Bridging the Gap Between Clinical Practice and the AACN Practice Alert on Pulmonary Artery/Central Venous Pressure Monitoring in Adults.

Measuring and documenting accurate data from pulmonary artery and central venous pressure catheters is an important responsibility of critical care nurses. The American Association of Critical-Care Nurses Practice Alert titled Pulmonary Artery/Central Venous Pressure Monitoring in Adults provides evidence-based standards against which nurses can compare their practice related to obtaining valid hemodynamic data. Identifying and acting on improvement opportunities is also a nursing responsibility and helps to ensure that patients with pulmonary artery or central venous pressure catheters receive high-quality care. This article reviews various strategies to compare nursing practice to the Pulmonary Artery/Central Venous Pressure Monitoring in Adults Practice Alert and to close identified gaps in clinical practice.

Delirium in Trauma Patients: Prevalence and Predictors.

BACKGROUND: Delirium is associated with increased mortality, morbidity, hospital costs, and postdischarge cognitive dysfunction. Most research focuses on nontrauma patients receiving mechanical ventilation in the intensive care unit. OBJECTIVES: To determine the prevalence and predictors of delirium in trauma patients residing in intensive and intermediate care units of an academic medical center. METHODS: Trauma patients were screened for delirium by using the Confusion Assessment Method for the Intensive Care Unit. Exclusion criteria included documented brain injury, history of psychosis or cognitive impairment, not speaking English, and hearing or vision loss. RESULTS: Of the 215 study patients, 24% were positive for delirium; 36% of patients in the intensive care unit and 11% of patients in the intermediate care unit. Delirium-positive patients were older (mean age, 53.4 years) than patients who were not (mean age, 44 years; P = .004). Although mechanical ventilation (odds ratio, 4.73, P = .004) was the strongest independent risk factor for delirium, 12% of delirium-positive patients were not receiving mechanical ventilation. Other predictors of delirium were use of antipsychotic medications, higher scores on the Acute Physiology and Chronic Health Evaluation III, and lower scores on the Richmond Agitation-Sedation Scale. CONCLUSIONS: Patients in both the intermediate and intensive care units, whether mechanical ventilation was used or not, were positive for delirium. Delirium prevention protocols may benefit trauma patients regardless of their inpatient location.

Using Procalcitonin in Septic Shock to Guide Antibacterial Therapy.

Over the last decade, the biomarkers procalcitonin and C-reactive protein have gained interest in sepsis research. Procalcitonin is a unique biomarker that is specific to bacterial infection and has demonstrated utility in the risk stratification of patients with potential life-threatening bacterial infections. In addition, procalcitonin has been documented as having a role in reducing the rate of unnecessary antibiotics while positively impacting antibiotic resistance rates and cost savings. The purposes of this review article are to discuss the clinical relevance of C-reactive protein and procalcitonin as diagnostic and prognostic markers for sepsis with a focus on the use of serial procalcitonin levels as a component of antibiotic stewardship programs. The federal government has recently become invested in combating the progression of antibiotic resistance; a 5-year national plan has been developed to address these concerns. Establishing a reliable antibiotic stewardship program is one of the goals of this national plan.

Secondary traumatic stress in trauma nurses: prevalence and exposure, coping, and personal/environmental characteristics.

The purpose of this study is to determine the incidence of secondary traumatic stress (STS) in nurses who primarily care for trauma patients. A demographic/behavioral survey and Penn Inventory to measure the presence of STS were distributed to 262 nurses in a level I trauma center. Relationships between STS and years of experience, coping strategies, and personal and environmental characteristics were examined. Response rate was 49%. The median Penn Inventory score was 17.5. Nine nurses (7%) scored 35 or more, reflecting STS. Those with STS had fewer years of nursing experience and in trauma nursing, were more likely to use medicinals, and had fewer and weaker support systems.

The use of benchmarking to identify top performing critical care units: a preliminary assessment of their policies and practices.

PURPOSE: To describe the policies and practices of intensive care units (ICUs) with good patient survival and highly efficient resource use and to identify relevant variables for future investigation. MATERIALS AND METHODS: We used clinical data for 359,715 patients from 108 ICUs to compare the ratios of actual with Acute Physiology and Chronic Health Evaluation (APACHE) III predicted hospital mortality, ICU and hospital stay, and the proportion of low-risk monitor patients. The best performing ICUs (top 10%) were defined by a mortality ratio of 1.0 or less, and either the lowest ratio for ICU stay, hospital stay, or percentage of low-risk monitor patients. The medical and nursing directors of top performing ICUs completed a questionnaire to describe their unit's structure policies and practices. RESULTS: Among the 108 ICUs, 61 (56%) had a ratio of actual to predicted hospital mortality of 1.0 or less and the best performing units had ICU stay ratios of 0.62 to 0.79, hospital stay ratios of 0.73 to 0.77, and admitted 10% to 38% low-risk monitor patients. ICU structure varied among the best performing ICUs. Units with the shortest ICU and hospital stay had alternatives to intensive care, methods to facilitate patient throughput, used multiple protocols for high-volume diagnoses and care processes, and continuously monitored resource use. Units with the fewest low-risk monitor patients screened potential admissions, had intermediate care areas, extended-stay recovery rooms, and care pathways for high-volume diagnoses. CONCLUSIONS: Benchmarking can be used to identify ICUs with good patient survival and highly efficient resource use. The combination of policies and practices used by these units might improve resource use in other ICUs.

Coagulopathies in trauma patients.

Coagulopathy after traumatic injury has multiple etiologies. It may result from overwhelming activation of tissue factor, consumption of circulating coagulation proteins, massive transfusion, metabolic alterations, hypothermia, or any combination of these factors. Despite advances in trauma resuscitation, the problem of persistent, life-threatening coagulopathy continues to pose a significant challenge for the healthcare team, and sometimes is an insurmountable obstacle in the path to recovery of the patient with trauma. Development of a coagulopathy has a significant impact on the morbidity and mortality of the patient with trauma. This article describes the relevant pathophysiology as it relates to the development of a coagulopathy, prevention strategies, and management principles applied in caring for the patient with trauma and a coagulopathy.
