Postoperative pain management (POPM) should be based on an organization exploiting existing expertise and documenting the outcome of the POPM in each individual patient. The aims of the present study were to evaluate the adequacy of database documentation of POPM of an anesthesia organized, nurse-based, anesthesiologist-supervised acute pain service (APS) on surgical wards and to assess to what extent the information obtained was continuously used to improve practice. From 2890 registered cases in the database (patient controlled analgesia, n = 1975; epidural analgesia [EDA], n = 915), a homogeneous two-year sample of documentation charts from use of EDA for POPM in connection with major, open, abdominal surgical procedures (n = 381) was chosen for detailed analysis. The data charts contained information on patient data, drug dosage, total amount of infused drug, duration of EDA treatment, occurrence of side effects, and patient's level of satisfaction. The database information was easily accessible making assessment of relevant aspects of the routines, including associations between analgesic technique, patient related factors, and satisfaction with the services, immediately available. Only 58% of the data charts were properly completed and fed into the database but the clinical safety of the missing nondatabase documented sample was not found jeopardized. Although the database documentation routines were considered to fulfill basic requirements of data collection and monitoring of the appropriateness of POPM, they were not found to function optimally. The reason seemed to be inadequate feedback of information between the parties involved in the POPM services. The present study stresses the importance of establishing routines for adequate, continuous feedback of recorded audit data from the APS team to the surgical wards for the maintenance of a high level of compliance with accepted guidelines.
