The Preparticipation Physical Evaluation.

The preparticipation physical evaluation (PPE) is a common reason for young athletes to see a primary care physician. An annual PPE is required by most state high school athletic associations for participation in school-based sports, although there is limited evidence to support its effectiveness for detecting conditions that predispose athletes to injury or illness. In 2019, the American Academy of Pediatrics, with representatives from the American Academy of Family Physicians and other organizations, published updated PPE recommendations (PPE5). According to the guideline, the general goals of the PPE are determining general physical and psychological health; evaluating for life-threatening or disabling conditions, including risk of sudden cardiac arrest and other conditions that may predispose the athlete to illness or injury; and serving as an entry point into the health care system for those without a medical home or primary care physician. The guideline recommends that the evaluation take place in the physician's office rather than in a group setting. The PPE should include a structured physical examination that focuses on the cardiovascular, musculoskeletal, and neurologic systems. Screening for depression, anxiety disorders, and attention-deficit/hyperactivity disorder is also recommended. Clinicians should recognize any findings suggestive of the relative energy deficiency in sport syndrome. Additional consideration is required to address the needs and concerns of transgender athletes and athletes with physical and intellectual disabilities. Finally, guidelines have been published regarding return to play for athletes who have had COVID-19.

Validation and Implementation of 4-domain Patient-reported Outcome Measures (PROMs) Tailored for Orthopedic Sports Medicine.

The validation of a 4-domain PROM tailored to orthopedic sports medicine was performed through item generation, item scaling, validity and reliability testing, statistical analysis, as well as item reduction. Conbrach's alpha was used to verify item homogeneity, i. e. their accuracy or consistency. This PROM showed acceptable statistical accuracy and clinical applicability for a variety of surgical treatments, regardless of the anatomical injury sites. Moreover, this PROM considers the athletes' primary physical demands in an non-injured baseline condition, their motivation to continue sports practice and participation, and the influence of sports practice on their quality of life. This 4-domain PROM tailored for orthopedic sports medicine appears to be a valid tool to assess athletes and high-performing practitioners with sports injuries, recording their perception of injury, expectations of treatment; evaluation of postoperative care and treatment received, and perceived outcomes compared to their pre-injury status of physical demands in sports activity. The tool is unique, allowing direct comparisons between athletes' perception of pre-injury baseline, injury, treatment, and outcome. It will be a welcome adjunct to the sports medicine professional's tool box when assessing athlete's status and outcome after injury and intervention.

Coronavirus Disease 2019 and the Athletic Heart: Emerging Perspectives on Pathology, Risks, and Return to Play.

Importance: Cardiac injury with attendant negative prognostic implications is common among patients hospitalized with coronavirus disease 2019 (COVID-19) infection. Whether cardiac injury, including myocarditis, also occurs with asymptomatic or mild-severity COVID-19 infection is uncertain. There is an ongoing concern about COVID-19-associated cardiac pathology among athletes because myocarditis is an important cause of sudden cardiac death during exercise. Observations: Prior to relaxation of stay-at-home orders in the US, the American College of Cardiology's Sports and Exercise Cardiology Section endorsed empirical consensus recommendations advising a conservative return-to-play approach, including cardiac risk stratification, for athletes in competitive sports who have recovered from COVID-19. Emerging observational data coupled with widely publicized reports of athletes in competitive sports with reported COVID-19-associated cardiac pathology suggest that myocardial injury may occur in cases of COVID-19 that are asymptomatic and of mild severity. In the absence of definitive data, there is ongoing uncertainty about the optimal approach to cardiovascular risk stratification of athletes in competitive sports following COVID-19 infection. Conclusions and Relevance: This report was designed to address the most common questions regarding COVID-19 and cardiac pathology in athletes in competitive sports, including the extension of return-to-play considerations to discrete populations of athletes not addressed in prior recommendations. Multicenter registry data documenting cardiovascular outcomes among athletes in competitive sports who have recovered from COVID-19 are currently being collected to determine the prevalence, severity, and clinical relevance of COVID-19-associated cardiac pathology and efficacy of targeted cardiovascular risk stratification. While we await these critical data, early experiences in the clinical oversight of athletes following COVID-19 infection provide an opportunity to address key areas of uncertainty relevant to cardiology and sports medicine practitioners.

Cardiovascular Screening of Elite Athletes by Sporting Organizations in Australia: A Survey of Chief Medical Officers.

OBJECTIVE: To compare cardiovascular screening policies of Australian elite sporting organizations. DESIGN: Online survey. SETTING: Elite/professional sports in Australia. PARTICIPANTS: Chief medical officers (CMOs) of elite/professional sports in Australia, including rugby union and league, cricket, tennis, Australian football, and cycling. ASSESSMENT OF VARIABLES: Survey questions about each sport's cardiac screening policy: which screening components were included [eg, history and physical (H&P), resting 12-lead electrocardiogram (ECG)], whether screening was mandatory, whether the policy applied to elite junior and/or adult players, and which criteria were used to interpret ECGs. MAIN OUTCOME MEASURES: Which sports had a formal cardiac screening policy, which athletes the policy applied to, components of screening, ECG interpretation criteria used. RESULTS: Chief medical officers for 22/31 (71%) sports responded, representing >5000 athletes. Of these, 19/22 (86%) perform regular screening (100% H&P; 89% included ECG) with international cyclists also having routine echocardiograms and stress testing. Thirty-three percent of CMOs used the 2017 International Criteria for athlete ECG interpretation. Screening was mandatory with enforcement (26%), mandatory without enforcement (48%), and opt-out (26%). All screened adult elite athletes, and 68% screened junior elite athletes. Forty-two percent indicated athletes were required to pay for screening tests, and 63% required athletes to pay for follow-up tests. Almost all (94%) sports with a sports physician as the CMO screened athletes. CONCLUSIONS: Most sports have a screening policy, with reasonable uniformity of components. All included H&P, and almost all included ECG. Only one sport included an echocardiogram and stress test as a standard (international players only). Promoting the latest ECG interpretation criteria may reduce false-positives and cost. Future work should explore cardiac emergency plans, screening infrastructure, cost, and long-term follow-up.

Low energy availability: history, definition and evidence of its endocrine, metabolic and physiological effects in prospective studies in females and males.

Energy availability (EA) is defined as the amount of dietary energy available to sustain physiological function after subtracting the energetic cost of exercise. Insufficient EA due to increased exercise, reduced energy intake, or a combination of both, is a potent disruptor of the endocrine milieu. As such, EA is conceived as a key etiological factor underlying a plethora of physiological dysregulations described in the female athlete triad, its male counterpart and the Relative Energy Deficiency in Sport models. Originally developed upon female-specific physiological responses, this concept has recently been extended to males, where experimental evidence is limited. The majority of data for all these models are from cross-sectional or observational studies where hypothesized chronic low energy availability (LEA) is linked to physiological maladaptation. However, the body of evidence determining causal effects of LEA on endocrine, and physiological function through prospective studies manipulating EA is comparatively small, with interventions typically lasting ≤ 5 days. Extending laboratory-based findings to the field requires recognition of the strengths and limitations of current knowledge. To aid this, this review will: (1) provide a brief historical overview of the origin of the concept in mammalian ecology through its evolution of algebraic calculations used in humans today, (2) Outline key differences from the 'energy balance' concept, (3) summarise and critically evaluate the effects of LEA on tissues/systems for which we now have evidence, namely: hormonal milieu, reproductive system endocrinology, bone metabolism and skeletal muscle; and finally (4) provide perspectives and suggestions for research upon identified knowledge gaps.

COVID-19-Myocarditis and Return to Play: Reflections and Recommendations From a Canadian Working Group.

The COVID-19-related pandemic has resulted in profound health, financial, and societal impacts. Organized sporting events, from recreational to the Olympic level, have been cancelled to both mitigate the spread of COVID-19 and protect athletes and highly active individuals from potential acute and long-term infection-associated harms. COVID-19 infection has been associated with increased cardiac morbidity and mortality. Myocarditis and late gadolinium enhancement as a result of COVID-19 infection have been confirmed. Correspondingly, myocarditis has been implicated in sudden cardiac death of athletes. A pragmatic approach is required to guide those who care for athletes and highly active persons with COVID-19 infection. Members of the Community and Athletic Cardiovascular Health Network (CATCHNet) and the writing group for the Canadian Cardiovascular Society/Canadian Heart Rhythm Society Joint Position Statement on the Cardiovascular Screening of Competitive Athletes recommend that highly active persons with suspected or confirmed COVID-19 infection refrain from exercise for 7 days after resolution of viral symptoms before gradual return to exercise. We do not recommend routine troponin testing, resting 12-lead electrocardiography, echocardiography, or cardiac magnetic resonance imaging before return to play. However, medical assessment including history and physical examination with consideration of resting electrocardiography and troponin can be considered in the athlete manifesting new active cardiac symptoms or a marked reduction in fitness. If concerning abnormalities are encountered at the initial medical assessment, then referral to a cardiologist who cares for athletes is recommended.

Roundtable on Preseason Heat Safety in Secondary School Athletics: Prehospital Care of Patients With Exertional Heat Stroke.

OBJECTIVE: First, we will update recommendations for the prehospital management and care of patients with exertional heat stroke (EHS) in the secondary school setting. Second, we provide action items to aid clinicians in developing best-practice documents and policies for EHS. Third, we supply practical strategies clinicians can use to implement best practice for EHS in the secondary school setting. DATA SOURCES: An interdisciplinary working group of scientists, physicians, and athletic trainers evaluated the current literature regarding the prehospital care of EHS patients in secondary schools and developed this narrative review. When published research was nonexistent, expert opinion and experience guided the development of recommendations for implementing life-saving strategies. The group evaluated and further refined the action-oriented recommendations using the Delphi method. CONCLUSIONS: Exertional heat stroke continues to be a leading cause of sudden death in young athletes and the physically active. This may be partly due to the numerous barriers and misconceptions about the best practice for diagnosing and treating patients with EHS. Exertional heat stroke is survivable if it is recognized early and appropriate measures are taken before patients are transported to hospitals for advanced medical care. Specifically, best practice for EHS evaluation and treatment includes early recognition of athletes with potential EHS, a rectal temperature measurement to confirm EHS, and cold-water immersion before transport to a hospital. With planning, communication, and persistence, clinicians can adopt these best-practice recommendations to aid in the recognition and treatment of patients with EHS in the secondary school setting.

Collegiate Student-Athletes' Perceptions of Patient-Centered Care Delivered by Athletic Trainers.

CONTEXT: The health care core competencies indicate that all medical professionals should provide patient-centered care (PCC), which is defined as care that is respectful and responsive to the patient's values and preferences, during each encounter. OBJECTIVE: To identify collegiate student-athletes' definitions of PCC and measure their perceived level of PCC from an athletic trainer (AT). DESIGN: Cross-sectional study. SETTING: Mixed-methods survey. PATIENTS OR OTHER PARTICIPANTS: A total of 610 (age = 19 ± 1 year) National Collegiate Athletic Association student-athletes completed the survey. MAIN OUTCOME MEASURE(S): The survey consisted of 1 open-ended question that prompted the participant to define PCC in his or her own words. The quantitative data were gathered using the Global Perceptions of Athletic Trainer PCC tool, which explores the overall agreement with the AT's use of PCC constructs. Finally, those participants who had received care from an AT completed the validated Patient Perception of Patient-Centeredness instrument. Qualitative analysis was completed through Text IQ technology with a mean sentiment score attributed to each of the coded statements. We calculated descriptive statistics for all quantitative data. RESULTS: The qualitative analysis revealed 13 topics, with the most used being individual, priority, and best. Other topics were inconsistent with how the medical community has defined PCC. On the Global Perceptions of Athletic Trainer PCC tool, the participants expressed strong agreement (mode = 4) with 12 of the 15 statements. On the Patient Perception of Patient-Centeredness instrument, participants expressed that the AT was completely (mode = 4) patient centered for all dimensions during their most recent encounter. However, PCC behaviors, as defined by the medical community, may not be directly expressed according to collegiate student-athletes. CONCLUSIONS: Student-athletes defined PCC as individualized and prioritized health care. They perceived that ATs provided care that kept their best interest in mind and practiced PCC during their encounters.

Methods of the National Athletic Treatment, Injury and Outcomes Network Surveillance Program (NATION-SP), 2014-2015 Through 2018-2019.

BACKGROUND: The National Athletic Treatment, Injury and Outcomes Network Surveillance Program (NATION-SP) was established in 2011 to provide a comprehensive appraisal of injuries sustained by high school student-athletes who received services from athletic trainers (ATs). The purpose of this article is to update the surveillance methods of the NATION-SP for data reported during the 2014-2015 through 2018-2019 academic years. SURVEILLANCE SYSTEM STRUCTURE: The NATION-SP used a rolling recruitment model to identify a convenience sample of US high schools with access to ATs. The ATs at participating institutions volunteered to contribute data via electronic medical records systems; common data elements were then pushed to and maintained by the Datalys Center for Sports Injury Research and Prevention. The ATs completed detailed reports on each injury, including the condition and circumstances. The treatments component was used to comprehensively assess the services provided to athletes by ATs. The outcomes companion component was developed to monitor patient-reported outcomes after athletic injury. SUMMARY: The NATION-SP continues to serve a critical purpose in informing injury-prevention and treatment efforts among high school athletes.

Pediatric PROMIS Computer Adaptive Tests Are Highly Correlated With Adult PROMIS Computer Adaptive Tests in Pediatric Sports Medicine Patients.

BACKGROUND: The Patient-Reported Outcomes Measurement Information System (PROMIS) is a powerful set of patient-reported outcome measures (PROMs) that are gaining popularity throughout orthopaedic surgery. The use of both adult and pediatric PROMIS questionnaires in orthopaedic sports medicine limits the value of the PROMIS in routine sports medicine clinical care, research, and quality improvement. Because orthopaedic sports medicine surgeons see patients across a wide age range, simplifying the collection of PROMIS computer adaptive tests (CATs) to a single set of questionnaires, regardless of age, is of notable value. PURPOSE/HYPOTHESIS: The purpose was to determine the strength of the correlation between the pediatric and adult PROMIS questionnaires. We hypothesized that there would be a high correlation between the adult and pediatric versions for each PROMIS domain, thereby justifying the use of only the adult version for most sports medicine providers, regardless of patient age. STUDY DESIGN: Cohort study (Diagnosis); Level of evidence, 2. METHODS: Between December 2018 and December 2019, all pediatric sports medicine patients presenting to a single, academic, orthopaedic sports medicine clinic were asked to participate in the present study with their parents' consent. Patients were asked to complete a set of adult PROMIS domains (Physical Function and/or Upper Extremity, Pain Interference, and Depression) as well as a set of pediatric PROMIS domains (Mobility and/or Upper Extremity, Pain Interference, and Depressive Symptoms). Concurrent validity was assessed using Pearson correlation coefficients (r). Ceiling and floor effects were determined. RESULTS: A total of 188 patients met our inclusion criteria. The correlation between the adult and pediatric PROMIS Upper Extremity, Physical Function and Mobility, Pain Interference, and Depression and Depressive Symptoms forms were high-moderate (r = 0.68; P < .01), high-moderate (r = 0.69; P < .01), high (r = 0.78; P < .01), and high (r = 0.85; P < .01), respectively. Both adult and pediatric depression-related PROMIS domains demonstrated notable floor effects (adult: 38%; pediatric: 24%). The pediatric PROMIS Upper Extremity domain demonstrated a ceiling effect (20%). CONCLUSION: Adult PROMIS CATs may be used in an orthopaedic sports medicine clinic for both adult and pediatric patients. Our findings will help decrease the amount of resources needed for the implementation and use of PROMs for patient care, research, and quality improvement in orthopaedic sports medicine clinics.

Looking to Improve Your Practice? Consider the Science of Quality Improvement to Get Started.

Quality improvement in health care is the responsibility of everyone (eg, patients, families, health providers, and administrative staff) to work toward delivering high-quality patient care, advancing professional knowledge and skills, and creating effective and efficient processes of care. Those involved in athletic health care, similar to other health care professionals, should strive to create patient care experiences that are safe, timely, effective, efficient, equitable, and patient centered. Exploring the differences between quality improvement and research will help define the focus of improvement sciences on the health of systems, which is to identify quality gaps and evaluate processes of care, as opposed to filling knowledge gaps. Furthermore, considering the principles of quality improvement will set the foundation for quality initiatives in health care to focus on patients, value teams, emphasize systems and processes of care, appreciate variability, and require data. With a greater understanding of the principles of the quality improvement sciences, athletic trainers will be better positioned to create a culture of quality improvement and to take the initiative in leading improvement efforts so that local systems support the delivery of high-quality patient care.

Variations in Athlete Heat-Loss Potential Between Hot-Dry and Warm-Humid Environments at Equivalent Wet-Bulb Globe Temperature Thresholds.

CONTEXT: Many organizations associated with sports medicine recommend using wet-bulb globe temperature (WBGT)-based activity-modification guidelines that are uniform across the country. However, no consideration has been given to whether the WBGT thresholds are appropriate for different weather conditions, such as warm-humid (WH) relative to hot-dry (HD), based on known differences in physiological responses to these environments. OBJECTIVE: To identify if personnel in regions with drier conditions and greater evaporative cooling potential should consider using WBGT-based activity-modification thresholds that differ from those in more humid weather. DESIGN: Observational study. SETTING: Weather stations across the contiguous United States. MAIN OUTCOME MEASURE(S): A 15-year hourly WBGT dataset from 217 weather stations across the contiguous United States was used to identify particular combinations of globe temperature, wet-bulb temperature, and air temperature that produce WBGTs of 27.9°C, 30.1°C, and 32.3°C. A total of 71 302 observations were clustered into HD and WH environmental conditions. From these clusters, maximum heat-loss potential and heat-flux values were modeled at equivalent WBGT thresholds with various activity levels, clothing, and equipment configurations. RESULTS: We identified strong geographic patterns, with HD conditions predominant in the western half and WH conditions predominant in the eastern half of the country. Heat loss was systematically greater in HD than in WH conditions, indicating an overall less stressful environment, even at equivalent WBGT values. At a WBGT of 32.3°C, this difference was 11 W·m-2 at an activity velocity of 0.3 m·s-1, which doubled for an activity velocity of 0.7 m·s-1. The HD and WH difference increased with the WBGT value, demonstrating that evaporative cooling differences between HD and WH conditions were even greater at a higher, rather than lower, WBGT. CONCLUSIONS: Potential heat loss was consistently greater in HD than in WH environments despite equal WBGTs. These findings support the need for further clinical studies to determine the appropriate WBGT thresholds based on environmental and physiological limits to maximize safety while avoiding unnecessary limitations.

Collision and Contact Sport Participation and Quality of Life Among Adolescent Athletes.

CONTEXT: Researchers investigating collision and contact sport participation during high school have found mixed results. Understanding the association between current contact and collision sport participation and quality-of-life outcomes can enhance our knowledge about the risks and benefits of sport participation. OBJECTIVE: To examine quality-of-life outcomes among high school athletes who reported participation in collision and contact sports in the year preceding assessment compared with no- or limited-contact sport athletes. DESIGN: Cross-sectional study. SETTING: Preparticipation physical examination. PATIENTS OR OTHER PARTICIPANTS: High school athletes 13 to 18 years of age. MAIN OUTCOME MEASURE(S): We obtained sport participation and Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric-25 outcomes, which assess self-reported, quality-of-life domains in the preceding 7 days (ie, state assessment). Our grouping variable was collision and contact versus no- or limited-contact sport participation during the year preceding assessment. We used multivariable linear regression models to identify the associations between PROMIS scores and collision and contact sport participation and adjusted for sex; age; history of bone, muscle, ligament, or tendon injury; history of acute fracture or dislocation; and history of concussion. RESULTS: A total of 143 (51%) athletes reported collision and contact sport participation (24% female, mean age = 15.1 ± 1.7 years) and 138 (49%) reported no- or limited-contact sport participation (66% female, mean age = 15.4 ± 1.2 years). A higher proportion of collision and contact sport athletes reported a history of time loss for bone, muscle, ligament, and tendon injuries (51% versus 29%, P < .001) and for acute fracture or dislocation (46% versus 26%, P < .001) than did no- or limited-contact athletes. After adjusting for covariates, we found that collision and contact sport participation was significantly associated with lower state anxiety (ß = -1.072, 95% confidence interval = -1.834, -0.310, P = .006) and depressive (ß = -0.807, 95% confidence interval = -1.484, -0.130, P = .020) symptom scores. CONCLUSIONS: Collision and contact sport athletes reported fewer anxiety and depressive symptoms in the week preceding evaluation than did no- or limited-contact sport athletes, but they had more extensive orthopaedic injury histories. Potential benefits and risks are associated with collision and contact sport participation. These data reinforce the need to examine the assumption that youth collision and contact sports are associated with negative quality of life.

Cardiorespiratory considerations for return-to-play in elite athletes after COVID-19 infection: a practical guide for sport and exercise medicine physicians.

SARS-CoV-2 is the causative virus responsible for the COVID-19 pandemic. This pandemic has necessitated that all professional and elite sport is either suspended, postponed or cancelled altogether to minimise the risk of viral spread. As infection rates drop and quarantine restrictions are lifted, the question how athletes can safely resume competitive sport is being asked. Given the rapidly evolving knowledge base about the virus and changing governmental and public health recommendations, a precise answer to this question is fraught with complexity and nuance. Without robust data to inform policy, return-to-play (RTP) decisions are especially difficult for elite athletes on the suspicion that the COVID-19 virus could result in significant cardiorespiratory compromise in a minority of afflicted athletes. There are now consistent reports of athletes reporting persistent and residual symptoms many weeks to months after initial COVID-19 infection. These symptoms include cough, tachycardia and extreme fatigue. To support safe RTP, we provide sport and exercise medicine physicians with practical recommendations on how to exclude cardiorespiratory complications of COVID-19 in elite athletes who place high demand on their cardiorespiratory system. As new evidence emerges, guidance for a safe RTP should be updated.
