Maria Llargués Pou, a soon-to-be Family Physician in Barcelona, recently shared with me her Bachelor's Thesis.
Her work - "Primum non nocere" Preventing Overdiagnosis, the Quaternary Prevention provides a concise introduction to the efforts around the world to prevent overuse of tests, treatments, and disease-labels, as well as the reasons we must address this growing issue.
Llargués Pou has beautifully laid out an evolution of ideas, from Ivan Illich's idea of Iatrogenesis, to Jamoulle's attempts to thwart iatrogenic harm with a public health model of Quaternary Prevention, and now, contemporary efforts to tackle overdiagnosis, like the Choosing Wisely Campaign and Preventing Overdiagnosis conference. Her paper serves as a great "backgrounder" for those who wish to learn more about the broad themes and history of this movement.
