EAST 2015: What If You Don’t Have TEG For Trauma?

January 13, 2015 The Trauma Pro Leave a comment

The new hot items in trauma care are thromboelastography (TEG) and ROTEM (thromboelastometry), a new spin on TEG from the TEM Corporation. These tools allow for in-depth assessment of factors that influence clotting. We know that rapidly recognizing and treating coagulopathy in major trauma patients can reduce mortality. So many trauma centers are clamoring to buy this technology, citing improved patient care as the reason.

But new technology is always expensive, and isn’t always all it’s cracked up to be. TEG and ROTEM require an expensive machine and a never-ending supply of disposable cartridges for use. Some hospitals are reluctant to provide the funds unless there is a compelling clinical need.

Surgeons at the University of Cincinnati compared the use of TEG with good, old-fashioned point-of-care (POC) INR testing in a series of major trauma patients seen at their Level I center.

Here are the factoids:

This was a retrospective review of 628 major trauma patients who received both TEG and POC INR testing using an iSTAT device over a 1.5 year period
Median ISS was 13, and there were many sick patients (20% in shock, 21% received blood, 11% died)
INR correlated with all TEG values, with better correlation in patients in shock
Both INR and TEG correlated well with treatment with blood, plasma, and cryoprecipitate
Processing time was 2 minutes for POC INR vs about 30 minutes for TEG
Charges for POC INR were $22,000 vs $397,000 for TEG(!!)

Bottom line: Point of care INR testing and TEG both correlate well with the need for blood products in major trauma patients. But POC INR is much cheaper and faster. Granted, the TEG gurus will say that you can tailor the products administered to meet the exact needs of the patient. But in all my travels, I have never visited a center that has fully and effectively incorporated TEG or ROTEM into their massive transfusion protocol. Before you make the financial leap to buy these new toys, make sure that you have a very good clinical reason to do so.

EAST 2015: Keeping An ICU Bed Open For Trauma

January 8, 2015 The Trauma Pro Leave a comment

Many busy trauma hospitals have equally busy trauma ICUs. Frequently, trauma patients who need critical care are backed up in the emergency department (ED) while awaiting a bed in such cases. This slows ED throughput for other patients, and increases the possibility of an adverse event while waiting for the ICU bed.

The group at the University of Kentucky in Lexington will present an abstract examining the impact of keeping an open bed in the ICU, as well as having a charge nurse in that unit without a patient assignment to help manage bed availability and staffing.

Here are the factoids:

The study examined highest level trauma activations in the ED requiring ICU admission before implementation of the open bed policy
303 patients pre-implementation were compared to 261 patients post-implementation
The usual demographics were similar for both groups
Time in the ED decreased from 4:17 to 2:34 after the open bed policy was instituted, which was highly significant
ICU length of stay (LOS) for patients who were admitted after the policy was in place decreased despite an increase in ISS, but not significantly so
There was no change in mortality
There was a cost savings of about $1000 per patient due to increased nursing productivity and the decreased LOS

Bottom line: Making the effort to reserve a bed for an incoming trauma patient at all times seems to be well worth it. I have visited many hospitals with incredible logjams of these patients in the ED. Frequently, this has a disproportionate and negative impact on the throughput of other ED patients. Creating such a policy should serve to improve patient flow (and satisfaction: what family wants to spend hours sitting in the ED?) as well save money.

EAST 2015: The “Impact” Of Graduated Driver License Laws

January 7, 2015 The Trauma Pro Leave a comment

Most states have implemented graduated driver license laws for teen drivers over the past 10+ years. Typically, these laws place age limits, approved times of day for driving, and passenger restrictions on young drivers. There is a growing body evidence that these laws have decreased the number of crashes and injuries/fatalities involving new drivers.

A group at the University of Rochester looked at changes in injuries and deaths in new driver related crashes over an extended period in New York state. During this time, the state first implemented graduated licenses, then added further restrictions on passengers under age 21 six years later. Some interesting patterns emerged.

Here are the factoids:

Before graduated licenses were implemented in New York, young drivers made up 4.2% of all fatal crashes and 3.3% of all personal injury crashes
After implementation of graduated licenses (time of day restrictions), the numbers dropped to 2.9% of fatal crashes and 2.7% of personal injury crashes
When the number of youthful passengers was further limited, the fatality rate for those young riders decreased from 43% to 37%. Injury rate also decreased from 41 to 37%.
Driver fatalities and injuries also decreased further after the number of young passengers was limited (numbers not listed in abstract). [Fewer distractions?]

Bottom line: Graduated driver license laws have been passed in nearly every state (with the exception of Vermont [no night-time driving restrictions], and Florida, South Dakota, Virginia [no young passenger restrictions]). It appears that these laws have reduced the number of deaths and injuries in young drivers. But the unintended consequence is that it has also reduced those numbers in the few young passengers they are allowed to carry as well.

EAST 2015: Effect Of An In-Hospital Falls Prevention Program

January 6, 2015 The Trauma Pro Leave a comment

The Centers for Disease Control (CDC) has developed a neatly packaged falls prevention program that clinicians can apply to their elderly patients. Of course, there’s a cute acronym (STEADI = Stopping Elderly Accidents, Deaths, and Injuries), and a lot of slickly packaged reference material. The trauma group at Parkland wondered if the application of this outpatient program on an inpatient population would be helpful.

They looked at elderly patients (age>65) who were admitted for falls. The patients went through STEADI evaluation and interventions, and were compared with a group of historical controls from the prior year.

Here are the factoids:

218 patients went through the STEADI process, and were compared with 194 controls
The usual demographics appeared to be the same in both groups
The fall rate in-hospital was 4.1% for both groups (!)
The fall recidivism rate (fell after discharge) was also the same (2.8% STEADI vs 2.1% controls)

STEADI consists of a number of assessments, including looking for medical conditions and medications that may impair mobility, visual problems, gait and balance testing, footwear evaluation, cognitive screening, and home evaluation. This program was modified by the authors for inpatient use, although the exact modifications were not listed in the abstract.

Bottom line: The application of the CDC STEADI program did not appear to affect falls in-hospital or those after discharge. The authors question whether maintaining the resources ($) to implement this program is justified. The paper does raise that question, but it is not clear what modifications were made to the full program to tailor it to an inpatient population. The fact that nearly 1 in 20 elderly patients are falling in the hospital is concerning, with or without STEADI. What the abstract does confirm is that elderly falls are a huge problem. The CDC notes that 1 in every 3 patients age 65 and older will fall each year! Further evaluation of STEADI and other similar programs is essential to decrease the morbidity and mortality of falls in this age group.

Bowel Sounds, Or Just Plain BS?

January 5, 2015 The Trauma Pro Leave a comment

“Bowel sounds are normal”

How often do you see this on an H&P? Probably a lot more often than they are actually listened for, I would wager. But what do they really mean? Are they important to trauma professionals?

(Un)fortunately, there’s not a whole lot of research that’s looked at this mundane item. And pretty much all of it deals with surgical pathology (e.g. SBO) or the state of the postop abdomen. Over the years, papers have been published about the basics, and I will summarize them below:

Where to listen? Traditionally, auscultation is carried out in all four abdominal quadrants. However, sound transmission is such that listening centrally is usually sufficient.
Listen before palpation? Some papers suggest that palpation may stimulate peristalsis, so you should listen first.
How long should you listen? Reports vary from 30 seconds to 7 minutes (!).
Significance? This is the big question. We’re not expecting to find hyperactive or high pitched sounds suggestive of surgical pathology here. Really, we’re just looking for sounds or no sounds.

But does it make a difference whether we hear anything or not?

Bottom line: In trauma, we don’t care about BS! We’ve all had patients with minimal injury and no bowel sounds, as well as patients with severe abdominal injury and normal ones. We certainly don’t have time to spend several minutes listening for something that has no bearing on our clinical assessment of the patient. Skip this unnecessary part of the physical exam, and continue on with your real evaluation!
