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 Researc

An Evaluation of Managing and Educating Patients on the Risk of Glucocorticoid-Induced Osteoporosis

AbstractObjectiveTo assess the impact of risk management activities on patient risk of glucocorticoid-induced osteoporosis.MethodsNinety-six adult patients taking chronic glucocorticoid therapy in 15 community pharmacies. Patients in the control group received usual and customary care. Patients in the treatment pharmacies received education and an educational pamphlet about the risks of glucocorticoid-induced osteoporosis. In addition, the treatment group pharmacists monitored the patients' drug therapy, to identify and address drug-related problems. Data including the glucocorticoid taken by the patient, medications, and osteoporosis risk factors were collected at baseline and after 9 months of monitoring, via Web-based survey completed in the pharmacy. Using an intent to treat approach, the pre–post frequency changes were compared with contrasts for presence of bisphosphonate therapy, presence of estrogen therapy, presence of calcium supplement, discussion of glucocorticoid-induced osteoporosis risk, discussion of bone density test, presence of bone mineral density test, reported inactivity, and reported low calcium diet.ResultsThe contrast was significant in favor of the treatment pharmacies for the frequency of patients taking a calcium supplement (Control [−6.9%] vs. Treatment [17.1%], P < 0.05). No other contrast was significant.ConclusionsCommunity pharmacists are capable of increasing calcium supplementation among patients at risk for glucocorticoid-induced osteoporosis. Pharmacists who educate at-risk patients can impact the self-care of these patients

A feasibility service evaluation of screening and treatment of group A streptococcal pharyngitis in community pharmacies

Objectives The UK 5 year antimicrobial resistance strategy recognizes the role of point-of-care diagnostics to identify where antimicrobials are required, as well as to assess the appropriateness of the diagnosis and treatment. A sore throat test-and-treat service was introduced in 35 community pharmacies across two localities in England during 2014–15. Methods Trained pharmacy staff assessed patients presenting with a sore throat using the Centor scoring system and patients meeting three or all four of the criteria were offered a throat swab test for Streptococcus pyogenes, Lancefield group A streptococci. Patients with a positive throat swab test were offered antibiotic treatment. Results Following screening by pharmacy staff, 149/367 (40.6%) patients were eligible for throat swab testing. Of these, only 36/149 (24.2%) were positive for group A streptococci. Antibiotics were supplied to 9.8% (n = 36/367) of all patients accessing the service. Just under half of patients that were not showing signs of a bacterial infection (60/123, 48.8%) would have gone to their general practitioner if the service had not been available. Conclusions This study has shown that it is feasible to deliver a community-pharmacy-based screening and treatment service using point-of-care testing. This type of service has the potential to support the antimicrobial resistance agenda by reducing unnecessary antibiotic use and inappropriate antibiotic consumption

Acceptability and Feasibility of a Pharmacist-Led HIV Pre-Exposure Prophylaxis (PrEP) Program in the Midwestern United States

BACKGROUND: 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 two community-based clinics. Through a collaborative practice agreement, pharmacists conducted PrEP visits with potential candidates for PrEP, according to the recommended CDC 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

Phase-resolved Crab pulsar measurements from 25 to 400 GeV with the MAGIC telescopes

We report on observations of the Crab pulsar with the MAGIC telescopes. Our data were taken in both monoscopic (> 25GeV) and stereoscopic (> 50GeV) observation modes. Two peaks were detected with both modes and phase-resolved energy spectra were calculated. By comparing with Fermi- LAT measurements, we find that the energy spectrum of the Crab pulsar does not follow a power law with an exponential cutoff, but has an additional hard component, extending up to at least 400 GeV. This suggests that the emission above 25 GeV is not dominated by curvature radiation, as suggested in the standard scenarios of the OG and SG models.Comment: 4 pages, 2 figures, Proc.

Midwest Pharmacists\u27 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\u27 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\u27 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

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. &nbsp; Type:&nbsp;Case Stud

A major electronics upgrade for the H.E.S.S. Cherenkov telescopes 1-4

The High Energy Stereoscopic System (H.E.S.S.) is an array of imaging atmospheric Cherenkov telescopes (IACTs) located in the Khomas Highland in Namibia. It consists of four 12-m telescopes (CT1-4), which started operations in 2003, and a 28-m diameter one (CT5), which was brought online in 2012. It is the only IACT system featuring telescopes of different sizes, which provides sensitivity for gamma rays across a very wide energy range, from ~30 GeV up to ~100 TeV. Since the camera electronics of CT1-4 are much older than the one of CT5, an upgrade is being carried out; first deployment was in 2015, full operation is planned for 2016. The goals of this upgrade are threefold: reducing the dead time of the cameras, improving the overall performance of the array and reducing the system failure rate related to aging. Upon completion, the upgrade will assure the continuous operation of H.E.S.S. at its full sensitivity until and possibly beyond the advent of CTA. In the design of the new components, several CTA concepts and technologies were used and are thus being evaluated in the field: The upgraded read-out electronics is based on the NECTAR readout chips; the new camera front- and back-end control subsystems are based on an FPGA and an embedded ARM computer; the communication between subsystems is based on standard Ethernet technologies. These hardware solutions offer good performance, robustness and flexibility. The design of the new cameras is reported here.Comment: Proceedings of the 34th International Cosmic Ray Conference, 30 July- 6 August, 2015, The Hague, The Netherland
