The subsidy of pharmaceuticals in Australia: processes and challenges.

The increasing costs of health care, including new technologies and pharmaceuticals, pose challenges for all countries both in the developed and the developing world. It is essential that the increased expenditure on pharmaceuticals represents value for money and is seen as an investment in health care rather than simply the purchase of the latest released agent. The system in Australia uses a cost-effectiveness approach to guide the decisions as to whether a new drug can be recommended for subsidy. The need for a greater understanding and transparency of the processes is essential in order for a well-informed public debate to occur about the challenges to the system and its sustainability. The relevant issues are discussed in this article to assist that debate.

Medicaid prescription drug access restrictions: exploring the effect on patient persistence with hypertension medications.

OBJECTIVE: To compare rates of discontinuation of prescription therapy for hypertension in Medicaid patients with and without medication access restrictions. STUDY DESIGN: Retrospective cohort study. METHODS: Prescription data were extracted from a pharmacy claims database in a large state that implemented a Medicaid preferred drug list (PDL), both before and after the PDL was implemented. Prescriptions filled between June 2000 and May 2003 were included. RESULTS: Medicaid patients taking prescription medications commonly used to treat hypertension were 39% (odds ratio = 1.39; 95% confidence interval, 1.21, 1.6) more likely to discontinue hypertension therapy after the restriction was implemented compared with Medicaid patients 1 year earlier when there were no restrictions. Patients were classified as "discontinued" if they had therapy available less than 50% of the time during the 12 months after implementation of the PDL. Before the PDL, 17% of patients receiving treatment with hypertension medication discontinued therapy. After the PDL, 21% of Medicaid patients taking hypertension medication discontinued therapy. After the PDL, Medicaid patients were significantly more likely to switch medications from a restricted to an unrestricted drug. Those patients also were less likely to have a restricted drug added to their therapy regimen. CONCLUSIONS: After implementation of the PDL, Medicaid patients were more likely to discontinue filling prescriptions for antihypertensive medication. Because hypertension management is an important challenge within the Medicaid community, the potential connection between access restrictions and patient adherence to medication therapy is a worthy topic for further exploratory studies and quantitative outcomes research.

Industry's perception of presenting pharmacoeconomic models to managed care organizations.

BACKGROUND: Previous research has shown that pharmacoeconomic (PE) data are considered important but may not be optimally utilized by decision makers. No research has compared the effectiveness of different types of PE models. OBJECTIVES: The purpose of this study was to examine the perceived value and understanding of PE models among decision makers in managed care organizations. The perspective of this study was from research scientists working in the pharmaceutical industry who present PE models to managed care clients. The study objectives were to (1) examine what types of models are best received by decision makers, (2) investigate the barriers to using PE models, and (3) recommend methods for improving PE models. METHODS: A telephone survey of 39 items was conducted with 20 PE research scientists from various U.S. pharmaceutical and biotechnology companies. Topics addressed included factors contributing to how well PE models are received, barriers to using PE models, and recommendations for improving PE models. RESULTS: Models have an impact on health policy decision making. Nineteen of 20 respondents had at least one experience where a PE model played a role in optimizing the formulary positioning of a product. No single model format (e.g., decision analytic tools, spreadsheet analyses, Markov models, multivariate regression models) was regarded as the most effective model type. Although 7 of 20 respondents said simple spreadsheet models were most effective, well-designed, scientifically sound regression models were also reported to be very effective. CONCLUSIONS: The respondents commonly used models to share PE information, which was said to play a role in making health policy decisions by decision makers in managed care. There was no consensus regarding the type of model that was most effective. Study participants indicated that a variety of model designs are effective, ranging from simple spreadsheet models to multivariate regression models. Recommendations for improving PE models include (1) producing scientifically sound models, (2) customizing models where possible, (3) making models transparent, (4) making models user friendly, and (5) involving a nonbiased third party for model development.

Impact of clinical trials on the adoption of new drugs within a university hospital.

To assess the influence that clinical trials may have on the introduction of new drugs into prescribing routines, the adoption of drugs has been studied in a university hospital in the Netherlands. A significant relation was found between the testing of semi-innovative drugs in clinical trials in the hospital and the introduction of these drugs into general use in the same hospital. No such relationship was found for innovative drugs. Employment in clinical trials only affected the frequency of adoption of semi-innovative drugs. It did not influence the quantity of their use once they had been adopted. The idea that the stimulating effect of clinical trials on the adoption of semi-innovative drugs is only due to acceleration of the adoption process was not confirmed. These findings support the idea that clinical trials can lower the barriers for adoption of semi-innovative drugs.
