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.

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.

Pharmaceutical pictograms: User-centred redesign, selection and validation

Objective

In an earlier study, several tested International Pharmaceutical Federation (FIP) pictograms did not achieve validity among older adults in Singapore. In this study, for 27 unvalidated FIP pictograms, we (1) developed variants of each pictogram, (2) elicited the most-preferred variant, and (3) assessed the validity of the most-preferred variant among older Singaporeans.

Methods

In phase 1, up to three variants of the 27 pictograms were developed, based on older adults' feedback from a previous study. In phase 2, the most-preferred variant of 26 pictograms, which had two or three variants, was selected by 100 older participants. In phase 3, the 27 most-preferred variants (including the pictogram with only one variant) were assessed for validity - transparency and translucency - among 278 older participants (10 pictograms per participant). To evaluate transparency, participants were first asked: "If you see this picture on a medicine label, what do you think it means?" for each assigned pictogram. If they responded, they were asked, "How do you know?", and if not, they were told, "Tell me everything you see in this picture". Then, participants were shown their assigned pictograms again, one by one, and the pictogram's intended meaning was revealed to evaluate translucency. Pictograms were classified as valid (≥66% participants interpreted its intended meaning correctly [transparency criterion] and ≥85% participants rated its representativeness as ≥ 5 [translucency criterion]), partially valid (only transparency criterion fulfilled) or not valid.

Results

In phase 1, 77 variants of the 27 pictograms were developed. In phase 2, a majority of the most-preferred variants were selected by >50% participants. In phase 3, 10 (37.0%) of the 27 pictograms tested were considered valid, and five (18.5%) were partially valid. A higher proportion of pictograms portraying dose and route of administration and precautions were valid or partially valid, versus those depicting indications or side effects.

Conclusion

Contextual redesigning and selection of pharmaceutical pictograms, which initially failed to achieve validity in a population, contributed to their validation.

Innovation

The redesigned validated pictograms from this study can be incorporated into relevant patient information materials in clinical practice.

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.

Public sentiments and the influence of information-seeking preferences on knowledge, attitudes, death conversation, and receptiveness toward palliative care: results from a nationwide survey in Singapore

Background

Low awareness about palliative care among the global public and healthcare communities has been frequently cited as a persistent barrier to palliative care acceptance. Given that knowledge shapes attitudes and encourages receptiveness, it is critical to examine factors that influence the motivation to increase knowledge. Health information-seeking from individuals and media has been identified as a key factor, as the process of accessing and interpreting information to enhance knowledge has been shown to positively impact health behaviours.

Objective

Our study aimed to uncover public sentiments toward palliative care in Singapore. A conceptual framework was additionally developed to investigate the relationship between information-seeking preferences and knowledge, attitudes, receptiveness of palliative care, and comfort in death discussion.

Design and Methods

A nationwide survey was conducted in Singapore with 1226 respondents aged 21 years and above. The data were analysed through a series of hierarchical multiple regression to examine the hypothesised role of information-seeking sources as predictors.

Results

Our findings revealed that 53% of our participants were aware of palliative care and about 48% were receptive to receiving the care for themselves. It further showed that while information-seeking from individuals and media increases knowledge, attitudes and receptiveness to palliative care, the comfort level in death conversations was found to be positively associated only with individuals, especially healthcare professionals.

Conclusion

Our findings highlight the need for public health authorities to recognize people's deep-seated beliefs and superstitions surrounding the concept of mortality. As Asians view death as a taboo topic that is to be avoided at all costs, it is necessary to adopt multipronged communication programs to address those fears. It is only when the larger communicative environment is driven by the media to encourage public discourse, and concurrently supported by timely interventions to trigger crucial conversations on end-of-life issues between individuals, their loved ones, and the healthcare team, can we advance awareness and benefits of palliative care among the public in Singapore.

Culturally and linguistically diverse patients' perspectives and experiences on medicines management in Australia: a systematic review

BACKGROUND

Within the quality use of medicines (QUM)-which entails timely access to, and the rational use of, medicines-medicine safety is a global health priority. In multicultural countries, such as Australia, national medicines policies are focused on achieving QUM, although this is more challenging among their Culturally and Linguistically Diverse (CALD) patients (i.e., those from ethnic minority groups).

AIM

This review aimed to identify and explore the specific challenges to achieving QUM, as experienced by CALD patients living in Australia.

METHOD

A systematic literature search was conducted using Web of Science, Scopus, Academic search complete, CINHAL, PubMed and Medline. Qualitative studies describing any aspects of QUM among CALD patients in Australia were included.

RESULTS

Major challenges in facilitating QUM among CALD patients in Australia were identified, particularly in relation to the following medicines management pathway steps: difficulties around participation in treatment decision-making alongside deficiencies in information provision about medicines. Furthermore, medication non-adherence was commonly observed and reported. When mapped against the bio-psycho-socio-systems model, the main contributors to the medicine management challenges identified related to "social" and "system" factors, reflecting the current health-system's lack of capacity and resourcing to respond to patients' low health literacy levels, communication and language barriers, and cultural and religious perceptions about medicines.

CONCLUSION

QUM challenges were different among different ethnic groups. This review suggests a need to engage with CALD patients in co-designing culturally appropriate resources and/or interventions to enable the health-system to address the identified barriers to QUM.

Factors influencing medication adherence in multi-ethnic Asian patients with chronic diseases in Singapore: A qualitative study

Background: Poor medication adherence can lead to adverse health outcomes and increased healthcare costs. Although reasons for medication adherence have been widely studied, less is explored about factors affecting medication adherence for patients in non-Western healthcare setting and from Asian cultures. This study aimed to explore cultural perspectives on factors influencing medication adherence among patients with chronic diseases in a multi-ethnic Asian healthcare setting.

Methods: We conducted a qualitative study involving in-depth interviews with patients with chronic conditions purposively recruited from a community hospital in Singapore until data saturation was achieved. A total of 25 patients participated in this study. Interviews were transcribed and thematically analyzed. Themes were subsequently mapped into the World Health Organization (WHO) Framework of Medication Adherence.

Results: Participants commonly perceived that sides effects (therapy-related dimension), poor understanding of medication (patient-related dimension), limited knowledge of condition (patient-related dimension), forgetfulness (patient-related dimension) and language issues within a multi-ethnic healthcare context (healthcare team and system-related dimension) as the main factors contributing to medication adherence. Importantly, medication adherence was influenced by cultural beliefs such as the notion of modern medicines as harms and fatalistic orientations towards escalation of doses and polypharmacy (patient-related dimension). Participants made various suggestions to foster adherence, including improved patient-physician communication, enhanced care coordination across providers, use of language familiar to patients, patient education and empowerment on the benefits of medication and medication adjustment.

Conclusion: A wide range of factors influenced medication adherence, with therapy- and patient-related dimensions more pronounced compared to other dimensions. Findings demonstrated the importance of cultural beliefs that may influence medication adherence. Future efforts to improve medication adherence should consider a person-centered approach to foster more positive health expectations and self-efficacy on medication adherence, supplemented with routine reviews, development of pictograms and cultural competence training for healthcare professionals.

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.

Prevalence and correlates of use of digital technology for managing hypertension among older adults

Hypertension is prevalent among older adults (60 years and above), but control of blood pressure (BP) remains suboptimal. While there is increasing interest in using digital technology for managing hypertension, information about the extent and potential correlates of such use among older adults remains scant. We assessed the prevalence and correlates of the use of digital technology for managing hypertension among older adults with hypertension. We also investigated if the use of digital technology was associated with BP or hypertension control. The use of digital technology (internet or digital apps) for information about or managing BP or hypertension was assessed among 1729 older adults diagnosed with hypertension participating in a national survey in Singapore. Regression analysis was used to assess the correlates (based on the Unified Theory of Use and Acceptance of Technology), and whether such use was associated with hypertension control or BP values. Digital technology for managing hypertension was used by 7.1% of older adults with hypertension. Those of higher age and with limitations in one or more activities or instrumental activities of daily living were less likely, while those with secondary education and above, and with stronger social network were more likely to use digital technology. There was no association between the use of digital technology and hypertension control. While users of digital technology had lower systolic (by 2.1 mmHg, adjusted p value = 0.12) and diastolic (by 1.6 mmHg, adjusted p value = 0.13) BP than non-users, the differences were not statistically significant. Given its low prevalence, there is potential for increased use of digital technology for managing hypertension among older adults with hypertension in Singapore. Initiatives to increase digital health use should target specific older adult subgroups.

Improving safety in the operating room: Medication icon labels increase visibility and discrimination

Misreading labels, syringes, and ampoules is reported to make up a 54.4% of medication administration errors. The addition of icons to medication labels in an operating room setting could add additional visual cues to the label, allowing for improved discrimination, visibility, and easily processed information that might reduce medication administration errors. A multi-disciplinary team proposed a method of enhancing visual cues and visibility of medication labels applied to vasoactive medication infusions by adding icons to the labels. Participants were 1.12 times more likely to correctly identify medications from farther away (p < 0.001, AOR = 1.12, 95% CI: 1.02, 1.22) with icons. When icons were present, participants were 2.16 times more likely to be more confident in their identifications (p < 0.001, AOR = 2.16, 95%CI: 1.80, 2.57). Carefully designed icons may offer an additional method for identifying medications, and thus reducing medication administration errors.

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.

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.

Telemedicine use in orthopaedics: Experience during the COVID-19 pandemic

INTRODUCTION

With a recent resurgence of the 2019 coronavirus disease (COVID-19) cases globally, an increasing number of healthcare systems are adopting telemedicine as an alternative method of healthcare delivery in a bid to decrease disease transmission. Continued care of orthopaedic patients in the outpatient setting during the coronavirus disease of 2019 era can prove challenging without a systematic workflow, adequate logistics, and careful patient selection for teleconsultation. The aim of this paper is to describe our single-centre experience with the application of telemedicine in our orthopaedic practice, and its effectiveness in maintaining outpatient follow-up of orthopaedic patients.

METHODOLOGY

We describe our centre's telemedicine model of care for orthopaedic patients on the outpatient follow-up - which includes workforce assembly, population health and target patients, logistics and communications, and overall workflow - with roles and responsibilities of involved people portrayed in detail.

RESULTS

Feedback from both patients and orthopaedic surgeons reflected high satisfaction rates with care provided, noting minimal communication and clinical barriers compared to face-to-face consultations. Whilst not without limitations, our protocol allowed for rapid adoption of telemedicine in line with a national-wide initiative to digitize healthcare.

DISCUSSION

The implementation of teleconsultation services at our orthopaedic centre has provided an effective method of healthcare delivery while enforcing social distancing measures - which proves vital in combating the spread of COVID-19 and ushering in a new normal.

Blood pressure and adiposity in midlife Singaporean women

Hypertension is a major risk factor for cardiac events and stroke. Visceral adipose tissue (VAT) is known to increase the risk of incident hypertension in adults. Although adiposity has been linked to markers of inflammation, few studies have examined these markers as potential mediators of the association between visceral adiposity and elevated blood pressure. We evaluated sociodemographic, reproductive, and lifestyle risk factors for elevated blood pressure among midlife Singaporean women. A total of 1189 women, with a mean age of 56.3 ± 6.2 years, from the Integrated Women's Health Program (IWHP) at National University Hospital, Singapore were studied. Hypothesized risk factors and levels of inflammatory markers were examined in relation to systolic blood pressure (SBP) and diastolic blood pressure (DBP) using multivariable linear regression models. Prehypertension (SBP 120-139 mmHg and/or DBP 80-89 mmHg) and hypertension (SBP ≥140 mmHg and/or DBP ≥90 mmHg) were observed in 518 (43.6%) and 313 (26.3%) women, respectively. Compared to women in the lowest tertiles, women in the middle and upper tertiles of VAT had 7.1 (95% CI, 4.4, 9.8) mmHg and 10.2 (95% CI, 6.7, 13.7) mmHg higher adjusted SBP, respectively. Nulliparous older women with a lower education level and those with no or mild hot flashes also had a significantly higher adjusted SBP. No significant independent risk factors were observed for DBP. Adjustments for IL-6, TNF-α, and hs-CRP did not attenuate the association between VAT and SBP. In summary, we found an independent positive association between VAT and SBP. Elevated levels of inflammatory markers did not mediate the increase in SBP in women with high VAT.

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.

Mediators of the association of limited English health literacy with medication non-adherence among Singaporean elderly

Background:

In Singapore, English is predominantly used on prescription medication labels (PMLs). However, many older Singaporeans cannot read English, and among those who read English, their English health literacy (EHL) proficiency varies. It is thus pertinent to examine the link between EHL and medication use outcomes in this population. The present research aims to address this question.

Methods:

Data from a national survey, on 1167 home-dwelling elderly on ⩾1 prescribed medication was analysed. The validated Health Literacy Test for Singapore was used to determine EHL. Medication non-adherence was self-reported. Path analysis examined the association between limited EHL and medication non-adherence and tested possible mediators.

Results:

Limited EHL was associated with medication non-adherence (total effect=0.35; p-value: 0.032), and ‘uncertainty in taking medications correctly due to difficulty in understanding written information on PMLs’ was a significant mediator (indirect effect=0.23, 95% confidence interval (0.12–0.39)).

Conclusions:

Elderly people with limited EHL were significantly more likely than those with adequate EHL to report that they were uncertain about taking medications correctly because they had difficulty understanding the information on PMLs and this misunderstanding contributed to medication non-adherence. Interventions focused on incorporating bilingual text and/or pictograms on PMLs may reduce uncertainty in taking medication correctly and improve medication adherence among the elderly.

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.

Literature Review: Strategies for Addressing Language Barriers During Humanitarian Relief Operations

Humanitarian relief operations (HUMRO) represent a nexus between military diplomacy and global health engagement, and may play an increasing role in military operations in the near future. Language barriers between providers and the individuals being assisted are a significant constraint on HUMRO. A literature review was conducted to identify recommendations to address patient-provider language discordance in the international HUMRO context. This was supplemented by a North Atlantic Treaty Organization and US Department of Defense doctrinal review to identify existing best practices for addressing language barriers. Four general themes were identified: (1) print-based aids, (2) information technology, (3) bilingual responders, and (4) the effective use of medical interpreters in the HUMRO setting. Each strategy is reviewed. Informed by expert opinion, we provide concrete leadership and training recommendations for how HUMRO providers might more effectively communicate with patients in a deployed language-discordant context.

Polypharmacy among community-dwelling elderly in Singapore: Prevalence, risk factors and association with medication non-adherence

Background:

Polypharmacy, given its link with drug interactions, potentially inappropriate medications and medication non-adherence, may pose a significant health risk, especially among the elderly. A comprehensive understanding of the epidemiology of polypharmacy is essential for countries facing population ageing and growing chronic disease burden, like Singapore.

Objectives:

We assessed the prevalence and risk factors of polypharmacy (⩾5 prescription medications) among community-dwelling elderly in Singapore and established the association of polypharmacy with medication non-adherence.

Methods:

We used data from a national sample of 1499 community-dwelling elderly aged ⩾66 years. Using logistic regression, we assessed the association of socio-demographic, health and healthcare use variables with polypharmacy, and polypharmacy with medication non-adherence.

Results:

The weighted prevalence of polypharmacy was 14.5%. In multivariable analysis, elderly who were men (versus women), with ⩾2 (versus 0–1) chronic diseases, aged ⩾85 (versus 66–69) years, and of Malay and Indian (versus Chinese) ethnicity were significantly more likely to have polypharmacy; healthcare use variables were not associated. Polypharmacy was significantly correlated with medication non-adherence.

Conclusions:

The prevalence of polypharmacy among community-dwelling elderly in Singapore is lower than that reported in other countries; however, polypharmacy is associated with medication non-adherence. Elderly subgroups, defined by gender, health status, age and ethnicity, who are at a higher risk of polypharmacy will benefit from medication review and de-prescribing services.

Provision of Bilingual Dispensing Labels to Non-Native English Speakers: An Exploratory Study

Patients with limited English proficiency living in the U.K. receive prescribed medication labels in English. These patients are at risk of worse health outcomes compared with the general population. This article describes a service evaluation of the use of bilingual dispensing labels to facilitate patient understanding of medicine administration instructions. Recruited patients answered two questionnaires to assess engagement with and understanding of their medicine labels. The first was completed at the point of dispensing, and the second within six weeks. Questionnaires were either self-completed or via facilitation over the telephone. A total of 151 participants completed the first questionnaire, and 130 completed the follow-up. Key findings highlighted the lack of engagement by participants with English-language labels and their reliance on asking for help from pharmacy staff, friends, or family to understand the information. However, when provided with information in their preferred language, they reported high levels of understanding and sought help less frequently from a third party. This study has shown that this service has improved understanding of labelling information in this target group.

How Social Participation Benefits the Chronically Ill: Self-Management as a Mediating Pathway

Objective: Few studies have tested the purported causal mechanisms between social participation and health, especially among those in poor health. This study aimed to determine whether self-management of chronic disease operates as a pathway through which social participation affects health-related quality of life. Method: I utilized causal mediation analysis among 600 low-income older Singaporeans living with chronic conditions, to test whether self-management mediates the association between social participation and health-related quality of life. Results: Results show that self-management fully mediated the positive effect of informal social participation on health-related quality of life. Formal social participation was found to have a negative direct effect on health-related quality of life. Discussion: These findings reiterate the primacy of family and friends for older adults, but highlight that a better understanding of formal engagement with the low-income population is still needed.
