Olfactory dysfunction incidence and resolution amongst 608 patients with COVID-19 infection.

PURPOSE: Olfactory dysfunction (OD) is a common presenting sign of coronavirus-19 (COVID-19) infection and remains persistent in up to 7 % of patients one year after diagnosis. However, demographic, socioeconomic, and medical risk factors for persistent OD are not well understood. This study aims to determine risk factors for development and persistence of OD amongst patients with COVID-19 infection. MATERIALS AND METHODS: This prospective, observational questionnaire study was performed at a tertiary-level, academic center. Patients with history of a positive COVID-19 diagnosis were sent an online questionnaire. Patients' self-reported survey responses for OD and resolution were assessed for associations with demographic variables, socioeconomic factors, and clinical data. RESULTS: In total, 608 of 26,094 patients (77.6 % women, mean age 42.7 ± 17.4 years, range 9 months-92 years) completed the survey. OD was reported by 220 (36.2 %) patients, and 139 (63.2 %) patients achieved resolution. Patients with OD were more likely to have other sinonasal and flu-like symptoms, and had a hospitalization rate of 2.7 %. There were no significant differences in age, gender, occupational or residential factors, or medical comorbidities incidence of OD development. Women reported higher rates of persistent OD (88.9 % vs 77.0 %, p = 0.045). The OD recovery rates amongst active and resolved COVID-19 infections was 27.0 % and 70.0 %, respectively (p < 0.001). CONCLUSIONS: There was a low hospitalization rate amongst patients reporting OD. One-third of patients with COVID-19 self-reported OD, and two-thirds of patients achieve OD resolution. Survey respondents with active COVID-19 infection and female gender were more likely to report persistent OD.

Otolaryngology workforce trends by gender - When and where is the gap narrowing?

PURPOSE: To describe the changes in workforce gender distribution over time and characterize geographically where women are finding job opportunities within the field of otolaryngology. MATERIALS AND METHODS: The Centers for Medicare and Medicaid Services (CMS) publishes a Physician Compare National Downloadable File, which lists all active providers registered within CMS, as well as specialty, medical school graduation, and current practice location. The file of March 2021 was filtered for all providers that listed "otolaryngology" as their primary specialty. Providers were sorted based on medical school graduation year. Physicians were organized into five-year and ten-year quantiles, based on career experience. For each quantile, the gender distribution was recorded. For each decade of experience, the geographic distribution of gender was recorded at a state-by-state level. Descriptive statistics were conducted to characterize the number of female otolaryngologists per state. The geographic distribution of male versus female physicians was superimposed onto state boundary files as published by the U.S. Census Bureau using R Studio (2020) [13]. RESULTS: The Physician Compare National Database listed 1719 women (19.0%) and 7292 men (81.0%) otolaryngologists actively registered to practice in the United States. By career periods, the following proportions of otolaryngologists were women: 1-5 years, 317/971 (32.6%); 6-10 years, 417/1291 (32.3%); 11-15 years, 299/1159 (25.8%); 16-20 years, 207/1108 (18.7%); 21-25 years, 190/1156 (16.4%); 26-30 years, 138/1141 (12.1%); 31-35 years, 86/968 (8.9%); 36+ years, 60/1212 (5.0%). The linear regression of the male-female distribution data suggests that the proportion of men and women in practice in otolaryngology will equalize nationally in the 2030s. By geographic distribution, the mean and median number of female otolaryngologists per state was 34.3 (19.0%) and 21 (17.2%), respectively. The number of female otolaryngologists by state ranged from 2 (Idaho) to 258 (California). States with the lowest percentage of female otolaryngologists included Idaho (2/51, 3.9%), Oklahoma (5/86, 5.8%), and Utah (6/99, 6.1%). There has been a national increase in the percentage of women practicing in otolaryngology over the last several decades. CONCLUSIONS: There is a significantly higher proportion of female otolaryngologists within earlier practice years, which suggests that progress has been made toward closing the gender gap within this field. The geographic distribution of female otolaryngologists is highly variable and should be studied further to assess what factors contribute to more females choosing to practice in these regions to continue to build regional support networks for women within the field.

Incidence of synchronous malignancies found during triple endoscopy in head and neck cancer.

OBJECTIVES: To investigate the incidence of synchronous malignancies identified during triple endoscopy in patients with head and neck squamous cell carcinoma. METHODS: A retrospective chart review of patients from a tertiary academic medical center was performed. Patients with a primary head and neck squamous cell carcinoma who underwent triple endoscopy were included. Operative, radiographic, and pathology reports were reviewed to evaluate for the presence of synchronous malignancies in the aerodigestive tract diagnosed through endoscopy. Demographics, relevant medical history, including tobacco and alcohol use, and tumor characteristics were recorded. Univariate and multivariate regression analyses were conducted to assess for associations with synchronous malignancy on triple endoscopy. RESULTS: 215 patients were reviewed, 164 of which had a biopsy-positive head and neck squamous cell carcinoma and underwent triple endoscopy. Synchronous lesions were found in 8 patients (4.9%). Of the synchronous lesions, only two were identified on esophagoscopy and bronchoscopy; the remaining six were found on direct laryngoscopy. Clinical comorbidities including smoking and alcohol history, tumor p16 status, and tumor stage were not associated with presence of synchronous lesions. A positive synchronous lesion on positron emission tomography was significantly correlated with finding a synchronous lesion on triple endoscopy (p = 0.006). CONCLUSION: This study shows the incidence of synchronous lesions on triple endoscopy to be closer to 5%. While endoscopic examination can be useful in the anatomic characterization of head and neck malignancies, the low incidence of synchronous malignancies suggests that the need for triple endoscopy may be considered on a case-by-case basis.

Association of high ligation versus low ligation of the inferior mesenteric artery on anastomotic leak, postoperative complications, and mortality after minimally invasive surgery for distal sigmoid and rectal cancer.

BACKGROUND: In the treatment of distal sigmoid and rectal cancer, the appropriate level for the ligation of the inferior mesenteric artery (IMA) remains unresolved. High ligation divides the IMA proximally at its origin, and low ligation ligates the IMA distal to the origin of left colic artery. We assessed the association of level of ligation in scheduled minimally invasive resection of sigmoid and rectal cancers on anastomotic leak, postoperative complications, and death within 30 days. METHODS: We identified all patients with primary sigmoid and rectal cancer treated with scheduled minimally invasive resection and primary anastomosis between January 2002 and June 2018 using linked institutional and National Surgical Quality Improvement Program databases. We assessed the association of level of ligation with each outcome by fitting individual univariable and multivariable logistic regression models, adjusting for surgical approach, tumor location, neoadjuvant chemoradiotherapy, and Charlson comorbidity index. RESULTS: We included 158 patients treated with high ligation and 123 patients treated with low ligation. Overall, 12 patients had an anastomotic leak requiring intervention within 30 days: 5 in the high ligation group (3.2%, 95% CI 1.4-7.2%) and 7 in the low ligation group (5.7%, 95% CI 2.8-11.3%). There was no association between the level of ligation and anastomotic leak (unadjusted OR 1.85, 95% CI 0.58-6.38; adjusted OR 0.63, 95% CI 0.16-2.55). Similarly, there was no association between the level of ligation and reoperation for anastomotic leak (OR 1.29, 95% CI 0.15-10.9), major complications (Clavien-Dindo III-V; OR 2.22, 95% CI 0.90-5.77), minor complications (Clavien-Dindo I-II; OR 1.51, 95% CI 0.88-2.60), and all complications (OR 1.58, 95% CI 0.94-2.67). No deaths occurred in either group. CONCLUSIONS: There was no association of level of ligation of the IMA with anastomotic leak, postoperative complications as a composite, or death. The choice of high or low ligation of the IMA should be made based on technical factors such as length for the creation of a tension-free anastomosis.

Geospatial analysis of COVID-19 and otolaryngologists above age 60.

OBJECTIVE: The 2019 novel coronavirus (COVID-19) is disproportionately impacting older individuals and healthcare workers. Otolaryngologists are especially susceptible with the elevated risk of aerosolization and corresponding high viral loads. This study utilizes a geospatial analysis to illustrate the comparative risks of older otolaryngologists across the United States during the COVID-19 pandemic. METHODS AND MATERIALS: Demographic and state population data were extracted from the State Physician Workforce Reports published by the AAMC for the year 2018. A geospatial heat map of the United States was then constructed to illustrate the location of COVID-19 confirmed case counts and the distributions of ENTs over 60 years for each state. RESULTS: In 2018, out of a total of 9578 practicing U.S. ENT surgeons, 3081 were older than 60 years (32.2%). The states with the highest proportion of ENTs over 60 were Maine, Delaware, Hawaii, and Louisiana. The states with the highest ratios of confirmed COVID-19 cases to the number of total ENTs over 60 were New York, New Jersey, Massachusetts, and Michigan. CONCLUSIONS: Based on our models, New York, New Jersey, Massachusetts, and Michigan represent states where older ENTs may be the most susceptible to developing severe complications from nosocomial transmission of COVID-19 due to a combination of high COVID-19 case volumes and a high proportion of ENTs over 60 years.

"Hot Zones" for Otolaryngologists: Assessing the geographic distribution of aerosol-generating procedures amidst the COVID-19 pandemic.

OBJECTIVE: Given high COVID-19 viral load and aerosolization in the head and neck, otolaryngologists are subject to uniquely elevated viral exposure in most of their inpatient and outpatient procedures and interventions. While elective activity has halted across the board nationally, the slow plateau of COVID-19 case rates prompts the question of timing of resumption of clinical activity. We sought to prospectively predict geographical "hot zones" for otolaryngological exposure to COVID-19 based on procedural volumes data from 2013 to 2017. METHODS: Otolaryngologic CPT codes were stratified based on risk-level, according to recently published specialty-specific guidelines. Using the Medicare POSPUF database, aerosol-generating procedures (AGPs) were mapped based on hospital referral regions, against up-to-date COVID-19 case distribution data, as of April 24, 2020. RESULTS: The most common AGPs were diagnostic flexible laryngoscopy, diagnostic nasal endoscopy, and flexible laryngoscopy with stroboscopy. The regions with the most AGPs per otolaryngologist were Iowa City, IA, Detroit, MI, and Burlington, VT, while the states with the most COVID-19 cases as of April 24th are New York, New Jersey, and Massachusetts. CONCLUSIONS: Our study provides a model for predicting possible "hot zones" for otolaryngologic exposure based on both COVID-19 case density and AGP-density. As the focus shifts to resuming elective procedures, these potential "hot zones" need to be evaluated for appropriate risk-based decision-making, such as "reopening strategies" and allocation of resources.

A Reproducible Peritonsillar Abscess Incision and Drainage Model for Junior Trainees.

OBJECTIVES: To describe the design and construction of a reproducible, low-cost, peritonsillar abscess (PTA) incision and drainage simulator and assess its impact on trainees' confidence. METHODS: The 2-part simulator we developed consisted of a manikin head with a fixed, partially open mouth and a modular PTA mold. The mold is created by injecting a lotion and water mixture into plastic bubbles, followed by silicone solidification. Neodymium magnets secure the silicone-abscess packet to the manikin's palate. The simulator was utilized during an academic otolaryngology residency training program Annual Otolaryngology Boot Camp. A self-assessment Likert scale questionnaire was used to evaluate participants' confidence before and after simulator training. Fourth-year medical students and junior (first and second year) residents who participated in the boot camp and agreed to complete the evaluation were included. RESULTS: Three medical students, 17 PGY-1, and 10 PGY-2 residents agreed to complete the evaluation. All trainees agreed the model was useful for learning skills. The overall post-training confidence Likert scores of participants, and PGY-1 residents in particular, significantly improved compared to their pre-training scores (P < .001). CONCLUSIONS: Our model offers an affordable and efficient training opportunity for residents to enhance their competence in managing PTAs. This approach, with its simple yet effective design and low production cost, shows potential for scalability on a broader scale.

Reimbursement Trends in Pediatric Otolaryngology From 2000 to 2020: A CMS Physician Fee Schedule Analysis.

OBJECTIVE: The aim of this study was to evaluate the financial trends in Medicare reimbursement rates for the most billed procedures at a single institution from 2000 to 2020 within pediatric otolaryngology. STUDY DESIGN: Retrospective data analysis. SETTING: United States. METHODS: The most billed surgical and in-office procedures in pediatric otolaryngology at our institution were identified in the Physician Fee Schedule Look-up Tool from the Centers for Medicare and Medicaid Services to extract reimbursement data for each CPT code (Current Procedural Terminology). Monetary data were adjusted for inflation to 2020 US dollars per the changes to the consumer price index. Mean annual and total percentage changes in reimbursement were calculated by the adjusted values for all included procedures (N = 25). RESULTS: From 2000 to 2020, without adjusting for inflation, reimbursement for the most billed procedures increased by 10.9%, while the allocated relative value unit per procedure increased by 15.4%. However, when adjusted for inflation, reimbursement for these procedures decreased by 27.5% over the study period. CONCLUSIONS: The study findings identify a downward trend in reimbursement for the most billed procedures in pediatric otolaryngology at our institution. Given the low predominance of pediatric otolaryngology codes within Medicare reimbursement, these codes are rarely reviewed for accurate revaluation. It is imperative that our professional society remain active and engaged within this process to ensure quality delivery of care to our patients.

Geographic Distribution of Otolaryngology Training Programs and Potential Opportunities for Strategic Program Growth.

OBJECTIVE: To characterize the geographic distribution of US otolaryngology residents based on geographical population density to determine current status and identify potential opportunities for otolaryngology residency program expansion. METHODS: The locoregional population of otolaryngology residency programs was analyzed (as defined by the US Census) and the number of resident trainees per 100,000 people in each region was calculated. Otolaryngology residency program location was determined by mailing address, and program size was determined by AAMC public data. RESULTS: The average metropolitan city in the United States contained 2.07 otolaryngology trainees per 100,000 people. Cities with low trainee numbers per population included Phoenix, AZ (0.20 trainees per 100,000 people); Las Vegas, NV (0.26 per 100,000); Dallas, TX (0.26 per 100,000), Atlanta, GA (0.33 per 100,000); and Miami, FL (0.34 per 100,000). Comparing otolaryngology to other surgical subspecialties demonstrated similar distributions. Metropolitan centers with a population over 1 million without full academic representation in otolaryngology were also identified and included Charlotte, NC; Orlando, FL; Austin, TX; Providence, RI; Jacksonville, FL; Raleigh, NC; and Grand Rapids, MI. CONCLUSION: Strategic residency training program expansion should be considered in cities that exhibit a low trainee to population ratio. Although many factors ultimately determine program expansion or development of new training programs, this study provides substantiated population data describing where expansion could be prioritized. LEVEL OF EVIDENCE: NA Laryngoscope, 133:1600-1605, 2023.

A Systematic Review of Peritonsillar Abscess Simulators: Enhancing Training and Identifying the Need for Standardization.

OBJECTIVES: To systematically review the literature regarding previously described peritonsillar abscess (PTA) drainage simulation. DATA SOURCES: PubMed, Scopus, Web of Science, Ovid, and Cochrane. REVIEW METHODS: A search of the abovementioned databases was performed in August 2022 using the terms "peritonsillar abscess/quinsy," "incision/drainage/aspiration," and "simulation." No time restrictions were applied. We included studies that clearly described how their PTA models were built and underwent validation from experts and/or evaluation from trainees. Articles describing a model only without any evaluation and reports in languages other than English were excluded. RESULTS: Our search initially yielded 80 articles after duplicate removal, 10 of which met our criteria and were included. Two studies trained participants on both needle aspiration and incision and drainage (I&D), four studies on I&D only, and four on needle aspiration only. 87.5% to 100% of junior residents reported minimal exposure to PTA prior to simulation. Five studies provided some form of validation to their models. The value of the simulators to train participants on skills received better appreciation than their anatomical fidelity. The perceived confidence level of trainees in managing PTA, which was assessed in 7 studies, substantially improved after training. CONCLUSION: PTA simulation improves the confidence of trainees to perform PTA drainage. There is, however, a lack of standardization and evidence regarding transfer validity among PTA simulators. The development of a standardized PTA simulator could allow for more widespread use and increase resident comfort with this procedure in a pre-clinical setting. LEVEL OF EVIDENCE: NA Laryngoscope, 2023.

Loss to Follow-up in Head and Neck Cancer: A Systematic Review of Randomized Controlled Trials.

OBJECTIVE: To evaluate the reporting and rates of loss to follow-up (LTFU) in head and neck cancer (HNC) randomized controlled trials based in the United States. DATA SOURCES: Pubmed/MEDLINE, Cochrane, Scopus databases. REVIEW METHODS: A systematic review of titles in Pubmed/MEDLINE, Scopus, and Cochrane Library was performed. Inclusion criteria were US-based randomized controlled trials focused on the diagnosis, treatment, or prevention of HNC. Retrospective analyses and pilot studies were excluded. The mean age, patients randomized, publication details, trial sites, funding, and LTFU data were recorded. Reporting of participants through each stage of the trial was documented. Binary logistic regression was performed to evaluate associations between study characteristics and reporting LTFU. RESULTS: A total of 3255 titles were reviewed. Of these, 128 studies met the inclusion criteria for analysis. A total of 22,016 patients were randomized. The mean age of participants was 58.6 years. Overall, 35 studies (27.3%) reported LTFU, and the mean LTFU rate was 4.37%. With the exception of 2 statistical outliers, study characteristics including publication year, number of trial sites, journal discipline, funding source, and intervention type did not predict the odds of reporting LTFU. Compared to 95% of trials reporting participants at eligibility and 100% reporting randomization, only 47% and 57% reported on withdrawal and details of the analysis, respectively. CONCLUSION: The majority of clinical trials in HNC in the United States do not report LTFU, which inhibits the evaluation of attrition bias that may impact the interpretation of significant findings. Standardized reporting is needed to evaluate the generalizability of trial results to clinical practice.

An analysis of time to treatment in patients with pancreatic adenocarcinoma.

BACKGROUND: Currently, no guidelines exist regarding the appropriate time from diagnosis to treatment among pancreatic adenocarcinoma patients. Herein, we aim to define the median time to treatment in pancreatic adenocarcinoma, factors associated with treatment delay, and prognostic significance. METHODS: We conducted a retrospective study of pancreatic adenocarcinoma patients, stage I-IV, at a tertiary referral center (2017-2020). We subdivided time to treatment (days) into 4 components: (1) Ti: symptom onset to initial provider evaluation, (2) Tii: initial provider evaluation to diagnosis, (3) Tiii: diagnosis to specialist consultation, (4) Tiv: specialist visit to treatment. RESULTS: In total, 217 patients met the inclusion criteria. The median Ti, Tii, Tiii, and Tiv were 20, 12, 4, and 14 days, respectively. The total time to treatment was 75 days. Patients with weight loss had longer Ti (ß = 108.6). More frequent hospitalizations (ß = 19.5) and misdiagnosis (ß = 33.4) were associated with longer Tii. Patients with a history of malignancy (ß = 15) or active treatment of a second disease (ß = 19.4) had longer Tiii. Poor performance status (ß = 6.2) or private insurance (ß = 50.2) were associated with a longer Tiv. Black patients had longer Ti+ii+iii+iv (ß = 100). Time to treatment was not associated with overall survival (P > .05). CONCLUSION: It takes a median time of less than a month for a patient with pancreatic adenocarcinoma to start treatment, even after they visit a primary provider. The greatest opportunity to shorten the overall time to treatment is by having patients seek medical attention earlier (Ti).

Practice Consolidation in Otolaryngology: The Decline of the Single-Provider Practice.

OBJECTIVE: To observe trends in practice consolidation within otolaryngology by analyzing changes in size and geographic distribution of practices within the United States from 2014 to 2021. STUDY DESIGN: Retrospective analysis based on the Physician Compare National Database from the US Centers for Medicare and Medicaid Services. SETTING: United States. METHODS: Annual files from the Physician Compare National Database between 2014 and 2021 were filtered for all providers that listed "otolaryngology" as their primary specialty. Organization affiliations were sorted by size of practice and categorized into quantiles (1 or 2 providers, 3-9, 10-24, 25-49, and ≥50). Both the number of practices and the number of surgeons within a practice were collected annually for each quantile. Providers were also stratified geographically within the 9 US Census Bureau divisions. Chi-square analysis was conducted to test significance for the change in surgeon and practice distributions between 2014 and 2021. RESULTS: Over the study period, the number of active otolaryngology providers increased from 7763 to 9150, while the number of practices fell from 3584 to 3152 in that time span. Practices with just 1 or 2 otolaryngology providers accounted for 80.2% of all practices in 2014 and fell to 73.1% in 2021. Similar trends were observed at the individual provider level. Regional analysis revealed that New England had the largest percentage decrease in otolaryngologists employed by practices of 1 or 2 active providers at 45.7% and the Mountain region had the lowest percentage decrease at 17.4%. CONCLUSION: The otolaryngology practice marketplace has demonstrated a global trend toward practice consolidation.

Medicare reimbursement trends from 2000 to 2020 in head and neck surgical oncology.

BACKGROUND: Considering limited data exploring reimbursement trends at the subspecialty level within head and neck surgical oncology, we sought to characterize these trends for head and neck-specific codes from 2000 to 2020. METHODS: Using the Centers for Medicare and Medicaid Services' Physician Fee Schedule Look-Up Tool, reimbursement data, adjusted to 2020 U.S. dollars, for 37 head and neck surgical oncologic procedure codes were collected from 2000 to 2020. RESULTS: From 2000 to 2020, despite gross reimbursement for all head and neck procedures increasing by 23.2%, when adjusted for inflation, physician reimbursement decreased by 19.4%. Only 4 of 37 examined codes increased in net reimbursement over the study period. CONCLUSION: Medicare reimbursement for the most common head and neck oncologic procedure codes decreased from 2000 to 2020. Further research is necessary to explore the implications of these trends on the delivery of patient care.

Comparison of Publication Rates for Musculoskeletal Oncology Abstracts Presented at National Meetings.

BACKGROUND: Scientific meetings provide a forum to disseminate new research and advance patient care. The American Academy of Orthopaedic Surgeons (AAOS), Connective Tissue Oncology Society (CTOS), and Musculoskeletal Tumor Society (MSTS) annual meetings are examples of such gatherings in the field of musculoskeletal oncology. After a review of select MSTS abstracts from 1991 to 1999 revealed a 41% publication rate in scientific journals, previous authors cautioned meeting attendees that the majority of abstracts may not survive rigorous peer review and may not be scientifically valid. Since two decades have passed, this study reexamined publication rates and characteristics in a contemporary and expanded cohort of oncology abstracts presented at the AAOS, CTOS, and MSTS annual meetings. METHODS: 1408 podium and poster abstracts from the AAOS (oncology-focused from 2013 to 2015), CTOS (2012 to 2014), and MSTS (2012 to 2014) annual meetings were reviewed to allow for a four-year publication window. Searches were performed with PubMed and Google Scholar databases to identify full-text publications using abstract keywords. Characteristics of each abstract and resulting publication were collected. Statistical analysis was performed using the chi-square and Kruskal-Wallis tests for time-independent comparisons, and the log-rank test after reverse Kaplan-Meier analysis for time-dependent comparisons. RESULTS: Abstract publication rates overall were higher for podium presentations (67%, 280 of 415) compared to poster presentations (53%, 530 of 993; p < 0.001). When both abstract types were combined, differences between meetings did not meet statistical significance (AAOS: 65%, 106 of 162; CTOS: 57%, 521 of 909; MSTS: 54%, 183 of 337, p=0.06). Abstracts from AAOS meetings were more often published prior to the first day of the meeting (AAOS: 24%, 25 of 106; CTOS: 10%, 52 of 521; MSTS: 14%, 25 of 183; p < 0.01). After excluding previously published abstracts, AAOS abstracts had the shortest time to publication (median: 10.8 months, interquartile range (IQR): 4.4 to 18.8 months), compared to those from CTOS (16.0 months, 8.4 to 25.9 months, p < 0.01) and MSTS (15 months, 7.9 to 25.0 months, p < 0.01) meetings. CTOS abstracts were published in higher impact journals (median: 3.7, IQR: 2.9 to 5.9), compared to those from AAOS (2.9, 1.9 to 3.2, p < 0.01) and MSTS (3.1, 2.3 to 3.1, p < 0.01) meetings. Finally, 7.7% (62 of 810) of published abstracts were presented at more than one meeting. CONCLUSIONS: Publication rates in this study were higher than previous reports in musculoskeletal oncology and comparable or better than recent reports for other orthopedic meetings. Comparisons across the AAOS, CTOS, and MSTS annual meetings highlight notable differences but suggest similarity overall in the quality of evidence presented with little overlap between meetings. Taken together, this study points to progress in the review processes used by the program committees, reaffirms the importance of critical appraisal when considering abstract findings, and supports the continued organization of multiple scientific meetings in musculoskeletal oncology.

Computer-based video training is effective in teaching basic surgical skills to novices without faculty involvement using a self-directed, sequential and incremental program.

INTRODUCTION: Computer-based video training (CBVT) of surgical skills overcomes limitations of 1:1 instruction. We hypothesized that a self-directed CBVT program could teach novices by dividing basic surgical skills into sequential, easily-mastered steps. METHODS: We developed a 12 video program teaching basic knot tying and suturing skills introduced in discrete, incremental steps. Students were evaluated pre- and post-course with a self-assessment, a written exam and a skill assessment. RESULTS: Students (n = 221) who completed the course demonstrated significant improvement. Their average pre-course product quality score and assessment of technique using standard Global Rating Scale (GRS) were <0.4 for 6 measured skills (scale 0-5) and increased post-course to ≥3.25 except for the skill tying on tension whose GRS = 2.51. Average speed increased for all skills. Students' self-ratings (scale 1-5) increased from an average of 1.4 ± 0.7 pre-elective to 3.9 ± 0.9 post-elective across all skills (P < 0.01). CONCLUSION: Self-directed, incremental and sequential video training is effective teaching basic surgical skills and may be a model to teach other skills or to play a larger role in remote learning.

Benefits of minimally-invasive surgery for sigmoid and rectal cancer in older adults compared with younger adults: Do older adults have the most to gain?

INTRODUCTION: Randomized trials demonstrated oncologic safety and short-term benefits of laparoscopy. We investigated if the benefit of laparoscopy on short-term outcomes is greater for older adults compared with younger adults. METHODS: We identified all older (≥70 years old) and younger (<70) adults with primary sigmoid and rectal cancer treated with resection between 2002 and 2018 from an institutional database. We compared 30-day postoperative outcomes using multivariable logistic regression with an interaction term between age group and surgical approach. Primary outcomes were death, major (Clavien-Dindo III-IV) and minor (Clavien-Dindo I-II) complications, and wound complications. RESULTS: We included 792 patients, 293 (37%) older and 499 (63%) younger. Use of laparoscopy was similar between age groups: 120/293 (41%) older, 204/499 (41%) younger (p = .98). All patients had 30-day follow-up. Compared with open resection, minimally-invasive resection was associated with a greater reduction in deaths in older adults than in younger adults (absolute difference in older adults 7.0% less versus 2.1% less in younger adults; adjusted odds ratio [aOR] older 3.01, 95% confidence interval [CI] 1.31-7.33; aOR younger 0.31, 95% CI 0.05-1.24; interaction p = .01). Similarly, minimally-invasive resection was associated with a greater reduction in major complications in older adults than in younger adults (absolute difference in older adults 6.4% less versus 2.4% less in younger adults; aOR older 1.91, 95% CI 1.07-3.41; aOR younger 0.70, 95% CI 0.34-1.38; interaction p = .03). CONCLUSIONS: Minimally-invasive compared with open surgery demonstrated a differential benefit on postoperative death and major complications between younger and older adults.

A Multimodal Multi-institutional Solution to Remote Medical Student Education for Otolaryngology During COVID-19.

During the coronavirus 2019 pandemic, there has been a surge in production of remote learning materials for continued otolaryngology resident education. Medical students traditionally rely on elective and away subinternship experiences for exposure to the specialty. Delays and cancellation of clinical rotations have forced medical students to pursue opportunities outside of the traditional learning paradigm. In this commentary, we discuss the multi-institutional development of a robust syllabus for medical students using a multimodal collection of resources. Medical students collaborated with faculty and residents from 2 major academic centers to identify essential otolaryngology topics. High-quality, publicly available, and open-access content from multiple sources were incorporated into a curriculum that appeals to a variety of learners. Multimodal remote education strategies can be used as a foundation for further innovation aimed at developing tomorrow's otolaryngologists.

Midterm outcomes in patients with upper extremity deep vein thrombosis.

BACKGROUND: Outcomes and the necessity for anticoagulation in patients with upper extremity deep vein thrombosis (UE DVT) are unclear. The purpose of this study was to determine the incidence of UE DVT, the outcomes of patients stratified by anticoagulation treatment, and which factors were significantly associated with mortality. METHODS: This study was a single-center, retrospective review of all patients undergoing UE venous duplex imaging in 2016. Information on patients' demographics, relevant comorbidities, use of anticoagulation at the time of diagnosis, characteristics of the UE DVT, treatment regimen(s), and outcomes was collected. Data were analyzed using descriptive and univariate statistics; multivariate logistic regression and Cox proportional hazard models were used to identify which of the aforementioned covariates are significantly associated with mortality rates at 30 days and 6 months, respectively, at a 95% confidence level. RESULTS: Of the 911 patients undergoing UE venous duplex imaging, 182 (20.0%) were positive for UE DVT. Within the first 30 days, 30 patients (16.5%) died, 13 (7.1%) had pulmonary emboli, 42 (23.1%) had either pulmonary emboli or died, and 3 (1.6%) had ischemic strokes. Within the first 6 months, 50 patients (27.5%) died. The mortality rate at 30 days was found to be significantly increased in patients who were older (odds ratio [OR], 1.06; P < .01), had high-risk contraindications to anticoagulation (OR, 5.14; P < .01), were on dialysis (OR, 3.03; P = .04), had centrally located UE DVTs (OR, 2.72; P < .05), and had a stroke (OR, 20.34; P = .03). Mortality was significantly decreased in patients who were treated with anticoagulation (OR, 0.16; P < .05). At 6 months, however, age (hazard ratio [HR], 1.05; P < .001), male sex (HR, 2.16; P = .02), dialysis (HR, 2.90; P = .01), high-risk contraindications to anticoagulation (HR, 2.67; P = .02), UE DVTs in both central and peripheral veins (HR, 4.55; P = .03), and ischemic stroke in the first 30 days (HR, 71.63; P < .001) were associated with significant increases in mortality. CONCLUSIONS: These data suggest that mortality rates among patients with UE DVT are relatively high and that treatment with anticoagulation is associated with a decrease in mortality at 30 days. Mortality was also associated with multiple comorbid conditions and demographics and not necessarily venous thromboembolism.

Quantification of volumetric, surface area and linear airway changes after orthognathic surgery: a preliminary study.

PURPOSE: The aim of this study was to conduct a retrospective evaluation of the volumetric, cross-sectional surface area and the linear airway changes in healthy subjects undergoing orthognathic surgery. MATERIALS AND METHODS: A total of 10 patients were included in this study and categorized into two groups. The first group consisted of five patients who underwent maxillary and mandibular advancements (MMA) with genioplasty. The remaining five patients who underwent maxillary advancement with mandibular setback (MAMS) comprised the second group. The changes in airway volume, surface area, and linear values obtained from defined hard and soft tissue parameters were evaluated using preoperative and postoperative cone-beam computed tomography. A paired t-test was used to explore the statistical significance. RESULTS: A statistically significant increase in the airway volume (34.3%) was observed in the MMA group. The changes in the MAMS group were not statistically significant, although an average volumetric decrease of 8.8% was observed. The minimal axial surface area measurements in the MMA group at the levels of the soft palate and the tongue were significantly increased (56.8% and 44.9%, respectively). However, MAMS resulted in no significant changes at these levels (11.2% and 9.1% decrease, respectively). Linear changes showed a statistically significant increase in the airway in the MMA group, whereas the same measurements failed to produce significant changes in the MAMS group. CONCLUSION: As there were no significant changes in the measured parameters, surgeons can have greater confidence that MAMS does not have any negative influence on the airway.
