COVID-19 NEWS Put to the Test How quickly could the hospital stand up a process to test for COVID-19? As the novel coronavirus began to rapidly spread in early 2020, Children’s Hospital Colorado infectious disease specialist Samuel Dominguez, MD, PhD, and his team knew it was likely only a matter time before it became a global pandemic. The hospital would need to quickly bring its own assay online to effectively manage its patients. It was the first clinical lab in Colorado to do so and one of the first in the nation. ASSESSING THE SITUATION Dr. Dominguez has a clinical interest in emerging pathogens. In fact, before he took over as medical director of the Children’s Colorado microbiology lab in 2016, he worked on basic science research related to coronaviruses. “Our whole team had been watching this scenario closely since late 2019,” he says. “In early January 2020, we went to hospital leadership and expressed how we needed to start thinking about what our response was going to be and how we could prepare, including what it would take to bring an assay online.” Then, on January 20, 2020, Washington State reported the U.S.’s first confirmed case of COVID-19. That accelerated an already unprecedented preparation timeline. There were two options. Dr. Dominguez and his team could try to build an assay from scratch — what’s known as a laboratory developed test, or LDT. Historically, though, it takes months to progress through necessary government approvals. Labs have to prove the test meets appropriate standards for sensitivity, specificity and limits of detection. Was that even possible in weeks? The other option was to use the assay already in development by the Centers for Disease Control and Prevention, or CDC, but at the time, it was only available for use by state public health labs. “It really left clinical labs in a bind,” says. Dr. Dominguez. “So we went back to hospital leadership and asked for guidance on how to proceed.” Hospital leadership connected the epidemiology team with the Children’s Colorado legal and government affairs teams to find a way to fast track the process. TIME TO TAKE ACTION The government affairs team lobbied the governor of Colorado and members of congress to speak with the FDA about lifting regulatory barriers. As it turned out, other labs across the country were doing the same in their respective states. Mounting pressure led the FDA to issue an emergency use authorization allowing highcomplexity, CLIA-certified labs to use the CDC assay, provided those labs had particular reagents, extraction kits, probes and enzymes to run the assay. That was another roadblock. “We got approval to move forward, but there were supply chain barriers,” says Dr. Dominguez. “We didn’t have access to those resources and neither did other labs.” But they had plenty of the reagents they typically use, which meant that the government affairs team needed to lobby for additional approval. “We were willing to do our own validation and verification to show that the extraction agents we had on hand were equivalent,” he says. “We’d do whatever was necessary to get this assay up and running.” That determination paid off. They secured quick approval, and on March 16, Children’s Colorado was the first hospital in Colorado to have an assay up and running. Not only could they run samples from team members and patients in-house, it was a service they began to offer community hospitals around the region — including some from Wyoming and Montana. 4 | CHILDREN’S HOSPITAL COLORADO
