Her use of mathematical and statistical data to show the relevance of her findings; that environmental factors can, and do influence patient’s rate of recovery was the beginning of nursing research and science as it is known today. One could almost imply that Nightingale knew that outcome measures needed to be “relevant, and address both the constant and variable components in order to determine effectiveness of an outcome” (Blackwood, 2006).
