Pharmaceutical industry gifts and payments to physicians increase inappropriate prescribing and the number of prescriptions written, according to a Cochrane review analyzing dozens of previous studies.
In Plain English: The Clinical Takeaway
- Gifts Influence Prescribing: Accepting gifts and payments from pharmaceutical companies increases inappropriate prescribing and the number of prescriptions written.
- Policy Works: Healthcare institutions that enforce conflict-of-interest policies that restrict or manage interactions between companies and doctors probably improve prescribing practices.
- Formulary Impact Unclear: Current data remains insufficient to draw clear conclusions on whether free drug samples and other promotions affect decisions to place specific drugs on hospital formularies.
Cochrane Review Links Industry Payments to Prescription Volume
The analysis examined the influence the pharmaceutical industry has on medical practice. According to the findings, gifts and payments from drug manufacturers increase inappropriate prescribing and the number of prescriptions written, likely leading to rising health care costs. This dynamic contributes to escalating overall healthcare expenditures.
Beyond direct gifts and payments, pharmaceutical advertising or education aimed at doctors also alters clinical behavior. The review indicates that such initiatives probably increase the number of prescriptions written and may increase the costs of prescriptions, while also likely increasing inappropriate prescribing.
Institutional Restrictions Improve Prescribing Practices
The analysis found that conflict-of-interest policies that restrict or manage interactions between companies and doctors probably improve prescribing practices.
Despite the link between general marketing and prescribing, the review identified a notable evidence gap regarding hospital formularies. The data currently lacks sufficient evidence to determine whether free drug samples and other promotions affect decisions to place specific drugs on hospital formularies, which are the list of medicines approved for use and routinely stocked in a hospital or health system.
