Society of Critical Care Medicine Guidelines on Recognizing and Responding to Clinical Deterioration Outside the ICU: 2023.

RATIONALE: Clinical deterioration of patients hospitalized outside the ICU is a source of potentially reversible morbidity and mortality. To address this, some acute care hospitals have implemented systems aimed at detecting and responding to such patients. OBJECTIVES: To provide evidence-based recommendations for hospital clinicians and administrators to optimize recognition and response to clinical deterioration in non-ICU patients. PANEL DESIGN: The 25-member panel included representatives from medicine, nursing, respiratory therapy, pharmacy, patient/family partners, and clinician-methodologists with expertise in developing evidence-based Clinical Practice Guidelines. METHODS: We generated actionable questions using the Population, Intervention, Control, and Outcomes (PICO) format and performed a systematic review of the literature to identify and synthesize the best available evidence. We used the Grading of Recommendations Assessment, Development, and Evaluation Approach to determine certainty in the evidence and to formulate recommendations and good practice statements (GPSs). RESULTS: The panel issued 10 statements on recognizing and responding to non-ICU patients with critical illness. Healthcare personnel and institutions should ensure that all vital sign acquisition is timely and accurate (GPS). We make no recommendation on the use of continuous vital sign monitoring among unselected patients. We suggest focused education for bedside clinicians in signs of clinical deterioration, and we also suggest that patient/family/care partners' concerns be included in decisions to obtain additional opinions and help (both conditional recommendations). We recommend hospital-wide deployment of a rapid response team or medical emergency team (RRT/MET) with explicit activation criteria (strong recommendation). We make no recommendation about RRT/MET professional composition or inclusion of palliative care members on the responding team but suggest that the skill set of responders should include eliciting patients' goals of care (conditional recommendation). Finally, quality improvement processes should be part of a rapid response system. CONCLUSIONS: The panel provided guidance to inform clinicians and administrators on effective processes to improve the care of patients at-risk for developing critical illness outside the ICU.

We make no recommendation on the use of continuous vital sign monitoring among "unselected" patients due to the absence of data regarding the benefit and the potential harms of false positive alarms, the risk of alarm fatigue, and cost. We suggest focused education for bedside clinicians in signs of clinical deterioration, and we also suggest that patient/family/care partners' concerns be included in decisions to obtain additional opinions and help (both conditional recommendations).

Hidden Obligatory Fluid Intake in Critical Care Patients.

INTRODUCTION: In addition to the fluid intake in the form of intravenous maintenance or boluses in intensive care unit (ICU) patients, there are sources of fluids that may remain unrecognized but contribute significantly to the overall fluid balance. We hypothesized that fluids not ordered as boluses or maintenance infusions-"hidden obligatory fluids"-may contribute more than a liter to the fluid intake of a patient during any random 24 hours of critical care admission. METHODS: Patients admitted to the Harlem Hospital ICU for at least 24 hours were included in this study (N = 98). Medical records and nursing charts were reviewed to determine the sources and volumes of various fluids for the study patients. RESULTS: The mean hidden obligatory volume for an ICU patient was calculated to be 978 mL (standard deviation [SD]: 904, median: 645) and 1571 mL (SD: 1023, median: 1505), with enteral feeds compared to the discretionary volume of 2821 mL (SD: 2367, median: 2595); this obligatory fluid volume was affected by a patient's need for pressor support and renal replacement therapy. CONCLUSION: Hidden obligatory fluids constitute a major source of the fluid intake among patients in a critical care unit. Up to 1.5 L should be taken into account during daily decision making to effectively regulate their volumes.

Caring for Patients or Organs: New Therapies Raise New Dilemmas in the Emergency Department.

Two potentially lifesaving protocols, emergency preservation and resuscitation (EPR) and uncontrolled donation after circulatory determination of death (uDCDD), currently implemented in some U.S. emergency departments (EDs), have similar eligibility criteria and initial technical procedures, but critically different goals. Both follow unsuccessful cardiopulmonary resuscitation and induce hypothermia to "buy time": one in trauma patients suffering cardiac arrest, to enable surgical repair, and the other in patients who unexpectedly die in the ED, to enable organ donation. This article argues that to fulfill patient-focused fiduciary obligations and maintain community trust, institutions implementing both protocols should adopt and publicize policies to guide ED physicians to utilize either protocol for particular patients, in order to address the appearance of conflict of interest arising from the protocols' similarities. It concludes by analyzing ethical implications of incentives that may influence institutions to develop the expertise required for uDCDD but not EPR.

Experience With a New Process - Condition T - for Uncontrolled Donation After Circulatory Determination of Death in a University Emergency Department.

BACKGROUND: In the United States, organ donation after circulatory death (DCD) determination is increasing among those who are removed from life-sustaining therapy but is rare when death is unexpected. We created a program for uncontrolled DCD (uDCD). METHODS: A comprehensive program was created to train personnel to identify and respond quickly to potential donors after unexpected death. The process termed Condition T was implemented in the emergency department (ED) of 2 academic medical centers. All ED deaths were screened for uDCD potential. Eligible donors included patients with preexisting donor designation who received cardiopulmonary resuscitation, failed to respond, and were pronounced dead. RESULTS: Over 350 nurses, physicians, perfusionists, organ procurement personnel, and administrators were trained. From February 2009 to June 2010, a total of 18 patients were potential Condition T candidates. Six Condition T responses were triggered. Three donors underwent cannulation, and 4 organs were recovered (3 kidney and 1 liver) from 2 donors. Time from Condition T trigger to perfusion with organ preservation solution ranged from 14 to 22.3 minutes. Perfusion duration was 197 and 221 minutes. No recovered organs were transplanted because biopsies showed prolonged warm ischemia. CONCLUSIONS: It is feasible to create a process to rapidly intervene in the ED for uDCD. However, no organ transplants resulted. The utility and sustainability of an uDCD program in this particular setting are questionable.

Management of the Potential Organ Donor in the ICU: Society of Critical Care Medicine/American College of Chest Physicians/Association of Organ Procurement Organizations Consensus Statement.

This document was developed through the collaborative efforts of the Society of Critical Care Medicine, the American College of Chest Physicians, and the Association of Organ Procurement Organizations. Under the auspices of these societies, a multidisciplinary, multi-institutional task force was convened, incorporating expertise in critical care medicine, organ donor management, and transplantation. Members of the task force were divided into 13 subcommittees, each focused on one of the following general or organ-specific areas: death determination using neurologic criteria, donation after circulatory death determination, authorization process, general contraindications to donation, hemodynamic management, endocrine dysfunction and hormone replacement therapy, pediatric donor management, cardiac donation, lung donation, liver donation, kidney donation, small bowel donation, and pancreas donation. Subcommittees were charged with generating a series of management-related questions related to their topic. For each question, subcommittees provided a summary of relevant literature and specific recommendations. The specific recommendations were approved by all members of the task force and then assembled into a complete document. Because the available literature was overwhelmingly comprised of observational studies and case series, representing low-quality evidence, a decision was made that the document would assume the form of a consensus statement rather than a formally graded guideline. The goal of this document is to provide critical care practitioners with essential information and practical recommendations related to management of the potential organ donor, based on the available literature and expert consensus.

Multiple successful desensitizations to brentuximab vedotin: a case report and literature review.

Brentuximab vedotin is an antibody-drug conjugate FDA-approved for the treatment of systemic anaplastic large-cell lymphoma (ALCL) that has relapsed after multiagent chemotherapy. At least 2 cases of hypersensitivity reactions to brentuximab vedotin have been reported, without attempted desensitization. This report describes a morbidly obese 32-year-old woman with ALCL that relapsed after autologous stem cell transplantation, who was treated on a phase II clinical study with brentuximab vedotin. After 1 dose, she experienced near-complete remission, but therapy was stopped because of severe drug-related toxicity. She then received 5 cytotoxic treatments and radiation, and ultimately experienced disease progression. The patient was rechallenged with brentuximab vedotin approximately 28 months after initial exposure and tolerated the dose well, but experienced a significant allergic reaction with the next dose. High-dose steroid and antihistamine prophylaxis administered 50 minutes before the subsequent brentuximab vedotin infusion was unsuccessful in mitigating this reaction. Brentuximab vedotin was successfully infused according to a rapid desensitization protocol. With progressive dose titration and supportive care, the patient tolerated this therapy. She received 11 doses through a rapid desensitization protocol and experienced a durable disease remission.

Circulatory death determination in uncontrolled organ donors: a panel viewpoint.

One barrier for implementing programs of uncontrolled organ donation after the circulatory determination of death is the lack of consensus on the precise moment of death. Our panel was convened to study this question after we performed a similar analysis on the moment of death in controlled organ donation after the circulatory determination of death. We concluded that death could be determined by showing the permanent or irreversible cessation of circulation and respiration. Circulatory irreversibility may be presumed when optimal cardiopulmonary resuscitation efforts have failed to restore circulation and at least a 7-minute period has elapsed thereafter during which autoresuscitation to restored circulation could occur. We advise against the use of postmortem organ support technologies that reestablish circulation of warm oxygenated blood because of their risk of retroactively invalidating the required conditions on which death was declared.

Mpox Pain Management with Topical Agents: A Case Series.

With the recent spread in monkeypox cases, continuous efforts are made to manage the disease efficiently. Pain at the site of monkeypox lesions and in areas of skin breakdown can be severe. The origin of pain is likely neuropathic. The Centers for Disease Control and Prevention (CDC) has issued general guidelines to control pain with non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen, gabapentin, and topical agents such as corticosteroids and lidocaine. Guidelines circulated by the World Health Organization (WHO) suggest acetaminophen, tramadol, opioids, and/or topical lidocaine for symptomatic pain management. No first line agent with proven beneficial effect has been recommended in these patients. We present two patients' painful experiences with Monkeypox and suggest lessons learned.

Ethics guidelines for research with the recently dead.

The objective of the multidisciplinary expert Consensus Panel on Research with the Recently Dead (CPRRD) was to craft ethics guidelines for research with the recently dead. The CPRRD recommends that research with the recently dead: (i) receive scientific and ethical review and oversight; (ii) involve the community of potential research subjects; (iii) be coordinated with organ procurement organizations; (iv) not conflict with organ donation or required autopsy; (v) use procedures respectful of the dead; (vi) be restricted to one procedure per day; (vii) preferably be authorized by first-person consent, though both general advance research directives and surrogate consent are acceptable; (viii) protect confidentiality; (ix) not impose costs on subjects' estates or next of kin and not involve payment; (x) clearly explain ultimate disposition of the body.

Cardiorespiratory instability before and after implementing an integrated monitoring system.

OBJECTIVES: Cardiorespiratory instability may be undetected in monitored step-down unit patients. We explored whether using an integrated monitoring system that continuously amalgamates single noninvasive monitoring parameters (heart rate, respiratory rate, blood pressure, and peripheral oxygen saturation) into AN instability index value (INDEX) correlated with our single-parameter cardiorespiratory instability concern criteria, and whether nurse response to INDEX alert for patient attention was associated with instability reduction. DESIGN: Prospective, longitudinal evaluation in sequential 8-, 16-, and 8-wk phases (phase I, phase II, and phase III, respectively). SETTING: A 24-bed trauma step-down unit in single urban tertiary care center. PATIENTS: All monitored patients. INTERVENTIONS: Phase I: Patients received continuous single-channel monitoring (heart rate, respiratory rate, blood pressure, and peripheral oxygen saturation) and standard care; INDEX background was recorded but not displayed. Phase II: INDEX was background-recorded; staff was educated on use. Phase III: Staff used a clinical response algorithm for INDEX alerts. MEASUREMENT AND MAIN RESULTS: Any monitored parameters even transiently beyond local cardiorespiratory instability concern triggers (heart rate of <40 or >140 beats/min, respiratory rate of <8 or >36 breaths/min, systolic blood pressure of <80 or >200 mm Hg, diastolic blood pressure of >110 mm Hg, and peripheral oxygen saturation of <85%) defined INSTABILITYmin. INSTABILITYmin further judged as both persistent and serious defined INSTABILITYfull. The INDEX alert states were defined as INDEXmin and INDEXfull by using same classification. Phase I and phase III admissions (323 vs. 308) and monitoring (18,258 vs. 18,314 hrs) were similar. INDEXmin and INDEXfull correlated significantly with INSTABILITYmin and INSTABILITYfull (r = .713 and r = .815, respectively, p < .0001). INDEXmin occurred before INSTABILITYmin in 80% of cases (mean advance time 9.4 ± 9.2 mins). Phase I and phase III admissions were similarly likely to develop INSTABILITYmin (35% vs. 33%), but INSTABILITYmin duration/admission decreased from phase I to phase III (p = .018). Both INSTABILITYfull episodes/admission (p = .03) and INSTABILITYfull duration/admission (p = .05) decreased in phase III. CONCLUSION: The integrated monitoring system INDEX correlated significantly with cardiorespiratory instability concern criteria, usually occurred before overt instability, and when coupled with a nursing alert was associated with decreased cardiorespiratory instability concern criteria in step-down unit patients.

The circulatory-respiratory determination of death in organ donation.

OBJECTIVE: Death statutes permit physicians to declare death on the basis of irreversible cessation of circulatory-respiratory or brain functions. The growing practice of organ donation after circulatory determination of death now requires physicians to exercise greater specificity in circulatory-respiratory death determination. We studied circulatory-respiratory death determination to clarify its concept, practice, and application to innovative circulatory determination of death protocols. RESULTS: It is ethically and legally appropriate to procure organs when permanent cessation (will not return) of circulation and respiration has occurred but before irreversible cessation (cannot return) has occurred because permanent cessation: 1) is an established medical practice standard for determining death; 2) is the meaning of "irreversible" in the Uniform Determination of Death Act; and 3) does not violate the "Dead Donor Rule." CONCLUSIONS: The use of unmodified extracorporeal membrane oxygenation in the circulatory determination of death donor after death is declared should be abandoned because, by restoring brain circulation, it retroactively negates the previous death determination. Modifications of extracorporeal membrane oxygenation that avoid this problem by excluding brain circulation are contrived, invasive, and, if used, should require consent of surrogates. Heart donation in circulatory determination of death is acceptable if proper standards are followed to declare donor death after establishing the permanent cessation of circulation. Pending additional data on "auto-resuscitation," we recommend that all circulatory determination of death programs should utilize the prevailing standard of 2 to 5 mins of demonstrated mechanical asystole before declaring death.

Lithium and Chlorine-Rich Preparation of Mechanochemically Activated Antiperovskite Composites for Solid-State Batteries.

Assembling all-solid-state batteries presents a unique challenge due to chemical and electrochemical complexities of interfaces between a solid electrolyte and electrodes. While the interface stability is dictated by thermodynamics, making use of passivation materials often delays interfacial degradation and extends the cycle life of all-solid cells. In this work, we investigated antiperovskite lithium oxychloride, Li3OCl, as a promising passivation material that can engineer the properties of solid electrolyte-Li metal interfaces. Our experiment to obtain stoichiometric Li3OCl focuses on how the starting ratios of lithium and chlorine and mechanochemical activation affect the phase stability. For substantial LiCl excess conditions, the antiperovskite phase was found to form by simple melt-quenching and subsequent high-energy ball-milling. Li3OCl prepared with 100% excess LiCl exhibits ionic conductivity of 3.2 × 10-5 S cm-1 at room temperature, as well as cathodic stability against Li metal upon the extended number of cycling. With a conductivity comparable to other passivation layers, and stable interface properties, our Li3OCl/LiCl composite has the potential to stably passivate the solid-solid interfaces in all-solid-state batteries.

Effectiveness of the Medical Emergency Team: the importance of dose.

Up to 17% of hospital admissions are complicated by serious adverse events unrelated to the patients presenting medical condition. Rapid Response Teams (RRTs) review patients during early phase of deterioration to reduce patient morbidity and mortality. However, reports of the efficacy of these teams are varied. The aims of this article were to explore the concept of RRT dose, to assess whether RRT dose improves patient outcomes, and to assess whether there is evidence that inclusion of a physician in the team impacts on the effectiveness of the team. A review of available literature suggested that the method of reporting RRT utilization rate, (RRT dose) is calls per 1,000 admissions. Hospitals with mature RRTs that report improved patient outcome following RRT introduction have a RRT dose between 25.8 and 56.4 calls per 1,000 admissions. Four studies report an association between increasing RRT dose and reduced in-hospital cardiac arrest rates. Another reported that increasing RRT dose reduced in-hospital mortality for surgical but not medical patients. The MERIT study investigators reported a negative relationship between MET-like activity and the incidence of serious adverse events. Fourteen studies reported improved patient outcome in association with the introduction of a RRT, and 13/14 involved a Physician-led MET. These findings suggest that if the RRT is the major method for reviewing serious adverse events, the dose of RRT activation must be sufficient for the frequency and severity of the problem it is intended to treat. If the RRT dose is too low then it is unlikely to improve patient outcomes. Increasing RRT dose appears to be associated with reduction in cardiac arrests. The majority of studies reporting improved patient outcome in association with the introduction of an RRT involve a MET, suggesting that inclusion of a physician in the team is an important determinant of its effectiveness.
