Delphi Method Consensus on Priority Global Otolaryngology-Head and Neck Surgery Conditions and Procedures

John M. Global Authorship Representation in Otolaryngology Clinical Trials

Objective

To investigate global authorship representation in clinical trials published in major general otolaryngology journals over the past two decades.

Methods

We conducted a bibliometric analysis of clinical trials published in four major general otolaryngology journals between 2000 and 2020. The affiliated nationalities of authors in leading positions (first, senior, corresponding) were reviewed for each trial. Countries were classified by World Bank income group. The temporal trajectory of representation was estimated in multivariable logistic regression models, adjusting for publication environment and study design. The academic impact of trials across income groups was also compared.

Results

Among 1432 trials, the leading authors for most were affiliated with non-USA nations (57%) and high-income countries (HIC) (87%). Trials led by authors from upper-middle income countries (UMIC), lower-middle income countries (LMIC), and low-income countries (LIC) were severely underrepresented (11%, 3%, 0%, respectively). Over time, non-USA representation increased (+0.5%, 95% CI [+0.13%, +0.92%] per year), HIC representation decreased (-0.45% [-0.77%, -0.12%]), UMIC representation remained stable (0.19% [-0.13%, 0.51%]), LMIC representation mildly increased (0.26% [0.16%, 0.35%]), and LIC representation remained absent (0%). UMIC author-led trials (aIRR 0.80 [0.68, 0.94]) received significantly fewer citations compared to HIC author-led trials regardless of study design and publication year.

Conclusions

The clinical trial literature in the four most widely circulated OHNS journals is dominated by HIC authorship, with only marginal growth in LMIC contributions and no representation from LICs over the past two decades. This underrepresentation may impact the applicability of clinical guidelines in lower-income regions.

Development of the West China Tinnitus Impact Inventory and Analysis of Its Reliability and Validity

OBJECTIVES

Owing to differences in cultural background, education level, and lifestyle, certain items of existing tinnitus evaluation scales are difficult for Chinese patients to understand, despite being translated. However, few independently developed scales have been developed specifically for Chinese patients. Therefore, with this study, we aimed to construct a tinnitus scale, the West China Tinnitus Impact Inventory (WCTII), suitable for the accurate reflection of the impact and severity of the disease in this population.

DESIGN

Basic items were obtained through semistructured interviews with patients with tinnitus. We invited 23 domestic experts on tinnitus to form an expert group. The basic items were modified using the Delphi method. Cronbach's α values for the scale scores and correlation coefficients between the items and the scale scores were calculated. Items with correlation coefficients <0.5 were deleted. Exploratory factor analysis was conducted to determine the scale structure of the items remaining after item deletion. The intragroup correlation coefficient was used to assess the scale's test-retest reliability. The Pearson correlation coefficient between the scale scores and the scores for the Chinese-Mandarin version of the Tinnitus Handicap Inventory was used to evaluate concurrent validity.

RESULTS

After five rounds of expert correspondence and exploratory factor analysis, we determined the content and structure of the scale. The WCTII consists of 19 items in 4 subscales, namely, F1: the impact of tinnitus on emotion (items 1 to 9); F2: the impact of tinnitus on sleep (items 10 to 12); F3: patients' beliefs about their tinnitus (items 13 to 16, 19); and F4: the impact of tinnitus on auditory processing ability (items 17 to 18). The overall Cronbach's α was 0.934. The Cronbach's α values for F1 to F4 were 0.912, 0.843, 0.829, and 0.838, respectively. The intragroup correlation coefficient (95% confidence interval) of the total scale and F1 to F4 were 0.779 (0.549 to 0.886), 0.738 (0.496 to 0.860), 0.826 (0.713 to 0.897), 0.720 (0.536 to 0.836), and 0.715 (0.532 to 0.832), respectively. The correlation between the WCTII and Chinese-Mandarin version of the Tinnitus Handicap Inventory scores was 0.849 ( p < 0.001).

CONCLUSIONS

The WCTII yielded satisfactory reliability and validity, indicating that it can be used to assess the severity of tinnitus in Chinese patients.

Essential Equipment for Baseline Otolaryngology-Head and Neck Surgery Care: A Global Cross-Sectional Survey

Objective

Availability of surgical equipment and access to essential clinical services remains an important barrier to surgical care delivery, particularly in low- and middle-income countries (LMICs). This study aims to characterize the relative availability of essential equipment for otolaryngology-head and neck surgery (OHNS) care across World Bank income groups.

Methods

We conducted a cross-sectional survey on otolaryngologists' perceptions on the availability of surgical equipment and ancillary services in their respective practice settings per a 5-point Likert scale ranging from never to always available. The study was disseminated online via professional societies, personal contacts, and social media. Eligible participants included otolaryngologists from 194 WHO-recognized countries, which were grouped by World Bank income group classification and WHO region.

Results

The study involved 146 otolaryngologists, 69 (47%) from high-income countries (HICs), and 77 (53%) from LMICs. LMIC respondents were predominantly from the African and South-East Asian regions, which comprised 48% and 7.8% of all LMIC respondents, respectively. Results revealed significant differences in the availability of otologic, rhinologic, and endoscopic airway equipment between HICs and LMICs. Differences existed among commonly used equipment such as tympanomastoidectomy equipment and rigid bronchoscopy, to subspecialized equipment such as functional endoscopic sinus surgery equipment and cochlear implants (p < 0.05 each).

Conclusions

The study highlighted key disparities in the availability of essential equipment for baseline OHNS care, especially for pediatric airway and otologic conditions. These results can be used to guide investment and advocacy efforts to improve specialty-specific surgical infrastructure relative to the global burden of OHNS diseases in low-resource settings.

Examining the Obstacles to Timely Otolaryngology Care in Ethiopia and Zimbabwe: A Comparative Analysis

This study compares delays in otolaryngologic care between patients in Mekelle, Ethiopia and Harare, Zimbabwe using the Three Delays model. Patient surveys conducted among 46 patients in Zimbabwe during October 2022 and 105 patients in Ethiopia during June 2023 revealed a significantly higher prevalence of delays in seeking and reaching care in Ethiopia. This was in the aftermath of the Tigray War, which damaged the region's health care infrastructure and diminished the trust of patients. In Zimbabwe, there was poor awareness among patients and nonotolaryngologist providers of otolaryngology disease and care capacity leading to delays in seeking and reaching care. Patients in both countries faced delays in receiving appropriate care due to resource limitations, with Ethiopia's constraints worsened by the recent war and Zimbabwe's by consistent health care underfunding. The longest delays were observed in head and neck oncology care. These findings provide a foundation for understanding otolaryngologic care delays in these low- and middle-income countries.

International Expert Consensus on Defining Textbook Oncologic Outcomes in Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Colorectal Peritoneal Metastasis

BACKGROUND

Textbook oncologic outcome (TOO) is a composite metric shown to correlate with improved survival after curative intent oncologic procedures. Despite increasing use among disciplines in surgical oncology, no consensus exists for its definition in cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC).

STUDY DESIGN

An international consensus-based study employed a Delphi methodology to achieve agreement. Fifty-four senior surgeons from the peritoneal surface malignancies field received a questionnaire comprising TOO parameters divided into 3 surgical domains: operative, short-term, and long-term postoperative outcomes. Two online meetings with participants defined the new criteria. Consensus was achieved when 75% of agreement rate was reached. Clinical data of patients who underwent CRS and HIPEC for colorectal peritoneal metastasis between 2010 and 2022 from 1 designated center (Sheba Medical Center) were collected, the consensus definition applied and outcomes analyzed.

RESULTS

Thirty-eight surgeons (70%) participated. Expert consensus TOO parameters for colorectal peritoneal metastasis CRS and HIPEC included the absence of unplanned reoperations during 30 days postoperation, absence of severe postoperative complications (Clavien-Dindo ≥III), absence of unplanned readmissions during 30 days postoperation, 90-day postoperative mortality, and absence of contraindications for chemotherapy within 12 weeks from operation, and included the achievement of complete cytoreduction (CC0). The study cohort consisted of 251 patients, and 151 (60%) met TOO criteria. Patients who achieved TOO had significantly better overall survival (median 67.5 months, 95% CI) vs patients who did not achieve TOO (median 44.6 months, 95% CI, p < 0.001) and significantly improved disease-free survival (median, 12 months, 95% CI, vs 9 months, 95% CI, p = 0.01).

CONCLUSIONS

Achievement of TOO as defined by consensus statement is associated with improved survival.

Essential equipment and services for otolaryngology care: a proposal by the Global Otolaryngology-Head and Neck Surgery Initiative

PURPOSE OF REVIEW

To highlight the need for comprehensive resource lists to provide baseline care of otolaryngologic conditions; to present a proposed list of essential equipment and services that may be applied toward surgical systems research, policymaking, and charitable efforts in global otolaryngology-head and neck surgery.

RECENT FINDINGS

To provide effective and high-quality surgical care across care settings, there must be a global standard for equipment and ancillary services necessary to provide baseline care. Though there have been efforts to devise resource standards via equipment lists and appraisal tools, these have been limited in scope to general surgery, emergency care, and a few other subspecialty surgical contexts. Recent efforts have brought attention to the significant burden imposed by otolaryngologic conditions such as hearing loss, otitis media, head and neck cancer, head and neck trauma, and upper airway foreign bodies. Yet, there has not been a comprehensive list of resources necessary to provide baseline care for common otolaryngologic conditions.

SUMMARY

Through an internal survey of its members, the Global Otolaryngology-Head and Neck Surgery Initiative has compiled a list of essential equipment and services to provide baseline care of otolaryngologic conditions. Our efforts aimed to address common otolaryngologic conditions that have been previously identified as high-priority with respect to prevalence and burden of disease. This expert-driven list of essential resources functions as an initial framework to be adapted for internal quality assessment, implementation research, health policy development, and economic priority-setting.

Developing Consensus on Priority Pediatric Otolaryngology-Head and Neck Surgery Conditions and Procedures

OBJECTIVE

The aim of this study was to develop an international expert consensus on priority pediatric otolaryngology-head and neck surgery (OHNS) conditions and procedures for which all national health systems globally should be capable of managing.

STUDY DESIGN

The Delphi method is a multiround online questionnaire and was administered internationally to otolaryngologists with a focus on pediatric populations. This study was administered in parallel to a Delphi survey focusing on adult OHNS conditions amongst adult otolaryngology experts.

SETTING

International online survey.

METHODS

In round 1, participants listed the top 15 pediatric otolaryngological conditions and top 15 pediatric otolaryngology procedures for their World Bank region. In round 2, participants ranked round 1 responses in order of global importance on a 5-point Likert scale. In round 3, participants reranked conditions and procedures that did not achieve consensus, defined as at least 70% of the round 2 Likert responses being ranked as either "important" or "very important." Descriptive statistics were calculated for each round.

RESULTS

The survey was distributed to 35 experts globally, with a 40% (n = 14) response rate. Fifty percent (n = 7) of participants were from low- and middle-income countries, with at least 1 participant from each World Bank region. A list of 28 consensus surgical procedures and 11 consensus conditions were identified.

CONCLUSION

This Delphi survey method of world experts in pediatric otolaryngology identified a core list of medical conditions and surgical procedures that should be a part of every national health system's clinical goals of treatment, research, and capacity building.
