Hospital wastes management in Mazandaran province with emphasis on Genotoxic waste management

Hospital wastes with the content of infectious, pathologic, sharp, pharmaceupitical and genotoxic materials are classified as hazardous wastes. Of which, genotoxic residues wirh mutagenic and teratogenic effects are of most great concern on human health. Genetic wastes are referred to as cytotoxic, chemical, and radioactive drugs used to treat cancer or treat transplantation. The purpose of this study was to evaluate the management of hospital wastes in Mazandaran province with emphasis on genotoxic waste.

This descriptive cross-sectional study was carried out in 35 governmental and social hospitals in Mazandaran province to determine the satus of hospital waste with focus on geotoxic waste. The quanity, quality and management approaches of hospital and genotoxic wastes in the studied hospitals were surveyed with a validated questionnaire. Results obtained from the present study were analyzed with Excel software.

The average waste per each hospital bed was estimated to be 3.51 kilograms. Of which, 2.2, 1.24, 1.9 kg were categorized as municipal, chemical, and genotoxic wastes, respectively. The average of the hospital waste management index in Mazandaran province was found to be about 84 out of 100, indicating good management of these wastes. The management of genotoxic waste in 7 specialized chemotherapy hospitals was estimated to be 64 out of 100, indicating the average state of genotoxic waste management for these hospitals. In 28 non-chemotherapy hospitals, the genotoxic waste management index was approximated 42 out of 100, indicating poor management of these wastes.

The main weaknesses in hospital waste management are associated with the management of chemical-pharmaceutical and genotoxic wastes. Accordingly, improvement the quality of genotoxic and chemical-pharmaceutical wastes should be concerned in the future planning.
