Methods: We performed a retrospective lab review of Biofire Filmarray GIP results from WBAMC dating from November 2016 to May 2017. Descriptive data analysis was applied involving proportions (percentages), means, and other summary statistics.
Results: Population studied was predominantly male (69.5%). Thirty eight percent and 28% of the total population were aged from 19 to 50 and 51 to 71 years old, respectively. One hundred ninety-seven total tests were evaluated over this time period, with a 45.2% positive rate. The 5 most identified pathogens were Clostridium difficile (29% of all positive tests), Enteropathogenic Escherichia coli (EPEC) (14.6%), Norovirus (25.8%), Sapovirus (15.7%), and Rotavirus (12.3%). Positive tests for C. difficile, Norovirus, and EPEC were stable through the time period analyzed. Sapovirus positive results decreased during this time period, while Rotavirus increased towards the spring/summer season. No Escherichia coli O157, Enteroinvasive E. coli (EIEC), Enterotoxigenic E. coli (ETEC), Plesiomonas/Shigella, Vibrio or Yersinia species were identified.
Conclusion: Positive results for Norovirus and Rotavirus followed trends nationally reported to the Centers for Disease Control (CDC). Trends for Sapovirus and EPEC correlate with previously reported increases during the spring/summer time period. Clostridium identifications remained stable likely due to association with hospitalization and antibiotic use. Continued surveillance is needed, particularly with bacterial species, given their propensity for significant morbidity and mortality.
