Trends in Otolaryngology Consultation Patterns at an Academic Quaternary Care Center

Factors Associated With Head and Neck Polytrauma Presentation and Admissions at Emergency Departments of Varying Sizes

Timely diagnosis of acute head and neck polytrauma presenting to emergency departments (EDs) optimizes outcomes. Since ED capacity influences triage and admission, the authors utilized the National Electronic Injury Surveillance System database to understand how ED size and trauma characteristics affect head and neck polytrauma presentation and admissions. Demographics and injury characteristics from the National Electronic Injury Surveillance System database from 2018 to 2021 were analyzed to delineate factors contributing to polytrauma presence and admission through multivariable logistic regressions. The authors' 207,951-patient cohort was primarily females (48.6%), non-Hispanic (62.4%), and white (51.4%) people who averaged 57.2 years old. Nonspecific head injuries were predominant (59.7%), followed by facial trauma (22.6%) with rare substance involvement (alcohol, 6.3%; drugs, 4.1%) presenting to high-volume EDs (48.5%). Of the patients, 20% were admitted, whereas 31.1% sustained polytrauma. Substance use [alcohol, odds ratio (OR) = 4.44; drugs, OR = 2.90] increased polytrauma likelihood; neck (OR = 1.35), face (OR = 1.14), and eye (OR = 1.26) associated with polytrauma more than head injuries. Burns (OR = 1.38) increased polytrauma likelihood more than internal organ injuries. Black patients sustained higher polytrauma when presented to non-small EDs (OR = 1.41-1.90) than white patients showed to small EDs. Admissions were higher for males (OR = 1.51). Relative to small EDs, large EDs demonstrated a higher increase in admissions (OR = 2.42). Neck traumas were more likely admitted than head traumas (OR = 1.71). Fractures (OR = 2.21) and burns (OR = 2.71) demonstrated an increased admission likelihood than internal organ injuries. Polytrauma presence and admissions likelihood are site, injury, and substance dependent. Understanding the impact of factors influencing polytrauma presence or admission will enhance triage to optimize outcomes.

An Integrative Model of ENT Healthcare for the Homeless Population

OBJECTIVE

Our aim was to determine the need for otolaryngology care within the homeless population, identify barriers to access that the homeless population may face, and develop a model system which would address these needs with respect to the barriers.

METHODS

A retrospective chart review of 812 patients seen between 1/25/16-3/21/2020 was performed. Charts were obtained from homeless patients seen at free general clinics held shelters in Chicago, IL (781 charts) and in Champaign, IL (31 charts). Records reporting at least one otolaryngology disease in a patient experiencing homelessness were included in this study. Patients were considered homeless if they resided at the shelter at the time of their appointment. To determine common barriers to care, a simple yes/no questionnaire was administered to residents at west-side Chicago homeless shelters. Questions addressed barriers to health care access that had been mentioned by patients seen at free clinics.

RESULTS

Chart review findings demonstrated that 14.3% (n = 142) of all homeless patients seen at free in-shelter clinics were seen for ENT-related disorders. Survey results revealed that 76.3% (n = 71) of respondents believed that telemedicine services would be useful in shelters. 74.2% (n = 69) stated they were unable to afford prescribed medications. 93.5% (n = 87) stated that better access to transportation would increase their likelihood of seeking care.

CONCLUSIONS

In our attempt to bridge this inequity, we have launched a hybrid in-person/virtual care program to improve access to otolaryngology care for the homeless community.

Treatment, Management, and Otolaryngology Consultation for Epistaxis in the Emergency Room: An Institutional Experience

BACKGROUND

Epistaxis is a common reason for emergency department (ED) visits, accounting for approximately 1 of every 200 ED visits in the United States annually and up to one-third of all otolaryngology (ENT)-related ED encounters.

OBJECTIVES

To detail reasons for ENT consultation for epistaxis in the ED, understand how consultation impacts patient care, assess follow-up patterns after emergency care, and study patient care after transfer or referral into the ED.

METHODS

Retrospective chart review of 592 adult patients with epistaxis managed in a tertiary care ED setting between 2017 and 2018. Patients with known follow-up, ENT consult in the ED, or admission were included, while patients with trauma, recent head and neck surgery, or abnormal anatomy were excluded.

RESULTS

The most common reasons for ENT consultation for epistaxis were for advanced management, referral to the ED from an outside facility or provider, and recent head and neck surgery. In total, 48.2% of patients treated for epistaxis in the ED received an ENT consultation. ENT consultation was associated with a higher likelihood of receiving absorbable or nonabsorbable packing (92.4% vs 36.1%). In total, 40.4% of patients referred into the ED from an outside facility or provider had no change in their management after receiving an ENT consult. Patients referred to the ED and White patients were significantly more likely to receive an ENT consult. Secondary analyses revealed that more White patients had an established outpatient ENT provider than patients of other races. On multivariate analysis, patients who received an ENT consult spent 75.2 min longer in the ED.

CONCLUSION

The high percentage of patients referred or transferred to the ED for epistaxis management with no change in interventions after ENT consultation indicates a continued need to develop more precise clinical care pathways. Additionally, there may be gaps between White and non-White patients in access to ENT care.

A Quantitative Analysis of Smartphone-Based Endoscopy and Video Tower Endoscopy

OBJECTIVES

Examine the differences between traditional tower-based endoscopy (TBE) and smartphone-based endoscopy (SBE) using objective measures of cost, setup time, and image quality.

METHODS

Cost analysis study and randomized single-blinded prospective trial was performed at a tertiary academic health center. Twenty-three healthcare providers, 2 PA-C, 9 residents, 2 fellows, 10 attendings varying in practice from 1 to 27 years were a part of the study. Actual cost analysis was used for purchase of the Karl Storz video tower system and the Save My Scope smartphone-based endoscopy system for cost analysis. For setup time, providers entered a room and were randomized to set up either an SBE or TBE system and timed from room entry to a visible on-screen image. A crossover was then performed so all providers performed both setups. For image discernment, standardized photos of a modified Snellen's test were sent via text message to providers who were blinded as to which photo represented which system. Practitioners were randomized as to which photo to receive first.

RESULTS

Cost savings was 95.8% ($39,917 USD) per system. Setup time for the smartphone system was 46.7 seconds less than video tower system on average (61.5 vs 23.5 seconds; P < .001, 95% CI: 30.3-63.1 seconds). Level of visual discernment was slightly better for SBE over TBE, with reviewers able to identify Snellen test letters at a size of 4.2 mm with SBE versus 5.9 mm with TBE (P < .001).

CONCLUSIONS

Smartphone-based endoscopy was found to be cheaper, quicker to set up, and to have marginally better image quality when transmitted via messaging than tower-based endoscopy, although the clinical significance of these visual differences are unknown. If appropriate for their needs, clinicians should consider smartphone-based endoscopy as a viable option for viewing and collaborating on endoscopic images from a fiberoptic endoscope.

Trends Following Implementation of an Otolaryngology Hospitalist Model in a Tertiary Care Setting

OBJECTIVES

The otolaryngology hospitalist (OH) model is an emerging paradigm for inpatient and acute patient care. This study presents encounter volume before and after the implementation of an OH service. Postimplementation trends are evaluated.

STUDY DESIGN

Retrospective administrative and clinical database review.

SETTING

Tertiary care university hospital.

METHODS

This review includes 2 distinct time frames (2008-2012, 2014-2018), representing periods before and after OH implementation. The number of billed patient encounters is compared between these 2 periods using the hospital data warehouse. Additional data is evaluated for the postimplementation period, using a clinical database. Encounter type, the reason for consultation, procedures, and requesting service/location are described.

RESULTS

After the OH implementation, there was a 451% increase in evaluation and management encounters submitted for billing. Since the OH model inception, there was an overall increase in encounters (849-910), procedures performed (319-345), and operative cases (46-54) per year. Each inpatient consultation request generates one or more procedures on average. Common reasons for consultation include sinonasal pathology (20.3%), dysphonia/dysphagia (17.5%), and airway evaluation (15%). Critical Care (24%), Emergency Medicine (21%), and Hospital Medicine (21%) requested most of the Otolaryngology consults. Most consults were seen on the inpatient medical/surgical floor (46%), with the ICU (27%) and the Emergency Department (22%) being the next most common locations.

CONCLUSIONS

The OH model is an evolving paradigm that is viable and offers timely, specialized care for patients in a hospital or acute care setting.

A quiet place: The impact of the word "quiet" on clinical workload

Purpose

This study aimed to determine the impact of uttering the word "quiet" on clinical workload during the overnight otolaryngology call shift and understand the factors contributing to resident busyness.

Materials and Methods

A multicenter, single-blind, randomized-controlled trial was conducted. A total of 80 overnight call shifts covered by a pool of 10 residents were randomized to the quiet or to the control group. At the start of shift, residents were asked to state aloud, "Today will be a quiet night" (quiet group) or "Today will be a good night" (control group). Clinical workload, as measured by number of consults, was the primary outcome. Secondary measures included number of sign-out tasks, unplanned inpatient and operating room visits, number of phone calls and hours of sleep, and self-perceived busyness.

Results

There was no difference in the number of total (P = 0.23), nonurgent (P = 0.18), and urgent (P = 0.18) consults. Tasks at signout, total phone calls, unplanned inpatient visits, and unplanned operating room visits did not differ between the control and quiet groups. While there were more unplanned operating room visits in the quiet group (29, 80.6%) compared to the control group (34, 94.4%), this was not found to be significant (P = 0.07). The majority of residents reported feeling "not busy" during control nights (18, 50.0%) compared to feeling "somewhat busy" during quiet nights (17, 47.2%; P = 0.42).

Conclusion

Contrary to popular belief, there is no clear evidence that uttering the word "quiet" significantly increases clinical workload.

Blood transfusion demands in a tertiary otolaryngology, head and neck centre: A 5-year retrospective cohort study

OBJECTIVES

To retrospectively analyse and report the utilisation of red blood cell (RBC) transfusion in a tertiary otolaryngology, head and neck centre in the United Kingdom.

BACKGROUND

Twenty-seven per cent of RBC transfusions were for surgical indications in a 2014 England and North Wales survey. Currently, there is limited literature on RBC transfusions in Otolaryngology.

METHODS/MATERIALS

All inpatients admitted primarily under the care of the Otolaryngology, Head and Neck service between January 2015 and December 2019 were analysed. The primary outcomes of interest were number of units of RBC transfused over 5 years and distribution across clinical indications. Secondary outcome measure was cost of RBC transfusions over the same time period.

RESULTS

Most patients receiving transfusions are aged in their sixth and seventh decades. Epistaxis patients utilised 105 RBC units over the 5 years (56% of total RBC units) with emergency epistaxis accounting for 78% of use. Post-operative Head & Neck Cancer surgery with and without reconstruction required 47 RBC units over 5 years (25% of total RBC units). The mean cost incurred by the department over the 5-year period was £6171.49 (SD 1460.25). The cost has fallen by over £2000 over the 5-year period.

CONCLUSION

Blood transfusion use has fluctuated over the last 5 years. Epistaxis and post-operative Head and Neck cancer cases account for significant use compared with other patient groups. Prehabilitation strategies will add value towards mitigating future consumption of RBC.

The power of a checklist: Decrease in emergency department epistaxis transfers after clinical care pathway implementation

BACKGROUND

Annually, epistaxis costs US hospitals over $100 million dollars. Many patients visit emergency departments (ED) with variable treatment, thus providing opportunity for improvement.

OBJECTIVE

To implement an epistaxis clinical care pathway (CCP) in the ED, and analyze its effects on treatment and ED transfers.

METHODS

An interdisciplinary team developed the CCP to be implemented at a tertiary hospital system with 11 satellite EDs. The analysis included matched eight-month periods prior to pathway implementation and after pathway implementation. Subjects included patients with ICD-10 code diagnosis of epistaxis. Patients under 18 years old, recent surgery or trauma, or bleeding disorders were excluded. There were 309 patients from the pre-implementation cohort, 53 of which were transferred and 37 met inclusion criteria; 322 from the post-implementation cohort, 37 of which were transferred, and 15 met inclusion criteria. Outcome measures included epistaxis intervention by ED providers and otolaryngologists before and after pathway implementation.

RESULTS

CCP implementation resulted in a 61% reduction in patient transfers (p < 0.001). ED providers showed a 51% increase in documentation of anterior rhinoscopy with proper equipment, 34% increased use of topical vasoconstrictors, 40% increased use of absorbable packing, 7% decrease in use of unilateral non-absorbable packing, and 17% decrease in use of bilateral non-absorbable packing.

CONCLUSIONS

Prior to CCP implementation, ED treatment of epistaxis varied significantly. CCP resulted in standardized treatment and significant reduction in transfers. A CCP checklist is an effective way to standardize care and prevent unnecessary hospital transfers.

Trends in otolaryngology consult volume at an academic institution from 2014 to 2018

OBJECTIVE

To evaluate changes in emergency department and inpatient consult volumes of an otolaryngology service at an academic medical center from 2014 to 2018.

METHODS

A retrospective review of all otolaryngology consults in the electronic medical record from March 2014 through December 2018 was completed. The total number of consults was recorded to determine changes in consult volume over time. Additional parameters were analyzed including volume of weekday, night and weekend, adult, pediatric, emergency department, and inpatient consults.

RESULTS

From 1 March 2014 to 31 December 2018, a total of 8806 consults were seen by the otolaryngology service. In the first year, a total of 990 consults were seen. In the final year of the time period, a total of 2416 consults were seen. This represents a 144% increase in consults over the examined time period. Similar increasing trends were seen when consults were analyzed by weekday, night/weekend, pediatric, adult, emergency department, and inpatient consults.

CONCLUSIONS

This is one of the first studies examining trends in otolaryngology consult volumes at an academic medical center in the United States. Our data show that the volume of consults has increased by 144% in a 4-year time period, predominantly due to an increase in emergency department consultations. This study demonstrates the increasing burden of emergency department consultations on an otolaryngology service at an academic medical center and highlights a potential role for increasing and improving provider availability.

The Role of Speech-Language Pathologists in Otolaryngology Resident Education

OBJECTIVES/INTRODUCTION

Laryngology is an expanding field that has been increasingly incorporated into otolaryngology resident training programs nationwide. The exposure to the field is variable across training programs, despite the fact that laryngological complaints comprise a large proportion of consultations to otolaryngologists. Laryngology education is vital for the care of patients with voice, swallowing, and airway complaints as well as for the appropriate referral of patients to the laryngology team for specialized care. Speech-language pathologists (SLPs) specialized in voice and swallowing disorders are well-trained in the assessment and treatment for these populations. This team recently published a paper regarding the experience of laryngology education in residency. During analysis of the results, an interesting beneficial trend developed regarding the positive impact of exposure to SLPs. This appeared to be distinct and deserved further analysis and discussion. We propose that involving SLPs in resident education may greatly enhance their training in laryngology.

METHODS

As per our previous paper, a cross sectional, multi-institutional study was designed to assess the exposure of residents to laryngology. Descriptive statistics were obtained for questions involving exposure to SLPs. Fisher's exact test was used to compare differences between groups.

RESULTS

Most respondents (135/151, 89.4%) indicated having SLPs specializing in voice and swallowing disorders in their departments, although only half (77/151, 51.0%) stated that they spent formal time with them during training. Results show that residents with formal training with SLPs were more comfortable interpreting videofluoroscopic swallow studies (VFSS) (P = .0032). Residents with SLPs in their departments were also more likely to feel confident in terminology to describe different dysphonic voices (P = .0213).

CONCLUSION

Formal time with SLPs within otolaryngology residency programs varies across the country. Speech-language pathologists are a useful resource for laryngology resident training and should be included in their education.

Gaps in Training: Misunderstandings of Airway Management in Medical Students and Internal Medicine Residents

Objectives

(1) Evaluate baseline airway knowledge of medical students (MSs) and internal medicine (IM) residents. (2) Improve MS and IM resident understanding of airway anatomy, general tracheostomy and laryngectomy care, and management of airway emergencies.

Methods

A before-and-after survey study was carried out over a single academic year. MS and IM resident knowledge was evaluated before and after an educational, grand rounds–style lecture reviewing airway anatomy, tracheostomy tube components, tracheostomy and laryngectomy care, and clinical vignettes. The primary outcome measure was change in pre- and postlecture survey scores.

Results

Prelecture surveys were completed by 90 participants, and 83 completed a postlecture assessment. Postlecture scores were statistically improved for all questions on the assessment ( P < .001). Level of training did not confer an improved pre- or postlecture survey score.

Discussion

While the majority of participants in our study had previously cared for patients with a tracheostomy or laryngectomy, less than half were able to correctly address basic airway emergencies. Senior IM residents were no more proficient than MSs in addressing airway emergencies. The lack of formal airway training places patients at risk with routine care and in emergencies, demonstrating the need for formal airway education for early medical trainees.

Implications for Practice

Our data demonstrate a serious gap in MS and IM resident knowledge with respect to emergent airway care in patients with tracheostomies and laryngectomies. An interdepartmental collaborative curriculum offers a realistic and potentially life-saving solution for medical trainees.

Resource Utilization and Billing in a Resident-Managed Inpatient Consult Service

OBJECTIVE

Patient care delivered by residents is an educational opportunity to foster autonomy. These services, however, may not be billed without direct faculty supervision. This quality improvement project analyzes descriptive data, procedures, and billing from an academic otolaryngology-head and neck surgery department's inpatient consult service.

METHODS

This prospective cohort study collected descriptive and billing data on all consults over 30 consecutive days. Data collected described bedside procedures and operative interventions. Encounters were Current Procedural Terminology coded and equivalent work relative value unit (wRVU) calculated. Codes submitted for billing were reviewed to identify opportunities for inpatient billing improvement.

RESULTS

Ninety-eight new consults were included, and 105 bedside procedures were performed. Flexible laryngoscopy (n = 27), I&D (incision and drainage; n = 11), and suturing (n = 11) were the most performed bedside procedures. Operative intervention was required in 15 encounters. The inpatient consult team provided the equivalent of 391.39 wRVU. Seventy-three percent of operative compared to 3% of bedside procedures were submitted for billing.

DISCUSSION

The productivity of our team approximated 61.8% of a full-time general otolaryngologist but with decreased billing submissions. Balance between resident autonomy, education, quality patient care, and the ability to capture service revenue is complex. Strategies other institutions have used to capture missed billing opportunities have included a hospitalist model, mid-level providers, and resident billing.

IMPLICATIONS FOR PRACTICE

This study characterizes an academic inpatient consult service. Results describe a case for improving the structure of the inpatient consult service, caution that studies collecting data via department billing may underrepresent services, and suggest alternative service structures to overcome identified billing limitations.

Assessing the Breadth of Laryngology Training in Otolaryngology Residency Programs

INTRODUCTION

Laryngology is an expanding field with incorporation in resident training nationwide. However, the breadth of training in laryngology reported by residents has not been previously evaluated. This project assesses the variability in laryngology training among otolaryngology residents.

METHODS

A cross sectional, multi-institutional study was performed with an anonymous survey sent to residents and laryngology fellows nationally to assess different laryngology training practices.

RESULTS

There were 151 responses to the survey with 9.6% response rate. 49 (32.9%) did not have a designated laryngology rotation. 134 (89.3%) had a fellowship-trained laryngologist as part of their institution. The greatest percentage of respondents intended to pursue general ENT (31; 20.7%). PGY5 responses were analyzed for total residency exposure showing, 66.7% of PGY5s received training to identify different types of dysphonic voices through auditory findings alone. 61.9% could interpret a videoflouroscopic swallow study.  Regarding surgical cases, 52.4% had been involved in open cricopharyngeal myotomies, 76.2% in endoscopic cricopharyngeal myotomies, and 100% in subglottic stenosis cases. Residents pursuing a career in laryngology and those with a designated laryngology rotation had more exposure to laryngeal surgeries and office-based procedures than their peers.

CONCLUSION

Laryngology training and exposure varies across the country. Residents are more familiar with airway than voice and swallowing related pathology. Residents with a designated laryngology rotation and those pursing laryngology fellowships were more likely to have exposure to laryngeal surgery and office-based procedures. Programs with a laryngologist likely had higher response rates so the true laryngology exposure may be more limited than our data suggests.

Impact of coronavirus (COVID-19) on otolaryngologic surgery: Brief commentary

Background

The Coronavirus disease—2019 (COVID‐19) pandemic is a global health crisis and otolaryngologists are at increased occupational risk of contracting COVID‐19. There are currently no uniform best‐practice recommendations for otolaryngologic surgery in the setting of COVID‐19.

Methods

We reviewed relevant publications and position statements regarding the management of otolaryngology patients in the setting of COVID‐19. Recommendations regarding clinical practice during the severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) outbreaks were also reviewed.

Results

Enhanced personal protective equipment (N95 respirator and face shield or powered air‐purifying respirator, disposable cap and gown, gloves) is required for any otolaryngology patient with unknown, suspected, or positive COVID‐19 status. Elective procedures should be postponed indefinitely, and clinical practice should be limited to patients with urgent or emergent needs.

Conclusion

We summarize current best‐practice recommendations for otolaryngologists to ensure safety for themselves, their clinical staff, and their patients.

Characteristics, Burden, and Necessity of Inpatient Consults for Academic and Private Practice Urologists

OBJECTIVE

To compare differences in the characteristics and outcomes of inpatient consults between academic and private practice urologists.

MATERIALS AND METHODS

We performed a retrospective review of urology consults at a large tertiary-care hospital from June 1st, 2017 to June 30th, 2018. Patient demographics, timing of consult, location of consult, reasons for consult, requesting physicians, and procedures performed were analyzed and compared.

RESULTS

A total of 613 consults were identified. The most common consults were for a Foley catheter/suprapubic tube (16%), urinary retention (15%), kidney/bladder stones (11%), and hematuria (11%). Seventy-seven percent of the consults were seen in the day time and 79% were seen on the weekdays. One hundred and ten (18%) consults resulted in an operative intervention during the same admission. The others required a Foley catheter placement or suprapubic exchange (17%), bedside procedure (9%), or interventional radiology procedure (4%). The remaining 319 consults (52%) required no intervention and were considered potentially unnecessary. There were no differences in the timing of the consults and the need for intervention between academic and private practice urologists (P = .20). Only 37% of patients followed up as an outpatient. These potentially unnecessary consults resulted an annual loss of 265.8 hours for the urologists and $44,376.09 in excess health care costs.

CONCLUSION

Over half of inpatient urologic consultations required no urologic intervention and therefore represented potential overuse of urgent inpatient specialty care. This may contribute towards the growing epidemic of burnout in urology. Further work needs to be done to educate other hospital services and nurses to minimize these unnecessary consults.

Consultation Intervention Rates for the Otolaryngology Service: A Large Metropolitan Hospital Experience

CONTEXT

The purpose of this study was to evaluate the types of consultations received by an otolaryngology service at a 772-bed large metropolitan, MI-based hospital.

METHODS

The authors performed a retrospective review of the specific types of consultations received during calendar year 2016.

RESULTS

A total of 518 consultations were reviewed and analyzed by the first and second authors (MM, CB). Consultations with low intervention rates included dysphagia (difficulty swallowing) (32.3%), dysphonia (difficulty speaking) (16%), otalgia (earache) (20.8%), hearing loss (13.3%), rule out vocal cord dysfunction (0%), and vertigo/dizziness (0%). Epistaxis (nosebleed) was the most frequent reason for consultations, and angioedema (lip or airway swelling) was the most common airway-related consultation. Notably, emergent or urgent surgery was only performed on 4.6% of sample patients. Several common consultation reasons (e.g., longer-term hearing loss evaluation and cerumen ("earwax") removal) could have been deferred for clinic-based evaluation where audiograms and microscopes are more readily available.

CONCLUSIONS

These findings suggest areas for continuing education for primary care provider and resident education to place more appropriate hospital consultations. Annual resident lectures to prepare junior residents for the most common call scenarios (i.e., control epistaxis and incision and drainage of peritonsillar abscesses) could be helpful in this area. In addition, didactic lectures for primary care physicians on how to evaluate patients with dysphagia may be of value as this was a common consult for otolaryngologist referrals.

Identifying Complications and Optimizing Consultations following Transradial Arterial Access for Cardiac Procedures

BACKGROUND

The radial approach to cardiac procedures has become increasingly common. Although previous studies have suggested a favorable risk profile, serious complications can occur. The purpose of this study is to examine the incidence, subsequent treatment, and outcome of all suspected significant neurovascular complications following transradial cardiac procedures at a large US hospital.

METHODS

We reviewed all patients who underwent a left heart catheterization, coronary angiogram, or percutaneous coronary intervention via the transradial approach at a single large academic medical center in the United States between 2010 and 2016. Consultations to the vascular and hand surgery services were examined to assess demographic variables, risk factors, presenting symptoms, subsequent treatment, and outcome of all serious complications.

RESULTS

A total of 9,681 radial access cardiac procedures were performed during the study period. Twenty-four cases (0.25%) were suspected to have major complications and subsequently received consults. A total of 18 complications were diagnosed, including 8 vascular injuries or perforations, 4 hematomas, 4 radial artery occlusions, 1 case of compartment syndrome, and 1 severe radial artery spasm. Of the complications noted, 3 (16.7%) required operative interventions, but all recovered neurovascular function.

CONCLUSIONS

Radial artery access for cardiac procedures has become increasingly common and has been associated with a low rate of major peripheral neurovascular complications. The majority (83.3%) of complications were successfully treated with a nonoperative management algorithm.

An Evaluation of On-Call Otolaryngology Consultations: Assessing an Increasing Workload

Objective:

This study compares the volume of on-call otolaryngology consultations in a tertiary care center over a 5-year period. The objective of this study was to identify changes in the volume of consultations in an inpatient setting.

Methods:

A cross-sectional retrospective study was performed to determine the volume of consultations. The years 2010 and 2015 were the timepoints for the cross-sectional analysis. A review of electronic medical records was performed to identify all patients associated with the otolaryngology service from the emergency department, inpatient wards, and intensive care units. The primary outcome was the number of otolaryngology consultations per year.

Results:

The number of on-call consultations in 2010 was 992. In 2015, the number of on-call consultations was 2174. This represents a 120% increase in the number of consultations over a 5-year period ( P < .001).

Conclusion:

There has been a significant increase in the volume of on-call otolaryngology consultations at our tertiary care center. This increase has the potential to adversely affect patient care. A better understanding of the cause of this increase may allow policymakers and health care practitioners to improve patient access, physician workloads, and resource allocation.

Mobile Technology in E-Learning for Undergraduate Medical Education on Emergent Otorhinolaryngology-Head and Neck Surgery Disorders: Pilot Randomized Controlled Trial

BACKGROUND

The use of mobile technology in e-learning (M-TEL) can add new levels of experience and significantly increase the attractiveness of e-learning in medical education. Whether an innovative interactive e-learning multimedia (IM) module or a conventional PowerPoint show (PPS) module using M-TEL to teach emergent otorhinolaryngology-head and neck surgery (ORL-HNS) disorders is feasible and efficient in undergraduate medical students is unknown.

OBJECTIVE

The aim of this study was to compare the impact of a novel IM module with a conventional PPS module using M-TEL for emergent ORL-HNS disorders with regard to learning outcomes, satisfaction, and learning experience.

METHODS

This pilot study was conducted at an academic teaching hospital and included 24 undergraduate medical students who were novices in ORL-HNS. The cognitive style was determined using the Group Embedded Figures Test. The participants were randomly allocated (1:1) to one of the two groups matched by age, sex, and cognitive style: the IM group and the PPS group. During the 100-min learning period, the participants were unblinded to use the IM or PPS courseware on a 7-inch tablet. Pretests and posttests using multiple-choice questions to evaluate knowledge and multimedia situational tests to evaluate competence were administered. Participants evaluated their satisfaction and learning experience by the AttrakDiff2 questionnaire, and provided feedback about the modules.

RESULTS

Overall, the participants had significant gains in knowledge (median of percentage change 71, 95% CI 1-100, P<.001) and competence (median of percentage change 25, 95% CI 0-33, P=.007) after 100 min of learning. Although there was no significant difference in knowledge gain between the two groups (median of difference of percentage change 24, 95% CI -75 to 36; P=.55), competence gain was significantly lower in the IM group compared with the PPS group (median of difference of percentage change -41, 95% CI -67 to -20; P=.008). However, the IM group had significantly higher scores of satisfaction (difference 2, 95% CI 2-4; P=.01), pragmatic quality (difference 1.7, 95% CI 0.1-2.7; P=.03), and hedonic stimulation (difference 1.9, 95% CI 0.3-3.1; P=.01) compared with the PPS group. Qualitative feedback indicated that the various games in the IM module attracted the participants' attention but that the nonlinearly arranged materials affected their learning.

CONCLUSIONS

Using M-TEL for undergraduate medical education on emergent ORL-HNS disorders, an IM module seems to be useful for gaining knowledge, but competency may need to occur elsewhere. While the small sample size reduces the statistical power of our results, its design seems to be appropriate to determine the effects of M-TEL using a larger group.
