Serious adverse events and serious adverse reactions (SAEARs)
Please see below for a number of frequently asked questions from a specific category. Simply select one of the questions of interest, the answer will then appear below. For the complete list of categories please visit the main FAQs page.
Establishments are required to notify the HTA of serious adverse events (SAEs) or serious adverse reactions (SARs) within 24 hours of discovery. Establishments should take note that a full investigation of an event or reaction is not required for the purposes of initial reporting. The results of a root cause analysis and corrective preventative actions can be submitted as a follow-up report at a later date.
It is the responsibility of the Designated Individual (DI) to notify the HTA of any suspected SAE or SAR. In the DI’s absence this responsibility can be delegated to other designated members of staff; however, the DI retains overall responsibility for ensuring that such notifications and reports are received by the HTA.
If you are a third party providing services to a licensed establishment, or if you purchase material from a licensed establishment, then you should report SAEs and SARs directly to the DI of the establishment you are working with. You should advise the DI that they need to report to the HTA on your behalf.
Please note, systems for reporting SAEs and SARs are not intended to replace existing local reporting requirements.
The HTA is designated the UK competent authority for the purposes of the European Tissues and Cell Directives so far as they relate to tissues and cells. As such, it has a statutory obligation to ensure that systems are in place to report, investigate, and share information about SAEs and SARs. This includes a duty to communicate information about any SAEs or SARs to other relevant persons or bodies such as: persons and establishments carrying out human application activities, other competent authorities and to the European Commission. This allows appropriate action to be taken if tissues or cells need to be withdrawn or control measures are required. In compliance with this requirement, the HTA issues regulatory alerts if it becomes aware of circumstances affecting a number of tissue establishments.
The authority is also required to keep a register of SAEs and SARs and to make this information available to the public in a manner that it considers appropriate. The HTA has included information about SAEs and SARs in the summary of compliance reports for the Human application sector and is currently considering how best to share further learning from the submitted reports with the sector.
A serious adverse event is defined as ‘any untoward occurrence which may be associated with the procurement, testing, processing, storage or distribution of tissue or cells intended for human application and which, in relation to a donor of tissue or cells intended for human application or a recipient of tissue or cells: (a) might lead to the transmission of a communicable disease, to death or life-threatening, disabling or incapacitating conditions, or (b) might result in, or prolong, hospitalisation or morbidity.
A serious adverse reaction is defined as ‘an unintended response, including a communicable disease, in a donor of tissue or cells intended for human application or a recipient of tissue or cells, which may be associated with the procurement or human application of tissue or cells and which is fatal, life-threatening, disabling, incapacitating or which results in, or prolongs, hospitalisation or morbidity.
SAEs and / or SARs can be reported to the HTA via the HTA Portal.

Can anyone at the establishment report to the HTA?
It is ultimately the responsibility of the Designated Individual (DI) to notify the HTA of any suspected serious adverse event or reaction. In the DI’s absence, this responsibility can be delegated to other designated members of staff through the HTA Portal (this process should be supported by a clearly documented procedure outlining such delegated responsibilities).
The initial notification to the HTA should be made within 24 hours of the discovery or determination of the SAE or SAR by the licensed establishment. Third parties and end users should be instructed to report to the licensed establishment within 24 hours of their discovery of SAEs or SARs. Tissue establishments should be able to respond to SAEs and SARs within this time frame inside their normal operational hours.
The establishment should not wait to conduct an investigation prior to reporting to the HTA. There is a separate form on the notification system which allows further follow-up information to be provided once an investigation has been completed.
If a serious adverse event or reaction has implications for other tissue establishments - for example, because of a shared donor - the tissue establishment should also notify those other tissue establishments as appropriate without delay.
Please note, the systems for reporting SAEs and SARs to the HTA are not intended to replace existing local reporting requirements.
A serious adverse event (SAE) can occur at any stage from donation to transplantation. A suspected SAE should be reported to the HTA when one or more of the following applies:
- inappropriate tissues / cells have been distributed for clinical use, even if not used;
- the event could have implications for other patients or donors because of shared practices, services, supplies or donors;
- the event resulted in loss of any irreplaceable autologous tissues or cells or any highly matched (i.e. recipient specific) allogeneic tissues or cells;
- the event resulted in the loss of a significant quantity of unmatched allogeneic tissues or cells.
Examples of reportable SAEs are given at the bottom of this FAQ.
If you are unsure whether an adverse event constitutes an SAE and requires reporting to the HTA, please contact the HTA for further guidance.
Events which are commonly referred to as ‘near misses' should be reported as SAEs if any of the above criteria are met.
Any serious adverse reaction in a living donor which may influence the quality and / or safety of tissues and cells should be reported to the HTA.
Any serious adverse reaction in a recipient observed during and / or after clinical application which may be linked to the quality and / or safety of tissues and cells should be reported to the HTA.
Suspected serious transmitted infections (e.g. bacterial, fungal, viral, prion, parasitic) should always be reported to the HTA.
Examples of reportable serious adverse reactions are given at the bottom of this FAQ.
If you are unsure whether an adverse reaction constitutes an SAR and requires reporting to the HTA, please contact the HTA for further guidance.
When the HTA receives notification of an SAE or SAR, a member of the serious adverse events and reactions (SAEARs) team will review the information provided in the initial report and contact you if further information is required. Establishments are expected to submit a follow-up report once internal investigations have been completed. A member of the SAEARs team may advise if any further actions are required. During the HTA’s review process, we may offer advice and guidance to the reporting establishment, and / or participate in the development of corrective and preventative actions.
The HTA may use the information in SAEARs reports to adjust an establishment's risk rating which could prompt a site visit inspection. If required, the HTA may issue a regulatory alert to inform other establishments in the human application sector, and / or competent authorities in other EU member states where there may be implications for establishments outside the UK.
The HTA retains a register of the notifications it receives from establishments. The HTA has a statutory obligation to report annually to the European Commission on the notifications it has received. Additionally, the HTA is participating in a pilot on surveillance and vigilance as part of the EUSTITE project, more information about this project can be found at www.eustite.org
The HTA is currently developing a communications plan to determine the best ways of sharing wider learning from SAEs or SARs, to the human application sector. Once finalised, details will be available on this website.
Third parties and end users should report suspected SAEs or SARs to the licensed tissue establishment within 24 hours of the discovery of the event or reaction. Tissue establishments should be able to respond to SAEs and SARs within this time frame inside normal operational hours.
If you are licensed by the HTA for procurement, you should report any suspected SAEs or SARs, which may influence the quality and safety of tissues and / or cells, directly to the HTA. You should also notify any tissue establishments who have received the tissue and / or cells as appropriate.
If the suspected SAE or SAR is linked to donor selection, procurement or donor testing then you should notify the HTA.
Yes, if the suspected SAE or SAR occurred in the UK, you should report to the HTA. You should also report to any organisations in other countries to which you have supplied implicated tissues / cells.
A follow-up report should be submitted using the online system within 24 hours following completion of the internal investigation.
For SAEs, the follow-up report should include details of the investigation, including a root cause analysis and details of any corrective or preventative actions identified.
For SARs, the follow-up report should include details of the investigation, including confirmation of whether it was an SAR, the clinical outcome, the outcome of the investigation and any corrective and preventative actions identified.
