Impact of COVID-19 on a medium-sized travel medicine clinic in eastern Pennsylvania, USA.

Background: The COVID-19 pandemic (COVID) disrupted international travel. We sought to determine the impact of the COVID-19 pandemic on patient volume, traveler demographics, and income of our medium-sized travel clinic in Pennsylvania, USA.

Methods: We extracted de-identified pre-travel data on 3,510 pre-travel consultations for adults during: Pre-COVID-19 (January 2018-December 2019), Early COVID-19 (April 2020-March 2022) and Late COVID-19 (April 2022-March 2023). We compared traveler demographics, destinations, purpose of travel, medical conditions, and number of vaccinations administered over time, and our clinic's revenue obtained from our financial database (TruSource) for the Pre, Early and Late COVID-19 periods.

Results: We observed 84% and 85% relative decreases in traveler volume and revenue respectively from the Pre-COVID-19 to the Early COVID-19 period. The decrease (16-11%) in volume was highest for travelers over 65 years of age. Of those that sought care during Early COVID-19, a fewer proportion of travelers had multiple co-morbid conditions and were taking chronic medications. Trip length increased and there was a significant increase in travel to Africa. Travel to visit friends or family and for service work also increased during Early-COVID-19 (32.9%) versus Pre-COVID-19 (19.8%). Clinic volume and revenue began to increase in Late COVID-19 but did not return to Pre-COVID levels.

Conclusions: The COVID pandemic resulted in a large reduction in patient volume and revenue in our academic-based Pennsylvania travel clinic. We saw substantial changes in our traveler demographics, destinations, as well as reasons and durations of travel. Smaller travel clinics will need to have plans in place in order to survive the next pandemic and better serve their pre-travel populations.
