BACKGROUND AND OBJECTIVESHigh‐flow nasal cannula (HFNC) oxygen may provide tailored benefits in patients with preset treatment limitations. The objective of this study was to assess the effectiveness of HFNC oxygen in patients with do‐not‐intubate (DNI) and/or do‐not‐resuscitate (DNR) orders.METHODSWe conducted a systematic review of interventional and observational studies. A search was performed using MEDLINE, EMBASE, CINAHL, Scopus, and Web of Science, from inception to October 15, 2018.RESULTSWe included six studies evaluating 293 patients. All studies had a high risk of bias. The hospital mortality rates of patients with DNI and/or DNR orders receiving HFNC oxygen were variable and ranged from 40% to 87%. In two before and after studies, the initiation of HFNC oxygen was associated with improved oxygenation and reduced respiratory rates. One comparative study found no difference in dyspnea reduction or morphine doses between patients using HFNC oxygen versus conventional oxygen. No studies evaluated quality of life in survivors or quality of death in nonsurvivors. HFNC was generally well tolerated with few adverse events identified.CONCLUSIONSWhile HFNC oxygen remains a viable treatment option for hospitalized patients who have acute respiratory failure and a DNI and/or DNR order, there is a paucity of high‐quality, comparative, effectiveness data to guide the usage of HFNC oxygen compared with other treatments, such as noninvasive ventilation, conventional oxygen, and palliative opioids.

80 Background: Several previous systematic reviews and meta-analyses have attempted to summarize toxicity of Immune Checkpoint inhibitors (ICIs). However, very soon after each one of these reviews has been published, it became outdated. ICIs are currently used in 14 different cancers and data is rapidly evolving from new clinical trials. A living Systematic review, which is defined as a systematic review that is continually updated to incorporate relevant new evidence as it becomes available, is necessary in this situations. Methods: In order to dynamically display content -- including textual data, tables, charts, and graphs – standard data formats and protocols were designed for various components of the systematic reviews carried out by researchers. Given these standardized formats, software was written to interpret this data and output the information in the appropriate format, such as a forest plot or data table. Finally, a dynamic interface that enables user inputs (such as which aspect of the meta-analysis to view) and displays the associated output was designed. The overall living Systematic Review infrastructure includes monthly literature searches, cumulative meta-analysis, and an online reporting platform. Results: We have developed a Living Systematic Review engine that can take in standardized data and reflect this data in an interactive, intuitive manner in the form of text, tables, and plots. This interface can also be manipulated via user input to organize and sort data tables or omit/highlight specific pieces of data. Conclusions: We have initiated the first living systematic review in immune-oncology that will be continuously updated, incorporating relevant new evidence as it becomes available, and will provide accurate and up to date toxicity estimates to support clinical decision making. The Living Systematic Review interface allows users to easily and intuitively access the most recent available clinical evidence on toxicity of ICIs.

Abstract Rationale No previous studies have examined the role of prehospital vulnerability in acute respiratory distress syndrome (ARDS) development and mortality in an acutely ill adult population. Objectives To describe the association between prehospital vulnerability and 1) the development of ARDS, 2) 28-day mortality, and 3) 1-year mortality. Methods This was a longitudinal prospective cohort study nested within the multicenter LIPS-A (Lung Injury Prevention Study-Aspirin) trial. We analyzed 301 participants who completed Vulnerable Elders Survey (VES) at baseline. Multivariable logistic regression and Cox regression analyses were used to describe the association between vulnerability and short-term outcomes (ARDS and 28-day mortality) and long-term outcomes (1-year mortality), respectively. Results The VES score ranged from 0 to 10 (median [interquartile range], 2.0 [0–6]); 143 (47.5%) fit criteria for prehospital vulnerability (VES ≥ 3). Vulnerability was not significantly associated with ARDS development (10 [7.0%] vulnerable patients developed ARDS as per LIPS-A study criteria vs. 20 [12.7%] without vulnerability; P = 0.10; adjusted odds ratio [95% confidence interval (CI)], 0.54 [0.24–1.24]; P = 0.15). Nor was vulnerability associated with 28-day mortality (15 [10.5%] vulnerable patients were dead by Day 28 vs. 11 [7.0%] nonvulnerable patients; P = 0.28; adjusted odds ratio [95% CI], 0.95 [0.39–2.26]; P = 0.90). Vulnerability was significantly associated with 1-year mortality in hospital survivors (35 [26.9%] vs. 13 [9.3%]; adjusted hazard ratio [95% CI], 2.20 [1.10–4.37]; P = 0.02). Conclusions In a population of adults recruited for their high risk of ARDS, prehospital vulnerability, measured by VES, was highly prevalent and strongly associated with 1-year mortality.

Objectives: Research indicates that the increasing population of over 25 million people in the United States who have limited English proficiency experience differences in decision-making and subsequent care at end of life in the ICU when compared with the general population. The objective of this study was to assess the perceptions of healthcare team members about the factors that influence discussions and decision-making about end of life for patients and family members with limited English proficiency in the ICU. Design: Qualitative study using semistructured interviews with ICU physicians, nurses, and interpreters. Setting: Three ICUs at Mayo Clinic Rochester. Subjects: Sixteen ICU physicians, 12 ICU nurses, and 12 interpreters. Intervention: None. Measurements and Main Results: We conducted 40 semistructured interviews. We identified six key differences in end-of-life decision-making for patients with limited English proficiency compared with patients without limited English proficiency: 1) clinician communication is modified and less frequent; 2) clinician ability to assess patient and family understanding is impaired; 3) relationship building is impaired; 4) patient and family understanding of decision-making concepts (e.g., palliative care) is impaired; 5) treatment limitations are often perceived to be unacceptable due to faith-based and cultural beliefs; and 6) patient and family decision-making styles are different. Facilitators of high-quality decision-making in patients with limited English proficiency included: 1) premeeting between clinician and interpreter; 2) interpretation that communicates empathy and caring; 3) bidirectional communication of cultural perspectives; 4) interpretation that improves messaging including appropriate word choice; and 5) clinician cultural humility. Conclusions: End-of-life decision-making is significantly different for ICU patients with limited English proficiency. Participants identified several barriers and facilitators to high-quality end-of-life decision-making for ICU patients and families with limited English proficiency. Awareness of these factors can facilitate interventions to improve high-quality, compassionate, and culturally sensitive decision-making for patients and families with limited English proficiency.

For best outcomes, clinicians in the ICU need to attend not only to the immediate clinical needs of the critically ill patient, but also to higher human needs including psychologic, social, and spiritual. Understanding your patient as another human being with her or his fears, desires, preferences, and accomplishments is obviously important in order to provide compassionate care and achieve goal concordant outcomes. In an ever-evolving technological ICU environment, this may not be an easy task. All too often, we focus on monitors, devices, electronic records, and ignore the human being. Patients labeled with a disability are particularly vulnerable. Recently, I had the privilege to participate in the care of a Mayo Clinic patient with a history of cerebral palsy. In the midst of a life-threatening emergency, by paying attention to the human touch, the ICU team learned the story of a truly remarkable person. The essay below summarizes the patient’s and physician’s perspectives.
