Drug Company Gifts and Meals Were Linked to More — and Less Appropriate — Prescribing A Cochrane review of 93 studies covering millions of prescribers found industry payments and promotion consistently associated with more prescriptions, higher costs and less appropriate choices. | | | The Capital Brief | October 13 | | | Medicines & Patients Edition | | Drug Company Gifts and Meals Were Linked to More — and Less Appropriate — Prescribing | | | | When a doctor writes a prescription, patients assume the choice is based on evidence. A major review examined whether drug company marketing aimed at prescribers shapes those choices. Researchers led by the University of Sydney, with colleagues in Canada, the UK, Italy and the US, published an updated Cochrane systematic review on October 9. They analyzed 93 studies, 82 of them from the United States, examining gifts, payments, meals, free samples, sales visits and advertising aimed at prescribers. Most of the studies were observational, comparing prescribers with more or less contact with industry marketing. Only one was a randomized trial. Gifts and payments were associated with more prescriptions in 39 studies covering about 3.9 million prescribers, and with less appropriate prescribing in 10 studies covering about 2.9 million. They were probably associated with higher costs. Policies limiting conflicts of interest were probably associated with more appropriate prescribing. Because most studies were observational, the review cannot prove that marketing causes these changes. But the associations were consistent, and some showed a dose-response pattern, with more contact linked to larger effects. The useful idea is that even small gifts can influence decisions that feel purely professional. This edition explores the evidence, not advice about any medication. Questions about prescriptions belong with a clinician or pharmacist. | | 01 | What the review examined | | | Drug companies promote medicines to prescribers through sales visits, sponsored meals, payments, free samples and advertising. Cochrane reviews systematically gather and assess all available studies on a question. This review included studies searched through January 2025. It examined prescribing appropriateness, number of prescriptions, cost and requests to add drugs to hospital formularies. The studies were too different to combine into a single number, so results were summarized in words and charts. Evidence certainty was rated using a standard system called GRADE. The review received no funding. | | | | Gifts and payments, including meals, were the most studied form of marketing, in 62 studies. They were associated with more prescriptions of the promoted drugs. They were associated with less appropriate prescribing. They were probably associated with higher costs, with moderate certainty. According to the press release, the more company-paid meals doctors received, the more of that company's drug they prescribed. This pattern appeared across blood pressure drugs, cholesterol drugs, antidepressants and opioids. Even low-cost meals were associated with more opioid prescribing, according to the press release. | | 03 | Advertising, sales visits and samples | | | Advertising and industry-provided education probably increased the number of prescriptions, with moderate certainty. They may have increased inappropriate prescribing, though certainty was low. Evidence on free samples was very uncertain. Samples can help patients start medicines but may steer them toward newer, costlier drugs. Sales representatives often provide information that emphasizes benefits of specific products. Independent sources of drug information can offer a more balanced view. The review did not assess patient health outcomes directly. | | 04 | Policies that limit influence | | | Eight studies examined conflict-of-interest policies, such as limits on gifts or sales visits at academic medical centers. These policies were probably associated with more appropriate prescribing, with moderate certainty. They may have reduced the number of promoted-drug prescriptions. Their effect on costs was uncertain. In the US, the federal Open Payments program publicly reports industry payments to physicians. Professional ethics codes, including the American Medical Association's, address gifts from industry. The UK industry body says gifts are banned under its code. | | 05 | Why small gifts can matter | | | Research on human behavior shows that gifts can create a sense of obligation, even when unintended. Many doctors believe they are not influenced, while assuming colleagues might be. Repeated contact with a product can make it more familiar and top of mind. Lead author Barbara Mintzes said the more free meals doctors receive, the more likely they are to prescribe less appropriate or more expensive drugs. Co-author Lisa Bero said prescribing tends to become less appropriate, more frequent and more expensive. Dose-response patterns strengthen the case that the link is not coincidental. Still, observational data cannot rule out other explanations. | | | | Most included studies were observational, so the review cannot prove cause and effect. Only one randomized trial was included. Doctors who accept industry payments may differ in other ways from those who do not. Nearly 90% of studies came from the United States, limiting generalizability. Some details, including the meal and opioid findings, are from the press release rather than the full review. The review did not measure patient health outcomes. The authors called for research on the health effects of inappropriate prescribing. | | | | Ask your clinician why a particular medicine is recommended and whether alternatives exist. Ask whether a generic or lower-cost option would work as well. In the US, you can look up industry payments to your doctor in the CMS Open Payments database. Pharmacists can be a useful source of independent information about medicines. Bring a list of all your medications to appointments for review. Do not stop or change medications on your own based on these findings. Most doctors aim to do what is best for patients; questions support shared decision-making. | | 08 | The long view on trust in medicine | | | Prescribing decisions affect health, costs and trust in the medical system. This review suggests that industry marketing is consistently associated with more, costlier and sometimes less appropriate prescribing. For patients, practical questions include: Why this drug? Is there an older or cheaper option? What does the evidence say? For clinicians, independent education and transparency can protect professional judgment. For health systems, conflict-of-interest policies may help improve prescribing. The long-view idea is that good decisions depend on good information, free from hidden influence. Trust is built on transparency. | | | | The Takeaway | | 1 | A Cochrane review of 93 studies found drug company gifts and payments consistently associated with more prescriptions and less appropriate prescribing. | | 2 | Gifts and payments were probably associated with higher costs. | | 3 | Conflict-of-interest policies were probably associated with more appropriate prescribing. | | 4 | Most studies were observational and US-based, so causation cannot be proven. | | 5 | The findings support transparency and informed questions, not changing medications on your own. | | | Stay patient, stay curious,
