User testing to examine patient understanding of pharmacy generated medication labels

Sleep medicines are often prescribed for older adults (≥75 years) without appropriate dosing instructions: A nationwide retrospective register study in Finland

BACKGROUND

Sleep medicines should be prescribed cautiously, accompanied by instructions that ensure appropriate use and reduce risks. This is especially important for older adults, for whom many of these medicines are classified as potentially inappropriate medicines.

METHODS

We investigated the use and appropriateness of dosing instructions for sleep medicines (described in the Finnish National Current Care Guideline for Insomnia) prescribed for older adults (≥75 years) and dispensed with instruction label in pharmacies. The retrospective reimbursement register data for year 2020 by the Social Insurance Institution of Finland was used as the data source (1,080,843 purchases by 143,886 individuals of which 565,228 purchases were pharmacy dispenses). The appropriateness of the pharmacy dosing instructions containing keyword(s) referring to insomnia treatment was examined according to the prescribed dose, time of intake, frequency of use, and warnings/remarks. A random sample of 1000 instructions was used to manually analyze the phrasing and appropriateness.

OUTCOMES

We focused our analysis on 58.1% (328,285 purchases by 87,396 individuals) of the pharmacy dispenses, which contained dosing instructions referring insomnia treatment. Of these, zopiclone and mirtazapine were the most prescribed drugs (134,631 and 112,463 purchases, respectively). Dose and time of intake were specified in most of the instructions (98.4% and 83.4%, respectively), whereas frequency of use was specified in 57.3%. A small percentage of the instructions included warnings/remarks (2.8%). Overall, only 2.1% of the instructions contained information about a single dose, time of intake, temporary use, and warnings/remarks and were thus defined as sufficient. Notably, 47.7% (n = 515,615) of all the purchases in our dataset were dispensed via automated multi-dose dispensing systems, which is aimed for long-term treatment.

INTERPRETATION

It is common to prescribe sleep medicines for older adults without appropriate dosing instructions, particularly excluding warnings against long-term, regular use. Actions to change the current prescribing practices are warranted.

Do pediatric oral suspension acetaminophen and ibuprofen product labeling and online resources facilitate intended use?

Background

Caregivers often have difficulty administering pediatric medications which frequently results in increased dosing error risk.

Objective

We examined health literacy characteristics of pediatric over-the-counter (OTC) oral suspension acetaminophen and ibuprofen instructional materials and dosing instruments.

Methods

We conducted a descriptive analysis of dosing instructions, measuring syringe characteristics, and internet-based resources among a sample of OTC pediatric oral suspension acetaminophen and ibuprofen products (n = 14).

Results

All products included Drug Facts Panels, employed consistent abbreviation use, and stated measuring dosage with syringe provided. However, oral syringe dosing increment markings did not match box or bottle dosing charts. Most products had supplemental English-language internet-based content resources available.

Conclusions

While OTC pediatric oral suspension acetaminophen and ibuprofen products labeling included key drug fact elements, there were inconsistencies between medication dosing chart labeling guidelines and oral syringe dosing increments/markings. It is vital that oral dosing syringes are clearly marked to match product dosing chart labeling s as a means of potentially reducing caregiver dosing errors.

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.

Investigating the impact of patient-centred labels on comprehension of medication dosing: a randomised controlled trial

OBJECTIVE

This study aims to implement a version of patient-centred labels (PCL) consistent with current labelling practice in Australia; assess the effectiveness of PCL in relation to the proportion of participants that correctly comprehend dosing instructions, and explore the proportion of correct comprehension of PCL in participants with both low and high health literacy.

DESIGN

Randomised controlled trial.

SETTING

A large tertiary care hospital in Brisbane, Queensland, Australia.

PARTICIPANTS

121 participants with a majority born in Australia (65.3%), New Zealand (14.0%), the UK (6.6%) and Ireland (2.5%).

INTERVENTION

Participants were randomly assigned to either a panel of three PCL (n=61) or three standard labels (n=60) and asked to comprehend their assigned panel of labels.

OUTCOME MEASURES

Difference in the proportion of participants that correctly comprehend dosing instructions provided on PCL compared with standard labels. The two-proportion test was used to measure the impact of PCL on the proportion of participants correctly comprehending dosing instructions.

RESULTS

A greater proportion of participants were able to accurately comprehend PCL compared with standard labels. The proportion of participants who were able to correctly comprehend dose instructions provided on all three labels was significantly higher in the group that received PCL; 23.3% standard vs 83.6% PCL, p<0.001. The effect was observed in both low and high health literacy participants. The proportion of participants with accurate label comprehension was higher in participants with low Newest Vital Signs scores (8.3% standard vs 85.7% PCL, p<0.001) and low Rapid Estimate of Adult Literacy in Medicine scores (10.5% standard vs 96.0% PCL, p<0.001) who received PCL.

CONCLUSION

This study supports the use of PCL in Australian pharmacy practice. PCL provide simple, clear and explicit dosing instructions to patients. Implementing PCL may reduce the risk of misinterpreting dosing instructions by patients and improve quality use of medicines.

Vulnerability of poorly literate adult consumers regarding over-the-counter drugs

Purpose

This study aims at verifying the impact of literacy on over-the-counter (OTC) drug consumer vulnerability as evaluated by health literacy and label comprehension.

Design/methodology/approach

The item response theory (IRT) was used to estimate the health literacy of two groups and the two-way analysis of variance tests was used to test the hypotheses for the existence of mean differences between the two populations. The convenience sample involved 188 OTC consumers: 94 (50%) poorly literate and 94 (50%) university students/graduates.

Findings

University consumers/graduates have a level of health literacy and label comprehension that is superior to those presented by poor literate consumers. Also, age does not influence the level of health literacy by OTC drug users but has a significant impact on the understanding of OTC drug labels. Finally, the level of schooling and the “age group,” simultaneously, does not impact the understanding of OTC drug labels or health literacy.

Research limitations/implications

This study has added in the field of knowledge by investigating the behavior of poor literate consumers in Brazil, a developing country. The results may be relevant to Marketing professionals, especially those in the pharmaceutical industry, and to police makers, as they help identify the main problems faced by poorly literate consumers.

Practical implications

It is necessary to raise awareness of the dangers of self-medication and wrong use of medications, mainly focused on people with low literacy. As a suggestion, a simple glossary presented along with the label could provide explanations of scientific terms, thus increasing health literacy and reducing the vulnerability of the consumers.

Social implications

This study showed that when using common words such as gastritis to define a health problem, there is a higher degree of correctness. These results suggest the adoption of a more straightforward language and more precise explanations. By doing that, the pharmaceutical industry and policymakers will improve their social impact by increasing consumer power and taking care of the health of the most vulnerable population: the illiterate people.

Originality/value

This study contributes to the international literature, as it enhances and clarifies the knowledge about the customers’ power and vulnerability in developing countries. It fills a gap by evaluating label comprehension and heath literacy at the same time, giving an academic contribution for pharmaceutical consumers’ studies.
