In early 2022, 14 international EMS, patient safety, quality and fire associations published a joint position statement To advertise EMS methods to cut back the incidence of sunshine and siren (L&S) automobile operations. This represents vital alignment by these associations on the dangers and advantages of L&S EMS automobile operations.

Most EMS clinicians who’ve responded to various EMS calls be taught from a medical want perspective that there are occasions when an L&S response can and infrequently can’t be assured. L&S response will increase the chance of an EMS automobile accident by 50% and virtually triples the chance of an accident throughout affected person transport [1]. However how ought to companies undertake the trouble to vary the 50-year tradition inside each emergency companies and their communities to cut back L&S automobile operations?

Perhaps you can debunk these common myths about lights and sirens and begin processes that will help make your organization's staff and your community a little safer.

There are a lot of myths surrounding L&S automobile operations that we have to dispel. Maybe you’ll be able to debunk these widespread myths and start processes that can assist make your group’s workers and your group slightly safer.


On a regular basis, the controversy in regards to the suitability of lights and siren automobile operations, “the general public expects us to reply their name to L&S; If we do not, they’re going to assume we’re not taking their medical emergency critically.” Are you positive? Did we actually ask them that? Do they actually care?

A 2017 report commissioned by NHTSA consists of references to 2 surveys during which respondents had been particularly requested about their expectations of L&S responses.

In 1988, a public phone survey in Connecticut cited sirens and noise as the first explanation for annoyance to name EMS in an emergency, and this response was adopted by “getting an excessive amount of consideration”. [2].

In 2005, the Anne Arundel County, Maryland system deliberate to extend their response and delivery with out utilizing L&S. They surveyed the group and located that 85% of the inhabitants surveyed had been happy with the non-L&S response based mostly on dispatcher screening and non-L&S transportation after EMS supplier evaluation. [3].

The variety of occasions callers requested “no lights or sirens” from a 911 attendant signifies that many individuals don’t want L&S consideration, even in an emergency. If there’s a basic expectation for L&S response on all calls, it is probably we (EMS methods) given This expectation of the general public, so we might be accountable altering this expectation.

Dispel this delusion: Begin with a group notion survey, together with a centered survey for elected and appointed officers, just like the one performed in Connecticut and Maryland. The consequence could shock you. After all, the survey could be extra correct when you first educate the authorities and the group in regards to the risks of EMS automobile accidents and the true time gained by L&S response.


One of many first research to guage the affect of L&S operations on delivery occasions was accomplished by Hunt in 1995. [4]. The examine discovered a mean discount of 43.5 seconds when utilizing L&S.

This 2017 NHTSA report The L&S response recognized 15 research that in contrast time saved throughout delivery or each. Common time financial savings had been 2.5 minutes for responses and a couple of.4 minutes for transfers. A lot of the authors of those research prompt that solely a small subset of sufferers would profit from the time recorded.

Superior 911 name facilities that do an efficient job of offering emergency medical referral (EMD) can successfully categorize EMS requests based mostly on their response precedence, working with a doctor medical director. A 5-year-old affected person who choked whereas consuming a sizzling canine that appeared to have a whole airway obstruction ought to have a distinct EMS response than a 21-year-old affected person with an ankle harm. The previous could also be appropriate for an L&S EMS response (plus a response from the closest police officer and hearth/rescue unit or perhaps a CPR skilled public works employee), whereas for the latter a non-L&S response by an ambulance is just acceptable.

Dispel this delusion: use your company’s information cross-reference the affected person’s medical presentation with EMD response precedence upon arrival of EMS. Alter your danger tolerance for issues like the proportion of sufferers with unstable important indicators, the speed of want for essential ALS interventions or hospital-appropriate L&S transplants. This could be a strong evaluation to find out which EMD markers are secure for a non-L&S response. You possibly can see that this may considerably scale back L&S responses and collision danger.

Equally, in comparison with the necessity for L&S response, only a few EMS sufferers have the situations to enhance outcomes by saving a couple of minutes to reach at hospital sooner. EMS clinicians can meet the wants of virtually all sufferers throughout transport to the hospital, and a peaceful consciousness offers a extra calming {and professional} setting for our sufferers than a busy L&S journey.

The good thing about L&S doesn’t outweigh the danger of an L&S transplant if hospital workers don’t instantly carry out a life-saving process after we arrive.

Fortuitously, many EMS company studies (and the Nationwide EMS Data System [NEMSIS] information present) The incidence of L&S carryovers is way decrease than L&S responses. Nonetheless, as said within the joint opinions of 14 associations, carrying L&S can also be harmful and 100% quality assurance Evaluate to find out whether or not the two.4 minutes saved by bringing the L&S to the hospital is well worth the medical advantage of exposing the affected person, workforce and the general public to a few occasions the danger of ambulance accident.

A notice about STEMI sufferers: There may be a lot dialogue in some circles about L&S transplants for STEMI sufferers. One camp considers the common time financial savings of two.4 minutes to be well worth the danger, whereas others recommend {that a} STEMI affected person shouldn’t be uncovered to the L&S setting, which will increase coronary heart fee, blood strain, and myocardial oxygen demand. This could be a superb matter to debate with the EMS company medical director.


Let’s face it, driving with L&S enjoyable! Nonetheless, don’t trigger crashes and accidents. immortality enjoyable. An ambulance accident additionally excludes two extra ambulances (concerned and at present responding to the accident) from the EMS response system, lots of that are already stressed by staff shortages and increased workloads. This doesn’t assist in getting a well timed response to the unique EMS name.

In preparation for a top quality assurance challenge with the Nationwide EMS High quality Alliance (NEMSQA), MedStar obtained 20 weeks of information from our affected person care reporting system. The information extraction included each information imported from the cargo and information fields entered by the crew. We had been slightly shocked to see that so many responses had been recognized. dispatch as the realm shipped L&S, nevertheless, entered the crew’s non-L&S response.

We initially thought this could be a knowledge anomaly, till we began asking our area clinicians about it. Many area suppliers instructed us that sure, they normally reply non-L&S even when referred in L&S circumstances. When requested why, we had been typically instructed that L&S responses had been harmful, did not save a lot time, and had been typically not well worth the danger.

Listening to loss has been present in EMS clinicians from city environments when uncovered to extreme siren noise, and L&S driving is commonly accompanied by onerous stops and turns, which can lead to unstable falls and accidents to unbridled clinicians within the affected person compartment. Anecdotally, some EMS clinicians from companies that routinely use non-L&S responses on many 911 calls discover they arrive on the name with much less stress and a burst of adrenaline and might present extra calming affected person care.

Dispel this delusion: Discuss to your EMS clinicians. Ask them what they consider L&S. Additionally, bear in mind the aforementioned survey for the group, elected and appointed officers? A survey asking your area clinicians about their perceptions, expectations, and wishes concerning L&S automobile operations and the way most of the 911 sufferers or calls are actual emergencies could reveal {that a} tradition shift to cut back L&S automobile operations could already be nicely underway. path. You could need to repeat the survey after you’ve gotten been educated in regards to the danger of L&S collisions and the proof of time gained through the use of L&S.
