ABSTRACT
Objective
To verify the impact of the Lean Six Sigma methodology in reducing incorrect entries of non-appropriated revenues and expenses.
Methods
Process for the review and application of the Lean Six Sigma methodology between December 2015 and September 2016, in a high-complexity general hospital in the city of São Paulo (SP).
Results
A total of 3,756,814 (100%) entries were audited between December 2015 and September 2016. The Sigma level evolved over the course of the process and increased from 3.44 Sigma in December 2015 to 5.92 Sigma in September 2016. Entries classified as non-appropriated revenues and expenses were brought down to 0% at the end of the study.
Conclusion
The use of the Lean Six Sigma methodology was efficient in reducing incorrect entries, calculating costs, ensuring compliance in rendering of accounts and accurately determining cost-outcome ratios.
