Point-of-Care Ultrasound for the Detection of Hip Effusion and Septic Arthritis in Adult Patients With Hip Pain and Negative Initial Imaging.

BACKGROUND: Acute or recurrent hip pain in adults can be a challenging presentation in the emergency department. While ultrasound is routinely used in the evaluation of pediatric patients with hip pain and a new limp, it is not commonly used for this purpose in adult emergency medicine. This case series demonstrates the clinical utility of point-of-care ultrasound (POCUS) in adult patients with acute or recurrent hip pain because performance of POCUS was the critical action that led to the identification of pathologic hip effusions in this series of adults. CASE SERIES: This case series includes 5 patients in whom clinical suspicion existed for the presence of a hip effusion and possible septic arthritis, despite nondiagnostic radiographic findings. Ultrasound was used to detect the effusion and guide subsequent arthrocentesis, imaging, or surgical intervention. In all patients, computed tomography scans or magnetic resonance imaging scans were later used to confirm the presence of effusion. In all 5 patients (2 women and 3 men, with a mean age of 47.4 years), POCUS accurately detected the presence of hip effusion. Two of 5 synovial collections were caused by septic arthritis as confirmed by synovial fluid microbiologic examination. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case series emphasizes the clinical utility of POCUS in adult patients with acute and recurrent hip pain to detect a hip effusion, particularly in patients with significant risk factors for septic arthritis. POCUS can also be used to guide further imaging, arthrocentesis, surgical consultation, and intervention.

Internet Websites for Chest Pain Symptoms Demonstrate Highly Variable Content and Quality.

OBJECTIVE: Chest pain is a common symptom with causes that range from benign to serious. We assess the content and quality of websites about chest pain symptoms that describe its causes and when to seek care. METHODS: We used five search engines (Google, Bing, Yahoo, Ask, AOL) using the term "chest pain" and assessed the first 30 websites that resulted from each search. We excluded websites that were diagnosis-driven, intended for physicians, patient blogs, advertisements, news, or videos. For included websites, we assessed for the presence of content potentially useful to patients with chest pain symptoms; website quality with three instruments (DISCERN, HONcode, and JAMA benchmark criteria); readability using four validated scores, accessibility, usability, and reliability using the LIDA instrument; and popularity using the Alexa tool. RESULTS: In 27 included websites, 96 and 81% mentioned cardiac and noncardiac causes of chest pain, respectively, while 85% described when to seek emergency care. Only 51% of websites mentioned potential tests that might be used to diagnose symptoms, 22% described potential treatments, and 11% mentioned consequences if treatment is delayed or avoided. The median website DISCERN score was 23 (interquartile range [IQR] = 18-32) out of a possible 45 points, which can be interpreted as low to medium quality. A total of 44% of websites had HONcode certification, and only 11% fulfilled all four JAMA benchmark criteria. Average reading scores demonstrated that half of websites were above the eighth to ninth grade reading level. With LIDA, the average scores were "medium" for accessibility at 83% and usability at 59% and "low" for reliability at 43%. CONCLUSIONS: Many websites that provide health information for patients about chest pain symptoms are not reliable. There is highly variable content and quality, and the average website is difficult to read for patients with low health literacy.
