IHN member haemovigilance systems (HVS): Information about methods/situation for better understanding of their outputs

GENERAL - HAEMOVIGILANCE (HV) SYSTEM

Is there a HV system at blood establishment/regional/national level in your country?
(If national) how many years ago was a national haemovigilance system established?
Select year or select option (number of years before date of filling in form)
(If national) When the national haemovigilance system first started, did it collect data on recipient haemovigilance, donor haemovigilance or both?

Please answer the questions below about the national HV system. If there is no national HV system but there is a regional HV system, answer about the regional system.

Is the HV system managed by national (or regional) authority, blood service, professional expert body, other?
Select one option
What was (were) the reason(s) for setting up the HV system?
Select (one or more).
Is reporting
Select one option (please describe)
Do the reporters send the reports on paper? on an electronic form? directly into a database? or an other method?
Please give details (optional question). Is there a reporting system for medical device (including reagents) problems?
If yes, are HV reports and reports about medical devices (including reagents) system sent to the same authority?
Is there a reporting system for pharmacovigilance?
If yes, are HV reports and pharmacovigilance reports sent to the same authority?

ORGANISATION OF TRANSFUSION SERVICES

In your country, how many blood establishments are there which collect whole blood, red blood cells or platelets by apheresis and/or plasma? (Please include independent blood establishments as well as hospital-based blood establishments which collect blood. Please also include establishments which collect plasma only. Count the organisations; do not count all their collection sites separately)
Which organisation(s) is/are responsible for component selection for individual patients

TRANSFUSION REACTION REPORTING

Does the HV system collect information on recipient adverse reactions (transfusion reactions)?
Do you have standardised definitions for transfusion reactions?
Do you use internationally endorsed definitions (e.g. ISBT-IHN definitions for non-infectious transfusion reaction)?
Please briefly outline all the steps and people involved.
If there is a transfusion reaction, which organisation performs the extra blood testing?
Please describe.
Does the HV system collect only serious reports or all severity levels?
Does the HV system collect all imputability levels including:
Tick each level for Yes; comment at end (optional).
Do you have a panel or committee of experts, or equivalent?
Is the reported type of reaction assigned by the reporting hospital or laboratory or at the level of the HV agency?
Are reports verified (validated) based on accompanying information: all, or all serious cases?
Do you conduct separate analyses for certain patient (sub)groups e.g. pediatric transfusion reactions, multi-transfused patients such as transfusion dependent thalassemia?
Reports relating to (medicinal) SD-plasma* - does the HV system collect information about reactions and/or errors associated with (medicinal) SD-plasma? *SD-plasma=pathogen reduced pooled solvent-detergent treated plasma (e.g. Octaplas®)
Does the HV system collect information about reactions and/or errors associated with use of reinfusion drains, blood warmers, etc
Do you receive reports from clinical staff/transfusion facilities regarding iron overload?

REPORTING OF INCIDENTS AND FAILURES

Does the HV system collect information about errors/incidents?
Are staff able to participate in haemovigilance reporting without fear of being punished?
Is the information in the haemovigilance system protected from use in a disciplinary process, if there is one?
Does the HV system collect information about 'near miss' events or transfusion errors which did not lead to harm?
Are there near miss events that should be reported as serious (e.g. if inappropriate blood/blood components have been issued/distributed for use, even if not used.)
When incidents are reported, does the HV system collect information about findings of incident investigation?
Does the HV system collect information about adverse consequences where transfusion was a) delayed or b) not given although it should have been, because of an error/incident?
In your country, does national level monitoring of appropriateness of transfusions take place, e.g. through Hb levels before / after, INR or platelet counts?
Does the HV system collect information about unnecessary (avoidable) transfusions because of error/incident (e.g. because of wrong Hb)?
Does the HV system collect information about shortages, when stocks of any of the following run out at national or regional level (blood collection bags, test kits for transfusion-transmissible infections, test kits for routine blood grouping, others)?
In your country, do shortages of blood and blood components occur?

DONOR HAEMOVIGILANCE

Does the system collect information on blood donor adverse reactions?
Does the system collect information on errors/incidents associated with blood (component) donation, even if there was no harm? (E.g. misidentification of a donor; apheresis procedure using incorrect IV solution)
Do you utilise standardised definitions for blood donor adverse reactions?
Do you use the ISBT-IHN-AABB definitions for donor complications)? https://www.isbtweb.org/fileadmin/user_upload/Donor_Standard_Definitions_Final_2014.pdf
Has the 2020 severity grading tool for donor adverse reactions been implemented?
Does the HV system collect only serious reports of donor adverse reactions or all severity levels?
Is the imputability of donor adverse reactions reported?
Do you collect:
Tick which imputability levels are collected
Do you have a panel or committee of experts (or equivalent) who review serious DAR?
Select all which apply.
Are abnormal ferritin values or deferrals due to iron deficiency reported?
Does the HV system receive information about donor adverse reactions from all blood establishments including private sector plasma collectors?
Select all which apply.

FEEDBACK AND RECOMMENDATIONS

Is information about the reported transfusion reactions reported publicly, e.g. in an annual report?
Is information about the reported blood donation complications reported publicly, e.g. in an annual report?
Does the HV system make recommendations for improving safety?
Can the HV system issue an alert to the blood bank or clinicians about an important issue, e.g. a serious reaction following an unsafe practice?

SOME FIGURES

Total population of country/region (millions)

Voluntary non-remunerated, replacement, autologous predeposit.
