Direct-to-consumer television advertising: time to turn off the tube?

Trends and effects of pharmaceutical DTCA

Purpose

The purpose of this paper is to investigate the current trend of pharmaceutical direct-to-consumer advertising (DTCA) in the USA and its effect to patients, physicians and drug utilization. The DTCA of pharmaceutical firms is defined as an attempt of pharmaceutical companies to advertise product directly to patients.

Design/methodology/approach

The methodology used is literature review complemented with a semi-structured interview.

Findings

Pharmaceutical DTCA showed a reduction in total spending, whereas the online channel experienced growth. DTCA affected the physician–patient relationship and patient satisfaction. Patients who received medication associated with DTCA showed higher satisfaction. DTCA of second-line drugs resulted in an increase of first-line drug utilization. Benefits of pharmaceutical DTCA include enhancing appropriate drug utilization and increasing awareness. DTCA might cause harm by interfering with physician’s decisions regarding drug choice.

Research limitations/implications

Limitations include limited available information of DTCA spending from pharmaceutical companies and lack of quantitative data on the effect of pharmaceutical DTCA. In addition, DTCA is sometimes affected by research bias.

Practical implications

Improvement in the physician–patient relationship and patient satisfaction, as well as in the quality of care provided may be demonstrated.

Social implications

Pharmaceutical firms using DTCA marketing advertisement methodologies can increase awareness of underdiagnosed conditions and affect medication costs and the utilization of appropriate drug utilization.

Originality/value

Review highlights current relationships between DTCA, patients, physicians and drug utilization to explore the effects DTCA on consumers.

Awareness of the Food and Drug Administration's Bad Ad Program and Education Regarding Pharmaceutical Advertising: A National Survey of Prescribers in Ambulatory Care Settings

The U.S. Food and Drug Administration's Bad Ad program educates health care professionals about false or misleading advertising and marketing and provides a pathway to report suspect materials. To assess familiarity with this program and the extent of training about pharmaceutical marketing, a sample of 2,008 health care professionals, weighted to be nationally representative, responded to an online survey. Approximately equal numbers of primary care physicians, specialists, physician assistants, and nurse practitioners answered questions concerning Bad Ad program awareness and its usefulness, as well as their likelihood of reporting false or misleading advertising, confidence in identifying such advertising, and training about pharmaceutical marketing. Results showed that fewer than a quarter reported any awareness of the Bad Ad program. Nonetheless, a substantial percentage (43%) thought it seemed useful and 50% reported being at least somewhat likely to report false or misleading advertising in the future. Nurse practitioners and physician assistants expressed more openness to the program and reported receiving more training about pharmaceutical marketing. Bad Ad program awareness is low, but opportunity exists to solicit assistance from health care professionals and to help health care professionals recognize false and misleading advertising. Nurse practitioners and physician assistants are perhaps the most likely contributors to the program.

The rise of digital direct-to-consumer advertising?: Comparison of direct-to-consumer advertising expenditure trends from publicly available data sources and global policy implications

Background

Pharmaceutical marketing is undergoing a major shift in the United States, in part due to new transparency regulations under the healthcare reform act. Changes in pharmaceutical marketing practices include a possible shift from more traditional forms of direct-to-consumer advertising towards emerging use of Internet-based DTCA (“eDTCA”) given the growing importance of digital health or “eHealth.” Though legally allowed only in the U.S. and New Zealand, eDTCA poses novel regulatory challenges, as it can cross geopolitical boundaries and impact health systems and populations outside of these countries.

Methods

We wished to assess whether changes in DTCA and eDTCA expenditure trends was occurring using publicly available pharmaceutical marketing data. DTCA data was analyzed to compare trends in aggregate marketing expenditures and to assess if there were statistically significant differences in trends and magnitudes for data sources and DTCA sub-categories (including eDTCA). This was accomplished using regression lines of DTCA trend data and conducting pairwise comparisons of regression coefficients using t-tests. Means testing was utilized for comparing magnitude of DTCA expenditure.

Results

Data from multiple data sources indicate that aggregate DTCA expenditures have slightly declined during the period from 2005–2009 and are consistent with results from other studies. For DTCA sub-categories, television remained the most utilized form of DTCA, though experienced trends of declining expenditures (−13.2 %) similar to other traditional media platforms such as radio (−30.7 %) and outdoor ads (−12.1 %). The only DTCA sub-category that experienced substantial increased expenditures was eDTCA (+109.0 %) and it was the only medium that had statistically significant differences in its marketing expenditure trends compared to other DTCA sub-categories.

Conclusions

Our study indicates that traditional DTCA marketing may be on the decline. Conversely, the only DTCA sub-category that experienced significant increases was eDTCA. However, to fully understand this possible shift to “digital” DTCA, improvements in publicly available DTCA data sources are necessary to confirm changing trends and validate existing data. Hence, utilizing the newly implemented U.S. physician-payment expenditure transparency requirements, we advocate for the mandatory disclosure of DTCA/eDTCA in order to inform future domestic and international health policy efforts regarding appropriate regulation of pharmaceutical promotion.

The effect of competing direct-to-consumer advertising campaigns on the use of drugs for benign prostatic hyperplasia: time series analysis

BACKGROUND

Direct-to-consumer advertising (DTCA) remains a controversial issue, with concerns that it leads to unnecessary and inappropriate prescribing. Whether DTCA shifts prescribing from first-line (guideline-recommended) therapy to second-line drugs has not been studied.

OBJECTIVE

The purpose of this study was to determine the impact of sequential DTCA campaigns for two drugs used to treat benign prostatic hyperplasia (BPH): one newer agent, dutasteride (Avodart(®)), and one older first-line agent, tamsulosin (Flomax(®)).

DESIGN

Interrupted time series analysis was used to assess the impact of each DTCA campaign using data on consumer "response" from Google Trends and dispensed prescriptions from IMS Health.

PARTICIPANTS

We analyzed data for the United States from January 2003 to December 2007.

INTERVENTION

DTCA for dutasteride and tamsulosin commenced on July, 2005 and April, 2006, respectively.

MAIN MEASURES

Monthly Internet search volume (scaled from 0 to 100) for the advertised trade name of each drug and monthly U.S. prescription rates per 1,000 population were analyzed.

KEY RESULTS

The dutasteride campaign was associated with an increase in Internet searches for both "Avodart" (level change +31.3 %, 95 % CI: 27.2-35.4) and "Flomax" (level change +8.3 %, 95 % CI: 0.9-15.7), whereas the tamsulosin campaign was associated with increased "Flomax" searches (level change +25.3 %, 95 % CI: 18.7-31.8). The dutasteride campaign was associated with an increase in the prescription of dutasteride (trend = 0.45/month, 95 % CI: 0.33-0.56), but a larger impact was observed with tamsulosin prescriptions (trend = 0.76/month, 95 % CI: 0.02-1.50). Similarly, the tamsulosin campaign was associated with an immediate fourfold increase in the prescribing of tamsulosin (level change +5.76 units, 95 % CI: 1.79-9.72) compared to dutasteride (level change +1.47 units, 95 % CI: 0.79-2.14).

CONCLUSIONS

DTCA was associated with the utilization of drugs to treat symptomatic BPH. However, both campaigns were associated with greater increases in the use of the guideline-recommended first-line agent. DTCA campaigns may increase the overall levels of guideline-recommended treatments to a greater extent than the specific advertised agents.
