Behavioral Pain Scale and Critical Care Pain Observation Tool for pain evaluation in orotracheally tubed critical patients. A systematic review of the literature

Abstract

Objective:To describe the appropriateness of two behavioral scales, the Behavioral Pain Scale and the Critical Care Pain Observation Tool, for pain assessment in orotracheally intubated patients admitted to intensive care units.Method:Using the methodology recommended by the Cochrane Center, a systematic literature review was performed in the electronic database EBSCO Host (CINAHL Complete; MEDLINE® Complete; Nursing & Allied Health Collection: Comprehensive; Cochrane Central Register of Controlled Trials; Cochrane Database of Systematic Reviews; Cochrane Methodology Register; Library, Information Science & Technology s; MedicLatina). Two searches were conducted using the following English terms in the search field: “behavioral pain scale” AND “critical care pain observation tool” AND “behavioral pain scale” OR “critical care pain observation tool”. Two independent reviewers performed the critical evaluation and data extraction and synthesis.Results:Fifteen studies were included that showed that the Behavioral Pain Scale and the Critical Care Pain Observation Tool are valid and reliable scales for pain assessment in orotracheally intubated patients admitted to the intensive care unit. The scales showed similar psychometric properties and good reliability.Conclusion:Both scales are adequate for assessing pain in orotracheally intubated patients admitted to intensive care units; however, they exhibit limitations in specific populations, such as trauma, burn and neurosurgical patients. Further studies on the subject and in specific populations are suggested.
