Patients' Knowledge of Key Messaging in Drug Safety Communications for Zolpidem and Eszopiclone: A National Survey.

Drug Safety Communications (DSCs) are used by the Food and Drug Administration (FDA) to inform health care providers, patients, caregivers, and the general public about safety issues related to FDA-approved drugs. To assess patient knowledge of the messaging contained in DSCs related to the sleep aids zolpidem and eszopiclone, we conducted a large, cross-sectional patient survey of 1,982 commercially insured patients selected by stratified random sampling from the Optum Research Database who had filled at least two prescriptions for either zolpidem or eszopiclone between July 1, 2012 and June 30, 2013. Among the 594 respondents (32.7% response rate), two-thirds reported hearing generally about drug safety information prior to starting a new drug, with the remaining one-third "rarely" or "never" hearing such information. Providers and pharmacists were primary sources of drug safety information. Two-thirds of zolpidem users and half of eszopiclone users reported having heard about the related DSC messages, ability to accurately identify the major factual messages was limited (overall median 2 correct out of 5, with men and those reporting higher educational level scoring higher [2/5 vs. 1/5, p=0.001]). Respondents reacted to new drug safety information about their sleep aids by reporting that they would want to learn about alternative ways to help them sleep (70%) and seek out more information about the safety of their specific sleeping pill (59-78%). Opportunities may exist for the FDA to work with providers and pharmacies to help ensure the DSC information is more widely received and is more fully understood by those taking the affected medications.

Multimodal Analysis of FDA Drug Safety Communications: Lessons from Zolpidem.

Because clinical trials conducted for US Food and Drug Administration (FDA) approval occur in carefully monitored settings and often have strict inclusion criteria for participation, new information about drug safety is commonly discovered once a medication is FDA approved and used by larger numbers of patients. The FDA issues Drug Safety Communications when new information arises about the safety of marketed drugs that may change decision making by healthcare providers and patients. Since their inception, over 250 Drug Safety Communications have been issued alerting consumers and prescribers in the USA about safety risks related to prescription and over-the-counter medications. Researchers at the Brigham and Women's Hospital in Boston in conjunction with officials from the FDA undertook a multi-modal study of the content, dissemination, and uptake of FDA messaging, focusing on two 2013 Drug Safety Communications related to zolpidem (Ambien; Sanofi, Paris, France). Traditional and social media analyses note incomplete dissemination of key DSC messages. Surveys of patients and interviews of physicians and patients suggest important limitations in patient-provider communication that have hindered sharing of safety information with patients. Finally, pharmacoepidemiologic analyses of zolpidem dispensing patterns after the Drug Safety Communications were released suggest possible opportunities for enhancing uptake of new safety knowledge that may lead to changes in clinical practice, where appropriate.

Children and Adults With Rare Diseases Need Innovative Medical Devices.

Rare diseases (RD) affect approximately 30 million Americans, half of whom are children. This study is the first to comprehensively evaluate their medical device needs via a survey of physicians. The study sought to identify and document the presumed unmet diagnostic and therapeutic device needs for RD management; clarify the magnitude of the potential unmet need; and generate meaningful data to inform medical device stakeholders. A cross-sectional nonprobability survey was conducted. The study population was drawn from the membership files of four groups: FDA Medical Devices Advisory Committee, Pediatric Advisory Committee, Pediatric Device Consortia, and National Institutes of Health (NIH) Rare Diseases Clinical Research Network. Only physician respondents with experience or knowledge regarding RD were eligible. Among eligible respondents, 90% confirmed the need for innovative devices to care for people with RD. Over 850 device needs were identified for 436 RD, with 74% of needs related to children. Pediatric physicians (OR = 2.11, 95% CI 1.01-4.39, P = 0.046) and physicians with more RD experience reflected greater dissatisfaction with existing devices (OR = 4.49, 95% CI 2.25-8.96, P < 0.0001). Creation of entirely new devices is the top recommendation for mitigating needs. This study demonstrates a major public health need for innovative medical devices to care for children and adults with RD. FDA and NIH support and seek opportunities to accelerate device development for these vulnerable patients.

Social Media Impact of the Food and Drug Administration's Drug Safety Communication Messaging About Zolpidem: Mixed-Methods Analysis.

BACKGROUND: The Food and Drug Administration (FDA) issues drug safety communications (DSCs) to health care professionals, patients, and the public when safety issues emerge related to FDA-approved drug products. These safety messages are disseminated through social media to ensure broad uptake. OBJECTIVE: The objective of this study was to assess the social media dissemination of 2 DSCs released in 2013 for the sleep aid zolpidem. METHODS: We used the MedWatcher Social program and the DataSift historic query tool to aggregate Twitter and Facebook posts from October 1, 2012 through August 31, 2013, a period beginning approximately 3 months before the first DSC and ending 3 months after the second. Posts were categorized as (1) junk, (2) mention, and (3) adverse event (AE) based on a score between -0.2 (completely unrelated) to 1 (perfectly related). We also looked at Google Trends data and Wikipedia edits for the same time period. Google Trends search volume is scaled on a range of 0 to 100 and includes "Related queries" during the relevant time periods. An interrupted time series (ITS) analysis assessed the impact of DSCs on the counts of posts with specific mention of zolpidem-containing products. Chow tests for known structural breaks were conducted on data from Twitter, Facebook, and Google Trends. Finally, Wikipedia edits were pulled from the website's editorial history, which lists all revisions to a given page and the editor's identity. RESULTS: In total, 174,286 Twitter posts and 59,641 Facebook posts met entry criteria. Of those, 16.63% (28,989/174,286) of Twitter posts and 25.91% (15,453/59,641) of Facebook posts were labeled as junk and excluded. AEs and mentions represented 9.21% (16,051/174,286) and 74.16% (129,246/174,286) of Twitter posts and 5.11% (3,050/59,641) and 68.98% (41,138/59,641) of Facebook posts, respectively. Total daily counts of posts about zolpidem-containing products increased on Twitter and Facebook on the day of the first DSC; Google searches increased on the week of the first DSC. ITS analyses demonstrated variability but pointed to an increase in interest around the first DSC. Chow tests were significant (P<.0001) for both DSCs on Facebook and Twitter, but only the first DSC on Google Trends. Wikipedia edits occurred soon after each DSC release, citing news articles rather than the DSC itself and presenting content that needed subsequent revisions for accuracy. CONCLUSIONS: Social media offers challenges and opportunities for dissemination of the DSC messages. The FDA could consider strategies for more actively disseminating DSC safety information through social media platforms, particularly when announcements require updating. The FDA may also benefit from directly contributing content to websites like Wikipedia that are frequently accessed for drug-related information.

Patient and Physician Perceptions of Drug Safety Information for Sleep Aids: A Qualitative Study.

INTRODUCTION: The US Food and Drug Administration uses drug safety communications (DSCs) to release emerging information regarding post-market safety issues, but it is unclear the extent of awareness by patients and providers of these communications and their specific recommendations. OBJECTIVE: We conducted semi-structured interviews with patients and physicians to evaluate their awareness and understanding of emerging drug safety information related to two sleep aids: zolpidem or eszopiclone. METHODS: We conducted interviews with 40 patients and ten physicians recruited from a combination of insurer claims databases and online sources. We evaluated (1) sources of drug safety information; (2) discussions between patients and physicians about the two medications; (3) their knowledge of the DSC; and (4) preferences for learning about future drug safety information. Interviews were transcribed and analyzed thematically. RESULTS: Patients cited their physicians, pharmacy inserts, and the Internet as sources of drug safety information. Physicians often referred to medical journals and online medical sources. Most patients reported being aware of information contained in the DSC summaries they were read. Almost all patients and physicians reported discussing side effects during patient-provider conversations, but almost no patients mentioned that physicians had communicated with them key messaging from the DSCs at issue: the risk of next-morning impairment with zolpidem and the lower recommended initial dose for women. CONCLUSIONS: Some risks of medications are effectively communicated to patients and physicians; however, there is still a noticeable gap between information issued by the Food and Drug Administration and patient and physician awareness of this knowledge, as well as patients' decisions to act on this information. Disseminators of emerging drug safety information should explore ways of providing user-friendly resources to patients and healthcare professionals that can update them on new risks in a timely manner.

Methodological approaches to evaluate the impact of FDA drug safety communications.

BACKGROUND: When the US FDA approves a new prescription drug there is still a great deal remaining to be learned about the safe and proper use of that product. When new information addressing these topics emerges post-approval, the FDA may issue a Drug Safety Communication (DSC) to alert patients and physicians. The effectiveness of the communication-how drug safety messaging conveyed in FDA DSCs changes patient or prescriber behavior-may depend on multiple factors, including the way physicians and patients learn about the information, their understanding of the issues conveyed, and their perception of the importance of the information. In 2013, the FDA issued two DSCs addressing critical new warnings related to products containing the sedative/hypnotic zolpidem. OBJECTIVE: In this article, we describe a core set of research initiatives that can be used to study how zolpidem-related DSCs affected subsequent physician and patient decision making. METHODS: These research initiatives include analyzing drug utilization patterns and related health outcomes; comparing zolpidem-containing products against a comparator with similar indications [eszopiclone (Lunesta)] not covered by the 2013 DSCs; and surveying patients and qualitatively evaluating the dissemination of information regarding these drugs in traditional and social-media channels. CONCLUSIONS: Using an integrated, multidisciplinary approach, we can obtain information that can be used to optimize regulatory communications by seeking to understand the impact of the information contained in FDA risk communications.

Developing and Initiating Validation of a Model Opioid Patient-Prescriber Agreement as a Tool for Patient-Centered Pain Treatment.

BACKGROUND: Opioid treatment agreements generally are used in pain treatment to delineate the terms and consequences of opioid use and abuse. METHODS: The US Food and Drug Administration (FDA) Safe Use Initiative convened a multi-disciplinary working group with outside experts to draft a patient-centered, model opioid treatment agreement named the Model Patient-Prescriber Agreement (model PPA). The model PPA was evaluated for readability and usability in two tests that sampled both healthcare professional and non-healthcare professional FDA employees. In a survey sent to FDA employees in the Center for Drug Evaluation and Research (CDER), 209 respondents assessed the quality of the content and the level of difficulty in reading and understanding the model PPA. Ten other FDA employees participated in usability testing to assess the effectiveness of the model PPA as an educational and decision-making tool. RESULTS: The majority of the 209 CDER employee survey respondents indicated the model PPA was neutral in tone (67.5%) and easy or somewhat easy to understand (90.4%). Usability study participants generally thought the model PPA would facilitate discussion between patient and prescriber and that the content was informative, thorough, and clear. CONCLUSIONS: These studies suggest that the working group was able to develop an opioid PPA that may be acceptable and usable among a diverse population of stakeholders. A follow-up pilot study using the model PPA in medical facilities in the USA with patients is underway and will facilitate this determination.
