Development and evaluation of user-tested Thai patient information leaflets for non-steroidal anti-inflammatory drugs: Effect on patients' knowledge

Evaluation of Medicine Information Leaflets for Omeprazole, Safety Knowledge, and Perceptions of Taking the Medication in Thailand

PURPOSE

This study aimed to compare package inserts and patient information leaflets for omeprazole in terms of the quality of and satisfaction with the written medicine information, medication safety knowledge, and perceived benefits and risks.

PATIENTS AND METHODS

A cross-sectional, comparative study was conducted at a university hospital in Thailand. Outpatients visiting the pharmacy departments prescribed omeprazole were randomly selected to receive either a package insert or a patient information leaflet. Medication safety knowledge was measured using a set of eight questions. The quality of the written medicine information was measured by the Consumer Information Rating Form. Perceived benefits and risks of the medication were rated using a visual analog scale. Linear regression was used to determine factors associated with perceived benefits and risks.

RESULTS

Of the 645 patients, 293 agreed to answer the questionnaire. 157 and 136 patients were given patient information leaflets and package inserts, respectively. Most respondents were female (65.6%), over half had a degree (56.2%). Patients reading the patient information leaflets had slightly higher overall safety knowledge scores than those reading the package inserts (5.88 ± 2.25 vs 5.25 ± 1.84, p=0.01). Using the Consumer Information Rating Form, the patient information leaflets were given significantly higher scores compared to the package inserts for comprehensibility (19.34±3.92 vs 17.32±3.52, p<0.001) and design quality (29.25 ± 5.00 vs 23.81 ± 5.16, p<0.001). After reading the leaflets, patients receiving the patient information leaflets had significantly higher satisfaction with the information provided (p=0.003). In contrast, those receiving the package inserts rated the risks of omeprazole higher (p=0.007).

CONCLUSION

Demonstrable differences were found from the patient perspective between a package insert and a patient information leaflet for the same medicine, mostly in favour of patient information leaflets. Medicine safety knowledge after reading PI and PIL was similar. However, receiving package inserts provided higher perceived risks from taking the medicine.

Co-design to increase implementation of insomnia guidelines in primary care

BACKGROUND

Sleep disorders, including insomnia, are widespread problems, which have increased during the COVID-19 pandemic. Guidelines for the treatment of insomnia prioritize non-pharmacological interventions. Nevertheless, primary care professionals lack well-developed material for patient education, that could help implement the treatment guidelines in Flanders, Belgium.

OBJECTIVE

This project's purpose is to develop complementary, written educational material, grounded in the principles of evidence-based practice, for primary care.

PATIENT INVOLVEMENT

This co-design project involved patients and health professionals. Special attention was given to including patients with low health literacy, and empowering patients when designing in mixed groups.

METHODS

Based on the framework of Sanders and Stappers (2014), data were collected and analyzed in four phases. Pre-design, needs were explored using think-aloud studies and focus groups. Next, for generative purposes, the design studio method was used. Then, evaluation of the prototype happened with another series of think-aloud studies. Finally, post-design, implementation of the product was evaluated with a short survey.

RESULTS

Twenty-five participants (10 patients and 15 healthcare professionals) contributed to the development of an educational patient leaflet called Sssssst. How do you sleep (at night)? Out of 30 professionals who received the printed leaflet for use in practice, 17 provided feedback after six months. Generally, the leaflet was well received. Visual design aspects stimulated use in practice.

DISCUSSION

Written and visual materials aid primary care professionals to educate patients on sleep and insomnia. This supporting tool also stimulates self-management in patients. Although inspiring and educational for all stakeholders, a co-design approach is no guarantee for the product to "fit all".

Assessment of the Quality of Saudi Patient Information Leaflets (PILs) Based on the Accuracy of Physical Description and Frequency of Solid Dosage Forms

The physical description of dosage forms is one of the most important considerations in avoiding patient confusion and minimizing medication errors. This study aimed to determine the quality and accuracy of the physical descriptions in patient information leaflets (PILs). This cross-sectional study constituted a total of 200 drugs and PILs that were randomly selected, by pharmacy students, from Al-Dawaa community pharmacies in the Hail region of Saudi Arabia, from January 2021 to July 2021. The drugs and PILs were thoroughly evaluated in accordance with the Gulf Cooperation Council (GCC) guidelines for PILs. The accuracy screening of the total solid dosage forms (capsules + tablets) revealed that 45% showed complete accuracy and compliance, 1.5% showed poor accuracy and compliance, and 53% showed no accuracy and no compliance with the GCC guidelines and the Saudi Food and Drug Authority (SFDA) guidelines. In the frequency test, color, shape, and imprints accounted for 95.6%, 79.1%, and 73.6%, respectively. However, the size of the dosage form was the least (2.2%) used physical description feature. These findings recommend pharmaceutical companies to pay more attention to the written physical description in their PILs. Additionally, the process of PIL approval should be optimized, evaluated, and updated systematically to ensure that they contain the essential information.

Thai Patients' Drug Safety Knowledge and Perceptions Relating to Different Forms of Written Medicine Information: A Comparative Study

PURPOSE

The aim of the study was to evaluate the medication safety knowledge, quality of the written medicine information (WMI), and perceptions of taking the medicines in patients receiving package inserts (PIs) in comparison with patient information leaflets (PILs).

METHODS

A cross-sectional, comparative study was conducted from December 2020 to May 2021 at two university hospitals in Thailand. Outpatients who visited the pharmacy departments and were prescribed one of the three medicines: atorvastatin, celecoxib, or metformin were randomly selected by a permuted block randomization. The medication safety knowledge was measured using a set of validated and closed questions. The quality of the WMI was measured by the Consumer Information Rating Form (CIRF). Satisfaction with information and perceptions of the benefits and risks of medications were rated by the participants using a visual analog scale (0 to 10).

RESULTS

Of the 1150 invited patients, 750 completed the questionnaires (65.2%). A higher proportion of respondents with high level of medication safety knowledge was found in those reading the PILs than the PIs (44.5% and 20.8%, respectively). The type of leaflet received was a significant predictor of the high knowledge level (p < 0.001). The mean CIRF scores were significantly higher among those reading the PILs than the PIs (p < 0.001). Patients reading the PILs were also more satisfied with the information and had more positive perceptions of the benefits from taking medicines and intention to adhere than those reading the PIs. Patients' perceptions of risks after reading both leaflets were moderate (median score = 5.0), with the PIL group having slightly more concern about risks than the PI group.

CONCLUSION

The PILs showed superior effectiveness to the PIs in enhancing knowledge about medication safety, providing greater satisfaction with the information, and positive perceptions of benefit and intention to comply with the medications. PILs should be provided more frequently to patients receiving medicines than PIs.

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.

Development and psychometric validation for evaluating written medicine information in Thailand: The Consumer Information Rating Form

OBJECTIVE

To translate and validate the consumer information rating form (CIRF) for use in Thai populations.

DESIGN

The development of the CIRF was carried out in two phases: translation process and cognitive interview, and psychometric testing.

SETTING

A university hospital and a tertiary hospital in northeast Thailand.

PARTICIPANTS

150 outpatients from medicine department: 30 for phase 1 and 120 patients for phase 2 study.

METHODS

The CIRF was translated with cultural adaptation into Thai using cognitive interview technique in a sample of outpatients. A larger sample of outpatients then completed the CIRF in relation to either a package insert (PI) or a patient information leaflet (PIL) for one of three medicines: atorvastatin, celecoxib and metformin. Construct validity was assessed using principal component analysis (PCA) and internal consistency using Cronbach's α coefficient. Known group validity was assessed by comparing mean consumers' ratings for PIs and PILs.

RESULTS

Thirty participants engaged in the cognitive interview and 120 participants completed the CIRF. The PCA found the 17 items of the CIRF were extracted into three factors: comprehensibility, utility and design quality scales, mirroring the original. Cronbach's α for the overall scale (0.904) indicated good internal consistency. Known-group validity demonstrated significant differences in consumers' rating between PIs and PILs for almost all items (p<0.001).

CONCLUSION

Thai version of CIRF had acceptable validity and reliability for Thai consumers' ratings of written medicine information. The CIRF could be of practical use in the process of developing medicine information to ensure consumers' comprehension and their usefulness.

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.

Evaluation of Patient's Knowledge of Atorvastatin Information in Patient Information Leaflets: A Pre-Post Intervention Study in Thailand

PURPOSE

This study aimed to evaluate the effect of using atorvastatin PIL on patients' medication knowledge, perceptions of the PIL usefulness, their anxiety about the medication, and factors related to these aspects.

PATIENTS AND METHODS

A pre-post intervention study was conducted in outpatients at a university hospital. Patients prescribed atorvastatin were enrolled using systematic random sampling. Participants were asked to complete Self-Administered Questionnaire to assess atorvastatin knowledge at baseline. An atorvastatin-PIL produced by the manufacturer was introduced to the participants as the intervention. One month after receiving the PIL, the participants were re-assessed. Ten questions were developed to assess atorvastatin knowledge and visual analog scale (VAS) was used to assess perceived benefits of using the PIL and patient anxiety about the medication. Multiple linear regression was used to assess the related factors.

RESULTS

Of 450 questionnaires distributed, 370 were returned. Atorvastatin knowledge significantly increased with mean score of 5.06±1.92 at baseline to 8.34±1.79 at 1-month after intervention. Reading all sections of the PIL (p=0.017) and working for civil service (p=0.006) were associated with higher knowledge scores at baseline and after intervention. Low educational level was associated with lower knowledge scores at baseline (p=0.002), but experience of allergy (p=0.042) was associated with higher knowledge scores after the intervention. Patients had high level of perceived usefulness from the PIL (average scores=8.87±1.83) and low level of anxiety (average scores=3.69±3.06). Reading all sections of the PIL (p=0.007) and taking more than 5 medications (p=0.012) were related to perceived usefulness of the PIL. Females (p<0.001) and herbal supplement users (p=0.048) were related to anxiety about the medication.

CONCLUSION

PILs could improve medication knowledge in patients. Patients' perceptions of benefits of PILs were high and anxiety about medication was low. Use of PILs should be encouraged to improve patients' knowledge and appropriate use of medications.

Patients' Experiences and Perspectives of Receiving Written Medicine Information About Medicines: A Qualitative Study

PURPOSE

Written medicine information informs patients about the benefits and risks of medicines and supports their safe and effective use. In Thailand, patient information leaflets (PILs) are not obligatory and therefore not routinely supplied. This study aimed to explore the experiences and information needs of patients, their views on PILs and the likely impact of PILs on their knowledge, perceptions and behaviors towards medicines. These factors are important to establish the value of PILs.

METHODS

Semi-structured interviews with outpatients who received simvastatin or atorvastatin were conducted exploring their experiences of receiving medicine information, their views on the utility of and need for PILs, the impact of PILs on their behaviors, and recommendations for how PILs could be improved. All interviews were audio-recorded, transcribed verbatim, and analyzed using a framework approach.

RESULTS

Thirty interviews were conducted from which four themes emerged: experience of receiving medicine information, views of package inserts and PILs, impact of PILs on knowledge, perceptions and behaviors, and patients' need for medicine information. Most participants received verbal information from healthcare professionals, as well as written information. Verbal information was perceived as being particularly useful to inform about changes to medicine regimens or the long-term adverse effects of medicines. Patients perceived that the PILs had influenced their knowledge about medicines, and also their behaviors including safety awareness, adherence, and engagement with healthcare professionals. Participants suggested that the information in electronic format could provide an additional resource. Some changes to improve the content and general format of the PIL were identified.

CONCLUSION

PILs are perceived as useful by patients and met their information needs, although they were viewed as an adjunct to verbal advice provided by healthcare professionals. PILs influenced patients' medicine taking behaviors and encouraged sharing of information with their physicians.

Evaluation of the community pharmacists' performance in the screening of non-steroidal anti-inflmmatory drugs risks in Saudi Arabia

OBJECTIVES

To assess community pharmacists' knowledge and practices regarding screening risk factors and providing safety information about the use of non- steroidal anti-in ammatory drugs (NSAIDs) to patients.

METHODS

Cross-sectional and a self-administered questionnaire-based study was conducted over a 4-month period (May-August 2019) with selected community pharmacies in Jeddah, Saudi Arabia. The questionnaire composed of demographic data and the pharmacist's role in supplying NSAIDs.

RESULTS

The majority of participating community pharmacists dispense NSAIDs. However, many did not apply relevantly good communication skills such as seeking information about concomitant drugs (42.5%) or providing advice on managing any adverse side effects of taking NSAIDs (39.1%). Most of the community pharmacists also did not provide relevantly good communication about risk factors. The most common screening risk factors mentioned were a history of pregnancy and breastfeeding (84.2%) followed by being at an older age (74.5%) or a history of a gastrointestinal ulcer (71.5%).

CONCLUSION

Community pharmacists in Saudi Arabia need to appropriately screen their patients for adverse drug reactions and the ectively communicate the risks of using NSAIDs. The Saudi Regulatory Authority could endorse several approaches to apply a good strategy for improving the dispensing practices in community pharmacies, communication and awareness of risk factors especially in high-risk patients who are taking NSAIDs.

Survey of healthcare professionals' practices, expectations, and attitudes towards provision of patient information leaflets in Thailand

Background Patient information leaflets are an important source of medicine information for patients. In Thailand, there is a lack of studies exploring activities of healthcare professionals and their attitudes towards provision of patient information leaflets. Objectives This study aimed to survey healthcare professionals' practices on provision of medicine information, expectations of, attitudes towards provision of patient information leaflets and factors influencing these. Setting Two university hospitals in Thailand. Methods A self-completion questionnaire was distributed to chiefs of departments for further distribution to staff. A stratified sample of physicians and nurses was invited, while all pharmacists were invited to ensure sufficient numbers for comparison. Main outcome measure Healthcare professionals' practices on provision of medicine information, expectations of, attitudes towards provision of patient information leaflets. Results Of the total 981 healthcare professionals invited, 493 responded (50.3% response rate). The number of respondents aware of patient information leaflets was 270 (57.6%). Of these, only 44.4% had ever given patient information leaflets to patients. Pharmacists provided patient information leaflets more frequently than other healthcare professionals. The expectation for patient information leaflets to be available was high; mean score 7.9 ± 2.31 of possible 10. Most respondents had positive attitudes towards providing patient information leaflets to patients (58.2%). Respondents who were aware of patient information leaflets availability were more likely to have a positive attitude (OR 0.543, p = 0.002). Level of education, time spent in direct care and being aware of patient information leaflets were factors associated with healthcare professionals' attitudes. Conclusion Limited number of healthcare professionals had provided patient information leaflets to patients but most had positive attitudes regarding the usefulness of patient information leaflets for patients. Increased availability and use of patient information leaflets should be promoted.

Development of consumer information leaflets for deprescribing in older hospital inpatients: a mixed-methods study

OBJECTIVE

To develop information leaflets for older inpatients and/or their carers to support deprescribing of antipsychotics, benzodiazepines/Z-drugs and proton pump inhibitors (PPIs).

DESIGN

An iterative mixed-methods approach involving face-to-face user testing and semi-structured interviews was performed over three rounds with consumers and hospital health professionals.

SETTING

Sydney, New South Wales, Australia.

PARTICIPANTS

Thirty-seven consumers (or their carers) aged 65 years or older admitted to hospital in the previous 5 years and taking at least one regular medicine (not the medicine tested) completed user testing. Health professionals included a convenience sample of seven pharmacists and five doctors.

METHODS

The antipsychotic leaflet was tested in round 1 (consumers, n=10) and revised and retested in round 2 (consumers, n=9; health professionals, n=5). Findings from rounds 1 and 2 informed the design of the benzodiazepine/Z-drug and PPI leaflets tested in round 3 (benzodiazepine/Z-drug consumers, n=9; health professionals, n=7; PPI consumers, n=9). Findings from round 3 informed the final design of all leaflets. Consumer user testing involved 12-13 questions to evaluate consumers' ability to locate and understand information in the leaflet. Usability by health professionals was assessed using the System Usability Scale (SUS).

RESULTS

At least 80% of consumers correctly found and understood the deprescribing information in the leaflets (9 of 12 information points in round 1 (antipsychotic); 10 of 12 in round 2; 12 of 13 (benzodiazepine/Z-drug) and 11 of 12 (PPI) in round 3). Consumers perceived the leaflets to be informative, well-designed and useful aids for ongoing medication management. The SUS scores obtained from health professionals were 91.0±3.8 for the antipsychotic leaflet and 86.4±6.6 for the benzodiazepine/Z-drug leaflet, indicating excellent usability.

CONCLUSIONS

Understandable and easy-to-use consumer information leaflets were developed and tested by consumers and health professionals. The feasibility and utility of these leaflets to support deprescribing at transitions of care should be explored in clinical practice.
