Development of a mobile application for emergency shift handovers using the National Early Warning Score.

Objective: To develop and validate a prototype of a mobile application shift handover between nurses in the emergency room using a severity scale.

Method: This is a technological tool carried out at the Universidade Estadual de Maringá using design thinking, divided into four phases: discovering, defining, developing, and delivering. To structure the information, a checklist was used based on the Situation Background Assessment Recommendation, and to categorize patients in terms of severity, the National Early Warning Score was used. The validation of the sample was carried out by 10 nurses, specialized in the field of urgency and emergency, using the System Usability Scale questionnaire to assess usability. The content validity coefficient was used for analysis.

Results: The application scored 75.75 in usability and had a content validity coefficient of 0.8.

Conclusion: The prototype obtained an excellent evaluation of usability and agreement between evaluators. Future studies are needed for implementation in practice, evaluating the practicality, applicability, efficiency and time savings in shift information transfer.
