


Assess pain characteristics and pain-related
functional interference

schedule does not relieve pain?
How clear were the instructions about how to change the
amount and timing of the pain medication if the current
schedule produces side effects?
How clear were the instructions about whom to call about your
pain if you have any questions?

Conclusions








Pain intensity is high in ED and after discharge
Analgesics are delayed
Follow-up pain assessments uncommon
IM routes used in a high proportion of cases
Deficiencies in communication and d/c
Many have chronic pain - high rates of ED use
Significant proportions with pain experience
persistent pain-related functional interference
Much remains to be done

ACEP Pain Policy - 2004





ED patients should receive expeditious pain management,
avoiding delays such as those related to diagnostic testing or
consultation.
Hospitals should develop unique strategies that will optimize ED
patient pain management using both narcotic and nonnarcotic
medications.
ED policies and procedures should support the safe utilization
and prescription writing of pain medications in the ED.
Effective physician and patient educational strategies should be
developed regarding pain management, including the use of pain
therapy adjuncts and how to minimize pain after disposition
from the ED.
Ongoing research in the area of ED patient pain management
should be conducted.
