Scientific titleComparison of an automated weaning programme and a standard clinical weaning protocol for weaning critically ill patients: a randomised controlled trial
Study objectivesWill the use of an automated weaning system shorten the duration of mechanical ventilation, and will this be associated with reduced ventilator-associated complications e.g. pneumonia, tracheostomy?
Ethics approval(s)St Thomas' Hospital Research Ethics Committee
Health condition(s) or problem(s) studiedProcess of weaning from mechanical ventilation
InterventionThis is a randomised controlled trial comparing the ICU's standard ventilator weaning protocol and the SmartCare automated weaning system. Patients who are assessed as likely to need mechanical ventilation for a period of 48 hours or more will be randomised to be weaned from mechanical ventilation using either the standard protocol or the automated weaning system. Weaning will be initiated when, in the opinion of the clinical team, the patient is sufficiently improved as to be able to tolerate a spontaneous mode of ventilation and has met defined gas exchange and ventilatory support criteria. Once in the weaning phase, weaning will proceed according to the manual or SmartCare algorithms but will be suspended if the patient's clinical condition deteriorates, and re-instituted once the patient has improved sufficiently for weaning to recommence.
Intervention typeOther
Primary outcome measureTime from the initiation of weaning to successful separation of the patient from the ventilator, defined as no longer needing mechanical ventilation for a minimum period of 48 hours.
Secondary outcome measuresAdded as of 10/12/2007:
1. Mortality (28-day, ICU and hospital, six-months)
2. Infectious complications (e.g. pneumonia, wound infection, abscesses)
3. APACHE II
4. Organ failure-free days
5. LOS in ICU
6. LOS in hospital (intervention until discharge)
7. Duration of antibiotic treatment (antibiotics days)
8. Duration of ventilation (ventilator days)
9. Duration of renal support

Editorial Notes

14/06/2016: No publications found, verifying study status with principal investigator.
13/02/2009:
1. The Scientific title has been added.
2. The anticipated end date has been updated from 31/12/2008 to 30/06/2010
3. The sponsor has been corrected from "Fresenius Kabi Deutschland GmbH (Germany)" to "Guy's and St. Thomas' NHS Foundation Trust (UK)". This is due to an error in initial information provided for this ISRCTN record.
10/12/2007:The anticipated end date has been updated from 01/12/2005 to 31/12/2008 and the target number of participants has been updated from 100 to 500.
