The epidemiology of do-not-resuscitate orders in patients with trauma: a community level one trauma center observational experience

Discussing End-of-Life in the Intensive Care Unit: Education Practices in Pulmonary and Critical Care Medicine Fellowship Programs

IntroductionEnd-of-life care (EOLC) is an important aspect of patient management in the Intensive Care Unit (ICU). Poor communication during this time can lead to unnecessary suffering for patients and their families. Although palliative training is required in Pulmonary and Critical Care Medicine (PCCM) fellowship programs, there is significant variability in its delivery, and data on its effectiveness are limited. This study evaluates the implementation and impact of EOLC communication instruction in PCCM fellowship programs.MethodsA web-based survey was administered to PCCM fellows in the United States from December 2023 to February 2024. Statistical analyses were conducted to assess factors influencing fellow confidence in leading EOLC discussions in the ICU.ResultsA total of 167 fellows completed the survey (response rate: 7.4%). Most respondents (61%) reported one or two types of EOLC training in their programs. Nearly half (53%) felt their training was adequate. Fellows who led more EOLC discussions were significantly more confident in doing so (P < 0.001). Greater confidence was also associated with smaller ICU census and stronger faculty mentorship (P < 0.05).ConclusionsPCCM fellows feel more confident in leading EOLC discussions when they have supportive faculty mentors, manageable ICU workloads, and ample experience with these conversations. As nearly half of fellows report insufficient training, integrating these strategies into fellowship curricula is essential for improving EOLC communication.

Identifying Prevalence and Potential Predictors of Do-Not-Attempt-Resuscitation Orders to Facilitate Preoperative Discussions on Code Status

BACKGROUND

Do Not Attempt Resuscitation (DNAR) orders allow patients with life-threatening conditions to decline resuscitation efforts should the need arise. The American Society of Anesthesiologists (ASA) recommends discussions with patients on their code status to clarify and honor their goals of care perioperatively. This project sought to determine the prevalence of DNAR orders and to identify the demographics and potential clinical predictors of DNAR status at the beginning and end of admission, which would help anesthesiologists at our center facilitate these discussions.

METHODS

Factors associated with DNAR status at beginning and at end of hospital stay were determined through univariate logistic regressions. For DNAR status at beginning and end of hospital admission, variables assessed were age at arrival, race, sex, palliative consult, use of palliative care service, length of stay in days, presence of surgery, presence of emergent surgery, care level, and medical service.

RESULTS

Approximately 2.4 percent of the sample had an active DNAR order at the beginning of their hospital admission compared to 7.4 percent at the end of hospital admission. Factors significantly associated with DNAR status at the beginning of the hospital stay were consistent with prior literature (age, palliative care consult or service). However, factors significantly associated with DNAR status at the end of hospital stay that were notable included length of stay, undergoing emergent surgery, higher level of care, and being on the oncology service and medical respiratory intensive care unit.

CONCLUSIONS

This retrospective study allows anesthesiologists at our institution to identify patients who may benefit from a more comprehensive perioperative discussion about code status based on certain clinical characteristics, which may improve quality of care by preventing unwanted resuscitative measures that do not align with a patient's goals of care.

Goals of care discussions and treatment limitation decisions in European acute geriatric units: a one-day cross-sectional study

BACKGROUND

It is important to pursue goal-concordant care and to prevent non-beneficial interventions in older people.

AIM

To describe serious illness communication and decision-making practices in hospitalised older people in Europe.

SETTING/PARTICIPANTS

Data on advance directives, goals of care (GOC) discussions and treatment limitation decisions were collected about patients aged 75-years and older admitted to 23 European acute geriatric units (AGUs).

RESULTS

In this cohort of 590 older persons [59.5% aged 85 and above, 59.3% female, median premorbid Clinical Frailty Score (CFS) 6], a formal advance directive was recorded in 3.3% and a pre-hospital treatment limitation in 14.0% with significant differences between European regions (respectively P < 0.001 and P = 0.018).Most prevalent GOC was preservation of function (46.8%). GOC were discussed with patients in 64.0%, with families in 73.0%, within the interprofessional hospital team in 67.0% and with primary care in 13.4%. The GOC and the extent to which it was discussed differed between European regions (both P < 0.001). The prevalence of treatment limitation decisions was 53.7% with a large difference within and between countries (P < 0.001). The odds of having a treatment limitation decision were higher for patients with pre-hospital treatment limitation decisions (OR 39.1), residing in Western versus Southern Europe (OR 4.8), belonging to an older age category (OR 3.2), living with a higher number of severe comorbidities (OR 2.2) and higher premorbid CFS (OR 1.3).

CONCLUSIONS

There is large variability across European AGUs concerning GOC discussions and treatment limitation decisions. Sharing of information between primary and hospital care about patient preferences is noticeably deficient.

Reality of treatment for severely injured patients: are there age-specific differences?

BACKGROUND

Major trauma and its consequences are one of the leading causes of death worldwide across all age groups. Few studies have conducted comparative age-specific investigations. It is well known that children respond differently to major trauma than elderly patients due to physiological differences. The aim of this study was to analyze the actual reality of treatment and outcomes by using a matched triplet analysis of severely injured patients of different age groups.

METHODS

Data from the TraumaRegister DGU® were analyzed. A total of 56,115 patients met the following inclusion criteria: individuals with Maximum Abbreviated Injury Scale > 2 and < 6, primary admission, from German-speaking countries, and treated from 2011-2020. Furthermore, three age groups were defined (child: 3-15 years; adult: 20-50 years; and elderly: 70-90 years). The matched triplets were defined based on the following criteria: 1. exact injury severity of the body regions according to the Abbreviated Injury Scale (head, thorax, abdomen, extremities [including pelvis], and spine) and 2. level of the receiving hospital.

RESULTS

A total of 2,590 matched triplets could be defined. Traffic accidents were the main cause of severe injury in younger patients (child: 59.2%; adult: 57.9%). In contrast, low falls (from < 3 m) were the most frequent cause of accidents in the elderly group (47.2%). Elderly patients were least likely to be resuscitated at the scene. Both children and elderly patients received fewer therapeutic interventions on average than adults. More elderly patients died during the clinical course, and their outcome was worse overall, whereas the children had the lowest mortality rate.

CONCLUSIONS

For the first time, a large patient population was used to demonstrate that both elderly patients and children may have received less invasive treatment compared with adults who were injured with exactly the same severity (with the outcomes of these two groups being opposite to each other). Future studies and recommendations should urgently consider the different age groups.

Insurance Status and Ethnicity Impact Health Disparities in Rates of Advance Directives in Trauma

INTRODUCTION

Advanced directives (ADs) provide a framework from which families may understand patient's wishes. However, end-of-life planning may not be prioritized by everyone. This analysis aimed to determine what populations have ADs and how they affected trauma outcomes.

METHODS

Adult trauma patients recorded in the American College of Surgeons Trauma Quality Improvement Program (TQIP) from 2013-2015 were included. The primary outcome was presence of an AD. Secondary outcomes included mortality, length of stay (LOS), mechanical ventilation, ICU admission/LOS, withdrawal of life-sustaining measures, and discharge disposition. Multivariable logistic regression models were developed for outcomes.

RESULTS

44 705 patients were included in the analyses. Advanced directives were present in 1.79% of patients. The average age for patients with ADs was 77.8 ± 10.7. African American (odds ratio (OR) .53, confidence intervals [CI] .36-.79) and Asian (OR .22, CI .05-.91) patients were less likely to have ADs. Conversely, Medicaid (OR 1.70, CI 1.06-2.73) and Medicare (OR 1.65, CI 1.25-2.17) patients were more likely to have ADs as compared to those with private insurance. The presence of ADs was associated with increased hospital mortality (OR 2.84, CI 2.19-3.70), increased transition to comfort measures (OR 2.87, CI 2.08-3.95), and shorter LOS (CO -.74, CI -1.26-.22). Patients with ADs had an increased odds of hospice care (OR 4.24, CI 3.18-5.64).

CONCLUSION

Advanced directives at admission are uncommon, particularly among African Americans and Asians. The presence of ADs was associated with increased mortality, use of mechanical ventilation, admission to the ICU, withdrawal of life-sustaining measures, and hospice. Future research should target expansion of ADs among minority populations to alleviate disparities in end-of-life treatment.

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.

Racial and Ethnic Differences in the Prevalence of Do-Not-Resuscitate Orders among Older Adults with Severe Traumatic Brain Injury

Background

Older adults suffering from traumatic brain injury (TBI) are subject to higher injury burden and mortality. Do Not Resuscitate (DNR) orders are used to provide care aligned with patient wishes, but they may not be equitably distributed across racial/ethnic groups. We examined racial/ethnic differences in the prevalence of DNR orders at hospital admission in older patients with severe TBI.

Methods

We conducted a retrospective cohort study using the National Trauma Databank (NTDB) between 2007 to 2016. We examined patients ≥ 65 years with severe TBI. For our primary aim, the exposure was race/ethnicity and outcome was the presence of a documented DNR at hospital admission. We conducted an exploratory analysis of hospital outcomes including hospital mortality, discharge to hospice, and healthcare utilization (intracranial pressure monitor placement, hospital LOS, and duration of mechanical ventilation).

Results

Compared to White patients, Black patients (OR 0.48, 95% CI 0.35-0.64), Hispanic patients (OR 0.54, 95% CI 0.40-0.70), and Asian patients (OR 0.63, 95% CI 0.44-0.90) had decreased odds of having a DNR order at hospital admission. Patients with DNRs had increased odds of hospital mortality (OR 2.16, 95% CI 1.94-2.42), discharge to hospice (OR 2.08, 95% CI 1.75-2.46), shorter hospital LOS (−2.07 days, 95% CI −3.07 to −1.08) and duration of mechanical ventilation (−1.09 days, 95% CI −1.52 to −0.67). There was no significant difference in the utilization of ICP monitoring (OR 0.94, 95% CI 0.78-1.12).

Conclusions

We found significant racial and ethnic differences in the utilization of DNR orders among older patients with severe TBI. Additionally. DNR orders at hospital admission were associated with increased in-hospital mortality, increased hospice utilization, and decreased healthcare utilization. Future studies should examine mechanisms underlying race-based differences in DNR utilization.

Improving mortality in older adult trauma patients: Are we doing better?

BACKGROUND

Older adult trauma is associated with high morbidity and mortality. Individuals older than 65 years are expected to make up more than 21% of the total population and almost 39% of trauma admissions by 2050. Our objective was to perform a national review of older adult trauma mortality and identify associated risk factors to highlight potential areas for improvement in quality of care.

MATERIALS AND METHODS

This is a retrospective cohort study of the National Trauma Data Bank including all patients age ≥65 years with at least one International Classification of Diseases, Ninth Revision, Clinical Modification trauma code admitted to a Level I or II US trauma center between 2007 and 2015. Variables examined included demographics, comorbidities, emergency department vitals, injury characteristics, and trauma center characteristics. Multilevel mixed-effect logistic regression was performed to identify independent risk factors of in-hospital mortality.

RESULTS

There were 1,492,759 patients included in this study. The number of older adult trauma patients increased from 88,056 in 2007 to 158,929 in 2015 (p > 0.001). Adjusted in-hospital mortality decreased in 2014 to 2015 (odds ratio [OR], 0.88; 95% confidence interval [CI], 0.86-0.91) when compared with 2007 to 2009. Admission to a university hospital was protective (OR, 0.83; 95% CI, 0.74-0.93) as compared with a community hospital admission. There was no difference in mortality risk between Level II and Level I admission (OR, 1.00; 95% CI, 0.92-1.08). The strongest trauma-related risk factor for in-patient mortality was pancreas/bowel injury (OR, 2.25; 95% CI, 2.04-2.49).

CONCLUSION

Mortality in older trauma patients is decreasing over time, indicating an improvement in the quality of trauma care. The outcomes of university based hospitals can be used as national benchmarks to guide quality metrics.

Contraindications to the Initiation of Veno-Venous ECMO for Severe Acute Respiratory Failure in Adults: A Systematic Review and Practical Approach Based on the Current Literature

(1) Background: Extracorporeal membrane oxygenation (ECMO) is increasingly used for acute respiratory failure with few absolute but many relative contraindications. The provider in charge often has a difficult time weighing indications and contraindications to anticipate if the patient will benefit from this treatment, a decision that often decides life and death for the patient. To assist in this process in coming to a good evidence-based decision, we reviewed the available literature. (2) Methods: We performed a systematic review through a literature search of the MEDLINE database of former and current absolute and relative contraindications to the initiation of ECMO treatment. (3) Results: The following relative and absolute contraindications were identified in the literature: absolute-refusal of the use of extracorporeal techniques by the patient, advanced stage of cancer, fatal intracerebral hemorrhage/cerebral herniation/intractable intracranial hypertension, irreversible destruction of the lung parenchyma without the possibility of transplantation, and contraindications to lung transplantation; relative-advanced age, immunosuppressed patients/pharmacological immunosuppression, injurious ventilator settings > 7 days, right-heart failure, hematologic malignancies, especially bone marrow transplantation and graft-versus-host disease, SAPS II score ≥ 60 points, SOFA score > 12 points, PRESERVE score ≥ 5 points, RESP score ≤ -2 points, PRESET score ≥ 6 points, and "do not attempt resuscitation" order (DN(A)R status). (4) Conclusions: We provide a simple-to-follow algorithm that incorporates absolute and relative contraindications to the initiation of ECMO treatment. This algorithm attempts to weigh pros and cons regarding the benefit for an individual patient and hopefully assists caregivers to make better, informed decisions.

Comparison of Geriatric Versus Non-geriatric Trauma Patients With Palliative Care Consultations

BACKGROUND

Palliative care in trauma patients is still evolving. The goal was to compare characteristics, outcomes, triggers and timing for palliative care consultations (PCC) in geriatric (≥65 y.o.) and non-geriatric trauma patients.

MATERIALS AND METHODS

Retrospective study included 432 patients from two level 1 trauma centers who received PCC between December 2012 and January 2019. Non-geriatric (n = 61) and geriatric (n = 371) groups were compared for: mechanism of injury (MOI), Injury Severity Score (ISS), Revised Trauma Score (RTS), Glasgow Coma Score (GCS), Do-Not-Resuscitate (DNR) orders, futile interventions (FI), duration of mechanical ventilation (DMV), ICU admissions, ICU and hospital lengths of stay (ICULOS; HLOS), timing to PCC, and mortality. Further propensity matching (PM) analysis compared 59 non-geriatric to 59 Geriatric patients matched by ISS, GCS, and DNR.

RESULTS

Geriatric patients were older (85.2 versus 49.7), with falls as predominant MOI. Non-geriatric patients comprised 14.1% of all patients with PCC and were more severely injured than Geriatrics: with statistically higher ISS (24.1 versus 18.5), lower RTS (5.4 versus 7.0), GCS (7.1 versus 11.5), with predominant MOI being traffic accidents, all P < 0.01. Non-Geriatrics had more ICU admissions (96.7% versus 88.1%), longer ICULOS (10.2 versus 4.7 days), DMV (11.1 versus 4.1 days), less DNR (57.4% versus 73.9%), higher in-hospital mortality (12.5% versus 2.6%), but double the time admission-PCC (11.3 versus 4.3 days) compared to Geriatrics, all P < 0.04. In PM comparison, despite same injury severity, Non-geriatrics had triple the time to PCC, five times the HLOS of geriatrics, and more FI (25.4% versus 3.4%), all P < 0.001.

CONCLUSIONS

PCC remains underutilized in non-geriatric trauma patients. Despite higher injury severity, non-geriatrics received more aggressive treatment, and had three times longer time to PCC, resulting in higher rate of FI than in Geriatrics.

Palliative Care Consultations in Trauma Patients and Role of Do-Not-Resuscitate Orders: Propensity-Matched Study

OBJECTIVE

To delineate characteristics of trauma patients associated with a palliative care consultation (PCC) and to analyze the role of do-not-resuscitate (DNR) orders and related outcomes.

METHODS

Retrospective study included 864 patients from 2 level one trauma centers admitted between 2012 and 2019.  Level 1 trauma centers are designated for admission of the most severe injured patients. Palliative care consultation group of 432 patients who received PCC and were compared to matched control (MC) group of 432 patients without PCC. Propensity matching covariates included Injury Severity Score, mechanism of injury, gender, and hospital length of stay (HLOS). Analysis included patient demographics, injury parameters, intensive care unit (ICU) admissions, ICU length of stay (ICULOS), duration of mechanical ventilation, timing of PCC and DNR, and mortality. Palliative care consultation patients were further analyzed based on DNR status: prehospital DNR, in-hospital DNR, and no DNR (NODNR).

RESULTS

Palliative care consultation compared to MC patients were older, predominantly Caucasian, with more frequent traumatic brain injury (TBI), ICU admissions, and mechanical ventilation. The average time to PCC was 5.3 days. Do-not-resuscitate orders were significantly more common in PCC compared to MC group (71.5% vs 11.1%, P < .001). Overall mortality was 90.7% in PCC and 6.0% in MC (P < .001). In patients with DNR, mortality was 94.2% in PCC and 18.8% in MC. In-hospital DNR-PCC compared to NODNR-PCC patients had shorter ICULOS (5.0 vs 7.3 days, P = .04), HLOS (6.2 vs 13.2 days, P = .006), and time to discharge (1.0 vs 6.3 days, P = .04).

CONCLUSIONS

Advanced age, DNR order, and TBI were associated with a PCC in trauma patients and resulted in significantly higher mortality in PCC than in MC patients. Combination of DNR and PCC was associated with shorter ICULOS, HLOS, and time from PCC to discharge.

Predictors of Advance Care Planning Documentation in Patients With Underlying Chronic Illness Who Died of Traumatic Injury

CONTEXT

Advance care planning (ACP) is difficult in the setting of a life-threatening trauma but may be equally important in this context, especially with increasing numbers of trauma victims being elderly or having multimorbidity.

OBJECTIVES

Identify predictors of absent ACP documentation in the electronic health records of patients with underlying chronic illness who died of traumatic injury.

METHODS

We used death records and electronic health records to identify decedents with chronic life-limiting illness who died of traumatic injury between 2010 and 2015 and to evaluate factors associated with documentation of living wills, durable powers of attorney, or physician orders for life-sustaining treatment.

RESULTS

Only 22% of decedents had ACP documentation at time of injury. Among those without preinjury ACP documentation, 4% completed ACP documentation after injury. In multipredictor analyses, patients were less likely to have ACP documentation at the time of injury if they were younger (P < 0.001), had fewer chronic illnesses (P = 0.002), and had fewer nonsurgical hospitalizations (P = 0.042) in the year before injury. Among patients without ACP documentation before injury, those with fewer postinjury nonsurgical hospitalizations were less likely to complete ACP documentation after injury (P = 0.019).

CONCLUSIONS

Our findings suggest that patient characteristics play an important role in the completion of ACP among patients with chronic life-limiting illness and who died from sudden severe injury. Interventions to improve ACP completion by patients with serious chronic conditions have the potential for increasing goal-concordant care in the event of traumatic injury.

Limitation of Life-Sustaining Care in the Critically Ill: A Systematic Review of the Literature

When life-sustaining treatments (LST) are no longer effective or consistent with patient preferences, limitations may be set so that LSTs are withdrawn or withheld from the patient. Many studies have examined the frequency of limitations of LST in intensive care unit (ICU) settings in the past 30 years. This systematic review describes variation and patient characteristics associated with limitations of LST in critically ill patients in all types of ICUs in the United States. A comprehensive search of the literature was performed by a medical librarian between December 2014 and April 2017. A total of 1,882 unique titles and abstracts were reviewed, 113 were selected for article review, and 36 studies were fully reviewed. Patient factors associated with an increased likelihood of limiting LST included white race, older age, female sex, poor preadmission functional status, multiple comorbidities, and worse illness severity score. Based on several large, multicenter studies, there was a trend toward a higher frequency of limitation of LST over time. However, there is large variability between ICUs in the proportion of patients with limitations and on the proportion of deaths preceded by a limitation. Increases in the frequency of limitations of LST over time suggests changing attitudes about aggressive end-of-life-care. Limitations are more common for patients with worse premorbid health and greater ICU illness severity. While some differences in the frequency of limitations of LST may be explained by personal factors such as race, there is unexplained wide variability between units.

Predictors and outcome of invasive mechanical ventilation in hospitalized patients with sepsis: data from National Inpatient Sample

Background: Sepsis is a significant cause of mechanical ventilation in hospitalized patients. Objective: The aim of our study was to recognize the demographic and clinical characteristics associated with an increased need for invasive mechanical ventilation in hospitalized sepsis patients. Methods: We used National Inpatient Sample database from the years 2009-2011 to identify sepsis patients requiring invasive mechanical ventilation. We compared demographic and clinical characteristics of sepsis patients requiring and not requiring ventilator support and conducted univariate and multivariate analyses to determine odds ratio (OR) of association. Results: A total of 4,827,769 sepsis patients were identified among which 21.38% required invasive ventilation. Multivariate logistic regression [OR (95% CI), p<0.001] determined the following to be associated with increased odds of ventilator use: morbid obesity [1.37 (1.31-1.42)] and age group 35-64 years [1.18 (1.14-1.22)] compared to 18-34 years, whereas females [0.90 (0.88-0.91)] and age >85 years [0.49 (0.47-0.52)] had reduced odds of invasive ventilation. Hyperkalemia [1.12 (1.09-1.16)] and hypernatremia [2.26 (2.16-2.36)] were associated with increased odds while hypokalemia [0.94 (0.91-0.97)] had reduced odds of invasive ventilation. Septic patients requiring IMV had higher length of stay by 9.72 ± 0.17 days, hospitalization cost by US $ 43010.31 ± 988.24 and in-hospital mortality (41.33% vs 8.91%). Conclusion: Sepsis is a major cause of intensive care unit admission and initiation of invasive ventilation. Baseline demographic and clinical features affect the need for invasive ventilation. A clear understanding of these risk factors is integral for an appropriate and timely management.

Do-Not-Resuscitate status as an independent risk factor for patients undergoing surgery for hip fracture

AIM

To determine morbidity and mortality in hip fracture patients and also to assess for any independent associations between Do-Not-Resuscitate (DNR) status and increased post-operative morbidity and mortality in patients undergoing surgical repair of hip fractures.

METHODS

We conducted a propensity score matched retrospective analysis using de-identified data from the American College of Surgeons’ National Surgical Quality Improvement Project (ACS NSQIP) for all patients undergoing hip fracture surgery over a 7 year period in hospitals across the United States enrolled in the ACS NSQIP with and without DNR status. We measured patient demographics including DNR status, co-morbidities, frailty and functional baseline, surgical and anaesthetic procedure data, post-operative morbidity/complications, length of stay, discharge destination and mortality.

RESULTS

Of 9218 patients meeting the inclusion criteria, 13.6% had a DNR status, 86.4% did not. Mortality was higher in the DNR compared to the non-DNR group, at 15.3% vs 8.1% and propensity score matched multivariable analysis demonstrated that DNR status was independently associated with mortality (OR = 2.04, 95%CI: 1.46-2.86, P < 0.001). Additionally, analysis of the propensity score matched cohort demonstrated that DNR status was associated with a significant, but very small increased likelihood of post-operative complications (0.53 vs 0.43 complications per episode; OR = 1.21; 95%CI: 1.04-1.41, P = 0.004). Cardiopulmonary resuscitation and unplanned reintubation were significantly less likely in patients with DNR status.

CONCLUSION

While DNR status patients had higher rates of post-operative complications and mortality, DNR status itself was not otherwise associated with increased morbidity. DNR status appears to increase 30-d mortality via ceilings of care in keeping with a DNR status, including withholding reintubation and cardiopulmonary resuscitation.

Do-Not-Resuscitate Status Is Associated With Increased Mortality But Not Morbidity

BACKGROUND

Do-not-resuscitate (DNR) orders instruct medical personnel to forego cardiopulmonary resuscitation in the event of cardiopulmonary arrest, but they do not preclude surgical management. Several studies have reported that DNR status is an independent predictor of 30-day mortality; however, the etiology of increased mortality remains unclear. We hypothesized that DNR patients would demonstrate increased postoperative mortality, but not morbidity, relative to non-DNR patients undergoing the same procedures.

METHODS

Using the American College of Surgeons National Surgical Quality Improvement Program database for 2007-2013, we performed a retrospective analysis to compare DNR and non-DNR cohorts matched by the most common procedures performed in DNR patients. We employed univariable and multivariable logistic regression to characterize patterns of care in the perioperative period as well as identify independent risk factors for increased mortality and assess for the presence of "failure to rescue."

RESULTS

The most common procedures performed on DNR patients were emergent and centered on immediate symptom relief. When adjusting for preoperative factors, DNR patients were still found to have increased incidence of postoperative mortality (odds ratio 2.54 [2.29-2.82], P < .001) but not postoperative morbidity at 30 days. In addition, cardiopulmonary resuscitative measures and unplanned intubation were found to be less frequent in the DNR cohort.

CONCLUSIONS

These findings suggest that increased mortality is the result of adherence to goals of care rather than "failure to rescue."

End of Life Care and Do Not Resuscitate Orders: How Much Does Age Influence Decision Making? A Systematic Review and Meta-Analysis

With population aging, “do not resuscitate” (DNAR) decisions, pertaining to the appropriateness of attempting resuscitation following a cardiac arrest, are becoming commoner. It is unclear from the literature whether using age to make these decisions represents “ageism.” We undertook a systematic review of the literature using CINAHL, Medline, and the Cochrane database to investigate the relationship between age and DNAR. All 10 studies fulfilling our inclusion criteria found that “do not attempt resuscitation” orders were more prevalent in older patients; eight demonstrated that this was independent of other mediating factors such as illness severity and likely outcome. In studies comparing age groups, the adjusted odds of having a DNAR order were greater in patients aged 75 to 84 and ≥85 years (adjusted odds ratio [AOR] 1.70, 95% confidence interval [CI] = [1.25, 2.33] and 2.96, 95% CI = [2.34, 3.74], respectively), compared with those <65 years. In studies treating age as a continuous variable, there was no significant increase in the use of DNAR with age (AOR 0.98, 95% CI = [0.84, 1.15]). In conclusion, age increases the use of “do not resuscitate” orders, but more research is needed to determine whether this represents “ageism.”

Do-not-resuscitate orders among trauma patients

BACKGROUND

Do-not-resuscitate (DNR) orders are an important means to communicate end-of-life wishes. Previous studies have demonstrated variable prevalence of DNR orders among hospitalized trauma patients.

OBJECTIVE

This study was conducted to identify the prevalence and type of DNR orders among trauma patients and to identify associations of DNR orders with injury severity, length of stay, and whether CPR was performed in cases of cardiac arrest.

METHODS

In this retrospective study, medical records were reviewed for 263 trauma patients at Miami Valley Hospital in Dayton, Ohio, in 2014 with a DNR order.

RESULTS

Among 3394 trauma patients in 2014, 263 (8%) patients had a DNR order. Participants were 43% male and 57% female. The mean age was 76 (range, 16-90+) years. The most common mechanisms of injury included fall (n = 214, 81.4%) and motor vehicle collision (n = 16, 6.1%). Most DNR orders in this patient population were instituted during the hospitalization (n = 176, 67%). The most common types of advance directives included DNR order (n = 224, 85.2%), living will (n = 124, 47.2%), and durable power of health care attorney (n = 126, 47.9%). A minority of patients died during hospitalization (n = 100, 38.0%). Among patients who were deceased, 14 (14.0%) had CPR performed.

CONCLUSIONS

Among trauma patients with DNR orders, most DNR orders were instituted during the hospital admission. Most deceased patients with DNR orders did not have CPR performed during the hospital stay.

Preadmission Do Not Resuscitate advanced directive is associated with adverse outcomes following acute traumatic injury

BACKGROUND

Do Not Resuscitate (DNR) orders have been associated with poor outcomes in surgical patients. There is limited literature on admitted trauma patients with advanced directives indicating DNR status before admission (preadmission DNR [PADNR]).

METHODS

A retrospective review of the trauma registry of a suburban county was carried out for admitted trauma patients with age ≥41 years, who were admitted between 2008 and 2013.

RESULTS

Of 7,937 admitted patients, 327 had a preadmission advanced directive indicating DNR. PADNR patients were significantly older (87 vs 69 years), with more frequent comorbidities, and were more often admitted after a fall (94.2% vs 65.8%). PADNR patients had a higher Injury Severity Score (14 vs 11). They also had significantly increased rates of pneumonia, sepsis, myocardial infarction, and death (33.6% vs 5.9%). On multivariate logistic regression, the presence of a preadmission advanced directive indicating DNR status was independently associated with a 5.2-fold increased odds of mortality.

CONCLUSION

An advanced directive indicating DNR is associated with adverse outcomes following trauma.
