Analysis of Incidentally Diagnosed Patients with Coronavirus Disease 2019 at the Emergency Department: Single-Center Clinical Experience.

Objective: Asymptomatic patients with coronavirus disease 2019 can present with signs of various diseases to hospitals. We aimed to present patients who presented to the emergency department without any coronavirus disease 2019 symptoms and were incidentally diagnosed with coronavirus disease 2019 in addition to the diagnosis related to their complaints on presentation.

Materials and methods: The study included patients presented to the emergency department of a hospital in Erzurum (Turkey) with non-coronavirus disease 2019 symptoms and were incidentally diagnosed with coronavirus disease 2019 on the basis of their chest computed tomography findings. The patients' primary diagnoses were evaluated, and a reverse transcriptase-polymerase chain reaction was performed to confirm the incidental coronavirus disease 2019 diagnoses.

Results: The 42 patients included in the study had various complaints, and the most common complaint was abdominal pain in 8 patients (19%). The other complaints were at different rates. The most common diagnose was ST-elevated myocardial infarction in 6 patients (14.3%), and the other diagnoses were rib fracture in 3 patients (7.1%) and other similar diseases in the remaining patients.

Conclusion: Patients with highly the contagious coronavirus disease 2019 can sometimes be asymptomatic and can be incidentally diagnosed with coronavirus disease 2019 after presenting to emergency departments with symptoms and manifestations other than those of coronavirus disease 2019. Therefore, healthcare professionals working in the emergency department should approach all patients who present to the emergency service as potential coronavirus disease 2019 carriers and wear their protective equipment and take necessary precautions.
