IntroductionTo provide an epidemiological description of radial head subluxation, also known as nursemaid’s elbow, from a database of emergency department visits.MethodsWe conducted a retrospective medical record review of patients 6 years of age and younger, who presented to the ED between January 1, 2005, and December 31, 2012, and were diagnosed with nursemaid’s elbow. Inclusion criteria consisted of chart information, including date, unique account number, medical record number, weight, age, sex, and arm affected. Exclusion criteria included any charts with missing or incomplete data.ResultsThere were 1,228 charts that met inclusion criteria. The majority of patients were female (60%). The mean age was 28.6 months (±12.6). The left arm was affected 60% of the time. Most of the included patients were over the 75th percentile for weight and more than one quarter were over the 95th percentile in each gender.ConclusionThe average age of children presenting with nursemaid’s elbow was 28.6 months. Females were affected more than males, and the left arm was predominately affected. Most patients were above the 75th percentile for weight and more than one quarter were over the 95th percentile for weight.
Introduction: Eligible residents during their fourth postgraduate year (PGY-4) of emergency medicine (EM) residency training who seek specialty board certification in emergency medicine may take the American Osteopathic Board of Emergency Medicine (AOBEM) Part 1 Board Certifying Examination (AOBEM Part 1). All residents enrolled in an osteopathic EM residency training program are required to take the EM Resident In-service Examination (RISE) annually. Our aim was to correlate resident performance on the RISE with performance on the AOBEM Part 1. The study group consisted of osteopathic EM residents in their PGY-4 year of training who took both examinations during that same year.Methods: We examined data from 2009 to 2012 from the National Board of Osteopathic Medical Examiners (NBOME). The NBOME grades and performs statistical analyses on both the RISE and the AOBEM Part 1. We used the RISE exam scores, as reported by percentile rank, and compared them to both the score on the AOBEM Part 1 and the dichotomous outcome of passing or failing. A receiver operating characteristic (ROC) curve was generated to depict the relationship.Results: We studied a total of 409 residents over the 4-year period. The RISE percentile score correlated strongly with the AOBEM Part 1 score for residents who took both exams in the same year (r=0.61, 95% confidence interval [CI] 0.54 to 0.66). Pass percentage on the AOBEM Part 1 increased by resident percent decile on the RISE from 0% in the bottom decile to 100% in the top decile. ROC analysis also showed that the best cutoff for determining pass or fail on the AOBEM Part 1 was a 65th percentile score on the RISE.Conclusion: We have shown there is a strong correlation between a resident's percentile score on the RISE during their PGY-4 year of residency training and first-time success on the AOBEM Part 1 taken during the same year. This information may be useful for osteopathic EM residents as an indicator as to how well prepared they are for the AOBEM Part 1 Board Certifying Examination.
Objective. To determine the accuracy of Point-Of-Care testing (PoCT) creatinine values when compared to standard central laboratory testing (IDMS) and to demonstrate if and how a discrepancy could lead to improper risk stratification for contrast induced nephropathy (CIN). Methods. We conducted a descriptive retrospective chart review of patients seen in the Emergency Department of a single suburban, community, and academic medical center. We included patients who presented to the department between March 2013 and September 2014 who had blood samples analyzed by both PoCT and IDMS. Results. Mean IDMS creatinine values were 0.23 mg/dL higher when compared with i-Stat values. 95% of the time, the IDMS creatinine value was variable and ranged from −0.45 mg/dL to +0.91 mg/dL when compared to the i-Stat creatinine. When using i-Stat creatinine values to calculate GFR, 47 out of 156 patients had risk category variations compared to using the IDMS value. This affected 30.1% of the total eligible sample population (22.9% to 37.3% with 95% CI). Conclusion. We found a significant discrepancy between PoCT and IDMS creatinine values and found that this discrepancy could lead to improper risk stratification for CIN.
