Population characteristics associated with pharmacy-based influenza vaccination in United States survey data.

OBJECTIVES: To examine the population characteristics associated with the health behavior of receiving an influenza vaccine from a pharmacy-based setting. DESIGN: Secondary analysis of data from states that participated in an optional influenza module in the 2014 Behavioral Risk Factor Surveillance System, a state-based observational survey of U.S. adults. SETTING AND PARTICIPANTS: Analytic sample of 28,954 respondents from 8 states and Puerto Rico who reported receiving an influenza vaccination in the past year. MAIN OUTCOME MEASURES: The main outcome was a self-reported categoric variable indicating the setting of the most recent seasonal influenza vaccination: doctor's office, pharmacy-based store, or other setting. RESULTS: Multinomial logistic regression results showed that environmental, predisposing, enabling, and need factors in the Andersen model were salient features associated with odds of using pharmacy-based influenza vaccination settings instead of a doctor's office. Residents of states that allowed pharmacists as immunizers before 1999 reported greater use of pharmacy-based store settings (odds ratio [OR] 1.31). Compared with young adults, individuals 65 years of age and older were more likely to choose a pharmacy-based store than a doctor's office (OR 1.41) and less likely to use other community settings (OR 0.45). Compared with non-Hispanic whites, black respondents were less likely to use pharmacy-based store vaccination (OR 0.51), and multiracial and Hispanic respondents were more likely to use other settings (ORs 1.47 and 1.60, respectively). Enabling and need factors were also associated with setting. CONCLUSION: Based on this dataset of selected states from 2014, almost one-fourth of U.S. adults who reported receiving an annual influenza vaccination did so from a pharmacy-based store; 35% reported using other community-based settings that may enlist pharmacists as immunizers. There were striking disparities in use of nontraditional vaccination settings by age and race or ethnicity. Pharmacists and pharmacies should address missed opportunities for vaccination by targeting outreach efforts based on environmental and predisposing characteristics.

Diffusion of Pharmacy-Based Influenza Vaccination Over Time in the United States.

OBJECTIVES: To examine pharmacy-based influenza vaccination using diffusion of innovation theory. METHODS: We used 1993 to 2013 Behavioral Risk Factor Surveillance System data to generate weighted prevalence rates of influenza vaccination, stratified by age (18-64 years vs ≥ 65 years) and state of residence. The diffusion of innovation theory adopter categories were residents of states allowing pharmacist vaccination before 1996 ("innovator/early adopters"), between 1996 and 1998 ("early majority"), between 1999 and 2004 ("late majority"), and in 2007 or later ("laggards"). RESULTS: For adults aged 18 to 64 years, vaccination rates were similar before the innovation (1993), diverged as the innovation reached the majority (2003), and were significantly lower for laggard states by 2013. Younger adults' vaccination rates steadily increased from 12% to 16% in 1993 to 29% to 36% in 2013. For older adults, there was no significant difference in vaccination rates between adopter categories in any year and no advantage associated with adoption category. CONCLUSIONS: Key features of pharmacy-based vaccination, including relative advantage and compatibility, are most relevant to younger adults; different interventions are warranted for older adults.

Antibiotic prescribing by telephone in primary care.

OBJECTIVES: Little is known about the contribution of telephone-based prescribing on overall antibiotic utilization. The objective of this study was to determine the extent and characteristics of telephone-based antibiotic prescribing in teaching and non-teaching primary care practices. METHODS: This retrospective cohort study included all patients (n = 114 610) cared for by teaching and non-teaching internal medicine, pediatrics, family practice, and obstetrics/gynecology practices (n = 19) affiliated with a large US healthcare system during 2006-2010 and using a common electronic medical record. Rates and types of antibiotics prescribed by teaching and non-teaching practices via telephone contact and office visit were compared among the overall cohort. All telephone-related prescriptions during 2008 underwent chart review to determine indications for antibiotic prescribing. RESULTS: Overall, 28.9 antibiotic prescriptions were issued per 100 patient-years, with 63 418 total antibiotic prescriptions and 7876 (12.4%) generated after telephone contact. Telephone-based prescribing increased steadily from 2.2 to 4.2 per 100 patient-years during the study period. Both telephone-based and office-based antibiotic prescribing were higher in non-teaching practices. Of 1790 antibiotics prescribed by telephone during 2008, the majority were for urinary tract infection (28.3%), sinusitis (20.1%), and unspecified upper respiratory infection (URI, 15.0%). CONCLUSIONS: Overall, one in every eight antibiotics was prescribed via telephone encounter. These data highlight the need to include the impact of this practice in analysis of outcomes associated with outpatient antibiotic prescribing and to incorporate telephonic prescribing into guidelines facilitating appropriate antibiotic use.

The ISPOR Good Practices for Quality Improvement of Cost-Effectiveness Research Task Force Report.

OBJECTIVES: The International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Health Science Policy Council recommended and the ISPOR Board of Directors approved the formation of a Task Force to critically examine the major issues related to Quality Improvement in Cost-effectiveness Research (QICER). The Council's primary recommendation for this Task Force was that it should report on the quality of cost-effectiveness research and make recommendations to facilitate the improvement of pharmacoeconomics and health outcomes research and its use in stimulating better health care and policy. Task force members were knowledgeable and experienced in medicine, pharmacy, biostatistics, health policy and health-care decision-making, biomedical knowledge transfer, health economics, and pharmacoeconomics. They were drawn from industry, academia, consulting organizations, and advisors to governments and came from Japan, the Netherlands, Canada and the United States. METHODS: Face-to-face meetings of the Task Force were held at ISPOR North American and European meetings and teleconferences occurred every few months. Literature reviews and surveys were conducted and the first preliminary findings presented at an open forum at the May 2008 ISPOR meeting in Toronto. The final draft report was circulated to the expert reviewer group and then to the entire membership for comment. The draft report was posted on the ISPOR Web site in April 2009. All formal comments received were posted to the association Web site and presented for discussion at the Task Force forum during the ISPOR 14th Annual International Meeting in May 2009. Comments and feedback from the forums, reviewers and membership were considered in the final report. Once Task Force consensus was reached, the article was submitted to Value in Health. CONCLUSIONS: The QICER Task Force recommends that ISPOR implement the following: * With respect to CER guidelines, that ISPOR promote harmonization of guidelines, allowing for differences in application, regional needs and politics; evaluate available instruments or promote development of a new one that will allow standardized quantification of the impact of CER guidelines on the quality of CER studies; report periodically on those countries or regions that have developed guidelines; periodically evaluate the quality of published studies (those journals with CER guidances) or those submitted to decision-making bodies (as public transparency increases). * With respect to methodologies, that ISPOR promote publication of methodological guidelines in more applied journals in more easily understandable format to transfer knowledge to researchers who need to apply more rigorous methods; promote full availability of models in electronic format to combat space restrictions in hardcopy publications; promote consistency of methodological review for all CER studies; promote adoption of explicit best practices guidelines among regulatory and reimbursement authorities; periodically update all ISPOR Task Force reports; periodically review use of ISPOR Task Force guidelines; periodically report on statistical and methodological challenges in HE; evaluate periodically whether ISPOR's methodological guidelines lead to improved quality; and support training and knowledge transfer of rigorous CER methodologies to researchers and health care decision-makers. * With respect to publications, that ISPOR develop standard CER guidances to which journals will be able to refer their authors and their reviewers; lobby to establish these guidances within the International Committee for Medical Journal Editors (ICMJE) Requirements to which most journals refer in their Author Instructions; provide support in terms of additional reviewer expertise to those journals lacking appropriate reviewers; periodically report on journals publishing CER research; periodically report on the quality of CER publications; and support training and knowledge transfer of the use of these guidelines to researchers and reviewers. * With respect to evidence-based health-care decision-making, that ISPOR recognize at its annual meetings those countries/agencies/private companies/researchers using CER well, and those practitioners and researchers supporting good patient use of CER in decision-making; and promote public presentation of case studies of applied use of CER concepts or guidelines.

Pharmacoeconomic impact of non-compliance with statins.

There are numerous studies examining the pharmacoeconomic impact of HMG-CoA reductase inhibitor (statin) therapy on healthcare costs and outcomes. A recently published review demonstrated that the cost-benefit of these agents depends primarily on the risk of developing a coronary event. That is, as the risk of a coronary event increases, the cost-effectiveness ratio decreases. The typical cost per life-year saved (LYS) ranged from USD 1800 to USD 40,000 in patients with pre-existing coronary artery disease (CAD) and from USD 15,000 to > USD 1 million per LYS in patients without pre-existing CAD. The literature is sparse on the pharmacoeconomics of medication non-compliance in patients taking statin medications. Data from two studies suggest that >75% compliance results in decreased coronary events such as myocardial infarction. However, retrospective database analyses indicate that the average compliance rate hovers around the 65% mark. Many of the studies discuss medication non-compliance as a factor, but do not independently analyse compliance pharmacoeconomically. We examined the pharmacoeconomic impact of non-compliance using published studies that contained pharmacoeconomic data and/or compliance data. In general, we used the placebo arm of these published studies as the surrogate marker for complete non-compliance. The results suggest that for almost 100% compliance versus initial non-compliance, the cost effectiveness of statin medications ranges from USD 4500 to over USD 250,000 per LYS depending on patient age, presence or absence of risk factors and whether the statin is being used for primary or secondary prevention. Alternate-day or weekly dosing studies were also used to examine the impact of compliance on cost and health outcomes. Alternate-day dosing represented 50% compliance and weekly dosing 29% compliance. Less than full compliance had the expected effect of worse health outcomes and lower drug costs. However, the studies were small and not designed as true pharmacoeconomic studies looking at the relationship between medication compliance and cost. The results of this review suggest that there needs to be further examination of the relationship between compliance with statins and cost effectiveness, and studies need to include compliance in their data collection and analysis.

Overactive bladder patients and role of the pharmacist.

OBJECTIVES: To summarize the prevalence, quality of life (QOL) implications, cost of illness, and pharmacotherapy of overactive bladder (OAB), and to describe the pharmacist's role in the management of patients with OAB. DATA SOURCES: Articles published between 1990 and 2001 identified through a MEDLINE search using the terms overactive bladder, unstable bladder, urinary incontinence, prevalence, cost of illness, quality of life, drug therapy, pharmacist, and pharmacy in various combinations. STUDY SELECTION: All studies providing information on OAB or urinary incontinence were retrieved. DATA EXTRACTION: By the authors. DATA SYNTHESIS: Published prevalence and cost studies focus primarily on urinary incontinence, which is only one possible symptom of OAB. Reported prevalence rates of urge and mixed incontinence in the United States range from 3% to 8% and 5% to 37%, respectively, and the highest prevalence has been found in geriatric and psychogeriatric populations. Associated costs are substantial. Total costs of OAB in the United States were estimated to be $12.6 billion in 2000. Patients with OAB score lower than the general population in QOL assessments. All aspects of QOL can be compromised by OAB, as physical, social, occupational, domestic, and sexual activities are often limited in OAB patients. The pharmacist is instrumental in improving an individual's QOL through ensuring safe and effective treatment for OAB. Oxybutynin and tolterodine (Detrol-Pharmacia) have been the mainstays of pharmacotherapy for OAB, but frequent adverse effects (including dry mouth) often prevent patients from adhering to treatment. Tolterodine, now available in a new long-acting formulation, has been proven safe and efficacious in the treatment of OAB, with fewer adverse effects and better tolerability than existing agents. CONCLUSION: Pharmacists can play an active role in helping identify and recommending interventions for OAB that can ultimately improve an individual's QOL.
