[Brain death protocol].

BACKGROUND: Many states require hospitals to complete a form for each patient who dies, reporting the patient's organ and tissue donation eligibility status, whether a request was made, and the outcome of the request. A study was conducted to determine the accuracy of state-required forms in documenting organ eligibility and procurement activities. METHODS: Four Level 1 trauma hospitals in northeast Ohio were sampled by using a weekly review of all deaths. Detailed chart reviews were conducted on a total of 2,270 deaths occurring during a six-month period in 1997, interviews with health care providers and staff members at organ procurement organizations were held, and records of the local Ohio Department of Health (ODH) were reviewed. Agreement between these data sources and the ODH form were compared to evaluate whether the ODH form correctly documented patients' eligibility status, occurrence of a donation request, and donation request outcome. Descriptive statistics and sensitivity and specificity analyses were completed. RESULTS: The quality of the information provided through these forms was variable. Problems included missing, inaccurate, and contradictory data. State reporting forms overrepresented the size of the organ donor pool by about four times, and requests for donation and consent to donation were inaccurately reported. Hospital form completion rates ranged from 12% to 82.6%. CONCLUSIONS: Basing the evaluation of hospital or statewide organ procurement performance on summary information provided by these forms would lead to an inaccurate picture of organ procurement activities in the state.

[Disorders of consciousness: the basis for ethical assessment].

During the past few years there is an ethical debate about neurological disease entities that are characterised by a) prolongation of life owing to medical treatment, b) limited chances of cure, and c) impaired to unbearable life quality: akinetic mutism, vegetative state ("Wachkoma", apallic syndrome), and locked-in syndrome. These are compared to typical coma and brain death. According to Gerstenbrand (1967) [34] the vegetative state is differentiated into the transitional state following typical coma, the variations of typical and incomplete vegetative state, the remission state and the "Durchgangssyndrom" (characterized by preserved wakefulness with affective lability, disorientation, and amnesia). With regard to pathogenesis we differentiate posttraumatic and posthypoxic origin and variable lesions in cerebral cortex, thalamus or mesencephalic reticular formation. Uncertainty of prognosis is stressed. In respect of brain death we compare a) neocortical death, b) brain stem death, and c) whole brain death, and discuss problems of difficult delimitation and uncertainty of diagnosis. These syndromes are compared to anencephaly and hydranencephaly. Regarding the locked-in syndrome, typical, incomplete and complete (total) forms are distinguished. The differential diagnosis between the complete locked-in syndrome and brain stem death seems problematic. Difficulties in decisions limiting therapeutic effort stem from a) essentially intuitive judgement about observations, b) variability of syndromes and courses, c) uncertainty of prognosis, and d) differences in understanding and valuation throughout society. Emphasis is on a trustful and open colloquy among the persons concerned.
