Resíduos de serviços de saúde: perfil e análise de custos em um centro cirúrgico

Objective: To determine the waste generation profile and measure the costs of materials used in medical waste management in a surgical site. Method: This is an exploratory-descriptive survey, with a quantitative approach, in the case study modality. The site was the surgical site of the University Hospital of Universidade de Sao Paulo. The stratified sample was of 1,120 surgeries, and the waste was weighed for 82 days. Results: The surgical site waste accounted for 6.38% of the total hospital waste. The most representative group was A-infectious (50.62%). The mean generation was 3.72 kg per surgery. Most of the waste was generated in the operating room (55.93%), and oral maxillary surgeries generated most of the waste in terms of mass. The cost per kilo was: Group A (R$ 1.10), Group B (R$ 5.70), Group D Recycled (R$ 0.96), Group D Nonrecycled (R$ 1.01) and Group E (R$ 3.23). Conclusion: The mean total cost per surgery was R$ 8.641, and its reduction depends on strategies of purchasing consumable supplies that had greater impact on costs.
