Factors influencing consumer use of written drug information

Internet Use for Obtaining Medicine Information: Cross-sectional Survey

BACKGROUND

The internet is increasingly being used as a source of medicine-related information. People want information to facilitate decision-making and self-management, and they tend to prefer the internet for ease of access. However, it is widely acknowledged that the quality of web-based information varies. Poor interpretation of medicine information can lead to anxiety and poor adherence to drug therapy. It is therefore important to understand how people search, select, and trust medicine information.

OBJECTIVE

The objectives of this study were to establish the extent of internet use for seeking medicine information among Norwegian pharmacy customers, analyze factors associated with internet use, and investigate the level of trust in different sources and websites.

METHODS

This is a cross-sectional study with a convenience sample of pharmacy customers recruited from all but one community pharmacy in Tromsø, a medium size municipality in Norway (77,000 inhabitants). Persons (aged ≥16 years) able to complete a questionnaire in Norwegian were asked to participate in the study. The recruitment took place in September and October 2020. Due to COVID-19 restrictions, social media was also used to recruit medicine users.

RESULTS

A total of 303 respondents reported which sources they used to obtain information about their medicines (both prescription and over the counter) and to what extent they trusted these sources. A total of 125 (41.3%) respondents used the internet for medicine information, and the only factor associated with internet use was age. The odds of using the internet declined by 5% per year of age (odds ratio 0.95, 95% CI 0.94-0.97; P=.048). We found no association between internet use and gender, level of education, or regular medicine use. The main purpose reported for using the internet was to obtain information about side effects. Other main sources of medicine information were physicians (n=191, 63%), pharmacy personnel (n=142, 47%), and medication package leaflets (n=124, 42%), while 36 (12%) respondents did not obtain medicine information from any sources. Note that 272 (91%) respondents trusted health professionals as a source of medicine information, whereas 58 (46%) respondents who used the internet trusted the information they found on the internet. The most reliable websites were the national health portals and other official health information sites.

CONCLUSIONS

Norwegian pharmacy customers use the internet as a source of medicine information, but most still obtain medicine information from health professionals and packet leaflets. People are aware of the potential for misinformation on websites, and they mainly trust high-quality sites run by health authorities.

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.

Electronic Package Leaflets for Vaccines: What Are People’s Perceptions in Italy?

In Italy, the paper package leaflet (PPL) is the official document that is approved by the Italian Medicines Agency (AIFA) for each medicine. PPLs of all medicines, including vaccines, are freely available online by accessing the AIFA website. To investigate people’s attitudes toward possible access to the PPLs of vaccines and the acceptability of switching to an electronic package leaflet (e-leaflet) in the future, we surveyed three target groups (pregnant women, young parents, and older people) in Italy, via an online survey. We collected 321 questionnaires from the cohorts, which comprised 104 pregnant women, 105 young parents, and 112 older people. The results indicate in all target groups that health care professionals (HCPs) do not usually offer the vaccine PPL during the vaccination session: only about 10.7% of respondents receive the PPL without asking for it, with pregnant women receiving it the most frequently. The acceptance rate for switching from a PPL to an e-leaflet is fairly high in all target groups (76.9% in pregnant women, 81.9% in young parents, and 66.1% in the elderly), especially if the option exists to request a paper print, to make sure that people with a low level of digital skills can access the PPL information as well. HCPs have an important role in ensuring access to the PPLs of vaccines. HCPs should be trained to inform their patients about the different options for accessing the PPLs (as well as online access) to increase their patients’ knowledge and satisfaction.

An evaluation of newborn hearing screening brochures and parental understanding of screening result terminology

OBJECTIVE

To assess the suitability of newborn hearing screening brochures by evaluating current state-level brochures and pregnant people's understanding of screening result terminology.

DESIGN

In Study 1, state-level brochures were evaluated based on readability, design, picture appropriateness, and use of the word "refer." In Study 2, pregnant people completed a questionnaire that queried their understanding of and expected anxiety about three newborn hearing screening outcomes ("refer," "did not pass," and "pass").

STUDY SAMPLE

In Study 1, 59 newborn hearing screening brochures were analysed. In Study 2, 43 pregnant people completed surveys during a prenatal appointment.

RESULTS

Most of the brochures were found deficient on at least one element. Thirty percent of brochures used the word "refer" to indicate a hearing screening failure; yet, fewer than half of participants understood its meaning. Ratings of expected anxiety were highest in response to the term "did not pass."

CONCLUSIONS

Based on four study criteria of brochure suitability, 88% of available state-level newborn hearing screening brochures should be modified to make them readily understandable by a broad educational demographic. Discretion in use of the term "refer" should be made when indicating screening results, because the term is not readily understood.

Presentation of benefits and harms of antidepressants on websites: A cross-sectional study

BACKGROUND:

Many people use the Internet for obtaining information about their medications.

OBJECTIVE:

To investigate whether information about antidepressants on popular websites reflects the scientific evidence and enables people to make informed choices.

METHODS:

Cross-sectional study using a checklist with 14 predefined criteria of 39 websites from 10 countries.

RESULTS:

All 39 websites mentioned the benefits of antidepressants. Twenty-nine (74%) websites attributed depression to a “chemical imbalance” or claimed they could fix an imbalance. Sexual dysfunction was mentioned as a harmful effect on 23 (59%) websites while five (13%) mentioned emotional numbing. Twenty-five (64%) stated that antidepressants may cause increased suicidal ideation, but 23 (92%) of them contained incorrect information, and only two (5%) websites noted that the suicide risk is increased in people of all ages. Twenty-eight websites (72%) warned patients about withdrawal effects but only one stated that antidepressants can be addictive.

CONCLUSIONS:

None of the websites met our predefined criteria. The information was generally inaccurate and unhelpful and has potential to lead to inappropriate use and overuse of antidepressants and reduce the likelihood that people will seek better options for depression like psychotherapy.

Assessing the Readability of Medicine Information Materials: The Case of Tikur Anbessa Specialized Hospital - Mixed Approach

BACKGROUND

Patients are frequently provided with medicine information materials (MIMs). Rendering medicine information through written material is a reliable method. Readability is an important attribute of written material that can affect the reader's ability to comprehend. Patient's perception can also affect the comprehensibility of written MIMs.

OBJECTIVE

The objectives of the study were to assess the readability of medicine information in Tikur Anbessa Specialized Hospital (TASH); and assessing patients' perception and understanding of medicine information materials.

METHODS

This was a cross-sectional study conducted from September 21, 2019 to November 24, 2020, at TASH. Quantitative and qualitative data collection approaches were used in this research. The readability value of each material was determined in accordance with the Flesch Reading ease scores (FRE) and Flesch-Kincaid Grade Level (FKGL). The tools compute readability based on an average number of syllables per word and an average number of words per sentence. FRE provides scores from 0 to 100; higher scores mean easily comprehensible while FKGL sets grade levels for written texts. A structured interview was administered with questions about how MIMs had been used, and was analyzed qualitatively.

RESULTS

The results of this research showed low readability scores of MIMs found in TASH. Most patients do not get MIMs and are unaware of how to use them. They are interested to receive and read medicines information from pharmacists and physicians. Moreover, most of them preferred information through both verbal and written forms.

CONCLUSION

The readability levels of selected MIMs obtained from TASH are found to be not compliant with the patients' needs. This might be worsening their health outcomes and resulting in poorer use of healthcare services.

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.

Adherence to the oral contraceptive pill: the roles of health literacy and knowledge

OBJECTIVE

The oral contraceptive pill is the most widely used method of contraception and when adhered to perfectly is 99% effective at preventing pregnancy. However, adherence to the pill is relatively low. Knowledge has shown to be important in continuation of the pill, and previous research shows the importance of health literacy in adhering to medication in chronic illnesses, but its role has yet to be explored in this behavior.

METHODS

This cross-sectional study examined the associations between health literacy, knowledge of the pill and adherence, as well as the predictive ability of these two variables and their interaction, in predicting adherence. Recruited through CloudResearch, 193 women (M age = 32.63 years, SD = 5.98) residing in the United States completed the Health Literacy Skills Instrument - Short Form, a previously validated measure of oral contraceptive pill knowledge and the Medication Adherence Report Scale.

RESULTS

Results showed a strong positive correlation between health literacy and adherence (r = .76) and moderate associations between health literacy and knowledge (r = .42), and knowledge and adherence (r = .42). The final model of the hierarchical multiple regression accounted for 59.8% of variance in adherence, with health literacy (β = .69) and length of time taking the pill (β = .13) the only significant predictors of adherence.

CONCLUSION

Family planning clinics should consider assessing the patient's health literacy skills before prescribing the pill to ensure patients fully understand the requirements.

Document-Engineering Methodology in Health Care: An Innovative Behavioral Science–Based Approach to Improve Patient Empowerment

Engaging patients in their treatment and making them experts of their condition has been identified as a high priority across many medical disciplines. Patient empowerment claims to improve compliance, patient safety, and disease outcome. Patient empowerment may help the patient in shared decision making and in becoming an informed partner of the health care professional. We consider patient empowerment to be in jeopardy if written medical information for patients is too complex and confusing. We introduce document-engineering methodology (DEM) as a new tool for the health care industry. DEM tries to implement principles of cognitive science and neuroscience-based concepts of reading and comprehension. It follows the most recent document design techniques. DEM has been used in the aviation, mining, and oil industries. In these very industries, DEM was integrated to improve user performance, prevent harm, and increase safety. We postulate that DEM, applied to written documents in health care, will help patients to quickly navigate through complex written information and thereby enable them to better comprehend the essence of the medical information. DEM aims to empower the patient and help start an informed conversation with their health care professional. The ultimate goals of DEM are to increase adherence and compliance, leading to improved outcomes. Our approach is innovative, as we apply our learning from other industries to health care; we call this cross-industry innovation. In this manuscript, we provide illustrative examples of DEM in three frequent clinical scenarios: (1) explaining a complex diagnosis for the first time, (2) understanding medical leaflet information, and (3) exploring cannabis-based medicine. There is an urgent need to test DEM in larger clinical cohorts and for careful proof-of-concept studies, regarding patient and stakeholder engagement, to be conducted.

Experiences and Views of Medicine Information Among the General Public in Thailand

PURPOSE

Written and electronic medicine information are important for improving patient knowledge and safe use of medicines. Written medicine information in Thailand is mostly in the form of printed package inserts (PIs), designed for health professionals, with few medicines having patient information leaflets (PILs). The aim of this study was to determine practices, needs and expectations of Thai general public about written and electronic medicine information and attitudes towards PILs.

PATIENTS AND METHODS

Cross-sectional survey, using self-completed questionnaires, was distributed directly to members of the general public in a large city, during January to March 2019. It explored experiences of using information, expectations, needs and attitudes, the latter measured using a 10-item scale. Differences between sub-groups were assessed, applying the Bonferroni correction to determine statistical significance.

RESULTS

Of the total 851 questionnaires distributed, 550 were returned (64.2%). The majority of respondents (88%) had received PIs, but only a quarter (26.2%) had received PILs. Most respondents (78.5%) had seen medicine information in online form. High educational level and income increased the likelihood of receiving PILs and electronic information. The majority of respondents (88.5%) perceived PILs as useful, but 70% considered they would still need information about medicines from health professionals. Indication, drug name and precautions were the most frequently read information in PIs and perceived as needed in PILs. Three-quarters of respondents would read electronic information if it were available, with more who had received a PIL having previously searched for such information compared to those who had not. All respondents had positive overall attitudes towards PILs.

CONCLUSION

Experiences of receiving PILs and electronic medicine information in Thailand are relatively limited. However, the general public considered PILs as a useful source of medicine information. Electronic medicine information was desired and should be developed to be an additional source of information for consumers.

Medicine package inserts from the users' perspective: are they read and understood?

INTRODUCTION

The written information on medicines has been acknowledged as an important tool for health education.

OBJECTIVE

To analyze the use and understanding of medicine package inserts by users and assess sociodemographic and medical factors associated with their comprehension.

METHOD

Data in this analysis are part of the PNAUM National Survey - a cross-sectional population-based study conducted in Brazil. Descriptive statistics and the Pearson χ2 tests were performed to compare proportions between sociodemographic and medical characteristics, as well as use and understanding of medicine package inserts.

RESULTS

A total of 28.427 individuals responded to questions related to medicine package inserts. From these, 59.6% (95%CI 57.7 - 61.5) said they usually read the inserts, and 98.4% (95%CI 98.0 - 98.8) considered them necessary. Among people who read the medicine package inserts, more than half indicated difficulties with legibility (57.4%; 95%CI 55,2 - 59,6) and readability (54.1%; 95%CI 52.1 - 56.1). People from a lower education level reported greater difficulty in understanding them.

CONCLUSION

The larger portion of the population usually read medicine package inserts. Nevertheless, people have difficulty in reading and understanding them.

Users' preferences and perceptions of the comprehensibility and readability of medication labels

OBJECTIVE

To evaluate the labeling preferences of medication users and characterize their perceptions of the comprehensibility and readability of medication labels.

METHODS

We conducted a population-based cross-sectional study of medication users aged 18 years or older in 10 Brazilian capital cities. Perceptions of the comprehensibility and readability of medication labels in relation to sociodemographic characteristics were evaluated by Poisson regression models with robust variance. Labeling preferences were assessed through questions addressing possible improvements and through the use of digitally simulated packages.

RESULTS

Of 6,255 medication users interviewed, more than half found it difficult or very difficult to read (50.8%) and/or understand (52.0%) medication labels. Difficulties were more pronounced for participants aged 40 years or older, with lower levels of education, and non-whites. Increasing the font size (93.7%), describing the indications for use (95.9%) and contraindications (95.6%) on the label, and highlighting the expiration date (96.3%) were the most widely accepted improvements. In the evaluation of simulated packages, users preferred factors that improved readability, such as increased font size, use of graphic elements and color to highlight the concentration of the active ingredient, and contrast between the font color and background. The new simulated package design, with increased font size, color to highlight the concentration and contrast between the font color and background, was preferred over the standard design by 77.0% of participants.

CONCLUSION

Based on users' perceptions, increased font size and use of graphic elements and color to emphasize critical information, such as expiration date and concentration, are factors that contribute to making medication labels clearer to users. Pharmaceutical industries and policy makers should consider these items when developing labels and defining policies on this issue.

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

INTRODUCTION

Thai patients do not routinely receive patient information leaflets (PILs) with medicines, so awareness of safety issues is low. This study aimed: i) to develop Thai PILs for NSAIDs and subject these to user-testing, and ii) to assess the potential value of PILs from the patient perspective and effect on patient knowledge.

METHODS

Four PILs for NSAIDs were developed and subjected to multiple rounds of user-testing by the general public. Self-administered questionnaires were distributed to orthopaedic out-patients prescribed one of these NSAIDs, assessing knowledge before and after providing a PIL. The follow-up questionnaire also sought use of and views on the PILs using a visual analogue scale (VAS).

RESULTS

1,240 baseline questionnaires were completed; only 13.5% of patients had good knowledge. 688 patients returned follow-up questionnaires (55.5%), of whom75% had good knowledge. In patients completing both questionnaires, mean knowledge score increased from 6.22±1.40 to 8.42±1.41 (p<0.001). Patients with high educational levels had high baseline scores (OR = 2.728) and showed greatest improvement in knowledge (OR = 5.628). 90% (625) of follow-up respondents indicated they read all information in the PILs. All also agreed that these PILs should distributed to all patients taking NSAIDs. The median VAS score for usefulness was 9.3 (IQR 8.6-10.0).

CONCLUSIONS

User-testing of PILs was feasible in a Thai population and enabled the development of acceptable and desirable PILs. PILs could improve patients' knowledge about their medicine, particularly among those with higher educational level. User-tested PILS could meet the need for more written medicine information.

Patients’ views of general practitioners’ provision of medicine information leaflets

ABSTRACT INTRODUCTIONGiving patients medicine information leaflets with oral information could help improve patient understanding about their medicines. Some health professionals believe patients do not want to receive leaflets or find them too difficult to understand so do not provide them. AIMTo investigate Dunedin general practitioners’ (GPs) provision of medicine information leaflets from patients’ reports and to examine patient views about the leaflets provided. METHODSPatients collecting prescriptions from community pharmacies in Dunedin, New Zealand, between December 2016 and February 2017 were asked to complete a survey. Responses were entered into SurveyMonkey and data were exported into Excel for analysis. RESULTSOf the 151 survey respondents, over three-quarters (79%) did not receive a medicine information leaflet from their GP in the last 6 months, although most believed it important to receive one. Many participants felt that leaflets improved their knowledge and helped them take their medication correctly. Most participants liked the leaflets they received, although over half (60%) would like a short summary leaflet. Patients did not commonly search for more information than their GP provided. DISCUSSIONSome patients may not seek further information about their medicines other than during consultation. Although rarely given, most participants who received leaflets from their GP appreciated them. Most participants read and understood leaflets they were provided, although ready access to a one- to two-page summary leaflet may be preferable. Technology could enable GPs to easily provide leaflets to patients in their care.

Survey of outpatients' use and needs of patient medicine information leaflets in Thailand

Background Patient information leaflets are important sources of medicine information. Regulations of patient information leaflet provision varies among country. Little is known regarding patients' behavior and expectation on use of patient information leaflets. Objectives To explore patients' use of either package inserts or patient information leaflets and to survey patients' expectations and needs on use of patient information leaflets and their associated factors. Setting Two university hospitals in Thailand. Methods Cross-sectional study using self-administered questionnaires distributed to outpatients over a 3-month period. Participants were selected through systematic random sampling. Logistic regression was used for data analysis. Main outcome measure Patient use of medicine information. Visual Analogue Scale scores for patient needs and their expectation of knowledge gains from using patient information leaflets. Results The response rate was 77.0%. Most respondents had received package inserts (91.3%) with 59.4% reporting that they sometimes read them. While most respondents had not previously known about patient information leaflets (75.9%), 97.3% reported that patient information leaflets would be useful. Respondents scored their needs and expected knowledge gains after reading patient information leaflets as 9.68 ± 0.97 and 9.64 ± 0.99, respectively. Previous experience with package inserts was associated with increased patient need scores (p = 0.002) and higher expected knowledge gains from use of patient information leaflets (p = 0.037). In addition, patients who had not previously known about patient information leaflets had higher expectations of knowledge gains (p = 0.016). Conclusion Overall, patients showed good behavior on reading package inserts. Although many patients were not previously aware of patient information leaflets, they realized the importance. Hence, patient information leaflets should be developed and provided to Thai patients.

Patient information leaflets on psychotropic drugs: opinions and use by psychiatrists

Aims and Method

To assess circumstances and frequency of use, opinions and suggestions for improvement from psychiatrists in a teaching hospital on UK Psychiatric Pharmacy Group patient information leaflets for psychotropic drugs. We also sought information from psychiatrists regarding use of alternate sources of information provision for their patients on psychotropic drugs. A questionnaire was designed, piloted and distributed.

Results

Sixty-one psychiatrists were approached, of whom 49 (80%) responded. the most common indications for use were when initiating a new treatment and when information is sought by the individual or their carers. the most common reason for not using these leaflets was lack of awareness of their existence. Although 33 (67%) responders were of the opinion that these leaflets were useful for patients, only a small proportion was using them frequently.

Clinical Implications

Our study suggested increasing awareness among psychiatrists to encourage the use of patient information leaflets. Various other themes to improve their use also emerged including easy accessibility to the patient information leaflets, modification in the content and structure, and recording the provision of patient information leaflets in the case records.

Comparative analysis of package inserts of local and imported antihypertensive medications in Palestine

BACKGROUND

Package inserts (PIs) as a reliable reference for patients and health care providers should provide accurate, complete and up-to-date information. The purpose of the current study is to assess and compare the PIs of antihypertensive agents locally produced in Palestine and their imported counterparts.

METHODS

Thirty-five PIs were assessed for the presence of 31 information statements using a scoring method. Word counting of 20 headings and subheadings was used to evaluate and compare local and imported PIs for information quantity.

RESULTS

None of the analysed PIs fulfilled the criteria. All of them included the brand name, active ingredients, indications, directions for use, adverse drug reactions, drug-drug interactions, pregnancy and lactation considerations, and storage. Whereas none of them, either local or imported PIs, included the shelf life and instructions to convert tablets or capsules into liquid forms. Additionally, only one (5%) imported and no (0%) local PIs mentioned the duration of therapy. Moreover, 93.4% of local PIs were deficient in areas regarding the inactive ingredients and date of last revision, and 86.7% did not mention the drug dose and possibility of tablet splitting. Furthermore, the maximum dose was not indicated in 90% of imported and 86.7% of local PIs. In general, imported PIs contained more detailed information than their local counterparts, where the range of differences in medians between the local and imported PIs was from 1.5-fold for pregnancy considerations to >42.00-fold for the effect on the ability to drive and use machines.

CONCLUSIONS

The findings of this study revealed the superiority of imported over local PIs in both quality and quantity of information provided. This emphasises the need for appropriate measures to be taken by the Ministry of Health and local manufacturers to ensure efficiency of local PIs in providing accurate, complete and up-to-date information.

Readability and Comprehensibility of Patient Information Leaflets for Antidiabetic Medications in Qatar

Background:The readability and comprehensibility of the patient information leaflets (PILs) provided with antidiabetic medications are of questionable standards; this issue negatively affects adherence to drug therapy, especially in patients with limited literacy skills. Objective: To evaluate the readability and comprehensibility of PILs supplied with medications used for the treatment of type 2 diabetes mellitus in Qatar. Methods: All PILs of the antidiabetic medications in Qatar were evaluated using the Flesch Reading Ease (FRE) score for readability. The Flesch-Kincaid Grade Level, Gunning-Fog Index, and SMOG Grading were used to estimate the comprehensibility of PILs in terms of school grade levels. Results: A total of 45 PILs were evaluated: 32 (71.1%) PILs of brand-name products and 13 (28.9%) for generics. Nine (20%) of the PILs were in English only; 8 (17.8%) were in English, Arabic, and French; and 28 (62.2%) were in English and Arabic. The mean FRE score was 37.71 (±15.85), and the most readable PIL had FRE score of 62. The mean scores for the comprehensibility evaluations were 10.96 (±2.67), 15.02 (±2.52), and 11.41 (±1.6) for the Flesch-Kincaid Grade Level, Gunning-Fog Index, and SMOG Grading, respectively. The most commonly used antidiabetic medication was metformin with 1372.9 (±552.9) as PILs' mean number of words. Conclusion: Only 2.2% of PILs had acceptable readability scores. All PILs could be comprehended by at least an 11th grade student, which exceeds the recommended grade level for health-related materials. Approximately 20% of these PILs were in English only and were not readable by most patients.

Patients' Use and Perception of Medication Information Leaflets

Background:

Federal law mandates that at least 95% of patients receive useful written information with new medications. Recent data concerning whether patients read such leaflets are lacking.

Objectives:

To evaluate whether patients read non–manufacturer-developed leaflets and assess patients' opinions concerning the understandability and usefulness of these leaflets.

Methods:

Patients were surveyed at 32 community pharmacies in the New York City metropolitan area. The main outcome measures were the percentage of patients who read the leaflet provided with new and refilled medications and the perceived understandability and usefulness of the leaflet. Descriptive statistics were used to analyze the results.

Results:

A total of 307 patients were surveyed. For leaflets provided with new medications, 151 (49.2%), 65 (21.2%), 49 (16.0%), and 42 (13.7%) reported reading the leaflets always, often, seldom, or never, respectively. For refilled medications, 64 (21.6%), 41 (13.9%), 78 (26.4%), and 113 (38.2%) of the 296 respondents reported reading the leaflets always, often, seldom, or never, respectively. Of 267 patients who read the leaflets provided with new or refilled prescriptions at least seldom, 258 (96.6%) responded to the question concerning its understandability and 257 (96.3%) responded to the question concerning its usefulness. One hundred forty-five (56.2%), 89 (34.5%), 22 (8.5%), and 2 (0.8%) reported that the leaflet was very easy, somewhat easy, somewhat difficult, and very difficult to understand, respectively, and 164 (63.8%), 90 (35.0%), and 3 (1.2%) reported that the leaflet was very useful, somewhat useful, and not useful, respectively.

Conclusions:

Approximately two-thirds of the patients surveyed reported reading the leaflets provided with new medications at least often. The majority reported the leaflets to be useful and easy to understand. Pharmacists should advocate reading the leaflet and promote it as a useful resource. The leaflet should not replace the pharmacist's obligation to provide verbal counseling.

Low literacy and written drug information: information-seeking, leaflet evaluation and preferences, and roles for images

Background Low-literate patients are at risk to misinterpret written drug information. For the (co-) design of targeted patient information, it is key to involve this group in determining their communication barriers and information needs. Objective To gain insight into how people with low literacy use and evaluate written drug information, and to identify ways in which they feel the patient leaflet can be improved, and in particular how images could be used. Setting Food banks and an education institution for Dutch language training in the Netherlands. Method Semi-structured focus groups and individual interviews were held with low-literate participants (n = 45). The thematic framework approach was used for analysis to identify themes in the data. Main outcome measure Low-literate people’s experience with patient information leaflets, ideas for improvements, and perceptions on possible uses for visuals. Results Patient information leaflets were considered discouraging to use, and information difficult to find and understand. Many rely on alternative information sources. The leaflet should be shorter, and improved in terms of organisation, legibility and readability. Participants thought images could increase the leaflet’s appeal, help ask questions, provide an overview, help understand textual information, aid recall, reassure, and even lead to increased confidence, empowerment and feeling of safety. Conclusion Already at the stages of paying attention to the leaflet and maintaining interest in the message, low-literate patients experience barriers in the communication process through written drug information. Short, structured, visual/textual explanations can lower the motivational threshold to use the leaflet, improve understanding, and empower the low-literate target group.

Evaluation of Web-Based Consumer Medication Information: Content and Usability of 4 Australian Websites

Background

Medication is the most common intervention in health care, and written medication information can affect consumers’ medication-related behavior. Research has shown that a large proportion of Australians search for medication information on the Internet.

Objective

To evaluate the medication information content, based on consumer medication information needs, and usability of 4 Australian health websites: Better Health Channel, myDr, healthdirect, and NPS MedicineWise .

Methods

To assess website content, the most common consumer medication information needs were identified using (1) medication queries to the healthdirect helpline (a telephone helpline available across most of Australia) and (2) the most frequently used medications in Australia. The most frequently used medications were extracted from Australian government statistics on use of subsidized medicines in the community and the National Census of Medicines Use. Each website was assessed to determine whether it covered or partially covered information and advice about these medications. To assess website usability, 16 consumers participated in user testing wherein they were required to locate 2 pieces of medication information on each website. Brief semistructured interviews were also conducted with participants to gauge their opinions of the websites.

Results

Information on prescription medication was more comprehensively covered on all websites (3 of 4 websites covered 100% of information) than nonprescription medication (websites covered 0%-67% of information). Most websites relied on consumer medicines information leaflets to convey prescription medication information to consumers. Information about prescription medication classes was less comprehensive, with no website providing all information examined about antibiotics and antidepressants. Participants (n=16) were able to locate medication information on websites in most cases (accuracy ranged from 84% to 91%). However, a number of usability issues relating to website navigation and information display were identified. For example, websites not allowing combinations of search terms to be entered in search boxes and continuous blocks of text without subheadings.

Conclusions

Of the 4 Australian health information websites tested, none provided consumers with comprehensive medication information on both prescription and nonprescription medications in a user-friendly way. Using data on consumer information needs and user testing to guide medication information content and website design is a useful approach to inform consumer website development.

Patients' views on electronic patient information leaflets

Background:

Information in society and in health care is currently undergoing a transition from paper to digital formats, and the main source of information will probably be electronic in the future.

Objective:

To explore patients’ use and perceptions of the patient information leaflet included in the medication package, and their attitude towards a transition to an electronic version.

Methods:

The data was collected during October to November 2014 among individuals in South-Eastern Sweden, using a questionnaire (n=406, response rate 78%) and interviews (n=15).

Results:

The questionnaire showed that the majority of the respondents (52%) occasionally read the patient information leaflet, 37% always read it, and 11% never read it. Almost half of the patients (41%) were positive towards reading the patient information leaflet electronically while 32% were hesitant and 26% neutral. A majority of the patients would request to get the patient information leaflet printed at the pharmacy if it was not included in the package. There were differences in attitude related to age and gender. The interviews showed that patients had mixed views on a transition to an electronic patient information leaflet. The patients perceived several positive aspects with an electronic patient information leaflet but were concerned about elderly patients.

Conclusion:

Although many were positive towards reading the patient information leaflet electronically, the majority prefer the patient information leaflet in paper form. Providing appropriate and useful eHealth services for patients to access the patient information leaflet electronically, along with education, could prepare patients for a transition to electronic patient information leaflet.

Timing of Administration: For Commonly-Prescribed Medicines in Australia

Chronotherapy involves the administration of medication in coordination with the body's circadian rhythms to maximise therapeutic effectiveness and minimise/avoid adverse effects. The aim of this study is to investigate the "time of administration" recommendations on chronotherapy for commonly-prescribed medicines in Australia. This study also aimed to explore the quality of information on the timing of administration presented in drug information sources, such as consumer medicine information (CMI) and approved product information (PI). Databases were searched for original research studies reporting on the impact of "time of administration" of the 30 most commonly-prescribed medicines in Australia for 2014. Further, time of administration recommendations from drug information sources were compared to the evidence from chronotherapy trials. Our search revealed 27 research studies, matching the inclusion and exclusion criteria. In 56% (n = 15) of the research studies, the therapeutic effect of the medicine varied with the time of administration, i.e., supported chronotherapy. For some medicines (e.g., simvastatin), circadian-based optimal administration time was evident in the information sources. Overall, dedicated studies on the timing of administration of medicines are sparse, and more studies are required. As it stands, information provision to consumers and health professionals about the optimal "time" to take medications lags behind emerging evidence.

Identify practice gaps in medication education through surveys to patients and physicians

BACKGROUND

Effective communication and education formats between health care providers and patients about medication use are associated with patients' satisfaction, recall of information, and eventually their health status. Limited research exists on physician-delivered education interventions, as well as on whether the current content of medication education and delivery formats satisfies the needs of both patients and physicians. Our objective was to identify the practice gaps regarding medication education content and delivery.

METHODS

Separate surveys were obtained from ambulatory care patients presenting to the outpatient pharmacy for medication pickups, and physicians working at the hospital clinics.

RESULTS

A total of 108 patients completed the patient survey, and 116 hospital clinic physicians completed the physician survey. Female patients had a higher degree of concern regarding medication information compared with male patients (4.04±0.65 versus 3.58±0.66, P=0.001). Physicians were less likely to educate patients regarding their medications' on drug-drug interactions (24.3%), drug-food interactions (24.3%), and what to do about their prescriptions if an adverse reaction is experienced (24.3%) during physician-patient encounters. Patients' most desired education format was physician counseling (82.4%) and the second most desired education format was pharmacist counseling (50.9%). Medication device demonstration (7.0%) was the least used educational format delivered to patients by physicians, and patients would like to see an increased education delivery format through medication device demonstration (Method desired [MD] - Method received [MR] =12.0%). Patients would like to see expanded roles of patient focused handout (MD-MR=22.2%), telephone consultation (21.2%), pharmacist counseling (12.9%), the use of medication database embedded within the hospital information system (12.2%) and device demonstration (12.0%).

CONCLUSION

This study illustrates that there are practice gaps in current medication education both in terms of content and delivery format. The study provided valuable information in designing and implementing future education activities that are drivers of good medication use and adherence.

Effects of a TELephone Counselling Intervention by Pharmacist (TelCIP) on medication adherence, patient beliefs and satisfaction with information for patients starting treatment: study protocol for a cluster randomized controlled trial

BACKGROUND

Adherence to medication is often low. Pharmacists may improve adherence, but a one-size-fits-all approach will not work: different patients have different needs. Goal of the current study is to assess the effectiveness of a patient-tailored, telephone-based intervention by a pharmacist at the start of pharmacotherapy aimed at improving medication adherence, satisfaction with information and counselling and the beliefs about medicines.

METHODS/DESIGN

A cluster randomized controlled intervention trial in 30 Dutch pharmacies, randomly assigned to 1 of 2 intervention groups. Each group consists of an intervention arm and an usual care arm. The intervention arm in the first group is the usual care arm in the second group and vice versa. One intervention arm focuses on patients starting with antidepressants or bisphosphonates and the other on antilipaemic drugs or renin angiotensin system (RAS)-inhibitors. The intervention consists of a telephone call by a pharmacist 2 or 3 weeks after a new prescription. A random sample of pharmacies will send questionnaires 3 months after the first prescription. This contains socio-demographic questions, a measure of beliefs about medicines (BMQ), satisfaction with information received (SIMS, abbreviated) and frequency of pharmacy counselling (Consumer Quality Index, CQI, abbreviated). The primary outcome measure will be medication adherence calculated from dispensing records retrieved 12 months after the intervention. Patients' beliefs on medication, perception of the quality of information received and pharmacy counselling are secondary outcomes.

DISCUSSION

The TelCIP study will determine the effectiveness of telephone counselling to improve adherence in patients initiating a new treatment. By measuring satisfaction with information and counselling and beliefs about medication the study will also give clues for the reason of a potential increase in adherence. Finally the study will provide information on which patients are most likely to benefit from this intervention.

TRIAL REGISTRATION

The trial is registered at http://www.trialregister.nl under the identifier NTR3237.

Pharmaceutical information systems and possible implementations of informed consent -- developing an heuristic

BACKGROUND

Denmark has implemented a comprehensive, nationwide pharmaceutical information system, and this system has been evaluated by the Danish Council of Ethics. The system can be seen as an exemplar of a comprehensive health information system for clinical use.

ANALYSIS

The paper analyses 1) how informed consent can be implemented in the system and how different implementations create different impacts on autonomy and control of information, and 2) arguments directed towards justifying not seeking informed consent in this context.

RESULTS AND CONCLUSION

Based on the analysis a heuristic is provided which enables a ranking and estimation of the impact on autonomy and control of information of different options for consent to entry of data into the system and use of data from the system.The danger of routinisation of consent is identified.The Danish pharmaceutical information system raises issues in relation to autonomy and control of information, issues that will also occur in relation to other similar comprehensive health information systems. Some of these issues are well understood and their impact can be judged using the heuristic which is provided. More research is, however needed in relation to routinisation of consent.

Evaluation of medication package inserts in Saudi Arabia

Purpose

The aim of this study was to examine if package inserts (PIs) supplied with prescribed and over-the-counter medications in Saudi Arabia contain information relevant for the safe and appropriate use of these medications.

Methods

Sixty PIs for prescription-only medications (n = 37) and over-the-counter medications (n = 23) were evaluated against a set of safety criteria compiled from the literature.

Results

Analyzed PIs were defective in many aspects. Particularly of concern were unclear dosage instructions, lack of measures to be taken when an administrative error was made, inappropriate presentation of side effects, and lack of measures to be taken if serious side effects occurred.

Conclusion

This study indicated that information relevant to the safe and appropriate use of medications was not uniformly mentioned in the PIs analyzed. To avoid medication errors due to deficits in the current PIs, we recommend improvement in the existing PIs based on best practice for information content and design.

Beyond needs and expectations: identifying the barriers and facilitators to written medicine information provision and use in Australia

PURPOSE

This study aimed to explore peoples' needs and expectations of written medicines information (WMI), and to determine the barriers and facilitators experienced or perceived in the context of WMI provision and use.

METHODS

We conducted eight focus groups with 62 participants over 6 weeks in late 2008 in New South Wales, Australia. Using a semi-structured topic schedule and examples of WMI from Australia and other English-speaking countries as a guide, we explored themes relevant to WMI, including participant experiences, attitudes, beliefs and expectations.

FINDINGS

Our findings suggest less than half had previously received WMI, with many unaware of its availability. Many, but not all, wanted WMI to supplement the spoken information they received but not to replace it, and it was predominantly used to facilitate informed choice, ascertain medicine suitability and review instructions. The current leaflets were considered technical and long, and a summary leaflet in addition to comprehensive information was favoured. Accurate side-effect information was the most important element that participants desired. The most common barriers to effective WMI use were time constraints and patient confidence, with participants citing empowerment, time and health-care professional (HCP)-patient relationships as important facilitators.

CONCLUSION

The findings provide insight and understanding of peoples needs and expectations, and clarify issues associated with use and non-use of WMI. Challenges include addressing the barriers, especially of time and HCP attitudes to drive changes to workplace practices, and learning from the facilitating factors to encourage awareness and accessibility to WMI as a tool to empower patients.

Tools used to evaluate written medicine and health information: document and user perspectives

This study aims to identify and review tools used to evaluate consumer-oriented written medicine (WMI) and health (WHI) information from a document and user perspective. Articles that met the following inclusion criteria were reviewed: studies evaluating readability, presentation, suitability, quality of WMI/WHI. A total of 152 articles were identified, of which 64 satisfied the inclusion criteria. Fifty-nine original studies used evaluation tools and 5 reviewed a specific group of tools. Sixteen detailed the development or validation of an instrument. Fifteen studies evaluated WMI and 28 evaluated WHI. Twenty-three evaluation instruments were identified. Of the seven readability tests, SMOG was predominantly used (12 of 43 studies). Eight tools measured health literacy, with REALM being the most popular instrument (7 of 43). SAM was the most commonly used presentation tool (12 of 43 studies). Many tools are available to evaluate WMI and WHI. However, the majority are researcher focused. Most evaluate readability and presentation, revealing a gap in valid and reliable tools for assessing quality of information, and those that can be used by consumers.

Providing health information to older adults

Providing information to older adults is essential for informed decision-making and good health. Because there are significant deficits in providing information verbally, health professionals must use written information as well. Most studies have focused on the content and literacy of documents. However, the legibility and formatting are critically important for older adults, who are more likely to suffer with visual impairment. Providing written information that is tested for appropriate reading level and for presentation is necessary to ensure that older adults can use the information given. There are a number of tools available that test these aspects of written information, but not one tool that is universally accepted. Further research regarding the design and presentation of written information for older adults is necessary.

Sources of drug information for patients with chronic conditions in Alexandria, Egypt

Objectives

This study sought to identify patients' perceived drug knowledge, need for more information and drug information sources, and how they varied by patient characteristics, particularly education level.

Methods

A convenience sample of 366 adult patients was interviewed when leaving 20 Egyptian pharmacies after collecting a dispensed prescription. Patients were asked about their (1) perceived knowledge of their drugs' purpose, (2) use of package inserts (PIs) to learn about side effects, contraindications and drug interactions, (3) perceived need to know more about their drugs and (4) general sources of drug information beyond healthcare providers.

Key findings

More than 30% of the patients reported that they did not know the purpose of at least one of their drugs and only read PIs selectively. Whereas 36% read about drug interactions, more reported reading about side effects (65%) and contraindications (60%) in PIs. Sixty-nine per cent of patients reported that they needed more information about their drugs. This was true for 86.8% of patients with limited education compared to 48.5% of university graduates. University graduates reported using PI topics, newspapers, internet, TV and family and friends as sources of drug information at significantly higher rates than did patients with lower levels of education.

Conclusion

There is a need for healthcare professionals to evaluate patient comprehension and needs for drug information, especially for patients with less schooling. Healthcare providers should also consider other information sources that a patient is using.

Readability of patient and health care professional targeted dietary supplement leaflets used for diabetes and chronic fatigue syndrome

OBJECTIVES

The purpose of this study was to assess readability of patient and health care professional targeted dietary supplement (DS) leaflets used for diabetes mellitus (DM) and chronic fatigue syndrome (CFS) with a novel measurement tool and Flesch-Kincaid Grade Level (FKGL).

METHODS

Patient and professional leaflets for DS used to treat DM and CFS from the Natural Medicines Comprehensive Database (NMCD) and Natural Standard (NS) databases were evaluated. Leaflets were analyzed using FKGL and the author-developed health information readability analyzer (HIReA). HIReA integrates lexical, semantic, syntactic, cohesion, and style features and yields values of -1 (very hard) to 1 (very easy).

RESULTS

Patient-targeted leaflets substantially exceeded the consensus readability level (6th grade) as assessed by both FKGL (grade 13.0767) and HIReA (-0.2360). Professional leaflets were similarly more difficult to read as scored by HIReA (-0.7065) and FKGL (grade 14.7429). Most and least difficult-to-read sections in patient leaflets (NS/NMCD) were Related Terms (-0.8863)/Other Names (-0.8146), and Safety Concerns (0.0821)/Scientific Evidence (0.0629), respectively. Overall, leaflets in NS (-0.5721) were more difficult to read than those in NMCD (-0.3704). These differences appeared to be less pronounced when FKGL was used to assess the readability, indicating its lack of preciseness.

CONCLUSIONS

Readability for patient targeted DS leaflets is far more difficult than recommended levels. HIReA is a more precise method to measure readability than FKGL. The disparity between targeted levels of readability and measured levels may contribute to a lack of understanding by patients, with a resulting negative impact on adherence and outcomes.

Consumer use of the internet for medicines information

Objective

To explore consumer opinion of the internet as a source of medicines information, the reasons consumers use this information, and the impact of this information on their use of medicines.

Method

Focus groups (n=6) were conducted in metropolitan Sydney, Australia during March to May 2003 with consumers (n=46) who had used the internet for medicines information.

Key findings

Although participants expressed some concerns about the quality of internet-based medicines information (IBMI), the convenience of access to this information outweighed these reservations. Attitudes were thus positive overall. Participants used IBMI when preparing for doctors' visits, for second opinions and additional information, for information on current issues, when deciding whether to use a medicine, for comparative information on brands and generics, and when written information was not supplied by health professionals. Most participants felt empowered by the information they found and used it to play a more active role in decision making about their therapy.

Conclusion

This study describes various issues associated with consumer use of IBMI and highlights the possible role of pharmacists to support their patients' efforts to access and interpret medicines information.

Written Medicine Information from English-Speaking Countries—How Does It Compare?

Background:

There has been an increasing drive from consumers for more information to be available about their medicines. However, the layout and presentation of such written information is variable, and the poor format and design discourages people from reading the documents.

Objective:

To identify, collate, and evaluate different formats of written medicine information (WMI).

Methods:

Three researchers evaluated 157 samples of WMI for 10 prescription and 3 over-the-counter medicines from 6 English-speaking countries compared with the United States Keystone Consensus Criterion 8 (USKCC8) and the Ten Key Principles (TKP) of Consumer Medicine Information. Readability was measured using Flesch-Kincaid Grade Level (FKGL) and Fog tests. Compliance (%) with the criteria was computed and examined using the median test.

Results:

Overall median compliance with USKCC8 was 70%, and 74% to TKP. New Zealand leaflets achieved the highest compliance with USKCC8 (83%, Interquartile range (IQR) 70–89%), with US leaflets the lowest (55%. IQR 45–70%). Australian and New Zealand leaflets showed the highest compliance with TKP (90%, IQR 80–100% and 87–97%, respectively), while UK leaflets demonstrated the lowest (60%, IQR 52–71%). Overall median reading grades for the leaflets were 10 (Flesch-Kincaid Grade Level) and 11 (Fog).

Conclusions:

Compliance with USKCC8 and TKP varied greatly between countries, with readability grades exceeding the recommended range. International examples of WMI show wide variation in compliance with guidelines on recommended format and presentation. These examples of WMI require high literacy to read. Future WMI development should use more recommended formats and increase comprehensibility.

Written information about individual medicines for consumers

BACKGROUND

Medicines are the most common intervention in most health services. As with all treatments, those taking medicines need sufficient information: to enable them to take and use the medicines effectively, to understand the potential harms and benefits, and to allow them to make an informed decision about taking them. Written medicines information, such as a leaflet or provided via the Internet, is an intervention that may meet these purposes.

OBJECTIVES

To assess the effects of providing written information about individual medicines on relevant patient outcomes (knowledge, attitudes, behaviours and health outcomes) in relation to prescribed and over-the-counter medicines.

SEARCH STRATEGY

We searched MEDLINE, EMBASE, CINAHL, The Cochrane Library, PsycINFO and other databases to March 2007. We handsearched five journals' tables of contents, and the reference lists of included studies, and contacted experts in the field.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of medicine users, comparing written medicines information with no written medicines information; or trials that compared two or more styles of written medicines information. We only included trials that measured a knowledge, attitudinal or behavioural outcome. There were no language restrictions.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data relating to the interventions, methods of the trials, and outcome measures; and reconciled differences by discussion. Heterogeneity of interventions and outcomes measured meant that data synthesis was not possible. The results are presented in narrative and tabular format.

MAIN RESULTS

We included 25 RCTs involving 4788 participants. Six of twelve trials showed that written information significantly improved knowledge about a medicine, compared with no written information. The inability to combine results means we cannot conclude whether written information was effective for increasing knowledge. The results for attitudinal and behavioural outcomes were mixed. No studies showed an adverse effect of medicines information.

AUTHORS' CONCLUSIONS

The combined evidence was not strong enough to say whether written medicines information is effective in changing knowledge, attitudes and behaviours related to medicine taking. There is some evidence that written information can improve knowledge. The trials were generally of poor quality, which reduces confidence in the results. Trials examining the effects of written information need to be better designed and use consistent and validated outcome measures. Trials should evaluate internet-based medicines information. It is imperative that written medicines information be based on best practice for its information design and content, which could improve its effectiveness in helping people to use medicines appropriately.

Key Principles to Guide Development of Consumer Medicine Information—Content Analysis of Information Design Texts

Background:

Effective written consumer medicines information is essential to support safe and effective medicine taking, but the wording and layout of currently provided materials do not meet patients' needs.

Objective:

To identify principles from the wider discipline of information design for use by health professionals when developing or assessing written drug information for patients.

Methods:

Six experts in information design nominated texts on best practice in information design applicable to consumer medicines information. A content analysis identified key principles that were tabulated to bring out key themes.

Results:

Six texts that met the Inclusion criteria, were Identified, and content analysis indentified 4 themes: words, type, lines, and layout. Within these main themes, there were 24 subthemes. Selected principles relating to these subthemes were: use short familiar words, short sentences, and short headings that stand out from the text; use a conversational tone of voice, addressing the reader as “you”; use a large type size while retaining sufficient white space; use bullet points to organize lists; use unjustified text (ragged right) and bold, lower-case text for emphasis. Pictures or graphics do not necessarily improve a document.

Conclusions:

Applying the good information design principles identified to written consumer medicines information could support health professionals when developing and assessing drug information for patients.

Do Medication Samples Jeopardize Patient Safety?

BACKGROUND

Medication samples are commonly dispensed by prescribers. Written consumer medication information (CMI) provided with sample packaging is an important source of patient information. Although one-third of Americans have health literacy deficiencies, previous studies have found that CMI is often too complex for many patients to understand. This may prevent patients from using these medications appropriately.

OBJECTIVE

To evaluate readability and formatting characteristics of CMI included with nonsolid (ie, topical cream/lotion, inhalation, transdermal) drug samples.

METHODS

We collected a convenience sample of nonsolid dosage sample medications (N = 55) from several different private and university-affiliated primary care and specialty physician practices at a large academic medical center in the southeastern US. We noted whether CMI was present and, if it was, we assessed it for instruction presentation, reading level, text size, format/layout, and comprehensibility.

RESULTS

Most (43 of 55) products included CMI, either as a separate leaflet or directly on the packaging. Reading level of CMI leaflets ranged from the 6th- to 14th-grade level, with just 4 (16.0%) written at the recommended 6th-grade level. Text font point size was 9.48 ± 2.14 (mean ± SD; range 5–12). Text printed directly on sample packaging averaged 6.61 point ± 2.62 (4–11) font size. Ninety-two percent of CMI leaflets included a combination of text and pictures; only 11.1% of CMI printed directly on the packaging used pictorial aids.

CONCLUSIONS

Most CMI accompanying nonsolid medication samples is written at a reading level that exceeds that of many consumers and does not meet recommended standards for readability and comprehensibility of patient education material.

Comparative analysis of patient package inserts of local and imported anti-infective agents in palestine

BACKGROUND AND OBJECTIVE

The patient package insert is an important source of drug information. The aim of this study was to evaluate and compare the PPI of the anti-infective agents manufactured in Palestine with the imported equivalents.

METHOD

The selection criteria generated 15 different anti-infective agents available as 36 locally manufactured products and 15 imported equivalents. The design of the patient package insert was evaluated in terms of the number of words used in eight main headings and the presence or absence of certain information regarding nine statements.

RESULTS

Inserts of locally manufactured products have significantly fewer words than those of imported products with respect to warnings, dosage and administration, and side effects. The most significant difference was found in the warnings. Moreover, differences were found between inserts of local and imported products in terms of the presence of the nine informative statements. Locally manufactured products did not mention inactive ingredients, clinical pharmacology or date of last revision, but all of them provided information on the use of the drug during pregnancy and lactation and on the duration of therapy. However, in general they provided less information than the imported equivalents.

CONCLUSION

Palestinian authorities and local manufacturers should implement appropriate measures to regulate the quality and quantity of information in the patient package insert of locally produced anti-infective agents. PPI improvement will better direct health practices to the benefit of the patients.

Scope, completeness, and accuracy of drug information in Wikipedia

BACKGROUND

With the advent of Web 2.0 technologies, user-edited online resources such as Wikipedia are increasingly tapped for information. However, there is little research on the quality of health information found in Wikipedia.

OBJECTIVE

To compare the scope, completeness, and accuracy of drug information in Wikipedia with that of a free, online, traditionally edited database (Medscape Drug Reference [MDR]).

METHODS

Wikipedia and MDR were assessed on 8 categories of drug information. Questions were constructed and answers were verified with authoritative resources. Wikipedia and MDR were evaluated according to scope (breadth of coverage) and completeness. Accuracy was tracked by factual errors and errors of omission. Descriptive statistics were used to summarize the components. Fisher's exact test was used to compare scope and paired Student's t-test was used to compare current results in Wikipedia with entries 90 days prior to the current access.

RESULTS

Wikipedia was able to answer significantly fewer drug information questions (40.0%) compared with MDR (82.5%; p < 0.001). Wikipedia performed poorly regarding information on dosing, with a score of 0% versus the MDR score of 90.0%. Answers found in Wikipedia were 76.0% complete, while MDR provided answers that were 95.5% complete; overall, Wikipedia answers were less complete than those in Medscape (p < 0.001). No factual errors were found in Wikipedia, whereas 4 answers in Medscape conflicted with the answer key; errors of omission were higher in Wikipedia (n = 48) than in MDR (n = 14). There was a marked improvement in Wikipedia over time, as current entries were superior to those 90 days prior (p = 0.024).

CONCLUSIONS

Wikipedia has a more narrow scope, is less complete, and has more errors of omission than the comparator database. Wikipedia may be a useful point of engagement for consumers, but is not authoritative and should only be a supplemental source of drug information.

The role and value of written information for patients about individual medicines: a systematic review

OBJECTIVE

To review research on the role and value of written medicines information for patients from the perspective of patients and health professionals.

CONTEXT

Providing written information to patients about their medicines is acknowledged as a priority but there is poor understanding of how best to meet patients' needs.

METHOD

A sensitive search strategy was developed to maximize the identification of relevant studies. We used a data extraction form designed to appraise qualitative research. Findings were synthesized into a narrative account.

MAIN RESULTS

There were three broad categories of study: those which related to policy initiatives; those where the aim was to increase compliance; and those concerned with using information to support decision-making ('informed patient' studies). While the policy initiative and compliance studies reported that, mostly, patients were positive about written information, the 'informed patient' studies showed a more complex picture. Patients valued medicines information tailored to their condition. They did not want it to be a substitute for spoken information from their doctor. Not everyone wanted written information but those who did wanted sufficient detail to meet their need. Need varied over time and between patients. The small number of studies relating to health professionals showed widespread ambivalence towards using written information. Some thought it should be brief and simple, only partially disclose side-effects and saw its main role as being to increase compliance.

CONCLUSION

The different perspectives of patients and health professionals, and the diverse and changing information needs of patients pose a challenge to providers of written medicines information.

Impact of Vietnamese written and verbal medicine information on Vietnamese-speaking Australians' knowledge and satisfaction

AIMS

To develop three Vietnamese medicine information leaflets and to evaluate their impact in combination with verbal counselling (in Vietnamese) on consumers' medicine knowledge and satisfaction with the written information received.

METHODS

Leaflets in Vietnamese were developed for three drug classes: biguanides, calcium channel blockers and HMG-CoA reductase inhibitors. A two-group (comparison and intervention), randomized, repeated measures design was used. The comparison group (n = 51) received routine verbal counselling in English. The intervention group (n = 44) received verbal and written information in Vietnamese. Australian Vietnamese-speaking consumers were recruited. Data on consumer knowledge and satisfaction were collected from both groups at three time points: baseline (prior to receiving leaflets and verbal counselling), at 1-2 weeks (first postintervention) and 8 weeks after receiving the information.

RESULTS

All intervention group respondents were satisfied with the information. Mean medicine knowledge and satisfaction scores increased with time in the intervention group, and were significantly higher than in the comparison group (knowledge, F = 18.5, d.f. = 2, P < 0.0001; satisfaction, F = 19.8, d.f. = 2, P < 0.0001). The increases observed in the intervention group's mean knowledge and satisfaction scores at first postintervention were significantly higher compared with baseline for all drug classes.

CONCLUSIONS

Delivery of written and verbal medicine information in Vietnamese resulted in an increase in consumers' medicine knowledge and satisfaction with written information. This study highlights the importance of providing information in languages other than English and in consumers' native tongue to aid in the quality use of medicines.
