Usability of volumetric infusion pumps in pediatric intensive care

Abstract

Objective: To analyze the usability of two infusion pump models in a Pediatric Intensive Care Unit. Method: This is a cross-sectional study of exploratory descriptive quantitative approach. A task was carried out in a controlled environment using infusion pump with 72 nursing staff members from August to September 2018. The Methodological Guideline for Medical Care Equipment Assessment Studies and the quality model proposed by NBR ISO/IEC 9126-1 were followed. Descriptive statistical analysis was used applying Fisher’s exact test, binomial test and Mann-Whitney test. Results: 91.7% of tasks were completed. The infusion pump-2 model was associated (p < 0.001) with operationalization, tasks accomplished with non-conformities, use of a manual calculator (measure effectiveness) and task accomplishment time (measure efficiency). Conclusion: Efficacy and efficiency measures can evidence a better context of usability of IPs and identify interaction failures with the nursing staff to be improved in care practice.
