AI Article Synopsis
- - This study examines the effectiveness of nasopharyngeal versus tracheal samples in detecting COVID-19 in patients with tracheostomies, conducted at two hospitals from March to June 2020.
- - The research involved a total of 15 patients, with 8 in the experimental group (positive nasopharyngeal test) and 7 in the control group (negative test), using the Abbott RealTime SARS-CoV-2 RNA assay for testing.
- - Results showed that the average viral shedding duration was about 20.9 days, and only 6.7% of patients tested positive in tracheal samples after a negative test from nasopharyngeal samples, indicating high correlation
Article Abstract
This study compares nasopharyngeal and tracheal samples for COVID-19 viral testing in patients with a tracheostomy. This was a prospective cohort study done at 2 academic hospitals between March and June 2020. Patients admitted through the emergency department who had a COVID-19 test and an existing tracheostomy or underwent a tracheostomy during the admission period were included. Patients with a positive initial nasopharyngeal swab were placed in the experimental group (n = 8), while those with a negative swab were the control group (n = 7). Nasopharyngeal and tracheal samples underwent COVID-19 testing using the Abbott RealTime SARS-CoV-2 RNA assay. Fourteen patients underwent tracheostomy, and 1 had an existing tracheostomy. The average duration of viral shedding in nasopharyngeal samples was 20.9 days. One patient (6.7%) tested positive in tracheal secretions after a negative nasopharyngeal swab. In the remaining patients (93.3%), the nasopharyngeal and tracheal specimens correlated.
