Bad-Drug Ads or Killer Ads: The Effects of Drug Injury Advertising on Public Health
研究了针对制药公司的诉讼广告如何影响患者用药行为，发现这类广告导致抗凝药处方减少、住院增加，对公共健康产生负面影响。
This paper analyzes the impact of lawsuit advertisements targeting drug companies. Although the main purpose of the ads is to recruit potential lawsuit plaintiffs, they also reach a broad audience of viewers. Medical professionals have raised concerns that drug injury ads may lead uninjured patients to misperceive the risks and benefits of treatment, leading them to discontinue medically necessary drugs. The paper examines how drug injury ads affect prescription fills and subsequent health outcomes. The empirical context analyzes anticoagulants, which are commonly used by elderly patients to prevent strokes. The study finds that drug injury ads lead to a decrease in filled prescriptions for targeted drugs and a corresponding increase in hospitalizations for conditions treated with anticoagulants. These results point to meaningful public health consequences and highlight the benefits from policy responses that promote accurate and balanced information.
