Training Background and Demographic Characteristics of Primary Care Team Physicians in Professional Sports.

Background: Previous studies have shown that most professional head and orthopaedic team physicians are men, and most orthopaedic team physicians are fellowship-trained. It is unknown whether this holds true for primary care team physicians. Purpose: To evaluate the residency and fellowship training background as well as the demographic characteristics of primary care team physicians in professional sports. Study Design: Cross-sectional study. Methods: Publicly available information was used to determine the lead and supporting primary care team physicians for every US-based team in Major League Baseball, Major League Soccer, National Basketball Association, National Football League, National Hockey League, National Women's Soccer League, and Women's National Basketball Association. Data regarding training background and sex were obtained using internet-based sources. Results: We identified 310 primary care team physicians from all 165 US-based teams in the 7 leagues included in the study. Female physicians comprised 11.5% (19/165) of the lead primary care team physicians and 14.2% (44/310) of all primary care team physicians. Overall, 66.7% (110/165) of lead primary care team physicians and 75.5% (234/310) of all primary care team physicians were sports medicine fellowship-trained. There was a higher proportion of female (37.5%) and fellowship-trained (93.8%) physicians in women's professional sports leagues. Most primary care team physicians (244/310 [78.7%]) were trained in family medicine or internal medicine. Conclusion: Women constituted a small minority of primary care team physicians in professional sports. Most primary care team physicians were residency trained in family medicine or internal medicine and were sports medicine fellowship-trained. The proportion of female and fellowship-trained primary care team physicians was highest in the National Women's Soccer League and the Women's National Basketball Association.

Emergency Facial Injuries in Athletics.

Dental and oral injuries are a common occurrence in sport. Initial evaluation should always begin with an assessment of the patient's airway, breathing, circulation, as well as identification of associated injuries. Tooth avulsions are the only true dental emergency. Oral lacerations frequently do not require repair; however, special attention should be paid to lip lacerations involving the vermillion border. Most tooth and oral lacerations can be treated on the field with urgent referral to a dentist.

American Medical Society of Sports Medicine Position Statement: Mononucleosis and Athletic Participation.

ABSTRACT: Infectious mononucleosis (IM) is a common illness in children and young adults caused primarily by the Epstein-Barr Virus (EBV). Transmission occurs primarily through sharing oral secretions, thus IM is known as the "kissing disease." Common clinical manifestations include fever, pharyngitis, posterior cervical lymphadenopathy, and splenomegaly. Atypical lymphocytosis and transaminase elevations are common, and the diagnosis of IM is confirmed with laboratory findings of a positive heterophile antibody ("Monospot"), polymerase chain reaction, or antibodies specific to EBV. Individuals with acute IM may be quite symptomatic and not feel well enough to participate in sports. Splenic enlargement is common, with rupture a relatively rare occurrence, typically occurring within a month of symptom onset, but this risk complicates sports participation, and is often the reason for restricting activity. The management of IM is primarily supportive, with no role for antivirals or corticosteroids. The variability of clinical presentation and the risk of splenic rupture in patients with IM present clinicians with challenging return to play/return to sport (RTS) decisions. This position statement updates the Evidence-Based Subject Review on Mononucleosis by the American Medical Society for Sports Medicine published in 2008 and reviews the epidemiology, clinical manifestations, laboratory assessment, and management including RTS for the athlete with IM. This statement also addresses complications, imaging, special considerations, diversity and equity considerations, and areas for future clinical research. Understanding the evidence regarding IM and sport is essential when communicating with athletes and their families and incorporating shared decision-making in the RTS decision.

Patients Who Return to Sport After Primary Anterior Cruciate Ligament Reconstruction Have Significantly Higher Psychological Readiness: A Systematic Review and Meta-analysis of 3744 Patients.

BACKGROUND: Although objective outcomes assessing knee function are essential measurements for return to sport, psychological factors have become increasingly recognized as equally important parameters for determining an athlete's ability to return to sport after surgery. PURPOSE: To systematically review the literature to determine whether patients who returned to sport after anterior cruciate ligament (ACL) reconstruction had improved psychological scores (as measured with validated questionnaires) compared with patients who did not return to sport. STUDY DESIGN: Systematic review and meta-analysis; Level of evidence, 3. METHODS: A systematic review was performed using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and was preregistered on PROSPERO. Four databases were searched for level 1 to 3 studies that compared at least 1 psychological outcome measured by a validated questionnaire for patients who did and did not return to sport after primary ACL reconstruction. The following data were recorded: study and patient characteristics; psychological metrics (ACL-Return to Sport Injury [ACL-RSI] scale, Knee Self-Efficacy Scale [K-SES], and Tampa Scale of Kinesiophobia [TSK/TSK-11]); International Knee Documentation Committee (IKDC) score; and clinical metrics. Study methodological quality was analyzed using the methodological index for non-randomized studies (MINORS), and the mean difference (MD) and 95% CI were calculated for each psychological outcome score using the inverse variance method. RESULTS: We included and analyzed 16 articles (3744 patients; 38.9% female; mean age range, 17-28.7 years; mean MINORS score, 19.9 ± 1.4). Overall, 61.8% of athletes returned to sport (66.8% of male patients; 55.4% of female patients). Patients who returned scored significantly higher on the ACL-RSI scale (MD, 20.8; 95% CI, 15.9 to 25.7; P < .001), significantly higher on the K-SES (MD, 1.3; 95% CI, 0.2 to 2.3; P = .036), and significantly lower on the TSK/TSK-11 (MD, 10.1%; 95% CI, -12.1% to -8.2%; P = .004). Those returning to sport did not exceed the minimal clinically important difference for IKDC score versus those not returning to sport. CONCLUSION: Patients who returned to sport after primary ACL reconstruction had significantly higher psychological readiness, higher self-efficacy, and lower kinesiophobia compared with those who did not return to sport, despite having clinically similar knee function scores. Evaluation of psychological readiness, in combination with other objective measurements, is a critical component of return-to-sport evaluation in athletes after primary ACL reconstruction.

Prevalence of Positive Rapid Antigen Tests After 7-Day Isolation Following SARS-CoV-2 Infection in College Athletes During Omicron Variant Predominance.

Importance: The US Centers for Disease Control and Prevention shortened the recommended isolation period for SARS-CoV-2 infection from 10 days to 5 days in December 2021. It is unknown whether an individual with the infection may still have a positive result to a rapid antigen test and potentially be contagious at the end of this shortened isolation period. Objective: To estimate the proportion of individuals with SARS-CoV-2 infection whose rapid antigen test is still positive starting 7 days postdiagnosis. Design, Setting, and Participants: This case series analyzed student athletes at a National Collegiate Athletic Association Division I university campus who tested positive for SARS-CoV-2 between January 3 and May 6, 2022. Individuals underwent rapid antigen testing starting 7 days postdiagnosis to determine whether they could end their isolation period. Exposures: Rapid antigen testing 7 days after testing positive for SARS-CoV-2. Main Outcomes and Measures: Rapid antigen test results, symptom status, and SARS-CoV-2 variant identification via campus wastewater analysis. Results: A total of 264 student athletes (140 [53%] female; mean [SD] age, 20.1 [1.2] years; range, 18-25 years) representing 268 infections (177 [66%] symptomatic, 91 [34%] asymptomatic) were included in the study. Of the 248 infections in individuals who did a day 7 test, 67 (27%; 95% CI, 21%-33%) tests were still positive. Patients with symptomatic infections were significantly more likely to test positive on day 7 vs those who were asymptomatic (35%; 95% CI, 28%-43% vs 11%; 95% CI, 5%-18%; P < .001). Patients with the BA.2 variant were also significantly more likely to test positive on day 7 compared with those with the BA.1 variant (40%; 95% CI, 29%-51% vs 21%; 95% CI, 15%-27%; P = .007). Conclusions and Relevance: In this case series, rapid antigen tests remained positive in 27% of the individuals after 7 days of isolation, suggesting that the Centers for Disease Control and Prevention-recommended 5-day isolation period may be insufficient in preventing ongoing spread of disease. Further studies are needed to determine whether these findings are present in a more heterogeneous population and in subsequent variants.

Premature ventricular contractions (PVCs) in young athletes.

There is a growing body of literature focusing on the morphology, management, and outcomes of PVCs in athletes. This review summarizes this literature and establishes recommendations on management, treatment, and indications for specialist referral in this patient population. The sports medicine physician's responses and recommendation should be made in conjunction with the athletes wishes. Medications or ablations are not always necessary in all athletes if they are followed with regular evaluations.

Use of Monospot Testing in the Diagnosis of Infectious Mononucleosis in the Collegiate Student-Athlete Population.

OBJECTIVE: To determine the utility of monospot testing in the diagnosis of mononucleosis in the collegiate student-athlete clinical setting. DESIGN: Retrospective cohort study. SETTING: National Collegiate Athletic Association Division I sports medicine clinic. PATIENTS: All varsity student athletes who had a monospot test and Epstein-Barr virus (EBV) titers obtained from January 1, 2016, through March 31, 2020, (n = 199) were included. INDEPENDENT VARIABLES: Monospot, EBV antibody titers, and liver transaminase results. MAIN OUTCOME MEASURES: Using EBV titers indicating acute or recent infection as the gold standard for diagnosing infectious mononucleosis (IM), the reliability of a positive monospot test and elevated liver transaminases for the diagnosis of IM were examined. RESULTS: The monospot test had a sensitivity and specificity of 80.0% and 90.6%, respectively, with a positive predictive value of 36.4% and a negative predictive value of 98.5% in this cohort. All athletes diagnosed with IM also had elevated liver transaminases. CONCLUSIONS: The specificity of the monospot test is lower than previously reported in the literature, and a positive test is not sufficient to diagnose mononucleosis in this clinical setting. Positive monospot results should be confirmed with EBV antibody testing. Elevated transaminase levels are highly correlated with acute IM and could play a supporting role in the diagnosis.

Critical Care Clinicians' Experiences of Patient Safety During the COVID-19 Pandemic.

OBJECTIVE: It is unknown how hospital- and systems-level factors have impacted patient safety in the intensive care unit (ICU) during the COVID-19 pandemic. We sought to understand how the pandemic has exacerbated preexisting patient safety issues and created novel patient safety challenges in ICUs in the United States. METHODS: We performed a national, multi-institutional, mixed-methods survey of critical care clinicians to elicit experiences related to patient safety during the pandemic. The survey was disseminated via email through the Society of Critical Care Medicine listserv. Data were reported as valid percentages, compared by COVID caseload and peak of the pandemic; free-text responses were analyzed and coded for themes. RESULTS: We received 335 survey responses. On general patient safety, 61% felt that conditions were more hazardous when compared with the prepandemic period. Those who took care of mostly COVID-19 patients were more likely to perceive that care was more hazardous (odds ratio, 4.89; 95% CI, 2.49-9.59) compared with those who took care of mostly non-COVID-19 or no COVID-19 patients. In free-text responses, providers identified patient safety risks related to pandemic adaptations, such as ventilator-related lung injury, medication and diagnostic errors, oversedation, oxygen device removal, and falls. CONCLUSIONS: Increased COVID-19 case burden was significantly associated with perceptions of a less safe patient care environment by frontline ICU clinicians. Results of the qualitative analysis identified specific patient safety hazards in ICUs across the United States as downstream consequences of hospital and provider strain during periods of the COVID-19 pandemic.

Increased Risk of ACL Injury for Female but Not Male Soccer Players on Artificial Turf Versus Natural Grass: A Systematic Review and Meta-Analysis.

Background: Both natural grass (NG) and artificial turf (AT) are popular playing surfaces for soccer. Biomechanical studies have found increased frictional forces on AT that may lead to anterior cruciate ligament (ACL) injury. The increased risk of ACL injury during soccer in female participants may amplify this effect. Purpose: To systematically review the literature for studies comparing ACL injury risk in soccer players on AT versus NG and to specifically determine whether there were differences in injury risk in male versus female players when considering the playing surface. Study Design: Systematic review; Level of evidence, 3. Methods: A systematic review was performed using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Three databases were searched for studies with evidence level 1 to 3 that compared the incidence of ACL injuries on AT versus NG in soccer players. Data recorded included study characteristics, sex, competition level, exposure setting (games or practices), turf type, and ACL injury information. Study methodological quality was analyzed using the methodological index for non-randomized studies (MINORS) score, and incidence rate ratios (IRRs) were calculated. Results: Included were 7 articles (3 studying professional soccer, 3 collegiate soccer, 1 youth-level soccer; 4 male cohorts, 2 female cohorts, and 1 male and female cohort; mean MINORS score, 20 ± 0.8). Pooled ACL injury IRRs demonstrated no significant differences in overall ACL injury risk when playing soccer on AT compared with NG (IRR = 0.57 [95% CI, 0.21-1.53]; P = .31). A significantly increased risk of ACL injury in games played on AT compared with NG was detected for female (IRR = 1.18 [95% CI, 1.05-1.31]; P = .004) but not for male players (IRR = 1.18 [95% CI, 0.97-1.42]; P = .09). Subgroup analyses showed no significant differences in injury risk for games (IRR = 1.07 [95% CI, 0.97-1.18]; P = .20) or practices (IRR = 0.21 [95% CI, 0.04-1.23]; P = .09). Conclusion: Findings indicated that female soccer players had a significantly higher risk of ACL injury when playing games on AT versus NG, whereas no significant difference was seen in male players. No differences were found for the combined male/female cohort or for soccer games or training sessions played on AT compared with NG.

Factors Associated With a Prolonged Time to Return to Play After a Concussion.

BACKGROUND: Prognosticating recovery times for individual athletes with a concussion remains a challenge for health care providers. Several preinjury and postinjury factors have been proposed to be predictive of prolonged return-to-play (RTP) times, but the data in this area are still sparse. PURPOSES: This study aimed to identify risk factors associated with prolonged recovery times and determine which are most predictive of prolonged recovery times in a head-to-head comparison. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: All concussions occurring between September 2017 and August 2020 at a single National Collegiate Athletic Association Division I institution were reviewed and included in this study. Preinjury modifiers including age, sex, sport, concussion history, and past medical problems were collected from the electronic medical records. Postinjury modifiers analyzed included initial and follow-up Sport Concussion Assessment Tool 5th Edition scores, vestibular evaluation findings, and eye tracking results. RESULTS: A total of 159 athletes and 187 concussion cases were included. Preinjury factors that were correlated with prolonged RTP times included a history of concussions (P = .015), a history of migraines (P = .013), and whether an athlete participated in an individual sport (P = .009). Postinjury factors correlated with prolonged RTP times included the total number (P = .020) and severity (P = .023) of symptoms as well as abnormal Vestibular Ocular Motor Screening findings (P = .002). Overall, 6 different symptoms (balance problems, difficulty concentrating, light sensitivity, drowsiness, fatigue/low energy, and difficulty remembering) were significantly correlated with prolonged RTP times. The study also found that the number and severity of symptoms were additive in a dose-dependent fashion. On multivariable analysis of all these factors, a history of concussions was found to be the most predictive of prolonged RTP times, while participation in an individual sport had the largest effect on recovery times. CONCLUSION: Several preinjury and postinjury risk factors were identified as being correlated with prolonged recovery times. Many of these risk factors were also found to be additive in nature. This information provides clinicians with a valuable tool in prognosticating and estimating recovery times for athletes. The study also revealed that athletes participating in individual sports had longer RTP times compared with athletes in team sports, which is a novel finding that requires further research.

Comparison of SARS-CoV-2 Test Positivity in NCAA Division I Student Athletes vs Nonathletes at 12 Institutions.

Importance: The COVID-19 pandemic initially led to the abrupt shutdown of collegiate athletics until guidelines were established for a safe return to play for student athletes. Currently, no literature exists that examines the difference in SARS-CoV-2 test positivity between student athletes and nonathletes at universities across the country. Objective: To identify the difference in risk of COVID-19 infection between student athlete and nonathlete student populations and evaluate the hypothesis that student athletes may display increased SARS-CoV-2 test positivity associated with increased travel, competition, and testing compared with nonathletes at their respective universities. Design, Setting, and Participants: In this cross-sectional analysis, a search of publicly available official university COVID-19 dashboards and press releases was performed for all 65 Power 5 National Collegiate Athletic Association (NCAA) Division I institutions during the 2020 to 2021 academic year. Data were analyzed at the conclusion of the academic year. Schools that released at least 4 months of testing data, including the fall 2020 football season, for student athletes and nonathlete students were included in the analysis. Power 5 NCAA Division I student athletes and their nonathlete student counterparts were included in the analysis. Exposure: Designation as a varsity student athlete. Main Outcomes and Measures: The main outcome was SARS-CoV-2 test positivity for student athletes and nonathlete students at the included institutions for the 2020 to 2021 academic year, measured as a relative risk for student athletes. Results: Among 12 schools with sufficient data available included in the final analysis, 555 372 student athlete tests and 3 482 845 nonathlete student tests were performed. There were 9 schools with decreased test positivity in student athletes compared with nonathlete students (University of Arkansas: 0.01% vs 3.52%; University of Minnesota: 0.63% vs 5.96%; Penn State University: 0.74% vs 6.58%; Clemson University: 0.40% vs 1.88%; University of Louisville: 0.75% vs 3.05%; Purdue University: 0.79% vs 2.97%; University of Michigan: 0.40% vs 1.12%; University of Illinois: 0.17% vs 0.40%; University of Virginia: 0.64% vs 1.04%) (P < .001 for each). The median (range) test positivity in these 9 schools was 0.46% (0.01%-0.79%) for student athletes and 1.04% (0.40%-6.58%) for nonathlete students. In 1 school, test positivity was increased in the student athlete group (Stanford University: 0.20% vs 0.05%; P < .001). Overall, there were 2425 positive tests (0.44%) among student athletes and 30 567 positive tests (0.88%) among nonathlete students, for a relative risk of 0.50 (95% CI, 0.48-0.52; P < .001). There was no statistically significant difference in student athlete test positivity between included schools; however, test positivity among nonathlete students varied considerably between institutions, ranging from 133 of 271 862 tests (0.05%) at Stanford University to 2129 of 32 336 tests (6.58%) at Penn State University. Conclusions and Relevance: This study found that in the setting of SARS-CoV-2 transmission mitigation protocols implemented by the NCAA, participation in intercollegiate athletics was not associated with increased SARS-CoV-2 test positivity. This finding suggests that collegiate athletics may be held without an associated increased risk of infection among student athletes.

Findings From Cardiovascular Evaluation of National Collegiate Athletic Association Division I Collegiate Student-Athletes After Asymptomatic or Mildly Symptomatic SARS-CoV-2 Infection.

OBJECTIVE: The risk of myocardial damage after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been controversial. The purpose of this study is to report the incidence of abnormal cardiovascular findings in National Collegiate Athletic Association (NCAA) Division I student-athletes with a history of SARS-CoV-2 infection. DESIGN: This is a case series of student-athletes with SARS-CoV-2 infection and their subsequent cardiac work-up, including troponin level, electrocardiogram, and echocardiogram. Additional testing was ordered as clinically indicated. SETTING: This study was conducted at a single NCAA Division I institution. PARTICIPANTS: Student-athletes were included if they tested positive for SARS-CoV-2 by PCR or antibody testing [immunoglobulin G (IgG)] from April 15, 2020 to October 31, 2020. INTERVENTION: Cardiac testing was conducted as part of postinfection screening. MAIN OUTCOME MEASURES: This study was designed to quantify abnormal cardiovascular screening results and cardiac diagnoses after SARS-CoV-2 infection in Division I collegiate athletes. RESULTS: Fifty-five student-athletes tested positive for SARS-CoV-2. Of these, 14 (26%) had a positive IgG and 41 (74%) had a positive PCR test. Eight abnormal cardiovascular screening evaluations necessitated further testing including cardiac magnetic resonance imaging (cMRI). Two athletes received new cardiac diagnoses, one probable early cardiomyopathy and one pericarditis, whereas the remaining 6 had normal cMRIs. CONCLUSIONS: These data support recent publications which recommend the de-escalation of cardiovascular testing such as cardiac MRI or echocardiogram for athletes who have recovered from asymptomatic or mildly symptomatic SARS-CoV-2 infection. Continued follow-up of these athletes for sequelae of SARS-CoV-2 is critical.

Increased Lower Extremity Injury Risk Associated With Player Load and Distance in Collegiate Women's Soccer.

BACKGROUND: There is limited research regarding the impact of workload on injury risk specific to women's soccer. Wearable global positioning system (GPS) units can track workload metrics such as total distance traveled and player load during games and training sessions. These metrics can be useful in predicting injury risk. PURPOSE: To examine the relationship between injury risk and player workload as collected from wearable GPS units in National Collegiate Athletic Association (NCAA) Division I women's soccer players. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Lower extremity injury incidence and GPS workload data (player load, total distance, and high-speed distance) for 65 NCAA Division I women's soccer players were collected over 3 seasons. Accumulated 1-, 2-, 3-, and 4-week loads and acute-to-chronic workload ratios (ACWR) were classified into discrete ranges by z-scores. ACWR was calculated using rolling averages and exponentially weighted moving averages (EWMA) models. Binary logistic regression models were used to compare the 7:28 rolling average and EWMA ACWRs between injured and noninjured players for all GPS/accelerometer variables. The prior 1-, 2-, 3-, and 4-week accumulated loads for all GPS/accelerometer variables were compared between the injured and uninjured cohorts using 2-sample t tests. RESULTS: There were a total of 53 lower extremity injuries that resulted in lost time recorded (5.76/1000 hours "on-legs" exposure time; 34 noncontact and 19 contact injuries). The prior 2-week (7242 vs 6613 m/s2; P = .02), 3-week (10,533 vs 9718 m/s2; P = .02), and 4-week (13,819 vs 12,892 m/s2; P = .04) accumulated player loads and 2-week (62.40 vs 57.25 km; P = .04), 3-week (90.97 vs 84.10 km; P = .03), and 4-week (119.31 vs 111.38 km; P = .05) accumulated total distances were significantly higher for injured players compared with noninjured players during the same time frames. There were no significant differences in player load, total distance, or high-speed distance ACWR between injured and noninjured players for both the rolling averages and EWMA calculations. CONCLUSION: Higher accumulated player load and total distance, but not ACWR, were associated with injury in women's soccer players.

Adenovirus Infection and Rhabdomyolysis as a Cause of Acute Liver Failure in a Healthy Collegiate Football Athlete: A Case Report and Proposed Return to Play Protocol for Rhabdomyolysis.

Adenovirus is a common cause of upper respiratory and gastrointestinal tract infections. Though cases of significant organ failure and death have been reported in young children and immunocompromised individuals, adenovirus infections in healthy individuals are typically self-limiting without significant morbidity or mortality. Exertional rhabdomyolysis is a pathologic condition resulting from repetitive, excessive, or prolonged exercise, often in a hot environment, leading to acute muscle injury, renal injury and, rarely, death. We report a case of adenovirus infection leading to acute liver failure complicated by rhabdomyolysis in a collegiate football player presenting with nausea, vomiting, and diarrhea. We propose a protocol to safely guide the return to play progression for patients with complicated exertional rhabdomyolysis.

High Specialization among Female Youth Soccer Players Is Associated with an Increased Likelihood of Serious Injury.

PURPOSE: This study aimed to assess the associations between serious injury (≥3-month time loss) and level of specialization among high-level female soccer players and to compare the specialization and college commitment ages of female youth soccer players to Division I college and professional soccer athletes. METHODS: Youth, college, and professional female soccer players in the United States playing in the top league at each level were recruited to complete an anonymous online survey. The survey collected information about player demographics, soccer specialization and training patterns, history of serious injuries from soccer, and perceptions surrounding soccer specialization. Comparisons between groups were performed using two-sample t-tests, χ2 analyses, and multiple logistic regression models controlling for differences in age. A P value of less than 0.05 was set as significant. RESULTS: A total of 1,018 (767 youth, 251 college/professional) athletes completed the survey. Serious injuries affected 23.6% of youth and 51.4% of college/professional athletes. Anterior cruciate ligament tears were more prevalent in college/professional players compared with youth athletes (18.3% vs 4.0%; P < 0.001). Highly specialized youth athletes (66.5%) were more likely to have sustained a serious injury from soccer compared with athletes with low specialization (odds ratio, 2.28 (1.38-3.92); P = 0.008) but not moderate specialization (odds ratio, 1.37 (0.83-2.27); P = 0.43). A higher proportion of youth athletes specialized at a young age (≤10 yr) compared with college/professional players (44.2% vs 25.9%; P < 0.001). CONCLUSIONS: High specialization in female youth soccer players is associated with an increased likelihood of sustaining a serious injury. Current youth soccer players are specializing earlier and committing to play college soccer at a younger age compared with when current college and professional players did.

Recommended Musculoskeletal and Sports Medicine Model Curriculum for Emergency Medicine Residency Training.

ABSTRACT: Musculoskeletal and sports medicine conditions are common in the emergency department (ED). Emergency physicians may not be receiving adequate education to achieve clinical competency in musculoskeletal medicine during residency training. This article aims to provide a standardized musculoskeletal and sports medicine curriculum for emergency medicine training. Broad curriculum goals include proficiency in evaluating and managing patients presenting to the ED with acute and chronic musculoskeletal complaints and other medical conditions related to or affected by physical exertion, sports participation, or environmental exposure. Specific objectives focus on knowledge of these disorders, physical examination skills, procedural skills including musculoskeletal ultrasound, appropriate consultation and referral, and patient education for these conditions. Educational methods will consist of didactics; online self-directed learning modules; simulation; and supervised clinical experiences in the ED, primary care sports medicine clinics, and orthopedic clinics if available. Curriculum implementation is expected to vary across programs due to differences in residency program structure and resources.

Calculated decisions: Ottawa ankle rule.

The Ottawa ankle rule shows the areas of tenderness to be evaluated in ankle trauma patients to determine the need for imaging.
