SARS-COV-2 SEROPREVALENCE AMONG EMERGENCY PROVIDERS AND THE IMPORTANCE OF PERSONAL PROTECTIVE EQUIPMENT.
Background: Healthcare workers (HCWs) have elevated exposure risks to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, there is limited published information regarding the transmission rate and the seroconversion among HCWs. The goals of this study are to determine the seroprevalence among emergency providers and the correlation between working hours and utilization of personal protective equipment with the likelihood of seroconversion. Methods: This prospective study evaluated Emergency Department physicians and advanced practice providers, who had been tested for SARSCoV-2 IgG serology, at 10 different hospitals in the location area. An anonymous survey was sent to the Emergency Department providers via email inquiring about the following: results of serology and/or nasopharyngeal testing, the testing site used, the presence or absence of COVID-19 symptoms, utilization of personal protective equipment (PPEs), exposure to potential COVID-19 patients, and average clinical hours since March. Results: 43 participants responded to the survey. 3 had positive SARS-CoV-2 antibody or viral tests indicating exposures to COVID-19 despite utilization of various types of PPE. There was a surprisingly high number of HCWs treating known/suspected COVID-19 patients without proper PPE (18.6%). 21 (48.8%) HCWs routinely wore an N-95 mask, 11 (25.6%) used a powered air-purifying respirator (PAPR), 6 (14%) wore surgical masks, and 5 (11.6%) used elastomeric face respirators. None of the COVID-19 positive HCWs used a PAPR while treating known or suspected COVID-19 patients. Conclusion: Our knowledge regarding the complications related to SARS-CoV-2 infection post-acute phase remains limited. Our data suggest PAPR use may be protective compared to other PPE modalities. There can be unanticipated long-term morbidities that result from an infection with SARS-CoV-2. Therefore, frontline HCWs, who have an inherently elevated exposure to this virus, must use PPE and maintain vigilance while treating patients, regardless of the presence of COVID-19 symptoms.
