Abstract

Patients in need of urgent inpatient treatment were recruited prospectively. A rapid point of care polymerase chain reaction test (POC-PCR; Liat®) for SARS-CoV2 was conducted in the Emergency Department (ED) and a second PCR-test from the same swab was ordered in the central laboratory (PCR). POC-PCR analyzers were digitally integrated in the laboratory information system. Overall, 160 ED patients were included. A valid POC-PCR-test result was available in 96.3% (n = 154) of patients. N = 16 patients tested positive for Severe Acute Respiratory Syndrome-Corona Virus 2 (10.0%). The POC PCR test results were available within 102 minutes (median, interquartile range: 56-211), which was significantly earlier compared to the central laboratory PCR (811 minutes; interquartile range: 533-1289, P < 0.001). The diagnostic accuracy of the POC-PCR test was 100%. The implementation and digital laboratory information system integration was successfully done. Staff satisfaction with the POC process was high. The POC-PCR testing in the ED is feasible and shows a very high diagnostic performance. Trial registration: DRKS00019207.
