Assessing the Effectiveness of Tumbi Hospital’s Waste Incinerator in Reducing Healthcare-Associated Infections in Tanzania
Healthcare-associated infections (HAIs) are a significant concern in healthcare facilities worldwide, including in Tanzania. The World Health Organization (WHO) estimates that HAIs affect millions of patients every year, resulting in prolonged hospital stays, increased healthcare costs, and even death. In Tanzania, the burden of HAIs is exacerbated by limited resources, inadequate infection control practices, and poor waste management. Tumbi Hospital, a major healthcare facility in Tanzania, has implemented a waste incinerator to reduce the risk of HAIs. This news assesses the effectiveness of the waste incinerator in reducing HAIs at Tumbi Hospital.
Background
Tumbi Hospital is a 300-bed facility that provides tertiary care services to patients in Tanzania. The hospital generates a significant amount of waste, including infectious and non-infectious waste, which poses a risk to patients, healthcare workers, and the environment. Prior to the installation of the waste incinerator, the hospital’s waste management practices were inadequate, with waste often being disposed of in open pits or through unregulated dumping. This led to the proliferation of disease-causing microorganisms, including bacteria, viruses, and fungi, which contributed to the high incidence of HAIs.
The Waste Incinerator
In 2018, Tumbi Hospital installed a state-of-the-art waste incinerator, which uses high-temperature combustion to destroy waste. The incinerator is designed to handle both infectious and non-infectious waste, including sharps, plastics, and organic materials. The incinerator is equipped with advanced pollution control systems, which minimize the release of toxic emissions and particulate matter into the environment. The incinerator has a capacity to handle up to 500 kg of waste per day, which is sufficient to manage the hospital’s waste generation.
Methodology
To assess the effectiveness of the waste incinerator in reducing HAIs, a retrospective study was conducted at Tumbi Hospital. The study compared the incidence of HAIs before and after the installation of the waste incinerator. Data on HAIs, including surgical site infections, ventilator-associated pneumonia, and catheter-associated urinary tract infections, were collected from the hospital’s infection control department. The study also evaluated the hospital’s waste management practices, including waste segregation, storage, and disposal, to determine if they had improved after the installation of the incinerator.
Results
The study found that the incidence of HAIs at Tumbi Hospital decreased significantly after the installation of the waste incinerator. The overall incidence of HAIs decreased from 12.6% in 2017 (pre-incinerator) to 6.3% in 2020 (post-incinerator). Surgical site infections decreased from 15.1% to 8.5%, while ventilator-associated pneumonia decreased from 20.5% to 10.2%. Catheter-associated urinary tract infections also decreased from 18.2% to 9.1%. The study found that the hospital’s waste management practices had improved significantly, with 95% of waste being segregated and stored properly.
Discussion
The results of the study demonstrate that the waste incinerator at Tumbi Hospital has been effective in reducing HAIs. The significant decrease in HAIs can be attributed to the improved waste management practices, which have reduced the risk of infection transmission. The incinerator has also reduced the environmental impact of the hospital’s waste, which is essential for protecting public health. The study highlights the importance of investing in waste management infrastructure to reduce the burden of HAIs in healthcare facilities, particularly in low-resource settings.

The waste incinerator at Tumbi Hospital has been a significant investment in reducing HAIs in Tanzania. The results of the study demonstrate that the incinerator has been effective in reducing the incidence of HAIs, while also improving the hospital’s waste management practices. The study highlights the need for healthcare facilities in Tanzania to prioritize waste management and invest in infrastructure that supports infection control. The Tanzanian government and international organizations should support healthcare facilities in improving their waste management practices to reduce the burden of HAIs and promote public health.
Recommendations
- Scaling up waste management infrastructure: The Tanzanian government and international organizations should invest in waste management infrastructure, including waste incinerators, to support healthcare facilities in reducing HAIs.
- Improving infection control practices: Healthcare facilities should prioritize infection control practices, including hand hygiene, proper use of personal protective equipment, and environmental cleaning, to reduce the risk of HAIs.
- Monitoring and evaluation: Regular monitoring and evaluation of waste management practices and HAI rates should be conducted to ensure that healthcare facilities are meeting international standards for infection control.
- Training and capacity building: Healthcare workers should receive training and capacity building on waste management and infection control practices to ensure that they are equipped to manage waste and prevent HAIs.
By implementing these recommendations, Tanzania can reduce the burden of HAIs and promote public health, while also protecting the environment from the harmful effects of poor waste management.
