Development and evaluation of pictograms on medication labels for patients with limited literacy skills in a culturally diverse multiethnic population

Gender differences in the context of interventions for improving health literacy in migrants: a qualitative evidence synthesis

BACKGROUND

Health literacy can be defined as a person's knowledge, motivation and competence in four steps of health-related information processing - accessing, understanding, appraising and applying health-related information. Individuals with experience of migration may encounter difficulties with or barriers to these steps that may, in turn, lead to poorer health outcomes than those of the general population. Moreover, women and men have different health challenges and needs and may respond differently to interventions aimed at improving health literacy. In this review, we use 'gender' rather than 'sex' to discuss differences between men and women because gender is a broad term referring to roles, identities, behaviours and relationships associated with being male or female.

OBJECTIVES

The overall objective of this qualitative evidence synthesis (QES) was to explore and explain probable gender differences in the health literacy of migrants. The findings of this QES can provide a comprehensive understanding of the role that any gender differences can play in the development, delivery and effectiveness of interventions for improving the health literacy of female and male migrants. This qualitative evidence synthesis had the following specific objectives: - to explore whether there are any gender differences in the health literacy of migrants; - to identify factors that may underlie any gender differences in the four steps of health information processing (access, understand, appraise, and apply); - to explore and explain gender differences found - or not found - in the effectiveness of health literacy interventions assessed in the effectiveness review that is linked to this QES (Baumeister 2023); - to explain - through synthesising findings from Baumeister 2023 and this QES - to what extent gender- and migration-specific factors may play a role in the development and delivery of health literacy interventions.

SEARCH METHODS

We conducted electronic searches in MEDLINE, CINAHL, PsycINFO and Embase until May 2021. We searched trial registries and conference proceedings. We conducted extensive handsearching and contacted study authors to identify all relevant studies. There were no restrictions in our search in terms of gender, ethnicity or geography.

SELECTION CRITERIA

We included qualitative trial-sibling studies directly associated with the interventions identified in the effectiveness review that we undertook in parallel with this QES. The studies involved adults who were first-generation migrants (i.e. had a direct migration experience) and used qualitative methods for both data collection and analysis.

DATA COLLECTION AND ANALYSIS

We extracted data into a form that we developed specifically for this review. We assessed methodological limitations in the studies using the CASP (Critical Appraisal Skills Programme) Qualitative Studies) checklist. The data synthesis approach that we adopted was based on "best fit" framework synthesis. We used the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) approach to assess our level of confidence in each finding. We followed PRISMA-E guidelines to report our findings regarding equity.

MAIN RESULTS

We included 27 qualitative trial-sibling studies directly associated with 24 interventions assessed in a linked effectiveness review (Baumeister 2023), which we undertook in parallel with this QES. Eleven studies included only women, one included only men and 15 included both. Most studies were conducted in the USA or Canada and primarily included people of Latino/Latina and Hispanic origin. The second most common origin was Asian (e.g. Chinese, Korean, Punjabi). Some studies lacked information about participant recruitment and consideration of ethical aspects. Reflexivity was lacking: only one study contained a reflection on the relationship between the researcher and participants and its impact on the research. None of the studies addressed our primary objective. Only three studies provided findings on gender aspects; these studies were conducted with women only. Below, we present findings from these studies, with our level of confidence in the evidence added in brackets. Accessing health information We found that 'migrant women of Korean and Afghan origin preferred access to a female doctor' (moderate confidence) for personal reasons or due to cultural norms. Our second finding was that 'Afghan migrant women considered their husbands to be gatekeepers', as women of an Afghan background stressed that, in their culture, the men were the heads of the household and the decision-makers, including in personal health matters that affected their wives (low confidence). Our third finding was 'Afghan migrant women reported limited English proficiency' (moderate confidence), which impeded their access to health information and services. Understanding health information Female migrants of Afghan background reported limited writing and reading abilities, which we termed 'Afghan migrant women reported low literacy levels' (moderate confidence). Applying health information Women of Afghan and Mexican backgrounds stated that the 'women's role in the community' (moderate confidence) prevented them from maintaining their own health and making themselves a priority; this impeded applying health information. Appraising health information We did not find any evidence related to this step in health information processing. Other findings In the full text of this QES, we report on migration-specific factors in health literacy and additional aspects related to health literacy in general, as well as how participants assessed the effectiveness of health literacy interventions in our linked effectiveness review. Moreover, we synthesised qualitative data with findings of the linked effectiveness review to report on gender- and migration-specific aspects that need to be taken into account in the development, design and delivery of health literacy interventions.

AUTHORS' CONCLUSIONS

The question of whether gender differences exist in the health literacy of migrants cannot be fully answered in this qualitative evidence synthesis. Gender-specific findings were presented in only three of the 27 included studies. These findings represented only Afghan, Mexican and Korean women's views and were probably culturally-specific. We were unable to explore male migrants' perceived health literacy due to the notable lack of research involving migrant men. Research on male migrants' perceived health literacy and their health-related challenges is needed, as well as more research on potential gender roles and differences in the context of migration. Moreover, there is a need for more research in different countries and healthcare systems to create a more comprehensive picture of health literacy in the context of migration.

Pharmaceutical pictograms to improve textual comprehension: A systematic review

INTRODUCTION

Written instructive information for the patient is key in pharmaceutical care. However, the preexisting literature agrees on the discordance between the readability of written medication messages intended for patients. The aim of our work was to systematically review the available evidence on the effect of pharmaceutical pictograms as elements that facilitate understanding of the text in primary or secondary medication packaging.

METHODS

A parallel systematic search was conducted of the literature covering evidence of the effect of including pictograms in primary or secondary packaging on comprehension by potential users or caregivers up to April 9, 2023. The databases consulted were Scopus, MEDLINE and Web of Science. Only randomized controlled studies, whose main outcome measure was comprehension, were included.

RESULTS

Only 8 papers met our search criteria. In most of the included studies, the intervention of including pictograms improved participants' performance in comprehending instructions. A debatable methodological quality, and differences in the target population, textual complexity of the materials or the cultural affinity of the pictograms with the target population in each study, could have had a decisive influence on the results.

CONCLUSION

The heterogeneity in the design of each study poses a significant barrier to establishing commonalities and generalizing the results. This heterogeneity also prevented us from conclusively confirming the usefulness of pictograms complementary to instructional text in improving the comprehension of instructions for the rational use of medicines.

Comprehension of US Pharmacopeia and South African pictograms by sub-Saharan migrants who newly arrived in Europe

BACKGROUND

Patient understanding of health information is crucial for successful pharmaceutical care. Pharmaceutical pictograms enable communication of medication instructions to patients who may not share a common language or are illiterate. However, cultural factors can impact the accurate interpretation of these visual aids.

OBJECTIVES

This study aimed to assess and compare the comprehensibility of two sets of pictograms from different cultural backgrounds among sub-Saharan migrants recently arrived in Europe.

METHODS

In June 2022, a cross-sectional survey was conducted at the Migrant Temporary Stay Center in Melilla, Spain. Participants were randomly assigned to interpret 10 pictograms from either the U.S. Pharmacopeia or South African counterparts, with a minimum of 50 participants per group. Following the International Organization for Standardization's testing comprehensibility criterion, pictograms achieving a 66.7% correct interpretation rate were considered acceptable. Health literacy was measured using a culturally validated sub-Saharan version of the European Health Literacy Survey Questionnaire (HLS-EU-Q16). Data analysis included Fisher's exact test or chi-square test (for qualitative variables) and the Mann-Whitney test (for quantitative variables).

RESULTS

A total of 106 participants were included (51 in the U.S. pharmacopeia group and 55 in the South African group). None of the assessed pictograms met the comprehensibility criterion, and both groups exhibited high nonresponse rates. The South African pictograms were better understood than the American ones for all intended messages, with a statistically significant difference in overall comprehension (p = 0.002). Additionally, the participants' country of birth was a statistically significant factor for comprehension (p = 0.019).

CONCLUSIONS

Our findings indicate that evaluated pharmaceutical pictograms cannot be validly used in newly arrived sub-Saharan immigrants in Europe. However, the significantly better comprehension of South African pictograms compared to North American ones highlights the importance of cultural alignment between pictograms and their prospective users for effective comprehensibility.

Interventions for improving health literacy in migrants

BACKGROUND

Health literacy (HL) is a determinant of health and important for autonomous decision-making. Migrants are at high risk for limited HL. Improving HL is important for equitable promotion of migrants' health.

OBJECTIVES

To assess the effectiveness of interventions for improving HL in migrants. To assess whether female or male migrants respond differently to the identified interventions.

SEARCH METHODS

We ran electronic searches to 2 February 2022 in CENTRAL, MEDLINE, Embase, PsycInfo and CINAHL. We also searched trial registries. We used a study filter for randomised controlled trials (RCTs) (RCT classifier).

SELECTION CRITERIA

We included RCTs and cluster-RCTs addressing HL either as a concept or its components (access, understand, appraise, apply health information).

DATA COLLECTION AND ANALYSIS

We used the methodological procedures recommended by Cochrane and followed the PRISMA-E guidelines. Outcome categories were: a) HL, b) quality of life (QoL), c) knowledge, d) health outcomes, e) health behaviour, f) self-efficacy, g) health service use and h) adverse events. We conducted meta-analysis where possible, and reported the remaining results as a narrative synthesis.

MAIN RESULTS

We included 28 RCTs and six cluster-RCTs (8249 participants), all conducted in high-income countries. Participants were migrants with a wide range of conditions. All interventions were adapted to culture, language and literacy. We did not find evidence that HL interventions cause harm, but only two studies assessed adverse events (e.g. anxiety). Many studies reported results for short-term assessments (less than six weeks after total programme completion), reported here. For several comparisons, there were also findings at later time points, which are presented in the review text. Compared with no HL intervention (standard care/no intervention) or an unrelated HL intervention (similar intervention but different information topic) Self-management programmes (SMP) probably improve self-efficacy slightly (standardised mean difference (SMD) 0.28, 95% confidence interval (CI) 0.06 to 0.50; 2 studies, 333 participants; moderate certainty). SMP may improve HIV-related HL (understanding (mean difference (MD) 4.25, 95% CI 1.32 to 7.18); recognition of HIV terms (MD 3.32, 95% CI 1.28 to 5.36)) (1 study, 69 participants). SMP may slightly improve health behaviours (3 studies, 514 participants), but may have little or no effect on knowledge (2 studies, 321 participants) or subjective health status (MD 0.38, 95% CI -0.13 to 0.89; 1 study, 69 participants) (low certainty). We are uncertain of the effects of SMP on QoL, health service use or adverse events due to a lack of evidence. HL skills building courses (HLSBC) may improve knowledge (MD 10.87, 95% CI 5.69 to 16.06; 2 studies, 111 participants) and any generic HL (SMD 0.48, 95% CI 0.20 to 0.75; 2 studies, 229 participants), but may have little or no effect on depression literacy (MD 0.17, 95% CI -1.28 to 1.62) or any health behaviour (2 studies, 229 participants) (low certainty). We are uncertain if HLSBC improve QoL, health outcomes, health service use, self-efficacy or adverse events, due to very low-certainty or a lack of evidence. Audio-/visual education without personal feedback (AVE) probably improves depression literacy (MD 8.62, 95% CI 7.51 to 9.73; 1 study, 202 participants) and health service use (MD -0.59, 95% CI -1.11 to -0.07; 1 study, 157 participants), but probably has little or no effect on health behaviour (risk ratio (RR) 1.07, 95% CI 0.91 to 1.25; 1 study, 135 participants) (moderate certainty). AVE may improve self-efficacy (MD 3.51, 95% CI 2.53 to 4.49; 1 study, 133 participants) and may slightly improve knowledge (MD 8.44, 95% CI -2.56 to 19.44; 2 studies, 293 participants) and intention to seek depression treatment (MD 1.8, 95% CI 0.43 to 3.17), with little or no effect on depression (SMD -0.15, 95% CI -0.40 to 0.10) (low certainty). No evidence was found for QoL and adverse events. Adapted medical instruction may improve understanding of health information (3 studies, 478 participants), with little or no effect on medication adherence (MD 0.5, 95% CI -0.1 to 1.1; 1 study, 200 participants) (low certainty). No evidence was found for QoL, health outcomes, knowledge, health service use, self-efficacy or adverse events. Compared with written information on the same topic SMP probably improves health numeracy slightly (MD 0.7, 95% CI 0.15 to 1.25) and probably improves print literacy (MD 9, 95% CI 2.9 to 15.1; 1 study, 209 participants) and self-efficacy (SMD 0.47, 95% CI 0.3 to 0.64; 4 studies, 552 participants) (moderate certainty). SMP may improve any disease-specific HL (SMD 0.67, 95% CI 0.27 to 1.07; 4 studies, 955 participants), knowledge (MD 11.45, 95% CI 4.75 to 18.15; 6 studies, 1101 participants) and some health behaviours (4 studies, 797 participants), with little or no effect on health information appraisal (MD 1.15, 95% CI -0.23 to 2.53; 1 study, 329 participants) (low certainty). We are uncertain whether SMP improves QoL, health outcomes, health service use or adverse events, due to a lack of evidence or low/very low-certainty evidence. AVE probably has little or no effect on diabetes HL (MD 2, 95% CI -0.15 to 4.15; 1 study, 240 participants), but probably improves information appraisal (MD -9.88, 95% CI -12.87 to -6.89) and application (RR 1.51, 95% CI 1.29 to 1.77) (1 study, 608 participants; moderate certainty). AVE may slightly improve knowledge (MD 8.35, 95% CI -0.32 to 17.02; low certainty). No short-term evidence was found for QoL, depression, health behaviour, self-efficacy, health service use or adverse events. AVE compared with another AVE We are uncertain whether narrative videos are superior to factual knowledge videos as the evidence is of very low certainty. Gender differences Female migrants' diabetes HL may improve slightly more than that of males, when receiving AVE (MD 5.00, 95% CI 0.62 to 9.38; 1 study, 118 participants), but we do not know whether female or male migrants benefit differently from other interventions due to very low-certainty or a lack of evidence.

AUTHORS' CONCLUSIONS

Adequately powered studies measuring long-term effects (more than six months) of HL interventions in female and male migrants are needed, using well-validated tools and representing various healthcare systems.

Comprehension of prescription orders with and without pictograms: tool validation and comparative assessment among a sample of participants from a developing country

BACKGROUND

Medication errors can often occur due to the patient's inability to comprehend written or verbal medication orders. This study aimed to develop pictograms of selected medication orders and to validate the comprehension of prescription orders index and compare the comprehension scores with and without pictograms. In addition to determine the predictors that could be associated with a better or worse comprehension of prescription orders with pictograms versus that of their written counterparts.

METHODS

A cross-sectional study was conducted using a snowball sampling technique. Six pictograms were developed to depict specific medication orders. The comprehension of prescription orders index was constructed and validated. The study then compared the comprehension scores of prescription orders with and without pictograms, and identified the predicting factors score difference.

RESULTS

A total of 1848 participants were included in the study. The structure of the comprehension of prescription orders index was validated over a solution of four factors, with an adequate Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy of 0.711 and a significant Bartlett's test of sphericity (P < 0.001). The construct validity of the index was further confirmed by highly significant correlations between each item and the full index (P < 0.001). The study also found a significant association between the difference in comprehension scores for prescription orders with and without pictograms and several factors, including age, level of education, area of residence, number of children, and smoking status with the difference of comprehension scores (P < 0.001).

CONCLUSION

Pictogram-based instructions of medication orders were better understood by the Lebanese population than written instructions, making the incorporation of pictograms in pharmacy practice paramount to optimize medication use by the patient and thus yielding better health outcomes.

Challenges encountered by pharmacy staff in using prescription medication labels during medication counselling with older adults and solutions employed: A mixed-methods study

Background

Prescription medication labels (PMLs) predominantly dispensed in English, are an important adjunct to medication counselling. PMLs are routinely used by pharmacy staff to counsel older adults about their medications. This study sought to identify challenges that pharmacy staff observe older adults face in using their PMLs, and to identify and quantify solutions employed by pharmacy staff during medication counselling to address such challenges.

Methods

Ten in-depth interviews were done with primary care pharmacy staff to gather the range of challenges and solutions. Subsequently, a quantitative survey, informed by the qualitative findings, was administered to 121 pharmacy staff to assess if the reported solutions were commonly used.

Results

The two main challenges were incongruity between PML language (English) and older adults' language proficiency, and poor PML legibility. The solutions, classified under three themes, were simplifying medication information on PMLs, supplementing PMLs with additional medication information and mitigating poor readability.

Conclusions

Pharmacy staff observed challenges faced by older adults in using PMLs during medication counselling. Ad-hoc improvisations by pharmacy staff to PMLs were pervasive. System-level PML improvements, such as provision of legible bilingual medication instructions, pharmaceutical pictograms and additional medication information, through patient information leaflets or using quick response (QR) codes on PMLs, should be considered. This will facilitate patient-provider communication, especially in settings with language dissonance between PMLs and patients.

Barriers and facilitators experienced by migrants and refugees when accessing pharmaceutical care: A scoping review

BACKGROUND

Pharmacists in the community are often among the first health professionals encountered by new arrivals. Their accessibility and the longevity of the relationship gives pharmacy staff unique opportunities to work with migrants and refugees to meet their health needs. While the language, cultural and health literacy barriers that cause poorer health outcomes are well documented in medical literature, there is a need to validate the barriers to accessing pharmaceutical care and to identify facilitators for efficient care in the migrant/refugee patient-pharmacy staff interaction.

OBJECTIVE

The purpose of this scoping review was to investigate the barriers and facilitators that migrant and refugee populations experience when accessing pharmaceutical care in host countries.

METHODS

A comprehensive search of Medline, Emcare on Ovid, CINAHL and SCOPUS databases, guided by the PRISMA-ScR statement, was undertaken to identify the original research published in English between 1990 and December 2021. The studies were screened based on inclusion and exclusion criteria.

RESULTS

A total of 52 articles from around the world were included in this review. The studies revealed that the barriers to migrants and refugees accessing pharmaceutical care are well documented and include language, health literacy, unfamiliarity with health systems, and cultural beliefs and practises. Empirical evidence was less robust for facilitators, but suggested strategies included improvement of communication, medication review, community education and relationship building.

CONCLUSIONS

While barriers experienced are known, there is a lack of evidence for facilitators for provision of pharmaceutical care to refugees and migrants and poor uptake of available tools and resources. There is a need for further research to identify facilitators that are effective in improving access to pharmaceutical care and practical for implementation by pharmacies..

Exploring the Use of Pictograms in Privacy Agreements to Facilitate Communication Between Users and Data Collecting Entities: Randomized Controlled Trial

BACKGROUND

Privacy agreements can foster trust between users and data collecting entities by reducing the fear of data sharing. Users typically identify concerns with their data privacy settings, but due to the complexity and length of privacy agreements, users opt to quickly consent and agree to the terms without fully understanding them.

OBJECTIVE

This study explores the use of pictograms as potential elements to assist in improving the transparency and explanation of privacy agreements.

METHODS

During the development of the pictograms, the Double Diamond design process was applied for 3 instances of user interactions and 3 iterations of pictograms. The testing was done by performing a comparative study between a control group, which received no pictograms, and an experimental group, which received pictograms. The pictograms were individually tested to assess their efficacy by using an estimated comprehension of information symbols test.

RESULTS

A total of 57 participants were recruited for the pictogram evaluation phase. With the addition of pictograms, the overall understanding improved by 13% (P=.001), and the average time spent answering the questions decreased by 57.33 seconds. A 9% decrease in perceived user frustration was also reported by users, but the difference was not significant (χ²₄=4.80; P=.31). Additionally, none of the pictograms passed the estimated comprehension of information symbols test, with 7 being discarded immediately and 5 requiring further testing to assess their efficacy.

CONCLUSIONS

The addition of pictograms appeared to improve users' understanding of the privacy agreements, despite the pictograms needing further changes to be more understandable. This proves that with the aid of pictographic images, it is possible to make privacy agreements more accessible, thereby allowing trust and open communication to be fostered between users and data collecting entities.

Graphical user interface design to improve understanding of the patient-reported outcome symptom response

BACKGROUND

Symptom monitoring application (SMA) has clinical benefits to cancer patients but patients experience difficulties in using it. Few studies have identified which types of graphical user interface (GUI) are preferred by cancer patients for using the SMA.

METHODS

This is a cross-sectional study aimed to identify preferred GUI among cancer patients to use SMA. Total of 199 patients were asked to evaluate 8 types of GUIs combining text, icon, illustration, and colors using mixed-methods. Subgroup analyses were performed according to age and gender.

RESULTS

The mean age of the patients was 57 and 42.5% was male. The most preferred GUI was "Text + Icon + Color" (mean = 4.43), followed by "Text + Icon" (mean = 4.39). Older patients (≥ 60 years) preferred "Text + Icon" than younger patients (p for interaction < 0.01). Simple and intuitive text and icons were the most useful GUI for cancer patients to use the SMA.

CONCLUSION

Simple and intuitive text and icons were the most useful GUI for cancer patients to use the SMA. Researchers need to be careful when applying realistic face drawings to cancer symptom monitoring applications because they can recall negative images of cancer.

Pictograms to aid laypeople in identifying the addictiveness of gambling products (PictoGRRed study)

The structural addictive characteristics of gambling products are important targets for prevention, but can be unintuitive to laypeople. In the PictoGRRed (Pictograms for Gambling Risk Reduction) study, we aimed to develop pictograms that illustrate the main addictive characteristics of gambling products and to assess their impact on identifying the addictiveness of gambling products by laypeople. We conducted a three-step study: (1) use of a Delphi consensus method among 56 experts from 13 countries to reach a consensus on the 10 structural addictive characteristics of gambling products to be illustrated by pictograms and their associated definitions, (2) development of 10 pictograms and their definitions, and (3) study in the general population to assess the impact of exposure to the pictograms and their definitions (n = 900). French-speaking experts from the panel assessed the addictiveness of gambling products (n = 25), in which the mean of expert's ratings was considered as the true value. Participants were randomly provided with the pictograms and their definitions, or with a standard slogan, or with neither (control group). We considered the control group as representing the baseline ability of laypeople to assess the addictiveness of gambling products. Each group and the French-speaking experts rated the addictiveness of 14 gambling products. The judgment criterion was the intraclass coefficients (ICCs) between the mean ratings of each group and the experts, reflecting the level of agreement between each group and the experts. Exposure to the pictograms and their definition doubled the ability of laypeople to assess the addictiveness of gambling products compared with that of the group that read a slogan or the control group (ICC = 0.28 vs. 0.14 (Slogan) and 0.14 (Control)). Laypeople have limited awareness of the addictive characteristics of gambling products. The pictograms developed herein represent an innovative tool for universally empowering prevention and for selective prevention.

Comprehensibility of a personalized medication overview compared to usual-care prescription drug labels

Poor understanding of prescription drug label (PDL) instructions can lead to medication errors, suboptimal treatment (side) effects, and non-adherence. A personalized medication hard-copy overview listing PDL instructions and visual information may support patients in their medication use. This study aimed to investigate the comprehensibility of PDL instructions on a personalized medication overview compared to usual-care PDL instructions presented on a medication box. A hypothetical-online-experiment was set up, comparing groups of respondents exposed vs not exposed to the medication overview and who received PDL instructions for three, five, or eight medications. Participants were divided randomly in six groups. Online questionnaires were sent to a stratified sample of 900 members from the Nivel Dutch Healthcare Consumer Panel. Outcome measures included comprehension of instructions for medication use, e.g. how often, dose timing, usage advice and warnings for a medication with simple use instructions (omeprazol) and more complex use instructions (levodopa/carbidopa (L/C)). To analyze differences between experimental conditions ANOVA testing was used. 604 respondents (net response 67%) completed the questionnaires. Respondents exposed (E) to the overview gave a higher proportion of correct answers compared to non-exposed (NE) respondents for usage advice (L/C: mean 0.83, SD 0.4 E; 0.03, SD 0.2 NE, p &lt; 0.001; omeprazol: mean 0.85, SD 0.4 E; 0.10, SD 0.3 NE, p &lt; 0.001). Both groups gave the same proportion of correct answers (mean 0.80, SD 0.4, p = 1.0) for dose timing of omeprazol. More NE respondents gave correct answers for how often (mean 0.85, SD 0.4 NE; mean 0.76, SD 0.4 E, p = 0.02) and dose timing (mean 0.92, SD 0.3 NE; mean 0.86, SD 0.4 E, p = 0.04) of L/C. No differences were found regarding number of medications nor were interaction effects found between the number of medications and information type. As a medication overview contains additional information, it can be a good addition in supporting patients in their medication use compared to usual-care PDLs. Future research should focus on identifying patient groups who might benefit more from a medication overview, by testing the effect of such overview on this group.

Change in Risk Score and Behaviors of Soft Contact Lens Wearers After Targeted Patient Education

OBJECTIVES

To determine if targeted education can influence the behaviors and scores of soft contact lens (SCL) wearers via the Contact Lens Risk Survey (CLRS).

METHODS

This was a multicenter, prospective, case-control study. Cases were symptomatic red eye SCL wearers (age, 18-39 years), and controls were age , sex, and site matched. Participants completed the CLRS and were provided targeted patient education at three time points: baseline, one, and six months. Change in scores and behaviors were analyzed using the Wilcoxon signed rank test.

RESULTS

Forty-one cases and 71 controls were analyzed. The mean risk score (mean±SE) from baseline to follow-up improved (reduced) for all participants (-1.96±0.73; P=0.01), mostly driven by the improvement among cases (-2.55±1.32; P=0.05). Case subjects reported a decrease in frequency of wearing lenses while showering (-0.32±0.07; P<0.0001), discarding lens solution (-0.13±0.06; P=0.03), and rinsing lenses with tap water (-0.19±0.08; P=0.02) after targeted education.

CONCLUSIONS

Targeted patient education can influence some behaviors of SCL wearers, especially those who experienced a red eye event. Further study is needed to determine how to improve other risk behaviors and whether these changes are sustained long term.

Communicating with patients through pictograms and pictures - a scoping review

BackgroundCommunication between patients and Health Care Workers (HCW) may on occasion be challenged by disparities in cultural background, age and educational level. Written educational material is commonly used to reduce the risk of miscommunication. However, literacy among patients may also differ and it is therefore speculated that the use of pictograms may improve patients' understanding and adherence.ObjectiveTo evaluate the scientific literature and investigate the effect and practical utility of pictograms in medical settings with focus on dermatological patients.Materials and methodsPubmed, EMBASE, and Cochrane Library were searched July 2021 for studies regarding use of pictograms in medical settings and dermatology.ResultsThe use of pictograms in dermatology is not well characterized, but studies in other fields of medicine report a positive effect of using pictograms in communication. Pictograms have a significant positive effect when presented alongside verbal or written explanations.ConclusionThe quality of the development process is important to ensure the utility of any pictogram. Involving the target population in the design and validation of the pictograms may be critical. In the validation process, testing of transparency and translucency may benefit from international recommendations.

Evaluation of pharmaceutical pictogram comprehension among adults in the Philippines

Background

The use of pharmaceutical pictograms to enhance patients’ understanding of drug regimens has been proven effective in many countries. There are two reference systems for pictograms generally used in pharmacy: the United States Pharmacopeia (USP) and International Pharmacy Federation (FIP). This study aimed to evaluate the effectiveness of USP and FIP pictograms among adults in the Philippines by identifying how many pictograms would pass the American National Standards Institute (ANSI) criterion of 85% comprehension, and to describe the factors affecting pictograms’ comprehension.

Methods

A descriptive cross-sectional research using a face-to-face interview was performed to evaluate 108 pictograms in 52 Filipino adults enrolled through quota sampling. Descriptive statistics, Mann–Whitney U test (Wilcoxon rank-sum test), univariate linear regression, and multiple linear regression were used to statistically analyze the data collected.

Results

Only 17 (16 USP and 1 FIP) out of the 108 pictograms (15.74%) passed the ANSI criterion. The median score of Filipinos was 71 out of 108 pictograms (Interquartile range: 10–96). The multivariate model (R² = 0.5645, F (4,47) = 15.23) suggested that the score was lower by 5.85 points if the user was female, 21.58 points lower if the participant was below Grade 12 education level, and 1.20 points lower if the patient was greater than 46 years old. Education level was identified as the significant predictor (p-value < 0.0000*, power = 99.98%). The participant with greater than Grade 12 has a higher comprehension score of rank-sum 952.5 (Expected = 689) compared to only 425.5 (Expected = 689).

Conclusions

Since only 17 pictograms passed as stand-alone tool for patient information material, the researchers recommend the use of verbal and written instructions to complement pictograms to enhance comprehension. Furthermore, the government should consider the inclusion of health pictograms in basic health education.

Validation of pharmaceutical pictograms among older adults with limited English proficiency

OBJECTIVE

Pictograms on prescription medication labels enhance medication literacy and medication adherence. However, pictograms need to be contextually validated. We assessed the validity of 52 International Pharmaceutical Federation pictograms among 250 older Singaporeans with limited English proficiency.

METHODS

Participants were randomly assigned 11 pictograms each. For each pictogram, participants were first asked its intended meaning. Then, they were told the intended meaning and asked to rate how well the pictogram represented the meaning, on a scale of 1-7. Pictograms were classified as valid (≥66% participants assigned the pictogram interpreted its intended meaning correctly [transparency criterion] and ≥85% participants rated its representativeness as ≥5 [translucency criterion]), partially valid (only transparency criterion was fulfilled) or not valid. Open-ended questions gathered feedback to improve pictograms.

RESULTS

14 pictograms (26.9%) achieved validity and 6 pictograms (11.5%) achieved partial validity. A greater proportion of pictograms for dose and route of administration, and dosage frequency achieved validity or partial validity versus those depicting precautions, indications or side effects.

CONCLUSION

Majority (61.5%) of the assessed pictograms did not achieve validity or partial validity, highlighting the importance of contextual validation.

PRACTICE IMPLICATIONS

Low pictogram comprehension emphasizes the importance of facilitating pictogram understanding during medication counseling.

Visual aids in ambulatory clinical practice: Experiences, perceptions and needs of patients and healthcare professionals

This study aims to explore how visual aids (VA) are used in ambulatory medical practice. Our research group (two doctors, one graphic designer and one sociologist) have led a qualitative study based on Focus Groups. A semi-structured guide and examples of VA were used to stimulate discussions. Participants were healthcare professionals (HP) working in ambulatory practice in Geneva and French-speaking outpatients. After inductive thematic analysis, the coding process was analyzed and modified to eventually reach consensus. Six focus groups gathered twenty-one HP and fifteen patients. Our study underlines the variety of purposes of use of VA and the different contexts of use allowing the distinction between “stand-alone” VA used out of consultation by patients alone and “interactive” VA used during a consultation enriched by the interaction between HP and patients. HP described that VA can take the form of useful tools for education and communication during consultation. They have questioned the quality of available VA and complained about restricted access to them. Patients expressed concern about the impact of VA on the interaction with HP. Participants agreed on the beneficial role of VA to supplement verbal explanation and text. Our study emphasizes the need to classify available VA, guarantee their quality, facilitate their access and deliver pertinent instructions for use.

Older adult and family caregiver experiences with prescription medication labels and their suggestions for label improvement

Background

Prescription medication labels (PMLs) are an important source of written medication information for patients. However, real-world PMLs do not entirely conform with available labelling best practices and guidelines. Given this disconnect, older adults remain particularly at risk of misinterpreting their PMLs. Past studies have commonly assessed hypothetical PMLs, warranting studies that explore the lived experiences of older adults with real-world PMLs. Furthermore, the perspective of family caregivers of older adults is yet to be studied.

Objective(s)

This qualitative study documented the challenges faced by older adults and their family caregivers in using real-world PMLs, their strategies to cope with these challenges, and their suggestions to improve existing PMLs.

Methods

We conducted two focus group discussions (n = 17) and 30 in-depth interviews with older adults (n = 20; including those who can read in English and those with limited English proficiency) and caregivers (n = 10) in Singapore. The data were systematically assigned to codes that were continuously refined to accommodate emergent themes.

Results

Challenges, coping strategies and suggested improvements were related to the comprehensibility, availability, readability and consistency of medication information on PMLs.

Conclusions

Real-world PMLs continue to pose challenges for older adults and their caregivers, necessitating them to seek unique and personal coping strategies. The identified PML improvements, desired by older adults and their caregivers, urge healthcare systems to implement improved PMLs. Future research should explore system-level logistical, financial, and administrative barriers (or opportunities) that hinder (or facilitate) this implementation.

•

Older adults and caregivers still face challenges with English medicine labels.

•

Small font and lack of desired information were also enduring challenges.

•

Inconsistency in label format and content confused older adults and caregivers.

•

Caregivers and pharmacy staff adopted unique strategies to help older adults.

•

Challenges and ad-hoc strategies necessitate real-world, systemic change to labels.

Medication Adherence and the Role of Pictograms in Medication Counselling of Chronic Patients: a Review

Pharmaceutical care requires a patient-centered approach, focusing on the ability of patients to understand drug-related information and follow the instructions delivered by pharmacists as well as other health-care providers included in the circle of care. With the goal of ensuring the prescribed use of medications, called medication adherence, health-care providers have to consider many risk factors such as geography (culture), social economic status, age, and low literacy that may predispose patients to non-adherence, and considerations have to be made for chronic patients living with life-long disease states. The aim of this review is to provide a balanced and comprehensive review outlining a number of different medication counselling and education approaches that have been used to try to improve medication adherence and health outcomes with the use of clear and concise graphic illustrations—called pictograms. By highlighting the current landscape of the general use and efficacy of pharmaceutical pictograms to aid in the knowledge and recall of drug-related information, as well as outlining specific medication adherence outcomes with pharmaceutical pictograms in chronic patients, the current review describes the need for health-care providers to move beyond the traditional didactic methods of oral and verbal communication with patients regarding medication-taking behavior.

Regular soft contact lens wearers' comprehension of graphical symbols labelled on multipurpose solutions

CLINICAL RELEVANCE

Symbols are commonly used to represent information of health care products included multipurpose solutions (MPSs) for contact lens (CL) care.

BACKGROUND

Little knowledge is available about recognition and comprehension by regular soft CL wearers of commonly used symbols in the instructions of CL MPSs marketed worldwide.

METHODS

CL wearers from the UK and Spain were invited to answer an anonymous on-line questionnaire (distributed though Facebook and Twitter) concerning the recognition and comprehension of seven common symbols (ISO 15223:2017 and EN 980:2008) included in MPS package instructions.

RESULTS

Answers of one hundred-ten soft CL wearers who use MPS (27 in the UK and 83 in Spain) were analysed showing low recognition and comprehension of the surveyed symbols even in wearers with > 5 years of CL wear (71.8%). The CE marked was the most recognised (96% in the UK and 88% in Spain, P = 0.29) and understood (78% in the UK and 85% in Spain, P = 0.25) symbol, but other important symbols, such as 'Caution' and 'Do not reuse', were under recognised (22% in the UK and 19% in Spain, P = 0.78 and 11% in the UK and 6% in Spain, P = 0.40 respectively) and understood (close to 30% in both countries P > 0.15). Participants with > 5 years of experience, showed slightly higher comprehension (P < 0.05) in some symbols ('Sterilised'; 'Do not reuse'; 'Use by date' and 'CE marked').

CONCLUSION

These results suggest an insufficient comprehension of seven common symbols included in MPS instructions among regular CL wearers in the UK and Spain without high impact of CL wear experience. Improving the education and symbol comprehension of regular CL wearers could help to get better patients' behaviour and safe use of MPS in soft CLs care.

Exploring the Role of Community Pharmacists in Obesity and Weight Management in Qatar: A Mixed-Methods Study

Introduction

Obesity is a major public health burden in Qatar. Pharmacists can play an important role in providing weight management services (WMSs). This study aimed to explore their attitudes, practice, perceived competence, and role in WMSs in Qatar.

Methods

A mixed-method explanatory sequential design was applied in the study. A validated online questionnaire was administered followed by qualitative individual and focus group interviews.

Results

Two-hundred seventy community pharmacists completed the survey (response rate 45%). More than half of them indicated that they often or always explain to patients the risks associated with overweight and obesity (56.2%), recommend weight loss medications, herbs or dietary supplements (52.4%), and counsel about their proper use and/or side effects (56.9%). Conversely, the majority of the pharmacists rarely or never measure patients’ waist circumference (83.8%) or calculate their body mass index (72.1%). Over 80% had very positive attitudes towards their role in weight management. Around three-quarters of the participants agreed or strongly agreed that difficulty in following-up with patients (80.7%), lack of private consultation area (75.7%), and lack of pharmacist’s time (75.2%) are barriers for implementing WMSs. More than 60% stated that they are fully competent in 7 out of 24 WMSs listed. Some themes generated include pharmacist’s role and impact in weight management, need for training about weight management, and impact of social media on patients’ perceptions.

Conclusion

Qatar community pharmacists reported positive attitudes towards the provision of WMSs. However, they identified several barriers against provision of WMSs. Several strategies are proposed to overcome barriers and to improve the provision of WMSs in community pharmacies in Qatar.

Can use of pictograms reduce liquid medication administration errors by mothers? An interventional study

Background

Liquid medication dosing errors (LMDE) made by caregivers affect treatment in children, but this is not a well-studied topic in many low-and middle-income countries including in India.

Methods

An intervention study was conducted among mothers attending a pediatric outpatient clinic of a tertiary care setting in Ujjain, India. The mothers randomly measured 12 volumes of a paracetamol liquid preparation by using a dropper (0.5 and 1 mL), measuring cup (2.5 and 5 mL), and calibrated spoon (2.5 and 5 mL) each with two instructions—oral-only measurement session (OMS) and oral plus pictogram measurement session (OPMS, the intervention). The main outcome was dosing error prevalence. The effectiveness of the intervention was assessed by measuring effect size. Risk factors for maximum LMDE were explored using backward multivariate logistic regression models. A P value of < 0.05 was considered statistically significant.

Results

In total, 310 mothers [mean (± SD) age, 30.2 (± 4.18) years] were included. LMDE prevalence in the OMS versus OPMS for dropper 0.5 mL was 60% versus 48%; for l mL dropper was 63% versus 54%; for 2.5 mL cup 62% versus 54%; for 2.5 calibrated spoon 66% versus 59%; 5 mL cup 69% versus 57%; and 5 mL calibrated spoon 68% versus 55%. Comparing OMS with OPMS, underdosing was minimum with the calibrated spoon for 2.5 mL (OR 4.39) and maximum with the dropper for 1 mL (OR 9.40), and overdosing was minimum with the dropper for 0.5 mL (OR 7.12) and maximum with the calibrated spoon for 2.5 mL (OR 13.24). The effect size (d_Cohen) of the intervention OPMS was 1.86–6.4. Risk factors for the most prevalent dosing error, that is, with the calibrated spoon for 2.5 mL, were increasing age of the mother (aOR 1.08; P = 0.026) and nuclear family (aOR 2.83; P = 0.002). The risk of dosing errors decreased with higher education of the mothers.

Conclusions

Pictograms can effectively minimize LMDE even in less educated mothers.

A scoping review of the use of visual aids in health education materials for persons with low-literacy levels

OBJECTIVE

To conduct a scoping review on the literature on visual aids in health education for persons with low-literacy.

METHODS

A scoping review methodology was employed. Pre-defined selection criteria identified 47 studies for inclusion. Data were extracted in relation to: (a) definitions of low-literacy and health literacy, (b) population studied, (c) research country, (d) consent procedures, (e) visual aids used, (f) development of visual aids, and (g) targeted outcomes.

RESULTS

Visual aids developed with persons with low-literacy demonstrated statistically significant improvements in health literacy outcomes, with benefits in medication adherence and comprehension also reported. Pictograms and videos were the most effective visual aids. Only one study adapted consent procedures for low-literacy participants.

DISCUSSION

Visual aids in health education materials may benefit persons with low-literacy levels, but large gaps in the research base are evident. Experimental research in low- and middle-income countries, with a particular focus on consent for participants with low-literacy is needed.

PRACTICE IMPLICATIONS

Visual aid design needs to include stakeholders. Consent procedures and decision-making need to be specifically adapted for participants with low-literacy.

The effectiveness of using text and pictograms on oral rehydration, dry-mixture sachet labels

Background

Medication labels are often the only information available to patients after obtaining medication from a healthcare practitioner. Pictograms are graphic symbols that have shown to increase understanding of medicine use instructions.

Aim

To compare the accuracy of the interpretation of medicine use instructions from two different oral rehydration (OR) dry-mixture sachet labels – the control ‘routine textonly’ label and an experimental label with ‘text-and-pictograms’.

Setting

Participants were recruited from waiting rooms in public primary health care (PHC) facilities in Cape Town.

Method

Each participant was required to answer six questions about OR preparation. Response accuracy was determined by comparing the participant’s answer to the actual information written on the relevant label. Afterwards, participants could offer their opinion about the label and ways to improve their understanding.

Results

Of the 132 participants who were recruited, 67 were allocated to the experimental group and 65 to the control group. Only the significant difference between the experimental and control groups for the six questions regarding the label, was recorded for the answer that could be read from a single pictogram (p = 0.00) on the experimental group’s label. When asked about this question, more control participants (15/65) found the dosing instruction difficult to understand when compared to the experimental group (1/67). A third of the control participants (22/65) indicated that they could not see or locate instructions on the label.

Conclusion

Text and pictograms on written medicine labels may be an effective tool to aid understanding of medicine use instructions amongst patients attending PHC facilities.

Provision and Need for Medicine Information in Asia and Africa: A Scoping Review of the Literature

Published reviews of written medicine information (WMI) have mainly drawn on studies published in high-income countries, including very few Asian or African studies. We therefore set out to scope the research literature to determine the extent and type of studies concerning WMI for patients/consumers across these two continents. We sought empirical studies published between January 2004 and December 2019, conducted in any Asian or African country, as defined by the United Nations, in English or with an English abstract. The majority of the 923 papers identified were from high-income countries. We retained 26 papers from Africa and 99 from Asia. Most African studies (n = 20) involved patients in the development of PILs, in the assessment of the effectiveness of PILs or in surveys. In contrast, the highest proportion of Asian studies concerned the content of WMI (n = 42). WMI is desired, but needs to be in local languages, and there needs to be more use made of pre-tested pictograms. Existing WMI frequently does not meet local regulatory requirements, particularly locally manufactured products. A number of studies reported potentially positive impacts of providing WMI on knowledge and medicine use behaviours. Provision of medicine information is essential for safe use of medicines in all countries. Internationally agreed guidelines, incorporating good design principles, are needed to ensure the optimal content and design of WMI. The World Health Organization should support African and Asian regulatory bodies to share best practice in relation to WMI for patients/consumers and to develop and implement pan-continental guidelines that take into account consumer needs and preferences.

Effectiveness of pictographs in improving patient education outcomes: a systematic review

The objective of this review was to investigate process of pictograph development and the effectiveness of pictographs in patient education. We conducted searches in Medline/PubMed, CINAHL with full text, PsycInfo, ERIC and Cochrane Library with keywords: (pictograph or pictorial) AND (patient education) NOT (children or adolescent or youth or child or teenagers). After excluding manuscripts that did not meet inclusion criteria, 56 articles were included between the time of the last review on this topic (January 2008) and May 2019. There are 17 descriptive studies, 27 randomized control trial studies, 9 quasi-experimental studies and 2 unique literatures in the systematic review. Major goals of the studies are pictograph development or validation. The majority of manuscripts (n = 48) supported the approach. However, six studies did not find significant differences in the outcome. Differences in patient population, pictograph designs and author-developed outcome measurements made it difficult to compare the findings. There is a lack of evidence on validating information outcome measurements. This review demonstrated that implementing pictographs into patient education is a promising approach for better information understanding and health management. Pictographic interventions need to be carefully developed and validated with both the targeted patient population and the clinical experts.

Impact of pictograms on medication adherence: A systematic literature review

OBJECTIVE

The aim of this systematic review was to investigate the potential effect of pictograms on patient adherence to medication therapies.

METHOD

PubMed, MEDLINE, Embase, CINAHL, and CENTRAL were searched for relevant articles. Experimental studies testing the use of pictograms in patient counselling regarding medication therapy, which quantitatively measured adherence, were included.

RESULTS

Seventeen studies were identified that fulfilled our inclusion criteria. These were heterogeneous with respect to study setting, population size, and the medication regimen tested. All the studies had methodological quality limitations. The pictogram interventions differed with respect to complexity, intervention length, and the measured adherence outcome. Ten studies (58.8 %) reported a statistically significant effect, of the pictogram intervention in question, on patient adherence to medication therapies. Of these, 80 % involved populations at elevated risk for non-adherence.

CONCLUSION AND PRACTICE IMPLICATIONS

Pictograms used in combination with written and/or oral information can have a positive impact on patient populations that are highly at risk for non-adherence when counselled on the proper use of medicines.

Comprehensibility of pharmaceutical pictograms: Effect of prospective-user factors and cognitive sign design features

BACKGROUND

The people's comprehensibility regarding the meaning of internationally recommended pictograms is an important factor in the correct usage of medications.

OBJECTIVE

To investigate the relationship between the guessability of the pharmaceutical pictograms, the cognitive sign features, and prospective-user factors.

METHODS

A total of 351 Iranian people participated in this study. Two questionnaires were used to measure guessability and cognitive design features regarding the pharmaceutical pictograms. A single-sheet questionnaire was also developed to collect demographic data.

RESULTS

According to the 67% correctness criterion suggested by ISO 3864:P3, 18 pictograms were understandable by the participants. Moreover, of the five cognitive features, "semantic closeness" and "meaningfulness" had the most correlation with the guessability score. In terms of personal factors, understanding of the pictograms' meaning was negatively correlated with age, while it had no association with the occupation.

CONCLUSIONS

Some pharmaceutical pictograms developed by reliable international organizations can be used in a community only after redesigning and testing among the prospective users. The findings indicated that some pharmaceutical pictograms were not comprehensible for most participants. It is therefore expected that using a combination of pictograms with written messages and training could help in conveying the messages by pharmaceutical pictograms.

Health communication research in the Arab world: A bibliometric analysis

Objective

Health communication is a novel field in the Arab world. This study aimed to describe and characterise health communication research activity in the region.

Methods and analysis

The PubMed database was used to search for publications related to health communication from Arab states. Publications were classified according to country of origin, without limiting for date. Research activity and output were examined with respect to population and the gross domestic product (GDP) of each Arab state.

Results

A total of 66 contributions related to health communication came from the Arab countries, with the first paper published from Lebanon in 2004. Health communication-related publications constituted 0.03% of the total biomedical research contributions published by the Arab world since 2004 and 1% of the world’s health communication literature. Number of health communication contributions ranged between 0 and 12, with Lebanon producing the most output. Qatar ranked first with respect to contributions per population, whereas Lebanon ranked first with respect to contributions per GDP. Algeria, Comoros, Djibouti, Iraq, Kuwait, Libya, Mauritania, Somalia, Sudan and Yemen had nil health communication publications.

Conclusion

Recognising the barriers facing the health communication field and addressing them carefully are vital in the plan to better the Arab world’s output and contribution in the field.

A Scoping Review on How to Make Hospitals health Literate Healthcare Organizations

The concept of health literacy is increasingly being recognised as not just an individual trait, but also as a characteristic related to families, communities, and organisations providing health and social services. The aim of this study is to identify and describe, through a scoping review approach, the characteristics and the interventions that make a hospital a health literate health care organisation (HLHO), in order to develop an integrated conceptual model. We followed Arksey and O’Malley’s five-stage scoping review framework, refined with the Joanna Briggs Institute methodology, to identify the research questions, identify relevant studies, select studies, chart the data, and collate and summarize the data. Of the 1532 titles and abstracts screened, 106 were included. Few studies have explored the effect of environmental support on health professionals, and few outcomes related to staff satisfaction/perception of helpfulness have been reported. The most common types of interventions and outcomes were related to the patients. The logical framework developed can be an effective tool to define and understand priorities and related consequences, thereby helping researchers and policymakers to have a wider vision and a more homogeneous approach to health literacy and its use and promotion in healthcare organizations.

Recall of Pharmaceutical Pictograms by Older Adults

BACKGROUND

Low health literacy and high medication burden in the older adult population are contributing factors to the misunderstanding of medication instructions, leading to an increased risk of poor adherence and adverse events in this group of patients.

OBJECTIVE

To evaluate the ability of older adults to recall the meaning of 13 pharmaceutical pictograms 4 weeks after receipt of feedback on pictogram meaning.

METHODS

Older adults (aged 65 or older) were recruited from one community pharmacy in Canada. One-on-one structured interviews were conducted to assess the comprehensibility of 13 pharmaceutical pictograms from the International Pharmaceutical Federation's database of pictograms. Each participant was then told the meaning of each pictogram. Recall was assessed 4 weeks later.

RESULTS

A total of 58 participants met the inclusion criteria and agreed to participate. The number of pictograms meeting the ISO threshold for comprehensibility of symbols increased from 10 at the initial comprehensibility assessment to 13 at the recall assessment. Analysis of demographic data showed no associations between initial comprehensibility of the pictograms and age, sex, education level, or number of medications taken.

CONCLUSIONS

The results of this study indicate that after being informed of the meaning of pharmaceutical pictograms, older adults were able to recall the pictogram meanings for at least 4 weeks.

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.

Divide and conquer: improving parental understanding of health-related instructions using sequential pictorial instructions

Patient misunderstandings of healthcare-related instructions result in significant health, social and economic consequences. Pushing the boundaries of traditional academic methods may offer strategies that promote new ways to improve communication and understanding between healthcare providers, caregivers and patients. Comics can be an educational tool, offering an innovative strategy to communicate health-related information. Our study objective was to compare parents' understanding of health-related instructions (i.e. prescription labels, medical instructions and emergency situation scenarios) that were presented using two different formats-sequential pictorial instructions (SPIs) versus written text instructions (WRIs).This was a cross-sectional study to compare parents' understanding of health-related instructions for pediatric patients using structured SPIs versus WRIs. Parents (n = 359, 18-82 years old) of pediatric patients were given a card with instructions that were presented as SPIs (n = 195, 54.3%) or WRIs (n = 164, 45.7%), and then they completed a questionnaire. Total (14 questions) and grouped scores (10 questions) for parental comprehension of prescription and medical emergency instructions were significantly higher among participants viewing the SPIs than those viewing the WRIs in both English and Spanish. The mean understanding of instructions significantly increased from 6% to 12.2% when comparing the WRI versus the SPI.Our initial findings indicate that parents and caregivers of pediatric patients had significantly better understanding and recall of instructions delivered using SPIs than using WRIs.

The evaluation of pharmaceutical pictograms among elderly patients in community pharmacy settings - a multicenter pilot study

INTRODUCTION

The search for new ways to optimize the use of medications by patients has led the pharmaceutical community to promote the idea of introducing pictograms into routine practice. The main intention of pictograms is to ease patient adherence and to reduce potential risks or errors associated with the use of medications.

PURPOSE

To evaluate a series of pharmaceutical pictograms for patient comprehension.

PATIENTS AND METHODS

The study was conducted in community pharmacies within a European Union country that belongs to the professional research network. Structured interviews were used to evaluate the pictograms for patient comprehension. This consisted of an assessment of the following: the transparency and translucency of the pictograms, health literacy, and pictogram recall. Participants were also given the opportunity to provide feedback on how to improve the pictograms. The primary endpoint was pictogram comprehension. Secondary outcomes included recall of the pictograms and pictogram translucency.

RESULTS

The study included 68 patients with whom face-to-face interviews were performed. Low transparency results (≤25%) and extensive patient feedback in initial interviews led to the withdrawal of certain pictograms (n=15) from the evaluation. Among the pictograms included in the final stage of our research, 22 pictograms (62.8%) obtained an acceptable transparency level ≥66%. All pictograms passed the short-term recall test with positive results.

CONCLUSION

A majority of the designed and modified pictograms reached satisfactory guess-ability scores. Feedback from patients enabled modification of the pictograms and proved that patients have an important voice in the discussion regarding the design of additional pictograms.

Comprehensibility of selected United States Pharmacopeia pictograms by illiterate and literate Farsi speakers: The first experience in Iran - Part II

Background:

Conveying information to patients on how to use medications at the dispensing sessions and retention of this information by the patients is essential to the good pharmaceutical care. The aim of our study was to examine the comprehensibility of the selected three potentially usable pictograms by five groups of subjects who had different levels of literacy in both before and after mini educational sessions.

Materials and Methods:

Nine experienced pharmacists selected three potentially usable pictograms in Isfahan pharmacies: Pictograms D through F representing respectively: “do not take medication during pregnancy,” “keep medication in the refrigerator,” and “take medication with plenty of water.” Then, graduate students of two major universities (Groups 1 and 2), low-literate and illiterate individuals (Groups 3 and 4), and walk – in patients in the pharmacies affiliated to the Isfahan School of Pharmacy (Group 5) were asked about the comprehensibility of these pictograms before and after mini-education sessions. The American National Standard Institute and International Organization for Standardization standards were used for comparisons.

Results:

In the pre-follow-up period, D and E pictograms were most understandable (87.4%, 87.2%). In the post-follow-up, E and D pictograms were understood most (98.0%, 95.3%), followed by F (92.9%). Among the improvements measured in post-follow-up, pictogram F showed the biggest improvement (P = 0.0).

Conclusion:

Pictograms depicting the use of medications during pregnancy (D) and storing medication in the refrigerator (E) was easier to understand by our study population. The groups with the high level of literacy interpreted the pictograms better than those with lower levels of literacy.

Readability and Comprehensibility of Patient Information Leaflets for Antidiabetic Medications in Qatar

Background:The readability and comprehensibility of the patient information leaflets (PILs) provided with antidiabetic medications are of questionable standards; this issue negatively affects adherence to drug therapy, especially in patients with limited literacy skills. Objective: To evaluate the readability and comprehensibility of PILs supplied with medications used for the treatment of type 2 diabetes mellitus in Qatar. Methods: All PILs of the antidiabetic medications in Qatar were evaluated using the Flesch Reading Ease (FRE) score for readability. The Flesch-Kincaid Grade Level, Gunning-Fog Index, and SMOG Grading were used to estimate the comprehensibility of PILs in terms of school grade levels. Results: A total of 45 PILs were evaluated: 32 (71.1%) PILs of brand-name products and 13 (28.9%) for generics. Nine (20%) of the PILs were in English only; 8 (17.8%) were in English, Arabic, and French; and 28 (62.2%) were in English and Arabic. The mean FRE score was 37.71 (±15.85), and the most readable PIL had FRE score of 62. The mean scores for the comprehensibility evaluations were 10.96 (±2.67), 15.02 (±2.52), and 11.41 (±1.6) for the Flesch-Kincaid Grade Level, Gunning-Fog Index, and SMOG Grading, respectively. The most commonly used antidiabetic medication was metformin with 1372.9 (±552.9) as PILs' mean number of words. Conclusion: Only 2.2% of PILs had acceptable readability scores. All PILs could be comprehended by at least an 11th grade student, which exceeds the recommended grade level for health-related materials. Approximately 20% of these PILs were in English only and were not readable by most patients.

Using Text Reminder to Improve Childhood Immunization Adherence in the Philippines

A comparative descriptive study was conducted to determine the effectiveness of text messages with pictures compared with plain text messages or verbal reminders in improving measles, mumps, and rubella immunization compliance in the rural areas of the Philippines. We found that text messaging with or without pictures is a feasible and useful tool in measles, mumps, rubella immunization compliance for childhood immunization. Texting with pictures (n = 23), however, was no more effective than plain text messaging (n = 19) or verbal reminder (n = 17) in improving measles, mumps, and rubella immunization compliance. Compared with parents who received verbal reminders alone, either type of text reminders was linked to parents bringing their child for measles, mumps, and rubella immunization on a timelier basis, as defined by the difference between the scheduled visit and the actual visit, although this was not statistically significant. Mobile technology that uses text reminders for immunization can potentially improve the communication process between parent, the public health nurse, and healthcare provider. Future studies can explore the application of plain text messages or text messages with pictures to improve compliance more broadly for maternal and child healthcare especially in rural areas of developing countries and may be a helpful tool for health promotion for this population.

Pharmacists and patients feedback on empirically designed prescription warning labels: a qualitative study

Background Recommendations call for the inclusion of both patient and provider input in the redesign of prescription labels. Pharmacist opinions on prescription warning labels are important because they are the health providers who would eventually distribute and explain the revised labels during medication counseling. They may be the first health provider to notice a patient's misunderstanding on how to safely use their prescription medications. Objectives To explore the perspectives of patients and pharmacists on five newly designed PWLs, and examine if there were similarities and differences between patients' and pharmacists' perspectives. Setting Private room in Wisconsin. Methods A descriptive study using semi-structured 60-min face-to-face individual interviews with patients and pharmacists explored patients and pharmacists' feedback on five newly designed PWLs. Patients who were 18 years and older, spoke English, and took a prescription medication and pharmacists who filled prescriptions in an ambulatory setting participated in the study. The patient and pharmacist perspectives on the words (content), picture and color (cosmetic appearance), and placement of warning instructions on the pill bottle (convenience) was based on a label redesign framework. Qualitative content analysis was done. Main outcome measure Patient and pharmacist perspectives on the newly designed PWLs. Results Twenty-one patients and eight pharmacists practicing in an academic medical center outpatient setting (n = 5) or retail pharmacy (n = 3) participated. All patients and pharmacists wanted the PWLs positioned on the front of the pill bottle but not the side of the bottle or warning instructions embedded into the main prescription label. Other similarities included participants preferring: (1) pictures closely depicting the instructions and (2) the use of yellow highlighting on the PWL to draw attention to it. There were differences in patient and pharmacist perspectives regarding the addition of 'Warning' to the instruction on the PWL with the patient preference to include the word 'Warning'. Pharmacists thought some PWL pictures had racial stereotypes, but this feedback was never mentioned by patients. Conclusions Patients and pharmacists had different preferences for PWL design changes to improve understandability. Pharmacist preferences did not always correspond with patient preferences. However, patients and pharmacists generally agreed on the preferred location of the PWL on the pill bottle and the use of color for drawing patients' attention.

Addressing low health literacy with "Talking Pill Bottles": A pilot study in a community pharmacy setting

OBJECTIVES

To test the effect of "Talking Pill Bottles" on medication self-efficacy, knowledge, adherence, and blood pressure readings among hypertensive patients with low health literacy and to assess patients' acceptance of this innovation.

DESIGN

Longitudinal nonblinded randomized trial with standard treatment and intervention arms.

SETTING AND PARTICIPANTS

Two community pharmacies serving an ethnically diverse population in the Pacific Northwest. Participants were consented patients with antihypertension prescriptions who screened positive for low health literacy based on the Test of Functional Health Literacy Short Form. Participants in the intervention arm received antihypertensive medications and recordings of pharmacists' counseling in Talking Pill Bottles at baseline. Control arm participants received antihypertensive medications and usual care instructions.

MAIN OUTCOME MEASURES

Comparison and score changes between baseline and day 90 for medication knowledge test, Self-Efficacy for Appropriate Medication Use Scale (SEAMS), Morisky Medication Adherence Scale (MMAS-8), blood pressure, and responses to semistructured exit interviews and Technology Acceptance Model surveys.

RESULTS

Of 871 patients screened for health literacy, 134 eligible participants were enrolled in the trial. The sample was elderly, ethnically diverse, of low income, and experienced regarding hypertension and medication history. In both arms, we found high baseline scores in medication knowledge test, SEAMS, and MMAS-8 and minimal changes in these measures over the 90-day study period. Blood pressure decreased significantly in the intervention arm. Acceptability scores for the Talking Pill Bottle technology were high.

CONCLUSION

Our results suggest that providing audio-assisted medication instructions in Talking Pill Bottles positively affected blood pressure control and was well accepted by patients with low health literacy. Further research involving newly diagnosed patients is needed to mitigate possible ceiling effects that we observed in an experienced population.

Redesigning pictographs for patients with low health literacy and establishing preliminary steps for delivery via smart phones

BACKGROUND

Pictographs (or pictograms) have been widely utilized to convey medication related messages and to address nonadherence among patients with low health literacy. Yet, patients do not always interpret the intended messages on commonly used pictographs correctly and there are questions how they may be delivered on mobile devices.

OBJECTIVE

Our objectives are to refine a set of pictographs to use as medication reminders and to establish preliminary steps for delivery via smart phones.

METHODS

Card sorting was used to identify existing pictographs that focus group members found "not easy" to understand. Participants then explored improvements to these pictographs while iterations were sketched in real-time by a graphic artist. Feedback was also solicited on how selected pictographs might be delivered via smart phones in a sequential reminder message. The study was conducted at a community learning center that provides literacy services to underserved populations in Seattle, WA. Participants aged 18 years and older who met the criteria for low health literacy using S-TOFHLA were recruited.

RESULTS

Among the 45 participants screened for health literacy, 29 were eligible and consented to participate. Across four focus group sessions, participants examined 91 commonly used pictographs, 20 of these were ultimately refined to improve comprehensibility using participatory design approaches. All participants in the fifth focus group owned and used cell phones and provided feedback on preferred sequencing of pictographs to represent medication messages.

CONCLUSION

Low literacy adults found a substantial number of common medication label pictographs difficult to understand. Participative design processes helped generate new pictographs, as well as feedback on the sequencing of messages on cell phones, that may be evaluated in future research.

Optimising adherence to childhood pneumonia treatment: the design and development of patient instructions and a job aid for amoxicillin dispersible tablets

INTRODUCTION

Pneumonia is the leading cause of death from infection in children worldwide. Despite global treatment recommendations that call for children with pneumonia to receive amoxicillin dispersible tablets, only one-third of children with pneumonia receive any antibiotics and many do not complete the full course of treatment. Poor adherence to antibiotics may be driven in part by a lack of user-friendly treatment instructions.

OBJECTIVE

In order to optimise childhood pneumonia treatment adherence at the community level, we developed a user-friendly product presentation for caregivers and a job aid for healthcare providers (HCPs). This paper aims to document the development process and offers a model for future health communication tools.

METHODS

We employed an iterative design process that included document review, key stakeholder interviews, engagement with a graphic designer and pre-testing design concepts among target users in India and Kenya. The consolidated criteria for reporting qualitative research were used in the description of results.

RESULTS

Though resources for pneumonia treatment are available in some countries, their content is incomplete and inconsistent with global recommendations. Document review and stakeholder interviews provided the information necessary to convey to caregivers and recommendations for how to present this information. Target users in India and Kenya confirmed the need to support better treatment adherence, recommended specific modifications to design concepts and suggested the development of a companion job aid. There was a consensus among caregivers and HCPs that these tools would be helpful and improve adherence behaviours.

CONCLUSIONS

The development of user-friendly instructions for medications for use in low-resource settings is a critically important but time-intensive and resource-intensive process that should involve engagement with target audiences.
