Evidence of the economic benefit of clinical pharmacy services: 1996-2000.

We sought to summarize and assess original evaluations of the economic impact of clinical pharmacy services published from 1996–2000, and to provide recommendations and methodologic considerations for future research. A systematic literature search was conducted to identify articles that were then blinded and randomly assigned to reviewers who confirmed inclusion and abstracted key information. Results were compared with those of a similar review of literature published from 1988–1995. In the 59 included articles, the studies were conducted across a variety of practice sites that consisted of hospitals (52%), community pharmacies and clinics (41%), health maintenance organizations (3%), and long‐term or intermediate care facilities (3%). They focused on a broad range of clinical pharmacy services such as general pharmacotherapeutic monitoring (47%), target drug programs (20%), disease management programs (10%), and patient education or cognitive services (10%). Compared with the studies of the previous review, a greater proportion of evaluations were conducted in community pharmacies or clinics, and the types of services evaluated tended to be more comprehensive rather than specialized. Articles were categorized by type of evaluation: 36% were considered outcome analyses, 24% full economic analyses, 17% outcome descriptions, 15% cost and outcome descriptions, and 8% cost analyses. Compared with the studies of the previous review, a greater proportion of studies in the current review used more rigorous study designs. Most studies reported positive financial benefits of the clinical pharmacy service evaluated. In 16 studies, a benefit:cost ratio was reported by the authors or was able to be calculated by the reviewers (these ranged from 1.7:1–17.0:1, median 4.68:1). The body of literature from this 5‐year period provides continued evidence of the economic benefit of clinical pharmacy services. Although the quality of study design has improved, whenever possible, future evaluations of this type should incorporate methodologies that will further enhance the strength of evidence of this literature and the conclusions that may be drawn from it.

Economic Evaluations of Clinical Pharmacy Services—1988–1995

The objectives of this effort were to summarize and critique original economic assessments of clinical pharmacy services published from 1988–1995, and to make recommendations for future work in this area. A literature search was conducted to identify articles that were then blinded and randomly assigned to reviewers to confirm inclusion, abstract information, and assess the quality of study design. The 104 articles fell into four main categories based on type of service described: disease state management (4%), general pharmacotherapeutic monitoring (36%), pharmacokinetic monitoring services (13%), and targeted drug programs (47%). Articles were categorized by type of evaluation; 35% were considered outcome analyses, 32% outcome descriptions, and 18% full economic analyses. A majority (89%) of the studies reviewed described positive financial benefits from the clinical services evaluated; however, many (68%) did not include the input costs of providing the clinical service as part of the evaluation. Studies that were well conducted were most likely to demonstrate positive results. Commonly, results were expressed as net savings or costs avoided for a given time period or per patient. Seven studies expressed results as a benefit:cost ratio (these ranged from 1.08:1 to 75.84:1, mean 16.70:1). Overall this body of literature contains a wealth of information pertinent to the value of the clinical practice of pharmacy. Future economic evaluations of clinical pharmacy services should incorporate sound study design and evaluate practice in alternative settings.

100 billion each year. It is one of the most prevalent illnesses in the elderly population, and with the aging of society, will become even more significant. Costs associated with AD include direct medical costs such as nursing home care, direct nonmedical costs such as in‐home day care, and indirect costs such as lost patient and caregiver productivity. Medical treatment may have economic benefits by slowing the rate of cognitive decline, delaying institutionalization, reducing caregiver hours, and improving quality of life. Pharmacoeconomic evaluations have shown positive results regarding the effect of drug therapy on nursing home placement, cognition, and caregiver time.

Projecting future drug expenditures—2012

OBJECTIVE To describe the development of guidelines for the treatment of acute decompensated heart failure (ADHF) in the emergency department/observation unit (ED-OU) setting for hospitals that are part of a group purchasing organization (GPO). DATA SOURCES A MEDLINE search (1966-March 2003) using the following search terms: cardiotonic agents; diuretic; dobutamine; heart failure, congestive; milrinone; natriuretic peptide, brain; nesiritide; nitroglycerin; vasodilator agents, was conducted. STUDY SELECTION AND DATA EXTRACTION Relevant articles in the English language were identified. All randomized studies and meta-analyses for each category of drugs were included. DATA SYNTHESIS A group consensus method was used to develop guidelines. An expert panel reviewed and revised the guidelines. The final guidelines were approved June 1, 2003, and are described here. They are organized based upon a patients symptomatology at the time the diagnosis of ADHF is made. Patients with evidence of volume overload require intravenous diuretics and/or intravenous vasodilators to alleviate the symptoms of ADHF. Patients with signs and symptoms of low cardiac output require inotropic support to manage their ADHF. A timeline for diagnosis, treatment, reassessment, and disposition is provided and encourages an early, aggressive approach to treating patients with ADHF. CONCLUSIONS Hospitalization for ADHF is common and costly. Consensus guidelines for the treatment of ADHF did not previously exist, resulting in inconsistent and inefficient treatment. Consequently, hospitals struggling with the treatment of ADHF may find these guidelines and the process by which they were developed useful.

Factors that Influence Prescribing Decisions

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

Prioritizing future research on off-label prescribing: Results of a quantitative evaluation

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.

Thalidomide-associated deep vein thrombosis and pulmonary embolism

BACKGROUND Strategies to control the quality and cost of medication use are largely dependent on the ability to alter selection of medications. Previous models of prescribing behavior have focused on physicians. In the hospital setting, clinical pharmacists and formulary committee members are also key players in drug therapy decision-making. Differences between physicians, formulary committee members, and clinical pharmacists have not been compared. Knowledge of these differences could have importance in predicting the effectiveness of strategies designed to influence drug use in this setting. OBJECTIVE To describe and compare the opinions of physicians, clinical pharmacists, and formulary committee members with respect to key factors that influence medication prescribing in community hospitals. METHODS Physicians, clinical pharmacists, and formulary committee members were solicited to participate. A trained interviewer administered a standardized questionnaire designed to elicit opinions of participants regarding the importance of factors thought to influence drug prescribing. Responses were described using descriptive statistics, and differences between the groups were determined by post hoc analysis. RESULTS A total of 150 individuals participated in the study. Safety, effectiveness, formulary status, and restrictions on prescribing were considered highly influential by all participants. Physicians rated the availability of drug samples and personal experience higher (more influential on prescribing) than clinical pharmacists and formulary committee members. Clinical pharmacists and formulary committee members rated the influence of recommendations by clinical pharmacists, prescribing guidelines, and cost or cost comparisons higher than physicians. Factors that were drug-related or that involved policy-related programs tended to be more influential than indirect factors. CONCLUSIONS Those who seek to implement programs to alter medication use should recognize and employ factors that are most influential in the decision-making process. Further, it may be important to consider differences that exist between key participants in the medication use process.

Clopidogrel-associated bleeding and related complications in patients undergoing coronary artery bypass grafting.

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
