Development of clinical ethics committees

What is clinical ethics support?

Clinical ethics support can be described as the provision of support and advice to health professionals and patients on ethical issues arising from clinical practice or patient care. The support can take different forms, but in the United Kingdom the most common model is a committee or group sitting within an NHS trust, usually an acute trust. These committees are multidisciplinary and include lay members. Issues are referred to the committee by clinicians and managers, and some committees are now being approached by local general practitioners. Few committees include patients or their families directly in committee discussions.

The number of trusts with clinical ethics committees is increasing. In 2001 the Nuffield Trust published a survey of all NHS trusts that identified 20 clinical ethics committees.2 A questionnaire survey conducted by the UK Clinical Ethics Network early in 2003 showed that 60 of the 315 acute NHS trusts had a clinical ethics committee (fig).3 We are unaware of any committees in primary care trusts, although two regional committees cover acute and primary care.

Functions of clinical ethics committees

The work of clinical ethics committees falls into three broad areas: providing ethics input into trust policy and guidelines around patient care, facilitating ethics education of health professionals within the trust, and giving advice to clinicians on individual cases (box 2).2 The degree to which the committees engage in each of the functions varies, but there are examples of innovative work in all three areas. For example, some committees are involving patients in developing policies on cardiopulmonary resuscitation, using role play to help clinicians explore ethical dilemmas arising in their work, and developing a system of on-call support for case consultation. As committees become established and recognised, the scope of their work increases and they get more requests for advice from trust staff.

Comparison with other countries

The development of clinical ethics committee in the United Kingdom was largely clinician led. The committees arose because clinicians were identifying difficult issues on which they felt that they needed ethics support and advice.2 4 5 Some countries have had a more top down approach, with committees (often called institutional or hospital ethics committees) forming in response to government recommendation or requirements of regulatory authorities.6 Many hospitals in North America also have ethics consultants, who provide individual support to clinicians, patients, and their families.7 8 Clinical ethics support is less widespread in continental Europe. However, all major hospitals in Norway are now required to have an ethics committee,9 and institutional ethics committees have been a feature of hospitals and nursing homes in the Netherlands for many years.10

Does ethics support make a difference?

It is difficult to evaluate ethics support using a traditional outcomes based model,11 although some US studies have used this approach. A recent study of ethics input in an intensive care unit showed positive outcomes in terms of a reduction in time spent on ventilators among patients who eventually died and in satisfaction of patients' families with the process of care.12

Although measuring specific outcomes of ethics support can be helpful, it ignores other dimensions of ethics support. An equally important aspect is the provision of an explicit and transparent process for engaging with the ethical dimension of clinical decision making. A model of ethics support that facilitates and informs a shared understanding of difficult ethical issues can support and reassure both clinicians and patients, without presupposing that there is an ethically correct outcome. Thus, a principal value of ethics support may lie in its contribution to the process of ethical decision making.

UK Clinical Ethics Network

The UK Clinical Ethics Network is now an important source of information and support for clinical ethics committees and for NHS trusts that are considering providing ethics support for their staff. The network provides a regular newsletter, an annual conference, and educational workshops, and facilitates sharing of information and experience between committees.

The network has also recently launched a website. The site provides contact details for all clinical ethics committees known to the network, ethical and legal discussion, hypothetical cases, and links to national guidelines on ethical issues (www.ethics-network.org.uk). The aim is to provide relevant information that is easily accessible for members, clinicians, and patients. Since its launch, the website has had an average of 105 hits a week, of which 62% are returning visitors. The most common search terms are consent and refusal of treatment.

Future development

Clinical ethics support is now an established feature of many NHS trusts. It has the potential to become a valuable component of high quality health care, but for this to happen it will require support from trust boards, clinicians, and the medical ethics community. The increasing number of clinical ethics committees, and the increasing workload of established committees, suggests that health professionals in the United Kingdom are becoming more aware of the need to openly engage with the difficult ethical issues arising in their work and that ethics committees are seen as a valuable part of this process.
