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

Methodology of an approach for modifying pictograms showing medication side effects or indication

BACKGROUND

Pictograms may improve user-friendliness and comprehension of written or verbal health information. This paper describes a method to modify pictograms to improve their visual clarity, appeal and overall interpretive complexity in order to reduce the cognitive load on the viewer during comprehension.

METHODOLOGY

Nine pictograms previously tested for comprehension were selected for modification. In phase 1, two participatory design workshops were conducted with (a) three limited literacy, first-language isiXhosa-speaking participants and (b) four university students. Opinions and ideas for improving interpretation were discussed. In phase 2, revised visuals were generated by the graphic artist and subsequently modified in an intensive, multistage, iterative process.

RESULTS

As no guidelines for pictogram modification exist, a modification schema was developed based on the process described in this study. Adopting a participatory approach combined with a systematic, intensive modification process enabled the opinions and preferences of the end-users to be heard, ensuring cultural relevance and contextual familiarity of the final product. Careful scrutiny of all individual visual elements of each pictogram, considerations of space, and thickness of lines all contributed to improving the legibility of visuals.

CONCLUSIONS

The methodology for designing and modifying existing pictograms using a participatory process resulted in nine final pictograms that were approved by all design team members and considered good candidates for subsequent comprehension testing. The methodological schema presented in this paper provides guidance to researchers intending to design or modify pictograms.

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.

Well-designed medical pictograms accelerate search

Two types of newly designed pharmaceutical pictograms (with and without context) were compared with an existing type of certified pictograms regarding their search efficiency. Each of the 30 participants had to search a total of 1'090 "fictitious" medical shelves for a certain box defined by the amount and type of medical instructions given (memory size) and presented among a variable number of other boxes (set size). The boxes contained the different types of pictograms mentioned above. Calculated factorial analyses on reaction time data, among others, showed that the two newly designed pictogram types make search more efficient compared to existing types of pictograms (i.e., flatter reaction time x set size slopes). Furthermore, regardless of the type of pictogram, this set size effect became more pronounced with larger memory sizes. Overall, the newly designed pictograms need fewer attentional resources and therefore might help to increase patient adherence.

International consensus statement on allergy and rhinology: Olfaction

BACKGROUND

The literature regarding clinical olfaction, olfactory loss, and olfactory dysfunction has expanded rapidly over the past two decades, with an exponential rise in the past year. There is substantial variability in the quality of this literature and a need to consolidate and critically review the evidence. It is with that aim that we have gathered experts from around the world to produce this International Consensus on Allergy and Rhinology: Olfaction (ICAR:O).

METHODS

Using previously described methodology, specific topics were developed relating to olfaction. Each topic was assigned a literature review, evidence-based review, or evidence-based review with recommendations format as dictated by available evidence and scope within the ICAR:O document. Following iterative reviews of each topic, the ICAR:O document was integrated and reviewed by all authors for final consensus.

RESULTS

The ICAR:O document reviews nearly 100 separate topics within the realm of olfaction, including diagnosis, epidemiology, disease burden, diagnosis, testing, etiology, treatment, and associated pathologies.

CONCLUSION

This critical review of the existing clinical olfaction literature provides much needed insight and clarity into the evaluation, diagnosis, and treatment of patients with olfactory dysfunction, while also clearly delineating gaps in our knowledge and evidence base that we should investigate further.

Sexual health communication in COPD: The role, contents and design of patient information leaflets

Understanding need for support and information among people with COPD is important for the delivery of patient-centred care. Especially regarding intimacy matters, many people wish to remain sexually active but may be struggling to find out how, as information and communication regarding sexual health is scarce. This is especially true when it comes to people with chronic obstructive pulmonary disease (COPD). The present review seeks to provide an overview of the role, contents and design of patient information leaflets (PILs) and discuss their application in sexual health communication for COPD. Based on the literature, a number of key points in the design of high-quality PILs are suggested, and important areas for the improvement of patients-clinician communication are highlighted. While PILs is a commonly used format to provide information in healthcare, other formats, e.g. video and podcasts, could be explored. Prioritizing the development of material to support communication in the future is necessary to address the needs of both patients and caregivers and to support clinicians in initiating conversations about sexual health and intimacy matters.

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.

Developing Infographics to Facilitate HIV-Related Patient-Provider Communication in a Limited-Resource Setting

BACKGROUND

Productive patient-provider communication is a recognized component of high-quality health care that leads to better health outcomes. Well-designed infographics can facilitate effective communication, especially when culture, language, or literacy differences are present.

OBJECTIVES

This study aimed to rigorously develop infographics to improve human immunodeficiency virus (HIV)-related patient-provider communication in a limited-resource setting. A secondary purpose was to establish through participant feedback that infographics convey intended meaning in this clinical and cultural context.

METHODS

We adapted a participatory design methodology, developed in a high-resource setting, for use in the Dominican Republic. Initially, content to include was established using a data-triangulation method. Then, infographics were iteratively generated and refined during five phases of design sessions with three stakeholder groups: (1) 25 persons living with HIV, (2) 8 health care providers, and (3) 5 domain experts. Suggestions for improvement were incorporated between design sessions and questions to confirm interpretability of infographics were included at the end of each session.

RESULTS

Each participant group focused on different aspects of infographic designs. Providers drew on past experiences with patients and offered clinically and contextually relevant recommendations of symbols and images to include. Domain experts focused on technical design considerations and interpretations of infographics. While it was difficult for patient participants to provide concrete suggestions, they provided feedback on the meaning of infographics and responded clearly to direct questions regarding possible changes. Fifteen final infographics were developed and all participant groups qualitatively confirmed that they displayed the intended content in a culturally appropriate and clinically meaningful way.

CONCLUSION

Incorporating perspectives from various stakeholders led to the evolution of designs over time and generated design recommendations that will be useful to others creating infographics for use in similar populations. Next steps are to assess the feasibility of using infographics to improve clinical communication and patient outcomes.

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.

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.

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

PRACTICE IMPLICATIONS

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