Impactos da implementação do lean healthcare no setor de Ressonância Magnética em uma clínica de diagnóstico por imagem

Abstract

The growing demand for imaging exams and limited resources in healthcare services motivated the adoption of Lean Healthcare (LH) as a management strategy to increase productivity in the magnetic resonance imaging (MRI) sector. This study aimed to implement and analyze the impacts of LH combined with process management in a diagnostic imaging clinic located in Natal/RN, Brazil. The sample included MRI procedures performed between 2023 and 2024. This action research involved process mapping using Bizagi Modeler, interviews with professionals, direct observations, and data extraction from the clinic’s management system. Interventions were structured according to the PDCA cycle, including training sessions, standardizations, and workflow reorganization. Statistical analysis considered indicators such as the number of exams, average service time (AST), and revenue. Results showed a progressive increase in monthly production, with a 41% growth in productivity and a 36% increase in revenue. The AST dropped from 40 to 28 minutes. The discussion showed that workflow reorganization, staff training, and better use of available resources were essential to the results. The implementation of LH proved effective in improving productivity and care quality without requiring additional investment in infrastructure or staff, highlighting its potential for replication in other healthcare contexts facing similar limitations.
