Death by Rousui in Japan: Rethinking Death, Diagnosis, and Care in an Aging Society.

Area of Science:

• Gerontology
• Palliative Care
• Public Health

Background:

• Old age (rousui) is the third leading cause of death in Japan, officially recognized on death certificates.
• Rousui signifies a gradual, multidimensional decline in physiological function without a specific underlying disease.
• Culturally accepted in Japan, rousui lacks a clear clinical definition, leading to diagnostic and care uncertainties.

Purpose of the Study:

• To discuss the clinical implications of recognizing death from old age (rousui) in Japan.
• To explore the challenges in diagnosing and managing patients experiencing rousui.
• To propose a framework for recognizing and caring for individuals dying from aging itself.

Main Methods:

• Case study of a family physician's experience diagnosing rousui in a patient in her 90s.
• Analysis of the cultural acceptance and clinical ambiguity surrounding rousui.
• Review of end-of-life decision-making influenced by the concept of rousui.

Main Results:

• Rousui is a significant cause of death, yet remains clinically undefined.
• Ambiguity in rousui diagnosis leads to potential overmedicalization or undertreatment.
• Japan's experience provides insights into managing age-related decline and death.

Conclusions:

• There is a need for standardized clinical definitions and care protocols for rousui.
• Aligning medical practice with the natural end of life is crucial as global populations age.
• Further discussion is needed on integrating the concept of dying from aging into mainstream medicine.
