Assessment of Use, Specificity, and Readability of Written Clinical Informed Consent Forms for Patients With Cancer Undergoing Radiotherapy

Valid consent in the acute hospital setting: perspectives of patients and members of the public

BACKGROUND

People who interact with healthcare services have an ethical and legal right to control their own lives, to make informed decisions, and to consent to what happens to them. For consent to be considered ethically and legally valid, three key criteria must be met: consent must be given voluntarily; people must be sufficiently informed of all options; and people should have capacity to make the decision to give or withhold their consent.

AIM

This study set out to explore, through the use of surveys, the perspectives of patients and public in relation to consent.

METHOD

Surveys were developed for patients and the public and administered paper based (patients) and through social media (public).

RESULTS

One hundred and forty surveys were posted to patients, with a 38% response rate; 104 responses were received from the public. Ninety-six percent of patients were satisfied that the decision they made was informed; 100% felt they had made a voluntary decision; 98% felt the clinician seemed knowledgeable about the procedure. What matters most to the public were being informed about the risks associated with the proposed procedure and being assured that whatever choice they make they will receive the best care possible.

CONCLUSIONS

The results highlight interesting similarities and differences in relation to consent between members of the public thinking about a possible treatment, surgery, or procedure and those patients who have actually been through the process in the past 12 months. Recommendations have been developed on the basis of these findings to co-design improvements in consent practices.

Simulated anesthesia consent discussions demonstrate high level of comprehension and education requirements for patients: A pilot study

Objective

Patient comprehension of informed consent and demonstration of procedural understanding is often lacking in anesthesiology. The purpose of this study was to determine if patient communication in anesthesiology is being conducted effectively, and in a manner that ensures adequate communication between anesthesia professionals and their patients regarding procedures with associated risks and benefits.

Methods

Anesthesia professionals were recorded in a simulated setting explaining anesthesia procedures of increasing complexity with one control scenario. Score means were calculated, and statistical comparisons made between discussion of anesthesia procedures and the control scenario.

Results

Calculation of means for 6 readability tests demonstrated the grade level required to understand the medical practitioners' verbal communication was high and increased with complexity of the anesthesia procedure described. The control scenario required a statistically significant lower level of comprehension for the recipient of the information.

Conclusion

In simulated settings, anesthesia professionals regularly communicate procedural details in a manner that is difficult for the general public to understand. Subjects could communicate in simple terms when discussing a control.

Innovation

This pilot study demonstrated effective methodology, using artificial intelligence technology for transcription, to assess patient comprehension of verbal communication.

Assessment of online patient education material for eye cancers: A cross-sectional study

The objective of this study was to assess online American patient education material (PEM) related to eye cancers in order to determine the quality of the content and appropriateness of the contents' reading level as it relates to the American population. PEMs were extracted from fifteen American cancer and ophthalmology associations and evaluated for their reading level using ten validated readability scales. PEMs then had all words extracted and evaluated for their difficulty and familiarity. The quality of the PEMS were assessed according to DISCERN, Heath On the Net Foundation Code of Conduct (HONCode), and JAMA benchmarks. Overall, online PEMs from the associations were written at a 11th grade reading level, which is above the recommended 6th grade reading level. The difficult word analysis identified that 26% of words were unfamiliar. Only one of the fifteen association held a HONCode certification while no organization met the standards of all four JAMA benchmarks. The average score for DISCERN was 2.4 out of a total of 5 for the fifteen questions related to treatment option information quality. Consideration should be made to create PEMs at an appropriate grade reading level to encourage health literacy and ultimately promote health outcomes. Associations should also focus on incorporating easily identifiable quality indicators to allow patients to better identify reputable resources.

A cross-sectional audit of informed consent of online survey: Characteristics and adherence to prevalent guidelines

Background

Research on human participants requires formal approval from a competent ethics committee. During the recruitment of the research participants, obtaining informed consent is a prerequisite. The online survey method is used by many researchers as it can collect the data from a diverse population in a short time.

Aim

This study aimed to observe the characteristics and adherence to prevalent guidelines (set by the Indian Council of Medical Research [ICMR]) of informed consent coupled with online surveys.

Methods

We collected the informed consent text from online survey links obtained from a network of colleagues who got a request to participate in a survey. Data were collected from July 2020 to June 2022. The text was anonymized for further analysis. The word count, sentences, and Flesch reading ease score were calculated. The adherence to ICMR guidelines where checked by two authors individually and a consensus was reached to prepare the final result.

Results

A total of 44 online surveys in English were audited and among them, 10 did not have informed consent. The informed consent in 34 surveys had a median of 6 sentences and 84 words. The median reading ease score was 45.7 (college level). The majority of the consent states the purpose of the research (91.18%), the voluntary nature of the participation (85.29%), and mentioned that it is research (64.71%). However, the rest of the components are ignored by the majority of the survey consent form.

Conclusion

Informed consent form with online surveys lacks adherence to the components suggested by ICMR. Hence, the forms should be made carefully by the researchers so that the vigor of informed consent is maintained in the online surveys.

Validation testing of a language translation device for suitability in assisting Australian radiation therapists to communicate with Mandarin-speaking patients

Introduction

Clear, timely communication between practitioners and patients is key in ensuring equitable access to health services and optimal care. Australia's linguistically diverse population adds complexity to healthcare provision. This paper describes a validation study to assess clinical suitability of a language translation device, intended for use with Mandarin speaking patients undergoing radiotherapy (RT).

Materials and methods

After a comprehensive device selection process, common phrases used in RT practice were curated within one clinical center and translated by interpreters. Phrases were categorized by conversation type and readability (according to Flesch-Kincaid and FORCAST scores). Validation of device performance was undertaken by purposely selected radiation therapists (RTTs) who tested and evaluated the device using a survey with 5-point Likert scale responses. Statistical analysis was undertaken on Excel using Pearson's chi-square, z-test, interrater reliability/agreement and linear regression analyses.

Results

Six RTTs and two interpreters volunteered to participate in this study. 188 common phrases were spoken verbatim into the device and scored on a 5-point Likert scale, yielding an overall output accuracy of 66%. A z-test confirmed significance against prior comparative research and Linear regression analysis observed improved output between consecutive participants. 62.7% of interpreter scores were identical; a further 29.1% constituted a single point scoring variation. Poorer outcomes were observed with colloquial English and lower readability.

Conclusions

This study found the device produced suitable translation accuracy and identified language styles that should be avoided with use. Further research could consider clinical application, expanded languages and/or health disciplines, and development of a national RTT phrase list.

Increasing Diversity of Patients in Radiation Oncology Clinical Trials

Radiation oncology clinical trials lack full representation of the ethnic and racial diversity present in the general United States and in the cancer patient population. There are low rates of both recruitment and enrollment of individuals from underrepresented ethnic and racial backgrounds, especially Black and Hispanic patients, people with disabilities, and patients from underrepresented sexual and gender groups. Even if approached for enrollment, barriers such as mistrust in medical research stemming from historical abuse and contemporary biased systems, low socioeconomic status, and lack of awareness prohibit historically marginalized populations from participating in clinical trials. In this review, we reflect on these specific barriers and detail approaches to increase diversity of the patient population in radiation oncology clinical trials to better reflect the communities we serve. We hope that implementation of these approaches will increase the diversity of clinical trials patient populations in not only radiation oncology but also other medical specialties.

Communicating the Gynecologic Brachytherapy Experience (CoGBE): Clinician perceived benefits of a graphic narrative discussion guide

PURPOSE

Many current radiotherapy patient education materials are not patient-centered. An interprofessional team developed Communicating the Gynecologic Brachytherapy Experience (CoGBE), a graphic narrative discussion guide for cylinder, intracavitary, and interstitial high-dose-rate (HDR) gynecologic brachytherapy. This study assesses perceived clinical benefits, usability, and anxiety-reduction of CoGBE.

METHODS AND MATERIALS

An electronic survey was sent to members of the American Brachytherapy Society. Participants were assigned to assess one of the three modality-specific CoGBE versions using a modified Systems Usability Scale (SUS), modified state-trait anxiety index (mSTAI), and Likert-type questions. Free response data was analyzed using modified grounded theory.

RESULTS

Median modified SUS score was 76.3 (interquartile range [IQR], 71.3-82.5) and there were no significant differences between guide types. Median mSTAI was 40 (IQR, 40-43.3) for all guides collectively. The cylinder guide had a significantly higher median mSTAI than the intracavitary and interstitial guides (41.6 vs. 40.0 and 40.0; p = 0.04) suggesting the cylinder guide may have less impact on reducing anxiety. Most respondents reported that CoGBE was helpful (72%), would improve patient understanding (77%) and consultation memorability (82%), and was at least moderately likely to be incorporated into their practice (80%). Qualitative analysis themes included personalization and relatability (positive); generalizability (negative); illustrations (both).

CONCLUSIONS

Clinicians rate CoGBE as usable with potential to reduce patient anxiety, especially with more invasive treatment modalities including intracavitary or interstitial high-dose-rate. CoGBE has the potential to improve patient-clinician communication for a wider range of patients due to its accessible, adaptable, and patient-centered design.

Investigation of the Readability and Reliability of Online Health Information for Cancer Patients During the Coronavirus Pandemic

For cancer patients undergoing treatment who may be at higher risk of COVID-19, access to high-quality online health information (OHI) may be of particular importance amidst a plethora of harmful medical misinformation online. Therefore, we assessed the readability and quality of OHI available for various cancer types and treatment modalities. Search phrases included "cancer radiation COVID," "cancer surgery COVID," "cancer chemotherapy COVID," and "cancer type COVID," for the fourteen most common cancer types (e.g., "prostate cancer COVID" and "breast cancer COVID"), yielding a total of 17 search phrases. The first 20 sources were recorded and analyzed for each keyword, yielding a total of 340 unique sources. For each of these sources, the approximate grade level required to comprehend the text was calculated as a mean of five validated readability scores; subsequently, for the first ten results of each search, the DISCERN tool was manually used to assess quality. Search terms were translated into Spanish and French, and a quality assessment using the Health on the Net Code (HONcode) accreditation was conducted. The median grade level readability for all sources was 13 (IQR 11-14). Median DISCERN scores for the 170 sources assessed were 55 out of 75, suggesting good quality. OHI with quality scores below the median DISCERN score had a median readability of 12.5 (IQR 11-14) grade reading level vs 14 (IQR 12-17) for those above the median DISCERN score (T-test P < 0.0001). Percentages of HONcode-accredited websites were 34.9%, 39.9%, and 38.6% for English, Spanish, and French OHI, respectively. We conclude that efforts are needed to make high-quality OHI available at the appropriate reading level for patients with cancer; such efforts may contribute to the alleviation of disparities in access to healthcare information.

Assessing the Functional Accessibility, Actionability, and Quality of Patient Education Materials from Canadian Cancer Agencies

Patient education materials (PEM)s were extracted from provincial cancer agencies to determine their organizational health literacy by evaluating the quality, actionability, and functional accessibility (e.g., readability and understandability) of their PEMs. PEMs from 10 provincial agencies were assessed for their grade reading level (GRL), using eight numerical and two graphical readability scales, and underwent a difficult word analysis. The agencies were assessed for PEM quality using two methods (JAMA benchmarks and DISCERN), while actionability and understandability were assessed using the Patient Education Materials Assessment Tool (PEMAT). Seven hundred and eighty-six PEMs were analyzed. The overall average GRL was 9.3 ± 2.1, which is above the recommended 7th GRL for health information. The difficult word analysis showed that 15.4% ± 5.1% of texts contained complex words, 35.8% ± 6.8% of texts contained long words, and 24.2% ± 6.6% of texts contained unfamiliar words. Additionally, there was high overlap between the most frequently identified difficult words in the PEMs and the most frequently misunderstood words by cancer patients identified in the literature. Regarding quality indicators, no agency displayed all four indicators according to the JAMA benchmarks and DISCERN scores ranged between 38 (poor) to 66 (excellent). PEMAT scores ranged between 68% to 88% for understandability and 57% to 88% for actionability. PEMs continue to be written at a level above the recommended GRL across all provinces, and there was overall high variability in the quality, understandability, and actionability of PEMs among provincial agencies. This represents an opportunity to optimize materials, thus ensuring understanding by a wider audience and improving health literacy among Canadian cancer patients.

How readable are orthognathic surgery consent forms?

BACKGROUND/OBJECTIVE

The valid consent process for medical intervention requires the disclosure of information in a format that is easily understandable by the patient. The aim of this investigation was to assess the readability of orthognathic surgery informed consent forms (OSICFs).

METHODS

An online search methodology was conducted to identify OSICFs for analysis. The forms that satisfied inclusion/exclusion criteria were evaluated according to a standardised protocol. The readability of the content was assessed using three validated tools: the Simple Measure of Gobbledegook (SMOG) score, Flesch-Kincaid Grade-Level (FKGL) score and Flesch Reading Ease (FRE) score.

RESULTS

Most of the 26 evaluated OSICFs were sourced from websites within the United States (69.2%) and from oral and maxillo-facial surgery practices (76.9%). Two of the assessed forms were template OSICFs available from oral and maxillo-facial professional societies to its members. The scores from the three tools found that the content of 84.6% to 92.3% of the forms were "difficult" to read. The mean (SD) SMOG score for all evaluated OSICFs was 12.31(2.22) [95% CI: 11.42 to 13.21]. The SMOG and FKGL scores were closely correlated (r=0.99, P < 0.0001; 95% CI: 0.9864 to 0.9973). There was no association between SMOG scores and the number of words contained within each consent form (r=-0.047;95% CI: -0.44 to 0.36).

CONCLUSIONS

The OSICFs surveyed in this investigation failed to meet recommended readability levels. A significant number of patients are not likely to understand the information contained within the forms. Orthodontists are advised that poor literacy skills of their patients may preclude them from validly consenting to orthognathic surgery treatment procedures.

Surgical under-treatment of older adult patients with cancer: A systematic review and meta-analysis

BACKGROUND

Older patients with cancer often have lower surgery rates and survival than younger patients, but this may reflect surgical contraindications of advanced disease, comorbidities, and frailty - and not necessarily under-treatment.

OBJECTIVES

This review aims to describe variations in surgery rates and observed or net survival among younger (<75) and older (≥75) patients with breast, lung and colorectal cancer, while taking account of pre-existing health factors, in order to understand how under-treatment is defined and estimated in the literature.

METHOD

MEDLINE, EMBASE, Web of Science and PubMed databases were searched for studies reporting surgery rates and observed or net survival among younger and older patients with breast, lung, and colorectal cancer. Study quality was assessed using the Newcastle Ottawa Scale, and random effects meta-analyses were used to combine study results. The I-squared statistic and subgroup analyses were used to assess heterogeneity.

RESULTS

Thirty relatively high-quality studies of patients with breast (230,200; 71.9%), lung (77,573; 24.2%), and colorectal (12,407; 3.9%) cancers were identified. Compared to younger patients, older patients were less likely to receive surgical treatment for 1) breast cancer after adjusting for comorbidity, performance status (PS), functional status and patient choice, 2) lung cancer after accounting for stage, comorbidity, PS, and 3) colorectal cancer after adjusting for stage, comorbidity, and gender. The pooled unadjusted analyses showed lower surgery receipt in older patients with breast (odds ratio [OR] 0.31, 95% confidence interval [CI] 0.13-0.78), lung (OR 0.54, 95% CI 0.39-0.75), and colorectal (OR 0.59, 95% CI 0.51-0.68) cancer. In separate analyses, older patients with breast, lung and colorectal cancer had lower observed and net survival, compared to younger patients.

CONCLUSIONS

Lower surgery rates in older patients may contribute to their poorer survival compared to younger patients. Future research quantifying under-treatment should include necessary clinical factors, patient choice, patient's quality of life and a statistically-robust approach, which will demonstrate how much of the survival deficit in older patients is due to their receiving lower surgery rates.

Assessment of the Readability of Web-Based Patient Education Material From Major Canadian Pediatric Associations: Cross-sectional Study

BACKGROUND

Web-based patient education materials (PEMs) are frequently written above the recommended reading level in North America. Poor PEM readability limits the accessibility of medical information for individuals with average literacy levels or lower. Pediatric hospital and association websites have not only been shown to be a preferred source of information among caregivers but have also become a necessity during the COVID-19 pandemic. The readability of Canadian pediatric association websites has not yet been assessed.

OBJECTIVE

The aim of this study is to determine if the content of PEMs from Canadian pediatric associations is written at a reading level that the majority of Canadians can understand.

METHODS

A total of 258 PEMs were extracted from 10 Canadian pediatric associations and evaluated for their reading level using 10 validated readability scales. The PEMs underwent a difficult word analysis and comparisons between PEMs from different associations were conducted.

RESULTS

Web-based PEMs were identified from 3 pediatric association websites, where the reading level (calculated as a grade level) was found to be an average of 8.8 (SD 1.8) for the Caring for Kids website, 9.5 (SD 2.2) for the Pediatric Endocrine Group website, and 13.1 (SD 2.1) for the Atlantic Pediatric Society website. The difficult word analysis identified that 19.9% (SD 6.6%) of words were unfamiliar, with 13.3% (SD 5.3%) and 31.9% (SD 6.1%) of words being considered complex (≥3 syllables) and long (≥6 letters), respectively.

CONCLUSIONS

The web-based PEMs were found to be written above the recommended seventh-grade reading level for Canadians. Consideration should be made to create PEMs at an appropriate reading level for both patients and their caregivers to encourage health literacy and ultimately promote preventative health behaviors and improve child health outcomes.

Assessment of parent understanding in conferences for critically ill neonates

OBJECTIVES

This study aimed to characterize the use and impact of assessments of understanding in parent-clinician communication for critically ill infants.

METHODS

We enrolled parents and clinicians participating in family conferences for infants with neurologic conditions. Family conferences were audio recorded as they occurred. We used a directed content analysis approach to identify clinician assessments of understanding and parent responses to those assessments. Assessments were classified based on an adapted framework; responses were characterized as "absent," "yes/no," or "elaborated."

RESULTS

Fifty conferences involving the care of 25 infants were analyzed; these contained 374 distinct assessments of understanding. Most (n = 209/374, 56%) assessments were partial (i.e. okay?); a minority (n = 60/374, 16%) were open-ended. When clinicians asked open-ended questions, parents elaborated in their answers most of the time (n = 55/60, 92%). Approximately three-quarter of partial assessments yielded no verbal response from parents. No conferences included a teach-back.

CONCLUSIONS

Although common, most clinician assessments of understanding were partial or close-ended and rarely resulted in elaborated responses from parents. Open-ended assessments are an effective, underutilized strategy to increase parent engagement and clinician awareness of information needs.

PRACTICE IMPLICATIONS

Clinicians hoping to facilitate parent engagement and question-asking should rely on open-ended statements to assess understanding.

Tele-consent using mixed reality glasses (NREAL) in pediatric inguinal herniorrhaphy: a preliminary study

There is an increasing demand and need for patients and caregivers to actively participate in the treatment process. However, when there are unexpected findings during pediatrics surgery, access restrictions in the operating room may lead to a lack of understanding of the medical condition, as the caregivers are forced to indirectly hear about it. To overcome this, we designed a tele-consent system that operates through a specially constructed mixed reality (MR) environment during surgery. We enrolled 11 patients with unilateral inguinal hernia and their caregivers among the patients undergoing laparoscopic inguinal herniorrhaphy between January through February 2021. The caregivers were informed of the intraoperative findings in real-time through MR glasses outside the operating room. After surgery, we conducted questionnaire surveys to evaluate the satisfaction and usefulness of tele-consent. We identified contralateral patent processus vaginalis in seven out of 11 patients, and then additionally performed surgery on the contralateral side with tele-consent from their caregivers. Most caregivers and surgeons answered positively about the satisfaction and usefulness of tele-consent. This study found that tele-consent with caregivers using MR glasses not only increased the satisfaction of caregivers and surgeons, but also helped to accommodate real-time findings by adapting surgical plan through the tele-consent.

Assessment of the Readability and Quality of Online Patient Education Material for Chronic Medical Conditions

Patient education materials (PEMs) were assessed from chronic health condition associations to determine their quality and if they were above the 6th grade reading level (GRL) recommended by the Centers for Disease Control and National Institutes of Health. PEMs from 55 associations were assessed for their GRL using ten readability scales and underwent a difficult word analysis. The associations had their quality assessed using two methods: the Journal of the American Medical Association (JAMA) Benchmarks and Health on the Net Foundation Code of Conduct certification (HONCode). Two thousand five hundred and ninety PEMs, collected between June and November 2021, were analyzed. The overall GRL average was 10.8 ± 2.8, with a range of 0 to 19. Difficult word analysis showed that 15.8% ± 4.8 contained complex words of 3 or more syllables and 25.7% ± 6.3 contained words which were unfamiliar. No association displayed all four indicators of quality according to JAMA Benchmarks or held an up-to-date HONCode certification. The PEM readability continues to be written at a level above the recommended GRL. Additionally, the lack of quality indicators from the associations’ websites may make it difficult for older adults to identify the sources as credible. This represents an opportunity to optimize materials that would be understood by a wider audience.

An Evaluation of the Comprehensibility Levels of Ophthalmology Surgical Consent Forms

Background/Aim

This study aimed to evaluate the comprehensibility of the consent forms used for interventional procedures in the ophthalmology clinic of a university hospital and to determine which texts could be read according to patient age and education level.

Materials and methods

Forty separate consent forms used as the standard for various interventional procedures in the ophthalmology department of a university hospital were evaluated. The comprehensibility formulas used were developed for the Turkish language by Ateşman and Bezirci-Yilmaz.

Results

As a result of the evaluation of the consent forms in this study, a mean of 55.6±5.73 points was obtained according to the Ateşman comprehensibility index, and this value was found to correspond to being understood by eleventh and twelfth-grade school students. According to the Bezirci-Yilmaz comprehensibility index, the mean points of the consent forms were 10.05±2, which corresponded to a level that could be understood by 10th and 11th-grade students.

Conclusion

The comprehensibility level of the consent forms given to patients was found to be low in this study, which was similar to the findings of previous studies in the literature. When preparing informed consent forms, the education level of the country must be taken into consideration.

Readability of Patient Education Materials From High-Impact Medical Journals: A 20-Year Analysis

Comprehensive patient education is necessary for shared decision-making. While patient–provider conversations primarily drive patient education, patients also use published materials to enhance their understanding. In this investigation, we evaluated the readability of 2585 patient education materials published in high-impact medical journals from 1998 to 2018 and compared our findings to readability recommendations from national groups. For all materials, mean readability grade levels ranged from 11.2 to 13.8 by various metrics. Fifty-four (2.1%) materials met the American Medical Association recommendation of sixth grade reading level, and 215 (8.2%) met the National Institutes of Health recommendation of eighth grade level. When stratified by journal and material type, general medical education materials from Annals of Internal Medicine were the most readable (P < .001), with 79.8% meeting the eighth grade level. Readability did not differ significantly over time. Efforts to standardize publication practice with the incorporation of readability evaluation during the review process may improve patients’ understanding of their disease processes and treatment options.

Health Services: A Mixed Methods Assessment of Canadian Cancer Patient Education Materials Related to the 2019 Novel Coronavirus

The 2019 novel coronavirus (COVID-19) pandemic has prompted the reorganization in the scheduling and method of care for many patients, including patients diagnosed with cancer. Cancer patients, who have an immunocompromised status, may be at a higher risk of severe symptoms from infection with COVID-19. While information is rapidly evolving regarding COVID-19, Canada, both nationally and provincially, has been conveying new information to patients online. We assessed the content and readability of COVID-19-related online Canadian patient education material (PEM) for cancer patients to determine if the content of the material was written at a grade reading level that the majority of Canadians can understand. PEMs were extracted from provincial cancer agencies and the national Canadian Cancer Society, evaluated using 10 readability scales, qualitatively analyzed to identify their themes and difficult word content. Thirty-eight PEMs from both national and provincial cancers associations were, on average, written above the recommended 7th grade level. Each of the associations' average grade levels were: BC Cancer (11.00 95% confidence interval [CI] 8.27-13.38), CancerControl Alberta (10.46 95% CI 8.29-12.62), Saskatchewan Cancer Agency (11.08 95% CI 9.37-12.80), Cancer Care Manitoba (9.55 95% CI 6.02-13.01), Cancer Care Ontario (9.35 95% CI 6.80-11.90), Cancer Care Nova Scotia (10.95 95% CI 9.86-12.04), Cancer Care Eastern Health Newfoundland and Labrador (10.14 95% CI 6.87-13.41), and the Canadian Cancer Society (10.06 95% CI 8.07-12.05). Thematic analysis identified 4 themes: public health strategy, information about COVID-19, patient instructions during COVID-19, and resources. Fifty-three percent of the complex words identified were medical jargon. This represents an opportunity to improve PEM readability, to allow for greater comprehension amongst a wider target audience.

Assessment of the Readability of Online Patient Education Material from Major Geriatric Associations

BACKGROUND/OBJECTIVES

An increasing number of patients are using the internet to supplement information provided by medical professionals. Online geriatric patient education materials (PEMs) should be written at or below a 6th grade reading level (GRL) that takes into account barriers unique to the geriatric population. The objectives of the study are to assess PEMs of geriatric associations' websites and determine whether they are above the GRL recommended by the Centers for Disease Control and National Institutes of Health.

DESIGN

Descriptive and correlational methodology. PEMs from 10 major geriatric associations were assessed for their GRL using 10 scales. Eight of the scales provide a numerical GRL while two of the scales provide a visual representation of the GRLs. Analysis was conducted using Readability Studio 2019.3.

SETTING

Analysis was conducted February 2020.

PARTICIPANTS

Identified 10 geriatric associations and 884 PEMs.

MEASUREMENTS

GRLs were measured by 10 validated readability indices: the Degrees of Reading Power and Grade Equivalent test, Flesch-Kincaid grade level, Simple Measure of Gobbledygook test, Coleman-Liau Index, Gunning Fog Index, New Fog Count, New Dale-Chall readability formula, Ford, Caylor, Sticht scale, Raygor readability estimate graph, and Fry readability graph.

RESULTS

The mean of all PEMs using the numerical scales was 11.1 ± 2.4. Ninety-nine percent of PEMs are above the 6th GRL. PEMs ranged from a grade 3.0 to 19.0 reading level. Analysis of variance demonstrated a significant difference between associations (P < .0001), and multiple comparison analysis identified the National Institute on Aging as the content easiest to read (9.5 ± 1.6).

CONCLUSION

PEMs from geriatric association websites are written above the recommended 6th GRL. As patients increasingly look toward online supplementary health information during COVID-19, there is an opportunity for improving PEMs to enable greater comprehension by the target population.

Assessment of Canadian patient education material for oncology pharmaceutics

Introduction

Health literacy is an individual’s ability to access, understand, and utilize information in order to create an informed decision regarding their health. Readability plays an integral role in health literacy as complex health information may be inaccessible to those with low health literacy. The aim of this study is to determine the readability of Canadian patient education material (PEM) for oncology related pharmaceutics.

Methods

Eighty PEMs from Cancer Care Ontario (CCO) and BC Cancer (BCC) were evaluated for their reading level using a Ford, Caylor, Sticht (FORCAST) analysis. Twenty therapies were then randomly selected and converted to plain text to be analyzed further using the Flesch-Kincaid Grade Level (FKGL), the Simple Measure of Gobbledygook (SMOG) Index, the Coleman-Liau Index (CLI), and the Gunning Fog Index (GFI).

Results

Both PEMs from CCO and BCC were above the recommended reading level with PEMs from CCO, on average, requiring a higher reading level. Within the text, the section which describes side effects was found to be the most complex section of the representative PEMs from BCC. PEMs from BCC which described antibody-based therapies were, on average, more difficult to read than small molecule-based therapies regardless from which section the PEM was being analyzed. These observations were not seen in CCO PEMs.

Conclusions

Overall, online PEMs from major Canadian cancers associations were written above the recommended reading level. Consideration should be given to revision of these materials, with emphasis on the therapies’ side effects, to allow for greater comprehension amongst a wider target audience.

Evaluation of the Informational Content and Readability of US Lung Cancer Screening Program Websites

IMPORTANCE

The internet is an important source of medical information for many patients and may have a key role in the education of patients about lung cancer screening (LCS). Although most LCS programs in the United States have informational websites, the accuracy, completeness, and readability of these websites have not previously been studied.

OBJECTIVE

To evaluate the informational content and readability of US LCS program websites.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study assessed US LCS program websites identified on September 15, 2018. A standardized checklist was used to assess key informational content of each website, and text was analyzed for reading level, word count, and reading time. Links to US websites of national advocacy organizations with LCS program content were tabulated. All functional LCS program websites in Google internet search engine results using the search terms lung cancer screening, low-dose CT screening, and lung screening were included in the analysis.

MAIN OUTCOMES AND MEASURES

Radiologists used a standardized checklist to evaluate content, and readability was assessed with validated scales. Website word count, reading time, and number of links to outside LCS informational websites were assessed.

RESULTS

A total of 257 LCS websites were included in the analysis. The word count ranged from 73 to 4410 (median, 571; interquartile range, 328-909). The reading time ranged from 0.3 to 19.6 minutes (median, 2.5; interquartile range, 1.5-4.0). The median reading level of all websites was grade 10 (interquartile range, 9-11). Only 26% (n = 66) of websites had at least 1 web link to a national website with additional information on LCS. There was wide variability regarding reported eligibility age criteria, with ages 55 to 77 years most frequently cited (42% [n = 108]). Only 56% (n = 143) of websites mentioned smoking cessation. The subject of patient cost was mentioned on 75% (n = 192) of websites. Although major LCS benefits, such as detection of lung cancer, were discussed by most (93% [n = 239]) websites, less than half of the websites (45% [n = 115]) made any mention of possible risks associated with screening.

Prospective Decision Analysis Study of Clinical Genomic Testing in Metastatic Breast Cancer: Impact on Outcomes and Patient Perceptions

PURPOSE

To evaluate the impact of targeted DNA sequencing on selection of cancer therapy for patients with metastatic breast cancer (MBC).

PATIENTS AND METHODS

In this prospective, single-center, single-arm trial, patients with MBC were enrolled within 10 weeks of starting a new therapy. At enrollment, tumor samples underwent next-generation sequencing for any of 315 cancer-related genes to high depth (> 500×) using FoundationOne CDx. Sequencing results were released to providers at the time of disease progression, and physician treatment recommendations were assessed via questionnaire. We evaluated three prespecified questions to assess patients' perceptions of genomic testing.

RESULTS

In all, 100 patients underwent genomic testing, with a median of five mutations (range, 0 to 13 mutations) detected per patient. Genomic testing revealed one or more potential therapies in 98% of patients (98 of 100), and 60% of patients (60 of 100) had one or more recommended treatments with level I/II evidence for actionability. Among the 94 genomic text reports that were released, there was physician questionnaire data for 87 patients (response rate, 92.6%) and 31.0% of patients (27 of 87) had treatment change recommended by their physician. Of these, 37.0% (10 of 27) received the treatment supported by genomic testing. We did not detect a statistically significant difference in time-to-treatment failure (log-rank P = .87) or overall survival (P = .71) among patients who had treatment change supported by genomic testing versus those who had no treatment change. For patients who completed surveys before and after genomic testing, there was a significant decrease in confidence of treatment success, specifically among patients who did not have treatment change supported by genomic testing (McNemar's test of agreement P = .001).

CONCLUSION

In this prospective study, genomic profiling of tumors in patients with MBC frequently identified potential treatments and resulted in treatment change in a minority of patients. Patients whose therapy was not changed on the basis of genomic testing seemed to have a decrease in confidence of treatment success.
