Purpose: Diagnosing pediatric induced laryngeal obstruction (ILO) requires equipment typically available in specialist settings, and patients often see multiple providers before a diagnosis is determined. This study examined the financial burden associated with the diagnosis and treatment of ILO in pediatric patients with reference to socioeconomic disadvantage. Methods: Adolescents and children (<18 years of age) diagnosed with ILO were identified through the University of Madison Voice and Swallow Outcomes Database. Procedures, office visits, and prescribed medications were collected from the electronic medical record. Expenditures were calculated for two time periods (1) pre‐diagnosis (first dyspnea‐related visit to diagnosis), and (2) the first year following diagnosis. The Area Deprivation Index (ADI) was used to estimate patient socioeconomic status to determine if costs differed with neighborhood‐level disadvantage. Results: A total of 113 patients met inclusion criteria (13.9 years, 79% female). Total pre‐diagnosis costs of ILO averaged $6486.93 (SD = $6604.14, median = $3845.66) and post‐diagnosis costs averaged $2067.69 (SD = $2322.78; median = $1384.12). Patients underwent a mean of 3.01 (SD = 1.9; median = 2) procedures and 5.8 (SD = 4.7; median = 5) office visits prior to diagnosis. Pharmaceutical, procedure/office visit, and indirect costs significantly decreased following diagnosis. Patients living in neighborhoods with greater socioeconomic disadvantage underwent fewer procedures and were prescribed more medication than those from more affluent areas. However, total expenditures did not differ based on ADI. Conclusions: Pediatric ILO is associated with considerable financial costs. The source of these costs, however, differed according to socioeconomic advantage. Future work should determine how ILO diagnosis and management can be more efficient and equitable across all patients. Laryngoscope, 134:3384–3390, 2024 [ABSTRACT FROM AUTHOR]

Objectives: A small number of Idiopathic subglottic stenosis (iSGS) patients are treated at institutions across the country. Divergence in operative techniques for endoscopic dilation (ED) of iSGS has been anecdotally recognized but not formally characterized. Additionally, the relationship between procedural variation and clinical outcome has not been studied. Methods: Secondary analysis of the NoAAC iSGS1000 cohort investigated variation in procedural techniques and treatment outcomes in patients treated with ED across high‐enrolling treatment centers (enrolled >10 patients in PR‐02 trial). Results: Thirteen NoAAC centers each enrolled >10 patients treated with ED for a total of 281 subjects. There was significant variation in procedural details and rate of recurrence among institutions. Hierarchal cluster analysis revealed significant heterogeneity among institutions and clusters in all procedural variables. However, analysis demonstrated a transient delay in disease recurrence in cluster 2 which disappeared with longer longitudinal follow‐up. Patient‐reported outcome and peak expiratory flow data supported the potential benefit of the technical variation in Cluster 2. Distinct to cluster 2, however, was routine use of adjuvant triple medical therapy (proton pump inhibitor (PPI), antibacterial agent, and steroid inhaler). Conclusions: Both outcome and procedural technique vary among centers employing ED to treat iSGS. A transient delay in recurrence was observed among centers that routinely prescribed adjuvant medical therapy (antibiotic, inhaled corticosteroid, and PPI) to iSGS patients after endoscopic dilation, which was further supported by patient‐reported data and peak expiratory flow data. Prospective studies are needed to understand the effects of adjuvant medical therapy on recurrence after endoscopic dilation.

Objective: Idiopathic subglottic stenosis (iSGS) is a rare, recurrent, fibroinflammatory disease affecting the larynx and proximal trachea. Given it occurs primarily in adult females, estrogen is speculated to play a central pathophysiological role. This study aimed to evaluate relationships between estrogen exposure, disease progression, and recurrence. Methods: North American Airway Collaborative (NoAAC) data of adults with iSGS obstructive airway lesions, who underwent index endoscopic airway dilation, were used to identify associations between estrogen exposure, disease characteristics, and time to recurrence (TTR), and interventions were analyzed using Kruskal–Wallis test and Pearson coefficient. Cox proportional hazards regression models compared hazard ratios by estrogen exposure. Kaplan–Meier curves were plotted for TTR based on menopausal status. Results: In all, 533 females had complete estrogen data (33% premenopausal, 17% perimenopausal, 50% postmenopausal). Median estrogen exposure was 28 years. Overall, there was no dose–response relationship between estrogen exposure and disease recurrence. Premenopausal patients had significantly shorter time from symptom manifestation to diagnosis (1.17 vs. 1.42 years perimenopausal vs. 2.08 years postmenopausal, p < 0.001), shorter time from diagnosis to index endoscopic airway dilation (1.90 vs. 2.50 vs. 3.76 years, p = 0.005), and higher number of procedures (1.73 vs. 1.20 vs. 1.08 procedures, p < 0.001). Conclusions: We demonstrate premenopausal patients may have a more aggressive disease variant than their peri‐ and postmenopausal counterparts. However, it is unclear as to whether this is related to reduced estrogen in the peri‐ and postmenopausal states or the age‐related physiology of wound healing and inflammation, regardless of estrogen.

Objective: Idiopathic subglottic stenosis is a rare disease, and time to diagnosis is often prolonged. In the United States, some estimate it takes an average of 9 years for patients with similar rare disease to be diagnosed. Patient experience during this period is termed the diagnostic odyssey. The aim of this study is to use qualitative methods grounded in behavioral‐ecological conceptual frameworks to identify drivers of diagnostic odyssey length that can help inform efforts to improve health care for iSGS patients. Methods: Qualitative study using semi‐structured interviews. Setting consisted of participants who were recruited from those enrolled in a large, prospective multicenter trial. We use directed content analysis to analyze qualitative semi‐structured interviews with iSGS patients focusing on their pathways to diagnosis. Results: Overall, 30 patients with iSGS underwent semi‐structured interviews. The patient‐reported median time to diagnosis was 21 months. On average, the participants visited four different health care providers. Specialists were most likely to make an appropriate referral to otolaryngology that ended in diagnosis. However, when primary care providers referred to otolaryngology, patients experienced a shorter diagnostic odyssey. The most important behavioral‐ecological factors in accelerating diagnosis were strong social support for the patient and providers' willingness to refer. Conclusion: Several factors affected time to diagnosis for iSGS patients. Patient social capital was a catalyst in decreasing time to diagnosis. Patient‐reported medical paternalism and gatekeeping limited specialty care referrals extended diagnostic odysseys. Additional research is needed to understand the effect of patient–provider and provider–provider relationships on time to diagnosis for patients with iSGS.

Purpose: The purpose of this study was to perform a comprehensive systematic review of the literature on voice-related patient-reported outcome (PRO) measures in adults and to evaluate each instrument for the presence of important measurement properties. Method: MEDLINE, the Cumulative Index of Nursing and Allied Health Literature, and the Health and Psychosocial Instrument databases were searched using relevant vocabulary terms and key terms related to PRO measures and voice. Inclusion and exclusion criteria were developed in consultation with an expert panel. Three independent investigators assessed study methodology using criteria developed a priori. Measurement properties were examined and entered into evidence tables. Results: A total of 3,744 studies assessing voice-related constructs were identified. This list was narrowed to 32 PRO measures on the basis of predetermined inclusion and exclusion criteria. Questionnaire measurement properties varied widely. Important thematic deficiencies were apparent: (a) lack of patient involvement in the item development process, (b) lack of robust construct validity, and (c) lack of clear interpretability and scaling. Conclusions: PRO measures are a principal means of evaluating treatment effectiveness in voice-related conditions. Despite their prominence, available PRO measures have disparate methodological rigor. Care must be taken to understand the psychometric and measurement properties and the applicability of PRO measures before advocating for their use in clinical or research applications.

Objectives: Serial intralesional steroid injection (SILSI) has been increasingly used to treat idiopathic subglottic stenosis (iSGS). Prior studies have shown effectiveness, but not in all patients. This multi‐institutional study evaluates the effect of SILSI on time to recurrent operation, peak expiratory flow (PEF), and dyspnea. Methods: Post‐hoc secondary analysis of the North American Airway Collaborative data were performed to evaluate the outcomes of iSGS patients undergoing and not undergoing SILSI. The primary outcome was time to recurrent operation, evaluated using Kaplan–Meier curves and Cox regression analysis. Secondary outcomes were change in PEF and clinical chronic obstructive pulmonary disease questionnaire (CCQ) score. Within patients undergoing SILSI, demographics, time from last procedure, and PEF at initiation of SILSI were evaluated to determine the effect on recurrence. Results: Two hundred and ninety patients were included, 238 undergoing endoscopic dilation alone and 52 undergoing dilation and SILSI. No differences in baseline characteristics were observed. There was no difference in time to recurrence (hazard ratio: 0.64; p = 0.183). There were no differences in PEF or CCQ across the 2.5‐year study period. Among 52 patients undergoing SILSI, PEF at the time of starting SILSI did not affect recurrence (χ2 = 0.09, p = 0.77). Conclusion: Patients undergoing and not undergoing SILSI had similar times to recurrence, PEF, and CCQ. Factors predicting recurrence among patients undergoing SILSI were not identified. These results support a randomized controlled trial with a uniform SILSI protocol to quantify the effects of SILSI on objective and subjective outcomes and help determine which iSGS patients benefit most.
