Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - SDD Oral Paste
Treatment: Drugs - SDD Gastric Suspension
Treatment: Drugs - Intravenous Antibiotic

No Intervention: Control group- standard care - Standard care- In Australia there are no national guidelines so local policy is determined by each ICU. We are recommending (but not mandating) that control and SDD group management be in line with these national guidelines. We will recommend control and SDD group management is in line with current national standards of practice that may or may not include a VAP bundle. We will monitor record data regarding the nature and delivery of the control and SDD group co-interventions.

Experimental: SDD intervention group - The intervention will entail:
A six-hourly topical application of 0.5g paste, containing colistin 10mg, tobramycin 10mg and nystatin 125,000 IU, to the buccal mucosa and oropharynx
A six-hourly administration of 10 mL of a suspension containing 100 mg colistin, 80 mg tobramycin and 2 x 10^6 IU nystatin, to the gastrointestinal tract via a gastric/post-pyloric tube
A four-day course of an IV antibiotic. Patients not already receiving a therapeutic antibiotic will be prescribed cefotaxime 1g six-hourly or ceftriaxone 1g daily, with dose adjusted as appropriate for organ dysfunction. Ciprofloxacin (400mg 12-hourly) may be used as an alternative if there is a contraindication to cephalosporins (e.g. allergy). Patients already receiving an alternative IV antibiotic to treat infection will not receive this additional IV antibiotic, but will continue the prescribed antibiotic for the usual duration of therapy.


Treatment: Drugs: SDD Oral Paste

2. A six-hourly administration of 10 mL of a suspension containing 100 mg colistin, 80 mg tobramycin and 2 x 10 ^6 IU nystatin, to the gastrointestinal tract via a gastric/post-pyloric tube

A four-day course of an intravenous antibiotic in patients not already receiving a therapeutic antibiotic

Eligibility
Key inclusion criteria
Site inclusion for cluster study- A general ICU or complex of ICUs (medical, surgical,
mixed) capable of treating mechanically ventilated critically ill adult patients.

Patient inclusion criteria

1. All patients who are mechanically ventilated via an endotracheal tube on admission to
ICU and who are predicted to remain ventilated beyond the end of the calendar day
after the day of ICU admission, or

2. All patients who become mechanically ventilated via an endotracheal tube during their
ICU stay and who are predicted to remain ventilated beyond the end of the calendar day
after the day they are first ventilated, or

3. All patients not already recruited who are receiving mechanical ventilation via an
endotracheal tube and are expected to receive ongoing ventilation for a further 48
hours or more despite an earlier prediction that ventilation would be discontinued
earlier.

Site exclusion criteria for cluster study-

1. Unwilling or unable to follow trial protocols.

2. Unable to capture the minimum data set required for the study.

3. Isolated specialty ICUs not co-located with a general ICU, such as solely cardiac,
neurological/neurosurgical and burns ICUs, but such specialty patients cared for in
general ICUs will be included

4. Specialty paediatric ICUs
Minimum age

Summary
Brief summary
Introduction- Hospital acquired infections (HAI) are a major cause of morbidity and mortality
and increase health care costs. Critically ill patients are particularly susceptible to these
infections and have an even higher mortality. One intervention that has gained much interest
in the medical literature for reducing infection rates and deaths from HAIs is selective
decontamination of the digestive tract (SDD). SDD involves the application of antibiotic
paste to the mouth, throat, stomach and a short course of intravenous antibiotics. The
evidence supporting the use of SDD for saving lives and preventing infections is actually
quite strong. However, health care professionals in many parts of the world have refrained
from using SDD due to fears of the effects of overuse of antibiotics on the frequency of
infections with resistant bacteria such as multi-resistant Gram negative organisms, MRSA and
Clostridium difficile.

SuDDICU is a cross-over, cluster randomised trial comparing the effect of using selective
decontamination of the digestive tract (SDD) plus standard care, to standard care alone on
hospital mortality in patients receiving mechanical ventilation in the intensive care unit
(ICU).

Secondary outcomes include an ecological assessment and a long-term health economic analysis.
