Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention (a sedation guideline previously found to be beneficial) was tested in a quasi-experimental preintervention study (n=322). The study was conducted in two phases, a ten-month preintervention data collection phase (November 2002 to October 2003) was followed by a twelve-month postintervention phase (November 2003 to December 2004).

Outcomes
Primary outcome [1] 332 0
The primary aim of the study was to determine whether an algorithm based sedation guideline reduced duration of mechanical ventilation for ICU patients.
Timepoint [1] 332 0
Secondary outcome [1] 738 0
To determine whether the use of a sedation guideline improved the experience of recovery after ICU for mechanically ventilated patients, reflected by lower ETIC-7 scores.
Timepoint [1] 738 0
Secondary outcome [2] 739 0
To determine whether the use of a sedation guideline reduced the length of ICU stay
Timepoint [2] 739 0
Secondary outcome [3] 740 0
The incidence of unscheduled self-extubations
Timepoint [3] 740 0
Secondary outcome [4] 741 0
The rate of reintubation and the number of tracheostomies.
Timepoint [4] 741 0
Secondary outcome [5] 742 0
The effect of the study intervention on the costs of intravenous analgesic and sedative medications was also examined.
Timepoint [5] 742 0
Secondary outcome [6] 743 0
In addition the rate of adoption of the new practices of sedation scoring and use of a sedation guideline by bedside clinicians was explored.

Eligibility
Key inclusion criteria
Research participants were selected on the basis of whether they were mechanically ventilated while they were in intensive care. Participants were eligible for inclusion if they were adults older than 17 years.
Minimum age
17 Years
Maximum age
Not stated
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Patients were excluded if they: i) had a primary diagnosis of head injury or other neurological insult and where the aim of sedation was to reduce or minimise intracranial pressure and/or cerebral artery spasm.ii) were not expected to live for more than 24 hours after admission, e.g. patients who had a diagnosis of brain stem death or who were likely to require brain stem death tests.iii) had an explicit ventilation weaning goal on admission e.g. post operative coronary artery bypass graft patients recovering from general anaesthetic.iv) were likely to be ventilated for more than 21 days, e.g. patients with neurological conditions such as Guillain-Barre Syndrome and myasthenia gravis, and patients who had sustained a recent complete spinal cord lesion above cervical spine vertebra number five.v) had previously been enrolled in the study and were readmitted to the intensive care unit more than 72 hours after they were discharged. However for the purpose of this project patients who were readmitted within 72 hours were regarded as being in the same ICU admission.vi) had sustained a burn injury covering more than 15% of their body surface area.
