Reducing avoidable medication-related harm: What will it take?

Effect of pharmaceutical pictograms on the textual comprehension of Prescription Medication Leaflets: A randomized controlled trial

INTRODUCTION

Clear patient instructions are essential in pharmaceutical care. However, literature reveals a consistent gap between the readability of medication messages and population skills. This study aimed to assess the comprehension of information in three Prescription Medication Leaflets, with and without supplementary US Pharmacopeia (USP) pictograms, among Spanish adolescents completing secondary education.

METHODS

We conducted a multicenter randomized controlled trial. From March to June 2022, 590 students were randomly assigned to read Prescription Medication Leaflets for ibuprofen, amoxicillin/clavulanic acid, and omeprazole, with or without USP pictograms. Comprehension was evaluated via questionnaire, alongside the European Health Literacy Survey short form, and sociodemographic data were collected. Mann-Whitney U and chi-square tests were used for analysis.

RESULTS

Participant comprehension was significantly below the European standard, which requires at least 80 % readability for Prescription Medication Leaflets, even with pictograms. Pictograms, however, significantly enhanced comprehension across all medication package inserts (p < 0.001 for all comparisons), especially among students with higher health literacy. High health literacy was a statistically significant factor in comprehension only within the experimental group (p = 0.005; p = 0.039; p = 0.004).

CONCLUSION

The discouraging results highlight the imperative for innovation in medication labeling design, employing patient-centered approaches. USP pictograms have been shown to significantly enhance the reading comprehension of medication package inserts among the Spanish population.

Alignment of Patient Information Leaflets with the Health Literacy Skills of Future End-Users: Are We on the Same Page?

Effective health communication will not be possible if the messages directed to patients do not adapt to their health literacy skills. In this sense, if the Patient Information Leaflets (PILs) are not understood properly, they will not fulfill their purpose. Secondary education aims to develop students' fundamental skills, including reading comprehension, which should align with future patients. This study assesses reading comprehension of commonly used PILs among secondary education students. An observational cross-sectional study involved 590 Spanish secondary school students from March to June 2022. They read 3 original PILs and completed a questionnaire about medication use information. The European health literacy survey questionnaire (short version) and sociodemographic data were collected. The average correct answer rate was only 51%, with just 14.58% understanding when to take ibuprofen, results that fell significantly below the minimum 80% threshold required by the European Union. Age, gender, and cultural background didn't significantly impact comprehension. In conclusion, health literacy skills acquired in secondary education are insufficient for understanding current PILs. Educational reform is necessary to improve students' ability to comprehend medication instructions and enhance PILs for effective communication. At the same time, our work highlights that current PILs need to be redesigned to reduce the cognitive burden imposed on patients.

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

BACKGROUND

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

OBJECTIVES

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Association of burnout with depression in pharmacists: A network analysis

Background

Burnout and depression have overlapping symptoms, but the extent of overlap remains unclear, and the complex relationship between burnout and depression in pharmacists is rarely explored.

Methods

We investigated burnout and depression in 1,322 frontline pharmacists, and explored the complex relationship between burnout and depression in those pharmacists using network analysis.

Results

Network analysis showed that there were 5 communities. A partial overlap was found between burnout and depressive symptoms in pharmacists. The nodes MBI-6 (I have become more callous toward work since I took this job), D18 (My life is meaningless), and D10 (I get tired for no reason) had the highest expected influence value. D1 (I feel down-hearted and blue) and D14 (I have no hope for the future) were bridge symptoms connected with emotional exhaustion and reduced professional efficacy, respectively.

Conclusion

A partial overlap exists between burnout and depressive symptoms in pharmacists, mainly in the connection between the emotional exhaustion and reduced professional efficacy and the depressive symptoms. Potential core targets identified in this study may inform future prevention and intervention.
