Interprofessional Care and Teamwork in the ICU.

OBJECTIVES: We describe the importance of interprofessional care in modern critical care medicine. This review highlights the essential roles played by specific members of the interprofessional care team, including patients and family members, and discusses quality improvement initiatives that require interprofessional collaboration for success. DATA SOURCES: Studies were identified through MEDLINE search using a variety of search phrases related to interprofessional care, critical care provider types, and quality improvement initiatives. Additional articles were identified through a review of the reference lists of identified articles. STUDY SELECTION: Original articles, review articles, and systematic reviews were considered. DATA EXTRACTION: Manuscripts were selected for inclusion based on expert opinion of well-designed or key studies and review articles. DATA SYNTHESIS: "Interprofessional care" refers to care provided by a team of healthcare professionals with overlapping expertise and an appreciation for the unique contribution of other team members as partners in achieving a common goal. A robust body of data supports improvement in patient-level outcomes when care is provided by an interprofessional team. Critical care nurses, advanced practice providers, pharmacists, respiratory care practitioners, rehabilitation specialists, dieticians, social workers, case managers, spiritual care providers, intensivists, and nonintensivist physicians each provide unique expertise and perspectives to patient care, and therefore play an important role in a team that must address the diverse needs of patients and families in the ICU. Engaging patients and families as partners in their healthcare is also critical. Many important ICU quality improvement initiatives require an interprofessional approach, including Awakening and Breathing Coordination, Delirium, Early Exercise/Mobility, and Family Empowerment bundle implementation, interprofessional rounding practices, unit-based quality improvement initiatives, Patient and Family Advisory Councils, end-of-life care, coordinated sedation awakening and spontaneous breathing trials, intrahospital transport, and transitions of care. CONCLUSIONS: A robust body of evidence supports an interprofessional approach as a key component in the provision of high-quality critical care to patients of increasing complexity and with increasingly diverse needs.

Preventing Harm in the ICU-Building a Culture of Safety and Engaging Patients and Families.

OBJECTIVE: Preventing harm remains a persistent challenge in the ICU despite evidence-based practices known to reduce the prevalence of adverse events. This review seeks to describe the critical role of safety culture and patient and family engagement in successful quality improvement initiatives in the ICU. We review the evidence supporting the impact of safety culture and provide practical guidance for those wishing to implement initiatives aimed at improving safety culture and more effectively integrate patients and families in such efforts. DATA SOURCES: Literature review using PubMed including evaluation of key studies assessing large-scale quality improvement efforts in the ICU, impact of safety culture on patient outcomes, methodologies for quality improvement commonly used in healthcare, and patient and family engagement. Print and web-based resources from leading patient safety organizations were also searched. STUDY SELECTION: Our group completed a review of original studies, review articles, book chapters, and recommendations from leading patient safety organizations. DATA EXTRACTION: Our group determined by consensus which resources would best inform this review. DATA SYNTHESIS: A strong safety culture is associated with reduced adverse events, lower mortality rates, and lower costs. Quality improvement efforts have been shown to be more effective and sustainable when paired with a strong safety culture. Different methodologies exist for quality improvement in the ICU; a thoughtful approach to implementation that engages frontline providers and administrative leadership is essential for success. Efforts to substantively include patients and families in the processes of quality improvement work in the ICU should be expanded. CONCLUSIONS: Efforts to establish a culture of safety and meaningfully engage patients and families should form the foundation for all safety interventions in the ICU. This review describes an approach that integrates components of several proven quality improvement methodologies to enhance safety culture in the ICU and highlights opportunities to include patients and families.

Effect of an electronic medical record alert for severe sepsis among ED patients.

BACKGROUND: Severe sepsis and septic shock are a major health concern worldwide. The objective of this study is to determine if Severe Sepsis Best Practice Alert (SS-BPA) implementation was associated with improved processes of care and clinical outcomes among patients with severe sepsis or septic shock presenting to the emergency department (ED). METHODS: This is a single-center, before-and-after observational study. The intervention group (n = 103) consisted of adult patients presenting to the ED with severe sepsis or septic shock during a 7-month period after implementation of the SS-BPA. The control group (n = 111) consisted of patients meeting the same criteria over a prior 7-month period. The SS-BPA primarily acts by automated, real-time, algorithm-based detection of severe sepsis or septic shock via the electronic medical record system. The primary outcome was in-hospital mortality. Secondary outcomes included hospital length of stay (LOS), time to antibiotic administration, and proportion of patients who received antibiotics within the target 60 minutes. RESULTS: Time to antibiotics was significantly reduced in the SS-BPA cohort (29 vs 61.5 minutes, P < .001). In addition, there was a higher proportion of patients who received antibiotics within 60 minutes (76.7 vs 48.6%; P < .001). On multivariable analysis, in-hospital mortality was not significantly reduced in the intervention group (odds ratio, 0.64; 95% confidence interval, 0.26-1.57). Multivariable analysis of LOS indicated a significant reduction among patients in the SS-BPA cohort (geometric mean ratio, 0.66; 95% confidence interval, 0.53-0.82). CONCLUSION: Implementation of the SS-BPA for severe sepsis or septic shock among ED patients is associated with significantly improved timeliness of antibiotic administration and reduced hospital LOS.

Clopidogrel treatment and the incidence and severity of community acquired pneumonia in a cohort study and meta-analysis of antiplatelet therapy in pneumonia and critical illness.

Platelet activation results in the release and upregulation of mediators responsible for immune cell activation and recruitment, suggesting that platelets play an active role in immunity. Animal models and retrospective data have demonstrated benefit of antiplatelet therapy on inflammatory mediator expression and clinical outcomes. This study sought to characterize effects of clopidogrel on the incidence and severity of community-acquired pneumonia (CAP). A retrospective cohort study was conducted of Kentucky Medicaid patients (2001-2005). The exposed cohort consisted of patients receiving at least six consecutive clopidogrel prescriptions; the non-exposed cohort was comprised of patients not prescribed clopidogrel. Primary endpoints included incidence of CAP and inpatient treatment. Secondary severity endpoints included mortality, intensive care unit admission, mechanical ventilation, sepsis, and acute respiratory distress syndrome/acute lung injury. CAP incidence was significantly greater in the exposed cohort (OR 3.39, 95% CI 3.27-3.51, p < 0.0001) that remained after adjustment (OR 1.48, 95% CI 1.41-1.55, p < 0.0001). Inpatient treatment was more common in the exposed cohort (OR 1.96, 95% CI 1.85-2.07, p < 0.0001), but no significant difference remained after adjustment. Trends favoring the exposed cohort were found for the secondary severity endpoints of mechanical ventilation (p = 0.07) and mortality (p = 0.10). Pooled analysis of published studies supports these findings. While clopidogrel use may be associated with increased CAP incidence, clopidogrel does not appear to increase--and may reduce--its severity among inpatients. Because this study was retrospective and could not quantify all variables (e.g., aspirin use), these findings should be explored prospectively.

Considerations for Medication Management and Anticoagulation During Continuous Renal Replacement Therapy.

Providing safe and high-quality care to critically ill patients receiving continuous renal replacement therapy (CRRT) includes adequate drug dosing and evaluation of patients' response to medications during therapy. Pharmacokinetic drug studies in acute kidney injury and CRRT are limited, considering the number of medications used in critical care. Therefore, it is important to understand the basic principles of drug clearance during CRRT by evaluating drug properties, CRRT modalities, and how they affect medication clearance. Few published studies have addressed drug disposition and clinical response during CRRT. Additionally, clotting in the CRRT circuit is a concern, so a few options for anticoagulation strategies are presented. This article reviews (1) the CRRT system and drug property factors that affect medication management, (2) the evidence available to guide drug dosing, and (3) anticoagulation strategies for critically ill patients receiving CRRT.

Value of pharmacy residency training: a survey of the academic medical center perspective.

PURPOSE: The results of a survey assessing the views of pharmacy directors, medical center executives, and pharmacists on the value of residency programs to their institutions are reported. METHODS: In a two-phase survey entailing face-to-face interviews and the use of an electronic questionnaire, representatives of the pharmacy departments and executive staffs of eight academic medical centers were asked to rate the impact of pharmacy residency programs in areas such as educational and research innovation, quality-of-care and cost outcomes, and opportunities for revenue generation. RESULTS: Seven hospital administrators, eight directors of pharmacy, 122 pharmacists serving as residency preceptors, and 91 nonpreceptor pharmacists participated in the survey. The survey responses indicated that hospital administrators view pharmacy residency programs as important contributors to their institutions' prestige, academic success, and capacity for delivering educational programs. All directors of pharmacy surveyed were in agreement that the costs associated with conducting a pharmacy residency program are outweighed by the cost savings achieved through resident contributions to patient care and medication error prevention. A large majority (90%) of preceptor pharmacists agreed or strongly agreed that residents help reduce medication errors by educating prescribers and other activities that promote rational medication use; only about half of nonpreceptor pharmacists shared that view, although 65% of nonpreceptors acknowledged the contributions of residents to overall pharmacy department success. CONCLUSION: All groups of survey respondents viewed residency programs as important assets to their institutions, especially in the areas of institutional prestige, staff recruitment, and professional development and education.

Platelets as immune mediators: their role in host defense responses and sepsis.

Platelets occupy a central role at the interface between thrombosis and inflammation. At sites of vascular damage, adherent platelets physically and functionally interact with circulating leukocytes. Activated platelets release soluble factors into circulation that may have local and systemic effects on blood and vascular cells. Platelets can also interact with a wide variety of microbial pathogens. Emerging evidence from animal models suggests that platelets may participate in a wide variety of processes involving tissue injury, immune responses and repair that underlie diverse diseases such as atherosclerosis, autoimmune disorders, inflammatory lung and bowel disorders, host-defense responses and sepsis. In this review, we summarize the general mechanisms by which platelets may contribute to immune function, and then discuss evidence for their role in host defense responses and sepsis from preclinical and clinical studies.

Contemporary pharmacologic issues in the management of traumatic brain injury.

Traumatic brain injury (TBI) is a major cause of death and disability in the United States. While there are no pharmacotherapeutic options currently available for attenuating the neurologic injury cascade after TBI, numerous pharmacologic issues are encountered in these critically ill patients. Adequate fluid resuscitation, reversal of coagulopathy, maintenance of cerebral perfusion, and treatment of intracranial hypertension are common interventions early in the treatment of TBI. Other deleterious complications such as venous thromboembolism, extremes in glucose concentrations, and stress-related mucosal disease should be anticipated and avoided. Early provision of nutrition and prevention of drug or alcohol withdrawal are also cornerstones of routine care in TBI patients. Prevention of infections and seizures may also be helpful. Clinicians caring for TBI patients should be familiar with the pharmacologic issues typical of this vulnerable population in order to develop optimal strategies of care to anticipate and prevent common complications.

Current controversies in critical illness-related corticosteroid insufficiency and glucocorticoid supplementation.

The stress response, which is triggered by a number of factors, including surgery, results in activation of the hypothalamic pituitary adrenal axis and subsequent release of cortisol from the adrenal glands. Critical illness-related corticosteroid insufficiency is an inadequate corticosteroid response relative to a patient's illness; patients with critical illness-related corticosteroid insufficiency have both insufficient circulating cortisol and impaired cellular use of glucocorticoids. Corticosteroids, such as hydrocortisone, have been cited to improve survival, oxygenation, duration of mechanical ventilation, and intensive care unit-free days in critically ill patients. Perioperative glucocorticoid supplementation is also recommended in patients with secondary adrenal insufficiency due to chronic corticosteroid use.
