Retrospective Evaluation of Commonly Used Equations to Predict Energy Expenditure in Mechanically Ventilated, Critically Ill Patients

Study Objective. To determine which of four commonly used equations to estimate energy expenditure is precise and unbiased compared with energy expenditure as measured by indirect calorimetry.

Impact of a Clinical Pharmacy Admission Medication Reconciliation Program on Medication Errors in “High-Risk” Patients

Background: Medication errors are common upon hospital admission. Clinical pharmacist involvement in medication reconciliation is effective in identifying and rectifying medication errors. However, data is lacking on the economic impact, time requirements, and severity of errors resolved by clinical pharmacists. Objective: To determine the incidence of unintended admission medication discrepancies resolved by clinical pharmacists. Secondary objectives were to determine the type of discrepancies, potential severity, proximal cause, and economic impact of this clinical pharmacy program. Methods: This was a single-center, prospective, observational study conducted at a major teaching medical institution. Following institutional review board approval, data collection was conducted over a 4-week period (August 22, 2011, to September 16, 2011). Descriptive statistical methods were performed for all data analyses. Results: A total of 517 patients involving 5006 medications were included in this study. More than 25% (n = 132) of patients had at least 1 error associated with a medication ordered on hospital admission. Pharmacists resolved a total of 467 admission medication errors (3.5 ± 2.3 errors/patient). The most common type of medication error resolved was medication omission (79.6%). In regard to severity, 46% of medication errors were considered significant or serious. Overall, the mean total time was 44.4 ± 21.8 minutes per medication reconciliation. This clinical pharmacy program was estimated to carry a net present value of

Bovine hemoglobin: a nontraditional approach to the management of acute anemia in a Jehovah's Witness patient with autoimmune hemolytic anemia.

5.7 million over 5 years. Conclusion: Clinical pharmacist involvement within a multidisciplinary health care team during the admission medication reconciliation process demonstrated a significant improvement in patient safety and an economic benefit.

Prevention, recognition, and management of delirium in the intensive care unit.

Introduction: Management of severe symptomatic anemia in critically ill Jehovah’s Witness patients remains a challenge. The paucity of therapeutic alternatives to human red blood cells has prompted the use of blood substitutes. Case Report: A 19-year-old female Jehovah’s Witness patient presented to the emergency department following several episodes of syncope. She was found to have a positive Coombs test and was diagnosed with warm-bodied autoimmune hemolytic anemia. Upon admission, her hemoglobin was 8.4 g/dL, then dropped to a nadir of 2.8 g/dL 4 days later. She received traditional management with corticosteroids, intravenous immune globulin, rituximab, and partial splenic artery embolization. Despite these therapies, hemoglobin levels failed to respond, and she experienced signs of marked ischemia. A decision was made to give 2 units of Hemopure, a bovine hemoglobin-based oxygen carrier, and the hemoglobin levels increased to 8.7 g/dL 10 days later. The patient’s overall clinical condition improved leading to subsequent hospital discharge. Conclusion: This case exemplifies the ingenuity that health care practitioners must use in critical situations involving the medical management of anemic Jehovah’s Witness patients who refuse blood products. Hemopure was used as “bridging treatment” to help save a patient from the devastating effects of ischemia resulting from severe anemia.

Practice Management Training in the PGY1 Residency Year: Best Practices from Two Nationwide Surveys:

T inten sive care unit (ICU) can be a stressful and intimidating environment for critically ill patients. Behavioral disturbances in critically ill patients may be detrimental to the safety of patients and the nurses caring for these patients. These disturbances may manifest as ICU delirium. The development of ICU delirium can lead to dire consequences, such as an increased risk of 6-month mortality, extended ICU and hospital lengths of stay, and long-term cognitive impairment.1–4 Critical care nurses caring for delirious patients are often the first to notice any changes in mental status or behavior; therefore, it is important for critical care nurses to have an understanding of ICU delirium. This review focuses on the prevention and recognition of delirium and provides an overview of both nonpharmacological and pharmacological methods of managing ICU delirium.

Patient Case Impact of Smoking Cessation on International Normalized Ratio

Purpose The development of future pharmacy leaders is vital to the advancement of our profession. Postgraduate year 1 (PGY1) residency training requires residents to exercise leadership and practice management skills. Two national surveys were conducted to describe the current state of practice management experiences and elucidate best practice recommendations. Methods The surveys, online multiple choice and free response, queried American Society of Health-System Pharmacists (ASHP)–accredited residency program practice management preceptors (survey 1) and PGY1 residents (survey 2) and were distributed via the ASHP residency program directors’ listserv. Responses were reviewed and analyzed by members of the University HealthSystem Consortium Pharmacy Council Strategic Initiatives and Programming Committee. Results Survey 1, completed by 240 institutions, identified that a combination of concentrated and longitudinal practice management experiences were used most frequently (47%), followed by concentrated alone (33%). Universally noted activities included meeting attendance (98%), projects (94%), and committee involvement (92%). Sixty-seven percent of the programs changed the experience in the previous 3 years, with 43% planning changes in the coming year. Survey 2 was completed by 58 PGY1 residents from 42 programs. Most (80%) residents stated they had enough time with their preceptors, and 55% rated their enjoyment of the rotation as 4 or 5 on a 1 to 5 scale (5 = most enjoyed) Conclusion Our findings suggest that there is not a best practice for the structure or content of the PGY1 practice management experience. These results highlight key recommendations, including the need for practice management-specific preceptor development, incorporation of longitudinal experiences, and more practice management and leadership activities.

Leadership and effective succession planning in health-system pharmacy departments

Introduction: The concurrent use of cigarettes while on warfarin therapy is a common occurrence. Smoking cessation among patients on chronic warfarin therapy is suspected to reduce drug clearance that may require dose adjustments. This type of interaction is particularly important when dealing with narrow therapeutic medications, as is the case with warfarin. Our case describes a series of supratherapeutic international normalized ratios (INRs) due to smoking cessation while on concomitant warfarin therapy. Patient Case: A 51-year-old male presented to the anticoagulation clinic for management of his warfarin therapy for an acute deep vein thrombosis. After 2 months of stable, therapeutic INR levels, the patient abruptly decreased his smoking from 1 pack/day to one-half pack/day and then subsequently stopped smoking completely. The patient’s smoking cessation resulted in a major modification of his required weekly warfarin dose to maintain a therapeutic INR (a 39% dose reduction). Conclusion: This case exemplifies how certain lifestyle factors, such as smoking, can alter the pharmacokinetics of patients on chronic warfarin therapy. This is the first case to demonstrate a greater than 30% reduction in the weekly warfarin dose following smoking cessation.

Evaluation of Recombinant Factor VIIa Off-Label Use at an Acute Care Hospital With Established Guidelines for Use

Leadership succession planning is crucial to the continuity of the comprehensive vision of the hospital pharmacy department. Leadership development is arguably the main component of training and preparing pharmacists to assume managerial positions. Succession planning begins with a review of the organizational chart in the context of the institutions strategic plan. Then career ladders are developed and key positions that require succession plans are identified. Employee profiles and talent inventory should be performed for all employees to identify education, talent, and experience, as well as areas that need improvement. Employees should set objective goals that align with the departments strategic plan, and management should work collaboratively with employees on how to achieve their goals within a certain timeframe. The succession planning process is dynamic and evolving, and periodic assessments should be conducted to determine how improvements can be made. Succession planning can serve as a marker for the success of hospital pharmacy departments.

Delirium in the intensive care unit: medications as risk factors.

Purpose At present, there are a scarcity of data available evaluating off-label prescribing patterns of recombinant factor VIIa (rFVIIa), pharmacoeconomic impact, and patient outcomes in clinical practice in an acute care setting with guidelines in place to influence prescribing practices. The primary objective of this study was to retrospectively evaluate the off-label usage and prescribing patterns of rFVIIa at a large acute care hospital with established rFVIIa guidelines. Results During the study period, a total of 199 patients were ordered rFVIIa, of which 181 (91%) received at least one dose of rFVIIa for an off-label use (n=181). Refractory bleeding and intracerebral hemorrhage were the 2 leading uses for rFVIIa, accounting for 30% (n = 54) and 29% (n = 51) of all uses, respectively. Overall, the mean number of doses per patient for all uses was 1.79. The mean number of doses per patient by non–FDA-approved use was highest in patients with cardiac surgery and refractory bleeding. The total yearly acquisition of rFVIIa for the study institution has decreased from 5.25 mcg/patient-day in 2005 to 2.52 mcg/patient-day in 2009. Conclusion The findings are encouraging and support the impact that education of pharmacy, nursing, and physician staff along with guideline development may have on off-label rFVIIa usage. Further research evaluating the impact of rFVIIa guidelines and/or order sets is warranted.
