Elaboración de un compendio de cálculos prácticos en farmacia clínica

Abstract

Abstract: In recent decades, the role of the hospital pharmacist has shifted from a medication-centered approach to one focused on the patient. Pharmaceutical interventions are among their core activities and require proficiency in pharmaceutical calculations; however, no consolidated reference guide covering these calculations currently exists in Ecuador. The objective of this study was to develop a compendium of practical calculations in clinical pharmacy. The methodology consisted of a systematic literature review using Boolean search equations divided into six thematic blocks, followed by a screening and eligibility process based on inclusion and exclusion criteria, analysis using the PRISMA Extension for Scoping Reviews (PRISMA-ScR) methodology, and classification according to Oxford levels of evidence. A bibliographic base of 122 references was compiled, with a core of level 1a 1b sources supporting the most clinically sensitive areas. The review revealed a marked dispersion and fragmentation of knowledge in the field of pharmaceutical calculations, a scarcity of Latin American scientific output in this area, and the suitability of dimensional analysis as the standard method for reducing calculation errors. The final product is a document structured into seven progressive chapters with practical exercises solved step by step. The compendium addresses a genuine need in Ecuadorian hospital pharmacy practice and contributes to mitigating patient safety risks arising from academic gaps in this field.
