What is quaternary prevention?

Quaternary prevention is about protecting patients from the harms of medical overreach. It aims to prevent overmedicalization and unnecessary interventions, ensuring that care given is truly warranted, evidence-based, and aligned with the patient’s values. This differs from primary prevention, which tries to prevent disease from occurring in the first place (reducing incidence); secondary prevention, which involves screening to detect disease early; and tertiary prevention, which focuses on reducing complications and improving function after a disease is established. In practice, quaternary prevention means avoiding unnecessary tests, procedures, or treatments that won’t add value or could cause harm—for example, limiting unnecessary imaging in low-risk situations or avoiding antibiotics for viral illnesses.
