Preventive home visits carried out by healthcare professionals are intended to promote the health and independence of home-dwelling older persons and to prevent functional decline. The aim of this study was to describe nurses’ experiences of the benefits from long-term follow up with annual preventive home visits to older people in a Norwegian context. We conducted semi-structured interviews with nine nurses who performed the service. Manifest and latent content analysis revealed benefits within three themes: sustained ability to live independently and thrive despite age-related changes, eased transition to other healthcare services, and improved healthcare service planning. Two headlines describe the longitudinal processes involved in the creation of benefits: ‘The processes of establishing, sustaining, and widening a longitudinal room of possibilities’ and The individualized health-promoting processes – the ongoing gardening work. Professional, contextual and structural factors influenced the nurses’ ability to support older persons’ changing needs during the aging process and thus their health and independence.
