Radiation Exposure From Imaging At Adult vs Pediatric Trauma Centers

Leave a comment

Anyone who reads this blog already knows I am a big believer in well-crafted and focused practice guidelines. And by focused I mean directed toward a clinical problem that typically sees a lot of variability between care providers. Use of imaging is one of these clinical problems. A surgeon may order a certain set of studies for a major blunt trauma patient, and their emergency medicine colleague might order a somewhat different set for someone with the exact same history, physical exam, and injury pattern. Who is right? Neither!

And the variability is even greater when we throw a pediatric patient into the mix. Trauma professionals tend to be even more “generous” when ordering studies on children because they are afraid they might miss something. Unfortunately, this has the potential for overuse of imaging and exposure to unnecessary radiation.

Avery Nathens and a consortium of pediatric trauma centers used the Trauma Quality Improvement Database (TQIP) to review CT imaging practices on children age < 18 over a four year period. Only blunt trauma patients were studied, and the Abbreviated Injury Scale had to be at least 2 for a minimum of one organ system. Transfer patients were excluded because there is no data on imaging for the referring hospital in the TQIP database for them. Comparisons were made between practices at adult trauma centers treating children (ATC), mixed adult/pediatric centers (MTC) and pediatric only trauma centers (PCT).

Here are the factoids:

  • Over 59,000 pediatric trauma patients were identified in the data, and about half (31,081) received at least one CT scan
  • The distribution among the three types of trauma centers was even, with roughly a third seen at each
  • Of the study group 46% had a head CT, 17% a chest CT, and 26% underwent abdominal CT
  • Injured children were more likely to undergo CT if they were older, had a higher ISS, lower motor GCS, were involved in a car crash, or had severe injuries to head or torso
  • Overall CT rates were about the same across the three types of centers (56% ATC, 57% MTC, 43% PTC)
  • Chest CT was performed 8x as much at ATC/MTC vs PTC (!)
  • Abdominal CT was performed 2x as much at ATC/MTC vs PTC
  • Lesser injured children received relatively more CT scans at ATC/MTC when compared to PTC
  • Using standard estimates of cancer risk from all CT scans received, children treated at adult or mixed trauma centers received enough radiation to cause 17 additional lifetime cancers per 100,000 patients
  • About 35 additional lifetime cancers per 100,000 would be caused by the chest and abdominal scans performed at the ATC/MTC centers when compared to pediatric-only centers

Bottom line: This is yet another reason to adopt a well-designed pediatric imaging guideline. Not only are adult centers using CT scanning much more that pediatric-only centers, but they are unnecessarily adding to the lifetime risk for cancer of our children!

As I always recommend, find a well-designed imaging guideline from an established pediatric center and “borrow” it. Sure, it may need a few minor tweaks to fit well with your hospital. That’s okay. Just get it done so your team can begin to order the initial imaging studies consistently and intelligently.

The 30-Minute Rules: Documentation

Leave a comment

In my last post, I reviewed timing for the 30-minute rules. When does the 30-minute timer actually start? When does it stop? Now that you understand those concepts, we can move on to actually documenting those times.

As I noted yesterday, the timer starts when the consultant is called or paged. It should be easy to record this, right? Nope. The problem is that a whole host of people can do this:

  • ED clerk
  • Trauma nurse
  • Attending surgeon
  • Resident
  • Medical student (nooooo)
  • And probably more

This makes it more difficult to find a common place to record the call time. The two possibilities are paper or electronic. The paper trauma flow sheet is usually only available to the trauma nurse. The others will either use a random piece of paper that gets lost, or doesn’t record it at all.

The other option is the electronic medical record (EMR). Everyone involved with the resuscitation probably has access to it. What’s the best option? This depends on your hospital. For paper, develop a process such that one person who has access to the trauma flow sheet (usually the nurse) is responsible for entering the call time. Otherwise, develop a specific template in your EMR so that whoever enters it does it the same way. And make sure that everyone who could possibly write the call time note knows how to properly create it.

Now, what about documenting consultant arrival? This is the most difficult part of the process. Once again, there are two alternatives: human factors or technology. Many programs try to rely on technology. Unfortunately, it is frequently flawed. The EMR timestamp when the consult is entered always  occurs after the patient was seen. Badge swipes can be forgotten. The most reliable method relies on personal responsibility. Your consultant must take a moment to check the time when he or she enters the room to examine the patient. They can then record that time when they write their note. And if they really want to be cool, they can also note the time they were called in the note.

Best practice: Have the trauma attending personally make the call to the specialist. And in that conversation, have them mention that “this is a 30–minute criterion consult.” This ensures that both your surgeon and consultant know that their presence is expected promptly. And maintain an expectation that the consultant will properly document their arrival time.

I hope you enjoyed this series. If you have any comments or questions, or want to share tips from your program, please leave a comment below or shout it out on Twitter.

The 30-Minute Rules: Response Times

Leave a comment

In my last post, I reviewed the first component of the 30-minute rules, the actual criteria themselves. It’s not called a 30-minute response rule for no reason. There is an absolutely required time to respond that has been set at 30 minutes.  Today, I’ll look at an equally important component: the response time itself. Why do we have it, and when does the event start and stop?

So why does a rule like this exist? Is it to punish the providers who are being monitored, torturing them to get to the hospital as quickly as possible? No! As with so many of our performance improvement (PI) filters, they are designed to test many, many things. Some examples for this one are:

  • Recognition of a life or limb threatening condition by the in-hospital providers
  • Communications systems (ED clerk, pagers, phones, etc.)
  • The call schedule system
  • Clinician responsiveness and commitment (orthopedics, neurosurgery)
  • Nursing documentation
  • And more!

What is the actual time interval that must be measured? First, it does not start when the clinical condition in the criterion is recognized. If a patient has a large subdural hematoma with shift on CT scan, a radiologist must bring it to the attention of the advanced practice provider, emergency physician, or surgeon, who must then take the next step. The timer actually starts when the clinician causes the specialist to be notified. This may occur when the clerk pages or calls them, or when the clinicians do it directly.

One point of confusion: the clock does not start when the clinician responds to the page or call. What if they don’t call back for 45 minutes? Do they then have another 30 minutes to get to the hospital? No!! It starts when the first notification goes out.

So when does the clock stop? This one is easy. It occurs when the specialist who has been called gets to the patient’s bedside and begins the assessment.

One final thing about the clock? Does the clinician have to respond within the 30-minute time frame on every patient? Ideally, this would be great but it’s not realistic. There is no guidance in the Orange Book about a threshold. But if past experience is any indication, it is most likely a timely response somewhere around 80% of the time. But strive for perfection!

Tomorrow, I’ll list some ways to address the most challenging part of the 30-minute rules: actually recording the response times. And I’ll provide a best practice to help meet it.

The 30-Minute Rules: What Are They Exactly?

Leave a comment

Yesterday, I talked about the new 30-minute rules for orthopedics and neurosurgery in general terms. Today, I’ll write about the who and what.

The rules state that a service representative “must be present and respond within 30 minutes based on institutional-specific criteria.” The response needs to be in person and not by phone. But who can it be? The Clarification Document states that the response can be met by an orthopedic surgery resident, mid-level provider, or the orthopedic surgeon. However, if a resident or midlevel respond, they must document their communication with the orthopedic surgeon in their note.

The neurosurgery service representative is not as clearly spelled out. However, it is presumed that this person meets the same requirements as for orthopedics: resident, midlevel, or neurosurgeon.

The most important issue the trauma program must address is the selection of the actual criteria.  Here are some tips to guide you:

  • Select only a few. Three is a good number. Any more than this will tax your specialists.
  • Choose good criteria that your orthopedic surgeon or neurosurgeon would absolutely want to be there  in 30 minutes for. See my examples below.
  • Make sure they are very specific. Vague terms like “TBI” or “open fracture” would result in your specialist being called in way too often.
  • Ensure that the criteria do not rely on the judgement of the specialist. For example, language such as “a subdural requiring operative intervention” requires the neurosurgeon to pass judgment from home and should be avoided.
  • One exception to the previous point: futile neurotrauma care. Your neurosurgeon may review the images from outside the trauma bay and pronounce the care futile. However, they should document this clearly in a note in the chart as soon as possible. And they had better not change their mind later.
  • Avoid vague language like “when requested by the trauma team.”

So what are some good criteria? Here are a few:

  • Ortho
    • Mangled extremity
    • Dysvascular limb
    • Compartment syndrome
    • Unstable pelvic fracture
    • Open pelvic fracture with external hemorrhage
  • Neurosurgery (you/they pick the exact numbers)
    • Subdural/epidural > x mm
    • Subdural/epidural with midline shift > x mm
    • Subdural/epidural with impending herniation
    • Open skull fracture with brain extrusion
    • Brain extrusion from nose/ear
    • Decrease in GCS of > x points
    • Unilateral dilated pupil with GCS < x points
    • Spinal cord injury with unstable spine

This is not a comprehensive, list, but hopefully you get the idea. Each center needs to develop their own list, with input from their specialists. Once agreed upon, these should be put into policy and approved at the trauma program operations committee.

Tomorrow: call and response.

Best of AAST #1: The Price of Being a Trauma Center

Leave a comment

The annual meeting of the American Association for the Surgery of Trauma (AAST) begins in two weeks. Today, I will kick off a series of commentaries on many of the abstracts being presented at the meeting. All readers should be aware that I have only the abstracts to work with. As I always caution, final judgement cannot be passed until the full paper has been reviewed. And many of these will not make the jump to light speed and ever get published. So take them with a grain of salt. They may point to some promising developments, but then, maybe not.

First up is a nice analysis on the price of being a trauma center. One of my mentors, Bill Schwab, always used to say that trauma centers are always in a state of “high-tech waiting.” It costs money to keep surgeons in house, other medical and surgical specialists at the ready, and an array of services and equipment available at all hours. Any hospital administrator can tell you that trauma is expensive. But how expensive, exactly?

The trauma group at the Medical Center of Central Georgia in Macon did a detailed analysis of the cost of readiness for trauma centers in the year 2016. The Georgia State Trauma Commission, trauma medical directors, trauma program managers, and financial officers from the Level I and II centers in Georgia determined the various categories and reported their actual costs for each. An independent auditor reviewed the data to ensure reporting consistency. Significant variances were analyzed to ensure accurate information.

Here are the factoids:

  • Costs were lumped into four major categories:  administrative, clinical medical staff, in-house OR, and education/outreach
  • Clinical medical staff was the most expensive component, representing 55% of costs at Level I centers and 65% at Level II
  • Only about $110,000 was spent annually on outreach and education at both Level I and II centers, representing a relative lack of resources for this component.
  • Total cost of being a Level I center is about $10 million per year, and $5 million per year for Level II

Here is a copy of the table with the detailed breakdown of each component:

Bottom line: Yes, it’s expensive to be a trauma center. It’s a good idea for any trauma center wannabe to perform a detailed  analysis to make sure that it makes sense financially. This is most important in areas where there are plenty of trauma centers already.  Tools have been developed to determine how many trauma centers will fit within a given geographic area (see below). Unfortunately, very few if any states use this tool to determine how many centers are reasonable. In come cities, it’s almost like the wild west, with centers popping up at random all over the place. This abstract suggests that an additional analysis is mandatory before taking the plunge into this expensive business.
