Patients' Experiences and Preferences for Medicine Information: An International Comparison Between Malaysia, Thailand, Uganda, and England

Background

Verbal and written medicine information are available to the public but the quality, ease of access, ease of understanding and use of these resources varies greatly between countries. Timely access to quality medicine information is essential to support patient safety.

Objective

This international cross-sectional survey, conducted in low-to high-income countries, aimed to compare experiences of and preferences for medicine information sources among respondents with recent medicine use.

Methods

The survey was originally developed in England (Kent), then adapted and translated for use in southern Thailand (Songkhla), Malaysia (Klang Valley), and central Uganda (Kampala). Data were analysed using simple descriptive statistics and Chi-squared tests.

Results

A total 1588 respondents were involved in the study. Community pharmacies were the primary source of medicines in all four countries (40.7 to 65.3%). Most respondents (1460; 92%) had received at least one form of information with their medicine, but provision of written medicine information (WMI) varied between countries. A manufacturer's leaflet was the most frequent information source for patients in England, while verbal information was common in Thailand, Malaysia and Uganda. There was commonality across countries in the desire for verbal information with or without WMI (1330; 84.8%); aspects of medicine information wanted most frequently were instructions on medicine use (98.3%), indication (98.2%), name (94.4%) and possible side effects (94.3%); and the importance of providing leaflets with all medicines (87.5%). Fewer than 10% in Uganda would use internet based WMI, compared to between 20% and 55% elsewhere.

Conclusion

Preferences for medicine information are similar across countries: verbal information is seen as most desirable, and the most wanted aspects of information are common internationally. Accessibility and understandability are key influences on preferred information sources. In-country regulations and practices should ensure that all medicine users can access the information necessary to maximise safe medicine use.

A Comparative Evaluation of Drug Information Leaflets of Over-the-Counter Medicines in Palestine

Our study aims to conduct an evaluation and comparison between the leaflets of local and imported oral solid over-the-counter medications (OTC) found in the Palestinian markets. Forty-nine leaflets were evaluated using a scoring method and depending on the appearance of 31 headings, along with the use of manual word counting to assess the amount of information within 23 topics of all 31. None of the evaluated PIs, local or imported, completed all 31 criteria. Remarkably, the imported product leaflets achieved higher scores than their local leaflets in 19 out of 31 topics, whereas the local products achieved better scores than the imported agents in only 2 items, and 10 criteria were equally scored between them. None of the PIs mentioned pharmacokinetic information, instructions for converting tablets or capsules into liquid forms, or shelf life. In general, imported leaflets give more detailed information than their local counterparts. The lowest value of the fold difference in mean rank was 0.85 times for the direction of use, and the highest value was 2.43-fold for adverse drug reactions. The results showed a deficiency in the information provided in the local package inserts compared to the imported versions of oral solid OTC medications available in Palestine. These findings encourage the Palestinian Ministry of Health to provide full criteria for pharmaceutical companies to ensure that the leaflets contain sufficient and updated information and ensure that the patients use their drugs safely and effectively.

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.
