The effect of education, assessment and a standardised prescription on postoperative pain management The value of clinical audit in the establishment of acute pain services

A study involving 2738 patients in 15 hospitals in the United Kingdom was undertaken to evaluate the effect of simple methods of pain assessment and management on postoperative pain. The study consisted of four parts: a survey of current practice in each hospital; a programme of education for staff and patients regarding pain and its management; the introduction of formal assessment and recording of pain and the use of a simple algorithm to allow more flexible, yet safe, provision of intermittent intramuscular opioid analgesia; and a repeat survey of practice. One hospital from each of the former health regions of England and Wales was selected for inclusion in the project. Hospitals included representatives of different size units (university, large and small district general hospitals). As a result of the study, there was an overall reduction in the percentage of patients who experienced moderate to severe pain at rest from 32% to 12%. The incidence of severe pain on movement decreased from 37% to 13% and moderate to severe pain on deep inspiration from 41% to 22%. Similar decreases were seen in the incidence of nausea and vomiting. There was also a slight reduction in the incidence of postoperative complications. This study shows that simple techniques for the management of postoperative pain are effective in reducing the incidence of pain both at rest and during movement and should form part of any acute pain management strategy.
