Plain English Summary

Background and study aims
In intensive care units (ICUs), the bacteria Pseudomonas aeruginosa is a major cause of healthcare-associated infections. The issue of physical contact precautions as contributory factors for reducing Pseudomonas aeruginosa infections in ICUs remains questioned.
We aimed to evaluate the benefit of the addition of contact precautions to standard precautions in P. aeruginosa-positive patients for reducing the risk of ICU-acquired P. aeruginosa infections.

Who can participate?
Adult (older than 15-year old) patients admitted for more than 24 hours in ICU

What does the study involve?
Ten French ICUs were randomly assigned to take additional precautions or standard precautions for 6 months, followed by a 3 month break, followed by 6 months using the other precautions to the first 6 months.

What are the possible benefits and risks of participating?
Minimal risk of adverse events

Where is the study run from?
University Hospital of Besançon (France)

When is the study starting and how long is it expected to run for?
May 2011 to December 2014

Who is funding the study?
This work was supported by the French Ministry of Health (PHRC national 2011)

Study acronymDPCPYO
Study hypothesisTo evaluate the benefits of contact precautions over standard precautions for reducing the incidence of ICU-acquired Pseudomonas aeruginosa infections
Ethics approval(s)Approved 16/05/2011, The human research ethics committee of the Besançon University Hospital (Le comité de protection des personnes (CPP) - EST II, 2 Place Saint-Jacques, Besançon, France; +33 3 81 21 93 12; cpp@chu-besancon.fr), ref: 2011-A01013-38
ConditionPrevention of ICU-acquired Pseudomonas aeruginosa infections
InterventionTen French ICUs were randomly assigned (1:1) to sequence 0-1 (6-month control period /3-month wash-out period/6-month intervention period) or sequence 1-0 (6-month intervention period/3-month wash-out period/6-month control period).

Intervention period (the addition of contact precautions to standard precautions) vs control period (standard precautions) for Pseudomonas aeruginosa-positive patients with a surveillance screening programme.

The interventions (contact precautions) are the systematic implementation of the following measures: placing in single room or cohorting, signalling on the door, wearing gown, appropriate hand hygiene at the exit of the patient room and prescribing of contact precautions in the medical record.
Intervention typeBehavioural
Primary outcome measureRate of ICU-acquired Pseudomonas aeruginosa infections measured using routine diagnostic samples (blood, bronchoalveolar lavage, urine…) with routine clinical surveillance of patients that remained unchanged throughout the study period. Patients were screened for P. aeruginosa carriage (throat swab/tracheal aspirate and rectal swab) upon ICU admission (≤ 48 h) and once a week thereafter.
Secondary outcome measures1. Rate of Pseudomonas aeruginosa acquisition (acquired infection and/or colonisation) measured as above.
2. Clonal relatedness of P. aeruginosa isolates measured using the Simpson diversity index and transmission index of Pseudomonas aeruginosa isolates within ICUs throughout the study.
