Key Articles and Guidelines in the Management of Pericardial Syndromes.

Over the past two decades, emerging literature has shaped the management of pericardial syndromes and has evolved abundantly towards the creation of European guidelines for the diagnosis and management of pericardial diseases. However, since the publication of the European guidelines in 2015, more data surrounding the management of pericardial syndromes have been published. Comprehensive reference materials with the most updated literature are warranted and can be pivotal in helping pharmacists make evidence-based and clinical decisions for patients diagnosed with pericardial syndromes. This compilation of key articles and guidelines will serve as a resource for pharmacists who are responsible for the care of patients with pericardial syndromes.

Dofetilide Dose Reductions and Discontinuation in Obese Compared with Nonobese Patients.

ABSTRACT: Dofetilide is an antiarrhythmic agent and primarily eliminated renally. Initial dosing is determined by creatinine clearance, calculated by total body weight in the Cockcroft-Gault equation. To date, there is no evidence comparing the dosing of dofetilide in obese versus nonobese patients. We conducted a retrospective review of 217 adults admitted for dofetilide loading to evaluate the tolerability of dofetilide in obese versus nonobese patients. The rate of dose adjustments, including dose reductions and discontinuations, was compared between obese versus nonobese patients in unadjusted and adjusted analyses. Electrocardiograms were collected throughout the loading period, and calculation of QT intervals was performed. Obese patients did not have a significantly higher frequency of dose adjustments compared with nonobese patients (51.5% vs. 44.8%, P = 0.33). Using total body weight to determine starting doses was associated with great odds of dose adjustments compared with ideal body weight (OR 3.69, P = 0.002) and adjusted body weight (OR 4.46, P = 0.02). Men required significantly fewer dose adjustments compared with women on multivariate analysis (OR 0.53, P = 0.03). Obesity is not associated with an increase in the rate of dose adjustments. Total body weight should be used with caution to calculate initial doses of dofetilide in women because it may lead to a higher rate of dose adjustments compared with ideal body weight. Additional studies are needed to confirm the optimal method for selecting starting doses of dofetilide in women, particularly those with a body mass index of ≥30.

Development of a pharmacy resident rotation to expand decentralized clinical pharmacy services.

PURPOSE: The development of a pharmacy resident rotation to expand decentralized clinical pharmacy services is described. SUMMARY: In an effort to align with the initiatives proposed within the ASHP Practice Advancement Initiative, the department of pharmacy at Cleveland Clinic, a 1,400-bed academic, tertiary acute care medical center in Cleveland, Ohio, established a goal to provide decentralized clinical pharmacy services for 100% of patient care units within the hospital. Patient care units that previously had no decentralized pharmacy services were evaluated to identify opportunities for expansion. Metrics analyzed included number of medication orders verified per hour, number of pharmacy dosing consultations, and number of patient discharge counseling sessions. A pilot study was conducted to assess the feasibility of this service and potential resident learning opportunities. A learning experience description was drafted, and feedback was solicited regarding the development of educational components utilized throughout the rotation. Pharmacists who were providing services to similar patient populations were identified to serve as preceptors. Staff pharmacists were deployed to previously uncovered patient care units, with pharmacy residents providing decentralized services on previously covered areas. A rotating preceptor schedule was developed based on geographic proximity and clinical expertise. An initial postimplementation assessment of this resident-driven service revealed that pharmacy residents provided a comparable level of pharmacy services to that of staff pharmacists. Feedback collected from nurses, physicians, and pharmacy staff also supported residents' ability to operate sufficiently in this role to optimize patient care. CONCLUSION: A learning experience developed for pharmacy residents in a large medical center enabled the expansion of decentralized clinical services without requiring additional pharmacist full-time equivalents.

The use of anti-factor Xa monitoring in a selection of patients receiving enoxaparin at a large academic medical center.

Therapeutic enoxaparin is commonly used over heparin because of its favorable pharmacokinetic profile and ease of administration. Monitoring of the anticoagulant response, if necessary, is done with anti-factor Xa levels. Currently, it is suggested that monitoring may be beneficial in patients who are overweight and those with renal dysfunction. This study aimed to characterize the use of enoxaparin at a large-academic medical center in patients >150 kg, <45 kg and in those with renal dysfunction, and to describe the rate of anti-factor Xa monitoring in these patients. There were 273 patients included in the study: n = 96 for <45 kg arm, n = 111 for >150 kg arm and n = 66 for renal dysfunction arm. Less than 30 % of patients in each arm had low molecular weight heparin anti-factor Xa levels drawn. Of these only half were drawn as peak levels (4 h post dose). Overall rates of anti-factor Xa monitoring was low. It was found that obese patients achieved therapeutic anticoagulation with lower than recommended doses; underweight patients were often subtherapeutic on the recommended doses; and patients with renal dysfunction tended to have therapeutic to subtherapeutic anti-factor Xa levels. Ultimately, this evaluation showed that enoxaparin has unpredictable pharmacokinetics in these three high-risk patient populations and anti-factor Xa monitoring may be necessary to ensure therapeutic levels and appropriate dosing.
