Nursing Activities Score: trajectory of the instrument from paper to cloud in a university hospital.

Objective: To report the process of organization and construction of an information technology structure named Nursing Activities Score (NAS) Cloud Technology®.
Method: This project was based on the life cycle theory and has enabled the development of technological production through software engineering.
Results: The NAS Cloud Technology® was developed for remote and collaborative access on a website hosted by Google Sites® and protected in a business environment by the certified security and data protection devices Health Insurance Portability and Accountability Act (HIPPA). In 2015, this system received more than 10.000 submissions/month, totaling 12 care units for critical patients covered by the information technology structure, circa 200 nurses per day involved in the collection and hundreds of daily submissions, integrating the complete transition from paper to cloud.
Conclusion: The development of NAS Cloud Technology® system has enabled the use of technology as a facilitating means for the use of Nursing care data, providing tools for decision-making on the nursing personnel sizing required for the care demands in the inpatient care units. The potential of cloud structures stands out due to their possibility of innovation, as well as low-cost access and high replicability of the information system.
