Changing patterns in the acute pain service: epidural versus patient-controlled analgesia

This study involved an audit and a survey of the Acute Pain Service at Princess Alexandra Hospital. It was found in the audit that the relative choice of epidural analgesia had declined by 50% over the five-year time period of 1998-2003. The survey of consultants showed that 82% of them had changed their practice and that they were performing fewer epidural anaesthetics. Two of the most common reasons given for this change in practice related to fear of litigation (34%) and lack of evidence (21%). These results show that within this department approaches to postoperative pain control had changed and that this appears to have resulted from factors such as the medicolegal environment and the possible influence of evidence based medicine.
