Development of written information for antiretroviral therapy: comprehension in a Tanzanian population

Comprehensibility of South African pictograms by sub-Saharan African prospective-users

OBJECTIVES

This work aimed to explore the validity of South African pictograms to be comprehended by sub-Saharan migrant populations in Spain.

METHODS

A quantitative cross-sectional study was carried out. A voluntary survey was conducted among a population ≥ 18 years of age in a Temporary Stay Centre for Immigrants located in Spain, in June 2022. The form included a culturally and linguistically validated version of the Health Literacy questionnaire (HLS-EU-Q16), a brief questionnaire of sociodemographic variables and 10 South African pictograms selected to assess the comprehension. According to the International Organization for Standardization, a pictogram must receive 66.70% correct answers to be acceptable. Mann-Whitney U or Kruskal-Wallis tests were used to assess differences between group variables. Statistical significance was set at P < 0.05.

RESULTS

55 sub-Saharan migrants who newly arrived in Europe voluntarily agreed to participate. None of the pictograms evaluated met the validity criterion. For the selected pictograms, the range of correct answers was between 52.50% and 20.00%. Neither sociodemographic variables nor Health Literacy level were significantly associated with pictogram comprehensibility.

CONCLUSION

New culturally sensitive pictograms that are easily comprehended by sub-Saharan African population are needed.

PRACTICE IMPLICATIONS

These results may serve as a starting point for future studies that aim to create and evaluate new pictograms or create new culturally adapted versions of existing pictograms involving the target population.

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.

Factors that Facilitate and Hinder the Comprehension of Patient Information Leaflets (PILs): A Brief Scoping Review

Introduction: Patient information leaflets (PILs) of medicinal products are informative documents that accompany medicines and explain their components, modes of use, interactions with other medicines, and other relevant issues. When patients do not adequately understand the information in the leaflets, they may engage in behaviors that affect their health (e.g., self-medication). Objective: To identify patient-related factors and characteristics of PILs that can promote cognitive, emotional, and behavioral changes that lead to appropriate drug use practices. Additionally, we aimed to determine strategies that could be implemented to design leaflets that convey adequate information and are easier to understand. Method and Results: We evaluated scientific articles published in databases and containing information on PILs suitability to be used in a patient population. A total of 51 articles were selected as the sample. Certain leaflet factors that favored or hindered understanding were identified (e.g., format in which the leaflets are presented, their structure, their adaptation to the sociodemographic and linguistic characteristics of the population, their wording…). Similarly, we also identified patient factors, such as previous experience taking the drugs referred to in the leaflet; the type of emotions experienced when reading the leaflets; the emphasis on the adverse effects of the medications; sociodemographic variables (i.e., age or educational level); and degree of interest in their own healthcare. Conclusion: Patient and leaflet factors influence the comprehension of information in the PIL; hence, emphasis should be placed on these factors to increase treatment and medication adherence and to reduce health-risk behaviors.

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.

Survey of healthcare professionals' practices, expectations, and attitudes towards provision of patient information leaflets in Thailand

Background Patient information leaflets are an important source of medicine information for patients. In Thailand, there is a lack of studies exploring activities of healthcare professionals and their attitudes towards provision of patient information leaflets. Objectives This study aimed to survey healthcare professionals' practices on provision of medicine information, expectations of, attitudes towards provision of patient information leaflets and factors influencing these. Setting Two university hospitals in Thailand. Methods A self-completion questionnaire was distributed to chiefs of departments for further distribution to staff. A stratified sample of physicians and nurses was invited, while all pharmacists were invited to ensure sufficient numbers for comparison. Main outcome measure Healthcare professionals' practices on provision of medicine information, expectations of, attitudes towards provision of patient information leaflets. Results Of the total 981 healthcare professionals invited, 493 responded (50.3% response rate). The number of respondents aware of patient information leaflets was 270 (57.6%). Of these, only 44.4% had ever given patient information leaflets to patients. Pharmacists provided patient information leaflets more frequently than other healthcare professionals. The expectation for patient information leaflets to be available was high; mean score 7.9 ± 2.31 of possible 10. Most respondents had positive attitudes towards providing patient information leaflets to patients (58.2%). Respondents who were aware of patient information leaflets availability were more likely to have a positive attitude (OR 0.543, p = 0.002). Level of education, time spent in direct care and being aware of patient information leaflets were factors associated with healthcare professionals' attitudes. Conclusion Limited number of healthcare professionals had provided patient information leaflets to patients but most had positive attitudes regarding the usefulness of patient information leaflets for patients. Increased availability and use of patient information leaflets should be promoted.

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.

Simple, illustrated medicines information improves ARV knowledge and patient self-efficacy in limited literacy South African HIV patients

Few studies have investigated antiretroviral (ARV) knowledge and self-efficacy in limited literacy patients. Using a randomized controlled study design, we investigated the influence of a simple pre-tested patient information leaflet (PIL) containing both text and illustrations on HIV- and ARV-related knowledge and on self-efficacy over six months in a limited literacy African population. The recruited patients were randomly allocated to either control (standard care) or intervention group (standard care plus illustrated PIL). HIV and medicines-related knowledge was evaluated with a 22-question test at baseline, one, three, and six months. Self-efficacy was assessed using a modified version of the HIV Treatment Adherence Self-Efficacy Scale. Two-thirds of the patients were female, mean age was 39.0 ± 9.6 years and mean education was 7.3 ± 2.8 years. Patients who received the PIL showed a significant knowledge increase over the six-month period (62.0-94.4%), with improvement at each subsequent interview whereas the control group showed no improvement. At baseline, side effect knowledge was the lowest (50-56%) but increased in the intervention group to 92%. Similarly, other medicine-related knowledge at baseline (57-67%) improved significantly (93%) and was sustained over six months. Cohen's d values post-baseline ranged between 1.36 and 2.18, indicating a large intervention effect. Self-efficacy improved significantly over six months in intervention but not control patients. At baseline, patients with ≤ 3 years of education had lower knowledge and self-efficacy but this was not observed post-intervention, which we attribute to the PIL mitigating the effect of limited education. Knowledge and self-efficacy were significantly correlated in the intervention group. In conclusion, a low-cost intervention of a well-designed, pre-tested, simple, illustrated PIL significantly increased both ARV knowledge and self-efficacy in HIV patients with limited education.

Understanding of pictograms from the United States Pharmacopeia Dispensing Information (USP-DI) among elderly Brazilians

OBJECTIVE

To assess the understanding and cultural acceptability of the United States Pharmacopeia Dispensing Information (USP-DI) in a group of elderly Brazilians.

METHODS

The study participants were individuals between 60 and 90 years old, of both sexes, with different levels of education and income. Fifteen of 81 pictograms from the USP-DI were presented to the elderly subjects, individually, without subtitles and in random order, so that the participants' understanding of the pictograms could be evaluated.

RESULTS

The study included 116 participants. Only one of the selected pictograms reached the comprehension criterion established by the International Organization for Standardization 3864. With regard to the relationship between understanding and sociodemographic characteristics, age, wage income, and level of education were all found to be significantly associated with participants' understanding of some of the pictograms.

CONCLUSION

Most of the USP-DI pictograms evaluated were not well understood by the elderly Brazilians. This finding indicates that such pictograms need to be culturally adapted for the Brazilian context if they are to serve their purpose effectively in this country.

An illustrated leaflet containing antiretroviral information targeted for low-literate readers: development and evaluation

OBJECTIVE

To apply a dual visual/textual modal approach in developing and evaluating a medicine information leaflet with pictograms suitable for low-literate HIV/AIDS patients. To identify and recommend best practices in this type of information design.

METHODS

A simple leaflet incorporating pictograms was designed for an antiretroviral regimen. Cognitive testing for understanding was conducted in 39 low-literate, South African, antiretroviral-naïve adults. Participants were required to locate and explain the information, and were questioned on their opinion of leaflet layout and contents.

RESULTS

Average understanding of the leaflet was 60%. Basic medication information was the best understood. An overall lack of knowledge of HIV/AIDS and its core concepts was found. Only half the participants considered this simple leaflet "easy" to read. All endorsed the inclusion of pictograms.

CONCLUSION

This testing method used in ARV-naïve individuals was invaluable in identifying areas needing modification before its use in patients. Text associated with pictograms was more noticeable and better understood, but only if they were closely juxtaposed.

PRACTICE IMPLICATIONS

Leaflet design should consider culture and literacy skills, be informed by learning theory and design principles, include visuals to enhance appeal and improve understanding, and involve end-users. Verbal counseling should accompany written information.

A framework for the evaluation of patient information leaflets

BACKGROUND

  The provision of patient information leaflets (PILs) is an important part of health care. PILs require evaluation, but the frameworks that are used for evaluation are largely under-informed by theory. Most evaluation to date has been based on indices of readability, yet several writers argue that readability is not enough. We propose a framework for evaluating PILs that reflect the central role of the patient perspective in communication and use methods for evaluation based on simple linguistic principles.

THE PROPOSED FRAMEWORK

  The framework has three elements that give rise to three approaches to evaluation. Each element is a necessary but not sufficient condition for effective communication. Readability (focussing on text) may be assessed using existing well-established procedures. Comprehensibility (focussing on reader and text) may be assessed using multiple-choice questions based on the lexical and semantic features of the text. Communicative effectiveness (focussing on reader) explores the relationship between the emotional, cognitive and behavioural responses of the reader and the objectives of the PIL. Suggested methods for assessment are described, based on our preliminary empirical investigations.

CONCLUSIONS

  The tripartite model of communicative effectiveness is a patient-centred framework for evaluating PILs. It may assist the field in moving beyond readability to broader indicators of the quality and appropriateness of printed information provided to patients.

Patient sources for drug information in Iran: a questionnaire-based survey

OBJECTIVES

To identify sources used by patients to obtain drug-related information and to find which portion of patients study the Patient Information Leaflet (PIL).

METHODS

A cluster random sampling was used to select 19 community pharmacies in Shiraz, Iran, from 192 pharmacies registered by Food and Drug Office of Shiraz University of Medical Sciences. Using a questionnaire, an independent assessor surveyed outpatients immediately after their prescriptions were dispensed. Results were subjected to statistical analysis.

RESULTS

Total of 671 patients were interviewed, of which 188 patients (28%) reported they received no information from pharmacists or physicians and 169 patients (25%) received their medications without prescription. Nearly half of the patients (46%) were informed on the frequency of use and dose of their medications. Very few patients (6%) were appropriately informed about the frequency of use, dosage, duration of treatment, and potential side effects, allergies and drug interactions. Patients with college education used PILs as a source of information more than those with lower education levels.

CONCLUSION

A significant portion of patients obtained medicines without a prescription. Only a few portion of patients in Shiraz received adequate drug information from their physician or pharmacist. A considerable portion of patients did not study PILs.
