Healthcare waste comprises all wastes generated at healthcare facilities, medical research centers and laboratories. Although 75-90% of these wastes are classified as household waste posing no potential risk, 10-25% are deemed to be hazardous, representing a potential threat to healthcare workers, patients, the environment and even the general population, if not disposed of appropriately. If hazardous and non-hazardous waste is mixed and not segregated prior to disposal, costs will increase substantially. Medical waste management is a worldwide issue. In Iran, the majority of problems are associated with an exponential growth in the healthcare sector together with low- or non-compliance with guidelines and recommendations. The aim of this study was to reduce the amounts of infectious waste by clear definition and segregation of waste at the production site in Namazi Hospital in Shiraz, Iran.
Namazi Hospital was selected as a study site with an aim to achieving a significant decrease in infectious waste and implementing a total quality management (TQM) method. Infectious and non-infectious waste was weighed at 29 admission wards over a 1-month period.
Before the introduction of the new guidelines and the new waste management concept, weight of total waste was 6.67 kg per occupied bed per day (kg/occupied bed/day), of which 73% was infectious and 27% non-infectious waste. After intervention, total waste was reduced to 5.92 kg/occupied bed/day, of which infectious waste represented 61% and non-infectious waste 30%. The implementation of a new waste management concept achieved a 26% reduction in infectious waste.
A structured waste management concept together with clear definitions and staff training will result in waste reduction, consequently leading to decreased expenditure in healthcare settings.
医疗废物包括在医疗保健机构、医学研究中心和实验室产生的所有废物。尽管这些废物中有 75-90%被归类为不会造成潜在风险的家庭废物,但仍有 10-25%被认为是危险废物,对医护人员、患者、环境甚至普通人群构成潜在威胁,如果处理不当的话。如果在处理之前将危险废物和非危险废物混合在一起且未进行分类,那么成本将大幅增加。医疗废物管理是一个全球性问题。在伊朗,大多数问题与医疗保健部门的指数级增长以及低合规或不合规的指导方针和建议有关。本研究的目的是通过在伊朗设拉子的 Namazi 医院生产现场明确界定和分类废物,减少感染性废物的数量。
Namazi 医院被选为研究场所,旨在显著减少感染性废物并实施全面质量管理(TQM)方法。在一个月的时间内,对 29 个入院病房的感染性和非感染性废物进行称重。
在引入新的指南和新的废物管理概念之前,每个占用床位每天的总废物重量为 6.67 公斤(kg/occupied bed/day),其中 73%为感染性废物,27%为非感染性废物。干预后,总废物减少到 5.92kg/occupied bed/day,其中感染性废物占 61%,非感染性废物占 30%。实施新的废物管理概念可将感染性废物减少 26%。
结构化的废物管理概念以及明确的定义和员工培训将导致废物减少,从而降低医疗保健机构的支出。
