Purpose: To report historical patterns of pharmaceutical expenditures, to identify factors that may influence future spending, and to predict growth in drug spending in 2024 in the United States, with a focus on the nonfederal hospital and clinic sectors., Methods: Historical patterns were assessed by examining data on drug purchases from manufacturers using the IQVIA National Sales Perspectives database. Factors that may influence drug spending in hospitals and clinics in 2024 were reviewed-including new drug approvals, patent expirations, and potential new policies or legislation. Focused analyses were conducted for biosimilars, cancer drugs, endocrine drugs, generics, and specialty drugs. For nonfederal hospitals, clinics, and overall (all sectors), estimates of growth of pharmaceutical expenditures in 2024 were based on a combination of quantitative analyses and expert opinion., Results: In 2023, overall pharmaceutical expenditures in the US grew 13.6% compared to 2022, for a total of $722.5 billion. Utilization (a 6.5% increase), new drugs (a 4.2% increase) and price (a 2.9% increase) drove this increase. Semaglutide was the top drug in 2023, followed by adalimumab and apixaban. Drug expenditures were $37.1 billion (a 1.1% decrease) and $135.7 billion (a 15.0% increase) in nonfederal hospitals and clinics, respectively. In clinics, increased utilization drove growth, with a small impact from price and new products. In nonfederal hospitals, a drop in utilization led the decrease in expenditures, with price and new drugs modestly contributing to growth in spending. Several new drugs that will influence spending are expected to be approved in 2024. Specialty, endocrine, and cancer drugs will continue to drive expenditures., Conclusion: For 2024, we expect overall prescription drug spending to rise by 10.0% to 12.0%, whereas in clinics and hospitals we anticipate an 11.0% to 13.0% increase and a 0% to 2.0% increase, respectively, compared to 2023. These national estimates of future pharmaceutical expenditure growth may not be representative of any health system because of the myriad of local factors that influence actual spending., (© American Society of Health-System Pharmacists 2024.

Purpose: To report historical patterns of pharmaceutical expenditures, to identify factors that may influence future spending, and to predict growth in drug spending in 2021 in the United States, with a focus on the nonfederal hospital and clinic sectors., Methods: Historical patterns were assessed by examining data on drug purchases from manufacturers using the IQVIA National Sales Perspectives database. Factors that may influence drug spending in hospitals and clinics in 2021 were reviewed-including new drug approvals, patent expirations, and potential new policies or legislation. Focused analyses were conducted for biosimilars, cancer drugs, generics, coronavirus disease 2019 (COVID-19) pandemic influence, and specialty drugs. For nonfederal hospitals, clinics, and overall (all sectors), estimates of growth of pharmaceutical expenditures in 2021 were based on a combination of quantitative analyses and expert opinion., Results: In 2020, overall pharmaceutical expenditures in the United States grew 4.9% compared to 2019, for a total of $535.3 billion. Utilization (a 2.9% increase) and new drugs (a 1.8% increase) drove this increase, with price changes having minimal influence (a 0.3% increase). Adalimumab was the top drug in 2020, followed by apixaban and insulin glargine. Drug expenditures were $35.3 billion (a 4.6% decrease) and $98.4 billion (an 8.1% increase) in nonfederal hospitals and clinics, respectively. In clinics, growth was driven by new products and increased utilization, whereas in hospitals the decrease in expenditures was driven by reduced utilization. Several new drugs that will influence spending are expected to be approved in 2021. Specialty and cancer drugs will continue to drive expenditures along with the evolution of the COVID-19 pandemic., Conclusion: For 2021, we expect overall prescription drug spending to rise by 4% to 6%, whereas in clinics and hospitals we anticipate increases of 7% to 9% and 3% to 5%, respectively, compared to 2020. These national estimates of future pharmaceutical expenditure growth may not be representative of any particular health system because of the myriad of local factors that influence actual spending., (© American Society of Health-System Pharmacists 2021.

Purpose: To report historical patterns of pharmaceutical expenditures, to identify factors that may influence future spending, and to predict growth in drug spending in 2020 in the United States, with a focus on the nonfederal hospital and clinic sectors., Methods: Historical patterns were assessed by examining data on drug purchases from manufacturers using the IQVIA National Sales Perspectives database. Factors that may influence drug spending in hospitals and clinics in 2020 were reviewed, including new drug approvals, patent expirations, and potential new policies or legislation. Focused analyses were conducted for specialty drugs, biosimilars, and diabetes medications. For nonfederal hospitals, clinics, and overall (all sectors), estimates of growth of pharmaceutical expenditures in 2020 were based on a combination of quantitative analyses and expert opinion., Results: In 2019, overall US pharmaceutical expenditures grew 5.4% compared to 2018, for a total of $507.9 billion. This increase was driven to similar degrees by prices, utilization, and new drugs. Adalimumab was the top drug in US expenditures in 2019, followed by apixaban and insulin glargine. Drug expenditures were $36.9 billion (a 1.5% increase from 2018) and $90.3 billion (an 11.8% increase from 2018) in nonfederal hospitals and clinics, respectively. In clinics, growth was driven by new products and increased utilization, whereas in hospitals growth was driven by new products and price increases. Several new drugs that will likely influence spending are expected to be approved in 2020. Specialty and cancer drugs will continue to drive expenditures., Conclusion: For 2020 we expect overall prescription drug spending to rise by 4.0% to 6.0%, whereas in clinics and hospitals we anticipate increases of 9.0% to 11.0% and 2.0% to 4.0%, respectively, compared to 2019. These national estimates of future pharmaceutical expenditure growth may not be representative of any particular health system because of the myriad of local factors that influence actual spending., (© American Society of Health-System Pharmacists 2020.

Purpose: Historical trends and factors likely to influence future pharmaceutical expenditures are discussed, and projections are made for drug spending in 2019 in nonfederal hospitals, clinics, and overall (all sectors)., Methods: Drug expenditure data through calendar year 2018 were obtained from the IQVIA National Sales Perspectives database and analyzed. New drug approvals, patent expirations, and other factors that may influence drug spending in hospitals and clinics in 2019 were also reviewed. Expenditure projections for 2019 for nonfederal hospitals, clinics, and overall (all sectors) were made through a combination of quantitative analyses and expert opinion., Results: U.S. prescription sales in calendar year 2018 totaled $476.2 billion, a 5.5% increase from 2017 spending. The top 3 drugs by expenditures were adalimumab ($19.1 billion), insulin glargine ($9.3 billion), and etanercept ($8.0 billion). Prescription expenditures in nonfederal hospitals totaled $35.8 billion, a 4.8% increase from 2017. Expenditures in clinics in 2018 increased by 13.0% to $80.5 billion. The increase in spending in nonfederal hospitals was largely driven by new products and increased utilization of existing products. The list of the top 25 drugs by expenditures in nonfederal hospitals and clinics was dominated by specialty drugs., Conclusion: We predict continued moderate growth of 4-6% in overall drug expenditures (across the entire U.S. market). We expect the clinic sector to continue to experience high (11-13%) growth in drug spending in 2019. Finally, for nonfederal hospitals we anticipate growth in the range of 3-5%. These estimates are at the national level. Health-system pharmacy leaders should carefully examine local drug utilization patterns to determine their own organization's anticipated spending in 2019., (© American Society of Health-System Pharmacists 2019.

Purpose: Historical trends and factors likely to influence future pharmaceutical expenditures are discussed, and projections are made for drug spending in 2017 in nonfederal hospitals, clinics, and overall (all sectors)., Methods: Drug expenditure data through calendar year 2016 were obtained from the QuintilesIMS National Sales Perspectives database and analyzed. Other factors that may influence drug spending in hospitals and clinics in 2017, including new drug approvals and patent expirations, were also reviewed. Expenditure projections for 2017 for nonfederal hospitals, clinics, and overall (all sectors) were made based on a combination of quantitative analyses and expert opinion., Results: Total U.S. prescription sales in the 2016 calendar year were $448.2 billion, a 5.8% increase compared with 2015. More than half of the increase resulted from price hikes of existing drugs. Adalimumab was the top drug overall in 2016 expenditures ($13.6 billion); in clinics and nonfederal hospitals, infliximab was the top drug. Prescription expenditures in clinics and nonfederal hospitals totaled $63.7 billion (an 11.9% increase from 2015) and $34.5 billion (a 3.3% increase from 2015), respectively. In nonfederal hospitals and clinics, growth in spending was driven primarily by price increases of existing drugs and increased volume, respectively., Conclusion: We project a 6.0-8.0% increase in total drug expenditures across all settings, an 11.0-13.0% increase in clinics, and a 3.0-5.0% increase in hospital drug spending in 2017. Health-system pharmacy leaders should carefully examine their own local drug utilization patterns to determine their own organization's anticipated spending in 2017., Competing Interests: DisclosuresDr. Schumock has consulted for or received research funding from AbbVie, Astellas, and Baxter in the past 3 years.

Purpose: Overall and specific class trends in systemic antifungal expenditures in various U.S. healthcare settings from 2005 through 2015 were evaluated., Methods: Systemic antifungal expenditures from January 1, 2005, through December 31, 2015, were obtained from the QuintilesIMS National Sales Perspective database, which provides a statistically valid projection of medication purchases from multiple markets throughout the United States. Summary data for total antifungal expenditures over the entire period are reported, as are growth and the percentage change in expenditures from one year to the next. Expenditures were also assessed specifically by year, class, and healthcare setting. Expenditure trends over the study period were assessed using simple linear trend regression models., Results: Overall expenditures for the 11-year period were $9.37 billion. The greatest proportion of expenditures occurred in nonfederal hospitals (47.2%) and for triazoles (57.6%). From 2005 through 2015, total expenditures decreased from $1.1 billion to $894 million (-18.8%, p = 0.09); however, expenditures in clinics and retail pharmacies increased (202%, p < 0.01, and 13.8%, p = 0.04, respectively), a trend most pronounced after 2012. Expenditures for flucytosine also increased (968.1%, p < 0.01), particularly in clinics where there was a dramatic 6,640.9% increase ( p < 0.01)., Conclusion: From 2005 through 2015, an increase in systemic antifungal expenditures was observed in community settings, despite an overall decrease in total antifungal expenditures in the United States. Large increases in flucytosine expenditures were observed, particularly in the community., Competing Interests: DisclosuresThis work was supported by the Department of Veterans Affairs, Veterans Health Administration, Office of Research and Development, Health Services Research and Development Service Postdoctoral Fellowship Award (grant number TPR 42-005), awarded to Dr. Fitzpatrick.

Study Objective: New hepatitis C virus (HCV) antivirals have been shown to be highly effective with minimal adverse effects, but they are costly. Little is known, however, about the impact of the new HCV antivirals on expenditures in the overall U.S. health care system or by health care sector. Thus the objective of this study was to describe HCV antiviral expenditures by agent, year, and health care sector., Design: Retrospective cross-sectional study., Data Source: QuintilesIMS National Sales Perspectives database., Measurements and Main Results: QuintilesIMS National Sales Perspectives data for the period of January 1, 2009, to December 31, 2015, were used to describe HCV antiviral expenditures. HCV antiviral expenditures grew each year from $78 million in 2009 to $18 billion in 2015, except during 2013 when spending on HCV drugs dropped by $684 million (41%) compared with 2012. Although most expenditures in 2009 and 2010 were for interferons, this shifted to telaprevir in 2011-2013 and sofosbuvir-containing regimens in 2014-2015. Mail service and community pharmacies were associated with most of the expenditures throughout the study period., Conclusion: New HCV antivirals are driving the increased expenditures for this class. Decreased expenditures in 2013 may have been secondary to delaying HCV treatment until new therapies received approval from the U.S. Food and Drug Administration (termed "warehousing"). With continued drug development and approval of HCV therapies, expenditures are expected to continue to increase, barring actions by payers that may impede this trend. Medication policies guiding HCV treatment should focus on safety and efficacy while balancing the long-term costs of HCV., (© 2016 Pharmacotherapy Publications, Inc.)

Purpose: Historical trends and factors likely to influence future pharmaceutical expenditures are discussed, and projections are made for drug spending in 2016 in nonfederal hospitals, clinics, and overall (all sectors)., Methods: Drug expenditure data through calendar year 2015 were obtained from the IMS Health National Sales Perspectives database and analyzed. Other factors that may influence drug spending in hospitals and clinics in 2016, including new drug approvals and patent expirations, were also reviewed. Expenditure projections for 2016 were based on a combination of quantitative analyses and expert opinion., Results: Total U.S. prescription sales in the 2015 calendar year were $419.4 billion, which was 11.7% higher than sales in 2014. Prescription expenditures in clinics and nonfederal hospitals totaled $56.7 billion (a 15.9% increase) and $33.6 billion (a 10.7% increase), respectively, in 2015. In nonfederal hospitals, growth in spending was driven primarily by increased prices for existing drugs. The hepatitis C combination drug ledipasvir-sofosbuvir was the top drug overall in terms of 2015 expenditures ($14.3 billion); in both clinics and nonfederal hospitals, infliximab was the top drug. Individual drugs with the greatest increases in expenditures in 2015 were specialty agents and older generics; these agents are likely to continue to influence total spending in 2016., Conclusion: We project an 11-13% increase in total drug expenditures overall in 2016, with a 15-17% increase in clinic spending and a 10-12% increase in hospital spending. Health-system pharmacy leaders should carefully examine local drug utilization patterns in projecting their own organization's drug spending in 2016., (Copyright © 2016 by the American Society of Health-System Pharmacists, Inc.

Study Objectives: The clinical efficacy and cost-effectiveness of influenza antiviral use are controversial, with recent analyses suggesting potentially limited value. Thus, the objectives of this study were to describe influenza antiviral expenditures overall and by health care setting over a 10-year period (2003-2012) and to assess the correlation between outpatient influenza antiviral prescription use and influenza-like illness (ILI) outpatient visits., Design: Retrospective, cross-sectional study., Data Sources: IMS Health National Sales Perspectives and Xponent databases and Centers for Disease Control and Prevention ILINet national influenza surveillance system database., Patients: All prescriptions for oseltamivir, rimantadine, or zanamivir from community pharmacies, mail order pharmacies, clinics, nonfederal hospitals, and other health care settings (federal hospitals, military facilities, jails and prisons, universities, staff-model health maintenance organizations, veterinary hospitals and clinics, and long-term care facilities) between January 1, 2003, and December 31, 2012., Measurements and Main Results: Prescribing rates were calculated (prescriptions/1000 persons) for each year from 2003 to 2012 by using U.S. Census Bureau data. Influenza season was defined as July 1-June 30 of each calendar year. Linear regression assessed the correlation between influenza antiviral expenditures, prescription use, and ILI diagnoses. From 2003 to 2012, influenza antiviral drug expenditures accounted for $3.74 billion, with the majority from community pharmacies. After adjusting for inflation, no growth was observed for expenditures. A total of 32.8 million influenza antiviral prescriptions were dispensed from community pharmacies during the study period, and these prescriptions experienced 133.2% growth from 2003 to 2012. One third of expenditures and one quarter of dispensed prescriptions were in 2009. Influenza seasons were correlated with ILI and antiviral prescriptions. Annual community pharmacy expenditures were also associated with influenza antiviral prescriptions dispensed over the 10-year period., Conclusion: Influenza antivirals totaled $3.74 billion in the United States from 2003 to 2012, with the majority in 2009 and from community pharmacies. Influenza antivirals constituted a small proportion of total medication expenditures, but unforeseen pandemics resulted in unusually high use and expenditures. Influenza antiviral prescriptions dispensed from community pharmacies were associated with ILI and drug expenditures., (© 2015 Pharmacotherapy Publications, Inc.)

Purpose: An analysis of trends in U.S. pharmaceutical spending is presented, including projections for drug expenditures in nonfederal hospital and clinic settings in 2015., Methods: Prescription drug expenditure data through September 2014 were obtained from the IMS Health National Sales Perspectives database and were analyzed descriptively. Other factors that may influence prescription spending in hospitals and clinics in 2015, including new drug approvals and patent expirations, were analyzed. Expenditure projections were based on a combination of quantitative and qualitative analyses and expert opinion., Results: Total prescription sales for the 12 months ending September 30, 2014, were $360.7 billion, 12.2% higher than during the previous 12 months. With $6.6 billion in expenditures in the first 9 months of 2014, sofosbuvir topped the overall list of drugs based on sales, followed by aripiprazole and insulin glargine. Pharmaceutical spending by clinics and nonfederal hospitals rose by 13.3% and 4.0%, respectively. For the first 9 months of 2014, the top drugs based on expenditures were infliximab, pegfilgrastim, and epoetin alfa in clinics and infliximab, rituximab, and pegfilgrastim in hospitals. Specialty drugs continued to constitute an increasing portion of drug expenditures and will contribute to higher expenditures in 2015., Conclusion: Growth in U.S. prescription drug expenditures is expected to continue to increase in 2015. The projected increases in total drug expenditures are 7-9% across all settings, 12-14% in clinics, and 5-7% in hospitals. Health-system pharmacy leaders should carefully examine their own local drug utilization patterns to determine their own organization's anticipated spending in 2015., (Copyright © 2015 by the American Society of Health-System Pharmacists, Inc.

Objective: The objective of this analysis was to compare costs of paricalcitol or cinacalcet plus low dose vitamin D, and of phosphate binders, in patients in the IMPACT SHPT study; and to extrapolate those to estimate expected annual maintenance costs., Methods: IMPACT SHPT was a 28-week, randomized, open-label trial. Subjects from 12 countries received intravenous (IV) or oral paricalcitol, or oral cinacalcet plus fixed IV doxercalciferol or oral alfacalcidol. The primary end-point was the proportion of subjects who achieved a mean intact parathyroid hormone (iPTH) value of 150-300 pg/mL during weeks 21-28 (evaluation period). This study compares the costs of study drugs and phosphate binders among participants during the study and annualized. This analysis includes only those subjects that reached the evaluation period (134 in each group)., Results: The mean total drug costs over the study period were €2606 (SD = €2000) in the paricalcitol group and €3034 (SD = €3006) in the cinacalcet group (difference €428, p = 0.1712). The estimated annualized costs were €5387 (SD = €4139) in the paricalcitol group and €6870 (SD = €6256) in the cinacalcet group (difference €1492, p = 0.0395). In addition, a significantly greater proportion (p = 0.010) of subjects in the paricalcitol arm (56.0%) achieved an iPTH of 150-300 pg/mL during the evaluation period compared to the cinacalcet arm (38.2%)., Limitations: This was a secondary analysis of the IMPACT SHPT study which was not designed or powered for costs as an outcome. The dosing of study drugs and phosphate binders in the IMPACT study may not reflect actual practice, and patients were followed for 28 weeks, while the treatment of SHPT is long-term., Conclusion: Patients with SHPT requiring hemodialysis who were treated with a paricalcitol-based regimen for iPTH control had lower estimated annual drug costs compared to those treated with cinacalcet plus low-dose vitamin D.

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.

Purpose: Factors likely to influence drug expenditures, drug expenditure trends in 2010 and 2011, and projected drug expenditures for 2012 are discussed., Summary: Data were analyzed to provide drug expenditure trends for total drug expenditures and the hospital and clinic sectors. Data were obtained from the IMS Health National Sales Perspectives database. From 2009 to 2010, total U.S. drug expenditures increased by 2.7%, with total spending rising from $299.2 billion to $307.5 billion. Drug expenditures in clinics grew by 6.0% from 2009 to 2010. Hospital drug expenditures increased at the moderate rate of 1.5% from 2009 to 2010; through the first nine months of 2011, hospital drug expenditures increased by only 0.3% compared with the same period in 2010. The dominant trend over the past several years is substantial moderation in expenditure growth for widely used drugs, primarily due to the ongoing introduction and wide use of generic versions of high-cost, frequently used medications. At the end of 2010, generic drugs accounted for 78% of all retail prescriptions dispensed. Another pattern is substantial increases in expenditures for specialized medications, particularly in the outpatient setting as growth in prescription drug expenditures for clinic-administered drugs consistently outpaces growth in total expenditures. Various factors are likely to influence drug expenditures in 2012, including drugs in development, the diffusion of new drugs, generic drugs, drug shortages, and biosimilars., Conclusion: For 2012, we project a 3-5% increase in total drug expenditures across all settings, a 5-7% increase in expenditures for clinic-administered drugs, and a 0-2% increase in hospital drug expenditures.

PURPOSE. Drug expenditure trends in 2009 and 2010, projected drug expenditures for 2011, and factors likely to influence drug expenditures are discussed. SUMMARY. Various factors are likely to influence drug expenditures in 2011, including drugs in development, the diffusion of new drugs, generic drugs, health care reform, and biosimilars. Two distinct patterns of drug expenditures continue to exist. The dominant trend over the past several years is substantial moderation in expenditure growth for widely used drugs, primarily due to the ongoing introduction of generic medications for high-cost, frequently used medications and the influence of the economic downturn. The second pattern is substantial increases in expenditures for specialized medications, particularly in the outpatient setting. The influence of health care reform, the economy, and the emergence of biosimilars will be important trends to follow over the next several years, but they are unlikely to have substantial impact on drug expenditures in 2011. From 2008 to 2009, total U.S. drug expenditures increased by 5.2%, with total spending rising from $284.8 billion to $299.5 billion. Growth in drug expenditures in clinics grew by 5.1% from 2008 to 2009. Hospital drug expenditures increased at the moderate rate of 2.8% from 2008 to 2009; through the first nine months of 2010, hospital drug expenditures increased by only 0.8% compared with the same period in 2009. CONCLUSION. For 2011, we project a 3-5% increase in drug expenditures in outpatient settings, a 4-6% increase in expenditures for clinic-administered drugs, and a 1-3% increase in hospital drug expenditures.

Purpose: Drug expenditure trends in 2008 and 2009, projected drug expenditures for 2010, and factors likely to influence drug expenditures are discussed., Summary: Various factors are likely to influence drug expenditures in 2010, including drugs in development, the diffusion of new drugs, generic drugs, health care reform, drug safety concerns, and comparative effectiveness research. The increasing availability of important generic drugs continues to moderate growth in drug expenditures. Health care reform initiatives, including the potential for biosimilars legislation, will influence drug expenditures in all settings. From 2007 to 2008, total U.S. drug expenditures increased by 1.8%, with total spending rising from $279.6 billion to $284.7 billion. Growth in drug expenditures in clinics declined to the lowest level in a decade, a 1.0% increase from 2007 to 2008. Hospital drug expenditures increased at a moderate rate of only 2.1% from 2007 to 2008; through the first nine months of 2009, hospital drug expenditures increased by 3.0% compared with the same period in 2008., Conclusion: In 2010, we project a 3-5% increase in drug expenditures in outpatient settings, a 6-8% increase in expenditures for clinic-administered drugs, and a 2-4% increase in hospital drug expenditures.

Purpose: Drug expenditure trends in 2007 and 2008, projected drug expenditures for 2009, and factors likely to influence drug expenditures are discussed., Summary: Various factors are likely to influence drug expenditures in 2009, 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 that the Medicare Part D benefit has influenced drug expenditures, but the ultimate impact of the benefit on drug expenditures remains unclear. From 2006 to 2007, total U.S. drug expenditures increased by 4.0%, with total spending rising from $276 billion to $287 billion. Drug expenditures in clinics continue to grow more rapidly than in other settings, with a 9.9% increase from 2006 to 2007. Hospital drug expenditures increased at a moderate rate of only 1.6% from 2006 to 2007; through the first nine months of 2008, hospital drug expenditures increased by only 2.8% compared with the same period in 2007., Conclusion: In 2009, we project a 0-2% increase in drug expenditures in outpatient settings, a 1-3% increase in expenditures for clinic-administered drugs, and a 1-3% increase in hospital drug expenditures.

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.

Objectives: To analyze, from a payer perspective, the net pharmaceutical and medical costs of prescribing divalproex sodium extended-release (DVPX-ER) versus valproic acid (VPA) in patients with bipolar disorder., Methods: The study used a decision analytic framework to compare the total costs associated with DVPX-ER relative to VPA in the treatment of bipolar disease. The decision model incorporated two primary outcomes: GI side effects and treatment success. Levels of health service utilization and probability values were obtained from an expert panel comprised of 15 psychiatrists. Unit costs were obtained from an academic medical center. Two-way sensitivity analysis and a Monte Carlo simulation were conducted to examine the stability of the results., Results: The average probability of GI side effects associated with VPA and DVPX-ER estimated by the expert panel was 0.36 and 0.10 respectively. The average probability of treatment success for VPA and DVPX-ER was estimated to be 0.45 and 0.58 respectively. In the base case analysis, the expected total cost per patient was $34 208.84 and $25 336.13 for VPA and DVPX-ER respectively, a difference (incremental cost) of -$8188.87. Probabilistic sensitivity analysis using Monte Carlo simulation indicated a negative incremental cost of using DVPX-ER relative to VPA in a majority (approximately 70%) of cases., Conclusions: The results from this decision analysis, based on probabilities of major events and associated utilization from an expert panel, suggest that divalproex sodium extended-release results in lower total costs than valproic acid in the treatment of bipolar disorder. Limitations of this study primarily involved the sources of data used in the model, including that derived from expert opinion.

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.

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.

With insurance, consumers generally do not have a financial incentive to reduce or contain prescription drug use. Drug spending can be controlled by: Understanding the sources of drug cost Improving use of drug formularies Using clinical pharmacists to improve prescribing behavior.

Background/aimsThe objective of this study was to examine health care costs and utilization and the risks of dialysis or mortality among diabetic predialysis chronic kidney disease (CKD) patients with and without secondary hyperparathyroidism (SHPT).MethodsThis retrospective, matched cohort study examined insurance claims from 703 adult diabetic predialysis CKD patients with and without SHPT during a 72-month follow-up period. Annualized estimates of health care service utilization, costs and disease progression to dialysis or death following index CKD diagnosis were compared.ResultsPreindex (baseline) characteristics were similar between the cohorts. Postindex numbers of prescription utilization, outpatient service utilization and hospitalizations were all higher (p < 0.0001) in diabetic CKD patients with SHPT compared to those without SPHT in both unadjusted and adjusted analyses even after multivariate adjustment for known confounders. The rate of progression to dialysis or death was higher for diabetic CKD patients with SHPT compared to those without SPHT. Those with SHPT were at higher risk of requiring dialysis treatment [hazard ratio (HR) = 6.7; 95% confidence interval (CI) = 4.3-10.6] and death (HR = 2.3; 95% CI = 1.1-4.9) compared to those without SHPT.ConclusionIn diabetic predialysis CKD patients, the presence of SHPT is associated with significantly greater health care resource utilization and costs, and a faster rate of disease progression.
