{Reference Type}: Case Reports {Title}: Availability Bias and the COVID-19 Pandemic: A Case Study of Legionella Pneumonia. {Author}: Kyere K;Aremu TO;Ajibola OA; {Journal}: Cureus {Volume}: 14 {Issue}: 6 {Year}: Jun 2022 暂无{DOI}: 10.7759/cureus.25846 {Abstract}: Cognitive biases, such as the availability heuristic or availability bias, can inadvertently affect patient outcomes. These biases may be magnified during times of heightened awareness of a particular disease. Failure to identify cognitive biases when managing patients during the coronavirus disease 2019 (COVID-19) pandemic can delay the institution of the right treatment option and result in poor health outcomes. We present a case of delayed diagnosis of Legionella pneumonia due to COVID-19-related availability bias. We discuss some methods to mitigate the effects of this bias and the importance of challenging trainees to recognize these pitfalls in medical training.
