Make the Past serve your Future

  1. 1. Cincom Make the Past serve your Future: Glorp and ActiveRecord Andreas Hiltner, Dirk Verleysen, Niall Ross, Cincom 16 August 2011 Version 0.1 ESUG – 23ep2011 - 0
  2. 2. A typical episode of „House‟ First scene: ―Nothing to worry about Mrs Bit-Part. Your baby has a mild case of PolysyllabicMedicalTerm. A short course of ChemoBabble will clear it up in a trice.‖ But soon enough: ―I don‘t understand it - the fever is worse.‖ And by half-way through: ―Our diagnosis must be wrong. Phone the lab to test for DeadlyDiseaseSyndrome.‖ And in the lab: ―The baby is dying. We have to find more of the sample fast – enough to run the A.C.R.O.N.Y.M. test.‖ Later in the lab: ―Its EvenDeadlierDiseaseSyndrome! Tell the hospital to Administer 30cc‘s of Sesquipedalia immediately!!‖ And finally: ―It‘s OK Mrs Bit-Part – the fever is going down now‖ Closing CreditsCincom ESUG – 23aug2011 - 1
  3. 3. Reality can be more like this than you‟d think• Genetics Lab: regional (central lab for many hospitals) — Cytogenetics (chromosomes) — Molecular DNA analysis• Immunophenotyping: also central lab for many hospitals — cell surface markers — some molecular DNA analysis• Haematology lab: one in each hospital — full blood count — morphology on sample• Histo-Pathology lab: one per hospital + central re-referral — Morphology in situ (of bone marrow trefine or other biopsy) — immuno-histochemistry: cell surface markers in situCincom ESUG – 23aug2011 - 2
  4. 4. Blood cancer diagnosis• Patient “presents”: consultant takes sample — not an easy or enjoyable procedure; sample may be sparse / poor / … – e.g. haemodilution, a.k.a ―I can‘t analyse this bloody sample‖  — bone marrow aspirate, bone marrow trefine, full blood count, etc.• Sample divided for Labs based on initial diagnosis — labs have no warning (sample can be delayed or misdirected)• Each lab enters sample into distinct bespoke system — Genetics‘ was sub-sub-contracted to Rumanians – Table and column names ‗unintuitive‘. Poor fit to domain . – ―Every time we make a change it breaks!‖ — The other Labs‘ systems are in the same state — None of these systems can be retired for years• Labs analyse: clinician‟s diagnosis is right – or not !Cincom ESUG – 23aug2011 - 3
  5. 5. “or not” can be time-wasting or serious (1)Examples of time-wasting:• “Myelodysplasia is in the differential – include Genetics.” — Histo-pathology do the morphology: ―No, it‘s just IDT.‖ – Idiopathic: we have not a clue what is causing it – Thrombocytic : it is to do with platelets – Purpura: the symptom is a rash — Genetics could skip their test - if only they knew the Histo-path result• “Acute leukaemia?” – no, just iron deficiency anaemia – would save much time and money if Genetics knew Blood resultBUT no connection between Lab systems or to path lab reception (sample dispatch) either Just wasting lab time can be serious for another patientCincom ESUG – 23aug2011 - 4
  6. 6. “or not” can be time-wasting or serious (2)Examples of serious:• (for elderly patient): “Its IDT – skip Genetics.” — Blood lab: ―No, it‘s MDS !‖ — Genetics need to find a Lab with spare sample• (for infant) invasive procedure + general anaethetic, then: – ―Its IDT – skip Genetics.‖ (rarer now – it is so critical) – Haemodilution — (and then), ―No, it could be acute lymphoblastic leukemia !‖ – if so, sample cells die fast - get to spare sample fast ! – another 2 days to culture, then time to analyse – you have 7 days !How is spare sample found? By random phoning around.Cincom ESUG – 23aug2011 - 5
  7. 7. Requirement: something old, something new• Web app: consultant / path lab reception enter — Sample dispatch data — Initial diagnosis• App puts sample data in — its RDB — Lab-systems‘ RDBs• Labs process sample: more data in lab systems• App presents that data — results and result tracking — Multi-disciplinary team use system to create their reports — Labs use system for emergencies, time-waste avoidance, etc.Cincom ESUG – 23aug2011 - 6
  8. 8. Process• ObjectStudio Mapping Tool — Read the schema (who needs documentation!) and understand it – Display tables and relationships – Create classes, view data• ObjectStudio Modeling Tool — Import classes, show diagram• Some Essential Fixes — Rename some classes: doctors do not read Rumanian  — Consultants subclass: DiagnosingConsultant, ReferringConsultant – Be ready for upcoming organisational changes — New descriptor: subclass, convert to sibling refactor – Generate DB for web app Write data between new and old DBs (not how real system will do it!)Cincom ESUG – 23aug2011 - 7
