Integrating Digital Health into School Nursing for Food Allergy Management: A Systematic Review

Background: Food allergy [FA] is a growing public health concern among school-age children, with schools and childcare/daycare settings representing high-risk environments for accidental exposure and anaphylaxis. Objective: To systematically review evidence on digital health interventions supporting FA education, prevention, and management in school settings. Methods: A systematic search of PubMed, Scopus, Web of Science, and CINAHL was conducted to identify studies published between January 2015 and December 2025 [PROSPERO CRD420251185553]. Eligible studies evaluated e-learning, mHealth, or web-based programs targeting school staff, parents, or students. Results: Sixteen studies met inclusion criteria. Digital health emerged as a catalyst for professional development, interprofessional communication, and health equity within school communities. Interventions consistently improved knowledge, preparedness, and self-efficacy in anaphylaxis management among school staff, strengthened parental empowerment and communication with schools, and supported coping and inclusion among allergic children. Evidence on clinical outcomes; however, remains limited. Conclusions: Digital health can meaningfully enhance school preparedness and reduce inequalities in allergy management. Integrating digital tools into national school health frameworks—particularly where school nursing is not yet institutionalized—may represent a pivotal step toward safer, more equitable inclusion of children with food allergy.
