Becoming a healthcare professional is a complex process, where learning occurs in various ways. This study explores an extracurricular learning approach, called the Social Health Bridge-Building Programme, designed to address health inequities. Student volunteers accompany persons in a socially vulnerable situation to healthcare appointments. Operating outside the realms of health education, the programme intends to provide an alternative road to training healthcare students to become capable of engaging with diverse populations, and reducing barriers to healthcare access. Based on an ethnographic fieldwork, using interviews and participant observation ("walking along") as methods, the aim of the study was to explore the learning processes and learning outcomes associated with bridge-building, as experienced by students. Our findings show that this extracurricular learning complemented the formal curriculum, and bridged the gap from theoretical knowledge to practice and to real persons, preparing students for their future roles. The particular positioning of walking alongside or sitting beside persons made the invisible visible, enabling student volunteers to see the variety of persons in need of bridge-building, ways of living in a socially vulnerable situation, inequity in health, and see the persons, beyond initial impression, fostering a deeper understanding and empathy among the students. Learning outcomes included communicational, relational, and observations skills, and a more comprehensive grasp of the healthcare system's complexity. We conclude that a non-governmental organization, independent of the healthcare system, may have found a novel way of providing extracurricular learning about health inequity to students. Demonstrating how the Social Health Bridge-Building Programme complements formal curricula, the concept could be applicable in other settings.
