Projecting future drug expenditures--2008.

PURPOSE: Drug expenditure trends in 2006 and 2007, projected drug expenditures by setting for 2008, and factors likely to influence drug expenditures are discussed. SUMMARY: Various factors are likely to influence drug expenditures in 2008, including drugs in development, the diffusion of new drugs, drug safety concerns, generic drugs, Medicare Part D, and changes in the drug supply chain. The increasing availability of important generic drugs and drug safety concerns continue to moderate growth in drug expenditures. The drug supply chain remains dynamic and may influence drug expenditures, particularly in specialized therapeutic areas. Initial data suggest the Medicare Part D benefit has influenced drug expenditures, but the ultimate impact of the benefit on drug expenditures remains unclear. From 2005 to 2006, total drug expenditures increased by 8.7% to $275 billion. Drug expenditures in clinics continue to grow more rapidly than in other settings, with a 20.9% increase from 2005 to 2006, and drug expenditures in clinics are now greater than the amount spent in hospitals. Hospital drug expenditures increased at a moderate rate of only 3.8% from 2005 to 2006; through the first nine months of 2007, hospital drug expenditures increased by only 2.2% compared with the same period in 2006. CONCLUSION: In 2008, we project a 5-7% increase in drug expenditures in outpatient settings, a 12-14% increase in clinics, and a 4-6% increase in hospitals.

Projecting future drug expenditures--2007.

PURPOSE: Drug expenditure trends in 2005 and 2006, projected drug expenditures for 2007, and factors likely to influence drug costs are discussed. SUMMARY: Various factors are likely to affect drug costs, including drug prices, drugs in development, and generic drugs. In 2005, there was a continued moderation of the increase in drug expenditures. Total prescription drug expenditures increased by 5.5% from 2004 to 2005, with total spending rising from $239 billion to $252 billion. Through the first nine months of 2006, hospital drug expenditures increased by only 3% compared with 2005. This moderation of the growth of prescription drug expenditures can be attributed to three major factors: availability of major prescription drugs in generic form, continued increase in cost sharing for employees in employer-sponsored health plans, and decreased use due to safety concerns. It is expected that expenditures in 2007 will be influenced by similar factors, with few costly new products reaching the market, increased concern over product safety reducing the use of older agents and slowing the diffusion of newer agents that do reach the market, and several important patent expirations, leading to slower growth in expenditures. CONCLUSION: In 2007, we project a 5-7% increase in drug expenditures in outpatient settings, a 14-16% increase in clinics, and a 4-6% increase in hospitals.

Projecting future drug expenditures--2006.

PURPOSE: Drug expenditure trends in 2004 and 2005, projected drug expenditures for 2006, and factors likely to influence drug costs are discussed. SUMMARY: Various factors are likely to affect drug costs, including drug prices, drugs in development, and generic drugs. In 2004 there was a continued moderation of the increase in drug expenditures. Drug expenditures increased by 8.7% from 2003 to 2004. Through the first nine months of 2005, expenditures increased by only 8.1% compared with 2004. This moderation can be attributed to several factors, including the continued trend toward higher prescription drug cost sharing for insured consumers, growing availability of generic drugs, and lack of "blockbuster" new drugs in recent years. Drug expenditures in 2006 will likely be influenced by similar factors, with few costly new products reaching the market, increased concern over product safety slowing the diffusion of those new agents that do reach the market, and several important patent expirations, leading to slower growth in expenditures. CONCLUSION: Forecasting and managing rising drug expenditures remains a challenge. Pharmacy managers must remain vigilant in monitoring drug costs in their health system and take a proactive role in pursuing efficient drug utilization. The dynamic health policy environment further complicates drug budgeting and must be considered, especially in integrated health systems responsible for managing inpatient, outpatient, and clinic drug costs. The comparison of health-system-specific data and trends with the national information presented in this article may provide a useful context when presenting institutional drug costs to senior management.

Projecting future drug expenditures--2005.

PURPOSE: Drug expenditure trends in 2003 and 2004 and projected drug expenditures for 2005 are discussed. SUMMARY: Various factors are likely to affect drug costs, including drug prices, drugs in development, and generic drugs. In 2003 there was a continued moderation of the increase in drug expenditures. Drug expenditures increased by 11.4% from 2002 to 2003. Through the first nine months of 2004, expenditures increased by only 8.7% compared with 2003. This moderation can be attributed to many factors, particularly patent expirations, prescription-to-nonprescription conversions and a continued slowdown in new drug approvals. Higher cost sharing for consumers and continued weaknesses in several sectors of the U.S. economy affecting employment levels and insurance coverage also contributed to this smaller increase in drug utilization. It is expected that 2005 drug expenditure growth will out-pace the growth in overall health care expenditures and growth in the economy. CONCLUSION: In 2005, there should be a 10-12% increase in drug expenditures in outpatient settings, a 12-15% increase in clinics, and a 6-9% increase in hospitals.

Projecting future drug expenditures--2004.

PURPOSE: Drug expenditure trends since 2002 and projected drug expenditures for 2004 are discussed. SUMMARY: In 2002 there was a moderation in the trend of increasing drug expenditures. Drug expenditures increased by 12.3% between 2001 and 2002. This trend continued in the first half of 2003, with expenditures increasing by only 10% compared with 2002. This moderation in the drug expenditures trend can be attributed to many factors, especially patent expirations and decreases in new drug approvals. Higher cost sharing for consumers and a general economic slowdown in the United States affecting employment and insurance coverage have resulted in a smaller increase in drug utilization. In 2004, there should be a 10-12% increase in drug expenditures for outpatient settings, a 19-21% increase for clinics, and a 6-8% increase for hospitals. CONCLUSION: Drug expenditure growth should continue to outpace the growth in overall health care expenditures and the growth in the U.S. economy.

Projecting future drug expenditures--2003.

Drug expenditure projections for 2003 and factors likely to influence drug costs are discussed. The United States continues to face the challenge of increased growth in health expenditures, and drug expenditures are continuing to increase faster than the growth in total health care expenditures. These increases can be largely attributed to an increase in the average age of the U.S. population and technological advancement. On the basis of price inflation and non-price inflationary factors, including increases in volume, shifts in patient and therapeutic intensity, and expected approval of new drugs, a 10-12% increase in drug expenditures in 2003 for the inpatient setting and a 13.5-15.5% increase for ambulatory care settings are forecasted. While few new drugs are expected to greatly influence expenditures in 2003, the continued diffusion of recently approved drugs such as drotrecogin alfa and nesiritide will have a dramatic impact on total drug expenditures and must be carefully considered in the budgeting process. An agent likely to have a significant impact on HIV treatment is enfuvirtide, the first in a new class of antiretrovirals (fusion inhibitors), but its high cost ($10,000-$15,000 per year) may limit patients' access to this medication. An expanded user's guide is provided to assist the reader in appropriate application of this information in the drug budgeting process. Technological, demographic, and market-based changes and changes in public policy will continue to influence pharmaceutical expenditures in the coming year. An understanding of the overall drivers of medication expenditures and vigilance in monitoring pharmaceutical innovation are critical in the effective management of these resources.
