Clinical Trial Summary

This is a prospective, observational study of patients presenting to the emergency departments at 9 EMERGEncy ID NET sites. The objectives of the proposed study are to: 1. Describe the range and proportion of infectious agents in synovial fluid as detected by standard C&S and investigational PCR testing, i.e., Biofire® Film Array® Bone and Joint Infection (BJI) Panel, 2. Describe the epidemiology of patients receiving diagnostic arthrocentesis and those diagnosed with septic arthritis in the emergency department (ED), 3. Determine the prevalence of septic arthritis in US ED patients presenting with an atraumatic painful swollen joint, and 4. Determine the clinical (history and physical examination) and laboratory characteristics of septic arthritis. Study coordinators screen the ED log for adult patients presenting with joint pain and whose treating physician ordered an arthrocentesis. After confirming eligibility, study coordinators approach the patient to explain the study, and present the written consent form. If the patient agrees to participate and consent, the study coordinator completes an enrollment data collection using patient and treating physician interview to gather responses. After enrollment, the study coordinator will ensure that approximately 0.3-1.0 mL of leftover synovial fluid is saved and stored in a freezer for shipment to a central laboratory (Truman Medical Center hospital laboratory, Kansas City, MO) for testing. Approximately 30 days after enrollment, study coordinators complete an electronic medical record (EMR) review.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Prevalence of pathogens	We will describe the prevalence of pathogens identified using PCR testing	Two years
Primary	Prevalence of septic arthritis	We will describe the prevalence of septic arthritis among patients who have joint taps in emergency departments	Two years
Secondary	Clinical characteristics of septic arthritis	We will compare clinical characteristics, such as duration of symptoms, medical history, immunocompromising conditions, vitals, and demographics between those who have septic arthritis vs. those who do not to determine if there are possible predictors	Two years
Secondary	Laboratory characteristics of septic arthritis	We will compare laboratory characteristics, such as white blood cell count, presence of crystals, gram stain, and culture results between those who have septic arthritis vs. those who do not to determine if there are possible predictors	Two years
