The Role of Robots in Hospital Sanitation

Robots are becoming an integral part of our daily lives, with millions of Americans owning various types of robotic devices. In recent years, robots have ventured into the healthcare sector to improve cleanliness and prevent the spread of diseases. Hospital robots, such as Tru-D or “Trudy,” are revolutionizing sanitation practices, going beyond what traditional cleaners can achieve. This article explores the use of robots in hospital settings, particularly focusing on the Texas A&M Veterinary Medical Teaching Hospital (VMTH) and its adoption of Trudy.

Trudy, the stationary robot used at VMTH, utilizes 28 bulbs and eight ultraviolet C (UVC) centers to effectively eliminate even the most resilient infection-causing bacteria. Unlike conventional cleaners, Trudy targets bacteria that can persist for months on various surfaces in hospitals, including walls, floors, and tables. These persistent bacteria pose a significant risk, especially for patients who are already in a compromised state. Pam Douglas, the infection control coordinator at VMTH, recognizes the importance of sanitation in hospitals and actively advocated for the addition of Trudy to the existing protocols.

Manual sanitation in hospitals is an exhaustive and time-consuming process. It involves removing all equipment, cleaning the entire operating room, and meticulously reassembling everything. This process requires skilled technicians and takes approximately 30 minutes per room. However, with the introduction of Trudy, hospital staff can optimize their time and focus on other essential tasks, such as providing more attention to patients. Trudy can perform random cleanings of rooms, even when they have not been recently used, further enhancing the overall sanitation efforts.

Trudy’s appearance may resemble something out of science fiction, but its operation is surprisingly straightforward. Standing several feet tall, Trudy is cylindrical in shape and equipped with UVC lights that run vertically along its sides. Once placed in a room, Trudy’s 360-degree sensors assess the size of the space and determine the appropriate length of the disinfection cycle. For smaller rooms, the cycle lasts around 15-20 minutes, while larger rooms may require 30-40 minutes. While UVC disinfection robots are relatively common in human hospitals, veterinary hospitals, like VMTH, rarely utilize this advanced technology.

Since Trudy’s acquisition at VMTH earlier this year, it has been utilized over 800 times, testimony to its effectiveness and broad applicability. Trudy is deployed in various hospital spaces, ranging from operating rooms and exam rooms to isolation rooms and the intensive care unit (ICU) in both the large and small animal teaching hospitals. Its versatility enables comprehensive disinfection throughout the entire hospital, ensuring the highest standards of cleanliness are upheld.

Despite its sophisticated capabilities, Trudy can be easily operated after some training. Multiple personnel, in addition to the infection prevention department, are trained to handle Trudy efficiently. Controls for the robot are conveniently accessed through an iPad interface, making it user-friendly and accessible to a wider range of staff members.

Through the collaborative efforts of VMTH and Trudy, the hospital achieves elevated standards of infection control. While traditional cleaning methods are still employed, Trudy serves as a valuable enhancement that augments the efforts of hospital staff, benefiting not only patients but also staff, faculty, and the surrounding community. The combination of manual cleaning and Trudy’s automated disinfection contributes to a safer and healthier environment.

Robotic technology is revolutionizing hospital sanitation practices, and Trudy is at the forefront of this transformation. With its advanced disinfection capabilities, ease of operation, and extensive application in hospital settings, Trudy exemplifies the immense potential robots offer in improving hygiene and infection control. As this technology continues to evolve, it is likely that robots will become indispensable tools in maintaining cleanliness and preventing the spread of diseases in various healthcare settings.
