Hospital waste management in Ghana faces the risk of cross-contamination from the lack of thorough sorting of the waste at the points of generation, codisposal of hazardous and nonhazardous waste types, and use of open-fire pits and substandard incinerators for burning infectious waste. This has increased the potential for the spread of infections and chemical pollutants. A cross-sectional study was conducted in five hospitals in Ghana to assess behavioral patterns on waste sorting and the effectiveness of hospital waste management in Ghana. A total of 250 questionnaires were distributed purposively to some staff of the five hospitals to assess workers' perceptions on medical waste sorting and handling. Additionally, focused group discussions and transect walks were adopted to examine the current collection, storage, treatment, and disposal methods used in the health facilities. Chi-square analyses showed significant differences in waste-sorting behavior based only on occupation ( < 0.0001, =180) and not on gender, education, or experience in the health sector. Even though contaminated sharps were separated into brown safety boxes, color coding for other infectious waste containers was inconsistent across the health facilities. The study revealed that incineration is still the modal method of treatment in Ghanaian hospitals and therefore new approaches such as an engineering approach were required to minimize its environmental effects. It is recommended that periodic in-service training workshops be held for healthcare staff on the right source-segregation of medical waste, in order to facilitate the effective and safe handling, transport, treatment, and disposal of waste from health facilities.
加纳的医院废物管理面临交叉污染风险,原因包括在废物产生点缺乏对废物的彻底分类、危险废物和非危险废物类型的混合处置,以及使用明火坑和不合标准的焚化炉焚烧传染性废物。这增加了感染和化学污染物传播的可能性。在加纳的五家医院开展了一项横断面研究,以评估废物分类的行为模式以及加纳医院废物管理的有效性。总共向这五家医院的部分工作人员有目的地发放了250份问卷,以评估工作人员对医疗废物分类和处理的看法。此外,还采用了焦点小组讨论和横断面走访,以检查卫生机构目前使用的收集、储存、处理和处置方法。卡方分析表明,仅基于职业的废物分类行为存在显著差异(<0.0001,=180),而与性别、教育程度或在卫生部门的工作经验无关。尽管受污染的锐器被放入棕色安全箱中,但各卫生机构中其他传染性废物容器的颜色编码并不一致。该研究表明,焚烧仍是加纳医院的主要处理方法,因此需要采用工程方法等新方法来尽量减少其对环境的影响。建议为医护人员定期举办关于正确源头分类医疗废物的在职培训讲习班,以促进对卫生机构废物的有效、安全处理、运输、处理和处置。
