Emergency department observation of mild traumatic brain injury with minor radiographic findings: shorter stays, less expensive, and no increased risk compared to hospital admission.

OBJECTIVE: The management of mild traumatic brain injury (mTBI) with minor radiographic findings traditionally involves hospital admission for monitoring, although this practice is expensive with unclear benefit. We implemented a protocol to manage these patients in our emergency department observation unit (EDOU), hypothesizing that this pathway was cost effective and not associated with any difference in clinical outcome. METHODS: mTBI patients with minor radiographic findings were managed under the EDOU protocol over a 3-year period from May 1, 2015 to April 30, 2018 (inclusions: ≥19 years old, isolated acute head trauma, normal neurological exam [except transient alteration in consciousness], and a computed tomography [CT] scan of the head with at least 1 of the following: cerebral contusions <1 cm in maximum extent, convexity subarachnoid hemorrhage, or closed, non-displaced skull fractures). These patients were retrospectively analyzed; clinical outcomes and charges were compared to a control cohort of matched mTBI hospital admissions over the preceding 3 years. RESULTS: Sixty patients were observed in the EDOU over the 3-year period, and 85 patients were identified for the control cohort. There were no differences in rate of radiographic progression, neurological exam change, or surgical intervention, and the overall incidence of hemorrhagic expansion was low in both groups. The EDOU group had a significantly faster time to interval CT scan (Mean Difference (MD) 3.92 hours, [95%CI 1.65, 6.19]), P = 0.001), shorter length of stay (MD 0.59 days [95% CI 0.29, 0.89], P = 0.001), and lower encounter charges (MD $3428.51 [95%CI 925.60, 5931.42], P = 0.008). There were no differences in 30-day re-admission, 30-day mortality, or delayed chronic subdural formation, although there was a high rate of loss to follow-up in both groups. CONCLUSIONS: Compared to hospital admission, observing mTBI patients with minor radiographic findings in the EDOU was associated with significantly shorter time to interval scanning, shorter length of stay, and lower encounter charges, but no difference in observed clinical outcome. The overall risk of hemorrhagic progression in this subset of mTBI was very low. Using this approach can reduce unnecessary admissions while potentially yielding patient care and economic benefits. When designing a protocol, close attention should be given to clear inclusion criteria and a formal mechanism for patient follow-up.

The 5 T's: Applying Cognitive Science to Improve Prehospital Medical Education.

Although research on effective teaching methods exists, the application of this information in prehospital medical education is limited. Applying lessons from the realms of cognitive psychology and neuroscience, prehospital educators can enhance their ability to teach. One such concept is the theory of cognitive load. Understanding this theory can reduce the mental strain placed on learners and allow educators to best accomplish long-term learning success, defined as "far transfer" of material to novel contexts. Thus, we propose 5 concise strategies gleaned from cognitive science literature: Tell a story, Time, Technical elements, Think novelly, and Testing and recall (referred to as the "5 T's"). Each strategy is grounded in research and applicable to medical education. Increased educator awareness and use of these strategies garners the potential to transform prehospital medical education.

Change IS Possible: Reducing High-Risk Drinking Using a Collaborative Improvement Model.

OBJECTIVE: To describe the adoption of public health and improvement methodologies to address college students' high-risk drinking behaviors and to aid in prevention efforts. PARTICIPANTS: Members of 32 colleges and universities, content experts, and staff members of the National College Health Improvement Program (NCHIP). METHODS: A 2-year learning collaborative developed by NCHIP trained individuals from 32 different college and universities in using the Plan-Do-Study-Act cycle as a method to create and implement initiatives aimed at reducing students' high-risk drinking behaviors and related harms. RESULTS: Participants experienced success ranging from noteworthy increases in type and amount of interventions directed at reducing high-risk drinking, to creating collaboratives across campus, the local community, and stakeholders. Challenges related to data collection and creating lasting cultural change remain. CONCLUSIONS: The use of quality improvement methodologies and creation of a national collaborative successfully effected meaningful change in high-risk drinking behaviors on college campuses.
