IMPORTANCE-Mild traumatic brain injury (mTBI), or concussion, in children is a rapidly growing public health concern because epidemiologic data indicate a marked increase in the number of emergency department visits for mTBI over the past decade. However, no evidencebased clinical guidelines have been developed to date for diagnosing and managing pediatric mTBI in the United States.OBJECTIVE-To provide a guideline based on a previous systematic review of the literature to obtain and assess evidence toward developing clinical recommendations for health care professionals related to the diagnosis, prognosis, and management/treatment of pediatric mTBI. EVIDENCE REVIEW-The Centers for Disease Control and Prevention (CDC) National Center for Injury Prevention and Control Board of Scientific Counselors, a federal advisory committee, established the Pediatric Mild Traumatic Brain Injury Guideline Workgroup. The workgroup drafted recommendations based on the evidence that was obtained and assessed within the systematic review, as well as related evidence, scientific principles, and expert inference. This information includes selected studies published since the evidence review was conducted that were Lumba-Brown et al.

In recent years, there has been an exponential increase in the research guiding pediatric mild traumatic brain injury (mTBI) clinical management, in large part because of heightened concerns about the consequences of mTBI, also known as concussion, in children. The CDC National Center for Injury Prevention and Control's (NCIPC) Board of Scientific Counselors (BSC), a federal advisory committee, established the Pediatric Mild TBI Guideline workgroup to complete this systematic review summarizing the first 25 years of literature in this field of study. OBJECTIVE To conduct a systematic review of the pediatric mTBI literature to serve as the foundation for an evidence-based guideline with clinical recommendations associated with the diagnosis and management of pediatric mTBI. EVIDENCE REVIEW Using a modified Delphi process, the authors selected 6 clinical questions on diagnosis, prognosis, and management or treatment of pediatric mTBI. Two consecutive searches were conducted on PubMed, Embase, ERIC, CINAHL, and SportDiscus. The first

ABSTRACT. Objective. More than 25 million children in the United States are dependent on federal and state medical insurance programs for their health care needs. In California, 3.25 million children depend on Medi-Cal for their health insurance. In Southern California alone, the figure is as high as 1.81 million. However, 9.30 million children nationally and 1.55 million in California have no health insurance. Various public policies that would increase enrollment in these programs are being discussed to address this problem. However, before their implementation, it is important to understand what impact such policies would have on the actual delivery of health care to this patient population. In California, 2 predominant health care delivery models exist for Medi-Cal: a fee-for-service (so-called regular or straight Medi-Cal) and a managed care plan. One third of the children in Medi-Cal in the state are enrolled in the fee-for-service plan with the remainder in the managed care plan, whereas in Southern California, this figure is slightly lower at 28% in the fee-for-service plan. The objective of this study was to determine the number of otolaryngologists in Southern California who would offer a new patient appointment for an evaluation for tonsillectomy for a child with commercial insurance versus government-funded (Medi-Cal) insurance through direct contact with the physician and to determine whether the surgeon would offer to perform the procedure or refer the patient to another institution and to identify the specific reason(s) for any disparity in access to health care. Methods. A written questionnaire was sent via regular mail to 303 otolaryngologists in the Southern
