About this study

Official title: Is the EBJIS Definition of Prosthetic Joint Infection Meaningful in Our Clinical Practice? - a Multicentric Validation Study

This retrospective multi-center, multi-national cohort study is to validate the European Bone and Joint Infection Society (EBJIS) Definition of Prosthetic Joint Infection. Specifically, it is to analyze the outcome of the Infection Likely group and compare it to the Infection Unlikely group as well as other subgroups within previous validated definitions (Musculoskeletal Infection Society (MSIS)/International Consensus on Musculoskeletal Infection (ICM) 2013 and ICM 2018).

Read the detailed description

Periprosthetic joint infection (PJI) is a major burden for healthcare systems. The European Bone and Joint Infection Society (EBJIS) proposed a new set of criteria introducing a three level 'traffic light' distinction: Infection Unlikely, Infection Confirmed but also an intermediate group called Infection Likely (but nor confirmed). This retrospective multi-center, multi-national cohort study is to validate the EBJIS Definition of Prosthetic Joint Infection. Specifically, it is to analyze the outcome of the Infection Likely group and compare it to the Infection Unlikely group as well as other subgroups within previous validated definitions (Musculoskeletal Infection Society (MSIS)/International Consensus on Musculoskeletal Infection (ICM) 2013 and ICM 2018).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Prosthetic Joint Infections (with or without the need for further surgery)

    Number of Prosthetic Joint Infections (with or without the need for further surgery) among each PJI definition ("Infection Unlikely", "Infection Confirmed", "Infection Likely (but nor confirmed)"

    Measured: since 01.01.2013 with a minimum of two years follow up

  2. Prosthetic Joint Infections (with or without the need for further surgery)

    Number of Prosthetic Joint Infections (with or without the need for further surgery) according to different classifications (EBJIS, MSIS/ICM 2013, ICM 2018).

    Measured: since 01.01.2013 with a minimum of two years follow up

  3. Need for Revision Surgery

    Number of Revision Surgeries (for all causes, PJI and aseptic failure) among each PJI definition ("Infection Unlikely", "Infection Confirmed", "Infection Likely (but nor confirmed)"

    Measured: since 01.01.2013 with a minimum of two years follow up

  4. Need for Revision Surgery

    Number of Revision Surgeries (for all causes, PJI and aseptic failure) according to different classifications (EBJIS, MSIS/ICM 2013, ICM 2018).

    Measured: since 01.01.2013 with a minimum of two years follow up

  5. Survival rates of different subgroups among each PJI definition

    Survival rates of different subgroups among each PJI definition ("Infection Unlikely", "Infection Confirmed", "Infection Likely (but nor confirmed)"

    Measured: since 01.01.2013 with a minimum of two years follow up

  6. Survival rates between different definitions

    Survival rates between different classifications (EBJIS, MSIS/ICM 2013, ICM 2018).

    Measured: since 01.01.2013 with a minimum of two years follow up

Questions about this trial

What is this clinical trial studying?

An observational study of Periprosthetic Joint Infection (PJI), run by University Hospital, Basel, Switzerland at 2 sites in 2 countries.

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 3 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 28 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Portugal, Switzerland. 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?

Prosthetic Joint Infections (with or without the need for further surgery) (time frame: since 01.01.2013 with a minimum of two years follow up). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 28 Feb 2024.
