ABSTRACT
BACKGROUND: Irish health services have been repurposed in response to the COVID-19 pandemic. Critical care services have been re-focused on the management of COVID-19 patients. This presents a major challenge for specialities such as cardiothoracic surgery that are reliant on intensive care unit (ICU) resources. AIM: The aim of this study was to evaluate the impact of the COVID-19 pandemic on activity at the cardiothoracic surgical care at the National Cardiothoracic Surgery and Transplant Centre. METHODS: A comparison was performed of cardiac surgery and transplant caseload for the first 4 months of 2019 and 2020 using data collected prospectively on a customised digital database. RESULTS: Cardiac surgery activity fell over the study period but was most impacted in March and April 2020. Operative activity fell to 49% of the previous years' activity for March and April 2020. Surgical acuity changed with 61% of all cases performed as inpatient transfers after cardiology admission in contrast with a 40% rate in 2019. Valve surgery continued at 89% of the expected rate; coronary artery bypass surgery was performed at 61% of the expected rate and major aortic surgery at 22%. Adult congenital heart cases were not performed in March or April 2020. One heart and one lung transplant were performed in this period. CONCLUSIONS: In March and April of 2020, the spread of COVID-19 and the resultant focus on its management resulted in a reduction in cardiothoracic surgery service delivery.
