COVID-19 and the resurgence of telehealth in otolaryngology

Diagnostic accuracy and management concordance of otorhinolaryngological diseases through telehealth or remote visits: A systematic review & meta-analysis

INTRODUCTION

COVID-19 has led to delays in providing healthcare in both emergency and non-emergency settings, especially in surgical subspecialties which rely heavily on referrals and in-person visits. Without an established telehealth infrastructure, many otorhinolaryngological departments experienced decreases in consultations. Telemedicine has attempted to bridge the gap between pre- and post-pandemic periods by creating a safe avenue of communication between otorhinolaryngologists and patients. This review hopes to address the accuracy of telemedicine in patient diagnosis and management.

METHODS

Searches were conducted since study conception until June 30, 2022, on multiple databases including PubMed, SCOPUS, and CINAHL for this systematic review and meta-analysis. Diagnostic accuracy, management accuracy, kappa, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were meta-analyzed by comparing virtual visits to in-person visits (gold standard).

RESULTS

Nineteen studies were included in this review. A total of 1518 patients were included across all studies. When comparing virtual visits against in-person visits, accurate diagnosis was made in 86.2% [82.1,89.9, I2 = 73.5%, P < 0.0001] of patients and management accuracy was 91.5% [86.1,95.7, I2 = 81.8%, P < 0.0001] when treating patients. Kappa value determining interrater reliability was 0.8 [0.7,0.9, I2 = 81.8%, P < 0.0001].

CONCLUSION

Our data suggest that diagnostic and management concordance is above 80% when comparing diagnosis and management strategies in patients who underwent both telehealth and in-person visits with an otorhinolaryngologist. In uncomplicated patients, telehealth might be a reliable source for diagnosis and management however, in-person consultation is likely still required for pathologies in which physical exam, imaging or procedural elements represent a vital component of the work-up.

Video Otoscopy as a Novel Teaching and Remote Otolaryngology Consultation Tool at an Academic Medical Center

OBJECTIVE

Assess the use of video otoscopy (VO) as a tool for teaching Emergency Department (ED) residents and remote Otolaryngology consultation.

STUDY DESIGN

Survey and retrospective chart review.

SETTING

Tertiary care center.

METHODS

Emergency Medicine resident physicians completed an otologic skill self-assessment and pathology followed by an interactive training on VO and postintervention assessment after 9 months of use. Outcomes compared change in pre- to posttraining scores. ED consultations using VO during this time period were reviewed to detect differences between the presumed diagnosis/treatment based only on phone consultation and VO image compared to the final diagnosis/treatment after in-person Otolaryngology consultation.

RESULTS

Forty-six (63.1%) ED residents participated. Diagnostic accuracy improved by 20.7% overall. The most improved diagnoses were of a normal ear canal (+75%), tympanosclerosis (+58.4%), and ear canal foreign body (+57.1%); most challenging were external auditory canal cyst (-13.6%), hemotympanum (-11.3%), and cerumen (-1.9%). Cholesteatoma did not improve because all responses were incorrect; neither did tympanic membrane perforation because all were correct. Confidence in the otologic exam and anatomy also increased (P < .01). Thirteen consults used VO and 3 (23.1%) had a change in diagnosis/treatment after in-person Otolaryngology evaluation.

CONCLUSION

Training on the use of VO significantly improves the confidence and diagnostic skills of ED providers for many pathologies. This application suggests the efficacy of an otologic e-consultation model.

Telehealth Usage in Otolaryngology: A Comparative Study Pre- and Post-COVID-19

The COVID-19 pandemic led to increased telehealth utilization in outpatient otolaryngology settings. While other studies on telehealth usage in otolaryngology settings have focused on demographic disparities during the pandemic, none have yet assessed how these demographic disparities have evolved from before versus after the pandemic. This study examines 4 recent consecutive years of demographic and clinical data from a large hospital system to investigate how the COVID-19 pandemic has changed demographic patterns in telehealth utilization. We demonstrate substantial increases in the number of otolaryngology patients participating in telehealth since the beginning of the COVID-19 pandemic but with no differences in patient distributions by race or ethnicity over time. We also found that telehealth patients, on average, were younger, more likely to be English-speaking, and more likely to be female. While these disparities widened slightly after the start of the pandemic, they were also present prior to the pandemic.

Examining Use and Effectiveness of Teletherapy for Patients with Dysphonia

OBJECTIVE(S)/HYPOTHESIS

Virtual therapy (teletherapy) for patients with dysphonia has become ubiquitous in the COVID-19 era. However, barriers to widespread implementation are evident, including unpredictable insurance coverage attributed to limited evidence supporting this approach. In our single-institution cohort, our objective was to show strong evidence for use and effectiveness of teletherapy for patients with dysphonia.

STUDY DESIGN

Single institution, retrospective cohort study.

MATERIAL AND METHODS

This was an analysis of all patients referred for speech therapy with dysphonia as primary diagnosis from 4/1/2020 to 7/1/2021 and in whom all therapy sessions were delivered in a teletherapy format. We collated and analyzed demographics and clinical characteristics and adherence to the teletherapy program. We assessed changes in perceptual assessments and vocal capabilities (GRBAS, MPT), patient-reported outcomes (V-RQOL), and metrics of session outcomes (complexity of vocal tasks, carry-over of target voice) pre- and post-teletherapy using student's t test and chi-square test.

RESULTS

Our cohort included 234 patients (mean [SD] age 52 [20] years) residing a mean (SD) distance of 51.3 (67.1) miles from our institution. The most common referral diagnosis was muscle tension dysphonia (n = 145, 62.0% patients). Patients attended a mean (SD) of 4.2 (3.0) sessions; 68.0% (n = 159) of patients completed four or more sessions and/or were deemed appropriate for discharge from teletherapy program. Statistically significant improvements were seen in complexity and consistency of vocal tasks with consistent gains in carry-over of target voice for isolated tasks and connected speech.

CONCLUSIONS

Teletherapy is a versatile and effective approach for treatment of patients with dysphonia of varying age, geography, and diagnoses.
