Measuring outcomes and presenting the data clearly are essential to driving quality improvement in healthcare. Florence Nightingale demonstrated this by systematically tracking hospital death rates and using graphical data to reveal where and why deaths were occurring. Her approach wasn't just counting deaths; she analyzed the patterns and created visual tools—most famously the Coxcomb (rose) chart—to show the relationship between sanitation, environment, and patient survival. The striking visuals made the problem undeniable to policymakers and hospital leaders, which spurred reforms in cleanliness, ventilation, nutrition, and overall nursing practices. This data-driven, visualization-led method laid the groundwork for modern quality improvement and epidemiology in healthcare.

The other options miss the mark because they refer to achievements by others or to later innovations: antiseptics were pioneered by Lister, vaccines by Jenner and Pasteur, and electronic health records are a contemporary development not associated with Nightingale.
