This multicenter study looked at trauma patients with a hemothorax who underwent early tube thoracostomy vs. being observed. They found volume of over 300 ml predicted observation failure. Those observed had shorter hospital stays and  less ICU admissions. Twenty two percent of observation patients required tube thoracostomy. The failed observation group had similar outcomes except longer hospital stays.

Expert consensus recommends not prescribing these eight classes of medications to older adults mostly due to sedative affect and fall risk. 1. Benzodiazepines 2. Barbiturates 3. Muscle relaxants 4. 1st generation antihistamines 5. Sulfanylureas 6.  1st generation antipsychotics 7. Zolpidem  8. Metocloprimide 

A recent study shows marginal improvement in not prescribing these medications to older ED patients.

This single center study looked at diabetic patients who had a POC glucose over 300 and POC ketone over 1.1 and reviewed their diagnosis vs the laboratory accepted diagnosis of DKA. 
“The most recent international consensus laboratory definition of (non-euglycemic) DKA includes a glucose of >?250; a pH <?7.3 or a bicarbonate ??18?mmol/L; and a beta-hydroxybutyrate (BOHB) ??3.0?mmol/L or urine ketone strip ??2+”

This nice review article reminds us “The AO-Spine classification is the most frequently utilized system for thoracic and lumbar fractures, and it categorizes fractures into three types. Type A fractures are compression injuries. In these fractures, the assessment of the involvement of the posterior elements of the vertebral body is essential. Type B fractures are distraction injuries implying tension band involvement, whereas type C fractures are translational or dislocated injuries. The AO-Spine Upper Cervical Injury Classification System… In this classification system, type A injuries have no ligamentous involvement and are considered stable. Type B injuries have tension band or ligamentous injury and may be unstable. Type C injuries are characterized by significant translation and loss of anatomic integrity and are considered unstable."

These authors argue that bystander interventions in the early minutes (they call them the diamond minutes) can have an impact on trauma survival. Particular attention to External hemorrhage control; Airway opening and maintenance; Safe positioning of unconscious patients; Mitigation of early hypoxia and hypothermia could improve survival. We need to publicize this information and undo the years of teaching not to move these patients due to concern of secondary spinal cord injury. Many studies have dispelled that concern.

This article suggest that freeze-dried plasma (FDP) is an acceptable adjunct to whole blood for prehospital resuscitation of trauma patients. “FDP is pathogen-reduced, shelf-stable for up to two years at room temperature, lightweight, and rapidly reconstituted at the point of care.” This method offers an advantage when caring for patients in remote areas with long transport times and has been used by NATO and Canadian armed forces.

In 290 trauma patients diagnosed with dementia prior to injury, when compared to 3000 patients over age 65 without dementia and similar injury severity score, the dementia patients had a much higher rate of discharge to an institution instead of back to home living. This was particularly true of older women.

This article describes a paramedic run community health initiative to assist people with dementia transition to home after an ED visit. They describe:

“Persons living with dementia (PLWD) frequently use the emergency department (ED) for unscheduled care and experience significant challenges during the ED-to-home transition.

The Community Paramedic-led Transitions Intervention (CPTI) is a structured, coaching-based program delivered by community paramedics that includes a home visit and follow-up calls to support PLWD and care partners during the 30?days after ED discharge.”

Could your ED use a program like this to prevent readmissions?

A retrospective study looking at use of transdermal Buprenorphine in older trauma patients with rib fractures found a good safety profile (less naloxone use) and less overall opioid use however no change in overall length of stay or mortality. Adding this to your multimodal pain strategy in older patients with rib fractures seems like a reasonable plan.

A narrative review of literature involving older patients and constipation found:

“Major contributing factors include physical inactivity, sarcopenia, dehydration, inappropriate defecation posture, and polypharmacy, particularly opioids and anticholinergic agents. Importantly, these factors interact through the brain–gut–microbiota axis, contributing not only to gastrointestinal dysfunction but also to systemic outcomes such as frailty, cognitive decline, and increased healthcare burden, thereby supporting a multidimensional disease framework.”

It isn’t as simple as adding a laxative.

Body armor/ bullet resistant vests used by law enforcement are designed to stop penetration by handgun rounds. These rounds have less velocity than rifle rounds. When caring for someone who has been shot while wearing body armor, verify no penetration has occurred and then look for blunt injuries such as rib fractures, liver injuries, pneumothorax, cardiac contusion, vertebral injury, etc. Behind Armor Blunt Trauma (BABT) is the technical term for injuries caused by the transfer of kinetic energy that occurs when these vests are struck.

This narrative review of the trauma literature looking at chronic pain after trauma found: 

  1. Chronic pain occurs in 30–70% of trauma survivors, with prevalence varying by injury type. 
  2. Key risk factors include female sex, younger age, pre-existing pain, psychological distress, and social disadvantage. 
  3. Validated prediction models are available for musculoskeletal trauma
  4. Thoracic trauma is under represented in the pain literature, is often underrecognized, and less protocols are available for treatment
  5. Thoracic pain typically occurs through intercostal nerve damage and persistent pain following thoracic injury
  6. The authors suggest “A trauma-specific, biopsychosocial approach is key to reducing chronic pain and improving recovery.”

This German retrospective study compared the prehospital use of ultrasound by trained paramedics and compared their findings to in-hospital diagnosis and image results. The authors found: 

“Diagnostic accuracy, defined as the concordance between prehospital POCUS-based working diagnoses and final in-hospital diagnoses, was particularly strong for lung ultrasound (pneumothorax, pulmonary edema, pneumonia and pleural effusion; sensitivity 91.7%, specificity 100%) and eFAST (sensitivity 100%, specificity 96.5%), while for the abdominal ultrasound examinations, the specificity was 70% and sensitivity was 71.43%.”

This study sets the stage for future prospective work looking at prehospital US use by paramedics.

This systematic literature review looking at gender differences in trauma care reveals:

  1. Women were older with more low-energy trauma than men. 
  2. Women were more likely to suffer from pelvic and spinal cord injuries. 
  3. Women were more likely to be under-triaged and under-treated.
  4. Sex/gender-based differences in mortality were inconsistent across studies. 
  5. Adjusted mortality appeared similar between women and men

A  modified 2 round Delphi study was used to create 57 learning objectives in geriatric care for European prehospital providers.  Based on in-hospital learning objectives and literature, these experts came up with what appears to be a very reasonable and helpful list of education objectives for pre-hospital providers that could easily apply to emergency medicine learners as a whole. Here is their table:
