Project description:BackgroundFinancial ties between health professionals and industry may unduly influence professional judgments and some researchers have suggested that widening disease definitions may be one driver of over-diagnosis, bringing potentially unnecessary labeling and harm. We aimed to identify guidelines in which disease definitions were changed, to assess whether any proposed changes would increase the numbers of individuals considered to have the disease, whether potential harms of expanding disease definitions were investigated, and the extent of members' industry ties.Methods and findingsWe undertook a cross-sectional study of the most recent publication between 2000 and 2013 from national and international guideline panels making decisions about definitions or diagnostic criteria for common conditions in the United States. We assessed whether proposed changes widened or narrowed disease definitions, rationales offered, mention of potential harms of those changes, and the nature and extent of disclosed ties between members and pharmaceutical or device companies. Of 16 publications on 14 common conditions, ten proposed changes widening and one narrowing definitions. For five, impact was unclear. Widening fell into three categories: creating "pre-disease"; lowering diagnostic thresholds; and proposing earlier or different diagnostic methods. Rationales included standardising diagnostic criteria and new evidence about risks for people previously considered to not have the disease. No publication included rigorous assessment of potential harms of proposed changes. Among 14 panels with disclosures, the average proportion of members with industry ties was 75%. Twelve were chaired by people with ties. For members with ties, the median number of companies to which they had ties was seven. Companies with ties to the highest proportions of members were active in the relevant therapeutic area. Limitations arise from reliance on only disclosed ties, and exclusion of conditions too broad to enable analysis of single panel publications.ConclusionsFor the common conditions studied, a majority of panels proposed changes to disease definitions that increased the number of individuals considered to have the disease, none reported rigorous assessment of potential harms of that widening, and most had a majority of members disclosing financial ties to pharmaceutical companies.

Project description:OBJECTIVES:To determine the relationship between manufacturer-related financial ties among investigators of published drug trials and rates of discrepant registered and published primary trial outcomes. DESIGN:Cross-sectional study. SETTING:Human subjects drug trials published in 'core clinical' MEDLINE journals in 2013. PRIMARY AND SECONDARY OUTCOME MEASURES:The primary study endpoint was the presence of a prospectively registered, clearly defined primary outcome that matched the published primary outcome for each included trial. Secondary outcomes included assessments of registration timing and quality, and the impact of outcome discrepancies between registration and publication on the statistical significance of the included trials. RESULTS:Of 192 included trials, 134 (70%) were positive and 58 (30%) were negative. Financial ties were present between first or last authors and drug manufacturers for 130 trials (68%), of which 78% were positive, versus 53% of trials with no financial ties that were positive. Clearly defined, prospectively registered outcomes that matched the published outcomes were present in just 76 of the 192 trials (40%). After adjusting for study start date and sample size, the observed relationship between investigator financial ties and the presence of a match between prospectively registered and published primary outcomes was of borderline statistical significance (OR 2.12, 95% CI 0.998 to 4.50). Studies with financial ties present were more likely than studies without ties to have been prospectively registered (78%vs48%, P<0.001) and were more likely to have prospectively registered a clearly defined primary outcome(62%vs35%, P<0.001). CONCLUSIONS:Less than half of the trials in this cohort were prospectively registered with a clear primary outcome that was consistent with the primary outcome reported in the published manuscript. The presence of investigator financial ties was associated with higher quality registration practices, though this association diminished after adjusting for factors that impact registration quality.
Project description:We examined the relationship between the tobacco industry and the journal Regulatory Toxicology and Pharmacology (RTP) using the Truth Tobacco Industry Documents Library and internet sources. We determined the funding relationships, and categorised the conclusions of all 52 RTP papers on tobacco or nicotine between January 2013 and June 2015, as "positive", "negative" or "neutral" for the tobacco industry. RTP's editor, 57% (4/7) of associate editors and 37% (14/38) of editorial board members had worked or consulted for tobacco companies. Almost all (96%, 50/52) of the papers had authors with tobacco industry ties. Seventy-six percent (38/50) of these papers drew conclusions positive for industry; none drew negative conclusions. The two papers by authors not related to the tobacco industry reached conclusions negative to the industry (p < .001). These results call into question the confidence that members of the scientific community and tobacco product regulators worldwide can have in the conclusions of papers published in RTP.
Project description:OBJECTIVE:To investigate the nature and extent of financial relationships between leaders of influential professional medical associations in the United States and pharmaceutical and device companies. DESIGN:Cross sectional study. SETTING:Professional associations for the 10 costliest disease areas in the US according to the US Agency for Healthcare Research and Quality. Financial data for association leadership, 2017-19, were obtained from the Open Payments database. POPULATION:328 leaders, such as board members, of 10 professional medical associations: American College of Cardiology, Orthopaedic Trauma Association, American Psychiatric Association, Endocrine Society, American College of Rheumatology, American Society of Clinical Oncology, American Thoracic Society, North American Spine Society, Infectious Diseases Society of America, and American College of Physicians. MAIN OUTCOME MEASURES:Proportion of leaders with financial ties to industry in the year of leadership, the four years before and the year after board membership, and the nature and extent of these financial relationships. RESULTS:235 of 328 leaders (72%) had financial ties to industry. Among 293 leaders who were medical doctors or doctors of osteopathy, 235 (80%) had ties. Total payments for 2017-19 leadership were almost $130m (£103m; €119m), with a median amount for each leader of $31 805 (interquartile range $1157 to $254 272). General payments, including those for consultancy and hospitality, were $24.8m and research payments were $104.6m-predominantly payments to academic institutions with association leaders named as principle investigators. Variation was great among the associations: median amounts varied from $212 for the American Psychiatric Association leaders to $518 000 for the American Society of Clinical Oncology. CONCLUSIONS:Financial relationships between the leaders of influential US professional medical associations and industry are extensive, although with variation among the associations. The quantum of payments raises questions about independence and integrity, adding weight to calls for policy reform.
Project description:ObjectiveHow best to involve patients in the development of clinical practice guideline (CPG) recommendations is not known. We sought to determine the feasibility and value of developing CPG recommendations based on a voting panel composed entirely of patients, with the ultimate goal of comparing the patients' recommendations to ones developed by a physician-dominated voting panel on the same clinical questions.MethodsTen patients with rheumatoid arthritis completed 8 hours of training on evidence-based medicine and guideline development. They constituted a voting panel and, with 2 American College of Rheumatology staff with expertise in CPG development and a physician facilitator, subsequently met at a face-to-face meeting to develop recommendations. They applied the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology to formulate recommendations on 18 questions for which there was evidence warranting moderate or high confidence.ResultsThe patient panel developed recommendations for 16 of the 18 questions; for the other 2, the panel thought there were insufficient data to support a recommendation. For 13 of the 16 questions, the patient panel recommended the same course of action as did the physician-dominated panel. Differences were due to how the 2 panels valued the balance between benefits and harms.ConclusionPatient and physician-dominated panels developed the same recommendations for most questions for which there was evidence warranting moderate to high confidence. Additional experiences are necessary to advance the evidence necessary to determine what panel composition is optimal to produce the best guidelines.
Project description:Importance:It is well documented that financial conflicts of interest influence medical research and clinical practice. Prior to the Open Payments provisions of the Affordable Care Act, financial ties became apparent only through self-disclosure. The nature of financial interests has not been studied among physicians who develop dermatology clinical practice guidelines. Objective:To evaluate payments received by physicians who author dermatology clinical practice guidelines, compare disclosure statements for accuracy, determine whether pharmaceutical companies from which the authors received payments manufactured products related to the guidelines, and examine the extent to which the American Academy of Dermatology enforced their Administrative Regulations for guideline development. Design, Setting, and Participants:Three American Academy of Dermatology guidelines published from 2013 to 2016 were retrieved. Double data extraction was used to record financial payments received by 49 guideline authors using the Open Payments database. Payments received by the authors from the date of the initial literature search to the date of publication were used to evaluate disclosure statement accuracy, detail the companies providing payments, and evaluate Administrative Regulations enforcement. This study is applicable to clinical practice guideline panels drafting recommendations, physicians using clinical practice guidelines to inform patient care, and those establishing policies for guideline development. Main Outcomes and Measures:Our main outcomes are the monetary values and types of payments received by physicians who author dermatology guidelines and the accuracy of disclosure statements. Data were collected from the Open Payments database and analyzed descriptively. Results:Of the 49 authors evaluated, 40 received at least 1 reported industry payment, 31 accepted more than $1000, 25 accepted more than $10?000, and 18 accepted more than $50?000. Financial payments amounted to a mean of $157?177 per author. The total reimbursement among the 49 authors from 2013 to 2015 was $7?701?681. Of the 40 authors receiving payments, 22 did not accurately disclose industry relationships. Authors received payments from companies with products directly related to the guideline topic. Violations to the Administrative Regulations were found. Conclusions and Relevance:Dermatology clinical practice guideline authors received sizable industry payments and did not completely disclose these payments. The American Academy of Dermatology policies may benefit from stricter enforcement or the adoption of new standards.
Project description:Trustworthy health guidelines should provide recommendations, document the development process, and highlight implementation information. Our objective was to develop a guideline manuscript template to help authors write a complete and useful report. The McMaster Grading of Recommendations Assessment, Development and Evaluation Centre collaborated with the American Society of Hematology (ASH) to develop guidelines for the management of venous thromboembolism. A template for reporting the guidelines was developed based on prior approaches and refined using input from other key stakeholders. The proposed guideline manuscript template includes: (1) title for guideline identification, (2) abstract, including a summary of key recommendations, (3) overview of all recommendations (executive summary), and (4) the main text, providing sufficient detail about the entire process, including objectives, background, and methodological decisions from panel selection and conflict-of-interest management to criteria for updating, as well as supporting information, such as links to online (interactive) tables. The template further allows for tailoring to the specific topic, using examples. Initial experience with the ASH guideline manuscript template was positive, and challenges included drafting descriptions of recommendations involving multiple management pathways, tailoring the template for a specific guideline, and choosing key recommendations to highlight. Feedback from a larger group of guideline authors and users will be needed to evaluate its usefulness and refine. The proposed guideline manuscript template is the first detailed template for transparent and complete reporting of guidelines. Consistent application of the template may simplify the preparation of an evidence-based guideline manuscript and facilitate its use.
Project description:Recently, the US Food and Drug Administration and European Medicines Agency have issued new guidance for industry on drug interaction studies, which outline comprehensive recommendations on a broad range of in vitro and in vivo studies to evaluate drug-drug interaction (DDI) potential. This paper aims to provide an overview of these new recommendations and an in-depth scientifically based perspective on issues surrounding some of the recommended approaches in emerging areas, particularly, transporters and complex DDIs. We present a number of theoretical considerations and several case examples to demonstrate complexities in applying (1) the proposed transporter decision trees and associated criteria for studying a broad spectrum of transporters to derive actionable information and (2) the recommended model-based approaches at an early stage of drug development to prospectively predict DDIs involving time-dependent inhibition and mixed inhibition/induction of drug metabolizing enzymes. We hope to convey the need for conducting DDI studies on a case-by-case basis using a holistic scientifically based interrogative approach and to communicate the need for additional research to fill in knowledge gaps in these areas where the science is rapidly evolving to better ensure the safety and efficacy of new therapeutic agents.
