TitleH&I Haematopoietic Stem Cell Transplantation (Recipients & Donors) Ask At Order Entry
Realmus
Authorityhl7
Description**Ask At Order Entry Questions** for NHS Blood and Transplant's (NHSBT) national **H&I Haematopoietic Stem Cell Transplantation (Recipients & Donors)** request form (`FRM1010`, form "3C" in NHSBT's own numbering) - see [NHSBT's published form](https://nhsbtdbe.blob.core.windows.net/umbraco-assets-corp/31364/3c-haematopoietic-stem-cell-transplantation-recipients-donors.pdf) and [Histocompatibility and Immunogenetics](HistocompatibilityAndImmunogenetics.html#ask-at-order-entry-questions). Unlike the sibling [HLA Tests - Transplant](Questionnaire-HLATestsTransplantAskAtOrderEntry.html) and [Chimerism Test Additional Ask At Order Entry Questions](Questionnaire-ChimerismTestAdditionalAskAtOrderQuestions.html) - both extracted from a live Hive/Histotrac `ORM^O01` order - this Questionnaire is modelled directly from NHSBT's own **paper request form**, since no live system message for it has been sourced. It is **not** `derivedFrom`/`extends` [Genomic Test Order](Questionnaire-GenomicTestOrder.html): this form is submitted directly to NHSBT (a national body, not NW GLH/MFT), so its own Patient/Requester fields are restored here rather than assumed available from the common core order form - the same reason [HRD and Tumour BRCA](Questionnaire-HRDTumourBRCAAskAtOrderEntry.html) restores its own Patient/ Healthcare Professional groups. **A separate form must be completed for each individual** - the same physical form is used both for the patient being transplanted and for each family member/potential donor being tested, distinguished only by which "Complete for..." section is filled in. This is modelled below as a `Role` choice with `enableWhen`-conditioned items, since FHIR Questionnaire has no native "delete as applicable" concept. The **HLA Typing**, **Chimerism Analysis** and **HLA Specific Antibody Testing** checkboxes on this form overlap with (but are not identical to) the test-selection lists already modelled as `Patient Test(s)` on the sibling HLA/Chimerism Questionnaires above - this form uses NHSBT's own coarser Class I/Class I+II and Total/Lineage-specific categories rather than Hive's finer-grained checklist, so they are modelled here as their own items rather than reusing those `answerOption` lists. **No NHSBT-published FHIR/LOINC/SNOMED binding was found** for any of this form's own fields (Role, CMV Status, Time to transplant, HLA Typing scope, Chimerism Analysis type) - all coded locally against the `NWGMSA` CodeSystem, the same approach taken for the sibling H&I Questionnaires above. Field mappings below are this IG's own best-effort candidates, not confirmed against a live order message.
