Summary
This document discusses pharmacoeconomics, focusing on the economic evaluation of pharmaceuticals. It examines clinical problems addressed by pharmacoeconomic research, trends in the field, the drug development process, and case studies in high-dose chemotherapy and chronic heart failure. The document also touches upon methodological problems in research as well as the future of the field.

Results Patients undergoing transplantation used more resources, mostly due to inpatient care. High-dose chemotherapy plus stem-cell transplantation was associated with greater morbidity and economic costs, with no improvement in survival. preencoded.png Case Example 22.2: Multinational Economic Evaluation of Valsartan in Patients with Chronic Heart Failure Background Question Clinical investigators found no differences in What challenges are presented in a multinational mortality in a clinical trial of ACE inhibitor with the economic evaluation? addition of either valsartan or placebo for patients with heart failure. Results Mean cost of a hospitalization for heart failure was $423 less for patients in the valsartan group, compared to patients in the placebo group. Overall within-trial costs, including outpatient costs and the cost of valsartan, were $545 higher for patients in the valsartan group. preencoded.png Methodologic Problems to be Addressed by Pharmacoeconomic Research 1 Types of Analysis 2 Cost-Benefit 3 Cost-Effectiveness 4 Cost Identification preencoded.png Methodologic Issues in the Pharmacoeconomic Assessment of Therapies 1 Clinical Trials vs. Common Practice 2 Possible Solutions Issues in the Design of Prospective 3 Pharmacoeconomic Studies preencoded.png Issues in the Design of Prospective Pharmacoeconomic Studies 1 2 Sample Size Participation of Patients 3 4 Data Collection Multicenter Evaluations preencoded.png The Future As physicians are asked simultaneously to represent their patients' interests while being asked to deliver clinical services with parsimony, and as reimbursement for medical services becomes more centralized in the United States and other countries, decision makers must turn for assistance to collaborative efforts of epidemiologists and economists in the assessment of new therapeutic agents. preencoded.png
