Quaternary prevention and its implications for the clinical practice: a systematic review

Abstract

The growing production regarding iatrogenesis justifies the discussion about the incorporation of quaternary prevention in the daily medical practice. This study identified and systematized the production of knowledge about quaternary prevention and its implications for the clinical practice. This is a systematic descriptive review supported by the guiding question: What evidence has been produced regarding quaternary prevention and its impact on the clinical practice? A bibliographic survey was carried out between August and September 2020 using the descriptor “quaternary prevention” in English, Portuguese and Spanish. The analysis of 30 articles produced evidence on potentially harmful medical interventions that would justify the adoption of quaternary prevention. The study invites the medical community to reflect on the incorporation of quaternary prevention, aiming for a less iatrogenic care practice, valuing person-centered medicine and the attributes of primary health care.
