RESUMEN
The most common form of heart failure occurs with normal systolic function and often involves cardiac hypertrophy in the elderly. To clarify the biological mechanisms that drive cardiac hypertrophy in aging, we tested the influence of circulating factors using heterochronic parabiosis, a surgical technique in which joining of animals of different ages leads to a shared circulation. After 4 weeks of exposure to the circulation of young mice, cardiac hypertrophy in old mice dramatically regressed, accompanied by reduced cardiomyocyte size and molecular remodeling. Reversal of age-related hypertrophy was not attributable to hemodynamic or behavioral effects of parabiosis, implicating a blood-borne factor. Using modified aptamer-based proteomics, we identified the TGF-ß superfamily member GDF11 as a circulating factor in young mice that declines with age. Treatment of old mice to restore GDF11 to youthful levels recapitulated the effects of parabiosis and reversed age-related hypertrophy, revealing a therapeutic opportunity for cardiac aging.

PURPOSE/OBJECTIVES: Current guidelines do not recommend routine surveillance imaging as part of follow-up care for patients treated for locoregional endometrial carcinoma. This study seeks to determine the potential benefit of routine surveillance imaging by evaluating outcomes of patients whose recurrences were detected on routine surveillance compared to those whose recurrences were identified after presenting with symptoms. MATERIALS/METHODS: We conducted a retrospective review of patients who developed recurrence after surgical treatment, with or without adjuvant therapy, for locoregional endometrial carcinoma. A total of 149 patients were identified with adequate clinical information regarding the recurrence. Cox proportional hazards regression analysis was used to estimate overall survival and progression-free survival. RESULTS: The median age of patients at diagnosis was 69.2 years (range, 38.0-99.5 years). Initial stages included stage I, 49.7%; stage II, 10.1%; stage III, 38.3%; and stage IV, 1.3%. Histologic diagnoses included endometrioid adenocarcinoma, 48.3%; and other diagnoses (including papillary serous carcinoma, clear cell carcinoma, and carcinosarcoma), 51.7%. Patients were initially treated with a variety of therapies: surgery alone in 20.8%, surgery and radiation in 25.5%, surgery and chemotherapy in 12.1%, and trimodality therapy in 41.6%. Sites of recurrence included 20.8% vaginal, 14.8% pelvic and 64.4% distant sites. Recurrences were detected asymptomatically in 86 patients (57.7%) and symptomatically in 63 patients (42.3%). Of those detected asymptomatically, 80.2% were detected by imaging. Overall, when comparing symptomatic versus asymptomatic recurrences, there was no difference in overall survival (hazard ratio, 1.24; 95% confidence interval, 0.84-1.83; P = 0.29) or progression-free survival (hazard ratio, 1.14; 95% confidence interval, 0.77-1.70; P = 0.52). CONCLUSIONS: Patients who develop asymptomatic recurrences of their endometrial carcinoma do not seem to have a better prognosis than those who present with symptomatic recurrences. Thus, these results do not support routine imaging surveillance for patients treated for locoregional endometrial carcinoma. Further prospective evaluation is needed.

OBJECTIVE: To describe the demographics, tumor characteristics, and prognostic features of mucoepidermoid carcinoma of the parotid gland. MATERIALS AND METHODS: A retrospective study of the National Cancer Database was reviewed for all mucoepidermoid carcinomas of the parotid gland between 2004 and 2012). Patient demographics and tumor characteristics were abstracted and analyzed. Univariate and multivariate Cox multivariate regression models were used to identify predictors of survival. RESULTS: A total of 4431 patients met inclusion criteria. Average age at diagnosis was 57â¯years (median 62, SD 19), with no overall sex preference (52% female), and majority white (78%). The 1-year overall survival was 92.9% (95% CI [92.1-93.6]) and 5-year overall survival was 75.2% (95% CI [73.8-76.7%]). Median overall survival was not reached at 5â¯years. Factors associated with decreased survival were increasing age, comorbidities, high tumor grade, advanced pathologic group stage, and positive surgical margins. Female sex was the only factor associated with improved survival. Controlling for either histopathologic grade or pathologic stage to determine how patient demographics and tumor characteristics affected overall survival yielded similar results. Of note, intermediate grade tumors, although not independently associated with worse survival, when seen in conjunction with tumors ≥T2 and/or ≥N2, a negative impact on overall survival was seen. CONCLUSION: Although mucoepidermoid carcinoma of the parotid gland is the most common parotid gland malignancy, it is still a rare tumor with a lack of large population-based studies. Advanced stage and high-grade tumors are significant predictors of decreased survival. Females have improved survival compared to males.

Objective: Gaps in gender-based equity persist in academic otolaryngology. Here we present a needs-based assessment of otolaryngology faculty and trainees regarding facilitators and barriers to professional satisfaction and career development in academic medicine. Methods: A qualitative study of otolaryngology faculty, trainees, and administrators who identify as women at an academic tertiary care center was performed from 2020 to 2021 using focus groups and semi-structured interviews. Five confidential, virtual focus group sessions moderated by a third-party executive coach were audio-taped, transcribed, and reviewed for thematic content. Results: Of 48 women invited, 77% participated (18 faculty/administrative leaders, 10 residents/fellows, 4 audiologists). Participants noted direct patient care, support from colleagues who identify as women, and the transition to virtual meetings as facilitators of current professional satisfaction. Five themes emerged as barriers to workplace satisfaction and career development including (1) limited professional schedule flexibility, (2) competing commitments such as childcare exacerbated by pandemic, (3) lack of visible departmental leadership who identify as women, (4) perceived lack of organic sponsorship within subspecialty divisions, and (5) frequent identity-associated microaggressions from patients and staff outside the department. Strategies identified for improving gender-based equity included (1) promoting department-wide awareness of workplace gender-based differences, (2) implicit bias training within established programming such as grand rounds conferences, and (3) novel faculty programming such as leadership development training and formal junior faculty mentorship. Conclusion: Confidential needs-based assessment of otolaryngology faculty and trainees identified both persistent gaps and strategies to enhance recruitment, support career development, and grow professional satisfaction of women within academic otolaryngology. Level of Evidence: 3.
RESUMEN
BACKGROUND: Large full-thickness lip defects present a reconstructive challenge. OBJECTIVE: To describe the impact on clinical outcomes and institutional cost of the depressor anguli oris myocutaneous (DAOM) flap as an axial pattern transposition flap for reconstruction of large, full-thickness lip defects. METHODS: A multicenter retrospective cohort study of adults with large full-thickness lip defects who underwent DAOM flap reconstruction from 2011 to 2018 was conducted. DAOM flap anatomy and surgical technique were reviewed. The primary outcome of flap viability as well as additional clinical outcomes of postoperative complications and functional results were documented with follow-up ranging up to 11 years. Median length of stay and average institutional cost of care were analyzed. RESULTS: A total of 12 patients underwent DAOM flap reconstruction for large full-thickness lip defects. There was 100% flap survival with no episodes of reoperation or readmission. All patients reported maintenance of distinct oral commissures, wide oral opening and full gingivolabial sulcus, excellent oral competence, and intelligible speech. Mean case length was 144 ± 11.5 min with a mean length of stay of 1.6 ± 0.5 days and estimated mean institutional cost of $3766.67 ± $1167.06. CONCLUSIONS: The DAOM flap is an excellent reconstructive option for large full-thickness lip defects with strong functional results and limited donor site morbidity and institutional cost of care.

OBJECTIVE: Traditional hospital accounting fails to provide an accurate cost of complex surgical care. Here we describe the application of time-driven activity-based costing (TDABC) to characterize costs of head and neck oncologic procedures involving free tissue transfer. STUDY DESIGN: Retrospective cohort study. SETTING: Single tertiary academic medical center. METHODS: An analysis of head and neck oncologic procedures involving microvascular free flap reconstruction from 2018 to 2020 (n = 485) was performed using TDABC methodology to measure cost across operative case and postoperative admission, using quantity of time and cost per unit of each resource to characterize resource utilization. Univariate and generalized linear mixed models were used to examine associations between patient and hospital characteristics and cost of care delivery. RESULTS: The total cost of care delivery was $41,905.77 ± 21,870.27 with operating room (OR) supplies accounting for only 10% of the total cost. Multivariable analyses identified significant cost drivers including operative time, postoperative length of stay, number of return trips to the OR, postoperative complication, number of free flaps performed, and patient transfer from another hospital or via emergency department admission (P < .05). CONCLUSION: Operative time and postoperative length of stay, but not operative supplies, were primary drivers of cost of care for head and neck oncology cases involving free tissue transfer. TDABC offers granular cost characterization to inform cost optimization through unused capacity identification and postoperative admission efficiencies.

Our nation faces contentious questions regarding reproductive rights and access to abortion which have long been viewed as beyond the scope of otolaryngology. The broad implications of the recent Supreme Court ruling in Dobbs v Jackson Women's Health Organization (Jackson) impact all people who are, or can become, pregnant and their health care providers. The consequences for otolaryngologists are thus far-reaching and poorly understood. Here we describe how the post-Dobbs landscape is relevant to the practice of otolaryngology and offer suggestions for how otolaryngologists can best respond, prepare, and support their patients in this tenuous political landscape.

Objectives: To assess the impact of applicant and program characteristics on preference signaling outcomes during the 2021 and 2022 application cycles in otolaryngology. Methods: The Texas Seeking Transparency in Applications to Residency survey was used for otolaryngology applicants during the 2021 and 2022 match years. The primary outcome of interest was signal yield, defined as the number of interviews at signaled programs divided by the total number of signals sent. Associations with applicant-reported characteristics, geographic connections to programs, and program reputation were assessed. Results: On average 59.5% of signals resulted in an interview (signal yield). There was a positive correlation between the number of signals sent to a program with a reported geographic connection and signal yield, with each additional signal resulting in a 3.4% increase in signal yield (p = .03). Signal yield was positively associated with number of publications (p < .001); number of abstracts, posters, and presentations (p = .04); and whether the applicant took a research year (p = .003). Applicants with higher USMLE Step 1 (p = .01) and Step 2 (p = .003) scores, publications (p = .03), volunteer (p = .008) and leadership (p = .001) experiences received a lower percentage of their total interviews from signaled programs whereas applicants from the 3rd (p < .001) and 4th (p = .03) cumulative class ranked quartiles received a higher percentage of their total interviews from signaled programs. Conclusions: Signal yield appears to have a significant association with geographic connections to programs and applicant competitiveness. This study may help applicants, advisors, and programs maximize the benefit of the preference signaling system.Levels of evidence: Level 4.
RESUMEN
BACKGROUND: The impact of monoclonal antibody therapy (mAB) for advanced head and neck cancer on end-of-life health care utilization and costs has yet to be adequately studied. METHODS: Retrospective cohort study of patients aged 65 and over with a diagnosis of head and neck cancer between 2007 and 2017 within the SEER-Medicare registry assessing the impact of mAB therapy (i.e., cetuximab, nivolumab, or pembrolizumab) on end-of-life health care utilization (ED visits, inpatient admissions, ICU admissions, and hospice claims) and costs. RESULTS: Of 12 544 patients with HNC, 270 (2.2%) utilized mAB therapy at the end-of-life period. On multivariable analyses adjusting for demographic and clinicopathologic characteristics, there was a significant association between mAB therapy and emergency department visits (OR: 1.38, 95% CI: 1.1-1.8, p = 0.01) and healthcare costs (ß: $9760, 95% CI: 5062-14 458, p < 0.01). CONCLUSIONS: mAB use is associated with higher emergency department utilization and health care costs potentially due to infusion-related and drug toxicity expenses.

PURPOSE: To use a hybrid method, combining statistical profiling, machine learning (ML), and clinical evaluation to predict emergency department (ED) visits among patients with head and neck cancer undergoing radiotherapy. MATERIALS AND METHODS: Patients with head and neck cancer treated with radiation therapy from 2015 to 2019 were identified using electronic health record data. Records from 60 days before 90 days after treatment were analyzed. Statistical profiling and ML were used to create a predictive model for ED visits during or after radiation therapy. A comprehensive set of variables were studied. Multiple ML models were developed including extreme gradient-boosted decision tree and generalized logistic regression with comparison of multiple predictive performance metrics. RESULTS: Of the 1,355 patients studied, 13% had an ED visit during or after treatment. Our hybrid methodology enabled evidence-based winnowing of candidate features from 141 to 11 with clinically applicable, evidence-based thresholds. Extreme gradient boosting had the highest area under the curve (0.81 ± 0.06) with a sensitivity of 0.89 ± 0.10 and exceeded generalized logistic regression (area under the curve 0.64 ± 0.02). Significant predictors of ED visits during treatment included increasingly complex opioid use, number of prior ED visits, tumor volume, rate of change of blood urea nitrogen, total bilirubin, body mass index, and distance from hospital. CONCLUSION: Our approach combining bootstrapped statistical profiling and ML importance analysis supported integration of clinician input to identify a distilled set of phenotypical characteristics for developing ML models predicting which patients undergoing head and neck cancer radiation therapy were at risk for ED visits.

Importance: Because microvascular free flap reconstruction is increasingly used to restore function in patients with head and neck cancer, there is a growing need for evidence-based perioperative care. Objective: To assess the association of different team-based surgical approaches with intraoperative and postoperative outcomes for patients undergoing head and neck free flap reconstruction. Design, Setting, and Participants: This retrospective cohort study of 733 patients was conducted at an academic tertiary care medical center. Head and neck oncologic procedures involving microvascular free flap reconstruction with available intraoperative data collected from January 1, 2000, to December 31, 2021, were included. Main Outcomes and Measures: Patient characteristics including demographic characteristics and comorbid conditions, operative variables, length of stay, and postoperative outcomes were measured. Descriptive statistics and effect size measures were performed to compare the 3 intraoperative surgical team approaches, specifically single surgeon, separate 2-team approach, and integrated 2-team approach; 1:1 nearest neighbor matching without caliper was performed to compare single- vs 2-team and separate and integrated 2-team approaches. Effect size measures including Cramer V for dichotomous variables, the Kendall W coefficient of concordance for ordinal variables, and η2 for continuous variables were reported with 95% CIs to describe precision. Results: Among 733 cases, there were no clinically significant differences in patient demographic characteristics, clinicopathologic characteristics, and choice of free flap reconstruction based on intraoperative surgical team approach. The mean (SD) age was 58.7 (12.4) years, and 514 were male (70.1%). In terms of operative and postoperative variables, there was a difference in operative times and intraoperative fluid requirements among the 3 different techniques, with the integrated 2-team approach demonstrating a mean reduction in operative time of approximately 2 hours (η2 = 0.871; 95% CI, 0.852-0.887; mean [SD] operative time = 541 [191] minutes for the single-surgeon approach, 399 [175] minutes for the integrated 2-team approach, and 537 [200] minutes for the separate 2-team approach) and lower fluid requirements of greater than 1 L (η2 = 0.790; 95% CI, 0.762-0.817). In both unadjusted analyses and propensity score matching, there were no clinically significant differences in terms of ischemia time, use of pressors, postoperative complications (including free flap failure, number of return trips to the operating room, length of stay, or 30-day readmission) based on intraoperative team approach. Conclusions and Relevance: Findings suggest that the integrated 2-team surgical approach for complex head and neck microvascular reconstruction can be used to safely decrease operative time, with no difference in postoperative outcomes.

Hypoglossal nerve stimulation (HGNS) has emerged as a successful surgical treatment strategy for moderate to severe obstructive sleep apnea in patients failing first-line positive airway pressure therapy. HGNS explantation due to adverse events such as pain and infection is rare and has yet to be well described. Here, our correspondence describes the first case series of patients who have undergone explantation of the Inspire HGNS system. Five patients were identified who underwent HGNS explantation. Three patients underwent explantation due to magnetic resonance imaging (MRI) incompatibility. One patient underwent explantation due to poor cosmesis. One patient underwent explantation due to surgical site infection. Average operative explant time was 163 minutes. MRI incompatibility, poor cosmesis, and device-related infection are reasons for HGNS explantation. Future need for MRI or chest wall surgery should be considered in patients being evaluated for HGNS implants.
RESUMEN
The aging US population requires an increasing volume of otolaryngology-head and neck surgery services, yet the otolaryngologist physician workforce remains static. Advanced practice providers (APPs), including physician assistants and nurse practitioners, improve access across the continuum of primary and subspecialty health care. The rapid growth of APP service is evidenced by a 51% increase in APP Medicare billing for otolaryngology procedures over 5 years. APPs increasingly participate in delivering otolaryngology care; however, reaping the benefits of enhanced patient access and modernizing care delivery is predicated on successful integration of APPs into practices. Few data are available on how best to incorporate APPs into team-based models or how to restructure practices to allow graduated responsibility that supports autonomy and effective teamwork. We compare national APP and physician workforce trends in otolaryngology, consider approaches to optimizing efficiency by integrating APPs, and identify opportunities for improving data collection and practice.

Candidacy evaluation for hypoglossal nerve stimulation (HGNS) is resource intensive. This proof-of-concept study investigates use of in-office volitional snore during flexible laryngoscopy as an efficient, cost-effective screening tool for HGNS evaluation. Adults with moderate to severe obstructive sleep apnea that failed continuous positive airway pressure treatment (n = 41) underwent evaluation for HGNS from 2018 to 2019. Volitional snore and drug-induced sleep endoscopy (DISE) data were collected and scored by VOTE classification (velum/palate, oropharynx, tongue base, epiglottis). A chi-square test of independence was performed that demonstrated a significant relationship between volitional snore and DISE (χ2 = 4.39, P = .036) for velum collapse pattern. Sensitivity and specificity of volitional snore for detecting velum collapse pattern were 93.6% (95% CI, 75.6%-99.2%) and 40% (95% CI, 12.2%-73.8%), respectively, illustrating its utility in screening for HGNS. Patients who demonstrate anterior-posterior velum collapse on volitional snore may be excellent candidates for confirmatory DISE at the time of HGNS implantation.

Human papillomavirus (HPV) related oropharyngeal squamous cell carcinoma (OPSCC) is associated with improved outcomes compared to non-virally mediated disease. Clinical trials are actively investigating de-escalation strategies to maintain excellent survival outcomes while minimizing toxicity. Delivery of effective precision medicine-based therapeutic approaches are strengthened by the identification of biomarkers to predict treatment response. Plasma circulating tumor (ct) DNA is the most studied liquid biomarker in head and neck cancer and has shown great promise in the ability to determine treatment response and monitor for disease recurrence. In this review, we examine the emerging evidence for ctDNA as a biomarker in HPV related OPSCC and discuss opportunities for future investigation and integration into clinical practice.

Importance: In an era of increasing health care expenditure, reduction of redundant head and neck surgical instrumentation may minimize waste. Objective: To (1) optimize head and neck surgical instrument trays at a single large academic tertiary care center and (2) identify associated direct cost savings. Design, Setting, and Participants: This prospective quality improvement initiative was conducted at an academic tertiary care medical center from July 2017 through July 2021. Participants were a multidisciplinary surgical quality team consisting of head and neck surgeons, operating room nurses, surgical technicians, and supply chain analysts. Main Outcomes and Measures: The 4 primary surgical instrument trays (major otolaryngology [Oto], Oto plastics, direct laryngoscopy, and microdirect laryngoscopy) used in all head and neck procedures were reviewed by 10 head and neck surgical faculty with detailed case observation of instrument utilization performed by trained operating room nurses and surgical technologists. Instruments used in less than 40% of cases were excluded from surgical trays, and novel instrument trays were established based on faculty feedback and utilization. Data on instrument processing, utilization, and associated institutional direct costs were prospectively collected over a 3-year period. The primary outcome measure was change in operating room direct costs. Surgeon satisfaction with the quality improvement intervention was the secondary outcome. Direct cost savings were identified as a function of surgical volume, labor and supply costs, and instrument depreciation. Results: More than 1500 eligible surgical cases were reviewed during the preintervention period. Of the 149 instruments in the major Oto tray, only 118 (79%) instruments were used in more than 40% of cases. There were 58 (49%) and 32 (21%) instruments in this tray that were used in more than 40% of neck dissections and sentinel lymph node biopsies, respectively. Resulting intervention included development of a streamlined major Oto tray with 118 instruments and novel neck dissection and sentinel lymph node biopsy trays. Similar processes were applied to the remaining head and neck trays, with a total of 257 instruments removed. Over a 3-year postintervention period, streamlined surgical trays were used 9284 times with direct cost savings of $228â¯338 (95% CI, $227â¯817-$228â¯854). Overall surgeon satisfaction with the optimized head and neck surgical trays was 100%. Conclusions and Relevance: In this quality improvement study, surgeon-led elimination of redundant or rarely used instruments from surgical instrument trays was associated with reduced operating room direct costs while maintaining stakeholder satisfaction.

Importance: Although routine postoperative care for microvascular free flap reconstruction typically involves admission to the intensive care unit (ICU), few studies have investigated the effect of postoperative care setting on clinical outcomes and institution cost. Objectives: To determine the value of non-ICU-based postoperative management for free tissue transfer for head and neck surgery, in terms of clinical outcomes and cost-effectiveness. Design, Setting, and Participants: This is a retrospective cohort study of two groups of adults who underwent vascularized free tissue transfer from October 2013 to October 2017 at an academic tertiary care center and community-based hospital, respectively. Postoperative management differed such that the first group recovered in a protocol-driven non-ICU setting and the second group was cared for in a planned admission to the ICU. A single surgeon performed all tissue harvest and reconstruction at both centers. Main Outcomes and Measures: Descriptive statistics and cost analyses were performed to compare clinical outcomes and total surgical and downstream direct cost to the institution between the two patient groups. Categorical variables were compared using χ2 test where appropriate. Results: Among a total of 338 patients who underwent microvascular free flap reconstruction for head and neck surgical defects, there was no significant difference in patient characteristics such as demographics, comorbidities, history of surgical resection, prior free flap, and locoradiation between the postoperative ICU cohort (n = 146) and protocol-driven non-ICU cohort (n = 192). There were 16 patients in the non-ICU group who spent >3 days in the ICU postoperatively secondary to patient comorbidities and patient care priorities. Still, the average ICU length of stay was 7 days (interquartile range [IQR] 6-9 days) for the planned ICU cohort versus 1 day (IQR 0-1) for the non-ICU group (p < 0.00001). There was no difference in operative variables such as donor site, case length, or total length of stay, and postoperative management in the ICU versus non-ICU setting resulted in no significant difference in terms of flap survival, reoperation, readmission, and postoperative complications. However, average cost of care was significantly higher for patients who received ICU-based care versus non-ICU postoperative care. Specifically, room and board were 239% more costly for the planned ICU care group than the non-ICU setting (p < 0.00001). Conclusions and Relevance: This study demonstrates that postoperative management after vascularized free tissue transfer in a non-ICU setting is equivalent to standard ICU-based management, in terms of clinical outcomes, while being less costly.

OBJECTIVES: To optimize prophylactic antibiotic timing and delivery across all surgeries performed at a single large pediatric tertiary care center. METHODS: A multidisciplinary surgical quality team conducted a quality improvement initiative from July 2015 to December 2019 by using the A3 problem-solving method to identify and evaluate interventions for appropriate antibiotic administration. The primary outcome measure was the percentage of surgical encounters for pediatric patients with appropriate timing of antibiotic administration before surgical incision. Surgical site infection rates was the secondary outcome. Intervention effectiveness was assessed by using statistical process control. RESULTS: A total of 32 192 eligible surgical cases for pediatric patients were completed during the study period. Identified barriers to timely perioperative antibiotic administration included failure to order antibiotics before the surgical date and lack of antibiotic availability in the operating room at the time of administration. Resulting sequential interventions included updating institutional guidelines to reflect procedure-specific antibiotic choices and clarifying timing of administration to optimize pharmacokinetics, creating a hard-stop antibiotic order within electronic health record case requests, optimizing pharmacy and nursing workflow, and implementing an automatic antibiotic prophylaxis timer in the operating room. Administration of prophylactic antibiotics during the recommended preincision time window significantly improved; the correct timing was recorded in 38.6% of preintervention cases versus 94.0% at the conclusion of rollout of the sequential interventions (P < .001). Surgical site infection rates remained stable. CONCLUSIONS: Here we demonstrate utility of the A3 problem-solving schematic to successfully optimize prophylactic antibiotic timing and delivery in the surgical setting for pediatric patients by implementing systems-based interventions.

OBJECTIVES: There is limited evidence regarding use of routine perioperative antibiotics for pediatric otolaryngologic procedures. The objectives of this quality improvement study were (1) to characterize the otolaryngology case mix for which antibiotics were delivered and (2) determine the percentage of surgical encounters with appropriate timing of antibiotic administration. METHODS: Pediatric otolaryngology procedures meeting criteria from 2015 to 2019 were evaluated as a component of an institution-wide pediatric surgical antibiotic prophylaxis study using A3 problem solving to identify and roll out interventions for appropriate antibiotic administration. Descriptive statistical analysis of the interrupted time-series data was used to describe the otolaryngology case mix for which antibiotics were delivered. The primary outcome measure was percentage of surgical encounters with appropriate timing of antibiotic administration in minutes relative to incision. RESULTS: In total, 1520 pediatric otolaryngology procedures with perioperative antibiotic delivery were performed from July 2015 to September 2019. While surgical site infection number (n = 2/year) was stable, administration of timely prophylactic antibiotics significantly improved: 27.5% of cases per month at baseline and 86.9% at the conclusion of the rollout of the sequential interventions (P < .001). DISCUSSION: Given the exceedingly low infection rate of clean otolaryngology surgery, there is limited evidence in favor of perioperative antibiotics for the majority of procedures. Prophylactic antibiotics were most commonly used in otologic surgery involving cochlear implantation or in the setting of draining ears or cholesteatoma and in clean-contaminated head and neck surgery cases. IMPLICATIONS FOR PRACTICE: Iterative continuous performance improvement can optimize evidence-based delivery of preoperative prophylactic antibiotics. Additional interventions to ensure antimicrobial stewardship in pediatric otolaryngology are indicated.
