The COVID-19 pandemic created an increased demand for healthcare professionals across all healthcare sectors globally. Attrition, retirement, delayed graduations, and sick leaves resulted in an inadequate supply of knowledgeable, skilled, and experienced nurses to care for hospitalized patients and help address hospital capacity pressures. In response to this health human resource crisis in Canada, the Ontario Ministry of Health offered hospitals funding to support the employment of Clinical Externs (CEs), that is, students in nursing, respiratory therapy, physiotherapy, occupational therapy medicine, and paramedicine, hired to work as unregulated staff, alongside an inter-professional team. This mixed-methods study evaluated the CE program that was implemented in one large academic hospital. The primary aim was to identify the outcomes of the clinical extern program from the perspectives of CEs, CE coordinators, and clinical leaders. Findings indicate the clinical extern program reinforces student confidence and supports their transition to formal nursing and respiratory therapy roles.
