    E-mail address: (U. Korner).The law regards withholding and withdrawing treatment as the same. It alsodefines the provision of food and drink by mouth as basic care and feeding byartificial means as a medical treatment. It requires doctors to act in the bestinterests of the patient.

    Summary European ethical and legal positions with regard to EN vary slightly fromcountry to country but are based on a common tradition derived from Graeco Romanideas, religious thought and events of the 20th century. The Hippocratic tradition isbased on beneficience (do good) and non-maleficience (do no harm). Religiousthinking is based upon the presumption of providing food and drink by whatevermeans unless burden outweighs benefit. The concept of autonomy (the patientsright to decide) arose following in the decades after the Second World War and isenshrined in Human Rights law. The competent patient has the right to participate indecision making and to refuse treatment although the doctor is not obliged to givetreatment which he or she considers futile or against the patients interests. Theincompetent patient is protected by law. The fourth principle is that of justice i.e.bCentre lemanique dethcGeriatrischer SchwerpundDepartment of Surgery,eDepartment of Surgery,fService dhepatogastroegAbt.

    Ethical and Legal Aspects of Enteral Nutrition 197Introduction

    These guidelines address some of the ethical andlegal issues which are increasingly part of theclinical decision-making process involved in provid-ing nutrition support. The European ethical tradi-tion is based on the GraecoRoman ideas, refinedby religious considerations and further developedduring the 20th century.

    Q: What is the basis for the European ethicaltradition in Medicine?

    A: The Hippocratic ethical code is based onbeneficience i.e. do good, and non-maleficiencei.e. do no harm. This tradition was, however,paternalistic, and it was not until the 20th centurythat the notions of autonomy i.e. the patientsright to decide, and justice i.e. equal rights forall, were introduced. Religious ideas have alsocontributed.Comment: The Hippocratic tradition, refined by

    Roman physicians, was based on the do good butdo no harm principles. It also embodied the notionof confidentiality but eschewed autonomy, and wasmotivated by philanthropia i.e. do good in orderto preserve the physicians reputation. Hippocrateswrote Give necessary orders with cheerfulness andsincerity, turning his (the patients) attention awayfrom what is being done to himy revealing nothingof the patients future or present condition In the1st century AD, Scribonius Largus, physician to theEmperor Claudius, took a step nearer our modernattitude by encouraging physicians to base deci-sions on Humanitas, that is love of mankind, and onMisercordia, or mercy. Enteral feeding has a 500 yrhistory in Europe and its principles were defined byJohn Hunter in 1793, when he wrote concerning apatient with paralysis of the swallowing muscles. Itbecomes our duty to adopt some artificial mode ofconveying food into the stomach, by which thepatient may be kept alive while the diseasecontinues. The concept of starve a fever andfeed a cold, prevalent since Galen in the 4thcentury AD, was abandoned in the 19th century,when several authors emphasised the importanceof feeding in medical care.As a new principle the respect for patients

    autonomy arose in the seventies of the 20thcentury. The competent patient now has the rightto participate in all the decision-making concerninghis treatment, and the law provides safeguards forthe patient who is incompetent i.e. incapable ofunderstanding or making decision. The paternalis-tic approach of Hippocrates was therefore super-seded by that of autonomy. On the other hand,despite a number of recent legal cases, the doctoris still not obliged to submit to pressure by thepatient, relatives or others, to give treatmentwhich he or she believes to be futile or against thepatients interests i.e. the burden or adverseeffects outweigh benefit. European religious tradi-tions, both Christian and Jewish, are sometimeserroneously supposed to favour preservation of lifeat all costs. In fact, Roman Catholic teaching isclear that there should be a presumption in favourof providing nutrition and hydration provided thatit is of sufficient benefit to outweigh the burdensto the patient. This involves judgements concern-ing the quality of life which has assumed increasingimportance in assessing the efficacy of treatment.One may contrast the use of tube feeding insituations where it may not prolong life, but whereit improves its quality, with treatments which mayprolong life at the expense of prolonged suffering.In most countries the physician may not end life,but on the other hand is not required officiously toprolong the process of dying. Orthodox Jewishthinkers regard the dying person in a special lightand argue against impediments to dying in the finalyear of life.The growth of National Health Services in Europe

    has seen the increasing recognition of justice(equal access to healthcare for all) as an importantethical concept. On the other hand the growth indemand for healthcare and new technical develop-ments face all societies with the problem ofsatisfying infinite demand with finite resources.Society and its political representatives have yet

    to face up to the problem of enormously expensiveand sometimes futile treatment of the few, whichmay so consume resources in staff, facilities andmoney as to deny proper treatment of those morelikely to benefit and survive. The doctor is there-fore faced with balancing justice against bene-ficence and autonomy, and trying to deploy thelimited resources available to achieve the max-imum benefit. Through legal and other conflicts(see below), there may be difficulties in the way ofwithdrawing expensive but ineffective treatment inorder to use the resources of the nutrition careteam to better effect. In cases of conflict, theadvice and support of local ethical committees maybe helpful.

    Q: Is there a difference between ethicalprinciples and legal framework?

    A: Yes, although the laws of European countries(which may differ in some details between

  • clemenuco

    provision of adequate fluid and nutrients by mouth


    U. Korner et al.198countries) are based on the common ethicaltradition described above.Comment: Ethical codes of caring professions

    include not only minimal acceptable standards ofbehaviour, but also ideals, and have been describedas the collective conscience of our profession.The law, on the other hand, defends individualrights and liberties and sets minimum standardsbelow which professional conduct can be regardedas lacking in care, negligent or downright criminal.It also protects those who are unable or incompe-tent to make decisions on themselves. In addition,it provides some safeguards and protection fordoctors and other professions. It has embodied theprinciple, for example, that no doctor can beobliged to provide treatment which he/she be-lieves to be against the patients interests or futile.This delicate balance between patients legal rightsand professional judgement has, however, beenthreatened by recent unfortunate legal judgementsin the UK and USA, whose consequences have yet tobe defined. Unprincipled political interference,stimulated by extreme pressure groups, is also athreat that the professions will need to resist.Fortunately, Europe in general has continued tomaintain a liberal and humane approach to theseproblems.In the judgement of risk versus benefit in the

    medico-legal context, it is clearly vital that theprofessional who wishes to avoid or to provide adefence against litigation should be fully conver-sant with the latest medical evidence and beappropriately trained and experienced.

    Q: What are the implications of the law forthe organisation and conduct of nutritionalsupport?

    A: As with other treatments, the best results areobtained by teams trained and organised to carry itout. This is of particular relevance to artificialmeans of nutritional support.Comment: There is sufficient evidence, in the

    case of parenteral nutrition, that specialisednutrition teams obtain the best results, with thefewest complications. There is some evidence also,in the case of enteral tube feeding, that experi-enced and properly organised groups, wor
