Digital Wristbands Enhance Detection of Infection Chains in Hospitals
In an innovative move to improve infection control, a hospital in Hanover has implemented digital wristbands equipped with Bluetooth technology to monitor and trace contacts among patients, staff, medical devices, and rooms. This technology aims to facilitate the rapid interruption of infection chains, particularly those involving multi-drug resistant pathogens, by providing comprehensive data on interpersonal and environmental contacts within the healthcare facility.
The system, currently active in the Siloah Hospital, involves the gradual distribution of Bluetooth transponders to both patients and employees. Medical equipment and hospital beds are also being equipped with these devices. With approximately 60 patients currently using the transponders, plans are in place to expand coverage to over 500 patients and 1,300 staff members during the initial rollout phase. The system may later be extended to additional hospitals within the regional healthcare network.
The infection control system operates by collecting anonymized data on interactions between individuals, equipment, and rooms. If an infection is detected, healthcare specialists can analyze the data to pinpoint potential sources and pathways of transmission. This enables targeted interventions, such as conducting screening tests on individuals who had contact with the infection source or implementing thorough disinfection protocols in affected areas.
According to hospital IT management, the software significantly improves the speed at which infection origins can be identified, compared to traditional manual tracking methods. This rapid response is crucial in preventing further spread, especially for pathogens known to survive on surfaces for extended periods.
The focus of the initiative is on healthcare-associated infections, particularly those caused by bacteria that can persist on surfaces and are commonly transmitted through direct contact. While the system is tailored to combat hospital-acquired infections, it is also adaptable for managing airborne viruses, such as those causing respiratory illnesses.
Patient privacy is a core component of the system. Movement data is pseudonymized and linked to specific individuals only if a credible suspicion of infection transmission arises. Strict controls ensure that only authorized personnel can access sensitive information, maintaining compliance with data protection regulations.
The adoption of digital tracking technology is especially significant for patients with compromised immune systems, who are more vulnerable to severe complications from infections. The rise of antibiotic-resistant bacteria presents a major challenge in healthcare settings, as such pathogens are difficult to treat and can lead to outbreaks if not quickly contained.
This project is backed by substantial federal funding under the Hospital Future Act, with a grant of three million euros supporting the implementation of the infection control system. The initiative reflects a broader trend toward digital transformation in healthcare, leveraging technology to enhance patient safety and improve clinical outcomes.
