Benefit of clinical pharmacists in neurology clinics at an academic medical center.

BACKGROUND: Patients with neurologic diseases have complex medical needs and may benefit from the addition of clinical pharmacists in their care. OBJECTIVES: This study aimed to describe integration and benefit of clinical pharmacists in neuroimmunology and neuromuscular clinics at an academic medical center. METHODS: This retrospective chart review evaluated patients initiated on a neurology medication for a neuroimmunology or neuromuscular disease state before and after pharmacist integration in neurology clinics. The primary outcome measured access to an initially prescribed neuroimmunology or neuromuscular medication within 90 days of prescription. Secondary outcomes included access to an initially prescribed or alternative neurology medication owing to insurance requirements within 90 days, time from initial prescription to start, and description of pharmacist involvement. RESULTS: There were 101 patients in the pregroup and 101 patients in the postgroup. The percentage of patients with confirmed initially prescribed medication access at 90 days increased in the postgroup compared with the pregroup (87.1% vs. 72.5%, respectively, P = 0.014). For secondary outcomes, the percentage of patients who started on an initially prescribed or alternative neuroimmunology or neuromuscular medication within 90 days also increased in the postgroup compared with the pregroup (90.0% vs. 73.3%, respectively, P = 0.004). Additional pharmacist involvement occurred in 64 patients (63.4%) in the postgroup and included prior authorization approval assistance, drug information support, and medication liaison interventions, with an average of 4.7 pharmacist interventions at each pharmacy-led encounter. CONCLUSION: The addition of pharmacists into neuroimmunology and neuromuscular clinics improved operational access to medications for neuroimmunology and neuromuscular conditions. In addition, pharmacists were able to assist with multiple areas of patient care including medication education, monitoring, and serving as a medication liaison. This study supports continuing to offer clinical pharmacy services in neuroimmunology and neuromuscular departments and may support the addition of clinical pharmacists into neurology services at other institutions.

The Impact of a Diabetes Transitions of Care Clinic on Hospital Utilization and Patient Care.

BACKGROUND: There is currently limited guidance from the American Diabetes Association regarding transitions of care for patients with diabetes. OBJECTIVE: This study's aim was to determine the impact of a diabetes-specific transitions of care clinic (TOCC) on hospital utilization and patient outcomes in recently discharged patients with diabetes. METHODS: This retrospective study evaluated patients seen by TOCC as compared with similar patients discharged from the study institution the year prior. The primary outcome was a composite of the number of unique patients with readmissions/emergency department (ED) visits within 30 days of discharge. Secondary outcomes included a subcomponent analysis of readmissions/ED visits, index hospital length of stay (LOS), and to describe clinical interventions made in clinic. This study was approved by the institutional review board of the Office of Responsible Research Practice at the Ohio State University Wexner Medical Center. RESULTS: There were 165 patients in the TOCC group and 157 in the control group based on the matching criteria. There was a statistically significant decrease in the primary outcome in the TOCC group versus the control group (18% vs 36%, P < 0.001). In evaluation of its subcomponents, there was a statically significant decrease in patients with readmissions (11% vs 26%, P < 0.001) but not ED visits (10% vs 17%, P = 0.096). The LOS for the TOCC group was shorter at 4 days versus 5 days in the control group (P = 0.055). CONCLUSIONS AND RELEVANCE: The implementation of a diabetes-specific TOCC can decrease both readmissions and ED visits and may impact hospital LOS. In addition, a TOCC can be used to identify gaps in preventive care. The results from this study may help support the creation of similar TOCC at other institutions.

Trends in anticoagulation management services following incorporation of direct oral anticoagulants at a large academic medical center.

The introduction of direct oral anticoagulants (DOACs) to the market has expanded anticoagulation options for outpatient use. Routine evaluation by health care professionals is recommended as it is with warfarin, therefore requiring adjustments in practices of anticoagulation management services (AMS). This study aims to describe trends that occurred following the incorporation of DOACs into AMS at a large academic medical center. A retrospective chart review of pharmacist-run AMS was used to compare patients on DOAC therapy versus other types of anticoagulation, including warfarin and parenteral agents. Primary outcomes included trends in the number of unique patients, management encounters, and telephone encounters throughout the study period. Secondary outcomes included trends in new encounters, and changes in patient characteristics, resources utilized, and patient satisfaction scores. A total of 2976 unique patients, 74,582 management encounters, and 13,282 telephone encounters were identified. From study beginning to end, results showed stable numbers of unique patients, an increase in management encounters for the DOAC group and decrease in the other anticoagulants group, and stable numbers of telephone encounters. Additionally, the number of new encounters for both groups increased. Throughout the study, pharmacy resources were reallocated within anticoagulation to adapt to the changing trends and patient satisfaction reached targets. Patients' characteristics remained stable, with the DOAC group having fewer comorbid conditions and concomitant medications that could increase bleed risk. This study showed that by reallocating resources within anticoagulation, AMS can maintain stable patient populations while continuing to expand access and satisfy patients following DOAC inclusion.

Improvement in the medication reconciliation postdischarge quality measure after implementation of a pharmacist-run service.

OBJECTIVE: This study aimed to evaluate the impact of a pharmacist-led postsurgical discharge medication reconciliation program in an accountable care organization-like setting. SETTING: Multidisciplinary primary care network in Central Ohio. PRACTICE DESCRIPTION: Ambulatory care pharmacists are integrated in a primary care network, which includes a centralized focus on assistance with population health metrics, along with an interdisciplinary team. PRACTICE INNOVATION: In May 2018, a pharmacist-led medication reconciliation postdischarge (MRP) program was initiated focused on a postsurgical discharge population. EVALUATION: A retrospective chart review was conducted to compare the 2 primary end points of overall MRP rates from 4 payers in 2017 and 2018, and the postsurgical MRP rates from May 25 to November 30 of 2017 and 2018. Secondary outcomes included description of pharmacist interventions in pharmacy-led service and 30-day readmission or emergency department (ED) utilization rates for postsurgical population. RESULTS: A total of 5837 hospitalizations were identified as eligible for overall MRP completion in 2017 (n = 2621) and 2018 (n = 3216). A 20% relative increase in overall MRP completion was reported in 2018 (P < 0.001). In 2017, 55.9% of postsurgical MRPs were completed. The implementation of the pharmacy-led MRP program led to a 41% relative increase in postsurgical MRP completion (78.9% in 2018, P < 0.001). Pharmacists completed 220 postsurgical MRPs in the 6-month study period, including 765 total recommendations for intervention and an average of 3 recommendations and 4 medication list updates per MRP. There was no statistically significant reduction in 30-day readmission and ED utilization rates in 2018 (6.8% in 2017 vs. 6.2% in 2018, P = 0.74). CONCLUSION: A pharmacy-led postsurgical discharge program led to an increase in MRP completion rates in the target postsurgical MRP population, which also positively affected the overall MRP completion rate. Pharmacists can be key players in the improvement and quality of MRP measures.

Initiation and outcomes with Class Ic antiarrhythmic drug therapy.

BACKGROUND: Expert opinion recommends performing exercise testing with initiation of Class Ic antiarrhythmic medication. OBJECTIVE: To evaluate the rate and reason for discontinuation of Ic agent within the first year of follow up, with particular attention to rate of proarrhythmia and the value of routine treadmill testing. METHODS: This is a single center retrospective cohort study including consecutive patients with atrial arrhythmias who were initiated on a Class Ic agent from 2011 to 2016. Data was collated from chart review and pharmacy database. RESULTS: The study population included 300 patients (55% male, mean age 61; mean ejection fraction, 56%) started on flecainide (n = 153; 51%) and propafenone (n = 147; 49%). Drug initiation was completed while hospitalized on telemetry and the staff electrophysiologists directed dosing. There was one proarrhythmic event during initiation (0.3%). The primary reason for not being discharged on Ic agent was due to detection of proarrhythmia (n = 15) or ischemia (n = 1) with treadmill testing (5.3%). Exercise testing was the single significant variable to affect the decision to discontinue Ic drug, p < 0.0001 (95% CI: 1.89-6.08%). During follow up, the primary reason for discontinuation of Ic agent was lack of efficacy, 32%. CONCLUSIONS: With proper screening, initiation of Class Ic agent is associated with very low rate of proarrhythmia. Treadmill testing is of incremental value and should be completed in all patients after loading Class Ic antiarrhythmic.

Evaluation of a pharmacist-managed electrolyte protocol in outpatients on antiarrhythmic medications.

OBJECTIVE: To evaluate the effectiveness of a pharmacist-managed treatment protocol in achieving and maintaining serum potassium level ([K+]) in the desired range. SETTING: Antiarrhythmic Medications Clinic, The Ohio State University Wexner Medical Center, Columbus, Ohio, from 2009 to 2013. PRACTICE DESCRIPTION: Patients are referred for antiarrhythmic monitoring at this pharmacist-run, electrophysiologist-supervised clinic. Each visit includes medication reconciliation for drug interaction identification, patient interview for potential adverse effects or arrhythmia symptoms, patient education, and drug therapy monitoring through ordering and review of objective testing. PRACTICE INNOVATION: In 2009, a novel, pharmacist-managed electrolyte protocol was established for less than ideal [K+] found during antiarrhythmic monitoring. The protocol was intended to standardize and improve practice, versus pre-protocol management through separate electrophysiology offices. The protocol was designed to maintain [K+] of 4.0-5.0 mmol/L, and it used dietary advice and magnesium and potassium supplementation to normalize [K+]. EVALUATION: The performance of the pharmacist-managed electrolyte protocol was evaluated in consecutive patients seen between June 2009 and July 2013 with [K+] less than 4.0 mmol/L. [K+] during initial visit and laboratory tests were scheduled at weekly intervals after intervention until corrected. Maintenance of [K+] was assessed during the next visit to the clinic. Patients whose management involved pre-protocol between October 2008 and May 2009 at the clinic served as controls. RESULTS: One-hundred ninety-one encounters were evaluated from the post-protocol (treatment) group and 41 encounters from the pre-protocol (control) group. Desired [K+] was reached in 161 (84%) post-protocol patient encounters, compared with 21 (49%) in the control group (P < 0.01). Median time to target was 14 days (range, 3-203 days) in the treatment group and 146 days (range, 7-285 days) in the control group (P < 0.01). Of 125 encounters that received follow-up in the treatment group, 75% remained at desired [K+]. CONCLUSION: A pharmacist-managed electrolyte protocol, implemented as part of a comprehensive antiarrhythmic monitoring service, effectively achieves and maintains desired [K+].

Impact of Clinical Pharmacists in the Inflammatory Bowel Disease Clinic.

Background: Limited evidence exists regarding pharmacist involvement and impact in inflammatory bowel disease (IBD) interdisciplinary clinic care models. The purpose is to describe pharmacist utilization in an interdisciplinary IBD clinic and evaluate clinical impact on patient quality of life. Methods: This was a retrospective cohort study comparing outcomes in patients with Crohn's disease initiated on therapy when the implementation of pharmacy services began (Early Phase) to the expansion of pharmacy services (Recent Phase). The primary outcome compared the proportion of patients referred to a pharmacist and those achieving a Harvey-Bradshaw Index (HBI) reduction of ≥3 points after therapy initiation. Results: 50 patients were included in the Early Phase and 43 patients in the Recent Phase. Utilization in pharmacy referrals increased from 48% (n = 24) in the Early Phase to 72% (n = 31) in the Recent Phase (P = 0.03). The proportion of patients achieving a HBI reduction of ≥3 points increased from 35% (n = 14) in the Early Phase to 51% (n = 18) in the Recent Phase (P = 0.23). Results also found a greater proportion of patients remaining steroid free in the Recent Phase compared to the Early Phase (50% vs 63%; P = 0.01) and C-reactive protein (CRP) improved significantly in the Recent Phase (-11) compared to (-3) in the Early Phase (P = 0.006). Conclusion: The utilization of pharmacists in an interdisciplinary IBD clinic increased and showed to impact patient care through improving symptom relief as seen by the achievement rate of the HBI score reduction, reducing steroid use after therapy initiation, and making clinically significant interventions.

Experience With Pre-procedural Hemostatic Medications versus Platelet Transfusion in Patients With Platelet Storage Pool Deficiency.

BackgroundStorage pool deficiency (SPD) is a rare bleeding disorder characterized by reduction in the number of delta granules within platelets, interfering with hemostasis. Current literature lacks well-designed studies from which to draw concrete conclusions regarding pre-procedural management of bleeding complications. Objective: The purpose of this study is to describe bleeding and safety outcomes of SPD patients receiving either pre-procedural platelet transfusions or platelet-sparing regimens. Methods: An exploratory retrospective cohort study was conducted among SPD patients, comparing major bleeding events between those who received platelet transfusion and those who received desmopressin, tranexamic acid, and/or aminocaproic acid within 24 hours prior to procedure. Results: Rates of major bleeding were not found to be higher among patients who received a platelet-sparing regimen [platelet-sparing: 2/25 (8%); platelet transfusion: 2/29 (6.9%); P = .99]. Incidence of non-major bleeding was higher in the platelet transfusion group, but this was not statistically significant [platelet-sparing: 0/25 (0%); platelet transfusion: 3/29 (10.3%); P = .24]. Treatment-related adverse effects were observed following 8 of 54 procedures (14.8%). Conclusion: Use of a platelet-sparing regimen was not associated with a significantly higher incidence of major or non-major bleeding events. Future prospective trials are recommended to compare outcomes between therapies.

Risk Versus Benefit of Combined Aspirin and Warfarin Therapy in Patients With Atrial Fibrillation.

PURPOSE: Guidelines have differing recommendations for aspirin use in patients with an indication for anticoagulation. The purpose of this study was to evaluate the incidence of major bleeding and thromboembolic events (TEs) in patients with atrial fibrillation (AF) receiving warfarin alone (monotherapy group) versus warfarin plus aspirin (combination therapy group). METHODS: This was a retrospective, cohort study including patients from a pharmacist-run anticoagulation clinic. Inclusion criteria were patients with AF receiving anticoagulation between January 2013 and January 2014 observed over 5 years. RESULTS: One hundred forty-two patients were included in the combination group versus 89 in monotherapy group. In the combination group, 60 (42.3%) patients were on aspirin for no apparent indication, 19 (13.4%) had stable coronary artery disease and diabetes, and 26 (18.3%) had diabetes alone. Major bleeding occurred in 21 (14.9%) patients in the combination group versus 7 (7.9%) patients in the monotherapy group (odds ratio [OR] = 2.02, 95% confidence interval [CI]: 0.78-5.91; P = .17). TE occurred in 10 (7%) patients in the combination group versus 4 (4.5%) in the monotherapy group (OR = 1.61, 95% CI: 0.44-7.24; P = .57). There was no significant difference in bleeding (P = .85) or TE (P = .37) rates between aspirin indications in the combination group. CONCLUSION: Combination therapy versus monotherapy may increase bleeding risk with little benefit in decreasing AF-related stroke or cardiovascular events.

Tolerance of Proprotein Convertase Subtilisin/Kexin type 9 (PCSK9) Inhibitors in Patients With Self-Reported Statin Intolerance.

BACKGROUND: Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors have been shown to lower atherogenic lipid markers in patients with statin intolerance; however, external validity of these findings is unclear in patients with self-reported statin intolerance. OBJECTIVE: The objective of this study was to describe the tolerability of evolocumab and alirocumab in patients with self-reported statin intolerance. Secondary objectives were to describe their efficacy and obtainability. METHODS: A retrospective chart review was completed and included adult patients with self-reported statin intolerance who were prescribed a PCSK9 inhibitor. Patient-reported side effects, laboratory values, and insurance information were collected for assessment of study objectives. RESULTS: During the study period, 55 patients were prescribed PCSK9 inhibitor, 42 started therapy, and 34 had at least 1 follow-up visit. While myalgias occurred in 14.7% (n = 5) of patients, flu-like symptoms in 11.8% (n = 4), and fatigue in 2.9% (n = 1), only 5.9% (n = 2) of prescriptions for PCSK9 inhibitors were discontinued. Low-density lipoprotein cholesterol (LDL-C) was reduced 48.7% (95% confidence interval [CI]: -1.7%-99.1%), and 20 (58.8%) patients achieved a ≥50% reduction in LDL-C. Regarding obtainability, of the 57 prescriptions written, 77.2% (n = 44) required prior authorization and 5.3% (n = 3) were denied by insurance. CONCLUSION: PCSK9 inhibitors were well tolerated in patients with self-reported statin intolerance.

Safety of Twice Daily Sotalol in Patients with Renal Impairment: A Single Center, Retrospective Review.

BACKGROUND: The class III antiarrhythmic sotalol is renally eliminated with a dose-related propensity to cause adverse drug reactions (ADR) potentially leading to life-threatening arrhythmias. Although product labeling recommends once daily dosing in patients with renal impairment, twice daily dosing is commonly utilized. This study evaluates the safety of this practice. METHODS: This retrospective, observational study examined renally impaired patients with atrial fibrillation or atrial flutter admitted for sotalol initiation from July 1, 2012 - December 31, 2014, then for up to 20 months after initiation. Primary endpoints included rates of ADR and therapy changes due to ADR. Secondary endpoints included therapy changes due to arrhythmia recurrence, admissions due to arrhythmia recurrence, and therapy changes for any cause. RESULTS: Analysis included 134 patients with an average creatinine clearance of 51 ml/min, followed over a median of 170 days. Length of stay averaged 3 days withADR occurring in 53.7% of patients, most commonly QT prolongation or bradycardia. Therapy change due to ADR occurred in 45.5% of patients (n=61). Therapy change due to arrhythmia recurrence occurred in 23.1% (n=31), admission due to arrhythmia recurrence occurred in 24.6% (n=33), and therapy change for any cause occurred in 74.6% (n=100). CONCLUSION: Initiating sotalol twice daily in renally impaired patients results in ADR and therapy change rates consistent with rates seen in clinical practice for non-renally impaired patients, with minimal length of stay.This practice may be reasonable when initiated in the acute care setting with subsequent outpatient monitoring, however further study is needed.

Statin desensitization in a patient with probable familial hypercholesterolemia.

PROBLEM OVERVIEW: With cardiovascular disease being the leading cause of morbidity and mortality in the United States, cholesterol-lowering medications have become a prominent focus of medical management and cardiovascular risk reduction, including the use of statins making them the most widely prescribed class of medications in the United States and are the cornerstone of management of hyperlipidemia. This case report describes a 29-year-old female with probable familial hypercholesterolemia (FH) who had allergic reactions to statin therapy on two separate occasions. She required statin therapy based on her elevated carotid intima media thickness test, historic LDL-C ≥ 190 mg/dL, elevated Lp(a), and family history significant for premature coronary heart disease. In this report, we document a case of successful oral desensitization to rosuvastatin and propose a replicable statin desensitization protocol. MAJOR MANAGEMENT: The patient was admitted for rosuvastatin desensitization following predetermined protocols, utilizing an interdisciplinary team, and monitored for 24 hours following completion of administration prior to discharge. She successfully completed desensitization to rosuvastatin 10mg by mouth daily without anaphylactic reaction. She continued to tolerate rosuvastatin 10mg daily through most recent follow-up, and with this addition, significant improvement in lipid levels was achieved. CONCLUSION: This case report presented a patient with probable FH who was previously intolerant to other statin therapies that underwent successful desensitization to rosuvastatin with subsequent achievement of therapy goals.

Cost-benefit and cost-savings analyses of antiarrhythmic medication monitoring.

PURPOSE: The economic impact of pharmacist-managed antiarrhythmic drug therapy monitoring on an academic medical center's electrophysiology (EP) program was investigated. METHODS: Data were collected for the initial two years of patient visits (n = 816) to a pharmacist-run clinic for antiarrhythmic drug therapy monitoring. A retrospective cost analysis was conducted to assess the direct costs associated with three appointment models: (1) a clinic office visit only, (2) a clinic visit involving electrocardiography and basic laboratory tests, and (3) a clinic visit including pulmonary function testing and chest x-rays in addition to electrocardiography and laboratory testing. A subset of patient cases (n = 18) were included in a crossover analysis comparing pharmacist clinic care and usual care in an EP physician clinic. The primary endpoints were the cost benefits and cost savings associated with pharmacy-clinic care versus usual care. A secondary endpoint was improvement of overall EP program efficiency. RESULTS: The payer mix was 61.6% (n = 498) Medicare, 33.2% (n = 268) managed care, and 5.2% (n = 42) other. Positive contribution margins were demonstrated for all appointment models. The pharmacist-managed clinic also yielded cost savings by reducing overall patient care charges by 21% relative to usual care. By the second year, the pharmacy clinic improved EP program efficiency by scheduling an average of 24 patients per week, in effect freeing up one day per week of EP physician time to spend on other clinical activities. CONCLUSION: Pharmacist monitoring of antiarrhythmic drug therapy in an out-patient clinic provided cost benefits, cost savings, and improved overall EP program efficiency.

Initial experience with antiarrhythmic medication monitoring by clinical pharmacists in an outpatient setting: a retrospective review.

BACKGROUND: Antiarrhythmic medications may be used chronically to prevent recurrences of cardiac arrhythmias. Vaughan Williams class I and class III antiarrhythmic drugs have the potential for serious adverse effects, some of which can result in significant morbidity or mortality. To provide early detection and prevention of adverse events, appropriate therapeutic monitoring has been suggested during amiodarone therapy. OBJECTIVE: The objective of this study was to monitor antiarrhythmic drug therapy to improve the continuity and consistency of care for patients receiving class I or class III antiarrhythmic drugs. METHODS: Patients receiving antiarrhythmic medications, including amiodarone, sotalol, dofetilide, and propafenone, were referred to an antiarrhythmic medications clinic (at an academic university), Columbus, Ohio, either at the time of hospital discharge or during an outpatient appointment with a cardiologist, for monitoring. A retrospective chart review was conducted in consecutive outpatients attending the clinic between July 2007 and April 2008. Antiarrhythmic medication monitoring protocols were developed for a pharmacy-based outpatient clinic by a collaborative effort between pharmacists, physicians, and nurses. Adherence to monitoring protocols was assessed, and the type and frequency of pharmacist-identified events and interventions were determined. Continuum of care for patients was facilitated by coordination of referral to specialty clinics (n = 11) or pharmacist contact with physicians (n = 40). RESULTS: In all, 134 patients were included and were receiving amiodarone (n = 58), sotalol (n = 40), dofetilide (n = 28), or propafenone (n = 8). At enrollment, 59.0% of patients had completed all recommended laboratory and objective testing compared with 98.5% after the initial visit. Adherence to monitoring protocols was improved in patients receiving amiodarone, dofetilide, or propafenone, but not sotalol. Fifty-four patients had a return visit, and after follow-up visits, 100% of patients were current with testing. Pharmacist-identified events or interventions occurred during 38% of visits, including unrecognized adverse event detection (ie, pulmonary function decline, QT prolongation, laboratory abnormality) and clinically significant drug interaction identification. Amiodarone was associated with the highest rate of detected adverse events (23% of patient visits). A change in the antiarrhythmic medication regimen was recommended for 9 patients that later resulted in the discontinuation of therapy in 3 patients. CONCLUSION: Pharmacist monitoring of outpatient antiarrhythmic medication therapy appeared to improve patient adherence to recommended testing protocols and to help identify adverse events and clinically significant drug interactions.
