RESUMO

The integration of the Internet of Things (IoT) and the telecare medical information system (TMIS) enables patients to receive timely and convenient healthcare services regardless of their location or time zone. Since the Internet serves as the key hub for connection and data sharing, its open nature presents security and privacy concerns and should be considered when integrating this technology into the current global healthcare system. Cybercriminals target the TMIS because it holds a lot of sensitive patient data, including medical records, personal information, and financial information. As a result, when developing a trustworthy TMIS, strict security procedures are required to deal with these concerns. Several researchers have proposed smart card-based mutual authentication methods to prevent such security attacks, indicating that this will be the preferred method for TMIS security with the IoT. In the existing literature, such methods are typically developed using computationally expensive procedures, such as bilinear pairing, elliptic curve operations, etc., which are unsuitable for biomedical devices with limited resources. Using the concept of hyperelliptic curve cryptography (HECC), we propose a new solution: a smart card-based two-factor mutual authentication scheme. In this new scheme, HECC's finest properties, such as compact parameters and key sizes, are utilized to enhance the real-time performance of an IoT-based TMIS system. The results of a security analysis indicate that the newly contributed scheme is resistant to a wide variety of cryptographic attacks. A comparison of computation and communication costs demonstrates that the proposed scheme is more cost-effective than existing schemes.

RESUMO

BACKGROUND: Dispensed prescription medicine labels (prescription labels) are important information sources supporting safe and appropriate medicines use. OBJECTIVE: To develop and user test patient-centred prescription label formats. METHODS: Five stages: developing 12 labels for four fictitious medicines of varying dosage forms; diagnostic user testing of labels (Round 1) with 40 consumers (each testing three labels); iterative label revision, and development of Round 2 labels (n = 7); user testing of labels (Round 2) with 20 consumers (each testing four labels); labelling recommendations. Evaluated labels stated the active ingredient and brand name, using various design features (eg upper case and bold). Dosing was expressed differently across labels: frequency of doses/day, approximate times of day (eg morning), explicit times (eg 7 to 9 AM), and/or explicit dosing interval. Participants' ability to find and understand medicines information and plan a dosing schedule were assessed. RESULTS: Participants demonstrated satisfactory ability to find and understand the dosage for all label formats. Excluding active ingredient and dosing schedule, 14/19 labels (8/12 in Round 1; 6/7 in Round 2) met industry standard on performance. Participants' ability to correctly identify the active ingredient varied, with clear medicine name sign-posting enabling all participants evaluating these labels to find and understand the active ingredient. When planning a dosing schedule, doses were correctly spaced if the label stated a dosing interval, or frequency of doses/day. Two-thirds planned appropriate dosing schedules using a dosing table. CONCLUSIONS: Effective prescription label formatting and sign-posting of active ingredient improved communication of information on labels, potentially supporting safe medicines use. PATIENT AND PUBLIC INVOLVEMENT: Consumers actively contributed to the development of dispensed prescription medicine labels. Feedback from consumers following the first round was incorporated in revisions of the labels for the next round. Patient and public involvement in this study was critical to the development of readable and understandable dispensed prescription medicine labels.

RESUMO

Modern network technology yields new interface for telecare medicine information systems in short TMIS used for patient's healthcare. This system is used to provide healthcare services to patients at their home. It can be observed, telecare medicine information systems generally suffer several attacks as information being transmitted over a public network. Therefore, various authentication and key agreement schemes are proposed for TMIS to ensure secure and authorized patients communication over given public network. However, most of the schemes fail to achieve essential attributes discussed in this article. Although the key attributes of security and efficiency should be achieved in a common framework. This paper proposes construction of an RSA based authentication scheme for authorized access to healthcare services and achieves desirable key attributes of authentication protocols. Proof of security against polynomial time adversary is given in the random oracle to justify the security of proposed scheme. Communication analysis and computation analysis of proposed scheme indicates that proposed scheme's performance is comparable and having better security.

RESUMO

BACKGROUND: Involving patients in decisions about their pharmacotherapy is crucial for a satisfactory treatment outcome. Information and opinions about medicines are available from a variety of sources. The Wise List is the drug formulary of recommended essential medicines for the Stockholm healthcare region and is issued by the Drug and Therapeutics Committee (DTC). To inform the public about treatment for common diseases and the concept of recommended medicines, a patient edition of the Wise List was developed. The aim of this study was to explore patients' knowledge, needs and attitudes to the Wise List, DTC and information about medicines in general. METHODS: To examine patient knowledge about recommended medicines a survey (n = 312) was carried out at four large primary healthcare centres in Stockholm, Sweden. To further elucidate the patients' needs of the information on recommended medicines and medicines in general, three focus group discussions (FGDs) were performed. RESULTS: Of the respondents 57% did not recognise the Wise List, 26% recognised but did not use it and 17% used it. A total of 63% reported that they search for information about medicines. The most common information source was "asking their doctor" (36%) followed by searching the internet (31%). The FGDs revealed that the patients were not interested in medicines in general, only in the medicines they use themselves. They did not understand the aim of the Wise List or how they could benefit from information about recommended medicines. The patients expressed a wish to access all information they need about their own care as well as public healthcare information at one location. CONCLUSION: The intended aim of the DTC with providing information to the public was not achieved as the patients have difficulties to understand the information and how they should use it. The patients were not interested in medicines in general, they wanted information tailored to their specific needs. The findings highlight the importance of creating tools for patients in collaboration with them and evaluate the concept continuously.

RESUMO

E-Healthcare is an emerging field that provides mobility to its users. The protected health information of the users are stored at a remote server (Telecare Medical Information System) and can be accessed by the users at anytime. Many authentication protocols have been proposed to ensure the secure authenticated access to the Telecare Medical Information System. These protocols are designed to provide certain properties such as: anonymity, untraceability, unlinkability, privacy, confidentiality, availability and integrity. They also aim to build a key exchange mechanism, which provides security against some attacks such as: identity theft, password guessing, denial of service, impersonation and insider attacks. This paper reviews these proposed authentication protocols and discusses their strengths and weaknesses in terms of ensured security and privacy properties, and computation cost. The schemes are divided in three broad categories of one-factor, two-factor and three-factor authentication schemes. Inter-category and intra-category comparison has been performed for these schemes and based on the derived results we propose future directions and recommendations that can be very helpful to the researchers who work on the design and implementation of authentication protocols.

RESUMO

Unlike the traditional medical system, telecare medicine information system (TMIS) ensures that patients can get health-care services via the Internet at home. Authenticated key agreement protocol is very important for protecting the security in TMIS. Recently scholars have proposed a lot of authenticated key agreement protocols. In 2016, Chiou et al. demonstrated that Chen et al.'s authentication scheme fails to provide user's anonymity and message authentication and then proposed an enhanced scheme (Chiou et al., J. Med. Syst. 40(4):1-15, 2006) to overcome these drawbacks. In this paper, we demonstrate that Chiou et al.'s scheme is defenseless against key compromise impersonation (KCI) attack and also fails to provide forward security. Moreover, we propose a novel authentication scheme namely ICASME to overcome the mentioned weaknesses in this paper. Security analyses show that ICASME achieves the forward security and KCI attack resistance. In addition, it is proved that the time taken to implement the ICASME is not intolerable compared to the original protocol.

RESUMO

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.

RESUMO

Authentication and key agreement schemes play a very important role in enhancing the level of security of telecare medicine information systems (TMISs). Recently, Amin and Biswas demonstrated that the authentication scheme proposed by Giri et al. is vulnerable to off-line password guessing attacks and privileged insider attacks and also does not provide user anonymity. They also proposed an improved authentication scheme, claiming that it resists various security attacks. However, this paper demonstrates that Amin and Biswas's scheme is defenseless against off-line password guessing attacks and replay attacks and also does not provide perfect forward secrecy. This paper also shows that Giri et al.'s scheme not only suffers from the weaknesses pointed out by Amin and Biswas, but it also is vulnerable to replay attacks and does not provide perfect forward secrecy. Moreover, this paper proposes a novel authentication and key agreement scheme to overcome the mentioned weaknesses. Security and performance analyses show that the proposed scheme not only overcomes the mentioned security weaknesses, but also is more efficient than the previous schemes.

RESUMO

Recently, numerous extended chaotic map-based password authentication schemes that employ smart card technology were proposed for Telecare Medical Information Systems (TMISs). In 2015, Lu et al. used Li et al.'s scheme as a basis to propose a password authentication scheme for TMISs that is based on biometrics and smart card technology and employs extended chaotic maps. Lu et al. demonstrated that Li et al.'s scheme comprises some weaknesses such as those regarding a violation of the session-key security, a vulnerability to the user impersonation attack, and a lack of local verification. In this paper, however, we show that Lu et al.'s scheme is still insecure with respect to issues such as a violation of the session-key security, and that it is vulnerable to both the outsider attack and the impersonation attack. To overcome these drawbacks, we retain the useful properties of Lu et al.'s scheme to propose a new password authentication scheme that is based on smart card technology and requires the use of chaotic maps. Then, we show that our proposed scheme is more secure and efficient and supports security properties.

RESUMO

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.

RESUMO

Background: Verbal and written medicine information are available to the public but the quality, ease of access, ease of understanding and use of these resources varies greatly between countries. Timely access to quality medicine information is essential to support patient safety. Objective: This international cross-sectional survey, conducted in low-to high-income countries, aimed to compare experiences of and preferences for medicine information sources among respondents with recent medicine use. Methods: The survey was originally developed in England (Kent), then adapted and translated for use in southern Thailand (Songkhla), Malaysia (Klang Valley), and central Uganda (Kampala). Data were analysed using simple descriptive statistics and Chi-squared tests. Results: A total 1588 respondents were involved in the study. Community pharmacies were the primary source of medicines in all four countries (40.7 to 65.3%). Most respondents (1460; 92%) had received at least one form of information with their medicine, but provision of written medicine information (WMI) varied between countries. A manufacturer's leaflet was the most frequent information source for patients in England, while verbal information was common in Thailand, Malaysia and Uganda. There was commonality across countries in the desire for verbal information with or without WMI (1330; 84.8%); aspects of medicine information wanted most frequently were instructions on medicine use (98.3%), indication (98.2%), name (94.4%) and possible side effects (94.3%); and the importance of providing leaflets with all medicines (87.5%). Fewer than 10% in Uganda would use internet based WMI, compared to between 20% and 55% elsewhere. Conclusion: Preferences for medicine information are similar across countries: verbal information is seen as most desirable, and the most wanted aspects of information are common internationally. Accessibility and understandability are key influences on preferred information sources. In-country regulations and practices should ensure that all medicine users can access the information necessary to maximise safe medicine use.

RESUMO

OBJECTIVE: To provide an overview of inpatients' information needs about medication, including the best moment to provide this information, how, by whom and what patient characteristics influence these needs. METHODS: A systematic literature review was conducted. Studies that reported the information needs from inpatients about medication were included from Medline and Embase. The Crowe critical appraisal tool (CCAT) was used to assess the quality of the studies. RESULTS: Initially, 710 records were retrieved from Medline and Embase. After the forward search, another 609 records were screened and in total, 26 articles were included. The CCAT scores ranged from 17 to 34 points on a 40 point scale and two articles received 0 points. CONCLUSION: Inpatients main needs about medicine information are information about adverse and beneficial effects of medication, and general rules about how to take medication. Preferably, this information is printed and provided at the time of prescribing by a physician that already has a relationship with the patient. The most recent studies show that patients are open to the use of modern technology. PRACTICE IMPLICATIONS: This review provides a starting point for providing medicine information to inpatients. Further research should focus on patient characteristics influencing these information needs.

RESUMO

Objectives: This study aimed to analyze the general public's awareness of medicine information, safety, and adverse drug reactions in Quetta, Pakistan. Methods: A cross-sectional descriptive study was conducted using random sampling from April 2020 to April 2021 in Quetta. Samples were collected from respondents who met the inclusion criteria and had visited community pharmacies. The analysis was done using SPSS version 23. Bivariate and multivariate analyses were performed to assess factors associated with good knowledge. Results: Multivariate analysis revealed that purchase on prescription was a determining factor of knowledge regarding knowledge of pharmaceutical products and their provided information, medicines usage and safety, and Medication ADRs. Patients who bought medicines on prescriptions were more likely to have better knowledge. Patients having education were more likely to have better knowledge. Conclusion: Public awareness about medicine information, safety, and the information provided by manufacturers is crucial to ensuring that patients have access to accurate information about their medications and can make informed decisions about their health. Healthcare providers and regulatory bodies must work together to improve access to information and promote safe medication practices.

RESUMO

Producing health information that people can easily understand is challenging and time-consuming. Existing guidance is often subjective and lacks specificity. With advances in software that reads and analyzes text, there is an opportunity to develop tools that provide objective, specific, and automated guidance on the complexity of health information. This paper outlines the development of the SHeLL (Sydney Health Literacy Lab) Health Literacy Editor, an automated tool to facilitate the implementation of health literacy guidelines for the production of easy-to-read written health information. Target users were any person or organization that develops consumer-facing education materials, with or without prior experience with health literacy concepts. Anticipated users included health professionals, staff, and government and nongovernment agencies. To develop this tool, existing health literacy and relevant writing guidelines were collated. Items amenable to programmable automated assessment were incorporated into the Editor. A set of natural language processing methods were also adapted for use in the SHeLL Editor, though the approach was primarily procedural (rule-based). As a result of this process, the Editor comprises 6 assessments: readability (school grade reading score calculated using the Simple Measure of Gobbledygook (SMOG)), complex language (percentage of the text that contains public health thesaurus entries, words that are uncommon in English, or acronyms), passive voice, text structure (eg, use of long paragraphs), lexical density and diversity, and person-centered language. These are presented as global scores, with additional, more specific feedback flagged in the text itself. Feedback is provided in real-time so that users can iteratively revise and improve the text. The design also includes a "text preparation" mode, which allows users to quickly make adjustments to ensure accurate calculation of readability. A hierarchy of assessments also helps users prioritize the most important feedback. Lastly, the Editor has a function that exports the analysis and revised text. The SHeLL Health Literacy Editor is a new tool that can help improve the quality and safety of written health information. It provides objective, immediate feedback on a range of factors, complementing readability with other less widely used but important objective assessments such as complex and person-centered language. It can be used as a scalable intervention to support the uptake of health literacy guidelines by health services and providers of health information. This early prototype can be further refined by expanding the thesaurus and leveraging new machine learning methods for assessing the complexity of the written text. User-testing with health professionals is needed before evaluating the Editor's ability to improve the health literacy of written health information and evaluating its implementation into existing Australian health services.

RESUMO

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.

RESUMO

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.

RESUMO

Background: Package leaflet provides information about medicinal product to the user. Printed leaflet is familiar and available, however poorly legible, especially when containing multiple languages. It is resourceful to update, has potential to go missing or get damaged, and is environmentally burdensome. The pharmaceutical manufacturers in the Baltic countries have been granted permission to market selected hospital medicinal products without printed package leaflet. The industrial pilot project is expected to promote availability of medicinal products and patient safety via increased access to medicinal information. Objective: Only few countries in Europe have derogated from Article 58 of Directive 2001/83/EC. Knowledge about the effects of removal of paper package leaflet from the medicinal product is limited, and related publications are scarce. Current interview study is identifying the obstacles during the implementation of the industrial project, investigating the potential environmental impact, and searching for further opportunities for the package leaflet in development of medicinal products. Methods: Real-time person-to-person semi-structured interviews with relevant stakeholders were conducted, and transcripts were analysed by content analysis to identify themes. Results: Results demonstrated general support for removing package leaflet from selected hospital products. Main difficulties of the industrial project regarded the need for clear communication and practical disadvantages of project setup. Main benefits included educational aspect of increasing awareness about product information and strengthened collaboration. Majority of participants felt doubtful about the impact of the industrial project on people's awareness of ecological issues and they admittedly lacked sufficient information on the environmental impact of pharmaceutical packaging. Conclusion: The removal of paper leaflet could be extended to more products based on the positive feedback for the industrial pilot project. However, it is paramount that the format of electronic product information would need to be enhanced first to improve readability.

RESUMO

BACKGROUND: Despite the prevalence of over-the-counter medicine advertising (OTCA) in electronic and print media, scholarly focus has tended to concentrate on direct-to-consumer prescription medicine advertising (DTCA). OBJECTIVES: The purpose of this study is to examine the mechanisms through which attitudes toward OTCA in general and OTCA prompted behaviors are formed based on a consumer socialization framework. METHODS: An online survey was conducted as part of a larger medicine and pharmaceutical advertising project using the Qualtrics online panel. A total of 819 individuals who had taken a prescription medicine in the last six months participated in the survey and yielded 539 completed questionnaires (Completion rate: 65.8%). Of those, 304 responses from U.S. adults who had taken an OTC medicine and had seen an advertisement for OTC medicines in the past six months were analyzed to test the proposed model. A series of structural equation modeling analyses of the survey data was performed. RESULTS: The study results showed that consumers' use of mass media and professional interpersonal channels directly influenced attitudes toward OTCA and OTCA prompted behaviors. On the other hand, consumers' use of non-professional interpersonal channels indirectly influenced OTCA outcomes through their use of mass media and professional interpersonal channels. Younger respondents were more likely to obtain OTC medicine information from non-professional interpersonal and mass media sources whereas older respondents were more likely to obtain OTC medicine information from physicians and pharmacists. CONCLUSIONS: Application of the consumer socialization framework in the context of OTCA provides expanded understanding of the mechanisms through which responses to OTCA are formed.

RESUMO

OBJECTIVE: The nocebo effect is the adverse effects of treatment that cannot be attributed to a medicine. We investigated if we could increase or decrease nocebo responding following medicine taking. A nocebo explanation to reduce side effects was compared with a negative medication news item designed to increase side effects and a control condition. METHODS: 108 healthy participants enrolled in a between-subjects study purportedly testing the effect of lamotrigine (actually placebo) on mood and cognition. Participants were randomised to watch either a video explaining the nocebo effect; a negative media item on lamotrigine, or control video prior to receiving the tablet. Side effects were assessed at 45-min and 48-h. RESULTS: The negative media group reported significantly more side effects (M = 0.78, SD = 1.53) than the control group (M = 0.46, SD = 1.80, p = .035) at the end of session and a greater proportion of the negative media group (33%) reported at least one side effect compared to the nocebo explanation (11%) and control group (11%, p = .020). The nocebo explanation group reported significantly fewer side effects (M = 0.38, SD = 1.16) than the control group (M = 1.37, SD = 2.98, p = .038) at the 48-h follow-up. CONCLUSION: Explaining the nocebo effect may be a beneficial addition to standard medicine information for reducing side effect reporting. Negative media coverage about a drug is likely to generate increased side effects. Future research should examine the benefit of nocebo explanation in patients starting new medicines.
