Recorded live at the World Extreme Medicine Conference in 2023, this session explores the long-term, often intangible impacts of humanitarian aid work — not just on the communities served, but on the volunteers themselves.

Ben LaBrot, founder of Floating Doctors and professor at USC, draws on decades of frontline experience and original research to examine how service work transforms the perspectives, behaviours, and professional paths of volunteers — often years after the fact.

This session explores:

  • The concept of “shadow outputs” and the personal transformations that stem from volunteering

  • How short-term service work creates long-term ripple effects in healthcare careers

  • Emerging data on how humanitarian aid changes confidence, empathy, global stewardship and leadership

  • The importance of mentoring, preparation, and post-deployment integration for volunteers

  • How ethical programme design can maximise meaningful change for both communities and clinicians

Whether you’re just starting out or have years of field experience, this talk invites you to reflect on how volunteer work shapes both medicine and the medic — and why those ripples matter, even decades and continents away.

Intended Learning Outcomes

By the end of this session, participants will be able to:

  1. Define the concept of the “humanitarian butterfly effect” and how volunteer experiences can impact long-term personal and professional development.

  2. Recognise the limitations of traditional metrics (e.g. patient counts) in capturing the full value of humanitarian work.

  3. Identify key personal outcomes commonly associated with service work, including increased empathy, cultural competency, and renewed purpose.

  4. Describe how the structure and delivery of aid programmes can be adapted to enhance both clinical learning and long-term impact.

  5. Reflect on how early-career experiences in aid work influence future career choices and leadership in global health.

  6. Apply ethical considerations in selecting and/or running humanitarian projects, especially with early-stage or student volunteers.
