Clinical Characteristics and Cause of Death Among Hospitalized Decedents With Cancer and COVID-19.

There is scant information on the clinical progression, end-of-life decisions, and cause of death of patients with cancer diagnosed with COVID-19. Therefore, we conducted a case series of patients admitted to a comprehensive cancer center who did not survive their hospitalization. To determine the cause of death, 3 board-certified intensivists reviewed the electronic medical records. Concordance regarding cause of death was calculated. Discrepancies were resolved through a joint case-by-case review and discussion among the 3 reviewers. During the study period, 551 patients with cancer and COVID-19 were admitted to a dedicated specialty unit; among them, 61 (11.6%) were nonsurvivors. Among nonsurvivors, 31 (51%) patients had hematologic cancers, and 29 (48%) had undergone cancer-directed chemotherapy within 3 months before admission. The median time to death was 15 days (95% confidence interval [CI], 11.8 to 18.2). There were no differences in time to death by cancer category or cancer treatment intent. The majority of decedents (84%) had full code status at admission; however, 53 (87%) had do-not-resuscitate orders at the time of death. Most deaths were deemed to be COVID-19 related (88.5%). The concordance between the reviewers for the cause of death was 78.7%. In contrast to the belief that COVID-19 decedents die because of their comorbidities, in our study only 1 of every 10 patients died of cancer-related causes. Full-scale interventions were offered to all patients irrespective of oncologic treatment intent. However, most decedents in this population preferred care with nonresuscitative measures rather than full support at the end of life.

Impact of an Interdisciplinary Goals-of-Care Program Among Medical Inpatients at a Comprehensive Cancer Center During the COVID-19 Pandemic: A Propensity Score Analysis.

PURPOSE: Many hospitals have established goals-of-care programs in response to the coronavirus disease 2019 pandemic; however, few have reported their outcomes. We examined the impact of a multicomponent interdisciplinary goals-of-care program on intensive care unit (ICU) mortality and hospital outcomes for medical inpatients with cancer. METHODS: This single-center study with a quasi-experimental design included consecutive adult patients with cancer admitted to medical units at the MD Anderson Cancer Center, TX, during the 8-month preimplementation (May 1, 2019-December 31, 2019) and postimplementation period (May 1, 2020-December 31, 2020). The primary outcome was ICU mortality. Secondary outcomes included ICU length of stay, hospital mortality, and proportion/timing of care plan documentation. Propensity score weighting was used to adjust for differences in potential covariates, including age, sex, cancer diagnosis, race/ethnicity, and Sequential Organ Failure Assessment score. RESULTS: This study involved 12,941 hospitalized patients with cancer (pre n = 6,977; post n = 5,964) including 1,365 ICU admissions (pre n = 727; post n = 638). After multicomponent goals-of-care program initiation, we observed a significant reduction in ICU mortality (28.2% v 21.9%; change -6.3%, 95% CI, -9.6 to -3.1; P = .0001). We also observed significant decreases in length of ICU stay (mean change -1.4 days, 95% CI, -2.0 to -0.7; P < .0001) and in-hospital mortality (7% v 6.1%, mean change -0.9%, 95% CI, -1.5 to -0.3; P = .004). The proportion of hospitalized patients with an in-hospital do-not-resuscitate order increased significantly from 14.7% to 19.6% after implementation (odds ratio, 1.4; 95% CI, 1.3 to 1.5; P < .0001), and do-not-resuscitate order was established earlier (mean difference -3.0 days, 95% CI, -3.9 to -2.1; P < .0001). CONCLUSION: This study showed improvement in hospital outcomes and care plan documentation after implementation of a system-wide, multicomponent goals-of-care intervention.

Outcomes and Predictors of 28-Day Mortality in Patients With Solid Tumors and Septic Shock Defined by Third International Consensus Definitions for Sepsis and Septic Shock Criteria.

BACKGROUND: Data assessing outcomes of patients with solid tumors demonstrating septic shock using the Third International Consensus Definitions for Sepsis and Septic Shock are scarce. RESEARCH QUESTION: What are the independent predictors of 28-day mortality in critically ill adults with solid tumors and septic shock? STUDY DESIGN AND METHODS: Cohort of solid tumor patients admitted to the ICU with septic shock. Demographic and clinical characteristics were gathered from the electronic health records. We developed a reduced multivariate logistics regression model to identify independent predictors of 28-day mortality and used Kaplan-Meier plots to assess survival. RESULTS: A total of 271 patients were included. The median age was 62 years (range, 19-94 years); 57.2% were men and 53.5% were White. The most common underlying malignancies were lung (19.2%), breast (7.7%), pancreatic (7.7%), and colorectal (7.4%) cancers. Most patients (84.5%) harbored metastatic disease. Twenty-eight days after ICU admission, 188 patients (69.4%) had died. Nonsurvivors showed a higher rate of advanced cancer, longer hospital stays before ICU admission, and higher Sequential Organ Failure Assessment scores at admission and throughout the ICU stay (P < .001 for all). The multivariate analysis identified metastatic disease (OR, 3.17; 95% CI, 1.43-7.03), respiratory failure (OR, 2.34; 95% CI, 1.15-4.74), elevated lactate levels (OR, 3.19; 95% CI, 1.90-5.36), and Eastern Cooperative Oncology Group performance scores of 3 or 4 (OR, 2.72; 95% CI, 1.33-5.57) as independent predictors of 28-day mortality. Only 38 patients (14%) were discharged home without medical assistance. INTERPRETATION: The 28-day mortality rate of patients with solid tumors and septic shock was considerably high. Factors associated with worse survival included advanced oncologic disease, poor performance status, high lactate level, and concomitant acute respiratory failure. Early goals-of-care discussions should be considered for frail patients with septic shock and advanced metastatic disease without denying access to the appropriate level of care.

Outcomes and Predictors of 28-Day Mortality in Patients With Hematologic Malignancies and Septic Shock Defined by Sepsis-3 Criteria.

BACKGROUND: To describe short-term outcomes and independent predictors of 28-dayx mortality in adult patients with hematologic malignancies and septic shock defined by the new Third International Consensus Definitions (Sepsis-3) criteria. METHODS: We performed a retrospective cohort study of patients admitted to the medical ICU with septic shock from April 2016 to March 2019. Demographic and clinical features and short-term outcomes were collected. We used descriptive statistics to summarize patient characteristics, logistic regression to identify predictors of 28-day mortality, and Kaplan-Meier plots to assess survival. RESULTS: Among the 459 hematologic patients with septic shock admitted to the ICU, 109 (23.7%) had received hematopoietic stem cell transplant. The median age was 63 years (range, 18-89 years), and 179 (39%) were women. Nonsurvivors had a higher Charlson comorbidity index (P=.007), longer length of stay before ICU admission (P=.01), and greater illness severity at diagnosis and throughout the hospital course (P<.001). The mortality rate at 28 days was 67.8% and increased with increasing sequential organ failure assessment score on admission (odds ratio [OR], 1.11; 95% CI, 1.03-1.20), respiratory failure (OR, 3.12; 95% CI, 1.49-6.51), and maximum lactate level (OR, 1.16; 95% CI, 1.10-1.22). Aminoglycosides administration (OR, 0.42; 95% CI, 0.26-0.69), serum albumin (OR, 0.51; 95% CI, 0.31-0.86), and granulocyte colony-stimulating factor (G-CSF) (OR, 0.40; 95% CI, 0.24-0.65) were associated with lower 28-day mortality. Life support limitations were present in 81.6% of patients at death. At 90 days, 19.4% of the patients were alive. CONCLUSIONS: Despite efforts to enhance survival, septic shock in patients with hematologic malignancies is still associated with high mortality rates and poor 90-day survival. These results demonstrate the need for an urgent call to action with higher awareness, including the further evaluation of interventions such as earlier ICU admission, aminoglycosides administration, and G-CSF treatment.

Survival in Immunocompromised Patients Ultimately Requiring Invasive Mechanical Ventilation: A Pooled Individual Patient Data Analysis.

Rationale: Acute respiratory failure (ARF) is associated with high mortality in immunocompromised patients, particularly when invasive mechanical ventilation is needed. Therefore, noninvasive oxygenation/ventilation strategies have been developed to avoid intubation, with uncertain impact on mortality, especially when intubation is delayed. Objectives: We sought to report trends of survival over time in immunocompromised patients receiving invasive mechanical ventilation. The impact of delayed intubation after failure of noninvasive strategies was also assessed. Methods: Systematic review and meta-analysis using individual patient data of studies that focused on immunocompromised adult patients with ARF requiring invasive mechanical ventilation. Studies published in English were identified through PubMed, Web of Science, and Cochrane Central (2008-2018). Individual patient data were requested from corresponding authors for all identified studies. We used mixed-effect models to estimate the effect of delayed intubation on hospital mortality and described mortality rates over time. Measurements and Main Results: A total of 11,087 patients were included (24 studies, three controlled trials, and 21 cohorts), of whom 7,736 (74%) were intubated within 24 hours of ICU admission (early intubation). The crude mortality rate was 53.2%. Adjusted survivals improved over time (from 1995 to 2017, odds ratio [OR] for hospital mortality per year, 0.96 [0.95-0.97]). For each elapsed day between ICU admission and intubation, mortality was higher (OR, 1.38 [1.26-1.52]; P < 0.001). Early intubation was significantly associated with lower mortality (OR, 0.83 [0.72-0.96]), regardless of initial oxygenation strategy. These results persisted after propensity score analysis (matched OR associated with delayed intubation, 1.56 [1.44-1.70]). Conclusions: In immunocompromised intubated patients, survival has improved over time. Time between ICU admission and intubation is a strong predictor of mortality, suggesting a detrimental effect of late initial oxygenation failure.

Variability in triage practices for critically ill cancer patients: A randomized controlled trial.

PURPOSE: Intensive care triage practices and end-user interpretation of triage guidelines have rarely been assessed. We evaluated agreement between providers on the prioritization of patients for ICU admission using different triage guidelines. MATERIALS AND METHODS: A multi-centered randomized study on providers from 18 different countries was conducted using clinical vignettes of oncological patients. The level of agreement between providers was measured using two different guidelines, with one being cancer specific. RESULTS: Amongst 257 providers, 52.5% randomly received the Society of Critical Care Prioritization Model, and 47.5% received a cancer specific flowchart as a guide. In the Prioritization Model arm the average entropy was 1.193, versus 1.153 in the flowchart arm (P = .095) indicating similarly poor agreement. The Fleiss' kappa coefficients were estimated to be 0.2136 for the SCCMPM arm and 0.2457 for the flowchart arm, also similarly implying poor agreement. CONCLUSIONS: The low agreement amongst practitioners on the prioritization of cancer patient cases for ICU admission existed using both general triage guidelines and guidelines tailored only to cancer patients. The lack of consensus on intensive care unit triage practices in the oncological population exposes a potential barrier to appropriate resource allocation that needs to be addressed.

Reframing Medical Appropriateness: A Case Study Concerning the Use of Life-Sustaining Technologies for a Patient With Profoundly Diminished Quality of Life.

This case study considers the clinical ethics issues of medical appropriateness and quality of life for patients who are critically ill. The case involves a terminally ill cancer patient with a profoundly diminished quality of life and an extremely poor prognosis; his spouse desires to bring him home, where she will arrange to keep him alive for as long as possible via life-sustaining interventions. The analysis engages with the complicated notion of medical appropriateness, both in general and as it pertains to life-sustaining interventions in a critical care setting, and considers the ethical implications of the various ways in which one might understand this concept. It also addresses the significance of quality-of-life determinations, emphasizing the role of individualized values in determining the importance of quality of life for clinical decision-making. The discussion concludes with a description of the two strategies employed by the ethics team in helping to alleviate the medical team's concerns about this case.

Noninvasivepositive pressure ventilation vsinvasive mechanical ventilation as first-line therapy for acute hypoxemic respiratory failure in cancer patients.

PURPOSE: The objective was to describe the characteristics and outcomes of critically ill cancer patients who received noninvasive positive pressure ventilation (NIPPV) vs invasive mechanical ventilation as first-line therapy for acute hypoxemic respiratory failure. MATERIAL AND METHODS: A retrospective cohort study of consecutive adult intensive care unit (ICU) cancer patients who received either conventional invasive mechanical ventilation or NIPPV as first-line therapy for hypoxemic respiratory failure. RESULTS: Of the 1614 patients included, the NIPPV failure group had the greatest hospital length of stay, ICU length of stay, ICU mortality (71.3%), and hospital mortality (79.5%) as compared with the other 2 groups (P < .0001). The variables independently associated with NIPPV failure included younger age (odds ratio [OR], 0.99; 95% confidence interval [CI], 0.98-0.99; P=.031), non-Caucasian race (OR, 1.61; 95% CI, 1.14-2.26; P=.006), presence of a hematologic malignancy (OR, 1.87; 95% CI, 1.33-2.64; P=.0003), and a higher Sequential Organ Failure Assessment score (OR, 1.12; 95% CI, 1.08-1.17; P < .0001). There was no difference in mortality when comparing early vs late intubation (less than or greater than 24 or 48 hours) for the NIPPV failure group. CONCLUSION: Noninvasive positive pressure ventilation failure is an independent risk factor for ICU mortality, but NIPPV patients who avoided intubation had the best outcomes compared with the other groups. Early vs late intubation did not have a significant impact on outcomes.

Two Decades of ICU Utilization and Hospital Outcomes in a Comprehensive Cancer Center.

OBJECTIVE: To investigate ICU utilization and hospital outcomes of oncological patients admitted to a comprehensive cancer center. DESIGN: Observational cohort study. SETTING: The University of Texas MD Anderson Cancer Center. PATIENTS: Consecutive adults with cancer discharged over a 20-year period. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The Cochran-Armitage test for trend was used to evaluate ICU utilization and hospital mortality rates by primary service over time. A negative binomial log linear regression model was fitted to the data to investigate length of stay over time. Among 387,306 adult hospitalized patients, the ICU utilization rate was 12.9%. The overall hospital mortality rate was 3.6%: 16.2% among patients with an ICU stay and 1.8% among non-ICU patients. Among those admitted to the ICU, the mean (SD) admission Sequential Organ Failure Assessment score was 6.1 (3.8) for all ICU patients: 7.3 (4.4) for medical ICU patients and 4.9 (2.8) for surgical ICU patients. Hematologic disorders were associated with the highest hospital mortality rate in ICU patients (42.8%); metastatic disease had the highest mortality rate in non-ICU patients (4.2%); sepsis, pneumonia, and other infections had the highest mortality rate for all inpatients (8.5%). CONCLUSIONS: This study provides a longitudinal view of ICU utilization rates, hospital and ICU length of stay, and severity-adjusted mortality rates. Although the data arise from a single institution, it encompasses a large number of hospital admissions over two decades and can serve as a point of comparison for future oncological studies at similar institutions. More studies of this nature are needed to determine whether consolidation of cancer care into specialized large-volume facilities may improve outcomes, while simultaneously sustaining appropriate resource utilization and reducing unnecessary healthcare costs.

Does Thrombolysis Have a Place in the Cardiopulmonary Resuscitation of Patients With Acute Pulmonary Embolism? A Case of Successful Thrombolysis During Pulmonary Embolism Induced Cardiopulmonary Arrest.

OBJECTIVE: Pulmonary embolism often causes cardiac arrest. When this occurs, thrombolytic therapy is not routinely administered. There are multiple reasons for this, including difficulty with rapidly adequately diagnosing the embolus, the lack of good data supporting the use of thrombolytics during resuscitation, the belief that thrombolytic therapy is ineffective once a patient has already arrested, the difficulty of obtaining thrombolytics at the bedside rapidly enough to administer during a code, and the increased risks of bleeding, particularly with ongoing chest compressions. In this case report, we present a patient who was successfully treated with thrombolytic therapy during pulmonary embolism-induced cardiopulmonary arrest and discuss the role of thrombolytics in cardiopulmonary resuscitation. DESIGN: Case report. SETTING: Surgical ICU in a comprehensive cancer center. PATIENT: A 56-year-old man who developed hypotension, dyspnea, hypoxia, and pulseless electrical activity 10 days after resection of a benign colon lesion with a right hemicolectomy and primary end-to-end anastomosis. INTERVENTIONS: After a rapid bedside echocardiogram suggesting pulmonary embolus, thrombolytic therapy was administered during cardiopulmonary resuscitative efforts. MEASUREMENTS AND MAIN RESULTS: The patient had a return of spontaneous circulation and showed improvement in repeat echocardiographic imaging. He had a prolonged course in the ICU and hospital, but eventually made an essentially complete clinical recovery. CONCLUSION: As bedside echocardiographic technology becomes more rapidly and readily available, the rapid diagnosis of pulmonary embolism and use of thrombolytics during cardiopulmonary resuscitation may need to be more routinely considered a potential therapeutic adjunctive measure.

Place of Death among Hospitalized Patients with Cancer at the End of Life.

BACKGROUND: The majority of hospital deaths in the United States occur after ICU admission. The characteristics associated with the place of death within the hospital are not known for patients with cancer. OBJECTIVE: The study objective was to identify patient characteristics associated with place of death among hospitalized patients with cancer who were at the end of life. METHODS: A retrospective cohort study design was implemented. Subjects were consecutive patients hospitalized between 2003 and 2007 at a large comprehensive cancer center in the United States. Multinomial logistic regression analysis was used to identify patient characteristics associated with place of death (ICU, hospital following ICU, hospital without ICU) among hospital decedents. RESULTS: Among 105,157 hospital discharges, 3860 (3.7%) died in the hospital: 42% in the ICU, 14% in the hospital following an ICU stay, and 44% in the hospital without ICU services. Individuals with the following characteristics had an increased risk of dying in the ICU: nonlocal residence, newly diagnosed hematologic or nonmetastatic solid tumor malignancies, elective admission, surgical or pediatric services. A palliative care consultation on admission was associated with dying in the hospital without ICU services. CONCLUSIONS: Understanding existing patterns of care at the end of life will help guide decisions about resource allocation and palliative care programs. Patients who seek care at dedicated cancer centers may elect more aggressive care; thus the generalizability of this study is limited. Although dying in a hospital may be unavoidable for patients who have uncontrolled symptoms that cannot be managed at home, palliative care consultations with patients and their families in advance regarding end-of-life preferences may prevent unwanted admission to the ICU.

Body position and obstructive sleep apnea in 8-12-month-old infants.

AIM: To determine the association between body position and obstructive events during sleep as determined by polysomnography (PSG) in infants of ages 8-12 months with obstructive sleep apnea (OSA). METHODS: Consecutive nocturnal polysomnograms (NPSGs) of 50 children ages 8-12 months old referred to the sleep disorders center between 1 January 2003 and 1 June 2006 for possible sleep-disordered breathing were retrospectively reviewed. Data on total obstructive apnea index (AI), total obstructive apnea-hypopnea index (AHI), AI by body position, AHI by body position, rapid eye movement (REM) and non-REM sleep AHI and REM and non-REM AI were recorded. RESULTS: The mean age was 9.5+/-1.9S.D. months and 46% of the patients were females. There were no significant differences between the mean non-supine AHI (2.0+/-5.1) and supine AHI (2.5+/-5.4), p=0.63. When comparing specific body positions, there were also no significant differences between the mean supine AHI (2.5+/-5.4), prone AHI (2.9+/-7.3), left-lateral decubitus AHI (1.1+/-6.1), or the right-lateral decubitus AHI (2.5+/-7.6), p=0.71. Additionally, there were also no significant differences between the mean non-supine AI (0.7+/-2.9) and supine AI (1.4+/-3.0), p=0.23, and no differences between the supine AI (0.7+/-2.9), prone AI (1.0+/-2.9), left-lateral decubitus AI (0.3+/-2.9) or the right-lateral decubitus AI (1.1+/-3.0), p=0.44. Children spent an average of 50% of their total sleep time supine. OSA was significantly worse in REM sleep as compared to non-REM sleep (REM AHI 4.3+/-7.3 versus non-REM AHI 1.4+/-3.9, p=0.015; REM AI 5.1+/-4.9 versus non-REM AI 1.5+/-4.9, p<0.001). Mean time in REM sleep was 26% (range 5-42%). CONCLUSIONS: There was no significant effect of body position on sleep-disordered breathing in 8-12 months old infants, although REM sleep represented a significant risk factor for OSA.
