As robotics technology continues to advance, its role in our everyday lives is becoming more prominent. From cleaning robots to robotic lawn mowers, these devices are helping to simplify and streamline various tasks. One industry where robotics is making a significant impact is healthcare, specifically in hospitals. In recent years, hospitals have started incorporating robots into their sanitation protocols to ensure cleanliness and prevent the spread of infection. One such hospital that has adopted this technology is the Texas A&M Veterinary Medical Teaching Hospital (VMTH), where a stationary robot named “Trudy” uses ultraviolet C (UVC) light to kill bacteria and sanitize the environment.
Hospital robots, like Trudy, serve a different purpose than the robots commonly found in households. While cleaning robots, such as the popular Roomba, focus on tidying up living spaces, hospital robots are designed specifically for infection control. These robots employ UVC centers and multiple bulbs to eliminate even the most resilient bacteria that can linger on surfaces like walls, floors, and tables. This is crucial in preventing the spread of infection-causing bacteria, as certain strains can survive for months, even after traditional disinfectants have been applied.
Sanitation plays a vital role in hospitals where patients may be more susceptible to infections. Pam Douglas, infection control coordinator at the VMTH, recognizes the importance of maintaining a clean environment to protect not only the animals but also the staff and visitors. Having witnessed the effectiveness of UVC robots during her time as a registered nurse in human hospitals, Douglas advocated for the VMTH to incorporate Trudy into their existing sanitation protocols.
While manual cleaning is effective, it requires a considerable amount of time and effort. Katy Wendler, the assistant hospital administrator overseeing the VMTH’s operating rooms, explains the extensive process involved in manually cleaning an operating room. Every piece of equipment is removed, the entire base of the operating room is cleaned, and each item is meticulously cleaned before being put back. Although this thorough process is necessary, it consumes valuable time and energy. With the introduction of Trudy, hospital staff can now focus on other tasks, such as spending more time with patients, while still maintaining a high level of cleanliness.
Trudy, although stationary, resembles something from science fiction with its tall cylindrical structure and vertical UVC lights. Once placed in a room, its 360-degree sensors determine the size of the space and the appropriate duration for the disinfection cycle. Smaller rooms may require a 15-20 minute cycle, while larger rooms could take 30-40 minutes. While UVC disinfection robots are common in human hospitals, veterinary hospitals are only just beginning to adopt this technology. Since the VMTH acquired Trudy at the beginning of the year, it has been used over 800 times in various areas, including operating rooms, exam rooms, isolation rooms, and ICU in both the large and small animal teaching hospitals.
One might assume that operating a cutting-edge disinfection robot like Trudy would require specialized training. However, the process is straightforward, making it accessible for anyone after some initial training. Douglas highlights that many staff members, not just those in infection prevention, have been trained to operate Trudy. All controls are conveniently accessible via an iPad interface, making it user-friendly for all.
Trudy, in partnership with the VMTH, is working tirelessly to maintain the highest standards of infection control. While manual cleaning remains an integral part of the sanitation process, Trudy enhances the efforts of the hospital by allowing for random cleanings of rooms, even if they have not been recently occupied. This constant vigilance helps to ensure that the hospital environment remains as clean and safe as possible for patients, staff, faculty, and the wider community.
The incorporation of robotics into hospital sanitation protocols is revolutionizing the way hospitals maintain cleanliness and prevent the spread of infection. The Texas A&M Veterinary Medical Teaching Hospital’s implementation of Trudy, a stationary UVC disinfection robot, showcases the effectiveness and efficiency of this technology. With Trudy’s assistance, the hospital can allocate more time to patient care while still adhering to rigorous cleanliness standards. The role of robotics in infection control is rapidly evolving, and it is safe to say that their presence in healthcare settings will only continue to grow.
