Is It A Trauma Center Or A Coffee Shop?

Tim Horton’s is a large franchise operation that runs about 3,750 coffee shops / restaurants in the US and Canada. Some of these franchises are located inside other establishments, such as hospitals. The outlet in the Royal Columbian Hospital in New Westminster, British Columbia, Canada is one such location, and it did double duty last month. Royal Columbian is the region’s trauma centre.

Due to a large number of patients being treated in the ED and some fly-ins from earlier in the day, the coffee shop was cleaned and converted to overflow for patient care. Six stretchers with privacy screens were set up and four patients were treated in the area. This situation lasted for about 90 minutes until the overcrowding eased. The shop was cleaned once again and ready to open normally the next morning, serving coffee, not patients.

Myth: Motorcycle Helmets and Cervical Spine Injury

March 25, 2011 The Trauma Pro Leave a comment

The number of motorcyclists has been increasing over the past decade. At the same time, the number of states repealing their helmet laws is increasing. The evidence is convincing that the number and severity of brain injuries is decreased with helmet use. But what about spine injury?

Many arguments against wearing helmets given by riders are derived from a report in 1986 by Goldstein*. One of the issues cited in this paper is the potential increase in cervical spine injuries due to the weight of the helmet. A recently published study using the National Trauma Data Bank (NTDB) corroborates several smaller studies which show that this just isn’t so.

All motorcycle collisions in the NTDB involving adults were analyzed by logistic regression. Missing data was compensated for using standard statistical techniques. Nearly 41,000 cases had complete records for analysis. About 77% of riders were wearing helmets, and the overall mortality was 4%.

Nonhelmeted riders suffered the following statistically significant differences:

A higher proportion of severe head injury (19% vs 9% with helmets)
Higher incidence of shock on admission (6% vs 5% with helmets)
Higher injury severity score (ISS) (14.7 vs 13.4 with helmets)
Higher crude mortality (6.2% vs 3.5% with helmets)
Higher incidence of cervical spine injury (5.4% vs 3.5% with helmets)

Bottom line: Motorcyclists wearing helmets had a 22% reduction in the likelihood they would sustain a cervical spine injury in a crash. This is in addition to decreases in shock, injury severity and death. These data need to be considered when the future of helmet laws is considered in any state looking at repealing them.

What Is The Cribari Grid?

What Is The Cribari Grid?

I’ve spent some time discussing undertriage and overtriage. I frequently get questions on the “Cribari grid” or “Cribari method” for calculating these numbers. Dr. Cribari is currently the chair of the Verification Review Subcommittee of the ACS Committee on Trauma. He developed a table-format grid that simplifies calculation of these numbers.

I’ve simplified the process even more and provided a Word document that automates the task for you. Just fill in four numbers in the table, update the formulas and voila, you’ve got your numbers! Instructions for manual calculation are also included.

Trauma 20 Years Ago: ED Intubation For Head Injury Is Safe

March 22, 2011 The Trauma Pro Leave a comment

How far we have come! It’s now commonplace to intubate trauma patients in the ED using rapid sequence induction followed by orotracheal tube placement. However, 20 years ago we were still gnashing our teeth about safety.

In 1991, the group at UMDNJ Newark looked at 100 consecutive trauma patients with suspected head injury who were paralyzed and intubated in the ED. Half of the intubations were performed by a surgeon, the other half by an anesthesiologist. Fifty seven patients were intubated orally and 40 nasally(!). Three required cricothyroidotomy after failure to intubate due to facial fractures.

The majority of these patients had head scans performed; 59% were positive and 15 required emergent neurosurgical procedures. No patients were found to have a neurologic deficit from the intubation even though seven were eventually found to have cervical spine injuries. Only one patient developed an aspiration pneumonia.

The authors concluded that paralysis and intubation in the ED was safe. It helped facilitate the diagnostic workup because they could control combative patients. Up to that time, the only alternative was heavy sedation, which carried its own risks.

Interesting points on how far we have advanced:

Intubation in the ED did not used to be routine. There was a great deal of anxiety before this procedure
Nasal intubation was still fairly commonplace
The cricothyroidotomy rate was high
Intubation was usually performed by a surgeon or anesthesiologist

Need CPR? There’s An App For That!

The San Ramon Valley Fire Protection District has released an iPhone app that gives users a window into their 911 dispatch center. When you install the app, you can indicate that you are trained in CPR. Your phone then provides your GPS location, and you can be notified of any sudden cardiac arrest events in your area. You can then proceed to the incident and render assistance, if appropriate.

App users can view all active incidents and the status of dispatched units. If an ambulance passes you or you are stuck in a traffic jam, just tap the screen to find out the details. They can also be notified of incidents by type, and monitor live emergency radio traffic.

The only downside is that leaving GPS location apps active in the background can significantly shorten your battery life. I think we can expect more communities to begin offering services like this in the near future.
