Florence Nightingale's contributions to modern nursing practices were groundbreaking and laid the foundation for professional nursing. Her work during the Crimean War highlighted the importance of sanitation, hygiene, and patient care, drastically reducing mortality rates in military hospitals. Nightingale introduced evidence-based practices and emphasized the need for trained nurses, advocating for the establishment of formal nursing education. Her use of statistical analyses to demonstrate the link between proper sanitation and patient outcomes transformed healthcare practices. Nightingale's pioneering efforts not only revolutionized nursing but also established it as a respected profession in the medical field.
