Impact of early do-not-attempt-resuscitation orders on procedures and outcomes of severe sepsis

Unintended Consequences of Code Status in the Intensive Care Unit: What Happens After a Do-Not-Resuscitate Order Is Placed? A Retrospective Cohort Study

Background: Some clinicians suspect that patients with do-not-resuscitate (DNR) orders receive less aggressive care. Extrapolation from code status to goals of care could cause significant harm. This study asked the question: Do DNR orders in the intensive care unit (ICU) lead to a decrease in invasive interventions? Methods: This was a retrospective cohort study of ICU patients from three teaching hospitals. All ICU patients were assessed for inclusion. Exclusion criteria were medical futility and death, comfort care, or ICU discharge <48 hours after DNR initiation. Five hundred thirty-six patients met inclusion criteria. One hundred forty-five were included in the final analysis. Primary outcomes were occurrence of invasive interventions after DNR initiation-surgical operation, central line, ventilation, dialysis, or other procedure. Secondary outcomes were antibiotic administration, blood transfusion, mortality, and discharge location. Results: Patients with DNR orders underwent fewer surgical operations (14.5% vs. 31.1%, p = 0.002), but more central lines (42.1% vs. 23.0%, p = 0.009), ventilator use (49.0% vs. 18.9%, p < 0.001), and dialysis (20.0% vs. 4.1%, p = 0.002), compared with patients without DNR orders. Transfusions and antibiotic use decreased similarly over admission for both groups (transfusions: β = 1.25; p = 0.59; and antibiotics: β = 1.44; p = 0.27). Mortality and hospice discharges were higher for DNR patients (p < 0.001.). Conclusions: DNR status did not decrease the number of nonoperative interventions patients received as compared with full code counterparts. Although differences in populations existed, patients with DNR orders were likely to receive a similar number of invasive interventions. This finding suggests that providers do not wholesale limit these options for patients with code status limitations.

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.

Fluid resuscitation of at least 30 mL/kg was not associated with decreased mortality in patients with infection, signs of hypoperfusion, and a do-not-intubate order

Aim

Administration of at least 30 mL/kg of fluid as fluid resuscitation is recommended for patients with sepsis and signs of hypoperfusion. However, it is not clear whether this is appropriate for patients with a do‐not‐intubate (DNI) order. This study evaluated the association between volume of fluid resuscitation and outcomes in patients with infection, signs of hypoperfusion, and a DNI order in an emergency department.

Methods

This was a single‐center retrospective cohort study. We classified the infected patients with signs of hypoperfusion and a DNI order seen in our emergency department between April 1, 2015 and November 31, 2020 into the standard fluid resuscitation group (≥30 mL/kg) and the restricted fluid resuscitation group (<30 mL/kg). We compared with in‐hospital mortality and the rate of discharge to home in two groups.

Results

Of 367 patients, 149 received standard fluid resuscitation and 218 received restricted fluid resuscitation. In‐hospital mortality was similar in each group (40/149 and 62/218, respectively). Standard fluid resuscitation was not associated with in‐hospital mortality (adjusted odds ratio [aOR], 1.05; 95% confidence interval [CI], 0.62–1.77, P = 0.86), but was associated with a significantly lower rate of discharge to home (aOR, 0.55; 95% CI, 0.30–0.98, P = 0.043). There was no significant difference in respiratory rate or need for oxygen therapy post‐resuscitation between the two groups.

Conclusion

This study suggests that fluid resuscitation may be not beneficial for infected patients with signs of hypoperfusion and a DNI order. Further studies should be conducted on the options for resuscitation management for these patients.

Do not attempt cardiopulmonary resuscitation (DNACPR) decisions in people admitted with suspected COVID-19: Secondary analysis of the PRIEST observational cohort study

AIMS

We aimed to describe the characteristics and outcomes of adults admitted to hospital with suspected COVID-19 according to their DNACPR decisions, and identify factors associated with DNACPR decisions.

METHODS

We undertook a secondary analysis of 13,977 adults admitted to hospital with suspected COVID-19 and included in the Pandemic Respiratory Infection Emergency System Triage (PRIEST) study. We recorded presenting characteristics and outcomes (death or organ support) up to 30 days. We categorised patients as early DNACPR (before or on the day of admission) or late/no DNACPR (no DNACPR or occurring after the day of admission). We undertook descriptive analysis comparing these groups and multivariable analysis to identify independent predictors of early DNACPR.

RESULTS

We excluded 1249 with missing DNACPR data, and identified 3929/12748 (31%) with an early DNACPR decision. They had higher mortality (40.7% v 13.1%) and lower use of any organ support (11.6% v 15.7%), but received a range of organ support interventions, with some being used at rates comparable to those with late or no DNACPR (e.g. non-invasive ventilation 4.4% v 3.5%). On multivariable analysis, older age (p < 0.001), active malignancy (p < 0.001), chronic lung disease (p < 0.001), limited performance status (p < 0.001), and abnormal physiological variables were associated with increased recording of early DNACPR. Asian ethnicity was associated with reduced recording of early DNACPR (p = 0.001).

CONCLUSIONS

Early DNACPR decisions were associated with recognised predictors of adverse outcome, and were inversely associated with Asian ethnicity. Most people with an early DNACPR decision survived to 30 days and many received potentially life-saving interventions.

Do-not-resuscitate orders in patients with community-acquired pneumonia: a retrospective study

Background

To investigate the use of do-not-resuscitate (DNR) orders in patients hospitalized with community-acquired pneumonia (CAP) and the association with mortality.

Methods

We assembled a cohort of 1317 adults hospitalized with radiographically confirmed CAP in three Danish hospitals. Patients were grouped into no DNR order, early DNR order (≤48 h after admission), and late DNR order (> 48 h after admission). We tested for associations between a DNR order and mortality using a cox proportional hazard model adjusted for patient and disease related factors.

Results

Among 1317 patients 177 (13%) patients received a DNR order: 107 (8%) early and 70 (5%) late, during admission. Patients with a DNR order were older (82 years vs. 70 years, p < 0.001), more frequently nursing home residents (41% vs. 6%, p < 0.001) and had more comorbidities (one or more comorbidities: 73% vs. 59%, p < 0.001). The 30-day mortality was 62% and 4% in patients with and without a DNR order, respectively. DNR orders were associated with increased risk of 30-day mortality after adjustment for age, nursing home residency and comorbidities. The association was modified by the CURB-65 score Hazard ratio (HR) 39.3 (95% CI 13.9–110.6), HR 24.0 (95% CI 11.9–48,3) and HR 9.4 (95% CI: 4.7–18.6) for CURB-65 score 0–1, 2 and 3–5, respectively.

Conclusion

In this representative Danish cohort, 13% of patients hospitalized with CAP received a DNR order. DNR orders were associated with higher mortality after adjustment for clinical risk factors. Thus, we encourage researcher to take DNR orders into account as potential confounder when reporting CAP associated mortality.

Perceptions of ICU Care Following Do-Not-Resuscitate Orders: A Military Perspective

Although do-not-resuscitate orders only prohibit cardiopulmonary resuscitation in the case of cardiac arrest, the common initiation of this code status in the context of end-of-life care may lead providers to draw premature conclusions about other goals of care. The aim of this study is to identify concerns regarding care quality in the setting of do-not-resuscitate orders within the Department of Defense and compare differences in perceptions between members of the critical care team.

Design

A cross sectional observational study was conducted.

Setting

This study took place in the setting of critical care within the Department of Defense.

Subjects

All members of the Uniformed Services Section of the Society of Critical Care Medicine were invited to participate.

Interventions

A validated 31-question survey exploring the perceptions of care quality in the setting of do-not-resuscitate status was distributed.

Measurements and Main Results

Exploratory factor analysis was used to categorically group survey questions, and average factor scores were compared between respondent groups using t tests. Responses to individual questions were also analyzed between comparison groups using Fisher exact tests. Factor analysis revealed no significant differences between respondents of different training backgrounds; however, those with do-not-resuscitate training were more likely to agree that active treatment would be pursued (p = 0.024) and that trust and communication would be maintained (p = 0.005). Although 38% of all respondents worry that quality of care will decrease, 93% agree that life-prolonging treatments should be offered. About a third of providers wrongly believed that a do-not-resuscitate order must be reversed prior to an operation.

Conclusions

Although providers across training backgrounds held similar concerns about decreased care quality in the ICU, there is wide belief that the routine and noninvasive interventions are offered as indicated. Those with do-not-resuscitate training were more likely to believe that standards of care continued to be met after code status change.

Association Between the Communication Skills of Physicians and the Signing of Do-Not-Resuscitate Consent for Terminally Ill Patients in Emergency Rooms (Cross-Sectional Study)

Background

The signing of do-not-resuscitate (DNR) consent is mandatory in providing a palliative approach in the end-of-life care for the terminally ill patients and requires an effective communication between the physician and the patients or their family members. This study aimed to investigate the association between the communication skills of physicians who participated in the SHARE (supportive environment, how to deliver the bad news, additional information, reassurance, and emotional support) model course on the patient notification and the signing of do-not-resuscitate (DNR) consent by the terminally ill patients at emergency rooms.

Methods

Between May 1, 2017 and April 30, 2018, a total of 109 terminally ill patients were enrolled in this study, of which 70 had signed a DNR and 39 had not. Data regarding the patients’ medical records, a questionnaire survey completed by family members, and patient observation forms were used for the assessment of physicians’ communication skills during patient notification. The observation form was designed based on the SHARE model. A multivariate logistic regression model was applied to identify the independent significant factors of the patient and family member variables as well as the four main components of the observation form.

Results

The results revealed that knowing how to convey bad news and providing reassurance and emotional support were significantly correlated with a higher rate of signing DNR consent. Additionally, physician-initiated discussion with family members and a predicted limited life expectancy were negative independent significant factors for signing DNR consent.

Conclusion

This study revealed that good communication skills help to increase the signing of DNR consent. The learning of such skills from attendance of the SHARE model course is encouraged for the physicians in the palliative care of terminally ill patients in an emergency room.

The effect of patient code status on surgical resident decision making: A national survey of general surgery residents

BACKGROUND

Multiple studies have demonstrated that, compared with their full code counterparts, patients with do-not-resuscitate or do-not-intubate status have higher in-hospital and postdischarge mortality than predicted by clinical characteristics alone. We sought to determine whether patient code status affects surgical resident decision making.

METHODS

We created an online survey that consisted of 4 vignettes, followed by 10 questions regarding decisions on possible diagnostic and therapeutic interventions. All program directors of Accreditation Council for Graduate Medical Education-accredited general surgery residencies were randomized to receive 1 of 2 survey versions that differed only in the code status of the patients described, with requests to distribute the survey to their residents. Responses to each question were based on a Likert scale.

RESULTS

A total of 194 residents completed the survey, 51% of whom were women, and all years of surgical residency were represented. In all vignettes, patient code status influenced perioperative medical decisions, ranging from initiation of dialysis to intensive care unit transfer. In 2 vignettes, it affected decisions to proceed with indicated emergency operations.

CONCLUSION

When presented with patient scenarios pertaining to clinical decision making, surgical residents tend to assume that patients with a do-not-resuscitate or do-not-intubate code status would prefer to receive less aggressive care overall. As a result, the delivery of appropriate surgical care may be improperly limited unless a patient's goals of care are explicitly stated. It is important for surgical residents to understand that a do-not-resuscitate or do-not-intubate code status should not be interpreted as a "do-not-treat" status.

Do-not-attempt resuscitation independently predict in-hospital mortality in septic patients

INTRODUCTION

Sepsis patients require timely and appropriate treatment in an intensive care setting. However, "do-not-attempt resuscitation" (DNAR) status may affect physicians' priorities and treatment preferences. The aim of this study was to evaluate whether DNAR status affects the outcomes of septic patients.

METHODS

This was a retrospective cohort study included septic patients admitted to the emergency department intensive care unit (ED-ICU) in a university-based teaching hospital during April-November 2015. Septic patients admitted to the ED-ICU were included.

RESULTS

Of the 132 eligible patients, 49.2% (65/132) had DNAR status (median age 80 years old, IQR, 73-86). The overall in-hospital mortality rate was 28.8% (38/132). Non-survivors had a higher percentage of receiving inotropes/vasopressors (52.6% vs 34.0%, p = 0.048), higher median Charlson comorbidity index scores [8.5 (IQR, 7-11.75) vs 8 (IQR, 6-9), p = 0.012], higher APACHE II score [25 (IQR, 20-30.25) vs 20 (IQR, 17-25), p = 0.002], and higher SOFA score [7 (IQR, 6-11) vs 6 (IQR,4-8), p = 0.012]. There was no significant difference in intubation among the two groups. In a multivariate logistic regression analysis, DNAR status was an independent predictor of in-hospital mortality (odds ratio = 6.22, 95% confidence interval (CI) = (2.71-17.88), p < 0.001). The area under the ROC curve for the logistic regression model was 0.84 [95% CI = (0.77-0.92), p < 0.001]. In subgroup analysis, DNAR status remained an independent predictor of mortality among age ≥65 years and ≥80 years.

CONCLUSION

After adjusting for comorbidities, treatments, and illness severity, DNAR status was associated with in-hospital mortality of septic patients. Further studies should evaluate physicians' attitudes toward septic patients with DNAR status.

Sex Differences in "Do Not Attempt Resuscitation" Orders After Out-of-Hospital Cardiac Arrest and the Relationship to Critical Hospital Interventions

PURPOSE

Women who experience out-of-hospital cardiac arrest have similar rates of survival to hospital admission as men; however, women are less likely to survive to hospital discharge. We hypothesized that women would have higher rates of "do not attempt resuscitation" (DNAR) orders and that this order would be associated with lower use of aggressive interventions.

METHODS

We identified adult hospital admissions with a diagnosis of cardiac arrest (ICD-9 427.5) from the 2010 California State Inpatient Dataset. Multivariable logistic regression was used to test the association between patient sex and a DNAR order within the first 24 h of admission, adjusting for patient demographic characteristics and comorbid medical conditions. In secondary analysis, procedures performed after establishment of DNAR order and survival to hospital discharge were compared by sex.

FINDINGS

We analyzed 6562 patients (44% women, 56% men) who experienced out-of-hospital cardiac arrest and survived to hospital admission. In unadjusted analysis, more women than men had establishment of a DNAR order during the first 24 h of admission (23.4% versus 19.3%; P < 0.01). After adjusting for age, race, and comorbid conditions, women remained significantly more likely to have a DNAR order established during the first 24 h of their hospital admission after cardiac arrest compared with men (odds ratio = 1.23; 95% CI, 1.09-1.40). No sex difference was found in procedures used after DNAR order was established.

IMPLICATIONS

Female survivors of cardiac arrest are significantly more likely than men to have a DNAR order established within the first 24 h of in-hospital treatment. The establishment of a DNAR order is associated with patients undergoing fewer procedures than individuals who do not have a DNAR order established. Given that patients who have a DNAR order receive less-aggressive intervention after arrest, it is possible that an early DNAR order may contribute to sex differences in survival to hospital discharge.

Variation in outcomes among 24/7 percutaneous coronary intervention centres for patients resuscitated from out-of-hospital cardiac arrest

BACKGROUND

Patients treated at 24/7 percutaneous coronary intervention (PCI) centres following out-of-hospital cardiac arrest (OHCA) have better outcomes than those treated at non-24/7 PCI centres. However, variation in outcomes between 24/7 PCI centres is not well studied.

OBJECTIVES

To evaluate variation in outcomes among 24/7 PCI centres and to assess stability of 24/7 PCI centre performance.

METHODS

Adult patients in the California Office of Statewide Health Planning and Development Patient Discharge Database with a "present on admission" diagnosis of cardiac arrest admitted to a 24/7 PCI centre from 2011 to 2015 were included. Primary outcome was good neurologic recovery at hospital discharge. Secondary outcomes were survival to hospital discharge, cardiac catheterisation, and DNR orders within 24 h. Data were analysed using mixed effects logistic regression models. Hospitals were ranked each year and overall.

RESULTS

Of 27,122 patients admitted to 128 24/7 PCI centres, 41% (11,184) survived and 27% (7188) had good neurologic recovery. Adjusted rates of good neurologic recovery (18%-39%; p,0.001), survival (32%-51%; p < 0.0001), cardiac catheterisation (11%-49%; p < 0.0001) and DNR orders within 24 h (4.8%-49%; p < 0.0001) varied between 24/7 PCI centres. For the 26 hospitals with mean good neurologic rankings in the top or bottom tenth during 2011-2013, 14 (54%) remained in their respective tenth for 2014-2015.

CONCLUSION

Significant variation exists between 24/7 PCI centres in good neurologic recovery following OHCA and persists over time. Future studies should evaluate hospital-level factors that contribute to these differences in outcomes between 24/7 PCI centres.

End-of-life decisions in emergency patients: prevalence, outcome and physician effect

BACKGROUND

End-of-life decisions (EOLD) represent potentially highly consequential decisions often made in acute situations, such as 'do not attempt resuscitation' (DNAR) choices at emergency presentation.

AIM

We investigated DNAR decisions in an emergency department (ED) to assess prevalence, associated patient characteristics, potential medical and economic consequences and estimate contributions of patients and physicians to DNAR decisions.

DESIGN

Single-centre retrospective observation, including ED patients with subsequent hospitalization between 2012 and 2016. Primary outcome was a DNAR decision and associated patient characteristics. Secondary outcomes were mortality, admission to intensive care unit and use of resources.

METHODS

Associations between DNAR and patient characteristics were analysed using logistic mixed effects models, results were reported as odds ratios (OR). Median odds ratios (MOR) were used to estimate patient and physician contributions to variability in DNAR.

RESULTS

Patients of 10 458 were attended by 315 physicians. DNAR was the choice in 23.3% of patients. Patients' characteristics highly associated with DNAR were age (OR = 4.0, 95% CI = 3.6-4.3) and non-trauma presentation (OR = 2.3, 95% CI = 1.9-2.9). In-hospital mortality was significantly higher (OR = 5.4, CI = 4.0-7.3), and use of resources was significantly lower (OR = 0.7, CI = 0.6-0.8) in patients choosing DNAR. There was a significant effect on DNAR by both patient (MOR = 1.8) and physician (MOR = 2.0).

CONCLUSIONS

DNAR choices are common in emergency patients and closely associated with age and non-trauma presentation. Mortality was significantly higher, and use of resources significantly lower in DNAR patients. Evidence of a physician effect raises questions about the choice autonomy of emergency patients in the process of EOLD.

Effect of platelet-lymphocyte ratio and lactate levels obtained on mortality with sepsis and septic shock

BACKGROUND

Sepsis is a potentially fatal condition with high treatment costs, and is especially common among the elderly population. The emergency management of septic patients has gained importance.

OBJECTIVE

Herein, we investigated the effect of admission lactate levels and the platelet-lymphocyte ratio (PLR) on the 30-day mortality among patients older than 65years who were diagnosed with sepsis and septic shock according to the qSOFA criteria at our hospital's emergency department.

METHODS

This observational study was conducted retrospectively. We obtained information regarding patients' demographic characteristics, comorbid conditions, hemodynamic parameters at admission, initial treatment needs at the emergency department.

RESULTS

131 patients received a diagnosis of sepsis and septic shock at our emergency department in two years. Among these, 45% (n=59) of the patients died within 30days of admission. Forty (30.5%) patients required mechanical ventilation. There was a significant difference between the survival and non-survival groups with regard to systolic and diastolic blood pressures (p=0.013 and 0.045, respectively). There were significant differences between the two groups with respect to the Glasgow Coma Scale score (p<0.001) and BUN levels (p<0.001). The mortality status according to qSOFA scores was revealed a significant difference between the two groups (p<0.001).

CONCLUSION

Our results showed that the patients who died within 30days of admission and those who did not had comparable PLR and lactate levels (p=0.821 and 0.120, respectively). We opine that serial lactate measurements would be more useful than a single admission lactate measurement for the prediction of mortality.

Do-not-resuscitate orders and early mortality in hip fracture patients

Background

factors affecting mortality after hip fracture surgery have been studied extensively. It has been suggested that do-not-resuscitate (DNR) orders are associated with higher mortality in surgical patients due to less aggressive treatment. However, the effect of DNR orders on mortality in hip fracture patients is unknown. The objective of this study was to investigate the effect of DNR orders on early mortality after hip fracture surgery.

Methods

all patients undergoing hip fracture surgery between 2004 and 2015 were included in this retrospective study. Patient characteristics such as age, comorbidities and fracture type were collected, as were resuscitation preferences. Multivariable logistic regression analysis was performed to identify independent risk factors for early mortality.

Results

a total of 1,803 patients were analysed, of which 823 (45.6%) had DNR orders. DNR patients were older, more often female, had lower haemoglobin levels and more comorbidities when compared with non-DNR patients. The unadjusted effect of DNR orders on mortality was high (OR: 2.39; P < 0.001). Multivariable analysis demonstrated that increased age, male gender, higher American Society of Anesthesiologists score, low admission haemoglobin, living in an institution, high Charlson Comorbidity Index and delay to surgery were associated with increased early mortality after hip fracture surgery. There was no independent effect of DNR orders on mortality after adjustment for these variables (P = 0.735).

Conclusions

DNR patients have higher mortality rates due to poor health status. Resuscitation preferences on their own are not associated with early mortality after hip fracture surgery.
