Pharmacy-based CLIA-waived testing in the United States: Trends, impact, and the road ahead

BACKGROUND

Federal authorization of the use of Clinical Laboratory Improvement Amendments of 1988 (CLIA) waived point-of-care tests for SARS-CoV-2 by pharmacists during the pandemic resulted in a dramatic rise in the number of community pharmacies that became CLIA-waived test sites. Now as we exit the pandemic, the wide-ranging expansion of the scope of practice facilitated currently by the PREP Act is set to expire in fall 2024. As a result, American pharmacists' ability to offer CLIA-waived testing services will revert to a patchwork of state laws.

OBJECTIVE

This study aims to examine both the number of pharmacies in the United States with CLIA Certificates of Waiver before and after the SARS-CoV-2 pandemic and the state-by-state differences in the percentage of pharmacies with CLIA Certificates of Waiver.

METHODS

Data were collected from the U.S. Centers for Disease Control and Prevention CLIA Laboratory Search website on May 3rd, 2015, August 4th, 2019, November 26th, 2020, October 6th, 2021, November 23rd, 2022, and December 4th, 2023. The website allows for the exportation of demographic data on all CLIA-waived facilities by state.

RESULTS

The total number of pharmacies with a CLIA-waiver grew from 10,626 (17.9%) locations in 2015 to 12,157 (21.4%) locations in 2019, to 15,671 (27.6%) locations in 2020, and to 29,011 (51.6%) locations in 2023. States demonstrated considerable variability in the percentage of pharmacies possessing a CLIA certificate of waiver in 2023, with a range of 10.7%-87.9%.

CONCLUSIONS

Use of CLIA-waived tests in pharmacies has grown by 140% since 2019. The time period from 2019 to 2021 witnessed a 92.5% increase in pharmacies that possessed a certificate of waiver which was largely driven by the pandemic. Interestingly, from 2021 to 2023 the was continued growth in the market of 31.6%. This suggests that pharmacies continue to see opportunity in offering CLIA-waived testing services beyond those that had been extended as a result of the pandemic.

Initial Employment Plans of PharmD Graduates from Ten Public Colleges/Schools of Pharmacy, 2018-2022

OBJECTIVE

Since 2009, the Big Ten Pharmacy Assessment Collaborative has surveyed their Doctor of Pharmacy (PharmD) graduates regarding their first employment plans. The current study updates the results from 2013-2017, since which the nationwide demand for pharmacists decreased, then increased again due to COVID-19.

METHODS

Quantitative first-position employment data from 2018-2022 were tracked among 6687 Big Ten PharmD graduates. Outcomes included job/residency/fellowship placement; satisfaction with placement; salary; time spent searching; and perceived difficulty finding placement.

RESULTS

Over the study period, 5276 usable surveys were received (survey participation rate 79%). Respondents who reported applying for employment (2699) spent nearly 3 months searching for a position, although 64% had received employment offers before graduation. Annual salaries in pharmacy positions of at least 32 h per week (excluding residencies or fellowships) trended downward from $113,754 in 2018 to $99,175 in 2021, rebounding to $114,097 in 2022. Approximately 42% of respondents who applied for jobs reported difficulty finding a position in 2018 and 2019, decreasing to 20% in 2022. In total, 73% of respondents were satisfied with the offers they received, with 72% finding positions in their preferred job setting. An average of 57% applied for residencies from 2018 to 2022, nearly 10% higher than 2013-2017, with 76% of applicants matching. An additional 19% planned to pursue additional academic degrees, fellowship training, or both.

CONCLUSION

From 2018 to 2022, Big Ten PharmD graduates found pharmacy-related first positions to the same extent as did Big Ten PharmD graduates from 2013-2017, at similar salaries.

COVID-19 host genetic risk study conducted at community pharmacies: Implications for public health, research and pharmacists' scope of practice

Community pharmacists serve a large, diverse population of patients, resulting in the potential to utilize community pharmacies as recruitment sites for clinical research. Beyond traditional roles as one of the most accessible health care professionals in the US healthcare system, pharmacists have played a major role in the response to the COVID-19 pandemic, administering hundreds of thousands of vaccines and tests. However, less emphasis is placed on the ability to leverage community pharmacies as research-focused partners for clinical studies. In this study, we demonstrate the feasibility and workflow of recruiting study participants from community pharmacies and confirm genetic markers of COVID-19 susceptibility. Specific genetic markers include those associated with COVID-19 infection risk (ACE2, TMEM27, and RAVER1), difficulty breathing (NOTCH4), and hospitalization (OAS3). In addition, collaboration with a clinical laboratory allowed for a more seamless consenting process without substantial training needs or workflow disruption at the community pharmacy site. The COVID-19 pandemic has demonstrated that the expansion of pharmacists' scope of practice is a key factor in managing the population health crisis; this study demonstrates that pharmacies can also advance clinical research studies by serving as sites for patient recruitment from a large, diverse, and ambulatory study population.

Time and motion study of hepatitis C virus point-of-care testing in community pharmacies

BACKGROUND

Point-of-care (POC) testing for hepatitis C virus (HCV) is readily available for implementation in community pharmacies, but it is unknown how feasible administration of the tests would be in the current community pharmacy model.

OBJECTIVE

The primary objective of this study was to describe time associated with each step in a pharmacy HCV screening program and compare the results to influenza management in the pharmacy workflow.

METHODS

For this time and motion study, the process was broken into 10 categories. A standardized patient was used for each location to accurately assess and compare the integration of HCV testing in the various workflows. Data were collected for each category during 2 random visits at each of 6 community pharmacies. Times were averaged, and a standard deviation calculated for each specific category. The data were then compared to previous time-in-motion values collected for influenza management.

RESULTS

The average total time (patient identification to completion of visit) to complete the HCV POC test was 59 minutes 44 seconds (+/- 9:23). The average time that pharmacists and technicians actively spent with each patient was 10 minutes 23 seconds and 11 minutes 20 seconds, respectively. The average labor cost per patient for pharmacists and technicians were $11.55 and $3.75, respectively.

CONCLUSION

The hands-on time requirements and workflow associated with offering HCV screening in a pharmacy using the Oraquick HCV rapid antibody test were similar to those noted with other pharmacy based POC testing services. Labor costs could be lessened by delegation of some non-clinical functions to a qualified pharmacy technician. We suggest an HCV rapid antibody test can be incorporated into pharmacy workflow with reasonable efficiency.

Implementation and Evaluation of a Collaborative, Pharmacy-Based Hepatitis C and HIV Screening Program

INTRODUCTION

Pharmacy-based HIV and hepatitis C virus (HCV) screening services developed in conjunction with state and local health departments can improve public health through increased access to testing and a linkage-to-care strategy. The objective of this study was to evaluate the impact of implementing HIV and HCV screening in community pharmacies.

METHODS

This prospective, multicenter implementation project was conducted from July 2015 through August 2018. Sixty-one pharmacies participated in 3 US regions. We assessed the effectiveness of point-of-care testing, counseling, and disease education for populations at increased risk for HIV and HCV infection through screening programs offered in community pharmacies. Pharmacy customers were offered screening with point-of-care HIV and/or HCV tests. Reactive test results were reported to state or local health departments for disease surveillance.

RESULTS

A total of 1,164 patients were screened for HIV, HCV, or both at the 61 participating pharmacies; the average number of patients screened per pharmacy was 19. Pharmacists conducted 1,479 HIV or HCV tests among the 1,164 patients. Five of 612 (0.8%) HIV tests yielded a reactive result, and 181 of 867 (20.9%) of HCV tests yielded a reactive result.

CONCLUSION

Patients at increased risk of HIV or HCV can benefit from screening for infection at community pharmacies. Ease of accessibility to testing coupled with a strategy for linkage to care designed for the local community can improve patient care and improve the course of treatment for HIV and HCV.

Implementing community pharmacy-based influenza point-of-care test-and-treat under collaborative practice agreement

Background

Early and accessible testing for influenza with point-of-care testing (POCT) can be a critical factor for deciding to begin antiviral treatment. More than 10,000 pharmacies across the USA offer Clinical Laboratory Improvement Amendments-waived POCT for infectious diseases, such as influenza A/B. Knowledge of barriers and facilitators to large-scale POCT implementation may be useful in scaling POCT for influenza test-and-treat services (Flu POCT). The objective of this study was to explore the experiences of pharmacists who were early adopters of Flu POCT and treatment under collaborative practice agreement in community pharmacy settings.

Methods

Qualitative research design with in-depth, semi-structured virtual video interviews of licensed US community pharmacists. Interview questions were derived from the Consolidated Framework for Implementation Research (CFIR). Interviewees were selected via a purposeful sampling of pharmacists who were enrolled in a nationwide clinical trial involving pharmacy-based influenza test-and-treat under a collaborative agreement. Interviews were recorded and transcribed. A deductive analytic approach was used via constructs from the CFIR.

Results

Six pharmacists were interviewed. Interviews ranged from 28 to 70 min, with an average length of 46 min. Four broad themes emerged from the data, and each had corresponding subthemes and supporting quotes: influence of the Flu POCT service characteristics on pharmacy implementation, influence of factors outside of the pharmacy setting in Flu POCT implementation, factors within the pharmacy setting influencing implementation, and process of implementing Flu POCT. A novel pharmacy-based Flu POCT implementation framework is presented.

Conclusions

Implementation of community pharmacy-based Flu POCT services is feasible; but, a thorough understanding of both barriers and facilitators to their implementation is needed to increase the spread and scale of these programs. Specifically, pharmacy stakeholders should focus efforts on increasing patient and provider awareness, pharmacist acceptance, leadership support, and support of health providers external to the pharmacy to improve implementation success.

Integrating and Disseminating Pre-Exposure Prophylaxis (PrEP) Screening and Dispensing for Black Men Who Have Sex With Men in Atlanta, Georgia: Protocol for Community Pharmacies

BACKGROUND

Black men who have sex with men (BMSM) suffer from alarmingly high rates of HIV in the United States. Pre-exposure prophylaxis (PrEP) can reduce the risk of HIV infection by 99% among men who have sex with men, yet profound racial disparities in the uptake of PrEP persist. Low PrEP uptake in BMSM is driven by poor access to PrEP, including inconvenient locations of PrEP-prescribing physicians, distrust of physicians, and stigma, which limit communication about PrEP and its side effects. Previous work indicates that offering HIV prevention services in pharmacies located in low-income, underserved neighborhoods is feasible and can reduce stigma because pharmacies offer a host of less stigmatized health services (eg, vaccinations). We present a protocol for a pharmacy PrEP model that seeks to address challenges and barriers to pharmacy-based PrEP specifically for BMSM.

OBJECTIVE

We aim to develop a sustainable pharmacy PrEP delivery model for BMSM that can be implemented to increase PrEP access in low-income, underserved neighborhoods.

METHODS

This study design is a pilot intervention to test a pharmacy PrEP delivery model among pharmacy staff and BMSM. We will examine the PrEP delivery model's feasibility, acceptability, and safety and gather early evidence of its impact and cost with respect to PrEP uptake. A mixed-methods approach will be performed, including three study phases: (1) a completed formative phase with qualitative interviews from key stakeholders; (2) a completed transitional pilot phase to assess customer eligibility and willingness to receive PrEP in pharmacies during COVID-19; and (3) a planned pilot intervention phase which will test the delivery model in 2 Atlanta pharmacies in low-income, underserved neighborhoods.

RESULTS

Data from the formative phase showed strong support of pharmacy-based PrEP delivery among BMSM, pharmacists, and pharmacy staff. Important factors were identified to facilitate the implementation of PrEP screening and dissemination in pharmacies. During the transitional pilot phase, we identified 81 individuals who would have been eligible for the pilot phase.

CONCLUSIONS

Pharmacies have proven to be a feasible source for offering PrEP for White men who have sex with men but have failed to reach the most at-risk, vulnerable population (ie, BMSM). Increasing PrEP access and uptake will reduce HIV incidence and racial inequities in HIV. Translational studies are required to build further evidence and scale pharmacy-based PrEP services specifically for populations that are disconnected from HIV prevention resources.

Pharmacy-Based Point-of-Care Testing: How a “Standard of Care” Approach Can Facilitate Sustainability

COVID-19 spurred rapid expansion of pharmacy-based point-of-care testing (POCT). This growth was aided, in part, by federal guidance that removed state-level regulatory uncertainty surrounding the ability of pharmacists to administer, interpret, and act on the results of tests. Surveys suggest there is considerable confusion about the legality of these services by state regulators. To ensure the sustainability of POCT services over time, states should consider adopting a standard of care approach to regulation, allowing a flexible framework for practice innovation and expansion over time.

Short-term cost-effectiveness of oral semaglutide for the treatment of type 2 diabetes mellitus in the United States

BACKGROUND: Oral semaglutide is the first orally administered glucagon-like peptide-1 receptor agonist (GLP-1RA) approved by the FDA. Clinical trials found that oral semaglutide 14 mg had a greater reduction in hemoglobin A1c (A1c) compared with empagliflozin 25 mg and sitagliptin 100 mg and was noninferior to liraglutide 1.8 mg. However, US cost-effectiveness data for oral semaglutide are limited and do not consider the costs of adverse events. OBJECTIVE: To assess the short-term cost-effectiveness of oral semaglutide compared with empagliflozin, sitagliptin, and liraglutide in patients with type 2 diabetes. METHODS: A decision analysis over a 52-week time horizon was used to evaluate the incremental cost-effectiveness of oral semaglutide vs empagliflozin, sitagliptin, and liraglutide from a US health care payer's perspective. Data on efficacy, adverse events, and discontinuation were derived from 52-week data from phase 3, head-to-head clinical trials (PIONEER 2, 3, and 4). Costs included drug and administration cost and treatment of gastrointestinal adverse events. Incremental cost-effectiveness ratios (ICERs) were calculated as the difference in cost over the difference in A1c reduction between oral semaglutide and comparators. RESULTS: In the base-case analysis, 52-week treatment costs with oral semaglutide were $2,660 and $3,104 higher and $2,337 less than empagliflozin, sitagliptin, and liraglutide, respectively. Incremental (greater) A1c reductions were seen with oral semaglutide at 0.40%, 0.50%, and 0.30% vs empagliflozin, sitagliptin, and liraglutide, respectively. ICERs per 1% reduction in A1c for oral semaglutide were $6,650 and $6,207 vs empagliflozin and sitagliptin, respectively. Oral semaglutide was dominant vs liraglutide (ICER of -$7,790). CONCLUSIONS: Oral semaglutide was dominant relative to liraglutide, offering a cost-saving GLP-1RA oral alternative. While there is not a recognized willingness-to-pay threshold for a 1% reduction in A1c, oral semaglutide may be cost-effective relative to empagliflozin and sitagliptin if a decision maker's willingness-to-pay threshold exceeds $6,650 and $6,207, respectively. DISCLOSURES: No outside funding supported this study. The authors have no conflicts of interest to declare.

The impact of the COVID-19 pandemic on addressing common barriers to pharmacy-based point-of-care testing

Introduction: Pharmacy-based point-of-care testing has long had the potential to improve patient access to timely care, but adoption has been slowed by financial and regulatory barriers. The COVID-19 pandemic reduced or temporarily eliminated many of the barriers to pharmacy-based testing. This review examines how the changes brought on by may impact pharmacy-based testing after the pandemic.Areas covered: This review searched peer-reviewed, lay, and regulatory literature to explore the implementation of pharmacy-based COVID-19 testing. This includes a review of regulatory and financial changes that removed barriers to testing. Additionally, it reviews the literature related to the growth of pharmacy-based testing.Expert opinion: It is clear that the COVID-19 pandemic created an awareness and opportunity for pharmacy-based point-of-care testing. The changes made in response to the pandemic have the potential to increase the role of pharmacy-based testing, but additional regulatory changes and wider pharmacy adoption are still needed to maximize the value of such services.

Impact of COVID-19 on prevalence of community pharmacies as CLIA-Waived facilities

Background

The Clinical Laboratory Improvement Amendments of 1988 (CLIA) enabled greater access to low-risk tests by allowing their use in facilities with a Certificate of Waiver in the U.S. Recently, the 2019 novel coronavirus (COVID-19) pandemic has shined a spotlight on CLIA-waived diagnostic testing. To meet this increased patient demand for diagnostic testing, the U.S. Department of Health and Human Services (HHS) authorized licensed pharmacists to order and administer FDA authorized COVID-19 tests.

Objective

This study aims to update the previous national benching report and examine both the number of pharmacies in the United States with CLIA Certificates of Waiver before and after the SARS-CoV-2 pandemic and the state-by-state differences in the percentage of pharmacies with CLIA Certificates of Waiver.

Methods

Data were collected from the U.S. Centers for Disease Control and Prevention CLIA Laboratory Search website May 3rd, 2015, August 4th, 2019 and November 26th, 2020. The website allows for exportation of demographic data on all CLIA-waived facilities by state.

Results

Pharmacies exhibited the largest growth both in number (4865 new locations) and by percent (45%) of CLIA-waived facilities between 2015 and 2020. The total number of pharmacies with a CLIA-waiver grew from 10,626 (17.94%) locations in 2015 to 12,157 (21.43%) locations in 2019, to 15,671 (27.63%) locations in 2020. States demonstrated considerable variability in the percentage of pharmacies with a CLIA-waiver, with a range of 2.92%–56.52%.

Conclusions

Pharmacies have become an increasingly important location for patients to access CLIA-waived tests in the United States, now serving as the second largest provider of CLIA-waived tests by the total number of locations. Most of this growth occurred between 2019 and 2020 due to the COVID-19 pandemic, and concentrated efforts will be necessary to sustain this momentum.

The Impact of Eliminating Backward Navigation on Computerized Examination Scores and Completion Time

Objective. To determine whether elimination of backward navigation during an examination resulted in changes in examination score or time to complete the examination.Methods. Student performance on six examinations in which backward navigation was eliminated was compared to performance on examinations administered to pharmacy students the previous year when backwards navigation was allowed. The primary comparison of interest was change in student performance on a subset of identical questions included on both examinations. Secondary outcomes included change in total examination score and completion time.Results. No significant reduction in examination scores was observed as a result of eliminating backward navigation. The average time that students spent on a question was significantly reduced on two of the six examinations.Conclusion. Restricting pharmacy students' ability to revisit questions previously answered (elimination of backward navigation) on an examination had no adverse effect on scores or testing time when assessed across three years of the didactic pharmacy curriculum.

Support and perceived barriers to implementing pre-exposure prophylaxis screening and dispensing in pharmacies: Examining concordance between pharmacy technicians and pharmacists

OBJECTIVES

Recent legislation to expand pre-exposure prophylaxis (PrEP) screening and dispensing in pharmacies may significantly improve PrEP access for people at a high risk of human immunodeficiency virus (HIV) transmission. Studies have shown that pharmacists show wide support for PrEP expansion in pharmacies. However, pharmacy technicians are often the first point of contact for patients in pharmacies and are required to implement many of the tasks to ensure patients of a pharmacy receive adequate services. The purpose of this study was to assess pharmacists' and pharmacy technicians' perspectives regarding the implementation of PrEP screening and dispensing.

METHODS

We qualitatively examined whether pharmacy technicians' (n = 6) support and perceived barriers to screening and dispensing PrEP in pharmacies were concordant with those of pharmacists (n = 7). Pharmacy staff were recruited from high-risk HIV neighborhoods in Atlanta, GA using AIDSVu (Atlanta, GA). Two independent coders used MAXQDA (Berlin, Germany) and performed thematic data analysis and unitization to determine agreement.

RESULTS

Pharmacists and pharmacy technicians expressed strong willingness and support for screening and dispensing PrEP in pharmacies. Both groups expressed concerns about the time and the resources needed to perform PrEP screening and dispensing. Technicians, however, also reported concerns about privacy for patients, the need for community support and awareness of pharmacy-based PrEP screening, and recommended scheduling of PrEP screening activities during a limited part of the day to facilitate screening. Pharmacists reported fewer barriers but reported a need for more training of pharmacy staff to assist with PrEP screening and dispensing implementation.

CONCLUSION

Pharmacy technicians discussed more barriers compared with pharmacists who were largely centered around practical considerations (i.e., logistics and workflow) that may affect the success of PrEP screening and dispensing. Given technicians' pivotal role in the pharmacy, implementation of pharmacy-based PrEP services should address technicians' perceived barriers in addition to those of pharmacists.

Predictors of vaccination rates in people living with HIV followed at a specialty care clinic

People Living with HIV (PLWH) remain disproportionately susceptible to vaccine-preventable illnesses due to increased morbidity and mortality from common pathogens, increased transmission related to epidemiologic factors, and decreased vaccination rates. We aimed to describe patient-specific predictive factors that may impact adherence to the CDC's recommended vaccination schedules in PLWH. We retrospectively evaluated adult PLWH in care at the University of Nebraska Medical Center's HIV clinic and collected information related to demographics, clinic visits, vaccination status, and measures of HIV disease control. Patients were categorized as "Adherent" if they had received all vaccinations for which they were eligible and were categorized as "Non-Adherent" if they were deficient or delayed in receiving one or more vaccinations. Participant characteristics were compared between groups by multivariable logistic regression to identify predictors associated with vaccine schedule non-adherence. We evaluated 502 PLWH who met our inclusion criteria; 206 of these (41%) had received all eligible vaccinations, while 296 (59%) were missing one or more vaccinations. The mean age of participants was 48 years old, 76% were male, and 53% were white. Our participants had a median of 2.83 clinic visits per year and missed 8.3% of scheduled clinic visits. Factors associated with non-adherence to vaccination schedules included a high frequency of missed clinic appointments (>10%), men who have sex with men, and a CD4 count <200 cells/mm³. Knowledge of variables associated with vaccination rates may be beneficial in identifying patients at-risk for under-vaccination and designing targeted education programs for providers and patients.

Pharmacy-Based Infectious Disease Management Programs Incorporating CLIA-Waived Point-of-Care Tests

There are roughly 48,000 deaths caused by influenza annually and an estimated 200,000 people who have undiagnosed human immunodeficiency virus (HIV). These are examples of acute and chronic illnesses that can be identified by employing a CLIA-waived test. Pharmacies across the country have been incorporating CLIA-waived point-of-care tests (POCT) into disease screening and management programs offered in the pharmacy. The rationale behind these programs is discussed. Additionally, a summary of clinical data for some of these programs in the infectious disease arena is provided. Finally, we discuss the future potential for CLIA-waived POCT-based programs in community pharmacies.

Evaluation of a community pharmacy-based influenza and group A streptococcal pharyngitis disease management program using polymerase chain reaction point-of-care testing

OBJECTIVES

The purpose of this study was to demonstrate the feasibility of implementing a Clinical Laboratory Improvement Amendments-waived real-time polymerase chain reaction (PCR) molecular test into a community pharmacy setting as part of a collaborative influenza and group A Streptococcus (GAS) disease management program.

SETTING AND PARTICIPANTS

Two community pharmacy sites in Tennessee.

PRACTICE DESCRIPTION

Patients presenting to the pharmacy with symptoms consistent with influenza or GAS from November 1, 2016, to April 30, 2018.

PRACTICE INNOVATION

Influenza and GAS management programs based on previously developed protocols occurred at 2 community pharmacies in Tennessee. Pharmacies used the Cobas Liat testing system (Roche Diagnostics). Based on test results and under a collaborative practice agreement, pharmacists dispensed prescription medications for patients with a positive test: oseltamivir for influenza and amoxicillin for GAS. Patients with negative tests were treated with over-the-counter (OTC) medications or referred. Patients testing negative for GAS were asked to consent to having a second throat swab sent for culture.

EVALUATION

Number of patients tested, point-of-care test results, and treatment received.

RESULTS

Two hundred and two patients received care at the 2 pharmacies (116 for influenza, 46 for GAS, and 43 for both). Sixty (38%) tested positive for influenza, with 51 receiving an antiviral prescription, and 16 (18%) tested positive and were treated for GAS. No patient testing negative for either or positive for influenza was dispensed an antibiotic. For patients consenting to a follow-up culture, all GAS cultures sent for confirmatory testing were negative.

CONCLUSION

A protocol-driven community pharmacy-based disease management program using real-time PCR testing for influenza and GAS was able to offer appropriate treatment to patients without overuse of antibiotics.

Acceptability and feasibility of a pharmacist-led HIV pre-exposure prophylaxis (PrEP) program in the Midwestern United States

Background

Human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) substantially reduces the risk of HIV acquisition, yet significant barriers exist to its prescription and use. Incorporating pharmacists in the PrEP care process may help increase access to PrEP services.

Methods

Our pharmacist-led PrEP program (P-PrEP) included pharmacists from a university-based HIV clinic, a community pharmacy, and 2 community-based clinics. Through a collaborative practice agreement, pharmacists conducted PrEP visits with potential candidates for PrEP, according to the recommended Centers for Disease Control and Prevention guidelines, and authorized emtricitabine-tenofovir disoproxil fumarate prescriptions. Demographics and retention in care over 12 months were summarized, and participant satisfaction and pharmacist acceptability with the P-PrEP program were assessed by Likert-scale questionnaires.

Results

Sixty patients enrolled in the P-PrEP program between January and June 2017 completing 139 visits. The mean age was 34 years (range, 20–61 years), and 88% identified as men who have sex with men, 91.7% were men, 83.3% were white, 80% were commercially insured, and 89.8% had completed some college education or higher. Participant retention at 3, 6, 9, and 12 months was 73%, 58%, 43%, and 28%, respectively. To date, no participant has seroconverted. One hundred percent of the participants who completed the patient satisfaction questionnaire would recommend the P-PrEP program. Pharmacists reported feeling comfortable performing point-of-care testing and rarely reported feeling uncomfortable during PrEP visits (3 occasions, 2.2%) or experiencing workflow disruption (1 occasion, 0.7%).

Conclusions

Implementation of a pharmacist-led PrEP program is feasible and associated with high rates of patient satisfaction and pharmacist acceptability.

Predictors and Costs of 30-Day Readmissions After Index Hospitalizations for Alcohol-Related Disorders in U.S. Adults

BACKGROUND

In 2015, the Hospital Readmissions Reduction Program mandated financial penalties to hospitals with greater rates of readmissions for certain conditions. Alcohol-related disorders (ARD) are the fourth leading cause of 30-day readmissions. Yet, there is a dearth of national-level research to identify high-risk patient populations and predictors of 30-day readmission. This study examined patient- and hospital-level predictors for index hospitalizations with principal diagnosis of ARD and predicted the cost of 30-day readmissions.

METHODS

The 2014 Nationwide Readmissions Database was used to identify ARD-related index hospitalizations. Multivariable logistic regression was used to estimate patient- and hospital-level predictors for readmissions, and a 2-part model was used to predict the incremental cost conditional upon readmission.

RESULTS

In 2014, 285,767 index hospitalizations for ARD were recorded, and 18.9% of ARD-associated hospitalizations resulted in at least one 30-day readmission. Patients who were males, aged 45 to 64 years, Medicaid enrollees, living in urban and low-income areas, or with 1 to 2 comorbidities had high risk of readmission. Index hospitalization costs were higher among readmitted patients ($8,840 vs. $8,036, p < 0.01). Predicted mean costs for readmissions on index stay with ARD were greater among those aged 45 to 64 years ($1,908, p < 0.001), Medicare enrollees ($2,133, p < 0.001), rural residents ($1,841, p < 0.01), living in high-income areas ($1,876, p < 0.001), with 4 or more comorbidities ($2,415, p < 0.001), or admitted in large metropolitan hospitals ($2,032, p < 0.001), with large number of beds ($1,964, p < 0.001), with government ownership ($2,109, p < 0.001), or with low volume of ARD cases ($2,155, p < 0.001).

CONCLUSIONS

One in 5 ARD-related index hospitalizations resulted in a 30-day readmission. Overall, costs of index hospitalizations for ARD were $2.3 billion, of which $512 million were spent on hospitalizations that resulted in at least 1 readmission. There is a need to develop patient-centric health programs to reduce readmission rates and costs among ARD patients.

Midwest pharmacists' familiarity, experience, and willingness to provide pre-exposure prophylaxis (PrEP) for HIV

Introduction

Pharmacist provision of pre-exposure prophylaxis (PrEP) through collaborative practice agreements with physicians could expand access to people at risk for HIV. We characterized pharmacists’ familiarity with and willingness to provide PrEP services in Nebraska and Iowa.

Methods

An invitation to complete an 18-question survey was emailed to 1,140 pharmacists in Nebraska and Iowa in June and July of 2016. Descriptive analyses and Pearson chi-square tests were used to determine to what extent demographics, familiarity and experience were associated with respondent willingness to provide PrEP. Wilcoxon rank-sum tests compared ages and years of experience between groups of respondents.

Results

One hundred forty pharmacists (12.3%) responded. Less than half were familiar with the use of PrEP (42%) or the CDC guidelines for its use (25%). Respondents who were older (p = .015) and in practice longer (p = .005) were less likely to be familiar with PrEP. Overall, 54% indicated they were fairly or very likely to provide PrEP services as part of a collaborative practice agreement and after additional training. While familiarity with PrEP use or guidelines did not affect respondents’ willingness to provide PrEP, respondents were more likely to provide PrEP with prior experience counseling HIV-infected patients on antiretroviral therapy (OR 2.43; p = 0.023) or PrEP (OR 4.67; p = 0.013), and with prior HIV-related continuing education (OR 2.77; p = 0.032).

Conclusions

Pharmacist respondents in Nebraska and Iowa had limited familiarity and experience with PrEP, but most indicated willingness to provide PrEP through collaborative practice agreements after additional training. Provision of PrEP-focused continuing education may lead to increased willingness to participate in PrEP programs.

Pharmacist-Provided Pharmacogenetic Point-of-Care Testing Consultation Service: A Time and Motion Study

Background: With recent advances in pharmacogenomics (PGx) comes the potential to customize medication use based on genetic data. Support for PGx has found practical limitations in terms of workflow and turnaround time of a test. However, with the expansion of point-of-care testing (POCT) in pharmacy practice models comes opportunity for PGx testing in the pharmacy setting. Objective: The purpose of this study is to quantify the amount of time spent during each step of a PGx POCT encounter in a community pharmacy setting. Methods: A time and motion study was conducted using a mock community pharmacy space for a simulated PGx-focused encounter to manage antiplatelet therapy following hospital discharge. PGx POCT was conducted using the Spartan RX instrument. Simulated patient encounters were divided into 7 categories. Time spent in each step, as well as total time spent, was tracked. Results: A total of 54 simulated PGx POCT encounters took place with an average time of 9.49 minutes (SD ± 1.38 minutes). Instrument run time adds 60 minutes to the total time required to obtain a result. Duties that could be performed by an appropriately trained pharmacy technician totaled 6.86 minutes. Conclusions: PGx POCT would require 9.49 minutes of pharmacy staff hands-on time for the encounter, which could be reduced to 2.64 minutes of pharmacist time with appropriate pharmacy technician involvement. Time requirements for PGx POCT are similar to that of community pharmacy-based immunizations. Future studies could explore how practice could change if PGx testing were routinely performed in the pharmacy.

Observation of a Pharmacist-Conducted Group A Streptococcal Pharyngitis Point-of-Care Test: A Time and Motion Study

BACKGROUND

Acute pharyngitis is among the most common infectious diseases encountered in the United States, resulting in 13 million patient visits annually, with group A streptococcus (GAS) being a common causative pathogen. It is estimated that annual expenditures for the treatment of adult pharyngitis will exceed US$1.2 billion annually. This substantial projection reinforces the need to evaluate diagnosis and treatment of adult pharyngitis in nontraditional settings.

OBJECTIVE

The objective of this research is to quantify the amount of pharmacist time required to complete a point-of-care (POC) test for a patient presenting with pharyngitis symptoms.

METHODS

A standardized patient with pharyngitis symptoms visited 11 pharmacies for POC testing services for a total of 33 patient encounters. An observer was present at each encounter and recorded the total encounter time, divided into 9 categories. Pharmacists conducted POC testing in 1 of 2 ways: sequence 1-pharmacists performed all service-related tasks; sequence 2-both pharmacists and pharmacist interns performed service-related tasks.

RESULTS

The average time for completion of a POC test for GAS pharyngitis was 25.3 ± 4.8 minutes. The average pharmacist participation time per encounter was 12.7 ± 3.0 minutes (sequence 1), which decreased to 2.6 ± 1.1 minutes when pharmacist interns were involved in the testing (sequence 2).

CONCLUSION

Although additional studies are required to further assess service feasibility, this study indicates that a GAS POC testing service could be implemented in a community pharmacy with limited disruption or change to workflow and staff.

Effectiveness of a pharmacist-physician collaborative program to manage influenza-like illness

OBJECTIVES

To examine the effectiveness of collaborative physician-community pharmacist programs to treat influenza-like illness (ILI) with respect to clinical outcomes and health care utilization.

DESIGN

Prospective multicenter cohort study.

SETTING

Fifty-five pharmacies in Michigan, Minnesota, and Nebraska.

PATIENTS

Adult patients presenting to the pharmacy with ILI during the 2013-14 influenza season (October 1, 2013 to May 30, 2014).

INTERVENTION

Pharmacists screened adult patients presenting with ILI, completed a brief physical assessment, performed a point-of-care rapid influenza diagnostic test (RIDT), and provided appropriate referral or treatment per an established collaborative practice agreement (CPA) with a licensed prescriber. Pharmacists followed-up with patients 24 to 48 hours after the encounter to assess patient status and possible need for further intervention.

MAIN OUTCOME MEASURES

Number of patients screened, tested, and treated for influenza.

RESULTS

Of the 121 patients screened, 45 (37%) were excluded and referred to their primary care provider or an urgent care facility for management. Of the 75 patients (62%) eligible for participation, 8 (11%) had a positive RIDT and were managed according to the CPA. Of the patients tested, 34.6% had no primary care physician and 38.7% visited the pharmacy outside of normal office hours. Only 3% of patients reported feeling worse at follow-up.

CONCLUSION

This study describes a physician-pharmacist collaborative model for treating ILI. Using an evidence-based CPA, pharmacists were able to provide timely treatment to patients with and without influenza.

Utilization of influenza and streptococcal pharyngitis point-of-care testing in the community pharmacy practice setting

BACKGROUND

One way to reduce the complications and costs of influenza like illness and pharyngitis is to improve access to testing and treatment in early stages of infection. Pharmacy-based screening and treatment of group A streptococcus (GAS) infection and influenza has the potential to improve patient care and population health.

OBJECTIVE

To improve patient care and population health, the objective of this retrospective study was to assess if a previously validated service model could be implemented by pharmacy chains without mandated standardization.

METHODS

Researchers utilized a certificate program to provide initial training to pharmacists and shared templates from previous validated models. Pharmacy companies were responsible for navigation of all implementation within their company. Researchers analyzed the de-identified data from patients seeking point-of-care testing from the participating pharmacies.

RESULTS

Participating pharmacies reported 661 visits for adult (age 18 and over) patients tested for influenza for GAS pharyngitis. For the GAS patients, 91 (16.9%) tested positive. For the Influenza patients, 22.9% tested positive and 64 (77.1%) testing negative. Access to care was improved as patients presented to the visit outside normal clinic hours for 38% of the pharmacy visits, and 53.7% did not have a primary care provider.

CONCLUSION

A collaborative care model for managing patients with symptoms consistent with influenza or group A streptococcus can be successfully implemented, and improve access to care outside of normal clinic hours and for those without a regular primary care provider.

Community pharmacist-physician collaborative streptococcal pharyngitis management program

OBJECTIVES

To describe patient outcomes associated with a community pharmacy-based, collaborative physician-pharmacist group A Streptococcus (GAS) management program.

SETTING

Fifty-five chain and independent community pharmacies in Michigan, Minnesota, and Nebraska.

PRACTICE INNOVATION

Pharmacists screened clinically stable adult patients who presented with signs and symptoms consistent with GAS pharyngitis from October 1, 2013, to August 1, 2014, by means of Centor criteria, and performed a physical assessment followed by a rapid antigen detection test (RADT) for eligible patients. Patients were treated according to a collaborative practice agreement (CPA) with a licensed prescriber or a physician consult site model. Pharmacists followed up with patients 24-48 hours after the encounter to assess patient status and possible need for further intervention.

EVALUATION

Number of patients screened, tested, and treated, and health care utilization.

RESULTS

Of 316 patients screened, 43 (13.6%) were excluded and referred for care. Of 273 patients (86.4%) eligible for testing, 48 (17.6%) had positive test results and 46 (16.8%) received amoxicillin or azithromycin per the CPA. Of those tested, 43.2% had no primary provider and 43.9% visited the pharmacy outside of traditional clinic office hours.

CONCLUSION

Pharmacists demonstrated the ability and capacity to provide care for patients seeking treatment for pharyngitis. The number of patients without a primary care provider and seen at the pharmacy outside of normal office hours highlights the improved access that community pharmacy-based care offers.

Description of the methods for describing and assessing the appropriateness of antibiotic prescribing and adherence to published treatment guidelines in an academic medical clinic

Overuse and inappropriate use of antibiotics have been associated with increased rates of antimicrobial resistance and increased healthcare expenditures. Tracking inpatient antimicrobial use has helped quantify the value of stewardship programs aimed at improving the rational use of antibiotics among hospitalized patients. Unfortunately, similar methods for tracking and assessing antibiotic use in the outpatient setting have not been well described. We developed a novel method to capture trends and assess appropriateness of antibiotic usage. This strategy is based on identification of antimicrobial prescriptions in an electronic medical record system, linking prescribing to patient data, and capturing information regarding dosing and indications for use. Using information on dose, frequency, and duration of the antibiotic prescribed, a parameter to quantify antibiotic exposure (Prescribed Therapeutic Regimen, PTR) is calculated. This parameter is compared to a database of information on agents recommended in published guidelines (Recommended Therapeutic Regimen, RTR). By linking an ICD-9 code and the prescribed antibiotic we determine the appropriateness of the PTR by comparing it to the RTR for a given indication. Data are used to establish a baseline pattern of antibiotic use in the clinic to gauge the impact of future stewardship activities. Additionally, individual clinics and prescribers are given a snapshot of their antibiotic use compared to other clinics and prescribers. This is a novel means of describing antibiotic use in the outpatient setting that could serve as a standardized model for various adult and pediatric outpatient practices.   Type: Original Research

Consumer interest in community pharmacy HIV screening services

OBJECTIVE

To evaluate consumers' interest in pharmacist-provided human immunodeficiency virus (HIV) screening and to evaluate potential barriers and facilitators to HIV screening in the community pharmacy setting.

METHODS

Cross-sectional survey of adult patients who presented to one of five community (chain and independent) pharmacies from November 2010 to August 2011.

RESULTS

Based on 380 usable surveys, 135 (35.8%) participants were interested in pharmacy-based HIV screening. Independent predictors of interest in HIV screening identified in multivariate analysis (reference groups: ages 30 to 49 years old and white, non-Hispanic race) included younger age (18 to 29 years old) (odds ratio [OR], 2.48; 95% confidence interval [CI], 1.31 to 4.71); black, non-Hispanic race (OR, 2.37; CI, 1.40 to 4.03); and other race (OR, 4.58; CI, 1.63 to 12.87). Lack of perceived risk for HIV was the most commonly cited barrier to HIV screening; and free, rapid, or confidential HIV testing were identified as potential facilitators.

CONCLUSION

Interest in pharmacy-based HIV screening was high among participants representing age and race groups disproportionately affected by HIV. Expansion of HIV screening efforts to community pharmacies warrants further consideration.

Use of CLIA-waived point-of-care tests for infectious diseases in community pharmacies in the United States

Review of point-of-care (POC) testing in community pharmacies, availability and specifications of CLIA-waived infectious disease POC tests, and provide recommendations for future community pharmacy POC models in an effort to improve patient outcomes while reducing antibiotic resistance. PubMed and Medscape were searched for the following keywords: infectious disease, community pharmacy, rapid diagnostic tests, rapid assay, and POC tests. All studies utilizing POC tests in community pharmacies for infectious disease were included. Studies, articles, recommendations, and posters were reviewed and information categorized into general implementation of POC testing in community pharmacies, CLIA-waived tests available, Influenza, Group A Streptococcus pharyngitis, Helicobacter pylori, HIV and Hepatitis C. POC testing provides a unique opportunity for community pharmacists to implement collaborative disease management programmes for infectious diseases and reduce over-prescribing of antibiotics and improve patient outcomes through early detection, treatment and/or referral to a specialist.

Consumer Opinions of Health Information Exchange, e-Prescribing, and Personal Health Records

BACKGROUND

Consumer satisfaction is a crucial component of health information technology (HIT) utilization, as high satisfaction is expected to increase HIT utilization among providers and to allow consumers to become full participants in their own healthcare management.

OBJECTIVE

The primary objective of this pilot study was to identify consumer perspectives on health information technologies including health information exchange (HIE), e-prescribing (e-Rx), and personal health records (PHRs).

METHODS

Eight focus groups were conducted in seven towns and cities across Nebraska in 2013. Each group consisted of 10-12 participants. Discussions were organized topically in the following categories: HIE, e-Rx, and PHR. The qualitative analysis consisted of immersion and crystallization to develop a coding scheme that included both preconceived and emergent themes. Common themes across focus groups were identified and compiled for each discussion category.

RESULTS

The study had 67 participants, of which 18 (27 percent) were male. Focus group findings revealed both perceived barriers and benefits to the adoption of HIT. Common HIT concerns expressed across focus groups included privacy and security of medical information, decreases in quality of care, inconsistent provider participation, and the potential cost of implementation. Positive expectations regarding HIT included better accuracy and completeness of information, and improved communication and coordination between healthcare providers. Improvements in patient care were expected as a result of easy physician access to consolidated information across providers as well as the speed of sharing and availability of information in an emergency. In addition, participants were optimistic about patient empowerment and convenient access to and control of personal health data.

CONCLUSION

Consumer concerns focused on privacy and security of the health information, as well as the cost of implementing the technologies and the possibility of an unintended negative impact on the quality of care. While negative perceptions present barriers for potential patient acceptance, benefits such as speed and convenience, patient oversight of health data, and safety improvements may counterbalance these concerns.

Health Care Resource Utilization and Costs for Influenza-like Illness Among Midwestern Health Plan Members

BACKGROUND

Each year, 6%-20% of U.S. residents are infected by influenza, and more than 200,000 people are hospitalized due to complications related to influenza. In 2003, it was estimated that the direct medical costs for the treatment of influenza were $10.4 billion in the United States. 

OBJECTIVES

To (a) assess the current practice associated with the diagnosis and treatment of influenza-like illnesses (ILIs) in inpatient, ambulatory/outpatient, and emergency room settings and (b) evaluate how the use of rapid influenza diagnostic tests (RIDTs) impacts patient health care utilization and cost in these clinical settings.

METHODS

For this retrospective cohort study, patients with an influenza-related health care encounter were identified using claims data from a midwestern commercial health insurance plan. In order to select the claims relevant to this study, the corresponding influenza ICD-9-CM codes, GPI codes, and CPT codes for the diagnosis, prescriptions, and procedures were identified and used to detect ILI claims. For the cost analysis of these data, the allowed amount in the billing claims was utilized. Using these data, the median cost, mean cost, minimum cost, and maximum cost were determined for each episode of care. The median costs were compared, and Wilcoxon two-sample tests and Kruskal-Wallis tests with a P value of 0.05 were used as the level of significance.

RESULTS

Over 32% of the influenza-like illness episodes identified in this study involved empiric antiviral therapy as either treatment (15%) or prophylaxis (17.1%) without an accompanying medical visit. Of patient episodes with a medical visit, patients with an RIDT for influenza received antiviral treatment in 27.5% of the episodes compared with 55% of the episodes for patients with no RIDT. Episodes with a medical visit and an RIDT had statistically significant (P  less than  0.001) lower median 30-day influenza-related health care costs ($62.46) than episodes with a medical visit but no RIDT ($192.83), as well as with empiric therapy but no accompanying medical visit ($105.64).

CONCLUSIONS

The results of this analysis for ILI claims over a 2-year period suggest that utilization of RIDTs for influenza may reduce overall influenza-related health care costs and improve proper utilization of anti- influenza medications.

Anti-inflammatory effects of rosuvastatin in healthy subjects: a prospective longitudinal study

AIMS

The aims of this study were to determine a mechanism and general timeline for statin related anti-inflammatory activity.

METHODS

Healthy male subjects received rosuvastatin (20 mg daily) for 3 weeks. Blood samples before and after treatment were collected for clinical laboratories and research procedures. Toll-like receptor-4 (tlr-4) expression on blood monocytes was measured using flow cytometry before and after rosuvastatin treatment. Inflammatory molecules were measured before and after rosuvastatin and after blood samples were incubated for 3 hours with or without lipopolysaccharide. Plasma was collected and analyzed for IL-6, TNF-α, IL-8, IGF-1, and sCD14. Comparisons were made using Mann-Whitney rank sum test and paired Student's t-test with significance defined as p≤0.05.

KEY FINDINGS

The expression oftlr-4on blood monocytes was significantly lower after 3 weeks of rosuvastatin (p = 0.046). Consistent with the reduced expression of tlr-4, the TNF-α release from blood receiving LPS trended lower (p = 0.08). None of the other inflammatory markers (IL-8, sCD14, IL-6, IGF-1, C-reactive protein) were modified with rosuvastatin treatment. There were significant declines in total cholesterol (p<0.0001), low-density lipoprotein cholesterol (LDL-C) (p<0.0001), and total cholesterol/high-density lipoprotein cholesterol (HDL-C) ratio (p<0.0001) after 3 weeks of treatment. There was no significant effect on triglycerides, very low-density lipoprotein cholesterol (VLDL-C), or HDL-C.

SIGNIFICANCE

The decline in tlr-4 expression on blood monocytes and TNF-α plasma concentrations after 3 weeks of rosuvastatin treatment suggest a potential mechanism for the anti-inflammatory activity of rosuvastatin.

Health Information Exchange to Support a Prescription Drug Monitoring Program

Objective: To describe barriers to the utilization of a query based Health Information Exchange (HIE) that supports a statewide Prescription Drug Monitoring Program (PDMP). Methods: Emergency room (ER) prescribers were surveyed bi-weekly and at the end of a four-month study to estimate HIE/PDMP utilization and identify barriers to utilization. Results: Self-reported utilization from seventeen providers in three emergency rooms was very low. Providers estimated that prescription history was rarely available when queried. Problem lists and laboratory reports were estimated to be available 60% of the time. Discussion: Barriers to HIE utilization for PDMP purposes included prescribers not finding the information they queried and lack of integration into clinical workflow. Low perceived need for PDMP and prescriber preparedness to manage abusers may also have reduced utilization. Recommendation: Financial and human resources must be available for training and integration of a HIE based PDMP into the ER's clinical workflow. Minimizing information gaps is also necessary to increase utilization.   Type: Case Study

PCMHs, ACOs, and medication management: lessons learned from early research partnerships

The Patient Protection and Affordable Care Act has greatly accelerated the formation of team-based models of care delivery, primarily accountable care organizations (ACOs) and patient-centered medical homes (PCMHs).  Many have written about the need to incorporate medication management services into these systems in order to improve care and reduce total health care costs. Two primary ways of doing so have emerged: (1) an embedded model, whereby pharmacists are employed directly by a physician practice, or (2) a "virtual care team" model, whereby a PCMH or ACO develops an arrangement with external pharmacists in community settings to provide coordinated services.

From physician intent to the pharmacy label: prevalence and description of discrepancies from a cross-sectional evaluation of electronic prescriptions

OBJECTIVE

The objectives of this cross-sectional study were to estimate the prevalence of unintended discrepancies between three sources of prescription information and to describe the types of electronic prescribing system vulnerabilities identified.

METHODS

Staff from community pharmacies identified approximately 200 new prescriptions written at three participating ambulatory care clinics (2 adult, 1 paediatric). Unintended discrepancies were identified by comparing three sources of prescription information: (1) the prescriber's note as documented in the patient's chart; (2) the electronic prescription (e-prescription) entered into the clinic's electronic prescribing software; (3) the medication that was ultimately dispensed by the pharmacy as indicated on the prescription label. The discrepancy rate was calculated by dividing the number of discrepancies identified by the number of prescriptions evaluated.

RESULTS

A total of 602 prescriptions written by 33 prescribers were evaluated from the 3 ambulatory care clinics. The discrepancy rate between the prescriber's note and the e-prescription was 1.7%, 0.6% and 3.9% for the three clinics. The discrepancy rate between the e-prescription (clinic) and the prescription label (pharmacy) was 4.2%, 0.9% and 1.5%. Differences between directions for administration was the most common type of discrepancy identified.

CONCLUSIONS

Discrepancy rates between the prescriber's note and the e-prescription were similar to the discrepancy rates between the e-prescription and pharmacy label. To reduce outpatient medication errors, a better understanding is needed of the sources of discrepancies that occur within the prescriber's clinic, and those that occur between the clinic and pharmacy.

Proton pump inhibitors and acute kidney injury: a nested case-control study

Background

Proton pump inhibitors (PPI) are a widely-used class of drugs for the treatment of gastro-esophageal reflux disease and other acid-related disorders of the gastrointestinal tract. As a class, PPIs have demonstrated a favorable safety profile. However, case reports have suggested that this class of drugs may be linked to acute kidney injury, which may in turn lead to chronic injury or failure. The objective of this study was to determine if an association between PPIs and kidney failure exists and to estimate an effect size for the relationship between PPI use and renal disease.

Methods

A nested case–control study was conducted in a privately insured population in a single Midwestern state including a total of 184,480 patients aged 18 years or older who were continuously enrolled with the insurer for at least 24 months between September 2002 and November 2005.

Of the patients eligible for the study, 854 cases were identified as having at least two claims for an acute renal disease diagnosis. Cases were randomly matched with up to four controls (n = 3,289) based on age, gender, county of residence, and date of entry into the cohort. Patient demographic data, PPI use, illnesses, and medications associated with renal disease and a proxy for health status using pre-existing patient comorbidities were collected from inpatient, professional, and prescription claims data. Conditional logistic regression models were used to evaluate the association between renal disease and PPI use.

Results

Renal disease was positively associated with PPI use (odds ratio [OR] 1.72, 95% confidence interval [CI] 1.27, 2.32, p < 0.001) even after controlling for potential confounding conditions. After removing patients with potential confounding disease states from the study population, the number of cases (195 of the 854) and controls (607) was lower, but the relationship between renal disease and PPI use remained consistent (OR 2.25, CI 1.09-4.62, p < 0.001).

Conclusions

Patients with a renal disease diagnosis were twice as likely to have used a previous prescription for a PPI. Therefore, it is necessary for physicians to increase recognition of patient complaints or clinical manifestations of this potentially harmful event in order to prevent further injury.

Cost-effectiveness of pharmacist-provided treatment of adult pharyngitis

BACKGROUND

There are over 12 million ambulatory care visits for acute pharyngitis annually in the United States. Current guidelines recommend diagnosis through culture or rapid antigen detection test (RADT) and relatively straightforward treatment. Community pharmacists may provide cost-effective care for disease states such as group A streptococcus (GAS) pharyngitis.

OBJECTIVES

The objective of this research is to evaluate the cost-effectiveness of a community pharmacist-as-provider program for the diagnosis and treatment of pharyngitis caused by GAS as compared with standard of care.

METHODS

A cost-effectiveness analysis was conducted to compare treatment for adult pharyngitis patients. In addition to 5 physician-provided treatment strategies, the episodic costs and benefits of treatment provided by pharmacists using RADT and walk-in clinics using RADT were also considered. Model parameters were derived through a comprehensive review of literature and from the Centers for Medicare and Medicaid Services physician fee schedule. Utilities were expressed in quality-adjusted life-days (QALDs) to account for the relatively short duration of most cases of pharyngitis.

RESULTS

Using a cost-effectiveness threshold of $137 per QALD, GAS treatment provided by a pharmacist was the most cost-effective treatment. Pharmacist treatment dominated all of the other methods except physician culture and physician RADT with follow-up culture. The incremental cost-effectiveness ratio (ICER) for physician culture was $6042 per QALD gained and $40,745 for physician RADT with follow-up culture.

CONCLUSIONS

This model suggests that pharmacists may be able to provide a cost-effective alternative for the treatment of pharyngitis caused by GAS in adult patients.

Adherence and dosing frequency of common medications for cardiovascular patients

OBJECTIVES

To compare adherence between once-daily (QD) and twice-daily (BID) dosing with chronic-use prescription medications used by patients with cardiovascular disease.

STUDY DESIGN

Retrospective cohort database analysis.

METHODS

Analysis consisted of 1,077,474 patients aged >18 years with a prescription index date from January 1 to December 31, 2007, for an antidiabetic, antihyperlipidemic, antiplatelet, or cardiac agent with QD or BID dosing. Adherence (medication possession ratio [MPR]) was the number of days of medication supplied between the first prescription fill date and the subsequent 365 days divided by 365 days. Overall mean MPR and comparisons between dosing frequency groups were assessed with a generalized estimating equation. Covariates included age at index date, gender, Charlson comorbidity index, therapeutic class, dosing frequency, and the interaction between therapeutic class and dosing frequency group.

RESULTS

Overall, the adjusted mean MPR ± standard error (SE) value for QD agents was 13.6% greater than BID agents (0.66 ± 0.0006 vs 0.57 ± 0.0016; P <.01). The adjusted mean MPR value for QD agents was 2.9%, 17.5%, and 29.4% greater than BID agents in the antidiabetic, antihyperlipidemic, and antiplatelet therapeutic classes, respectively. For cardiac agents, the adjusted mean MPR value was similar between QD and BID agents. Carvedilol represented approximately 80% of the cardiac agents in the BID group. The adjusted mean MPR ± SE for carvedilol phosphate QD was 0.73 ± 0.0024 and 0.65 ± 0.0027 for carvedilol BID (11% difference; P <.01).

CONCLUSIONS

In this large analysis, the QD dosing regimen was related to greater adherence versus a BID regimen.

Trends in community pharmacy counts and closures before and after the implementation of Medicare part D

PURPOSE

Medicare Part D provided 3.4 million American seniors with prescription drug insurance. It may also have had an unintended effect on pharmacy viability. This study compares trends in the number of pharmacies and rate of pharmacy closures before and after the implementation of Medicare Part D.

METHODS

This retrospective observational study used data from National Council for Prescription Drug Programs (NCPDP) to track retail pharmacy closures and counts between January 2004 and January 2009. Pharmacies were classified by ownership (chain or independent), location (urban or rural), and whether they were the only pharmacy in a community. Autoregressive Integrated Moving Average (ARIMA) models were used to examine trends in pharmacy counts and closures.

FINDINGS

The number of independent and rural pharmacies decreased significantly after the implementation of Medicare Part D. The number of communities that saw their only pharmacy close also increased.

CONCLUSIONS

Unintended consequences of Medicare Part D may serve to reduce patient access to pharmacy services in opposition to the stated goals of the program.

Student-run low-income family medicine clinic: controlling costs while providing comprehensive medication management

OBJECTIVES

To evaluate the impact of implementing cost-control measures on drug use and financial performance of a student-run safety net clinic and to assess the effect of the measures on patient care.

METHODS

Medication histories and patient information were obtained from the University of Nebraska Medical Center's student-run safety net clinics' (SHARING and GOODLIFE) computer databases and internal medication cost documents for all patients treated with medications at the clinics from April 1, 2006, through March 31, 2008. Main outcome measures were cost, use, and source of all medications and the resultant financial savings between the pre- and post-periods.

RESULTS

200 patients were treated with medications during the 2-year period (164 patients before April 1, 2007, and 137 after). A majority of clinic patients were treated for chronic conditions, including 62% for hypertension, 54% for diabetes, 46% for dyslipidemia, and 26% for depression. The average monthly cost to the clinics for medications decreased from $5,444.87 before April 1, 2007, to $3,714.05 (P = 0.002) after. With these changes, the cost per prescription from any delivery method decreased from $15.28 to $13.02 (P < 0.001) and the average cost per prescription decreased from $27.32 to $20.27 (P < 0.001) after formulary implementation. The number of prescriptions per patient per month was unchanged.

CONCLUSION

Medication management with a closed formulary in a diverse uninsured population reduced expenditures, with the largest savings coming from using prescriptions more efficiently while also providing a similar level of medical care.

Reduction in mortality associated with statin therapy in patients with severe sepsis

STUDY OBJECTIVE

To evaluate the effect of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) on mortality in patients with severe sepsis.

DESIGN

Retrospective cohort study.

SETTING

Intensive care unit (ICU) of an academic medical center.

PATIENTS

One hundred eighty-eight patients aged 40 years or older with a diagnosis of severe sepsis and an ICU stay between January 1, 2005, and December 31, 2006.

MEASUREMENTS AND MAIN RESULTS

Patient demographic data, statin use, and Acute Physiology and Chronic Health Evaluation (APACHE) II scores at the time of sepsis diagnosis were collected from the patient database. We used a multivariable logistic regression model to evaluate the association between statin use and in-hospital all-cause mortality after controlling for age, sex, and severity of illness. Of the 188 patients who met our inclusion criteria, 60 (32%) had statin exposure. Patients receiving statins were similar in age, sex, and APACHE II scores to those not receiving statins. In the univariable comparison, the statin group had a 35% relative reduction in mortality compared with the nonstatin group (mortality rate 31.7% vs 48.4%, p=0.040). Most of the mortality reduction attributed to statins occurred in patients with APACHE II scores higher than 24 (mortality rate 32.3% vs 57.5%, p=0.031), with a minimal mortality difference in patients with APACHE II scores of 24 or lower (31% vs 36.4%, p=0.810). In the multivariable regression model, statin use had a protective effect (odds ratio [OR] 0.42, 95% confidence interval [CI] 0.21-0.84, p=0.014), whereas increasing age (OR 1.03, 95% CI 1.01-1.06, p=0.013) and higher APACHE II score (OR 1.11, 95% CI 1.05-1.18, p=0.001) were associated with increased mortality.

CONCLUSION

The use of statins was associated with a protective effect in patients with severe sepsis, as demonstrated by a significant reduction in mortality compared with patients not receiving statins.
