Evaluating the initial effectiveness of lean management in the outpatient examination process at the Viet Duc University Hospital

Abstract

The study’s primary objective was to assess the initial effectiveness of lean management in the outpatient examination process at the Cardiovascular Clinic - Viet Duc University Hospital. Object: The research used data on examination time and patient volumes at the clinic between October 2022 and April 2023. Methodology: Interventional study based on the Define, Measure, Analyze, Improve, and Control (DMAIC) cycle. The intervention results revealed a reduction in the waiting time for examinations, decreasing from 29.42 to 27.38 minutes. Moreover, specific steps
within the examination process demonstrated decreased time durations, including the duration for an X-ray, which decreased from 217 to 167 minutes, and a 64-128 CT scan, which decreased from 201 to 108 minutes. Overall, the patient examination time was reduced by approximately 7.1 to 9.1%. In conclusion, the findings indicate an improvement in the outpatient examination process following the implementation of lean management practices, resulting in a decrease in examination time and thereby enhancing the satisfaction of the patient.
