Reaproveitamento de materiais plásticos estéreis pelo tratamento por radiação gama: logística reversa de insumos laboratoriais em uma instituição de ensino superior

Abstract

The supply chain in the public or private educational institutions, focused on laboratory diagnosis in the health area should be managed according to standards of quality and relevant to biosafety laws. The cost and the optimization of the use of these materials is an important factor in health centers or diagnostic organizations, taking into account the reverse logistics leftover of packages of sterile supplies for improvement in sustainability. A health organization integrates as subsystem to serve the needs of inputs (consumption materials) and equipment (permanent material). These activities are complex and demand a specific mix of inputs, layered on a supply chain that incorporates sequences of actions defined for the generation of their products or procedures. The Supply Chain encompasses all activities related to the flux and transformation through which the product passes, since the raw materials to the final consumer. With the growing concern about the environment and the competitive nature of the market, the importance of the reverse flow of materials and products, has been taking larger proportions. The management of this reverse path of these materials, when compared to the direct flow of the supply chain, is called reverse logistics. The nosocomial infection affects around the world and is one of the causes of death in hospitalized patients, the sensitivity tests are shown to any microorganism that causes an infectious process requiring antimicrobial therapy. The preparation of the Petri dishes for antibiogram tests involves the use of sterile materials, which are often not fully utilized in a laboratory. This loss of leftover material is a break in the supply of an educational institution or diagnostic laboratory chain. The overall goal of this work is to identify how reverse logistics practices can influence the cost savings of a laboratory of an Institution of Higher Education (IHE), with the use of ionizing radiation treatment on plastic materials for sterile use, since after the package is opened and the no use of all the units of their content, makes it impossible to application of these materials in good condition, as the Petri dishes in microbiological testing in laboratories.
