Background: Pseudomonas aeruginosa (PA) is a common cause of healthcare-associated infection (PA-HAI) in the intensive care unit (ICU).
Aim: To describe the epidemiology of PA-HAI in ICUs in Ontario, Canada, and to identify episodes of sink-to-patient PA transmission.
Methods: This was a prospective cohort study of patients in six ICUs from 2018 to 2019, with retrieval of PA clinical isolates, and PA-screening of antimicrobial-resistant organism surveillance rectal swabs, and of sink drain, air, and faucet samples.
To compare sensitivity of specimens for COVID-19 diagnosis, we tested 151 nasopharyngeal/midturbinate swab pairs from 117 COVID-19 inpatients using reverse-transcriptase polymerase chain reaction (RT-PCR). Sensitivity was 94% for nasopharyngeal and 75% for midturbinate swabs (P = .0001).

- - A study enrolled 91 COVID-19 patients from 6 hospitals in Toronto to compare testing methods.
- - They tested both nasopharyngeal swabs and saliva samples using RT-PCR to detect the virus.
- - Results showed that nasopharyngeal swabs had a sensitivity of 89%, while saliva had a lower sensitivity of 72%, especially later in the illness (P = .02).
