Dynamic Instrument Mixes in Professional Regulation and the Navigation Burden on Internationally Educated Health Professionals: Comparative Lessons From Four Jurisdictions

Regulation and policy instruments governing health professions seek to balance professional autonomy and public protection. However, they can create legacy effects, uneven entry pathways, stratified practice rights, and redistributed risks and costs. How policy instruments interact and shape outcomes within complex health professional regulatory systems remains understudied. Relying on a policy instruments approach, this study analyzes documentary evidence and 45 semi-structured interviews across England, Scotland, Ontario, and Nova Scotia between 2000 and 2020, and the early parts of the COVID-19 pandemic. Instruments are classified using cultural theory and examined for effectiveness, efficiency, and equity. The findings show that professional healthcare regulation and its instruments have constantly evolved, often creating trade-offs in achieving regulatory goals. Given their limited institutional influence, internationally educated professionals bore disproportionate burdens. Therefore, this study advocates that regulators must balance responsiveness with predictability to protect the public while enabling fair, transparent, and sustainable pathways into professional practice.
