Project description:IntroductionRecent revisions to the US Federal Common Rule governing human studies funded or conducted by the federal government require the provision of a "concise and focused" key information (KI) section in informed consent forms (ICFs). We performed a systematic study to characterize KI sections of ICFs for federally funded trials available on ClinicalTrials.gov.MethodsWe downloaded ICFs posted on ClinicalTrials.gov for treatment trials initiated on or after the revised Common Rule effective date. Trial records (n = 102) were assessed by intervention type, study phase, recruitment status, and enrollment size. The ICFs and their KI sections, if present, were characterized by page length, word count, readability, topic, and formatting elements.ResultsOf the 102 trial records, 76 had identifiable KI sections that were, on average, 10% of the total length of full ICF documents. KI readability grade level was not notably different from other sections of ICFs. Most KI sections were distinguished by section headers and included lists but contained few other formatting elements. Most KI sections included a subset of topics consistent with the basic elements of informed consent specified in the Common Rule.ConclusionMany of the KI sections in the study sample aligned with practices suggested in the preamble to the revised Common Rule. Further, our results suggest that some KI sections were tailored in study-specific ways. Nevertheless, guidelines on how to write concise and comprehensible KI sections would improve the utility and readability of KI sections.

Project description:Long informed consent forms (ICFs) remain commonplace, yet they can negatively affect potential participants' understanding of clinical research. We aimed to build consensus among six groups of key stakeholders on advancing the use of shorter ICFs in clinical research. Partnering with the HIV Prevention Trials Network (HPTN), we used a modified Delphi process with semistructured interviews and online surveys. Concerns about redundancy of information were common. Respondents supported three strategies for reducing ICF length: (a) 91% agreed or strongly agreed with grouping study procedures by frequency, (b) 91% were comfortable or very comfortable with placing supplemental information into appendices, and (c) 93% agreed or strongly agreed with listing duplicate side effects only once. Implementing these strategies will facilitate adoption of the proposed changes to U.S. regulations on ICF length, should they be enacted.

Project description:Informed consent is essential to ethical research and is requisite to participation in clinical research. Yet most hematopoietic cell transplantation (HCT) informed consent forms (ICFs) are written at reading levels that are above the ability of the average person in the United States (U.S.). The recent development of ICF templates by the National Cancer Institute, National Institutes of Health, and the National Heart Blood and Lung Institute have not resulted in increased patient comprehension of information. Barriers to creating Easy-to-Read ICFs that meet U.S. federal requirements and pass institutional review board (IRB) review are the result of multiple interconnected factors. The Blood and Marrow Transplant Clinical Trials Network (BMT CTN) formed an ad hoc review team to address concerns regarding the overall readability and length of ICFs used for BMT CTN trials. This paper summarizes recommendations of the review team for the development and formatting of Easy-to-Read ICFs for HCT multicenter clinical trials, the most novel of which is the use of a 2-column format. These recommendations intend to guide the ICF writing process, simplify local IRB review of the ICF, enhance patient comprehension, and improve patient satisfaction. The BMT CTN plans to evaluate the impact of the Easy-to-Read format compared with the traditional format on the informed consent process.

Project description:IntroductionThe purpose of the informed consent form (ICF) is to outline the risks and benefits of an interventional clinical trial to potential participants. The aim of this study was to explore the feasibility of a short addendum to the ICF, summarizing key points most relevant to potential participants.MethodsA sample of 20 ICFs was reviewed against the requirements of the U.S. federal regulation documents and assessed for readability. Alongside the ICF review, we conducted focus groups and one-on-one interviews with people with lung cancer (n = 9) to learn what information was most important when considering participation in a clinical trial using a hypothetical phase 3 ICF.ResultsThe 20 ICFs reviewed were from phases 1 to 3, expanded-access, and single-patient trials covering predominantly NSCLC; 60% were global. The mean length of the ICFs was 21 (range: 15-34) pages. The average reading level was tenth grade whereas the average U.S. reading level was eighth grade. Readability varied by section, the "purpose of the study" section had the highest reading level. In the qualitative research component, participants were "overwhelmed" by the hypothetical ICF. Participants were also asked to list information for the addendum; their suggestions broadly map to federal regulations. An addendum with reference to sections in the ICF for additional details was well received.ConclusionsThe variations in ICF architecture and readability make it difficult for patients to make an informed decision to participate in a clinical trial. Implications extend beyond lung cancer, highlighting key areas for ICF improvements and providing a roadmap for developing a patient-centric addendum.

Project description:The recent research and technology development in medical genomics has raised new issues that are profoundly different from those encountered in traditional clinical research for which informed consent was developed. Global initiatives for international collaboration and public participation in genomics research now face an increasing demand for new forms of informed consent which reflect local contexts. This article analyzes informed consent forms (ICFs) for genomic research formulated by four selected research programs and institutes in East Asia - the Medical Genome Science Program in Japan, Universiti Sains Malaysia Human Research Ethics Committee in Malaysia, and the Taiwan Biobank and the Taipei Medical University- Joint Institutional Review Board in Taiwan. The comparative text analysis highlights East Asian contexts as distinct from other regions by identifying communicative and social functions of consent forms. The communicative functions include re-contact options and offering interactive support for research participants, and setting opportunities for family or community engagement in the consent process. This implies that informed consent cannot be validated solely with the completion of a consent form at the initial stage of the research, and informed consent templates can facilitate interactions between researchers and participants through (even before and after) the research process. The social functions consist of informing participants of possible social risks that include genetic discrimination, sample and data sharing, and highlighting the role of ethics committees. Although international ethics harmonization and the subsequent coordination of consent forms may be necessary to maintain the quality and consistency of consent process for data-intensive international research, it is also worth paying more attention to the local values and different settings that exist where research participants are situated for research in medical genomics. More than simply tools to gain consent from research participants, ICFs function rather as a device of social communication between research communities and civic communities in liaison with intermediary agents like ethics committees, genetic counselors, and public biobanks and databases.

Project description:The sociomedical environment is changing. In the traditional physician-patient relationship, the physician was authoritative and the patient was obedient. The contractual relationship featured patient consent to the physician's decision. Today, the physician must explain fully the planned medical treatment, and any alternative, to the patient, who has the right to choose her treatment after considering the benefits and side-effects. The Korean Society of Gynecologic Oncology (KSGO) thus decided to standardize the surgical consent forms to meet the legal requirements of modern medicine, improve patient understanding of the surgical details, and protect medical staff from legal disputes. To determine the format and content, subcommittees for each cancer type collected and reviewed all relevant articles and the current consent forms of domestic medical institutions. After several meetings, 16 basic items to be included for each type of gynecologic cancer were selected. Also, to help patients understand the surgical details, figures were included. The revised forms were legally reviewed in terms of the appropriateness of the format and content. We also developed English versions to provide adequate information for foreign patients. We hope that these efforts will promote trust between patients and physicians, and contribute to effective treatment by laying a foundation of mutual respect.

Project description:BackgroundAlthough patient advocates have developed templates for standard consent forms, evaluating patient preferences for first in human (FIH) and window of opportunity (Window) trial consent forms is critical due to their unique risks. FIH trials are the initial use of a novel compound in study participants. In contrast, Window trials give an investigational agent over a fixed duration to treatment naïve patients in the time between diagnosis and standard of care (SOC) surgery. Our goal was to determine the patient-preferred presentation of important information in consent forms for these trials.MethodsThe study consisted of two phases: (1) analyses of oncology FIH and Window consents; (2) interviews of trial participants. FIH consent forms were analyzed for the location(s) of information stating that the study drug has not been tested in humans (FIH information); Window consents were analyzed for the location(s) of information stating the trial may delay SOC surgery (delay information). Participants were asked about their preferred placement of the information in their own trial's consent form. The location of information in the consent forms was compared to the participants' suggestions for placement.Results34 [17 FIH; 17 Window] of 42(81%) cancer patients approached participated. 25 consents [20 FIH; 5 Window] were analyzed. 19/20 FIH consent forms included FIH information, and 4/5 Window consent forms included delay information. 19/20(95%) FIH consent forms contained FIH information in the risks section 12/17(71%) patients preferred the same. Fourteen (82%) patients wanted FIH information in the purpose, but only 5(25%) consents mentioned it there. 9/17(53%) Window patients preferred delay information to be located early in the consent, before the "Risks" section. 3/5(60%) consents did this.ConclusionsDesigning consents that reflect patient preferences more accurately is essential for ethical informed consent; however, a one-size fits all approach will not accurately capture patient preferences. We found that preferences differed for FIH and Window trial consents, though for both, patients preferred key risk information early in the consent. Next steps include determining if FIH and Window consent templates improve understanding.

Project description:BackgroundThe US Food and Drug Administration Amendments Act requires results from clinical trials of Food and Drug Administration-approved drugs to be posted at ClinicalTrials.gov within 1 y after trial completion. We compared the timing and completeness of results of drug trials posted at ClinicalTrials.gov and published in journals.Methods and findingsWe searched ClinicalTrials.gov on March 27, 2012, for randomized controlled trials of drugs with posted results. For a random sample of these trials, we searched PubMed for corresponding publications. Data were extracted independently from ClinicalTrials.gov and from the published articles for trials with results both posted and published. We assessed the time to first public posting or publishing of results and compared the completeness of results posted at ClinicalTrials.gov versus published in journal articles. Completeness was defined as the reporting of all key elements, according to three experts, for the flow of participants, efficacy results, adverse events, and serious adverse events (e.g., for adverse events, reporting of the number of adverse events per arm, without restriction to statistically significant differences between arms for all randomized patients or for those who received at least one treatment dose). From the 600 trials with results posted at ClinicalTrials.gov, we randomly sampled 50% (n?=?297) had no corresponding published article. For trials with both posted and published results (n?=?202), the median time between primary completion date and first results publicly posted was 19 mo (first quartile?=?14, third quartile?=?30 mo), and the median time between primary completion date and journal publication was 21 mo (first quartile?=?14, third quartile?=?28 mo). Reporting was significantly more complete at ClinicalTrials.gov than in the published article for the flow of participants (64% versus 48% of trials, p<0.001), efficacy results (79% versus 69%, p?=?0.02), adverse events (73% versus 45%, p<0.001), and serious adverse events (99% versus 63%, p<0.001). The main study limitation was that we considered only the publication describing the results for the primary outcomes.ConclusionsOur results highlight the need to search ClinicalTrials.gov for both unpublished and published trials. Trial results, especially serious adverse events, are more completely reported at ClinicalTrials.gov than in the published article.
