Impact of Masks on Speech Recognition in Adult Patients with and without Hearing Loss.

INTRODUCTION: The coronavirus 2019 pandemic has altered how modern healthcare is delivered to patients. Concerns have been raised that masks may hinder effective communication, particularly in patients with hearing loss. The purpose of this study is to determine the effect of masks on speech recognition in adult patients with and without self-reported hearing loss in a clinical setting. METHODS: Adult patients presenting to an otolaryngology clinic were recruited. A digital recording of 36 spondaic words was presented to each participant in a standard clinical exam room. Each word was recorded in 1 of 3 conditions: no mask, surgical mask, or N95 mask. Participants were instructed to repeat back the word. The word recognition score was determined by the percent correctly repeated. RESULTS: A total of 45 participants were included in this study. Overall, the mean word recognition score was 87% without a mask, 78% with a surgical mask, and 61% with an N95 mask. Among the 23 subjects (51.1%) with self-reported hearing loss, the average word recognition score was 46% with an N95 mask compared to 79% in patients who reported normal hearing (p < 0.001). CONCLUSION: Our results suggest that masks significantly decrease word recognition, and this effect is exacerbated with N95 masks, particularly in patients with hearing loss. As masks are essential to allow for safe patient-physician interactions, it is imperative that clinicians are aware they may create a barrier to effective communication.

In Vivo Fluticasone Absorption in Surgical Patients.

BACKGROUND: Intranasal corticosteroids (INCS) are a treatment mainstay of chronic rhinosinusitis and allergic rhinitis. Current computational models demonstrate that >90% of INCS drug deposition occurs on the head of the inferior turbinate and nasal valve, rather than the actual sinuses. These models do not consider mucociliary clearance which propels mucus posteriorly, nor do they consider the absorption of the drug. The purpose of this study is to better understand the exact anatomical location where INCS are absorbed. METHODS: Patients with chronic rhinosinusitis and allergic rhinitis taking fluticasone pre-operatively who were scheduled for functional endoscopic sinus surgery and inferior turbinate reduction, respectively, were recruited. Intra-operative tissue samples were obtained from predetermined locations within the sinonasal cavity. Mass spectrometry was then used to quantify the amount of absorption in each specific anatomic location to determine the largest amount of absorption. RESULTS: Eighteen patients were included in our study. The greatest fluticasone absorption levels across the sinonasal anatomy were at the anterior inferior turbinate (5.7 ngl/mL), ethmoid sinus, (4.4 ng/mL), posterior inferior turbinate (3.7 ng/mL), maxillary sinus (1.3 ng/mL), and the sphenoethmoidal recess (0.72 ng/mL) respectively. Absorption was significantly higher in revision surgery compared to surgically naïve patients. CONCLUSIONS: Computation fluid dynamic models of the nasal passage are useful models to help predict intranasal particle flow. However, these models do not incorporate or consider the important mucociliary clearance system, leading to absorption of fluticasone throughout the sinonasal cavity far beyond that predicted by these models.

Quantifying the Magnitude and Longevity of the Effect of Repetitive Head Impacts in Adolescent Soccer Players: Deleterious Effect of Long Headers Extend Beyond a Month.

There is growing interest in the effects of sports-related repetitive head impacts (RHIs) on athletes' cognitive capabilities. This study examines the effect of RHIs in data collected from adolescent athletes to estimate the magnitude and longevity of RHIs on sensorimotor and cognitive performance. A non-linear regression model estimated the longevity of RHI effects by adding a half-life parameter embedded in an exponential decay function. A model estimate of this parameter allows the possibility of RHI effects to attenuate over time and introduces a mechanism to study the cumulative effect of RHIs. The posterior distribution of the half-life parameter associated with short-distance headers (<30 m) is centered around 6 days, whereas the posterior distribution of the half-life parameter associated with long-distance headers extends beyond a month. Additionally, the magnitude of the effect of each short header is around 3 times smaller than that of a long header. The results indicate that, on both tasks, response time (RT) changes after long headers are bigger in magnitude and last longer compared to the effects of short headers. Most important, we demonstrate that deleterious effects of long headers extend beyond 1 month. Although estimates are based on data from a relatively short-duration study with a relatively small sample size, the proposed model provides a mechanism to estimate long-term behavioral slowing from RHIs, which may be helpful to reduce the risk of additional injury. Finally, differences in the longevity of the effects of short and long RHIs may help to explain the large variance found between biomechanical input and clinical outcome in studies of concussion tolerance.

Remote Video Auditing in the Surgical Setting.

Remote video auditing, a method first adopted by the food preparation industry, was later introduced to the health care industry as a novel approach to improving hand hygiene practices. This strategy yielded tremendous and sustained improvement, causing leaders to consider the potential effects of such technology on the complex surgical environment. This article outlines the implementation of remote video auditing and the first year of activity, outcomes, and measurable successes in a busy surgery department in the eastern United States. A team of anesthesia care providers, surgeons, and OR personnel used low-resolution cameras, large-screen displays, and cell phone alerts to make significant progress in three domains: application of the Universal Protocol for preventing wrong site, wrong procedure, wrong person surgery; efficiency metrics; and cleaning compliance. The use of cameras with real-time auditing and results-sharing created an environment of continuous learning, compliance, and synergy, which has resulted in a safer, cleaner, and more efficient OR.
