Implementing Lean In Operating Room Medical Supplies Of RSIA Grand Family

This research aims to assess the results of lean implementation in reducing the cost of medical supplies in the operating room of a hospital in Indonesia. These results can be used as a motivation to extend implementation to other aspects of overall operating room and hospital management. Resource inventory to build management commitment, willingness to share data, and information of implementation history was the initial stage of research. Furthermore, the research was conducted by applying 5S methodology to medical supplies in the operating room of RSIA Grand Family, Jakarta. The 5S procedure then was evaluated using descriptive and inferential statistics. The inferential statistics used was Wilcoxon Signed Rank test. Lean implementation that was carried out successfully reduced inventory costs to an average of Rp 331,555,768 per month in three months after lean implementation, from Rp 381,140,031 per month in the previous three months before lean implementation. This means that there is a cost reduction of 13.01%. Furthermore, the number of medical supplies items was reduced by an average of 12.45%. This research has a number of limitations. First, this research was conducted on the aspect of medical supplies from the operating room. Second, this research was still on a small scale and only evaluated the cost aspect of medical supplies.
