The transfusion service laboratory in virtual reality.

Due to the global SARS-CoV-2 pandemic, in-person laboratory medicine clerkships were converted to distance learning. The remote clerkship format provided advantages of allowing participation of students from more locations and greater scheduling flexibility but provided new challenges of maintaining learner engagement and providing experiential content of the laboratory environment. Gamification of educational content is one educational modality that has shown effectiveness in a multitude of different contexts to increase learner engagement and retention. Therefore, we created an interactive, educational 360° virtual reality walkthrough tour using off-the-shelf commercially available 360° cameras and software of the Transfusion service and Microbiology Laboratories. The process consists of taking multiple 360° still-images within the space, color-correction, blurring the faces of staff or sensitive information, adding navigation buttons, and other interactive elements. The virtual tours were used for both recruitment and education with further plans to integrate the learning modality into the curriculum. The clerkship is likely to remain as partially or fully as remote learning so such walkthrough tours will continue to remain relevant. This technology can be applied globally to other departments and institutions for education or recruitment.

Coping With COVID-19.

OBJECTIVES: The first coronavirus disease 2019 (COVID-19) case in the United States was reported in Washington State. The pandemic caused drastic disruptions to medical institutions, including medical education. The Department of Laboratory Medicine at the University of Washington responded by rapidly implementing substantial changes to medical student clerkships. METHODS: In real time, we converted one ongoing case- and didactic-based course, LabM 685, to remote learning. RESULTS: Fifteen of 17 scheduled sessions proceeded as planned, including two sessions for student presentations. Two didactics were canceled as the functions of the teleconferencing platform were not sufficient to proceed. One grand rounds speaker canceled due to COVID-19 precautions. Elements of an immersive clinical laboratory clerkship, LabM 680, were repurposed to accommodate 40 medical students per class via remote learning, highlighting clinical laboratory activities that continue throughout the outbreak. A new remote clerkship, MedSci 585C, was developed incorporating distance learning and guided small-group sessions. This coincided with parallel efforts to make resident and fellow service work, conferences, and didactics available remotely to comply with social distancing. CONCLUSIONS: The changes in medical education described reflect the dynamic interplay of current events affecting the world of clinical pathology. Throughout this, technology-while with some limitations-has provided the platform for innovative learning.

Comparison of Commercially Available and Laboratory-Developed Assays for In Vitro Detection of SARS-CoV-2 in Clinical Laboratories.

Multiple laboratory-developed tests (LDTs) and commercially available assays have emerged to meet diagnostic needs related to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. To date, there is limited comparison data for these different testing platforms. We compared the analytical performance of a LDT developed in our clinical laboratory based on CDC primer sets and four commercially available, FDA emergency use authorized assays for SARS-CoV-2 (Cepheid, DiaSorin, Hologic Panther, and Roche Cobas) on a total of 169 nasopharyngeal swabs. The LDT and Cepheid Xpert Xpress SARS-CoV-2 assays were the most sensitive assays for SARS-CoV-2 with 100% agreement across specimens. The Hologic Panther Fusion, DiaSorin Simplexa, and Roche Cobas 6800 failed to detect positive specimens only near the limit of detection of our CDC-based LDT assay. All assays were 100% specific, using our CDC-based LDT as the gold standard. Our results provide initial test performance characteristics for SARS-CoV-2 reverse transcription-PCR (RT-PCR) and highlight the importance of having multiple viral detection testing platforms available in a public health emergency.

Laboratory Perspective on Racial Disparities in Sexually Transmitted Infections.

BACKGROUND: Rates of sexually transmitted infections (STI) have risen steadily in recent years, and racial and ethnic minorities have borne the disproportionate burden of STI increases in the United States. Historical inequities and social determinants of health are significant contributors to observed disparities and affect access to diagnostic testing for STI. CONTENT: Public health systems rely heavily on laboratory medicine professionals for diagnosis and reporting of STI. Therefore, it is imperative that clinicians and laboratory professionals be familiar with issues underlying disparities in STI incidence and barriers to reliable diagnostic testing. In this mini-review, we will summarize contributors to racial/ethnic disparity in STI, highlight current epidemiologic trends for gonorrhea, chlamydia, and syphilis, discuss policy issues that affect laboratory and public health funding, and identify specific analytic challenges for diagnostic laboratories. SUMMARY: Racial and ethnic disparities in STI in the US are striking and are due to complex interactions of myriad social determinants of health. Budgetary cuts for laboratory and public health services and competition for resources during the COVID-19 pandemic are major challenges. Laboratory professionals must be aware of these underlying issues and work to maximize efforts to ensure equitable access to diagnostic STI testing for all persons, particularly those most disproportionately burdened by STI.

Expedited SARS-CoV-2 screening of donors and recipients supports continued solid organ transplantation.

Universal screening of potential organ donors and recipients for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is now recommended prior to transplantation in the United States during the coronavirus disease 19 (COVID-19) pandemic. Challenges have included limited testing capacity, short windows of organ viability, brief lead time for notification of potential organ recipients, and the need to test lower respiratory donor specimens to optimize sensitivity. In an early U.S. epicenter of the outbreak, we designed and implemented a system to expedite this testing and the results here from the first 3 weeks. The process included a Laboratory Medicine designee for communication with organ recovery and transplant clinical staff, specialized sample labeling and handoff, and priority processing. Thirty-two organs recovered from 14 of 17 screened donors were transplanted vs 70 recovered from 23 donors during the same period in 2019. No pretransplant or organ donors tested positive for SARS-CoV-2. Median turnaround time from specimen receipt was 6.8 hours (donors), 6.5 hours (recipients): 4.5 hours faster than daily inpatient median. No organ recoveries or transplantations were disrupted by a lack of SARS-CoV-2 testing. Waitlist inactivations for COVID-19 precautions were reduced in our region. Systems that include specialized ordering pathways and adequate testing capacity can support continued organ transplantation, even in a SARS-CoV-2 hyperendemic area.
