RESUMEN
During the first wave of Covid-19 in France, in spring 2020, healthcare institution's laboratory had to adapt itself quickly to the growing demand for emergency biology, in particular by reorganizing their POCT analyzers: redeployment of analyzers and/or new installations. In order to analyze this management, a subgroup of 15 hospital biologists from the SFBC Working Group "Biochemical markers of Covid-19" sent, in fall 2020, an on-line survey to French hospital laboratories using POCT. Answers analysis (n = 86) shows a territorial disparity related to the severity of the first wave: increased activity essentially in red zones, management of unexpected situations, training of additional nursing staff for 40 % of the laboratories... The survey also showed simplification of aspects related to accreditation those periods of health crisis. An additional survey, carried out in the spring of 2021, showed good overall satisfaction of the healthcare services (n = 139) concerning the services provided by biology in the POCT sector. Because of their great adaptation capacity, the laboratories and their POCT-teams have played a key role in the management of the first wave of Covid-19 in France. However, the success of these organizations requires an essential collaboration between laboratories and healthcare services. The results of this survey are fundamental in the context of the prolongation of the pandemia throughout the world with a POCT sector appearing to be growing.

OBJECTIVES: Crowding is a frequent concern in the emergency department (ED). Laboratory point-of-care testing (POCT) has been proposed to decrease patients' length of stay (LOS). Our objective was to determine whether an extended panel of POCT solutions could reduce LOS. METHODS: This was a single-center, prospective, open-label, controlled cluster-randomized study. Blood test processing was randomized into 1-week inclusion periods: interventional arm (laboratory analyses performed on POCT analyzers implemented in the ED) or control arm (central laboratory). The primary endpoint was LOS of patients in the ED. Secondary endpoints were time to result (TTR), ED crowding surrogates, and average total cost of an ED visit in each arm. RESULTS: A total of 23,231 patients were included and 20,923 were analyzed for the main outcome measure. Mean ± SD age was 46 ± 20 years, and 7,905 (36%) underwent blood sampling. Mean ± SD LOSs were 203 ± 161 and 210 ± 168 minutes in the POCT and control arms, respectively. LOS reduction for the entire ED population was -9 minutes (95% confidence interval [CI] = -22 to 5, p = 0.22) compared to the control arm and -17 minutes (95% CI = -34.0 to 0.6, p = 0.06) for patients undergoing blood sampling. The mean ± SD TTRs were 28 ± 31 and 79 ± 34 minutes in the POCT and control arms, respectively (TTR reduction = -51 minutes, 95% CI = -54 to -48 minutes, p < 0.001). CONCLUSIONS: The implementation of an extended panel of POCT solutions in an ED did not significantly reduce the LOS, but reduced the TTR.
