Diabetes mellitus is the most common metabolic disorder in childhood. Today, children with diabetes are receiving new technologically advanced treatment options, such as continuous subcutaneous insulin infusion (CSII) therapy. School nurses are the primary health caregivers of children with diabetes during school hours. Therefore, it is important to determine their perceptions, resources, and resource needs when caring for students with continuous subcutaneous insulin infusion or insulin pump therapy. This study uses a phenomenological approach to examine the experiences of school nurses caring for students receiving insulin pump therapy. Eleven school nurses were interviewed using semistructured taped interviews. The nurses' responses indicated that they were "scared" when first caring for students with continuous subcutaneous insulin infusion therapy. However, they were able to work through their fear by using their resources and gaining more knowledge and hands-on experience with insulin pumps. The data also revealed that school nurses who were able to learn the language of continuous subcutaneous insulin infusion therapy and successfully deal with pump problems developed trusting and knowing relationships with students, teachers, and parents.
