Interdisciplinary Deprescribing of Aspirin Through Prescriber Education and Provision of Patient-Specific Recommendations.

BACKGROUND: Inappropriate aspirin use can lead to increased frequency of bleeding events and poor patient outcomes. OBJECTIVES: Compare current aspirin prescribing to guideline recommendations and analyze the impact of pharmacist education for clinicians with provision of patient-specific recommendations. METHODS: Internal medicine residents received 1 educational session on appropriate aspirin use. Over a 5-month period post-education, 100 patients on aspirin with a clinic appointment were screened and their charts reviewed. Aspirin use was classified based on guideline recommendations as follows: (1) recommended, (2) weigh the risk and benefits, (3) not recommended, (4) dose change recommended, or (5) outside of guideline recommendation. A recommendation for aspirin deprescribing was then communicated to the clinician prior to the patient's appointment. Prescriber practice following the appointment was collected and analyzed. RESULTS: Inappropriate aspirin use occurred in 29% (n = 29) of patients prior to their appointment. Of these, aspirin was not recommended in 65.5% (n = 19), and a dose reduction from 325 mg to 81 mg was recommended in 34.5% (n = 10). Of the 81 patients who kept their appointment, pharmacist recommendations to deprescribe aspirin were communicated to the clincian for 20 patients (24.7%) and resulted in a 55% aspirin deprescription. CONCLUSIONS: The majority of patients identified as using aspirin inappropriately fell into 3 groups: (1) patients taking 325 mg aspirin, (2) patients taking aspirin for primary prevention, and (3) patients taking aspirin concomitantly with an anticoagulant. Strategies that may lead to optimization of aspirin use include lectures and patient-specific chart reviews with pharmacist recommendation.

Preliminary outcomes of preemptive warfarin pharmacogenetic testing at a large rural healthcare center.

PURPOSE: As a preliminary evaluation of the outcomes of implementing pharmacogenetic testing within a large rural healthcare system, patients who received pre-emptive pharmacogenetic testing and warfarin dosing were monitored until June 2017. SUMMARY: Over a 20-month period, 749 patients were genotyped for VKORC1 and CYP2C9 as part of the electronic Medical Records and Genomics Pharmacogenetics (eMERGE PGx) study. Of these, 27 were prescribed warfarin and received an alert for pharmacogenetic testing pertinent to warfarin; 20 patients achieved their target international normalized ratio (INR) of 2.0-3.0, and 65% of these patients achieved target dosing within the recommended pharmacogenetic alert dose (± 0.5 mg/day). Of these, 10 patients had never been on warfarin prior to the alert and were further evaluated with regard to time to first stable target INR, bleeds and thromboembolic events, hospitalizations, and mortality. There was a general trend of faster time to first stable target INR when the patient was initiated at a warfarin dose within the alert recommendation versus a dose outside of the alert recommendation with a mean (± SD) of 34 (± 28) days versus 129 (± 117) days, respectively. No trends regarding bleeds, thromboembolic events, hospitalization, or mortality were identified with respect to the pharmacogenetic alert. The pharmacogenetic alert provided pharmacogenetic dosing information to prescribing clinicians and appeared to deploy appropriately with the correct recommendation based upon patient genotype. CONCLUSION: Implementing pharmacogenetic testing as a standard of care service in anticoagulation monitoring programs may improve dosage regimens for patients on anticoagulation therapy.

Comparison of Prescribing Practices with Direct Acting Oral Anticoagulant Protocols.

BACKGROUND: The goal of anticoagulation management programs is to prevent thrombosis while minimizing the risks of hemorrhage. Direct acting oral anticoagulants (DOACs) selectively inhibit coagulation proteins to inhibit thrombosis. Previous studies suggest patient monitoring and education provided through anticoagulation services enhance adherence and decrease adverse outcomes in patients receiving DOAC therapy. OBJECTIVE: The objectives of this study were to describe DOAC prescribing adherence to anticoagulation service protocols and to observe whether enrollment in an anticoagulation service resulted in greater prescribing adherence to DOAC protocols. METHODS: A retrospective cohort study evaluated all initial prescriptions of apixaban, dabigatran, and rivaroxaban at Marshfield Clinic from 19 October 2010 to 21 August 2014. Three algorithms analyzed patient and prescription data extracted from the organization's electronic health record and classified prescriptions as per protocol or not per protocol. The algorithms classified not per protocol prescriptions as off-label indication, renal impairment [estimated glomerular filtration rate (eGFR) <30 ml/min], hepatic impairment (rivaroxaban and apixaban), advanced age >74 years (dabigatran), dose too low, or dose too high. The analysis assessed whether enrollment in the Marshfield Clinic Anticoagulation Service DOAC monitoring process was associated with increased adherence to protocols. RESULTS: In aggregate, 72% of apixaban prescriptions, 52% of dabigatran prescriptions, and 70% of rivaroxaban prescriptions were per protocol. Off-label indications and dosage too low were the most common not per protocol reasons for apixaban and rivaroxaban prescriptions. Age ≥75 years and off-label indication were the most common not per protocol reasons for dabigatran prescriptions. Enrollment in the anticoagulation service process was not associated with increased adherence to protocols. CONCLUSION: A significant proportion of DOAC prescriptions did not adhere to protocol expectations. While enrollment in DOAC management through the Marshfield Clinic Anticoagulation Service was not associated with increased adherence to protocols, opportunities exist to optimize DOAC prescribing. Defining ideal DOAC management requires additional research.

Best practices: an electronic drug alert program to improve safety in an accountable care environment.

BACKGROUND: The accountable care organization (ACO), one of the most promising and talked about new models of care, focuses on improving communication and care transitions by tying potential shared savings to specific clinical and financial benchmarks. An important factor in meeting these benchmarks is an ACO's ability to manage medications in an environment where medical and pharmacy care has been integrated. The program described in this article highlights the critical components of Marshfield Clinic's Drug Safety Alert Program (DSAP), which focuses on prioritizing and communicating safety issues related to medications with the goal of reducing potential adverse drug events. PROGRAM DESCRIPTION: Once the medication safety concern is identified, it is reviewed to evaluate whether an alert warrants sending prescribers a communication that identifies individual patients or a general communication to all physicians describing the safety concern. Instead of basing its decisions regarding clinician notification about drug alerts on subjective criteria, the Marshfield Clinic's DSAP uses an internally developed scoring system. The scoring system includes criteria developed from previous drug alerts, such as level of evidence, size of population affected, severity of adverse event identified or targeted, litigation risk, available alternatives, and potential for duration of medication use. Each of the 6 criteria is assigned a weight and is scored based upon the content and severity of the alert received.  OBSERVATIONS: In its first 12 months, the program targeted 6 medication safety concerns involving the following medications: topiramate, glyburide, simvastatin, citalopram, pioglitazone, and lovastatin. Baseline and follow-up prescribing data were gathered on the targeted medications. Follow-up review of prescribing data demonstrated that the DSAP provided quality up-to-date safety information that led to changes in drug therapy and to decreases in potential adverse drug events. In aggregate, nearly 10,000 total potential adverse drug events were identified with baseline data from the DSAP initiatives, and nearly 8,000 were resolved by changes in prescribing.  IMPLICATIONS: Implications and additional thoughts from The Working Group on Optimizing Medication Therapy in Value-Based Healthcare were provided for the following categories: leveraging electronic health records, importance of data collection and reassessment, preventing alert fatigue utilizing various techniques, relevance to ACO quality measurement, and limitations of a retrospective system. RECOMMENDATIONS: While health information technologies have been recognized as a cornerstone for an ACO's success, additional research is needed on comparing these types of technological innovations. Future research should focus on reviewing comparable scoring criteria and alert systems utilized in a variety of ACOs. In addition, an examination of different data mining procedures used within different electronic health record platforms would prove useful to ACOs looking to improve the care of not only the subpopulations with specific metrics associated with them, but their patient population as a whole. The authors also highlight the need for additional research on health information exchanges, including the cost and resource requirements needed to successfully participate in these types of networks.

Clinical pharmacy should adopt a consistent process of direct patient care.

Although the application of a consistent process of care serves as a foundational principle for most health care professions, this is not true for the discipline of clinical pharmacy. Without an explicit, reproducible process of care, it is not possible to demonstrate to patients, caregivers, or health professionals the ways in which the clinical pharmacist can reliably contribute to improved medication-related outcomes. A consistent patient care process should describe the key steps that all clinical pharmacists will follow when they encounter a patient, regardless of the type of practice, the clinical setting, or the medical conditions or medications involved. Four essential elements serve as the cornerstones of the clinical pharmacist's patient care process: assess the patient and his or her medication therapy, develop a plan of care, implement the plan, and evaluate the outcomes of the plan. Despite the fact that several processes of care have been advocated for clinical pharmacists, none has been adopted by the clinical pharmacy discipline. In addition, numerous publications evaluate outcomes related to clinical pharmacy services, but it is difficult to determine what process of patient care was used in most of these studies. In our view, a consistent process of direct patient care that includes the four essential elements should be adopted by the clinical pharmacy discipline. This process should be clear, straightforward and intuitive, readily documentable, and applicable to all practice settings. Once adopted, the process should be implemented across practice settings, taught in professional degree programs, integrated into students' clinical rotations, refined during residency training, and used as a foundation for future large-scale studies to rigorously study the effects of the clinical pharmacist on patients' medication-related outcomes.

Assessment of dabigatran utilization and prescribing patterns for atrial fibrillation in a physician group practice setting.

For years, warfarin and aspirin have been standard therapies for prophylaxis of stroke in atrial fibrillation. In late 2010, dabigatran, an oral direct thrombin inhibitor, became available for use in nonvalvular atrial fibrillation. We sought to evaluate utilization and prescribing patterns of dabigatran in a physician group practice setting. We retrospectively collected prescription data from October 2010 to December 2011 including indication of use, dose, renal function, drug interactions, history of warfarin therapy, and risk assessment scores (CHADS2 and HAS-BLED). Off-label use (history of valve disease or no diagnosis of atrial fibrillation) occurred in 20% (n = 34) of 174 patients. Renal function assessed by Cockcroft-Gault equation identified 1 case of contraindicated use and the need for initial renal dose adjustment in approximately 1/2 of the patients with reduced renal function (15-30 ml/min). Review of anticoagulant use revealed 68% of patients (n = 119) previously received warfarin and ultimately 20% of all patients on dabigatran resumed warfarin therapy. A significant increase in the use of permeability glycoprotein inhibitors and proton pump inhibitors after initiating dabigatran was observed. Nearly 10% of patients had a CHADS2 score of 0. For patients receiving novel oral anticoagulants, prospective inclusion in anticoagulation services and guidance from specific "place in therapy" statements have potential to play a large role in maximizing safety while aiding in continued research.

Designing a pharmacy residency program: focus on a common accreditation challenge.

PURPOSE: One organization's stepwise approach to achieving full compliance in an area often cited for improvement in pharmacy residency accreditation surveys is described. SUMMARY: Principle 4 of the American Society of Health-System Pharmacists (ASHP) accreditation standard for postgraduate year 1 (PGY1) residencies lists requisite components of program design, conduct, and evaluation; many organizations seeking accreditation are evaluated as being in partial compliance with one or more elements of Principle 4. Several years ago, the Marshfield Clinic, a physician group practice in Wisconsin, launched an initiative to expand its postgraduate medical training program to include a PGY1 pharmacy residency. After a gap analysis of current practices and accreditation requirements, monthly meetings of pharmacy, faculty, and corporate leaders were conducted to address program development challenges, with ongoing input from the clinic's division of education. Strategies were developed for meeting all Principle 4 criteria. For example, with regard to component 4.2 (Program Delivery), the clinic developed a residency program handbook including standing operating procedures and a residency preceptor guide with a trainee evaluation scale, professional development resources, and guidance on providing resident feedback. After an internally conducted mock site visit to identify and resolve Principle 4 issues and other compliance issues, the clinic underwent an ASHP site visit and was subsequently accredited by the ASHP Commission on Credentialing. CONCLUSION: Marshfield Clinic used an efficient step-by-step process in the development of its PGY1 pharmacy residency program and achieved full compliance with all of the criteria outlined in Principle 4 of the ASHP accreditation standard.

Patient and phaRmacist telephonic encounters (PARTE) in an underserved rural patient population with asthma: results of a pilot study.

OBJECTIVE: To assess the feasibility, acceptability, and preliminary impact of a telepharmacy intervention in an underserved, rural asthma patient population. SUBJECTS AND METHODS: Patients with asthma were randomized to receive either standard care or telephone consultations from pharmacists regarding asthma self-management over a 3-month period. Qualitative interviews were conducted to identify participants' attitudes/opinions regarding the intervention. Baseline and follow-up surveys assessed asthma control, patient activation, and medication utilization. RESULTS: Ninety-eight adults were recruited (78% accrual); 83 completed the study (15% dropout). Participants reported positive opinions and believed the intervention improved their asthma self-management. The intervention group had significantly higher patient activation compared with the control (p<0.05). There were no significant between-group differences regarding asthma control. However, within-group analyses of the intervention group showed an improvement in asthma control (p<0.01) and medication adherence (p<0.01). No within-group differences were found for the control group. CONCLUSIONS: This telepharmacy intervention is feasible and showed indicators of effectiveness, suggesting the design is well suited for a robust study to evaluate its impact in uncontrolled asthma patients. Pharmacists helping patients manage asthma through telecommunications may resolve access barriers and improve care.

Telephonic monitoring and optimization of inhaler technique.

INTRODUCTION: Improper inhaler technique is a common problem affecting asthma control and healthcare costs. Telephonic asthma management can increase access to care while reducing costs and hospitalizations. However, no reliable method has been established for telephonically evaluating and correcting inhaler technique. OBJECTIVE: The purpose of this study was to pilot test a method for assessing and correcting patient inhaler technique via telephone. METHODS: Participants (n=30) were adults with asthma using metered-dose inhalers (MDIs) and diskus inhalers. A pharmacist was located in one room and communicated via telephone with a participant in another room. The pharmacist telephonically assessed and taught inhaler technique. Participants were video-recorded, and videos were later examined by a second pharmacist to visually evaluate inhaler technique. Participants were assigned pre- and posteducation inhaler technique scores for the telephonic and video assessments. Scores were based on summated scales for MDI (0-9) and diskus (0-11) inhalers. Paired samples t-tests were used to compare telephone and video assessments. RESULTS: Findings indicated a significant difference between the telephone and video assessments of MDI technique (p<0.05); however, no difference was found for the diskus inhaler. Comparing pre- and posteducation inhaler technique for MDI and diskus, mean scores significantly improved from 5.7 to 7.8 (p<0.05) and from 8.5 to 10.4 (p<0.05), respectively. CONCLUSIONS: The telephonic method was able to improve and detect some deficiencies in patients' inhaler technique. However, modifications and further investigation will more clearly determine the role and value of such a telephonic intervention.

Patient And phaRmacist Telephonic Encounters (PARTE) in an underserved rural population with asthma: methods and rationale.

PURPOSE: Methods used to deliver and test a pharmacy-based asthma care telephonic service for an underserved, rural patient population are described. SUMMARY: In a randomized controlled trial (RCT), the Patient And phaRmacist Telephonic Encounters (PARTE) project is assessing the feasibility, acceptability, and preliminary impact of providing pharmacy-based asthma care service telephonically. The target audience is a low income patient population across a large geographic area served by a federally qualified community health center. Ninety-eight participants have been randomized to either standard care or the intervention group who received consultation and direct feedback from pharmacists via telephone regarding their asthma self-management and medication use. Pharmacists used a counseling framework that incorporates the Indian Health Services 3 Prime Questions and the RIM Technique (Recognition, Identification, and Management) for managing medication use problems. Pharmacists encouraged patients to be active partners in the decision-making process to identify and address the underlying cause of medication use problems. Uniquely, this trial collected process and summative data using qualitative and quantitative approaches. Pharmacists' training, the fidelity and quality of pharmacists' service delivery, and short term patient outcomes are being evaluated. This evaluation will improve our ability to address research challenges and intervention barriers, refine staff training, explore patient perspectives, and evaluate measures' power to provide preliminary patient outcome findings. CONCLUSION: A mixed method evaluation of a structured pharmacist intervention has the potential to offer insights regarding staff training, service fidelity and short term outcomes using quantitative and qualitative data in an RCT. Results will provide evidence regarding the feasibility and quality of carrying out the study and service delivery from the multiple perspectives of participants, clinicians, and researchers.
