Abstract and Introduction

Abstract

Background: Health care professionals (HCPs) performing tracheostomies in patients with COVID-19 may be at increased risk of infection.

Objective: To evaluate factors underlying HCPs' COVID-19 infection and determine whether tracheostomy providers report increased rates of infection.

Methods: An anonymous international survey examining factors associated with COVID-19 infection was made available November 2020 through July 2021 to HCPs at a convenience sample of hospitals, universities, and professional organizations. Infections reported were compared between HCPs involved in tracheostomy on patients with COVID-19 and HCPs who were not involved.

Results: Of the 361 respondents (from 33 countries), 50% (n = 179) had performed tracheostomies on patients with COVID-19. Performing tracheostomies on patients with COVID-19 was not associated with increased infection in either univariable (P = .06) or multivariable analysis (odds ratio, 1.48; 95% CI, 0.90–2.46; P = .13). Working in a low- or middle-income country (LMIC) was associated with increased infection in both univariable (P < .001) and multivariable analysis (odds ratio, 2.88; CI, 1.50–5.53; P = .001).

Conclusions: Performing tracheostomy was not associated with COVID-19 infection, suggesting that tracheostomies can be safely performed in infected patients with appropriate precautions. However, HCPs in LMICs may face increased infection risk.

Introduction

SARS-CoV-2, the virus responsible for COVID-19, had claimed more than 6 million lives by early August 2022.[1] Health care professionals (HCPs) who treat patients who test positive for COVID-19 are at increased risk of infection relative to the general population, with the incidence of HCP infection as high as 38%.[2–5] However, the factors associated with risk of COVID-19 infection among HCPs overall, and specifically among HCPs involved in aerosol-generating procedures such as tracheostomy, remain poorly characterized.[6]

Between 17% and 24% of patients admitted for COVID-19 treatment require invasive mechanical ventilation.[7–9] Early tracheostomy in intubated patients has been associated with shorter stays in the intensive care unit outside the context of the pandemic and shorter duration of invasive mechanical ventilation in patients who test positive for COVID-19 specifically.[10–13] Optimizing utilization of scarce resources has been critical to health care system stability during the pandemic, and appropriately timed tracheostomy may facilitate this goal as COVID-19 shifts to an endemic problem.[14,15]

Factors associated with risk of COVID-19 infection among health care providers, especially those involved in tracheostomy procedures, remain poorly characterized.

SARS-CoV-2 is transmitted through inhalation or mucous membrane contact with droplets and aerosols.[16,17] Because of the nature of the tracheostomy for patients who test positive for COVID-19 may face additional risks because of aerosolization of viral particles.[6] For this reason, experts have proposed numerous aerosol-minimizing techniques, although evidence regarding the efficacy of those techniques remains scant.[15,18–26] Given concern about the added risk of infection among HCPs, several expert organizations have recommended delaying tracheostomy 14 to 21 days after intubation or deferring procedures entirely,[27–31] despite reports of low rates of COVID-19 infection among tracheostomy providers.[32,33]

Considering the knowledge gaps surrounding HCP COVID-19 infections, particularly among HCPs involved in tracheostomy procedures, we sought to determine what clinical factors are associated with risk of COVID-19 infection in a global HCP population. We hypothesized that HCPs involved in tracheostomy procedures would report greater rates of COVID-19 infection than other HCPs.
