Randomized Controlled Trial
Success of ultrasound-guided versus landmark-guided arthrocentesis of hip, ankle, and wrist in a cadaver model.
The objectives of this study were to evaluate emergency medicine resident-performed ultrasound for diagnosis of effusions, compare the success of a landmark-guided (LM) approach with an ultrasound-guided (US) technique for hip, ankle and wrist arthrocentesis, and compare change in provider confidence with LM and US arthrocentesis. ⋯ EM residents were able to successfully identify joint effusions with ultrasound, however we were unable to detect significant differences in actual procedural success between the two modalities. Further studies are needed to define the role of ultrasound for arthrocentesis in the emergency department.

Current Infectious Disease Society of America (IDSA) guidelines for the management of purulent skin or soft tissue infections do not account for patient age in treatment recommendations. The study objective was to determine if age was associated with outpatient treatment failure for purulent skin infection after adjusting for IDSA treatment guidelines. ⋯ Elderly patients with purulent skin infections, whose providers followed the 2014 IDSA guidelines, were more likely to fail initial treatment than younger patients. This study suggests that there is a need to re-evaluate treatment guidelines in elderly patients.

Nearly 30% of patients who present to an ED with acute, new onset, low back pain (LBP) report LBP-related functional impairment three months later. These patients are at risk of chronic LBP, a highly debilitating condition. It has been reported previously that functional impairment, depression, and psychosomatic symptomatology at the index visit are associated with poor LBP outcomes. We wished to replicate those findings in a cohort of ED patients, and also to determine if clinical features present at one week follow-up could predict three-month outcomes in individual patients. ⋯ In spite of a strong association at the group level between presence of LBP at one week and functional impairment at three months, when used to predict outcomes in individual patients, presence of pain failed to discriminate with clinically meaningful utility between acute LBP patients destined to have a favorable versus unfavorable three-month outcome.
