2 Haemostasis Registry VTE Cohort Study A registry to collect information about the use of rFVIIa in Australia and New Zealand Department of Epidemiology and Preventive Medicine

3 transfusionoutcomes research collaborative Department of Epidemiology and Preventive Medicine

4 A partnership between Monash University and the Blood Service Aim: To improve understanding of blood product usage and the influence of transfusion practice on patient outcomes Established 2008 Department of Epidemiology and Preventive Medicine TTP Registry NAIT Registry Aplastic Anaemia Registry

5 TTP, NAIT, Aplastic Anaemia: Why Registries? Uncommon diseases even major centres encounter few cases associated with significant morbidity and mortality difficult to establish optimal management significant variation in practice disease rarity hampers definitive studies (eg clinical trials)

6 TTP, NAIT, Aplastic Anaemia: Why Registries? Registries collect common experience allow recognition of patterns in care and outcome are hypothesis generating provide baseline data and platform for further studies

7 Thrombotic Thrombocytopenic Purpura (TTP) Registry Estimate approx hospitals in Australia treating TTP 100 cases per year Steering Committee Shlomo Cohney (chair) Paul Cannell Claire Davies Sunelle Engelbrecht Danny Hsu Zoe McQuilten Stephen Opat Louise Phillips David Roxby Erica Wood

8 NZ *Auckland Progress 31 Hospitals participating 32 cases to date Plans to extend registry to include aHUS VIC ALF AUS Geelong MMC Northern RMH St Vincent’s *Western TAS LGH RHH ACT *TCH NSW Concord *Liverpool Nepean PWH RNS RPA St Vincent’s *Westmead Wollongong QLD *Gold Coast *PAH RBWH *Townsville SA FMC QEH *RAH WA Fremantle RPH *SCGH Thrombotic Thrombocytopenic Purpura (TTP) Registry *ethics or site governance in process

9 Neonatal Alloimmune Thrombocytopenia (NAIT) Registry Estimate approx 25 hospitals in Australia treating NAIT <50 cases per year Steering Committee Helen Savoia (chair) Stephen Cole Mark Davies Rhonda Holdsworth Zoe McQuilten Louise Phillips Shelly Rowland Ben Saxon Bronwyn Williams Erica Wood

10 VIC Mercy MMC RCH RWH TAS RHH ACT TCH NSW *CHW *John Hunter Nepean *RHW RNS RPA *Westmead Wollongong QLD Mater Mother’s RBWH *RCHQ SA FMC WCH WA KEMH RPH Progress 21 Hospitals participating 11 cases to date also collecting retrospective cases *ethics or site governance in process Neonatal Alloimmune Thrombocytopenia (NAIT) Registry

11 Aplastic Anaemia Registry few clinicians with a specific interest in aplastic anaemia but potentially treated at all major metropolitan hospitals including children’s and some private estimate approx 100 cases per year Current Status forming Steering Committee developing data dictionary talking to funders (Genzyme & Alexion) expect “go live” late 2011

12 TTP Registry NAIT Registry Aplastic Anaemia Registry Early Coagulopathy of Trauma

13 Early Coagulopathy of Trauma Project Lead: Dr Dev Mitra, PhD Student & Emergency Physician Markers of coagulopathy in trauma patients? – common tests and less-common tests When does coagulopathy establish? – coagulopathy testing at scene of trauma Can we recognise it when it begins? – possible use of point-of-care testing equipment Can we intervene in the pre-hospital phase? – potential trial of early treatment either on arrival at ED or in pre-hospital

14 TTP Registry NAIT Registry Aplastic Anaemia Registry Early Coagulopathy of Trauma Pandemic Project

15 Australia’s blood supply in a major disaster or pandemic: How will we meet clinical demand? Department of Epidemiology and Preventive Medicine Transfusion Outcomes Research Collaborative Epidemiological Modelling Unit Infectious Diseases Unit

16 Pandemic project Limited data on recipients of blood products indication for transfusion urgency of requirement consequences of with-holding transfusion RBC, platelets and FFP No robust model of clinical demand impact of pandemic on clinical demand impact of pandemic or other disaster on supply how can demand be made to match supply? Planning for circumstances of shortage need a model to assist in developing or evaluating the impact of different triage approaches if blood supply limited

17 Modelling Demand for Blood Transfusions Transfusion Required Non-urgent (> 1 wk) Transfusion Required Semi-urgent (24 hrs - 1 wk) Transfusion Required Urgent ( hrs) Transfusion Required Acute (<1 hr) Not requiring transfusion Under “normal” circumstances:

18 Modelling Demand for Blood Transfusions Transfusion Required Non-urgent (> 1 wk) Transfusion Required Semi-urgent (24 hrs - 1 wk) Transfusion Required Urgent ( hrs) Transfusion Required Acute (<1 hr) Not requiring transfusion Death If no blood is available: 4 possible outcomes at each urgency level Outcomes more or less likely depending on disease Identified 14 disease groups Total of 56 disease/urgency combinations Estimate likelihood of the outcomes for each Use this information with volume of transfusion in each category to create model

19 Modelling Demand for Blood Transfusions Transfusion Required Non-urgent (> 1 wk) Transfusion Required Semi-urgent (24 hrs - 1 wk) Transfusion Required Urgent ( hrs) Transfusion Required Acute (<1 hr) Not requiring transfusion Death Once model is developed: able to project impact of different strategies of restriction eg with-hold transfusion from particular disease group or urgency level - how much is saved? model impact of pandemic on demand eg likely increase in demand from group (such as more ECMO) due to effect of pandemic

21 MTR Demographic Information Clinical Coding ICD-10 AR-DRG Transfusion History Laboratory Results ?Pharmacy National or Local Databases/ Registries ANZICS ASCTS Trauma all patients receiving ≥5 units RBC in 4 hours any time in hospital admission any context of bleeding (trauma, surgical, obstetric, etc) all data collection electronic

22 MTR Demographic Information Clinical Coding ICD-10 AR-DRG Transfusion History Laboratory Results ?Pharmacy National or Local Databases/ Registries ANZICS ASCTS Trauma Progress recent scoping exercise identified 8 pilot hospital sites in four states negotiating details, ethics, costs involved expect “go live” September 2011 hope to expand to more hospitals in 2012
