Projecting future drug expenditures in U.S. nonfederal hospitals and clinics--2013.

PURPOSE Factors likely to influence drug expenditures, drug expenditure trends in 2012, and projected drug expenditures for U.S. nonfederal hospitals and clinics in 2013 are discussed. METHODS Prescription drug expenditure data for 2011 through September 2012 were obtained from the IMS Health National Sales Perspectives database. Expenditure projections were based on a combination of quantitative and qualitative analyses, combined with expert opinion. RESULTS Total prescription sales in the United States for the 12-month period ending September 2012 were $326.0 billion, a 0.8% increase from the previous 12 months. This rate of growth was the lowest in recent history and can be attributed to modest increases in expenditures for new products (3.3%) and the prices of existing products (5.9%), coupled with a marked decline in overall volume and mix (-8.4%). For the 9 months ending in September 2012, total prescription expenditures grew 2.7% when compared with the same period in 2011. Oncology products remained important expenditures for hospitals and clinics. Antineoplastic agents were the top medication class for expenditures in nonfederal hospitals, and oncology products accounted for 32.2% of drug expenditures in the clinic setting in the first 9 months of 2012. CONCLUSION For 2013, we project a 1-3% increase in total drug expenditures across all settings, a 2-4% increase in expenditures for clinic-administered drugs, and a 0.5% decline to 1.5% increase in hospital drug expenditures. Health-system pharmacy leaders should carefully examine their own local drug-utilization patterns to determine their own organization's drug expenditure forecast.
