Comparison of Two Commercial Platforms and a Laboratory-Developed Test for Detection of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) RNA.

Mitigation of the ongoing coronavirus disease 2019 (COVID-19) pandemic requires reliable and accessible laboratory diagnostic services. In this study, the performance of one laboratory-developed test (LDT) and two commercial tests, cobas SARS-CoV-2 (Roche) and Amplidiag COVID-19 (Mobidiag), were evaluated for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA in respiratory specimens. A total of 183 specimens collected from suspected COVID-19 patients were studied with all three methods to compare their performance. In relation to the reference standard, which was established as the result obtained by two of the three studied methods, the positive percent agreement was highest for the cobas test (100%), followed by the Amplidiag test and the LDT (98.9%). The negative percent agreement was lowest for the cobas test (89.4%), followed by the Amplidiag test (98.8%), and the highest value was obtained for the LDT (100%). The dilution series of positive specimens, however, suggests significantly higher sensitivity for the cobas assay in comparison with the other two assays, and the low negative percent agreement value may be due to the same reason. In general, all tested assays performed adequately. Clinical laboratories need to be prepared for uninterrupted high-throughput testing during the coming months to mitigate the pandemic. To ensure no interruption, it is critical that clinical laboratories maintain several simultaneous platforms in their SARS-CoV-2 nucleic acid testing.

Delivering a one-stop, integrated, and patient-centered service for patients with rheumatic diseases.

OBJECTIVE: To describe a one-stop, integrated rheumatology service and assess patient satisfaction. METHODS: A descriptive report and patient satisfaction survey of a rheumatology clinic model first developed in 1996 to enhance the patient "journey" through rheumatology services. A patient-satisfaction survey over a 3-week period assessed several aspects of care including quality of services, consultations, and patient education. RESULTS: All referrals are screened by a rheumatologist to pre-schedule laboratory/radiology/other tests for the visit. Upon arrival to the clinic, patients check-in at an electronic desk, and then complete the electronic GoTreatIT monitoring system which assesses patient-reported outcomes. The patient is reviewed by a doctor in a 30- to 60-min consultation, and then by a nurse (for diagnosis/treatment education, vaccinations). An ultrasound machine and capillaroscopy are available for use in the clinic. Patients can be scheduled on the same day to see a nutritionist, physiotherapist, or other heath professionals as necessary. An "early-rheumatoid arthritis treatment path" is available to ensure early, intensive treatment. A patient satisfaction survey revealed high rating of the overall service (90.6/100). None of the patients felt that they lacked education on their disease or medication. Only 6% of the respondents gave negative feedback, reasons including feeling overwhelmed with information or not being given a cause for their symptoms. The multi-disciplinary approach was highly valued and only 3% would rather see a doctor and nurse on separate days. CONCLUSION: The specific clinic model provides an ideal setting for a one-stop service, avoiding unnecessary visits, collecting patient data, and enhancing the patient experience and journey through the system. Where possible, the specific clinic model could be used or adapted to build similar models in other rheumatology departments. The clinic model could also form the basis for services in other specialties dealing with chronic conditions.
