Percentage of utilization (y-axis) of different staffing resources by the hours of the day as represented by colored boxes along the horizontal axis. The top panel represents the pre–COVID-19 baseline workflow of the center when no technician is needed for COVID-19 testing and screening. The middle panel represents COVID-19 testing and screening with 1 technician, and the bottom panel represents the use of 2 technicians for triage. To maintain throughput at baseline, the working hours of the endoscopy center are lengthened by COVID-19 testing and screening by 3 hours when 1 technician is used and by an hour when 2 technicians are used. Overall, both the middle and bottom panels show decreased staff utilization compared with baseline, except for the triage technicians(s) performing COVID-19 testing and screening. RN, Registered nurse; CRNA, certified nurse anesthetist; CNA, certified nurse assistant; Tech, technicians.
