The impact of resource allocation during the COVID-19 pandemic on cardiac surgical practice and patient outcomes: a systematic review.

This systematic review examines the impact of resource allocation during the COVID-19 pandemic on cardiac surgery programs and patient outcomes worldwide. It found that the diversion of healthcare resources toward COVID-19 care led to significant reductions in elective cardiac surgeries, increased wait times, and a rise in urgent or emergent procedures, which were associated with higher morbidity and mortality rates. Studies from multiple countries reported decreases in surgical volumes ranging from 21% to over 90%, with some centers closing elective services entirely, resulting in backlogs and worsened patient conditions. The review highlights the need for balanced resource allocation strategies during pandemics to minimize adverse effects on non-COVID patients requiring cardiac surgery and recommends phased resumption of services with ongoing patient monitoring to mitigate long-term negative outcomes.
