已经提到,科学管理f waste generated during patient care is essential as well as a legal liability of the generator. Unfortunately, complacency and inadequate knowledge followed by practice for waste disposal leads to various kinds of community and individual health and environment issues which are detrimental to the human life. The present study is aimed to take an account of scientific knowledge and it’s practical applicability of BMW among the general practitioners of Mumbai city in India. In the present study general practitioners in Mumbai city were visited and interviewed personally and also administered questionnaire in order to analyse biomedical waste management by general practitioners. 37 (30.8%) belongs to age group 14-50 years followed by 30-40 years (30%). The percentage of male (64.1%) is more than female (35.8%) practitioners. The qualification ranged from BHMS, BAMS, MBBS to MD of which majority ware medical graduates (40.8%). 66.6% practitioners had average while only 23.3% has good knowledge about proper waste management. Maximum concern was shown towards the safety where it scored 80% followed by waste generation (62%), definition (51%), transportation (46%), Colour coding (34%). The study brought out the facts that the deficiency of knowledge and practices of waste management were the main reason for non scientific management of waste generated by general practitioners thus exposing self as well as community at large to health and environment hazards.

Introduction

Biomedical waste is the unwanted materials generated during diagnosis, treatment, operation, immunization and research activities. These wastes are potential source of infections namely HBV, HCV, HIV, and tetanus. It has been estimated that around 1.45 kg waste is generated per patient per day in Indian hospitals (4.5 kg in developed countries).1Out of this quantity about 15-20% of this total waste is hazardous,1while in India the percentage might be much higher of lack of proper and scientific waste segregation and waste disposal methods. Extensively reported in country’s print media that re-use of disposable syringes, needles, catheters, bags, drug vials, bottles, and intravenous drip sets are picked up by rag pickers and purchased by duplicators, recycled, replaced without proper treatment.2It is also noted that the maintenance of the incinerators used by some of the hospitals is so poor that instead of helping the clean environment they contribute to pollute the environment because of improper segregation of the wastes used in incinerators.3The ‘Bio-medical waste (management and handling) Rules 1998’ was enacted in 1998 and got amended thereafter various times, lastly in 2003. Any violation of the rules by any person is punishable with fine or imprisonment under the Environment protection Act 1986.2In India health care providers may be having adequate knowledge, but the practices are deficient and inappropriate due to lack of proper facilities, interest of the individual or inadequate knowledge. With this view the present study was done to take account of knowledge and practice on bio-medical waste management among general practitioners in Mumbai city, India.

Therefore, knowing the present status of locally based healthcare providers awareness regarding BMWM will help the authorities to revise and redo the strategy for improving the situation in future.4,5,6

StudyObjective

  1. To identify the average knowledge level of biomedical waste management among general practitioners.
  2. 确定生物医学的实践水平aste management by general practitioners.
  3. To recommend system to optimize the scientific management of biomedical waste to prevent transmission of waste related infections in the community.


Scope of the Study

Scientific management of biomedical waste is very vital step in prevention of infection transmission. There is increasing concern about increasing load of biomedical waste in public. Though the knowledge is there however the conversion of such knowledge in to practice is the essence of scientific management of biomedical waste. There is inverse relationship between transmission of disease and level of management.

The study is an attempt to reveal the correct picture of current scenario about biomedical waste management among general practitioners so as to take necessary steps to improve it’s management.

With the help of available statistical information the correlation between knowledge and practice were analyzed by Spearman’s Rank correlation method, and it was found that there was positive correlation between knowledge and practice atP<0.012. This indicated that the practices of health care providers on bio-medical waste management were influenced by their level of knowledge. This result indicates that that the knowledge about waste management possessed by General Practitioners was not dependent on any of the socio-demographic variables.

For the purpose of studying association between sociodemographic variables and practice scores there is no significant association was found with these demographic variables. But the calculated chi-square value (17.96) for total year of experience was more than tabulated value which indicate significant association between practice and total year of experience. This finding indicated that the practices regarding scientific way of managing biomedical waste remain dependent on years of experience as the experience increased the safer they wish to be in their practices.

Conclusion

The study besides the statistical results it provided the following information about the knowledge and practices of biomedical waste management by General Practitioners of Mumbai city. It is noteworthy that care providers should have proper knowledge and adequate practice bio-medical waste management in better way to protect self, the community and more importantly the environment.

It is also to be stressed that awareness and knowledge has its own limitations and Its application is solely dependent on the level of knowledge the subject possesses however these limitation should not deter medical professionals to adapt the scientific process of biomedical waste management. Alas, periodical education will also enhance the practices of the proper bio-medical waste management.

It is imperative that active participation in knowledge sharing be encouraged among General practitioners. Various research activities are being undertaken to know the hazardous effects caused by unscientific management of biomedical waste and their prevention among health care providers. The information provided by helps healthcare providers to focus on health hazards from the waste and lays foundation upon which the new scientific knowledge is based.

Because of the small sample size the broad generalization could not be made and needs further study with large sample size so as to make generalized conclusion.

The research base can further be broaden by performing comparative study at different levels and with different categories of healthcare providers. With the recommendations of establishing bio-medical waste management control committee to lay down the policies regarding management and team to monitor the activities among medical professionals is pertinent.
