Attending guidance advised: educational quality of surgical videos on YouTube.

INTRODUCTION: YouTube is the most used platform for case preparation by surgical trainees. Despite its popular use, studies have noted limitations in surgical technique, safety, and vetting of these videos. This study identified the most viewed laparoscopic cholecystectomy (LC) videos on YouTube and analyzed the ability of attendings, residents, and medical students to identify critical portions of the procedure, technique, and limitations of the videos. METHODS: An incognito search was conducted on YouTube using the term "laparoscopic cholecystectomy." Results were screened for length, publication date, and language. The top ten most viewed videos were presented to general surgery attendings, residents, and medical students at a single academic institution. Established rubrics were used for evaluation, including the Critical View of Safety (CVS) for LC, a modified Global Operative Assessment of Laparoscopic Skills (GOALS) score, a task-specific checklist, and visual analog scales for case difficulty and operator competence. Educational quality and likelihood of video recommendation for case preparation were evaluated using a Likert scale. Attending assessments were considered the gold standard. RESULTS: Six attending surgeons achieved excellent internal consistency on CVS, educational quality, and likelihood of recommendation scales, with Cronbach alpha (⍺) of 0.93, 0.92, and 0.92, respectively. ⍺ was ≥ 0.7 in all the other scales measured. Attending evaluations revealed that only one of the ten videos attained all three established CVS criteria. Four videos demonstrated none of the CVS criteria. The mean educational quality (mEQ) was 4.63 on a 10-point scale. The mean likelihood of recommendation (mLoR) for case preparation was 2.3 on a 5-point scale. Senior resident assessments (Postgraduate Year (PGY)4 + , n = 12) aligned with attending surgeons, with no statistically significant differences in CVS attainment, mEQ, and mLoR. Junior residents (PGY1-3, n = 17) and medical students (MS3-4, n = 20) exhibited significant difference with attendings in CVS attainment, mEQ, and mLoR for more than half the videos. Both groups tended to overrate videos compared to attendings. CONCLUSION: YouTube is the most popular unvetted resource used for case presentation by surgical trainees. Attending evaluations revealed that the most viewed LC videos on YouTube did not attain the CVS, and were deemed as inappropriate for case preparation, with low educational value. Senior resident video assessments closely aligned with attendings, while junior trainees were more likely to overstate video quality and value. Attending guidance and direction of trainees to high-quality, vetted resources for surgical case preparation is needed. This may also suggest a need for surgical societies with platforms for video sharing to prioritize the creation and dissemination of high-quality videos on easily accessible public platforms.

The use of a primary care provider survey to implement a fall prevention program in an urban hospital system.

BACKGROUND: Falls are the leading cause of traumatic injury in older adults. Multidisciplinary approaches between trauma surgeons and primary care providers can powerfully advocate for fall prevention. This study explores current fall prevention practices and barriers to falls screening and prevention in the primary care setting and proposes pertinent recommendations to address the deficiencies. METHODS: A questionnaire was adapted from a previous survey study to explore the beliefs, knowledge, attitudes, and clinical practice regarding falls by primary care providers. The questionnaire was distributed by e-mail to primary care providers at a tertiary urban medical center. RESULTS: The survey achieved a response rate of 58%. All respondents agreed that older adult patients should be assessed for fall risks and that evidence-based fall prevention programs can reduce the risk of falls. However, 43% of respondents did not agree that they had the expertise to perform fall risk assessments, and similarly 43% did not agree they have the time to perform fall risk assessments in the office. Furthermore, although 52% of respondents were aware of the Medicare reimbursement for fall risk screening, only 24% had billed for fall risk screening and only 5% agreed that they were adequately reimbursed. CONCLUSION: Several barriers to performing fall prevention care in the primary care setting were identified: unfamiliarity with resources, perceived lack of time, and perceived insufficient reimbursement. We implemented a set of interventions which include an educational series and workflow optimization to overcome barriers identified.

Configurable lipid membrane gradients quantify diffusion, phase separations and binding densities.

Single-experiment analysis of phospholipid compositional gradients reveals diffusion coefficients, phase separation parameters, and binding densities as a function of localized lipid mixture. Compositional gradients are formed by directed self assembly where rapid-prototyping techniques (i.e., additive manufacturing or laser-cutting) prescribe lipid geometries that self-spread, heal and mix by diffusion.
