VRES Study in Two Phases to Monitor Cardiac Surgical Patients Following Discharge From ICU
VRES Study in Two Phases to Monitor Cardiac Surgical Patients Following Discharge From ICU
Failure to recognise deterioration early is a major cause of preventable deaths amongst
 hospital patients. The investigators wish to study whether continuous monitoring of 'vital
 signs' (pulse rate, breathing rate, and blood oxygen saturations) with computer modeled
 alerting to detect patient deteriorations can reduce cardiac arrest rate and critical care
 readmissions from the wards by alerting staff to clinical deteriorations more effectively
 than current paperbased systems.

 Continuous monitoring of 'vital signs' can be achieved in two ways. Continuous monitoring of
 'vital signs' has traditionally been restricted to the bedside because of the need for the
 patient to be connected by wires to the monitor.

 More recently, advances in telemetry (wireless technology) have allowed the development of
 wearable devices which allow patients to mobilise freely, whilst constantly monitoring these
 'vital signs'.
Inclusion Criteria:

 -  All patients admitted to the Papworth Hospital NHS Foundation Trust for routine
 cardiovascular surgery and who are discharged from ICU into the study ward (Mallard).

 Exclusion Criteria:

 -  transplant surgery patients,

 -  VAD patients,

 -  children (less than 18 years old),

 -  prisoners (due to constant observation/security may bias normal level of care),

 -  patients who are subject to additional protections: this includes pregnant women, and
 persons with mental illness and learning disabilities,

 -  patients whose anatomy precludes the use of the required monitoring,

 -  patients who cannot understand written English (and where no translator is available),

 -  patients who are unable to give consent themselves,

 -  patients with learning difficulties who cannot understand the information to consent
 for themselves.
