Purpose
To analyze emergency department (ED) computerized tomography (CT) utilization in cancer patients with coronavirus disease 2019 (COVID-19).
Methods
A retrospective chart review was performed to identify cancer patients who received COVID-19 diagnosis within the single healthcare system and presented to the ED within 30 days of COVID-19 positive date between May 1 and December 31, 2020.
Results
In our 61 patients, the mean age was 72.5 years old, with 34% of patients (
n
= 21) on active cancer therapy and 66% (
n
= 40) on surveillance only. Most patients (
n
= 53) received their COVID-19 diagnosis within the ED, with 8 patients diagnosed prior to initial ED visit. The most common CT studies ordered within the ED were CT chest (
n
= 25), CT abdomen/pelvis (A/P) (
n
= 20), CT head (
n
= 8), and CT chest/abdomen/pelvis (C/A/P) (
n
= 7). COVID-19 findings were present on 33 scans, findings of worsening malignancy on 12 scans, and non-COVID non-cancer findings on 9 scans. Significant differences in CT severity score (
p
= 0.0001), indication for hospitalization (
p
= 0.026), length of hospitalization (
p
= 0.004), interventions (remdesivir, mechanical ventilation, and vasopressor support) while hospitalized (
p
< 0.05), and mortality (
p
= 0.042) were found between the prior diagnosis and ED diagnosis groups. No such differences were found between the active treatment and surveillance groups.
Conclusion
ED CT imaging findings in patients with cancer and COVID-19 are predominantly related to COVID-19 infection, rather than cancer history or anti-cancer therapy status.
