O Lean Manufacturing aplicado à tecnologia médico-hospitalar

Abstract

The movement for quality and the pursuit of safety in health services is a worldwide phenomenon, due to the growing awareness that, in contemporary society, quality is considered an indispensable requirement of economic survival and, more importantly, according to some authors, a ethical and social responsibility. The hospital maintenance sector, along with the steel / mining sectors, are considered sectors that present the highest cost, of the order of 5 to 10% of the billing in private hospitals. The essential mission of hospital institutions is to serve their patients in the most appropriate way. Therefore, every hospital should be concerned with the permanent improvement of the quality of its management and assistance, seeking a harmonious integration of the medical, technological, administrative, economic, care and, where appropriate, teaching and research areas. The objective of this research was to carry out an improvement plan to be developed at the Heitor Vieira Dourado Tropical Medicine Foundation (FMT_HVD) for the maintenance area in virology management, aiming to improve the activities performed within it, reducing maintenance time of the used machines in this management and change the layout in order to optimize employee time and space within the lab. Lean Manufacturing management tools were used, such as TPM (Total Productive Maintenance) and a database was created with all the operations performed by the management in the virology sector, aiming the monitoring of the useful life of the hospital equipment. After all analyzes in the virology sector and improvements were applied according to Lean Manufacturing methodology, there was a 63% gain in equipment downtime for corrective maintenance due to preventive maintenance. And with regard to the new layout implemented, there was an efficiency gain of 30% with the elimination of wasted time in conducting the tests. The Lean Manufacturing tools proved to be of great value as a way to improve the quality of services performed by increasing productivity and reducing equipment maintenance time, as well as presenting a management philosophy aimed at reducing expenses and waste.
