RESUMO
Unplanned extubations (UE) frequently occur in critical care units. These events are precipitated by many risk factors and are associated with adverse outcomes for patients. We reviewed the current literature to examine factors related to UE and presented the analysis of 41 articles critical to the topic. Our review has identified specific risk factors that we discuss in this review, such as sedation strategies, physical restraints, endotracheal tube position, and specific nursing care aspects associated with an increased incidence of UE. We recommend interventions to reduce the risk of UE. However, we recommend that bundled rather than a single intervention is likely to yield higher success, given the heterogeneity of factors contributing to increasing the risk of UE.
RESUMO
The surge in clinical demand, shortage in personal protective equipment and high-exposure risk for healthcare workers during the COVID-19 pandemic has challenged hospital common practices and forced a reassessment of care delivery models. Code blue teams are highly specialised units that partake in life-saving situations that can jeopardise the safety of team members. There is a paucity of guidance in regards to proper infection control measures to protect the responders.This study describes a methodical approach to assessing vulnerabilities to transmission of SARS-CoV-2 within existing code blue practices, modalities to limit the number of code blue team responders and modifications to the protocol at a large community teaching hospital. The effort undertaken faced challenges due to the nature of the pandemic and the increased demand on healthcare workers. Quality improvement methods facilitated our protocol design and implementation. To this date, there has been no identified COVID-19 disease in any protected code blue (PCB) team members. We recommend that similar practices be considered and adopted widely and practised periodically.

BACKGROUND: Various intensivist staffing models have been suggested, but the long-term sustainability and outcomes vary and may not be sustained. We examined the impact of implementing a high-intensity intensivist coverage model with a nighttime in-house nocturnist (non-intensivist) and its effect on intensive care unit (ICU) outcomes. METHODS: We obtained historical control baseline data from 2007 to 2011 and compared the same data from 2011 to 2015. The Acute Physiological and Chronic Health Evaluation outcomes system was utilized to collect clinical, physiological, and outcome data on all adult patients in the medical ICU and to provide severity-adjusted outcome predictions. The model consists of a mandatory in-house daytime intensivist service that leads multidisciplinary rounds, and an in-house nighttime coverage is provided by nocturnist (nonintensivists) with current procedural skills in airways management, vascular access, and commitment to supervise house staff as needed. The intensivist continues to be available remotely at nighttime for house staff and consultation with the nocturnist. A backup intensivist is available for surge management. RESULTS: First year yielded improved throughput (2428 patients/year to 2627 then 2724 at fifth year). Case mix stable at 53.7 versus 55.2. The ICU length of stay decreased from 4.7 days (predicted 4.25 days) to 3.8 days (4.15) in first year; second year: 3.63 days (4.29 days); third year: 3.24 days (4.37), fourth year: 3.34 days (4.45), and fifth year: 3.61 days (4.42). Intensive care unit <24 hours readmission remained at 1%; >24 hours increased from 4% to 6%. Low-risk monitoring admissions remained at an average 17% (benchmark 17.18%). Intensive care unit mortality improved with standardized mortality ration averaging at 0.84. Resident satisfaction surveys improved. CONCLUSIONS: Implementing an intensivist service with nighttime nocturnist staffing in a high-intensity large teaching hospital is feasible and improved ICU outcomes in a sustained manner that persisted after the initial implementation phase. The model resulted in reduced and sustained observed-to-predicted length of ICU stay.

BACKGROUND: Although numerous studies have shown that anticoagulation of nonvalvular atrial fibrillation (AF) significantly decreases the risk of stroke, anticoagulating critically ill patients in the intensive care unit (ICU) poses many challenges and the benefits have not been determined. OBJECTIVE: To assess the safety and efficacy of anticoagulation in AF patients with sepsis. Ascertaining the incidence of complications associated with anticoagulation therapy, such as bleeding, can optimize patient care. METHODS: This was a retrospective observational study to assess the incidence of stroke and anticoagulation-related complications (eg, bleeding, heparin-induced thrombocytopenia) in AF patients with severe sepsis. This study was undertaken in a surgical/medical ICU of a teaching, community-based hospital. A total of 115 patients with AF who were admitted with a diagnosis of sepsis were included in the study. RESULTS: Among 115 patients (mean age 81 ± 9.5 years and CHADS2 [congestive heart failure, hypertension, age >75 years, diabetes mellitus, stroke] score 3.17 ± 1.20), 80 (69.6%) did not receive anticoagulation treatment during their hospitalization and none of these patients developed a stroke. Anticoagulation-related complications occurred more often in the group who received anticoagulation (8.6% [3/35] vs 0%, P = .008). In the anticoagulated group, a majority of the patients were within therapeutic range less than 50% of the time during their ICU stay. There was no statistically significant difference in survival rates during their hospitalization (66.2% [53/80] for the non-anticoagulated group vs 74.3% [26/35] in the anticoagulated group, P = .392). CONCLUSION: Administration of anticoagulation for elderly patients with a CHADS2 score at 2 or more in the setting of sepsis can be associated with an increased risk of anticoagulation-related complications (eg, bleeding, heparin-induced thrombocytopenia). Managing and targeting a therapeutic goal with warfarin therapy in critically ill patients with sepsis is challenging. Further studies are necessary to provide appropriate recommendations in this setting.

BACKGROUND: Unplanned extubation represents a threat to patient safety, and risk factors and prevention strategies for unplanned extubation have not been fully explored. OBJECTIVES: To define high-risk patients for unplanned extubation and determine clinicians' beliefs on perceived risks for unplanned extubation METHODS: With a Web-based survey instrument we surveyed critical care clinician members of the American Association for Respiratory Care, the American Association of Critical Care Nurses, and the Society of Critical Care Medicine. RESULTS: Surveys were completed by 1,976 clinicians, including 419 respiratory therapists, 870 critical care nurses, and 605 critical care physicians. The majority of respondents considered an outward migration of the endotracheal tube (by 3 cm, 2 cm if an air leak is present) to represent a risk for unplanned extubation. Respondents considered the following as high risk for unplanned extubation: absence of physical restraints (72% of respondents), a nurse/patient ratio of 1/3 (60%), trips out of the intensive care unit (59%), light sedation (43%), and bedside portable radiograph (29%). In addition, most respondents considered accidental removal of the nasogastric tube (71%) or tugging on the endotracheal tube (87%) by the patient to be risk factors for unplanned extubation. The rank order of the perceived risks was related to the respondents' primary discipline. CONCLUSIONS: We identified perceived risk factors and defined "near misses" for unplanned extubation. Our findings should inform strategies for prevention of unplanned extubation.

BACKGROUND: Although use of sedation protocols and daily sedation interruption (DSI) improve outcome, their current use and barriers affecting their use are unclear. METHODS: We designed a multidisciplinary, Web-based survey to determine current use of sedation protocols and DSI and the perceived barriers to each, and administered it to members of the Society of Critical Care Medicine. RESULTS: The 904 responders were physicians (60%), nurses (14%), or pharmacists (12%); 45% worked in a university hospital. Of 64% having a sedation protocol, 78% used it for >or=50% of ventilated patients. Reasons for lack of protocol use included no physician order (35%), lack of nursing support (11%), and a fear of oversedation (7%). Daily sedation interruption was used by only 40%. Barriers to DSI included lack of nursing acceptance (22%), concern about risk of patient-initiated device removal (19%), and inducement of either respiratory compromise (26%) or patient discomfort (13%). Clinicians who prefer propofol were more likely to use DSI than those who prefer benzodiazepines (55% vs 40, P < .0001). CONCLUSIONS: Current intensive care unit sedation practices are heterogeneous, and the barriers preventing the use of both sedation protocols and DSI are numerous. These barriers should be addressed on an institutional basis to boost the use of these evidence-based practices.

OBJECTIVE: Weaning predictors are often incorporated in protocols to predict weaning outcome for patients on mechanical ventilation. The predictors are used as a decision point in protocols to determine whether a patient may advance to a spontaneous breathing trial. The impact of including predictors in a weaning protocol has not been previously studied. We designed a study to determine the effect of including a weaning predictor (frequency-tidal volume ratio, or f/Vt) in a weaning protocol. DESIGN: Randomized, blinded controlled trial. SETTING: Academic teaching hospitals. PATIENTS: Three hundred and four patients admitted to intensive care units at three academic teaching hospitals. INTERVENTIONS: Patients were screened daily for measures of oxygenation, cough and secretions, adequate mental status, and hemodynamic stability. Patients were randomized to two groups; in one group the f/Vt was measured but not used in the decision to wean (n = 151), but in the other group, f/Vt was measured and used, using a threshold of 105 breaths/min/L (n = 153). Patients passing the screen received a 2-hr spontaneous breathing trial. Patients passing the spontaneous breathing trial were eligible for an extubation attempt. MEASUREMENTS AND MAIN RESULTS: Groups were similar with regard to gender, age, and Acute Physiology and Chronic Health Evaluation II score. The median duration for weaning time was significantly shorter in the group where the weaning predictor was not used (2.0 vs. 3.0 days, p = .04). There was no difference with regard to the extubation failure, in-hospital mortality rate, tracheostomy, or unplanned extubation. CONCLUSIONS: Including a weaning predictor (f/Vt) in a protocol prolonged weaning time. In addition, the predictor did not confer survival benefit or reduce the incidence of extubation failure or tracheostomy. The results of this study indicate that f/Vt should not be used routinely in weaning decision making.

STUDY OBJECTIVES: To characterize the frequency, severity, risk factors, and clinician response to propofol-associated hypertriglyceridemia and hypertriglyceridemia-associated pancreatitis. DESIGN: Retrospective analysis. SETTING: Medical and surgical intensive care units. PATIENTS: One hundred fifty-nine adult intensive care patients administered propofol for 24 hours or longer and who had at least one serum triglyceride concentration. MEASUREMENTS AND MAIN RESULTS: Patient records were reviewed to identify the frequency of hypertriglyceridemia (serum triglyceride concentration > or = 400 mg/dl) and pancreatitis (amylase concentration > or = 125 IU/L, lipase concentration > or = 60 IU/L, and abdominal computed tomography scan or clinical examination findings consistent with pancreatitis). Of the 159 patients, 29 (18%) developed hypertriglyceridemia; six (21%) of the 29 had a serum triglyceride concentration of 1000 mg/dl or greater. The median maximum serum triglyceride concentration was 696 mg/dl (range 403-1737 mg/dl). At the time when hypertriglyceridemia was detected, the median infusion rate of propofol was 50 microg/kg/minute (range 5-110 microg/kg/min). The median time from the start of propofol therapy to identification of hypertriglyceridemia was 54 hours (range 14-319 hrs). Propofol was discontinued within 24 hours of detecting the hypertriglyceridemia 84% of the time. Compared with those who did not develop hypertriglyceridemia, patients who developed hypertriglyceridemia were older, had a longer intensive care unit stay, and received propofol for a longer duration; they were also more likely to be admitted to the medical versus the surgical intensive care unit. Pancreatitis developed in three (10%) of the 29 patients with hypertriglyceridemia. CONCLUSION: Hypertriglyceridemia and hypertriglyceridemia-associated pancreatitis are often seen in intensive care patients receiving propofol. Serum triglyceride concentrations should be routinely monitored in these patients. In addition, alternative sedation strategies should be considered when hypertriglyceridemia is detected.

OBJECTIVE: To determine whether diagnosis and bedside observations predict outcomes of patients who have declined intubation but accept noninvasive positive pressure ventilation (NPPV) to treat their respiratory failure. DESIGN: Prospective multiple-center cohort trial. SETTING: Two teaching hospitals and two community-based hospitals in southeastern New England from January through October 1999. PATIENTS: All patients receiving NPPV for acute respiratory failure were screened and enrolled if they had a written do-not-intubate (DNI) order. INTERVENTIONS: Patients were begun on NPPV with mean inspiratory and expiratory pressures of 13.4 +/- 0.3 and 5.0 +/- 1 cm H2O, respectively. Respiratory therapists recorded demographic information, blood gases, and ventilator type and settings, and they made bedside assessments of cough strength, presence of airway secretions, awake state, and agitation. Patients were followed until discharge for duration of NPPV, survival status, and disposition. MEASUREMENTS AND MAIN RESULTS: Of 1,211 screened patients, 114 had a DNI status and were enrolled into the study. Of these, 49 (43%) survived to discharge. Age, gender, location in a community vs. teaching hospital, and initial pH and PaO2 did not affect survival, but a higher baseline PaCO2 was associated with a favorable odds ratios for survival to discharge. Diagnosis was an important determinant of survival, with congestive heart failure patients having significantly better survival rates than those with chronic obstructive pulmonary disease, cancer, pneumonia, or other diagnoses. A stronger cough and being awake were also associated with increased probability of survival. CONCLUSION: Patients with respiratory failure and a DNI status have a high overall mortality rate when treated with NPPV, but those with diagnoses such as congestive heart failure or chronic obstructive pulmonary disease, who have a strong cough, or who are awake have better prognoses. These data should be useful when counseling DNI patients and their families on use of NPPV.

We report a case of colchicine-induced myopathy, in which the initial presenting and predominant clinical feature was respiratory muscle dysfunction; there was also chronic renal failure and electromyographically-measured myopathy. Discontinuation of colchicine led to marked improvement. Colchicine discontinuation was the only therapy performed (other medications were unchanged), and within 3 weeks the patient had regained motor function and resumed daily activities. Myopathy from primary biliary cirrhosis was ruled out. In contrast to acute colchicine intoxication, chronic colchicine toxicity is related to prolonged use rather than colchicine serum level, so colchicine serum level was not measured and did not affect the decision to discontinue colchicine. Although the diagnosis was not confirmed by muscle biopsy, we believe the typical presentation and the rapid improvement after withdrawing colchicine confirm the diagnosis. We conclude that long-term colchicine therapy, especially in the setting of chronic renal failure, can produce symptomatic respiratory muscle weakness.

Hypersensitivity pneumonitis (HP) is a complex syndrome of varying intensity and clinical presentation, and has been described in association with numerous exposures. Early diagnosis is essential to limit irreversible lung damage. We describe a case of HP in a 42-year-old dry cleaner following occupational exposure to tetrachloroethylene (TCE). The diagnosis was suspected based on clinical presentation and radiographic studies, and confirmed by lung biopsy. A review of the literature reveals that HP has not been reported previously as an occupational lung disease in dry cleaners. We conclude that HP should be suspected in dry cleaners presenting with pulmonary complaints, and TCE should be considered as a potential trigger of disease. The spectrum of TCE-related occupational diseases and the diagnosis of HP are reviewed.
