What is RTLS? Real Time Location Systems in Healthcare
Real-Time Location Systems (RTLS) in healthcare use IoT technologies like infrared, RFID, Wi-Fi, and BLE to track and manage the real-time location of patients, staff, and equipment within medical facilities, enhancing workflow efficiency, safety, and clinical quality by providing precise location data from broad presence detection to bed-level accuracy, which healthcare administrators analyze via integrated dashboards to improve operational performance and patient care.
Healthcare executives face ongoing challenges related to facility safety, staff satisfaction, quality of care, and workflow inefficiencies. Real-Time Location Systems (RTLS) are a technology solution designed to address these issues by providing real-time tracking and management of medical equipment, staff, and patients within healthcare environments. RTLS acts as an “indoor GPS” for hospitals, enabling improved workflow, cost reduction, and increased clinical quality through integration with other healthcare IT solutions.
What is RTLS in Healthcare?
RTLS uses badges or sensors attached to patients, staff, or equipment. Devices are positioned throughout the facility, emitting unique space IDs that are received by tags within those spaces. These tags communicate their location to a server via Wi-Fi, BLE, or dedicated networks, providing real-time and historical location data. Administrators can analyze this data through reports and dashboards to enhance operational efficiency, patient experience, and safety.
Types of RTLS Technologies
RTLS solutions leverage various IoT technologies, including infrared (IR), active RFID, Wi-Fi, Bluetooth Low Energy (BLE), and Low Frequency (LF). The level of location accuracy varies:
- Entry/Exit Point Locating: Uses LF technology to monitor movement through egress points and trigger alerts or automatic door locks.
- Presence-Based Locating: Determines if a tag is within a broad area, often using Wi-Fi or BLE.
- Room-Level Locating: Uses IR to pinpoint tags within specific rooms, useful for emergency assistance.
- Precise/Sub-Room Level Locating: Achieves bed or bay-level accuracy, enabling workflow automation and detailed analytics.
Estimation-based RTLS tracks at the unit or floor level, while Clinical-Grade Locating™ systems provide room, bed, and bay-level accuracy. Scalability and interoperability are important considerations when selecting an RTLS platform.
Managing and Maintaining RTLS
After implementation, system health must be managed. Platforms like CenTrak’s Connect Pulse™ help monitor device details, battery replacement, and troubleshooting.
Benefits of RTLS for Clinical Workflows
1. Supports Patient and Staff Safety
RTLS reduces risks such as equipment errors, infections, and physical threats. It integrates with security systems, access control, and mass notification systems. Examples include:
- Quick emergency alerts for staff
- Patient wander management
- Infant protection and mother/baby matching
- Hand hygiene compliance monitoring
- Automated contact tracing
- Locating equipment for recalls or maintenance
Staff Safety and Panic Alerting
RTLS enables staff to discreetly send panic alerts, instantly conveying their location to security teams for rapid response.
Infant Protection and Wander Management
RTLS systems protect infants and vulnerable patients by triggering alerts and locking doors if unauthorized movement is detected. Tamper sensors on infant bands provide additional security.
Infection Prevention and Control
RTLS automates hand hygiene compliance monitoring and contact tracing, providing accurate, real-time data to improve infection control and workflow.
2. Improves Patient Experience
RTLS enhances patient satisfaction by reducing confusion and delays. Digital wayfinding solutions offer real-time navigation and appointment reminders. Integration with patient infotainment systems keeps patients and families informed about care providers.
3. Streamlines Workflow
RTLS tracks patient flow, helping to identify and address bottlenecks such as long wait times, overcrowding, and delayed surgeries. Efficient workflows increase patient satisfaction and reduce stress for staff.
4. Reduces Cost with Analytics
RTLS provides data on equipment utilization, patient wait times, and length of stay, helping to reduce unnecessary expenditures. Accurate tracking prevents over-purchasing of equipment and optimizes resource allocation.
5. Mitigates Staffing Shortages
RTLS helps optimize existing resources in the face of staffing shortages by automating documentation, tracking assets, and providing actionable insights for decision-makers in critical departments like the OR, ICU, and ED.
How to Choose an RTLS Provider
When selecting an RTLS provider, consider:
- Vendor financial stability
- Clear objectives and long-term goals
- Compatibility with existing systems
- Adoption of the latest technology
- Cost and installation requirements
A strategic partner with a comprehensive solution suite simplifies future expansion and maximizes return on investment.
