Online information on dysmenorrhoea: An evaluation of readability, credibility, quality and usability

Assessing the Quality and Readability of Online Patient Information: ENT UK Patient Information e-Leaflets versus Responses by a Generative Artificial Intelligence

BACKGROUND

 The evolution of artificial intelligence has introduced new ways to disseminate health information, including natural language processing models like ChatGPT. However, the quality and readability of such digitally generated information remains understudied. This study is the first to compare the quality and readability of digitally generated health information against leaflets produced by professionals.

METHODOLOGY

 Patient information leaflets from five ENT UK leaflets and their corresponding ChatGPT responses were extracted from the Internet. Assessors with various degrees of medical knowledge evaluated the content using the Ensuring Quality Information for Patients (EQIP) tool and readability tools including the Flesch-Kincaid Grade Level (FKGL). Statistical analysis was performed to identify differences between leaflets, assessors, and sources of information.

RESULTS

 ENT UK leaflets were of moderate quality, scoring a median EQIP of 23. Statistically significant differences in overall EQIP score were identified between ENT UK leaflets, but ChatGPT responses were of uniform quality. Nonspecialist doctors rated the highest EQIP scores, while medical students scored the lowest. The mean readability of ENT UK leaflets was higher than ChatGPT responses. The information metrics of ENT UK leaflets were moderate and varied between topics. Equivalent ChatGPT information provided comparable content quality, but with reduced readability.

CONCLUSION

 ChatGPT patient information and professionally produced leaflets had comparable content, but large language model content required a higher reading age. With the increasing use of online health resources, this study highlights the need for a balanced approach that considers both the quality and readability of patient education materials.

Websites about, not for, adolescents? A systematic analysis of online fertility preservation information for adolescent and young adult cancer patients

PURPOSE

Fertility preservation is an increasingly important topic in adolescent and young adult cancer survivorship, yet treatments remain under-utilized, possibly due to lack of awareness and understanding. The internet is widely used by adolescents and young adults and has been proposed to fill knowledge gaps and advance high-quality, more equitable care. As a first step, this study analyzed the quality of current fertility preservation resources online and identified opportunities for improvement.

METHODS

We conducted a systematic analysis of 500 websites to assess the quality, readability, and desirability of website features, and the inclusion of clinically relevant topics.

RESULTS

The majority of the 68 eligible websites were low quality, written at college reading levels, and included few features that younger patients find desirable. Websites mentioned more common fertility preservation treatments than promising experimental treatments, and could be improved with cost information, socioemotional impacts, and other equity-related fertility topics.

CONCLUSIONS

Currently, the majority of fertility preservation websites are about, but not for, adolescent and young adult patients. High-quality educational websites are needed that address outcomes that matter to teens and young adults, with a priority on solutions that prioritize equity.

IMPLICATIONS FOR CANCER SURVIVORS

Adolescent and young adult survivors have limited access to high-quality fertility preservation websites that are designed for their needs. There is a need for the development of fertility preservation websites that are clinically comprehensive, written at appropriate reading levels, inclusive, and desirable. We include specific recommendations that future researchers can use to develop websites that could better address AYA populations and improve the fertility preservation decision making process.

High-Quality eHealth Websites for Information on Endometriosis: Systematic Search

BACKGROUND

eHealth websites are increasingly being used by community members to obtain information about endometriosis. Additionally, clinicians can use these websites to enhance their understanding of the condition and refer patients to these websites. However, poor-quality information can adversely impact users. Therefore, a critical evaluation is needed to assess and recommend high-quality endometriosis websites.

OBJECTIVE

This study aimed to evaluate the quality and provide recommendations for high-quality endometriosis eHealth websites for the community and clinicians.

METHODS

PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) 2020 guidelines informed 2 Google searches of international and Australian eHealth websites. The first search string used the terms "endometriosis," "adenomyosis," or "pelvic pain," whereas "Australia" was added to the second search string. Only free eHealth websites in English were included. ENLIGHT, a validated tool, was used to assess the quality across 7 domains such as usability, visual design, user engagement, content, therapeutic persuasiveness, therapeutic alliance, and general subjective evaluation. Websites with a total score of 3.5 or more were classified as "good" according to the ENLIGHT scoring system and are recommended as high-quality eHealth websites for information on endometriosis.

RESULTS

In total, 117 eHealth websites were screened, and 80 were included in the quality assessment. Four high-quality eHealth websites (ie, those that scored 3.5 or more) were identified (Endometriosis Australia Facebook Page, Endometriosis UK, National Action Plan for Endometriosis on EndoActive, and Adenomyosis by the Medical Republic). These websites provided easily understood, engaging, and accurate information. Adenomyosis by the Medical Republic can be used as a resource in clinical practice. Most eHealth websites scored well, 3.5 or more in the domains of usability (n=76, 95%), visual design (n=64, 80%), and content (n=63, 79%). However, of the 63 websites, only 25 provided references and 26 provided authorship details. Few eHealth websites scored well on user engagement (n=18, 23%), therapeutic persuasiveness (n=2, 3%), and therapeutic alliance (n=22, 28%). In total, 30 (38%) eHealth websites scored well on general subjective evaluation.

CONCLUSIONS

Although geographical location can influence the search results, we identified 4 high-quality endometriosis eHealth websites that can be recommended to the endometriosis community and clinicians. To improve quality, eHealth websites must provide evidence-based information with appropriate referencing and authorship. Factors that enhance usability, visual design, user engagement, therapeutic persuasiveness, and therapeutic alliance can lead to the successful and long-term uptake of eHealth websites. User engagement, therapeutic persuasiveness, and therapeutic alliance can be strengthened by sharing lived experiences and personal stories and by cocreating meaningful content for both the community and clinicians. Reach and discoverability can be improved by leveraging search engine optimization tools.

Online information on chronic pain in 3 countries: an assessment of readability, credibility, and accuracy

Objectives

To assess the readability, credibility, and accuracy of online information on chronic pain in Australia, Mexico, and Nepal.

Methods

We assessed Google-based websites and government health websites about chronic pain for readability (using the Flesch Kincaid Readability Ease tool), credibility (using the Journal of American Medical Association [JAMA] benchmark criteria and Health on the Net Code [HONcode]), and accuracy (using 3 core concepts of pain science education: (1) pain does not mean my body is damaged; (2) thoughts, emotions, and experiences affect pain; and (3) I can retrain my overactive pain system).

Results

We assessed 71 Google-based websites and 15 government websites. There were no significant between-country differences in chronic pain information retrieved through Google for readability, credibility, or accuracy. Based on readability scores, the websites were "fairly difficult to read," suitable for ages 15 to 17 years or grades 10 to 12 years. For credibility, less than 30% of all websites met the full JAMA criteria, and more than 60% were not HONcode certified. For accuracy, all 3 core concepts were present in less than 30% of websites. Moreover, we found that the Australian government websites have low readability but are credible, and the majority provided all 3 core concepts in pain science education. A single Mexican government website had low readability without any core concepts but was credible.

Conclusion

The readability, credibility, and accuracy of online information on chronic pain should be improved internationally to support facilitating better management of chronic pain.

Analysis of the quality, accuracy, and readability of patient information on polycystic ovarian syndrome (PCOS) on the internet available in English: a cross-sectional study

BACKGROUND

Online information about PCOS lacks reliability for patients seeking information about the disease. Thus, we aimed to perform an updated analysis of the quality, accuracy, and readability of patient information on PCOS available online.

METHODS

We conducted a cross-sectional study using the top five Google Trends search terms in English associated with PCOS, including "symptoms," "treatment," "test," "pregnancy," and "causes." Five separate searches in Bing, Yahoo, and Google were performed to obtain the first 10 unique webpages for each term that was categorized as commercial, non-profit organization, scientific resources, or private foundation. We used the 16-item DISCERN with Likert-responses (minimum 1, maximum 5) where the total is 80 and lowest is 16, clarity with the 32-item EQIP, where responses of no = 0 and yes = 1 (minimum 0, maximum 32), and accuracy scores with 1 denoting poor and 5 completely accurate information; low scores of each corresponded to poorly reported information. We assessed readability with Flesch-Kincaid reading ease index, where higher scores correspond to reading ease, and lower grades correspond to easier readability with Flesch-Kincaid grade level, Gunning-Fog, Coleman-Liau index, automated readability index, New Dale-Chall Readability, and simple measure of gobbledygook. We additionally assessed word and sentence characteristics. We used Kruskal-Wallis test to compare scores according to webpage categories.

RESULTS

Out of 150 webpages, most were commercial (n = 85, 57%), followed by non-profit organizations (n = 44, 29%), scientific resources (n = 13, 9%) and private foundations (n = 6, 4%). Google webpages had higher median DISCERN score ([Md] = 47.0) than Bing ([Md] = 42.0) and Yahoo ([Md] = 43.0) webpages; P = 0.023. No difference in EQIP scores according to search engine was found (P = 0.524). Predominantly, webpages from private foundations had higher DISCERN and EQIP scores, although comparisons were not statistically significant (P = 0.456) and P = 0.653.). Accuracy and readability were similar across search engines and webpage categories (P = 0.915, range 5.0-5.0) and (P = 0.208, range 4.0-5.0).

CONCLUSIONS

Quality and clarity of the data were fair according to search engine and category. Accuracy of information was high, showing that the public may encounter accurate information about PCOS. However, the readability of the information was high, reflecting a need for more readable resources about PCOS.

Evaluation of quality, readability, suitability, and usefulness of online resources available to cancer survivors

PURPOSE

The aim of this study was to evaluate the quality, readability, suitability, and usefulness of resources publicly available to adult cancer survivors (aged 18 +) who have completed primary treatment.

METHODS

Resources were identified in July 2021 through Google. Search completeness was verified using Yahoo, Bing, and MedlinePlus. Retrieved resources were assessed for quality using the DISCERN, readability, suitability using the Suitability Assessment Measure (SAM), and usefulness based on a list of unmet needs and self-management skills derived from the literature. Descriptive analyses were conducted, and a cluster analysis identified the highest-scoring resources.

RESULTS

Forty-five resources were included. The mean DISCERN score was fair at 63.3% (SD 13.7%) with low-rated items being sources, publication date, and risks and mechanisms of treatment. The mean reading grade level was 11.19 (SD 1.61, range 8-16) with only one resource scoring an 8. The mean SAM score was in the adequate range at 48.2% (SD 10.6%), with graphics being the lowest-rated section. On average, included resources addressed 57.7% (SD 27.3%) of the unmet needs and 48.4% (SD 20.9%) of the self-management skills, the least addressed being problem-solving.

CONCLUSION

Quality and suitability were fair, whereas readability exceeded recommended levels. Only one resource had a superior score in both quality and suitability.

IMPLICATIONS FOR CANCER SURVIVORS

The most pressing need is to develop resources for cancer survivors that address their unmet needs and are accessible in terms of literacy. Study findings outline the highest-scoring resources currently available to survivors, families, and clinicians.

What Patients Find on the Internet When Looking for Information About Percutaneous Coronary Intervention: Multilanguage Cross-sectional Assessment

BACKGROUND

The internet provides general users with wide access to medical information. However, regulating and controlling the quality and reliability of the considerable volume of available data is challenging, thus generating concerns about the consequences of inaccurate health care-related documentation. Several tools have been proposed to increase the transparency and overall trustworthiness of medical information present on the web.

OBJECTIVE

We aimed to analyze and compare the quality and reliability of information about percutaneous coronary intervention on English, German, Hungarian, Romanian, and Russian language websites.

METHODS

Following a rigorous protocol, 125 websites were selected, 25 for each language sub-sample. The websites were assessed concerning their general characteristics, compliance with a set of eEurope 2002 credibility criteria, and quality of the informational content (namely completeness and accuracy), based on a topic-specific benchmark. Completeness and accuracy were graded independently by 2 evaluators. Scores were reported on a scale from 0 to 10. The 5 language subsamples were compared regarding credibility, completeness, and accuracy. Correlations between credibility scores on the one hand, and completeness and accuracy scores, on the other hand, were tested within each language subsample.

RESULTS

The websites' compliance with credibility criteria was average at best with scores between 3.0 and 6.0. In terms of completeness and accuracy, the website subsets qualified as poor or average, with scores ranging from 2.4 to 4.6 and 3.6 to 5.3, respectively. English language websites scored significantly higher in all 3 aspects, followed by German and Hungarian language websites. Only German language websites showed a significant correlation between credibility and information quality.

CONCLUSIONS

The quality of websites in English, German, Hungarian, Romanian, and Russian languages about percutaneous coronary intervention was rather inadequate and may raise concerns regarding their impact on informed decision-making. Using credibility criteria as indicators of information quality may not be warranted, as credibility scores were only exceptionally correlated with content quality. The study brings valuable descriptive data on the quality of web-based information regarding percutaneous coronary intervention in multiple languages and raises awareness about the need for responsible use of health-related web resources.

The Impact of Popular Science Articles by Physicians on Their Performance on Online Medical Platforms

The public demand for popular science knowledge regarding health is increasing, and physicians' popular science practices on online medical platforms are becoming frequent. Few studies have been conducted to address the relationship between specific characteristics of popular science articles by physicians and their performance. This study explored the impact of the characteristics of popular science articles on physicians' performance based on the elaboration likelihood model (ELM) from the central path (topic focus and readability) and the peripheral path (form diversity). Data on four diseases, namely, lung cancer, brain hemorrhage, hypertension, and depression, were collected from an online medical platform, resulting in relevant personal data from 1295 doctors and their published popular science articles. Subsequently, the independent variables were quantified using thematic analysis and formula calculation, and the research model and hypotheses proposed in this paper were verified through empirical analysis. The results revealed that the topic focus, readability, and form diversity of popular science articles by physicians had a significant positive effect on physicians' performance. This study enriches the research perspective on the factors influencing physicians' performance, which has guiding implications for both physicians and platforms, thereby providing a basis for patients to choose physicians and enabling patients to receive popular science knowledge regarding health in an effective manner.

Quality and readability of online information on plantar fasciitis and calcaneal spur

Plantar fasciitis and calcaneal spur are common causes of heel pain in the community. People use the Internet to obtain medical information about diseases. We reviewed Internet information sources on plantar fasciitis and calcaneal spur for quality and readability. The first 50 websites for each search term ("calcaneal spur", "heel spur", and "plantar fasciitis") were scanned on www.google.com . Six different valid tools were used for information quality and readability assessment. We searched for HONCode (Health On the Net Foundation Code) stamps on included websites. The total mean points for DISCERN were 50.52 ± 14.62, and the total mean points for JAMA (Journal of the American Medical Association) were 2.42 ± 1.26. In total, 25.72% of 97 websites had HONCode stamps. The average scores for the readability indicators were calculated to be Flesch-Kincaid Grade Level (FKGL): 7.27 ± 1.71, Gunning Fog: 8.46 ± 2.17, Simple Measure of Gobbledygook (SMOG): 6.89 ± 1.24, and Coleman Liau Index: 15.56 ± 1.85. In our study, when the website resources were examined, there were profit websites the most and website quality and readability were moderate level. A significant proportion of the websites have a financial bias and provide low-quality information. A mechanism for monitoring the quality and readability of online information must be established and managed systematically.

Assessing the knowledge of endometriosis diagnostic tools in a large, international lay population: an online survey

OBJECTIVE

To assess the general population's knowledge regarding the utility and availability of tools to diagnosis endometriosis, with a focus on ultrasound.

DESIGN

An international cross-sectional online survey study was performed between August and October 2019.

SETTING AND POPULATION

5301 respondents, representing 73 countries.

METHODS

In all, 23 questions survey focused on knowledge of endometriosis diagnosis distributed globally via patient- and community-endometriosis groups using social media.

MAIN OUTCOMES AND MEASURES

Descriptive data of the knowledge of diagnostic tools for diagnosing endometriosis, including details about diagnosis using ultrasound.

RESULTS

In all, 84.0% of respondents had been previously diagnosed with endometriosis, 71.5% of whom had been diagnosed at the time of surgery. Ultrasound and MRI were the methods of diagnosis in 6.5% and 1.8%, respectively. A total of 91.8%, 28.8% and 16.6% of respondents believed surgery, ultrasound and MRI could diagnose endometriosis, respectively (more than one answer allowed). In those diagnosed by surgery, 21.7% knew about ultrasound as a diagnosis method, whereas in those diagnosed non-surgically, 51.5% knew (P < 0.001). In all, 14.7%, 31.1% and 18.2% stated superficial, ovarian and deep endometriosis could be diagnosed with ultrasound (32.9% stated they did not know which phenotypes of endometriosis could be diagnosed). Lastly, 58.4% of respondents do not believe they could access an advanced ultrasound in their region.

CONCLUSIONS

There is a limited appreciation for the role of non-surgical diagnostic tests for endometriosis among lay respondents to this survey.

TWEETABLE ABSTRACT

International survey shows limited awareness of lay respondents about non-surgical endometriosis diagnostic tools.

Quality and Readability of Web-Based Information for Patients With Pancreatic Cysts: DISCERN and Readability Test Analysis

Background

Pancreatic cysts are a complex medical problem with several treatment options. Patients use web-based health information to understand their conditions and to guide treatment choices.

Objective

The goal of this study was to describe the quality and readability of publicly available web-based information on pancreatic cysts and to compare this information across website affiliations.

Methods

A Google search for “pancreatic cysts” was performed and the first 30 websites were evaluated. Website affiliations were classified as academic, media, nonprofit, government, or not disclosed. Information describing cancer risk was recorded. The DISCERN instrument measured the quality of content regarding treatment choices. Four standardized tests were used to measure readability.

Results

Twenty-one websites were included. The majority of the websites (20/21, 95%) described the cancer risk associated with pancreatic cysts. Nearly half of the websites were written by an academic hospital or organization. The average DISCERN score for all websites was 40.4 (range 26-65.5, maximum 80). Websites received low scores due to lack of references, failure to describe the risks of treatment, or lack of details on how treatment choices affect quality of life. The average readability score was 14.74 (range 5.76-23.85, maximum 19+), indicating a college reading level. There were no significant differences across website affiliation groups.

Conclusions

Web-based information for patients with pancreatic cysts is of moderate quality and is written above the reading level of most Americans. Gastroenterological, cancer treatment organizations, and physicians should advocate for improving the available information by providing cancer risk stratification, treatment impact on quality of life, references, and better readability.

An evaluation of the quality of online information on emergency contraception

OBJECTIVES

The increasing availability of health information online combined with reduced access to health care providers due to the coronavirus pandemic means that more people are using the internet for health information. However, with no standardised regulation of the internet, the population is vulnerable to misinformation regarding important health information. This review aimed to evaluate the quality and readability of the online information available on emergency contraception (EC) options.

STUDY DESIGN

In this descriptive study, a Google search was performed using the term 'emergency contraception options' on 13 April 2020 yielding 232 results. Seventy-one results were excluded (34 inaccessible, 37 contained no medical information). The remaining 161 results were categorised by typology and assessed for credibility (JAMA criteria and HONcode), reliability (DISCERN tool) and readability (Flesch-Kincaid Grade Level and Simple Measure of Gobbledygook).

RESULTS

Of all webpages evaluated, the most common typology was governmental. Credibility of web pages was poor (average JAMA score of 1.47 out of 4). Only 10.6% of webpages were HONcode certified. The most common DISCERN category was Fair (29.81%), closely followed by Poor (27.95%) reliability. On average, readability levels were above the recommended grade level for health information. The intrauterine device was discussed least frequently (86.96%) of all the EC options.

CONCLUSION

Online information was of low credibility, reliability and written above the recommended reading level. Clinicians should be aware of the poor quality of online information on EC options, and actively educate patients on what makes a source credible.

The effectiveness and safety of acupoint catgut embedding for the treatment of primary dysmenorrhea: A protocol for systematic review and meta-analysis

BACKGROUND

Primary dysmenorrhea (PD), also regarded as functional dysmenorrhea, refers to dysmenorrhea without obvious organic lesions in the reproductive system. It accounts for more than 90% of dysmenorrhea and seriously affects womens life and work. Previous studies have proved that acupoint catgut embedding therapy is effective and safe for PD patients. It could relieve the pain rapidly and work for a long time in multiple mechanisms. This protocol aims to evaluate the effectiveness and safety of acupoint catgut embedding therapy on PD systematically. With the latest published evidence, a systematic review and meta-analysis of catgut embedding for patients with PD would be carried out in this study.

METHODS

All randomized controlled trials (RCTs) related to acupoint catgut embedding therapy on PD will be searched in the following electronic databases: PubMed, Cochrane Library, EMBASE, Wed of Science, Chinese National Knowledge Infrastructure (CNKI), Chongqing VIP Database, Wanfang Database, and Chinese Biomedical Literatures Database (CBM), from inception to September 2020. The primary outcomes contain visual analog scale (VAS), dysmenorrhea symptom score, and clinical effectiveness rate, while the secondary outcomes consist of adverse events and the recurrence rate. Two reviewers will independently perform data selection, data synthesis, and quality assessment. Assessment of risk of bias and data synthesis would be performed with Review Manager 5.3 software.

RESULT

This systematic review will summarize the current and high-quality evidence of acupoint catgut embedding therapy on PD.

CONCLUSION

This systematic review aims to offer the latest persuasive evidence for clinical practitioners that using acupoint catgut embedding therapy on PD is effective and safe.

Credibility evaluation of scientific information on websites: Designing and evaluating an exploratory model

The present study aimed to develop a literature-based and expert-modified model for credibility evaluation of scientific web information in order to be used for academic purposes by utilizing a mixed heuristic method. First, meta-synthesis was applied to design a conceptual model. In terms of its usability, the model was evaluated by a sample of student users in five top universities of Iran. The data were analyzed by SPSS 20.0 and LISREL 8.7 for Structural Equation Modelling. Based on the seven-stage meta-synthesis, a conceptual model, including 68 indicators, 14 components, and two main dimensions was identified. The model was confirmed by the sample experts by considering the high degree of Kendall’s coefficient of concordance and the agreement percentage of most dimensions of the model which were 0.67 and higher than 90%, respectively. Next, the results of confirmatory factor analysis were analyzed according to the structural model and indices related to the goodness of fit in order to ensure a high quality respecting measuring the identified variables. Based on data analysis, the variables were of high quality in the studied context although there were some differences among the dimensions. The results further revealed that credibility evaluation is a concept with different and multiple dimensions and components suitable for users, designers, and policymakers which should be considered in designing and evaluating web resources.
