How Scientific Laboratories Are Adapting to COVID-19 Challenges – Microbiologics Weblog


An Interview with a Diagnostic Laboratory Director

For each main problem of the COVID-19 pandemic, many lesser-known difficulties have multiplied the complexities of laboratory diagnostics. Logistical points, for instance, proceed to affect the pace and effectivity of COVID-19 testing. Though SARS-CoV-2 assays rapidly turned obtainable, laboratories have wanted to repeatedly adapt to new tips and challenges. To higher perceive the lesser-known impacts of the COVID-19 pandemic on medical laboratories, we interviewed John (Jack) Wolk, M.D., Laboratory Director at CareMount Medical, to see how his lab has tailored.

Interview with John (Jack) Wolk, M.D

How has COVID-19 impacted your day by day work atmosphere?

Dr. Wolk: COVID-19 has introduced some main challenges, as you may think about. We should make certain our staff and sufferers are secure with ever altering protocols for approved guests. We’re coping with logistical points, however I’d say the availability chain points have been the largest challenges for a corporation like ours (and possibly all laboratories). These challenges embody something from the lack to supply a key part to the lack to assemble orders at a warehouse. In some circumstances, our main diagnostics distributors have been unable to fulfil orders due to people who find themselves out on quarantine or out for different causes associated to the pandemic. So the availability chain has in all probability been probably the most unpredictable concern with COVID-19.

In fact, the ever-changing panorama of testing has created its personal challenges as a result of new checks have continued to grow to be obtainable proper as much as the current time by FDA processes of Emergency Use Authorization or Emergency Use Notification. Labs should full due diligence to ensure they choose top quality merchandise. A couple of merchandise misplaced their EUAs or needed to modify their EUAs. Thankfully, this didn’t occur with any of our main distributors. CareMount hasn’t had an issue develop with a take a look at after it was put into use, though different laboratories have.

That stated, the opposite problem is that everybody, from the clinicians to our management, desires outcomes at WARP pace. As a take a look at got here out, we needed to speed up our tempo over our regular methodical vetting course of. Usually there’s a stepwise process the place you consider the take a look at. You make certain it’s preforming based on the producer’s specs. Actually, it’s a CLIA and New York State requirement that you just do your individual impartial verification of how the assay is performing. But that is solely step one or two within the strategy of bringing in a take a look at. The take a look at must be built-in into the laboratory info system, so orders could be despatched from the digital medical file and outcomes submitted to the digital medical file as soon as testing is full. The complete strategy of introducing a brand new take a look at was accelerated, the identical approach that COVID vaccine manufacturing was accelerated by doing a number of steps concurrently, as an alternative of sequentially. We have been much less involved with the conventional questions of monetary viability and workflow implications below the idea that, if the take a look at was performing as anticipated based on the producer’s directions to be used, we have been going to make use of it anyway. This strategy allowed us to work on vital LIS and interface steps with out ready to see how the assay carried out in our personal fingers.

Did your lab have to herald devices or checks from outdoors your regular most popular producers, simply to maintain up with all of the COVID testing?

Dr. Wolk: No, we have been lucky in that our platforms got here on-line rapidly. Solely one among our assays modified through the course of, and it modified early within the pandemic. For instance, we have been doing a respiratory multiplex panel even earlier than COVID, which examined for flu, parainfluenza, human metapneumovirus, and even a few bacterial targets like pertussis and parapertussis. Somewhat than wait till that assay producer may introduce COVID-19 PCR into that current panel, which clearly was going to take a while, they launched a standalone COVID-19 take a look at. That was really one of many first PCR checks we have been capable of carry out, and we had it operating by mid- to late-Might of 2020. Within the grand scheme of issues, this was extremely quick, contemplating the pandemic was not formally declared till March.

How is your lab getting ready for the respiratory season this 12 months? How is your preparation this 12 months completely different from final 12 months when COVID was nonetheless pretty new?

Dr. Wolk: We’re stepping into with a greater understanding of the difficulties. We’re higher ready for allocation points, non-reagent shortages within the provide chain, and different logistical challenges. Final 12 months, a vendor had an earthquake close to a distribution middle that delayed shipments. We’re extra agile in our responses to the unexpected.

Do you anticipate performing extra multiplex testing or standalone testing this respiratory season?

Dr. Wolk: I feel we’re going to nonetheless see a good quantity of each as a result of standalone testing and multiplex testing serve completely different functions. We’ll proceed to carry out lots of standalone testing to clear individuals for surgical procedures and to permit individuals to journey, attend occasions, and go to work.

What are some classes that you’ve got realized that you’d be prepared to share with different laboratories to assist them run smoother and extra environment friendly (particularly throughout respiratory season)?

Dr. Wolk: Count on the surprising, and at all times know that, as a lot as you’d prefer to predict the issues earlier than they happen and handle the allocations, there can be surprises. We’ve skilled provide points with reagents, media, swabs, and just about each materials utilized in testing. In a single case, we stocked up on supplies to keep away from shortages, solely to seek out out that among the supplies have been outdated. You additionally should understand that among the individuals now concerned with testing will not be as attentive because the laboratorians who’re educated to handle their testing supplies. For instance, among the medical help employees performing point-of-care checks might not pay as shut consideration to expiration dates. With the added complexity of COVID testing, it’s important to keep looking out for these surprising challenges.
