Best-practices for the design and development of prescription medication information: A systematic review

Warning Labels as a Public Health Intervention: Effects and Challenges for Tobacco, Cannabis, and Opioid Medications

Warning labels help consumers understand product risks, enabling informed decisions. Since the 1966 introduction of cigarette warning labels in the United States, research has determined the most effective message content (health effects information) and format (brand-free packaging with pictures). However, new challenges have emerged. This article reviews the current state of tobacco warning labels in the United States, where legal battles have stalled pictorial cigarette warnings and new products such as electronic cigarettes and synthetic nicotine products pose unknown health risks. This article describes the emerging research on cannabis warnings; as more places legalize recreational cannabis, they are adopting lessons from tobacco warnings. However, its uncertain legal status and widespread underestimation of harms impede strict warning standards. The article also reviews opioid medication warning labels, suggesting that lessons from tobacco could help in the development of effective and culturally appropriate FDA-compliant opioid warning labels that promote safe medication use and increased co-dispensing of naloxone.

Dermatology Self-Medication in Nursing Students and Professionals: A Multicentre Study

Current evidence shows that the prevalence of self-medication in healthcare professionals and their students is troublingly high despite them knowing the risks involved. There is limited research on self-medication in dermatology, and there are even fewer studies on this practice among nurses and nursing students, despite the potential mucocutaneous health problems that may affect them. The aims of our study were to examine the prevalence of self-medication mainly in the field of dermatology among nurses and nursing students as well as to explore if age or years of professional/academic practice influenced such behaviour. This multicentre cross-sectional study was conducted in 2021. In total, 120 nurses from the University Hospital of Pontevedra and 303 nursing students from the Universities of Vigo and Santiago de Compostela (N-W Spain) participated in this study (n = 423). An ad hoc questionnaire was used to evaluate self-medication decision-making. Self-medication for dermatological diseases was reported by 58.39% (n = 247) of participants. Among our respondents, 44.44% of nurses and 42.68% of students would recommend treatment for skin diseases to a third party. We found a higher prevalence of medication without prescription in nurses than in students (p < 0.001). More experience (p = 0.01) and older age (p < 0.001) were associated with more self-medication in the case of nurses and students, respectively. The prevalence of self-medication and treatment recommendation to a third party are cause for concern. Identifying these situations and associated factors may help to implement evidence-based strategies and education.

Evaluation of the design and structure of electronic medication labels to improve patient health knowledge and safety: a systematic review

INTRODUCTION

Patient misunderstanding of instructions on medication labels is a common cause of medication errors and can result in ineffective treatment. One way to better improve patient comprehension of medication labels is by optimizing the content and display of the information.

OBJECTIVES

To review comparative studies that have evaluated the design of a medication label to improve patient knowledge or safety.

METHODS

Studies were selected from systematic computerized literature searches performed in PubMed, Embase (Elsevier), Cochrane Central (EBSCO), Cumulative Index to Nursing and Allied Health Literature-CINAHL (EBSCO), and Web of Science (Thomson Reuters). Eligible studies included comparative studies that evaluated the design of a medication label to improve patient knowledge or safety.

RESULTS

Of the 246 articles identified in the primary literature search, 14 studies were selected for data abstraction. Thirteen of these studies significantly impacted the patient understanding of medication labels. Three studies included a measure of patient safety in terms of medication adherence and dosing errors. The utilization of patient-centered language, pictograms/graphics, color/white space, or font optimization was seen to have the most impact on patient comprehension.

CONCLUSION

It is essential to present medication information in an optimal manner for patients. This can be done by standardizing the content, display, and format of medication labels to improve understanding and medication usage. Evidence-based design principles can, therefore, be used to facilitate the standardization of the structure of label content for both print and electronic devices. However, more research needs to be done on validating the implications of label content display to measure its impact on patient safety.

Barriers and enablers to deprescribing of older adults and their caregivers: a systematic review and meta-synthesis

PURPOSE

The primary objective of this study was to identify the barriers and enablers to deprescribing from the viewpoint of community-dwelling older adults and their caregivers.

METHODS

This meta-synthesis included a systematic review of the literature and an inductive thematic synthesis. Medline and EMBASE were searched for studies that qualitatively explored the perspectives of older adults or their caregivers on deprescribing. Studies had to use qualitative methodologies and include community-dwelling adults (or their caregivers) aged 60 years or older who were taking one or more chronic medications. The quality of studies was assessed using the CASP tool.

RESULTS

Fourteen studies were included in the meta-synthesis. All studies included older adults, and 3 included caregivers or companions. Four barriers were identified: favorable perceptions of medications, fear of medication discontinuation, the complexity of the healthcare system and discouragement from healthcare professionals; and seven enablers were identified: medication safety concerns, patient autonomy and confidence, education, follow-up, deprescribing strategies, relationships with physicians, and patient-perceived benefits of deprescribing.

CONCLUSION

Multiple barriers and enablers to deprescribing exist within the older adult population. Health system complexity and direct discouragement from healthcare providers were barriers uniquely identified in the older adult population. This population would benefit from interventions to increase their medication literacy, confidence, and autonomy in the deprescribing journey.

Older adult patient preferences for the content and format of prescription medication labels - A best-worst scaling and discrete choice experiment study

BACKGROUND

Patient preferences for the content and format of prescription medication labels (PMLs, i.e., sticker labels placed on medication bottles/packets at dispensing) have been extensively studied. However, accommodating all preferences on PMLs is impractical due to space limitations. Understanding how patients prioritise the content and format attributes of PMLs can inform improvements while working within PML space constraints.

OBJECTIVES

We aimed to (1) identify a ranking of medication-related content attributes to be prioritised on PMLs using best-worst scaling (BWS), and (2) determine the relative importance of format attributes when incorporated onto PMLs using discrete choice experiment (DCE), from the perspective of older adult patients in Singapore.

METHODS

Attributes were informed by our prior qualitative study and PML best practice guidelines. For the BWS component, the assessed content attributes were indication, precautions, interaction or paired medicines, food instructions, side effects, expiry date, and missed dose action, all of which are currently not legally mandated on PMLs in Singapore. A BWS object case was used to rank the content attributes. For the DCE component, in a series of questions, participants were asked to choose between two PML options each time, that varied in the presentation of dosage-frequency instructions, font size, presentation of dosage, presentation of precautions, and font colour of precautions. A mixed logit model estimated the relative utilities of format attribute levels, enabling the calculation of importance scores of the format attributes.

RESULTS

The study recruited 280 participants (mean age: 68.8 ± 5.4 years). The three most-preferred content attributes were indication, precautions and interaction or paired medicines. The top three format preferences were tabular style presentation of dosage-frequency instructions, large font size and precautions in red colour.

CONCLUSIONS

Healthcare institutions should consider improving their PMLs based on the leading content and format preferences voiced by older adult patients. The methodology adopted in the study can also be used for aligning the content and format of other patient education materials with patient preferences.

Impact of patient-centered prescription medication labels on adherence in community pharmacy

BACKGROUND

Prescription medication labels are often constructed in a manner which hinders safe and appropriate use of medicines. The United States Pharmacopeia released voluntary standards to revise medication labels in an effort to support patients' understanding and improve medication use.

OBJECTIVE

To examine the impact of label changes on medication adherence before and after pharmacy implementation of the United States Pharmacopeia patient-centered prescription medication label standards.

METHODS

This study used a retrospective pre-post cohort design. Prescription fill claims data were obtained from a community health plan serving Medicaid patients for 1 independent community pharmacy organization across 8 retail pharmacy sites. We calculated medication possession ratios (MPR) and proportion of days covered (PDC) for medications used for contraception, asthma, hypertension, and depression from 15 months before to 13 months after implementation of the label changes.

RESULTS

Findings showed significant increases in mean MPR for asthma controller (increased by 0.111 [t = 0.290, P<0.0001]), antihypertensives (increased by 0.062 [t = 0.146, P < 0.0002]), and contraceptives medications (increased 0.133 [t = 0.209, P < 0.0001]) from preintervention to postintervention periods. Results also revealed increases in mean PDC for asthma controllers (increased by 0.193 [t = 0.267, P < 0.0001]), antihypertensives (increased by 0.067 [t = 0.175, P = 0.049]), and contraceptives (increased by 0.111 [t = 0.208, P < 0.0119]) from preintervention to postintervention periods.

CONCLUSION

We report an association between a change to more patient-centered prescription medication labels and increased medication adherence based on MPR and PDC among Medicaid recipients.

The usage pattern of patients' drug information leaflet for oral non-prescription drugs among university students in the United Arab Emirates: cross-sectional study

Background

Very few extensive studies have measured the prevalence and usage pattern of drug information leaflet (DIL) for oral non-prescription drugs (ONPDs) or identified the associated risk factors for not reading DIL among university students in the UAE.

Objective

The current study aimed to estimate the prevalence of the usage pattern of DIL for ONPDs, and delineate the associated risk factors for not reading the DIL among university students.

Methods

A cross-sectional survey-based multistage sampling technique conducted among 2875 students at three major universities in UAE. The self-administered validated questionnaire was constructed and developed based on Andersen's behavioral model. Binomial logistic regression performed to ascertain the effects of 25 potential predictors on the likelihood that participants not reading (discarded) the DIL after reading them. The primary outcome measure was reading (discarding without reading) the DIL, and the associated behaviours.

Results

2875 university students were eligible to participate in the study, but only 2519 students agreed to participate, indicating an 88% of intent participation. However, only 2,355 (81.9%) students completed the questionnaire. 1348 respondents reported using NPD (response rate 46.9%) during the past three months before conducting the study, which comprised the sample analysis (1307 were excluded). More than three-quarters of them read the DIL (always or often) at the first use (1049 of 1348, 77.8%). Approximately a quarter of those who read the DIL reported that they discarded them after reading (24.1%). The survey has identified four risk factors for not reading the DIL: those who get the drug information from physicians or pharmacists had lower odds of discarding the DIL (odds ration [OR] = 0.491, 95% confidence interval [CI]: 0.273-0.884, p value< 0.05). Medical students had lower odds of discarding the DIL (OR = 0.598, 95% CI: 0.412-0.868, p value< 0.05). Those participants who believe that NPDs are as effective as prescription drugs had lower odds of discarding the DIL (OR = 0.342, 95% CI: 0.123-0.948, p value< 0.05). Participants who use more than one NPD to treat a single symptom a day have higher odds of discarding the DIL (OR = 1.625, 95% CI: 1.122 -2.355, p value< 0.05).

Conclusion

The prevalence of drug usage pattern in this population was 57.5% as 1348 subjects reported using NPD during the past 90 days before conducting the study. We have identified four risk factors for not reading the DIL, those who get the drug information from physicians or pharmacists, medical students, those respondents who believe that NPDs were as effective as prescription drugs, and respondents self-treating a single symptom with more than one NPD. It was evident from the findings that usage pattern of NPD for DIL varied among the students, with no specific pattern dominating.

Verbal Descriptors of the Frequency of Side Effects: Implementation of EMA Recommendations in Patient Information Leaflets in Poland

Background

The European Medicines Agency (EMA) recommends a description of drug side effects based on the frequency format and the associated verbal description. Although the recommendations refer to English-speaking countries, in several non-English speaking states, official authorities have accepted the proposed recommendations on how the patient information leaflets should be designed for descriptions of side effect frequencies. The aim of the study was to examine how manufacturers of authorized medicines in Poland implement the EMA recommendations regarding the verbal descriptors of the frequency of side effects.

Methods

A qualitative study. As a first step, we identified which of the 150 pharmaceutical companies operating in Poland had the largest market share. Then, five manufacturers were selected at random from the list of the top fifteen drug manufacturers in Poland by market share of the pharmaceutical sector. Lists of medicinal products authorized for marketing in Poland were downloaded from manufacturers’ websites, and then five products from each manufacturer were selected based on random sampling. The study included only prescription medicines and excluded over-the-counter medicines and dietary supplements from the sample. Subsequently, for each of the 25 drugs relevant patient information leaflets were obtained from the manufacturers’ websites. We evaluated how information on the frequency of side effects was provided in each leaflet, including the use of EU-recommended terms (verbal descriptors such as "very common," "common," "uncommon," "rare," "very rare") and additional notes explaining their meanings.

Results

For all manufacturers, word labels of the frequencies of side effects selected for the study were the same but the additional notes explaining their meanings were different. There were various explanations of how to understand verbal descriptors of the frequency of side effects not only across different manufacturers but also across different medicines from one manufacturer.

Conclusions

There is no single standard in the Polish pharmaceutical industry for implementing the EMA recommendations into the written information about the frequency of side effects. The observed differences for an explanation of how to understand a given verbal term do not favor a uniform interpretation of the verbal frequency labels meaning by patients.

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.

An mHealth App to Support Fertility Patients Navigating the World of Infertility (Infotility): Development and Usability Study

Background

The experience of infertility and its treatment engenders considerable stress and is often described as an emotional rollercoaster. A mobile health (mHealth) app may be a novel solution to address the psychoeducational and psychosocial support needs of fertility patients because of its potential to reduce stress and increase patient empowerment. There are a few fertility-related apps that provide information and support to both men and women undergoing fertility treatment; however, none have documented their development and evaluation process.

Objective

This study aims to describe the development and evaluation process of a bilingual mHealth app, Infotility, designed to meet the psychoeducational and psychosocial support needs of men and women undergoing fertility treatment.

Methods

To develop the Infotility app, we adhered to the Medical Research Council guidelines for the development and evaluation of complex interventions. First, we conducted literature reviews and needs assessment surveys of fertility patients and health care providers who informed the content and design of the app. Second, we tested the intervention with a small group of end users who provided feedback on the design and appropriateness of the app’s content. Third, we evaluated the uptake and usability of the app using a pre-post study design. Finally, we updated the app’s content based on participants’ feedback and searched for partners to disseminate the app to the broader public.

Results

This study is the first to describe the development and evaluation process of an mHealth app for men and women undergoing fertility treatment. The app met its goal in providing fertility patients with a clinician-approved, portable resource for reliable information about medical and psychosocial aspects of infertility and its treatments and a confidential peer support forum monitored by trained peer supporters. Participants rated the engagement, functionality, information, and esthetics of the app positively, with an overall app quality mean score of 3.75 (SD 0.53) and a star rating of 3.43 (SD 0.75), with a total possible score and star rating of 5.00.

Conclusions

By documenting the systematic development and evaluation of the mHealth app for men and women undergoing fertility treatment, this paper can facilitate the replication of the study intervention and the development of similar mHealth apps.

The Effectiveness and Value of Written Medicine Information Across Asia and Africa: Systematic Review

Reviews on the role, value, effectiveness and desirable content of written medicine information (WMI) mostly include studies from high-income countries. We reviewed studies from Africa and Asia published between January 2004 and December 2019 to determine (1) the effect of WMI on knowledge and behaviour and (2) whether patients value WMI and their preferences for WMI. We included 16 intervention studies involving almost 3500 participants and 27 surveys of patients/public totalling over 11,000 people. Both the quality of the intervention studies and the reporting quality varied. Surveys were mostly localised, many with inadequate sampling strategies, and hence, were poorly representative of wider populations. However, most included a high proportion of participants with low educational levels. Most of the intervention studies reported significant improvements in knowledge and/or adherence after provision of WMI. Many utilised specially developed WMI in local languages, enhanced by pictograms. Provision of verbal information in addition to WMI showed variable impact. The proportion of people who read WMI, used as an indicator of its value, was reported in 15 surveys, with an overall figure of 74%. The most desirable aspects of WMI reported in 12 studies were indication, side effects, dose/instructions for use, contraindications, precautions and interactions. Nine studies reported local language was desirable. The studies suggest that WMI can improve both knowledge and adherence and is highly valued by people in many countries across Africa and Asia. Mechanisms should be considered by regulatory authorities and manufacturers to facilitate the provision of leaflets in local languages using simple terminology, perhaps enhanced by pictograms.This study is registered with PROSPERO, registration number: CRD42019127001.

Developing and user testing new pharmacy label formats-A study to inform labelling standards

Background

Dispensed prescription medicine labels (prescription labels) are important information sources supporting safe and appropriate medicines use.

Objective

To develop and user test patient‐centred prescription label formats.

Methods

Five stages: developing 12 labels for four fictitious medicines of varying dosage forms; diagnostic user testing of labels (Round 1) with 40 consumers (each testing three labels); iterative label revision, and development of Round 2 labels (n = 7); user testing of labels (Round 2) with 20 consumers (each testing four labels); labelling recommendations. Evaluated labels stated the active ingredient and brand name, using various design features (eg upper case and bold). Dosing was expressed differently across labels: frequency of doses/day, approximate times of day (eg morning), explicit times (eg 7 to 9 AM), and/or explicit dosing interval. Participants’ ability to find and understand medicines information and plan a dosing schedule were assessed.

Results

Participants demonstrated satisfactory ability to find and understand the dosage for all label formats. Excluding active ingredient and dosing schedule, 14/19 labels (8/12 in Round 1; 6/7 in Round 2) met industry standard on performance. Participants’ ability to correctly identify the active ingredient varied, with clear medicine name sign‐posting enabling all participants evaluating these labels to find and understand the active ingredient. When planning a dosing schedule, doses were correctly spaced if the label stated a dosing interval, or frequency of doses/day. Two‐thirds planned appropriate dosing schedules using a dosing table.

Conclusions

Effective prescription label formatting and sign‐posting of active ingredient improved communication of information on labels, potentially supporting safe medicines use.

Patient and Public Involvement

Consumers actively contributed to the development of dispensed prescription medicine labels. Feedback from consumers following the first round was incorporated in revisions of the labels for the next round. Patient and public involvement in this study was critical to the development of readable and understandable dispensed prescription medicine labels.

Medication Handling and Storage among Pilgrims during the Hajj Mass Gathering

We aimed to investigate the knowledge and practices of Hajj pilgrims regarding medication storage and handling during the Hajj mass gathering. In this cross-sectional study, adult pilgrims from 30 countries were interviewed using a structured questionnaire during the 2019 Hajj. The study enrolled 1221 participants with a mean age of 50.8 years (SD = 12.5, range = 18-98) and male:female ratio of 1.7:1. Most pilgrims were literate, 50.4% had a university or higher education, and 38% reported at least one underlying health condition. Most pilgrims reported receiving education regarding the proper way to store their medication during Hajj, mainly from physicians (73.7%) and pharmacists (39.4%). Although 68.2% of pilgrims had good knowledge regarding medication storage and the potential effect of inappropriate storage conditions on medications and health, inadequate knowledge and poor practice were identified among some. Level of education, having an underlying health condition and receiving health education on mediation storage were independently associated with good knowledge. Most pilgrims took their medications with them during Hajj, although storage and handling of their medication also varied depending on the stages of their Hajj pilgrimage journey. Improving Hajj pilgrims' awareness and knowledge about appropriate storage and handling of their medications are beneficial in reducing the risk of associated adverse health outcomes, both during Hajj and beyond the mass gathering.

Development of salient medication reminders to facilitate information transfer during transition from inpatient to primary care: the Delphi process

OBJECTIVE

Transitional care is important to successful hospital discharge. Providing patients with a clear and concise summary of medication-related information can help improve outcomes, in particular, among older adults. The present study aimed to propose a framework for the development of salient medication reminders (SMR), which include drug-related risks and precautions, using the Delphi process.

DESIGN

Identification of potential SMR statements for 80% of medication types used by older adult patients discharged from geriatric medicine departments, followed by a Delphi survey and expert panel discussion.

SETTINGS

Medical and geriatric departments of public hospitals in Hong Kong.

PARTICIPANTS

A panel of 13 geriatric medical experts.

OUTCOME MEASURE

A Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree) points, scoring item relevance, importance and clarity. The minimum of 70% consensus was required for each statement to be included.

RESULTS

The expert panel achieved consensus through the Delphi process on 80 statements for 44 medication entities. Subsequently, the SMR steering group endorsed the inclusion of these statements in the SMR to be disseminated among older adults at the time of discharge from geriatric medicine departments.

CONCLUSIONS

The Delphi process contributed to the development of SMR for older adult patients discharged from public hospitals in Hong Kong. Patient experience with and staff response to the SMR were assessed at four hospitals before implementation at all public hospitals.

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.

Differences in Memory, Perceptions, and Preferences of Multimedia Consumer Medication Information: Experimental Performance and Self-Report Study

Background

Electronic health resources are becoming prevalent. However, consumer medication information (CMI) is still predominantly text based. Incorporating multimedia into CMI (eg, images, narration) may improve consumers’ memory of the information as well as their perceptions and preferences of these materials.

Objective

This study examined whether adding images and narration to CMI impacted patients’ (1) memory, (2) perceptions of comprehensibility, utility, or design quality, and (3) overall preferences.

Methods

We presented 36 participants with CMI in 3 formats: (1) text, (2) text + images, and (3) narration + images, and subsequently asked them to recall information. After seeing all 3 CMI formats, participants rated the formats in terms of comprehensibility, utility, and design quality, and ranked them from most to least favorite.

Results

Interestingly, no significant differences in memory were observed (F_2,70=0.1, P=0.901). Thus, this study did not find evidence to support multimedia or modality principles in the context of CMI. Despite the absence of effects on memory, the CMI format significantly impacted perceptions of the materials. Specifically, participants rated the text + images format highest in terms of comprehensibility (χ²₂=26.5, P<.001) and design quality (χ²₂=35.69, P<.001). Although the omnibus test suggested a difference in utility ratings as well (χ²₂=8.21, P=.016), no significant differences were found after correcting for multiple comparisons. Consistent with perception findings, the preference ranks yielded a significant difference (χ²₂=26.00, P<.001), whereby participants preferred the text + images format overall. Indeed, 75% (27/36) of participants chose the text + images format as their most favorite. Thus, although there were no objective memory differences between the formats, we observed subjective differences in comprehensibility, design quality, and overall preferences.

Conclusions

This study revealed that although multimedia did not appear to influence memory of CMI, it did impact participants’ opinions about the materials. The lack of observed differences in memory may have been due to ceiling effects, memory rather than understanding as an index of learning, the fragmented nature of the information in CMI itself, or the size or characteristics of the sample (ie, young, educated subjects with adequate health literacy skills). The differences in the subjective (ie, perceptions and preferences) and objective (ie, memory) results highlight the value of using both types of measures. Moreover, findings from this study could be used to inform future research on how CMI could be designed to better suit the preferences of consumers and potentially increase the likelihood that CMI is used. Additional research is warranted to explore whether multimedia impacts memory of CMI under different conditions (eg, older participants, subjects with lower levels of health literacy, more difficult stimuli, or extended time for decay).

Effects of Text Enhancement, Identical Prescription-Package Names, Visual Cues, and Verbal Provocation on Visual Searches of Look-Alike Drug Names: A Simulation and Eye-Tracking Study

OBJECTIVE

Simulation and eye tracking were used to examine the effects of text enhancement, identical prescription-package names, visual cues, and verbal provocation on visual searches of look-alike drug names.

BACKGROUND

Look-alike drug names can cause confusion and medication errors, which jeopardize patient safety. The effectiveness of many strategies that may prevent these problems requires evaluation.

METHOD

We conducted two experiments that were based on a four-way, repeated-measures design. The within-subject factors were text enhancement, identical prescription-package names, visual cues, and verbal provocation. In Experiment 1, 40 nurses searched for and selected a target drug from an array of drug packages on a pharmacy shelf mock-up. In Experiment 2, the eye movements of another 40 nurses were tracked while they performed a computer-based drug search task.

RESULTS

Text enhancement had no significant effect on the drug search. Nurses selected the target drugs more quickly and easily when the prescriptions and drug packages shared identical drug name formats. The use of a visual cue to direct nurses' attention facilitated their visual searches and improved their eye gaze behaviors. The nurses reported greater mental effort if they were provoked verbally during the drug search.

CONCLUSION

Efficient and practical strategies should be adopted for designs that facilitate accurate drug search. Among these strategies are using identical name appearances on drug prescriptions and packages, using a visual cue to direct nurses' attention, and avoiding rushing nurses while they are concentrating.

APPLICATION

The findings aim to inspire recommendations for work system designs that will improve the visual search of look-alike drug names.

Using pictures to convey health information: A systematic review and meta-analysis of the effects on patient and consumer health behaviors and outcomes

OBJECTIVE

Assess the effect of pictorial health information on patients' and consumers' health behaviors and outcomes, evaluate these effects in lower health literacy populations, and examine the attributes of the interventions.

METHODS

We included randomized controlled trials (RCTs) that assessed the effect of pictorial health information on patient and consumer health behaviors and outcomes. We conducted a meta-analysis of RCTs that assessed knowledge/understanding, recall, or adherence, and a subgroup analysis of those outcomes on lower health literacy populations. We narratively reviewed characteristics of pictorial health interventions that significantly improved outcomes for lower health literacy populations.

RESULTS

From 4160 records, we included 54 RCTs (42 in meta-analysis). Pictorial health information moderately improved knowledge/understanding and recall overall, but largely increased knowledge/understanding for lower health literacy populations (n = 13), all with substantial heterogeneity. Icons with few words may be most helpful in conveying health information.

CONCLUSION

Our results support including pictures in health communication to improve patient knowledge. Our results should be interpreted with caution considering the significant heterogeneity of the meta-analysis outcomes.

PRACTICE IMPLICATIONS

Future research should assess which types and characteristics of pictures that best convey health information and are most useful and the implementation and sustainability in healthcare contexts.

FDA Initiative for Drug Facts Label for Over-the-Counter Naloxone

BACKGROUND

The opioid crisis highlights the need to increase access to naloxone, possibly through regulatory approval for over-the-counter sales. To address industry-perceived barriers to such access, the Food and Drug Administration (FDA) developed a model drug facts label for such sales to assess whether consumers understood the key statements for safe and effective use.

METHODS

In this label-comprehension study, we conducted individual structured interviews with 710 adults and adolescents, including 430 adults who use opioids and their family and friends. Eight primary end points were developed to assess user comprehension of each of the key steps in the label. Each of these end points included a prespecified target threshold ranging from 80 to 90% that was evaluated through a comparison of the lower boundary of the 95% exact confidence interval.

RESULTS

The results for performance on six primary end points met or exceeded thresholds, including the steps "Check for a suspected overdose" (threshold, 85%; point estimate [PE], 95.8%; 95% confidence interval [CI], 94.0 to 97.1) and "Give the first dose" (threshold, 85%; PE, 98.2%; 95% CI, 96.9 to 99.0). The lower boundaries for four other primary end points ranged from 88.8 to 94.0%. One exception was comprehension of "Call 911 immediately," but this instruction closely approximated the target of 90% (PE, 90.3%; 95% CI, 87.9 to 92.4). Another exception was comprehension of the composite step of "Check, give, and call 911 immediately" (threshold, 85%; PE, 81.1%; 95% CI, 78.0 to 83.9).

CONCLUSIONS

Consumers met thresholds for sufficient understanding of six of eight components of the instructions in the drug facts label for naloxone use and came close on two others. Overall, the FDA found that the model label was adequate for use in the development of a naloxone product intended for over-the-counter sales.

The Canadian anaphylaxis action plan for kids: development and validation

OBJECTIVES

We designed a written Canadian Anaphylaxis Action Plan for Kids (Kids' CAP) which incorporates validated pictograms with written instructions. Using a patient-centered approach, we aimed to validate the Kids' CAP and assess its impact on anaphylaxis recognition and treatment, and to determine its' perceived usefulness.

PATIENT INVOLVEMENT

Children and their parents were involved in appraising the design and written contents of the Kids' CAP.

METHODS

The design process consisted of a development phase and clinical validation phase. First, we assessed the readability and understandability of the Kids' CAP using validated instruments. Then, patients (12-17 years of age) and parents of patients (<12 years of age) were given the Kids' CAP during the first consultation with allergy specialists or an Emergency Department visit for anaphylaxis. Subsequently, we conducted a phone interview 2-3 weeks later to assess their comprehension of anaphylaxis management. We also used the Consumer Information Rating Form to measure the participants' perception of the design quality and usefulness of the Kids' CAP.

RESULTS

Of the 230 participants enrolled, 205 (89%) completed the follow-up interview. The written contents of the Kid's CAP were modified to match grade 7 readability level. The total mean score of the Consumer Information Rating Form for comprehensibility was 23.1 (SD 2.4), and 25.1 (SD 2.3) for design quality. The mean comprehension score was 11.3 (SD 1.8) (reference range 0-12), with no significant difference between participants with and without previous experience with anaphylaxis, or high vs. low literacy level.

CONCLUSION

Engaging children and parents in the design and contents of written anaphylaxis action plan is an innovative approach to produce a useful document for the end-users.

PRACTICE IMPLICATIONS

The Kids' CAP is a valid tool that can be used in emergency departments and allergy clinics to improve patient's comprehension of anaphylaxis manifestations and treatment.

The academic-industry divide in health communication: A call for increased partnership

OBJECTIVE

Healthcare communication research, teaching, and practice is in a period of innovation and disruption from new technologies, consumerization, and emerging models of care delivery. The goal of this commentary is to discuss perceived barriers and provide baseline metrics of academic-industry partnership in health communication.

METHODS

We coded industry affiliations of authors published in Patient Education and Counseling (PEC) in 2018, and attendees and authors of accepted submissions at the 2018 International Conference on Communication in Healthcare (ICCH). We examined perceived barriers to collaboration by summarizing a roundtable discussion between industry and academic participants at the 2018 ICCH conference.

RESULTS

In 2018, less than 5% of contributions to PEC, 16 abstracts (3.1%) and only 7 attendees (1.4%) at ICCH had industry affiliations. Roundtable participants identified actual or perceived motivational differences, publication challenges, and distinct metrics/outcomes as key barriers to collaboration.

CONCLUSION

These rough estimates provide a benchmark for current industry collaboration in our professional society. We discuss potential benefits of increased partnerships, suggest approaches to reduce barriers, and highlight recent progress.

PRACTICE IMPLICATIONS

As individuals and professional organizations, we should promote ethical, multidisciplinary, and high impact research, teaching, and practice in partnership with our colleagues in industry.

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.

Systematic Development of Materials for Inviting Low Health-Literate Individuals to Participate in Preconception Counseling

In this study we aimed to systematically analyze problems in the recruitment of women with low health literacy for preconception counseling and to adapt and evaluate written invitations for this group. In a problem analysis (stage 1) we used structured interviews (n = 72) to assess comprehension of the initial invitations, perception of perinatal risks, attitude and intention to participate in preconception counseling. These outcomes were used to adapt the invitation. The adapted flyer was pretested in interviews (n = 16) (stage 2) and evaluated in structured interviews among a new group of women (n = 67) (stage 3). Differences between women in stages 1 and 3 regarding comprehension, risk perception, attitude and intention to participate in counseling were analyzed by linear regression analysis and chi-square tests. Women in stage 3 (who read the adapted flyer) had a more positive attitude towards participation in preconception counselling and a better understanding of how to apply for a consultation than women in stage 1 (who read the initial invitations). No differences were found in intention to participate in preconception counseling and risk perception. Systematic adaptation of written invitations can improve the recruitment of low health-literate women for preconception counselling. Further research should gain insight into additional strategies to reach and inform this group.

Attitudes towards deprescribing and the influence of health literacy among older Australians

Aim

This study aimed to explore attitudes, beliefs and experiences regarding polypharmacy and discontinuing medications, or deprescribing, among community living older adults aged ≥65 years, using ≥5 medications. It also aimed to investigate if health literacy capabilities influenced attitudes and beliefs towards deprescribing.

Background

Polypharmacy use is common among Australian older adults. However, little is known about their attitudes towards polypharmacy use or towards stopping medications. Previous studies indicate that health literacy levels tend to be lower in older adults, resulting in poor knowledge about medications.

Methods

A self-administered survey was conducted using two previously validated tools; the Patients’ Attitude Towards Deprescribing (PATD) tool to measure attitudes towards polypharmacy use and deprescribing and the All Aspects of Health Literacy Scale (AAHLS) to measure functional, communicative and critical health literacy. Descriptive statistical analysis was conducted.

Findings

The 137 responses showed that 80% thought all their medications were necessary and were comfortable with the number taken. Wanting to reduce the number of medications taken was associated with concerns about the amount taken (P<0.001), experiencing side effects (P<0.001), or believing that one or more medications were no longer needed (P<0.000). Those who were using ten or more medications were more likely to want to reduce the number taken (P=0.019). Most (88%) respondents would be willing to stop medication/s in the context of receiving this advice from their doctor. Willingness to consider stopping correlated with higher scores on the critical health literacy subscale (P<0.021) and overall AAHLS score (P<0.009). Those with higher scores on the overall AAHLS measure were more likely to report that they understood why their medications were prescribed (P<0.000) and were more likely to participate in decision-making (P=0.027). Opportunities to proactively consider deprescribing may be missed, as one third of the respondents could not recall a recent review of their medications.

Investigating the efficacy of an interactive warning for use in labeling strategies used by us pharmacies

Background

United States pharmacies repackage medications into multi-dose vials, enabling customized dosing for prescription drugs. Investment in infrastructure has made this the predominant approach to packaging for US prescriptions. Although recent changes to labeling now discourage the use of auxiliary labels (small stickers highlighting information germane to the safe and effective use), they are still allowed by USP<17>, provided their use comes from an evidence-based perspective.

Objectives

Evaluate how 'interactive,' placements of auxiliary labels (placement requiring physical manipulation of the warning to accomplish a task (e.g. opening)) garner attention as compared to those placed vertically or horizontally.

Methods

Ninety-six participants were eye tracked while opening three prescription vials (each with an auxiliary warning label with a different placement: vertical, horizontal and interactive). Recall and recognition were tested subsequently. Linear mixed models were used to analyze the continuous variables while the binary response variables were analyzed using generalized linear mixed models. The effect of auxiliary labels was fitted as a fixed effect and the subject-to-subject variation was considered as a random effect in the model. Participants' age, health literacy and sex were added to the models if their effect was statistically significant at alpha=0.05.

Results

The placement of the warnings significantly impacted the time spent viewing the information they contained at alpha=0.05; people spent significantly longer on interactive placements (0.96; SD 0.13 seconds) than either, horizontal placements (0.27; SD 0.037 seconds) or those placed vertically (0.18 seconds; SD 0.035). Participants were equally as likely to see information presented in an interactive placement (90%; SD 3.8) or horizontal placement (78%; SD 05.5) but less likely to view warnings placed vertically (60%; SD 6.9). Free recall responses also supported the use of interactive placement (62%; SD 6.8 recall) as compared to horizontal placements which were 29%; SD 3.0 and 20%; SD 6.0 for vertical placements.

Conclusions

Data provides evidence which suggests that interactive and horizontal placements out-perform auxiliary labels placed vertically on prescription vials with regard to garnering patient attention.
