Organ donation from intensive care units in England.

OBJECTIVE--To audit all deaths in intensive care units (excepting coronary care only and neonatal intensive care units) in England to assess potential for organ procurement. DESIGN--An audit in which 14 regional health authorities and London special health authorities each designated a regional liaison officer to identify intensive care units and liaise with Department of Health and the Medical Research Council''s biostatistics unit in distribution, return, and checking of audit forms. Audit took place from 1 January to 31 March 1989 and will continue to 31 December 1990. SETTING--278 Intensive care units in England. PARTICIPANTS--Colleagues in intensive care units (doctors, nurses, coordinators, and others), who completed serially numbered audit forms for all patients who died in intensive care. RESULTS--The estimated number of deaths in intensive care units was 3085, and validated audit forms were received for 2853 deaths (92%). Brain stem death was a possible diagnosis in only 407 (14%) patients (about 1700 cases a year) and was confirmed in 282 (10%) patients (an estimated 1200 cases a year). Half the patients (95% confidence interval 45% to 57%) in whom brain stem death was confirmed became actual donors of solid organs. Tests for brain stem death were not performed in 106 (26%) of 407 patients with brain stem death as a possible diagnosis, and general medical contraindication to organ donation was recorded for 48 (17%) of 282 patients who fulfilled brain stem death criteria before cessation of heart beat. The criteria were fulfilled before cessation of heart beat and in the absence of any general medical contraindication to organ donation in 234 patients, 8% of those dying in intensive care (an estimated 1000 cases a year). Consent for organ donation was given in 152 (70%) of 218 cases (64% to 76%) when the possibility of organ donation was suggested to relatives. In only 14 out of 232 families (6%; 3% to 9%) was there no discussion of organ donation with relatives. Corneal suitability was recorded as "not known" in a high proportion (1271; 45%) of all deaths and intensive care units reported only 123 corneal donors (4% of all audited deaths). CONCLUSION--When brain stem death is a possible diagnosis tests should always be carried out for confirmation. Early referral to the transplant team or coordinator should occur in all cases of brain stem death to check contraindications to organ donation. There should be increased use of asystolic kidney donation, and patients should be routinely assessed for suitability for corneal donation. Finally, more publicity and education are necessary to promote consent.     

Public awareness of organ donation.

A telephone survey of public attitudes toward organ donation and transplantation was conducted in a community in southwestern Ontario. The subjects were selected at random; the response rate was 57%. Of the 50 respondents 62% stated that they had signed the organ donor card accompanying their driver''s licence. These respondents were more likely than those who did not sign it to have discussed organ donation with their families. At least 80% of the respondents said they would agree to donate their organs and those of their next-of-kin, and 80% said that the organ donor card should be considered a legal document. Organ transplantation was regarded by all but one respondent as an acceptable medical procedure. Also discussed were concerns about organ donation and possible strategies to improve the availability of organs for transplantation.     

Brain stem death and organ donation.

Organs for donation are in short supply in the United Kingdom, resulting in allegations that relatives of potential donors are not being asked for consent. Legislation on "required request" has been proposed to overcome this. The incidence, causes, complications, and patterns of organ donation in brain stem dead patients in one referral centre were studied over 12 months. Data were collected on all patients fulfilling criteria for brain stem death or considered suitable for donating organs after circulatory arrest. Forty two patients fulfilled the criteria for brain stem death, and in 10 further patients circulatory arrest occurred before formal testing was finished. The major causes of brain stem death were head injury (28) and intracranial haemorrhage (17). Consent to organ donation was obtained for 24 potential donors, and organs were donated by 23 of them. Twenty nine patients did not donate organs. The commonest reasons for failure to donate were medical unsuitability (13) and the coroner not releasing the body (eight). Consent was not sought in three cases, and the relatives refused consent in the remaining five. This study suggests that required request will not considerably increase the supply of donor organs.
