Anaesthesiologist-associated risk factors for inadequate postoperative pain management

SummaryBackgroundIssues associated with the analgesic failure are major contributors to diminished postoperative health quality. The aim of this survey was to investigate the risk factors associated with anaesthesiologists for inadequate postoperative pain management, i.e. ≥3 cm in a 10 cm gauge of Visual Analog Scale.MethodsA total of 1162 confidential questionnaires were sent by mail to anaesthesiologists in clinical hospitals. Information was queried on the incidence of inadequate postoperative pain management with different length of experience in anaesthesia, reasons for such incidence and possible rescue treatments after the occurrence of the incidence, and knowledge in terms of analgesia protocols. Education background and working settings were requested as the contributing factors.ResultsIn 813 returned questionnaires, 798 were completed and the data were valid for analysis (68.7% valid response rate). Approximately 43% reported encountered at least one or more incidents of inadequate postoperative analgesia. All positive answers indicated inadequate postoperative analgesia was related to types of surgery. A multiple logistic regression (r2 = 0.74, P < 0.0001) analysis revealed that age, length of anaesthesia experience, education background and work environment are four risk factors in contributing to the incidence. Patient-controlled analgesia is the first choice for postoperative pain therapy, and opioids are preferred as the rescue drugs for inadequate postoperative analgesia.ConclusionsInadequate postoperative analgesia occurs widely. Age, length of anaesthesia experience, education background and the working environment of anaesthesiologists are risk factors for inadequate postoperative pain control.
