ABSTRACT Purpose To verify the self-perception of symptoms and vocal fatigue related to thyroidectomy in individuals with thyroid cancer in the pre, immediate post and late post-operative moments, and to analyze the influence of gender. Methods Intervention study before and after with 20 individuals, mean age 46 years, evaluated before surgery (M1), immediately after surgery (M2) and in the late postoperative period (M3) of thyroidectomy. Individuals answered the instruments: Voice Symptoms Scale, Vocal Fatigue Index and Thyroidectomy-Related Voice and Symptom Questionnaire. Data were analyzed descriptively and inferentially. Results In self-assessment of vocal symptoms of the total domains and limitation, M1 (p<0.001; p<0.001, respectively) and M3 (p=0.013; p=0.001, respectively) had significantly lower values than the M2. For the physical domain of self-assessment of vocal symptoms, the M3 showed statistically lower values than the M1 (p=0.006) and the M2 (p<0.001) assessments. Depending on the moment, the oropharyngolaryngeal symptoms in M3 had significantly lower values ​​than M2 (p=0.004) and M1 (p=0.028). Male scores were significantly lower than female scores in the self-assessment of fatigue symptoms in the fatigue and vocal limitation domain (p=0.035), regardless of the time of assessment. Conclusion Physical vocal symptoms and thyroidectomy-related symptoms decrease in the late postoperative period; total vocal symptoms and limitation increasing in the immediate postoperative period and decrease in the late postoperative period. Women have a higher perception of vocal fatigue and limitation, and of total and vocal symptoms related to thyroidectomy.

Multiparameter Voice Assessment in Dysphonics: Correlation Between Objective and Perceptual Parameters.

BACKGROUND: Perceptual assessment and objective measures of voice provide a quantifiable tool for determining the degree of glottal closure, thus helping to distinguish dysphonic voices from normal voices. The correlation between the perceptual and objective parameters of voice in dysphonic can enable the voice pathologist to be more effective in differentiating the normal voices from dysphonic voices. However, only a few studies have investigated the correlation between these measures. OBJECTIVE: To document the differences in the perceptual and objective parameters of voice in participants with dysphonia and normal controls and to investigate the correlation between the perceptual and objective parameters of voice among participants with dysphonia. STUDY DESIGN: This investigation deployed standard group comparison and a retrospective study. METHODS: Two groups of participants were included in the study. Participants in group 1 were diagnosed as having a voice disorder secondary to organic pathologies and group 2 participants had a clinically normal voice. Phonation samples of all the participants were collected and perceptual analysis was carried out using the GRBAS rating scale. As part of the objective measures, acoustic and cepstral measures were extracted from the phonation samples. RESULTS: The analysis of the results revealed significant differences in perceptual ratings between the normal (control) and dysphonic groups. The mean values of all the objective measures of voice presented significant differences between participants of both groups. The perceptual ratings of grade, breathiness, and roughness showed better correlations with the cepstral measures than with the time-based acoustic measures. CONCLUSIONS: Further foraging research on the correlation between perceptual and objective measures of voice in various degrees of dysphonia will improve reliability while discriminating and quantifying hoarse, harsh and breathy voices from modal voices.

The cepstral spectral index of dysphonia, the acoustic voice quality index and the acoustic breathiness index as novel multiparametric indices for acoustic assessment of voice quality.

PURPOSE OF REVIEW: The objective assessment of voice quality using acoustic measures is an important pillar of voice diagnostics. This article reviews three recent acoustic measures and their clinical use in phoniatrics and laryngology. RECENT FINDINGS: Two acoustic parameters, the cepstral spectral index of dysphonia (CSID) and the acoustic voice quality index (AVQI), have gained importance as validated multiparametric indices in the objective assessment of hoarseness because they include both continuous speech and sustained vowels. The acoustic breathiness index (ABI), another multiparametric index, assesses breathiness admixture during phonation and identifies it robustly, unaffected by other characteristics of dysphonia such as roughness. SUMMARY: Acoustic measurements are useful diagnostic tools when used correctly with an appropriate recording system, consideration of environment and use of software programs. CSID, AVQI and ABI objectively improve the detection of voice quality abnormalities. In addition to their proven validity, their application is simple and their usability for clinicians is high.

Self-Assessment of Vocal Fatigue in Muscle Tension Dysphonia and Vocal Nodules: A Preliminary Analysis of the Discriminatory Potential of the Croatian Adaptation of the Vocal Fatigue Index (VFI-C).

In this paper the authors hypothesize that the intensity of subjective experience of vocal fatigue (VF) potentially reflects primary (hyper) functional vocal disorders (primary muscle tension dysphonia - MTD) differently than structural vocal disorders of functional etiology (MTD type 2a). Given the reported benefit of self-evaluation in the quantification of VF, the goal of this study was to test the potential of the Croatian adaptation of the Vocal Fatigue Index questionnaire (VFI-C) in order to show different VF intensities for the two above-mentioned diagnoses of vocal disorders. In total, 69 vocal nonprofessionals of both sexes (average age 41.5 years, ±13.8 years), with phoniatrically determined vocal disorders of varying etiology and 50 vocal nonprofessionals of both sexes without vocal disorders (average age 44 years, ±14.7 years), recruited at otorhinolaryngological clinics at medical centers in Zagreb and Split, completed the VFI-C. Psychometric characteristics of the VFI-C were determined by calculating Cronbach's alpha and the intraclass correlation coefficient , and by employing factor analysis, and the nonparametrical Mann-Whitney U test. Considering the favorable psychometric data, a descriptive analysis of the VF self-evaluation results was done for groups of participants with MTD diagnoses (10 people with an average age of 33.4, ±5.9 years) and vocal nodules ( 21 people with an average age of 37.3, ±12.8 years). A comparison was made of the average results of the MTD and vocal nodules groups using the nonparametric Mann-Whitney U test. Given that perceived VF was found to be greater in the MTD group, it appears that the self-evaluation of VF has a discriminatory potential for different vocal difficulties, which justifies the further verification of the complementary usefulness of VF gradation in clinical descriptions of different vocal disorders.

Usage of airway ultrasound as an assessment and prediction tool of a difficult airway management.

Airway assessment is important in emergency airway management. A difficult airway can lead to life-threatening complications. A perfect airway assessment tool does not exist and unanticipated difficulty will remain unforeseen. Current bedside clinical predictors of the difficult airway are unreliable but airway ultrasound can be used as an adjunct to predict difficult laryngoscopy. We report a case of a 60-year-old man presenting to the emergency department with shortness of breath, hoarseness of voice and stridor. Airway ultrasound revealed a large laryngeal mass narrowing the upper airway, extending to bilateral vocal cords with heterogenous echogenicity. In view of impending complete upper airway obstruction, acute respiratory distress and airway ultrasound findings, urgent emergency tracheostomy was chosen as definitive airway over endotracheal intubation or surgical cricothyroidotomy. Point of care ultrasound (POCUS) was used to evaluate this patient with severe upper airway obstruction. A laryngeal mass was detected by ultrasound and this pointed towards the presence of a difficult airway. POCUS was a good non-invasive tool used for airway assessment in this uncooperative and unstable patient. Ultrasound predictors of the difficult airway include the inability to visualize the hyoid bone, short hyomental distance ratio, high pretracheal anterior neck thickness and large tongue size. Besides airway assessment, ultrasound can also help to predict endotracheal tube size, confirm intubation and guide emergency airway procedures such as cricothyroidotomy and tracheostomy. Point of care ultrasound of the upper airway can be used in airway assessment to identify distorted airway anatomy, pathological lesions and guide treatment decisions.

Pansori today: aesthetic demands vs. vocal health / Pansori hoy: demandas estéticas vs. salud vocal

Introduction:Pansori is a traditional Korean dramatic art form, which likely ap-peared in the mid-eighteenth century in the southern region of Korea. In pansorithere is a strong inclination toward preserving tradition, especially in regard to train-ing, which is generally considered particularly demanding in terms of risks to vo-cal health. Nevertheless ­as highlighted by recent studies­ some innovations took place in pansori characteristics and performances in the last few decades.Objective: We hypothesize that these innovations have impacted the attitudes of singers and teachers towards pansori training and vocal health issues, and that a new approach to voice training in pansori might be recommended.Method: Starting with recent evolutions of pansori and considering previous studies, we discuss how these changes might produce innovations ­or at least a demand for innovation­ in pansori's training. We also try to capture the viewpoint of pansori stu-dents and performers, through an anonymous survey.Results: Although further investigation is required, the results suggest that a new approach in teaching pansori is emerging and it is increasingly requested by the train-ee performers, despite some criticisms from traditionalists.Conclusion: Unlike previously thought, perhaps a more scientific and health-con-scious approach to pansori voice training will be something from which many pansorisingers can benefit.

Introducción: Pansori es una forma de arte dramático tradicional coreano que pro-bablemente apareció a mediados del siglo XVIII en la región sur de Corea. En pansorihay una fuerte inclinación a preservar la tradición, especialmente en lo que respecta al entrenamiento, que generalmente se considera particularmente exigente en térmi-nos de riesgos para la salud vocal. Sin embargo, como destacan estudios recientes, se produjeron algunas innovaciones en las características y actuaciones del pansori en las últimas décadas.Objetivo: Hipotetizamos que estas innovaciones han impactado las actitudes de can-tantes y profesores hacia la formación del pansori y los problemas de salud vocal, y que podría recomendarse un nuevo enfoque para el entrenamiento de la voz en pansori.Método: Comenzando con las evoluciones recientes de pansori y considerando es-tudios previos, discutimos cómo estos cambios pueden producir innovaciones, o al menos una demanda de innovación, en la formación de pansori. También tratamos de captar el punto de vista de los estudiantes e intérpretes de pansori, a través de una encuesta anónima.Resultados: Aunque se requiere más investigación, los resultados sugieren que está surgiendo un nuevo enfoque en la enseñanza del pansori y es cada vez más solicitado por los artistas en formación, a pesar de algunas críticas de los tradicionalistas.Conclusión: A diferencia de lo que se pensaba anteriormente, quizás un enfoque más científico y consciente de la salud para el entrenamiento de la voz en pansori será algo de lo que muchos cantantes de pansori puedan beneficiarse

Assessment and Diagnostic Accuracy Evaluation of the Reflux Symptom Index (RSI) Scale: Psychometric Properties using Optimal Scaling Techniques.

OBJECTIVES: To investigate the psychometric properties of the reflux symptom index (RSI) as short screening approach for the diagnostic of laryngopharyngeal reflux (LPR) in patients with confirmed diagnosed regarding the 24-hour multichannel intraluminal impedance-pH monitoring (MII-pH). METHODS: From January 2017 to December 2018, 56 patients with LPR symptoms and 71 healthy individuals (control group) were prospectively enrolled. The LPR diagnosis was confirmed through MII-pH results. All subjects (n = 127) fulfilled RSI and the Reflux Finding Score (RFS) was performed through flexible fiberoptic endoscopy. The sensitivity and the specificity of RSI was assessed by ROC (Receiver Operating Characteristic) analysis. RESULTS: A total of 15 LPR patients (26.8%) of the clinical group met MII-pH diagnostic criteria. Among subjects classified as positive for MII- pH diagnoses, RSI and RFS mean scores were respectively 20 (SD ± 10.5) and 7.1 (SD ± 2.5), values not significantly different compared to the negative MII-pH group. The metric analysis of the items led to the realization of a binary recoding of the score. Both versions had similar psychometric properties, α was 0.840 for RSI original version and 0.836 for RSI binary version. High and comparable area under curve (AUC) values indicate a good ability of both scales to discriminate between individuals with and without LPR pathology diagnosis. Based on balanced sensitivity and specificity, the optimal cut-off scores for LPR pathology were ≥ 5 for RSI binary version and ≥ 15 for RSI original version. Both version overestimated LPR prevalence. The original version had more sensitivity and the RSI Binary version had more specificity. CONCLUSIONS: It would be necessary to think about modifying the original RSI in order to improve its sensitivity and specificity (RSI binary version, adding or changing some items), or to introduce new scores in order to better frame the probably affected of LPR patient.

Is Vocal Cord Assessment before Total Thyroidectomy Required for All Patients?

We investigated whether laryngoscopy should be performed before total thyroidectomy on all patients without a history of neck surgery. A total of 2523 patients who underwent total thyroidectomy between January 1, 2013, and March 18, 2018, were retrospectively examined. Preoperative vocal cord examination was performed on 2070 of these patients by the otorhinolaryngology department using indirect laryngoscopy. Patients with a history of neck or thyroid surgery were not included in the study. The patients were evaluated in terms of age, gender, symptom (hoarseness/dyspnea), comorbidity, surgical history, biopsy, nodule diameter, pathological diagnosis, and tracheal deviation. Preoperative vocal cord paralysis was detected in 0.8 per cent of the patients (17/2070). Four patients (23.5%) were male and 13 patients (76.5%) were female. The mean age was 62 (range, 25-82) years. Seven of the 17 patients (41%) were symptomatic, with complaints of dyspnea in five and hoarseness in two. The univariate analysis revealed that a nodule diameter >30 mm and the presence of dyspnea were associated with vocal cord damage. Furthermore, the multivariate analysis showed that dyspnea alone was an independent variable (P = 0.011). It is recommended that preoperative vocal cord evaluation should be performed only in patients with severe symptoms, such as dyspnea.

Head and Neck Surgical Oncology Choosing Wisely Campaign: imaging for patients with hoarseness, fine needle aspiration for neck mass, and ultrasound for odynophagia.

Choosing Wisely Canada, is a campaign designed to raise awareness regarding inappropriate or unnecessary tests and treatments. The Canadian Society of Otolaryngology - Head & Neck Surgery and the Canadian Association of Head and Neck Surgical Oncologists developed a Choosing Wisely Canada list to help promote high quality care for patients presenting with disorders of the head and neck: (1) Don't order imaging - computer tomography (CT) or magnetic resonance imaging (MRI) - as the initial investigation for patients presenting with a chief complaint of hoarseness, (2) Don't perform an open biopsy or excision of a neck mass without having first considered a fine needle aspiration (FNA) biopsy and, (3) Don't order neck ultrasound to investigate odynophagia (discomfort or pain with swallowing) or globus sensation.

Subjective and objective assessment of voice quality in pregnancy.

During pregnancy, voice quality disorders may occur in form of: edema, dryness, nervousness. The aim of the study is subjective and objective evaluation of voice quality in pregnant women. The study included 20 women in the third trimester of pregnancy, age of 20-31 diagnosed at the Department of Clinical Phonoaudiology and Logopedics, Medical University of Bialystok. Subjective assessment has been based on the GRBAS scale. Objective assessment of the vocal organ used the HSDI technique (High Speed Digital Imaging). In the laryngeal visualization, high-speed camera (HS) using rigid endoscope with 90 ° optics has been used. Vibration of vocal folds has been recorded during phonation of vowel "e" at 4000 frames / sec. The glottal closure (GTs), symmetry, regularity and synchronization of vocal folds vibration have been assessed. In estimating the degree of glottal insufficiency, kymography of the larynx has been performed by analyzing the value of Open Quotient (OQ). Objective acoustic evaluation of voice has been also conducted using DiagnoScope Specjalista Program. Hoarseness has been observed in 15 pregnant women, whereas voice fatigability in 20 patients. Using HSDI, the edema of vocal folds in part of the group has been observed. Decreased MPT has been found in all examined women in the third trimester of pregnancy. Hoarseness and fatigability of voice are the most frequent subjective symptoms of voice organ in the third trimester of pregnancy. Decreased MPT is recorded objectively, as well as edema and insufficiency of vocal folds using HSDI technique.

[A systematic evaluation of the assessment methods of spasmoidc dysphonia].

To review the available subjective and objective evaluation methods used in the assessment of the spasmodic dysphonia.A systematic literature search was conducted in PubMed,web of science,EBSCO and Ovid database,date limited from 2000 to 2015,language limited English,using the following key words: "spasmodic dysphonia" OR "spastic dysphonia" AND "evaluat*" OR " diagnosis" OR "treatment" OR "assess*".Screening the titles and abstracts,and reading the full text,studies met the inclusion criteria were enrolled.The references of eligible publications were manually searched to identify additional studies.A total of 967 literatures were retrieved.Finally,twenty-three papers were enrolled in the study according to the inclusion criteria.Evaluation methods were mainly divided into subjective and objective,including perception,subjective self-assessment;and aerodynamic,acoustic analysis,respectively.The assessment of spasmodic dysphonia should be multidimensional.

Characteristics of a Dysphonic Population Referred for Voice Assessment and/or Voice Therapy.

OBJECTIVE: The aim of this study was to define patient characteristics of a dysphonic population in terms of voice disorder, gender, age, and subjective and objective vocal parameters and to explore the relevant characteristics of the most frequent groups of voice disorders. PATIENTS AND METHODS: Patient records from 4,447 subjects referred for voice assessment and/or voice therapy were analyzed. RESULTS: Significantly more cases of dysphonia were structural as compared to nonstructural. This significant difference was found in almost all age groups. Significantly more women were diagnosed with dysphonia than men. The most common symptom was light-to-moderate hoarseness. The average voice handicap index was 31 and the average dysphonia severity index was -0.6. Vocal fold nodules (VFN), functional voice disorders (FVD) and vocal fold paralysis (VFP) were the three most frequently diagnosed vocal pathologies and were analyzed in detail. Women were found to be significantly more vulnerable to FVD, VFN and cysts, whereas men were significantly more often diagnosed with carcinoma, hyperkeratosis, laryngitis, papillomatosis, presbyphonia, puberphonia and VFP. CONCLUSIONS: The results of this study allow a better estimation of the clinical needs and costs for a specific dysphonic population looking for help and highlight the gender-related risks of specific voice disorders.

Disfonia: avaliação e manejo inicial / Dysphonia: assessment and initial management

Alterações na voz podem ser tanto causadas por doenças benignas ou autolimitadas, quanto por patologias malignas. Essas alterações podem causar prejuízo na qualidade de vida do paciente. O objetivo deste capítulo é ajudar o clínico a diagnosticar e manejar inicialmente as alterações na voz de seus pacientes.

Voice disorders can be caused by benign, self-limited diseases or even by malignances. These disorders can reduce the patient's quality of life. The aim of this chapter is to help the clinician to diagnose and to provide the early management of the patients' voice disorders.

The upper respiratory pyramid: early factors and later treatment utilization in World Trade Center exposed firefighters.

BACKGROUND: We investigated early post 9/11 factors that could predict rhinosinusitis healthcare utilization costs up to 11 years later in 8,079 World Trade Center-exposed rescue/recovery workers. METHODS: We used bivariate and multivariate analytic techniques to investigate utilization outcomes; we also used a pyramid framework to describe rhinosinusitis healthcare groups at early (by 9/11/2005) and late (by 9/11/2012) time points. RESULTS: Multivariate models showed that pre-9/11/2005 chronic rhinosinusitis diagnoses and nasal symptoms predicted final year healthcare utilization outcomes more than a decade after WTC exposure. The relative proportion of workers on each pyramid level changed significantly during the study period. CONCLUSIONS: Diagnoses of chronic rhinosinusitis within 4 years of a major inhalation event only partially explain future healthcare utilization. Exposure intensity, early symptoms and other factors must also be considered when anticipating future healthcare needs.

[Pathophysiology, assessment and treatment of laryngopharyngeal reflux]. / Physiopathologie, évaluation et traitement du reflux laryngopharyngé.

Laryngopharyngeal reflux is a prevalent, yet incompletely understood, ENT disorder accounting for 8 to 10% of patients consulting ENT. This clinical entity, increasingly considered as different from gastroesophageal reflux disease, may greatly affect the quality of life of patients through vocal and digestive symptoms. Debate persists concerning pathophysiology, diagnosis, and treatment. The aim of this review is to study the current literature about the pathophysiology, diagnosis, treatment, and the outcomes in the follow-up.

High economic burden of caring for patients with suspected extraesophageal reflux.

OBJECTIVES: Extraesophageal symptoms are common manifestations of gastroesophageal reflux disease (GERD). Lack of a definitive diagnostic or treatment standards complicate management, which often leads to multiple specialty consultations, procedures, pharmaceuticals and diagnostic tests. The aim of this study was to determine the economic burden associated with extraesophageal reflux (EER). METHODS: Direct costs of evaluation were estimated for patients referred with symptoms attributed to EER between 2007 and 2011. Medicare payment for evaluation and management and pharmaceutical prices was used to calculate first year and overall costs of evaluating and treating extraesophageal symptoms attributed to reflux. RESULTS: Overall, 281 patients were studied (cough (50%), hoarseness (23%), globus/post-nasal drainage (15%), asthma (9%), and sore throat (3%)). Over a median (interquartile range) of 32 (16-46) months follow-up, patients had a mean (95% confidence interval) of 10.1 (9.4-10.9) consultations with specialists and underwent 6.4 (3-9) diagnostic procedures. Overall, the mean initial year direct cost was $5,438 per patient being evaluated for EER. Medical and non-medical components contributed $5,154 and $283. Of the overall cost, 52% were attributable to the use of proton pump inhibitors. During the initial year, direct costs were 5.6 times higher than those reported for typical GERD ($971). A total of 54% of patients reported improvement of symptoms. Overall cost per improved patient was $13,700. CONCLUSIONS: EER contributes substantially to health-care expenditures. In this cohort, the cost for initial year's evaluation and treatment of EER symptoms was quintuple that of typical GERD. Prescription costs and, in particular, proton pump inhibitors were the single greatest contributor to the cost of EER management.

Reliability and validity of the Italian version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V).

OBJECTIVES: To evaluate the reliability and validity of the Italian version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V). PATIENTS AND METHODS: Eighty dysphonic patients and 120 asymptomatic subjects were enrolled. The voice signal of each participant was recorded, listened to and rated by 3 licensed speech-language pathologists using the GRBAS scale and the Italian version of the CAPE-V. The intra- and interrater reliability of the CAPE-V was assessed as well as the degree of association between the CAPE-V and GRBAS judgments. The CAPE-V values were also compared between the patients with dysphonia and the asymptomatic subjects. RESULTS: The intra- and interrater reliability appeared to be good for all the parameters except for the strain parameter. The attributes 'consistent' and 'intermittent' demonstrated optimal intra- and interrater reliability. The difference between pathological and control groups was significant for six perceptual parameters. The highest average correlation between GRBAS and CAPE-V judgments was found between overall severity and grade while the lowest was found between the two strain scales. CAPE-V profiles differed significantly between different pathological groups. CONCLUSION: The Italian version of CAPE-V appears to be a reliable and valid tool for the perceptual analysis of the voice signal.

Comparative assessment of the voice in patients treated for early glottis cancer by laser cordectomy or radiotherapy.

INTRODUCTION: Adaptation of laser surgery in laryngeal cancer treatment in 1970s led to great successes and common acceptation of this treatment method in cancer treatment. The results of cancer treatment with CO(2) laser are the same as after radiotherapy or external access method. MATERIAL AND METHODS: The study included 63 patients treated for glottis cancer T1. 33 persons were treated by cordectomy type III with transmuscular cordectomy using CO(2) laser. The remaining 30 persons are patients treated using radiotherapy with so called "small spots". The tested material consisted of 100% squamosus carcinoma. The patients qualified for the examination received a card of voice self-examination. The perceptive examination of the voice was performed according to the GRBAS scale where each of parameters is defined in a four degree scale of the particular disturbance degree. The mobility and vibrations of the vocal folds were accessed using videolaryngoscopy while the acoustic analysis was performed on the basis of the acoustic analysis module. RESULTS: On the basis of the patients' voice quality self-assessment and the perceptive assessment of the voice quality based on the GRBAS scale, no significant differences between the groups were found. Furthermore no statistically significant differences were found for the phonation closure and maximal phonation time in both groups.

Variation of health-care resource utilization according to GERD-associated complications.

Complications associated with gastroesophageal reflux disease (GERD) can include esophageal stricture, Barrett's esophagus, gastrointestinal hemorrhage, and extraesophageal symptoms. The impact of GERD-associated complications on health-care utilization deserves further evaluation. We identified commercial enrollees 18-75 years old with claims for GERD (International Classification of Diseases, Ninth Revision, Clinical Modification Codes: 530.81 or 530.11) and subsequent usage of proton pump inhibitors from 01/01/05 to 06/30/09. The initial GERD diagnosis date was designated as the index date, and patients were studied for 6 months preindex and postindex. Eligible patients were subsequently stratified based on medical claims for GERD-associated complications as follows: stage A (GERD diagnosis, no other symptoms), stage B (GERD + extraesophageal symptoms), stage C (GERD + Barrett's esophagus), stage D (GERD + esophageal stricture), and stage E (GERD + iron-deficiency anemia or acute upper gastrointestinal hemorrhage). Patient characteristics, health-care utilization, and costs were compared between stage A and each stage with complicated GERD (B-D). Of the 174,597 patients who were eligible for analysis, 74% were classified as stage A, 20% stage B, 1% stage C, 2% stage D, and 3% stage E. Relative to stage A, patients in stages C, D, and E were significantly more likely to visit a gastroenterologist (13% vs. 68%, 71%, and 38%, respectively) and had higher rates of esophageal ulcers (0.3% vs. 8%, 5%, and 3%, respectively) and Nissen fundoplication (0.05% vs. 0.6%, 0.3%, and 0.2%, respectively). Six-month GERD-related costs ranged from $615/patient (stage A) to $1714/patient (stage D); all-cause costs ranged from $4195/patient (stage A) to $11,340/patient (stage E). Compared with stage A, all other cohorts had significantly higher all-cause and GERD-related costs (P < 0.0001 for all comparisons). While patients with more severe GERD represented a relatively small portion of the GERD cohort, they demonstrated significantly greater health-care costs and overall utilization than patients with uncomplicated GERD.
