Supporting Medical Education Innovation: Evaluation of a Grants Initiative.

PROBLEM: Medical education must evolve to meet the changing needs of patients and communities. Innovation is a critical component of that evolution. As medical educators pursue innovative curricula, assessments, and evaluation techniques, the impact of innovations may be limited by minimal funding. The American Medical Association (AMA) Innovation Grant Program, launched in 2018, seeks to address the gap in funding and stimulate educational innovation and research in medical education. APPROACH: In 2018 and 2019, the Innovation Grant Program targeted innovation in content areas including health systems science, competency-based medical education, coaching, learning environment, and emerging technology. The authors reviewed the content of applications and final reports for the 27 projects completed during the first 2 years of the program. They also noted measures of success (completion of project, achievement of grant objectives, development of transferrable educational product, dissemination). OUTCOMES: In 2018, the AMA received 52 submissions and funded 13 proposals, dispersing $290,000 ($10,000 and $30,000 grants). In 2019, the AMA received 80 submissions and funded 15 proposals, dispersing $345,000. Among the 27 completed grants, 17 (63%) supported innovations related to health systems science. Fifteen (56%) were used to create educational products that could be shared, such as new assessment tools, curricula, and teaching modules. Five grant recipients (29%) published articles and 15 (56%) presented at national conferences. NEXT STEPS: The grant program advanced educational innovations, particularly in health systems science. The next steps will involve examining the long-term outcomes and impact of the completed projects on medical students, patients, and the health system; the professional development of the grantees; and the adoption and dissemination of the innovations.

Knowledge, Awareness, and Attitudes Regarding Concussion Among Middle Schoolers.

INTRODUCTION:  Given the widespread prevalence of concussions in children under the age of 19, the adolescent perspective, as well as an understanding of the mechanisms behind traumatic brain injury (TBI), is extremely important. The authors sought to assess the knowledge, awareness, and attitudes regarding concussion among middle school children and whether a brief educational intervention based on clinical data and science resulted in a change of their knowledge or attitudes towards concussions. METHODS:  A 20-question survey design was administered before and after an educational intervention. The surveys were anonymous, but they were paired so that it was possible to correlate the pre- and post-test answers to the respondents. An eighth-grader at a Florida middle school conducted this study after school hours after the student and their parent or legal guardian signed informed consent. This project was approved by the Science Department at Howard Bishop Middle School in Alachua County, Florida. JMP® 14.0 (SAS Institute Inc., Cary, NC) was used for statistical analyses. RESULTS:  The cohort was 64% female, age range: 13 - 15, and consisted of local eighth-grade students. Forty-three percent never wore a helmet when riding a bicycle or skateboard. Only 68% knew that the state had a helmet law for kids. Participants were significantly more likely to feel they had good TBI knowledge after the intervention (p = 0.0005, 95% confidence interval (CI) 0.1937 to 0.6863) and that the didactic lectures changed the way they thought about safety (p = 0.0034, 95% CI 0.1025 to 0.5175). Students reported that their mothers (vs. fathers) were significantly more likely to wear seatbelts (p = 0.05, 95% CI 0.0036 to 0.5036), and they themselves reported wearing seatbelts more often after the survey. CONCLUSIONS:  There still exists a knowledge gap when it comes to pediatric concussion. Expanding awareness is important in order to bolster safety measures among adolescents.

GCS 15: when mild TBI isn't so mild.

OBJECTIVE: The present study characterizes patients with the mildest of mild traumatic brain injury (TBI), as defined by a Glasgow coma score (GCS) of 15. METHODS: This is an IRB approved observational cohort study of adult patients who presented to the emergency department of a Level-1 trauma center, with the primary diagnosis of TBI and a GCS score of 15 on arrival. Data collected included demographic variables such as age, gender, race, mechanisms of injury, signs and symptoms including associated vomiting, seizures, loss of consciousness (LOC), alteration of consciousness (AOC), and post-traumatic amnesia (PTA).Pre- hospital GCS, Emergency Department (ED) GCS, and results of brain CT scans were also collected as well as patient centered outcomes including hospital or intensive care unit (ICU) admission, neurosurgical intervention, and in hospital death. Data were stored in REDCap (Research Electronic Data Capture), a secure, web- based application. Descriptive and inferential analysis was done using JMP 14.0 for the Mac. RESULTS: Univariate predictors of hospital admission included LOC, AOC, and PTA, all p < 0.0001. Patients admitted to ICU were significantly more likely to be on an antiplatelet or anticoagulant (P < 0.0001), have experienced PTA (p = 0.0025), LOC (p < 0.0001), or have an abnormal brain CT (p < 0.0001). Patients who died in the hospital were significantly more likely to be on an antiplatelet or anticoagulant (P = 0.0005. All who died in the hospital had intracranial hemorrhage on ED head CT, despite having presented to the ED with GCS of 15. Patients were also significantly more likely to have had vomiting (p < 0.0001). Patients who underwent neurosurgical intervention were significantly more likely to be male (P = 0.0203), to be on an antiplatelet or anticoagulant (P = < 0.0001) likely to have suffered their TBI from a fall (P = 0.0349), and experienced vomiting afterwards (P = 0.0193). CONCLUSIONS: This study underscores: 1) the importance of neuroimaging in all patients with TBI, including those with a GCS 15. Fully 10% of our cohort was not imaged. Extrapolating, these would represent 2.5% bleeds, and 1.47% fractures. 2) The limitations of GCS in classifying TBI, as patients with even the mildest of mild TBI have a high frequency of gross CT abnormalities.

Differential inputs to striatal cholinergic and parvalbumin interneurons imply functional distinctions.

Striatal cholinergic (ChAT) and parvalbumin (PV) interneurons exert powerful influences on striatal function in health and disease, yet little is known about the organization of their inputs. Here using rabies tracing, electrophysiology and genetic tools, we compare the whole-brain inputs to these two types of striatal interneurons and dissect their functional connectivity in mice. ChAT interneurons receive a substantial cortical input from associative regions of cortex, such as the orbitofrontal cortex. Amongst subcortical inputs, a previously unknown inhibitory thalamic reticular nucleus input to striatal PV interneurons is identified. Additionally, the external segment of the globus pallidus targets striatal ChAT interneurons, which is sufficient to inhibit tonic ChAT interneuron firing. Finally, we describe a novel excitatory pathway from the pedunculopontine nucleus that innervates ChAT interneurons. These results establish the brain-wide direct inputs of two major types of striatal interneurons and allude to distinct roles in regulating striatal activity and controlling behavior.

The value of neurocognitive testing for acute outcomes after mild traumatic brain injury.

BACKGROUND: Traditionally, neurocognitive testing is performed weeks to months after head injury and is mostly performed on patients who continue to have symptoms or difficulties. In this study, we sought to determine whether these tests, when administered acutely, could assist in predicting short-term outcomes after acute traumatic brain injury (TBI). METHODS: This is an IRB-approved prospective study of adult patients who came to the emergency department of our Level-1 trauma center with TBI. Patients were enrolled prospectively after providing written informed consent and underwent three separate neurocognitive tests: the Galveston Orientation Amnesia Test (GOAT) the Rivermead Post-Concussion Survey Questionnaire (RPCSQ) and the Mini Mental Status Examination (MMSE). RESULTS: A lower GOAT score was significantly associated with hospitalization (P = 0.0212) and the development of post-concussion syndrome (P = 0.0081) at late follow-up. A higher RPCSQ score was significantly associated with hospital admission (P = 0.0098), re-admission within 30 days of discharge (P = 0.0431) and evidence of post-concussion syndrome (PCS) at early follow-up (P = 0.0004). A higher MMSE score was significantly associated with not being admitted to the hospital (P = 0.0002) and not returning to the emergency department (ED) within 72 hours of discharge (P = 0.0078). Lower MMSE was also significantly associated with bleeding or a fracture on the brain CT (P = 0.0431). CONCLUSIONS: While neurocognitive testing is not commonly performed in the ED in the setting of acute head injury, it is both feasible and appears to have value in predicting hospital admission and PCS. These data are especially important in terms of helping patients understand what to expect, thus, aiding in their recovery.

TBI ADAPTER: traumatic brain injury assessment diagnosis advocacy prevention and treatment from the emergency room--a prospective observational study.

There is no standard treatment algorithm for patients who present to the emergency department (ED) with acute traumatic brain injury (TBI). This is in part because of the heterogeneity of the injury pattern and the patient profile, and the lack of evidence-based guidelines, especially for mild TBI in adults. As TBI is seen more and more frequently in the ED, a standardized assessment would be beneficial in terms of efficiency. The authors present their ED approach to mild TBI evaluation in the ED, along with results to date. These data represent a prospective observational cohort study, where each patient provided individual, written informed consent.

Understanding Why Patients Return to the Emergency Department after Mild Traumatic Brain Injury within 72 Hours.

INTRODUCTION: Although there are approximately 1.1 million case presentations of mild traumatic brain injury (mTBI) in the emergency department (ED) each year, little data is available to clinicians to identify patients who are at risk for poor outcomes, including 72-hour ED return after discharge. An understanding of patients at risk for ED return visits during the hyperacute phase following head injury would allow ED providers to develop clinical interventions that reduce its occurrence and improve outcomes. METHODS: This institutional review board-approved consecutive cohort study collected injury and outcome variables on adults with the purpose of identifying positive predictors for 72-hour ED return visits in mTBI patients. RESULTS: Of 2,787 mTBI patients, 145 (5%) returned unexpectedly to the ED within 72 hours of hospital discharge. Positive predictors for ED return visits included being male (p=0.0298), being black (p=0.0456), having a lower prehospital Glasgow Coma Score (p=0.0335), suffering the injury due to a motor vehicle collision (p=0.0065), or having a bleed on head computed tomography (CT) (p=0.0334). ED return visits were not significantly associated with age, fracture on head CT, or symptomology following head trauma. Patients with return visits most commonly reported post-concussion syndrome (43.1%), pain (18.7%), and recall for further clinical evaluation (14.6%) as the reason for return. Of the 124 patients who returned to the ED within 72 hours, one out of five were admitted to the hospital for further care, with five requiring intensive care unit stays and four undergoing neurosurgery. CONCLUSION: Approximately 5% of adult patients who present to the ED for mTBI will return within 72 hours of discharge for further care. Clinicians should identify at-risk individuals during their initial visits and attempt to provide anticipatory guidance when possible.
