A Novel Interdisciplinary Iterative Approach for Optimizing the Electronic Health Record to Improve Perioperative Efficiency.

OBJECTIVE: We present a holistic perioperative optimization approach led by a CI team with the goal to optimize the workflow within our EHR, improve operative room metrics and user satisfaction. SUMMARY OF BACKGROUND DATA: The EHR has become integral to perioperative care. Many approaches are utilized to improve performance including systems-based approaches, process redesign, lean methodology, checklists, root cause analysis, and parallel processing. Although most reports describe strategies improving day or surgery productivity, few include perioperative interventions to improve efficiencies. METHODS: An interdisciplinary CI team consisting of clinicians, informatics specialists, and analysts spent 6 weeks assessing users and optimizing all perioperative areas (scheduling, day of surgery, postop discharge/admission). Elbow-to-elbow retraining and simultaneous content development was performed utilizing an Agile workflow process optimization with the Scrum framework. This iterative approach averaged 1 week from build to change implementation. Pre/post optimization surveys were sent. RESULTS: Two hundred forty-two perioperative enhancements were completed. While most impacted documentation, all areas were enhanced including billing, reporting, registration, device integration, scheduling, central supply, and so on. FCOTS improved from <70% to >85% and total delay was halved. These parameters were consistently sustained for over 1 year after the 6-week optimization. While only 5% of pre-optimization users agreed to proficiency in the EHR system, this improved to 70% post-optimization. Furthermore, EHR confidence and acceptance improved from 40% to 90%. CONCLUSIONS: To improve workflow efficiency, all who contribute to the perioperative process must be assessed. This IT driven initiative resulted in improved FCOTS, perioperative workflows, and user satisfaction.

Effect of greater palatine canal injection on estimated blood loss during endoscopic sinus surgery.

PURPOSE: We compare estimated blood loss (EBL) during endoscopic sinus surgery (ESS) between patients receiving transoral greater palatine canal (GPC) and transnasal infiltration (combined group) to patients receiving only transnasal infiltration (control group). CT stage, endoscopic stage, revision surgery, presence of polyps, degree of resident involvement, and operative time (OT) are also evaluated. METHODS: Injection with 1% lidocaine with 1:100,000 epinephrine was performed through the GPC and transnasally in the "combined" study group (20 patients) and only transnasally in the control group (22 patients). Charts, operative reports, and CT scans were reviewed and demographic data as well as pertinent information collected. Data analysis was performed using SPSS Version 16 (SPSS Inc., Chicago, Illinois). RESULTS: Twelve females and 8 males underwent combined injections and 16 males and 6 females received transnasal injections only. Average ratio of EBL to OT was 2.9 mL/min for the combined group and 4.1 mL/min for the control group (p=0.05). Presence of polyps and revision surgery lead to a statistically significantly higher EBL (p<0.05). Increased EBL and OT were noted with higher endoscopic and CT stages. No complications were reported. CONCLUSIONS: Increased endoscopic and CT stages, presence of polyps, and revision surgery may all lead to greater EBL in ESS. Although there was a trend towards decreased EBL in the combined group, this however did not reach statistical significance. Combined injection through the GPC and nasal cavity appears to be a safe method to decrease EBL during ESS.

High-resolution computed tomography analysis of the frontal sinus ostium: a pilot study.

PURPOSE: Identification and exposure of the frontal sinus recess (FSR) during endoscopic sinus surgery (ESS) are challenging due to the variable anatomy, the narrow opening of the frontal sinus ostium (FSO), and the proximity of vital anatomic structures. Hence, a strong understanding of frontal sinus anatomy is required to prevent intracranial entry. Consistent and easily identifiable landmarks and measurements could assist safe entry into the FSO. In this study, we determine the distances from the columella and anterior nasal spine (ANS) to the nasofrontal beak (NFB) and anterior skull base (ASB) using high-resolution computed tomography (HRCT) scans. METHODS: A radiographic analysis was performed at a tertiary care medical center. Measurements from the ANS to the NFB and ASB, and from the columella to the NFB and ASB were made using sagittal HRCT. Thirty-two HRCT scans were analyzed by three observers, and the mean distances and standard deviations were calculated. RESULTS: The mean distance from the ANS to the NFB was 52.3±3.4mm in men and 47.7±3.5mm in women (p<0.0001). Mean distance from the ANS to the ASB was 61.8±4.1mm in men and 56.5±4.1mm in women (p<0.0001). Mean distance from the columella to the NFB was 58.9±2.3mm in men and 53.0±3.3mm in women (p<0.0001), and from the columella to the ASB was 67.9±3.7 mm in men and 61.3±4.1mm in women (p<0.0001). CONCLUSION: While performing FSR exposure in ESS, it is recommended to stay a distance of less than 66.9 mm in men and 60.6mm in women from the columella to minimize intracranial complications.

Patient income level and health insurance correlate with differences in health care utilization during the COVID-19 pandemic.

Background: With the coronavirus outbreak of 2019 (COVID-19) came many changes in how health care is accessed and delivered. Perhaps most notable is the massive expansion of telemedicine, especially in the developed world. With pandemic-induced economic and health care system disruptions, it is reasonable to expect changes in how health care services are utilized by different patients. We examined how health care service usage trends changed for various patient demographics from the pre-COVID-19 era to the COVID-19 era. Design and methods: De-identified patient demographics and telemedicine, in-patient, in-person out-patient, radiology/procedures, and emergency department visit data (N = 1,164,719) between January 1st, 2019 and May 31st, 2021 were obtained from UHealth in Miami, Florida, USA. This cross-sectional study employed descriptive statistics and other tools to determine relationships between patient demographics and health system usage. Results: There were significant changes in health care usage and demographics for UHealth services from the pre-COVID-19 era to the COVID-19 era. There was an increase in telehealth visits and a corollary decrease of in-person out-patient visits (p < 0.001) along with increased health care utilization by those with commercial insurance (p < 0.001) during COVID-19. Lower-income patients had increased use of in-person out-patient services (p < 0.001). Non-Hispanic, English-speaking patients and those with higher median incomes had higher telemedicine usage. Conclusions: COVID-19 revealed differences in health care access, particularly telemedicine access, and highlighted differences in vulnerability among patient demographics. These trends are likely multifactorial and reflect changes in patients' preferences and disparities in care access.

Differentiation stage-specific expression of microRNAs in B lymphocytes and diffuse large B-cell lymphomas.

miRNAs are small RNA molecules binding to partially complementary sites in the 3'-UTR of target transcripts and repressing their expression. miRNAs orchestrate multiple cellular functions and play critical roles in cell differentiation and cancer development. We analyzed miRNA profiles in B-cell subsets during peripheral B-cell differentiation as well as in diffuse large B-cell lymphoma (DLBCL) cells. Our results show temporal changes in the miRNA expression during B-cell differentiation with a highly unique miRNA profile in germinal center (GC) lymphocytes. We provide experimental evidence that these changes may be physiologically relevant by demonstrating that GC-enriched hsa-miR-125b down-regulates the expression of IRF4 and PRDM1/BLIMP1, and memory B cell-enriched hsa-miR-223 down-regulates the expression of LMO2. We further demonstrate that although an important component of the biology of a malignant cell is inherited from its nontransformed cellular progenitor-GC centroblasts-aberrant miRNA expression is acquired upon cell transformation. A 9-miRNA signature was identified that could precisely differentiate the 2 major subtypes of DLBCL. Finally, expression of some of the miRNAs in this signature is correlated with clinical outcome of uniformly treated DLBCL patients.

Factors to Effective Telemedicine Visits During the COVID-19 Pandemic: Cohort Study.

BACKGROUND: With COVID-19 there was a rapid and abrupt rise in telemedicine implementation often without sufficient time for providers or patients to adapt. As telemedicine visits are likely to continue to play an important role in health care, it is crucial to strive for a better understanding of how to ensure completed telemedicine visits in our health system. Awareness of these barriers to effective telemedicine visits is necessary for a proactive approach to addressing issues. OBJECTIVE: The objective of this study was to identify variables that may affect telemedicine visit completion in order to determine actions that can be enacted across the entire health system to benefit all patients. METHODS: Data were collected from scheduled telemedicine visits (n=362,764) at the University of Miami Health System (UHealth) between March 1, 2020 and October 31, 2020. Descriptive statistics, mixed effects logistic regression, and random forest modeling were used to identify the most important patient-agnostic predictors of telemedicine completion. RESULTS: Using descriptive statistics, struggling telemedicine specialties, providers, and clinic locations were identified. Through mixed effects logistic regression (adjusting for clustering at the clinic site level), the most important predictors of completion included previsit phone call/SMS text message reminder status (confirmed vs not answered) (odds ratio [OR] 6.599, 95% CI 6.483-6.717), MyUHealthChart patient portal status (not activated vs activated) (OR 0.315, 95% CI 0.305-0.325), provider's specialty (primary care vs medical specialty) (OR 1.514, 95% CI 1.472-1.558), new to the UHealth system (yes vs no) (OR 1.285, 95% CI 1.201-1.374), and new to provider (yes vs no) (OR 0.875, 95% CI 0.859-0.891). Random forest modeling results mirrored those from logistic regression. CONCLUSIONS: The highest association with a completed telemedicine visit was the previsit appointment confirmation by the patient via phone call/SMS text message. An active patient portal account was the second strongest variable associated with completion, which underscored the importance of patients having set up their portal account before the telemedicine visit. Provider's specialty was the third strongest patient-agnostic characteristic associated with telemedicine completion rate. Telemedicine will likely continue to have an integral role in health care, and these results should be used as an important guide to improvement efforts. As a first step toward increasing completion rates, health care systems should focus on improvement of patient portal usage and use of previsit reminders. Optimization and intervention are necessary for those that are struggling with implementing telemedicine. We advise setting up a standardized workflow for staff.

Demographics associated with US healthcare disparities are exacerbated by the telemedicine surge during the COVID-19 pandemic.

INTRODUCTION: As coronavirus disease 2019 (COVID-19) hit the US, there was widespread and urgent implementation of telemedicine programs nationwide without much focus on the impact on patient populations with known existing healthcare disparities. To better understand which populations cannot access telemedicine during the coronavirus disease 2019 pandemic, this study aims to demographically describe and identify the most important demographic predictors of telemedicine visit completion in an urban health system. METHODS: Patient de-identified demographics and telemedicine visit data (N = 362,764) between March 1, 2020 and October 31, 2020 were combined with Internal Revenue Service 2018 individual income tax data by postal code. Descriptive statistics and mixed effects logistic regression were used to determine impactful patient predictors of telemedicine completion, while adjusting for clustering at the clinical site level. RESULTS: Many patient-specific demographics were found to be significant. Descriptive statistics showed older patients had lower rates of completion (p < 0.001). Also, Hispanic patients had statistically significant lower rates (p < 0.001). Overall, minorities (racial, ethnic, and language) had decreased odds ratios of successful telemedicine completion compared to the reference. DISCUSSION: While telemedicine use continues to be critical during the coronavirus disease 2019 pandemic, entire populations struggle with access-possibly widening existing disparities. These results contribute large datasets with significant findings to the limited research on telemedicine access and can help guide us in improving telemedicine disparities across our health systems and on a wider scale.

Airway implications of congenital sternal agenesis.

Congenital agenesis of the sternum is an extremely unusual malformation rarely encountered by the practicing Otolaryngologist. It typically arises in conjunction with other midline ventral congenital anomalies, including abdominal, diaphragmatic, and cardiac malformations. We report a case series of two patients managed with tracheotomy placement due to prolonged intubation. The first patient was a 63-day-old infant born at 34 weeks gestation with dysmorphic features, cleft lip and palate, and skeletal dysplasia, including absence of the sternum. The second patient was a 31-day-old infant born with ectopic cordis and diaphragmatic hernia. The inadequate closure of the anterior chest wall secondary to manubrium malformation or a variant contributes significantly to a child's inability to generate adequate ventilatory pressures. As a result, airway management must be considered not only to ensure airway patency but also an appropriate physiological environment to allow for adequate air exchange in the lungs.

Glutathione ester protects against hydroxynonenal-induced loss of auditory hair cells.

OBJECTIVE: Test the ability of glutathione monoethyl ester (GSH(e)) to protect auditory hair cells against the ototoxic effects of 4-hydroxy-2,3-nonenal (HNE). STUDY DESIGN AND SETTING: Organ of Corti explants were either untreated or treated with one of a series of four concentrations of GSH(e) for one day, then exposed to HNE. Counts of FITC-phalloidin-labeled hair cells determined both HNE ototoxicity and GSH(e) otoprotection. RESULTS: HNE was toxic to hair cells at physiologically relevant levels, eg, 400 muM, and GSH(e) provided a significant level of protection against HNE ototoxicity (P < 0.05) at all levels tested, ie, 1.16 to 9.3 mM. CONCLUSION: GSH(e) protects auditory hair cells from damage and loss initiated by a naturally occurring ototoxic molecule, ie, HNE (a by-product of oxidative stress). SIGNIFICANCE: Treatment with GSH(e) may be an effective therapy to protect the cochlea against the adverse effects of traumas (eg, electrode insertion) that generate oxidative stress.

Coblation assisted endoscopic juvenile nasopharyngeal angiofibroma resection.

To provide additional support for the use of coblation in the surgical treatment of juvenile nasopharyngeal angiofibroma (JNA) tumors. Coblation radiofrequency has been recently described in endoscopic sinus surgery for polyp and tumor resection from the sinuses to the skull base. This is a case series from our institution in which we safely and successfully treated three adolescent boys with JNA using the coblation assisted technique. The first case was the smallest of the cases (Radkowski stage IB) and was embolized pre-operatively. The second and third cases, both larger in size (Radkowski stage IIC and IIB) did not undergo pre-operative embolization. The total surgical times were 105, 160, and 150 min and the estimated blood losses were 150, 400, and 130 mL, respectively. This yielded a blood loss per minute rate of only 1.4, 2.5, and 0.9 mL/min for the respective cases. None of the three patients required post-operative blood transfusion, nasal packing, or hospitalization of greater than one day. Follow-up showed no complications and no recurrence in these patients. Coblation assisted transnasal endoscopic resection of JNA is a feasible technique that can dissect through and debulk JNA tumor, despite its extreme vascularity. The surgery can be performed with minimal morbidity and low intraoperative blood loss, even with non-embolized tumors up to Radkowski IIC. These finding further support complete resection of JNA tumors using minimally invasive coblation assisted techniques.

Endoscopic management of sinonasal hemangiopericytoma.

OBJECTIVE: Sinonasal hemangiopericytomas (SNHPCs) are rare perivascular tumors with low-grade malignant potential. Traditionally, these tumors have been treated with open approaches such as lateral rhinotomy, Caldwell-Luc, or transfacial approaches. Increased experience with endoscopic management of benign and malignant sinonasal tumors has led to a shift in management of SNHPC. The authors present their experience in the largest series of patients with SNHPC managed endoscopically. STUDY DESIGN AND SETTING: Case series at a tertiary care medical center. SUBJECTS AND METHOD: A retrospective chart review of all patients undergoing endoscopic management of SNHPC at the University of Miami between 1999 and 2008 was conducted. All endoscopic resections were performed with curative intent. RESULTS: Twelve patients with the diagnosis of SNHPC were treated endoscopically. Mean age was 62.5 years (range, 51-83 years). There were 6 men and 6 women. The mean follow-up was 41 months (range, 15-91 months). Seven (58.3%) presented with nasal obstruction, whereas 4 (41.6%) had epistaxis as their initial presenting symptom. Preoperative angiography or embolization was not performed in any case. Mean estimated blood loss was 630 mL (range, 100-1500 mL). Six patients underwent endonasal endoscopic anterior skull base resection; 4 had complete endoscopic resection all with negative margins. None underwent postoperative adjuvant treatment. No recurrence or metastatic disease was observed in this patient population. CONCLUSION: Endoscopic management of SNHPC is a feasible approach and did not compromise outcomes in this experience. In this series, familiarity with advance endoscopic sinus surgery was necessary to manage these patients. Postoperative adjuvant therapy was not necessary in this cohort.

Effect of coblation polypectomy on estimated blood loss in endoscopic sinus surgery.

BACKGROUND: We conducted a pilot study comparing estimated blood loss (EBL) using coblation-assisted endoscopic sinus surgery (CAESS) where coblation is used to debulk nasal polyps before microdebridement with a traditional microdebrider technique in chronic rhinosinusitis (CRS) patients with sinonasal polyps undergoing endoscopic sinus surgery (ESS). METHODS: A retrospective analysis was performed at a tertiary care center on patients with nasal polyposis undergoing ESS between January 2008 and July 2008. The University of Miami CT staging system was used preoperatively to evaluate the extent of sinonasal disease. The duration of surgery, blood loss per minute, total EBL, and demographic data were collected. RESULTS: Twenty-one patients underwent nasal polypectomy/ESS using CAESS and 16 patients underwent nasal polypectomy/ESS using microdebridement. The two groups had comparable University of Miami CT staging scores (p>0.05). The average EBL was 307.1+/-169.8 mL using coblation compared with 627.8+/-424.2 mL using microdebridement (p<0.05). The average duration of surgery using coblation was 116.2+/-41.7 minutes, compared with 125.3+/-48.4 minutes using microdebridement (p>0.05). The average blood loss per minute was 2.8+/-1.7 mL in the coblation group compared with 4.8+/-2.1 mL in the microdebridement group (p<0.05). Subgroup analyses showed a significant decrease in average EBL and EBL/minute to be only significant for revision cases (p<0.05) and not for primary cases (p>0.05). CONCLUSION: Coblation-assisted nasal polypectomy/ESS is associated with a statistically significant lower EBL and blood loss per minute when compared with traditional microdebridement technique. Coblation represents a new device that can reduce blood loss in patients with nasal polyposis undergoing traditional revision ESS. Further prospective randomized trials are needed to validate these findings.
