RESUMO

BACKGROUND: ChatGPT is among the most popular large language models (LLMs), exhibiting proficiency in various standardized tests, including multiple-choice medical board examinations. However, its performance on otolaryngology-head and neck surgery (OHNS) certification examinations and open-ended medical board certification examinations has not been reported. OBJECTIVE: We aimed to evaluate the performance of ChatGPT on OHNS board examinations and propose a novel method to assess an AI model's performance on open-ended medical board examination questions. METHODS: Twenty-one open-ended questions were adopted from the Royal College of Physicians and Surgeons of Canada's sample examination to query ChatGPT on April 11, 2023, with and without prompts. A new model, named Concordance, Validity, Safety, Competency (CVSC), was developed to evaluate its performance. RESULTS: In an open-ended question assessment, ChatGPT achieved a passing mark (an average of 75% across 3 trials) in the attempts and demonstrated higher accuracy with prompts. The model demonstrated high concordance (92.06%) and satisfactory validity. While demonstrating considerable consistency in regenerating answers, it often provided only partially correct responses. Notably, concerning features such as hallucinations and self-conflicting answers were observed. CONCLUSIONS: ChatGPT achieved a passing score in the sample examination and demonstrated the potential to pass the OHNS certification examination of the Royal College of Physicians and Surgeons of Canada. Some concerns remain due to its hallucinations, which could pose risks to patient safety. Further adjustments are necessary to yield safer and more accurate answers for clinical implementation.

RESUMO

Immune checkpoint inhibition (ICI) is effective for replication-repair-deficient, high-grade gliomas (RRD-HGG). The clinical/biological impact of immune-directed approaches after failing ICI monotherapy is unknown. We performed an international study on 75 patients treated with anti-PD-1; 20 are progression free (median follow-up, 3.7 years). After second progression/recurrence (n = 55), continuing ICI-based salvage prolonged survival to 11.6 months (n = 38; P < 0.001), particularly for those with extreme mutation burden (P = 0.03). Delayed, sustained responses were observed, associated with changes in mutational spectra and the immune microenvironment. Response to reirradiation was explained by an absence of deleterious postradiation indel signatures (ID8). CTLA4 expression increased over time, and subsequent CTLA4 inhibition resulted in response/stable disease in 75%. RAS-MAPK-pathway inhibition led to the reinvigoration of peripheral immune and radiologic responses. Local (flare) and systemic immune adverse events were frequent (biallelic mismatch-repair deficiency > Lynch syndrome). We provide a mechanistic rationale for the sustained benefit in RRD-HGG from immune-directed/synergistic salvage therapies. Future approaches need to be tailored to patient and tumor biology. SIGNIFICANCE: Hypermutant RRD-HGG are susceptible to checkpoint inhibitors beyond initial progression, leading to improved survival when reirradiation and synergistic immune/targeted agents are added. This is driven by their unique biological and immune properties, which evolve over time. Future research should focus on combinatorial regimens that increase patient survival while limiting immune toxicity. This article is featured in Selected Articles from This Issue, p. 201.

RESUMO

Background: Primary central nervous system tumors are a leading cause of death and disability amongst pediatric cancer patients. Akron Children's Hospital published data in 2018 on response time for brain tumor diagnosis and implemented components of an established program to decrease diagnostic delays and thereby reduce tumor- and treatment-related morbidities. This study evaluates if there was an improvement in the total diagnostic interval (TDI, time from symptom onset to diagnosis) after provider education. During the study, the COVID-19 pandemic forced alterations in care delivery. The impact this had on the TDI was also assessed. Methods: A retrospective chart review was performed, and patients were separated into 2008-2017 (historical) and 2018-2021 (posteducation) groups to assess the effect of educational interventions on TDI. The posteducation cohort was analyzed separately to assess the impact of COVID-19 pandemic. Results: The 85 patients studied in the post-education group showed a median TDI of 31 days. Though not statistically significant (P = .939), this represents an 11-day decrease in median TDI compared to the historical group (42 days). In addition, the posteducation group showed an increase in the average number of healthcare provider visits (HCP, 2.4 historical to 3.2 posteducation, P = .009). The pre-COVID-19 group (median TDI 43.5 days) did not differ statistically from the post-COVID-19 group (30-day median TDI). Conclusion: The nonsignificant decrease in TDI and concurrent increase in HCP visits after implementation of education suggests a potential gap amongst providers in working-up primary CNS tumors. These results will influence expansion of education to further improve TDI.

RESUMO

BACKGROUND: Chronic rhinosinusitis with nasal polyposis (CRSwNP) often coexists with lower airway disease. With the overlap between upper and lower airway disease, optimal management of the upper airways is undertaken in conjunction with that of the lower airways. Biologic therapy with targeted activity within the Type 2 inflammatory pathway can improve the clinical signs and symptoms of both upper and lower airway diseases. Knowledge gaps nevertheless exist in how best to approach patient care as a whole. There have been sixteen randomized, double-blind, placebo-controlled trails performed for CRSwNP targeted components of the Type 2 inflammatory pathway, notably interleukin (IL)-4, IL-5 and IL-13, IL- 5R, IL-33, and immunoglobulin (Ig)E. This white paper considers the perspectives of experts in various disciplines such as rhinology, allergy, and respirology across Canada, all of whom have unique and valuable insights to contribute on how to best approach patients with upper airway disease from a multidisciplinary perspective. METHODS: A Delphi Method process was utilized involving three rounds of questionnaires in which the first two were completed individually online and the third was discussed on a virtual platform with all the panelists. A national multidisciplinary expert panel of 34 certified specialists was created, composed of 16 rhinologists, 7 allergists, and 11 respirologists who evaluated the 20 original statements on a scale of 1-9 and provided comments. All ratings were quantitively reviewed by mean, median, mode, range, standard deviation and inter-rater reliability. Consensus was defined by relative interrater reliability measures-kappa coefficient ([Formula: see text]) value > 0.61. RESULTS: After three rounds, a total of 22 statements achieved consensus. This white paper only contains the final agreed upon statements and clear rationale and support for the statements regarding the use of biologics in patients with upper airway disease. CONCLUSION: This white paper provides guidance to Canadian physicians on the use of biologic therapy for the management of upper airway disease from a multidisciplinary perspective, but the medical and surgical regimen should ultimately be individualized to the patient. As more biologics become available and additional trials are published we will provide updated versions of this white paper every few years.

RESUMO

BACKGROUND: Microlaryngoscopy is a basic technical skill in Oto-HNS. It is essential for residency programs to have a competency-based assessment tool to evaluate residents' performance of this procedure. An Objective Structured Assessment of Technical Skills (OSATS) is a procedure-specific assessment, which consists of the following: (a) Operation-Specific Checklist and (b) Global Rating Scale (GRS). OBJECTIVE: The objective of this study was to create an OSATS for adult microlaryngoscopy. METHODS: This was a prospective study, with an initial qualitative phase for OSATS development (Phase I), and a clinical pilot phase (Phase II). In Phase I, interviews were conducted with three laryngologists to establish a stepwise description of adult microlaryngoscopy and review a previously validated GRS for relevance to microlaryngoscopy. Responses were used to create a framework for the OSATS. The OSATS was then presented to Oto-HNS residents and laryngologists in an alternating fashion, for review of clarity and relevance. A pilot study was then performed to evaluate the resident performance of adult microlaryngoscopy. Multiple regression analysis was carried out to investigate whether training level, case complexity, and previous OSATS exposure could predict participant scores. RESULTS: Phase I of this study led to the creation of a 34-item OSATS. The pilot study (N = 28 procedures) revealed that training level was significantly correlated with increased OSATS scores. There was no statistically significant correlation between case complexity and resident scores. Assessors reported the perceived utility of the OSATS and intent for use in residency training. CONCLUSION: Application of the proposed OSATS will allow for competency-based assessment of the resident performance of microlaryngoscopy. LEVEL OF EVIDENCE: NA Laryngoscope, 133:2719-2724, 2023.

RESUMO

OBJECTIVES: Many experts feel that in the absence of well-defined goals for success, they have an easier time identifying failure. As success ought to not be defined only by absence of failure, we aimed to define optimal outcomes for endoscopic sinus surgery (ESS) in chronic rhinosinusitis (CRS) by obtaining expert surgeon perspectives. METHODS: A total of 12 surgeons participated in this targeted consultation. Face to face semi-structured interviews were performed with expert surgeons in the field of CRS and ESS. General impressions and personal definitions of acceptable operative success and optimal operative outcomes were compiled and summarized. RESULTS: According to an expert survey, patients' main objectives are an improvement in their chief complain, a general improvement in quality of life (QoL), and a better overall symptomatic control. The most important aspects of endoscopy for defining a successful intervention were an adequate mucus circulation, a healthy mucosa, minimal edema, and patency of all explored cavities or ostia. In the assessment of surgical outcomes, it was determined that both objective and patient reported data must be carefully examined, with more attention given to subjective outcomes. CONCLUSIONS: According to data gathered from a Canadian expert consultation, a definition of success must be based on both subjective data and nasal endoscopy. We propose to define an acceptable outcome as either a subjective improvement of at least the minimal clinically improvement difference of a validated patient reported outcome questionnaire, along with a satisfactory endoscopic result (1) or a complete subjective resolution with a sub-optimal endoscopy (2).

RESUMO

BACKGROUND: Existing research has primarily focused on weight as the outcome of interest for bariatric surgery; however, patients frequently report other lifestyle and interpersonal surgery motivations and goals. Understanding the spectrum of bariatric surgery goals and motivations has important implications for enhancing patient-centered care and surgery outcomes. OBJECTIVES: The current study characterized the nature of bariatric patient motivations and goals for surgery, described the extent to which motivations matched goals, and examined whether men and women differed in the specific motivations/goals described. SETTING: Teaching hospital, United States METHODS: Data were obtained via retrospective chart review of bariatric patient responses to the clinic's standard open-ended questions about motivations and goals for bariatric surgery. A mixed method approach was used, including content analysis, to identify themes and χ2/t test analyses to test gender differences. RESULTS: Surgery motivations and outcome goals were reflected by 8 overarching and overlapping themes. The most common motivations were related to general health and quality of life. The most common goals were to improve health/longevity and mobility. Over a quarter of patients showed no overlap between motivations and goals. Few gender differences were observed. CONCLUSION: Findings underscore the importance of goals beyond weight loss, as well as the utility of helping patients shape their goals in accordance with goal-setting theories.

RESUMO

BACKGROUND: Craniospinal irradiation (CSI) is part of the treatment of central nervous system (CNS) tumors and is associated with cardiovascular disease in adults. Global myocardial strain analysis including longitudinal peak systolic strain (GLS), circumferential peak systolic strain (GCS), and radial peak systolic strain (GRS) can reveal subclinical cardiac dysfunction. METHODS: Retrospective, single-center study in patients managed with CSI vs. age-matched controls. Clinical data and echocardiography, including myocardial strain analysis, were collected at early (< 12 months) and late (≥ 12 months) time points after completion of CSI. RESULTS: Echocardiograms were available at 20 early and 34 late time points. Patients at the late time point were older (21.7 ± 10.4 vs. 13.3 ± 9.6 years) and further out from CSI (13.1 ± 8.8 vs. 0.2 ± 0.3 years). Standard echocardiographic parameters were normal for both groups. For early, CSI vs. control: GLS was - 16.8 ± 3.6% vs. -21.3 ± 4.0% (p = 0.0002), GCS was - 22.5 ± 5.2% vs. -21.3 ± 3.4% (p = 0.28), and GRS was 21.8 ± 11.0% vs. 26.9 ± 7.7% (p = 0.07). For late, CSI vs. control: GLS was - 16.2 ± 5.4% vs. -21.6 ± 3.7% (p < 0.0001), GCS was - 20.9 ± 6.8% vs. -21.9 ± 3.5% (p = 0.42), and GRS was 22.5 ± 10.0% vs. 27.3 ± 8.3% (p = 0.03). Radiation type (proton vs. photon), and radiation dose (< 30 Gy vs. ≥ 30 Gy) did not impact any parameter, although numbers were small. CONCLUSIONS: Subclinical cardiac systolic dysfunction by GLS is present both early and late after CSI. These results argue for future studies to determine baseline cardiovascular status and the need for early initiation of longitudinal follow-up post CSI.

RESUMO

Recent discoveries have provided valuable insight into the genomic landscape of pediatric low-grade gliomas (LGGs) at diagnosis, facilitating molecularly targeted treatment. However, little is known about their temporal and therapy-related genomic heterogeneity. An adequate understanding of the evolution of pediatric LGGs' genomic profiles over time is critically important in guiding decisions about targeted therapeutics and diagnostic biopsy at recurrence. Fluorescence in situ hybridization, mutation-specific immunohistochemistry, and/or targeted sequencing were performed on paired tumor samples from primary diagnostic and subsequent surgeries. Ninety-four tumor samples from 45 patients (41 with two specimens, four with three specimens) from three institutions underwent testing. Conservation of BRAF fusion, BRAFV600E mutation, and FGFR1 rearrangement status was observed in 100%, 98%, and 96% of paired specimens, respectively. No loss or gain of IDH1 mutations or NTRK2, MYB, or MYBL1 rearrangements were detected over time. Histologic diagnosis remained the same in all tumors, with no acquired H3K27M mutations or malignant transformation. Changes in CDKN2A deletion status at recurrence occurred in 11 patients (42%), with acquisition of hemizygous CDKN2A deletion in seven and loss in four. Shorter time to progression and shorter time to subsequent surgery were observed among patients with acquired CDKN2A deletions compared to patients without acquisition of this alteration [median time to progression: 5.5 versus 16.0 months (p = 0.048); median time to next surgery: 17.0 months versus 29.0 months (p = 0.031)]. Most targetable genetic aberrations in pediatric LGGs, including BRAF alterations, are conserved at recurrence and following chemotherapy or irradiation. However, changes in CDKN2A deletion status over time were demonstrated. Acquisition of CDKN2A deletion may define a higher risk subgroup of pediatric LGGs with a poorer prognosis. Given the potential for targeted therapies for tumors harboring CDKN2A deletions, biopsy at recurrence may be indicated in certain patients, especially those with rapid progression.

RESUMO

INTRODUCTION: Low-grade glioma (LGG) represent the most common pediatric central nervous system tumor. When total surgical resection is not feasible, chemotherapy is first-line therapy in children. Multiple pediatric LGG chemotherapy regimens have been investigated with variable 2-year event free survival (EFS) rates of 39-69%. To date, treatment of pediatric LGG with a carboplatin and vinblastine (C/VBL) chemotherapy regimen has only been evaluated in a phase 1 dose-finding study. METHODS: A retrospective review of pediatric patients with LGG who were treated with C/VBL at Children's Hospital of Colorado or Akron Children's Hospital from 2011 to 2017 was conducted. Data collected included patient demographics, tumor location, disease response, neurofibromatosis 1 (NF1) status, therapy duration and toxicities. Response to therapy was determined by objective findings on imaging and treating physicians' evaluation. RESULTS: Forty-six patients were identified for analysis, all of whom were chemotherapy-naive. Only five patients treated in this cohort had NF1. BRAF fusion was identified in 65% (22/34) of tested tumors. Best therapy response was partial response in nine patients and stable disease in twenty-five patients. Twelve patients had progressive disease. One-year, 3-year, and 5-year EFS probabilities for all patients were 69.6%, 39.4%, and 34.5%, respectively. Nine patients had admissions for febrile neutropenia and seven patients experienced one delay in chemotherapy due to neutropenia. Only two patients had to discontinue this chemotherapy regimen because of treatment-related toxicities [carboplatin allergy (n = 1) and vinblastine neuropathy (n = 1)]. CONCLUSION: C/VBL achieves similar EFS rates to other single-agent and combination cytotoxic chemotherapy regimens for pediatric LGG with manageable toxicities.

RESUMO

PURPOSE: With the increasing use of imaging, there has been an increase in the number of incidentally found brain lesions in pediatric patients resulting in a treatment dilemma for physicians and emotional strain for patients and families. Adult studies support initial surveillance of incidentally found low grade appearing lesions as the most appropriate approach. The aim of this study was to evaluate incidental lesions in the pediatric population and propose an initial treatment algorithm for such lesions. METHODS: Pediatric records were retrospectively reviewed at Johns Hopkins All Children's Hospital for incidentally found brain tumors between 2000 and 2017. Demographic data, presenting symptoms, treatment approach, and outcomes were reviewed for 55 patients, age 0-18. RESULTS: Of the 55 patients included in the study, 14 underwent surgical resection, 3 underwent biopsy, and 38 with benign imaging characteristics at presentation were monitored with radiology alone. Only one patient, out of the 17 that underwent resection or biopsy, had pathology consistent with a high grade glioma. Of the patients monitored radiographically 10 total patients showed an increase in the overall size of the lesion; however after a median follow up of 34.2 months only 2 increased to a degree that required surgical intervention. CONCLUSIONS: The majority of incidentally found brain lesions with benign imaging characteristics at presentation may be managed conservatively. Surveillance is an important part of the initial management of incidental lesions in the pediatric population, but careful scrutiny must be paid to the potential for higher grade lesions or malignant transformation.

RESUMO

OBJECTIVE: Aspirin exacerbated respiratory disease (AERD) patients are challenging to manage with sinonasal and pulmonary symptoms refractory to maximal medical and surgical therapies. Our objective was to comprehensively examine objective and validated, disease-specific subjective sinonasal and pulmonary outcomes of aspirin (ASA) desensitization therapy in this patient population. METHODS: Prospective cohort study at an academic tertiary center. AERD patients with a history of chronic rhinosinusitis with nasal polyposis (CRSwNP), prior diagnosis of asthma, and a history of ASA sensitivity were eligible for inclusion. Patients underwent ASA desensitization using an established institutional protocol and continued on a 650mg twice daily maintenance dose. Baseline Sinonasal Outcome Test (SNOT-22) and Asthma Control Questionnaire (ACQ) responses, acoustic rhinometry, peak flow readings, and endoscopic scoring of nasal polyps were recorded prior to desensitization and after 6months of maintenance therapy. RESULTS: Twelve patients were recruited for participation and underwent desensitization. Eight patients continued maintenance therapy and follow up at 6months. Prior to desensitization, patients reported bothersome sinonasal symptoms with a median SNOT-22 score of 30.0±34.5 (interquartile range (IQR)). There was significant improvement after 6months of maintenance therapy to a median SNOT-22 score of 18.5±17.3 (p=0.025, Wilcoxon signed rank test). Acoustic rhinometry, endoscopic scores, ACQ and forced expiratory volume values remained stable at 6months. CONCLUSIONS: AERD patients may benefit from ASA desensitization with subjective sinonasal symptom improvement at 6months and stable asthma and objective sinonasal measures. Further discussion is needed in the otolaryngology community regarding ASA desensitization in AERD management.

RESUMO

BACKGROUND: Chronic rhinosinusitis (CRS) affects up to 16% of the population. When medical treatment fails, endoscopic sinus surgery (ESS) is considered. The value of resecting the middle turbinate to optimize surgical outcomes has been hypothesized but remains controversial and unproven. Whether the middle turbinate should be left in place or resected is controversial. Our objective is to determine if middle turbinectomy improves objective surgical outcomes after ESS. METHODS: Sixteen patients (15 men, 15 primary surgery) undergoing bilateral complete ESS for CRS with nasal polyposis were recruited. Nasal cavities were randomized so that middle turbinectomy was performed on one side while the middle turbinate was preserved on the other. Each participant acted as their own control. Nasal cavities were compared using Perioperative Sinus Endoscopy (POSE) and Lund-Kennedy (LKES) scores pre-operatively, and at 1, 3 and 6 months after ESS. Results were analyzed using Wilcoxon signed-rank test. RESULTS: Pre-operatively, the POSE (12.4 ± 2.9 vs 12.8 ± 2.6, p = 0.33, for the preserved side and the resected side, respectively) and LKES (5.0 ± 1.0 vs 4.8 ± 1.2, p = 0.33) scores were similar between sides. During follow up, resection was associated with more crusting at 1 month following ESS (1.0 ± 0.7 vs 0.4 ± 0.6, p = 0.02). There was a small, but statistically significant, difference between the nasal cavities at 3 months, where the resected side showed better endoscopic appearance (2.0 ± 2.2 vs 3.4 ± 2.8, p = 0.01). No difference was found at 6 months. Frontal sinus scores were similar between sides at 6 months (0.7 ± 0.5 vs 0.7 ± 0.5, p = 1.00). CONCLUSION: Our results show no sustained objective endoscopic benefit of routine middle turbinectomy, at least within the first six postoperative months, in patients undergoing primary ESS for CRS with polyposis.

RESUMO

BACKGROUND: Bleeding during endoscopic sinus surgery (ESS) can impair visualization and delay surgical progress. The role that anesthetic technique may have on the quality of surgical field during ESS has been previously studied. However, meta-analyses have deemed the current literature inconclusive and lacking methodological consistency. This study was designed with these critiques in mind to assess the effect of total intravenous anesthesia (TIVA) vs inhaled anesthetic on the quality of the surgical field during ESS. METHODS: This study was a double-blind, randomized, controlled trial of 30 patients of American Society of Anesthesiologists (ASA) class 1 or 2 undergoing bilateral ESS for the primary diagnosis of chronic rhinosinusitis. In addition to standard techniques to minimize blood loss, study patients were randomized to maintenance anesthesia with intravenous propofol or inhaled desflurane. Anesthetic depth was standardized using bispectral index (BIS). The primary outcome measured was the Wormald grading scale to assess the endoscopic surgical field. RESULTS: The use of TIVA was associated with a statistically significant reduction in mean Wormald score compared to desflurane (4.21 vs 5.53, p = 0.024). Mean Boezaart score was also lower in the TIVA arm (2.18 vs 2.76, p = 0.034). Experimental groups were homogeneous in all compared baseline characteristics. Secondary outcomes including surgical duration, time to extubation, and estimated blood loss were not found to be statistically significant between experimental groups. CONCLUSION: Even with all other factors implemented to optimize the surgical field, utilization of TIVA vs inhaled anesthetic still resulted in a statistically significant improvement in surgical field during ESS.

RESUMO

BACKGROUND: Chronic rhinosinusitis (CRS) has been identified as a high-priority disease category for quality improvement. To this end, this study aimed to develop CRS-specific quality indicators (QIs) to evaluate diagnosis and management that relieves patient discomfort, improves quality of life, and prevents complications. METHODS: A guideline-based approach, proposed in 2012 by Kötter et al. was used to develop QIs for CRS. Candidate indicators (CIs) were extracted from 3 practice guidelines and 1 international consensus statement on the diagnosis and management of CRS. Guidelines were evaluated using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool. Each CI and its supporting evidence was summarized and reviewed by an expert panel based on validity, reliability, and feasibility of measurement. Final QIs were selected from CIs utilizing the modified RAND Corporation-University of California, Los Angeles (RAND/UCLA) appropriateness methodology. RESULTS: Thirty-nine CIs were identified after literature review and evaluated by our panel. Of these, 9 CIs reached consensus as being appropriate QIs, with 4 requiring additional discussion. After a second round of evaluations, the panel selected 9 QIs as appropriate measures of high-quality care. CONCLUSION: This study proposes 9 QIs for the diagnosis and management of patients with CRS. These QIs can serve multiple purposes, including documenting the quality of care; comparing institutions and providers; prioritizing quality improvement initiatives; supporting accountability, regulation, and accreditation; and determining pay-for-performance initiatives.

RESUMO

BACKGROUND: The goal of this study was to develop and evaluate the impact of an aviation-style challenge and response sinus surgery-specific checklist on potential safety and equipment issues during sinus surgery at a tertiary academic health center. The secondary goal was to assess the potential impact of use of the checklist on surgical times during, before, and after surgery. This initiative is designed to be utilized in conjunction with the "standard" World Health Organization (WHO) surgical checklist. Although endoscopic sinus surgery is generally considered a safe procedure, avoidable complications and potential safety concerns continue to occur. The WHO surgical checklist does not directly address certain surgery-specific issues, which may be of particular relevance for endoscopic sinus surgery. METHODS: This prospective observational pilot study monitored compliance with and compared the occurrence of safety and equipment issues before and after implementation of the checklist. Forty-seven consecutive endoscopic surgeries were audited; the first 8 without the checklist and the following 39 with the checklist. The checklist was compiled by evaluating the patient journey, utilizing the available literature, expert consensus, and finally reevaluation with audit type cases. The final checklist was developed with all relevant stakeholders involved in a Delphi method. RESULTS: Implementing this specific surgical checklist in 39 cases at our institution, allowed us to identify and rectify 35 separate instances of potentially unsafe, improper or inefficient preoperative setup. These incidents included issues with labeling of topical vasoconstrictor or injectable anesthetics (3, 7.7%) and availability, function and/or position of video monitors (2, 5.1%), endoscope (6, 15.4%), microdebrider (6, 15.4%), bipolar cautery (6, 15.4%), and suctions (12, 30.8%). CONCLUSION: The design and integration of this checklist for endoscopic sinus surgery, has helped improve efficiency and patient safety in the operating room setting.

RESUMO

Limited health literacy is a common but often unrecognized problem associated with poor health outcomes. Well-validated screening tools are available to identify and provide the opportunity to intervene for at-risk patients in a resource-efficient manner. This is a multimethod study describing the implementation of a hospital-wide routine health literacy assessment at an academic medical center initiated by nurses in April 2014 and applied to all adult inpatients. Results were documented in the electronic health record, which then generated care plans and alerts for patients who screened positive. A nursing survey showed good ease of use and adequate patient acceptance of the screening process. Six months after hospital-wide implementation, retrospective chart abstraction of 1,455 patients showed that 84% were screened. We conclude that a routine health literacy assessment can be feasibly and successfully implemented into the nursing workflow and electronic health record of a major academic medical center.

RESUMO

BACKGROUND: Otolaryngology-Head and Neck surgery resident physicians (OHNSR) have a high prevalence of burnout, job dissatisfaction and stress as shown within the literature. Formal mentorship programs (FMP) have a proven track record of enhancing professional development and academic success. More importantly FMP have an overall positive impact on residents and assist in improving job satisfaction. The purpose of the study is to determine the effects of a FMP on the well-being of OHNSR. METHODS: A FMP was established and all OHNSR participation was voluntary. Eight OHNSR participated in the program. Perceived Stress Survey (PSS) and the Maslach Burnout Inventory (MBI) were administered at baseline and then at 3, 6, 9, and 12 month intervals. World Health Quality of Life-Bref Questionnaire (WH-QOL) was administered at baseline and at 12 months. RESULTS: Baseline statistics found a significant burden of stress and burnout with an average PSS of 18.5 with a high MBI of 47.6, 50.6, and 16.5 for the emotional, depersonalization, and personal achievement domains respectively. Quality of life was also found to be low with a WH-QOL score of 71.9. After implementation of the FMP, PSS was reduced to 14.5 at 3 months (p = 0.174) and a statistically significant lower value of 7.9 at 12 months (p = 0.001). Participants were also found to have lower emotional scores (14.9, p < 0.0001), levels of depersonalization (20.1, p < 0.0001), and higher personal achievement (42.5, p < 0.0001) on MBI testing at 12 months. Overall quality values using the WH-QOL was also found to be significantly improved (37.5, P = 0.003) with statistically significant lower scores for the physical health (33.9, p = 0.003), psychological (41.1, p = 0.001), social relationship (46.9, p = 0.019), and environment (53.5, p = 0.012) domains. CONCLUSION: This is the first study to show that FMP can potentially alleviate high levels of stress and burnout within a surgical residency program and achieve higher levels of personal satisfaction as well as overall quality of life.

RESUMO

BACKGROUND: Initial descriptions of endoscopic approaches to the sella and pituitary involved resecting the middle turbinate (MT) to help improve access and visualization. Modifications of these procedures to preserve the MT have since been described, one rationale being to reduce the incidence of frontal sinusitis. The objective of this study was to establish the incidence of postoperative frontal sinusitis in MT sparing (MTsp) and MT sacrificing (MTsc) approaches to the sella. OBJECTIVE: A retrospective cohort study that compared radiographic evidence of frontal rhinosinusitis or frontal recess obstruction after skull base surgery in patients who underwent MTsc and MTsp endonasal approaches to the sella. METHODS: Consecutive retrospective review of pre- and postoperative magnetic resonance imaging from two institutions in geographic proximity but with different approaches to the sella. Mucosal thickening in the frontal sinus was measured and graded by a radiologist blinded to patient cohorts. RESULTS: Seventy-five patients, based on sample size calculations, were included at each site. Baseline demographics and indications for surgery were not significantly different between the groups. No difference was seen between the groups in the overall grade of radiographic frontal sinusitis seen on postoperative imaging. A total of 8 patients (10%) in the MTsc group had measured mucosal thickening, which was increased from their preoperative scan versus 15 in the MTsp group (20%) (p = 0.10). New mucosal thickening of >1 mm was found in three patients in the MTsc group and eight patients in the MTsp group (p = 0.21); the only patient with postoperative complete frontal sinus opacification was in the MTsp group. CONCLUSIONS: The choice of MTsc versus MTsp in endonasal endoscopic approach to the sella does not seem to make a difference in the incidence of postoperative radiographic frontal sinusitis.

RESUMO

BACKGROUND: The use of endoscopic endonasal approaches to the anterior skull base has dramatically expanded in recent years, with clinical endpoints and complication rates that compare favorably to traditional approaches. The impact of the endoscopic approach on sinonasal function has been less rigorously evaluated. The purpose of this study was to systematically analyze the literature evaluating objective sinonasal outcomes in endoscopic anterior skull-base surgery, and provide evidence-based recommendations. METHODS: A systematic review of the literature was performed based on a published guideline for developing an evidence-based review with recommendations. Objective sinonasal outcomes included were olfaction, mucociliary clearance, and nasal airflow. RESULTS: Ten articles were identified addressing objective olfactory outcomes: 2 randomized controlled trials; 6 cohort studies; and 2 retrospective case series. One cohort study investigating mucociliary clearance was identified. Six studies reporting postoperative endoscopic outcomes were identified. CONCLUSION: Based on the available evidence, nasoseptal flap (NSF) elevation with or without use in reconstruction likely leads to impairment in objective olfactory function. Endoscopic sellar and parasellar surgery without the elevation of an NSF may lead to a transient reduction in olfactory function. In the absence of a high a priori risk of cerebrospinal fluid (CSF) leak, it is an option to avoid routine NSF elevation in sellar and parasellar procedures, with preservation of at least 1 vascular pedicle during the approach. Monopolar electrocautery for mucosal incisions may increase the risk of olfactory impairment. If an NSF is used, donor site defect reconstruction may be considered.
