One of the long-held beliefs in trauma care relates to the so-called “golden hour.” Patients who receive definitive care promptly do better, we are told. In most trauma centers, the bulk of this early care takes place in the emergency department. However, for a variety of reasons, throughput in the ED can be slow. Could extended periods of time spent in the ED after patient arrival have an impact on survival?
Wake Forest looked at their experience with nearly 4,000 trauma activation patients who were not taken to the OR immediately and who stayed in the ED for up to 5 hours. They looked at the impact of ED dwell time on in-hospital mortality, length of stay and ventilator days.
Overall mortality was 7%, and the average time in the ED was 3 hours and 15 minutes. The investigators set a reasonable but arbitrary threshold of 2 hours to try to get trauma activation patients out of the ED. When they looked at their numbers, they found that mortality increased (7.8% vs 4.3%) and that hospital and ICU lengths of stay were longer in the longer ED stay group. Hospital mortality increased with each hour spent in the ED, and 8.3% of patients staying between 4 and 5 hours dying. ED length of stay was an independent predictor for mortality even after correcting for ISS, RTS and age. The most common cause of death was late complications from infection.
Why is this happening? Patients staying longer in the ED between 2 and 5 hours were more badly injured but not more physiologically abnormal. This suggests that diagnostic studies or consultations were being performed. The authors speculated that the knowledge, experience and protocols used in the inpatient trauma unit were not in place in the ED, contributing to this effect.
Bottom line: This is an interesting retrospective study. It reflects the experience of only one hospital and the results could reflect specific issues found only at Wake Forest. However, shorter ED times are generally better for other reasons as well (throughput, patient satisfaction, etc). I would encourage all trauma centers to examine the flow and delivery of care for major trauma patients in the ED and to attempt to streamline those processes so the patients can move on to the inpatient trauma areas or ICU as efficiently as possible.

This is my last day at Arab Health 2014 at the Dubai Convention Center. Please stop by the US Pavilion, booth 1E19 (Minnesota International Medicine) and say hi. I’ll be there today from noon to 5PM Gulf Standard Time.
CPR has increased the survival rate of patients suffering cardiac arrest, and early bystander CPR has been shown to double or triple survival. The sad truth is that CPR is not frequently performed by the general public. The American Heart Association has attempted to simplify CPR to the point that even untrained bystanders can administer chest compressions without a pulse check and without rescue breathing.
But what happens if that well-intentioned bystander starts CPR in someone who has not arrested? How often does this happen? Can the patient be injured?
The Medical College of Wisconsin reviewed the charts of all patients who received bystander CPR in Milwaukee County over a six year period. There were 672 incidents of bystander CPR. Of those cases, 77 (12%) were not in arrest when assessed by EMS personnel, and the researchers focused on those patients.
EMS response time averaged 5 minutes, and was greater than 10 minutes in only 2 cases. Average patient age was 43(!). The male/female ratio was just about 50:50, and the majority of the incidents took place in the home or residence.
Hospital records were available for further analysis in 72 of the patients. A quarter were sent home, a quarter admitted to a ward bed, and half were admitted to an ICU. Only 12 (17%) had a cardiac-related discharge diagnosis. The next most common discharge diagnoses were near-drowning, respiratory failure and drug overdose. Younger patients (<19) were usually near-drowning victims, and older patients (>54) were most commonly diagnosed with syncope. Five patients did not survive. Only one CPR injury was identified, which was charted as rhabdomyolysis “secondary to having received CPR” (a weak injury diagnosis, in my opinion).
Bottom line: The potential benefit of bystander CPR outweighs the risk of injury or performing it on a victim who is not in arrest. This study shows that, although these patients may not need CPR, they are generally very ill. Given the rapid EMS response times and the younger average age of the victims, no real injuries occurred. The new American Heart Association recommendations are beneficial and should be distributed widely.

Thanks to all the readers who stopped to say hi at Arab Health Expo 2014! I’ll be at the Minnesota International Medicine booth in the USA Pavilion again, booth #1E19 all day today and tomorrow. It’s located in Hall 1 in the Dubai International Convention and Exhibit Center next to the World Trade Center.
See you there!
Although you may not agree with this at first, communicating with our patients is one of the most important things we do as trauma professionals. You can be the “best” doctor, nurse or paramedic in the world, but if you can’t communicate well your patients will have nothing good to say about your care of them.
The most important skill needed for good communication is empathy. You need to be able to put yourself in their position. Imagine what you would want if you were on the receiving end of the information you are about to deliver. What would you say if you were talking to your spouse, your mother, or your child?
Next, think about what kinds of things they would want to know. In trauma, they obviously want to know information about the injuries. Patients and families also need to hear about the short term and long term plans. What’s going to happen in the next few hours? Will surgery be needed? When? How long will I be in the hospital? How long will I be out of work?
Many of these questions are difficult to answer at the time of admission after trauma. If you don’t know or it’s impossible to determine, say so. Experienced clinicians can make some pretty good guesses, but should always qualify their answers. You should make it clear that you are giving an estimate, and that things may very well change. Also explain that as these changes occur and time passes, you will give better estimates.
One of the most important things to remember is the “keep it simple” mandate. Our patients and their families are smart. Although they may not know the lingo that we are familiar with, they can grasp the concepts of what is happening. Be careful to keep your explanations understandable, and don’t make the mistake of using any complicated medical terms. Imagine the surprise of the patient when they find out what “we’re going to insert a Foley catheter now, sir” really means. Also keep in mind that the patients and their families are stressed, and may not be able to concentrate on or remember everything you say. Repetition is good in these situations.
Communication after major trauma is challenging. Remember, if the families don’t get what you’re saying, it’s your fault, not theirs.
