Nationwide survey of middle ear cholesteatoma surgery cases in Japan: Results from the Japan Otological society registry using the JOS staging and classification system

ObjectiveThis study was aimed to determine the characteristics of middle ear cholesteatoma and to investigate short-term outcomes regarding the rates of residual and recurrent cholesteatoma and the postoperative hearing results in Japan, via a nationwide survey using staging and classification criteria for middle ear cholesteatoma, as proposed by the Japan Otological Society (JOS). MethodsThe first-round survey was conducted in 2016. The target was patients with middle ear cholesteatoma who were surgically treated in Japan between January and December 2015. Medical information on the patients was anonymized. The questionnaire entries were age, sex, cholesteatoma classification and stage, preoperative hearing level, mastoid development, status of the stapes, and surgical method. There were a total of 1,787 registered patients from 74 facilities from all over Japan. The second survey was conducted in January 2018 and received 1,456 responses from 49 facilities in Japan. Of the 1,456 cases, 1,060 were conducted in the postoperative hearing survey and 1,084 in the residual recurrence survey. ResultsThe most common cholesteatoma type was pars flaccida cholesteatoma (63.3%), followed by pars tensa cholesteatoma (13.0%), congenital cholesteatoma (12.9%), and cholesteatoma secondary to chronic tensa perforation (5.6%). Cholesteatoma of uncertain origin accounted for 5.0% (90 cases). Stage II was predominant in pars flaccida and pars tensa cholesteatoma, which frequently involves the mastoid, whereas about half of cases of cholesteatoma secondary to chronic tensa perforation and congenital cholesteatoma were classified as stage I. One hundred fifty-two of 1,084 cases (14.0%) had recurrent cholesteatoma, residual cholesteatoma, or both following first surgeries. The postoperative rates of hearing success rate was 63.3%. ConclusionWe were able to clarify not only the current epidemiological status of middle ear cholesteatoma but also the current trends of cholesteatoma surgery in Japan. The development of a staging system by the JOS Committee serving an epidemiological database for international or time-dependent comparison. It is possible to use this staging system with reasonable reliability.

Prioritising target non-pharmacological interventions for research in Parkinson\u2019s disease: achieving consensus from key stakeholders

BackgroundIn 2014 Parkinson’s UK conducted a research prioritisation exercise with stakeholders highlighting important clinical research questions. The exercise highlighted the need for effective interventions to be developed and tested to tackle a range of non-motor symptoms including: sleep quality, stress and anxiety, mild cognitive impairment, dementia and urinary problems. The present work set out to build on this exercise by prioritising types of non-pharmacological interventions to be tested to treat the identified non-motor symptoms.MethodsA Patient and Public Involvement exercise was used to reach consensus on intervention priorities for the treatment of non-motor symptoms. A Delphi structure was used to support the feedback collected. A first-round prioritisation survey was conducted followed by a panel discussion. Nineteen panellists completed the first-round survey (9 people with Parkinson’s and 10 professionals working in Parkinson’s) and 16 participated in the panel discussion (8 people with Parkinson’s and 8 professionals working in Parkinson’s). A second-round prioritization survey was conducted after the panel discussion with 13 people with Parkinson’s.ResultsPhysical activity, third wave cognitive therapies and cognitive training were rated as priority interventions for the treatment of a range of non-motor symptoms. There was broad agreement on intervention priorities between health care professionals and people with Parkinson’s. A consensus was reached that research should focus on therapies which could be used to treat several different non-motor symptoms. In the context of increasing digitisation, the need for human interaction as an intervention component was highlighted.ConclusionBringing together Parkinson’s professionals and people with Parkinson’s resulted in a final treatment priority list which should be both feasible to carry out in routine clinical practice and acceptable to both professionals and people with Parkinson’s. The workshop further specified research priorities in Parkinson’s disease based on the current evidence base, stakeholder preferences, and feasibility. Research should focus on developing and testing non-pharmacological treatments which could be effective across a range of symptoms but specifically focusing on tailored physical activity interventions, cognitive therapies and cognitive training.

The Characteristics Differentiating Expert and Competent Strength and Conditioning Coaches

ABSTRACT Purpose: The purpose of this study was to identify the skills, knowledge, and experiences differentiating expert and competent strength and conditioning (S&C) coaches. Method: The participants were 87 elite-level head S&C coaches with an average of over 18 years of coaching experience. These coaches were employed by teams from the MLB, NBA, NFL, NHL, NCAA Division 1 FBS “Power Five” Conferences, United States National Teams, and the Australian Football League. This study used both a qualitative and quantitative research design through the use of the Delphi method, which incorporated three rounds of surveys. The first-round survey asked the participants to identify at least one important skill, knowledge area, and experience that should be possessed by an expert and competent S&C coach respectively. The characteristics generated from the first round were placed on a second-round survey and rated on their level of importance using a five-point Likert scale. If a characteristic received a suggestion for rephrasing, and did not reach a level of consensus, or an entirely new characteristic was suggested, then it was placed on the final-round survey to be rated again. Characteristics that reached a level of consensus were placed on the final list of characteristics. Results: A total of 46 characteristics reached a level of consensus and were placed on the final list of characteristics. Conclusion: There now exists an empirically validated list of characteristics differentiating expert and competent S&C coaches. This list can aid in the selection, evaluation, and development of S&C coaches.

Development of a return to play checklist following patellar instability surgery: a Delphi-based consensus.

To date, there is no consensus for the appropriate timing or functional evaluation for safe return to play following patellar instability surgery. The purpose of this study is to develop a consensus-based return to play checklist following patellar stabilization surgery using the Delphi method. A 3-part survey series was conducted following the systematic guidelines of the Delphi technique for gathering consensus from experts in the management of patellofemoral instability. All surveys were completed between July and November of 2017. A literature search was performed in SCOPUS and PubMed to identify existing sources on return to play following patellar instability surgery and determining patellofemoral joint strength in athletes, which served as the basis for the surveys. 12 of the 19 selected participants (63%) completed the first-round survey, 11 of those 12 participants (92%) completed the second-round survey, and 10 of these 11 participants (91%) completed the final survey. Of the final ten participants, there was representation from seven different states in the USA. Nine of the ten (90%) respondents endorsed the final checklist. The final checklist included eight overarching domains with defined and reproducible objective criteria. The standardized list of objective and reproducible criteria for rehabilitation outlined below should help practitioners focus more on patient-centred factors and less on arbitrary timelines. No prior study has gathered consensus from experts on this topic; therefore, this study should serve as a benchmark to help guide patients back to sport safely. V.

Stakeholders’ views on the value of outcomes from clinical genetic and genomic interventions

Robust evidence about the value of clinical genomic interventions (CGIs), such as genetic/genomic testing or clinical genetic evaluation, is limited. We obtained stakeholders' perspectives on outcomes from CGIs to help inform their value. We used an adapted Delphi expert panel process. Two anonymous survey rounds assessed the value of 44 CGI outcomes and whether a third party should pay for them, with discussion in between rounds. Sixty-six panelists responded to the first-round survey and 60 to the second. Policy-makers/payers gave the lowest ratings for value and researchers gave the highest. Patients/consumers had the most uncertainty about value and payment by a third party. Uncertainty about value was observed when evidence of proven health benefit was lacking, potential harms outweighed benefits for reproductive outcomes, and outcomes had only personal utility for individuals or family members. Agreement about outcomes for which a third party should not pay included prevention through surgery with unproven health benefits, establishing ancestry, parental consanguinity, and paternity. Research is needed to understand factors contributing to uncertainty and stakeholder differences about the value of CGI outcomes. Reaching consensus will accelerate the creation of metrics to generate the evidence needed to inform value and guide policies that promote availability, uptake, and coverage of CGIs.

Consensus on Severity for Ocular Emergency: The BAsic SEverity Score for Common OculaR Emergencies [BaSe SCOrE

Purpose. To weigh ocular emergency events according to their severity. Methods. A group of ophthalmologists and researchers rated the severity of 86 common ocular emergencies using a Delphi consensus method. The ratings were attributed on a 7-point scale throughout a first-round survey. Then, the experts were provided with the median and quartiles of the ratings of each item to reevaluate the severity levels being aware of the group's first-round responses. The final severity rating for each item corresponded to the median rating provided by the last Delphi round. Results. We invited 398 experts, and 80 (20%) of them, from 18 different countries, agreed to participate. A consensus was reached in the second round, completed by 24 experts (43%). The severity ranged from subconjunctival hemorrhages (median = 1, Q1 = 0; Q3 = 1) to penetrating eye injuries collapsing the eyeball with intraocular foreign body or panophthalmitis with infection following surgery (median = 5, Q1 = 5; Q3 = 6). The ratings did not differ according to the practice of the experts. Conclusion. These ratings could be used to assess the severity of ocular emergency events, to serve in composite algorithms for emergency triage and standardizing research in ocular emergencies.

Prevention and control of major non-communicable diseases in China from 1990 to 2009: results of a two-round Delphi survey

Objective: The aim of this study was to learn about the progress of the prevention and control of major non-communicable diseases (NCDs) in China from 1990 to 2009 and to determine what prevention and control gaps remain based on the opinions of a group of panellists.Design: Sixty-four panellists, who are members of the Subcommittee of the Non-Communicable Diseases, the Expert Committee on Disease Control and Prevention established by China's Ministry of Health in 2010, were invited to participate in an email-based, two-round Delphi survey. In each round, a structured questionnaire was given to participants, who were asked to rate the importance and practical implementation of items relevant to the prevention and control of NCDs over two periods, 1990–1999 and 2000–2009, on a 10-point scale.Results: Of the 64 panellists invited, 20 (31.3%) completed the first-round survey, and, of those, 14 (70.0%) completed the second-round survey. Of the 237 common variables in the two survey rounds, there were 161 (67.9%) and 209 (88.2%) with an interquartile range ≤2 in the first round and second round, respectively. These results indicated a better expert consensus in the second round. There were 92 items in total in the second round of the questionnaire, 88 (95.7%) of which had median importance rating scores of equal to or greater than 7.00. The median scores for the practical implementation items during 2000–2009 were greater than those for the 1990–1999 period. The results indicate improved implementation in the recent decade.Conclusions: China has made progress in the prevention and control of NCDs during the 21st century. However, these intuitive rating results indicate that there are still large action gaps in the fight against epidemic NCDs in China.To access the supplementary material to this article please see Supplementary files under Article Tools online.

A two-round Delphi study examining consensus of recommended clinical practices for patients with ventricular assist devices as destination therapy

To identify the current clinical practices of Medicare-certified facilities offering ventricular assist devices as destination therapy and to attain a consensus of recommended clinical practices across the United States for the management of adults with ventricular assist devices as destination therapy. Sixty ventricular assist device coordinators from Medicare-certified centers were invited to participate in an online, 2-round Delphi survey. The surveys asked whether recommended practices are current practices and whether respondents always/agreed or never/disagreed with performing the recommended practice guidelines. Consensus was defined as 75% agreement. The clinical areas of focus were patient selection, preoperative preparation, postoperative care, infection control, nutrition, and patient discharge preparation. Practices were extracted from the advanced practice guidelines for HeartMate destination therapy and the International Society for Heart and Lung Transplantation's 2006 guidelines for the care of heart transplant candidates. Representing 21 states across the country, the first-round survey had a response rate of 57% (n = 34). The second-round survey had a response rate of 74% (n = 17), representing 28% of the 60 centers. Consensus was obtained for 122 practices. The dimension of patient selection-diagnostic tests and screening had the highest level of consensus (16%, n = 20), and the dimension of postoperative care-intermediate/intensive care unit dimension had the lowest level of consensus (3.3%, n = 4). Survey results identify a consensus of practices for the specific group of ventricular assist device coordinators who responded, but that consensus cannot be generalized to all ventricular assist device facilities. These results can, however, provide a foundation for further research leading to the development of standard-of-care practices for patients with ventricular assist devices as destination therapy.

Development of a Standard for Hospital-Based Palliative Care Consultation Teams Using a Modified Delphi Method

Although palliative care consultation teams are rapidly being disseminated throughout Japan as a result of government policy, the role of these teams has not been standardized. The aim of this study was to develop a hospital-based palliative care consultation team standard. We adopted a modified Delphi method to develop a standard. Twenty-seven multiprofessional panelists were selected according to two criteria: adequate experience as part of a palliative care consultation team and representative of 16 palliative care-related organizations. Panelists rated the appropriateness of 33 statements in a provisional standard, which was generated by the authors, using a nine-point Likert-type scale in a first-round survey. We set two criteria for agreement: the median value was 8 or more, and the difference between the minimum and maximum was 4 or less. There were 15 disagreements in the first-round survey. Based on discussions through e-mails and a panel meeting, these 15 statements were dealt with as follows: one was rejected, one was combined with another statement, three were unmodified, and 10 underwent minor revisions. Moreover, two statements that generated agreement were divided into two statements each. Consequently, the number of statements was 37. In a second-round survey, three statements engendered disagreement and were modified. At the end of the process, there were 37 statements in four areas: “philosophy and policy,” “structure for care provision,” “contents of activities,” and “quality assurance and care improvements.” This standard may be useful as a clinical activity guide as well as a method to evaluate palliative care consultation teams.

Experts' opinions on the role of liver biopsy in HCV infection: A Delphi survey by the Italian Association of Hospital Gastroenterologists (A.I.G.O.)

Liver biopsy represents the gold standard to establish a diagnosis in all liver patients, but its current position in chronic viral hepatitis is questioned. We aimed to create a consensus on best practice of use of liver biopsy in the management of chronic HCV infection. We applied the Delphi method to 12 clinical scenarios of chronic HCV infection, to assess the extent of agreement (consensus measurement) and to resolve disagreement (consensus development) on the appropriateness of liver biopsy. Among 108 chosen hepatologists, 61 (56.5%) accepted to participate to the first-round survey. In four patients the majority of experts (from 61.4 to 86.2%) agreed not to perform liver biopsy; in two cases an equivalent opinion was found, and in the remaining six scenarios the majority of experts would have recommended a biopsy. No expert recommended liver biopsy in all cases, while most agreed for an histological evaluation of 4 to 8 cases. At the second round, 36 experts (59%) submitted ballots. Fifty-four out of 431 (12.6%) original judgments were changed with equal distribution among different scenarios. Our survey showed a great divergence of management of similar patients and should provide a stimulus for an evidence-based evaluation of liver histology in chronic HCV infection.
