An Analysis of the Biomedical Waste Management Challenges at Chawama Level 1 Hospital in Lusaka District of Zambia
This study reveals that biomedical waste management at Chawama Level 1 Hospital in Zambia is severely compromised by interconnected institutional weaknesses, including inadequate infrastructure, insufficient staff training, and low policy awareness, which collectively result in poor segregation compliance and necessitate a comprehensive strategy involving policy reinforcement, capacity building, and resource investment.

Every day, hospitals generate a unique kind of trash: materials used to treat patients, from bandages and syringes to gloves and test tubes. When this biomedical waste is handled correctly, it is safely contained and destroyed. But when it is mixed with ordinary household refuse or left exposed, it becomes a dangerous vector for disease, capable of spreading infections like HIV or hepatitis to healthcare workers, waste collectors, and the surrounding community. In wealthy nations, sophisticated systems and advanced technology manage this hazard. In many lower-resource settings, however, the system often breaks down due to a lack of money, training, or equipment. The question is not just whether waste is being thrown away, but whether the people doing the throwing know how to do it safely, have the tools to do so, and are supported by a system that makes safety the default.
A recent investigation at Chawama Level 1 Hospital in Lusaka, Zambia, offers a clear look at how these systems function—or fail—in a busy urban clinic. The researchers, Lydia Chisenga and Chileleko Mapiki, set out to understand why biomedical waste management remains a challenge there, despite the existence of national rules and guidelines. They focused on three specific areas: the institutional side, which includes policies and supervision; the infrastructural side, covering physical tools like bins and protective gear; and the operational side, which looks at how staff actually perform their daily tasks. By speaking with 54 healthcare workers and watching waste handling in action, they mapped the gap between what is supposed to happen and what actually occurs on the ground.
The study began by listening to the people who do the work. The team interviewed doctors, nurses, cleaners, and waste handlers, asking them about their training, their knowledge of hospital rules, and the resources available to them. They also spent ten days observing the hospital's departments, watching how waste was sorted and stored in real time. The results painted a picture of a system strained by interconnected weaknesses. While the hospital has a policy on waste management, only about half of the staff knew it existed. Even fewer had received formal training on how to handle hazardous materials, and only a third reported that supervisors regularly checked their work. This lack of institutional support created a ripple effect: without clear guidance or oversight, staff confidence in their ability to handle waste safely remained low.
The physical environment presented its own set of hurdles. The researchers found that the majority of staff reported a shortage of color-coded bins, which are essential for separating infectious waste from general trash. Without these distinct containers, different types of waste get mixed together, turning harmless refuse into a potential health hazard. Similarly, personal protective equipment, such as gloves and masks, was not consistently available, leaving workers exposed to risk. Storage facilities for the waste were also described as insufficient, leading to piles of untreated waste waiting for disposal. The data showed a direct link between these missing tools and poor performance: where bins were available, staff were more likely to sort waste correctly. Where they were missing, proper segregation fell apart.
When the researchers looked at the actual behavior of the staff, the numbers were stark. Only about one-quarter of the workers demonstrated proper segregation of waste, meaning the vast majority were not following the correct procedures. Observations confirmed this, showing that in only 35 percent of the cases watched, waste was sorted according to safety standards. The study found that the difference between good and bad practices was not random; it was tied to specific factors. Staff who had received training were more confident in their work. Those who knew the hospital's policies were more likely to follow them. And crucially, those who were regularly supervised by managers were far more likely to adhere to safety protocols. The presence of a supervisor made a measurable difference in whether the rules were followed.
The authors conclude that the problems at Chawama Level 1 Hospital are not isolated incidents but a result of a system where institutional gaps, resource shortages, and operational inefficiencies reinforce one another. A lack of training leads to confusion, which is compounded by a lack of bins and protective gear, all while weak supervision allows unsafe habits to continue. The study suggests that fixing this requires a comprehensive approach rather than a single solution. It calls for mandatory training for all staff, better communication of hospital policies, and a dedicated budget to ensure that essential equipment like color-coded bins and protective gear is always in stock. Most importantly, it highlights the need for consistent supervision to ensure that safety rules are not just written down but practiced every day.
This research underscores that safe waste management in a hospital is not just about having a plan; it is about having the people, the tools, and the oversight to make that plan work. In a setting like Chawama, where resources are tight and patient loads are high, the margin for error is small. The findings provide a clear roadmap for improvement, showing that when staff are trained, equipped, and watched over, they can overcome the barriers that currently put their community at risk. The path forward involves strengthening the entire system, from the policy written in an office to the bin placed in a ward, ensuring that the safety of patients and workers is never left to chance.
