title: Assessment of medical waste management at a primary health-care center in São Paulo, Brazil.
abstract: According to the Brazilian law, implementation of a Medical Waste Management Plan (MWMP) in health-care units is mandatory, but as far as we know evaluation of such implementation has not taken place yet. The purpose of the present study is to evaluate the improvements deriving from the implementation of a MWMP in a Primary Health-care Center (PHC) located in the city of São Paulo, Brazil. The method proposed for evaluation compares the first situation prevailing at this PHC with the situation 1 year after implementation of the MWMP, thus allowing verification of the evolution of the PHC performance. For prior and post-diagnosis, the method was based on: (1) application of a tool (check list) which considered all legal requirements in force; (2) quantification of solid waste subdivided into three categories: infectious waste and sharp devices, recyclable materials and non-recyclable waste; and (3) identification of non-conformity practices. Lack of knowledge on the pertinent legislation by health workers has contributed to non-conformity instances. The legal requirements in force in Brazil today gave origin to a tool (check list) which was utilized in the management of medical waste at the health-care unit studied. This tool resulted into an adequate and simple instrument, required a low investment, allowed collecting data to feed indicators and also conquered the participation of the unit whole staff. Several non-conformities identified in the first diagnosis could be corrected by the instrument utilized. Total waste generation increased 9.8%, but it was possible to reduce the volume of non-recyclable materials (11%) and increase the volume of recyclable materials (4%). It was also possible to segregate organic waste (7%), which was forwarded for production of compost. The rate of infectious waste generation in critical areas decreased from 0.021 to 0.018 kg/procedure. Many improvements have been observed, and now the PHC complies with most of legal requirements, offers periodic training and better biosafety conditions to workers, has reduced the volume of waste sent to sanitary landfills, and has introduced indicators for monitoring its own performance. This evaluation method might subsidize the creation and evaluation of medical waste management plans in similar heath institutions.
