How We Take Care Of Our Elders

Time for some philosophy again. A paper in Neurology released ahead of print confirms something I’m seeing more and more often. Specifically, hospitals can be bad for you, particularly if you are elderly.

The trauma population that we all see is aging with the overall population. Being older predisposes one to injuries that are more likely to require hospitalization. And unfortunately, being in the hospital can have adverse effects. I’m not just talking about the usual culprits such as medical errors or exposure to resistant bacteria. 

The Chicago Health and Aging Project has been tracking a group of elders as they age, and has been making a number of interesting observations. Most recently, they have released information on a correlation between cognitive decline and hospitalization. They tracked nearly 1900 people, of whom 1335 ending up in the hospital for one reason or another (not just trauma). They found that there is a baseline rate of global cognitive decline with age (surprise!). Unfortunately, this rate of decline accelerated 2.4 times in the hospitalized group. Episodic memory scores declined 3.3 times faster, and executive function declined 1.7 times faster. And declines tended to be more pronounced in patients who had more severe illness, longer hospital stay, or advanced age.

There are some issues with the study. It is large, but it is a correlation study nonetheless. Are the effects due to something that happens in the hospital, or are they caused by something not evaluated by the study? It’s also not clear to me whether the declines noted are clinically significant in the daily lives of the people studied, or are just a number on some scale.

Bottom line: Some of the “benign” things that we do to patients in the hospital can have a big impact on their functional outcome. Always remember that they are more fragile than the young trauma patients we take care of. That extra fluid bolus, or dose of morphine, exposure to IV contrast, or noisy neighbor that keeps them from sleeping can make a real difference in how they do. Always consider that everything you do to them might kill them. Then seriously reconsider whether you really, really need to order it at all.

The Handoff: Opportunity for Improvement

Handoffs occur in trauma care all the time. EMS hands the patient off to the trauma team. ED physicians hand off to each other at end of shift. They also hand off patients to the inpatient trauma service. Residents on the trauma service hand off to other residents at the end of their call shift. Attending surgeons hand off to each other as they change service or a call night ends. The same process also occurs with many of the other disciplines involved in patient care as well.

Every one of these handoffs is a potential problem. Our business is incredibly complicated, and given that dozens of details on dozens of patients need to be passed on, the opportunity for error is always present. And the fact that resident work hours are becoming more and more limited increases the need for handoffs and the number of potential errors.

Today, I’ll look at information transfer at the first handoff point, EMS to trauma team. Some literature has suggested that there are 16 specific prehospital data points that affect patient outcome and must be included in the EMS report. How good are we at making sure this happens?

An observational study was carried out at a US Level I trauma center with video recording capabilities in the resuscitation room. Video was reviewed to document the “transmission” part of the EMS report. Trauma chart documentation was also reviewed to see if the “reception” half of the process by the trauma team occurred as well. 

A total of 96 handoffs were reviewed over a one year period. The maximum number of elements in the study was 1536 (96 patients x 16 data elements). The total number “transmitted” was 473, but only 329 of those were “received.” This is not quite as bad as it seems, since 483 points were judged as not applicable by the reviewers. However, this left 580 that were applicable but were not mentioned by EMS. Of the 16 key elements, the median number transmitted was 5, with a range of 1-9. 

This sounds bad. However, the EMS professionals and the physicians have somewhat different objectives. EMS desperately wants to share what they know about the scene and the patient. The trauma team wants to start the evaluation process using their own eyes and hands. What to do?

Bottom line: EMS to trauma team handoffs are a problem for many hospitals. EMS has a lot of valuable information, and the trauma team wants to keep the patient alive. They are both immersed in their own world, working to do what they think is best for the patient. Unfortunately, they could do better if the just worked together a bit more. 

Tomorrow I’ll share a solution to the EMS-trauma team handoff problem.

Clearing The Cervical Spine With MRI

If you follow the trauma literature, clearance of the cervical spine in obtunded patients is confusing at best. Although there is some literature out there that suggests that a good cervical CT alone is adequate, I’m not a believer. I’ve seen a case where the radiologist called the scan normal and a good spine surgeon called an injury and was right. So I’m reluctant to use CT alone because the skills of radiologists vary widely. I might be able to believe a dedicated neuroradiologist, but you can’t guarantee one will be reading your patient’s images.

So I fall back on the routine of clearing the bones with a CT scan, and the ligaments with something else. That something else could be a clinical exam (not available in the obtunded patient), flexion-extension images under fluoroscopy (makes a lot of people nervous), keeping the patient in a collar for weeks (skin breakdown), or an MRI. The problem is that there is little guidance in the literature regarding how good MRI is or the best way to use it.

A recent paper in the Journal of Trauma retrospectively looked at 512 out of 17,000 patients (!) seen over 5 years at one trauma center who had both CT and MRI of the c-spine. They wanted to determine if MRI was of any value in cervical spine clearance. Only 150 met the inclusion criteria (GCS<13, no obvious neuro deficit, normal CT). Half of the MRIs were normal. Of the abnormal ones, 81% showed a ligamentous or soft tissue injury. None were deemed unstable and no specific management was needed for any of the abnormal scans.

The authors interpreted their data as showing that MRI provided no additional useful information. However, numbers were (very) small, so the likelihood of them seeing someone with an unstable ligamentous injury was low. Could it be that they showed that MRI detected stable injuries well, and that they could essentially remove the collar based on that?

Bottom line: We still don’t know how to use MRI for clearance. My bias (no good data I can find) is that it is good in suggesting ligamentous injury via nearby edema. If this injury involves only one set of ligaments, it is very likely a stable one and the collar can be removed. If it involves several groups of ligaments, that is probably not the case. And how soon do we have to get the MRI after injury? Some have suggested that 72 hours is the ideal window because edema decreases afterwards. Sounds reasonable, but I can’t find a shred of evidence in the literature. For now, I’ll get an MRI within 72 hours and if it is abnormal, pass the buck to my neurosurgical colleagues so they can gnash their teeth, too.

I would be very happy if someone can help me out and point me towards some good literature on this topic!

Why Do They Call Them Rounds?

Face it. Everyone uses this term. But where did it come from? After a little digging, I think I’ve found the answer. I’m sure someone will step forward and offer another explanation, but the origins of some of our traditions grow foggy with time.

Supposedly, the term “rounds” was introduced by Sir William Osler, the famed physician, while he was at Johns Hopkins hospital in Baltimore. The original building was built in the 1880s and had a round dome. Osler and his trainees had to walk circular hallways to see their patients. I’ve not been there, but looking at the picture above, the corners of the building appear to be octagonal patient wards as well.

The term has stuck with us, and today just about every discipline from prehospital to rehab medicine use it! If anybody has another theory or correction, please let me know!

Are Femoral Traction Splints Okay In Open Fractures?

Application of traction splints to the femur can be a bit tricky, mostly because of the various indications and contraindications. The company that makes the Hare traction splint gives the sole indication as a suspected femur fracture, and the sole contraindication as an open femur fracture. In my mind, this is a bit too simplistic.

I agree that the traction splint should only be applied on femur fractures, known or suspected. However, there are a few more contraindications:

  • The patient should not have a posterior pelvic fracture. Unfortunately, prehospital providers don’t have xray vision, so they usually can’t tell. If there is any suspicion (pelvic instability, deformity), then don’t use it.
  • The knee joint must be intact. Application of a traction splint across a bad knee will distract the tibia and the femur, potentially causing more injury. Take a good look at the knee. If it’s edematous or discolored, no traction splint.
  • The tibia must not be fractured. As in the previous bullet point, the tibial segments will pull apart before the strong muscles in the thigh allow the femur to reduce.

What about the open fracture scenario? The concern is that contaminated bone will be pulled back into the wound. It’s not really known whether this results in an increased infection rate, but it’s better to be safe and not do it. However, there are two scenarios when applying traction to an open femur fracture is warranted:

  • There is significant bleeding from the wound. Restoring the normal anatomy will create more pressure around the injured tissues and may slow bleeding.
  • The distal pulses are compromised or absent. Most of the time, this is due to kinking of the vessel, not outright damage to it. Pulling it to length may restore normal flow.

Bottom line: Treat traction splints with respect. Keep these tips in mind, but always adhere to your local protocols and procedures first. However, if it’s not covered by them, or you are getting concerned that the patient’s (or their leg’s) wellbeing is at risk, do the right thing!

Thanks to Don Dustin from Mineral County EMS in Colorado for posing this question!
