Unlike many industries, healthcare was simultaneously affected by the COVID-19 pandemic in two opposite ways. On the one hand, the industry faced shortages and overload of many medical representatives such as nurses and infectious disease professionals, but on the other, many medical professionals such as dentists were left with considerably reduced demand. The objective of this paper is to study the efficiency of medical staff allocation and the performance of small and medium sized outpatient clinics in Poland during the COVID-19 pandemic. Owing to the contemporaneity of this problem, we have employed a multiple case study approach. Our sample comprises 5 small and medium-sized outpatient clinics located in Poland in the 3-year period 2019-2021. The results indicate a considerable percentage of medical staff employed in small and medium-sized outpatient clinics remained outside the pandemic, despite their potential provision of healthcare services. Four of the five clinics studied remained passive towards the pandemic. In view of future pandemics, the indications we provide have practical implications for outpatient clinics executives and public health policymakers.
