Triage & Initial Treatment at the Active Shooter incident: Do you SALT your MCI?

Triage of any MCI is one of those infrequently practiced skills that have massive implications for patient outcomes, and when it’s done “wrong” it leads to wasted resources and potentially deaths.  It also has virtually no science to back it up. It wasn’t until recently that we even recognized the gap between what we knew and what we assumed about MCI Triage.  

In fact, current ALTS-based physician-directed triage training doesn’t seem to make a difference in triage outcomes!

In 2008 this gap was acknowledged, and a “new” method of triage was developed based on the limited information available and compliant with the American College of Surgeons best-practices guidelines.   This new method, using the mnemonic SALT, takes into account (in fact, relies on) developments in tactical medical care such as the modern tourniquet, almost universal NPA use, specific antidotes for chemical agent exposure.  It also allows for genuine clinical acumen and incorporates resource availability into final decision making.

More importantly, SALT is far more compatible with Hartford Consensus III which sums up the recommended response to the active shooter with the acronym THREAT:

Threat suppression
Hemorrhage Control
Rapid Evacuation from the hot zone
Assessment by medical providers
Transport to care

In an active shooter situation the first people through the door are there for job 1, threat suppression and mitigation, and this frequently (28.1%) results in an exchange of fire between the perpetrator and the responding members. Where officers engaged the perpetrator, in 46% of the events an officer was injured or killed.

But once the threat has been suppressed it’s time for the rest of the THREAT mnemonic to kick in, and that’s where SALT can play a role.

SALT stands for Sort, Assess, Life Saving Treatment, Transport.

Sorting is conducted as a “Walk, wave, still” where the the walking are directed to a safe area (to be cleared by LEO in an active shooter) unmoving are assessed first, and the waving are checked after the unmoving.

Tac Responder KitThe SALT Assessment is conducted concurrently with limited treatment, and is even simpler than START. Obvious life-threatening injuries get treated! Tourniqueting major bleeds, opening airways with positioning, NPA or ESA, decompress tension pneumothorax (and seal obvious open pneumothorax) and administer 2PAM or other antidote as required are all reasonable and appropriate, depending on resources available.

In the Tactical Medical world, this limited treatment is what’s run out of the medic’s leg bag. The jump kit doesn’t get opened outside the casualty collection point (CCP) until the treatment areas are being established.

Simple SALT Algorithm

 

The critical difference between the Active Shooter MCI and the other MCI is the speed with which providers must act.  An Active Shooter is frequently an ongoing, open incident that will continue until the shooter is contained, killed, or surrenders.  The initial RTF medics must continue to push forward with the security element, providing appropriate hemcon and other interventions with the equipment on hand and leaving follow on personnel the job of further treatment and evacuation to the cold zone.

Consider adding some SALT to your MCI!  Simple, limited life-saving interventions performed at point of injury are the norm in tactical medicine, reducing the cognitive load is essential in performing at our finest. Add these life-saving steps to your Active Shooter and MCI training!

How have we gotten here?

65% of US States lacked specific guidelines on how and when to use a tourniquet!

Blow Out Kit for HemCon

Blow Out Kit for HemCon

After almost a decade and a half of continuous warfare, after achieving the best trauma outcomes in the history of medicine, after the formation of both the Committee for Tactical Emergency Casualty Care  and the Committee on Tactical Combat Casualty Care, even when the most recent best practices are available free online, we still can’t come up with a coherent extremity hemorrhage control strategy!

Ladies and gentlemen, the evidence is there, most of the tools are there, and the techniques are well developed;  There is no longer any excuse for any patient in prehospital care to die from exsanguinating extremity hemorrhage.

Know how to use a tourniquet! Put them on your ambulances, on your belt, in your pockets.  Have a primary, an alternate, a contingency, and know how to make a emergency tourniquet one.

See our post here for the evidence supporting their use.

 

What do we owe our patients?

No, not like that, although we’ve all encountered patients or other members of society with a, shall we say, heightened sense of entitlement.  But what is our duty of care as prehospital professionals?  When can we leave a patient and when must we stay with them to definitive care?

Duty to Act

There isn’t a huge amount of information available in Canadian law that applies to this subject with regards to Paramedics and other prehospital providers, but there are some basic principles at play and some guidance from some EMS authors, the BC EMA Licensing Board and the Royal College of Physicians and Surgeons of Canada. The Royal College outlines four fundamental obligations of a physician to their patient:

  • The obligation to obtain informed consent.
  • The obligation to provide prudent and diligent care.
  • The obligation not to abandon the patient.
  • The obligation to preserve confidentiality.

While Paramedics and other prehospital providers are not bound by regulations of the Royal College, it seems prudent and reasonable to look to our physician’s guiding documents, and note that there is absolute overlap between the duties of physicians and the duties of paramedics in the other three areas mentioned. The Emergency Licensing Board of British Columbia Schedule 3 Code of Ethics writes, in part:

(a) consider, above all, the well-being of the patient in the exercise of their duties and responsibilities;

(c) protect and maintain the patient’s safety and dignity, regardless of the patient’s race, colour, ancestry, place of origin, religion, marital status, family status, physical or mental disability, sex or sexual orientation;

(d) preserve the confidence of patient information consistent with the duty to act at all times for the patient’s well-being;

(g) carry out professional responsibilities with integrity and in accordance with the highest standards of professional competence;

One key question that must be answered if any fault is to be found is “Did the Paramedic have a duty to act?”  In the prehospital setting, it is reasonable to say that a Paramedic or other public safety member who is responding in a professional capacity to a call for service, whether this comes from a flag-down on the street or a 911 call, has an established duty to act in the best interests of the calling party (if they and the patient are the same individual), or, with consent, any person found in medical distress at the location.

What is abandonment?

Nancy Caroline, the author of Emergency Care in the Streets very succinctly wrote “Abandonment can occur anytime Paramedics turn over their patients inappropriately or to a level of care lesser than themselves or if they leave a patient without ensuring the patient had the mental capacity to refuse treatment or transport.”

If you have established a relationship with a patient, by assessing, treating, or otherwise offering aid to a person in distress, and then you leave them without handing them off to a person capable of providing care to an equal or higher level you have abandoned your patient. You have breached your duty of care to that person, and can be held liable.

In the EMALB code of ethics, (c) protect and maintain the patient’s safety, would imply that Paramedics must protect the patient against reasonably foreseeable complications and risks.  While untested, this could include occult injuries at a MVC scene or the resuscitated narcotic overdose patient refusing care.

“In other words, after care of any kind is administered, the physician must “provide the medical follow-up required by the patient’s condition” unless the physician has ensured that a colleague or another competent professional will do so.36 Where a physician wishes to refer the patient to a colleague, he/she remains responsible for the patient until the new physician takes up the patient’s care.37″

Big Box vs Small Box EMS Education

I’ve been working on this post for a couple of weeks, and then along comes LUTL and Chris Kaiser who posts on pretty much the same topic, and does a better job of it, but I’m going to post it anyway. Here’s a link to Chris Kaiser’s article.

I was off for almost two months with a bum shoulder, and my inner EMS geek came out in full force.  I’d been following the Social Media and Critical Care Conference (SMACCUS) online for a couple of days, and it was both a positive and negative experience.  On the on one hand, it became completely apparent to me that we’re not providing the most cutting edge care that we can. On the other hand, it’s easier than ever for Paramedics around the world to provide that cutting edge evidence based medicine. Sea Can

 

Among my peers, there are two competing theories of EMS education, what my partner and I refer to as the “small box vs big box debate”.  The small box theory of EMS is the system that many of us come from.  In order to be a PCP I need to know how to perform the following procedures….I need to know the indications, contraindications, dosages and routes for the following medications…I need to know how to recognize, diagnose, test for, and treat the following conditions… And the reason we think that way is that’s the system that we come from, that’s the way EMS programs are designed, especially in light of Canada’s NOCPs. Crich

The big box theory states that I need to know all that, and lots more.  I’m a better paramedic who delivers more effectively treated patients to the hospital because I also know about things OUTSIDE my scope of practice.  I read up on ECMO, ROTEM, REBOA, blood products, rehab, and indications for procedures I can’t perform. Why? Because prehospital and retrieval medicine needs to be a team sport, and I can best support my ALS colleagues, the nursing team and Emergency Physician in the ED, the Trauma Surgeon in the MTC, the RTs and allied health care providers if I can anticipate their needs.  In the past two weeks I’ve approached my ALS colleagues with some neat things that I’ve seen thanks to @Ketaminh on Twitter, and in both cases they’ve been positively received.  An ETT setup that allows you to suction through the tube during VL or DL? Awesome!  A new use for the venerable Stiffneck? Hilarious, but great.

20150718_213034Let’s look at a “simple” skill, common across the full spectrum of practitioner levels: As the Paramedic Association of Canada describes it “Perform ventilation using a manual positive pressure device” which means everyone from First Responder and Occupational First Aid to EMR to CCP needs to know how to use a manual resuscitator (BVM) to assist or provide breaths to a patient. We all need to know it because we may all need to do it. We teach all sorts of people how to do it.  Poorly.  And we KNOW that using it poorly is potentially devastating to all sorts of patients!  Life-saving, yes.  Benign, no.

I’d been in EMS for almost a decade before an anesthesiologist showed me how to use a BVM properly, who took the time to explain what it was doing behind the scenes, on a physiologic basis.  It’s been over a decade since then, and despite the trickle-down effect of knowledge translation, it’s still a tool that’s used improperly by many Paramedics.  Paramedics with months in the classroom and hundreds of hours in practice still use it improperly, because the foundation their practice is built on is less than solid.

In his book Outliers Malcolm Gladwell says that expertise takes 10,000 hours. I was let loose on patients with 10 minutes of actual instruction and less than 10 hours of practicing bad habits, and it took me almost 10 years to realize it. Now I’m happy to say that AIME is one of the four-letter-acronym courses that I help deliver for BCEHS Learning, to every BC Ambulance Service Paramedic.  We talk about endotracheal intubation to people who don’t do it because it makes them better assistants. We show extraglottic airway placement to people who don’t place them because it makes them better assistants and helps them make that “call for help” decision.  In ITLS, our CME trauma course, we discuss and demo intraosseus infusion and needle decompression to people who don’t do it because it makes them better assistants.Facepump!

Our BLS crews are being dragged into the “big box” world, which is a relief for those who have been working in that larger medical world as their practice. We’ve moved from protocols to Treatment Guidelines, and our prehospital practitioners are free to pursue treatment goals versus applying treatment protocols.

CPAP in ClassThis puts a huge amount of responsibility onto the individual Paramedics, and none more so than the Primary Care Paramedics who staff the bulk of ambulances across British Columbia.  Over the past several years we’ve seen major leaps in PCP practice in BC.  We’ve added TXA, EGA, CPAP, PEEP, NPA, NODESAT and dimenhydrinate. We’ve added a pediatrics module to AIME, ITLS, and Cardiac Arrest Management to complete our ongoing “4-pillars” 20150726_192314training regime.  Our crews in the Lower Mainland are involved in the FRONTIER study.  The ROC TXA in TBI trial starts soon. An MCI update is in the works.  The scope of practice is advancing, and the knowledge base required to differentiate, to diagnose, to treat our patients is deeper than ever before.

There is a movement to bring “upstairs care downstairs,” to bring ICU level care to the Emergency Departments of the world.  As this movement gains momentum, Paramedics need to be prepared to bring that same level of care to the prehospital setting.  The key to doing this is to take a “big box” view of EMS education from the moment we set foot in the classroom, commit to career-long learning, and be prepared to up our game continuously.
