Concepção de Sistema de Apoio à Tomada de Decisões para Assistência de Enfermagem em Terapia Intensiva Cardiológica

Abstract

The Systems of Decision Making Support (SDMS) are interactive systems designed to help health professionals in solving complex clinical problems. In the nursing field, such technology emerges as a foundation for a leap in quality of the care, management, teaching and research; being, the Intensive Care Units (ICU), sectors particularly benefited by the use of SDMS. This study has the general objective: To develop a system of decision making support for nursing care in cardiac intensive care unit, from user requirements validated by experts; and specific objectives: To identify, analyze and validate the user requirements for the development of a software of decision making support for the nursing care in cardiac intensive care unit and plan and build the software operation flowchart. It is an applied production technology research, which followed the steps of the Requirements Engineering process proposed by Ian Sommerville. The place chosen for the technology was the Cardiac ICU of a Brazilian hospital. The activity of elicitation and analysis of the requirements enabled the identification of 71 user requirements, as follows: 31 requirements identified through the integrative review, 23 through ethnography and 17 by developing use cases. The development of the requirements validation step proved be very important to the software design, since the specified requirements are incomplete and susceptible to error. The verifications made at this stage, with the involvement of nurses and software engineering professionals ensured the validity, consistency, completeness and realism of the identified requirements, leaving them ready to base the development of the proposed software. Furthermore, the validation activity proved to be important not only to ensure the validity of elicited and evaluated requirements, but also for being a source of 59 new software requirements. The results show that the design of a software based on the engineering requirements, with direct and active involvement of nurses, is a complex process, but essential for the development of a software of decision making support for nursing care.
