Adherence and persistence of HIV pre-exposure prophylaxis use in the United States

PURPOSE

To describe medication adherence and persistence of HIV PrEP overall and compare between sex and age groups of commercially insured individuals in the United States.

METHODS

We conducted a national retrospective cohort study of the Merative MarketScan Claims Database from 2011 to 2019 to describe adherence and persistence of PrEP overall and compared between sex and age groups. High adherence was defined as ≥80% of proportion of days covered and persistence was measured in days from initiation to the first day of a 60-day treatment gap.

RESULTS

A total of 29 689 new PrEP users identified. Overall adherence was high (81.9%; 95% confidence interval [CI]: 81.5%-82.3%). Females were more adherent than males (adjusted odds ratio [aOR] 1.87; 95% CI: 1.50-2.34), while those ≥45-years were less adherent than individuals <45-years (aOR 0.87: 95% CI: 0.81-0.93). More than half of individuals discontinued therapy within the first year (median 238.0 days; interquartile range 99.0-507.0 days). Females were less persistent than males (hazard ratio [HR] 1.49; 95% CI: 1.34-1.65), and people ≥45-years old were more persistent (i.e., lower risk of discontinuation) than those <45-years (HR 0.43; 95% CI: 0.33-0.55).

CONCLUSIONS

These findings show adherence to daily PrEP is high among commercially insured individuals but the majority still discontinue in the first year. Future research should investigate what factors influence PrEP discontinuation among this population and ways to reduce barriers to therapy maintenance to ensure the population-level benefits of PrEP treatment.

Integrated antibody and cellular immunity monitoring are required for assessment of the long term protection that will be essential for effective next generation vaccine development

The COVID pandemic exposed the critical role T cells play in initial immunity, the establishment and maintenance of long term protection, and of durable responsiveness against novel viral variants. A growing body of evidence indicates that adding measures of cellular immunity will fill an important knowledge gap in vaccine clinical trials, likely leading to improvements in the effectiveness of the next generation vaccines against current and emerging variants. In depth cellular immune monitoring in Phase II trials, particularly for high risk populations such as the elderly or immune compromised, should result in better understanding of the dynamics and requirements for establishing effective long term protection. Such analyses can result in cellular immunity correlates that can then be deployed in Phase III studies using appropriate, scalable technologies. Measures of cellular immunity are less established than antibodies as correlates of clinical immunity, and some misconceptions persist about cellular immune monitoring usefulness, cost, complexity, feasibility, and scalability. We outline the currently available cellular immunity assays, review their readiness for use in clinical trials, their logistical requirements, and the type of information each assay generates. The objective is to provide a reliable source of information that could be leveraged to develop a rational approach for comprehensive immune monitoring during vaccine development.

Trends of nonoccupational postexposure prophylaxis in the United States

OBJECTIVE

To describe national annual rates of nonoccupational postexposure prophylaxis (nPEP) in the United States.

DESIGN

Retrospective cohort study of commercially insured individuals in the Merative MarketScan Database from January 1, 2010 to December 31, 2019.

METHODS

Patients at least 13 years old prescribed nPEP per recommended Centers for Disease Control and Prevention guidelines were identified using pharmacy claims. Rates of use were described overall and stratified by sex, age group, and region. These rates were qualitatively compared to the diagnosis rates of human immunodeficiency virus (HIV) observed in the data. Joinpoint analysis identified inflection points of nPEP use.

RESULTS

Eleven thousand, three hundred and ninety-seven nPEP users were identified, with a mean age of 33.7 years. Most were males (64.6%) and lived in the south (33.2%) and northeast (32.4%). The rate of nPEP use increased 515%, from 1.42 nPEP users per 100 000 enrollees in 2010 to 8.71 nPEP users per 10 000 enrollees in 2019. The comparative nPEP use rates among subgroups largely mirrored their HIV diagnosis rates, that is, subgroups with a higher HIV rate had higher nPEP use. In the Joinpoint analysis significant growth was observed from 2012 to 2015 [estimated annual percentage change (EAPC): 45.8%; 95% confidence interval (CI): 29.4 - 64.3] followed by a more moderate increase from 2015 to 2019 (EAPC 16.0%; 95% CI: 12.6-19.6).

CONCLUSIONS

nPEP use increased from 2010 to 2019, but not equally across all risk groups. Further policy interventions should be developed to reduce barriers and ensure adequate access to this important HIV prevention tool.

Adherence to HIV Pre-Exposure Prophylaxis Testing Guidelines in the United States

Testing guidelines for initiation of pre-exposure prophylaxis (PrEP) for human immunodeficiency virus (HIV) have been developed to ensure appropriate use of PrEP, such as among those with renal dysfunction or at high risk of seroconversion. While many studies have looked at the trends of use of PrEP in the United States, little is known about compliance with these guidelines, the quality of care of PrEP at a national level, or what provider-level factors are associated with high-quality care. We conducted a retrospective claims analysis of providers of commercially insured new users of PrEP between January 1, 2011, and December 31, 2019. Of the 4200 providers, quality of care was low, with only 6.4% having claims for ≥60% of guideline-recommended testing for their patients in the testing window for all visits. More than half of the providers did not have claims for HIV testing at initiation of PrEP and ≥40% did not for sexually transmitted infections at both initiation and follow-up visits. Even when extending the testing window, quality of care remained low. Logistic regression models found no association between provider type and high quality of care, but did find that providers with one PrEP patient were more likely to have higher quality of care than those with multiple patients for all tests [adjusted odds ratio 0.47 (95% confidence interval: 0.33-0.67)]. The study findings suggest further training and interventions, such as integrated test ordering through electronic health records, are needed to increase quality of care for PrEP and ensure appropriate monitoring of patients.

Cellular Immunity Is Critical for Assessing COVID-19 Vaccine Effectiveness in Immunocompromised Individuals

COVID-19 vaccine clinical development was conducted with unprecedented speed. Immunity measurements were concentrated on the antibody response which left significant gaps in our understanding how robust and long-lasting immune protection develops. Better understanding the cellular immune response will fill those gaps, especially in the elderly and immunocompromised populations which not only have the highest risk for severe infection, but also frequently have inadequate antibody responses. Although cellular immunity measurements are more logistically complex to conduct for clinical trials compared to antibody measurements, the feasibility and benefit of doing them in clinical trials has been demonstrated and so should be more widely adopted. Adding significant cellular response metrics will provide a deeper understanding of the overall immune response to COVID-19 vaccination, which will significantly inform vaccination strategies for the most vulnerable populations. Better monitoring of overall immunity will also substantially benefit other vaccine development efforts, and indeed any therapies that involve the immune system as part of the therapeutic strategy.

A safe in-home disposal system with every opioid prescription? Food and Drug Administration is considering a potential new Risk Evaluation and Mitigation Strategy that could impact pharmacists

Misuse of prescription opioids contributes to the ongoing crisis of opioid-related overdose and deaths in the United States. The failure of patients and caregivers to safely dispose of unused opioids contributes to the problems. In 2018, Public Law 115-271 provided the U.S. Food and Drug Administration (FDA) authority to mandate a Risk Evaluation and Mitigation Strategy (REMS) for safe disposal packaging or safe disposal solutions for opioid analgesic medications. The FDA has been collaborating with stakeholders to determine whether a new REMS is needed. A new or revised opioid REMS could substantially affect opioid packaging, pharmacist roles and services, and dispensing activities such as education, counseling, and product distribution. The pharmacy profession has provided limited input to FDA regarding a potential new or revised opioid REMS. In this commentary, we aim to (1) provide awareness and raise questions on pertinent issues regarding opioid use and safe home disposal, (2) offer considerations for regulators on needed research in the development and assessment of a new REMS, and (3) highlight actions for pharmacist engagement in patient care services to promote safe use and safe home disposal of opioids. Consideration of a potential mandate regarding enhanced safety packaging or safe disposal solutions for opioids presents opportunities to revisit professional roles and engage proactively with the FDA and other stakeholders. We hope this commentary stimulates timely feedback by pharmacy leaders, researchers, and practitioners on whether and how options for safe home disposal of opioids should be included in a REMS in contemplation of potential benefits, unintended consequences, expanded professional roles, timeline, assessment of program effectiveness, and adequate compensation. We support a shared opioid REMS that funds the counseling of patients and caregivers on safe opioid use and safe home opioid disposal options and provides appropriate education and products to facilitate that disposal.

A faculty and staff workshop on microaggression and implicit bias: Knowledge and awareness of student, faculty, and staff experiences

BACKGROUND AND PURPOSE

This paper describes the context and experiences of a workshop to raise knowledge and awareness of a college of pharmacy's faculty and staff about microaggressive behaviors and implicit biases. The workshop was intended to provide a non-threatening, interactive, and informative professional development program to demonstrate the cumulative marginalizing effects on students, faculty, and staff who may perceive themselves as targets.

EDUCATIONAL ACTIVITY AND SETTING

A half-day workshop was conducted during July 2018. Participants were initially provided with definitions and categories of microaggression and implicit bias. To bring the subject matter "alive" and foster receptivity, interactive videos were shown with scenarios depicting situations reflective of microaggressions and implicit biases. College faculty, staff, and students made these relatable. To foster objectivity, an outside consultant was hired to facilitate the ensuing roundtable and plenary discussions.

FINDINGS

Sixty-eight participants responded to a pre-survey designed by the workshop team, and 78% indicated never having attended a training/seminar on microaggression and/or implicit bias. Sixty-two individuals responded to the post-survey with 92% indicating increased knowledge gained from workshop. Anecdotal reports suggested that the workshop had an ongoing impact, as faculty and staff continued the discussions in subsequent months and requested additional training sessions.

SUMMARY

The workshop heightened awareness and increased faculty and staff knowledge on microaggressive behaviors, implicit biases, and the potential consequences thereof. It also demonstrated the importance of addressing conversations that are perceived as difficult, in order to create a diverse and inclusive workplace and learning environment for all.

Narrative arcs and shaping influences in long-term medication adherence

Long-term adherence to medications is not well understood and poses a significant challenge for many chronically ill persons. Past research provides insights on adherence in short durations such as a day or several weeks, even though chronically ill patients are required to take medications for periods as long as a lifetime. To fill this important knowledge gap, we study the temporal unfolding of prolonged medication-taking experiences among thirty adults, mostly African American, with chronic hypertension in the U.S. Specifically, we take an extended, experience-centered, narrative approach to examine retrospective patient accounts of adherence efforts over spans of one year to more than four decades. Applying Gergen and Gergen's concept of narrative forms (1983), we find four distinct narrative arcs, or patterned sequences of medication consumption, that we term Out of the Gate, Existential Turn, Fits and Starts, and Slow Climb, along with individual and social elements that shape and shift practices in the context of time.

Secondary effects of an opioid-focused academic detailing program on non-opioid controlled substance prescribing in primary care

Background: Educational outreach programs that focus on safe opioid prescribing and awareness of state prescription monitoring programs may modify clinicians' prescribing behavior. The objective of this study was to evaluate the secondary effects of an opioid-focused academic detailing (AD) program on non-opioid controlled substance prescribing in primary care. Methods: A quasi-experimental pre-post study of primary care clinicians exposed and unexposed to the AD program was conducted using data from the Illinois Prescription Monitoring Program from December 2017 to February 2019. Outcomes were mean monthly prescriptions for benzodiazepines (BZD), non-BZD sedative-hypnotics, and carisoprodol, per clinician. A difference-in-differences (DID) approach utilizing repeated-measures mixed-effects linear regression models was used to compare changes in outcomes six-months before and after the program. Results: Mean monthly BZD prescriptions declined in both groups of clinicians (AD-exposed n = 151; controls n = 399) after implementation of the AD program. Although the mean monthly number of BZD prescriptions decreased in both groups after the AD program, BZD prescribing in the AD-exposed group declined at a slower rate following the AD program (DID = 0.73; 95% CI: 0.14, 1.31). The AD-exposed group had a 0.06 (95% CI: -0.11, -0.01) lower rate of mean monthly carisoprodol prescriptions compared to the control group following the AD program. There was no change in the rate of mean monthly non-BZD sedative-hypnotic prescriptions between the two groups. Conclusions: The higher relative rate of BZD prescribing in the AD-exposed group compared to the control group following the AD program may be reflective of an unintended consequence of opioid-focused AD programs as clinicians learn to be cautious about opioid prescribing. Our findings may suggest the need for incorporation of targeted education on appropriate BZD prescribing into opioid-focused AD programs as a featured component. These findings warrant further consideration and investigation before large-scale implementation of opioid-focused educational outreach programs.

Impact of adverse event reports from marketing authorization holder-sponsored patient support programs on the performance of signal detection in pharmacovigilance

OBJECTIVES

Marketing authorization holder (MAH)-sponsored patient support programs (PSPs) are a major source of adverse event (AE) reports. The impact of reports from PSPs on the ability to detect AE signals is unclear. We compared signal detection performance using data from PSPs vs. non-PSP sources, and between PSPs providing clinical services vs. PSPs not providing clinical services.

METHODS

Data were obtained from an internal safety database for a global pharmaceutical company 2015-2017. We assessed whether signals were detected for the reference drug-AE pairs using data from PSPs vs. non-PSP sources, and among different PSP services. The performance was evaluated by four measures including area under the receiver operating characteristic curve (AUC) and time-to-signal detection.

RESULTS

While the majority of reports were from PSPs, non-PSP sources were better and faster at detecting signals (AUC 0.63 vs. 0.41, p = 0.035; HR 3.52, p = 0.014) compared to PSPs. Within PSPs, PSPs providing clinical services were marginally better at detecting signals (AUC 0.60 vs. 0.41, p = 0.053) but not faster compared to PSPs not providing clinical services.

CONCLUSION

Reports of AEs from PSPs had worse signal detection performance compared to non-PSP sources. Pharmacovigilance experts should be mindful when using databases that contain reports from PSPs for signal detection.

Patient-centered design in developing a mobile application for oral anticancer medications

OBJECTIVES

To develop and test the usability and feasibility of a customizable mobile application (app) designed to help educate patients about their oral anticancer medications (OAMs) and regimens.

SETTING

Outpatient cancer center and oncology pharmacy for urban, Midwestern academic health system.

PRACTICE DESCRIPTION

Clinically-supervised educational intervention to support patients learning about OAMs.

PRACTICE INNOVATION

With input from patient partners, our interdisciplinary team designed the first known tablet-based educational app that can interface with a patient's electronic medical record. The app is based on learning style and adherence theories and is customizable for individually prescribed OAMs. The app can accommodate multiple learning styles through text at 6th-grade reading level, pictures, animations, and audio voiceovers. Functionalities include interactive educational modules on 11 OAMs and case-based patient stories on common barriers to OAM adherence.

EVALUATION

Early phase testing provided the opportunity to observe the user interface with the app and app functionality. Data were summarized descriptively from observations and comments of patient subjects.

RESULTS

Thirty patient subjects provided input-19 in phase 1 usability testing and 11 in phase 2 feasibility testing. Comments provided by patient subjects during usability testing were largely positive. Responses included self-identification with patient stories, usefulness of drug information, preferences for text messages, and app limitations (e.g., perceived generational digital divide in technology use and potential patient inability to receive text messages). Using their feedback, modifications were made to the prototype app. Responses in feasibility testing demonstrated the app's usefulness across a wide range of ages. Highest opinion ratings on app usefulness were stated by patients who were newer to OAM therapy.

CONCLUSION

User feedback suggests the potential benefit of the app as a tool to help patients with cancer, particularly after the first months for those starting new OAM regimens. Processes and lessons learned are transferable to other settings.

Drug Shortage Impacts Patient Receipt of Induction Treatment

OBJECTIVE

Examine the impact of the 2011 shortage of the drug cytarabine on patient receipt and timeliness of induction treatment for Acute Myeloid Leukemia (AML).

STUDY DESIGN

A retrospective cohort was utilized to examine odds of receipt of inpatient induction chemotherapy and time to first dose across major (N = 105) and moderate (N = 316) shortage time periods as compared to a nonshortage baseline (N = 1,147).

DATA COLLECTION/EXTRACTION METHODS

De-identified patient data from 2008 to 2011 Surveillance, Epidemiology, and End Results (SEER) were linked to 2007-2013 Medicare claims and 2007-2013 Hospital Characteristics.

PRINCIPAL FINDINGS

Compared to prior nonshortage time period, patients diagnosed during a major drug shortage were 47 percent less likely (p < .05) to receive inpatient chemotherapy within 14 days of diagnosis. Patients who were younger, had a lower Charlson Comorbidity score, and for whom AML was a first primary cancer were prioritized across all periods.

CONCLUSIONS

Period of major shortage of a generic oncolytic, without an equivalent therapeutic substitute, reduced timely receipt of induction chemotherapy treatment. More favorable economic and regulatory policies for generic drug suppliers might result in greater availability of essential, older generic drug products that face prolonged or chronic shortage.

Assessing Students' Impressions of the Cultural Awareness of Pharmacy Faculty and Students

Objective. To determine pharmacy students' impressions of their faculty's interactions with diverse student and patient populations. Methods. Three student focus groups were convened. Eighty-four page transcripts were coded, and emergent themes were identified by qualitative analysis. Results. Students defined diversity as multidimensional beyond traditional categories. Emergent themes were faculty awareness or lack of awareness of cultural diversity, disparate cultural perspectives and preferences within student groups, teaching/learning approaches to prepare students to be more culturally competent, and student group dynamics. First- and second-year students emphasized student-to-student interactions, while third- and fourth-year students emphasized a lack of preparation for the realities of contemporary practice based on instructional methods. Conclusion. Students perceived the majority of their pharmacy faculty to be culturally sensitive and aware, but microaggression and discrimination from faculty and student peers were experienced. Study implications can potentially improve curricular offerings, cultural awareness of faculty and students, and care to diverse patient populations.

Design of Customized Mobile Application for Patient Adherence to Oral Anticancer Medications Utilizing User-Centered Design

Adherence and compliance to oral anticancer medications (OAMs) can be challenging for patients due to their complex regimens. The goal of this research project was to design an effective and engaging user interface (UI), based on user-centered design (UCD) and incorporate animations, to reinforce and improve patient's understanding of the key aspects of taking OAMs. This current paper encompasses the development process and describes the initial phase of the project, which focused on the design and development of the tablet-based educational application (app). A UCD approach was implemented by consulting with oncology clinicians and patients at an early stage of development. Animations were developed and incorporated to convey complex medical concepts and information. An iterative design process will help ensure that the tool is customized for patient engagement.

The Science of Safety – An Emerging Concept in Medication Use and Research

Most published reports of patient safety in clinical practice focus largely on the culture of safety in complex health systems, separate from pre-approval and postmarketing research-related safety considerations for drugs, biologics, and other medical products. The science of safety requires a linked integrated perspective, i.e., an iterative process examining and relating safety concerns from drug or biologic discovery and development in preclinical stages, clinical trials and post-market use, research, surveillance, and potential regulatory changes. This commentary addresses the science of safety across the lifecycle of drug and biological products, regulatory considerations, barriers, and research needs. This paper provides a brief overview on how the functioning of healthcare systems affects the safety environment and describes how stakeholder involvement, research participation, and targeted education and training can help facilitate better safety measures and practices, provide improved quality of care to patients, and contribute to the science of safety.

A Comparative Analysis of Perceptions of Pharmacy Students' Stress and Stressors across Two Multicampus Universities

Objective. To compare perceived levels of stress, stressors, and academic self-efficacy among students at two multicampus colleges of pharmacy. Methods. A survey instrument using previously validated items was developed and administered to first-year, second-year, and third-year pharmacy students at two universities with multiple campuses in spring 2013. Results. Eight hundred twenty students out of 1115 responded (73.5% response rate). Institutional differences were found in perceived student stress levels, self-efficacy, and stress-related causes. An interaction effect was demonstrated between institution and campus type (main or branch) for perceived stress and self-efficacy although campus type alone did not demonstrate a direct effect. Institutional and campus differences existed in awareness of campus counseling services, as did a few differences in coping methods. Conclusion. Stress measures were similar for pharmacy students at main or branch campuses. Institutional differences in student stress might be explained by instructional methods, campus support services, institutional climate, and nonuniversity factors.

A Cross Sectional and Longitudinal Study of Pharmacy Student Perceptions of Readiness to Serve Diverse Populations

Objective. To examine students' self-perceptions at different stages in a pharmacy curriculum of competence related to serving culturally diverse patients and to compare self-reported competence of a student cohort near the beginning and end of the degree program. Methods. Student perceptions across four pharmacy class years were measured in a cross-sectional survey, with a follow-up longitudinal survey of one cohort three years later. Results. Based on an 81.9% response rate (537/656), scores showed no attitude changes. Reported knowledge, skills, comfort in clinical encounters, and curricular preparedness increased across program years. Fourth-year (P4) pharmacy students reported the highest scores. Scores differed by gender, age, and race/ethnicity. Students in the fourth year scored lower on importance of diversity training. Conclusion. Improved perceptions of readiness (ie, knowledge and behavior) to serve diverse groups suggest the curriculum impacts these constructs, while the invariance of student attitudes and association of self-reports with programmatic outcomes warrant further investigation.

Comparison of pharmacy services at critical access hospitals and other rural and small hospitals in Illinois

PURPOSE

The results of a survey evaluating pharmacy services and technology use at critical access hospitals (CAHs) and other small and rural hospitals in Illinois are reported.

METHODS

A mail survey was sent to pharmacy directors at 86 CAHs and other rural and small hospitals in Illinois not designated as CAHs. Independent sample t tests and chi-square statistics were used to compare CAHs and non-CAHs in areas such as pharmacy services, staffing, use of technology, and sterile compounding practices.

RESULTS

The survey response rate was 46.5%, with usable data received from 40 hospitals. Analysis of the survey data indicated that hospitals designated as CAHs were significantly less likely than non-CAHs to have automatic therapeutic interchange policies (p = 0.012) and more likely to conduct pharmacist-provided educational programs on medication costs for physicians and other health care personnel (p = 0.037). Relative to non-CAHs, CAHs were significantly less likely to have automated dispensing cabinets (p = 0.016) and to out-source the preparation of sterile products to offsite vendors (p = 0.012); pharmacy directors at CAHs were less likely to report the use of technology for remote medication order entry or review (p = 0.038). At both types of facilities, pharmacists typically have both distributive and clinical responsibilities, and patient-specific clinical pharmacy services (e.g., patient education or counseling, other drug therapy monitoring, medication reconciliation, pharmacokinetic consultations) are offered at similar frequencies.

CONCLUSION

A survey of pharmacy departments at small and rural hospitals in Illinois determined that there were more similarities than differences between CAHs and non-CAHs. The survey indicated significant differences in dispensing processes, the use of technology and drug policy tools, and outsourcing of sterile product preparation.

Improving refill adherence and hypertension control in black patients: Wisconsin TEAM trial

OBJECTIVE

To assess the effectiveness and sustainability of a 6-month Team Education and Adherence Monitoring (TEAM) intervention for black patients with hypertension in community chain pharmacies.

DESIGN

Cluster randomized trial.

SETTING

28 chain pharmacies (14 TEAM and 14 control) in five Wisconsin cities from December 2006 to February 2009.

PARTICIPANTS

576 black patients with hypertension.

INTERVENTION

Trained pharmacist-technician teams implemented a 6-month intervention using scheduled visits, Brief Medication Questionnaires (BMQs), and novel toolkits for facilitating medication adherence and pharmacist feedback to patients and physicians. Control participants received patient information only.

MAIN OUTCOME MEASURES

Refill adherence (≥80% days covered) and changes in systolic blood pressure (SBP), diastolic blood pressure, and blood pressure control using blinded assessments at 6 and 12 months.

RESULTS

At baseline, all patients had blood pressure of 140/90 mm Hg or more. Of those eligible, 79% activated the intervention (mean 4.25 visits). Compared with control participants at 6 months, TEAM participants achieved greater improvements in refill adherence (60% vs. 34%, P < 0.001), SBP (-12.62 vs. -5.31 mm Hg, P < 0.001), and blood pressure control (50% vs. 36%, P = 0.01). Six months after intervention discontinuation, TEAM participants showed sustained improvements in refill adherence ( P < 0.001) and SBP ( P = 0.004), though the difference in blood pressure control was not significant ( P < 0.05) compared with control participants. Analysis of intervention fidelity showed that patients who received the full intervention during months 1 through 6 achieved significantly greater 6- and 12-month improvements in refill adherence and blood pressure control compared with control participants.

CONCLUSION

A team-based intervention involving community chain pharmacists, pharmacy technicians, and novel toolkits led to significant and sustained improvements in refill adherence and SBP in black patients with hypertension.

Comparison of learning styles of pharmacy students and faculty members

OBJECTIVES

To compare dominant learning styles of pharmacy students and faculty members and between faculty members in different tracks.

METHODS

Gregorc Style Delineator (GSD) and Zubin's Pharmacists' Inventory of Learning Styles (PILS) were administered to students and faculty members at an urban, Midwestern college of pharmacy.

RESULTS

Based on responses from 299 students (classes of 2008, 2009, and 2010) and 59 faculty members, GSD styles were concrete sequential (48%), abstract sequential (18%), abstract random (13%), concrete random (13%), and multimodal (8%). With PILS, dominant styles were assimilator (47%) and converger (30%). There were no significant differences between faculty members and student learning styles nor across pharmacy student class years (p>0.05). Learning styles differed between men and women across both instruments (p<0.01), and between faculty members in tenure and clinical tracks for the GSD styles (p=0.01).

CONCLUSION

Learning styles differed among respondents based on gender and faculty track.

An innovative seminar course in business etiquette for pharmacy graduate students

OBJECTIVES

To develop and implement a seminar course for graduate students in the social and administrative pharmaceutical sciences to enhance knowledge and confidence with respect their abilities to demonstrate appropriate business etiquette.

DESIGN

A 1-credit graduate seminar course was designed based on learner-centered constructivist theory and application of Fink's Taxonomy for Significant Learning.Assessment. Eleven students participated in the spring 2011 seminar course presentations and activities. Students completed pre- and post-assessment instruments, which included knowledge and attitudinal questions. Formative and summative assessments showed gains in student knowledge, perceived skills, and confidence based on observation and student-reported outcomes.

CONCLUSION

Graduate student reaction to the course was overwhelmingly positive. The etiquette course has potential application in doctor of pharmacy education, other graduate disciplines, undergraduate education, and continuing professional development.

The impact of Medicare Part D on out-of-pocket costs for prescription drugs, medication utilization, health resource utilization, and preference-based health utility

OBJECTIVES

To quantify the impact of Medicare Part D eligibility on medication utilization, emergency department use, hospitalization, and preference-based health utility among civilian noninstitutionalized Medicare beneficiaries.

STUDY DESIGN

Difference-in-differences analyses were used to estimate the effects of Part D eligibility on health outcomes by comparing a 12-month period before and after Part D implementation using the Medical Expenditure Panel Survey. Models adjusted for sociodemographic characteristics and health status and compared Medicare beneficiaries aged 65 and older with near elderly aged 55-63 years old.

PRINCIPAL FINDINGS

Five hundred and fifty-six elderly and 549 near elderly were included. After adjustment, Part D was associated with a U.S.$179.86 (p=.034) reduction in out-of-pocket costs and an increase of 2.05 prescriptions (p=.081) per patient year. The associations between Part D and emergency department use, hospitalizations, and preference-based health utility did not suggest cost offsets and were not statistically significant.

CONCLUSIONS

Although there was a substantial reduction in out-of-pocket costs and a moderate increase in medication utilization among Medicare beneficiaries during the first year after Part D, there was no evidence of improvement in emergency department use, hospitalizations, or preference-based health utility for those eligible for Part D during its first year of implementation.

An instrument to evaluate pharmacists' patient counseling on herbal and dietary supplements

OBJECTIVE

To develop a measure of pharmacists' patient counseling on herbal and dietary supplements.

METHODS

A systematic process was used for item generation, testing, and validation of a measure of pharmacists counseling on herbal and dietary supplements. Because a pharmacist-patient encounter may or may not identify an indication for taking an herb or dietary supplement, the instrument was bifurcated into 2 distinct components: (1) patient counseling in general; and (2) patient counseling related to herbal and dietary supplements.

RESULTS

The instrument demonstrated high reliability and desirable construct validity. After adjusting for item difficulty, we found that pharmacists tended to provide more general patient counseling than counseling related to herbal and dietary supplements.

CONCLUSION

This instrument can be applied to assess the quality of counseling provided by pharmacists and pharmacy students, and the outcomes of pharmacist and pharmacy student education on herbal and dietary supplements.

The Team Education and Adherence Monitoring (TEAM) trial: pharmacy interventions to improve hypertension control in blacks

Recent studies suggest that involving pharmacists is an effective strategy for improving patient adherence and blood pressure (BP) control. To date, few controlled studies have tested the cost-effectiveness of specific models for improving patient adherence and BP control in community pharmacies, where most Americans obtain prescriptions. We hypothesized that a team model of adherence monitoring and intervention in corporately owned community pharmacies can improve patient adherence, prescribing, and BP control among hypertensive black patients. The Team Education and Adherence Monitoring (TEAM) Trial is a randomized controlled trial testing a multistep intervention for improving adherence monitoring and intervention in 28 corporately owned community pharmacies. Patients in the 14 control pharmacies received "usual care," and patients in the 14 intervention pharmacies received TEAM Care by trained pharmacists and pharmacy technicians working with patients and physicians. Data collectors screened 1250 patients and enrolled 597 hypertensive black patients. The primary end points were the proportion of patients achieving BP control and reductions in systolic and diastolic BP measured after 6 and 12 months. Secondary end points were changes in adherence monitoring and intervention, patient adherence and barriers to adherence, prescribing, and cost-effectiveness. Researchers also will examine potential covariates and barriers to change. Involving pharmacists is a potentially powerful means of improving BP control in blacks. Pharmacists are in an excellent position to monitor patients between clinic visits and to provide useful information to patients and physicians.

Neighborhood geographical factors and the presence of advanced community pharmacy practice sites in Greater Chicago

OBJECTIVES

To determine the availability of experiential learning opportunities in culturally diverse areas and to identify opportunities and barriers to attract and sustain sites for the University of Illinois at Chicago College of Pharmacy.

METHODS

Utilizing variables of census tract income, racial/ethnicity composition and crime index, data analyses included descriptive statistics and multivariate logistic regression. Faculty members involved in experiential education were interviewed to identify other factors influencing site placement and selection for community-based advanced pharmacy practice experiences (APPEs).

RESULTS

Median family income and Asian population were significantly higher and black population was significantly lower in census tracts with community APPE sites than in census tracts without APPE sites (p < 0.05). No significant differences were found in the population variables of white and Latino populations and crime index. The Asian population variable was the only significant predictor of an APPE site (p = 0.0148) when controlling for other variables. Distance from the College, pharmacy staffing issues, goodwill, influence of district and corporate managers, and strategic initiatives were critical considerations in site establishment and overall sustainability.

CONCLUSION

Advanced community pharmacy practice sites were fairly well distributed across metropolitan Chicago, indicating that exposure to diverse populations during the advanced community practice experiences parallels with strategic College objectives of expanding and diversifying experiential sites to enhance pharmacy students' abilities to meet emerging patient care challenges and opportunities.

An online debate series for first-year pharmacy students

OBJECTIVES

This article describes an online debate series that was developed as a new component to an introductory core course for first-professional year pharmacy students. Objectives were to facilitate the group process, introduce controversial issues related to the US healthcare system, improve critical thinking and communication skills, enable students' ability to analyze and evaluate evidence, help develop skills in formulating written arguments, and encourage tolerance of diverse points of view.

DESIGN

One hundred sixty-two students were assigned to 40 teams (half assigned to argue as "Pros" and half as "Cons") and paired into 20 debating groups. The paired teams posted 3 arguments in an online forum alternatively over a 12-week period. The winning teams were determined by a panel of 3 judges.

ASSESSMENT

Feedback from the judges was posted online and summarized in an in-class discussion. Thematic analysis of qualitative data from students and faculty members demonstrated the effectiveness of the online debate component in helping students work together in a group, learn alternative sides of complex issues, and write persuasive arguments.

CONCLUSION

This novel online-debate forum was a feasible teaching and learning strategy, which helped pharmacy students improve their communication skills and critical thinking, expanded their scope of knowledge, and provided a platform for group process.

Trend and area variation in amphetamine prescription usage among children and adolescents in Michigan

The increased use of stimulant medications for children and teenagers is an ongoing issue of professional and public concern. Unlike methylphenidate, the growth of prescriptions and patterns of utilization of amphetamines for pediatric populations have not been well documented. The study objectives were to describe the trends of amphetamine prescription utilization among pediatric age groups in Michigan and to compare area variations. A population-based computerized data set from the state of Michigan was used to extract all outpatient prescriptions for Schedule II amphetamines dispensed from 1990 to 1997. The prescribing rates by age groups and by counties were computed with the projected population size of corresponding years, and mapped and analyzed with spatial statistical methods. Counties that did not conform to the global spatial dependence pattern in the prescription rate were identified using Moran scatter plot. A total of 236,661 outpatient prescriptions for amphetamines were dispensed in Michigan during the time frame, including less than 1% for methamphetamine, 24.5% for amphetamine, and 74.8% for dextroamphetamine. The prescribing rate was highest among children 10-14 years old (380 prescriptions per 10,000 people) in 1997, followed by children 5-9 years old (253 prescriptions per 10,000). Over the 8-year period, the prescribing rates of amphetamines increased significantly, ranging from 380% for children 2-4 years to 817% for teenagers older than 14 years. The rates among counties ranged from 60 to 1648 per 10,000 children 5-14 years old, with the highest prescribing rates in the northwestern regions of Michigan. Although spatial dependence explained 36% of the variance, the area variations that are unaccounted for are still considerable. In conclusion, there were substantial increases and unexplained area variations in amphetamine usage in Michigan during the study period. Both phenomena require awareness and evaluation from researchers, policy makers, clinicians, and the public.

Potential access and revealed access to pain management medications

The area configuration of healthcare resources, such as the number of hospitals per hundred thousand population, has often been used in healthcare planning and policy making to estimate the global access (potential access) of health services to a local population. However, the actual utilization of the "available" healthcare resources (revealed access) is usually much more limited. The objectives of this study were to examine the availability of healthcare resources by measuring the potential access and the revealed access for outpatients who need to access pharmacies to fill prescriptions of Schedule II (CII) opioids for pain management, and to explore the difference between rural and urban residents in these two types of access. About 191,700 prescriptions for CII opioids dispensed in 1997 in the state of Michigan, USA were analyzed. Revealed accessibility was measured by the distance between the paired zip codes of the pharmacy and the patient listed on each prescription. Potential accessibility was measured by the distance from a patient's zip code to that of the nearest community pharmacy that could dispense the opioid prescriptions. The analyses on revealed access showed that 50% of the CII prescriptions were dispensed by pharmacies located within a 5-mile radius of patients' residences, 75% of prescriptions were dispensed within about a 10-mile radius, and 90% were within 20 miles. If patients were free to access the nearest pharmacy for dispensing (a hypothetical situation under potential access), the median, 75th percentile, and 90th percentile distances could reduce to 2, 3, and 5 miles, respectively. Similar differences between revealed and potential access were observed in both rural and urban areas and for every major opioid drug group. We conclude that policymakers should recognize the discrepancy between potential and revealed accessibility and move beyond only considering area configuration of healthcare resources to evaluating and improving access to care.

Systems factors in the reporting of serious medication errors in hospitals

Underreporting of medication errors poses a threat to quality improvement initiatives. Hospital risk management programs encourage medication error reporting for effective management of systems failures. This study involved a survey of 156 medical-surgical hospitals in the United States to evaluate systems factors associated with the reporting of serious medication errors. Prior to controlling for bed size, a multivariate logistic regression model showed increased reporting of medication errors in hospitals with 24-h pharmacy services, presumably because of better error reporting systems. When number of occupied beds was included, the final model demonstrated bed size to be the only statistically significant factor. Increased reporting rates for serious medication errors warrant further evaluation, but higher error reporting may paradoxically indicate improved error surveillance. Results suggest that increased availability of pharmacist services results in opportunities for more diligent systematic efforts in detecting and reporting medication errors, which should lead to improved patient safety.

Pharmaceutical services in rural hospitals in Illinois--2001

The results of a survey characterizing pharmaceutical services in rural hospitals in Illinois are reported and compared with results of a similar survey conducted in 1991. A questionnaire was developed and mailed to pharmacy directors at rural hospitals in Illinois to obtain information about product-related services, the use of technology, clinical pharmacy services, and human resources data (including vacancies) for 2001. Of the 71 surveys that were mailed, 47 pharmacy directors (66%) responded. Respondent hospitals were smaller compared with those responding in 1991 (mean average daily census, 41.0 versus 51.2, respectively). As in 1991, nearly all respondents reported the provision of unit dose services and complete and comprehensive i.v. admixture programs (100% and 83%, respectively, for 2001). Three respondents (6%) reported having a cleanroom facility. The most commonly used technology reported was nursing-unit-based automated drug dispensing cabinets (35%). Nearly all hospitals reported providing drug therapy monitoring, patient education and counseling, pharmacokinetic consultations, and nutritional support. Consistent with national reports, staffing levels and vacancies increased between 1991 and 2001. In 2001, the mean number of full-time equivalents was 7.1, with a pharmacist to technician ratio of 1.0:1.08 and a ratio of pharmacists to occupied beds of 1.0:22.6. The overall vacancy rate was 8%, with a vacancy rate of 14% and 5% for pharmacists and pharmacy technicians, respectively. A 2001 survey of pharmacy departments in rural hospitals in Illinois showed progression in the provision of distributive and clinical pharmacy services since 1991. Employee vacancy rates in pharmacy departments were high in 2001, especially among pharmacist positions, but were lower than those reported for the general population of hospitals.

This paper addresses issues pertaining to Internet pharmacies that sell prescriptions and other products to consumers at the retail level. The Internet pharmacy industry has shifted rapidly in the short time span. This paper begins with a summary of historical considerations and the shifting organization of Internet pharmacy. The advantages and disadvantages of online pharmacy practice are listed. Issues of access, quality, and cost are described. The challenges in regulation at the state and federal levels are presented. Advice to consumers is offered regarding the use of Internet pharmacy sites for purchasing prescription drug products.

National survey of stress ulcer prophylaxis

OBJECTIVE

To determine the rationale for using stress ulcer prophylaxis (SUP) among clinicians; to assess criteria used to define failure of SUP; and to evaluate the decision-making process in the selection of a prophylactic agent.

DESIGN

A cross-sectional national mail survey.

SETTING

Random sample of the members of the Society of Critical Care Medicine who identified anesthesiology, surgery, or internal medicine as their primary specialty area.

PATIENTS

None.

INTERVENTION

None.

MEASUREMENTS AND MAIN RESULTS

Questionnaires consisting of multiple-choice and short-answer questions were sent to a simple random sample of 1,268 physicians to assess the current practice of SUP. A total of 328 usable questions were returned, resulting in a response rate of 26%. All percentages reported in the results are based on the total number of responses. The risk factors for SUP that were most commonly identified were burns (91%), shock (90%), and sepsis (88%). These were also risk factors for which the respondents most commonly started SUP. Histamine-2-receptor (H2)-antagonists as a class, were the most commonly used prophylactic agents (67%). The most commonly used agents for SUP were ranitidine (31%), famotidine (24%), sucralfate (24%), and cimetidine (12%). Most respondents selected ranitidine for ease of administration, famotidine because of formulary availability, sucralfate for a better side effects profile, and cimetidine for cost-effectiveness. Eighty-two percent of respondents considered the presence of bright red blood in the nasogastric tube as failure of SUP. In cases where SUP failed, most respondents would add a second agent from a different therapeutic class. Of those respondents who used an H2-antagonist initially, 48% would add sucralfate, 36% would add antacid, and 13% would add omeprazole. Of those respondents who used sucralfate, 77% would add an H2-antagonist when SUP failed. For those respondents who would switch to another agent when the H2-antagonist failed, 52% would change to omeprazole, whereas 67% would change to an H2-antagonist when sucralfate failed. Only eight respondents would discontinue SUP when risk factors were resolved. Most respondents would discontinue SUP when the patient was no longer in the "nothing by mouth" status (28%), started on enteral feeding (23%), or discharged from the intensive care unit (21%). The mean duration of SUP was 6.3+/-4.5 (SD) days.

CONCLUSIONS

This survey highlighted the lack of consensus in the use of SUP. Many patients receive SUP for an extended period, without clear-cut indications or documented benefit. The cost of unwarranted SUP in patients with low risk of stress ulcer gastrointestinal bleeding is prohibitive. Treatment algorithms or protocols for SUP based on prescribing patterns, hospital formulary restrictions, and cost-analysis should be considered for each institution to guide critical care physicians on the proper use of SUP therapies.

Survey of hospital systems and common serious medication errors

The Institute for Safe Medication Practices and the University of Illinois at Chicago, College of Pharmacy, undertook a hospital survey of medical-surgical hospitals to determine systems-oriented factors that allow the highest level of medication safety. The study incorporated a peer-reviewed and pretested questionnaire, which focused on critical information necessary to yield quality data for comparison. Through analysis, it was shown that over one third of all medication errors reported in the survey involve just six categories--allergies, insulin, heparin, opiates, PCA devices, and potassium concentrates.

Staff attitudes about the use of robots in pharmacy before implementation of a robotic dispensing system

Hospital pharmacy staff members at a Mid-western university medical center were surveyed to determine their attitudes about the use of robots in pharmacy dispensing before a robotic system was implemented. A questionnaire seeking attitudes about the use of robots in pharmacy was distributed to 147 pharmacy staff (pharmacy managers, pharmacist practitioners, pharmacotherapists, pharmacy residents and fellows, pharmacy technicians, and salaried pharmacy students). Attitudinal items were scored on a 5-point scale ranging from very favorable to very unfavorable. The response rate was 75%. Overall, staff expressed favorable attitudes in terms of job security, professional impact, and general robotics orientation. Pharmacy managers and pharmacotherapists were the most likely to report feeling secure about their jobs; pharmacy technicians and salaried pharmacy students were slightly less positive. Favorable attitudes about the professional impact of the robotic system were demonstrated by all groups except pharmacist practitioners and pharmacy technicians. Attitudes about management issues were unfavorable; pharmacist practitioners demonstrated the least favorable attitudes. In general, responses to semantic-differential statements reflected favorable attitudes; where there were differences, pharmacy technicians showed the least positive and pharmacy managers the most positive attitudes. Respondents reported that pharmacist practitioners would be most positively affected and pharmacy technicians most negatively affected by robotic dispensing. Almost half of the respondents who provided general comments indicated that they needed more information about the use of robots. Pharmacy staff had generally favorable attitudes about the use of robots in pharmacy.

Health outcomes variables important to patients in the treatment of erectile dysfunction

PURPOSE

Erectile dysfunction is underreported and the rate of noncompliance with therapy is high. The National Institutes of Health Consensus Conference on Impotence endorsed the need for outcomes research of the various approaches to treatment. The purpose of our exploratory study was to begin that process through identification of erectile dysfunction treatment outcomes variables that are important to men.

MATERIALS AND METHODS

The study format consisted of focus group meetings. The goal of the discussions was to identify variables that are important to men when choosing among and judging the success of treatment modalities for erectile dysfunction. After discussion participants were individually asked to identify the 10 variables that they considered important and rank the 5 most important variables. An importance score reflecting group consensus was calculated for each variable.

RESULTS

Success and negative outcomes were identified as the 2 most important outcomes variables for all treatment modalities. Participants defined success in several ways. The most important measures of success were cure, pleasure and partner satisfaction. Negative outcome was defined as negative consequences associated with treatment.

CONCLUSIONS

The focus group discussion assisted in identifying and defining outcomes variables important to patients with erectile dysfunction. We believe that understanding issues and outcomes important to such patients is necessary to increase compliance with treatment and, thereby, increase the success of treatment of this widespread condition.

Efficacy of 3-hydroxy-3-methylglutaryl coenzyme a reductase inhibitors in the treatment of patients with hypercholesterolemia: a meta-analysis of clinical trials

Recent studies have documented the long-term impact of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors on mortality and morbidity related to coronary heart disease, establishing the link between lowering cholesterol levels and reducing cardiac events. Our study was a comparative literature review and meta-analysis of the efficacy of four HMG-CoA reductase inhibitors-fluvastatin, lovastatin, pravastatin, and simvastatin-used in the treatment of patients with hypercholesterolemia. The data sources for our meta-analysis of the efficacy of these cholesterol-lowering agents were 52 randomized, double-masked clinical trials with at least 25 patients per treatment arm. The results showed all four agents to be effective in reducing blood cholesterol levels. We computed summary efficacy estimates for all published dose strengths for the four agents. Fluvastatin 20 mg/d reduced low-density lipoprotein cholesterol (LDL-C) levels by 21.0% and total cholesterol (total-C) levels by 16.4%; fluvastatin 40 mg/d reduced these levels by 23.1% and 17.7%, respectively. Lovastatin 20 mg/d reduced LDL-C levels by 24.9% and total-C levels by 17.7%; lovastatin 80 mg/d reduced these levels by 39.8% and 29.2%, respectively. Pravastatin 10 mg/d reduced LDL-C levels by 19.3% and total-C levels by 14.0%; pravastatin 80 mg/d reduced these levels by 37.7% and 28.7%, respectively. Simvastatin 2.5 mg/d reduced LDL-C levels by 22.9% and total-C levels by 15.7%; simvastatin 40 mg/d reduced these levels by 40.7% and 29.7%, respectively. The results of our meta-analysis can be used in conjunction with treatment objectives and comparative cost-effectiveness data for these agents to decide appropriate therapeutic alternatives for individual patients.

National survey of once-daily dosing of aminoglycoside antibiotics

To evaluate the scope of once-daily dosing of intravenous aminoglycoside antibiotics, a questionnaire was designed and mailed to a random sample of pharmacy directors at 500 acute care hospitals in the United States. The response rate was 68.4%. Nineteen percent of the respondents reported use of once-daily dosing of aminoglycosides. Affiliation with a pharmacy residency program and the presence of a pharmacokinetic consultation service by the pharmacy department were associated with this practice (p < 0.05). No other statistically significant differences were found. Reported indications, contraindications, and dosing were consistent with those found in the literature. The profession of pharmacy, as demonstrated by pharmacy residency programs and pharmacokinetic consultation services, appears to have been instrumental in implementing this method of dosing aminoglycosides.

ASHP national survey of pharmaceutical services in federal hospitals--1993

The results of a national mail survey of pharmaceutical services in federal hospitals conducted by ASHP from May to July 1993 are reported. Mailing lists were compiled of all Air Force, Army, Navy, Public Health Service, and Department of Veterans Affairs (VA) hospitals, as well as some federal prison hospitals. Questionnaires were mailed to each chief of pharmacy. The adjusted gross population size was 326. The net response rate was 76%. Complete unit dose drug distribution was offered by 85% of respondents, and 83% offered complete, comprehensive i.v. admixture programs. About half of the pharmacies provided decentralized services. Over 99% provided services to ambulatory care patients. A computerized pharmacy system was present in 99% of the departments. More than 95% of hospitals participated in adverse drug reaction, medication error management, and drug-use-evaluation programs. A total of 93% provided drug therapy monitoring, and 89% provided patient education. About 70% provided written documentation of pharmacist interventions in the medical records, and 57% participated in drug research. A total of 42% provided pharmacist-managed drug clinics, 41% participated in drug management of medical emergencies, 30% provided written medication histories, and 30% provided drug therapy management planning. Pharmacokinetic consultations were provided by 64% of departments. About 90% had a well-controlled formulary system and prescribing restrictions. Therapeutic interchange was practiced by 64%. Diversified pharmaceutical services included telephone or mail-in refill services (80%), mail-out pharmaceutical services (58%), and services to long-term-care facilities (49%). A total of 70% of the hospitals were affiliated with a pharmacy school. The first ASHP national survey of pharmaceutical services in federal hospitals showed that comprehensive distributive and clinical services were offered by most of the facilities.

Evaluating the performance of clinical pharmacy faculty: putting the ACCP template to use

The responsibilities of clinical faculty members are often multifaceted and may include direct patient care, didactic and experiential teaching, research, and administrative duties. Specialization, poorly defined standards of care, and lack of direct supervision have traditionally made performance evaluation difficult. We implemented a method to evaluate clinical faculty as they carried out patient care activities using a revised template for the evaluation of a clinical pharmacist developed by the American College of Clinical Pharmacy Clinical Practice Affairs Committee. In addition, it allows individuals to report and evaluate their own performance in the areas of patient care, instructional activity, university and public service, research and scholarly activities, and administrative duties. Teaching evaluations from clerkship students and residents are also submitted and assessed during the annual interview. To determine the usefulness of the evaluation, including the template, we surveyed the opinions of clinical faculty (nontenured) at four primary practice sites (response rate 92%). Mean scores for responses suggested agreement with statements as to the merits of the evaluation system; however, there was some variation among practice sites. Incorporating the template into a broad evaluation system was effective in facilitating improved job performance and career development. Adaptation of the template may be practice site dependent and should be coordinated by a participative approach. Additional assessment may be facilitated by physician, nurse, or peer evaluation.
