Hospitals and health centers provide a variety of healthcare services and normally generate hazardous waste as well as general waste. General waste has a similar nature to that of municipal solid waste and therefore could be disposed of in municipal landfills. However, hazardous waste poses risks to public health, unless it is properly managed. The hospital waste management system encompasses many factors, i.e., number of beds, number of employees, level of service, population, birth rate, fertility rate, and not in my back yard (NIMBY) syndrome. Therefore, this management system requires a comprehensive analysis to determine the role of each factor and its influence on the whole system. In this research, a hospital waste management simulation model is presented based on the system dynamics technique to determine the interaction among these factors in the system using a software package, ithink. This model is used to estimate waste segregation as this is important in the hospital waste management system to minimize risk to public health. Real data has been obtained from a case study of the city of Nablus, Palestine to validate the model. The model exhibits wastes generated from three types of hospitals (private, charitable, and government) by considering the number of both inpatients and outpatients depending on the population of the city under study. The model also offers the facility to compare the total waste generated among these different types of hospitals and anticipate and predict the future generated waste both infectious and non-infectious and the treatment cost incurred.

Abstract. This paper describes the optimization study aimed to analyse the impact of the parameter describing the inflation rate on the cost of the system and its structure. The study was conducted on the example of the analysis of medical waste management system in north-eastern Poland, in the Podlaskie Province. The scope of operational research carried out under the optimization study was divided into two stages of optimization calculations with assumed technical and economic parameters of the system. In the first stage, the lowest cost of functioning of the analysed system was generated, whereas in the second one the influence of the input parameter of the system, i.e. the inflation rate on the economic efficiency index (E) and the spatial structure of the system was determined. With the assumed inflation rate in the range of 1.00 to 1.12, the highest cost of the system was achieved at the level of PLN 2022.20/t (increase of economic efficiency index E by ca. 27% in comparison with run 1, with inflation rate = 1.12).

“…Such positions can be exploited for monitoring, evaluation and change, if necessary. Existing models to investigate healthcare waste management structures employ techniques such as system dynamics [7], total quality management [8], life cycle analysis [9], etc. Few studies employing SNA on HWM can be found in the existing literature.…”

Comparing Administration of Hospital Wastes Using Social Network Analysis

Abstract. Waste management requires interaction between different players. It is important to map theses interactions to identify key players. This study utilizes social network analysis to compare the organization of waste management activities at two different hospitals. One of these hospitals was a large public hospital whereas the other one was a small private hospital. The structure and characteristics of the waste management network varied at both hospitals. On the whole the network at the larger hospital was institutional and the one at the smaller hospital was social in nature. At the larger hospital communication between any two members on average required three degrees of freedom. Moreover, its waste management network was characterized by the presence of three brokers whose absence could split the network into smaller disparate components. At the smaller hospital the waste management activities suffered from a lack of involvement from the paramedic staff. Thus its waste management network was more compact and communication between most of the network members did not require an intermediary. In both hospitals, a feedback mechanism between the municipal sanitary staff and hospital management was conspicuous by its absence. Hence issues such as an incidence of hazardous items mixed in the general waste could not be communicated to the hospital directly. The key positions identified in this study can be used for behavioral changes related to waste management among the concerned hospital staff.
