CHAPTER ONE
INTRODUCTION
1.0 Background to the Study
Healthcare waste threatens the public health due to its contagious nature. Most healthcare facilities are located in the heart of the cities and therefore, healthcare waste that are not correctly managed can cause dangerous infection and pose potential threat to the nearby environment, health workers, patients and to the public (WHO, 2014). Dehghani, Azam, Changani and Fard (2008) noted that Healthcare Waste (HCW) if not appropriately managed can be a serious threat to human health due to their infectious attributes. Nigeria, one of developing countries, has health issues that are competing for limited resources; it is not amazing that healthcare waste management receives less attention and precedence than it merits (Stephen, & Elijah, 2011). Therefore, there is a serious challenge in developing countries, where there are no Institutional provisionsfor healthcare waste management. Clinical wastes are disposed openly in the dumpsite along with municipal waste and the practice make the members of the community gain access to it which may lead to outbreak of infectious diseases (Alagoz, Kocasay, Abah, & Ohimain, 2010) . Cheng, Sung, Yang, Lo, Chung and Li (2009) noted that as small as healthcare waste is in proportion to the total community waste, its management is considered an important issue worldwide. World Health Organization (2014) reported that 15% of total waste generated in the healthcare facility is hazardous and must be properly segregated at the point of generation to prevent the whole healthcare waste becoming 100% hazardous. The World Health Organization estimates that each year there are about 8 to 16 million new cases of Hepatitis B virus (HBV), 2.3 to 4.7 million cases of Hepatitis C virus (HCV) and 80,000 to 160,000 cases of human immune deficiency virus (HIV) due to unsafe injections disposal and mostly due to very poor waste management systems.
Across the globe, the risk associated with Healthcare Waste (HCW) and its management has gained tremendous attention from health practitioners and non practitioners. If healthcare facilities know the types and quantities of clinical waste generated, it will help them in planning, budgeting adequate revenue for the management of hazardous waste (Bongayi, 2013). A study conducted by Olubukola (2009) in two General hospitals at Lagos reported that due to lack of quantification of healthcare waste, there was no waste reduction plan in the hospitals.
This lack of plan for healthcare waste management eventually leads to inadequate waste segregation at point of use, collection, storage and final disposal. This poor healthcare waste management practice creates health hazards for health workers, patients and the environment. Identified gaps like lack of colour code bags for segregation of healthcare waste at point of use, lack of guidelines on segregation and disposal for health workers lead to poor healthcare waste management in hospitals. The mismanagement of healthcare waste by healthcare facilities does not pose health hazard to health workers and patients alone but also to patients’ visitors and the community where they are improperly disposed by contaminating the soil, air and water. Healthcare facilities are supposed to protect the health of people in their environment, not to be a creator of potential health hazard for them.
Furthermore, increase in patient turned-out has increase the generation of healthcare waste. Mboguwe, Mimereki and Magashula(2008) also reported that increase in population results to increase in healthcare facilities that lead to increased healthcare waste generation. It is expected that because of this increase, more attention should be paid to and priority given to proper healthcare waste management in Abeokuta South Local Government (ASLG). Management of healthcare waste continues to present an array of challenges especially as economic situation of the country deepen daily therefore, healthcare waste management has become a concern.
So many studies have been conducted on healthcare waste management but little or no work has been done concerning segregation of clinical waste which is a vital aspect in healthcare waste management (Coker, Sangodoyin, Sridhar, Booth, Olomolaiye, 2009). Segregation of waste is crucial in healthcare waste management because it is the first step in clinical waste management. Segregation of healthcare waste helps in reduction of the quantity of waste that is hazardous. Once healthcare waste are segregated, collection will be easy, proper storage will be done and disposal of infectious waste carried out in the way that it will not pose any harm to health workers, patients and the environment (WHO, 2014). Proper management of healthcare waste depends on good organization, sufficient funding and active participation of trained personnel. It was observed that healthcare facilities were not spending resources on clinical waste management Healthcare facility must allocate resources for colour coded bags and training of generator of healthcare waste for proper segregation and disposal for its sustainability. The intention of this study is to assess healthcare waste management practices at health facilities in Abeokuta South Local Government.
