Withholding and withdrawing life-support in adults in emergency care: joint position paper from the French Intensive Care Society and French Society of Emergency Medicine

For many patients, notably among elderly nursing home residents, no plans about end-of-life decisions and palliative care are made. Consequently, when these patients experience life-threatening events, decisions to withhold or withdraw life-support raise major challenges for emergency healthcare professionals. Emergency department premises are not designed for providing the psychological and technical components of end-of-life care. The continuous inflow of large numbers of patients leaves little time for detailed assessments, and emergency department staff often lack training in end-of-life issues. For prehospital medical teams (in France, the physician-staffed mobile emergency and intensive care units known as SMURs), implementing treatment withholding and withdrawal decisions that may have been made before the acute event is not the main focus. The challenge lies in circumventing the apparent contradiction between the need to make immediate decisions and the requirement to set up a complex treatment project that may lead to treatment withholding and/or withdrawal. Laws and recommendations are of little assistance for making treatment withholding and withdrawal decisions in the emergency setting. The French Intensive Care Society (Société de Réanimation de Langue Française, SRLF) and French Society of Emergency Medicine (Société Française de Médecine d'Urgence, SFMU) tasked a panel of emergency physicians and intensivists with developing a document to serve both as a position paper on life-support withholding and withdrawal in the emergency setting and as a guide for professionals providing emergency care. The task force based its work on the available legislation and recommendations and on a review of published studies.

[Refractory cardiac arrest patients in prehospital care, potential organ donors]

Under the authority of the French Biomedicine Agency, a new care pathway integrates refractory cardiac arrest patients into a process of organ donation. It is a medical, logistical and ethical challenge for the staff of the mobile emergency services.

Protocols for uncontrolled donation after circulatory death: a systematic review of international guidelines, practices and transplant outcomes

INTRODUCTION

A chronic shortage of organs remains the main factor limiting organ transplantation. Many countries have explored the option of uncontrolled donation after circulatory death (uDCD) in order to expand the donor pool. Little is known regarding the variability of practices and outcomes between existing protocols. This systematic review addresses this knowledge gap informing policy makers, researchers, and clinicians for future protocol implementation.

METHODS

We searched MEDLINE, EMBASE, and Google Scholar electronic databases from 2005 to March 2015 as well as the reference lists of selected studies, abstracts, unpublished reports, personal libraries, professional organization reports, and government agency statements on uDCD. We contacted leading authors and organizations to request their protocols and guidelines. Two reviewers extracted main variables. In studies reporting transplant outcomes, we added type, quantity, quality of organs procured, and complications reported. Internal validity and the quality of the studies reporting outcomes were assessed, as were the methodological rigour and transparency in which a guideline was developed. The review was included in the international prospective register of systematic reviews (Prospero, CRD42014015258).

RESULTS

Six guidelines and 18 outcome studies were analysed. The six guidelines are based on limited evidence and major differences exist between them at each step of the uDCD process. The outcome studies report good results for kidney, liver, and lung transplantation with high discard rates for livers.

CONCLUSIONS

Despite procedural, medical, economic, legal, and ethical challenges, the uDCD strategy is a viable option for increasing the organ donation pool. Variations in practice and heterogeneity of outcomes preclude a meta-analysis and prevented the linking of outcomes to specific uDCD protocols. Further standardization of protocols and outcomes is required, as is further research into the role of extracorporeal resuscitation and other novel therapies for treatment of some refractory cardiac arrest. It is essential to ensure the maintenance of trust in uDCD programs by health professionals and the public.

French survey of the first three-years of liver transplantation activity from uncontrolled donors deceased after cardiac death

OBJECTIVE

To assess the first three years of French activity related to liver transplantation from uncontrolled donation after cardiac death (uDCD).

STUDY DESIGN

Prospective and observational study in the three active centres authorized by the French Biomedicine Agency.

PATIENTS AND METHODS

All patients deceased between 2010 and 2012 after an uncontrolled cardiac arrest admitted to one of three centres (Pitié-Salpêtrière, Saint-Louis or Bicêtre hospitals, AP-HP, Paris, France) and potentially eligible for liver recovery were included. Abdominal normothermic oxygenated recirculation (ANOR) was used for graft preservation.

RESULTS

One hundred twenty-six potential uDCD donors were identified as eligible for liver recovery after hospital admission. The main causes of organ recovery failure were technical failure related to ANOR (29 patients, 23%), refusal of consent (39 patients, 31% of potential uDCD donors and 40% of asked relatives) and abnormal hepatic transaminases up to 200 UI.L(-1) during ANOR (24 patients, 19%). Finally, 11 livers were transplanted. Process efficiency was 9% [95% CI: 4-15%]. One-year recipient survival was 82%, [95% CI: 48-98%] and one-year graft survival was 64% [95% CI: 31-89%].

CONCLUSION

Liver transplantation from uDCD donors is achievable in France, despite low process efficiency.

What does "presumed consent" might presume? Preservation measures and uncontrolled donation after circulatory determination of death

One of the most controversial aspects in uncontrolled (out-of-hospital) donation of organs after circulatory death (uDCD) is the initiation of preservation measures before death. I argue that in so-called opting-out systems only under very stringent conditions we might presume consent to the instauration of those measures. Given its current legal framework, I claim that this is not the case of Spain, a well-known country in which consent is presumed-albeit only formally-and where uDCD is currently practiced.
