Conclusions-Septic arthritis continues to be associated with a considerable degree of morbidity and mortality. These results confirm the importance of obtaining synovial fluid and blood for culture before starting antimicrobial treatment. The apparent poorer outcome found with surgical intervention is in line with some previous suggestions but should be interpreted with caution in light of the retrospective nature of this study.

The Meningitis/Encephalitis Panel (MEP) is a sensitive and specific Food and Drug Administration–approved molecular diagnostic test for the 14 most common infectious etiologies of meningoencephalitis. Using a before–after controlled study design, MEP reduced length of hospital stay by 1.5 days, and this effect was mediated by the reduced time to final microbiology reporting.

Background: Molecular syndromic panels can rapidly detect common pathogens responsible for acute gastroenteritis in hospitalized patients. Their impact on both patient and healthcare system outcomes is uncertain compared to conventional stool testing. This randomized trial evaluates the impact of molecular testing on in-hospital resource utilization compared to conventional stool testing.Methods: Hospitalized patients with acute diarrheal illness were randomized 1:1 to either conventional or molecular stool testing with the BioFire FilmArray gastrointestinal panel (FGP). The primary outcome was the duration of contact isolation, and secondary outcomes included other in-hospital resource utilization such as diagnostic imaging and antimicrobial use.Results: A total of 156 patients were randomized. Randomization resulted in a balanced allocation of patients across all three age strata (<18, 18-69, ≥70 years old). The proportion of positive stools was 20.5% vs 29.5% in the control and FGP groups, respectively (p=0.196). The median duration of contact isolation was 51 hours (interquartile range [iqr] 66) and 69 hours (iqr 81) in the conventional and FGP groups, respectively (p=0.0513). There were no significant differences in other in-hospital resource utilization between groups.Conclusions: There were no differences in in-hospital resource utilization observed between the FGP and conventional stool testing groups.
