In 1915 when Yale added the Department of Public Health to its medical school, such programs were rare. The University of Pennsylvania had one. Harvard and MIT had a joint School for Health Officers. Johns Hopkins was a year away from starting its School of Hygiene and Public Health. As suggested by these names, the field was still finding its identity. Yale considered naming its department “Public Health and Public Service” or “Hygiene and Philanthropy.”

The new professorship at Yale was endowed by the family of Anna M.R. Lauder. The money came with conditions. The appointee had to be a physician with experience in public health and sanitary science and also had to be willing to enter the political fray and bring about change in the state’s public health regulations. The university was wise enough to ignore the stipulation requiring a physician, instead hiring a 38-year-old bacteriologist named Charles-Edward Amory Winslow. He turned out to be an inspired choice beyond anyone’s expectations, except perhaps his own.

Public health is “the science and art of preventing disease, prolonging life, and promoting health through the organized efforts and informed choices of society, organizations, public and private communities, and individuals.” — CEA Winslow

EMS is considered to be a component of public health. Where injury and illness prevention is not typically a component of EMS operations, EMS can fulfil the need for early intervention. In many areas, EMS is the primary connection between the hospital system and the public. Some EMS agencies actively participate in primary prevention by way of vaccination and public education. The primary role for EMS is secondary prevention. Secondary prevention is the act of preventing the complications or slowing the progression of a disease.

Unbeknownst to most EMS providers, they are participating in disease surveillance. Every patient care report has the ability to be queried for patterns. The analysis of patterns is often referred to as syndromic surveillance. EMS providers are first line providers; as such provides the best source of information for analysis of data as it pertains to health and the general public. Trauma is a disease that is best prevented. Understanding how trauma happens is a goal of public health. Typical information gleaned from EMS reports in regards to trauma are:

• Car seat safety
• Seat belt usage
• Helmet usage
• Driving under the influence
• Falls
• Fire
