Patients with traumatic brain injury (TBI) and their families rely on health care providers, particularly nurses, to provide accurate information, yet inaccurate beliefs about TBI have been found among nurses. Although prior studies have assessed nurses' beliefs about TBI recovery and rehabilitation, none have assessed specific beliefs about the nursing role to care for these patients. The purpose of this study was to investigate nurses' beliefs and learning preferences about caring for patients with moderate-to-severe TBI. A cross-sectional survey was administered to 513 nurses at a Midwestern hospital between October and December 2014 (20.3% response rate). Latent class analysis was used. Findings showed that nurses had inaccurate beliefs about TBI relating to recovery and the nursing role, and had significant differences in learning preferences. These findings have implications for development of educational and training interventions specific to nurses to ensure that they have factual information about TBI and to clarify the nursing role.
