About this study

Official title: Comparison of Standard Isolation With Targeted Isolation for Preventing Nosocomial Transmission of MRSA and VRE: A Pilot Clinical Trial

Hospital-acquired infections are common and frequently lead to poor outcomes, including death, in affected patients. Two common organisms that cause infections in the hospital are methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE). One strategy used to prevent these infections is contact isolation of hospitalized patients with MRSA and/or VRE. It is unclear whether contact isolation decreases the rate of infection with MRSA and/or VRE. The CONTACT-PILOT study is designed to test the hypothesis that contact isolation decreases the rate of infection with MRSA and/or VRE in patients in the intensive care unit (ICU). The study will enroll all adults in the Medical ICU and will run between September 2017 and April 2018. During some months, all patients in the Medical ICU patients will be placed in isolation for MRSA or VRE if they have a current infection or colonization with either organism, or a recent history thereof. During other months, patients will only be placed in isolation for MRSA or VRE if they have an active, highly-transmissible infection with either organism, such as a pneumonia or an open, draining wound.

Read the detailed description

CONTACT-PILOT is a single center, pilot, multiple crossover, cluster-randomized trial of contact isolation for MRSA and VRE in the Vanderbilt Medical Intensive Care Unit (MICU) in order to determine if contact isolation reduces the rate of ICU-acquired infection with MRSA and/or VRE. Specifically, the study will randomly assign the entire MICU to one of two contact isolation strategies for 2 months, and then switch the entire MICU over to the second strategy. The first strategy is the current practice, also referred to as standard contact isolation, which is to place all patients with MRSA and/or VRE infection or colonization (or a history of either) on contact isolation. The second strategy is targeted contact isolation, in which patients with MRSA and/or VRE would only be placed on contact isolation if they have an active infection with one (or both) of these organisms with a high risk of transmission, such as an open, draining wound or a pneumonia. The study will be divided into four alternating 2-month treatment blocks, two for each strategy, with one "run-in" week at the start of each treatment block in order to transition between the two treatment strategies, for a total study duration of 8 months. The interventions will occur between September 1, 2017 and April 30, 2018. All adult MICU patients will be enrolled in the study. The primary outcome will be the rate of new ICU-acquired MRSA and VRE infections. Data analysis will be performed using a pre-specified data analysis plan. This study is being performed as a preliminary study to evaluate the feasibility and safety of the study plan.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Standard Contact IsolationOther

    Also called Standard Contact Precautions

    With regards to MRSA and VRE, the wearing of gowns and gloves will be required for all staff entering a patient room if the patent has an infection or colonization with MRSA or VRE or a recent history (within 90 days) of either

  • Targeted Contact IsolationOther

    Also called Targeted Contact Precautions

    With regards to MRSA and VRE, the wearing of gowns and gloves will be required for all staff entering a patient room if the patient has an active, highly-transmissible infection with MRSA and/or VRE.

    A highly-transmissible infection is defined as one with uncontained secretions or excretions (diarrhea, vomiting, or open draining wounds) or pneumonia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Composite rate of ICU-acquired MRSA or VRE infections (time frame: 48 hours after enrollment to 48 hours after study ICU discharge, censored at 28 days after enrollment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03268122, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jun 2018.
