What is the third stage of the four stages of prevention?

• A. Providing optimal health to prevent further disease progression
• B. Preventing healthcare-associated complications
• C. Early identification and treatment
• D. Preventing altogether

Answer: (A)

In the four-stage model of prevention, the third stage focuses on reducing damage and preventing further progression after a disease or injury has already occurred. Providing optimal health to prevent further disease progression describes this aim, because the interventions are about minimizing complications, restoring function, and slowing deterioration through rehabilitation and ongoing management. Early identification and treatment represents secondary prevention, aimed at catching disease early to prevent progression. Preventing altogether is primary prevention, aimed at stopping disease from occurring in the first place. Preventing healthcare-associated complications is a safety goal within care, not a named prevention stage.
