IMPACTO DE LA METODOLOGÍA LEAN EN LA PERMANENCIA DE PACIENTES DE UN SERVICIO DE EMERGENCIAS

Objective: To identify the average length of patients’ stay before and after the Lean methodology application in a Teaching Hospital’s Emergency Room. Method: cross-sectional, retrospective, documentary, quantitative study. The data was collected in December 2019 via the TASY system. The list of patients admitted to the emergency room, from November 2018 to November 2019, in Western Paraná – Brazil, was obtained. A descriptive statistical analysis was carried out, and the Statistica 7.0 program was used, with Levene and Scheff tests. Results: there was an increase of 61% in the number of hospitalizations, a 30% reduction in the stay, and 26% of the maximum stay recorded. However, there was no significant difference in the period before and after Lean in the stay length. Conclusion: it was evident that Lean can potentially collaborate in improving the patients’ flow, increasing the visits, and reducing the stay period in the unit.
