The biblical figure of Phoebe, described in the first century, is widely recognized by historians as the first visiting nurse, establishing a lineage of care that predates modern medicine by two millennia. In the fifth century BC, the Hippocratic Collection documented skilled observation of patients by male attendants, while around 600 BC in India, the Sushruta Samhita detailed the role of the nurse in dissecting dead bodies to understand anatomy. These ancient practices laid the groundwork for a profession that would eventually evolve from religious duty to a complex science. During the Middle Ages, members of religious orders such as nuns and monks provided nursing-like care across Christian, Islamic, and Buddhist traditions, embedding the ethos of compassion into the fabric of healthcare. The Reformation, however, extinguished the nursing profession in Europe for approximately 200 years when Protestant reformers shut down monasteries and convents, leaving care to the inexperienced and removing traditional caretakers rooted in the Roman Catholic Church. This historical rupture set the stage for a dramatic rebirth of the profession in the 19th century, driven by the horrors of war and the vision of a single woman who would change the world.
The Crimean Rebirth
Florence Nightingale, often considered the first nurse theorist, linked health to five environmental factors: pure air, pure water, efficient drainage, cleanliness, and light, specifically direct sunlight. Her comprehensive statistical study of sanitation in India revealed that after 10 years of sanitary reform, mortality among soldiers in India had declined from 69 to 18 per 1,000. During the Crimean War, Grand Duchess Elena Pavlovna called for women to join the Order of Exaltation of the Cross, and the first section of twenty-eight sisters, headed by Aleksandra Petrovna Stakhovich, reached Crimea in early November 1854. Nightingale's work during this conflict, where no uniform had been created for her employment, laid the foundations of professional nursing and led to one of the first schools of nursing connected to a hospital and medical school. Her influence spread widely in Europe and North America after 1870, transforming nursing from an oral tradition into a discipline grounded in data and environmental science. While Nightingale is the most famous figure, her work built upon the successes of Jamaican doctresses such as Mary Seacole, who practiced hygiene and the use of herbs to heal wounded soldiers in the Crimea, Central America, and Jamaica. Seacole's predecessors, including her mother Mrs. Grant and Sarah Adams, had great success as healers in the Colony of Jamaica in the 18th century, proving that effective care existed outside the male-dominated medical establishment.
Formal use of nurses in the military began in the latter half of the 19th century, with nurses seeing active duty in the First Boer War, the Egyptian Campaign of 1882, and the Sudan Campaign of 1883. The modern deaconess movement began in Germany in 1836, and within a half century, over 5,000 deaconesses had surfaced in Europe. Red Cross chapters, which began appearing after the establishment of the International Committee of the Red Cross in 1863, offered employment and professionalization opportunities for nurses despite Nightingale's initial objections. Catholic orders such as the Little Sisters of the Poor, Sisters of Mercy, and Sisters of Charity built hospitals and provided nursing services during this period. Linda Richards, officially the first professionally trained nurse in the United States, graduated in 1873 from the New England Hospital for Women and Children in Boston and went on to establish nursing schools in the United States and Japan. Agnes Hunt from Shropshire became the first orthopedic nurse and was pivotal in the emergence of the orthopedic hospital, the Robert Jones & Agnes Hunt Hospital in Oswestry. Valérie de Gasparin opened the world's first nursing school in Lausanne, Switzerland, with her husband Agénor de Gasparin, while Agnes Jones established a nurse training regime at Brownlow Hill infirmary in Liverpool in 1865. These pioneers created a global network of care that would eventually span from the Americas to Asia, transforming nursing into a distinct academic discipline.
War and Transformation
In the 19th and early 20th century, nursing was considered a woman's profession, just as doctoring was a profession for men, but the profession transformed again during the Second World War. British nurses of the Army Nursing Service were part of every overseas campaign, and more nurses volunteered for service in the US Army and Navy than any other occupation. The Nazis had their own Brown Nurses, numbering 40,000, and two dozen German Red Cross nurses were awarded the Iron Cross for heroism under fire. Hospital-based training became standard in the US in the early 1900s, with an emphasis on practical experience, yet the Nightingale-style school began to disappear as hospitals and physicians saw women in nursing as a source of free or inexpensive labor. Exploitation of nurses was not uncommon by employers, physicians, and education providers, creating a legacy of struggle for professional recognition. The development of undergraduate and post-graduate nursing degrees came after the war, and nursing research and a desire for association and organization led to the formation of professional organizations and academic journals. Nursing became recognized as a distinct academic discipline, initially tasked to define the theoretical basis for practice, marking a shift from the oral traditions of the past to a rigorous scientific field.
The Modern Shortage
A global survey by McKinsey & Company in 2022 found that between 28% and 38% of nurse respondents in the United States, the United Kingdom, Singapore, Japan, and France said they were likely to leave their role in direct patient care in the next year. The top five factors which they said would make them stay were a safe working environment, work-life balance, caring and trusting team-mates, meaningful work, and a flexible work schedule, with pay ranking eighth on the list. A 2023 American survey found that around 30% were considering leaving patient care, highlighting a crisis that threatens the future of healthcare. Nurses are perceived to be in short supply around the world, particularly in South East Asia and Africa, where the fast-paced and unpredictable nature of health care places them at risk for injuries and illnesses. The international nursing shortage is in part due to their work environment, with nurses consistently identifying stress as a major work-related concern and having among the highest levels of occupational stress among all professions. This stress is caused by the environment, psychosocial stressors, and the demands of nursing, including mastering new technology, emotional labor, physical labor, shift work, and high workload.
The Science of Care
Florence Nightingale's seminal epidemiological study examining mortality among British soldiers during the Crimean War was published in 1858, but nursing practice remained an oral tradition until the mid-20th century. The inaugural issue of Nursing Research, the first scientific journal specialized in nursing, came out in 1952, and during the 1960s, interest in attaining PhDs increased among nurses in the US. Nursing research is increasingly presented as a valid discipline, although lacking a prevailing definition, and the question is further complicated by the numerous interpretations of nursing's defining essence. During the 1980s there was an increased focus on research utilization, and US nursing schools began teaching research methods to facilitate interpretation and integration of scientific findings in routine practice. The evidence-based practice movement, which originated in the field of medicine with Archie Cochrane publishing Effectiveness and Efficiency in 1972, led up to the founding of the Cochrane Collaboration in 1993. Common barriers to the study and integration of research findings into clinical decision making include a lack of opportunity, inexperience, and the rapid pace of evidence accumulation, yet the profession continues to evolve through the integration of research findings with clinical expertise and patient preferences.
The Hidden Dangers
Healthcare has consistently ranked among the industries with the highest rates of musculoskeletal injuries, largely related to patient handling, with anywhere from 30 to 70% of reported musculoskeletal injuries related to patient handling. The most frequently injured body part is the back, with up to 72% of nurses reporting non-specific low back pain, and the US Bureau of Labor Statistics reported that for 2021-2022 the rate of overexertion injuries leading to days away from work for nurses was 45.4 per 10,000 full time employees. Nurses are at risk for workplace violence and abuse, with 57% of nurses in the US in 2011 reporting that they had been threatened at work and 17% being physically assaulted. The three types of workplace violence that nurses can experience are physical violence, psychological violence, and sexual violence, with 80% of serious violent incidents in health care centers committed by patients. Nurses have high rates of occupational burnout at 40% and emotional exhaustion at 43.2%, which increase the risk for illness, medical error, and suboptimal care provision. Interventions can mitigate these occupational hazards, including stress management programs and organizational interventions, and in some Japanese hospitals, powered exoskeletons are used to reduce physical loads.
The Future of Nursing
Nursing is the most diverse of all health care professions, with nurses practicing in a wide range of settings including hospitals, private homes, schools, and pharmaceutical companies. Nurses work in occupational health settings, free-standing clinics, physician offices, nurse-led clinics, long-term care facilities and camps, and even on cruise ships and military bases. Nurses act as advisers and consultants to the health care and insurance industries, and many work in health advocacy and patient advocacy, helping in clinical and administrative domains. Some are attorneys and others work with attorneys as legal nurse consultants, reviewing patient records to assure that adequate care was provided and testifying in court. Digital health platforms connect nurses and nurse assistants with job openings in healthcare facilities, and platforms such as United States-based ConnectRN, Nomad Health, Gale Healthcare solutions or Lantum add resources, career development tools, and networking opportunities. In 2017, the UK's National Health Service began trialing such a platform, and the profession continues to expand its scope through specialties ranging from informatics to palliative care, ensuring that the art and science of caring remains at the forefront of global health.
