Readability Assessment of HPV Vaccination and Cervical Cancer Information: A Systematic Scoping Review

Evaluating the understandability and actionability of Japanese human papillomavirus vaccination educational materials on cervical cancer

Educational materials about human papillomavirus (HPV) vaccination must be easy to understand and must support recommended behaviors regardless of readers' health literacy levels. The purpose of this study was to evaluate the understandability, actionability, and comprehensiveness of HPV vaccination educational materials in Japan. From August to September 2023, we obtained HPV vaccination educational materials from the central government, local governments, and websites. We assessed the understandability and actionability of the materials using the Patient Education Materials Assessment Tool for Printed Materials (PEMAT-P), Japanese version. We also evaluated the comprehensiveness of the content. Ratings of understandability, actionability, and comprehensiveness were compared by material type and source. We evaluated 164 eligible materials. The mean understandability and actionability of all materials were 60.5% (standard deviation [SD] = 12.5) and 42.0% (SD = 20.5), respectively. Many materials lacked definitions of medical terms, clear explanations of numbers, content summaries, explicit steps of action, and the use of visual aids to improve understanding and actionability. The mean comprehensiveness score was 73.5% (SD = 14.7%). A few materials included all the necessary information content. The highest understandability score and actionability score were for local government mailings, and the highest comprehensiveness score was for academic materials. Most Japanese HPV vaccination educational materials were insufficiently understandable and actionable. Such materials need to be improved, especially regarding the use of numbers, medical terms, and visual aids. In terms of content, the importance of vaccination before sexual debut and the benefits of vaccination for men should be emphasized.

Both English- and Spanish-Language Anterior Cruciate Ligament Reconstruction Online Patient Education Materials Are Written at Higher-Than-Recommended Reading Levels

Purpose

To examine the overall reading levels of anterior cruciate ligament reconstruction online patient education materials (OPEMs) written in English and Spanish.

Methods

We conducted Google searches for OPEMs using "ACL surgery" and "cirugía LCA" as English and Spanish search terms, respectively. Several measures of readability were used to analyze 25 English-language OPEMs (Flesch Reading Ease, Flesch Reading Ease Grade Level, Flesch-Kincaid Grade Level, Coleman-Liau Index, Gunning Fog Index, and Simple Measure of Gobbledygook) and 25 Spanish-language OPEMs (Fernández-Huerta Index, Fernández-Huerta Grade Level, and Índice de Legibilidad de Flesch-Szigriszt). English- and Spanish-language OPEMs were compared based on mean overall grade level and number of OPEMs written below a seventh- or ninth-grade reading level.

Results

English-language OPEMs showed a higher mean overall grade level than Spanish-language OPEMs (10.48 ± 1.86 vs 8.64 ± 1.22, P < .001). No significant differences were noted in the number of OPEMs written below a seventh-grade reading level. However, significantly more Spanish-language OPEMs were written below a ninth-grade reading level compared with English-language OPEMs (56% vs 16%, P = .003).

Conclusions

Although Spanish-language OPEMs were written at a lower reading level, average readability for both English- and Spanish-language OPEMs was significantly higher than the recommended level. Across both languages, only a single English-language webpage met the American Medical Association-recommended sixth-grade reading level. More Spanish-language articles were written at or below the average adult reading level in the United States.

Clinical Relevance

It is imperative that patient educational materials be written at a reading level that is understood by the most patients. This is especially true for OPEMs, when a medical provider is not present to answer questions. Therefore, it is important to evaluate the reading level of OPEMs to determine whether they are written at an appropriate level for the best patient understanding.

Readability assessment of Spanish online patient education materials in gynecologic oncology

Objective

Over half of Spanish-speaking patients use the internet to understand their diagnosis. We evaluated readability of Spanish online patient education materials (OPEMs) about gynecologic cancer to assess compliance with National Institute of Health (NIH) recommendations to be at or below eighth grade reading level.

Methods

We conducted an online search using six Spanish gynecologic cancer terms on three major search engines with cookies and location disabled. The first five results by cancer type were included. Readability was analyzed by Spanish Simple Measure of Gobbledygook (SMOG) and Gilliam-Peña-Mountain (GPM) indices. One-way ANOVA with Tukey's Honestly Significant Difference (HSD) post-hoc analysis was performed.

Results

322 unique OPEMs were retrieved using Spanish queries. This included 132 (41 %) from non-profit organizations, 114 (35.4 %) from governmental organizations, and 63 (19.5 %) from academic medical centers; the remainder were from professional medical society or pharmaceutical company sources. Overall, gynecologic oncology OPEMs were written at a mean 9.8 ± 1.2 grade reading level. Only 14 % of OPEMs were written at or below an eighth grade reading level. There were significant differences in readability by publishing source (p < 0.001). Though there were no significant differences in readability by cancer type (p = 0.07), the mean reading level for all cancer types was between ninth and eleventh grade level.

Conclusions

86% of readily searchable Spanish gynecologic oncology OPEMs are written above recommended reading levels. Gynecologic oncologists should curate and support Spanish-speaking patients in finding high-quality online educational content.

Readability of Patient Education Materials in Head and Neck Cancer: A Systematic Review

Importance

Patient education materials (PEMs) can promote patient engagement, satisfaction, and treatment adherence. The American Medical Association recommends that PEMs be developed for a sixth-grade or lower reading level. Health literacy (HL) refers to an individual's ability to seek, understand, and use health information to make appropriate decisions regarding their health. Patients with suboptimal HL may not be able to understand or act on health information and are at risk for adverse health outcomes.

Objective

To assess the readability of PEMs on head and neck cancer (HNC) and to evaluate HL among patients with HNC.

Evidence Review

A systematic review of the literature was performed by searching Cochrane, PubMed, and Scopus for peer-reviewed studies published from 1995 to 2024 using the keywords head and neck cancer, readability, health literacy, and related synonyms. Full-text studies in English that evaluated readability and/or HL measures were included. Readability assessments included the Flesch-Kincaid Grade Level (FKGL grade, 0-20, with higher grades indicating greater reading difficulty) and Flesch Reading Ease (FRE score, 1-100, with higher scores indicating easier readability), among others. Reviews, conference materials, opinion letters, and guidelines were excluded. Study quality was assessed using the Appraisal Tool for Cross-Sectional Studies.

Findings

Of the 3235 studies identified, 17 studies assessing the readability of 1124 HNC PEMs produced by professional societies, hospitals, and others were included. The mean FKGL grade ranged from 8.8 to 14.8; none of the studies reported a mean FKGL of grade 6 or lower. Eight studies assessed HL and found inadequate HL prevalence ranging from 11.9% to 47.0%.

Conclusions and Relevance

These findings indicate that more than one-third of patients with HNC demonstrate inadequate HL, yet none of the PEMs assessed were developed for a sixth grade or lower reading level, as recommended by the American Medical Association. This incongruence highlights the need to address the readability of HNC PEMs to improve patient understanding of the disease and to mitigate potential barriers to shared decision-making for patients with HNC. It is crucial to acknowledge the responsibility of health care professionals to produce and promote more effective PEMs to dismantle the potentially preventable literacy barriers.

Human papilloma virus (HPV)-related information acquisition and seeking behavior among infected women: A single center cross-sectional survey in Shanghai, China

Lacking of adequate knowledge is an obstacle to effective prevention of cervical cancer, yet factors that affect the information acquisition and seeking behavior as well as the information communication process are not well studied. We assessed information acquisition and seeking behavior, as well as perceived barriers of doctor-patient communication regarding human papilloma virus (HPV)-related information of infected women. Among 437 participants, 405 (93%) expressed demands for HPV-related information, while only a small proportion (100/437, 22.9%) actively sought information and felt obstacles comprehending. Web-based channels were most frequently utilized and medical personnel were the most trusted information source. Patients' satisfaction was significantly correlated with doctor's patience (r = 0.581, p < 0.001) and emotional caring (r = 0.555, p < 0.001). Compared to patients not actively seeking information, those actively seeking information were more likely to be single (p = 0.005), had higher education (p = 0.009) and monthly individual-level income (p = 0.023), and was more likely to undergo regular cervical cancer screening (p = 0.003), and were already or willing to be vaccinated (p = 0.008). The actively seeking information group also achieved higher scores in HPV knowledge test (p = 0.007). Public health interventions targeting HPV-infected women using specifically designed educational materials may influence information seeking behavior, increase HPV literacy and knowledge, which could potentially increase HPV vaccine uptake and cervical cancer screening rate.

Assessing the Readability of Online Patient Education Materials in Obstetrics and Gynecology Using Traditional Measures: Comparative Analysis and Limitations

BACKGROUND

Patient education materials (PEMs) can be vital sources of information for the general population. However, despite American Medical Association (AMA) and National Institutes of Health (NIH) recommendations to make PEMs easier to read for patients with low health literacy, they often do not adhere to these recommendations. The readability of online PEMs in the obstetrics and gynecology (OB/GYN) field, in particular, has not been thoroughly investigated.

OBJECTIVE

The study sampled online OB/GYN PEMs and aimed to examine (1) agreeability across traditional readability measures (TRMs), (2) adherence of online PEMs to AMA and NIH recommendations, and (3) whether the readability level of online PEMs varied by web-based source and medical topic. This study is not a scoping review, rather, it focused on scoring the readability of OB/GYN PEMs using the traditional measures to add empirical evidence to the literature.

METHODS

A total of 1576 online OB/GYN PEMs were collected via 3 major search engines. In total 93 were excluded due to shorter content (less than 100 words), yielding 1483 PEMs for analysis. Each PEM was scored by 4 TRMs, including Flesch-Kincaid grade level, Gunning fog index, Simple Measure of Gobbledygook, and the Dale-Chall. The PEMs were categorized based on publication source and medical topic by 2 research team members. The readability scores of the categories were compared statistically.

RESULTS

Results indicated that the 4 TRMs did not agree with each other, leading to the use of an averaged readability (composite) score for comparison. The composite scores across all online PEMs were not normally distributed and had a median at the 11th grade. Governmental PEMs were the easiest to read amongst source categorizations and PEMs about menstruation were the most difficult to read. However, the differences in the readability scores among the sources and the topics were small.

CONCLUSIONS

This study found that online OB/GYN PEMs did not meet the AMA and NIH readability recommendations and would be difficult to read and comprehend for patients with low health literacy. Both findings connected well to the literature. This study highlights the need to improve the readability of OB/GYN PEMs to help patients make informed decisions. Research has been done to create more sophisticated readability measures for medical and health documents. Once validated, these tools need to be used by web-based content creators of health education materials.

Contact investigations for antibiotic-resistant bacteria: a mixed-methods study of patients' comprehension of and compliance with self-sampling requests post-discharge

BACKGROUND

Contact investigation is an important tool to identify unrecognized patients who are colonized with antibiotic-resistant bacteria. Many Dutch hospitals include already discharged contact patients by sending them a self-sampling request at home, incl. an information letter and sampling materials. Each hospital composes these information letters on their own initiative, however, whether discharged patients comprehend and comply with these requests remains unclear. Therefore, the aim was to provide insight into patients' comprehension of and self-reported compliance with self-sampling requests post-discharge.

METHODS

This mixed-methods study was performed in eight Dutch hospitals. First, the Common European Framework of Reference (CEFR) language level of self-sampling request letters was established. Second, a questionnaire about patients' comprehension of the letter, self-reported compliance, and reasons for compliance or non-compliance were sent to patients that received such a request in 2018/2019. Finally, a random selection of questionnaire respondents was interviewed between January and March 2020 to gain additional insights.

RESULTS

CEFR levels of 15 letters were established. Four letters were assigned level B1, four letters B1-B2, and seven letters B2. The majority of patients reported good comprehension of the letter they had received. Conversely, some respondents indicated that information about the bacterium (18.4%), the way in which results would be communicated (18.1%), and the self-sampling instructions (9.7%) were (partially) unclear. Furthermore, self-reported compliance was high (88.8%). Reasons to comply were personal health (84.3%), the health of others (71.9%), and general patient safety (96.1%). Compliant patients appeared to have a need for confirmation, wanted to protect family and/or friends, and felt they were providing the hospital the ability to control the transmission of antibiotic-resistant bacteria. Although a limited number of non-compliant patients responded to the questionnaire, it seemed that more patients did not comply with self-sampling requests when they received a letter in a higher CEFR-level (B2) compared to a lower CEFR-level (< B2) (9.8% vs. 2.5%, P = 0.049).

CONCLUSIONS

This study showed an overall good comprehension of and high self-reported compliance with self-sampling requests post-discharge. Providing balanced information in self-sampling request letters has the potential to reduce patient's ambiguity and concerns, and can cause increased compliance with self-sampling requests.

Communications Is Time for Care: An Italian Monocentric Survey on Human Papillomavirus (HPV) Risk Information as Part of Cervical Cancer Screening

Human papilloma virus (HPV) infection could be considered a social disease, both for its high incidence, especially in younger subjects, and for the risk of neoplastic evolution linked to viral infection. Therefore, the National Health System, in collaboration with the state, must help women to understand the oncological risk of HPV and suitable methods of prevention. We conducted an Italian monocentric survey on HPV risk information as part of cervical cancer screening. An anonymous questionnaire was administered to 200 women with high-risk positive HPV and low-grade cervical lesions during second-level cervical cancer screening at the Gynecology and Obstetrics Unit of the "San Paolo" Hospital. From this survey, the need to improve communication for patients has emerged, as currently it is not exhaustive. In response to this need, organizational changes have been implemented to centralize the moment of counseling in the second levels of screening and to improve the training of health workers in level I as well as family doctors. In addition, psychological support was also proposed to patients who requested it, as was the dissemination of material such as that produced by GISCI (Italian Cervico-Carcinoma Screening Group) and updated in May 2018, which provides 100 answers to questions on HPV in order to achieve effective and comprehensive communication. This investigation requires further development, and the expansion of this investigation to the multicenter level is already underway. Therefore, this survey will represent a cornerstone for further discussion on the topic considering the necessity of appropriate communication in the oncological context.
