Timing is everything: Early do-not-resuscitate orders in the intensive care unit and patient outcomes

A Retrospective Analysis of Characteristics Favouring In-Hospital Resuscitation Plan Completion, Their Timing, and Associated Outcomes

Background: Comprehensive resuscitation plans document treatment recommendations, such as 'Not for cardiopulmonary resuscitation'. When created early in admission as a shared decision-making process, these plans support patient autonomy and guide future treatment. The characteristics of patients who have resuscitation plans documented, their timing, and associations with clinical outcomes remain unclear. Objectives: To characterise factors associated with resuscitation plan completion, early completion, and differences in mortality rates and Intensive Care Unit (ICU) admissions based on resuscitation plan status. Methods: This retrospective study analysed non-elective admissions to an Australian tertiary centre from January to June 2021, examining plan completion timing (early < 48 h, late > 48 h) and associations with mortality and ICU admission. Results: Of 13,718 admissions, 5745 (42%) had a resuscitation plan recorded. Most plans (89%) were completed early. Furthermore, 9% of patients died during admission, and 8.2% were admitted to the ICU. For those without resuscitation plans, 0.5% died (p < 0.001), and 9.7% were admitted to the ICU (p = 0.002). Factors associated with plan completion included a medical unit, in-hours admission, older age, female gender, limited English proficiency, and non-Indigenous status. Plans completed late (>48 h) correlated with a higher mortality (14% vs. 9%; p < 0.001) and more ICU admissions (25% vs. 6%; p < 0.001). Aboriginal and/or Torres Strait Islander patients were often overlooked for resuscitation documentation before death. No resuscitation plans were documented for 62% of ICU admissions. Conclusions: Important disparities exist in resuscitation plan completion rates across highly relevant inpatient and demographic groups.

Utility of do-not-resuscitate orders for critically ill infants in the NICU

OBJECTIVE

To better understand the value of DNR orders for critically ill infants in the NICU.

METHODS

A prospective mixed-methods approach was utilized including chart review of infants who died in a regional NICU over a twenty-six-month period and surveys of their neonatologists, neonatal fellows, and nurses.

RESULTS

40 infants died during the study period and 120 staff surveys were completed. Infants with DNR orders were of a higher gestational age at birth and a higher chronological age at death. Nurses were more likely to perceive benefit from DNR orders than physicians. Medical staff recollection of the existence of DNR orders was not always accurate. Time and fear of adding unnecessary emotional burden to parents were identified as barriers to DNR order implementation. An advanced care planning model built on open communication instead of DNR order documentation was deemed the best approach.

CONCLUSION

Though DNR orders are beneficial for a subset of infants, DNR orders are likely not applicable for all infants who die in the NICU. More important is supportive, individualized communication between families and the medical team to ensure quality end-of-life care.

IMPACT

In the adult and pediatric ICU literature, DNR orders are associated with improved qualitative "good death" assessments and decreased familial decision regret. In the NICU, rates of DNR usage aren't well reported and their overall utility is unclear. Though DNR orders can help guide clinical decision making in the NICU and may be associated with higher quality ethical discussion, our data suggest that they are not applicable in all patient cases. We hope that this work will help guide approaches to end-of-life care in the NICU and underscore the importance of frequent, open communication between families and their medical team.

Interprofessional interventions and factors that improve end-of-life care in intensive care units: An integratory review

INTRODUCTION

The changes in health dynamics, caused by the SARS-COVD-2 pandemic and its consequences, generated a greater need to integrate palliative care in the ICU to promote a dignified death.

OBJECTIVE

Identify interprofessional interventions and factors that improve the care of patients at the end of life.

METHODOLOGY

Integrative review, including experimental, quasi-experimental, observational, analytical, and descriptive studies with correlation of variables, published from 2010 to 2021, identified in COCHRANE, CINAHL, CUIDEN, LILACS, SCIELO, Dialnet, PsychInfo, PubMed, PROQUES, PSYCHOLOGY, JOURNALS, SCIENCEDIRECT, with MeSH/DECS terms: "Critical Care", "IntensiveCare" "Life support care", "Palliative care", "Life Quality", "Right to die". 36,271 were identified, after excluding duplicate title, abstract, year of publication, design, theme, methodological quality, objectives, and content, 31 studies were found.

RESULTS

It included 31 articles, 16.7% experimental, 3.3% quasi-experimental, 80% observational, analytical, and descriptive with correlation of variables, 38% published in the United States, 38%, and 19% in Brazil. The pooled sample was 24,779 participants. 32.2% of the studies had level of evidence 1 recommendation (c), and 25.8% level of evidence 2 recommendation (c). This paper synthesises evidence to promote Interprofessional Collaborative Practice in the ICU, improve end-of-life care, and interventions to achieve established therapeutic goals, implement effective care policies, plans, and programmes for critically ill patients and their families; factors that affect palliative care and improve with training and continuing education for health personnel.

CONCLUSION

There are interventions to manage physical and emotional symptoms, training strategies and emotional support aimed at health personnel and family members to improve the quality of death and reduce stays in the ICU. The interdisciplinary team requires training on palliative and end-of-life care to improve care.

Presentation, management, and outcomes of older compared to younger adults with hospital-acquired bloodstream infections in the intensive care unit: a multicenter cohort study

PURPOSE

Older adults admitted to the intensive care unit (ICU) usually have fair baseline functional capacity, yet their age and frailty may compromise their management. We compared the characteristics and management of older (≥ 75 years) versus younger adults hospitalized in ICU with hospital-acquired bloodstream infection (HA-BSI).

METHODS

Nested cohort study within the EUROBACT-2 database, a multinational prospective cohort study including adults (≥ 18 years) hospitalized in the ICU during 2019-2021. We compared older versus younger adults in terms of infection characteristics (clinical signs and symptoms, source, and microbiological data), management (imaging, source control, antimicrobial therapy), and outcomes (28-day mortality and hospital discharge).

RESULTS

Among 2111 individuals hospitalized in 219 ICUs with HA-BSI, 563 (27%) were ≥ 75 years old. Compared to younger patients, these individuals had higher comorbidity score and lower functional capacity; presented more often with a pulmonary, urinary, or unknown HA-BSI source; and had lower heart rate, blood pressure and temperature at presentation. Pathogens and resistance rates were similar in both groups. Differences in management included mainly lower rates of effective source control achievement among aged individuals. Older adults also had significantly higher day-28 mortality (50% versus 34%, p < 0.001), and lower rates of discharge from hospital (12% versus 20%, p < 0.001) by this time.

CONCLUSIONS

Older adults with HA-BSI hospitalized in ICU have different baseline characteristics and source of infection compared to younger patients. Management of older adults differs mainly by lower probability to achieve source control. This should be targeted to improve outcomes among older ICU patients.

Do not resuscitate orders and limitation of therapeutic effort: Ethical challenges in healthcare teams in Chile

The purpose of this paper is to delve into the ethical aspects experienced by the healthcare team when they receive the directive to limit therapeutic effort or a do-not-resuscitate order. From an interpretative, qualitative paradigm with a content analysis approach, a process based on three phases was conducted: pre-analysis in which categories were identified, the projection of the analysis, and inductive analysis. During 2023, interviews were conducted in the clinical setting of a high-complexity hospital in Chile with 56 members of the healthcare teams from critical and emergency units, from which four categories emerged: a) the risk of violating patients' rights by using do-not-resuscitate orders and limiting therapeutic effort; b) the gap in the interpretation of the legal framework addressing the care and attention of patients at the end of life or with terminal illnesses by the healthcare team; c) ethical conflicts in end-of-life care; and d) efficient care versus holistic care in patients with terminal illness. There are significant gaps in bioethics training and aspects of a good death in healthcare teams facing the directive to limit therapeutic effort and not resuscitate. It is suggested to train personnel and work on a consensus guide to address the ethical aspects of a good death.

Diagnostic accuracy of ePOS score in predicting DNR labeling after ICU admission: A prospective observational study (ePOS-DNR)

Background

Resuscitation can sometimes be futile and making a do-not-resuscitate (DNR) decision is in the best interest of the patient. The electronic poor outcome screening (ePOS) score was developed to predict 6-month poor outcomes of critically ill patients. We explored the diagnostic accuracy of the ePOS score in predicting DNR decisions in the intensive care unit (ICU).

Methods

This study was conducted at the ICU of a tertiary referral hospital in Saudi Arabia between March and May 2023. Prospectively, we calculated ePOS scores for all eligible consecutive admissions after 48 h in the ICU and recorded the DNR orders. The ability of the score to predict DNR was explored using logistic regression. Youden's ideal cut-off value was calculated using the DeLong method, and different diagnostic accuracy measures were generated with corresponding 95 % confidence intervals (CIs).

Results

We enrolled 857 patients, 125 received a DNR order and 732 did not. The average ePOS score of DNR and non-DNR patients was 28.2±10.7 and 15.2±9.7, respectively. ePOS score, as a predictor of DNR order, had an area under receiver operator characteristic (AUROC) curve of 81.8 % (95% CI: 79.0 to 84.3, P <0.001). Youden's ideal cut-off value >17 was associated with a sensitivity of 87.2 (95% CI: 80.0 to 92.5, P <0.001), specificity of 63.9 (95% CI: 60.3 to 67.4, P <0.001), positive predictive value of 29.2 (95% CI: 24.6 to 33.8, P <0.001), negative predictive value of 96.7 (95% CI: 95.1 to 98.3, P <0.001), and diagnostic odds ratio 12.1 (95% CI: 7.0 to 20.8, P <0.001).

Conclusions

In this study, the ePOS score performed well as a diagnostic test for patients who will be labeled as DNR during their ICU stay. A cut-off score >17 may help guide clinical decisions to withhold or commence resuscitative measures.

Associations between Present-on-Admission Do-Not-Resuscitate Orders and Short-Term Outcomes in Patients with Pneumonia

OBJECTIVES

Do-not-resuscitate (DNR) orders are used to express patient preferences for cardiopulmonary resuscitation. This study examined whether early DNR orders are associated with differences in treatments and outcomes among patients hospitalized with pneumonia.

METHODS

This is a retrospective cohort study of 768,015 adult patients hospitalized with pneumonia from 2010 to 2015 in 646 US hospitals. The exposure was DNR orders present on admission. Secondary analyses stratified patients by predicted in-hospital mortality. Main outcomes included in-hospital mortality, length of stay, cost, intensive care admission, invasive mechanical ventilation, noninvasive ventilation, vasopressors, and dialysis initiation.

RESULTS

Of 768,015 patients, 94,155 (12.3%) had an early DNR order. Compared with those without, patients with DNR orders were older (mean age 80.1 ± 10.6 years vs 67.8 ± 16.4 years), with higher comorbidity burden, intensive care use (31.6% vs 30.6%), and in-hospital mortality (28.2% vs 8.5%). After adjustment via propensity score weighting, these patients had higher mortality (odds ratio [OR] 2.39, 95% confidence interval [CI] 2.33-2.45) and lower use of intensive therapies such as vasopressors (OR 0.83, 95% CI 0.81-0.85) and invasive mechanical ventilation (OR 0.68, 95% CI 0.66-0.70). Although there was little relationship between predicted mortality and DNR orders, among those with highest predicted mortality, DNR orders were associated with lower intensive care use compared with those without (66.7% vs 80.8%).

CONCLUSIONS

Patients with early DNR orders have higher in-hospital mortality rates than those without, but often receive intensive care. These orders have the most impact on the care of patients with the highest mortality risk.

Limitation of Non-Beneficial Interventions and their Impact on the Intensive Care Unit Costs

Introduction

Using a plan to limit non-beneficial life support interventions has significantly reduced harm and loss of dignity for patients at the end of life. The association of these limitations with patients' clinical characteristics and health care costs in the intensive care unit (ICU) needs further scientific evidence.

Aim of the study

To explore decisions to limit non-beneficial life support interventions, their correlation with patients' clinical data, and their effect on the cost of care in the ICU.

Material and Methods

We included all patients admitted to the general ICU of a hospital in Greece in a two-year (2019-2021) prospective study. Data collection included patient demographic and clinical variables, data related to decisions to limit (withholding, withdrawing) non-beneficial interventions (NBIs), and economic data. Comparisons were made between patients with and without limitation decisions.

Results

NBIs were limited in 164 of 454 patients (36.12%). Patients with limitation decisions were associated with older age (70y vs. 62y; p<0,001), greater disease severity score (APACHE IV, 71 vs. 50; p<0,001), longer length of stay (7d vs. 4.5d; p<0,001), and worse prognosis of death (APACHE IV PDR, 48.9 vs. 17.35; p<0,001). All cost categories and total cost per patient were also higher than the patient without limitation of NBIs (9247,79€ vs. 8029,46€, p<0,004). The mean daily cost has not differed between the groups (831,24€ vs. 832,59€; p<0,716). However, in the group of patients with limitations, all cost categories, including the average daily cost (767.31€ vs. 649.12€) after the limitation of NBIs, were reduced to a statistically significant degree (p<0.001).

Conclusions

Limiting NBIs in the ICU reduces healthcare costs and may lead to better management of ICU resource use.

Evidence Guiding Withdrawal of Mechanical Ventilation at the End of Life: A Review

OBJECTIVE

Distress at the end of life in the intensive care unit (ICU) is common. We reviewed the evidence guiding symptom assessment, withdrawal of mechanical ventilation (WMV) process, support for the ICU team, and symptom management among adults, and specifically older adults, at end of life in the ICU.

SETTING AND DESIGN

Systematic search of published literature (January 1990-December 2021) pertaining to WMV at end of life among adults in the ICU setting using PubMed, Embase, and Web of Science. Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed.

PARTICIPANTS

Adults (age 18 and over) undergoing WMV in the ICU.

MEASUREMENTS

Study quality was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.

RESULTS

Out of 574 articles screened, 130 underwent full text review, and 74 were reviewed and assessed for quality. The highest quality studies pertained to use of validated symptom scales during WMV. Studies of the WMV process itself were generally lower quality. Support for the ICU team best occurs via structured communication and social supports. Dyspnea is the most distressing symptom, and while high quality evidence supports the use of opiates, there is limited evidence to guide implementation of their use for specific patients.

CONCLUSION

High quality studies support some practices in palliative WMV, while gaps in evidence remain for the WMV process, supporting the ICU team, and medical management of distress. Future studies should rigorously compare WMV processes and symptom management to reduce distress at end of life.

Advance care and resuscitation plans in a tertiary hospital: a multimodal approach

OBJECTIVES

Advance care planning (ACP) is the process of documenting a person's preference for medical treatment in the event of future deterioration. This audit aimed to improve discussion and documentation of ACP in patients who die during a hospital admission.

METHODS

We performed a clinical audit in 2021 of inpatients at a tertiary hospital in Sydney, Australia to evaluate the benefit of multimodal interventions to improve ACP compared with previous audits from 2016 and 2011.

RESULTS

In 2021, 97% of audited patients had a documented ACP prior to death compared with 80% in the 2016 audit. The completion of NFR documentation on admission in 2016 was 33%, while in 2021 65% of ACPs were completed within 24 hours of admission.In 2021, 94% of patients had a paper resuscitation form filled; however, identification stickers, which are associated with risk of error, were used in 64%; and 25% of forms were only partially completed. Palliative care was consulted for 44% of patients prior to death; 33% on the day of or prior to death.

CONCLUSIONS

Improvement in prevalence and timing of ACP prior to death is seen in the postintervention audit. A repeat audit in 5 years will be conducted, with interventions focused on improving documentation of ACP.

Quality of End-of-Life Care during the COVID-19 Pandemic at a Comprehensive Cancer Center

To evaluate how the COVID-19 pandemic impacted the quality of end-of-life care for patients with advanced cancer, we compared a random sample of 250 inpatient deaths from 1 April 2019, to 31 July 2019, with 250 consecutive inpatient deaths from 1 April 2020, to 31 July 2020, at a comprehensive cancer center. Sociodemographic and clinical characteristics, the timing of palliative care referral, timing of do-not-resuscitate (DNR) orders, location of death, and pre-admission out-of-hospital DNR documentation were included. During the COVID-19 pandemic, DNR orders occurred earlier (2.9 vs. 1.7 days before death, p = 0.028), and palliative care referrals also occurred earlier (3.5 vs. 2.5 days before death, p = 0.041). During the pandemic, 36% of inpatient deaths occurred in the Intensive Care Unit (ICU) and 36% in the Palliative Care Unit, compared to 48 and 29%, respectively, before the pandemic (p = 0.001). Earlier DNR orders, earlier palliative care referrals, and fewer ICU deaths suggest an improvement in the quality of end-of-life care in response to the COVID-19 pandemic. These encouraging findings may have future implications for maintaining quality end-of-life care post-pandemic.

The affordable care act and do-not-resuscitate orders: Differences by race and ethnicity

BACKGROUND

The Affordable Care Act (ACA) created new payment rules that provided reimbursement for physicians to engage in advance care planning (ACP) conversations with patients. This reimbursement policy has the potential to increase ACP participation, including among racial and ethnic minority groups that have had lower ACP participation.

OBJECTIVES

To examine whether the ACP payment rules were associated with an increase in use of do-not-resuscitate (DNR) orders, particularly among racial and ethnic minority groups, among patients diagnosed with heart failure (HF) in California.

METHODS

The California Office of Statewide Health Planning and Development (OSHPD) Patient Discharge Data Set was used to identify a cohort of elderly patients with a principal diagnosis of HF. This study included 432,520 hospital admissions of patients over the age of 65 with a primary diagnosis of HF between 2012 and 2018. DNR status was identified using International Classification of Diseases, Clinical Modification Ninth and Tenth Revision, codes.

RESULTS

There was a small increase in the utilization of DNR orders overall after the ACA reimbursement policy, but the change was not significantly different for all racial and ethnic groups when compared to white non-Hispanic patients.

CONCLUSIONS

ACP payment rules provided in the ACA were associated with increased utilization of DNR, but the effect was not significantly different for racial and ethnic minorities hospitalized with HF in CA. Additional efforts are needed to increase ACP participation among racial and ethnic minorities.

Advance care planning (ACP) to promote receipt of value-concordant care: Results vary according to patient priorities

BACKGROUND

Benefits of advance care planning (ACP) have recently been questioned by experts, but ACP is comprised of discrete activities. Little is known about which, if any, ACP activities are associated with patients' greater likelihood of receiving value-concordant end-of-life (EoL) care.

OBJECTIVES

To determine which ACP activities [Do-Not-Resuscitate (DNR) order completion, designation of a healthcare proxy (HCP), and/or EoL discussions with physicians], individually and in combination, are associated with the greatest likelihood of receiving value-concordant care, and how results may vary based on patient-reported EoL care priorities.

METHODS

Data from 2 federally-funded, multisite, prospective cohort studies of EoL cancer care from 2002-2019 were analyzed. Cancer patients (N = 278) with metastatic disease refractory to chemotherapy were interviewed for a baseline assessment and followed prospectively until death. Interviews regarding patient priorities occurred a median of 111 days prior to death; data regarding EoL medical care were collected post-mortem from caregiver interviews and medical record abstraction. Patients who 1) prioritized life-extending care, and then received life-extending care (or avoided hospice care), or 2) prioritized comfort-focused care, and then avoided life-extending care (or received hospice care) in the last week of life, were coded as receiving value-concordant care.

RESULTS

After inverse propensity score weighting, the ACP combination associated with the largest proportion of patients receiving value-concordant care was DNR, HCP, and EoL discussions (87% vs. 64% for no ACP activities; OR = 3.91, p = 0.006). In weighted analyses examining each ACP activity individually, DNR orders were associated with decreased likelihood of life-extending care (89% vs. 75%; p = 0.005) and EoL discussions were associated with increased likelihood of hospice care (77% vs. 55%; p = 0.002) among patients prioritizing comfort. ACP activities were not significantly associated with increased likelihood of receiving value-concordant care among patients prioritizing life-extension.

CONCLUSIONS AND RELEVANCE

For patients who prioritize comfort, EoL discussions with physicians and completion of DNR orders may improve odds of receiving value-concordant EoL care. For patients who prioritize life-extension, ACP does not appear to improve odds of receiving value-concordant EoL care.

The Impact of Signing Do-Not-Resuscitate Orders on the Use of Non-Beneficial Life-Sustaining Treatments for Intensive Care Unit Patients: A Retrospective Study

Background: Intensive care medical technology increases the survival rate of critically ill patients. However, life-sustaining treatments also increase the probability of non-beneficial medical treatments given to patients at the end of life. Objective: This study aimed to analyse whether patients with a do-not-resuscitate (DNR) order were more likely to be subject to the withholding of cardiac resuscitation and withdrawal of life-sustaining treatment in the ICU. Methods: This retrospective study collected data regarding the demographics, illness conditions, and life-sustaining treatments of ICU patients who were last admitted to the ICU between 1 January 2016 and 31 December 2017, as determined by the hospital’s electronic medical dataset. Results: We identified and collected data on 386 patients over the two years; 319 (82.6%) signed a DNR before the end. The study found that DNR patients were less likely to receive cardiac resuscitation before death than non-DNR patients. The cardiac resuscitation treatments included chest compressions, electric shock, and cardiotonic drug injections (p < 0.001). However, the life-sustaining treatments were withdrawn for only a few patients before death. The study highlights that an early-documented DNR order is essential. However, it needs to be considered that promoting discussions of time-limited trials might be the solution to helping ICU terminal patients withdraw from non-beneficial life-sustaining treatments.

Incidence and Outcomes of Cardiopulmonary Resuscitation in ICUs: Retrospective Cohort Analysis

OBJECTIVES

We aim to describe incidence and outcomes of cardiopulmonary resuscitation (CPR) efforts and their outcomes in ICUs and their changes over time.

DESIGN

Retrospective cohort analysis.

SETTING

Patient data documented in the Austrian Center for Documentation and Quality Assurance in Intensive Care database.

PATIENTS

Adult patients (age ≥ 18 yr) admitted to Austrian ICUs between 2005 and 2019.

INTERVENTIONS

None.

MEASUREMENTS ANDN MAIN RESULTS

Information on CPR was deduced from the Therapeutic Intervention Scoring System. End points were overall occurrence rate of CPR in the ICU and CPR for unexpected cardiac arrest after the first day of ICU stay as well as survival to discharge from the ICU and the hospital. Incidence and outcomes of ICU-CPR were compared between 2005 and 2009, 2010 and 2014, and 2015 and 2019 using chi-square test. A total of 525,518 first admissions and readmissions to ICU of 494,555 individual patients were included; of these, 72,585 patients (14.7%) died in hospital. ICU-CPR was performed in 20,668 (3.9%) admissions at least once; first events occurred on the first day of ICU admission in 15,266 cases (73.9%). ICU-CPR was first performed later during ICU stay in 5,402 admissions (1.0%). The incidence of ICU-CPR decreased slightly from 4.4% between 2005 and 2009, 3.9% between 2010 and 2014, and 3.7% between 2015 and 2019 (p < 0.001). A total of 7,078 (34.5%) of 20,499 patients who received ICU-CPR survived until hospital discharge. Survival rates varied slightly over the observation period; 59,164 (12.0%) of all patients died during hospital stay without ever receiving CPR in the ICU.

CONCLUSIONS

The incidence of ICU-CPR is approximately 40 in 1,000 admissions overall and approximately 10 in 1,000 admissions after the day of ICU admission. Short-term survival is approximately four out of 10 patients who receive ICU-CPR.

In-hospital end-of-life care in the old: a retrospective study of intensive care unit use and do-not-resuscitate forms in patients deceased in a Belgian university hospital

OBJECTIVES

To explore the quality of in-hospital end-of-life care in adult patients with special attention to those 75 years and older and to make a comparison with the situation 10 years ago.

METHODS

Data were retrospectively collected on adult patients who deceased at Ghent University Hospital between September 2018 and December 2019. The main outcome measures were 'ICU use' and 'presence of DNR forms on non-ICU units' in the final hospitalization. In order to identify possible risk factors for ICU use, logistic regression was performed.

RESULTS

In total, 762 people died, of whom 35% were 75 or older. Just as 10 years ago, one-third (31%) died in the ICU versus 49% of those younger than 75 years (p < 0.001). Of people ≥75 years, 38%, compared to 42% 10 years ago, received an ICU treatment during their final hospitalization. The median length of an ICU stay was 4 versus 3 days 10 years ago. After adjusting for gender, comorbidities and the Charlson Comorbidity Index, factors associated with less ICU use were higher age, active malignancy and dementia (OR 0.838, 0.116 and 0.098 respectively). Seventy-nine percent of older patients on non-ICU wards died with a DNR form (versus 87% 10 years ago).

CONCLUSION

Although there was an increase in the presence of DNR forms in the final hospitalization, no significant differences were seen in actual ICU use compared to 10 years ago. Factors associated with less ICU use were higher age, active malignancy and dementia.

Factors associated with limitation of care after fatal injury

BACKGROUND

There is variability in end-of-life care of trauma patients. Many survive resuscitation but die after limitation of care (LoC). This study investigated LoC at a level I center.

METHODS

Adult trauma deaths between January 2016 and June 2020 were reviewed. Patients were stratified into "full code" versus any LoC (i.e., do not resuscitate, no escalation, or withdrawal of care) and by timing to LoC. Emergency department and "brain" deaths were excluded. Unadjusted logistic regression and Cox proportional hazards were used for analyses. Results include n (%) and odds ratios (ORs) with 95% confidence intervals (CIs), with α = 0.05.

RESULTS

A total of 173 patients were included; 15 patients (8%) died full code and 158 (91%) died after LoC. Seventy-seven patients (48%) underwent incremental LoC. Age (OR, 1.05; 95% CI, 1.02-1.08; p = 0.0010) and female sex (OR, 3.71; 95% CI, 1.01-13.64; p = 0.0487) increased the odds of LoC; number of anatomic injuries (OR, 0.91; 95% CI, 0.85-0.98; p = 0.0146), chest injuries (Abbreviated Injury Scale [AIS] score chest, >3) (OR, 0.02; 95% CI, 0.01-0.26; p = 0.0021), extremity injury (AIS score, >3) (OR, 0.08; 95% CI, 0.01-0.64; p = 0.0170), and hospital complications equal to 1 (OR, 0.21; 95% CI, 0.06-0.78; p = 0.0201) or ≥2 (OR, 0.19; 95% CI, 0.04-0.87; p = 0.0319) decreased the odds of LoC. For those having LoC, final limitations were implemented in <14 days for 83% of patients; markers of injury severity (e.g., Injury Severity Score, Glasgow Coma Scale score, and AIS score) increased the odds of early LoC implementation.

CONCLUSION

Most patients died after LoC was implemented in a timely fashion. Significant head injury increased the odds of LoC. The number of injuries, severe chest and extremity injuries, and increasing number of complications decreased the odds of LoC, presumably because patients died before LoCs were initiated. Understanding factors contributing to end-of-life care could help guide discussions regarding LoCs.

Symptomatic Features and Factors Associated With Do-Not-Resuscitate Consent in Advanced Cancer Patients Admitted to Palliative Care Ward

This study aimed to conduct a retrospective cross-sectional study to investigate the prevalence of symptoms and symptom clusters on sociodemographic and disease characteristics, as well as factors associated with Do-Not-Resuscitate (DNR) consent. Advanced cancer patients were enrolled between 2018 and 2020 with available data. Demographic and clinical data were obtained for analysis from Hospital Information System (HIS) in China. Symptom clusters were extracted by hierarchical cluster analysis. Chi-square test and multiple logistic regression were conducted to investigate the prevalence characteristics of symptoms and influencing factors of DNR consent, respectively. 798 advanced cancer patients were enrolled. The most prevalent symptoms were pain (93%), anorexia (36.5%), and sleep disorders (34.2%). High heart rate was associated with poor performance status and more symptoms. Three clusters were extracted: fatigue-related, respiratory-circulatory system, and digestive system symptom clusters. The incidence of symptoms was statistically significant in age, gender, education level, residence, BMI, performance status, distress score, ADL, and primary pain level. The DNR signature rate was 15.5%. Female, distant metastasis, in-ward rescue, and appearance of dyspnea were independent influencing factors of DNR signature.Chinese hospitalized cancer patients had more symptoms burden that were influenced by various demographic characteristics, especially pain and fatigue-related symptoms. Concerning the trajectory of vital signs is important among advanced cancer patients. The DNR signature rate was lower and our finding indicating an urgency to accurately assess the prognosis and give more palliative care education to enhance DNR rates and early signing in Chinese context.

Intensive care unit (ICU) use has increased among patients with cancer. We sought to define factors associated with ICU admissions among patients with pancreatic cancer and characterize trends in mortality among hospital survivors.

METHODS

The Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database was used to identify patients with pancreatic cancer who underwent resection. Multivariable analyses were conducted to identify factors associated with ICU admission and mortality among hospital survivors.

RESULTS

Among 6422 Medicare beneficiaries who underwent resection of pancreatic cancer, 2386 (37.1%) had an ICU admission. Patients with ICU admissions were more likely to be younger (10-year increase odds ratio [OR]: 0.83, 95% confidence interval [CI]: 0.77-0.89), male (OR: 1.17, 95% CI 1.05-1.30) and undergo resection at a teaching hospital (OR: 1.19, 95% CI: 1.05-1.36). While the majority of patients survived to hospital discharge (n = 2106; 88.3%), a majority of patients (n = 1296; 54.3%) died within 6 months. Among patients who had subsequent ICU admissions, 1- and 5-year survival was only 31.8% and 11.0%, respectively.

CONCLUSIONS

Over one-third of patients with pancreatic cancer had an ICU admission. While most patients survived hospitalization, more than one-half of patients died within 6 months of discharge and two-thirds died within 1 year. These data should serve to guide patient-provider discussions around prognosis relative to ICU utilization.

Explainable Machine Learning to Predict Successful Weaning Among Patients Requiring Prolonged Mechanical Ventilation: A Retrospective Cohort Study in Central Taiwan

Objective: The number of patients requiring prolonged mechanical ventilation (PMV) is increasing worldwide, but the weaning outcome prediction model in these patients is still lacking. We hence aimed to develop an explainable machine learning (ML) model to predict successful weaning in patients requiring PMV using a real-world dataset. Methods: This retrospective study used the electronic medical records of patients admitted to a 12-bed respiratory care center in central Taiwan between 2013 and 2018. We used three ML models, namely, extreme gradient boosting (XGBoost), random forest (RF), and logistic regression (LR), to establish the prediction model. We further illustrated the feature importance categorized by clinical domains and provided visualized interpretation by using SHapley Additive exPlanations (SHAP) as well as local interpretable model-agnostic explanations (LIME). Results: The dataset contained data of 963 patients requiring PMV, and 56.0% (539/963) of them were successfully weaned from mechanical ventilation. The XGBoost model (area under the curve [AUC]: 0.908; 95% confidence interval [CI] 0.864-0.943) and RF model (AUC: 0.888; 95% CI 0.844-0.934) outperformed the LR model (AUC: 0.762; 95% CI 0.687-0.830) in predicting successful weaning in patients requiring PMV. To give the physician an intuitive understanding of the model, we stratified the feature importance by clinical domains. The cumulative feature importance in the ventilation domain, fluid domain, physiology domain, and laboratory data domain was 0.310, 0.201, 0.265, and 0.182, respectively. We further used the SHAP plot and partial dependence plot to illustrate associations between features and the weaning outcome at the feature level. Moreover, we used LIME plots to illustrate the prediction model at the individual level. Additionally, we addressed the weekly performance of the three ML models and found that the accuracy of XGBoost/RF was ~0.7 between weeks 4 and week 7 and slightly declined to 0.6 on weeks 8 and 9. Conclusion: We used an ML approach, mainly XGBoost, SHAP plot, and LIME plot to establish an explainable weaning prediction ML model in patients requiring PMV. We believe these approaches should largely mitigate the concern of the black-box issue of artificial intelligence, and future studies are warranted for the landing of the proposed model.

Code status at time of rapid response activation - Impact on escalation of care?

Background

A code status documents the decision to receive or forgo cardiopulmonary resuscitation in the event of cardiac arrest. For patients who undergo a rapid response team activation (RRT) for possible escalation to an intensive care unit (ICU), the presence or absence of a code status represents a critical inflection point for guiding care decisions and resource utilization. This study characterizes the prevalence of code status at the time of RRT and how code status at RRT affects rates of intensive treatments in the ICU.

Methods

We conducted a single-center retrospective cohort study of 895 rapid response activations occurring over six months. The study included all rapid response team activations for non-obstetric adult inpatients documented in the patient chart. All data was obtained through retrospective chart review. STROBE reporting guidelines were followed.

Results

At the time of RRT activation, 56% of patients had a documented code status. Code status prevalence was much higher among medical rather than surgical services (74% vs. 13%). For patients escalated to the ICU, having a DNR code status at RRT was not associated with decreased odds of receiving cardioactive medications or advanced respiratory support. Before RRT activation, palliative care utilization was low (9%) but more than doubled after RRT (24% before discharge).

Conclusions

Barely half of the patients had an active code status at the time of RRT activation. Similar rates of invasive ICU treatments among full code and DNR patients suggest that documented code statuses do not reflect in-depth goals of care discussions, nor does it guide medical teams caring for the patient at times of decompensation.

Differences in Characteristics, Hospital Care and Outcomes between Acute Critically Ill Emergency Department Patients with Early and Late Do-Not-Resuscitate Orders

Background: A do-not-resuscitate (DNR) order is associated with an increased risk of death among emergency department (ED) patients. Little is known about patient characteristics, hospital care, and outcomes associated with the timing of the DNR order. Aim: Determine patient characteristics, hospital care, survival, and resource utilization between patients with early DNR (EDNR: signed within 24 h of ED presentation) and late DNR orders. Design: Retrospective observational study. Setting/Participants: We enrolled consecutive, acute, critically ill patients admitted to the emergency intensive care unit (EICU) at Taipei Veterans General Hospital from 1 February 2018, to 31 January 2020. Results: Of the 1064 patients admitted to the EICU, 619 (58.2%) had EDNR and 445 (41.8%) LDNR. EDNR predictors were age >85 years (adjusted odd ratios (AOR) 1.700, 1.027–2.814), living in long-term care facilities (AOR 1.880, 1.066–3.319), having advanced cardiovascular diseases (AOR 2.128, 1.039–4.358), “medical staff would not be surprised if the patient died within 12 months” (AOR 1.725, 1.193–2.496), and patients’ family requesting palliative care (AOR 2.420, 1.187–4.935). EDNR patients underwent lesser endotracheal tube (ET) intubation (15.6% vs. 39.9%, p < 0.001) and had reduced epinephrine injection (19.9% vs. 30.3%, p = 0.009), ventilator support (16.7% vs. 37.9%, p < 0.001), and narcotic use (51.1% vs. 62.6%, p = 0.012). EDNR patients had significantly lower 7-day (p < 0.001), 30-day (p < 0.001), and 90-day (p = 0.023) survival. Conclusions: EDNR patients underwent decreased ET intubation and had reduced epinephrine injection, ventilator support, and narcotic use during EOL as well as decreased length of hospital stay, hospital expenditure, and survival compared to LDNR patients.

Dementia and Early Do-Not-Resuscitate Orders Associated With Less Intensive of End-of-Life Care: A Retrospective Cohort Study

BACKGROUND

Dementia is a leading cause of death among US older adults. Little is known about end-of-life care intensity and do-not-resuscitate orders (DNRs) among patients with dementia who die in hospital.

AIM

Examine the relationship between dementia, DNR timing, and end-of-life care intensity.

DESIGN

Observational cohort study.

SETTING/PARTICIPANTS

Inpatient electronic health record extraction for 2,566 persons age 65 and older who died in 2 New York City hospitals in the United States from 2015 to 2017.

RESULTS

Multivariable logistic regression analyses modeled associations between dementia diagnosis, DNR timing, and 6 end-of-life care outcomes. 31% of subjects had a dementia diagnosis; 23% had a DNR on day of hospital admission. Patients with dementia were 18%-40% less likely to have received 4 of 6 types of intensive care (mechanical ventilation AOR: 0.82, 95%CI: 0.67 -1.00; intensive care unit admission AOR: 0.60, 95%CI: 0.49-0.83). Having a DNR on file was inversely associated with staying in the intensive care unit (AOR: 0.57, 95%CI: 0.47-0.70) and avoiding other intensive care measures. DNR placement later during the hospitalization and not having a DNR were associated with more intensive care compared to having a DNR upon admission.

CONCLUSIONS

Having dementia and a do-not resuscitate order upon hospital admission are associated with less intensive end-of-life care. Additional research is needed to understand why persons with dementia receive less intensive care. In clinical practice, encouraging advance care planning prior to and at hospital admission may be particularly important for patients wishing to avoid intensive end-of-life care, including patients with dementia.
