Introduction While ICU clerkships are commonplace in undergraduate medical education, little is known about how students learn there. This study aimed to explore students’ perceptions of the ICU as a learning environment, the factors influencing their learning and any perceived differences between learning in the ICU and non-ICU settings.

Methods We used interpretivist methodology, a social cognitive theoretical framework and a qualitative descriptive strategy. Ten medical students and four graduate doctors participated in four semi-structured focus group discussions. Data were analyzed by six-step thematic data analysis. Peer debriefing, audit trail and a reflexive diary were used.

Results Social cognitive influences on learning were apparent in the discussions. Numerous differences emerged between ICU and non-ICU clinical clerkships, in particular an unfamiliarity with the environment and the complex illness, and difficulty preparing for the clerkship. A key emergent theme was the concept of three phases of student learning, termed pre-clerkship, early clerkship and learning throughout the clerkship. A social cognitive perspective identified changes in learner agency, self-regulatory activities and reciprocal determinism through these phases. The findings were used to construct a workplace model of undergraduate intensive care learning, providing a chronological perspective on the clerkship experience.

Conclusions The ICU, a rich, social learning environment, is different in many respects to other hospital settings. Students navigate through three phases of an ICU clerkship, each with its own attendant emotional, educational and social challenges and with different dynamics between learner and environment.
