A review of DTCA techniques: Appraising their success and potential impact on medication users

Building an effective medicines optimisation model: a health system approach

This commentary narrates on the building of an effective and innovative medicines optimisation model. It discusses the essential features, emphasizes the need, and considers the strong health and pharmacy system as a prerequisite before such a model could be built. The paper argues that it is important to strengthen the health system before the elements of pharmaceutical care and medicine optimisation can take shape. It discusses the discourse and interplay between medicine use and medicine access research. The other important elements to include are the "selection of medicines by health technology assessment", "economic evaluation of pharmacy services", "pharmacists' remuneration by the government", "Health system strengthening status", "quality use of generic medicines programmes", "rationale prescribing", "access to medicines and medicines pricing", "medicines advertising" and the "state of pharmacy practice and the development of the pharmacist's role". A set of different high-, middle- and low-income countries are used to provide examples of the status of the health system and the subsequent development of pharmacy practice and medicines optimisation. The countries include the UK, Australia, New Zealand, Pakistan, Türkiye, Malaysia, India, and Pakistan.

Fair Balance of Prescription Drug Information on Legitimate and Illegitimate Online Pharmacy Websites

Patients require important information when prescribed medications. For example, the U.S. Food and Drug Administration (FDA) requires that promotional information includes a fair balance of risks and benefits. This study evaluates how well legitimate online pharmacies (LOPs) and illegitimate online pharmacies (IOPs) comply with the spirit of the FDA's fair balance guidelines by examining the extent and equivalence of risk and benefit information on their websites. This study analyzed the content of 307 online pharmacy websites. Most (90.3%) communicated drug benefits, while 84.7% provided risks. Both risk and benefit information was moderately extensive. Presentation of risks and benefits differed between online pharmacy types. Compared to LOPs, IOPs were more likely to present risk information but also exaggerate benefits. Four in ten online pharmacies presented a fair balance of risks and benefits. However, LOPs (47.4%) were more likely to present a fair balance than IOPs (36.5%). Interestingly, IOPs were more likely to disclose instructions for use and overdose information than LOPs. These findings underscore the need for regulatory guidelines to encourage online pharmacies to present a fair balance of benefit and risk information. Also, pharmacists should develop online approaches to better fulfill their professional responsibility as drug information providers while maintaining their integrity and objectivity.

Implied Claims in Drug Advertising: A Review of Recent Literature and Regulatory Actions

Federal agencies and self-regulatory bodies help to ensure prescription and nonprescription drug promotion contains accurate information; however, false or misleading claims may cause people to have inaccurate perceptions of a drug and inhibit their ability to make informed decisions. We conducted a systematic review assessing evidence from 2012-2021 on how consumers and healthcare providers (HCPs) interpret claims made indirectly or through inference (implied or implicit claims) as well as synthesizing prescription and nonprescription drug advertising claims that have been the subject of regulatory actions from 2017-2021. Our search identified 16 studies from the peer-reviewed literature and 26 letters or case reports issued by the Food and Drug Administration (FDA) or National Advertising Division (NAD). Results from peer-reviewed studies suggest that implied claims can result in inferences that may not be warranted by the material facts about the drug. Perceptions of a drug's efficacy and, to a lesser extent, risk, are influenced by implied and explicitly false claims in prescription drug promotion. Claims related to implied superiority and overstatement of efficacy were the most prevalent claims flagged for review and examined in the literature. These types of claims were also the subject of many of the compliance actions by the FDA and case reports from the NAD. More research is needed to understand how people interpret varying types of implied claims and the impact of such claims on key outcomes. From a policy standpoint, understanding how people interpret implied claims can inform how the FDA approaches these claims in the marketplace.

Effects of conflicting prescription drug information from direct-to-consumer advertising and drug injury advertising on patients' beliefs and medication adherence

BACKGROUND

Patients are often exposed to contradictory information about pharmaceutical products from various types of advertising. For example, direct-to-consumer advertising (DTCA) tend to emphasize a drug's benefits, while drug injury advertising emphasizes the worst side effects. Regarding DTCA as a drug information source, many researchers in pharmacy field focus on investigating the misinformation in DTCA and corrective advertising. However, no prior research has examined the effects of such contradictory advertising messages on patients' prescription medicine-related beliefs and medication adherence. This is a significant gap in the research literature on pharmaceutical advertising effects and medication adherence.

OBJECTIVE

This is aimed to examine how exposure to DTCA and drug injury advertising would influence patients' chronic accessibility of drug-related beliefs and their medication adherence behavior.

METHODS

An online survey was conducted with a sample of 213 patients taking prescription blood thinners.

RESULTS

The findings from this study did not support the predicted relationship between exposure to DTCA and consumers' drug-related belief accessibility or their medication adherence. However, this study found a significant interaction effect of exposure to DTCA and exposure to drug injury ads on patients' medication adherence. The analysis results demonstrate that, for those who were exposed to drug injury ads, a significant negative relationship emerged between DTCA exposure and medication adherence.

CONCLUSION

This study provides important empirical evidence of a negative interaction effect of exposure to DTCA and drug injury ads on patients' medication adherence, which demonstrates that the influence of DTCA and drug injury ad exposures on patients' medication adherence is not independent, separate process but an interactive process. A communication campaign with corrective advertising could alleviate the negative interaction effect of exposure to contradictory information from different types of pharmaceutical ads on patients' medication adherence.

Development and validation of prescription drug risk, efficacy, and benefit perception measures in the context of direct-to-consumer prescription drug advertising

PURPOSE

Understanding patient perceptions of prescription drug risks and benefits is an important component of determining risk-benefit tradeoffs and helping patients make informed medication decisions. However, few validated measures exist for capturing such perceptions. The purpose of this study was to develop and validate measures of perception of prescription drug risk, efficacy, and benefit.

METHODS

We conducted a mixed-methods study to develop and validate the measures, including three waves of quantitative testing (item nonresponse, criterion-related validity, and convergent validity). We conducted quantitative testing with a probability-based online consumer panel of U.S. adults (n = 7635), eliminating weaker items after each testing wave.

RESULTS

Upon completion of all testing, we identified 21 validated measures that represent 11 distinct risk/benefit constructs. The final measures demonstrated face validity, convergent validity, criterion-related validity, and scale reliability in both illness and general population samples, among patients with both symptomatic and asymptomatic health conditions, and in response to both television and print direct-to-consumer prescription drug advertisements.

CONCLUSIONS

Our study produced a set of items that researchers and practitioners can use to assess patient perceptions of prescription drug risk, benefit, and efficacy and to ensure greater future comparability between studies.

Electronic direct-to-consumer advertising of pharmaceuticals: an assessment of textual and visual content of websites

Considering the important role of the Internet in health information seeking by consumers, it is critical to examine the health information that is available to them through the Internet. This study contributes to existing knowledge by employing a content analysis to examine visual and textual information on prescription medication websites. A stratified random sample was selected from a list of the 100 most-prescribed medications in the United States. Findings point to under-utilization of audiovisual components on the homepage of prescription medication websites as well as a lack of racial diversity in people pictured. Medications for chronic conditions were more likely to have homepages with a positive emotional tone than those for acute conditions. Further, more depictions of women on homepages predicted a greater number of prescriptions filled. This study includes implications for health education and healthcare professionals, patients and the Food and Drug Administration.

The Presence and Persistence of Unrealistic Expectations in Patients Undergoing Nerve Surgery

BACKGROUND

Unrealistic expectations of the outcomes of peripheral nerve surgery reduce patient satisfaction. Most clinicians can recall patients with unrealistic expectations despite verbal preoperative education.

OBJECTIVE

To assess patients’ baseline level of understanding regarding nerve surgery and appropriate expectations. Additionally, we tested the effect of a written, preoperative educational handout on the patients’ retention of knowledge.

METHODS

This cross-sectional survey recruited patients scheduled to undergo peripheral nerve surgery at a single institution in 2016 to 2017. During the preoperative visit, a specialized nurse practitioner reviewed perioperative protocols, risks and benefits of the surgery, and postoperative care. Patients immediately completed a survey to assess their preoperative understanding of the verbally reviewed information. During the same visit, an additional written handout was given to patients in a randomized fashion. At their first postoperative visit, all patients completed the survey again.

RESULTS

A total of 60 patients (mean age 52 yr) were enrolled of which 62% were male. Immediately following verbal instruction, 31% of patients had erroneous (unrealistic) expectations regarding pain, 30% had erroneous expectations regarding postoperative motor outcome, and 41% had erroneous expectations regarding the timing of postoperative recovery. There was no significant difference between patients who received the written handout vs those who did not, on retesting in the postoperative period.

CONCLUSION

Patients undergoing peripheral nerve procedures demonstrated a high baseline level of unrealistic expectations despite standard in-person verbal counseling by specialty providers. A written handout did not have clear benefit in the retention of preoperative surgical teaching. Further investigation into more effective preoperative patient counseling is needed.
