The study concept developed when Tammy Ng, MD, a third-year resident in pediatrics at the University of California, Davis, School of Medicine in Sacramento, was surprised to learn that the American Academy of Pediatrics (AAP) had been issuing a standard-of-care PPE for decades.
Dr. Ng had a long-standing interest in pediatric sports medicine and thought that if she was unfamiliar with this form, which was first developed by the AAP in the 1990s in collaboration with other professional organizations, there must be others who were unaware of this resource.
Assuming that this collaborative effort led by the AAP could serve as a standard of care, Dr. Ng evaluated whether PPEs at her own institution were capturing similar information.
In the most recent (5th) edition of the PPE, which was released in 2019 and is available online, medical history is elicited for numerous organ systems relevant to risk. The questions are not directed to any specific sport; the form does not even provide a question about which sports are being considered.
Little Consistency
In evaluating whether PPEs completed at her institution in the previous year elicited similar information, Dr. Ng sought to match 25 elements of patient history from the AAP form to questions posed in the PPEs completed at her institution, some of which had been supplied by school or sports organizations.
Of the 365 PPE forms completed at Dr. Ng’s institution that met study criteria, only 28.6% addressed all 25 elements in the AAP form (range, 0%-78%). Although more than half asked specifically about a history of respiratory symptoms, fewer than half included inquiries about cardiovascular history. There was also little consistency in the capture of information about other relevant medical history.
According to Dr. Ng, these low percentages were observed even when liberally awarding credit. For one example, she said forms that asked any question about syncope with exercise were credited with seeking information about cardiovascular health even though a yes-or-no response might not be helpful.
“We did not distinguish between syncope before or after exercise and this is relevant,” Dr. Ng said. “Syncope during exercise is more likely to be a predictor of sudden cardiac death, whereas syncope after exercise is more likely to be a vasovagal response to exertion.”
Of the 365 PPEs evaluated, about half were completed by pediatricians and half by family medicine clinicians. The average age of the children was about 14 years. Sixty-three percent were male. Only one third of the forms documented the sport for which a pre-participation screen was being submitted.
While almost all states now require PPEs for children considering participation in sports, few specify what information should be elicited, according to Dr. Ng. She further noted that no major study has shown that PPEs have any role in preventing morbidity or mortality related to sports participation.
Does Heterogeneity Negate Worth?
With such diversity across PPEs, evaluating their role is difficult. For example, with such heterogeneity among forms for the information elicited, there is no reasonable approach for testing their sensitivity in predicting medical complications.
Dr. Ng noted that school-created forms were just as likely as forms from other sources to diverge from the AAP-endorsed PPE and ignore organ systems relevant to risk of medical complications. Yet, if the answer is to use the AAP form, Dr. Ng noted that the first sentence on the form reads, “This form should be placed in the athlete’s medical file and should not be shared with schools or sports organizations.”
Although Dr. Ng acknowledged that providing completed PPEs to third parties raises questions about privacy, she questioned how the information should be used by children, parents, and sports organization administrators for discussing risks if not shared.
This concern was seconded in the discussion following Dr. Ng’s presentation.
“You might be signing off on sports participation, but is this for cheerleading or for football?” asked Daniel C. Worthington, MD, a pediatrician in private practice who has a clinical appointment at Case Western Reserve University School of Medicine, Cleveland. “This makes a huge difference when evaluating if participation is safe.”
He has no issue with completing PPEs for the goal of keeping children safe, but he focused on the inconsistency of how information is collected and distributed.
“The major question is: Does it make any difference?” said Dr. Worthington, referring to the completion of PPEs.
Another participant in the discussion that followed Dr. Ng’s presentation pointed out that the urgent care office in a mall near to his office offers a completed PPE form for a price of $20. In their recommendations, the AAP suggests PPEs be completed by the individual’s primary care physician during a well visit, according to Dr. Ng.
Dr. Ng indicated that PPEs and their purpose deserve a closer look. Based on her data, it is reasonable to assume that the priority for some – whether those requiring or those completing the form — is completing the task rather than meaningful screening of risk.
Dr. Ng and Dr. Worthington report no potential conflicts of interest.
