Haemovigilance data for 2011-12 and 2012-13
The NBA National Haemovigilance Program and HAC continue to support the development and alignment of state level reporting systems with the recommended national haemovigilance dataset and Australian National Haemovigilance Data Dictionary.
This report includes validated adverse event data from state level systems, including the New South Wales (NSW) Health Incident Information Management System (IIMS), Victoria's (VIC) Blood Matters Serious Transfusion Incident Reporting (STIR) program, Queensland's (QLD) Incidents in Transfusion program (QiiT) and South Australia's (SA) Health Safety Learning System. STIR also supports haemovigilance in Tasmania (TAS), the Australian Capital Territory (ACT) and the Northern Territory (NT). NSW has improved its haemovigilance reporting capacity since the last report and provided detailed and validated adverse event data (such as imputability and outcome severity data) for this report. QiiT provided 2011–12 data only due to the system being decommissioned in 2013. Western Australia (WA) is the only jurisdiction not contributing to the national dataset for this report.
There were 2,251 adverse events reported to the National Haemovigilance Program from 2008–09 to 2012–13. The number of reports increased from 294 in 2008–09 to 615 in 2011–12, mainly due to the improved adverse event reporting from NSW, however this dropped in 2012-13 to 429 due to QLD not providing any reports for that year. The most frequently reported adverse events are febrile non-haemolytic transfusion reactions (FNHTR) and severe allergic reactions, representing 52.6% and 25.4% of all reports respectively. The first three confirmed cases of post‑transfusion purpura (PTP) were reported in 2009–10 and 2010–11.

| PTP | - | - | - | 0.0% |
| Total number of reports | 615 | 429 | 1,044 | 100.0% |
Notes
- All TTIs were bacterial infections and these were reported cases but not necessarily confirmed.
- Limited adverse event data available for NSW for 2008–09 and 2009–10. NSW only provided detailed data (such as blood products, outcome severity and imputability score) for 2011–12 and 2012–13.
- Adverse event data unavailable for ACT and NT for 2008–09, and QLD for 2012–13.
- Adverse event data unavailable for WA.
