User evaluation of the APP NAS software in intensive care unit

PURPOSE: The Nursing Activities Score (NAS) is a management tool that measures nursing workload, quantifying the care and the degree of complexity involved in the assistance, and can subsidize the managers for an adequate dimensioning of the team. OBJECTIVE: The objective of this study is to evaluate impressions of users who work in the intensive care unit (ICU) of APP NAS in the APP and WEB modules, comparing them with classical methods of score evaluation: printed paper (PP) and/or spreadsheet (SS). METHODS: This was a longitudinal, quantitative-descriptive study with professional nurses working in the intensive care of a University Hospital in Brazil. For the assessment test, the quality assessment process model was used, according to the NBR ISO / IEC 9126-1 standard employing the Questionnaire for User Interaction Satisfaction (QUIS). The research participants were nurses and nursing residents (n = 9) working in an ICU for at least 3 months in the institution. QUIS allows the evaluation of the following domains by grouping questions for each study group: general impressions, functionality, reliability, usability, efficiency, and maintainability. RESULTS: Statistically significant satisfaction scores (p < 0.05) were observed in APP NAS when comparing to the classical methods (PP and SS) in the evaluated characteristics except for reliability. CONCLUSION: Our data showed broad approval of the APP NAS when comparing to classical methods making the software viable for implementation in ICUs of hospitals.
