Palliative Care in trauma: Not just for the dying

Clinical Outcomes After Early Palliative Care Evaluations in Geriatric Trauma Intensive Care

INTRODUCTION

Older trauma patients are at risk for worse outcomes compared to younger patients. We hypothesized that early initiation of palliative care (EPC) evaluations, within 72 h of trauma intensive care unit (ICU) admission, would be associated with reduced invasive procedures without a change in hospital mortality.

METHODS

A retrospective cohort review was performed of all trauma patients aged ≥65 y admitted to the trauma (ICU) from January 1, 2016, to December 31, 2021. Patients who received formal palliative care assessments were included. Patient demographics and injury characteristics were evaluated. The primary outcome was ICU length of stay (LOS). Secondary outcomes included code status change, tracheostomy or percutaneous endoscopic gastrostomy placement, use and length of mechanical ventilation, in-hospital mortality, and withdrawal of life-sustaining care.

RESULTS

Two hundred twenty-five patients met inclusion. One hundred and six had EPC while 119 had late palliative care. EPC was associated with decreased ICU LOS (3 versus 9 d, P < 0.001), hospital LOS (3 versus 11 d, P < 0.001), and days on mechanical ventilation (P < 0.001), and fewer tracheostomy (P = 0.007) and percutaneous endoscopic gastrostomy tubes (P = 0.049). There was no difference in withdrawal of life-sustaining care (P = 0.581) or in-hospital mortality (P = 0.172). Pre-existing code status or code status clarification early in admission was associated with EPC (P = 0.003) and decreased interventions.

CONCLUSIONS

EPC is associated with decreased LOS and fewer invasive procedures without a change in hospital mortality. Early discussions regarding code status are helpful in decreasing hospital costs and futile interventions. Further investigation is required to standardize palliative care in this population.

The 2023 WSES guidelines on the management of trauma in elderly and frail patients

BACKGROUND

The trauma mortality rate is higher in the elderly compared with younger patients. Ageing is associated with physiological changes in multiple systems and correlated with frailty. Frailty is a risk factor for mortality in elderly trauma patients. We aim to provide evidence-based guidelines for the management of geriatric trauma patients to improve it and reduce futile procedures.

METHODS

Six working groups of expert acute care and trauma surgeons reviewed extensively the literature according to the topic and the PICO question assigned. Statements and recommendations were assessed according to the GRADE methodology and approved by a consensus of experts in the field at the 10th international congress of the WSES in 2023.

RESULTS

The management of elderly trauma patients requires knowledge of ageing physiology, a focused triage, including drug history, frailty assessment, nutritional status, and early activation of trauma protocol to improve outcomes. Acute trauma pain in the elderly has to be managed in a multimodal analgesic approach, to avoid side effects of opioid use. Antibiotic prophylaxis is recommended in penetrating (abdominal, thoracic) trauma, in severely burned and in open fractures elderly patients to decrease septic complications. Antibiotics are not recommended in blunt trauma in the absence of signs of sepsis and septic shock. Venous thromboembolism prophylaxis with LMWH or UFH should be administrated as soon as possible in high and moderate-risk elderly trauma patients according to the renal function, weight of the patient and bleeding risk. A palliative care team should be involved as soon as possible to discuss the end of life in a multidisciplinary approach considering the patient's directives, family feelings and representatives' desires, and all decisions should be shared.

CONCLUSIONS

The management of elderly trauma patients requires knowledge of ageing physiology, a focused triage based on assessing frailty and early activation of trauma protocol to improve outcomes. Geriatric Intensive Care Units are needed to care for elderly and frail trauma patients in a multidisciplinary approach to decrease mortality and improve outcomes.

Benefits of Early Utilization of Palliative Care Consultation in Trauma Patients

OBJECTIVES

To determine the effects of palliative care consultation if performed within 72 hours of admission on length of stay (LOS), mortality, and invasive procedures.

DESIGN

Retrospective observational study.

SETTING

Single-center level 1 trauma center.

PATIENTS

Trauma patients, admitted to ICU with palliative care consultation.

INTERVENTION

None.

MEASUREMENTS AND MAIN RESULTS

The ICU LOS was decreased in the early palliative care (EPC) group compared with the late palliative care (LPC) group, by 6 days versus 12 days, respectively. Similarly, the hospital LOS was also shorter in the EPC group by 8 days versus 17 days in the LPC group. In addition, the EPC group had lower rates of tracheostomy (4% vs 14%) and percutaneous gastrostomy tubes (4% vs 15%) compared with the LPC group. There was no difference in mortality or discharge disposition between patients in the EPC versus LPC groups. It is noteworthy that the patients who received EPC were slightly older, but there were no other significant differences in demographics.

CONCLUSIONS

EPC is associated with fewer procedures and a shorter amount of time spent in the hospital, with no immediate effect on mortality. These outcomes are consistent with studies that show patients' preferences toward the end of life, which typically involve less time in the hospital and fewer invasive procedures.

The value of compassion: Healthcare savings of palliative care consults in trauma

BACKGROUND

The effects of palliative care (PC) consultation on patient costs and hospitalization metrics in the adult trauma population are unclear.

STUDY DESIGN

We interrogated our Level I trauma center databases from 1/1/19 to 3/31/21 for patients age ≥18 admitted to the trauma service. Patients undergoing PC consult were matched using propensity scoring to those without PC consultation based on age, admission Glasgow Coma Scale score, Injury Severity Score and Head Abbreviated Injury Scale. Total costs, total cost per day, hospital length of stay (LOS), ICU LOS, intubation days, discharge disposition, and rates of nephrology consultation and tracheostomy/feeding tube placements were compared.

RESULTS

140 unique patients underwent PC consultation and were matched to a group not receiving PC consult during the same period. Median total costs in the PC cohort were $39,532 compared to $70,330 in the controls (p<0.01).  Median costs per day in the PC cohort were $3,495 vs $17,970 in the controls (p<0.01).  Median costs per ICU day in the PC cohort were $3,774 vs $17,127 in the controls (p<0.01).  Mean hospital LOS (15.7 vs 7 days), ICU LOS (7.9 vs 2.9 days), and ventilator days (5.1 vs 1.5) were significantly higher in the PC cohort (all p<0.01).  Rates of nephrology consultation (8.6 vs 2.1%, p = 0.03) and tracheostomy/feeding tube placements (12.1 vs 1.4%, p<0.01) were also higher in the PC group.  Patients were more likely to discharge to hospice if they received a PC consult (33.6 vs 2.1%, p<0.01).  Mean time to PC consult was 7.2 days (range 1 hour to 45 days). LOS post-consult correlated positively with time to PC consultation (r = 0.27, p<0.01).

CONCLUSION

Expert PC services are known to alleviate suffering and avert patient goal- and value-incongruent care. While trauma patients demand significant resources, PC consultation offered in concordance with life-sustaining interventions is associated with significant savings to patients and the healthcare system. Given the correlation between LOS following PC consult and time to PC consult, savings may be amplified by earlier PC consultation in appropriate patients.

Neuroinflammatory Biomarkers for Traumatic Brain Injury Diagnosis and Prognosis: A TRACK-TBI Pilot Study

The relationship between systemic inflammation and secondary injury in traumatic brain injury (TBI) is complex. We investigated associations between inflammatory markers and clinical confirmation of TBI diagnosis and prognosis. The prospective TRACK-TBI Pilot (Transforming Research and Clinical Knowledge in Traumatic Brain Injury Pilot) study enrolled TBI patients triaged to head computed tomography (CT) and received blood draw within 24 h of injury. Healthy controls (HCs) and orthopedic controls (OCs) were included. Thirty-one inflammatory markers were analyzed from plasma. Area under the receiver operating characteristic curve (AUC) was used to evaluate discriminatory ability. AUC >0.7 was considered acceptable. Criteria included: TBI diagnosis (vs. OC/HC); moderate/severe vs. mild TBI (Glasgow Coma Scale; GCS); radiographic TBI (CT positive vs. CT negative); 3- and 6-month Glasgow Outcome Scale-Extended (GOSE) dichotomized to death/greater relative disability versus less relative disability (GOSE 1-4/5-8); and incomplete versus full recovery (GOSE <8/ = 8). One-hundred sixty TBI subjects, 28 OCs, and 18 HCs were included. Markers discriminating TBI/OC: HMGB-1 (AUC = 0.835), IL-1b (0.795), IL-16 (0.784), IL-7 (0.742), and TARC (0.731). Markers discriminating GCS 3-12/13-15: IL-6 (AUC = 0.747), CRP (0.726), IL-15 (0.720), and SAA (0.716). Markers discriminating CT positive/CT negative: SAA (AUC = 0.767), IL-6 (0.757), CRP (0.733), and IL-15 (0.724). At 3 months, IL-15 (AUC = 0.738) and IL-2 (0.705) discriminated GOSE 5-8/1-4. At 6 months, IL-15 discriminated GOSE 1-4/5-8 (AUC = 0.704) and GOSE <8/ = 8 (0.711); SAA discriminated GOSE 1-4/5-8 (0.704). We identified a profile of acute circulating inflammatory proteins with potential relevance for TBI diagnosis, severity differentiation, and prognosis. IL-15 and serum amyloid A are priority markers with acceptable discrimination across multiple diagnostic and outcome categories. Validation in larger prospective cohorts is needed. ClinicalTrials.gov Registration: NCT01565551.

Retrospective Review of Trauma ICU Patients With and Without Palliative Care Intervention

BACKGROUND

Older trauma patients present with poor preinjury functional status and more comorbidities. Advances in care have increased the chance of survival from previously fatal injuries with many left debilitated with chronic critical illness and severe disability. Palliative care (PC) is ideally suited to address the goals of care and symptom management in this critically ill population. A retrospective chart review was done to identify the impact of PC consults on hospital length of stay (LOS), ICU LOS, and surgical decisions.

STUDY DESIGN

A Level 1 Trauma Center Registry was used to identify adult patients who were provided PC consultation in a selected 3-year time period. These PC patients were matched with non-PC trauma patients on the basis of age, sex, race, Glasgow Coma Scale, and Injury Severity Score. Chi-square tests and Student's t-tests were used to analyze categorical and continuous variables, respectively. Any p value >0.05 was considered statistically significant.

RESULTS

PC patients were less likely to receive a percutaneous endoscopic gastric tube or tracheostomy. PC patients spent less time on ventilator support, spent less time in the ICU, and had a shorter hospital stay. PC consultation was requested 16.48 days into the patient's hospital stay. Approximately 82% of consults were to assist with goals of care.

CONCLUSION

Specialist PC team involvement in the care of the trauma ICU patients may have a beneficial impact on hospital LOS, ICU LOS, and surgical care rendered. Earlier consultation during hospitalization may lead to higher rates of goal-directed care and improved patient satisfaction.

Palliative Care in the Trauma and Surgical Critical Care Settings: A Narrative Review

BACKGROUND

We aimed to conduct a narrative review of available literature to understand the use of palliative care in the trauma and surgical critical care setting.

METHODS

PubMed, EMBASE, and Google Scholar databases were searched for studies investigating the use of palliative care in the trauma and surgical critical care setting. The search included all studies published through January 9th, 2022. The risk of bias of included studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist tools. Outcomes were summarized in tables and synthesized qualitatively.

RESULTS

A total of 22 studies were included in this review. Key elements of successful palliative care include communication, shared decision-making, family involvement, pain control, establishing a patient's prognosis, and end-of-life management. Approaches to implementation based upon these key elements include best-case/worst-case scenarios, consultation trigger systems, and integrated institutional palliative care programs. Palliative care may reduce hospital length of stay, improve symptom management, and increase patient satisfaction, but the impact on mortality is unclear.

CONCLUSION

The core elements of palliative care have been identified and palliative care has been shown to improve outcomes in trauma and surgical critical care. However, the approaches for implementation still require development. The underutilization of palliative care for trauma patients reveals the need for refining criteria for use of palliative care and improvement in the education of surgical critical care teams to provide primary palliative care services.

Comprehensive comparison between geriatric and nongeriatric patients with trauma

The incidence of geriatric trauma is increasing due to the growing elderly population. Healthcare providers require a global perspective to differentiate critical factors that might alter patients' prognosis.We retrospectively reviewed all adult patients admitted to a trauma center during a 4-year period. We identified 655 adult trauma patients aged from 18 to 64 (nongeriatric group) and 273 trauma patients ≥65 years (geriatric group). Clinical data were collected and compared between the 2 groups.The geriatric group had a higher incidence of trauma and higher Injury Severity Scores than did the nongeriatric group. Fewer geriatric patients underwent surgical treatment (all patients: geriatric vs nongeriatric: 65.9% vs 70.7%; patients with severe trauma: geriatric vs nongeriatric: 27.6% vs 44.5%). Regarding prognosis, the geriatric group exhibited higher mortality rate and less need for long-term care (geriatric vs nongeriatric: mortality: 5.5% vs 1.8%; long-term care: 2.2% vs 5.0%).We observed that geriatric patients had higher trauma incidence and higher trauma mortality rate. Aging is a definite predictor of poor outcomes for trauma patients. Limited physiological reserves and preference for less aggressive treatment might be the main reasons for poor outcomes in elderly individuals.

Improving a Mature Palliative Care Program at a Level I Trauma Center

BACKGROUND

Similar to the significant rise in the geriatric population in the United States, trauma centers have seen an increase in geriatric trauma patients. These patients present with additional challenges such as a higher likelihood of undertriage, mortality, and frailty. In addition, the varying presence of advanced directive documentation increases the importance of early palliative care consultations for geriatric trauma patients.

OBJECTIVE

In 2018, a Level I trauma center in the Midwest reviewed the American College of Surgeons Trauma Quality Improvement Program's Palliative Care Best Practice Guideline to identify opportunities for improvement to strengthen the collaboration between the palliative care consult service and trauma program.

METHODS

The guideline drove improvements, which included documentation changes (i.e., expansion of palliative care consultation triggers, frailty assessment, advanced directives questions, depression screening, and addition of palliative care consultation section on the performance improvement program form) and training (1-hr lecture on palliative care and 5-hr palliative care simulation training) opportunities.

RESULTS

A 3-month manual chart review (March 2019 through May 2019) revealed that by May 2019, 87.2% of admitted geriatric trauma patients received frailty assessments, which surpassed the benchmark (≥85%). In addition, advanced care planning questions (i.e., health care power of attorney, do not resuscitate order, or living will) exceeded the benchmarks set forth by the guideline (≥90%), with all of the questions being asked and documented in 95.7% of those same patient charts by May 2019.

CONCLUSION

This quality improvement project has applicability for trauma centers that treat geriatric trauma patients; using the guidelines can drive changes to meet individual institution needs.

End-tidal to arterial carbon dioxide gradient is associated with increased mortality in patients with traumatic brain injury: a retrospective observational study

Early definitive airway protection and normoventilation are key principles in the treatment of severe traumatic brain injury. These are currently guided by end tidal CO2 as a proxy for PaCO2. We assessed whether the difference between end tidal CO2 and PaCO2 at hospital admission is associated with in-hospital mortality. We conducted a retrospective observational cohort study of consecutive patients with traumatic brain injury who were intubated and transported by Helicopter Emergency Medical Services to a Level 1 trauma center between January 2014 and December 2019. We assessed the association between the CO2 gap-defined as the difference between end tidal CO2 and PaCO2-and in-hospital mortality using multivariate logistic regression models. 105 patients were included in this study. The mean ± SD CO2 gap at admission was 1.64 ± 1.09 kPa and significantly greater in non-survivors than survivors (2.26 ± 1.30 kPa vs. 1.42 ± 0.92 kPa, p < .001). The correlation between EtCO2 and PaCO2 at admission was low (Pearson's r = .287). The mean CO2 gap after 24 h was only 0.64 ± 0.82 kPa, and no longer significantly different between non-survivors and survivors. The multivariate logistic regression model showed that the CO2 gap was independently associated with increased mortality in this cohort and associated with a 2.7-fold increased mortality for every 1 kPa increase in the CO2 gap (OR 2.692, 95% CI 1.293 to 5.646, p = .009). This study demonstrates that the difference between EtCO2 and PaCO2 is significantly associated with in-hospital mortality in patients with traumatic brain injury. EtCO2 was significantly lower than PaCO2, making it an unreliable proxy for PaCO2 when aiming for normocapnic ventilation. The CO2 gap can lead to iatrogenic hypoventilation when normocapnic ventilation is aimed and might thereby increase in-hospital mortality.

The role of palliative care in acute trauma: When is it appropriate?

INTRODUCTION

We hypothesized that trauma providers are reticent to consider palliative measures in acute trauma care.

METHODS

An electronic survey based on four patient scenarios with identical vital signs and serious blunt injuries, but differing ages and frailty scores was sent to WTA and EAST members.

RESULTS

509 (24%) providers completed the survey. Providers supported early transition to comfort care in 85% old-frail, 53% old-fit, 77% young-frail, and 30% young-fit patients. Providers were more likely to transition frail vs. fit patients with (OR = 4.8 [3.8-6.3], p < 0.001) or without (OR = 16.7 [12.5-25.0], p < 0.001) an advanced directive (AD) and more likely to transition old vs. young patients with (OR = 2.0 [1.6-2.6], p < 0.001) or without (OR = 4.2 [2.8-5.0], p < 0.001) an AD.

CONCLUSIONS

In specific clinical situations, there was wide acceptance among trauma providers for the early institution of palliative measures. Provider decision-making was primarily based on patient frailty and age. ADs were helpful for fit or young patients. Provider demographics did not impact decision-making.
