Tracking the effects of policy changes in prescribing analgesics in one emergency department: a 10-year analysis.

According to the WHO, the yearly national consumption of opioids is one indicator of a country's investment on relieving moderate-to-severe pain. We implemented guidelines for treatment of pain in our emergency department (ED) and tracked the major analgesics used in this ED to monitor trends in pain management over a decade. The study was carried out in a Level I trauma center ED. Data were obtained from the pharmacy's computerized records before (1998-2002) and after (2003-2007) implementing the guidelines. The hospital's admission system provided accurate patient census data. Parenteral morphine and oral oxycodone use increased significantly (P = 0.016 and P = 0.008, respectively). Meperidine use did not change. In conclusion, our ED patients are now generally receiving more analgesics than 10 years ago. Electronically stored data on analgesics are accurate and easily accessible for tracking the nature and quantity of prescriptions, but not for correlating their association with patient outcome.
