INTRODUCTION AND BACKGROUND

The CRASH 2 Trial involves patients who have suffered serious injuries and are at risk of life threatening haemorrhage. In this situation, most patients will have some impairment in their level of consciousness caused either by blood loss or coexisting head-injury. In this emergency situation, patients may not be able to provide written informed consent. In addition, the trial treatment has to be administered as soon as possible after injury.

From 1 May 2004 it is necessary that trials be compliant with Directive 2001/20/EC in the UK. To implement this directive, the UK regulation titled "The Medicines for Human Use (Clinical Trials) Regulations (2004)" was published which requires that certain conditions and principles are applied to enable an incapacitated adult to be part of a clinical trial. See CONDITIONS below. For the full regulation please visit the following website:

The EU Directive (2001/20/EC) requires that, prior to participation in a trial, written consent from a legal representative of any person unable to consent for him or herself be obtained.

In the first instance, the legal representative of a person unable to give consent should be close to that person, aware of his/her wishes and independent of the research. This person would be termed the Personal Legal Representative (PeLR).

If this is not possible and there is no one sufficiently close to the potential subject who is willing or able to take on the role, or if a person close enough to the potential subject cannot be contacted before it is medically necessary to give the intervention then someone nominated by the NHS Trust as a Professional Legal Representative (PrLR) will fulfil this role.

The CRASH 2 Trial is conducted in an emergency situation and the protocol requires that treatment is administered as soon as possible after injury. In the majority of cases, patients are unaccompanied. In addition, it can take time for the police to identify and contact someone who can potentially be a PeLR.

In most cases, it is expected that consent for participation will have to be obtained from a PrLR for patients to be enrolled.

OBTAINING LEGAL REPRESENTATIVE CONSENT FOR THE CRASH 2 TRIAL

  • It is the responsibility of each NHS Trust collaborating in the CRASH Trial to nominate suitable personnel to act as PrLR.
  • It is the responsibility of each NHS Trust collaborating in the CRASH Trial to provide general training about the role of a PrLR.
  • It is the responsibility of each NHS Trust collaborating in the CRASH Trial to provide Indemnity for PrLRs.
  • It is the responsibility of each Principal Investigator and the Trial Co-ordinating Centre to provide written trial specific information about the trial to PrLRs to allow them to make an informed decision.
