Aims and objectives To explore experiences of negative pressure wound therapy at home, in patients with deep perivascular groin infection after vascular surgery and management in daily life. Background Deep surgical site infection after vascular surgery with exposed vessels often requires long-term treatment with negative pressure wound therapy, and continued therapy at home has become routine. Design An explorative qualitative study. Methods Nine men and six women with a deep surgical site infection in the groin after vascular surgery, treated in their home with negative pressure wound therapy, were interviewed. The interviews were analysed using manifest and latent content analysis. Results Undergoing negative pressure wound therapy at home meant a transition from being a dependent patient to a person who must have self-care competence and be involved in their own care. A need to feel prepared for this before discharge from hospital was expressed. Lack of information and feelings of uncertainty prolonged the time before feeling confident in managing the treatment. The informants gradually accepted the need to be tied up to a machine, became competent in its management and found solutions to perform everyday tasks. Overall, it was a relief to be treated at home. Conclusions Several benefits of negative pressure wound therapy at home were expressed. However, unnecessary stress and anxiety were experienced due to a lack of information on the treatment and instruction concerning the equipment. Adequate information and education must therefore be provided to facilitate the transition from a patient to a person with self-care competence and ability to manage this treatment at home. Relevance to clinical practice The findings revealed a need for more support and knowledge in their transition from hospital care to home care with negative pressure wound therapy. Routines must be established that ensure patient safety and security in treatment at home.
