Abstract

The CalcVAN app was developed to assist healthcare professionals in optimizing vancomycin doses for hospitalized patients. However, the usability test before making it available for clinical practice is essential. Therefore, the study aims to evaluate the usability of the app from the perspective of health professionals. A descriptive study, a heuristic evaluation of the usability of a mobile application was conducted. Healthcare professionals with expertise in antimicrobial management and vancomycin were invited to participate. The validated Smartphone Usability questionnaiRE (SURE) was used to measure usability through an online questionnaire. Twenty-one experts participated in the study, with a mean age of 32.6 years, mostly of them women (n = 14, 66.7%), pharmacists (n = 13, 61.9%), with postgraduate education (n = 10, 47.6%), working in private or public hospitals (n = 15, 71.4%), and a mean experience of 9.7 years. Overall usability score for CalcVAN was 83 points, ranging from a minimum of 78 to a maximum of 90 points. The usability test registered within the last two levels, 70 and 80, with users expressing strongly and fully agreed, indicating that the app demonstrates satisfactory usability. CalcVAN achieved satisfactory usability, fulfilling the needs and requirements of health professionals, proving to be efficient in performing the intended functions.
