Fuzzy Visa: a fuzzy logic model for risk assessment of Health Surveillance for health services waste inspection

Abstract

The sanitary inspection of Health Services Waste Management (HSWM) lacks a standardized work methodology that provides a secure basis for evaluating potential risk (PR). This study aimed to propose an instrument based on fuzzy logic that could standardize inspection and generate indicators of sanitary control. The model was developed with 18 subsystems related to HSWM obtained from the assembly of elements identified in the inspection as those that interfere with the assessment and permeate all stages of HSWM. The validation of the model was conducted in 10 health establishments in Rio de Janeiro between May to November 2009. The results obtained by this model were consistent with the diagnoses made by experts and clearly indicated the possibility of the systematization and rationalization of PR assessments. This decision support system makes management and planning of actions more efficient in PR evaluation.
