Florence Nightingale had a significant impact on nursing and healthcare in the 19th century through establishing nursing as a respected profession, advocating for hygienic hospital conditions, and founding nursing schools. However, some of her views such as opposition to nurse registration and emphasis on social class are now considered outdated. While still an iconic figure, modern scholarship has also revealed flaws in her character such as exaggerating her own accomplishments and bullying behaviors. Overall, Nightingale's emphasis on clinical practice and education remain relevant today, but some of her specific opinions are no longer applicable in the 21st century healthcare system.
