Study summary

This study is designed to collect data from 8,476 fracture patients during a pre-and post-intervention phases of two years length each. The intervention consists on the implementation of the AOT SSI Prevention Bundle.

D

Read the detailed description

During the first phase of the study, 4,238 patients will be recruited and the baseline incidence of surgical site infection at each participating site will be determined. At the beginning of the third year, the bundle will be implemented and data on 4,238 additional patients will be collected. The incidence rate on surgical site infection before and after the intervention will be compared. We hypothesize that this intervention will reduce the infection rate within the first 3 months after surgery from 6% to 4.5% (5% to 3.75% in closed fractures and from 10% to 7.5% in open fractures).

        • Willingness and ability to participate in the clinical investigation according to the Clinical Investigation Plan (CIP)
        • Signed and dated EC/IRB approved written informed consent

Exclusion criteria

Exclusion Criteria:

  • Pathologic fracture secondary to tumors, infection or cysts
  • Patients with an underlying chronic, bone and joint infection or prior history of a bone and joint infection
  • Refracture and non-union
  • Peri-implant fractures
  • Patients with terminal illness

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • No intervention
    pre-intervention

    The number of SSI are collected in this phase. Patients with fractures are enrolled and their standard of care treatment is observed.

  • Other
    post-intervention

    Here the same observations are made as in the first arm, however this is after the hospital staff was thought the prevention measures (all by themselves approved) and enforced to be applied.

    Behavioral: Implementation of the AO Trauma SSI Prevention Bundle

Interventions

  • BehavioralImplementation of the AO Trauma SSI Prevention Bundle

    AOT SSI Prevention Bundle Preventive measure 1. Antibiotic prophylaxis 2. Perioperative antibiotics 3. Oxygen administration 4. Patient temperature 5. Surgeon protective wear 6.

What researchers measure

Primary outcomes

  1. Infection Rate

    Surgical site infection rate as defined by CDC or FRI definition

    Time frame: within 3 months after surgery

Secondary outcomes

  1. Implementation success of the AOT SSI Prevention Bundle

    Compliance rate for each measure of the bundle before and after the intervention

    Time frame: up to 48 months

  2. Evaluation of attitudes, perception and knowledge concerning SSI

    Cross sectional survey of surgeons at participating sites performed before and after the implementation of the AOT SSI Prevention Bundle

    Time frame: up to 48 months

  3. Surgeon satisfaction

    Cross sectional survey of opinion concerning user friendliness of the AOT SSI Prevention Bundle, value of the educational intervention and intention to adopt the AOT SSI Prevention Bundle long term before and after its implementation

    Time frame: up to 48 months

  4. Health-economic analysis

    The clinical effectiveness of the implementation of the AOT SSI Prevention Bundle and consecutively the costs saved by preventing infections and its treatment is compared against the costs which have to be invested in order to implement the AOT SSI Prevention Bundle (e.g. costs generated by development of teaching material, time needed to teach/implement the intervention, extra material needed according to the interventions etc.).

    Time frame: up to 48 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 18, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
