Total new significant respiratory cultures in each 6-month block before the pandemic (March 2016 to March 2020) and the 6-month block during the pandemic. Identification of clinically significant new organisms dropped from a mean of 13 per 6-month period in 102 individuals before the pandemic to 3 during the pandemic (odds ratio of new significant organism identification during the pandemic compared with prepandemic 6-monthly mean = 0.21; 95% confidence interval, 0.04–0.79; P = 0.016 by Fisher’s exact test). Achromo = Achromobacter xylosoxidans; BC = Burkholderia Cepacia complex; MRSA = methicillin-resistant Staphylococcus aureus; PA = Pseudomonas aeruginosa; Steno = Stenotrophomonas maltophilia.
