title: Patterns and clinical correlates of pain among brain injury patients in critical care assessed with the critical care pain observation tool.
abstract: This study was conducted to assess the patterns and clinical correlates of acute pain in brain injury patients during the critical care period using the Critical Care Pain Observation Tool (CPOT). Data were collected from 31 brain-injury patients admitted to an intensive care unit (ICU) at a university hospital located in Incheon, Republic of Korea. Glasgow Coma Scale and CPOT scores were assessed on days 1, 3, 6, 9, and 14 after ICU admission. Results showed that temporal changes in pain intensity displayed a consistent pattern in critical care patients with a brain injury during the first 14 days of ICU admission. Mean pain score was highest on day 1, decreased rapidly to reach a minimum on day 3 or 6, and then increased on day 9. In most patients, pain reduced slightly on day 14. Mean CPOT scores were significantly higher in the nonsurgery group than in the surgery group. There was also a nonsignificant trend of higher pain intensity scores among patients with moderate brain injury compared with those with severe injury. CPOT scores immediately after endotracheal suctioning were significantly higher than before endotracheal suctioning, but CPOT scores 20 minutes after suctioning were similar to those before suctioning. The present study may be meaningful in terms of presenting valid clinical information regarding the patterns and characteristics of acute pain in brain injury patients who are often unable to self-report on the presence and intensity of pain.
