Increasing attention is currently being directed to the measurement and treatment of pain. A recent study concluded that the implementation of a patient safety programme was successful because 99% of the hospitals indicated that they measure postoperative pain. However, another recent study, evaluating this safety programme, concluded that hospitals could improve the implementation of pain measurements, as only 56% of the postoperative patients were subject to standardized pain measurements during the first 3 days following surgery. The reason for this notable difference may be the tendency to implement pain registration mainly for external justification purposes. The attitude towards pain needs to change; too often it is still considered as an uninteresting side effect of treatment. Insight in the internal utility and effects of pain registration might help to further improve the quality of postoperative pain management. Acute Pain Service teams should have a facilitating role.
