the basis of a FHIR implementation guide, so that the terms developed may be incorporated in future systems. The group works with the Anesthesia CRG, such as reviewing existing terms and "binding" these to elements of the DAM. It also works with individual experts, specialist societies, ISO (esp the 19223 group), ASA EMIT and SCATA. Other groups include the ASA, AAGBI, NHS Scotland and the American VA. The model is built following analysis of specimen cases/ storyboards. The content of these is analysed and expressed in formal structural terms. Entities (people, devices, medications, etc.) and Acts (admisistration, measurement, etc.) are fundamental building blocks. Sufficient detailed description is considered to enable representation of the realities encountered in clinical practice. The Anesthesia WG and the Devices WG are due to merge in the near future, as the areas have significant overlap. |
| 6 | Questions and discussion | All | Steven Dain led discussion of the HL7 DAM ventilation modes. A number of modes (18) are listed as examples and are identified as commonly used and practical, but the theoretical number of possible combinations would be unmanageable. Normal Jones noted that these are categorised into 4 useful groups in the HL7 document, and suggested that this would be a useful structure to follow. Review of SNOMED ventilation modes to be updated and consistent with these is worthwhile. Ongoing work will include review of ventilatory adjuncts (e.g. ACAP), repiratory terminology and definition of respiratory equipment terminology (e.g. Endotracheal Tube). SNOMED will need comprehensive review for completion of definitions for existing terms. |
| 7 | Current progress of modelling assessment scales | Modelling of assessment scales such as GCS is an ongoing interest of the group. The Clinical Frailty Score was discussed by Andrew Norton , noting the generic difficulty of representing a system which has sub-scores (e.g. GCS has 3 component scales). See the CRGs discussion pages. | |
