Abstract Background In the 5 years that have passed since the publication of the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (ICAR‐Allergic Rhinitis 2018), the literature has expanded substantially. The ICAR‐Allergic Rhinitis 2023 update presents 144 individual topics on allergic rhinitis (AR), expanded by over 40 topics from the 2018 document. Originally presented topics from 2018 have also been reviewed and updated. The executive summary highlights key evidence‐based findings and recommendation from the full document. Methods ICAR‐Allergic Rhinitis 2023 employed established evidence‐based review with recommendation (EBRR) methodology to individually evaluate each topic. Stepwise iterative peer review and consensus was performed for each topic. The final document was then collated and includes the results of this work. Results ICAR‐Allergic Rhinitis 2023 includes 10 major content areas and 144 individual topics related to AR. For a substantial proportion of topics included, an aggregate grade of evidence is presented, which is determined by collating the levels of evidence for each available study identified in the literature. For topics in which a diagnostic or therapeutic intervention is considered, a recommendation summary is presented, which considers the aggregate grade of evidence, benefit, harm, and cost. Conclusion The ICAR‐Allergic Rhinitis 2023 update provides a comprehensive evaluation of AR and the currently available evidence. It is this evidence that contributes to our current knowledge base and recommendations for patient evaluation and treatment.

Abstract The North American Airway Collaborative (NoAAC) previously published a 3‐year multi‐institutional prospective cohort study showing variation in treatment effectiveness between 3 primary surgical techniques for idiopathic subglottic stenosis (iSGS). In this report, we update these findings to include 5 years of data evaluating treatment effectiveness. Patients in the NoAAC cohort were re‐enrolled for 2 additional years and followed using the prespecified published protocol. Consistent with prior data, prospective observation of 487 iSGS patients for 5 years showed treatment effectiveness differed by modality. Cricotracheal resection maintained the lowest rate of recurrent operation (5%), followed by endoscopic resection with adjuvant medical therapy (30%) and endoscopic dilation (50%). These data support the initial observations and continue to provide value to providers and patients navigating longitudinal decision‐making. Level of evidence: 2—prospective cohort study.

Objectives: To examine whether social determinants of health (SDH) factors are associated with time to diagnosis, treatment selection, and time to recurrent surgical intervention in idiopathic subglottic stenosis (iSGS) patients. Methods: Adult patients with diagnosed iSGS were recruited prospectively (2015-2017) via clinical providers as part of the North American Airway Collaborative (NoAAC) and via an online iSGS support community on Facebook. Patient-specific SDH factors included highest educational attainment (self-reported), median household income (matched from home zip code via U.S. Census data), and number of close friends (self-reported) as a measure of social support. Main outcomes of interest were time to disease diagnosis (years from symptom onset), treatment selection (endoscopic dilation [ED] vs cricotracheal resection [CTR] vs endoscopic resection with adjuvant medical therapy [ERMT]), and time to recurrent surgical intervention (number of days from initial surgical procedure) as a surrogate for disease recurrence. Results: The total 810 participants were 98.5% female, 97.2% Caucasian, and had a median age of 50 years (IQR, 43-58). The cohort had a median household income of $62 307 (IQR, $50 345-$79 773), a median of 7 close friends (IQR, 4-10), and 64.7% of patients completed college or graduate school. Education, income, and number of friends were not associated with time to diagnosis via multivariable linear regression modeling. Univariable multinominal logistic regression demonstrated an association between education and income for selecting ED versus ERMT, but no associations were noted for CTR. No associations were noted for time to recurrent surgical procedure via Kaplan Meier modeling and Cox proportional hazards regression. Conclusions: Patient education, income, and social support were not associated with time to diagnosis or time to disease recurrence. This suggests additional patient, procedure, or disease-specific factors contribute to the observed variations in iSGS surgical outcomes.

ObjectiveThe objective of this study was to determine the prevalence of benign vocal fold lesions (BVFLs) in patients with chronic cough over a 1‐year period.Study DesignCase series with chart review.SettingTertiary academic medical center.Subjects and MethodsA retrospective cohort study of patients with chronic cough seen in our tertiary multidisciplinary cough clinic from 2016 to 2017 was conducted. Patient characteristics, presence of BVFLs by laryngoscopy, and Leicester Cough Questionnaire (LCQ) were recorded.ResultsA total of 419 patients were included (average age: 61 years), and 67% of patients were female. Ten percent of patients had BVFLs: granuloma (5%), leukoplakia (3%), nodules (2%), and polyps (1%). Median cough duration was 2.9 years (interquartile range [IQR], 0.7‐8.5); no significant difference in median cough duration was observed between patients with BVFLs and those with no lesions (2.6 vs 3.0 years, P =. 86). In total, 178 patients (42%) had available LCQ data: median score of 10.2 (IQR, 7.9‐13.9); no significant difference in median LCQ was observed between patients with BVFLs and those with no lesions (10.5 vs 10.1, P =. 54).ConclusionPrevalence of BVFLs in our cohort of patients with chronic cough was 10%, with posterior glottic lesions—granuloma—being the most common (5%). Prevalence of midmembranous lesions was as follows: vocal fold nodules (2%) and vocal fold polyps (1%). BVFLs were not associated with longer cough duration or more severe cough. We cannot determine a causative or noncausative relationship between BVFLs and chronic cough at this time due to lack of a control group.

Objectives/Hypothesis Idiopathic subglottic stenosis (iSGS) is a rare and potentially life‐threatening disease marked by recurrent and progressive airway obstruction frequently requiring repeated surgery to stabilize the airway. Unknown etiology and low disease prevalence have limited the ability to characterize the natural history of iSGS and resulted in variability in surgical management. It is uncertain how this variation relates to clinical outcomes. Study Design Medical record abstraction. Methods Utilizing an international, multi‐institutional collaborative, we collected retrospective data on patient characteristics, treatment, and clinical outcomes. We investigated variation between and within open and endoscopic treatment approaches and assessed therapeutic outcomes; specifically, disease recurrence and need for tracheostomy at last follow‐up. Results Strikingly, 479 iSGS patients across 10 participating centers were nearly exclusively female (98%, 95% confidence interval [CI], 96.1–99.6), Caucasian (95%, 95% CI, 92.2–98.8), and otherwise healthy (mean age‐adjusted Charlson Comorbidity Index 1.5; 95% CI, 1.44–1.69). The patients presented at a mean age of 50 years (95% CI, 48.8–51.1). A total of 80.2% were managed endoscopically, whereas 19.8% underwent open reconstruction. Endoscopic surgery had a significantly higher rate of disease recurrence than the open approach (chi 2 = 4.09, P = 0.043). Tracheostomy was avoided in 97% of patients irrespective of surgical approach (95% CI, 94.5–99.8). Interestingly, there were outliers in rates of disease recurrence between centers using similar treatment approaches. Conclusion Idiopathic subglottic stenosis patients are surprisingly homogeneous. The heterogeneity of treatment approaches and the observed outliers in disease recurrence rates between centers raises the potential for improved clinical outcomes through a detailed understanding of the processes of care.

OBJECTIVEThe goal was to examine the current scope of otolaryngologists’ practices, their geographic distribution, and the roles otolaryngologists and other specialists play in caring for patients with otolaryngic and related conditions of the head and neck.STUDY DESIGNA large national survey and administrative claims databases were examined to develop practice profiles and compile a physician supply for otolaryngology. A focus group of otolaryngologists provided information to model future scenarios.RESULTSThe current and predicted workforce supply and demographics are at a satisfactory level and are decreasing as a proportion of the increasing population. Empiric data analysis supports the diverse nature of an otolaryngologist's practice and the unique role for otolaryngologists that is not shared by many other providers. Together with the focus group results, the study points to areas for which more background and training are warranted.CONCLUSIONSThis study represents a first step in a process to form coherent workforce recommendations for the field of otolaryngology.
