Patient Use of Low-cost Digital Videoscopes and Smartphones for Remote Ear and Oropharyngeal Examinations.

Importance: During the novel coronavirus disease 2019 pandemic, telehealth has become a vital component of health care delivery. For otolaryngology evaluations, examination of the ear and oropharynx is important but difficult to achieve remotely. Objective: To assess the feasibility of patient use of low-cost digital videoscopes and smartphones for examination of the ear and oropharynx. Design, Setting, and Participants: A prospective quality improvement study was conducted in an academic adult otolaryngology clinic including 23 patients who presented for an in-person appointment and owned a smartphone device. The study was conducted from July 1 to 15, 2020. Interventions: Participants were asked to capture pictures and videos of their ear canals and oropharynx with digital videoscopes and their smartphones under real-time guidance over a telehealth platform. They were then surveyed about their experience. Main Outcomes and Measures: The primary outcomes were ratings by health care clinicians and a blinded otolaryngologist reviewer of image acceptability. Secondary outcomes included participant time to image acquisition and willingness to purchase digital videoscopes for telehealth use. Results: Of the 23 participants included, 14 were women (61%); mean age was 50 years (range, 21 to 80 years). Of the images obtained using the digital otoscope ear examination, 95% were considered acceptable by the health care clinicians and 91% were considered acceptable by the blinded reviewer; 16 participants (70%) reported that the otoscope was easy to use. The mean time to acquire images for both ears was 114 seconds (95% CI, 84-145 seconds). Twenty-one participants (91%) were willing to pay for a digital otoscope for telehealth use. For the oropharyngeal examination, a greater proportion of smartphone video examinations were considered acceptable by clinicians (63% acceptability) and the blinded reviewer (55%) compared with the digital endoscope (clinicians, 40%; blinded reviewer, 14%). The mean time required for the oropharyngeal examination smartphone video capture was shorter at 35 seconds compared with both the digital endoscope (difference, -27 seconds; 95% CI, -7 to -47 seconds) and smartphone photo capture (difference, -53 seconds; 95% CI, -20 to -87 seconds). Conclusions and Relevance: Digital otoscopes and smartphones apparently can facilitate remote head and neck physical examination in telehealth. Digital otoscopes were useful for ear examinations, and smartphone videos appeared to be the most useful for oropharyngeal examinations. Further studies are required to determine specific diagnostic capabilities in various telehealth practice settings.

Comprehensive Community Screening of Otological Patients by Trained Technicians Using a Telemedicine Device: An Efficient and Cost-Effective Way to Triage Patients With Ear Diseases.

OBJECTIVE: To emphasize the benefits of tele-otology in community screening of patients with ear diseases. METHODS: A retrospective study of all patients screened and treated under the Shruti tele-otology program between 2013 and 2019 was conducted. It involved screening, diagnosis, medical management, surgical intervention, and rehabilitation using hearing aid. The study focused on underprivileged and underserved community of rural and urban slums across 12 states of India. The study was conducted using a telemedicine device called ENTraview, that is, a camera-enabled android phone integrated with an otoscope and audiometry screening. RESULT: A total of 810 746 people were screened, and incidence of various ear diseases was recorded. Ear problems were found in 265 615 (33%) patients, of which 151 067 (57%) had impacted wax, 46 792(18%) had chronic suppurative otitis media, 27 875 (10%) had diminished hearing, 12 729 (5%) had acute otitis media and acute suppurative otitis media (ASOM), and 27 152 (10%) had problems of foreign body, otomycosis, and so on. Of the total 265 615 referred patients, 20 986 (8%) reported for treatment and received treatment at a significantly reduced cost through Shruti program partners. The conversion rate of nonsurgical and surgical procedure was also compared, and it was found that, while 9% of the patients opted for nonsurgical treatment, only 3% opted for surgery in the intervention group giving a significant P value of .00001. CONCLUSION: The potential for telemedicine to reduce inequalities in health care is immense but remains underutilized. Shruti has largely been able to bridge this gap as it is an innovative, fast, and effective programs that address the ear ailment in the community.

Financial Transactions from Manufacturers to Otolaryngologists in 2018.

OBJECTIVE: To characterize in depth non-research and research payments from industry to otolaryngologists in 2018 with an emphasis on product types. METHODS: Centers for Medicare and Medicaid Services Open Payments program was used for data collection: payment amount, the nature of payments, products associated with the payments, date of the payments, and companies making the payments were studied. Products associated with the payments were classified by categorical type. Descriptive statistics were used to analyze the data. RESULTS: There were 70,172 payments for a total of $11,001,875 made to otolaryngologists in 2018 with a median payment of $19. Food and beverage had the highest number of payments made (89.96%). Consulting fees (33.46%) composed the highest total payment amount. The two companies that contributed the highest amount were Stryker Corporation and Intersect ENT Inc. Sinus conditions had the most products within the top 25 products associated with payments. The top five products with the highest payments received were for balloon sinus dilation, nasal spray, sinus implant, Botox, and cochlear implant. There was a bimodal payment distribution demonstrating a higher number of payments made in the spring and fall. CONCLUSION: Our study is the first to review payments to otolaryngologists in 2018 and classify these payments into product types. The products and companies that contributed the highest payments were associated with sinus conditions. The products that dominated in each subspecialty of otolaryngology coincide with clinical practice trends and emerging technologies. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E388-E394, 2021.

Should I Buy This? A Decision-Making Tool for Surgical Value-Based Purchasing.

Many considerations affect the value that a new instrument or product may generate in a surgical practice. This review serves as a guide for surgeons considering new purchases and/or wishing to advocate for hospital acquisition of new items. A summary of data from academic and industry practices is presented, with pertinent examples using relevant surgical devices such as disposable devices, laparoscopic trocars, and otologic endoscopes. Surgeons considering incorporating a new instrument or technology within their practice should weigh the following factors before decision making: patient and clinical care factors, surgeon and care team factors, and hospital factors such as cost, revenue, and sourcing. A surgeon well-versed in stakeholder interests who is involved in the purchase of a new instrument may have significant influence in value-based decision making that not only affects his or her practice but ultimately maximizes value for the patient.

The cost of being clean: A cost analysis of nasopharyngoscope reprocessing techniques.

OBJECTIVE: Nasopharyngoscopes are an essential instrument to otolaryngologists; reprocessing them in a high-value manner is paramount. Although several different techniques for reprocessing exist, all methods yield similar effectiveness. Given equivalent effectiveness outcomes, a cost analysis of four nasopharyngoscope reprocessing techniques was performed. STUDY DESIGN: Cost-minimization analysis. METHODS: Four techniques were evaluated: 1) an automated reprocessor using peracetic acid (Steris System 1; Steris Canada Inc., Mississauga, Canada), 2) an automated reprocessor using ortho-phthalaldehyde (OPA) (Cidex OPA; Advanced Sterilization Products, Johnson and Johnson Inc., Markham, Canada), 3) a manually performed accelerated hydrogen peroxide bath (Revital-Ox; Steris Canada Inc.), and 4) a chlorine dioxide wipe (Tristel Trio Wipes System; Tristel plc, Cambridgeshire, U.K.). The costing perspective was a third-party payer that was adjusted to 2014 Canadian dollars. The base-case scenario used an annual volume of 4,153 reprocessing events in a tertiary care setting, and a scenario analysis assessed the impact of volume and capital expense. RESULTS: The cost per reprocessing event for the Steris (Steris Canada Inc.) automated endoscope reprocessing, Cidex OPA (Advanced Sterilization Products), Revital-Ox (Steris Canada Inc.), and Tristel Trio Wipes (Tristel plc) were $20.58, $14.20, $9.57, and $13.14, respectively. Scenario analysis demonstrated the Tristel Trio Wipes System (Tristel plc) was the least expensive method in practices with low reprocessing volumes (a threshold of less than 6 events per day, or 22 per week), whereas the Revital-Ox (Steris Canada Inc.) system was least expensive at higher volumes and became substantially more so as volumes increased. CONCLUSION: A manual accelerated hydrogen peroxide bath offers the least costly approach to nasopharyngoscope reprocessing. The convenience and portability of the Tristel Trio (Tristel plc) system may be a good alternative for low reprocessing volumes, or when rapid turnaround is necessary. LEVEL OF EVIDENCE: NA.

High-Level Disinfection of Otorhinolaryngology Clinical Instruments: An Evaluation of the Efficacy and Cost-effectiveness of Instrument Storage.

Objectives Despite increasing interest in individual instrument storage, risk of bacterial cross-contamination of otorhinolaryngology clinic instruments has not been assessed. This study is the first to determine the clinical efficacy and cost-effectiveness of standard high-level disinfection and clinic instrument storage. Methods To assess for cross-contamination, surveillance cultures of otorhinolaryngology clinic instruments subject to standard high-level disinfection and storage were obtained at the start and end of the outpatient clinical workday. Rate of microorganism recovery was compared with cultures of instruments stored in individual peel packs and control cultures of contaminated instruments. Based on historical clinic data, the direct allocation method of cost accounting was used to determine aggregate raw material cost and additional labor hours required to process and restock peel-packed instruments. Results Among 150 cultures of standard high-level disinfected and co-located clinic instruments, 3 positive bacterial cultures occurred; 100% of control cultures were positive for bacterial species ( P < .001). There was no statistical difference between surveillance cultures obtained before and after the clinic day. While there was also no significant difference in rate of contamination between peel-packed and co-located instruments, peel packing all instruments requires 6250 additional labor hours, and conservative analyses place the cost of individual semicritical instrument storage at $97,852.50 per year. Discussion With in vitro inoculation of >200 otorhinolaryngology clinic instruments, this study demonstrates that standard high-level disinfection and storage are equally efficacious to more time-consuming and expensive individual instrument storage protocols, such as peel packing, with regard to bacterial contamination. Implications for Practice Standard high-level disinfection and storage are equally effective to labor-intensive and costly individual instrument storage protocols.

Surgeon-estimated costs of common consumables in otolaryngology.

OBJECTIVES/HYPOTHESIS: The current fiscal climate demands increasing emphasis on curbing hospital expenses incurred from surgical procedures. Disposable instruments and consumables play a major role, but the end user (the surgeon) is often unaware of the cost of these materials. The objectives of our study were: 1) to assess knowledge of costs of disposable instruments and consumable products, and 2) to gauge interest in greater access to cost information and its potential to change practice. STUDY DESIGN: We used a cross-sectional survey study to meet our study's objectives. METHODS: A paper-based anonymous questionnaire was administered in the Department of Otolaryngology at McGill University and at Western University asking for estimations of costs of 23 commonly used products in the operating room. Our primary outcome measure was accuracy of cost estimations, which were considered accurate if within ± 50% of the true cost at the respective institution. RESULTS: The average accuracy was 29.9% (standard deviation = 16.7%). There was no significant difference between residents (32.5%, 95% confidence interval [CI]: 10.2%-54.7%) and staff (28.3%, 95% CI: 11.0%-45.6%). Less than 10% of participants were able to accurately estimate the costs of at least half of the disposable products. The majority of participants (82%) felt that greater information would change their use of consumables. CONCLUSIONS: Surgical residents and staff have a generally poor knowledge of the cost of common consumable products used in the operating room. There is potential for increased awareness of costs to change behavior. LEVEL OF EVIDENCE: NA.

Validated assessment tools for pediatric airway endoscopy simulation.

OBJECTIVE: To determine the interrater reliability and construct validity of 3 separate assessment tools for assessing trainee skills in pediatric airway endoscopy simulation. DESIGN: An Objective Structured Assessment of Technical Skills (OSATS) was developed in which examinees were asked to name and assemble the airway foreign body instruments and retrieve a foreign body from an infant airway mannequin. Each examinee's performance was assessed in a blinded fashion by 3 pediatric otolaryngology faculty at separate residency programs using 3 assessment tools: (1) objective quantifiable measures list (eg, assists needed, forceps openings, foreign body drops), (2) 15-point OSATS checklist, and (3) Global Rating Index for Technical Skills (GRITS). Setting Otolaryngology residency program. Subjects Examinees (medical students, n = 3; otolaryngology residents, n = 17; pediatric otolaryngology faculty, n = 3) and raters (n = 3). Main Outcome Measures Interrater reliability and construct validity. Results Anonymized split-screen videos simultaneously capturing each examinee's instrument handling and the endoscopic videos were created for all 23 examinees. Nineteen videos were chosen for review by 3 raters. The interrater reliability as measured by the intraclass correlation for objective quantifiable measures ranged from 0.46 to 0.98. The intraclass correlation coefficient was 0.95 for the 15-point OSATS checklist and 0.95 for the GRITS; both showed a high degree of construct validity with scores correlating with previous experience. Conclusion Assessment tools for skills assessments must have high interrater reliability and construct validity. When assessing trainee skills in pediatric airway foreign body scenarios, the 15-point OSATS checklist developed by this group or the GRITS meets these criteria.

Dr. Otto "Tiger" Freer: inventor and innovator.

Every neurosurgeon develops his or her own standard approach to common intracranial pathologies in terms of the order in which different stages are performed and which instruments are used to perform individual tasks. The majority of the basic steps in performing a craniotomy are learned through repetition and practice during residency training. Significant amounts of energy are devoted to mastering technical skills and developing an operative rhythm. What often receives little attention is the historical origin of the instruments that make the work possible. The Freer elevator represents a particularly interesting example. To people unfamiliar with the accomplishments of turn-of-the-century laryngologist Otto "Tiger" Freer, it can be assumed that the name of the instrument in one's hand is simply named for what it can do, that is, to "free" the nasal mucosa from the bony and cartilaginous septum during the transsphenoidal approach. The technique this master surgeon spent his life and career perfecting is now repeated almost daily by skull base neurosurgeons approaching pathologies from the inferior frontal lobe to the foramen magnum. In reviewing his life and work, the authors of this paper discovered an interesting creative process that led to the design of the eponymous instrument. Additionally, they discovered important advances toward the development of the transnasal approach and in our understanding of the anterior skull base. They present a historical perspective on the life and accomplishments of Dr. Freer and the ubiquitous surgical instrument that he invented and popularized.

[Use of a rigid laryngoscope and a flexible nasal fiberoptic scope to assess the difficult airway: description of 3 cases]. / Utilización del laringoscopio rígido y el nasofibroscopio flexible en la valoración de la vía aérea difícil: descripción de 3 casos.

Indirect inspection of the airway using a 70 degrees rigid laryngoscope plus a flexible nasal fiberoptic scope can provide additional information when the anesthesiologist foresees that airway management will be difficult. These devices are useful for detecting structural abnormalities, they can be attached to the same visualization system, and they do not require topical anesthesia or sedation of the patient. We report on 3 patients diagnosed with difficult airway. Inspection with a rigid laryngoscope during the preanesthetic assessment visit revealed abnormalities that prevented visualization of the glottis. In the first case, the epiglottis was absent, as it had been removed with a surrounding tumor; in the second and third cases, an epiglottic deformity and hypertrophy of the base of the tongue were found. A flexible nasal fiberoptic scope gave an unobstructed view of the glottis in these cases, making it easier to choose an intubation method.

Telemedicine-assisted neurotology in post-Katrina Southeast Louisiana.

OBJECTIVE: This study evaluates technical requirements, privacy and legal constraints, reimbursement considerations, and overall feasibility of a new telemedicine neurotologic patient care delivery model in post-Katrina, Southeast Louisiana. METHODS: This study is a retrospective review of the first year of a telemedicine neurotology practice with limited on-site neurotology physician availability (3-days monthly) with a full-time on-site audiologist, a full-time specialty-trained nurse practitioner, full-time neurosurgery on-site availability, and full-time otolaryngology on-site availability. RESULTS: A combined "store-and-forward" and "real-time" telemedicine delivery model was implemented for a new neurotology practice. Technical requirements include secure data transfer, real-time video-streaming, high-quality video otoscopy and microscopy, infrared video eye movement visualization and recording, remote visualization of radiologic imaging studies, and formalized diagnostic algorithms for patient evaluation. Telemedicine patient evaluations occur with the patient in Baton Rouge, LA, while the examining neurotologist is linked through a secure, commercially available communication connection in Pittsburgh, PA. Specifically designed consent forms and bilocation licensing and liability insurance coverage were required. Third-party payers were consulted before implementation to assure adherence to local reimbursement requirements. During the first 12 months of operation, 450 patient encounters were accomplished purely through telemedicine, with an additional 800 on-site patient visits and 150 operative procedures, including 24 neurotologic skull base procedures. CONCLUSION: Telemedicine is a viable delivery model for neurotology care delivery. Planning and implementation of such a model requires systematic considerations of medical, nursing, information systems, legal, reimbursement, and management parameters. Although the authors' initial motivation for this model was the resource-restricted, post-Katrina health care environment in South Louisiana, this delivery model has wider applicability in otolaryngology, other medical specialties, humanitarian outreach, and medical education. Prospective assessment of clinical outcomes and patient satisfaction is ongoing for objective validation of this delivery model.

A low-cost, endoscopic, digital, still and video photography system for ENT clinics.

Image capture systems that display and record endoscopic images are important for documentation and teaching. We have modified a universal serial bus microscope to couple with most clinical endoscopes used in our practice. This very economical device produces images suitable for teaching, and potentially for clinical use. The implications of this could be significant for teaching, patient education, documentation and the developing world.

Microbiologic assessment of disposable sterile endoscopic sheaths to replace high-level disinfection in reprocessing: a prospective clinical trial with nasopharygoscopes.

BACKGROUND: Conventional reprocessing of endoscopes with high-level disinfection is labor intensive, expensive, delays the turnover of instruments, and involves potential exposure of personnel to toxic chemicals. We report a prospective clinical trial with rigorous microbiologic assessment of a novel disposable, sterile, polyurethane sheath, which can be easily and snugly applied over a nasopharyngoscope before performing the endoscopic procedure, with enzymatic cleansing and disinfection of the instrument with 70% ethanol following the procedure to determine whether the use of the novel sheath can provide reliable protection against bacterial contamination and obviate the need for routine high-level disinfection in reprocessing. METHODS: Baseline cultures were obtained at 3 time periods from the control heads and insertion shafts of nasopharyngoscopes used in 100 clinical examinations: before application of the protective sheath and execution of the procedure; immediately after the procedure and removal of the sheath; and after enzymatic cleaning, disinfection with 70% ethanol, and drying. All 100 used sheaths and 20 unused sheaths were subjected to high-pressure leak testing to assess barrier integrity. RESULTS: Bacteria were detected on 16 control heads and 6 shafts prior to the procedure; from 13 heads and 1 shaft immediately following the nasopharyngoscopic procedure and sterile sheath removal; and none of the instruments following cleaning, ethanol disinfection, and drying. No sheath showed loss of barrier integrity on leak testing. CONCLUSION: Use of a high-quality, snugly fitting, sterile, disposable polyurethane sheath on a nasopharyngoscope during a clinical examination, combined with enzymatic detergent cleaning and disinfection with 70% ethanol, can provide a reliably decontaminated, patient-ready instrument, eliminating the need for high-level disinfection of endoscopes.
