vHDU Phase 5: Impact of an Ambulatory Monitoring System on Deterioration Detection and Clinical Outcomes

United Kingdom240 participantsStarted 2022-07-28

Plain-language summary

Sometimes in hospital, it is not noticed that patients are becoming unwell quickly enough. This may mean that they are less likely to survive than if the worsening of their illness had been picked up sooner. One reason for this may be that hospital staff are unable to check patients' vital signs (such as breathing rate, heart rate and level of oxygen in their blood) frequently enough to help them decide if a patient is becoming more unwell. Currently, for nurses to watch these vital signs closely, patients are either attached to a static machine by the patient's bedside using wires, or staff visit the patient every few hours to measure these vital signs using a portable wired machine. It is now possible to closely monitor patients using small devices which attach to the wrist, finger or chest. These devices allow nursing staff to continually watch vital signs data from these patients when they are away from their bedside. These machines are also wireless and portable, so they do not stop patients moving around, which is important for recovery, and are comfortable to wear. In past years, the investigators have tested these devices and developed a system to allow the clinical staff to see the continuous vital signs. In this final stage of the project, the investigators will test this system (with the selected devices) on patients in hospital. The investigators will start by doing a small trial on one surgical ward, and asking for staff and patient feedback of how the system worked, how useful it was, and how easy to use. If the feedback from this first small trial is positive, the investigators will conduct a future trial in several hospitals, to test how useful the system is in improving patient recovery.
