Whose decision is it? The microstructure of medical decision making

Area of Science:

• Medical Ethics
• Decision Science
• Oncology

Background:

• Medical decision-making is often oversimplified as solely patient or physician-driven.
• The influence of social networks (family, friends, other professionals) is frequently overlooked.
• Complex medical choices require a nuanced understanding beyond a two-dimensional model.

Purpose of the Study:

• To illustrate the multifaceted nature of medical decision-making.
• To highlight the role of social context in patient choices.
• To introduce the concept of decision "microstructure" for better analysis.

Main Methods:

• Case study analysis of a teenager with cancer considering chemotherapy cessation.
• Qualitative exploration of the decision-making process.
• Conceptual framework development of decision microstructure.

Main Results:

• The decision-making process involved multiple stakeholders beyond the patient and physician.
• The patient's decision evolved through identifiable substeps, revealing its microstructure.
• Physician involvement was crucial but adaptable to patient autonomy.

Conclusions:

• Medical decisions are complex, dynamic, and influenced by a wider social network.
• The concept of decision microstructure provides a valuable analytical tool.
• Physicians can effectively guide patients through complex decisions while respecting their autonomy.
