Plain English summary of protocol
Background and study aims:
To help doctors and nurses recognise when patients are becoming unwell, they are monitored in hospital by an Early Warning System called Track & Trigger. Each time clinical measurements (for example pulse, blood pressure, temperature and the bodys oxygen levels) are recorded, they are compared to a scale and given a number that represents the position on the scale. If the number is too high, the nurse at the bedside will respond by asking for help from a doctor or more senior nurse. Everyone is compared against the same scale and we do not know if this is the best way to monitor patients during their hospital stay. This study is designed to investigate whether it is possible to create a personalised monitoring programme for patients who are discharged from the Intensive Care Unit.
The aim of the study is to link information from a patients stay in the intensive care unit with measurements taken during their hospital stay after discharge from intensive care. We will use this information to programme an automatic alerting calculation that will be different for each patient. We want to test whether this new system will improve nurses and doctors abilities to watch over patients and if it might also alert them earlier to a patient who may be in need of more treatment, a different type of care, or more or less monitoring.
Who can participate?
Patients who are being discharged from the intensive care units at the Oxford University Hospitals NHS Trust and the Royal Berkshire NHS Foundation Trust.
What does the study involve?
Before patients leave the intensive care unit, or shortly after they arrival on their new ward, the study monitoring equipment will be attached to them. This involves attaching some sticky dots to their chest which will connect leads from the patient to the monitor so that their heart rate can be recorded. Patients will also be asked to wear a device that will measure the levels of oxygen in their blood.
Patients in the study will be visited by research nurses once or twice each day while they are wearing the monitoring equipment. The nurses will check that it is recording correctly and that there are no problems. They will also look at the patients medical notes and will record information about them and the treatment they are given during their hospital stay. Patients will be asked to wear the monitor until they are discharged from hospital. However, if they are still in hospital fourteen days after they have been discharged from the intensive care unit, we will remove the monitor.
What are the possible benefits and risks of participating?
This study may help us in the future to improve the standard of care for patients who are at risk of developing health problems after their stay in the intensive care unit. We hope that the information we collect from patients about their stay in hospital will allow us to treat future patients faster and perhaps save lives. There are no known risks associated with taking part in this trial.

| Scientific title | Post-Intensive Care Risk-adjusted Alerting and Monitoring - an observational study |
| Study acronym | PICRAM 2 |
| Study objectives | Patients discharged from intensive care units (ICU) have a very high risk of subsequently deteriorating on hospital wards. PICRAM will develop ways of alerting clinicians to these deteriorations early. After ICU discharge, there is little information available about the normal course which patients vital signs follow if they are safely discharged from hospital. Using an ambulatory monitor we plan to continuously record vital signs from up to 500 patients who have spent more than three days in ICU from 2 hospitals (one teaching hospital Oxford University Hospitals NHS Trust one large district general hospital The Royal Berkshire NHS Trust). We will also recover vital signs from the 72 hours leading up to discharge from the ICU, (recorded in the standard clinical electronic database). These two sets of data will allow us to understand the patterns by which patient recovery is displayed in vital signs. We will develop ways by which clinicians can be alerted to patients who are not following these patterns of recovery, as these patients will be at greater risk of deterioration. Finally, we will recover data from the patients ICU stay. We have developed a large anonymised database from the standard clinical electronic databases of the two Intensive Care Units. We are using this to design tools to help clinicians recognise which patients are at risk of deterioration after discharge from intensive care. We will use data from the Intensive Care Unit stay of the patients whose vital signs we record after intensive care discharge to work out how best to merge the data from their time in Intensive Care with the vital signs recovery patterns to best identify patients who are deteriorating after ICU discharge. The use of prolonged ambulatory vital sign monitoring in post-intensive care patients is relatively novel. We will therefore record patients views on the wearability of the system and data on the functionality of the system. |
