ABSTRACT
Objective:
to develop a multi-platform mobile application for the prevention of musculoskeletal risk factors related to nursing work in a hospital unit and to evaluate the usability criteria with nurses and computer professionals.
Method:
technological production study for the development of a mobile application, following the phases of software engineering: analysis of requirements, design and specification, construction, internal tests, maintenance and external evaluation. The product was evaluated for usability by nurses from public hospital units in the city of Rio de Janeiro (Brazil). The System Usability Scale instrument was used for the evaluation of the nurses and the instrument of heuristics of compliance of digital interfaces was used with the informational technology professionals. The application development period lasted from November 2017 to March 2018 and the usability assessment from March to May 2018.
Results:
the evaluation data showed that the application shows agreement and compliance with the principles of usability in the criteria of effectiveness, efficiency and user satisfaction, however, the evaluators suggest that the application's functionalities should be simplified.
Conclusion:
the application was designed as a care strategy for the nursing professional, considering the musculoskeletal risks which they are exposed to in their professional activities. The development and evaluation methods were satisfactory and the proposed objectives were achieved.
