Research on biomedical Waste Management

Proper management of Biomedical waste (BMW) generated in a healthcare facility is one of the most important functions of a healthcare worker (HCW) as its improper management not only poses risk to human beings and environment, but may also invite legal action against HCW as well as hospital administration. This study was carried out to evaluate quality of BMW management in 1100-bedded hospital attached to a tertiary care public institute in North India.

Methods

A checklist, including 29 parameters related to various functions to be carried out at source of generation by a HCW for BMW management was prepared by researcher and used after validation to record observations in all the 70 areas of hospital. A total of 6 visits were made to each area and mean percentage score was calculated for each area and each category of waste management.

Results

It was found that summated mean percentage score of ‘Treatment Room of Wards’, which were used exclusively by resident doctors, was significantly lower than Operation Theatres (p value: 0.033) and ‘Central Waste Collection Points of Wards’ (p value: 0.018) for the function of ‘mutilation of recyclable waste’ and it was significantly lower than all other areas (p value: 0.006 to 0.017) for the function of ‘disinfection of waste’.

Conclusion

It is concluded that more emphasis needs to be laid on ‘mutilation of recyclable waste’ and disinfection of waste’ by HCWs especially resident doctors.
