Introduction
In the United States, there were over 129 million Emergency
Department (ED) visits in 2010, [1] with acute pain syndromes,
including stomach pain, chest pain, musculoskeletal pain, headache,
and earache, among the leading complaints [2]. Emergency care focuses
on immediate, short-term (acute) analgesia in a hectic setting with little
opportunity for follow-up. Te pharmacological treatment of acute
pain involves balancing its potential benefts against potential harms,
but much of what is known about analgesic safety and efcacy has been
derived from studies of mid- and longer-term use [3,4]. Tere are few
guidelines that address pain management in the ED setting, although
guidelines for specifc conditions and populations exist [5-7]. In 1999,
the Joint Commission on Accreditation of Healthcare Organizations
declared pain as the “ffh vital sign” and required hospitals to make
pain control a priority [8]. For reasons unique to the ED setting, pain is
not as well managed in the ED as in the surgical setting [9].
About half of ED patients complaining of pain receive no analgesic,
and of patients reporting severe pain, 63% receive no analgesic [10]. In
a survey of 842 patients at 20 U.S. and Canadian hospitals, only 60%
of ED patients received analgesics with a median delay of 90 minutes
(range 0 to 962 minutes) and, most concerning, 74% were discharged
in moderate to severe pain [11].
Tere are multiple barriers to adequate pain control in the ED. One
is that patients may not request analgesia. In a survey, it was found that
42% of ED patients discharged without analgesics had wanted them, but
31% of that group did not specifcally request them [11]. New emphasis
on patient satisfaction may drive a change here, in that efective pain
control signifcantly improved patient satisfaction scores of ED care
(n=328) [12]. So while patients may not always ask for pain relievers,
they may want or expect them. Emergency clinicians practice in a
unique atmosphere that emphasizes triage and ofen relies on the rapid
transfer of patients to other clinical departments for more specialized
care. Te nuances of pain management can be lost in an environment
Abstract
Millions of patients are treated every year for acute pain symptoms in the Emergency Department (ED), but pain
control in this setting still remains suboptimal. This may be due to the logistical challenges in the ED, ED clinicians’
limited education and training in pain control, regulatory and legal concerns, and other barriers to prescribing. The
most common analgesics used in the ED are acetaminophen (paracetamol), Non Steroidal Anti-Infammatory Drugs
(NSAIDs), and opioids. All are effective in relieving pain, but are also associated with serious side effects. Thus, pain
control in the ED becomes a balancing act of weighing potential benefts and risks. NSAIDs are often the appropriate
choice for many of the common acute pain conditions encountered in the ED, but because of risks associated,
administration is often limited. A review of the literature regarding current ED pain treatment practices and guidelines,
patient and clinician barriers to pain treatment in the ED, and the pros and cons of current analgesic options for the
ED is warranted and timely. The objectives of the current review are to: (1) provide healthcare providers with an
overview of the current state of acute pain treatment in the emergency room setting, (2) describe the common drug
treatments utilized in emergency medicine, (3) review advantages and disadvantages of these treatments, with a focus
on NSAIDs, and (4) examine the potential value of novel “low dose” NSAID formulations for use in this setting.
that emphasizes rapid and transient care. Another barrier is clinicians’
generally inadequate training in acute pain management, reticence to
use opioids, the “ED culture,” as well as personal biases [13]. Moreover,
many clinicians in and outside the ED are rightly concerned about
potential adverse efects of analgesics and may hesitate to prescribe
potentially harmful drugs to patients they are not going to follow. Such
non-clinical factors have been shown to infuence prescribing decisions.
For example, in a study of opioid prescribing practices at a single center
before and afer the arrest of a physician for drug diversion, patients
with moderate pain were signifcantly less likely to be prescribed
an opioid immediately (<90 days) afer the arrest than before (0.4
likelihood ratio, confdence interval, 0.2 to 0.7), although prescribing
patterns for patients in mild and severe pain remained unchanged [14].
In New York state, I-STOP legislation passed in 2012 requires all
prescribers of Schedule II, III, and IV controlled substances to consult
the Prescription Monitoring Program in that state prior to prescribing
drugs [15]. Since emergency medicine ranks third among all specialties
for writing opioid prescriptions for 10-19 year olds and 20-29 years old
and ranks fourth for 30-39 year olds, [16] emergency medicine serves
a population at high risk for inappropriate opioid usen [17]. Tis may
increasingly cause emergency room clinicians to hesitate to prescribe
opiates. So common is misuse of opioids in the emergency setting that
the term “oligoanalgesia” has been used to describe the situation [18].
