Experience of Relatives and Intensive Care Units Caregivers of Controlled Donation After Circulatory Death (CARE-M3)

Description

While withdrawal of life-sustaining therapies (WLST) decision occur significantly more frequently in intensive care units (ICUs), controlled donation after circulatory death (cDCD) evolves end-of-life care and produces a new end-of-life (EOL) model: EOL care now includes the opportunity to donate organs and tissues after death. During cDCD, the patient is still alive while OD process is being discussed and organized. Caregivers can be particularly uncomfortable in this scenario where EOL care and OD in effect overlap. Thus, the implementation of a cDCD program in France, as elsewhere, raised the issue of the potential impact of OD on WLST decision-making processes and EOL practices (particularly sedation). As other countries, the national protocol is nonetheless clear that the decision for WLST must be made in the bests interest of the patient and independent of any consideration of OD, and the donation pathway must not change EOL care. The challenge is not only to identify patients suitable as potential donors but also to provide support to grieving families and to make HCPs comfortable with OD in this particular context. In the specific context of cDCD, developing knowledge on the perceptions and experiences of relatives and ICU caregivers regarding OD is crucial but remains poorly investigated.

Investigators propose to conduct a prospective multicentric observational research to better understand relatives' and ICU caregivers' experience of cDCD.

A relative and/or at least two caregivers (1 physician and 1 or 2 paramedics) are included for any situation of death of a patient in ICU following a decision to withdraw LST and for which OD has been discussed with the relatives, whether or not the organ procurement finally occurred.

Two situations are distinguished:

• WLST without OD possibility: the WLST is initiated while OD is no longer considered for one of the following reasons: medical unsuitability, expressed intend not to be a donor or family refusal, legal issues, logistical problems, hemodynamic instability.
• WLST with OD possibility: the WLST is initiated while OD is still considered, whether or not OD finally occurs for one of the following reasons: circulatory death declared > 180 minutes, excessive warm ischemia time due to normothermic regional perfusion dysfunction or hypoperfusion.

At the time of the discussion about OD with the relatives :

• The screening for inclusion will be done.
• If 1 relative volunteers to participate in the study (non-opposition noted by the investigator), the situation is included in CARE-M3 "relative" section.
• If no relatives volunteer to participate in the study, the situation can be included in CARE M3 for the caregiver section after the patient's death.

After the patient death, wether or not OD occurs:

• 3 caregivers (1 physician and 2 paramedics) can be included. These are the caregivers who are present at the time the WLST is initiated.
• If at least two caregivers volunteer to participate in the study, the situation is included in CARE-M3 caregiver section.

Objectives concerning the relatives

• Primary objective: to study their risk of developing symptoms of post-traumatic stress disorder in the months following the patient's death.
• Secondary objectives: assessment of symptoms of anxiety, depression, complicated grief, assessment of understanding of the decision process to withdraw LST and the cDCD procedure.

Objectives concerning the ICU caregivers

• Primary objective: to study their risk developing anxiety relating to the event.
• Secondary objectives: evaluation of the impact of the cDCD procedure on the WLST decision-making process, end-of-life practices, support at the end-of-life (EOL) and quality of the EOL.
