Is the Cost of Prescription Pharmaceuticals Correlated with Medicinal Effectiveness?
Prescription pharmaceuticals often capture the attention of consumers and policymakers alike due to their significant role in healthcare. One common question that arises is whether the cost of these drugs is related to their effectiveness. To address this, we need to look beyond the number on the price tag and consider the complex factors that influence drug pricing.
Chambers' Study
Dr. James D. Chambers, a researcher at the Institute for Clinical Research and Health Policy Studies at Tufts Medical Center, examined drugs approved between 1999 and 2012. His findings revealed that one-third of newer drugs do not offer better efficacy than their older counterparts. In some cases, these newer drugs can even have worse outcomes due to increased side effects. This research brings to light the stark reality that drug effectiveness is not always tied to price or development costs.
No Direct Correlation
According to Dr. Chambers, the cost of a drug is not directly related to its effectiveness. Pharmaceutical companies often recover development costs and make a profit, even if the new drug is not significantly more effective. The pricing of drugs is influenced by a variety of factors:
The cost of research and development (RD). The cost of unsuccessful drug development. Marketing and management salaries. Advertising and promotional activities. Shareholder interests and potential gains from successful drugs.These elements can drive up the overall cost of a drug, making it less about the drug's efficacy and more about maximizing profitability.
Case Study: Abilify
To illustrate the point, let's delve into a specific case study of Abilify, an antipsychotic used primarily for schizophrenia. The pricing of Abilify is not based solely on its effectiveness in the general population but on its pharmacoeconomic benefit for a specific subgroup, namely individuals suffering from schizophrenia.
Schizophrenia is a chronic mental illness characterized by severe impairments in cognition and social functioning. The treatment of schizophrenia typically follows a pattern of episodic acute episodes, necessitating hospitalization, followed by maintenance treatment in a community setting. Given the challenges associated with managing schizophrenia, the cost of healthcare can be quite high:
A typical hospital stay for an acute psychotic episode is often capped at 29 days. Medicaid reimbursement for hospital stays is limited to 29 days, making these episodes extremely expensive for patients and healthcare providers. Long-term management of schizophrenia involves ongoing medical and behavioral health care, which can also be costly.Therefore, a drug like Abilify, which can help extend the interval between acute episodes and improve patient compliance, can justify a higher price by significantly reducing the overall cost of care. For instance, if Abilify helps in extending the interval between episodes and improving patient outcomes, the cost per day may be more justifiable.
Conclusion
While the cost of prescription pharmaceuticals is often a point of concern, it is important to understand that there is no direct correlation between the price of a drug and its effectiveness. The pricing is influenced by various factors, including RD costs, unsuccessful drug development, and the cost of marketing and management. For drugs like Abilify, which offer significant pharmacoeconomic benefits for specific patient populations, the higher cost can be justified by their ability to improve patient outcomes and reduce overall healthcare costs.
