PEGASUS was created to help people considering appearance-altering surgery. It’s designed for healthcare professionals to assist patients in making decisions that align with their personal values and goals.
After patients receive information about their options, a specially trained ‘decision coach’ (like a specialist nurse or psychologist) guides them through the PEGASUS process. This helps patients discuss their expectations, allowing the surgeon to determine if they are realistic and address any unrealistic ones, if needed.
PEGASUS has been used with patients considering breast reconstruction or augmentation but is suitable for anyone thinking about surgery that could change their appearance.

“It’s the dialogue that you have that enables them (patients) to move from a really vague idea of something they might want to achieve into operationalising three or four targeted specific goals with clear, you know, measurable ways in which they will now if it’s been successful.”

“Things go round and round and round and in lots of different ways depending on how you are feeling. Getting it down on paper is a completely different matter… it forced me to really think about what I was doing”

The Research
Read More
PEGASUS was developed by a team at CAR after research showed a need for support with decision making about surgery that would alter patients’ appearance. A study at the Royal Free Hospital in 2011 found that PEGASUS was well received by patients and their surgical team.
In 2015, Breast Cancer Now funded a trial to test the PEGASUS intervention for women considering breast reconstruction. Conducted at five NHS sites, the trial involved over 140 women, with 56 receiving PEGASUS. The results showed that PEGASUS helped women focus on their priorities and formulate questions for their healthcare providers. Healthcare professionals also found it useful for understanding each woman’s needs. This study highlighted PEGASUS as a valuable decision-making tool, despite some research challenges.
