Major publications in the critical care pharmacotherapy literature: January-December 2017.

PURPOSE: To summarize selected meta-analyses and trials related to critical care pharmacotherapy published in 2017. The Critical Care Pharmacotherapy Literature Update (CCPLU) Group screened 32 journals monthly for impactful articles and reviewed 115 during 2017. Two meta-analyses and eight original research trials were reviewed here from those included in the monthly CCPLU. Meta-analyses on early, goal-directed therapy for septic shock and statin therapy for acute respiratory distress syndrome were summarized. Original research trials that were included evaluate thrombolytic therapy in severe stroke, hyperoxia and hypertonic saline in septic shock, intraoperative ketamine for prevention of post-operative delirium, intravenous ketorolac dosing regimens for acute pain, angiotensin II for vasodilatory shock, dabigatran reversal with idarucizumab, bivalirudin versus heparin monotherapy for myocardial infarction, and balanced crystalloids versus saline fluid resuscitation. CONCLUSION: This clinical review provides perspectives on impactful critical care pharmacotherapy publications in 2017.

Major publications in the critical care pharmacotherapy literature: February 2012 through February 2013.

PURPOSE: Recent impactful additions to the professional literature on the role of pharmacotherapy in treating the critically ill are summarized. SUMMARY: An unusually large number of updated practice guidelines and other publications with broad critical care pharmacotherapy ramifications appeared in the primary biomedical literature during the designated review period (February 2012-February 2013). Hundreds of relevant articles were evaluated by the Critical Care Pharmacotherapy Literature Update group (CCPLU), a national group of pharmacists who routinely monitor 25 peer-reviewed journals for emerging evidence that pertains to rational medication use in the intensive care unit (ICU) setting. From among those articles, 64 were summarized for dissemination to CCPLU members; the 8 publications deemed to have the greatest utility for critical care practitioners, as determined by CCPLU through a voting process, were selected for inclusion in this review, with preference given to evidence meeting high standards of methodological quality. The summaries presented here include (1) important new recommendations on management of pain, agitation, and delirium in critically ill patients, (2) a comprehensive update of a practice guideline issued in 2008 by the Surviving Sepsis Campaign, (3) novel strategies for the prevention and/or treatment of hyperglycemia in critical care, and (4) reports on clinical trials of promising alternative methods of sedation for use in weaning patients from mechanical ventilation. CONCLUSION: This review provides synopses of practice guidelines and other recent additions to the professional literature pertaining to rational medication use in the ICU practice setting.

Acute care clinical pharmacy practice: unit- versus service-based models.

This commentary from the 2010 Task Force on Acute Care Practice Model of the American College of Clinical Pharmacy was developed to compare and contrast the "unit-based" and "service-based" orientation of the clinical pharmacist within an acute care pharmacy practice model and to offer an informed opinion concerning which should be preferred. The clinical pharmacy practice model must facilitate patient-centered care and therefore must position the pharmacist to be an active member of the interprofessional team focused on providing high-quality pharmaceutical care to the patient. Although both models may have advantages and disadvantages, the most important distinction pertains to the patient care role of the clinical pharmacist. The unit-based pharmacist is often in a position of reacting to an established order or decision and frequently is focused on task-oriented clinical services. By definition, the service-based clinical pharmacist functions as a member of the interprofessional team. As a team member, the pharmacist proactively contributes to the decision-making process and the development of patient-centered care plans. The service-based orientation of the pharmacist is consistent with both the practice vision embraced by ACCP and its definition of clinical pharmacy. The task force strongly recommends that institutions pursue a service-based pharmacy practice model to optimally deploy their clinical pharmacists. Those who elect to adopt this recommendation will face challenges in overcoming several resource, technologic, regulatory, and accreditation barriers. However, such challenges must be confronted if clinical pharmacists are to contribute fully to achieving optimal patient outcomes.

Aminoglycoside pharmacokinetic parameters in neurocritical care patients undergoing induced hypothermia.

STUDY OBJECTIVE: To determine the effects of mild-to-moderate induced hypothermia-a neuroprotectant and/or therapeutic strategy for the management of intracranial hypertension in neurologically injured patients-on the pharmacokinetics of aminoglycoside therapy. DESIGN: Pharmacokinetic analysis. SETTING: Critical care unit at a university-affiliated hospital. PATIENTS: Three patients, aged 22, 24, and 47 years, who received tobramycin and had documented tobramycin levels while undergoing induced hypothermia for more than 24 hours for intracranial hypertension. MEASUREMENTS AND MAIN RESULTS: For each of the three patients, predicted pharmacokinetic parameters (volume of distribution, first-order elimination rate constant, half-life, and renal drug clearance) based on population data were compared with their actual pharmacokinetic parameters that were calculated based on observed tobramycin serum levels. All three patients had a normal creatinine clearance, estimated according to established methods. When pharmacokinetic parameters were calculated after the first tobramycin dose using a one-compartment method, all patients had a slower first-order elimination rate and a larger volume of distribution compared with predicted population estimates. CONCLUSION: These findings suggest that induced hypothermia may result in impaired elimination of aminoglycosides. Caution should be exercised when attempting to use predicted pharmacokinetic parameters to dose aminoglycosides in this patient population, and first-dose pharmacokinetics should be considered to optimize the dose and dosing interval early in the course of therapy. Further investigation of this phenomenon with greater numbers of patients are needed to confirm these findings and to determine optimal dosing strategies of aminoglycosides in patients undergoing induced hypothermia.
