What Is RTLS?
In healthcare, a Real-Time Location System (RTLS) is a system used to provide immediate or real-time tracking and management of medical equipment, staff and patients within all types of patient care environments. While the technology differs from using location data captured by satellite trilateration, it can be thought of as a type of “indoor GPS” for hospitals. However, more so than just locating assets, accurate locating technology that easily integrates with other Healthcare IT solutions enables facilities to improve workflow, reduce costs and increase clinical quality. RTLS solutions comprise various tags and badges, technology platforms (Wi-Fi, Infrared, Bluetooth Low Energy, Low Frequency and others), hardware infrastructure (readers & exciters) and other components (servers, middleware & end-user software).
RTLS solutions typically include location sensors that are attached to various assets be it a patient, a staff member or a piece of equipment. Utilizing a unique ID, the system can locate the tags and give you real-time information about its positioning within the facility. Estimation-based RTLS solutions can enable tracking in a hospital’s unit or floor, whereas Clinical-Grade Locating™ systems are able to achieve room, bed, bay and even shelf-level tracking for true workflow automation.
Addressing Healthcare’s Needs
Hospitals face business issues similar to any other large organization. Automated monitoring and data intelligence gathering for the reporting and analysis of a facility’s processes allows healthcare executives and senior management to react quickly to — as well as prevent — obstacles related to items such as:
- Patient care
- Asset tracking
- Infection control
- Compliance reporting
- Increasing costs
- Readmission rates
- Nurse rounding
- Data collection
- Patient Throughput
- Equipment shrinkage
- Capital expenditures
- Staff shortages
RTLS: Promoting Patient and Staff Safety
Patient risks, including equipment errors, hospital-acquired infections or physical attacks are a constant threat within healthcare facilities. A Real-Time Location System can promote patient safety by reducing room for such risks. Examples of RTLS safety and security solutions provided by CenTrak Guardian™ include:
- The ability to keep a watchful eye on hand hygiene compliance.
- The ability to create contact tracing reports based on knowing when and which staff members and patients have come into contact with an infected person or asset.
- The ability for nurses and staff to call for help quickly in the event of an emergency or physical threat.
- The ability to detect when certain machines or systems are either part of an active recall or due for cleaning or maintenance.
- The ability to create alerts letting staff and nurses know if a patient has wandered into an area where they aren’t supposed to be. This is particularly crucial when caring for patients with dementia or Alzheimer’s.
- The ability to protect infants from abduction attempts as well as improper mother/baby matching using alerts and security system/door lock integrations.
A recent example of a hospital error that could have been prevented using RTLS solutions occurred at a hospital in Pasadena, California, in which 11 patients died due to infections from mismanaged duodenoscopes. They were not cleaned properly, and hospitals have to take a critical look at the reprocessing and storage of their duodenoscopes to prevent future infections. CenTrak’s Medical Scope Management Solution using a Clinical-Grade Real-Time Location System (RTLS) can automatically track and create alerts through every stage of this cleaning process. Staff immediately know when medical scopes need to be cleaned and are instantaneously notified of any possible infection risks.
RTLS Technology and Patient Satisfaction: Protecting the Bottom Line
RTLS technology can be particularly helpful not just for patient safety, but also for experience and satisfaction. Patient satisfaction has become increasingly more important since the Affordable Care Act tied Medicare reimbursements to patient satisfaction surveys. As of 2012 hospitals who did not do well on the surveys were at risk of losing 1% of the previous year’s payouts; in 2017, that risk is now 2%.
Tracking patient flow for throughput management can help recognize and address bottlenecks. Appropriate solutions can be tailored and monitored for common patient problems that lead to complaints, including:
- Long waiting times.
- Overcrowding in outpatient clinics, emergency rooms and post-anesthesia care units.
- Delayed or rescheduled surgeries.
- Not having enough beds for patients.
The fact of the matter is that hospital patients are in a near-constant state of motion. Between X-rays, moving around for rehabilitation purposes or switching between perioperative milestones, there is a lot of room for unnecessary delays or error. Departments that can operate more efficiently with real-time location information will be the ones to keep patients less stressed during their stay.
Integration to Support Strengthened Healthcare Analytics: Keeping Costs Down
RTLS can also help integrate your data systems and streamline information across the entire health system. This is especially helpful when considering hospital business processes. Examples of trends RTLS can help you measure include:
- Utilization rates for different pieces of hospital equipment to reduce rental needs and expenses
- Amount of time a patient waits for a particular service or to see a doctor
- How long the patient stays in the hospital
- Time spent with clinicians or elapsed time receiving other treatments
Integrating RTLS technology into hospitals can help cut down on unnecessary expenditures. One review, published in the International Journal of Health Geographics, projected that hospitals buy 10% to 20% more portable equipment than is needed for operational purposes, simply so that staff can find it when they need it.
Some items, perhaps most notably an ICU ventilator, come at a very high premium. Purchasing the optimal amount based on utilization, and having hospital RTLS keeping track of these machines can help reduce the number of asset redundancies. This can cut down on costs as well as save time for your clinicians when equipment is always where it should be.
RTLS Tags: Finding What and Who You Need at the Exact Moment You Need Them
Depending on how specific you need to be, different RTLS systems can give you various levels of accuracy. Sometimes all you need to know is whether or not a piece of equipment is on the right unit. In other instances, maybe you need to know whether a surgeon has made it to an operating room, or if a nurse is close to a patient who has requested assistance for urgent care. The hierarchy of location accuracy can include:
- Locating at entry or exit points: Using CenTrak battery-operated devices, you can determine the course of different tags as they move through entry or exit points.
- Presence-based locating: At this level, RTLS can determine whether or not a tag is within a certain parameter — normally a fairly wide net.
- Room-level locating: You can find out whether or not a tag is within the confines of a certain room. For example, in the event that a nurse must call for emergency assistance, RTLS can tell security personnel the exact room where the nurse is located.
- Sub-room level locating: Using RTLS you can tell exactly how much time a nurse spent in a room with a particular patient, or you can determine the location of a piece of equipment within that room. This is especially useful when you have rooms that are shared by multiple patients.
- Precise locating: In the hospital context, precise locating can find the exact tag location pinpointed on a detailed floorplan. Rapid location and condition updates are capable of accurately capturing interactions between equipment, patients and staff within seconds, facilitating the collection of clinical milestones and automating workflow.
RTLS Solutions and Staffing: Doing More With Less
Staffing shortages in hospital systems are becoming increasingly pronounced. For example, the 2015 Survey of Registered Nurses by AMN Healthcare revealed the fact that 62% of nurses older than 54 report they are considering retirement with the majority planning to do so within the next three years. Beyond nursing, the shortage problem persists across other essential hospital physicians, including operating room doctors, members of the neonatal department and the intensive care unit. Healthcare facilities have little choice but to address these shortages head-on by optimizing current resources while continuing to provide quality care.
A real-time location system for hospitals can help to mitigate the effects of the shortage and help hospital executives do more with less. Here is how RTLS can help in a few of the most critical areas of the hospital:
- Operating room. Automating events and documentation like tracking case status, milestones, patient location and department work queues can provide quick insights into the department. This reduces stress while improving efficiency. Surgical departments can also use RTLS to lower the amount of time dedicated to finding assets, which greatly optimizes staff utilization.
- Intensive Care Unit (ICU). Finding equipment and assets as quickly as possible in the ICU can quite literally be the difference between life and death. Staff members under pressure may not have enough time to locate needed assets. RTLS solutions like those offered by CenTrak, have the ability to pinpoint the exact location of needed resources with 100% accuracy. When clinicians can perform their jobs without being interrupted by misplaced equipment challenges, they enjoy a more seamless workflow. This can come with the bonus effect of increased job satisfaction.
