To address a pandemic, preserving and maintaining the healthcare system’s capacity is critical. This Commentary evaluates factors contributing to healthcare labour shortages and investigates the inter-relationships between access to health services, the number of healthcare providers, compensation rates and migration patterns. Addressing healthcare access challenges likely requires increasing the number of healthcare providers and also addressing inefficiencies in the combination of inputs – the mix of providers, facilities, tools and equipment. Overall, the results suggest a critical and strategic examination of fee schedules for physician services, with the goal of reducing the average cost per service but strategically increasing remuneration for difficult-to-access services. Nurses and other care providers can increase the efficiency of healthcare delivery through expanding scopes of practice or filling gaps when there is a shortage of family or specialist physicians. However, there are, as well, shortages of nurses and other healthcare providers. Another example of increasing the efficiency of healthcare services is the shift toward team-based care. A critical feature of both expanding scopes of practice and team-based care is effective communication and knowledge transfer between supervising specialists and care providers. The time and costs associated with training new physicians make it infeasible to address labour shortages arising from a crisis or an unexpected population need simply through training more of the needed physicians. However, shifting methods and modes of care delivery, or adapting scopes of practice, are tools to address short-term healthcare labour supply gaps. Over the longer term, increasing the efficiency and supply of healthcare labour will require adapting medical education policies, remuneration and entry pathways to practising medical professions, as well as continuing to modernize care delivery methods, coordination and health data accessibility.
