Sociodemographic Disparities in Tracheostomy Timing and Outcomes.

OBJECTIVE: Tracheostomies are commonly performed in critically ill patients requiring prolonged mechanical ventilation. Although early tracheostomy has been associated with improved outcomes, the reasons for delayed tracheostomy are complex. We examined the impact of sociodemographic factors on tracheostomy timing and outcomes. METHODS: Medical records were retrospectively reviewed of ventilator-dependent adult patients who underwent tracheostomy from 2021 to 2022. Tracheostomy timing was defined as routine (<21 days) versus late (21 days or more). Sociodemographic variables were compared between cohorts using univariate and multivariate models. Secondary outcomes included hospital length of stay (LOS), decannulation, tracheostomy-related complications, and inhospital mortality. RESULTS: One hundred forty-two patients underwent tracheostomy after initial intubation: 74.7% routine (n = 106) and 25.4% late (n = 36). In a multivariate model adjusted for age, race, surgical service, tracheostomy technique, and time between consultation and surgery, non-English speaking patients and women were more likely to receive a late tracheostomy compared with English speaking patients and men, respectively (odds ratio [OR] 3.18, 95% confidence interval [CI] 1.03, 9.81, p < 0.05), (OR 3.15, 95% CI 1.18, 8.41, p < 0.05). Late tracheostomy was associated with longer median hospital LOS (62 vs. 52 days, p < 0.05). Tracheostomy timing did not significantly impact mortality, decannulation or tracheostomy-related complications. CONCLUSION: Despite an association between earlier tracheostomy and shorter LOS, non-English speaking patients and female patients are more likely to receive a late tracheostomy. Standardized protocols for tracheostomy timing may address bias in the referral and execution of tracheostomy and reduce unnecessary hospital days.

Quantification of Vocal Fold Atrophy in Age-Related and Parkinson's Disease-Related Vocal Atrophy.

OBJECTIVE: Vocal fold atrophy (VFA) is associated with aging and Parkinson's disease (PD). Clinical diagnosis of VFA depends on several visual-perceptual laryngostroboscopy findings that are inherently subjective. The purpose of this study was to use quantitative measurements to; (1) examine the relationships between VFA and dysphonia severity and (2) evaluate differences in VFA in patients with age-related VFA versus PD. METHODS: Thirty-six patients >60 years of age with VFA were included in this retrospective cohort study. Demographic information, medical history, Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V), Voice Handicap Index-10 (VHI-10), and still images from the stroboscopic exam were obtained. Image J™ was used to measure VFA, including bowing index (BI), normalized glottal gap area, and normalized mucosal wave amplitude. Pearson's correlation was used to evaluate the relationship between VFA, CAPE-V, and VHI-10. t-Tests and multivariate linear regression were used to compare VFA measures by dysphonia severity (CAPE-V <30 vs. >30) and diagnosis (age-related vocal atrophy [ARVA] and PD). RESULTS: BI was positively correlated with CAPE-V. Patients with CAPE-V >30 had a significantly larger BI compared to those with CAPE-V <30. Patients with PD had significantly larger BI than those with ARVA. Diagnosis of PD also predicted a larger BI after controlling for age and CAPE-V. CONCLUSION: Quantitative measures supported an association between bowing severity and dysphonia severity in patients with PD and ARVA. A PD diagnosis significantly predicted more severe BI. These findings demonstrate the potential utility of BI. Quantitative VFA measures might also provide insight into the mechanisms of ARVA and dysphonia.

Pilot testing of a novel surgical simulator for endoscopic zenker's diverticulotomy.

OBJECTIVES/HYPOTHESIS: Restrictions on resident work hours and the increasing purview of otolaryngology reduce the efficacy of the traditional surgical training model. With limited case volumes at many institutions and the unique instrumentation of endoscopic Zenker's diverticulotomy (EZD), simulation may be useful to improve training. In this study, a novel surgical simulator for EZD is developed and validated. STUDY DESIGN: Simulation model development. METHODS: An EZD model was designed using an intubation trainer and disposable diverticulum inserts. A novel objective structured assessment of technical skill (OSATS) for EZD was developed. Performance of otolaryngology residents on simulations using the OSATS and time to completion were evaluated during an instructional course. Pre- and postencounter surveys were completed. Inter-rater and intrarater reliability were evaluated via blinded video review of resident performance. RESULTS: Seventeen residents participated (n = 17). Surveys showed confidence improved two points on a five-point scale (P < .001), and 94% agreed that the model would improve resident performance with in vivo EZD. More experienced trainees (postgraduate year [PGY] 3-5, n = 11 vs. PGY 1-2, n = 6) had shorter times to completion (P < .001) and higher assessment scores on initial attempts (P = .006). Both groups showed significant improvements from initial to final attempts on 30-point scales for global rating by 6.2 ± 4.2 (mean ± standard deviation, P < .001). The novel OSATS demonstrated fair live/video reliability (к = 0.40) and inter-rater reliability (к = 0.44), and moderate intrarater reliability (к = 0.60). CONCLUSIONS: Pilot testing of an EZD simulator demonstrated acceptability, content validity, and construct validity. A novel OSATS was developed and evaluated. Further investigation of the impact on operative performance and validation of the OSATS in vivo is needed. LEVEL OF EVIDENCE: NA Laryngoscope, 127:592-596, 2017.
