Why Nurses Should Be More Prominent
Nurses are better suited than doctors to health promotion and more likely to be where the problems are.A daunting challenge to improving global health is the need for the right number of adequately trained healthcare workers in the right places.
Currently, the World Health Organization estimates that the world needs 4 million additional healthcare workers, and those we have are poorly distributed. Africa has 25% of the global disease burden, but only 3% of healthcare resources and 1% of health workers. In contrast, North America has 3% of the disease burden, but 25% of healthcare resources and 30% of health workers.
Of the approximately 60 million health workers, roughly 9 million are doctors and 14 million are nurses and midwives. The ratio of nurses to doctors varies widely: about four to one in many developed countries, but some countries have more doctors than nurses—for example, Pakistan and Mexico. In Africa, however, nurses greatly outnumber doctors. In August 2004, Cross River State in Nigeria reported 72 doctors and 1,037 nurses for 3 million people. The state had one part time obstetrician; the WHO recommended that there should be 120.
Until now, healthcare systems have generally been dominated by hospitals and concerns with the “four Ds”—doctors, disease, drugs and death. Discussions on health have been led by what Nigel Crisp, once chief executive of Britain’s National Health Service (the world’s largest employer of health workers), has called “medico-academic-commercial-governmental” interests. These interests have combined to convince the rich world that it needs more doctors, hospitals, and technical treatments. This strategy worked well in the 19th century.
That was then. This is now. In the rich as well as the poor nations of the world, chronic, non-communicable disease is taking over from infectious disease, and health systems are failing to adapt. Health systems in poorer countries cannot afford to copy the systems that exist in rich countries, and it would be wise not to do so. Organizations like the world’s biggest non-governmental agency, BRAC in Bangladesh, for example, emphasizes the importance of community, family, lifestyles, culture, and behavioral and social factors in health, factors that are the foundation of nursing care. And Ethiopia is trying to build a system based on health, not disease.
The advancement of non-communicable diseases in developed and developing countries and the need for professionals who can implement health promotion and intervention strategies lead us to believe that there is a strong case for building health delivery systems led by nurses rather than doctors. There are strong reasons for this. One is the presence of nurses in underserved regions. Most people in low –and middle–income countries live in rural areas; the WHO reports that more than three quarters of doctors are concentrated in cities. Nurses also tend to be concentrated in cities where hospitals are located, but some 40% are based in rural areas.
Well-trained and qualified nurses can give anaesthetics, remove cataracts, and do Caesarean sections. Nurse practitioners who can prescribe provide services akin to general practitioners with an added emphasis on holistic care and promotion of healthy lifestyles. It is common for patients to feel less intimidated and more comfortable communicating with nurses than doctors and thus more willing to disclose their health concerns and needs. Most importantly, nurses are more adept at some patient-centered activities than doctors, particularly following protocols for the treatment of patients with chronic conditions like diabetes, asthma and high blood pressure. Increasingly, healthcare is much more about careful chronic disease management in concert with the patient’s preferences and values, than it is about diagnosis, an area where doctors excel.
The greatest advantages of nurses in leading the way toward global health are subtle. Nurses are more interested in health promotion and disease prevention, whereas 99% of medical education is about diagnosing and treating disease rather than implementing care plans for healthy lifestyles. Nurses tend to be more comfortable working in teams than doctors, who are more individualistic, and some nurses seem to find it easier than doctors to think about systems—leaders in global health require thinking in systems.
Evidence supports the positive impact that nurses, particularly advanced practice nurses, make on quality, affordability and access to care without compromising impacts on patients. In this 2010 International Year of the Nurse, for all the reasons cited, we believe that nurses should take the lead in improving global health.
We are pleased that our intentionally provocative article has prompted such a reaction but disappointed that the debate has produced such superficial and one-dimensional responses.
Unfortunately, we are not surprised by the vitriol in some of the responses. One of the authors (RS), a former editor of the British Medical Journal (BMJ), published a theme issue that focused on the collaboration between nurses and doctors. This publication included several research studies as to nurses’ abilities to do much of what physicians do and sometimes better, particularly following protocols (1-4). Several articles focused on promoting health after patients had been discharged from hospital and in rural and urban clinics and community based settings – similar to the descriptions in our original article.
As with this publication, these articles elicited hostile reactions from doctors who seemed to feel threatened by the advance of nursing as a profession(5). Similarly, the movement in Britain, Canada, the United States and Australia to make nursing a graduate based profession has produced embarrassing scoffs from many doctors (6, 7). There have been other bitter outpourings in the blogosphere before with what has been coined “One of the most ancient battles in the medical profession…that between doctors and nurses” (8).
Perhaps we overpitched our article. We were asked to be provocative, and we were. We are not arguing that doctors do not have a role in global health, rather that nurses are fully capable of playing a more prominent role and that these nursing resources should be more broadly used. In fact, nurses already work in tandem with other health professionals and have taken the lead in global health promotion; other health professions, including physicians, have often resisted this notion (9, 10, 11).
Ultimately, it is about doctors, nurses, other health professionals—and increasingly community health workers who have no professional training—working effectively together for the benefit of patients. This work needs to focus on improving public health, promoting health and reducing chronic, non-communicable diseases related to lifestyle (obesity, cardiovascular disease, diabetes, lung cancer) that are spreading rapidly in developing and developed countries (12, 13).
As the editor of Scientific American Lives has pointed out, we were not asked to supply references or data; however, there is ample evidence to support all that we highlight in our article. Some of the evidence is summarised in the articles published in the BMJ and in our other references (1, 2, 9, 16).
The Cochrane Library, probably the best repository of evidence on what works in health care, contains many systematic reviews on the effectiveness of nurses in a variety of roles (14); here is the conclusion from just one source:“The findings suggest that appropriately trained nurses can produce as high quality care as primary care doctors and achieve as good health outcomes for patients” (15).
The benefit of provocative articles is the debate that ensues as it invites us all to think more critically about complicated issues. We look forward to the ongoing deliberation and the opportunity to witness demonstrated changes in the ways in which health workers can cooperate to improve global health, particularly given the dearth of resources.
There is a growing global shortage of nurses (16). Pervasive negative comments on the part of doctors toward nurses do not create an environment that is conducive to recruiting sorely needed men and women into the nursing profession. This shortage exacerbates the problem of promoting health and providing adequate care to our ever growing and aging populations in rural and urban regions. (6, 7) In turn, we continue to fail the people who need us the most.
