Brief summary
The purpose of this study is to make a paramedical evaluation of a selection procedure of serious brain-injured patient in therapeutic abstention to a brain death state within 48 hours.
Detailed description
In 2016 in France, 5891 organs have been transplanted. All the transplant's sources are developed (brain death, Maastricht III, living organ donor). However, the French Transplant's plan 2017-2021 require always more transplant, the aim is to reach 7800 transplants in 4 years. To increase the number of transplants, one of the strategies is to actively identify the donors in brain death state and the donors with wider criteria. It's mainly serious brain-injured patients. The procedure of early announcement of organ donation consists in beginning or pursues intensive care on serious brain-injured patient, for whom a decision of abstention of therapeutic active was decided. The only purpose of the medical care is to notice the brain death state that lead to donation. In 2010, an expert group of the "Société de reanimation de langue Française" established guidelines to manage organ's donation in serious brain-injured patient after a stroke. The interest, to admit these serious brain-injured patients in intensive care unit, is to increase the number of donors in state of brain death and so the number of transplants. However the guidelines remain little practised and little known in France. The number of bed in intensive care unit is limited and requires a selection of the potential organ donors. To hospitalised serious brain-injured patients in intensive care unit, there are no validated selection criteria that make difficult the implication of the transplant coordination in this anticipated announcement's approach. In Toulon hospital, a standardize selection procedure was initiated and applied systematically by the transplant coordinator for each serious brain-injured patients. The selected patients will evolve in brain death state in 48 hours and could be organ donors. The aim of this study is to validate a paramedical procedure to increase the number of organ donors.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Study of the evolution to brain death state within 48 hours of seriously brain-injured patients selected by a standardized procedure and hospitalised in intensive care unit. | 48 hours after validation of eligibility | Rate of patients evolving to brain death state during the first 48 hours following the examination which validates patient's eligibility |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of call rate to transplant coordination that don't result in a procedure of anticipated announcement | 48 hours after validation of eligibility | Ratio between the number of non-eligible patients and the total number of calls |
| Evaluation of close family refusal rate for pursuit of care during 48h in intensive care unit | 48 hours after validation of eligibility | Ratio between the number of family refusal and the total number of patients for whom the anticipated announcement procedure was started. |
| Number of refusal causes in the population | 48 hours after validation of eligibility | Number of refusal causes will be presented globally |
| Evaluation of the delay between eligibility validation and the passage in brain death state. | 48 hours after validation of eligibility | The passage delay between eligibility validation and brain death state is defined by the time in hours between the examination which validates patient's eligibility and the diagnosis of brain death state. |
| Evaluation of the rate of patients with organ removal in enrolled patients. | 48 hours after validation of eligibility | Ratio between the number of patient who performed organ donation and the total number of patients included. |
| Number and type of organ harvested by patient. | 48 hours after validation of eligibility | Number of organs collected will be presented globally, by patient and by type of organ transplanted. |
| Number of transplants performed. | 10 days | The number of transplants performed will be presented globally, by patient and by type of organs. |
| Number of patient enrolled by type of service. | 48 hours after validation of eligibility | The number of patient enrolled in the intensive care unit, the Emergency or Neurovascular intensive care unit will be described globally |
| Non harvested organs which have been suggested for transplant | 10 days | The proportion of suggested non harvested organs will be determined as the number of suggested non harvested organs divided by the total number of non harvested organs. Reasons of suggested organs refusal will be presented. |
| Number of patients who performed Maastricht 3 organ donation among patients who didn't evolve to brain death state | 10 days | The rate of patients with Maastricht 3 organ donation will be determined as the number of patients having performed Maastricht 3 organ donation divided by the number of patients who didn't evolve to brain death state after 48hours |
