The editorial is authored by senior author Eileen T. Lake, the Edith Clemmer Steinbright Professor in Gerontology, Professor of Nursing and Sociology, and Associate Director of the Center for Health Outcomes and Policy Research, together with Domenique Villani, a predoctoral fellow at the center, and Ysabella Perez, a recent Penn graduate and research assistant at the center. Their central argument is straightforward but consequential: building genuine climate resilience into the health system requires ensuring that bedside nurses have the organizational capacity and the material resources needed to deliver timely care and continuous surveillance during heat events, when patient volumes can spike suddenly and patient conditions can deteriorate rapidly.

The physiological rationale behind this argument is well established in clinical medicine. Extreme heat places severe stress on the human body, particularly the cardiovascular system, which must work harder to dissipate heat through increased blood flow to the skin. In vulnerable populations, including older adults, people with chronic cardiovascular or respiratory disease, patients taking medications that impair thermoregulation, and those with limited access to cooling, prolonged heat exposure can progress from heat exhaustion to life-threatening heat stroke. Heat stroke is a medical emergency characterized by core body temperatures above roughly 40 degrees Celsius and central nervous system dysfunction, and it can trigger a cascade of complications including rhabdomyolysis, acute kidney injury, coagulopathy, and multi-organ failure. Surviving such a cascade depends heavily on early recognition and rapid, sustained intervention.

This is precisely where nursing care becomes decisive. The editorial emphasizes that the management of heat-related illness requires immediate and resource-intensive nursing surveillance to prevent complications and to catch the signs of rapid patient deterioration before they become irreversible. Continuous monitoring of vital signs, fluid balance, electrolyte status, and neurological function is the daily work of bedside nurses, and during a heat wave the volume of patients needing this level of attention can rise sharply at exactly the moment when a hospital’s workforce is under maximum strain. Nurses themselves are also exposed to the same environmental conditions, and heat events can affect staff wellbeing and performance, adding another layer of pressure on the workforce during surges.

The authors warn that insufficient staffing and inadequate organizational support can severely limit a health system’s ability to deliver standard-of-care treatments during the sudden volume surges that heat waves produce. A hospital may have the physical beds, the cooling capacity, and the IV fluids to handle an influx of heat-affected patients, but if there are not enough nurses to perform the frequent assessments, administer cooling protocols, titrate fluids, and escalate deteriorating patients to higher levels of care, the theoretical surge capacity fails in practice. In this sense, the editorial reframes nurse staffing not as a cost line to be minimized but as a functional limit on how much emergency care a hospital can actually deliver when environmental disasters strike.

The argument rests on a substantial body of research from the Center for Health Outcomes and Policy Research and collaborators, which has repeatedly demonstrated that the ratio of patients to nurses and the quality of the nurse work environment are associated with patient outcomes including mortality, failure to rescue, lengths of stay, and rates of complications. Studies in this tradition have shown that hospitals with better work environments, characterized by adequate staffing, strong nurse-physician relationships, nurse participation in decision-making, and supportive management, achieve better outcomes even at similar staffing levels. Extending this evidence base to climate-driven emergencies is a natural progression, and it suggests that the organizational features that protect patients in ordinary times become even more critical when the system is stressed by a heat crisis.

Looking forward, the editorial does not stop at diagnosis. It outlines actionable recommendations across four domains: research, education, practice, and policy. On the research side, the authors call for studies that specifically examine how staffing and work environment characteristics shape outcomes during heat events, filling a gap in the disaster preparedness literature that has traditionally focused on infectious disease outbreaks, mass casualty trauma, and hurricanes. On education, the implication is that nursing curricula and continuing professional development should prepare clinicians to recognize and manage heat-related illness and to understand the systems-level factors that determine whether such care can be delivered effectively during a surge.

In the domain of practice, the editorial urges health system leaders to incorporate nurse staffing and workplace environment investments directly into disaster preparedness planning, rather than treating workforce questions as separate from emergency management. Concretely, this could mean including staffing models in heat response plans, ensuring that nurses have the equipment and authority to implement cooling and monitoring protocols efficiently, and designing work environments that protect staff as well as patients during extreme temperatures. On the policy front, the authors’ message is directed at regulators, accreditors, and hospital administrators: if extreme heat is now a recurring, predictable public health emergency, then the workforce that delivers the front-line response deserves the same strategic investment and planning attention as any other piece of emergency infrastructure.

The broader context gives this argument urgency. Heat waves in the United States have grown more frequent, more intense, and longer-lasting in recent decades, consistent with the warming trend driven by climate change, and emergency departments in many regions have reported rising numbers of heat-related visits during recent summer seasons. Public health agencies have long emphasized individual-level precautions, such as hydration, air conditioning, and checking on vulnerable neighbors, but the hospital-level response has received comparatively less attention. The editorial’s contribution is to shift the focus from the community to the bedside, insisting that what happens inside the hospital, and specifically how many nurses are available and how well supported they are, is a measurable determinant of who survives a heat emergency.

The authors state their conclusion plainly: extreme heat is no longer just a public health issue, but an immediate hospital preparedness priority that requires treating nurse staffing and supportive work environments as essential emergency infrastructure. As climate projections indicate that dangerous heat events will become more common in the coming decades, hospitals that invest now in their nursing workforce, in both numbers and working conditions, may find themselves measurably better equipped to protect their patients when the next heat wave arrives. The editorial, titled How Nursing Can Strengthen Hospital Preparedness for Extreme Heat, was published in Public Health Nursing in September 2026 and represents a call to action for health system leaders, educators, researchers, and policymakers alike to place the nursing workforce at the center of climate resilience planning.

Wood’s early life unfolded in a Philadelphia that was rapidly becoming the scientific capital of the United States. Born in 1841, he came of age at a time when American medicine was still largely an apprenticeship trade, taught at the bedside rather than in the laboratory. Yet Wood’s generation would transform that landscape, importing the experimental methods of European physiology and pharmacology and building the first university departments devoted to the scientific study of disease. Wood himself would later recount these formative years in his Reminiscences of an American Pioneer in Experimental Medicine, delivered before the College of Physicians of Philadelphia in 1920, near the end of his life. That memoir remains one of the most valuable first-hand accounts of what it took to establish experimental medicine in nineteenth-century America, and it anchors much of the modern scholarship on his career, including the biographical memoir prepared for the National Academy of Sciences by George B. Roth in 1959.

The scale of Wood’s ambitions becomes clearer when one considers the breadth of his appointments. In an era when most physicians confined themselves to a single specialty, Wood held professorships in nervous diseases, in pharmacology and therapeutics, and in general medicine, moving fluidly among fields that today would be considered separate careers. This versatility reflected both his temperament and the state of nineteenth-century science, in which the boundaries between physiology, pharmacology, and clinical medicine were still porous. His work in pharmacology contributed to the emerging science of drug action, while his clinical teaching brought rigorous diagnostic methods to the study of disorders of the nervous system. The University of Pennsylvania’s departmental archives, which trace the history of its neurology chair from 1871 onward, credit Wood with establishing the institution’s first professorship and chair of neurology, a milestone documented in the broader scholarly literature on early American professorships in neurology by Christopher Goetz and E.J. Pappert.

Wood’s most enduring contribution to the neurological literature came in 1887 with the publication of Nervous Diseases and Their Diagnosis, a treatise issued by the J. B. Lippincott Company of Philadelphia. The book’s subtitle reveals its ambitions: a treatment of the phenomena produced by diseases of the nervous system, with especial reference to the recognition of their causes. At a time when American practitioners relied heavily on European texts, Wood’s treatise represented an effort to systematize neurological diagnosis for an American audience, organizing clinical phenomena according to the underlying lesions and etiologies that produced them. The work placed emphasis on the logical pathway from observed symptoms to anatomical and causal explanations, a mode of reasoning that would become the backbone of clinical neurology as the specialty matured in the twentieth century. Modern historians of movement disorders continue to cite Wood’s clinical descriptions; his observations are referenced in the literature on Meige syndrome, the adult-onset cranial dystonia characterized by blepharospasm and orofacial movements, as scholars such as Mark S. LeDoux and later Pandey and Sharma have traced in the pages of Parkinsonism and Related Disorders and the Journal of the Neurological Sciences.

Wood’s career also intersected with the professional organization that would come to define American neurology. He was a member of the American Neurological Association, founded in 1875, and his name appears in the association’s semi-centennial volume of 1924, where Isaac Abrahamson and T.H. Weisenburg compiled the biographical records of past and present members along with the association’s military history. That membership placed Wood among the small cohort of physicians who, in the closing decades of the nineteenth century, worked to give neurology an institutional identity in the United States, complete with its own societies, journals, and academic chairs. The Goetz and Pappert survey of early American professorships in neurology, published in Annals of Neurology in 1996, situates Wood’s Pennsylvania chair within this wider movement, in which a handful of universities competed to formalize the teaching of nervous diseases.

Beyond his scientific work, Wood left an unexpected mark on the history of American art. He was the subject of a portrait by Thomas Eakins, the great Philadelphia realist painter whose unsparing depictions of surgeons and scientists documented the medical world of his city. Eakins painted several members of the Philadelphia medical establishment, and his portrait of Wood is discussed in the Bulletin of the Detroit Institute of Arts, which holds the work. The painting captures the convergence of art and medicine that characterized Gilded Age Philadelphia, a city where the Pennsylvania Academy of the Fine Arts and the College of Physicians drew from the same social world. For historians, such portraits serve as visual documents of the professional self-image that physicians like Wood cultivated: sober, exacting, and unmistakably modern.

The retrospective on Wood also invites reflection on how the discipline he helped found has changed. When Wood took up his chair in 1871, neurology lacked the electrophysiological, imaging, and molecular tools that define the field today. Diagnosis rested on careful history-taking and physical examination, on the correlation of clinical signs with post-mortem findings, and on the classification of syndromes that could be recognized at the bedside. Wood’s 1887 treatise embodies that approach, and its emphasis on the recognition of causes anticipates the etiological thinking that drives contemporary neurology, even as the technologies of investigation have been transformed beyond anything a nineteenth-century practitioner could have imagined. The continuity, historians argue, lies less in the instruments than in the intellectual discipline of localizing and explaining disease.

Wood’s longevity itself is notable. He lived to 1920, long enough to see neurology acquire laboratory foundations, to witness the rise of bacteriology and the transformation of pharmacology into an experimental science, and to record his memories of the pioneering era in the memoir delivered to the College of Physicians of Philadelphia. Published in the third series of the college’s transactions, the Reminiscences run to more than sixty pages and are now freely accessible through the Internet Archive, allowing a new generation of readers to hear the voice of a man who helped build American experimental medicine from the ground up. The document is prized not only for its factual content but for its window into the culture of nineteenth-century Philadelphia science, its rivalries, its institutions, and its sense of possibility.

Triarhou’s profile, received by the journal in August 2026 and published on 23 September 2026 in volume 273 of the Journal of Neurology, draws on these primary and secondary sources to restore Wood to the prominence he once held. The piece forms part of a series that has documented the lives of the founders of neuroscience across Europe and the Americas, and it situates Wood alongside the other figures whose names are attached to the discipline’s early chairs and societies. The author, who works at the interface of psychology, brain science, and the history of neuroscience, has made a career of such biographical reconstructions, and the Wood article follows the series’ format of combining archival evidence with an assessment of the subject’s scientific contributions.

For modern readers, the story of Horatio C. Wood is a reminder that the institutions of medicine are not timeless but were built, chair by chair and treatise by treatise, by individuals with the energy to imagine them. The first professor of neurology at Penn, the author of a foundational American text on nervous diseases, a pharmacologist, a physician, and a sitter for Thomas Eakins, Wood embodied an era when a single career could span the whole of medical science. His portrait now hangs in the Detroit Institute of Arts; his memoir survives online; his treatise is cited in the histories of dystonia; and his chair, established in 1871, continues as part of one of the leading neurology departments in the United States. Few pioneers leave so many traces across so many fields, and the new profile in the Journal of Neurology ensures that this Philadelphia polymath will not be forgotten by the specialty he helped to create.
