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

Page 3: HEMOVIGILANCE SYSTEMS

3

What is hemovigilance

• Objectives

– Prevent occurrence or recurrence of those undesirable events/effects

– Establish priorities for intervention– Evaluate preventive measures

Page 4: HEMOVIGILANCE SYSTEMS

• Products– Blood components (mainly)– Plasma derivatives (in some countries)

• In many countries under pharmacovigilance (drug post-market surveillance)

Scope of national hemovigilance

Page 5: HEMOVIGILANCE SYSTEMS

• 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

Page 6: HEMOVIGILANCE SYSTEMS

• Surveillance of the transfusion process

– Errors at blood center– Errors at the hospital– Traceability

Scope of national hemovigilance

Page 7: HEMOVIGILANCE SYSTEMS

• Recipients– Identification of transfusion-transmitted

infections• Traceback and lookback activities• Matching recipient database with reportable disease databases

Scope of national hemovigilance

Page 8: HEMOVIGILANCE SYSTEMS

• 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

Page 9: HEMOVIGILANCE SYSTEMS

• Blood utilization– Patterns of use of blood components

• Type of components• Diagnosis of recipients• Procedures performed on recipients

– Appropriateness of use?

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)

Page 11: HEMOVIGILANCE SYSTEMS

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

Page 12: HEMOVIGILANCE SYSTEMS

Requirements for establishing haemovigilance

• Hospital

– Transfusion committee• Multidisciplinary• Review transfusion reactions• Propose and evaluate preventive actions• Guidelines for appropriate utiization

Page 13: HEMOVIGILANCE SYSTEMS

• 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

Page 14: HEMOVIGILANCE SYSTEMS

• 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)

Page 21: HEMOVIGILANCE SYSTEMS

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

Page 24: HEMOVIGILANCE SYSTEMS

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

Page 25: HEMOVIGILANCE SYSTEMS

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

Page 36: HEMOVIGILANCE SYSTEMS

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

Page 37: HEMOVIGILANCE SYSTEMS

37

Methods• Actual event vs. Near-miss

• Severity

Severity DescriptionHigh Potential for serious injury or deathMedium Potential for minor harmLow No realistic potential for harm

Type Description1 Actual – harm2 Actual – no harm3 Near-miss – unplanned recovery4 Near-miss - planned recovery

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.

Analysing data

Potential Uses• Benchmarking for countries• Risk assessment

Page 67: HEMOVIGILANCE SYSTEMS

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

Page 68: HEMOVIGILANCE SYSTEMS

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%

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
