Article history: Hospitals and other healthcare establishments have a ‘‘duty of care” for the environment and for public
Accepted 2 June 2008 health, and have particular responsibilities in relation to the waste they produce (i.e., biomedical waste).
Available online 5 August 2008 Negligence, in terms of biomedical waste management, significantly contributes to polluting the environ-
ment, affects the health of human beings, and depletes natural and financial resources. In India, in view of
the serious situation of biomedical waste management, the Ministry of Environment and Forests, within
the Government of India, ratified the Biomedical Waste (Management and Handling) Rules, in July 1998.
The present paper provides a brief description of the biomedical waste (Management and Handling)
Rules 1998, and the current biomedical waste management practices in one of the premier healthcare
establishments of Lucknow, the Vivekananda Polyclinic. The objective in undertaking this study was to
analyse the biomedical waste management system, including policy, practice (i.e., storage, collection,
transportation and disposal), and compliance with the standards prescribed under the regulatory frame-
work.
The analysis consisted of interviews with medical authorities, doctors, and paramedical staff involved
in the management of the biomedical wastes in the Polyclinic. Other important stakeholders that were
consulted and interviewed included environmental engineers (looking after the Biomedical Waste Cell)
of the State Pollution Control Board, and randomly selected patients and visitors to the Polyclinic. A gen-
eral survey of the facilities of the Polyclinic was undertaken to ascertain the efficacy of the implemented
measures. The waste was quantified based on random samples collected from each ward. It was found
that, although the Polyclinic in general abides by the prescribed regulations for the treatment and dis-
posal of biomedical waste, there is a need to further build the capacity of the Polyclinic and its staff in
terms of providing state-of-the-art facilities and on-going training in order to develop a model biomedical
waste management system in the Polyclinic. There is also a need to create awareness among all other
stakeholders about the importance of biomedical waste management and related regulations.
Furthermore, healthcare waste management should go beyond data compilation, enforcement of regula-
tions, and acquisition of better equipment. It should be supported through appropriate education, train-
ing, and the commitment of the healthcare staff and management and healthcare managers within an
effective policy and legislative framework.
