Representative Baseline Values on the Sport Concussion Assessment Tool 2 (SCAT2) in Adolescent Athletes Vary by Gender, Grade, and Concussion History

Background: To improve and standardize the sideline evaluation of sports-related concussion, the Sport Concussion Assessment Tool 2 (SCAT2) was developed. This tool assesses concussion-related signs and symptoms, cognition, balance, and coordination. This newly published assessment tool has not established representative baseline data on adolescent athletes. Hypothesis: Representative baseline SCAT2 scores in adolescent athletes will differ by gender, grade in school, and self-reported concussion history. Study Design: Descriptive epidemiology study. Methods: Interscholastic athletes were administered the SCAT2 during a preseason concussion baseline testing session. The SCAT2 total score ranges from 0 to 100 points, with lower scores indicating poorer performance. Overall, representative values were calculated using descriptive statistics. Separate independent-samples t tests, with gender and concussion history as the independent variables, and a 1-way analysis of variance, with grade as the independent variable, were conducted to assess differences in SCAT2 total score (P < .05). Results: There were 1134 high school athletes (872 male and 262 female) who participated. The SCAT2 total score across all participants was 88.3 ± 6.8 (range, 58-100); skewness was −0.86 ± 0.07, and kurtosis was 0.73 ± 0.14. Male athletes scored significantly lower on the SCAT2 total score (P = .03; 87.7 ± 6.8 vs 88.7 ± 6.8), and 9th graders (86.9 ± 6.8) scored significantly lower than 11th (88.7 ± 7.0) and 12th (89.0 ± 6.6) graders (P < .001). Athletes with a self-reported concussion history scored significantly lower on the SCAT2 total score than those with no concussion history (P < .001; 87.0 ± 6.8 vs 88.7 ± 6.5). Conclusion: These data provide representative scores on the SCAT2 in adolescent athletes and show that male athletes, 9th graders, and those with a self-reported concussion history scored significantly lower than their female, upperclassmen, or nonconcussed peers. Clinical Relevance: These results suggest that healthy adolescent athletes display variability on the SCAT2 at baseline. Therefore, clinicians should administer baseline assessments of the SCAT2 because assuming a perfect baseline score of 100 points is not appropriate in an adolescent athlete population.

A unique patient population? Health-related quality of life in adolescent athletes versus general, healthy adolescent individuals.

CONTEXT Normative scores for patient-rated outcome (PRO) instruments are important for providing patient-centered, whole-person care and making informed clinical decisions. Although normative values for the Pediatric Quality of Life Generic Core Scale (PedsQL) have been established in the general, healthy adolescent population, whether adolescent athletes demonstrate similar values is unclear. OBJECTIVE To compare PedsQL scores between adolescent athletes and general, healthy adolescent individuals. DESIGN Cross-sectional study. SETTING Secondary schools. PATIENTS OR OTHER PARTICIPANTS A convenience sample of 2659 interscholastic athletes (males = 2059, females = 600, age = 15.7 ± 1.1 years) represented the athlete group (ATH), and a previously published normative dataset represented the general, healthy adolescent group (GEN). INTERVENTION(S) All participants completed the PedsQL during 1 testing session. MAIN OUTCOME MEASURE(S) The PedsQL consists of 2 summary scores (total, psychosocial) and 4 subscale scores (physical, emotional, social, school), with higher scores indicating better health-related quality of life (HRQOL). Groups were stratified by age (14, 15, or 16 years old). Independent-samples t tests were conducted to compare between-groups and sex differences. RESULTS The ATH group scored higher than the GEN group across all ages for total and psychosocial summary scores and for emotional and social functioning subscale scores (P ≤ .005). For physical functioning, scores of the 15-year-old ATH were higher than for their GEN counterparts (P = .001). Both 14- and 15-year-old ATH scored higher than their GEN counterparts for the school functioning subscale (P ≤ .013), but differences between 16-year olds were not significant (P = .228). Male adolescent athletes reported higher scores than female adolescent athletes across all scores (P ≤ .001) except for social functioning (P = .229). CONCLUSIONS Adolescent athletes reported better HRQOL than GEN, particularly in emotional functioning. These findings further support the notion that ATH constitutes a unique population that requires its own set of normative values for self-reported, patient-rated outcome instruments.

Practice-Based Research Networks, Part II: A Descriptive Analysis of the Athletic Training Practice-Based Research Network in the Secondary School Setting

CONTEXT Analysis of health care service models requires the collection and evaluation of basic practice characterization data. Practice-based research networks (PBRNs) provide a framework for gathering data useful in characterizing clinical practice. OBJECTIVE To describe preliminary secondary school setting practice data from the Athletic Training Practice-Based Research Network (AT-PBRN). DESIGN Descriptive study. SETTING Secondary school athletic training facilities within the AT-PBRN. PATIENTS OR OTHER PARTICIPANTS Clinicians (n = 22) and their patients (n = 2523) from the AT-PBRN. MAIN OUTCOME MEASURE(S) A Web-based survey was used to obtain data on clinical practice site and clinician characteristics. Patient and practice characteristics were obtained via deidentified electronic medical record data collected between September 1, 2009, and April 1, 2011. Descriptive data regarding the clinician and CPS practice characteristics are reported as percentages and frequencies. Descriptive analysis of patient encounters and practice characteristic data was performed, with the percentages and frequencies of the type of injuries recorded at initial evaluation, type of treatment received at initial evaluation, daily treatment, and daily sign-in procedures. RESULTS The AT-PBRN had secondary school sites in 7 states, and most athletic trainers at those sites (78.2%) had less than 5 years of experience. The secondary school sites within the AT-PBRN documented 2523 patients treated across 3140 encounters. Patients most frequently sought care for a current injury (61.3%), followed by preventive services (24.0%), and new injuries (14.7%). The most common diagnoses were ankle sprain/strain (17.9%), hip sprain/strain (12.5%), concussion (12.0%), and knee pain (2.5%). The most frequent procedures were athletic trainer evaluation (53.9%), hot- or cold-pack application (26.0%), strapping (10.3%), and therapeutic exercise (5.7%). The median number of treatments per injury was 3 (interquartile range = 2, 4; range = 2-19). CONCLUSIONS These preliminary data describe services provided by clinicians within the AT-PBRN and demonstrate the usefulness of the PBRN model for obtaining such data.

Injury and Treatment Characteristics of Sport-Specific Injuries Sustained in Interscholastic Athletics: A Report From the Athletic Training Practice-Based Research Network

Background: The inclusion of clinical practice factors, beyond epidemiologic data, may help guide medical coverage and care decisions. Hypothesis: Trends in injury and treatment characteristics of sport-specific injuries sustained by secondary school athletes will differ based on sport. Study Design: Retrospective analysis of electronic patient records. Level of evidence: Level 4. Methods: Participants consisted of 3302 boys and 2293 girls who were diagnosed with a sport-related injury or condition during the study years. Injury (sport, body part, diagnosis via ICD-9 codes) and treatment (type, amount, and duration of care) characteristics were grouped by sport and reported using summary statistics. Results: Most injuries and treatments occurred in football, girls’ soccer, basketball, volleyball, and track and field. Sprain or strain of the ankle, knee, and thigh/hip/groin and concussion were the most commonly documented injuries across sports. The injury pattern for boys’ wrestling differed from other sports and included sprain or strain of the elbow and neck and general medical skin conditions. The most frequently reported service was athletic training evaluation/reevaluation treatment, followed by hot/cold pack, therapeutic exercise, manual therapy techniques, electrical stimulation, and strapping of lower extremity joints. Most sports required 4 to 5 services per injury. With the exception of boys’ soccer and girls’ softball, duration of care ranged from 10 to 14 days. Girls’ soccer and girls’ and boys’ track and field reported the longest durations of care. Conclusion: Injury and treatment characteristics are generally comparable across sports, suggesting that secondary school athletic trainers may diagnose and treat similar injuries regardless of sport. Clinical Relevance: Subtle sport trends, including skin conditions associated with boys’ wrestling and longer duration of care for girls’ soccer, are important to note when discussing appropriate medical coverage and care.

Early Operative Versus Delayed or Nonoperative Treatment of Anterior Cruciate Ligament Injuries in Pediatric Patients

UNLABELLED Reference: Ramski DE, Kanj WW, Franklin CC, Baldwin KD, Ganley TJ. Anterior cruciate ligament tears in children and adolescents: a meta-analysis of nonoperative versus operative treatment. Am J Sports Med. 2014;42(11):2769-2776. Clinical Questions: In pediatric patients, does early operative treatment of an anterior cruciate ligament (ACL) injury result in decreased knee instability compared with delayed or nonoperative treatment? DATA SOURCES This review focused on the PubMed/MEDLINE and EMBASE databases. The following query searches were used: ACL or anterior cruciate ligament and young or child or children or pediatric or immature. Dates searched were not specified. A separate search was also conducted of abstracts published between 2009 and 2011 from the American Academy of Orthopaedic Surgeons; American Orthopaedic Society for Sports Medicine; International Society of Arthroscopy, Knee Surgery, and Orthopaedic Sports Medicine; European Society of Sports Traumatology, Knee Surgery, and Arthroscopy; American Orthopaedic Association; Arthroscopy Association of North America; Pediatric Orthopaedic Society of North America; and American Academy of Pediatrics conferences. STUDY SELECTION Available studies were included only if they were written in English; were of level 1, 2, or 3 evidence (grading taxonomy not stated); were cohort designs that compared nonoperative and operative treatments; involved an early versus delayed ACL reconstruction that could be prospective or retrospective; and reported primary outcome interest measures. Animal studies, basic science studies, case series, reviews, commentaries, and editorials were excluded from the review. DATA EXTRACTION A systematic assessment tool, Guide to Community Preventive Services: Systematic Reviews and Evidence-Based Recommendations, was used by 2 of the authors to independently grade the quality of each study that met the inclusion criteria. The tool focused on 6 areas: intervention and study description, sampling, measurement, analysis, interpretation of results, and other execution factors. This tool helped to ensure consistency, reduce bias, and improve the validity and reliability of preventive health care studies. Eleven studies met the inclusion criteria. Six studies compared nonoperative with operative treatment, and 5 studies compared early reconstruction (open physes) with delayed reconstruction (closed physes). Studies in this meta-analysis consisted of the following: four level-3 prospective studies, four level-3 retrospective studies, one level-2 retrospective study, one level-3 case-control study, and one level-3 study with both prospective and retrospective data collection. All of the studies included data related to patient demographics, treatment interventions, follow-up duration, presence of any meniscal symptoms, time to return to sport participation, patient-reported outcomes (International Knee Documentation Committee [IKDC], Lysholm, or Tegner scores), the need for a second surgical procedure, and any posttreatment problems. MAIN RESULTS Of those who chose the nonoperative route, 75% reported instability, whereas only 13.6% of those who had surgery reported instability. These data also showed that nonoperative or delayed-operative patients were 33.7 times more likely to report instability than the early operative group. Those who chose the nonoperative route had a 12 times greater risk (odds ratio = 12.2, 95% confidence interval = 1.55, 96.3) of developing a meniscal tear after the initial injury. Three studies included in the meta-analysis reported return to sport status, but only 2 studies provided adequate data for both operative and nonoperative patients. In 1 study, 92% of operative patients were able to return to sport, but only 43.75% of nonoperative patients were able to do so. The second study reported that all operative and nonoperative patients were able to return to the same level of sport after injury. Of those in the early operative group, 6% required a repeat surgical intervention for either an ACL rerupture or a meniscal tear, and 19% of those who initially chose nonoperative treatment eventually needed surgery to repair the ACL or meniscus. Findings favor the early operative group over the delayed operative and nonoperative groups based on IKDC scores. One study reported a significant difference in operative patients, with an IKDC mean score of 95 compared with 87 in the nonoperative group. Similarly, a different study reported a mean score of 94.6 in the early operative group compared with 82.4 in the delayed operative group and was stated to have met the minimal clinically important difference (MCID). The MCID was not met for the Lysholm and Tegner scores between operative and nonoperative patients. CONCLUSIONS The results of this meta-analysis favor early operative treatment for pediatric patients with ACL tears over delayed or nonoperative treatment. Early operative treatment is initiated shortly after the injury, while the patient is still skeletally immature and the growth plates are open. Current evidence suggests that early ACL reconstruction will result in less knee instability and a more likely return to the preinjury activity level without affecting the growth plates or causing growth disturbances.

The impact of sex and knee injury history on jump-landing patterns in collegiate athletes: a clinical evaluation.

Objective:To determine whether jump-landing patterns, as assessed by the Landing Error Scoring System (LESS), differ based on sex and knee injury history. Design:Cross-sectional. Setting:College. Participants:Two hundred fifteen intercollegiate athletes were grouped by sex (male = 116 and female = 99) and self-reported knee injury history (no = 148, mild = 31, and severe = 36). Interventions:Participants performed 3 trials of a standardized jump-landing task that were videotaped and later scored using the LESS. Main Outcome Measures:Overall, individual item, sagittal total error, and frontal total error scores of the LESS. Results:An interaction effect was reported for trunk flexion at initial ground contact. Main effects for sex indicated that males demonstrated more at-risk landing movement patterns on the sagittal plane (ie, limited trunk, knee and hip flexion at initial contact, and limited hip flexion throughout the landing), whereas females demonstrated more at-risk landing movement patterns on the frontal plane (ie, knee valgus at initial ground contact and maximum knee flexion, and more frontal plane movement throughout the landing). No main effects were reported for injury history. Conclusions:Jump-landing patterns seem to be impacted by sex but not knee injury history. Findings related to sex differences corroborate with previous laboratory-based investigations. Furthermore, findings support the clinical use of the LESS to screen for individuals who may be at risk for a lower extremity injury. Future studies should further investigate the clinical utility of the LESS, particularly its ability to predict lower extremity injuries.

Previous Knee Injury and Health-Related Quality of Life in Collegiate Athletes.

CONTEXT   Patient-rated outcome measures (PROMs) capture changes that are important and meaningful to patients, such as health-related quality of life (HRQOL). Although group differences in HRQOL have been reported, little is known about the effect of injury history on HRQOL in collegiate athletes. OBJECTIVE   To determine whether knee-specific function (International Knee Documentation Committee Subjective Knee Evaluation Form [IKDC]) and HRQOL (Short Form 12 [SF-12]) differs in collegiate athletes based on sex and the severity of a previous knee injury. DESIGN   Cross-sectional study. SETTING   Athletic training facilities. PATIENTS OR OTHER PARTICIPANTS   Healthy collegiate athletes (n = 263) were grouped based on self-report of a previous knee injury: severe (n = 47), mild (n = 40), and no (n = 176) knee injury. INTERVENTION(S)   Participants completed the IKDC and SF-12 during their preparticipation examinations. MAIN OUTCOME MEASURE(S)   Generalized linear models were used to assess interactions and main effects of all scores. RESULTS   An interaction effect was observed for the SF-12 role physical subscale (P = .02), with men in the mild- and severe-injury groups reporting worse scores than men with no injury history. We noted a main effect for injury group for the IKDC total score (P < .001) and SF-12 physical functioning (P = .04) and role emotional (P = .04) subscales, with the severe-injury group reporting worse scores than the mild- and no-injury groups. No main effects of sex were reported (P > .05). CONCLUSIONS   Despite returning to full participation, collegiate athletes who previously sustained severe knee injuries tended to report worse knee-specific function and less ability to complete activities due to physical health. In addition, individuals with a history of severe knee injury tended to report more emotional concerns than athletes with a history of mild or no knee injury. Region-specific PROMs may be more sensitive in detecting deficits than generic PROMs after return to full participation. Researchers should investigate the role of PROMs, particularly region-specific PROMs, as potential screening tools for clinical care.

Athletic Training Services During Daily Patient Encounters: A Report From the Athletic Training Practice-Based Research Network

CONTEXT Athletic training services such as taping, wrapping, and stretching are common during routine care but rarely captured in traditional patient documentation. These clinical data are vital when determining appropriate medical coverage and demonstrating the value and worth of athletic trainers (ATs). OBJECTIVE To analyze clinical data from daily encounter forms within the Athletic Training Practice-Based Research Network (AT-PBRN). DESIGN Descriptive study. SETTING Secondary school athletic training clinics. PATIENTS OR OTHER PARTICIPANTS Adolescent patients (n = 4888; age = 16.3 ± 1.4 years) seeking care from ATs. MAIN OUTCOME MEASURE(S) We used Web-based electronic medical records from December 1, 2009, to July 1, 2015, to obtain patient characteristics via deidentified data. Descriptive data regarding practice characteristics from patient encounter forms were analyzed and reported as percentages and frequencies. RESULTS A total of 36 245 patient encounters (mean = 7.5 ± 11.6 encounters per patient) were recorded. Football, basketball, soccer, track, and volleyball accounted for 85.1% of all encounters. Most encounters were for preventive services (48.8%, n = 22 329), followed by care for a current injury (37.2%, n = 17 027) and care for a new injury (13.9%, n = 6368). Of the preventive encounters, taping (52.7%) was the most common service provided, followed by ice- or hot-pack application (25.4%) and treatment (9.6%). Taping (28.7%) was also the most common service for current injuries, followed by treatment (26.7%) and ice- or hot-pack application (26.2%). CONCLUSIONS Our findings highlight the unique role of ATs as health care providers who provide substantial preventive services to their patients. Further, these results represent one of the first attempts to describe athletic training services related to nontime-loss injuries, emphasizing the significant role that ATs play in the health care of secondary school athletes. These findings should help clinicians and administrators make more informed decisions regarding appropriate medical coverage.

Future Strategies to Enhance Patient Care Documentation Among Athletic Trainers: A Report from the Athletic Training Practice-Based Research Network

CONTEXT   High-quality patient care documentation is an essential component of any health care professionals daily practice. Whereas athletic trainers (ATs) recognize the importance of patient care documentation, several barriers may prevent them from producing high-quality patient care documentation. OBJECTIVE   To explore beneficial strategies and techniques that ATs perceived would enhance the quality of patient care documentation in the secondary school setting. DESIGN   Qualitative study. SETTING   Individual telephone interviews. PATIENTS OR OTHER PARTICIPANTS   Ten ATs who were members of the Athletic Training Practice-Based Research Network and employed in the secondary school setting were interviewed (4 men, 6 women with 7.1 ± 7.8 years of athletic training experience). DATA COLLECTION AND ANALYSIS   An individual telephone interview was conducted with each participant. Once transcribed, data were analyzed into common themes and categories per the consensual qualitative research tradition. Trustworthiness of the data was achieved through triangulation strategies: (1) the inclusion of multiple researchers to ensure accuracy and representativeness of the data and (2) participant member checking. RESULTS   Participants identified several documentation strategies they perceived would be helpful to improve the quality of patient care documentation, including mode and consistency of documentation and the need for a standardized process as well as the need for system standardization. In addition, participants discussed the need for more education on patient care documentation. Specifically, they identified ways of learning and strategies for future education to enhance patient care documentation across the profession. CONCLUSIONS   As athletic training continues to evolve, it is crucial that ATs are well educated on how to produce high-quality patient care documentation as a part of routine practice. Continuing professional development opportunities are needed to promote lifelong learning in the area of patient care documentation.
