Guía Terapéutica Antibiótica is a free app developed by Go-Space Solutions for Android devices. The app aims to promote better use of antimicrobials and provide access to other resources such as medical calculators, courses, and clinical cases. The app is intended for medical and pharmaceutical professionals in general and encompasses both general aspects of antimicrobial use as well as concrete treatment apparatus. The app provides off-line reading of the general aspects of antimicrobial use, treatment protocols, and prophylaxis protocols. Additionally, it offers clinical calculators such as BMI, dose obese, renal function, CPIS scale, scale CURB-65, Fine scale (PSI), Child-Pugh scale, Barthel index, and Pfeiffer test. The app also provides access to courses on infectious diseases taught in recent years. Furthermore, every 15 days, a new clinical case is presented, and a questionnaire is released, which is later resolved and discussed. Users can also send their comments, corrections, or suggestions to improve the application via the app's suggestions section.
