Perceived control mediates the relationship between pain severity and patient satisfaction

The factors that account for patient satisfaction with acute pain management remain a mystery. Consistently, there has been an inverse, but very small association between pain severity and patient satisfaction; most patients are in severe pain, yet report they are satisfied with pain management. The hypothesis that perceived control mediates the relationship between pain severity and patient satisfaction was examined in 137 patients who underwent elective inpatient orthopedic surgery. Postoperatively, patients rated their pain severity (the highest level of pain experienced), their perceptions of control over the pain and taking pain medication, and their satisfaction with the relief they obtained from analgesics. Path analysis using LISREL was used to test for mediation. Pain severity was associated inversely with perceptions of control over pain and with satisfaction. There was a significant association between perceived control and satisfaction and perceived control partially mediated the relationship between pain severity and satisfaction. Although individuals who report experiencing severe pain are less satisfied with pain relief than individuals with less pain, it is the interpretation or perception of having control over the pain that most relates to satisfaction with pain relief. Clinically, it is important to examine ways in which individuals control their pain, teach them methods to exert control, and educate them that it is preferable to not allow pain to become severe--it is easier to "control" pain if you intervene at an early point.
