RESUMEN
BACKGROUND: Interventions that lead to earlier liberation from mechanical ventilation can improve patient outcomes. This guideline, a collaborative effort between the American Thoracic Society and the American College of Chest Physicians, provides evidence-based recommendations to optimize liberation from mechanical ventilation in critically ill adults. METHODS: Two methodologists performed evidence syntheses to summarize available evidence relevant to key questions about liberation from mechanical ventilation. The methodologists appraised the certainty in the evidence (i.e., the quality of evidence) using the Grading of Recommendations, Assessment, Development, and Evaluation approach and summarized the results in evidence profiles. The guideline panel then formulated recommendations after considering the balance of desirable consequences (benefits) versus undesirable consequences (burdens, adverse effects, and costs), the certainty in the evidence, and the feasibility and acceptability of various interventions. Recommendations were rated as strong or conditional. RESULTS: The guideline panel made four conditional recommendations related to rehabilitation protocols, ventilator liberation protocols, and cuff leak tests. The recommendations were for acutely hospitalized adults mechanically ventilated for more than 24 hours to receive protocolized rehabilitation directed toward early mobilization, be managed with a ventilator liberation protocol, be assessed with a cuff leak test if they meet extubation criteria but are deemed high risk for postextubation stridor, and be administered systemic steroids for at least 4 hours before extubation if they fail the cuff leak test. CONCLUSIONS: The American Thoracic Society/American College of Chest Physicians recommendations are intended to support healthcare professionals in their decisions related to liberating critically ill adults from mechanical ventilation.

BACKGROUND: This clinical practice guideline addresses six questions related to liberation from mechanical ventilation in critically ill adults. It is the result of a collaborative effort between the American Thoracic Society and the American College of Chest Physicians. METHODS: A multidisciplinary panel posed six clinical questions in a Population, Intervention, Comparator, and Outcomes format. A comprehensive literature search and evidence synthesis was performed for each question, which included appraising the certainty in the evidence (i.e., the quality of evidence) using the Grading of Recommendations, Assessment, Development, and Evaluation approach. The Evidence-to-Decision framework was applied to each question, requiring the panel to evaluate and weigh the importance of the problem, the confidence in the evidence, the certainty about how much the public values the main outcomes, the magnitude and balance of desirable and undesirable outcomes, the resources and costs associated with the intervention, the impact on health disparities, and the acceptability and feasibility of the intervention. RESULTS: Evidence-based recommendations were formulated and graded initially by subcommittees and then modified after full-panel discussions. The recommendations were confirmed by confidential electronic voting; approval required that at least 80% of the panel members agree with the recommendation. CONCLUSIONS: The panel provides recommendations regarding liberation from mechanical ventilation. The details regarding the evidence and rationale for each recommendation are presented in the American Journal of Respiratory and Critical Care Medicine and Chest.

OBJECTIVE: To develop and implement an objective, reliable approach to surveillance for ventilator-associated events in adult patients. DESIGN: The Centers for Disease Control and Prevention (CDC) convened a Ventilator-Associated Pneumonia (VAP) Surveillance Definition Working Group in September 2011. Working Group members included representatives of stakeholder societies and organizations and federal partners. MAIN RESULTS: The Working Group finalized a three-tier, adult surveillance definition algorithm for ventilator-associated events. The algorithm uses objective, readily available data elements and can identify a broad range of conditions and complications occurring in mechanically ventilated adult patients, including but not limited to VAP. The first tier definition, ventilator-associated condition (VAC), identifies patients with a period of sustained respiratory deterioration following a sustained period of stability or improvement on the ventilator, defined by changes in the daily minimum fraction of inspired oxygen or positive end-expiratory pressure. The second tier definition, infection-related ventilator-associated complication (IVAC), requires that patients with VAC also have an abnormal temperature or white blood cell count, and be started on a new antimicrobial agent. The third tier definitions, possible and probable VAP, require that patients with IVAC also have laboratory and/or microbiological evidence of respiratory infection. CONCLUSIONS: Ventilator-associated events surveillance was implemented in January 2013 in the CDC's National Healthcare Safety Network. Modifications to improve surveillance may be made as additional data become available and users gain experience with the new definitions.

Findings of this study suggest the traditional sliding scale insulin (SSI) method does not improve target glucose values among adult medical inpatients. Timing of blood glucose (BC) measurement does affect the required SSI dose. BC measurement and insulin dose administration should be accomplished immediately prior to mealtime.

The accidental placement of feeding tubes into the airway is a rare but serious complication of blind feeding tube placement in pediatrics. A method using a colorimetric carbon dioxide detector has been tested as a means of decreasing the risk of inadvertent airway placement of gastric tubes in adults, but to date, a similar study has not been accomplished in pediatric patients. This study sought to evaluate the efficacy of a procedure using the colorimetric device during blind gastric tube placement in children. The results demonstrated that the study procedure using the device is effective in detecting inadvertent tube placement into the lung in the pediatric population.

As blood products are being used more judiciously, registered nurses need to develop practices to facilitate the effective administration of these products. The study results suggest both the syringe push method and the continuous infusion method of normal saline provide adequate line patency during packed red blood cell infusions through peripheral catheters.

This quantitative study was designed to identify the needs of family members of neuroscience patients. An adaptation of the Critical Care Family Needs Inventory was used to identify the top 10 needs of neuroscience families. Results were compared on the basis of whether the admission was planned or emergent. Needs were further examined on the basis of a family's perception of patient prognosis and communication with physicians and nurses. Most needs were recognized as being either important or very important with the need for information about the patient's care receiving the highest rating. Significant differences were noted between family members who expected their loved one to return to normal or with a slight decrease in activity versus those who expected their loved one to have a moderate to complete inability to perform normal activities. Communication with nurses was rated excellent or good significantly more often than communication with physicians.

BACKGROUND: An update of evidence-based guidelines concerning liberation from mechanical ventilation is needed as new evidence has become available. The American College of Chest Physicians (CHEST) and the American Thoracic Society (ATS) have collaborated to provide recommendations to clinicians concerning liberation from the ventilator. METHODS: Comprehensive evidence syntheses, including meta-analyses, were performed to summarize all available evidence relevant to the guideline panel's questions. The evidence was appraised using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach, and the results were summarized in evidence profiles. The evidence syntheses were discussed and recommendations developed and approved by a multidisciplinary committee of experts in mechanical ventilation. RESULTS: Recommendations for three population, intervention, comparator, outcome (PICO) questions concerning ventilator liberation are presented in this document. The guideline panel considered the balance of desirable (benefits) and undesirable (burdens, adverse effects, costs) consequences, quality of evidence, feasibility, and acceptability of various interventions with respect to the selected questions. Conditional (weak) recommendations were made to use inspiratory pressure augmentation in the initial spontaneous breathing trial (SBT) and to use protocols to minimize sedation for patients ventilated for more than 24 h. A strong recommendation was made to use preventive noninvasive ventilation (NIV) for high-risk patients ventilated for more than 24 h immediately after extubation to improve selected outcomes. The recommendations were limited by the quality of the available evidence. CONCLUSIONS: The guideline panel provided recommendations for inspiratory pressure augmentation during an initial SBT, protocols minimizing sedation, and preventative NIV, in relation to ventilator liberation.

BACKGROUND: In the medical intensive care unit at the University of Virginia Health System, capnography is used to detect end-tidal carbon dioxide to protect patients from inadvertent airway cannulation during placement of gastric tubes. OBJECTIVES: To compare the method in which capnography is used with a method in which a colorimetric carbon dioxide detector is used and to determine what variables affect accurate placement of gastric tubes. METHODS: A prospective convenience sample of 195 gastric tube insertions was studied in 130 adult patients in a medical intensive care unit. Standard insertions of gastric tubes (done with capnography) were simultaneously monitored by using a disposable colorimetric device, with a color change indicating the presence of carbon dioxide. RESULTS: Insertion variables included tube type (60% Salem sump tubes, 40% soft-bore feeding tubes), route of insertion (71% oral, 29% nasal), mechanical ventilation (81%), and decreased mental status (72%). Carbon dioxide was successfully detected with the colorimetric indicator (within seconds) in all insertions in which carbon dioxide was detected by capnography. When carbon dioxide was detected (27% of insertions), the tubes were withdrawn and reinserted. Carbon dioxide detection during tube placement was significantly associated with nasal insertions (P = .03) and spontaneously breathing/nonintubated status (P = .01) but not with mental status or tube type. CONCLUSIONS: A colorimetric device is as accurate as capnography for detecting carbon dioxide during placement of gastric tubes.

Clinicians commonly sedate critically ill patients. Sedatives should be administered to achieve predetermined end points. Most currently available scales used to assess sedation are inadequate because they focus on a single domain, such as consciousness. The development of the American Association of Critical-Care Nurses' Sedation Assessment Scale is described. This new scale consists of 5 domains: consciousness, agitation, anxiety, sleep, and patient-ventilator synchrony. A major advantage of the scale is that its domains parallel common goals of sedation therapy for critically ill patients. The proposed measurements for each domain are based on a comprehensive evaluation of the science and expert recommendations. Before the scale is widely used, clinical testing is required to determine its validity and reliability in a variety of critically ill patients and care situations.

PURPOSE: Extubation failure is associated with adverse outcomes in mechanically ventilated patients, and it is believed that high rates of failed planned extubation (FPE) should be avoided. However, many believe that very low rates may also correlate with adverse outcomes if resulting from overly conservative weaning practices. We examined the relationship between the percentage of FPE (%FPE) and associated outcomes, with the aim of elucidating a favorable middle range. METHODS: A total of 1395 extubations were analyzed in mechanically ventilated subjects. Monthly %FPE values were separated into tertiles. Ventilator-free days (VFDs), intensive care unit-free days (IFDs), and mortality were compared among tertiles. RESULTS: Monthly %FPE tertiles were as follows: low, less than 7%; intermediate, 7% to 15%; and high, greater than 15%. There were significant differences in VFDs and IFDs by tertile from low to high (VFDs: low, 11.8; intermediate, 12.1; high, 9.9 [P = .003]; IFDs: low, 10.5; intermediate, 10.7; high, 9.0 [P = .033]). Post hoc comparisons demonstrated significant differences between the middle and high tertiles for both VFDs and IFDs. CONCLUSIONS: Although exact rates may vary depending on setting, this suggests that a high %FPE (>15) should be avoided in the intensive care unit and that there may be an intermediate range where ventilator outcomes are optimized.

OBJECTIVE: To improve clinical and financial outcomes for neuroscience patients by using an "outcomes-managed" model of care delivery and 2 acute care nurse practitioners as outcomes managers. METHODS: Baseline data from the year before implementation of the care model were compared with data from the first 6 months of implementation. A random list of 122 adult patients admitted to the neuroscience intensive care unit or the acute care neurosurgery unit of a university teaching hospital between January and December 1998 was generated to provide the baseline data. The prospective sample included 402 patients admitted to either unit during the first 6 months of the project (January through June 1999). The acute care nurse practitioners used an evidence-based multidisciplinary plan of care to manage all patients. RESULTS: No differences were found in age, sex, or ethnicity between groups. Patients managed by acute care nurse practitioners had significantly shorter overall length of stay (P = .03), shorter mean length of stay in the intensive care unit (P < .001), lower rates of urinary tract infection and skin breakdown (P < .05), and shorter time to discontinuation of the Foley catheter and mobilization (P <.05). The outcomes-managed group was hospitalized 2306 fewer days than the baseline group, at a total cost savings of $2,467328. CONCLUSIONS: Clinical and financial outcomes are improved significantly by identifying patients at risk, monitoring for complications, and having acute care nurse practitioners manage the patients.
