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

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.

Do Patients Use a Headline Section in a Leaflet to Find Key Information About Their Medicines? Findings From a User-Test Study

BACKGROUND

In the European Union (EU), all medicines are mandated to be provided with a patient information leaflet (PIL). Many patients express concerns about the length and complexity of some PILs, and this can be a disincentive for patients to read the PILS. In order to address this, the UK's regulatory body (Medicine and Healthcare products Regulatory Agency [MHRA]) suggested leaflets might include a headline section-information presented prominently at the beginning of a leaflet that summarizes key safety messages about a drug.

OBJECTIVE

To explore the extent to which readers used a headline section in a PIL, using a form of diagnostic testing called user-testing, which examines how readers find and understand key information.

METHODS

The study used a cross-sectional design to user-test a PIL with a headline section in a target sample of 20 participants. Participants were provided with an exemplar PIL, and the performance of the PIL was evaluated by a questionnaire and semistructured interview.

RESULTS

The results showed that a headline section was used just over one-third of the time (39%); 90% of participants used the headline section to find information when they initially began the user-test. The qualitative findings suggested that the participants valued the presence of the headline section.

CONCLUSION

The research suggests there does not appear to be any negative impact from including a headline section in a PIL, and it is a technique that is highly valued by the consumers of medicines information.

Knowledge and perceptions of the risks of non-steroidal anti-inflammatory drugs among orthopaedic patients in Thailand

Background There is a high incidence of adverse effects from non-steroidal antiinflammatory drugs (NSAIDs) in Thailand, but patients' perceptions and knowledge of NSAID risks is unknown. Objective This study aims to assess patients' perceptions and knowledge of NSAID risks and factors affecting them. Setting University hospital in North-East of Thailand. Method A Cross-sectional study conducted over 4 months, using a self-administered questionnaire. Patients prescribed NSAIDs for at least one month duration from orthopaedic clinic were recruited using systematic random sampling. Main outcome measure Patients' perceptions on NSAID risks, knowledge on risk factors, and their associated factors. Results A total of 474 questionnaires were assessed. Overall perceptions of risks was low (scoring below five on a 0-10 visual analogue scale), with risks associated with the renal system scoring highest. Perceived risk of gastrointestinal problems differed between patients using non-selective and selective NSAIDs (3.47 ± 2.75 vs 2.06 ± 2.98; P < 0.001). Receiving side effect information from a health professional was associated with higher risk perception. Most patients (80 %) identified high doses, renal disease and gastrointestinal ulcer increased risks of NSAIDs, but fewer than half recognized that use in the elderly, multiple NSAID use, drinking, hypertension and cardiovascular disease also increased risk of adverse events. Having underlying diseases and receiving side effect information were associated with 1.6-2.0 fold increased knowledge of NSAID risks. Conclusion Perceptions and knowledge concerning NSAID risks was generally low in Thai patients, but higher in those who had received side effect information. Risk-related information should be widely provided, especially in high-risk patients.

Experiences of and attitudes towards receiving information about non-steroidal anti-inflammatory drugs: a cross-sectional survey of patients in Thailand

OBJECTIVE

To determine sources of information about NSAIDs used by out-patients, factors related to receipt of information and patient attitudes towards receiving safety information.

RESEARCH DESIGN AND METHODS

Cross-sectional survey, using self-completed questionnaires distributed directly to 500 outpatients prescribed any NSAIDs from an orthopaedic clinic in Thailand, over a 4-month period.

RESULTS

There were 548 patients approached and 474 completed questionnaires returned (94.8%). The most frequent aspects of medicines information that were provided related to administration (97.2%), mostly provided by pharmacists, and indication (85.8%), mostly provided by physicians. Information on identifying, monitoring and managing adverse effects was received by fewer than 50% of patients. Safety information was received significantly more frequently by younger patients (P<0.01), those using non-selective COX-2 inhibitors (P<0.001), intermittent NSAIDs (P<0.05) and fewer concomitant medicines (P<0.05). Only 14.1% patients used additional information sources. Attitudes towards receiving medicines safety information were positive. Most patients agreed they should know about ADRs (98.1%) and receive information leaflets with first prescription (96.8%).

CONCLUSIONS

Patients received medicines information mostly from healthcare professionals, but safety information was limited. Type of NSAIDs, regularity of NSAID use and age affected receipt of safety information about NSAIDs. Provision of more medicine information is needed, particularly written documents.

Experiences relating to adverse drug reactions in the community: a cross-sectional survey among patients and the general public in Thailand

OBJECTIVE

To determine the frequency and characteristics of adverse drug reactions (ADRs), experiences of receiving and desire for information about medicines, and attitudes toward ADR knowledge and reporting among the community-dwelling Thai population.

METHODS

A cross-sectional self-administered survey conducted during October 2013 to December 2014 by convenience sampling. The study was conducted in three settings in the second-largest city, North-eastern Thailand: primary care units, community pharmacies and public areas.

RESULTS

Of 2400 respondents, 414 (17.3%) reported experiencing an ADR; two-thirds of which involved mild symptoms (66.7%) and 55.6% occurred within the last year. Self-reported ADR knowledge was low (4.1 ± 2.5 on a scale of 0 to 10). Pharmacists and physicians were the most common sources of information about medicines, but only 28.5% had received information about ADRs. Over 40% wanted information about ADRs and drug interactions, with healthcare professionals and information leaflets being desirable sources. The majority of individuals had positive views towards both receiving information and reporting their ADR experiences.

CONCLUSIONS

To enable the Thai public to report their experiences of ADRs more effectively, they require more medicines information. Information leaflets should be more widely available, while healthcare professionals should provide more detailed information of ADRs.

Preconception-related needs of reproductive-aged women

OBJECTIVE

to assess women׳s interest in preconception care, their organisational preferences, and their preconception-related information and support needs.

DESIGN

cross-sectional study design.

SETTING

participants were recruited online through social media and discussion forums for issues relating to (in)fertility, pregnancy and parenting, and at the Women׳s Clinic of Ghent University Hospital.

PARTICIPANTS

242 reproductive-aged women with a desire to have (more) children.

FINDINGS

the majority of women (75%) wanted to receive preconception care in the future. Gynaecologists (93%) were the preferred source of preconception care, followed by midwives (73%) and general practitioners (63%). Most women wanted information about lifestyle, environmental exposures, working conditions and medical issues. Information needs were higher among women with (history of) mental illness [odds ratio (OR) 3.50, 95% confidence interval (CI) 1.08-11.36], (history of) eye and otolaryngological problems (OR 2.22, 95% CI 0.95-5.21) and overweight (OR 2.22, 95% CI 1.01-4.93). A few women indicated that they needed preconception-related support. Overweight women reported greater need for lifestyle-related support compared with women of healthy weight (p=0.001).

KEY CONCLUSIONS

reproductive-aged women are interested in preconception care, and would prefer to receive this care directly from a professional caregiver. Most women had high preconception-related information needs and lower support needs.

IMPLICATIONS FOR PRACTICE

although women reported that they would prefer to receive preconception care from gynaecologists, the results indicate that midwives can also play an important role in the provision of preconception care. They would need further training to improve their knowledge, skills and awareness regarding preconception care.

Understanding the medicines information-seeking behaviour and information needs of South African long-term patients with limited literacy skills

BACKGROUND

Although much health information-seeking behaviour (HISB) research has been reported in patients with good literacy skills, little is known about HISB in patients with limited literacy skills served by under-resourced health-care systems.

OBJECTIVE

To investigate medicine information-seeking behaviour and information needs in patients with limited literacy.

METHODS

Using a question guide, four focus group discussions (FGDs) were conducted to explore themes related to information needs, information-seeking practices and awareness of and ability to utilize information sources. Twenty-two isiXhosa-speaking long-term patients with limited formal education were recruited from a primary health-care clinic in South Africa. Discussions were audio-recorded and transcribed verbatim. NVivo(®) was used for initial coding of transcripts. Codes were analysed, and potential themes and subthemes in the entire data set were identified and refined.

FINDINGS

The results of this study reflect a passive, disempowered patient. Poor awareness of information sources, lack of health-related knowledge and stigma contributed to a lack of information-seeking practice, thus potentially adversely influencing patient-provider interactions. Patients neither asked questions nor were encouraged to ask questions. All expressed an unmet need for information and a desire for receiving the illustrated written medicines-related information displayed in the FGDs. The main sources of information were health-care professionals, followed by family and friends.

CONCLUSION

The significant level of patient disempowerment and passivity reported amongst patients underpinned their inability to actively seek information. Neither sources of information nor types of appropriate medicines information could be identified. Unmet information needs and a desire for information were reported.

Impact of Contraceptive Education on Contraceptive Knowledge and Decision Making: A Systematic Review

CONTEXT

Educational interventions can help increase knowledge of available contraceptive methods, enabling individuals to make informed decisions and use contraception more effectively. This systematic review evaluated contraceptive education interventions to guide national recommendations on quality family planning services.

EVIDENCE ACQUISITION

Three databases (CINAHL, PubMed, and PsycINFO) were searched from 1985 through 2012 for peer-reviewed articles on educational interventions, with supplemental searches conducted through 2015. Primary outcomes were knowledge, participation in and comfort with decision making, and attitudes toward contraception. Secondary outcomes included contraceptive use behaviors and unintended pregnancy.

EVIDENCE SYNTHESIS

Database searches in 2011 identified 5,830 articles; 17 met inclusion criteria and were abstracted into evidence tables. Searches in 2012 and 2015 identified four additional studies. Studies used a wide range of tools (decision aids, written materials, audio/videotapes, and interactive games), with and without input from a healthcare provider or educator. Of 15 studies that examined the impact of educational interventions on knowledge, 14 found significant improvement using a range of tools, with and without input from a healthcare provider or educator. Fewer studies evaluated outcomes related to decision making, attitudes toward contraception, contraceptive use behaviors, or unintended pregnancy.

CONCLUSIONS

Results from this systematic review are consistent with evidence from the broader healthcare field suggesting that a range of educational interventions can increase knowledge. Future studies should assess what aspects of educational interventions are most effective, the extent to which it is necessary to include a healthcare provider or educator, and the extent to which educational interventions can impact behaviors.

Patient empowerment in the management of chronic myeloid leukemia

Patient empowerment is a patient-centered approach to care in which healthcare providers nurture patients' innate abilities to self-manage and incorporate patient goals for therapy into the overall management plan. Standard care of chronic myeloid leukemia (CML) requires lifelong medication with oral therapy and regular follow-up. The success of CML treatment, therefore, depends on a high degree of patient involvement and motivation, as well as strong collaboration between patients and healthcare providers. Oncology nurses can support patients with CML from the time of diagnosis to the end of treatment to ensure they maintain high levels of involvement in their care. At the author's center, patients who most actively collaborate with their physicians in treatment decisions take personal responsibility for the quality of their care and show good adherence to treatment. In the current article, the author discusses the potential effect of patient response to cancer diagnosis on clinical outlook and describes strategies in place at the cancer center to ensure that patients diagnosed with CML have the best chance at keeping their cancer under control.

Patients' general satisfaction with telephone counseling by pharmacists and effects on satisfaction with information and beliefs about medicines: Results from a cluster randomized trial

OBJECTIVE

Assess effects of pharmacists' counseling by telephone on patients' satisfaction with counseling, satisfaction with information and beliefs about medicines for newly prescribed medicines.

METHODS

A cluster randomized trial in Dutch community pharmacies. Patients ≥18 years were included when starting with antidepressants, bisphosphonates, RAS-inhibitors or statins. The intervention comprised counseling by telephone to address barriers to adherent behavior. It was supported by an interview protocol. Controls received usual care. Outcomes were effects on beliefs about medication, satisfaction with information and counseling. Data was collected with a questionnaire.

RESULTS

Responses of 211 patients in nine pharmacies were analyzed. More intervention arm patients were satisfied with counseling (adj. OR 2.2 (95% CI 1.3, 3.6)). Patients with counseling were significantly more satisfied with information on 4 items, had less concerns and less frequently had a 'skeptical' attitude towards medication (adj. OR 0.5 (0.3-0.9)). Effects on most outcomes were more pronounced in men than in women.

CONCLUSIONS

Telephone counseling by pharmacists improved satisfaction with counseling and satisfaction with information on some items. It had a small effect on beliefs about medicines.

PRACTICE IMPLICATIONS

Pharmacists can use counseling by telephone, but more research is needed to find out which patients benefit most.

Developing visual images for communicating information aboutantiretroviral side effects to a low-literate population

The side effects of antiretroviral (ARV) therapy are linked to altered quality of life and adherence. Poor adherence has also been associated with low health-literacy skills, with an uninformed patient more likely to make ARV-related decisions that compromise the efficacy of the treatment. Low literacy skills disempower patients in interactions with healthcare providers and preclude the use of existing written patient information materials, which are generally written at a high reading level. Visual images or pictograms used as a counselling tool or included in patient information leaflets have been shown to improve patients' knowledge, particularly in low-literate groups. The objective of this study was to design visuals or pictograms illustrating various ARV side effects and to evaluate them in a low-literate South African Xhosa population. Core images were generated either from a design workshop or from posed photos or images from textbooks. The research team worked closely with a graphic artist. Initial versions of the images were discussed and assessed in group discussions, and then modified and eventually evaluated quantitatively in individual interviews with 40 participants who each had a maximum of 10 years of schooling. The familiarity of the human body, its facial expressions, postures and actions contextualised the information and contributed to the participants' understanding. Visuals that were simple, had a clear central focus and reflected familiar body experiences (e.g. vomiting) were highly successful. The introduction of abstract elements (e.g. fever) and metaphorical images (e.g. nightmares) presented problems for interpretation, particularly to those with the lowest educational levels. We recommend that such visual images should be designed in collaboration with the target population and a graphic artist, taking cognisance of the audience's literacy skills and culture, and should employ a multistage iterative process of modification and evaluation.

Disclosing discourses: biomedical and hospitality discourses in patient education materials

Patient education materials have the potential to strengthen the health literacy of patients. Previous studies indicate that readability and suitability may be improved. The aim of this study was to explore and analyze discourses inherent in patient education materials since analysis of discourses could illuminate values and norms inherent in them. Clinics in Sweden that provided colorectal cancer surgery allowed access to written information and 'welcome letters' sent to patients. The material was analysed by means of discourse analysis, embedded in Derrida's approach of deconstruction. The analysis revealed a biomedical discourse and a hospitality discourse. In the biomedical discourse, the subject position of the personnel was interpreted as the messenger of medical information while that of the patients as the carrier of diagnoses and recipients of biomedical information. In the hospitality discourse, the subject position of the personnel was interpreted as hosts who invite and welcome the patients as guests. The study highlights the need to eliminate paternalism and fosters a critical reflective stance among professionals regarding power and paternalism inherent in health care communication.

The role of patients in pressure injury prevention: a survey of acute care patients

Background

Pressure injury prevention (PIP) is an important area of patient safety. Encouraging patient participation in care is a growing trend in healthcare as it can increase adherence to treatment plans and improve outcomes. Patients in acute care settings may be able to take on an active role in PIP. However, there is limited information on patients’ views of their perceived role in PIP. The aims of our study were to survey hospitalised patients’ views on a) their perceived roles in PIP and, b) factors that enable or inhibit patient participation in PIP strategies.

Methods

Eligible participants were 18 years of age or older, from a neurology or orthopaedic ward and had been admitted to hospital at least 24 hours prior to enrolment in the study. A questionnaire comprising of fixed and open-ended responses was administered by researchers to participants. Numerical data was analysed descriptively and free-text comments were content-analysed and grouped into themes.

Results

The mean age of participants (n = 51) was 65 years (sd = 16.6); over half were female and three quarters were orthopaedic surgical patients. Eighty-six per cent of participants understood the concept of pressure injury and 80% agreed that patients have a role in PIP. Participants nominated the following PIP strategies that could be undertaken by patients: Keep skin healthy; Listen to your body and Looking after the inside. Strategies required for patient participation in PIP were represented by three themes: Manage pain and discomfort; Work together; Ongoing PI education.

Conclusion

To ensure successful participation in PIP, patients require education throughout admission, management of pain and discomfort and a supportive and collaborative relationship with health care staff. Health professionals should identify patient ability and motivation to prevent pressure injury (PI), work in partnership with patients to adhere to PIP, and ensure that PIP actions are facilitated with appropriate pain relief.

Patients' antibiotic knowledge: a trial assessing the impact of verbal education

OBJECTIVES

The purpose of this study was to assess the effectiveness of involving community pharmacy staff in patient education about antibiotic resistance, thus improving antibiotic knowledge.

METHODS

Thirty-four patients presenting a valid antibiotic script for dispensing at three community pharmacies in regional New South Wales, Australia were randomly allocated by ballot draw to an intervention group or control group. Those in the intervention group were provided with verbal education based on an Australian National Prescribing Service patient leaflet regarding antibiotics.

KEY FINDINGS

This paper presents pilot data indicating that there was a significant increase in antibiotic knowledge determined approximately 1 month after receiving verbal antibiotic education (33.3 ± 40.8) as compared with patients not receiving verbal antibiotic education (-5.1 ± 23.0), t (18.9) = 2.957, P = 0.008.

CONCLUSIONS

This study has shown that verbal education, provided within a community pharmacy, regarding antibiotics improved patients' knowledge about antibiotics and provides evidence for the critical role of pharmacy staff in patient education.

How useful are medication patient information leaflets to older adults? A content, readability and layout analysis

BACKGROUND

Patient information leaflets (PILs) are the most important information source for older patients to effectively manage their drug therapy.

OBJECTIVE

The objective of this study is to evaluate the appropriateness of current available PILs for use by older adults.

METHODS

The content of the PILs were assessed by checking the availability of information relevant to older patients including pharmacokinetics, safety and dose instructions. The layout of the PILs was evaluated using criteria derived from the relevant regulatory guidelines on the design of PILs. The Gunning Fog Index was used to determine the readability of the PILs to older adults.

RESULTS

Total of 48 PILs were analysed involving 25 drug substances for the treatment of cardiovascular disease and type 2 diabetes. One out of the 48 PILs contained information on pharmacokinetic changes in older patients and only 15 % of the PILs specified the age of the older person. Thirty-one percent of the PILs provided nonspecific warnings to the older population, while only 15 % included specific side effects that could occur in the older generation. Text font sizes of the PILs were generally too small for older adults to read, with only 9 % of the PILs used type size 12 or over. The readability of 63 % of the PILs had a score above 12, which is considered difficult for older people to understand.

CONCLUSION

Currently available medication PILs are inappropriate for use by older adults to manage their medications effectively, which could adversely affect patient safety and adherence to drug therapy.

Exploring consumer opinions on the presentation of side-effects information in Australian Consumer Medicine Information leaflets

Background

Consumer Medicine Information (CMI) is a brand‐specific and standardized source of written medicine information available in Australia for all prescription medicines. Side‐effect information is poorly presented in CMI and may not adequately address consumer information needs.

Objective

To explore consumer opinions on (i) the presentation of side‐effect information in existing Australian CMI leaflets and alternative study‐designed CMIs and (ii) side‐effect risk information and its impact on treatment decision making.

Design

Fuzzy trace, affect heuristic, frequency hypothesis and cognitive‐experiential theories were applied when revising existing CMI side‐effects sections. Together with good information design, functional linguistics and medicine information expertise, alternative ramipril and clopidogrel CMI versions were proposed. Focus groups were then conducted to address the study objectives.

Participants and setting

Three focus groups (n = 18) were conducted in Sydney, Australia. Mean consumer age was 58 years (range 50–65 years), with equal number of males and females.

Results

All consumers preferred the alternative CMIs developed as part of the study, with unequivocal preference for the side‐effects presented in a simple tabular format, as it allowed quick and easy access to information. Consumer misunderstandings reflected literacy and numeracy issues inherent in consumer risk appraisal. Many preferred no numerical information and a large proportion preferred natural frequencies.

Conclusions

One single method of risk presentation in CMI is unable to cater for all consumers. Consumer misunderstandings are indicative of possible health literacy and numeracy factors that influence consumer risk appraisal, which should be explored further.

Pharmacist, general practitioner and consumer use of written medicine information in Australia: are they on the same page?

BACKGROUND

Providing written medicine information to consumers enables them to make informed decisions about their medicines, playing an important role in educating and improving health literacy. In Australia, standardized written medicine information called Consumer Medicine Information (CMI) is available for medicines as package inserts, computer prints, or leaflets. Consumers want and read CMI, but may not always ask for it. General practitioners (GPs) and pharmacists are an important source of written medicine information, yet may not always provide CMI in their practice.

OBJECTIVE

To examine and compare the awareness, use and provision of CMI by consumers, pharmacists and general practitioners (GPs).

METHODS

Based on previous studies, structured questionnaires were developed and administered to a national sample of consumers (phone survey); community pharmacists and GPs (postal surveys) about utilization of CMI. Descriptive, comparative and logistic regression analyses were conducted.

RESULTS

The respondents comprised of 349 pharmacists, 181 GPs and 1000 consumers. Two-thirds of consumers, nearly all (99%) pharmacists and 90% of GPs were aware of CMI. About 88% of consumers reported receiving CMI as a package insert, however most pharmacists (99%) and GPs (56%) reported providing computer-generated CMI. GPs' and pharmacists' main reason for providing CMI was on patient request. Reasons for not providing were predominantly because consumers were already taking the medicine, concerns regarding difficulty understanding the information, or potential non-adherence. Of the 691 consumers reportedly reading CMI, 35% indicated concerns after reading. Factors associated with reading included gender, type of CMI received and frequency of provision.

CONCLUSION

Consumers want and read information about their medicines, especially when received from their GP or pharmacist. Healthcare professionals report usually discussing CMI when providing it to patients, although continued improvements in dissemination rates are desirable. Regular use of CMI remains a challenge, and ongoing strategies to promote CMI use are necessary to improve uptake of CMI in Australia.

Evidence-based health information from the users' perspective--a qualitative analysis

BACKGROUND

Evidence-based information is a precondition for informed decision-making and participation in health. There are several recommendations and definitions available on the generation and assessment of so called evidence-based health information for patients and consumers (EBHI). They stress the importance of objectively informing people about benefits and harms and any uncertainties in health-related procedures. There are also studies on the comprehensibility, relevance and user-friendliness of these informational materials. But to date there has been little research on the perceptions and cognitive reactions of users or lay people towards EBHI. The aim of our study is to define the spectrum of consumers' reaction patterns to written EBHI in order to gain a deeper understanding of their comprehension and assumptions, as well as their informational needs and expectations.

METHODS

This study is based on an external user evaluation of EBHI produced by the German Institute for Quality and Efficiency in Health Care (IQWiG), commissioned by the IQWiG. The EBHI were examined within guided group discussions, carried out with lay people. The test readers' first impressions and their appraisal of the informational content, presentation, structure, comprehensibility and effect were gathered. Then a qualitative text analysis of 25 discussion transcripts involving 94 test readers was performed.

RESULTS

Based on the qualitative text analysis a framework for reaction patterns was developed, comprising eight main categories: (i) interest, (ii) satisfaction, (iii) reassurance and trust, (iv) activation, (v) disinterest, (vi) dissatisfaction and disappointment, (vii) anxiety and worry, (viii) doubt.

CONCLUSIONS

Many lay people are unfamiliar with core characteristics of this special information type. Two particularly critical issues are the description of insufficient evidence and the attendant absence of clear-cut recommendations. Further research is needed to examine strategies to explain the specific character of EBHI so as to minimize unintended or adverse reaction patterns. The presented framework describes the spectrum of users' reaction patterns to EBHI. It may support existing best practice models for editing EBHI.

Communicating Numerical Risk: Human Factors That Aid Understanding in Health Care

In this chapter, we review evidence from the human factors literature that verbal and visual formats can help increase the understanding of numerical risk information in health care. These visual representations of risk are grounded in empirically supported theory. As background, we first review research showing that people often have difficulty understanding numerical risks and benefits in health information. In particular, we discuss how understanding the meanings of numbers results in healthier decisions. Then, we discuss the processes that determine how communication of numerical risks can enhance (or degrade) health judgments and decisions. Specifically, we examine two different approaches to risk communication: a traditional approach and fuzzy-trace theory. Applying research on the complications of understanding and communicating risks, we then highlight how different visual representations are best suited to communicating different risk messages (i.e., their gist). In particular, we review verbal and visual messages that highlight gist representations that can better communicate health information and improve informed decision making. This discussion is informed by human factors theories and methods, which involve the study of how to maximize the interaction between humans and the tools they use. Finally, we present implications and recommendations for future research on human factors in health care.

Translating evidence for low back pain management into a consumer-focussed resource for use in community pharmacies: a cluster-randomised controlled trial

Background

This cluster-randomised controlled trial determined the effectiveness of an evidence-based, pamphlet intervention in improving low back pain (LBP)-related beliefs among pharmacy consumers.

Methods

Thirty five community pharmacies were randomised to three groups: pamphlet+education intervention [n = 11]; pamphlet only intervention [n = 11]; control: usual care [n = 13]. Eligibility requirements for clusters included: community-based pharmacies and proprietor participation consent. Pharmacy consumers (N = 317) aged 18–65 years currently experiencing LBP participated. Intervention group allocation depended on the pharmacy attended. Individual-level outcomes were measured at pre-intervention (T0), at two (T1) and eight (T2) weeks post-intervention and included beliefs about LBP [Back Pain Beliefs Questionnaire (BBQ); Fear Avoidance Beliefs Questionnaire (FABQ)]. Secondary outcomes included pain severity, activity impairment and pamphlet perceived usefulness. Blinding to group allocation included primary investigators, outcome assessors and the statistician. Pharmacy staff and consumers were un-blinded.

Results

Of 35 pharmacies recruited (317 consumers), no clusters were lost to follow-up. Follow-up was available for n = 24 at 2 weeks only; n = 38 at 8 weeks only; n = 148 at both time points, with n = 148+24+38 = 210 analysed (107 excluded: no follow up). Adjusting for baseline scores demonstrated no significant differences in beliefs (2 or at 8 weeks) between pamphlet (with or without education) versus control, or between ‘pamphlet with’ versus ‘without’ education. Work-related fear (FABQ) was significantly lower in consumers receiving pamphlet (with or without education) versus control (difference −2.3, 95%CI: −4.4 to −0.2). There was no significant difference between “pamphlet with” versus “pamphlet without” groups. Consumers receiving the “pamphlet with” reported greater perceived usefulness than consumers receiving the “pamphlet without” (difference 0.9 (95%CI: 0.0 to 1.8)).

Conclusion

Community pharmacies provided a feasible primary care portal for implementing evidence-based information. The associated improvement in work-related LBP-beliefs for consumers receiving the pamphlet suggests this simple intervention may be a useful component of care.

Cancer patients' and professional caregivers' needs, preferences and factors associated with receiving and providing fertility-related information: a mixed-methods systematic review

OBJECTIVES

Cancer treatment can impair fertility. The aim of this review was to investigate (1) fertility information needs, receipt and provision, (2) fertility information preferences, and (3) factors associated with receiving/providing fertility information. Cancer patients' and professional caregivers' perspectives were considered.

DESIGN

Mixed-methods systematic review.

DATA SOURCES

Six electronic databases (PubMed, Web of Science, CINAHL, CRD, Embase) were systematically screened to retrieve articles published between January 2001 and March 2012. Reference lists and conference abstracts were checked for additional publications.

REVIEW METHODS

The principles outlined in the Cochrane Handbook for Systematic Reviews of Intervention were applied. Publications were included if they explored fertility-related information/communication in cancer patients/survivors of reproductive age or professional caregivers. The Critical Appraisal Skills Programme for Qualitative Studies and the Quality Assessment Tool for Quantitative Studies were used to assess the methodological quality. A standardised form based on the Cochrane guidelines for systematic reviews was used to extract the data. Two independent reviewers performed all methodological steps.

RESULTS

Of the 1872 papers found, 27 were included in this review. The majority (66-100%) of the cancer patients wanted information about the impact of cancer therapy on fertility. The need and importance were higher in younger and childless patients, and in patients having childbearing plans. The number of patients receiving this information ranged from 0% to 85%. Several factors were associated with the lack of information receipt, including female gender and age 35 years or older. Patients preferred information via an individual consultation. In the diagnostic phase patients needed information about the impact of the treatment on fertility and preservation options. At the end or after the treatment, information needs shifted towards long term effects. Professional caregivers experienced several barriers in providing fertility information, including caregiver-, patient- and institutional-related factors. Nurses in particular, perceived difficulty in providing fertility-related information due to additional barriers associated with limited responsibility and opportunity in fertility information provision.

CONCLUSION

Professional caregivers experienced multiple barriers that hinder information provision. Further exploration of the role of Advanced Nurse Practitioners/Midwifes and the development of an evidence based intervention to overcome caregiver-related barriers are recommended to improve information provision.

Multimedia educational interventions for consumers about prescribed and over-the-counter medications

BACKGROUND

Health consumers increasingly want access to accurate, evidence-based information about their medications. Currently, education about medications (that is, information that is designed to achieve health or illness related learning) is provided predominantly via spoken communication between the health provider and consumer, sometimes supplemented with written materials. There is evidence, however, that current educational methods are not meeting consumer needs. Multimedia educational programs offer many potential advantages over traditional forms of education delivery.

OBJECTIVES

To assess the effects of multimedia patient education interventions about prescribed and over-the-counter medications in people of all ages, including children and carers.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2011, Issue 6), MEDLINE (1950 to June 2011), EMBASE (1974 to June 2011), CINAHL (1982 to June 2011), PsycINFO (1967 to June 2011), ERIC (1966 to June 2011), ProQuest Dissertation & Theses Database (to June 2011) and reference lists of articles.

SELECTION CRITERIA

Randomised controlled trials (RCTs) and quasi-RCTs of multimedia-based patient education about prescribed or over-the-counter medications in people of all ages, including children and carers, if the intervention had been targeted for their use.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed the risk of bias of included studies. Where possible, we contacted study authors to obtain missing information.

MAIN RESULTS

We identified 24 studies that enrolled a total of 8112 participants. However, there was significant heterogeneity in the comparators used and the outcomes measured, which limited the ability to pool data. Many of the studies did not report sufficient information in their methods to allow judgment of their risk of bias. From the information that was reported, three of the studies had a high risk of selection bias and one was at high risk of bias due to lack of blinding of the outcome assessors. None of the included studies reported the minimum clinically important difference for the outcomes that were measured. We have therefore reported results from the studies but have been unable to interpret whether differences were of clinical importance.The main findings of the review are as follows.Knowledge: There is low quality evidence that multimedia education was more effective than usual care (non-standardised education provided as part of usual clinical care) or no education (standardised mean difference (SMD) 1.04, 95% confidence interval (CI) 0.49 to 1.58, six studies with 817 participants). There was considerable statistical heterogeneity (I(2) = 89%), however, all but one of the studies favoured the multimedia group. There is moderate quality evidence that multimedia education was not more effective at improving knowledge than control multimedia interventions (i.e. multimedia programs that do not provide information about the medication) (mean difference (MD) of knowledge scores 2.78%, 95% CI -1.48 to 7.0, two studies with 568 participants). There is moderate quality evidence that multimedia education was more effective when added to a co-intervention (written information or brief standardised instructions provided by a health professional) compared with the co-intervention alone (MD of knowledge scores 24.59%, 95% CI 22.34 to 26.83, two studies with 381 participants).Skill acquisition: There is moderate quality evidence that multimedia education was more effective than usual care or no education (MD of inhaler technique score 18.32%, 95% CI 11.92 to 24.73, two studies with 94 participants) and written education (risk ratio (RR) of improved inhaler technique 2.14, 95% CI 1.33 to 3.44, two studies with 164 participants). There is very low quality evidence that multimedia education was equally effective as education by a health professional (MD of inhaler technique score -1.01%, 95% CI -15.75 to 13.72, three studies with 130 participants).Compliance with medications: There is moderate quality evidence that there was no difference between multimedia education and usual care or no education (RR of complying 1.02, 95% CI 0.96 to 1.08, two studies with 4552 participants).We could not determine the effect of multimedia education on other outcomes, including patient satisfaction, self-efficacy and health outcomes, due to an inadequate number of studies from which to draw conclusions.

AUTHORS' CONCLUSIONS

This review provides evidence that multimedia education about medications is more effective than usual care (non-standardised education provided by health professionals as part of usual clinical care) or no education, in improving both knowledge and skill acquisition. It also suggests that multimedia education is at least equivalent to other forms of education, including written education and education provided by a health professional. However, this finding is based on often low quality evidence from a small number of trials. Multimedia education about medications could therefore be considered as an adjunct to usual care but there is inadequate evidence to recommend it as a replacement for written education or education by a health professional. Multimedia education may be considered as an alternative to education provided by a health professional, particularly in settings where provision of detailed education by a health professional is not feasible. More studies evaluating multimedia educational interventions are required in order to increase confidence in the estimate of effect of the intervention.Conclusions regarding the effect of multimedia education were limited by the lack of information provided by study authors about the educational interventions, and variability in their content and quality. Studies testing educational interventions should provide detailed information about the interventions and comparators. Research is required to establish a framework that is specific for the evaluation of the quality of multimedia educational programs. Conclusions were also limited by the heterogeneity in the outcomes reported and the instruments used to measure them. Research is required to identify a core set of outcomes which should be measured when evaluating patient educational interventions. Future research should use consistent, reliable and validated outcome measures so that comparisons can be made between studies.

Getting the message across: opportunities and obstacles in effective communication in hypertension care

Effective communication is a prerequisite for any successful encounter between patient and provider. Nevertheless, it is unclear how/where communication can impact/affect adherence to antihypertensive medication, and maintenance of lifestyle changes to control blood pressure targets. Poor physician communication is correlated with a higher risk of treatment nonadherence. Given the high rates of hypertension globally, this review serves to enlighten aspects of the communication exchange from a provider, context, and patient perspective. Relevant articles were analyzed to assess barriers, solutions, and optimizations for communication with hypertensive patients. To support the findings, a model of communication in the context of hypertension treatment is presented, which comprises three phases: comprehension and acceptance, translation into action, and long-term retention. Secondly, an analysis of care providers (bedside manner, verbal/nonverbal communication, empathy and sex, time, knowledge base), context (format and tailoring of the message, and physical environment), and patient-related factors (sex, socio-economic status, language and health literacy, culture, age, psychological factors) were assessed in relation to hypertension. Current literature is limited regarding reciprocal communication, adaptive packaging of messages, and active verification of effective communication. To improve communication, hypertension care programs could benefit from better communication training, more team-based approaches, and flexible tools based on information technology.

Risk perception and medicines information needs in pregnant women with epilepsy--a qualitative study

PURPOSE

To explore risk perception and medicines information needs in pregnant women with epilepsy (WWE).

METHOD

In-depth interviews with pregnant WWE treated with antiepileptic drugs (AEDs).

RESULTS

Ten women aged 22-39 years in 20-34 weeks' gestation were interviewed. Avoiding seizures by taking AEDs in pregnancy outweighed perceived risks, but dose adjustments during and after pregnancy increased perceived risks of teratogenicity or seizures. The women had restrictive attitudes towards taking medicines for other indications than epilepsy. They appreciated their neurologist as a source for medicines information, though their needs for medicines information were reduced by long-term use of AEDs.

CONCLUSIONS

Pregnant WWE were confident in using AEDs through communication with their neurologist, but dose adjustments caused concern. Medicines information to pregnant WWE should focus on empowering the women to control the disease, supporting realistic risk perceptions of AEDs and other necessary medicines. In this article, we outline some medicines information strategies to pregnant WWE.

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.

Predictors for patient knowledge and reported behaviour regarding driving under the influence of medicines: a multi-country survey

BACKGROUND

Reports on the state of knowledge about medicines and driving showed an increased concern about the role that the use of medicines might play in car crashes. Much of patient knowledge regarding medicines comes from communications with healthcare professionals. This study, part of the DRUID (Driving Under the Influence of Drugs, alcohol and medicines) project, was carried out in four European countries and attempts to define predictors for knowledge of patients who use driving-impairing medicines. The influence of socio-demographic variables on patient knowledge was investigated as well as the influence of socio-demographic factors, knowledge and attitudes on patients' reported behaviour regarding driving under the influence of medicines.

METHODS

Pharmacists handed out questionnaires to patients who met the inclusion criteria: 1) prevalent user of benzodiazepines, antidepressants or first generation antihistamines for systemic use; 2) age between 18 and 75 years old and 3) actual driver of a motorised vehicle. Factors affecting knowledge and reported behaviour towards driving-impairing medicines were analysed by means of multiple linear regression analysis and multiple logistic regression analysis, respectively.

RESULTS

A total of 633 questionnaires (out of 3.607 that were distributed to patients) were analysed. Patient knowledge regarding driving under the influence of medicines is better in younger and higher educated patients. Information provided to or accessed by patients does not influence knowledge. Patients who experienced side effects and who have a negative attitude towards driving under the influence of impairing medicines are more prone to change their driving frequency behaviour than those who use their motorised vehicles on a daily basis or those who use anti-allergic medicines.

CONCLUSIONS

Changes in driving behaviour can be predicted by negative attitudes towards driving under the influence of medicines but not by patients' knowledge regarding driving under the influence of medicines. Future research should not only focus on information campaigns for patients but also for healthcare providers as this might contribute to improve communications with patients regarding the risks of driving under the influence of medicines.

Accepting the unacceptable: medication adherence and different types of action patterns among patients with high blood pressure

OBJECTIVE

To gain deep insight into what it means for patients to live with drug-treated hypertension and to understand the implications for the doctors' influence on patients' adherence.

METHODS

Group discussions with 43 drug-treated hypertensive patients. Documentary method was used for interpretative analysis.

RESULTS

Four basic phenomena were identified (fear, ignorance, reluctance to discuss matters with the doctor, impact of illness experiences), which resulted in different types of action patterns: (1) the assertive actor, (2) the unconscious avoider, and (3) the inconsistent actor. The types of action patterns do not refer to any implications for adherence. The patients' action does not indicate their preferred model of doctor-patient interaction or their acceptance of taking medication.

CONCLUSION

Adherence must not be seen as meaningless behaviour, which can simply be learned, but rather as the result of subjective experiences on living with hypertension and the ability to accept the diagnosis and its treatment.

PRACTICE IMPLICATIONS

It is premature to initiate therapy straight after the diagnosis, before the patient is prepared to take the tablets. Supporting adherence means to stay in dialogue and to give the time, privacy and patience to enable patients to overcome their inhibitions of asking and to accept the therapy.

An illustrated leaflet containing antiretroviral information targeted for low-literate readers: development and evaluation

OBJECTIVE

To apply a dual visual/textual modal approach in developing and evaluating a medicine information leaflet with pictograms suitable for low-literate HIV/AIDS patients. To identify and recommend best practices in this type of information design.

METHODS

A simple leaflet incorporating pictograms was designed for an antiretroviral regimen. Cognitive testing for understanding was conducted in 39 low-literate, South African, antiretroviral-naïve adults. Participants were required to locate and explain the information, and were questioned on their opinion of leaflet layout and contents.

RESULTS

Average understanding of the leaflet was 60%. Basic medication information was the best understood. An overall lack of knowledge of HIV/AIDS and its core concepts was found. Only half the participants considered this simple leaflet "easy" to read. All endorsed the inclusion of pictograms.

CONCLUSION

This testing method used in ARV-naïve individuals was invaluable in identifying areas needing modification before its use in patients. Text associated with pictograms was more noticeable and better understood, but only if they were closely juxtaposed.

PRACTICE IMPLICATIONS

Leaflet design should consider culture and literacy skills, be informed by learning theory and design principles, include visuals to enhance appeal and improve understanding, and involve end-users. Verbal counseling should accompany written information.

Developing written information on osteoarthritis for patients: facilitating user involvement by exposure to qualitative research

INTRODUCTION

In developing a guidebook on osteoarthritis (OA), we collaborated with people who have chronic joint pain (users). But to advise, users need to be aware of and sensitive about their own state of knowledge and educationalists argue that adults sometimes lack such awareness. This paper will report on our experience of providing users with findings from qualitative research to increase awareness of their level of knowledge.

METHOD

A summary of the results from qualitative research into people's experiences of living with chronic pain was sent to individual members of two groups of users. It was then used to structure group meetings held to help identify information needed for the guidebook.

FINDINGS

Some users found the summary difficult to read and suggested how to simplify it. Nevertheless, it helped most users to become aware of the experiences and views of others who have OA and thus become more sensitive to their own level of knowledge. It also helped them recall experiences that stimulated practical suggestions for managing joint pain in everyday life and provided a way of gently challenging the views of users when they appeared to assume that their views were widely held. The discussions brought to light gaps in the research literature.

CONCLUSION

We believe this way of involving users by exposing them to qualitative research findings about lay experiences of living with OA effectively facilitated the users' contributions to the needs of those who have to live with OA, and we believe it has wider applications.

Patients' experience of hospital pharmaceutical services

OBJECTIVE

This study aimed to investigate inpatients' and outpatients' need for information about medication, to what extent those needs were addressed and patient attitudes regarding pharmaceutical services.

METHOD

Self-administered questionnaires were distributed to a sample of outpatients and inpatients in a UK district general hospital. Themes included satisfaction with information given about medication, potential confusion over medication prescribed by the general practitioner and by the hospital, access to a member of the pharmacy team and preferences on how information on medication should be given.

KEY FINDINGS

Ninety-one outpatient and 126 inpatient questionnaires were available for analysis. All outpatients who responded acknowledged that they were told how long they might need to wait for their medicines to be dispensed, although approximately one-fifth felt they had to wait a long time. Nearly three-quarters of outpatients felt there was an opportunity to ask medication-related questions of the pharmacy team. Nearly three-quarters of inpatients reported they were encouraged to bring into any hospital any medication they were taking at home. Twenty-eight per cent of 95 inpatients reported that some of their existing medication was stopped while in hospital. For the inpatients who received information about new medication, this was explained to the patient verbally (76%) and both verbally and in writing (22%). Forty-two per cent of inpatients (and 36% of outpatients) expressed a preference to receive information about medication both verbally and in writing. Thirty-five (32%) of 110 inpatients were not aware that a pharmacy team had a presence on the ward.

CONCLUSIONS

Overall the majority of both in- and outpatients appeared to be receiving appropriate pharmaceutical services. There is a need to raise the profile of the pharmacy team in regards to provision of medication advice for inpatients. Consideration needs to be given to better provision of written information about medication for patients.

Making choices about support services: disabled adults' and older people's use of information

This paper explores how disabled adults and older people find and use information to help make choices about services. It presents findings from a qualitative longitudinal study in England. Thirty participants had support needs that fluctuated, meaning that additional services might be needed on a temporary basis; and 20 had the sudden onset of support needs resulting from an accident or rapid deterioration in health. Each disabled adult or older person was interviewed three times between 2007 and 2009, using a semi-structured topic guide. They were asked to discuss a recent choice about services, focussing, amongst other things, on their use of information. Interviews were transcribed and coded, then charted according to emergent themes. A wide range of choices and sources of information were discussed. These were dominated by health and to some extent by social care. Key findings are that information was valuable not just in weighing up different service options, but as a precondition for such choices, and that disabled adults and older people with the gradual onset of support needs and no prior knowledge about services can be disadvantaged by their lack of access to relevant information at this pre-choice stage. Timely access to information was also important, especially for people without the support of emergency or crisis management teams. Healthcare professionals were trusted sources of information but direct payment advisers appeared less so. Ensuring that practitioners are confident in their knowledge of direct payments, and have the communication skills to impart that knowledge, is essential. There may be a role also for specialist information advocates or expert lay-advisers in enabling disabled adults and older people to access and consider information about choices at relevant times.

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.

Developing and testing a patient information booklet for thrombolysis used in acute stroke

Objective  Thrombolysis decreases the chance of post-stroke dependence, although its use carries significant risk, notably of intra-cerebral haemorrhage. Patients (and families) face an important risk/benefit decision before consenting. We drafted a patient information booklet for this purpose, and applied performance-based readability testing with the aim that the most important information in the booklet could be found and understood. Methods  The booklet was developed with reference to best practice in information writing and design. We User-Tested its performance on 56 people without prior experience of stroke. After reading the booklet they were asked to find and explain 15 pieces of information. The booklet was revised according to its performance and re-tested, until each item was found and understood by at least 80% of participants. Key findings  The four-page information booklet contained approximately 900 words, organised into six sections. A risk-palette graphic showed the chance of positive and negative outcomes. The booklet was tested on four participant cohorts and revised, including more bold text, re-wording, changing the title and changing the graphic to a coloured bar chart. Testing the final version on the fourth cohort of 20 people showed that each of the 15 tested items of information met the target of at least 80% participants being able to find and understand it. Conclusions  The use of information design and User Testing produced a booklet that is understandable by people with no prior experience of stroke. User Testing is an inexpensive and quick method to ensure that information intended for patients is usable.

Communicating the risk of side effects to patients: an evaluation of UK regulatory recommendations

BACKGROUND

All licensed medicines in the European Union must be provided with a Patient Information Leaflet that includes a list of all known side effects. Among patients who read the leaflet, the side effects section is the most often read. A UK government regulatory publication recommends providing medicine side effect risk information in a combined format, using verbal descriptors accompanied by numerical information.

OBJECTIVES

This study, with users of an existing popular patient information website, investigates the effectiveness of presenting medicine side effect risk information in different forms.

DESIGN

Participants were randomly allocated to one of the three formats for representing risk information (verbal descriptors, e.g. 'common'; absolute frequencies, e.g. 'less than 1 in 10 people'; and a combination of verbal descriptors and frequency bands, e.g. 'common (affects less than 1 in 10 people)'.

METHODS

Participants (n = 187) were recruited from users of the Cancer Research UK patient information website. They were asked to imagine that they had to take a cancer treatment (tamoxifen), estimate the risks of four side effects occurring, and complete Likert scales relating to their satisfaction with the information supplied and perceived likelihood of various outcomes.

RESULTS

Those in the absolute frequency format demonstrated greater accuracy in estimating the likelihood of having two of four side effects than the other two formats. They were also more accurate at estimating the likelihood of themselves or the average person having any side effect from taking tamoxifen. Participants in the absolute frequency format rated the risk to health from tamoxifen as lower than those in the other two formats, were more satisfied with the information they received than those in the verbal format, and felt there would be less impact of the information on tamoxifen use than those in the combined format.

CONCLUSIONS

These findings fail to confirm that the recommended use of combined descriptors for medicine side effects is unequivocally superior to absolute frequency alone. They also add weight to the growing body of research highlighting the deficiencies in using verbal descriptors for conveying side effect risk, and the strength of using absolute frequency descriptors.

Patient assessment of medication information leaflets and validation of the Evaluative Linguistic Framework (ELF)

OBJECTIVE

To obtain patient feedback about the structure and quality of medication information leaflets and validate the usefulness of the Evaluative Linguistic Framework (ELF) for improving written communication with patients.

METHODS

Triangulated feedback about a set of rheumatoid arthritis (RA) medication leaflets, some developed with knowledge of the ELF, was obtained from 27 people with RA from interviews, focus group discussion and self-administered questionnaires. The principal elements of the framework were investigated: overall generic structure and functions of each stage, interpersonal relationship between writer and reader, technicality of language and density of information.

RESULTS

Participant assessments of the leaflets aligned with the framework in terms of what constituted a good leaflet. While the main purpose of the leaflets was identified as being information provision, participants also wanted clear instructions, benefits to be highlighted and side effects to be comprehensively listed. For comprehensiveness and user-friendliness, leaflets developed with guidance of the ELF were consistently preferred.

CONCLUSION

According to people with RA, leaflets generated from a linguistic framework are clearer and more effective in communicating information about medications.

PRACTICE IMPLICATIONS

The ELF is a user-friendly, structured analytic system that can assist with the development of effective high quality patient information materials.

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.

Information and behavioural instruction along the health-care pathway: the perspective of people undergoing hernia repair surgery and the role of formal and informal information sources

BACKGROUND

Provision of information and behavioural instruction has been demonstrated to improve recovery after surgery. However, patients draw on a range of information sources and it is important to establish which sources patients use and how this influences perceptions and behaviour as they progress along the surgical pathway. In this qualitative, exploratory and longitudinal study, the use of information and instruction were explored from the perspective of people undergoing inguinal hernia repair surgery.

METHODS

Seven participants undergoing inguinal hernia repair surgery were interviewed using semi-structured interviews 2 weeks before surgery and 2 weeks and 4 months post-surgery. Nineteen interviews were conducted in total. Topic guides included sources of knowledge, reasons for help-seeking and opting for surgery and factors influencing return to activity. Data were analysed thematically according to Interpretative Phenomenological Analysis.

FINDINGS AND CONCLUSIONS

Participants sought information from a range of sources, focusing on informal information sources before surgery and using information and instruction from health-care professionals post-surgery. This information influenced behaviours including deciding to undergo surgery, use of pain medication and returning to usual activity. Anxiety and help-seeking resulted when unexpected post-surgical events occurred such as extensive bruising. Findings were consistent with psychological and sociological theories. Overall, participants were positive about the information and instruction they received but expressed a desire for more timely information on post-operative adverse events.

Adequacy of patient information on adverse effects: an assessment of patient information leaflets in the UK

BACKGROUND

One of the most important categories of information that patients want to know about the drug they are taking is the likelihood or probability of adverse effects. All patients should receive such information in the patient information leaflet that is supplied with all drugs. Anecdotal evidence suggests that most leaflets give little indication of the likelihood of adverse effects. The UK Medicines and Healthcare products Regulatory Agency (MHRA) suggests using a combination of words and numbers to convey this information. However, an EU guideline suggests using five verbal descriptors on a scale from common to rare, the use of which has been shown to lead to gross overestimation of the risk of adverse effects.

METHODS

We assessed the leaflets supplied with the 50 most frequently prescribed drugs in England, to determine the extent to which the likelihood of adverse effects was described, and whether it met the requirements of the EU guidance and/or best practice. We examined both the method used to describe the likelihood of adverse effects, and the format of this information in the leaflet.

RESULTS

Twenty of the 50 leaflets (40%) gave no indication of the likelihood of adverse effects occurring. Six (12%) used the recommended EU terms and a further 20 (40%) used a wide range of other verbal descriptors. Only four leaflets (8%) provided any form of numerical indication of risk. Over half (52%) presented long lists of adverse effects in paragraphs of continuous text.

CONCLUSIONS

Patient need is not being met in terms of the provision of usable information about the likelihood of adverse effects. Most patients receive no information, whereas some are given verbal descriptors, both of which lead to overestimation of the risk. Very few of the patient information leaflets assessed used currently described best practice, i.e. to present verbal descriptions alongside numerical information in the form of natural frequencies, e.g. 'rare (affects less than 1 in 1000 people)'.
