Lung cancer (internet-based) Delphi (LUCiD): A modified eDelphi consensus process to establish Australasian clinical quality indicators for thoracic cancer.

BACKGROUND AND OBJECTIVE: Approximately 16,000 new cases of lung cancer are diagnosed each year in Australia and Aotearoa New Zealand, and it is the leading cause of cancer death in the region. Unwarranted variation in lung cancer care and outcomes has been described for many years, although clinical quality indicators to facilitate benchmarking across Australasia have not been established. The purpose of this study was to establish clinical quality indicators applicable to lung and other thoracic cancers across Australia and Aotearoa New Zealand. METHODS: Following a literature review, a modified three round eDelphi consensus process was completed between October 2022 and June 2023. Participants included clinicians from all relevant disciplines, patient advocates, researchers and other stakeholders, with representatives from all Australian states and territories and Aotearoa New Zealand. Consensus was set at a threshold of 70%, with the first two rounds conducted as online surveys, and the final round held as a hybrid in person and virtual consensus meeting. RESULTS: The literature review identified 422 international thoracic oncology indicators, and a total of 71 indicators were evaluated over the course of the Delphi consensus. Ultimately, 27 clinical quality indicators reached consensus, covering the continuum of thoracic oncologic care from diagnosis to first line treatment. Indicators benchmarking supportive care were poorly represented. Attendant numeric quality standards were developed to facilitate benchmarking. CONCLUSION: Twenty-seven clinical quality indicators relevant to thoracic oncology care in Australasia were developed. Real world implementation will now be explored utilizing a prospective dataset collected across Australia.

International Classification System for Ocular Complications of Anti-VEGF Agents in Clinical Trials.

PURPOSE: Complications associated with intravitreal anti-VEGF therapies are reported inconsistently in the literature, thus limiting an accurate evaluation and comparison of safety between studies. This study aimed to develop a standardized classification system for anti-VEGF ocular complications using the Delphi consensus process. DESIGN: Systematic review and Delphi consensus process. PARTICIPANTS: Twenty-five international retinal specialists participated in the Delphi consensus survey. METHODS: A systematic literature search was conducted to identify complications of intravitreal anti-VEGF agent administration based on randomized controlled trials (RCTs) of anti-VEGF therapy. A comprehensive list of complications was derived from these studies, and this list was subjected to iterative Delphi consensus surveys involving international retinal specialists who voted on inclusion, exclusion, rephrasing, and addition of complications. Furthermore, surveys determined specifiers for the selected complications. This iterative process helped to refine the final classification system. MAIN OUTCOME MEASURES: The proportion of retinal specialists who choose to include or exclude complications associated with anti-VEGF administration. RESULTS: After screening 18 229 articles, 130 complications were categorized from 145 included RCTs. Participant consensus via the Delphi method resulted in the inclusion of 91 complications (70%) after 3 rounds. After incorporating further modifications made based on participant suggestions, such as rewording certain phrases and combining similar terms, 24 redundant complications were removed, leaving a total of 67 complications (52%) in the final list. A total of 14 complications (11%) met exclusion thresholds and were eliminated by participants across both rounds. All other remaining complications not meeting inclusion or exclusion thresholds also were excluded from the final classification system after the Delphi process terminated. In addition, 47 of 75 proposed complication specifiers (63%) were included based on participant agreement. CONCLUSIONS: Using the Delphi consensus process, a comprehensive, standardized classification system consisting of 67 ocular complications and 47 unique specifiers was established for intravitreal anti-VEGF agents in clinical trials. The adoption of this system in future trials could improve consistency and quality of adverse event reporting, potentially facilitating more accurate risk-benefit analyses.

Diagnosis of methamphetamine-induced psychotic disorder: Findings of an expert consensus panel.

AIM: We define criteria for methamphetamine-induced psychotic disorder (MIPD) to aid in accurate and reliable diagnosis. METHOD: An expert panel was recruited and engaged in an iterative consensus process. A literature search supported this work. The a priori level for consensus was considered ≥80% of voting panellists. RESULTS: The final expert panel included 22 physicians from different backgrounds and practice environments. The panel produced two consensus diagnoses: (1) acute MIPD and (2) persisting MIPD, which is further separated into subacute and chronic timeframes. Although certain characteristics differentiate methamphetamine-induced psychosis shortly after use, identification of persisting MIPD depends largely on a history of symptom onset. All respondents voted in the final round, and both criteria were fully endorsed by 91% (20/22) of respondents. Panellists further recommended next steps in validation and research on this topic. CONCLUSION: These diagnostic criteria aid clinicians in differentiating methamphetamine-induced psychotic symptoms from psychosis because of other psychiatric disorders and can guide future studies. Future research might examine these criteria's prognostic significance, interrater reliability and acceptability including among persons in recovery. This work is a necessary and vital step in advancing the science of methamphetamine addiction treatment.

Management of psoriatic arthritis: a consensus opinion by expert rheumatologists.

Background: Psoriatic arthritis (PsA) is a chronic inflammatory musculoskeletal disease involving several articular and extra-articular structures. Despite the important progresses recently made in all of the aspects of this disease, its management is still burdened by unresolved issues. The aim of this exercise was to provide a set of statements that may be helpful for the management of PsA. Methods: A group of 38 Italian rheumatologists with recognized expertise in PsA selected and addressed the following four topics: "early PsA," "axial-PsA," "extra-articular manifestations and comorbidities," "therapeutic goals." Relevant articles from the literature (2016-2022) were selected by the experts based on a PubMed search. A number of statements for each topic were elaborated. Results: Ninety-four articles were selected and evaluated, 68 out of the 1,114 yielded by the literature search and 26 added by the Authors. Each of the four topic was subdivided in themes as follows: transition from psoriasis to PsA, imaging vs. CASPAR criteria in early diagnosis, early treatment for "early PsA"; axial-PsA vs. axialspondyloarthritis, diagnosis, clinical evaluation, treatment, standard radiography vs. magnetic resonance imaging for "axial PsA"; influence of inflammatory bowel disease on the therapeutic choice, cardiovascular comorbidity, bone damage, risk of infection for "comorbidities and extra-articular manifestations"; target and tools, treat-to-target strategy, role of imaging for "therapeutic goals." The final document consisted of 49 statements. Discussion: The final product of this exercise is a set of statements concerning the main issues of PsA management offering an expert opinion for some unmet needs of this complex disease.

Impacts of public health and social measures on COVID-19 in Europe: a review and modified Delphi technique.

Introduction: The emergence of the COVID-19 pandemic in early 2020 led countries to implement a set of public health and social measures (PHSMs) attempting to contain the spread of the SARS-CoV-2 virus. This study aims to review the existing literature regarding key results of the PHSMs that were implemented, and to identify the PHSMs considered to have most impacted the epidemiological curve of COVID-19 over the last years during different stages of the pandemic. Methods: The PHSM under study were selected from the Oxford COVID-19 Government Response Tracker (OxCGRT), supplemented by topics presented during the Rapid Exchange Forum (REF) meetings in the scope of the Population Health Information Research Infrastructure (PHIRI) project (H2020). The evidence- based review was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines to identify which reviews have already been published about each PHSMs and their results. In addition, two modified Delphi panel surveys were conducted among subject matter experts from 30 European countries to uphold the results found. Results: There were 3,212 studies retrieved from PubMed, 162 full texts assessed for eligibility and 35 included in this PHSMs summary. The measures with clearest evidence on their positive impact from the evidence-based review include social distancing, hygiene measures, mask measures and testing policies. From the modified Delphi panel, the PHSMs considered most significant in the four periods analyzed were case isolation at home, face coverings, testing policy, and social distancing, respectively. Discussion: The evidence found has significant implications for both researchers and policymakers. The study of PHSMs' impact on COVID-19 illustrates lessons learned for future pan- and epidemics, serving as a contribution to the health systems resilience discussion. These lessons, drawn from both the available scientific evidence and the perspectives of relevant subject matter experts, should also be considered in educational and preparedness programs and activities in the public health space.

Prioritizing risk factors and identifying target areas to address with interventions to improve sustainable employment of persons with a brain injury or a spinal cord injury - A multi-stakeholder consensus process.

Background: Achieving sustainable long-term employment is the goal of work integration for persons with acquired brain injury (ABI) or spinal cord injury (SCI). However, decreasing employment rates over time for persons with ABI and SCI indicate that remaining employed in the long-term is a challenge. Purpose: To identify the most important risk factors that pose a barrier to sustainable employment of persons with ABI or SCI from a multi-stakeholder perspective, and to propose corresponding interventions that address them. Methods: Multi-stakeholder consensus conference and follow-up survey. Results: From 31 risk factors to sustainable employment of persons with ABI or SCI identified in previous studies, nine were defined as most important to address with interventions. These risk factors either impacted the person, the work environment or service provision. Potential interventions to address these factors were proposed in mixed condition groups, of which ten were voted on as priority interventions. The follow-up survey revealed strong agreement on the intervention proposals, strong to moderate agreement on impact, but moderate to low feasibility, as most of the interventions were measures at the meso- (service) and macro- (legislation and state regulation) level. Conclusions: Holding micro-level stakeholder conferences is a valuable method for identifying the most important risk factors to sustainable employment and for developing measures to address them. To implement measures that involve decisions at the meso- or macro-level, representatives from these levels of the healthcare and social system have to be involved.

Prevention and Treatment of Chemotherapy-Induced Peripheral Neuropathy (CIPN) with Non-Pharmacological Interventions: Clinical Recommendations from a Systematic Scoping Review and an Expert Consensus Process.

Background: Most individuals affected by cancer who are treated with certain chemotherapies suffer of CIPN. Therefore, there is a high patient and provider interest in complementary non-pharmacological therapies, but its evidence base has not yet been clearly pointed out in the context of CIPN. Methods: The results of a scoping review overviewing the published clinical evidence on the application of complementary therapies for improving the complex CIPN symptomatology are synthesized with the recommendations of an expert consensus process aiming to draw attention to supportive strategies for CIPN. The scoping review, registered at PROSPERO 2020 (CRD 42020165851), followed the PRISMA-ScR and JBI guidelines. Relevant studies published in Pubmed/MEDLINE, PsycINFO, PEDro, Cochrane CENTRAL, and CINAHL between 2000 and 2021 were included. CASP was used to evaluate the methodologic quality of the studies. Results: Seventy-five studies with mixed study quality met the inclusion criteria. Manipulative therapies (including massage, reflexology, therapeutic touch), rhythmical embrocations, movement and mind-body therapies, acupuncture/acupressure, and TENS/Scrambler therapy were the most frequently analyzed in research and may be effective treatment options for CIPN. The expert panel approved 17 supportive interventions, most of them were phytotherapeutic interventions including external applications and cryotherapy, hydrotherapy, and tactile stimulation. More than two-thirds of the consented interventions were rated with moderate to high perceived clinical effectiveness in therapeutic use. Conclusions: The evidence of both the review and the expert panel supports a variety of complementary procedures regarding the supportive treatment of CIPN; however, the application on patients should be individually weighed in each case. Based on this meta-synthesis, interprofessional healthcare teams may open up a dialogue with patients interested in non-pharmacological treatment options to tailor complementary counselling and treatments to their needs.

Development of consensus on essential virtues for ethics and research integrity training using a modified Delphi approach.

Most ethics and research integrity (ERI) training approaches are based on teaching moral rules, duties or responsibilities, often not sufficiently addressing virtue-based ethics. This study aimed to obtain a consensus among relevant experts on the importance of essential virtues for ERI training and their acquisitions. A modified Delphi consensus process was conducted in three rounds; 31 ERI experts participated in Round 1 and 23 in Round 2 and Round 3. Based on findings generated from qualitative data in Round 1, a structured questionnaire with 90 different statements grouped under five domains was developed for Round 2 and Round 3. After the final round, a consensus was achieved on two-thirds of statements included in this study. The experts agreed that virtues are based on learned and reflected attitudes and that the appropriate direction to acquire research virtues is through continuing education using case studies and discussions based on real-life scenarios. Furthermore, the consensus was obtained on 35 scientific virtues that should be stimulated in ERI training, prioritizing honesty, integrity, accountability, criticism and fairness as the most essential scientific virtues for good research practice. These results should be considered in developing or adjusting the ERI training program and materials.

Evidence-based indicators for the measurement of quality of primary care using health insurance claims data in Switzerland: update of the SQUIPRICA working group.

BACKGROUND: The level of quality of care of ambulatory services in Switzerland is almost completely unknown. Since health insurance claims are the only nationwide applicable and available data source for this purpose, a set of 24 quality indicators (QI) for the measurement of quality of primary care has been previously developed and implemented. The present paper reports on an evidence-based update and extension of the initial QI set. METHODS: Established pragmatic 6-step process based on informal consensus and potential QI extracted from international medical practice guidelines and pre-existing QI for primary care. Experts rated potential QI based on strength of evidence, relevance for Swiss public health, and controllability in the Swiss primary care context. Feasibility of a preliminary set of potential new QI was tested using claims data of persons with basic mandatory health insurance at one of the largest Swiss health insurers. This test built the basis for expert consensus on the final set of new QI. Additionally, two diabetes indicators included in the previous QI set were re-evaluated. RESULTS: Of 23 potential new indicators, 19 of them were selected for feasibility testing. The expert group consented a final set of 9 additional QI covering the domains general aspects/efficiency (2 QI), diagnostic measures (1 QI), geriatric care (2 QI), osteoarthritis (1 QI), and drug safety (3 QI). Two pre-existing diabetes indicators were updated. CONCLUSIONS: Additional QI relating to overuse and intersectoral care aspects extend the options of measuring quality of primary care in Switzerland based on claims data and complement the initial QI set.

Integrating Key Nursing Measures into a Comprehensive Healthcare Performance Management System: A Tuscan Experience.

This paper addresses the evaluation of nursing quality and safety beyond nursing tasks in specific healthcare settings and sets it in a context that conveys the sense of complexity and multifaceted nature of the contribution that nursing makes to the whole system. The paper describes research conducted in Tuscany during 2019 involving regional managers and heads of nursing departments. This research has led to the development of an integrated evaluation framework through focus groups and consensus process with the latter, which includes Performance Organizational climate data, Patient-Reported Experience Measures (PREMs), and Patient-Reported Outcome Measures (PROMs). This integrated framework aims at both making sense of extant measures as key performance indicators shared among different professionals while recognizing the important role of nursing care by adding specific measures and can be seen as a tool that boosts the sense of "teamness" in healthcare.

Identification and Assessment of Strategies to Address Gender Inequity in the Specialty of Critical Care Medicine: A Scoping Review, Modified Consensus Process, and Stakeholder Meeting.

We sought to identify and prioritize improvement strategies that Critical Care Medicine (CCM) programs could use to inform and advance gender equity among physicians in CCM. DESIGN: This study involved three sequential phases: 1) scoping review that identified strategies to improve gender equity in all medical specialties; 2) modified consensus process with 48 CCM stakeholders to rate and rank identified strategies; and 3) in-person stakeholder meeting to refine strategies and discuss facilitators and barriers to their implementation. SETTING: CCM. SUBJECTS: CCM stakeholders (physicians, researchers, and decision-makers; mutually inclusive). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We identified 190 unique strategies from 416 articles. Strategies were grouped thematically into 20 categories across four overarching pillars of equity: access, participation, reimbursement, and culture. Participants prioritized 22 improvement strategies for implementation in CCM. The top-rated strategy from each pillar included: 1) nominate gender diverse candidates for faculty positions and prestigious opportunities (equitable access); 2) mandate training in unconscious bias and equitable treatment for committee (e.g., hiring, promotion) members (equitable participation); 3) ensure equitable starting salaries regardless of sex or gender (equitable reimbursement); and, 4) conduct 360° evaluations of leaders (including their direct work circle of supervisors, peers, and subordinates) through a diversity lens (equitable culture). Interprofessional collaboration, leadership, and local champions were identified as key enablers for implementation. CONCLUSIONS: We identified stakeholder-prioritized strategies that can be used to inform and enhance gender equity among physicians in CCM under four overarching equity pillars: access, participation, reimbursement, and culture. Implementation approaches should include education, policy creation, and measurement, and reporting.

A Modified Delphi Process to Prioritize Experiences and Guidance Related to ICU Restricted Visitation Policies During the Coronavirus Disease 2019 Pandemic.

To create evidence-based consensus statements for restricted ICU visitation policies to support critically ill patients, families, and healthcare professionals during current and future pandemics. DESIGN: Three rounds of a remote modified Delphi consensus process. SETTING: Online survey and virtual polling from February 2, 2021, to April 8, 2021. SUBJECTS: Stakeholders (patients, families, clinicians, researchers, allied health professionals, decision-makers) admitted to or working in Canadian ICUs during the coronavirus disease 2019 pandemic. MEASUREMENTS AND MAIN RESULTS: During Round 1, key stakeholders used a 9-point Likert scale to rate experiences (1-not significant, 9-significant impact on patients, families, healthcare professionals, or patient- and family-centered care) and strategies (1-not essential, 9-essential recommendation for inclusion in the development of restricted visitation policies) and used a free-text box to capture experiences/strategies we may have missed. Consensus was achieved if the median score was 7-9 or 1-3. During Round 2, participants used a 9-point Likert scale to re-rate experiences/strategies that did not meet consensus during Round 1 (median score of 4-6) and rate new items identified in Round 1. During Rounds 2 and 3, participants ranked items that reached consensus by order of importance (relative to other related items and experiences) using a weighted ranking system (0-100 points). Participants prioritized 11 experiences (e.g., variability of family's comfort with technology, healthcare professional moral distress) and developed 21 consensus statements (e.g., communicate policy changes to the hospital staff before the public, permit visitors at end-of-life regardless of coronavirus disease 2019 status, creating a clear definition for end-of-life) regarding restricted visitation policies. CONCLUSIONS: We have formulated evidence-informed consensus statements regarding restricted visitation policies informed by diverse stakeholders, which could enhance patient- and family-centered care during a pandemic.

Quality Indicators for Avalanche Victim Management and Rescue.

Decisions in the management and rescue of avalanche victims are complex and must be made in difficult, sometimes dangerous, environments. Our goal was to identify indicators for quality measurement in the management and rescue of avalanche victims. The International Commission for Mountain Emergency Medicine (ICAR MedCom) convened a group of internal and external experts. We used brainstorming and a five-round modified nominal group technique to identify the most relevant quality indicators (QIs) according to the National Quality Forum Measure Evaluation Criteria. Using a consensus process, we identified a set of 23 QIs to measure the quality of the management and rescue of avalanche victims. These QIs may be a valuable tool for continuous quality improvement. They allow objective feedback to rescuers regarding clinical performance and identify areas that should be the foci of further quality improvement efforts in avalanche rescue.

Development and Content Validation of a Multidisciplinary Standardized Management Pathway for Hypoxemic Respiratory Failure and Acute Respiratory Distress Syndrome.

OBJECTIVES: Treatment of hypoxemic respiratory failure and acute respiratory distress syndrome is complex. Evidence-based therapies that can improve survival and guidelines advocating their use exist; however, implementation is inconsistent. Our objective was to develop and validate an evidence-based, stakeholder-informed standardized management pathway for hypoxemic respiratory failure and acute respiratory distress syndrome to improve adherence to best practice. DESIGN: A standardized management pathway was developed using a modified Delphi consensus process with a multidisciplinary group of ICU clinicians. The proposed pathway was externally validated with a survey involving multidisciplinary stakeholders and clinicians. SETTING: In-person meeting and web-based surveys of ICU clinicians from 17 adult ICUs in the province of Alberta, Canada. INTERVENTION: Not applicable. MEASUREMENTS AND MAIN RESULTS: The consensus panel was comprised of 30 ICU clinicians (4 nurses, 10 respiratory therapists, 15 intensivists, 1 nurse practitioner; median years of practice 17 [interquartile range, 13-21]). Ninety-one components were serially rated and revised over two rounds of online and one in-person review. The final pathway included 46 elements. For the validation survey, 692 responses (including 59% nurses, 33% respiratory therapists, 7% intensivists and 1% nurse practitioners) were received. Agreement of greater than 75% was achieved on 43 of 46 pathway elements. CONCLUSIONS: A 46-element evidence-informed hypoxemic respiratory failure and acute respiratory distress syndrome standardized management pathway was developed and demonstrated to have content validity.

Development of the Advanced Encryption Standard.

Strong cryptographic algorithms are essential for the protection of stored and transmitted data throughout the world. This publication discusses the development of Federal Information Processing Standards Publication (FIPS) 197, which specifies a cryptographic algorithm known as the Advanced Encryption Standard (AES). The AES was the result of a cooperative multiyear effort involving the U.S. government, industry, and the academic community. Several difficult problems that had to be resolved during the standard's development are discussed, and the eventual solutions are presented. The author writes from his viewpoint as former leader of the Security Technology Group and later as acting director of the Computer Security Division at the National Institute of Standards and Technology, where he was responsible for the AES development.

The development of a modified comprehensive geriatric assessment for use in the emergency department using a RAND/UCLA appropriateness method.

BACKGROUND: The universal screening and comprehensive assessment of older persons presenting to the emergency department is considered useful, yet is difficult to embed. A number of assessment instruments exist however they are not widely used and there is a lack of agreement between clinicians as to which tools are best suited to the emergency department. The aim of this study was to develop a modified comprehensive geriatric assessment using consensus methodology for use by the multidisciplinary team in the emergency department. METHOD: The modified comprehensive geriatric assessment was formulated using the RAND/UCLA appropriateness methodology incorporating consensus opinion from an expert group of clinicians and the best scientific evidence available. A series of pre and post survey and expert group meetings were held with expert multidisciplinary clinicians. Emphasis was placed on a pragmatic approach to the development of a document which reflected consensus opinion. RESULTS: Between nine and 15 expert group members participated in the stages of the process. A tiered approach incorporating different aspects of screening and/or assessments was considered optimal to reflect the stages of decision-making in the emergency department process. CONCLUSION: A unique approach to the screening and assessment of the frail older person was developed using consensus methodology to develop a modified comprehensive geriatric assessment for use in the emergency department. Associated actions and interventions are an important next step, with pilot site testing.

Stakeholder Generated Ideas for Alternative School Food Provision Models in Australia Using the Nominal Group Technique.

Good nutrition is important for children's learning, growth, and development, yet food intake during school hours does not align with recommendations. In Australia, most school children currently bring a packed lunch from home, but what if there was a different way? This project aimed to engage a diverse range of stakeholders to (1) generate, refine and prioritize ideas for novel models of food provision to Australian children within school hours, and (2) to determine and rank the potential barriers and facilitators to changing the school food provision system. This study used nominal group technique virtual workshops-three idea generation workshops (n = 21 participants) and one consensus workshop (n = 11 participants). School lunch prepared onsite was the top ranked food provision model option based on impact and achievability. Potential barriers (n = 26) and facilitators (n = 28) to changing the school food system were generated. The top ranked barrier and facilitator related to government support. This study highlights that there is an opportunity to explore partnerships and utilize existing skills and infrastructure to introduce a universal school-provided lunch model in Australia. The next steps should focus on building the business case capturing the social value of investing in school lunches, including considering parent-paid and subsidized options.

'It just wasn't going to be heard': A mixed methods study to compare different ways of involving people with diabetes and health-care professionals in health intervention research.

BACKGROUND: Guidelines recommend involving intervention users in the intervention development process. However, there is limited guidance on how to involve users in a meaningful and effective way. OBJECTIVE: The aim of this Study within a trial was to compare participants' experiences of taking part in one of three types of consensus meetings-people with diabetes-only, combined people with diabetes and health-care professionals (HCPs) or HCP-only meeting. DESIGN: The study used a mixed methods convergent design. Quantitative (questionnaire) and qualitative (observation notes and semi-structured telephone interviews) data were collected to explore participants' experiences. A triangulation protocol was used to compare quantitative and qualitative findings. PARTICIPANTS: People with diabetes (recruited via multiple strategies) were randomly assigned to attend the people with diabetes or combined meeting. HCPs (recruited through professional networks) attended the HCP or combined meeting based on their availability. RESULTS: Sixteen people with diabetes and 15 HCPs attended meetings, of whom 18 participated in a telephone interview. Participants' questionnaire responses suggested similar positive experiences across the three meetings. Observation and semi-structured interviews highlighted differences experienced by participants in the combined meeting relating to: perceived lack of common ground; feeling empowered versus undervalued; needing to feel safe and going off task to fill the void. CONCLUSIONS: The qualitative theme 'needing to feel safe' may explain the dissonance (disagreement) between quantitative and qualitative data. In this study, involving patients and HCPs simultaneously in a consensus process was not found to be as suitable as involving each stakeholder group separately.

Funnel plots and choropleth maps in cancer risk communication: a Delphi study.

BACKGROUND: In the last decades, the issues related to health risk communication to stakeholders and citizens involving health care practitioners and local political authorities have been increasingly debated. The study evaluated an alternative strategy to communicate cancer risk to local communities, involving an expert panel of public health operators in comparing two different graphic tools, Funnel Plot and Choropleth map. STUDY DESIGN: A Delphi method process was implemented to achieve a unified consensus on an expert panel of public health operators with regard to weaknesses and strengths of the Funnel Plot and the Choropleth map as tools for cancer risk communication to local communities and other stakeholders. METHODS: Participants were asked to score the efficacy of the two tools using a scale. Six properties were explored through two consecutive consensus rounds. Scales were used to calculate frequencies and the content validity ratio for each domain within the consensus rounds. RESULTS: After the two consecutive rounds, participants expressed their preference in favour of the Choropleth map for its ability to define the spatial location of the risk and to locate any potential cluster, while reaching a consensus with regard to the Funnel Plot properties to identify hot spots, displaying the scope of the phenomenon under investigation, and to show the precision of estimates and communicating the significance of estimates. CONCLUSIONS: The Delphi process allowed us to conclude that Funnel Plot could be used as a complement to the current and commonly used graphical and visual formats to effectively communicate cancer epidemiological data to communities and local authorities, representing a useful tool for empowering the general population.

Optimisation: defining and exploring a concept to enhance the impact of public health initiatives.

BACKGROUND: Repeated, data-driven optimisation processes have been applied in many fields to rapidly transform the performance of products, processes and interventions. While such processes may similarly be employed to enhance the impact of public health initiatives, optimisation has not been defined in the context of public health and there has been little exploration of its key concepts. METHODS: We used a modified, three-round Delphi study with an international group of researchers, public health policy-makers and practitioners to (1) generate a consensus-based definition of optimisation in the context of public health and (2i) describe key considerations for optimisation in that context. A pre-workshop literature review and elicitation of participant views regarding optimisation in public health (round 1) were followed by a daylong workshop and facilitated face-to-face group discussions to refine the definition and generate key considerations (round 2); finally, post-workshop discussions were undertaken to refine and finalise the findings (round 3). A thematic analysis was performed at each round. Study findings reflect an iterative consultation process with study participants. RESULTS: Thirty of 33 invited individuals (91%) participated in the study. Participants reached consensus on the following definition of optimisation in public health: "A deliberate, iterative and data-driven process to improve a health intervention and/or its implementation to meet stakeholder-defined public health impacts within resource constraints". A range of optimisation considerations were explored. Optimisation was considered most suitable when existing public health initiatives are not sufficiently effective, meaningful improvements from an optimisation process are anticipated, quality data to assess impacts are routinely available, and there are stable and ongoing resources to support it. Participants believed optimisation could be applied to improve the impacts of an intervention, an implementation strategy or both, on outcomes valued by stakeholders or end users. While optimisation processes were thought to be facilitated by an understanding of the mechanisms of an intervention or implementation strategy, no agreement was reached regarding the best approach to inform decisions about modifications to improve impact. CONCLUSIONS: The study findings provide a strong basis for future research to explore the potential impact of optimisation in the field of public health.
