Reducing Healthcare-Associated Infections through Proper Waste Disposal: The Arusha Health Center Incinerator Experience in Rwanda
Healthcare-associated infections (HAIs) are a significant concern in healthcare facilities worldwide, particularly in low- and middle-income countries where resources are limited. In Rwanda, the Arusha Health Center has taken a proactive approach to reducing HAIs through the implementation of a proper waste disposal system, specifically an incinerator. This news highlights the importance of proper waste disposal in reducing HAIs and shares the experience of the Arusha Health Center in Rwanda.
The Burden of Healthcare-Associated Infections
HAIs are infections that patients acquire during the course of receiving treatment for other conditions. These infections can be caused by a variety of factors, including poor hygiene, inadequate cleaning and disinfection of equipment and surfaces, and improper waste disposal. According to the World Health Organization (WHO), HAIs affect hundreds of millions of patients worldwide each year, resulting in significant morbidity, mortality, and economic burden.
The Role of Proper Waste Disposal in Reducing HAIs
Proper waste disposal is a critical component of infection prevention and control in healthcare facilities. Medical waste, including infectious and hazardous materials, must be handled and disposed of in a way that minimizes the risk of transmission of diseases. The WHO recommends that healthcare facilities implement a waste management system that includes segregation, storage, transportation, and disposal of waste.
The Arusha Health Center Incinerator Experience
The Arusha Health Center, located in Rwanda, has been at the forefront of implementing a proper waste disposal system to reduce HAIs. In 2018, the health center installed an incinerator, which has significantly improved the management of medical waste. The incinerator is designed to burn medical waste at high temperatures, effectively destroying pathogens and reducing the risk of infection transmission.
Prior to the installation of the incinerator, the health center faced significant challenges in managing medical waste. Waste was often disposed of in a haphazard manner, with little attention to segregation or proper handling. This led to a high risk of infection transmission among patients, healthcare workers, and the surrounding community.
Impact of the Incinerator on HAI Reduction
The introduction of the incinerator at the Arusha Health Center has had a significant impact on reducing HAIs. A study conducted by the health center found that the incidence of HAIs decreased by 30% in the first year after the incinerator was installed. This reduction is attributed to the proper management of medical waste, which has minimized the risk of infection transmission.
Additionally, the incinerator has also improved the overall hygiene and sanitation of the health center. The reduced accumulation of medical waste has created a cleaner and safer environment for patients and healthcare workers, which is essential for preventing HAIs.
Challenges and Lessons Learned
While the introduction of the incinerator has been successful in reducing HAIs, there have been challenges along the way. One of the main challenges faced by the health center was the initial cost of installing the incinerator. However, the long-term benefits of reducing HAIs and improving patient safety have far outweighed the costs.
Another challenge was the need for ongoing training and education of healthcare workers on proper waste management and handling. The health center has had to invest in training programs to ensure that staff understand the importance of proper waste disposal and how to use the incinerator correctly.

The Arusha Health Center incinerator experience in Rwanda highlights the importance of proper waste disposal in reducing HAIs. The introduction of the incinerator has significantly improved the management of medical waste, reducing the risk of infection transmission and creating a cleaner and safer environment for patients and healthcare workers. While there have been challenges along the way, the benefits of reducing HAIs have far outweighed the costs. This experience serves as a model for other healthcare facilities in low- and middle-income countries, demonstrating the critical role of proper waste disposal in preventing HAIs and improving patient safety.
Recommendations
Based on the experience of the Arusha Health Center, several recommendations can be made:
- Invest in proper waste disposal systems: Healthcare facilities should prioritize the installation of proper waste disposal systems, including incinerators, to minimize the risk of HAIs.
- Provide ongoing training and education: Healthcare workers should receive regular training and education on proper waste management and handling to ensure that they understand the importance of proper waste disposal.
- Monitor and evaluate HAI rates: Healthcare facilities should regularly monitor and evaluate HAI rates to assess the effectiveness of their waste management systems and identify areas for improvement.
- Collaborate with stakeholders: Healthcare facilities should collaborate with stakeholders, including government agencies, international organizations, and community leaders, to raise awareness about the importance of proper waste disposal and to secure funding and support for waste management initiatives.
By following these recommendations, healthcare facilities in low- and middle-income countries can reduce the burden of HAIs and improve patient safety, ultimately saving lives and reducing the economic burden of these infections.
