In this retrospective study at 103 hospitals of patients over age 65 who received a head CT:
5948 total patients
3177 (53%) were on at least one anti-thrombotic (warfarin, direct oral anticoag, or anti-platelet agent)
781 (13%) had inter cranial hemorrhage. (ICH)
No form of AC showed an increased risk of ICH.
Risk factors for ICH were: “a high-level fall, a Glasgow coma scale of 14, a cutaneous head impact , vomiting, amnesia, a suspected skull vault fracture or of facial bones fracture”
To me this really begs the question are we ordering head CTs on the right patients? Was there any indication of head injury in these patients or did the mere presence of a patient on AC prompt the imaging order? More work should be done to prevent needless imaging cost, patient time in the emergency department and radiologist work load/turn around time.

Question
Over 300 ml of blood on a chest CT in a traumatically injured patient requires a tube thoracostomy. How do you calculate 300 ml of blood on a chest CT?

This review article answers the basic question: when does a traumatic pneumothorax require tube thoracostomy?
“A pneumothorax greater than 20% of the thoracic volume on chest x-ray or greater than 35 mm on CT, measured radially from the chest wall to the lung parenchyma, should be treated with tube thoracostomy. Pneumothoraces smaller than this may be observed; approximately 10% of these will fail observation and require tube thoracostomy treatment.”

This paper outlines the long term effects of surviving a gunshot wound. The authors conclude:
“Firearm injury survivors frequently experience chronic pain, nerve injury, retained bullet fragments that may cause lead toxicity, physical limitations, and PTSD and are at risk for reinjury. In addition to supportive medical and psychiatric care, survivors of firearm injury may benefit from health care–based violence intervention programs.”

Looking at a trauma database of over 3 million patients, 1% presented with prehospital hypothermia (<35 degrees C). These patients had longer hospital stays, higher resource utilization and higher mortality. Even isolated head injury patients with hypothermia had worse outcomes. Rewarming did increase survival slightly for all patients.
Take away: rewarm hypothermic trauma patients as soon as possible to improve mortality.

A scoping review of the literature regarding anxiety in older patients found the follow areas had the biggest impact on anxiety level:
“The variables most strongly associated with anxiety—either as risk or protective factors—are age, female gender, physical activity, physical health conditions, depression, perceived and family support, and social participation. New variables linked to anxiety include body mass index (BMI) and dietary habits.”
Asking questions related to these areas can give you a better picture of your patient’s risk for anxiety.

Looking at 140 patients retrospectively who had abdominal gunshot wounds with associated fractures, prophylactic antibiotics longer than three days did not offer any benefit in preventing fracture infection. Only two patients experienced fracture related infections and 65 total experienced any infection related complications.
From and ED standpoint, it appears reasonable to give a dose of antibiotics in this very rare subset of gunshot wound patients.

This prospective cohort study from Germany found an under triage rate of 58% of trauma patients over 70 years presenting to 12 trauma centers. One area that consistently lead to undertriage was not using a systolic blood pressure under 110 as a criteria for trauma team activation.
The older cohort had 3 times the mortality than younger, were more likely not to arrive by helicopter and mechanism was more commonly ground level fall. This study echos many others in USA and Australia. Better trauma triage criteria are needed for older patients.

A retrospective, single Australian center review of 300 patients who had blunt cerebral vascular injuries found:
-9.8% had an inpatient CVA
-Most occurred in first 72 hours
-Those receiving no anti coagulation or antiplatelets had 28% CVA incidence.
-Those treated had a 3.6% CVA incidence (anti platelets were better than anti coagulation)
-Carotid artery injury was less common than vertebral artery but had higher frequency of CVA
-associated factors: low GCS, rib fractures, severe trauma
Take away: non-treatment of blunt cerebral vascular injuries had higher inpatient stroke risk. Antiplatelet agents such as aspirin and Clopidogrel performed better than anticoagulants

This paper looked at the literature regarding missed injuries in trauma patients. Missed injuries was defined as an injury discovered after the patient was discharged. Most of the missed injuries and causes are not novel but are worthy of remembering.

They suggest a Trauma Tertiary Survey helps prevent missed injury. “Tertiary Survey (TTS), which includes a thorough in-hospital re-examination and a review of diagnostic investigations within the first 24 h, has been shown to significantly reduce the occurrence of missed injuries (1–9 %) in severe trauma patients found after a primary and secondary survey.” This concept is similar to a discharge time out in emergency medicine where all data is reviewed, viral signals are confirmed normal and a team discharge is performed.
The paper offers these suggestions to avoid missed injuries:
1.
Standardize Tertiary Trauma Surveys (TTS).
2.
Be Cognizant of Cognitive Biases (e.g., Anchoring Bias).
3.
Repeat Imaging When Clinically Indicated.
4.
Use Protocolized Imaging Techniques (CT/MRI).
5.
Ensure Radiology-Trauma Communication.
6.
Prioritize High-Risk Populations.
7.
Implement Peer Review or Double-Check Systems.
8.
Encourage a Culture of Collaboration and Humility.
9.
Limit Provider Fatigue and Overload.
10.
Create Tailored Checklists for Subtle Injuries.

Outcomes in traumatic brain injury are improved when physiologic homeostasis is achieved as soon as possible after injury. Here are the American College of Surgeons’ recommendations. Note SBP over 110 and a hemoglobin over 7. A study looking at a more liberal transfusion target showed worse ARDS and no mortality benefit.

An open label pragmatic study in 29 Japanese hospitals randomized septic shock patients over age 65 to either a high (MAP 80-85) or control (65-70) group. They then looked at all cause 90 day mortality. The study was stopped early due to a significantly higher percentage of mortality in the higher MAP group.
The study isn’t blinded and is only done in one country, however it does raise the question of what is the ideal MAP for older septic shock patients.

This study from Great Britain compared fatalities for pedestrians and cyclist struck by motor vehicles based on vehicle body type. They found :
“We conclude that in Great Britain, being hit by an SUV as opposed to a passenger car increases injury severity among pedestrians and cyclists, with the strongest effect in children.“

In mid-2024 the Center for Medicare and Medicaid Services introduced a new quality measure entitled Age Friendly Hospital Measure. The initial phase went into effect 1/1/25. It is built around programs from the American College of Surgeons, the American College of Emergency Physicians as well as the Institute for Healthcare Improvement (IHI). It is modeled around the IHI’s 4M Framework.

These authors looked at 5958 trauma patients arriving at their trauma center with a systolic blood pressure greater than 90. They calculated shock index (heart rate /sbp) for all of these and then looked at who received a blood transfusion within one hour of arrival. 211 patients received blood in that time frame. “Patients were stratified by SI using the following thresholds: ? 0.7, > 0.7 to 0.9, > 0.9 to 1.1, > 1.1 to 1.3, and > 1.3.”
“A main effect was observed for shock index with increased risk for required transfusion for patients with admission shock index >0.7 (P < 0.001). In comparison to shock index of ? 0.7, odds ratios were 2.5(1.7 - 3.8), 8.2(5.4 - 12.2), 24.9(15.1 - 41.1), 59.0(32.0 - 108.6) for each categorical increase in SI.”

Based on a review of 511 patients transferred to a level one trauma center for evaluation of facial fractures, this group developed the Facial Fracture Transfer Guidelines. they found that over half of the patients transferred to them did not require intervention and were discharged within 6 hours. These guidelines are meant to decrease unneeded transfers yet provide appropriate care to those with traumatic facial injuries.

Brain injury guidelines were designed to decrease transfers and neurosurgical consults for adults with head injuries.

A new retrospective study suggests that modified guidelines may be feasible in the pediatric population as well. More data is needed but this is an important step in assuring safe resource utilization in pediatric head injury patients.

In this Israeli study comparing mortality for trauma patients intubated in the emergency department vs the operating room, in hospital mortality was higher for the ED group before controlling for injury severity score and shock. After controlling for injury severity and shock, there was no difference in In hospital mortality. Coupled with previous research, if intubation can wait until after resuscitation and in the OR, that is ideal. And sometimes it just has to happen in the ED and we should be prepared for rapid resuscitation.
