From the Patient Perspective, Consent Forms Fall Short of Providing Information to Guide Decision Making

Role of procedure-specific consent forms in clinical practice: a systematic review

INTRODUCTION

Consent forms play an active role in the consent process with generic, handwritten consent forms (GCF) often the standard across the National Health Service. Increasingly, procedure-specific consent forms (PSCF) are being used as an alternative. However, concerns remain about whether they meet the standard for consent. We therefore conducted a systematic review with the objectives of investigating evidence for PSCF, study methodology and medicolegal criteria.

METHODS

This systematic review was prospectively registered on PROSPERO (CRD42023392693) and conducted from 1 January 1990 to 17 March 2023 using the MEDLINE, Embase, CINAHL, CENTRAL and Emcare databases. A grey literature search was also performed. All studies evaluating PSCF in medical and surgical settings were included. Risk-of-bias analysis was performed using 'RoB 2' and 'ROBINS-I'. Meta-analysis was not possible because of the results' heterogeneity.

FINDINGS

We identified 21 studies investigating PSCF with no systematic reviews and meta-analyses reported. Most studies were quality improvement projects (n = 10) followed by randomised studies (n = 5). No definitive legal guidance for PSCFs and no studies assessing their role in litigation post-procedural complications were identified. PSCFs were associated with improved documentation (70%-100%; n = 11) and legibility (100%; n = 2) compared with GCF. Randomised studies (n = 4) investigating patient understanding and recall for PSCF were inconclusive compared with GCF.

CONCLUSIONS

The heterogeneous evidence available merely demonstrates superior documentation of PSCF compared with GCF. Studies do not adequately investigate the impact on informed consent and fail to address the associated legal concerns. Further randomised studies with patient-centric outcomes and consideration for medicolegal criteria are needed.

Compromised informed consent due to functional health literacy challenges in Chinese hospitals

BACKGROUND

Medical informed consent stands as an ethical and legal requisite preceding any medical intervention. Hospitalized patients face functional health literacy (FHL) challenges when dealing with informed consent forms (ICFs). The legitimacy of ICFs and informed consent procedures in China remains substantially undisclosed. The study's aim was to investigate if Chinese patients have adequate FHL to be truly informed before providing medical consent.

METHODS

In this cross-sectional, structured interview-based study, FHL was assessed within the context of the informed consent scenarios in two teaching hospitals (a 1500-bed general tertiary hospital and a 700-bed cancer hospital) affiliated with Shantou University Medical College. Twenty-seven patients admitted across clinical departments, along with their relatives (n = 59), were enrolled in the study after obtaining informed consent. The participants underwent a three-step assessment with two selected ICFs -teach-back skills, perceived understanding (perception), and informed knowledge (cognizance), with each component carrying a maximum score of 10. Data were analyzed with SPSS (version 22.0) for descriptive and inferential statistics, with consideration of significant P values as < 0.05.

RESULTS

The median age (IQR and range) of participants was 35.5 (28 - 49 and 13 - 74) years. Most participants had only high school education (24.4%, 21/86) or below high school education (47.7%, 41/86). The median score (IQR) of FHL assessments-teach-back, perception, and cognizance-was 4.0 (2.5, 5.8), 8.0 (6.8, 8.8), and 6.5 (5.5, 8.0) out of 10, respectively. A moderate correlation was observed between the scores of cognizance and teach-back (r = 0.359, P = 0.002) or perception (r = 0.437, P < 0.001). Multivariate linear regression analysis predicted being a patient and having lower education levels as independent risk factors of inadequate FHL (Ps = 0.001). Lack of patient-centeredness in ICFs, time constraints, and poor clinical communication were identified as barriers impeding informed consent.

CONCLUSIONS

This study demonstrates inadequacy in personal FHL and impaired organizational HL, resulting in compromised informed consent in Chinese teaching hospitals. As a remedy, we propose improving the quality of ICFs and institutionally mandated outcome-focused training on informed consent for all concerned clinicians to enhance medical ethics, ensure quality health care, address patient values, and mitigate potential medical conflicts.

Clinical trial recruitment of people who speak languages other than English: a Children's Oncology Group report

BACKGROUND

Persons who speak languages other than English are underrepresented in clinical trials, likely in part because of inadequate multilevel resources. We conducted a survey of institutions affiliated with the Children's Oncology Group (COG) to characterize current research recruitment practices and resources regarding translation and interpretation services.

METHODS

In October 2022, a 20-item survey was distributed electronically to institutions affiliated with COG to assess consent practices and resources for recruiting participants who speak languages other than English to COG trials. Descriptive statistics were used to summarize responses; responses were compared by institution size and type as well as respondent role.

RESULTS

The survey was sent to 230 institutions, and the response rate was 60% (n = 139). In total, 60% (n = 83) of those respondents had access to short-form consent forms. Full consent form translation was required at 50% of institutions, and 12% of institutional review boards restricted use of centrally translated consent forms. Forty-six percent (n = 64) of institutions reported insufficient funding to support translation costs; 19% (n = 26) had access to no-cost translation services. Forty-four percent (n = 61) were required to use in-person interpreters for consent discussions; the most frequently cited barrier (56%) to obtaining consent was lack of available in-person interpreters. Forty-seven percent (n = 65) reported that recruiting persons who speak languages other than English to clinical trials was somewhat or very difficult.

CONCLUSIONS

Institutions affiliated with COG face resource-specific challenges that impede recruitment of participants who speak languages other than English for clinical trials. These findings indicate an urgent need to identify strategies aimed at reducing recruitment barriers to ensure equitable access to clinical trials.

Informed consent in clinical practice: Old problems, new challenges

Informed consent is a fundamental tenet of patient-centred clinical practice as it upholds the ethical principle of patient autonomy and promotes shared decision-making. In the medicolegal realm, failure to meet the accepted standards of consent can be considered as medical negligence which has both legal and professional implications. In general, valid consent requires three core components: (1) the presence of mental capacity - characterised by the patient's ability to comprehend, retain information, weigh options and communicate the decision, (2) adequate information disclosure - based on the 'reasonable physician' or 'reasonable patient' standards and (3) voluntariness in decision-making. Nonetheless, in real-world clinical settings, informed consent is not always optimally achieved, due to various patient, contextual and systemic factors. In this article, I herein discuss three major challenges to informed consent in clinical practice: (1) patient literacy and sociocultural factors, (2) psychiatric illnesses and elderly patients with cognitive impairment and (3) artificial intelligence in clinical care, and sought to offer practical mitigating strategies to address these barriers.

Creation of a risk of harms informed consent form for dry needling: A nominal group technique

BACKGROUND

When consenting patients to dry needling treatment, it is necessary to inform patients of potential risks of harms.

OBJECTIVES

The aim of this study was to identify elements and framework for an Informed Consent (IC) risk of harm statement to improve patient decision-making.

DESIGN

A virtual Nominal Group Technique (vNGT) methodology was used to achieve consensus among participants to identify what needs to be on a consent form, how it should be framed, and what it should state so patients understand the true risks.

METHODS

Eligible participants were identified as one of four groups: legal expert, policy expert, dry needling expert, or patient. The vNGT session consisted of 5 rounds of idea generation and final consensus voting which lasted for 2 h.

RESULTS

Five individuals consented to participate. Of the 27 original ideas, 22 reached consensus including ones specifically related to a risk of harms statement: identifying risks and discomforts, identify different sensations, and using a classification to order risks by severity. Consensus was achieved with percent agreement of ≥ 80%. The constructed risk of harm statement had a reading level of grade 7 and provided a list of stratified risks associated with dry needling.

CONCLUSION

The generated risk of harm statement can be incorporated on IC forms that require disclosure of risks in both the clinical and research setting. Additionally, further elements were identified by panel participants about defining the framework for an IC form outside of the risk of harm statement.

"How about me giving blood for the COVID vaccine and not being able to get vaccinated?" A cognitive interview study on understanding of and agreement with broad consent for future use of data and samples in Colombia and Nicaragua

Broad consent for future use, wherein researchers ask participants for permission to share participant-level data and samples collected within the study for purposes loosely related to the study objectives, is central to enabling ethical data and sample reuse. Ensuring that participants understand broad consent-related language is key to maintaining trust in the study and public health research. We conducted 52 cognitive interviews to explore cohort research participants' and their parents' understanding of the broad consent-related language in the University of California at Berkeley template informed consent (IC) form for biomedical research. Participants and their parents were recruited from long-standing infectious disease cohort studies in Nicaragua and Colombia and interviewed during the COVID-19 pandemic. We conducted semi-structured interviews to assess participants' agreement with the key concepts in the IC after clarifying them through the cognitive interview. Participants did not understand abstract concepts, including collecting and reusing genetic data. Participants wanted to learn about incidental findings, future users and uses. Trust in the research team and the belief that sharing could lead to new vaccines or treatments were critical to participant support for data and sample sharing. Participants highlighted the importance of data and sample sharing for COVID-19 response and equitable access to vaccines and treatments developed through sharing. Our findings on participants' understanding of broad consent and preferences for data and sample sharing can help inform researchers and ethics review committees working to enable ethical and equitable data and sample sharing.

Shared decision-making in the management of hereditary angioedema: An analysis of patient and physician perspectives

Background: Hereditary angioedema (HAE) is a rare genetic disorder characterized by recurrent, localized episodes of edema. Current treatment guidelines highlight the importance of shared decision-making (SDM) during implementation of HAE management plans. Objective: To determine what constitutes a successful SDM approach in HAE management. Method: Qualitative telephone interviews, which lasted ∼1 hour, were conducted with four HAE physicians and four patients from the APeX-S trial. The physicians were asked to describe the structure and/or content of typical HAE prophylaxis consultations and factors to consider when selecting medications for long-term treatment. Insights from these interviews were used to develop an SDM process diagram. The patients were interviewed to assess how closely the diagram fit their perspectives on the HAE consultation and their involvement in decisions that concerned their care. Interview transcripts were assessed by the interviewer to determine the degree of SDM involvement in each consultation by using qualitative criteria from the literature. Results: Two physicians followed a high-SDM format, and one physician used a "blended" approach. The fourth physician followed a standard (low SDM) format. A successful SDM approach was found to require pre-visit planning, a commitment on behalf of the physician to use SDM methods to learn more about the patient, and empowerment of the patient to reflect on and vocalize his or her preferences and/or needs. Patients engaged in SDM were more likely to proactively request a treatment switch. Conclusion: The adoption of validated HAE-specific treatment decision aids, as well as measures to change the mindsets of patients and physicians, may facilitate successful implementation of SDM in HAE.Clinical Trial Registration: The APeX-S trial was registered with clinicaltrials.gov (NCT03472040).

Collaboration and Shared Decision-Making Between Patients and Clinicians in Preventive Health Care Decisions and US Preventive Services Task Force Recommendations

The US Preventive Services Task Force (USPSTF) works to improve the health of people nationwide by making evidence-based recommendations for preventive services. Patient-centered care is a core value in US health care. Shared decision-making (SDM), in which patients and clinicians make health decisions together, ensures patients' rights to be informed and involved in preventive care decisions and that these decisions are patient-centered. SDM has a role across the spectrum of USPSTF recommendations. For A or B recommendations (judged by the USPSTF to have high or moderate certainty of a moderate or substantial net benefit at the population level), SDM allows individual patients to decide whether to accept such services based on their personal values and preferences. For C recommendations (indicating at least moderate certainty of a small net benefit at the population level), SDM is critical for individual patients to decide whether the net benefit for them is worthwhile. For D recommendations (reflecting at least moderate certainty of a zero or negative net benefit) or I statements (low certainty of net benefit), clinicians should be prepared to discuss these services if patients ask. More evidence is needed to determine if, in addition to promoting patient-centeredness, SDM reduces inequities in preventive care, as well as to define new strategies to find time for discussion of preventive services in primary care.

Utilizing the "teach-back" method to improve surgical informed consent and shared decision-making: a review

The teach-back method is a valuable communication tool that can be employed to improve patient safety and shared decision-making. Its utility in patient care has been studied extensively in many areas of clinical medicine. However, the literature on the use of teach-back in surgical patient education and informed consent is limited. Additionally, there is some ambiguity about the functional definition and performance of the teach-back method in the literature, consequently rendering this valuable tool an enigma. This review examines the current standards and ethics of preoperative informed consent and provides a concise, actionable definition of teach-back. The manner in which teach-back has been implemented in medicine and surgery is then examined in detail. Studies analyzing the use of teach-back in medicine have demonstrated its effectiveness and benefit to patient care. Further study on the use of teach-back to improve preoperative informed consent is supported by the few preliminary trials showing a positive effect after implementing the teach-back method in critical patient interactions.

Aligning Family-Clinician Expectations During Pediatric Surgical Informed Consent: Development and Implementation of an Innovative Communication Skills Workshop

INTRODUCTION

Aligning expectations during the informed consent process before a child's surgery is an important element of good communication that benefits both surgical staff and families. We developed and evaluated a 2-hour pilot interprofessional workshop to improve the communication and relational skills of pediatric surgeons and nurse practitioners.

METHODS

Focus groups with families identified key challenges in the process of informed consent. An interprofessional team, including parents whose children had experienced complex surgeries, developed the workshop collaboratively. A realistic simulation with professional actors portraying parents allowed surgical staff to practice communication skills and receive feedback about the parent perspective. Participants completed a postworkshop evaluation to determine whether the workshop met its objectives and whether they would change practice.

RESULTS

Five key themes identified for the workshop included customize communication; align expectations; share clinical uncertainty; recognize/attend to emotions; and identify team members. Thirty-five clinicians participated in a workshop, and 89% completed evaluations. Three-quarters reported the learning to be valuable, and 64% were likely to change practice. Eighty-seven percent would recommend the workshop to other colleagues, and 58 to 74% felt more prepared to achieve each of eight specific skills.

DISCUSSION

An innovative workshop for pediatric surgical practitioners to align family-clinician expectations can help improve clinician communication skills and comfort with informed consent. Keys to workshop development included involving parents to identify themes and participate as workshop co-faculty; enlisting leadership and recruiting surgical champions; and using pre-existing meetings to ease scheduling challenges of busy practitioners. Booster sessions may facilitate the desired cultural changes.

Rebooting consent in the digital age: a governance framework for health data exchange

In August 2020, India announced its vision for the National Digital Health Mission (NDHM), a federated national digital health exchange where digitised data generated by healthcare providers will be exported via application programme interfaces to the patient's electronic personal health record. The NDHM architecture is initially expected to be a claims platform for the national health insurance programme 'Ayushman Bharat' that serves 500 million people. Such large-scale digitisation and mobility of health data will have significant ramifications on care delivery, population health planning, as well as on the rights and privacy of individuals. Traditional mechanisms that seek to protect individual autonomy through patient consent will be inadequate in a digitised ecosystem where processed data can travel near instantaneously across various nodes in the system and be combined, aggregated, or even re-identified.In this paper we explore the limitations of 'informed' consent that is sought either when data are collected or when they are ported across the system. We examine the merits and limitations of proposed alternatives like the fiduciary framework that imposes accountability on those that use the data; privacy by design principles that rely on technological safeguards against abuse; or regulations. Our recommendations combine complementary approaches in light of the evolving jurisprudence in India and provide a generalisable framework for health data exchange that balances individual rights with advances in data science.

Personalized video consent in Blepharoplasty: A new paradigm in the preoperative consent giving process

BACKGROUND

Informed consent is not simply the signing of a form by the patient but more significantly, a process of an in-depth communication between the doctor and the patient.

AIM

The written informed consent process typically involves reading a lengthy document involving the medical terms which at times lead to misinterpretation. Therefore, the current research envisages assessing the effectiveness and acceptability of the video consent tool athwart the traditional written consent procedure.

METHODS

A retrospective questionnaire study was carried out with 30 patients posted for Blepharoplasty surgery between ages of 18-50 years. They were divided into two groups randomly. All the participants were given written consent. Video consent was taken additionally for group 2 subjects. All the participants received pre-validated questionnaire. The evaluation scale used was a 5-point Likert scale.

RESULTS

People with video consent group were more satisfied with the consent process. It was noted that all the patients who received video consent were happier and understood the consent process better than patients with written consent only.

CONCLUSION

The inference drawn from our study depicts that video consent is not just easy to understand and clarifies the doubts associated with the surgery but also significantly reduces the anxiety of the patient preoperatively. Also, in other 'quality of life' improving cosmetic procedures including rhinoplasty, face lift surgeries, jaw surgeries, botox, fillers, lasers etc., video consenting tool can be used to a maximum benefit. It is strongly recommended to adopt the practice of taking video consent format in all forms of cosmetic procedures.

Decision-making for older patients undergoing emergency laparotomy: defining patient and clinician values and priorities

AIM

There remains limited knowledge on what patients value and prioritize in their decision to undergo emergency laparotomy (ELap) and during their subsequent recovery. The aim of this study was to explore factors in decision-making and to reach a consensus amongst patients on the 10 most important priorities in decision-making in ELap.

METHODS

Patients aged over 65 years who had required an ELap decision within the preceding 12 months (regardless of management) were identified and invited to attend a modified Delphi process focus group.

RESULTS

A total of 20 participants attended: eight patients, four relatives and eight perioperative specialists. The perioperative specialists group defined 12 important factors for perioperative decision-making. The patient group agreed that only six (50%) of these factors were important: independence, postoperative complications, readmission to hospital, requirement for stoma formation, delirium (including long-term cognition) and presence of an advocate (such as a friend or family member). Open discussion refined multiple themes. Agreement was reached by patients and relatives about 10 factors that they valued as most important in their ELap patient journey: return to independence, realistic expectations, postoperative complications, what to expect postoperatively, readmission to hospital, nutrition, postoperative communication, stoma, follow-up and delirium.

CONCLUSION

Patients and clinicians have different values and priorities when discussing the risks and implications of undergoing ELap. Patients value quality of life outcomes, in particular, the formation of a stoma, returning to their own home and remaining independent. This work is the first to combine both perspectives to guide future ELap research outcomes.

Optimised patient information materials and recruitment to a study of behavioural activation in older adults: an embedded study within a trial

Background: Printed participant information about randomised controlled trials is often long, technical and difficult to navigate. Improving information materials is possible through optimisation and user-testing, and may impact on participant understanding and rates of recruitment. Methods: A study within a trial (SWAT) was undertaken within the CASPER trial. Potential CASPER participants were randomised to receive either the standard trial information or revised information that had been optimised through information design and user testing. Results: A total of 11,531 patients were randomised in the SWAT. Rates of recruitment to the CASPER trial were 2.0% in the optimised information group and 1.9% in the standard information group (odds ratio 1.027; 95% CI 0.79 to 1.33; p=0.202). Conclusions: Participant information that had been optimised through information design and user testing did not result in any change to rate of recruitment to the host trial. Registration: ISRCTN ID ISRCTN02202951; registered on 3 June 2009.

Shortened consent forms for genome-wide sequencing: Parent and provider perspectives

BACKGROUND

Consent forms for exome and/or genome sequencing, collectively called genome-wide sequencing (GWS), frequently contain detailed information on complex topics such as sequencing analysis and incidental findings. Considering recent endeavors by the health care community to simplify GWS consent forms, it is important to gain stakeholders' perspectives on the content, length, and use of consent forms.

METHODS

Thematic analysis was conducted on data obtained from focus groups with two participant cohorts: parents who previously provided consent for trio-based GWS as part of the translational pediatric GWS CAUSES Study, and genetic health care providers (HCP) who provide pre-test counseling for GWS.

RESULTS

Genetic HCP indicated that consent forms cannot replace pre-test counseling, and as such, a simplified consent form focusing on the implications of GWS would be beneficial to both patients and HCP. Although parents' primary concerns varied when considering GWS, they all highly valued information. Parents also indicated the need for community and support after the return of GWS results. Both participant cohorts recommended that consent forms be available online and include an appendix for supplementary information.

CONCLUSION

It is important to include both parents and HCP in the design of GWS consent forms, and also, to help connect families who have a shared diagnosis after the post-test counseling session.

Improving quality of the informed consent process: Developing an easy-to-read, multimodal, patient-centered format in a real-world setting

OBJECTIVE

To develop a patient-centered informed consent and assessment tool written at a 6th grade-level that is multimodal, affordable, transportable, and readily modifiable for protocol updates.

METHODS

This quality improvement initiative was performed in two phases on an actively-recruiting study at a pediatric diabetes clinic. In phase I, 38 volunteers underwent the standard-paper consent process, a comprehension assessment and provided feedback. Using feedback and the structure of the Plan-Do-Study-Act cycle a multimodal consent and assessment were developed. In phase II, volunteers were randomized to the standard (n = 25) or the multimodal consent (n = 25) and all completed the same comprehension assessment via touch-screen tablet. Primary outcomes were comparison of the individual and total comprehension assessment scores.

RESULTS

Total comprehension scores were higher in the multimodal versus the standard consent group (p <  0.001) and on the elements of benefits (p <  0.001), risks (p <  0.001), volunteerism (p <  0.012), results (p <  0.001), confidentiality (p <  0.004) and privacy (p < 0.001).

CONCLUSION

A multimodal consent and assessment presented sequentially on a touch-screen tablet were patient-centered enhancements to standard consent.

PRACTICE IMPLICATIONS

Multimodal standardization of delivery with improved readability may strengthen the informed consent process.

The Future of Clinical Trial Design: The Transition from Hard Endpoints to Value-Based Endpoints

Clinical trials have been conducted since 500 BC. Currently, the methodological gold standard is the randomized controlled clinical trial, introduced by Austin Bradford Hill. This standard has produced enormous amounts of high-quality evidence, resulting in evidence-based clinical guidelines for physicians. However, the current trial paradigm needs to evolve because of the ongoing decrease of the incidence of hard endpoints and spiraling trial costs. While new trial designs, such as adaptive clinical trials, may lead to an increase in efficiency and decrease in costs, we propose a shift towards value-based trial design: a paradigm that mirrors value-based thinking in business and health care. Value-based clinical trials will use technology to focus more on symptoms and endpoints that patients care about, will incorporate fewer research centers, and will measure a state or consequence of disease at home or at work. Furthermore, they will measure the subjective experience of subjects in relation to other objective measurements. Ideally, the endpoints are suitable for individual assessment of the effect of an intervention. The value-based clinical trial of the future will have a low burden for participants, allowing for the inclusion of neglected populations such as children and the elderly, will be data-rich due to a high frequency of measurements, and can be conducted with technology that is already available.

Improving readability of informed consents for research at an academic medical institution

Introduction

The final rule for the protection of human subjects requires that informed consent be “in language understandable to the subject” and mandates that “the informed consent must be organized in such a way that facilitates comprehension.” This study assessed the readability of Institutional Review Board-approved informed consent forms at our institution, implemented an intervention to improve the readability of consent forms, and measured the first year impact of the intervention.

Methods

Readability assessment was conducted on a sample of 217 Institutional Review Board-approved informed consents from 2013 to 2015. A plain language informed consent template was developed and implemented and readability was assessed again after 1 year.

Results

The mean readability of the baseline sample was 10th grade. The mean readability of the post-intervention sample (n=82) was seventh grade.

Conclusions

Providing investigators with a plain language informed consent template and training can promote improved readability of informed consents for research.

Views of clinical trial participants on the readability and their understanding of informed consent documents

BACKGROUND

One of the ethical imperatives for a valid consent process in clinical medication trials is that the process be guided by and recorded in an informed consent document (ICD). Concerns have been expressed, however, about readability and participant understanding of ICDs, which are often 10-20 pages long. Objective measures of readability and understanding have been used to support these concerns in several articles, but surprisingly the voice of trial participants on ICDs has not been heard in previous studies. Hence, this study compares participants' subjective views on readability and their understanding of ICDs with those ICDs' objective readability scores. It also evaluates whether family, friends, and additional aids would foster better understanding of the ICD.

METHODS

Sixty current trial participants rated the readability and their understanding of deidentified standard ICDs. These had been sourced from two multicenter international Phase III trials on medication for diabetes mellitus and cancer.

RESULTS

Less than 10% of participants considered the ICDs difficult to read or difficult to understand in spite of objective readability scores at levels of about 12th grade education, but about a quarter considered the ICDs to be too technical. Participants gave mixed responses about friends or family members helping or the need for videos, pictures, additional reading material, and frequently answered questions (FAQ) sheets as an aid to their understanding.

CONCLUSIONS

These findings suggest individual clinical trial participants should be engaged on their views of an ICD, for doing so is part of informed consent as a process rather than consent being merely focused on written information. Such participant-specific engagement should guide whether family and friends, videos, pictures, additional reading material, and FAQ sheets would be of assistance in improving understanding.

Improving the Informed Consent Process in Hematopoietic Cell Transplantation: Patient, Caregiver, and Provider Perspectives

One of the significant modifications to the Common Rule is the requirement that prospective participants be given information sufficient for a "reasonable person." However, research is limited on what types of information patients, caregivers, and providers consider "key information." Although certain aspects of informed consent (IC) may be considered standard, considering the individualized needs and preferences of patients is necessary for patient-centered consent. In this study, we qualitatively examined the specific types of information that patients and caregivers involved in hematopoietic cell transplantation (HCT), as well as their providers, believe to be important and necessary as part of the IC process to make a decision about participating in clinical research; and further, how these perspectives are aligned. Our findings suggest opportunities for improving the IC document and process by emphasizing information of importance to patients, such as the benefits to others and contributions to science that are associated with participation in clinical research. Furthermore, increasing patient engagement during the IC process may allow providers to streamline information that is aligned with patient information needs and preferences.

The Appropriateness of Language Found in Research Consent Form Templates: A Computational Linguistic Analysis

Background

To facilitate informed consent, consent forms should use language below the grade eight level. Research Ethics Boards (REBs) provide consent form templates to facilitate this goal. Templates with inappropriate language could promote consent forms that participants find difficult to understand. However, a linguistic analysis of templates is lacking.

Methods

We reviewed the websites of 124 REBs for their templates. These included English language medical school REBs in Australia/New Zealand (n = 23), Canada (n = 14), South Africa (n = 8), the United Kingdom (n = 34), and a geographically-stratified sample from the United States (n = 45). Template language was analyzed using Coh-Metrix linguistic software (v.3.0, Memphis, USA). We evaluated the proportion of REBs with five key linguistic outcomes at or below grade eight. Additionally, we compared quantitative readability to the REBs’ own readability standards. To determine if the template’s country of origin or the presence of a local REB readability standard influenced the linguistic variables, we used a MANOVA model.

Results

Of the REBs who provided templates, 0/94 (0%, 95% CI = 0–3.9%) provided templates with all linguistic variables at or below the grade eight level. Relaxing the standard to a grade 12 level did not increase this proportion. Further, only 2/22 (9.1%, 95% CI = 2.5–27.8) REBs met their own readability standard. The country of origin (DF = 20, 177.5, F = 1.97, p = 0.01), but not the presence of an REB-specific standard (DF = 5, 84, F = 0.73, p = 0.60), influenced the linguistic variables.

Conclusions

Inappropriate language in templates is an international problem. Templates use words that are long, abstract, and unfamiliar. This could undermine the validity of participant informed consent. REBs should set a policy of screening templates with linguistic software.
