HEMOVIGILANCE SYSTEMS
Pierre Robillard1,2 MD

2
What is hemovigilance
• A set of surveillance procedures on undesirable events/effects along the whole transfusion chain– Systematic data collection– Regular analyses of data– Interpretation of results– Dissemination of results
3
What is hemovigilance
• Objectives
– Prevent occurrence or recurrence of those undesirable events/effects
– Establish priorities for intervention– Evaluate preventive measures
• Products– Blood components (mainly)– Plasma derivatives (in some countries)
• In many countries under pharmacovigilance (drug post-market surveillance)
Scope of national hemovigilance
• Donations– Donor safety
• Undesirable effects of donations in donors
– Blood safety• Surveillance of ID markers in donors• Surveillance of donor exclusion factors
Scope of national hemovigilance
• Surveillance of the transfusion process
– Errors at blood center– Errors at the hospital– Traceability
Scope of national hemovigilance
• Recipients– Identification of transfusion-transmitted
infections• Traceback and lookback activities• Matching recipient database with reportable disease databases
Scope of national hemovigilance
• Recipients– Surveillance of adverse transfusion events
• Serious only• All reactions
– Identification of long term effects of transfusion• Matching databases
– Recipient with death registry– Recipient with tumour registry– Recipient with hospital discharge database
Scope of national hemovigilance
• Blood utilization– Patterns of use of blood components
• Type of components• Diagnosis of recipients• Procedures performed on recipients
– Appropriateness of use?
Scope of national hemovigilance

TYPES OF GOVERNANCE FOR HEMOVIGILANCE SYSTEMS
• Blood regulator– France, Switzerland, Germany
• Blood manufacturer– Singapore, Japan, South Africa, Ireland
• Professional organizations– Netherlands (TRIP), UK (SHOT)
• Public Health– Canada (TTISS)
• Public-private partnership– USA Biovigilance Network (CDC+AABB)
Requirements for establishing a national hemovigilance system
• Hospital– Personnel dedicated to blood safety
• Transfusion safety officer• Blood bank director• Chief technologist
– Role• Investigation and reporting of transfusion reactions and
errors• Training• Oversee implementation of preventive measures
Requirements for establishing haemovigilance
• Hospital
– Transfusion committee• Multidisciplinary• Review transfusion reactions• Propose and evaluate preventive actions• Guidelines for appropriate utiization
• National level– Hospitals committed to participate – STANDARDIZATION
• Data elements to be collected• DEFINITIONS of those data elements
– Centralized body for analysis• Expertise in transfusion medicine• Expertise in surveillance• Regular feedback to those who report
– Establish governance for the system
Requirements for establishing a haemovigilance system
• National level– Data validation is crucial
• Cannot assume that definitions were followed• Needed for meaningful comparisons between
institutions• Maybe unrealistic for all reactions but necessary for
serious ones– Can be achieved through a validation committee
• Single• Reaction specific

The Canadian Transfusion Transmitted Injuries Surveillance System
(TTISS)
21
Background In collaboration with Canadian
Provinces/Territories, Health Canada Regulatory and Canadian Blood Manufacturers, the Public Health Agency of Canada (PHAC) implemented a voluntary Transfusion Transmitted Injuries Surveillance System (TTISS) to monitor adverse transfusion events (ATEs)

National TTISS Working Group• Membership
All provinces/territories representedBlood manufacturersHealth Canada regulators
• Terms of Reference Identify and address issues related to a national
surveillance program to determine the risk of transmission of infections and injuries by blood transfusions
Recommend future directions, quality, efficacy and effectiveness of the TTISS as a national surveillance program
24
National Data Review Group • Membership
Members are selected for their individual medical/scientific expertise in the fields of: public health infectious diseasesepidemiology transfusion medicine
Ex-officio representatives are from PHAC, Health Canada, Canadian Blood Services and Héma-Québec
• Terms of Reference Reviewing and evaluating surveillance based epidemiological data
concerning the risk of transmission of infections and injuries through blood, blood components and plasma derivatives
Develop research questions and hypotheses for investigation purposes
Identify signals or unusual events that should be further investigated
25
Methods• Data on Adverse Events is collected at
the hospitals/sites •Most sites voluntarily report the data to a
provincial/territorial office •Few sites report directly to the Public
Health Agency of Canada• Non-nominal data are transferred as per
the provincial/federal TTISS agreement to the Public Health Agency of Canada

Transfusion Errors Surveillance System (TESS)
Pilot Project – Data 2005-7
36
Background• TESS is an abbreviated error tracking
system designed for non-academic use
implement a tool for systematic capture of errors, including near-misses
Coding scheme comparable to what is now being used in USA biovigilance network
37
Methods• Actual event vs. Near-miss
• Severity

Online transfusion history Online transfusion history In the period May 2003- Nov. 2005
All Québec hospitals were progressively computerized with the same blood bank software
A query tool was addedEach hospital can query the BB database of all other
hospitals to see if patient is present If so information will appear on screen:
Blood group, irregular antibodies Previous transfusions Previous transfusion reactions, special requirements
This information can be compared with current info or test results on patients
Information cannot be saved and disappear from screen upon leaving the query tool.

Purpose of Database
Informationsharing
Surveillance, Monitoring
Analysing data
Potential Uses• Benchmarking for countries• Risk assessment
67
What data?• General information
– On the country’s haemovigilance system and coverage
• Denominators general - for donors/ donations and major categories of products
• Denominators specific - for products
• Adverse events in donors related to donation
• Errors – IBCT
• Adverse reactions in patients that are possibly, probably,
or definitely associated with transfusion
68
Pilot Studies• Data have been collected in 3 rounds• 2006-7, 2008, 2009• 18 countries have participated in at least one round
69
General information, 2009
• 14 haemovigilance systems – 13 national– 1 regional
• In terms of total blood supply: - half have 100% coverage and two >90%- three more are in the range 80-89%
70
Volume of data, 2009
• 14,553 total adverse reactions

CONCLUSION• Hemovigilance is now an integral part
of a quality system in transfusion• Hemovigilance covers donors,
processes and recipients• Hemovigilance helps identify priorities
for transfusion safety and monitors effects of preventive measures
• Hemovigilance works
