THE DEPENDENT , INDEPENDENT AND INTERDEPENDENT FUNCTIONS OF THE NURSE PRACTITIONER — A LEGAL AND ETHICAL PERSPECTIVE CHARLOTTE SEARLE OPSOMMING

Die funksies van die verpleegkundige kan beskou word as synde afhanklik, interafhanklik en onafhanklik. Die tradisionele beskouing van die betekenis van veral die aflianklike funksie word egter bevraagteken vanuit die wetlike en etiese perspektiewe wat in Suid-Afrika geld. Omdat die verpleegkundige verantwoordelik en aanspreeklik is vir alles wat sy doen of laat is haar funksie slegs af­ hanklik van wat die Wet, wat haar praktyk rig, voorskryf. Die interafhanklike funksie verwys na die interafhanklikheid tussen die verpleegkundige, die pasiënt en ander lede van die gesondheidspan. Die verpleegkundige en die geneesheer is mede-verantwoordelik vir die welsyn van die pasiënt. Die onafhanklike funksie van die verpleegkundige het te doen met verpleegdiagnose, behandeling en sorg en die wyse waarop sy haar pligte uitvoer en daarvoor verantwoordelikheid aanvaar. Hierdie drieledige aard van die verpleegkundige se praktyk blyk reg deur die hele geskiedenis van die beroep.


INTRODUCTION
In general, contemporary nursing literature from W estern countries does not take a bold stand on the very controversial issue of the de pendent and independent functions of the nurse practitioner.The authors write as if they are skating on very thin ice.Text books on nursing imply a great deal about the practice potential of nurses but ever and anon there is a subtle reversion to the concept that nursing has cer tain dependent functions, meaning functions that require a doctor's authorisation, and certain indepen dent functions that are carried out on the nurse's own initiative, and responsibility.In general the m ajor ity of authors consulted appear to This paper was presented at the 1st Inter national Congress on Nursing Law and Ethics which took place in Jerusalem, Israel, June 13-17, 1982, and will appear in Book of Abstracts of the Congress which is at present in print and will be available shortly.
subscribe to the concept postulated by Sarney when he says A good nursing practice act will separate the independent functions (what nurse can do on her own) from the depen dent functions (what she can do only under the direction o f a doctor) (Sarney 1968 : 18).
The author questions this stand point.We are living in an era of multi-disciplinary teamwork in the health field.In this team the patient is the leader of the team , not the doctor, although the doctor has cer tain specific levels of expertise that other members of the team do not have and in consequence makes the major diagnostic and therapeutic decisions.These decisions have largely to be implemented by other members of the health team.In this sense he then assumes direction of the total health care programme.Yet, in South Africa at least there is no law that says he is the leader, for chiropractors, psychologists, osteo paths, nurses and midwives all have legal right of practice.All these professionals may call him in to share the decision-making process, treatm ent and care of their patient.In some cases he may refuse to do so.

THE QUESTION OF THE DE PENDENT, INDEPENDENT AND INTERDEPENDENT FUNCTIONS OF THE NURSE
It is precisely this position that raises the question of the dependent function of the nurse being one that is dependent on the doctor.
I believe that the functions of the nurse should be described as depen dent, interdependent and indepen dent with a shift in the traditional meaning of the dependent function.

Dependent function
The dependent function of the nurse is based on the law which authorises her practice, as well as on common law and relevant statu tory laws.It is not based on that which the doctor prescribes, re quests or directs for the patient.In accepting such direction or pre scription the registered nurse acts as a p r o f e s s io n a l p e r s o n a n d is responsible and accountable for her own acts and omissions.
W ithout the observance of the provisions of the nurse practice act, she becomes criminally liable and without the observance of other health related legislation she may become civilly or criminally liable.The law is the system of rules that provides order in professional prac tice.It is the law, and only the law, that authorises her professional acts.She is dependent on the law for every aspect of her professional role and function.It must be em phasised that the locus of the de pendent function of the nurse is, and remains, the law empowering her to practise.This includes the regulations made by the subsidiary legislative authority, namely the professional registration and con trolling authority -the South Afri can Nursing Council.It further in cludes decisions given by the courts anent the interpretation of such laws.

Interdependent function
The interdependent function relates to the inter-relationship of the nurse with the patient and with other members of the health team.In particular it relates to the inter dependence of nursing and medi cine.The nurse, whether as insti tutional practitioner or as private contractor, is not the servant or subordinate of the doctor.She is a registered nurse practitioner, en tirely responsible and accountable for her own acts and omissions to the registration authority, the South African Nursing Council, and in the broader sense, to the courts.Where she accepts a prescription, request or direction for treatm ent of a patient from a doctor, she does so as an independent practitioner on behalf of her patient and as a shared responsibility with the doctor.She acts in the interests of her patient and in so doing has a joint responsi bility with the doctor for ensuring that the patient is receiving the pre scribed diagnostic and therapeutic care as well as the relevant nursing care.In other words, the patient is her patient as much as he is the patient of the doctor.She cannot distance herself from this elem en tary fact.Doctor and nurse have an interdependent and reciprocal re sponsibility.Neither can provide all the health care the patient needs.It is a joint as well as a broader team effort.In this respect a very sub stantial element of co-ordination of team activities is done by the nurse in the interest of the patient.The interplay of activities betw een doctor and nurse epitomises the in terdependence of their functions.
The interdependent function is clearly recognised in the various health professional registration acts and in the regulations made there under.It is interesting to note that in South Africa, interprofessional co-operation is limited to those pro fessions that are duly registered or enrolled under Act of Parliament, that is those that are dependent on legislation for their practice.Within these param eters all participants in any patient care situation have mutually interdependent, but also independent functions.Throughout such interdependent action the nurse remains responsible and ac countable for the professional acts of commission or omission.

Independent function
The independent function of the nurse has two dimensions.One di mension relates to all those aspects inherent in nursing diagnosis, treat ment and care which are the normal prerogatives of the nurse.The other dimension is concerned with the manner in which she carries out any of her duties as a registered nurse, whether this be an independent or interdependent function.W hatever she does, she does on her own re sponsibility and accountability for in law she is personally liable for her acts of omission or commission.She and she alone remains account able for her actions.Only she can decide whether she is legally able, or knowledgeable and competent enough, to accept a specific pre scription or direction from a doctor, or is able to participate in the care provided by other members of the health care team.Once she has in dicated acceptance she has made an independent decision and accepts full responsibility and accountabi lity for her decision and actions.
Even her decision to observe the provisions of the nurse practice or related laws is an independent func tion for which she is personally re sponsible and accountable.It is im portant to note that neither the nurse, nor the doctor, nor any other member of the health team is an autonomous practitioner, for such a practitioner does not exist.All the members of the multi-disciplinary health team are responsible and ac countable to the patient, the regis tration authority and the law of the land, which is the vigilant sentry before the door of everyone's pro fessional life.All are accountable, and if one is accountable one cannot be autonom ous, be one doctor, nurse, psychologist, social worker, physiotherapist, or any other member of the health team.
The nurse is solely responsible and accountable for her own prac tice whether this be in a fee-for-service situation or in a salaried situ ation where she has to accept responsibility for a num ber of patients.This is the basis of her pro fessional practice in South Africa.Her independent function super sedes and indeed pervades her in terdependent function.(South Afri can Nursing Council Regulations, 1950) From where does she derive this authority, this delineation of func tion?These three functions are squarely based on the law govern ing the practice of medicine and of nursing in South Africa and on legal decisions which have been given by the courts in law suits involving p a t i e n t s , d o c to r s a n d n u r s e s (Nathan 1957 p.61-101).W ithout such laws and legal decisions pro fessional practice for all health pro fessions would be chaotic.These laws are not a restriction upon the freedom of a professional, but a gateway to greater freedom foi they establish certain rules that, the health practitioner may not trans gress.These laws are made to free the professional, not to bind him, by telling him what he may do with out transgressing on the equal li berty of other health professionals.In a free enterprise health care system such as pertains in South Africa, the law and its regulations impose certain limits of action upon both doctor and nurse.Both may charge fees for patient care, but neither practitioner is free to charge the patient the maximum fees that he/she may wish to impose.The maximum fees chargeable in private practice are prescribed by the medi cal and nursing councils respec tively.Neither may such practition ers enter into an agreement whereby the patient undertakes to assume re sponsibility fo r negligent treatment.(Strauss & Strydom, 1967: 317.)All registered health professionals, in cluding the doctor and the nurse, are not only dependent on the laws and regulations authorising their practice but within the ambit of their professional code of ethics cannot perform professional acts for which they are not adequately trained and/or insufficiently experi enced except in an emergency.(Strauss, 1981: 4.) Common law is explicit in this regard, namely that a practitioner who performs such acts may be held liable fo r damage or injury suffered by the patient in con sequence thereof on the basis o f neg ligence.(Strauss, 1981: 4.) This is a very powerful inducive to responsi ble action in which the practitioner has the independent function of personal responsibility and account ability.

EXCLUSIVE RIGHT OF THE DOCTOR TO CLINICAL RE SPONSIBILITY NOT ESTABLISHED IN LAW
Nothing in an agreement be tween doctor and patient requires the doctor to provide all the care the patient needs, for clearly in the m ulti-disciplinary team c o n te x t, and in the very nature of modern total care, this is unthinkable.The doctor cannot and does not have sole clinical responsibility for the patient.
In a country with a well regulated health practice system some author ity has to authorise practice and assign responsibilities.This is done by Parliament which enacts legis lation for the regulation of the var ious professions in the interests of the public, (Strauss & Strydom, 1967: 9) and on this legislation the professional is dependent.

NURSES MUST TAKE A STAND ON THE MEANING OF THE DEPENDENT, INDEPEN DENT AND INTERDEPEN DENT FUNCTIONS
For most of nursing's long history there is evidence that nursing has always had this three dimensional basis of practice.An attem pt is made to sketch this assertion.

Preliterate society
In preliterate societies the locus of authority for any action relating to a member of the family rested with the head of the family and through him to the extended family, the clan or the tribe.The dependent func tion stemmed from this, namely the law of the head of the family.The independent function related to the care provided by the responsible family member who had to exercise great responsibility and account ability in carrying out such care.The interdependent function was very much to the fore, for within the particular social pattern the pro vider of care had very definite inter d ep e n d en t resp o n sib ilitie s with other members of the extended family or clan and with the tradi tional healer.

Early Hebrew society
T h e s e s e lfs a m e f u n c tio n s a re epitomised in the early Hebrew period by the legal and ethical stance adopted by the midwives Siphra and Pua who disregarded the injunction of the Pharaoh that they had to kill all the newborn male in fants born to the people of Israel.Awareness of the temporal laws of Egypt, but utter obedience to the laws of Jehovah, close interdepen dence with the leaders and teachers of their people and independent action by the midwives charac terised the actions of these mid wives.(Exodus 1: 15-21)

The Hippocratic period
We see a new development in the Hippocratic period where there ap pears to be a shift away from this approach.Shryock quotes a trans lation which indicates the need for and the position of the nurse with reference to instruments used in an operation.But if another gives them he must be ready a little before hand and do as you direct (Shryock, 1959: 53).Clearly a dependent position on the physician.It has not been possible to trace what the measure of responsibility and accountability was in such cases.It appears that the physician assumed an all power ful role.These deductions may be wrong.

DECEM BER 1982 CURATIONIS
The early Christian period The monastic, crusader, military and secular nursing orders were all dependent for the provision of health care on Canon Law, or the laws of the church and the rules of the respective Orders approved by the church.These Orders all acted on the Christian ethic as exempli fied in Christ's teaching that identi fied the love of one's neighbours with the love of God in his promise that inasmuch as ye have done unto the least o f these m y brethren, ye have done it unto me (Matthew 25:40).With the words I was sick and ye visited me, nursing was lifted to a plane of moral obligation, and an ethical tradition was born.The locus of authority was Canon Law, on which the dependent function of the nurse was based.A very strict in te rd e p e n d e n t fu n ctio n ex isted with other members of the religious order who shared patient care, and with the priests for spiritual care, but within these param eters the provider of nursing care had the in dependent function of diagnosing, prescribing and providing treatm ent and care, and of ensuring that her interdependent functions were car ried out within the dictates of the policy of m other church.For all this she was held responsible and ac countable to the superiors of the order and to the m other church.
The above pattern also flourished in feudal times when the lady of the manor provided care within iden tical param eters.
Throughout the long history of the Christian church, the men and women who carried the Christian faith and W esternised healing ser vices to all corners of the earth pro vided nursing within these para meters.Common law apparently made little impact on their practice.Canon law was the foundation on which they built -it was their sole source of authority.It was the 19th and 20th Century developments that highlighted the common law components of practice and brought statutory foundations for the prac tice of nursing and medicine.
In all these periods of nursing his tory, except perhaps in the Hippo cratic period, accountability was a 22 well entrenched concept.Sanctions of some kind or o ther always existed and could be imposed on those who failed in their account ability.

The Dark Ages in health care
The eminently logical and orderly system of health care provided under Canon Law fell into disuse at the time of the Reform ation, when the care of patients was wrested from the hands of the great religious orders.Felons, indigents, drunken slatterns, even other patients pro vided such care as existed in the Poor Law institutions.Chaos in the institutionalised care of the sick threw the functions of the provider of nursing care into disarray, with no clear distinction between the functions of a nurse and the func tions of the lowest grade of do mestic servant.

The Nightingale era
When Florence Nightingale came on the scene in her struggle to reor ganise hospitals and health care sys tems, and working as she did within a military system, she totally sacri ficed the potential legal functions of the nurse to the orders o f the doctor, that is to the military orders of a military officer.She required total dependence and absolute o b e dience to the doctor within a military hierarchial system.M oreover she required the submissiveness akin to that of the religious sister as well as the unquestionable obedience of a person in the military system who was subordinate to the officer class.To enforce respectability in nursing she had to require rigid observance to military discipline and orders.In the process she underm ined the professional development of nurs ing even after legislation was en acted for registration of nurses and the nurse was given a legal role of her own.She started the concept of the nurse having a function depen dent on the doctor.W ith the wisdom of hindsight, we lay this ac cusation at her door, forgetting that we who have lived in an era of pro fessional registration of nurses, have happily perpetuated this myth.Our sin is the greater!

CURATIONIS
The pernicious concept of the function of the nurse being depen dent on the orders of the doctor was carried to every part of the world where the Nightingale system pene trated.By five words -the orders o f the doctor -uttered in a male d o m in a te d , V ic to ria n , m ilitary milieu, nursing practice was denied its legitimate professional rights and responsibilities for many decades.In some parts of the world this con cept still persists.

HOSPITALS
In the struggle to reorganise hospi tals and to keep the costs of this as low as possible, the nurse was made the tool for such reorganisation.H er own professional rights and resp o n sib ilitie s w ere ru th le ssly denied her, even after legislation was enacted enabling her to be a professional practitioner in her own right with only one source for the dependent dimension of her prac tice -the law.
The training system ensured that a docile, brainwashed, manageable person, ill-equipped to fight for her professional rights, provided the cheap, yet disciplined and well skilled service that enabled hospi tals to exist, medical schools to flourish, and medical practitioners to grow prosperous on the sweated labour of the nurse.The myth that the nurse was dependent on the medical practitioner for the authori sation of her practice, and that she was subservient to him, persists de spite legislation to the contrary.This approach resulted in the nurse seek ing power and authority in the ad ministrative system of the health service.She relegated the all impor tant clinical function which is basic to the authorisation for practice, to a secondary place.Evidence of this abounds around the world.Until the nurse recognises the error in this approach she will not under stand the three dimensional nature of her function and will not appreci ate the vital importance of her de pendent function that has its locus in the law.

FIRST PROFESSIONAL REGISTRATION OF NURSES LOCATED THE DEPENDENT FUNCTION OF THE NURSE IN THE LAW
The very first legislation in the world to recognise nursing as a pro fession and to register nurses, was enacted by the Parliament of the Cape Colony (now the Cape Pro vince of South Africa) on 21 August, 1891.This Act, the Medical and Pharmacy A ct No 34 o f 1891, pro vided for the registration of nurses and midwives on the same register as medical practitioners, dentists, pharmacists and druggists.It pro vided such basic principles for the registration of a professional person as training, examination, certifi cation, registration, disciplinary control, recognition of further study and qualification, protection of the rights of persons registered, as well as the protection of the public to be served.This law and its relevant re gulations provided for the cancel lation of certificates and the with drawal of the right of practice for incompetence, negligence, acts of omission and commission, and con duct unbecoming to a professional person.All this required an inde pendent function and account ability.
Despite the fact that the law clearly delineated the nurse as a se parate category of practitioner, re sponsible for her own conduct and practice, the myth persisted.The author believes that the myth per sisted for an ethical reason that had a very heavy overlay of etiquette.The nurse makes a commitment to patient care that goes beyond her own feelings.She subscribes to both the negative apodosis of primum nocere -doing no harm to the patient, and the positive protasisensuring benefit for the patient.These have their origins in the Hip pocratic concept of being helpful and doing no harm.In the quasi-religious-quasi-military atm osphere of the re-organised hospital service the nurse was enjoined to observe the strict etiquette of acknowledg ing the seniority of the medical offi cer.In time she saw this as an ethi cal obligation, denying her legal de pendent function and her own inde pendent function in the process.Nevertheless in the de facto situa tion she adroitly exercised her inde pendent function without raising any dust about it.It took several lawsuits in South Africa, as well as the establishment of the South Afri can Nursing Council, through the enactment of the Nursing A ct No 45 o f 1944, to bring it home to the nurse that only the said Council, empowered by the law, can deter mine what her practice is, and that she is personally responsible and ac countable for how she exercises her dependent, independent and inter dependent functions.This is slowly being recognised by the doctor and the nurse, but such change is drawn out for it is part of the overall so cietal change in South Africa.As onontbeerlike lid van die gesondheidspan bevorder sy bio-psigo-sosiale welsyn van moeder en baba, die hart van die volk.
