Isansys Lifecare has launched a new medical system which allows a child or adult to be monitored wirelessly and continuously in real-time, ensuring any deterioration in the condition of a patient is identified more quickly and timely treatment is given.
The system, called the Patient Status Engine (PSE), uses wireless body-worn sensors to collect and analyse heart rate, respiration rate, heart rate variability, temperature, oxygen saturation and blood pressure as required.
This allows doctors and nurses to monitor patients better, more closely, more efficiently, and continuously. It also enables clinicians to use this automatically uploaded data to draw new insights and tailor care pathways to the needs of the individual patient.
Isansys Lifecare developed the product to try and ease the burden of care hospitals are now facing. With hospitals now busier than ever, the demands for improved and more efficient patient monitoring have also increased.
Today the number of patients per nurse continues to grow due to ever increasing patient numbers and relatively fewer nurses, and healthcare organisations globally – and particularly the NHS - now need to focus on improving efficiency and better resource utilisation in order to enable them to maintain their level of service.
The company noted that it is generally recognised that the effective use of appropriate digital and ICT technologies, together with the process improvements enabled by these technologies are the keys to tackling the increasing demand/limited resources challenges facing healthcare providers.
Among these are devices for directly ‘digitising’ the patient to provide continuous and real-time physiological and associated data, and wireless technologies that provide accurate, timely monitoring and enable quality patient care, whilst allowing caregivers and patients to roam freely throughout the hospital or even at home.
Keith Errey, CEO of Isansys, said: “Continuous, real-time monitoring has an important role to play in a ‘patient-focused’ healthcare system. At Isansys we have developed the PSE to provide clinicians with robust, accurate and relevant data which will give them new insights into their patient’s health, provide them with timely early warning indicators both in hospital and at home, and enable them to spend more time caring for their patients.”
Isansys first launched the PSE in 2013 and a second generation of the technology platform was introduced in November last year. The system’s hardware comprises wireless body-worn sensors, including the Isansys Lifetouch which provides continuous heart rate, respiration rate, heart rate variability, and on-demand ECG, and the Isansys Lifetemp, which measures continuous body temperature. The PSE currently uses third-party devices to collect data on oxygen saturation, PPG and blood pressure.
The data collected from the sensors is transmitted via Bluetooth to and displayed on a tablet-like device called the Patient Gateway, which also acts a data entry interface for the healthcare provider or the patient, if the latter is at home. Among its functions, the Gateway is used to identify and validate users, enter patient details, set early warning score thresholds and register sensor devices onto the network.
The Lifeguard Server is the PSE’s back-end IT system that collects the data from multiple Patient Gateways installed in and outside of hospitals, and then delivers the data directly to the care teams or to the patient on any browser enabled device, including smart phones and tablets.
“Vital signs are normally recorded every one to four hours onto paper charts, but the PSE collects precise, high resolution and continuous patient data and enables care teams, both in and out of the hospital to know the status of their patients better,” Errey explained.
“This allows clinical staff to see not only the current status of their patients at all times both in hospital and at home, but it also provides a view into the future status of their patients through data driven methods such as predictive algorithms and new physiologically based biomarkers. This enables a new proactive care paradigm to emerge rather than the current reactive methods currently in use.”
PSE in use at UK hospitals
Isansys is currently working with a number of health organisations in the UK and globally to help provide better care for patients in hospital and those recovering at home.
One of the studies is with the Royal Free Hospital, London, to demonstrate the PSE’s ability to replace lab-based tests with a new score calculated from the data captured by the Lifetouch. This newly developed data-driven biomarker provides real-time information on the level of deterioration of patients with advanced liver disease.
In another study, with the Queen Elizabeth Hospital, Birmingham, Isansys is working with the clinical team to use data from the PSE to develop an early warning score for patients who have undergone chemotherapy and are at high risk of sepsis. This ensures a more accurate prediction of a patient’s deterioration, which is expected to lead to faster and more targeted responses that can save lives and shorten hospital stays.
The PSE is also part of a project at the Birmingham Children’s Hospital aimed to predict deterioration in seriously ill children. Dr Heather Duncan, a consultant at Birmingham Children’s Hospital’s Paediatric Intensive Care Unit and leader of the project called RAPID (Real-time Adaptive & Predictive indicator of Deterioration) has hailed the system as a ‘game changer’ of healthcare.
She said: “This technology is truly transformational. It allows us to analyse many more patient’s data in real-time for the first time in the same way various other high-risk industries have done for years. The ability to track and identify deterioration towards a cardiac arrest will give doctors the chance to save the patient’s life. I genuinely believe this will change the way we care for patients in hospital forever.”
Isansys sees this technology as the future of how patients will be monitored, however the focus is not just on patient monitoring, it is about getting information in a digital context, which can then be used for a whole range of analytical techniques and methods to understand much more about human physiology and diseases.
