Pharmacists are key partners in antimicrobial stewardship efforts, yet their degree of education on and attitudes toward this topic during training are not well documented. An electronic survey measuring knowledge and attitudes regarding antimicrobial use and resistance was administered to graduating pharmacy students at 12 US schools of pharmacy. Of 1445 pharmacy students, 579 (40%) completed the survey. The vast majority (94%) believed that strong knowledge of antimicrobials was important for their pharmacy careers, and 89% desired more education on appropriate antimicrobial use. Most students (84%) considered their pharmacy education regarding antimicrobials useful or very useful, but there was significant variability on perceptions of preparation for most antimicrobial stewardship activities according to the students' school. The mean number of correct answers on a section of 11 knowledge questions was 5.8 (standard deviation 2.0; P value for score between schools <.001). On multivariable linear regression analysis, significant predictors of a higher knowledge score were pharmacy school attended, planned postgraduate training, completion of a clinical rotation in infectious diseases, perception of pharmacy school education as useful, use of resources to answer the knowledge questions, and use of Infectious Diseases Society of America guidelines and smartphone applications as frequent resources for learning about antimicrobials. Pharmacy students perceive antimicrobial stewardship to be an important healthcare issue and desire more education on the subject. Student perceptions of antimicrobial coursework and actual antimicrobial knowledge scores significantly varied by the school of pharmacy attended. Sharing of best practices among institutions may enhance the preparation of future pharmacists to contribute to effective antimicrobial stewardship.

Objective. The purpose of this study was to evaluate glycemic control as measured by A1C during a 2-year period after patients received diabetes self-management education (DSME). Methods. Patients who completed DSME in 2009 and received medical follow-up with A1C measurements for at least 2 years after DSME were included in the evaluation. Primary endpoints were changes in A1C from before to immediately after, 1 year after, and 2 years after DSME. Secondary outcomes included the effects of the following factors on change in A1C: sex, duration of diabetes, uncontrolled diabetes (A1C ≥ 9%), health insurance coverage, and self-reported education level. Results. Forty-three patients were included in the evaluation. Mean A1C before DSME was 10.2 ± 3.7%. Mean A1C after DSME was 7.8 ± 2.2% (P < 0.0001), a 23.5% reduction. Mean A1C at 1 and 2 years after DSME was 7.8 ± 2.1% for each year and remained unchanged from just after DSME to 1 and 2 years after DSME (P > 0.05). Patients with a duration of diabetes of < 1 year had a significantly greater reduction in mean A1C than those with a duration of diabetes ≥ 1 year (28.7 and 20.2%, respectively, P = 0.001). Conclusion. DSME improved glycemic control to a substantial degree, and the effect was sustained for up to 2 years. Although the reduction in A1C was significant for all patients receiving DSME, there was a significantly greater reduction for patients who had a duration of diabetes of < 1 year than for those with a duration of diabetes > 1 year.
CASE (DESCRIPTION): This report describes an incident of limb swelling after revaccination with the 23-valent pneumococcal polysaccharide vaccine (PPSV23). A 5-year old female with sickle cell disease experienced severe arm swelling with edema to the extent that it was difficult to put a shirt over the arm. The day prior, she received PPSV23 concomitantly with the meningococcal vaccine. She had received the PPSV23 vaccine 2.5 years prior to the event. The patient was managed with analgesics, antiemetics, and antibiotic prophylaxis and the arm swelling resolved 24 h later. A decreased length of time between revaccination and concurrent administration with the meningococcal vaccine could have contributed.
CONCLUSION: Although rare, limb swelling after revaccination could be a concern in special at-risk populations where repeated vaccination is necessary for pneumococcal protection.
PURPOSE: An analysis of trends in U.S. pharmaceutical spending is presented, including projections for drug expenditures in nonfederal hospital and clinic settings in 2014.
METHODS: Trends in pharmaceutical expenditures and developments likely to influence future spending, including new drug approvals and patent expirations, were analyzed using data from the IMS Health National Sales Perspectives database. Projections were based on a combination of quantitative and qualitative analyses and expert opinion.
RESULTS: Total prescription sales for the 12 months ending September 2013 were approximately $326 billion, 0.7% lower than sales during the previous 12 months; pharmaceutical spending by clinics and nonfederal hospitals grew by 4.5% and 1.8%, respectively. Vaccines were among the products driving large sales increases in clinic settings, with alteplase and pegfilgrastim topping the list of fast-growing drugs by hospital expenditures. Few new drug approvals anticipated in 2014 are expected to result in major expenditures by hospitals and clinics. Expansion of access to health care and other changes related to the Patient Protection and Affordable Care Act, as well as continued improvement in the U.S. economy, may drive growth in pharmaceutical spending over the next 12-24 months.
CONCLUSION: Growth in U.S. prescription drug expenditures is expected to rebound in 2014, with a projected 3-5% increase in total drug expenditures across all settings this year, including a 5-7% increase in clinic spending and a 1-3% increase in hospital spending. Health-system pharmacy leaders should carefully examine local drug-utilization patterns to determine their respective organization's anticipated spending in 2014.
OBJECTIVE To report an atypical case of Guillain-Barré syndrome (GBS) after administration of the 2012-13 influenza vaccine. SETTING Urban tertiary hospital. PATIENT DESCRIPTION An 81-year-old man was admitted to the hospital after he began experiencing numbness and tingling in both feet that began ascending toward the waistline. The patient complained of intense neuropathic pain in his lower extremities and eventually lost the deep tendon reflexes in his ankles. CASE SUMMARY In addition to clinical manifestations of GBS, electromyography revealed a sensorimotor, polyneuropathy, predominantly axonal, with prolonged F-waves in all nerves tested. A lumbar puncture revealed clear and colorless cerebrospinal fluid with an elevated protein level of 66 mg/dL (reference, 15-60 mg/dL) despite the lack of a normal cell count, which indicates albuminocytologic dissociation. Based on these findings, the patient met Brighton level 3 diagnostic certainty and was diagnosed with GBS. MAIN OUTCOMES MEASURE Signs and symptoms of GBS. RESULTS On day 5 of hospitalization, intravenous immunoglobulin 0.4 mg/kg/d was initiated for 5 days in combination with gabapentin 100 mg at bedtime for neuropathic pain. After completing treatment, the patient experienced progressively improved sensation in his extremities and was discharged. CONCLUSION This is a rare report of GBS lacking albuminocytologic dissociation after an older patient received the 2012-13 influenza vaccine.
The 2009 novel H1N1 influenza A virus (H1N1) became a global pandemic. Data on antiviral prescriptions by location from 2008 to 2010 have not been reported. The purpose of this study was to assess antiviral geographic trends and correlation with influenza-like illness (ILI) over 3 years. Percent of outpatient ILI visits and antiviral prescriptions from 1 January 2008 to 31 December 2010 were included. Linear regression was used to assess correlation. In total, 14 million antivirals were dispensed during this period. A 115% increase was observed in 2009 compared with prescriptions dispensed in 2008, and an 84% decrease was observed in 2010 compared with 2009. The rate of antivirals was 1.32 prescriptions/100 persons in 2008, 2.85/100 persons in 2009 and 0.435/100 persons in 2010. 2009 regional growth was observed in most states and was highest in the West (293%) and the Northeast (272%). A positive correlation was observed between antivirals and ILI visits (R(2)=0.7853; P<0.0001). With the 2009 H1N1 pandemic, antivirals increased compared with 2008 or 2010. Without the concern of H1N1, antivirals decreased in 2010 to levels lower than 2008. Geographic trends were also observed, which may be a result of the different intensity of influenza transmission and difference practice patterns. ILI diagnoses correlate with influenza antiviral prescription use in the USA.
Studies have consistently evidenced the positive clinical, economic, and humanistic benefits of pharmacist-directed patient care in a variety of settings. Given the vast differences in clinical outcomes associated with evaluated clinical pharmacy services (CPS), more detail as to the nature of the CPS is needed to better understand observed differences in economic outcomes. With the growing trend of outpatient pharmacy services, these economic evaluations serve as viable decision-making tools in choosing the most effective and cost-effective pharmacy programs. We previously conducted three systematic reviews to evaluate the economic impact of CPS from 1988 to 2005. In this systematic review, our objectives were to describe and evaluate the quality of economic evaluations of CPS published between 2006 and 2010, with the goal of informing administrators and practitioners as to their cost-effectiveness. We searched the scientific literature by using the Medline, International Pharmaceutical Abstracts, Embase, and Cumulative Index to Nursing and Allied Health Literature databases to identify studies describing CPS published from 2006 to 2010. Studies meeting our inclusion criteria (original research articles that evaluated CPS and described economic and clinical outcomes) were reviewed by two investigators. Methodology used, economic evaluation type, CPS setting and type, and clinical and economic outcome results were extracted. Results were informally compared with previous systematic reviews. Of 3587 potential studies identified, 25 met inclusion criteria. Common CPS settings were hospital (36%), community (32%), and clinic or hospital-based ambulatory practices (28%). CPS types were disease state management (48%), general pharmacotherapeutic monitoring (24%), target drug programs (8%), and patient education (4%). Two studies (8%) listed CPS as medication therapy management. Costs were evaluated in 24 studies (96%) and sufficiently described in 13 (52%). Clinical or humanistic outcomes were evaluated in 20 studies (80%) and were sufficiently described in 18 (72%). Control groups were included in 16 (70%) of 23 studies not involving modeling. Study assumptions and limitations were stated and justified in eight studies (32%). Conclusions and recommendations were considered justified and based on results in 24 studies (96%). Eighteen studies (72%) involved full economic evaluation. The mean ± SD study quality score for full economic evaluations (18 studies) was 60.4 ± 22.3 of a possible 100 points. Benefit-cost ratios from three studies ranged from 1.05:1 to 25.95:1, and incremental cost-effectiveness ratios of five studies were calculated and reported. Fewer studies documented the economic impact of CPS from 2006-2010 than from 2001-2005, although a higher proportion involved controlled designs and were full economic evaluations. Evaluations of ambulatory practices were increasingly common. CPS were generally considered cost-effective or provided a good benefit-cost ratio.
Meta-analyses are increasingly influencing clinical practice, but significant methodological flaws have been reported. The purpose of this study was to evaluate the quality of search strategies utilized by anti-infective meta-analyses. The Embase database was searched for meta-analyses evaluating anti-infective drug therapy; 103 of 268 identified citations met inclusion criteria and were evaluated. A total of 80.6% of meta-analyses used search terms, and an average of 4.3 databases (Medline, 98.1%; Cochrane, 93.2%; Embase, 76.7%) were searched to identify relevant articles for inclusion. The majority of meta-analyses used a quality assessment tool (84.5%) and reported positive results (59.2%). The average impact factor of journals publishing meta-analyses was 5.7 ± 3.4. The number of resources searched was associated with the impact factor ( P = .0013). The majority of anti-infective meta-analyses used rigorous search strategies to identify all relevant studies for evaluation. This finding is inconsistent with reports in other therapeutic areas that have questioned the quality of meta-analyses, and it may increase confidence in anti-infective meta-analyses.
Antibiotic-resistant bacteria are an increasing threat to the effectiveness of antibiotics. The majority of antibiotics are prescribed in primary care settings for upper respiratory tract infections. The purpose of this study was to describe seasonal trends in outpatient antibiotic prescriptions (Rx) in the United States over a 5-year period. This study was a retrospective, cross-sectional observation of systemic antibiotic prescriptions in the outpatient setting from 2006 to 2010. Winter months were defined as the first and fourth quarters of the calendar year. Antibiotic prescribing rates were calculated (prescriptions/1,000 population) using annual U.S. Census Bureau population data. Over 1.34 billion antibiotic prescriptions were dispensed over the 5-year period. The antibiotic prescription (Rx) rate decreased from 892 Rx/1,000 population in 2006 to 867 Rx/1,000 population in 2010. Penicillins and macrolides were the primary antibiotic classes prescribed, but penicillin prescribing decreased while macrolide prescribing increased over the study period. Overall, antibiotic prescriptions were 24.5% higher in winter months than in the summer, with the largest difference (28.8%) in 2008 and the smallest (20.4%) in 2010. This seasonality was consistently drug class dependent, driven by 75% and 100% increases in penicillin and macrolide prescriptions, respectively, in the winter months. The mean outpatient antibiotic prescription rate decreased in the United States from 2006 to 2010. More antibiotic prescribing, predominately driven by the macrolide and penicillin classes, in the outpatient setting was observed in the winter months. Understanding annual variability in antibiotic use can assist with designing interventions to improve the judicious use of antibiotics.
