Healthcare waste disposal strategy selection using grey-AHP approach

Purpose Nowadays healthcare waste (HCW) has become a big challenge for the hospital management, especially, in developing countries like India. Like other developing countries, Indian healthcare waste disposal (HCWD) industry is also fragmented, as some hospitals are having their own in-house waste treatment facilities and others are outsourcing the process to government authorized Common Biomedical Waste Treatment Facilities. Literature also lacks the quantitative studies in selecting the HCWD strategy and, hence, the purpose of this paper is to identify and prioritize the factors, which affect the selection of HCWD strategy and to propose the model to select the HCWD strategy and to apply the proposed model to select the HCWD strategy in Uttarakhand, Northern State of India. Design/methodology/approach Grey theory-based analytic hierarchy process approach has been applied to evaluate the HCWD options and select the appropriate strategy for the healthcare facilities (HCFs). Findings From the literature, six criteria have been used to evaluate the HCWD strategies: “access to expertise,” “overdependence,” “transportation & risk associated,” “Government rules,” “environmental factors,” and “economic factors.” “Outsourcing” strategic option (0.61) got the higher desirability index than “in-house treatment” (0.39). Research limitations/implications The proposed methodology can be used by the researchers and experts in the field to evaluate the strategic options and select the appropriate strategy. Practical implications The HCFs and other generators of HCW can select the alternative, whether they should treat the infectious waste in-house or they should go for outsourcing. Originality/value In the field of HCW management, this is the first study of its kind, which helps to evaluate and select the HCWD strategies. The proposed model has been applied in Uttarakhand, Northern State of India to make the comparison between “in-house” and “outsource” strategies.
