Donation after circulatory death (DCD) can be performed on neurologically intact donors who do not fulfill neurologic or brain death criteria before circulatory arrest. This commentary focuses on the most controversial donor-related issues anticipated from mandatory implementation of DCD for imminent or cardiac death in hospitals across the USA. We conducted a nonstructured review of selected publications and websites for data extraction and synthesis. The recommended 5 min of circulatory arrest does not universally fulfill the dead donor rule when applied to otherwise neurologically intact donors. Scientific evidence from extracorporeal perfusion in circulatory arrest suggests that the procurement process itself can be the event causing irreversibility in DCD. Legislative abandonment of the dead donor rule to permit the recovery of transplantable organs is necessary in the absence of an adequate scientific foundation for DCD practice. The designation of organ procurement organizations or affiliates to obtain organ donation consent introduces self-serving bias and conflicts of interest that interfere with true informed consent. It is important that donors and their families are not denied a 'good death', and the impact of DCD on quality of end-of-life care has not been satisfactorily addressed to achieve this.
IntroductionA mandatory implementation of donation after circulatory death (DCD) from eligible patients facing imminent or cardiac death in hospitals across the USA was introduced at a national conference and is to be effective from January 2007 [1]. The DCD requirement is focused on patients who are neurologically intact or do not fulfill neurologic death criteria before withdrawal of ventilator support [2]. The mandatory requirement will be implemented through the collaboration of the Institute of Medicine, Joint Commission on Accreditation of Healthcare Organizations, Center for Medicare and Medicaid Services, and the Department of Health and Human Services (see the glossary of terms in Table 1) [3,4].The transplantation community has been reorganized into 58 donation service areas (DSAs) to cover the entire country [5]. Each DSA is centered on one organ procurement organization (OPO) that facilitates the recovery and flow of transplantable organs from donor hospital(s) to regional transplant center(s) within a defined geographic location. Each of the DSAs will have to meet a target goal of 75% or higher of cadaveric organ donation rate from its affiliated hospitals.
Determination of circulatory death for organ procurementThe uniform determination of death relies on irreversible cessation of circulatory or neurologic function. The unitarian determination of death by either neurologic or circulatory criteria rather than fulfilling both criteria simultaneously is accepted as the standard for cadaveric organ procurement [2]. The DCD criteria relies on expert opinion, which permits the procurement process after 5 min of apnea, unresponsiveness, and pulselessness [6].The pivotal assumption that DCD w...
