ABSTRACT
INTRODUCTION:
Availability of anti-viral agents and need to isolate infected patients increases the need to confirm the diagnosis of influenza before determining patient disposition.OBJECTIVES:
We sought to determine if time-to-disposition (TTD) was shorter among patients tested for influenza using an Emergency Department (ED) Point-of-care (POC) test compared to core laboratory (lab) test and to determine difference in antibiotic use between groups.METHODS:
We prospectively enrolled a convenience sample of ED patients for whom influenza testing was ordered during influenza season 2017. Participants were randomized to POC or lab. Data collected included demographics, chief complaint, influenza test results, turnaround time (TAT), whether antibiotics were given, and TTD. Descriptive statistics were calculated and group comparisons conducted using chi squared and Wilcoxon Rank Sum tests.RESULTS:
Study population included 100 in the POC group and 97 in the lab group. Demographics were similar between POC and lab participants. More flu positive results were reported in the POC group compared to the lab group (51.0% vs. 33.0% pâ¯=â¯0.01). The median TTD was 146.5â¯min (IQR 98.5) for POC group and 165.5â¯min (IQR 127) for lab group (pâ¯=â¯0.26). The median TAT was 30.5â¯min (IQR 7.5) for POC group and 106.0â¯min (IQR 55) for core lab group (pâ¯=â¯0.001). Antibiotics were given to 14.0% of POC participants and 14.4% of lab participants (pâ¯=â¯0.93).CONCLUSIONS:
Although use of a POC influenza test provided more rapid TAT than use of a core lab test, there was no significant difference in TTD or antibiotic use between groups.Palavras-chave
