Identification of gender differences in ultrasound milestone assessments during emergency medicine residency training: a pilot studyObjectives: Prior literature suggests that incongruities between male and female resident's procedural competency may be explained by gender bias during the evaluation process. There are no known studies investigating gender differences in the assessment of ultrasound-based procedural skills among emergency medicine (EM) residents. The purpose of this study was to evaluate for gender differences in ultrasound milestone assessments among EM residents. Methods: This is a retrospective study including EM residents. Milestone assessment data were collected from a total of 3 Accreditation Council for Graduate Medical Education (ACGME) EM residency programs representing a 3-year period The outcome measures included mean milestone levels, milestone levels at baseline and graduation and differences in milestone achievement between female and male EM residents. An unpaired Student's t-test was used to compare milestone scores between female and male residents. Results: A total of 456 ultrasound milestone evaluations were collected from 91 EM residents (34 females [37%] and 57 males [63%]). No significant differences were noted in the overall mean milestone level between females (2.3 +/- 0.6) and males (2.2 +/- 0.6) (P=0.387). There were no significant differences noted in the ultrasound milestone level between females (0.8 +/- 0.6) and males (0.7 +/- 0.7) at baseline (P=0.754). Although it did not reach statistical significance (P=0.197), the increase in the mean ultrasound milestone level from baseline to graduation was greater in males (3.4 +/- 0.7) compared to females (3.1 +/- 0.7). Conclusion: Overall, there were no statistically significant differences in the mean ultrasound milestone levels between females and males. The rate of ultrasound milestone level achievement during EM residency training at our institution had a slight tendency to be higher for males than females in the observed residency programs; however, this also did not reach statistical significance. Possible gender bias while evaluating ultrasound milestone levels needs to be further studied on a larger scale.
NASHA hyaluronic acid for the treatment of shoulder osteoarthritis: a prospective, single-arm clinical trialBackground: Osteoarthritis of the shoulder or glenohumeral joint is a painful condition that can be debilitating. Intra-articular injection with hyaluronic acid should be considered for patients not responding adequately to physical therapy or anti-inflammatory medication. Methods: This was a single-arm, open-label, prospective study of a single intra-articular injection of NASHA (non-animal hyaluronic acid) in patients with symptomatic glenohumeral osteoarthritis. Patients were followed up for 26 weeks post-treatment, during which time rescue medication with acetaminophen was permissible. The study objective was to demonstrate that a single injection of NASHA is well tolerated with an over-6-month 25% reduction in shoulder pain on movement, assessed using a 100-mm visual analog scale. Results: Forty-one patients were enrolled, all of whom received study treatment. The mean decrease in shoulder pain on movement score over the 6-month study period was -20.1 mm (95% CI: -25.2, -15.0 mm), corresponding to a mean reduction of 29.5% (22.0, 37.0%). Statistically significant improvements were also observed in shoulder pain at night and patient global assessment. There was no clear change over time in the percentage of patients using rescue medication and mean weekly doses were below 3500 mg. Seventeen patients (41.5%) experienced adverse events, all of which were mild or moderate. Two adverse events (both shoulder pain) were deemed related to study treatment. Conclusion: This study provides preliminary evidence that a single injection of NASHA may be efficacious over 6 months and well tolerated in patients with symptomatic glenohumeral osteoarthritis. Larger studies are needed for confirmation.
