Stop Dissing Response Times and Start Dissecting the Argument

It is not hard to find an article that bashes the industry’s insistence on measuring response time as a performance goal. The latest one I saw was published just today in “Don’t let response times overshadow the role of EMS” by the respected author Arthur Hsieh. The flow of his article follows the traditional pattern of claiming that measuring time is an outdated historical artifact of EMS without any basis in science, followed by the inevitable near-contradiction confessing that time is critical is only a limited number of cases before finishing by imploring future leaders to take a courageous stand against the uneducated politicians who simply fail to understand our modern evolving business. Hsieh is certainly not alone in making this well-worn, if not self-serving and short-sighted, argument.

Assuming my readers are familiar with the clinical EMS process of assessment, let me present a reasonable differential in terms we can hopefully appreciate. First, what bothers me in the common debate is the assumption that what we see is the totality of the problem. The ingrained reflex of our ABC mnemonic is only for the initial impression, not the final diagnosis. We must resist the urge to simply treat the surface presenting problem and investigate even deeper for an underlying pathophysiology. Our assessment should probe whether the response time concept itself is really the source of the disease, or is it possibly the uncomfortable idea of a formulaic approach to system “compliance” underlying the measure that makes us protest so loudly? Are we taking our frustrations of prescribed protocols out on one single measure when it is actually any measure that attempts to pit arithmetic against our artistic judgement and the free expression of our healing knowledge? Another idea of an underlying cause may be that we equate good response times with unsafe speeds or the very real growing risk of ambulance-involved collisions from excessive speeds and increasingly inattentive drivers. Or could it be a frustration, often expressed as “running hot to a stubbed toe,” that suggests we are simply expending extraordinary efforts on the wrong cases altogether because current EMD processes are not adequately refined in order to triage our limited response options to the unworthy types of calls we are seeing lately?

Without exception, everyone that brings this topic up recognizes at some point that there are clearly instances where time is actually critical. STEMI, stroke, and anaphylaxis are usually among the list of obligatory concessions. Still, we seem way too willing to just “throw the baby out with the bathwater.” In the fire service, there is a well-known motto that says, “train like you fight, fight like you train.” To me, that translates to always practicing the things that are important even if it doesn’t make a difference every single time. There are often instances when (whatever “it” is) genuinely saves a life (whether your own or that of a patient). Sometimes, the “it” is time. There may not be any magic in “10 minutes” (or whatever your standard may be) or even the “golden hour” itself, but there is inevitably an “expiration” on our efforts. There is a time limit when the value of all our interventions diminish to the point that they can no longer buy back the life of our patient. A short response time gives us more time to consider options. It is no longer a question of “stay and play” versus “load and go”, but always to “think and act.” The anxiety of our patients and their family or friends at the scene are measurably lowered by our professional presence. If that is not your experience, then you may actually be correct in believing that your response time truly does not matter.

Just as we do our assessments, we can’t stop at the first symptom of a problem and treat it in isolation. We must often dig deeper to understand an underlying cause that needs to be treated more importantly than just the first observed sign of it. Hsieh is correct in saying that “It’s really time to move on and get with the times,” but  not by neglecting the value of our response, rather in addressing the underlying objection to having it measured. Politicians are never likely to admit to understanding our disagreement to measuring response times because they do not account themselves to us, but to the public that demands our prompt service that keeps them in office. If we insist on expending energy to attempt change, direct that energy in the most productive way it can be used. This begins by recognizing the root problem and the limitations of our interventions to affect change in it.
