Suitability and readability of consumer medical information accompanying prescription medication samples

Comprehension and usefulness of Spanish language health information about depression treatment

US Latine adults who prefer the Spanish language for healthcare encounter communication have high risk of health disparitiesm in part from low organizational health literacy, mental health stigma and discrimination. Organizational health literacy includes the provision of culturally responsive, language concordant health information, which supports good comprehension and usefulness and could mitigate some health disparities. We conducted a pilot study to assess commonly provided patient health information handouts about depression treatment and antidepressant consumer medication information sheets. Thirty Latine adults with a Spanish language preference and a history of depression and antidepressant use participated in one phone interview. Descriptive statistics and thematic analysis were used to assess comprehension and usefulness of selected sections extracted verbatim from these documents. Overall, 83% (n = 25) participants reported that all sections were easy to understand, and 97% (n = 29) said that they were useful. Yet, responses to open-ended questions for 53% (n = 16) of participants revealed 'confusing' terminology in at least one section, and 10% (n = 3) expressed concerns about or misunderstood an idiomatic phrase as reinforcing mental health stigma. The seriousness of the organizational health literacy-based issues identified in this and previous studies require that government and health service organizations make necessary and timely revisions to address them.

Effects of additional context information in prescription drug information sheets on comprehension and risk and efficacy perceptions

Objective

To determine how additional explanatory text (context) about drug side effects in a patient medication information handout affected comprehension and perceptions of risk and efficacy.

Methods

We conducted an online experiment with a national sample of 1,119 U.S. adults with rheumatoid arthritis and related conditions, sampled through random-digit dialing, address-based sampling, and online ads. We randomized participants to receive one of several versions of a patient information handout for a fictitious drug, either with or without additional context, then measured comprehension and other outcomes.

Results

Additional qualitative context about warnings and side effects resulted in lower comprehension of side effect information, but not information about uses of the drug or warnings. The effect of additional context on risk perceptions depended on whether the medication handout was delivered online or through the mail. Those who received a hardcopy of the handout with additional context had higher perceived risk of side effects than those who saw the version without additional context.

Conclusion

More clarifying information is not always better and may lead to cognitive overload, inhibiting comprehension.

Practice implications

Additional research should further explore effects of context in online vs. hard-copy formats before practice implications can be determined.

Evolutionary Overview of Consumer Health Informatics: Bibliometric Study on the Web of Science from 1999 to 2019

BACKGROUND

Consumer health informatics (CHI) originated in the 1990s. With the rapid development of computer and information technology for health decision making, an increasing number of consumers have obtained health-related information through the internet, and CHI has also attracted the attention of an increasing number of scholars.

OBJECTIVE

The aim of this study was to analyze the research themes and evolution characteristics of different study periods and to discuss the dynamic evolution path and research theme rules in a time-series framework from the perspective of a strategy map and a data flow in CHI.

METHODS

The Web of Science core collection database of the Institute for Scientific Information was used as the data source to retrieve relevant articles in the field of CHI. SciMAT was used to preprocess the literature data and construct the overlapping map, evolution map, strategic diagram, and cluster network characterized by keywords. Besides, a bibliometric analysis of the general characteristics, the evolutionary characteristics of the theme, and the evolutionary path of the theme was conducted.

RESULTS

A total of 986 articles were obtained after the retrieval, and 931 articles met the document-type requirement. In the past 21 years, the number of articles increased every year, with a remarkable growth after 2015. The research content in 4 different study periods formed the following 38 themes: patient education, medicine, needs, and bibliographic database in the 1999-2003 study period; world wide web, patient education, eHealth, patients, medication, terminology, behavior, technology, and disease in the 2004-2008 study period; websites, information seeking, physicians, attitudes, technology, risk, food labeling, patient, strategies, patient education, and eHealth in the 2009-2014 study period; and electronic medical records, health information seeking, attitudes, health communication, breast cancer, health literacy, technology, natural language processing, user-centered design, pharmacy, academic libraries, costs, internet utilization, and online health information in the 2015-2019 study period. Besides, these themes formed 10 evolution paths in 3 research directions: patient education and intervention, consumer demand attitude and behavior, and internet information technology application.

CONCLUSIONS

Averaging 93 publications every year since 2015, CHI research is in a rapid growth period. The research themes mainly focus on patient education, health information needs, health information search behavior, health behavior intervention, health literacy, health information technology, eHealth, and other aspects. Patient education and intervention research, consumer demand, attitude, and behavior research comprise the main theme evolution path, whose evolution process has been relatively stable. This evolution path will continue to become the research hotspot in this field. Research on the internet and information technology application is a secondary theme evolution path with development potential.

Patients' Experiences and Perspectives of Receiving Written Medicine Information About Medicines: A Qualitative Study

PURPOSE

Written medicine information informs patients about the benefits and risks of medicines and supports their safe and effective use. In Thailand, patient information leaflets (PILs) are not obligatory and therefore not routinely supplied. This study aimed to explore the experiences and information needs of patients, their views on PILs and the likely impact of PILs on their knowledge, perceptions and behaviors towards medicines. These factors are important to establish the value of PILs.

METHODS

Semi-structured interviews with outpatients who received simvastatin or atorvastatin were conducted exploring their experiences of receiving medicine information, their views on the utility of and need for PILs, the impact of PILs on their behaviors, and recommendations for how PILs could be improved. All interviews were audio-recorded, transcribed verbatim, and analyzed using a framework approach.

RESULTS

Thirty interviews were conducted from which four themes emerged: experience of receiving medicine information, views of package inserts and PILs, impact of PILs on knowledge, perceptions and behaviors, and patients' need for medicine information. Most participants received verbal information from healthcare professionals, as well as written information. Verbal information was perceived as being particularly useful to inform about changes to medicine regimens or the long-term adverse effects of medicines. Patients perceived that the PILs had influenced their knowledge about medicines, and also their behaviors including safety awareness, adherence, and engagement with healthcare professionals. Participants suggested that the information in electronic format could provide an additional resource. Some changes to improve the content and general format of the PIL were identified.

CONCLUSION

PILs are perceived as useful by patients and met their information needs, although they were viewed as an adjunct to verbal advice provided by healthcare professionals. PILs influenced patients' medicine taking behaviors and encouraged sharing of information with their physicians.

Patient literacy and awareness of medicine safety

Objective

To assess public understanding of medicine safety, approach to risks and preferences in accessing safety information.

Methods

Qualitative data were obtained from an online survey (n = 1079) covering four major themes around side effects and risks of medicines: willingness to accept side effects of medications, information seeking, sufficiency of information and understanding pharmacovigilance process. Comparisons were made for age, gender and social/financial status.

Key findings

Most respondents acknowledged medications were associated with side effects. If side effects were experienced, most (73%) would seek advice from their doctor or pharmacist. Four in 10 respondents felt doctors and pharmacists do not provide sufficient information about medications, even though many (47%) relied on their doctor to provide this. Although 51% felt that pharmaceutical companies were already providing enough information to patients, 95% responded that extra effort could still be made. Two-thirds of the respondents felt it was the companies’ responsibility to educate doctors and pharmacists so they could pass the information on, even though younger respondents preferred direct communication to patients compared to older respondents (<24 years, 36% versus >65 years, 10%; P < 0.001). Men were more willing to accept risks, while women were more likely to seek information about their medicines. Understanding of the role of pharmaceutical companies and government in maintaining the safety of medicines was generally poor.

Conclusions

There is an ongoing need for consumer education regarding medicine safety. Doctors and pharmacists remain the more trusted source of information. Pharmaceutical companies play an important role in ensuring such information is both accessible and accurate.

Development of Comprehensible Prescription Label Instructions: A Study Protocol for a Mixed-Methods Approach

Introduction

Patients receive information about their medication from different sources, including prescription labels. These labels are physically attached to each package dispensed to patients and contain the most important instructions on how to use the medication correctly. However, many patients experience difficulties in understanding and applying the instructions on these labels correctly, especially patients with limited health literacy. The aim of this study is to investigate the comprehensibility of prescription label instructions among patients with adequate and limited health literacy skills, and to implement improvements in primary health care.

Methods

We used a mixed-methods approach, which consisted of four phases. Phase 1 (desk research) was divided into a systematic literature review on the comprehensibility of prescription label instructions (1a) and a content analysis of the textual elements in Dutch prescription label instructions (1b). In phase 2 (patient studies), semi-structured interviews were conducted to investigate the comprehensibility of seven prescription labels among patients with different health literacy skills (2a), and a quantitative study in which the comprehensibility of six optimized prescription labels was compared among patients with different health literacy skills (2b). Patient studies were conducted in eight Dutch pharmacies. In phase 3 optimized prescription label instructions were implemented in national medication databases which has been supported by a guideline (3a), and education of pharmacy workers (3b). Phase 4 consists of evaluating the optimized prescription label instructions by experiences from patients and pharmacists.

Anticipated Results

This mixed-methods approach will result in scientific publications of the individual studies, and a guideline on how to compose comprehensible prescription label instructions to be put on medication packages. Optimized prescription label instructions will be implemented in national medication databases.

Discussion

This protocol describes a mixed-method research to compose and implement comprehensible prescription label instructions and will lead to knowledge about the comprehensibility of textual elements in these labels, with specific attention for patients with limited health literacy. Implementation of optimized prescription label instructions will lead to a better understanding of them, which may contribute to improved medication adherence. A limitation is that non-textual aspects of prescription labels are not investigated.

The extent and effects of patient involvement in pictogram design for written drug information: a short systematic review

This short review provides insight into the extent and effectiveness of patient involvement in the design and evaluation of pictograms to support patient drug information. Pubmed, CINAHL, Cochrane Library, Embase, PsycINFO, Academic Search Premier and Web of Science were searched systematically; the 73 included articles were evaluated with the MMAT. We see that, usually, non-patient end-users are involved in the design of pharmaceutical pictograms - patients are more commonly involved in the final evaluation of pictogram success. Repeated involvement of (non-)patients aids the design of effective pharmaceutical pictograms, although there is limited evidence for such effects on patient perception of drug information or health behaviour.

Pharma Websites and "Professionals-Only" Information: The Implications for Patient Trust and Autonomy

Background

Access to information is critical to a patient’s valid exercise of autonomy. One increasingly important source of medical information is the Internet. Individuals often turn to drug company (“pharma”) websites to look for drug information.

Objective

The objective of this study was to determine whether there is information on pharma websites that is embargoed: Is there information that is hidden from the patient unless she attests to being a health care provider? We discuss the implications of our findings for health care ethics.

Methods

We reviewed a convenience sample of 40 pharma websites for “professionals-only” areas and determined whether access to those areas was restricted, requiring attestation that the user is a health care professional in the United States.

Results

Of the 40 websites reviewed, 38 had information that was labeled for health care professionals-only. Of these, 24 required the user to certify their status as a health care provider before they were able to access this “hidden” information.

Conclusions

Many pharma websites include information in a “professionals-only” section. Of these, the majority require attestation that the user is a health care professional before they can access the information. This leaves patients with two bad choices: (1) not accessing the information or (2) lying about being a health care professional. Both of these outcomes are unacceptable. In the first instance, the patient’s access to information is limited, potentially impairing their health and their ability to make reasonable and well-informed decisions. In the second instance, they may be induced to lie in a medical setting. “Teaching” patients to lie may have adverse consequences for the provider-patient relationship.

Pharmaceutical pictograms for low-literate patients: Understanding, risk of false confidence, and evidence-based design strategies

OBJECTIVE

This study aims to (1) evaluate ten pharmaceutical pictograms for low-literate patients on understandability, (2) assess the risk of false confidence in understanding, and (3) identify how the design can be improved to increase understandability.

METHODS

Interviews were conducted with n=197 pharmacy visitors in the Netherlands. Additional qualitative discussions were held with n=30 adequately and n=25 low-literate participants (assessed with REALM-D). Qualitative data were analysed using the Thematic Framework approach.

RESULTS

Half of the pictograms reached 67% understanding (31.0%-98.5%); two did in the low-literate group. Three pictograms showed a risk for false confidence. Pictograms appeared to be most effective when people were familiar with their visual elements and messages.

CONCLUSION

Low-literate people have more difficulty understanding pictograms than people with adequate literacy. While the risk of false confidence is low, for critical safety information, 67% understanding might not be sufficient. Design strategies for pharmaceutical pictograms should focus on familiarity, simplicity, and showing the intake and effect of medicine.

PRACTICE IMPLICATIONS

Health professionals should go over the meaning of pictograms when providing drug information to patients to increase patients' familiarity with the message and to ensure that all pictograms are sufficiently understood.

Readability Formulas and User Perceptions of Electronic Health Records Difficulty: A Corpus Study

Background

Electronic health records (EHRs) are a rich resource for developing applications to engage patients and foster patient activation, thus holding a strong potential to enhance patient-centered care. Studies have shown that providing patients with access to their own EHR notes may improve the understanding of their own clinical conditions and treatments, leading to improved health care outcomes. However, the highly technical language in EHR notes impedes patients’ comprehension. Numerous studies have evaluated the difficulty of health-related text using readability formulas such as Flesch-Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG), and Gunning-Fog Index (GFI). They conclude that the materials are often written at a grade level higher than common recommendations.

Objective

The objective of our study was to explore the relationship between the aforementioned readability formulas and the laypeople’s perceived difficulty on 2 genres of text: general health information and EHR notes. We also validated the formulas’ appropriateness and generalizability on predicting difficulty levels of highly complex technical documents.

Methods

We collected 140 Wikipedia articles on diabetes and 242 EHR notes with diabetes International Classification of Diseases, Ninth Revision code. We recruited 15 Amazon Mechanical Turk (AMT) users to rate difficulty levels of the documents. Correlations between laypeople’s perceived difficulty levels and readability formula scores were measured, and their difference was tested. We also compared word usage and the impact of medical concepts of the 2 genres of text.

Results

The distributions of both readability formulas’ scores (P<.001) and laypeople’s perceptions (P=.002) on the 2 genres were different. Correlations of readability predictions and laypeople’s perceptions were weak. Furthermore, despite being graded at similar levels, documents of different genres were still perceived with different difficulty (P<.001). Word usage in the 2 related genres still differed significantly (P<.001).

Conclusions

Our findings suggested that the readability formulas’ predictions did not align with perceived difficulty in either text genre. The widely used readability formulas were highly correlated with each other but did not show adequate correlation with readers’ perceived difficulty. Therefore, they were not appropriate to assess the readability of EHR notes.

An efficacy trial of an electronic health record-based strategy to inform patients on safe medication use: The role of written and spoken communication

OBJECTIVE

We tested the feasibility and efficacy of an electronic health record (EHR) strategy that automated the delivery of print medication information at the time of prescribing.

METHODS

Patients (N=141) receiving a new prescription at one internal medicine clinic were recruited into a 2-arm physician-randomized study. We leveraged an EHR platform to automatically deliver 1-page educational 'MedSheets' to patients after medical encounters. We also assessed if physicians counseled patients via patient self-report immediately following visits. Patients' understanding was objectively measured via phone interview.

RESULTS

122 patients completed the trial. Most intervention patients (70%) reported receiving MedSheets. Patients reported physicians frequently counseled on indication and directions for use, but less often for risks. In multivariable analysis, written information (OR 2.78, 95% CI 1.10-7.04) and physician counseling (OR 2.95, 95% CI 1.26-6.91) were independently associated with patient understanding of risk information. Receiving both was most beneficial; 87% of those receiving counseling and MedSheets correctly recalled medication risks compared to 40% receiving neither.

CONCLUSION

An EHR can be a reliable means to deliver tangible, print medication education to patients, but cannot replace the salience of physician-patient communication.

PRACTICE IMPLICATIONS

Offering both written and spoken modalities produced a synergistic effect for informing patients.

Extending FDA guidance to include consumer medication information (CMI) delivery on mobile devices

This paper describes the current state of consumer-focused mobile health application use and the current U.S. Food and Drug Administration (FDA) guidance on the distribution of consumer medication information (CMI), and discusses recommendations and considerations for the FDA to expand CMI guidance to include CMI in mobile applications. Smartphone-based health interventions have been linked to increased medication adherence and improved health outcomes. Trends in smartphone ownership present opportunities to more effectively communicate and disseminate medication information; however, current FDA guidance for CMI does not outline how to effectively communicate CMI on a mobile platform, particularly in regards to user-centered design and information sourcing. As evidence supporting the potential effectiveness of mobile communication in health care continues to increase, CMI developers, regulating entities, and researchers should take note. Although mobile-based CMI offers an innovative mechanism to deliver medication information, caution should be exercised. Specifically, considerations for developing mobile CMI include consumers' digital literacy, user experience (e.g., usability), and the quality and accuracy of new widely used sources of information (e.g., crowd-sourced reviews and ratings). Recommended changes to FDA guidance for CMI include altering the language about scientific accuracy to address more novel methods of information gathering (e.g., anecdotal experiences and Google Consumer Surveys) and including guidance for usability testing of mobile health applications.

Readability of medicinal package leaflets: a systematic review

OBJECTIVE

To review studies on the readability of package leaflets of medicinal products for human use.

METHODS

We conducted a systematic literature review between 2008 and 2013 using the keywords “Readability and Package Leaflet” and “Readability and Package Insert” in the academic search engine Biblioteca do Conhecimento Online, comprising different bibliographic resources/databases. The preferred reporting items for systematic reviews and meta-analyses criteria were applied to prepare the draft of the report. Quantitative and qualitative original studies were included. Opinion or review studies not written in English, Portuguese, Italian, French, or Spanish were excluded.

RESULTS

We identified 202 studies, of which 180 were excluded and 22 were enrolled [two enrolling healthcare professionals, 10 enrolling other type of participants (including patients), three focused on adverse reactions, and 7 descriptive studies]. The package leaflets presented various readability problems, such as complex and difficult to understand texts, small font size, or few illustrations. The main methods to assess the readability of the package leaflet were usability tests or legibility formulae. Limitations with these methods included reduced number of participants; lack of readability formulas specifically validated for specific languages (e.g., Portuguese); and absence of an assessment on patients literacy, health knowledge, cognitive skills, levels of satisfaction, and opinions.

CONCLUSIONS

Overall, the package leaflets presented various readability problems. In this review, some methodological limitations were identified, including the participation of a limited number of patients and healthcare professionals, the absence of prior assessments of participant literacy, humor or sense of satisfaction, or the predominance of studies not based on role-plays about the use of medicines. These limitations should be avoided in future studies and be considered when interpreting the results.

Patients' preferences for visuals: differences in the preferred level of detail, type of background and type of frame of icons depicting organs between literate and low-literate people

OBJECTIVE

To evaluate icons of organs with systematic variations in design to provide directions for the development of pictograms that support patient leaflets targeted at a low-literate audience.

METHODS

In interview questionnaires, 191 pharmacy visitors (IJsselstein, The Netherlands), indicated for four organs in which image the organ was represented most clearly. The icons vary in level of detail of the depicted organ, in the organs that are shown in the background, and in how much of the body is shown as frame. Participants' literacy was determined through the Dutch Rapid Estimate of Adult Literacy in Medicine (REALM-D).

RESULTS

For the three internal organs, the intestines, lungs and kidneys, low-literate participants were more likely than literate participants to opt for less context in the form of the frame of the body.

CONCLUSION

When the meaning of the visual is given, low-literate people prefer organ icons with less context of the body over a depiction of the whole body.

PRACTICE IMPLICATIONS

Since literate and low-literate people differ in perceptual preferences, continued involvement of people with limited literacy skills in the design process is essential to target the visuals to their needs.

Polysubstance abuse: alcohol, opioids and benzodiazepines require coordinated engagement by society, patients, and physicians

The Centers for Disease Control and Prevention (CDC) has published significant data trends related to substance abuse involving opioid pain relievers (OPR), benzodiazepines and alcohol in the United States. The CDC describes opioid misuse and abuse as an epidemic, with the use of OPR surpassing that of illicit drugs. Alcohol has also been a persistent problem and is associated with a number of emergency department visits and deaths independent of other substances. The use of these drugs in combination creates an additive effect with increased central nervous system suppression and a heightened risk of an overdose. We present a summary of the findings from the Morbidity and Mortality Weekly Report (MMWR) with commentary on strategies to combat prescription drug and alcohol abuse.

Characterizing the relationship between free drug samples and prescription patterns for acne vulgaris and rosacea

IMPORTANCE

Describing the relationship between the availability of free prescription drug samples and dermatologists' prescribing patterns on a national scale can help inform policy guidelines on the use of free samples in a physician's office.

OBJECTIVES

To investigate the relationships between free drug samples and dermatologists' local and national prescribing patterns and between the availability of free drug samples and prescription costs.

DESIGN, SETTING, AND PARTICIPANTS

Cross-sectional study investigating prescribing practices for acne, a common dermatologic condition for which free samples are often available. The settings were, first, the offices of nationally representative dermatologists from the National Disease and Therapeutic Index (an IMS Health Incorporated database) and, second, an academic medical center clinic without samples. Participants were ambulatory patients who received a prescription from a dermatologist for a primary initial diagnosis of acne vulgaris or rosacea in 2010.

MAIN OUTCOMES AND MEASURES

National trends in dermatologist prescribing patterns, the degree of correlation between the availability of free samples and the prescribing of brand-name medications, and the mean cost of acne medications prescribed per office visit nationally and at an academic medical center without samples.

RESULTS

On a national level, the provision of samples with a prescription by dermatologists has been increasing over time, and this increase is correlated (r = 0.92) with the use of the branded generic drugs promoted by these samples. Branded and branded generic drugs comprised most of the prescriptions written nationally (79%), while they represented only 17% at an academic medical center clinic without samples. Because of the increased use of branded and branded generic drugs, the national mean total retail cost of prescriptions at an office visit for acne was conservatively estimated to be 2 times higher (approximately $465 nationally vs $200 at an academic medical center without samples).

CONCLUSIONS AND RELEVANCE

Free drug samples can alter the prescribing habits of physicians away from the use of less expensive generic medications. The benefits of free samples in dermatology must be weighed against potential negative effects on prescribing behavior and prescription costs.

A content analysis of visual cancer information: prevalence and use of photographs and illustrations in printed health materials

Researchers and practitioners have an increasing interest in visual components of health information and health communication messages. This study contributes to this evolving body of research by providing an account of the visual images and information featured in printed cancer communication materials. Using content analysis, 147 pamphlets and 858 images were examined to determine how frequently images are used in printed materials, what types of images are used, what information is conveyed visually, and whether or not current recommendations for the inclusion of visual content were being followed. Although visual messages were found to be common in printed health materials, existing recommendations about the inclusion of visual content were only partially followed. Results are discussed in terms of how relevant theoretical frameworks in the areas of behavior change and visual persuasion seem to be used in these materials, as well as how more theory-oriented research is necessary in visual messaging efforts.

Development and validation of the Patient Opioid Education Measure

BACKGROUND

Although there are screening tools to aid clinicians in assessing the risk of opioid misuse, an instrument to assess opioid-related knowledge is not currently available. The purpose of this study was to develop a content-valid, understandable, readable, and reliable Patient Opioid Education Measure (POEM).

METHODS

Using concept mapping, clinicians caring for patients with chronic pain participated in brainstorming, sorting, and rating need-to-know information for patients prescribed opioids. Concept mapping analyses identified seven clusters addressing knowledge and expectations associated with opioid use, including medicolegal issues, prescribing policies, safe use and handling, expected outcomes, side effects, pharmacology, and warnings.

RESULTS

The 49-item POEM was verbally administered to 83 patients (average age 51.3 ± 9.8 years, 77.1% female, 47.1% African American) taking opioids for chronic nonmalignant pain. Patients averaged in total 63.9% ± 14.3% (range 23%-91%) correct responses on the POEM. The POEM demonstrated substantial test-retest reliability (interclass correlation coefficient 0.87). The POEM had a mean readability Lexile (L) score of 805.9 ± 257.3 L (equivalent to approximately a US fifth grade reading level), with individual items ranging from 280 L to 1370 L.

CONCLUSION

The POEM shows promise for rapidly identifying patients' opioid-related knowledge gaps and expectations. Correcting misunderstandings and gaps could result in safer use of opioids in a clinical care setting.

Health literacy and the readability of written information for hormone therapies

INTRODUCTION

Health education and counseling are important elements of the care provided by clinicians. Counseling efforts may involve helping women to understand their options for symptom management related to various reproductive life transitions. In light of this, the need for information during the menopausal transition is critical for assisting women with their health care decisions. Yet the Institute of Medicine estimates that approximately half the adult population in the United States has difficulty understanding and using health information. The US Food and Drug Administration (FDA) mandates the distribution of written information for estrogen-containing products; however, the readability of information for these pharmaceutical products has not been widely studied. To address this gap, this study examined the readability of written information for FDA-approved prescription menopausal hormone therapies (N = 31).

METHODS

Readability of the written information about hormone therapies from 31 hormone therapy products was assessed using the Flesch Reading Ease and Flesch-Kincaid Grade Level formulas.

RESULTS

The reading level ranged from 6.70 to 12.30, with an average grade level of 9.33 (ninth-grade reading level). All but one of the hormone therapy products evaluated in this study exceeded the recommended sixth-grade reading level for written health information. In addition, only 48% of the written information instructions in the study sample (n = 15) included illustrations.

DISCUSSION

Assessment of written information about menopausal hormone therapies showed that the majority of the materials are written at a high reading level. These findings have implications for health literacy and counseling efforts when helping women to understand their options for menopausal symptom management. Midwives, nurses, and other health care providers may need to supplement written information with additional consumer-friendly written information, utilize illustrations, and use verbal instructions more frequently to help support women in evaluating their treatment options.

Readability of menopause web sites: a cross-sectional study

More women are frequently referring to the Internet for health information, yet the readability of information about menopause on the Internet has not been widely studied. To address this gap, this study examined the readability of information about menopause on 25 Internet Web sites. Findings included that information on the Web sites had a reading level higher than the recommended sixth-grade level, and culturally appropriate health information was lacking. Health educators and practitioners are in a pivotal role to help women understand information useful for healthcare decisions. Several criteria are discussed to help practitioners evaluate Web sites.

Don't let the flu catch you: agency assignment in printed educational materials about the H1N1 influenza virus

In English and in other languages, the agency for viral transmission can be grammatically assigned to people (e.g., Thousands may contract H1N1) or to the virus itself (e.g., H1N1 may infect thousands). These assignment options shape different conceptions of transmission as attributable either to social contact within one's control or to pursuit of an active predator. The authors tested the effect of agency assignment and agentic images on young adults' (N = 246) reactions to educational materials about H1N1 influenza. The authors hypothesized that assigning agency to the virus would heighten perceived severity and personal susceptibility relative to human agency assignment. Results were consistent with this hypothesis, indicating that virus agency increased perceptions of severity, personal susceptibility, and reported intentions to seek vaccination relative to human agency. The image manipulation did not directly affect these factors. The findings suggest that strategic agency assignment can improve the effectiveness of educational materials about influenza and other health threats.

Tailored DVDs: a novel strategy for educating racially and ethnically diverse older adults about their medicines

INTRODUCTION

The availability of comprehensive and accurate medication history information in electronic medical records and through electronic prescribing provides the opportunity to create tailored interventions based on individuals' particular medication information needs. To meet the challenges of providing medication information to low-literate English and Spanish speaking older adults, we sought to create individualized, culturally and linguistically inclusive medication education materials for older adults from diverse backgrounds.

METHODS

We used a mixed-method design including a systematic review, analysis of existing data, a telephone survey (n=326), and exploratory focus groups stratified by race/ethnicity and language spoken (11 focus groups; n=106) to identify what information about medications older adults need, want to learn, and in what format. We evaluated reactions to three DVDs at low-income senior community centers (2 focus groups; n=16).

RESULTS

Exploratory focus groups provided insights on areas for improvement in patient-provider communication, and suggested use of vignettes and testimonials. Upon viewing, participants could relate to the testimonials in which actors portrayed people who have problems with their medications and were interested in the medication advice presented, especially when it was presented by a healthcare professional.

DISCUSSION

Tailored medication education materials in English and Spanish DVD and print material format are suitable for low-literate audiences, acceptable to older adults, and feasible to implement using health IT. Virtually all households in the United States have a television, with most having a DVD player. DVD segments can be used in Internet links, physician office-based television, and consumer health IT applications.

Randomized controlled trial evaluating pictogram augmentation of HIV medication information

BACKGROUND

Antiretroviral therapy for the management of HIV typically requires the chronic use of 3 or more medications. As such, patients with HIV are required to manage complex dosing schedules and are at risk of multiple potential adverse effects. The use of pictograms on medication vials as a means of improving patients' understanding of medication information has been shown to positively influence understanding and adherence compared to those using text alone.

OBJECTIVE

To determine whether pictograms (Pharmaglyph) increase patient recall of targeted information associated with HIV medications and whether patients can interpret the intended meaning of pictograms that they had not seen previously.

METHODS

A randomized, controlled trial was conducted in HIV-positive patients aged 19 years or older who were receiving a new prescription for an antiretroviral medication from the ambulatory pharmacy at St. Paul's Hospital in Vancouver, British Columbia, Canada. Participants were randomized to receive either pictogram-enhanced medication information or standard counseling. At the first follow-up visit, each patient's recall of the medication information was evaluated, and differences between groups were compared.

RESULTS

Eighty-two subjects were randomized, 40 to the intervention group and 42 to the control arm. The mean (SD) number of HIV medications was nearly equal between the intervention and control groups: 3.0 (1.5) and 3.1 (1.4), respectively. After a mean of 34 days, 33 patients in the intervention arm and 39 in the control arm completed the study. The majority (88%) of the targeted pieces of information in the intervention group were correctly identified at follow-up, compared to only 2% in the control group (Fisher exact test; p < 0.0001).

CONCLUSIONS

Pictograms improve the recall of targeted medication information among patients receiving antiretroviral therapy for HIV management; however, this appears to be dependent on the fact that these patients received a verbal explanation of each pictogram prior to use.

ABOP, the automatic patient information leaflet optimizer: evaluation of a tool in development

OBJECTIVE

We developed a semi-automated leaflet optimizer (ABOP) to improve the readability of Dutch patient information leaflets (PILs). Our aim was to assess whether or not revisions made with ABOP have an effect on traceability and comprehension of PIL information.

METHODS

Two leaflets (one for oxazepam and one for tetracycline) were revised with the ABOP tool and both the original versions and ABOP versions were tested for readability, according to the EC guideline.

RESULTS

The ABOP version for oxazepam (p<.0001) scored significantly better than its original counterpart in readability tests. Although the results showed that the ABOP version of the tetracycline antibiotic outperformed the original version the difference in scores was not statistically significant. Terminology improvements had the greatest effect on information retrieval and comprehension. Improvements to instructions and warnings did not affect retrieval and comprehension scores. Overall improvements did not ensure full compliance with EC requirements, but results are not far off.

CONCLUSION

This study shows that even though ABOP does not solve all text quality issues, it does largely prepare a PIL for readability testing.

PRACTICE IMPLICATIONS

Using ABOP as a revision tool for PILs can optimize PIL quality and hence reduce readability testing time and costs.

Tools used to evaluate written medicine and health information: document and user perspectives

This study aims to identify and review tools used to evaluate consumer-oriented written medicine (WMI) and health (WHI) information from a document and user perspective. Articles that met the following inclusion criteria were reviewed: studies evaluating readability, presentation, suitability, quality of WMI/WHI. A total of 152 articles were identified, of which 64 satisfied the inclusion criteria. Fifty-nine original studies used evaluation tools and 5 reviewed a specific group of tools. Sixteen detailed the development or validation of an instrument. Fifteen studies evaluated WMI and 28 evaluated WHI. Twenty-three evaluation instruments were identified. Of the seven readability tests, SMOG was predominantly used (12 of 43 studies). Eight tools measured health literacy, with REALM being the most popular instrument (7 of 43). SAM was the most commonly used presentation tool (12 of 43 studies). Many tools are available to evaluate WMI and WHI. However, the majority are researcher focused. Most evaluate readability and presentation, revealing a gap in valid and reliable tools for assessing quality of information, and those that can be used by consumers.

Consumer Understanding of Prescription Drug Information: An Illustration Using an Antidepressant Medication

Background

Patient education and warnings have emerged as prominent interventions for improving drug safety. As part of the provision of information and guidance on safe use of drugs, patients often receive multiple pieces of written information when they obtain a prescription medication, including a Food and Drug Administration (FDA)–mandated medication guide (MG), consumer medication information (CMI), and patient package insert (PPI).

Objective:

To determine whether patients understand the materials providing drug information and whether the materials convey the intended information.

Methods:

Fifty-two adults with a high school education or less were shown an actual (blinded) MG, CMI, and PPI for a marketed antidepressant medication. Comprehension was tested with methods used by the FDA to assess label comprehension for nonprescription products.

Results:

The majority of participants (88.2%) looked at all 3 pieces of information provided. The mean (SD) time spent reviewing the CMI was 5.2 (4.8) minutes (range 0-21.9). 16.5(13.3) minutes for the PPI (range 0-43.0), and 2.5 (1.6) minutes for the MG (range 0-7.6). Less than 20% of participants were able to identify the symptoms of a rare but potentially life-threatening situation that can occur with this medication and only 61.5% recalled the risk of teen suicide, which is the sole focus of the MG. Respondents with lower literacy scores performed more poorly than those with higher literacy scores.

Conclusions:

Information provided with at least some prescription drugs is not adequately understood by less-educated consumers and does not effectively communicate critical safety messages or directions.

Malaria rapid diagnostic kits: quality of packaging, design and labelling of boxes and components and readability and accuracy of information inserts

BACKGROUND

The present study assessed malaria RDT kits for adequate and correct packaging, design and labelling of boxes and components. Information inserts were studied for readability and accuracy of information.

METHODS

Criteria for packaging, design, labelling and information were compiled from Directive 98/79 of the European Community (EC), relevant World Health Organization (WHO) documents and studies on end-users' performance of RDTs. Typography and readability level (Flesch-Kincaid grade level) were assessed.

RESULTS

Forty-two RDT kits from 22 manufacturers were assessed, 35 of which had evidence of good manufacturing practice according to available information (i.e. CE-label affixed or inclusion in the WHO list of ISO13485:2003 certified manufacturers). Shortcomings in devices were (i) insufficient place for writing sample identification (n=40) and (ii) ambiguous labelling of the reading window (n=6). Buffer vial labels were lacking essential information (n=24) or were of poor quality (n=16). Information inserts had elevated readability levels (median Flesch Kincaid grade 8.9, range 7.1-12.9) and user-unfriendly typography (median font size 8, range 5-10). Inadequacies included (i) no referral to biosafety (n=18), (ii) critical differences between depicted and real devices (n=8), (iii) figures with unrealistic colours (n=4), (iv) incomplete information about RDT line interpretations (n=31) and no data on test characteristics (n=8). Other problems included (i) kit names that referred to Plasmodium vivax although targeting a pan-species Plasmodium antigen (n=4), (ii) not stating the identity of the pan-species antigen (n=2) and (iii) slight but numerous differences in names displayed on boxes, device packages and information inserts. Three CE labelled RDT kits produced outside the EC had no authorized representative affixed and the shape and relative dimensions of the CE symbol affixed did not comply with the Directive 98/79/EC. Overall, RDTs with evidence of GMP scored better compared to those without but inadequacies were observed in both groups.

CONCLUSION

Overall, malaria RDTs showed shortcomings in quality of construction, design and labelling of boxes, device packages, devices and buffers. Information inserts were difficult to read and lacked relevant information.

A randomized trial of pictorial versus prose-based medication information pamphlets

OBJECTIVE

The goal of this study was to compare prose and pictorial-based information pamphlets about the medication methotrexate in the domains of free recall, cued recall, comprehension and utility.

METHODS

A single blind, randomized trial of picture versus prose-based information pamphlets including 100 participants aged 18-65 years of age, who had not completed high school, could read English, and had no prior knowledge about methotrexate. Superiority of pamphlet type was assessed using immediate free recall, cued recall and comprehension.

RESULTS

There were no differences between picture and prose pamphlets in free recall, cued recall, and comprehension either immediately or after a 1-week interval. Immediate free recall of important information was 17-26%; free recall fell even lower to 7-16% after 1 week. The pictorial pamphlet was preferred over the prose-based pamphlet.

CONCLUSION

This study found no benefit in free recall, cued recall, or comprehension through the addition of pictograms to a simple prose-based medication pamphlet.

PRACTICE IMPLICATIONS

In order for them to be effective in clinical practice, even simple medication information pamphlets that have been assessed for patients' ability to comprehend them cannot be used as the sole means for conveying important medication-related information to patients.

Making sense of home pregnancy test instructions

OBJECTIVE

To examine readability and related formatting characteristics of English language instructions accompanying home pregnancy tests (HPTs).

METHODS

We identified 16 HPTs; however, because of duplicate instructions, our final sample included 13 unique sets of HPT instructions (brand names, n = 9; store brand, n = 4). Reading grade level of How to Use and Interpret Results and General Information sections were calculated using the Simple Measure of Gobbledygoop readability formula. Total number of graphics was tallied. Foldout dimension, text point size, and graphic dimensions were measured to the nearest millimeter with a standard ruler. We also assessed layout features, graphic characteristics, presence of a clear message, and presentation of manageable information using the User-Friendliness Tool (UFT).

RESULTS

Reading level ranged from 7th to 10th grade (mean +/- SD 8.5 +/- 0.9) for the How to Use and Interpret Results sections, and the Question and Answer sections ranged from 11th to 14th grade (mean +/- SD 12.1 +/- 0.7). Mean page length was 29.7 +/- 6.6 cm, and average page width was 23.3 +/- 7.0 cm, similar in size to an 8.5 x 11 inch sheet of paper. Graphics were used throughout HPT instructions (range 2-9), and most were similar in size to a U.S. quarter. None of the instructions scored high in all criteria on the UFT.

CONCLUSIONS

Readability and formatting characteristics of most HPT instructions do not meet recommended criteria for compliance with plain language guidelines. These findings underscore the need for improved instructions and ultimately improving patients' ability to use HPTs and interpret results with accuracy.

Do instructions for over-the-counter pre-coital female contraceptives promote "perfect use"?

BACKGROUND

This study was conducted to estimate the readability and related features of English-language over-the-counter (OTC) pre-coital female contraceptive (PFC) instructions.

STUDY DESIGN

We identified and purchased all currently available OTC PFCs (n=8), including Encare (Contraceptive Gel and Insert), F.C. Female Condom, Ortho Options (Conceptrol, Delfen and Gyncol II Jelly), Today Sponge and VCF Vaginal Film. Reading grade level was calculated using the Simple Measure of Gobbledygook. Text point size was measured and total number of graphics was tallied. Graphic dimensions were also measured. We also assessed OTC PFC instructions on four main criteria--derived from the "User-Friendliness Tool (UFT)"--including layout features, graphic characteristics, presence of a clear message and presentation of manageable information.

RESULTS

Reading level ranged from 8th to 12th grade (mean+/-SD=10.0+/-1.2). Mean page length was 24.4+/-7.0 cm (9.6+/-2.76 in.), while average page width was 20.3+/-13.8 cm (7.99+/-5.43 in.). Average text point size was 7.9+/-2.3 (range=6-12). Illustrations, predominantly line drawings, were used throughout (range=3-11), and most were similar in size to a matchbox. None of the "How to Use" sections scored high in all criteria on the UFT.

CONCLUSIONS

"How to Use" sections of OTC PFC instructions should be revised to be easier to read and more user friendly. Ideally, the gap between "typical" and "perfect" contraceptive efficacy could potentially be narrowed if instructions were developed that the large majority of women could easily understand.

Do Medication Samples Jeopardize Patient Safety?

BACKGROUND

Medication samples are commonly dispensed by prescribers. Written consumer medication information (CMI) provided with sample packaging is an important source of patient information. Although one-third of Americans have health literacy deficiencies, previous studies have found that CMI is often too complex for many patients to understand. This may prevent patients from using these medications appropriately.

OBJECTIVE

To evaluate readability and formatting characteristics of CMI included with nonsolid (ie, topical cream/lotion, inhalation, transdermal) drug samples.

METHODS

We collected a convenience sample of nonsolid dosage sample medications (N = 55) from several different private and university-affiliated primary care and specialty physician practices at a large academic medical center in the southeastern US. We noted whether CMI was present and, if it was, we assessed it for instruction presentation, reading level, text size, format/layout, and comprehensibility.

RESULTS

Most (43 of 55) products included CMI, either as a separate leaflet or directly on the packaging. Reading level of CMI leaflets ranged from the 6th- to 14th-grade level, with just 4 (16.0%) written at the recommended 6th-grade level. Text font point size was 9.48 ± 2.14 (mean ± SD; range 5–12). Text printed directly on sample packaging averaged 6.61 point ± 2.62 (4–11) font size. Ninety-two percent of CMI leaflets included a combination of text and pictures; only 11.1% of CMI printed directly on the packaging used pictorial aids.

CONCLUSIONS

Most CMI accompanying nonsolid medication samples is written at a reading level that exceeds that of many consumers and does not meet recommended standards for readability and comprehensibility of patient education material.
