ABSTRACTImportanceHighlighting the global disparities in otolaryngology training and, ultimately, service delivery, emphasizing the need for equitable access to training resources and programs.ObjectiveTo describe the relationship between the quality, content, and location of otolaryngology–head and neck surgery training and education and the resulting impact on the delivery of otolaryngology care globally.DesignAn online cross‐sectional survey to otolaryngologists, gathering information on their training and education experiences, and factors influencing their choice of training location and practice.SettingThe online survey was available in multiple languages, distributed via national and international professional otolaryngology societies, snowballing and social media.ParticipantsThe respondents were practicing otolaryngologists representing all seven World Health Organization regions.ExposuresWorld Bank income groups classification.Main Outcomes and MeasuresOur expected outcome was that subspecialty training and access to educational resources were significantly readily available to respondents from high‐income countries, leading to more confidence in performing complex procedures post training.ResultsA total of 91 participants were included in the analysis, with 47 (52%) practicing in high‐income countries and 44 (48%) in low‐ and middle‐income countries. Sixty‐one participants (67%) were male. Subspecialty training and access to educational resources were significantly less available in low‐ and middle‐income countries, leading to lower confidence among low‐ and middle‐income countries physicians in performing complex procedures. High‐income country respondents reported better access to diverse training resources and felt more prepared for a broader range of procedures.Conclusion and RelevanceSignificant disparities exist in OHNS training resources and subspecialty training opportunities between high‐ and low‐middle‐income countries. There is a critical need to integrate complementary training and educational modalities into local systems. Addressing the shortage of educational resources and promoting open‐access initiatives in low‐middle‐income countries are essential steps toward enhancing surgical education and improving global otolaryngology healthcare outcomes.

ABSTRACT Objective Availability of surgical equipment and access to essential clinical services remains an important barrier to surgical care delivery, particularly in low‐ and middle‐income countries (LMICs). This study aims to characterize the relative availability of essential equipment for otolaryngology‐head and neck surgery (OHNS) care across World Bank income groups. Methods We conducted a cross‐sectional survey on otolaryngologists' perceptions on the availability of surgical equipment and ancillary services in their respective practice settings per a 5‐point Likert scale ranging from never to always available. The study was disseminated online via professional societies, personal contacts, and social media. Eligible participants included otolaryngologists from 194 WHO‐recognized countries, which were grouped by World Bank income group classification and WHO region. Results The study involved 146 otolaryngologists, 69 (47%) from high‐income countries (HICs), and 77 (53%) from LMICs. LMIC respondents were predominantly from the African and South‐East Asian regions, which comprised 48% and 7.8% of all LMIC respondents, respectively. Results revealed significant differences in the availability of otologic, rhinologic, and endoscopic airway equipment between HICs and LMICs. Differences existed among commonly used equipment such as tympanomastoidectomy equipment and rigid bronchoscopy, to subspecialized equipment such as functional endoscopic sinus surgery equipment and cochlear implants ( p < 0.05 each). Conclusions The study highlighted key disparities in the availability of essential equipment for baseline OHNS care, especially for pediatric airway and otologic conditions. These results can be used to guide investment and advocacy efforts to improve specialty‐specific surgical infrastructure relative to the global burden of OHNS diseases in low‐resource settings.

Abstract Although social determinants of health (SDoH) investigations have shown limited analyses of socioeconomic and race-ethnic status on certain hematologic malignancies, the impact of factors beyond those across a fuller scope of hematologic cancers remains unknown. The Social Vulnerability Index (SVI), a tool for assessing varied US census–derived sociodemographic factors, allows for the specific quantification of SDoH in dynamic, regional contexts for their associations with hematologic malignancy inequities. To assess the summative influence of varied SDoH factors on hematologic malignancy outcomes and discern which SDoH factors contributed the largest associations toward disparities, 796 005 adults with hematologic malignancies between 1975 to 2017 were identified for this retrospective cohort study. Vulnerability in 15 SDoH factors was measured using composite and subcategory SVI scores geographically matched to patients. Regressions between SVI factors and follow-up time after diagnosis and survival period were performed. Increasing overall SVI correlated with significantly decreased surveillance period in 11 of 14 hematologic malignancies, with decreases upward of 33.4% (39.0-26.0 months for acute lymphocytic leukemia). Increasing SVI significantly associated with decreased survival period across 11 of 14 hematologic malignancies, with decreases upward of 47.2% (89.5-47.3 months for Hodgkin lymphoma). Socioeconomic status and housing and transportation vulnerabilities showed the largest magnitude of contributions, followed by minority language and household composition. Significant decreases in hematologic malignancy prognosis associate with increasing overall SDoH vulnerability in varied sociodemographic contexts in the United States. Furthermore, there are quantifiable differences in which types of SDoH contribute more to trends per malignancy type. These findings demonstrate specific SDoH targets for further research and policy initiatives to combat hematologic malignancy disparity more effectively.

AbstractObjectivesOnline educational platforms with open access have seen a growing adoption in the field of medical education. However, the extent of their global usage is still unclear. To fill this knowledge gap, our objective is to examine the usage patterns of two renowned open‐access resources in Otolaryngology. This includes identifying the most sought‐after topics and understanding the demographics of their users.MethodsRetrospective study of web analytics data between 2016 and 2021 extracted from the Headmirror.com and Mayo Clinic Otolaryngology YouTube channel platforms analyzing demographic and education topic trends via descriptive, geospatial, time‐series, t‐tests, and ANOVA analyses.ResultsViewership spanned 124 countries in 7 different geographic regions, with 72 countries comprising low‐ to middle‐income countries, mostly represented ages of 25–34 years old, came from high‐income countries rather than low‐income (p < .001), and used mobile phones followed by computers for device access. Video‐educational material comprised of subspecialty topics on Rhinology and Sinus Surgery (25%) at the highest end and Facial Trauma (1%) at the lowest. Controlling for the age of the video content, the most‐accessed videos comprised of subspecialty topics on Head and Neck Surgery at the highest end and Laryngology at the lowest with significant differentiation across topics of interest (p < .044).ConclusionsThis assessment of web‐analytics platforms from two widely used otolaryngology free, online‐access materials showed increasing global usage trends with significant differentiating factors along viewership demographics, as well as sought‐after subspecialty topics of interest. In turn, our results not only lay the groundwork for characterizing the global otolaryngology audience but also for future development of targeted educational materials and accessibility initiatives aimed at ameliorating global educational disparities in the field.

6526 Background: In the current literature, the association between social determinants of health (SDH) and head & neck-nervous system cancer (HNNsC) is limited by the narrow scope of SDH assessed and the broad classifications of HNNsC. Our study utilizes the CDC-Social Vulnerability Index (SVI) to assess both the individual and collective impact of four social determinant themes on various HNNsC in US adults. Methods: This study utilized the SEER database to evaluate 116,373 adult patients from 1975-2017 who presented with HNNsC. Patients were assigned SVI scores based on county-of-residence at the time of diagnosis, encompassing total-SVI score and 4 sub-scores of socioeconomic status, minority-language status, household composition, and housing-transportation. Using these scores, univariate linear regressions were used to assess patient care (months of follow-up) and prognosis (months of survival). Results: As total-SVI score increased, decreases in months of follow-up (MOF) and months of survival (MOS) were observed for many HNNsC tumors (p less than 0.001) when comparing the lowest to highest vulnerability cohorts. There was a decrease ranging from 3.55-36.6% in the MOF, with the largest decreases occurring in embryonal, anaplastic oligodendroglioma, and anaplastic ependymoma tumor types, with the largest sub-score contribution coming from socioeconomic status for these three disease classes. Similarly, there was a decrease ranging from 6.90-45.81% in the MOS, with the largest decreases occurring in anaplastic ependymoma, anaplastic astrocytoma, and pilocytic astrocytoma tumor types with the largest sub-score contribution coming from socioeconomic status for these three disease classes. Increases in vulnerability within SDH themes contributed significantly to these total-SVI trends in MOF and MOS, with each social determinant impacting different disease classes to varying extents. Socioeconomic status was the most impactful sub-score for MOF in nine of fourteen disease classes, followed by housing-transportation and household composition, each leading the impact of two of fourteen disease classes, and minority-language status leading the impact of one of fourteen disease classes. Similarly, socioeconomic status was the most impactful sub-score for MOS in eight of fourteen disease classes, followed by housing-transportation leading the impact of three of fourteen disease classes, household composition leading the impact of two of fourteen disease classes, and minority-language status leading the impact of one of fourteen disease classes. Conclusions: The results of this study show that with increasing social vulnerability, there is a significant decrease in both the care (follow-up) and the prognosis (survival) of US adults with HNNsC and highlight which SDH contributes more to disparities.

AbstractObjectivesTo create an otolaryngology‐specific needs assessment tool for short‐term global surgical trips and to describe our findings from its implementation.MethodsSurveys 1 and 2 were developed based on a literature review and disseminated to Low‐Middle Income (LMIC) hosting institutions in Kenya and Ethiopia and to High‐Income surgical trip participants (HIC), respectively. Respondents were otolaryngologists identified online, through professional organizations, and by word‐of‐mouth, who had participated in a surgical trip of <4 weeks.ResultsHIC and LMIC respondents shared similar goals of expanding host surgical skills through education and training while building sustainable partnerships. Discrepancies were identified between LMIC desired surgical skills and supply needs and HIC current practices. Microvascular reconstruction (17.6%), advanced otologic surgery (17.6%), and FESS (14.7%) were most desired skills and high‐demand equipment needs were FESS sets (89%), endoscopes (78%), and surgical drills (56%). Frequently taught techniques included advanced otologic surgery (36.6%), congenital anomaly surgery (14.6%), and FESS (14.6%) with the largest gap between LMIC‐need and HIC‐offerings being in microvascular reconstruction (17.6% vs. 0%). We also highlight the discrepancy in expectations of responsibility for trip logistics, research, and patient follow‐up.ConclusionWe created and implemented the first otolaryngology‐specific needs assessment tool in the literature. With its implementation in Ethiopia and Kenya, we were able to identify unmet needs as well as attitudes and perceptions of LMIC and HIC participants. This tool may be adapted and utilized to assess specific needs, resources, and goals of both host and visiting teams to facilitate successful global partnerships.Level of EvidenceLevel VI.
