Introduction:
Preoperative testing for COVID-19 has become widely established to avoid inadvertent surgery on patients with COVID-19 and prevent hospital outbreaks.
Methods:
A prospective cross sectional study was carried out in two university hospitals examining the pre-operative protocols for patients undergoing otolaryngology surgery and the incidence of COVID-19 within 30 days of surgery in patients and the otolaryngologists performing surgery.
Results:
One hundred and seventy-three patients were recruited. One hundred and twenty-three (71%) patients "cocooned" for 14 days prior to surgery. All completed a questionnaire prior to admission. One hundred and fifty-six patients (90%) had reverse transcriptase-polymerase chain reaction (RT-PCR) nasopharyngeal swabs, 14 patients (8%) had CT thorax. No cases of COVID-19 were detected among patients followed up at 30 days. Two surgeons developed COVID-19 early during the study period.
Conclusion:
Current pre-operative testing protocols consisting primarily of questionnaires and RT-PCR resulted in zero cases of COVID in this cohort. It is possible that COVID-19 restrictions and high proportion of patients cocooning preoperatively were factors in ensuring a low rate of COVID-19 post-operatively.
