Development of a Surgical Video Atlas for Resident Education: 3-Year Experience.
Objective: To create a high-quality annotated online surgical video atlas of key indicator otolaryngology cases and assess its use and overall journal trends over time. Methods: Videos are recorded from multiple viewpoints within the operating room and compiled into a single stream. Postediting includes chaptering videos and overlaying relevant text annotations. Videos are published online and viewership trends analyzed. Results: Over 3 years, 29 otolaryngology videos were published out of 161 journal publications (18%). Eight of the 14 key indicator procedures are included (57%). From the beginning of 2017 to the end of 2019, viewership of otolaryngology pages increased from 548 to 11,139 views per month, totaling >150,000 views. These now represent 10% of the total journal monthly views and 10% of the overall views. Users originate from the United States and from >10 other countries. Discussion: Residents and faculty face challenges of providing the highest standard of clinical care, teaching, and learning in and out of the operating room. Inherent difficulties of surgical training, high-fidelity surgical simulation, and imposed work hour restrictions necessitate additional, more efficient and effective means of teaching and learning. Surgical videos demonstrating key anatomy, procedural steps, and surgical dexterity with hand positioning are increasing in their popularity among learners. Implications for Practice: Surgical video atlases provide a unique adjunct for resident education. They are enduring and easily accessible. In a climate of work hour restrictions or elective case reduction, they may supplement how residents learn to operate outside the operating theater.

The effect of lateral neck dissection on complication rate for total thyroidectomy.
PURPOSE: To determine the complication profile for total thyroidectomy with and without concomitant lateral neck dissection using a large administrative database. MATERIALS AND METHODS: The IBM MarketScan® Commercial Database (2010-2014) analytic cohort was queried for patients ≥18 years or older undergoing total thyroidectomy (or equivalent procedures) from January 1, 2010 to June 30, 2014. Subgroup analysis was performed for patients undergoing concomitant unilateral and bilateral lateral neck dissection. The complication profiles were described. RESULTS: 55,204 patients underwent total thyroidectomy or equivalent procedures. Hypoparathyroidism or hypocalcemia was coded in 20.3% overall, with 4.7% having permanent hypoparathyroidism. Vocal cord paralysis was coded in 3.3% overall with permanent rate of 0.7%. Tracheotomy was performed in 0.3% of patients. 2743 underwent total thyroidectomy with concomitant unilateral lateral neck dissection, and 560 of these patients underwent bilateral lateral neck dissection. In patients undergoing unilateral lateral neck dissection, 30.5% of patients have hypoparathyroidism/hypocalcemia coded, with a permanent rate of 8.8%. Vocal cord paralysis was coded in 8.3% of patients, with a permanent rate of 1.9%. Tracheotomy was performed in 1.2% of patients. In patients undergoing bilateral lateral neck dissection, 39.6% had hypoparathyroidism/hypocalcemia coded, with a permanent rate of 10.9%. These patients had vocal cord paralysis coded in 10.2% of cases, with a permanent rate of 2.1%. Tracheotomy was performed in 2.5% of patients. CONCLUSION: The addition of unilateral and especially bilateral lateral neck dissection increases both overall and permanent complication rates for total thyroidectomy. These data may help to inform preoperative discussions with patients.

Flow Cytometry Characterization of Cerebrospinal Fluid Monocytes in Patients With Postoperative Cognitive Dysfunction: A Pilot Study.
Animal models suggest postoperative cognitive dysfunction may be caused by brain monocyte influx. To study this in humans, we developed a flow cytometry panel to profile cerebrospinal fluid (CSF) samples collected before and after major noncardiac surgery in 5 patients ≥60 years of age who developed postoperative cognitive dysfunction and 5 matched controls who did not. We detected 12,654 ± 4895 cells/10 mL of CSF sample (mean ± SD). Patients who developed postoperative cognitive dysfunction showed an increased CSF monocyte/lymphocyte ratio and monocyte chemoattractant protein 1 receptor downregulation on CSF monocytes 24 hours after surgery. These pilot data demonstrate that CSF flow cytometry can be used to study mechanisms of postoperative neurocognitive dysfunction.

Establishing a Healthcare Research Network in Vietnam: A Platform for Collaborative Quality Improvement
© 2020, Springer Nature Singapore Pte Ltd. There is both a demand and need for delivering patient centered care in health systems. This is especially challenging in developing countries in which resources are limited, population health burdens are extensive, and coordination between facilities is fractured. The development of a low cost, centralized, real time data collection platform would be a powerful tool in understanding patient centered healthcare needs and issues. We report a pilot project that seeks to establish such a healthcare research network in Vietnam. This pilot used a web-based database collection tool called REDCap (Research Electronic Data Capture). We programmed a validated general health quality of life questionnaire in both English and Vietnamese that was used to collect patient responses. A total of four hospitals located in Hanoi, Vietnam participated in the pilot project of patients presenting with otolaryngology-head and neck complaints and concerns between January 23 and January 26, 2018. We report outpatient responses and their associated quality of life in ten specific domains. This pilot demonstrates the successful international collaboration among academic, non-profit, clinical entities in establishing this low-cost research network. This will be a platform that could easily be expanded to include other healthcare facilities in conducting quality improvement and research projects. We envision this approach as an important tool in improving health care quality in developing countries throughout the world.

CHEER National Study of Chronic Rhinosinusitis Practice Patterns: Disease Comorbidities and Factors Associated with Surgery.
Objectives (1) Describe national patterns of chronic rhinosinusitis (CRS) care across academic and community practices. (2) Determine the prevalence of comorbid disorders in CRS patients, including nasal polyposis, allergic rhinitis, asthma, and cystic fibrosis. (3) Identify demographic, clinical, and practice type factors associated with endoscopic sinus surgery (ESS). Study Design Multisite cross-sectional study. Setting Otolaryngology's national research network CHEER (Creating Healthcare Excellence through Education and Research). Subjects and Methods A total of 17,828 adult patients with CRS were identified, of which 10,434 were seen at community practices (59%, n = 8 sites) and 7394 at academic practices (41%, n = 10 sites). Multivariate logistic regression was used to evaluate the association between demographic, practice type, and clinical factors and the odds of a patient undergoing ESS. Results The average age was 50.4 years; 59.5% of patients were female; and 88.3% were Caucasian. The prevalence of comorbid diseases was as follows: allergic rhinitis (35.1%), nasal polyposis (13.3%), asthma (4.4%), and cystic fibrosis (0.2%). In addition, 24.8% of patients at academic centers underwent ESS, as compared with 12.3% at community sites. In multivariate analyses, nasal polyposis (odds ratio [OR], 4.28), cystic fibrosis (OR, 2.42), and academic site type (OR, 1.86) were associated with ESS ( P < .001), while adjusting for other factors. Conclusions We describe practice patterns of CRS care, as well as demographic and clinical factors associated with ESS. This is the first study of practice patterns in CRS utilizing the CHEER network and may be used to guide future research.
