[Quaternary prevention in the elderly]

Area of Science:

• Medical Ethics
• Public Health
• Clinical Practice

Context:

• Healthcare activities inherently carry risks alongside benefits.
• A dynamic balance between benefit and harm necessitates continuous clinical assessment.
• Unnecessary medical interventions can lead to patient harm.

Purpose:

• To define and illustrate quaternary prevention strategies.
• To emphasize the importance of avoiding unnecessary medical activities.
• To encourage ongoing assessment of quaternary prevention in daily practice.

Summary:

• Quaternary prevention involves measures to prevent, decrease, or alleviate harm from healthcare activities.
• Examples include avoiding unnecessary screenings (e.g., prostate cancer), judicious antibiotic use, and appropriate rehabilitation.
• It also encompasses limiting harm from interventions like physical movement restriction devices in the elderly.

Impact:

• Promotes patient safety by reducing iatrogenic harm.
• Encourages evidence-based medicine and efficient healthcare resource allocation.
• Reinforces the ethical imperative of "first, do no harm" in clinical decision-making.
