Aims and objectivesThe aim of the study was to explore older persons' experiences of telephone advice nursing at primary healthcare centres. BackgroundTelephone advice nursing is expanding worldwide, and the older population is increasing. Little is known about older persons' experiences of telephone advice nursing provided by primary healthcare. DesignThis study has a descriptive design with a qualitative inductive approach. MethodsData were collected via interviews with a purposive sample of 10 older persons in 2014. The data were analysed using qualitative content analysis. ResultsThe older persons' experiences were described in two themes: the patient-friendly aspects of telephone advice nursing and the patient-unfriendly aspects of telephone advice nursing. The themes can be understood as two sides of the same coin; the differences point to both the advantages and disadvantages of the service and are further illuminated through seven subthemes. ConclusionsThis study contributes to increased awareness of the advantages and disadvantages of the telephone advice nursing system as experienced by older persons. To be the focus of attention during calls was highlighted as important; and clear communication was deemed crucial. When the communication between the nurse and the older persons was perceived as good and the perspective of the caller was the focus, an experience of safety and satisfaction was described. Older persons had great confidence in the telephone nurses' competence and perceived their ability to access the service as mostly good, even if it was sometimes difficult to use the service. Relevance to clinical practiceThe communicative competence of telephone nurses is essential when providing telephone advice nursing to older persons. In addition, a person-centred approach is important to provide optimal care in telephone advice nursing.
