BackgroundTelephone nursing involves triage, advice, and care management provided by a nurse over the telephone. The telephone nursing dialogue process has been used clinically in telephone nursing in Sweden for several years to structure the communication and ensure a safe assessment and advice. Studies are needed to determine whether there is sufficient scientific evidence to support the method.AimTo describe the scientific basis of the phases of the telephone nursing dialogue process.DesignThis was an integrative review.MethodsThe literature searches were performed in August 2023, in the PubMed, CINAHL, Cochrane Database of Systematic Reviews and SwePUB databases. Sixty-two articles were included. Data was sorted deductively according to the five phases of the telephone nursing dialogue process and categorized inductively to form subcategories describing the content of each phase.ResultAll five phases in the telephone nursing dialogue process were supported by a range of articles (n = 32–50): Opening (n = 32), Listening (n = 45), Analysing (n = 50), Motivating (n = 48), and Ending (n = 35). During the opening of the call, the nurse presents herself, welcomes the caller and establishes a caring relationship. In the listening phase, the nurse invites the caller to tell their story, listens actively and confirms understanding. During the analyzing phase, the nurse gathers, assesses, and verifies information. In the motivating phase, the nurse reaches a final assessment, informs the caller, gives advice and creates a mutual agreement and understanding while supporting the caller. Ultimately, the nurse ends the call after checking for mutual agreement and understanding, giving safety-net advice, deciding on whether to keep monitoring the caller and rounding off the call.ConclusionThe phases of the telephone nursing dialogue process as described in the scientific literature are well aligned with the theoretical descriptions of the telephone nursing dialogue process.
