With Operational Intelligence, your people and things are automatically sensed as they move and interact in different places. Rules can be set up to change status for process time-stamping, distribute reminder tasks, update map views, and even email family members as patients move through surgery. Data from InSites can provide location and duration context to other tools, like EHRs and ERPs. Data from other systems can feed into InSites to enhance reporting and analytics.
As people and things move around your facilities, InSites is building up stores of intelligence about your operations that you’ve never had before. Intelligence that isn’t gathered by hand. Intelligence that gives you clear paths to continuously make things better.
For most, the word platform is just a buzzword. For us, it’s core to how we’ve built our solution from the start, it’s central to our strategy and vision, and it’s the foundation of our customers’ success. Everything about our platform is open and accessible through RESTful APIs, providing a flexible, scalable “future proof” solution for healthcare systems and an open development environment for building new apps and sharing data across the enterprise.
Financial and Operational Efficiency
Optimize inventory, increase asset utilization, reduce rental expenses, and streamline workflows to increase patient throughput – resulting in decreased cost and increased revenue and reimbursement.
Deliver better care through real-time high-impact information. Know where your patients are in the process of care delivery and be aware of situations that may cause harm to a patient. Track surgical instruments and monitor exposure to infection diseases to reduce your liability exposure and create a safer care environment.
Automate your monitoring processes to meet state, federal, and Joint Commission regulations – from monitoring the location and status of oxygen tanks and fire extinguishers to the temperature of vaccine storage and blood refrigerators.
Satisfaction of Patients, Families, and Staff
Increase the time that your nurses can spend with patients by automating tedious, manual activities – improving the patient experience and increasing staff satisfaction. Provide patient families with automated up-to-date information on the status of their loved ones. Improve Medicare reimbursement through increased patient satisfaction scores.
RLS / Asset Management / Real-Time Locating Systems (from Wikipedia 2011)
Real-time locating systems (RTLS) are used to track and identify the location of objects in real time. Using simple, inexpensive badges or tags attached to the objects, readers receive wireless signals from these tags to determine their locations. RTLS typically refers to systems that provide passive or active (automatic) collection of location information.
Location information usually does not include speed, direction, or spatial orientation. These additional measurements would be part of a navigation, maneuvering or positioning system.
The term RTLS was created (circa 1998) to describe an emerging technology that not only provided the Automatic Identification capabilities of active RFID tags, but added the ability to see the physical location of the tagged asset on a computer screen. Although this capability had been utilized previously by military and government agencies, the technology had been too expensive for commercial purposes.
By the early 1990's, commercialization began at two healthcare facilities in the United States (Foote Hospital in Jackson, MI and Broward Children's Hospital in Pompano Beach, FL). These early adoptors are atrributed to real-time locating industry innovator Precision Tracking (Versus Technology, Inc.) and were based on the transmission and decoding of infrared light signals from actively transmitting tags.
RTLS excludes passive RFID indexing (radio frequency transponder indexers) and Cellnet base station segment locators (location-based services) from the scope of the ISO/IEC approach to RTLS standardization as well as all beacon systems, that ping without request. RTLS systems apply typically in confined areas, where the required reference points would be equipped with wireless anchor nodes.
Ranging, as a special term for measuring distance, is the prerequisite for locating. Measuring a bearing angle, i.e. angulating is the other alternative.
Determining the distance may be either a non cooperative scanning process, as with RADAR or LIDAR, or a cooperative direct distance measuring process, as with RTLS. A scanned beam may form an overall image as a model of the whole scene. In all other cases the image of the scene is rather selective.
The following step is extracting the distance information from the scanned image. Direct distance measurement with a single beam targets only the object to be measured, for example, with a laser. This method requires additional information about the direction of the beam. The remaining method is omni-directional transmission with a signal containing an address code. Only the addressed object responds to the request. The time required for the signal to reach the object can be used to calculate the distance. After completing the distance measurement, the location may be computed.
There are two different principles when measuring travel time of radio waves:
- Trilateration derives the travel time of a radio signal from a metering unit, and measures and computes the distance with the relation of light speed in vacuum, the (Time of arrival concept).
- Triangulation derives the travel time of a pair of synchronous radio signals from a metering unit with two transmitters, and measures and computes the difference of distance with the relation of light speed in vacuum as an angle versus the baseline of the two transmitters (TDOA time difference of arrival concept).
All the terms named here just apply to measurement concepts. All information about location is for services applied to mobile or portable or otherwise transportable objects. Location information may be relevant for managing interaction of persons with services as well.

Types of technologies used
There is a wide variety of systems concepts and designs to provide real-time locating. A good choice is listed in RTLS for Dummies by Ajay Malik (Wiley 2009). Methods include:
-- Active radio frequency identification (Active RFID)
-- Active radio frequency identification - infrared hybrid (Active RFID-IR)
-- Infrared (IR)
-- Optical locating
-- Low-frequency signpost identification
-- Semi-active radio frequency identification (semi-active RFID)
-- Radio beacon
-- Ultrasound Identification (US-ID)
-- Ultrasonic ranging (US-RTLS)
-- Ultra-wideband (UWB)
-- Wide-over-narrow band
-- Wireless Local Area Network (WLAN, Wi-Fi)
-- Clustering in noisy ambience
-- Bivalent systems
A general model for selection of the best solution for a locating problem has been constructed at the Radboud University of Nijmegen. Many of these references do not comply with the definitions given in international standardization with ISO/IEC 19762-5 and ISO/IEC 24730-1. However, some aspects of real-time performance are served and aspects of locating are addressed in context of absolute coordinates.
