Characteristics of pain in hospitalized medical patients, surgical patients, and outpatients attending a pain management centre

The characteristics of pain in the medical and surgical groups were similar, with high levels of anxiety and depression. The pain management group differed from the inpatient groups, with higher levels of psychopathology and poorer coping. These findings provide some insight into the complex nature of pain in hospital inpatients, and may inform where limited resources should be utilized to provide greatest patient benefit.
