Registered nurses (n = 72) working in 10 paediatric units in community hospitals in north-eastern Ontario, Canada, participated in a descriptive study investigating how nurses assess and manage pain in children. A four-part questionnaire was used to collect the self-reported data. Twenty-five (36%) of the respondents defined pain as an individual and personal experience and another 25 (36%) respondents defined pain as a more or less localized sensation or discomfort resulting from the stimulation of specialized nerve endings. In response to three different clinical situations, the subjects' mean pain ratings were: 5.72 for an infant; 7.34 for a 3-year-old; and 7.29 for a 12-year-old child. The criterion 'nurses' judgment' was cited as being used frequently in both the assessment and decision making process; however, there was indication that some of the current knowledge in the assessment and management of pain in children was not known or being used.
