The Internet of Things (IoT) is a concept in which physical objects equipped with tiny sensors communicate with the surrounding world via the Internet. These physical entities transmit a constant flow of information that can help form the basis for better decisions. For example that a particular hospital bed needs cleaning.

This kind of decision-making support is very much in demand in hospitals, because it can help optimise workflows. The sensors and equipment now widespread in hospitals – increasingly Internet-driven – are what makes this possible.

It is therefore important that hospitals ensure that their IT solutions are future-compatible, so they are not cut off from exploiting the opportunities that lie in being able to access and use the large amounts of data from the physical world that are now available from many hospital systems. 



By using the Columna Internet of Things platform, the individual applications are decoupled from any particular tracking technologies and Internet-controlled sensors and equipment. The advantage of this is that the individual hospital can thus choose to replace or add equipment and tracking technologies, without no significant challenges in relation to how the applications work.

CSL Hospital Overview With Platform UK

The Information Bus is an IT platform that is ideal for gathering tracking data from several tracking technologies and communicating this data to relevant applications. The Information Bus collects all of the data that is tracked at the hospital. Individual applications can then tap into the necessary data from the Information Bus and share the information between applications.

The platform is built to collect the large amounts of data that the physical objects transmit about ongoing events. The data is decoded and enriched with basic data about the objects, such as location, name, status, etc. This makes the data more accessible, understandable and usable by a wide range of different software and apps, which in turn gives the user the right information and decision-making support.

The collection of data and the subsequent display of such data are carried out by using the globally recognised EPCIS standard, which is a common language for identifying subjects.

The Columna IoT Platform consists of four basic elements: 

  1. An integration and identity system that receives events from the “real world” and then enriches events with master data, before disseminating the information to other IT systems.A location database that contains a precise description of relevant locations inside and outside the hospital.
  2. A location database, which contains unambiguous, consistent descriptions of relevant locations inside and outside the hospital.
  3. A route calculator that can calculate routes from A to B in the hospital, both indoors and outdoors. This is needed for things like calculating  “shortest distances” between any two points.
  4. 4. A database for storing historical data about where things and people have moved. This data can be made anonymous, so as not to identify individuals.

The Columna Internet of Things platform is a key element in Columna Service Logistics, and a prerequisite for the solution working appropriately and ensuring maximum value from the applications in the hands of users.

It is this element that helps ensure each application works consistently and can easily be integrated with others, and is also crucial to flexible choices about the tracking technology used in any particular hospital.
