Investigation of the Effect of Age and Injury Severity on Short-term Intra-hospital Outcomes After Surgical Stabilized Rib Fractures

April 28, 2026 updated by: University Hospital Muenster
The study aims to investigate the effect of surgical stabilisation of rib fractures (SSRF) on clinical outcomes measured during the hospital stay (mortality, days on a mechanical ventilator, intensive care unit and hospital length of stay, rate of complications). Furthermore, the effect of the patients age and overall injury severity on the outcomes after SSRF will be investigated. We hypothesise that the combination of high age and high injury severity will lead to worse outcomes after SSRF.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
In hospital-mortality
Time Frame: From injury up to initial hospital discharge or death, whichever came first, assessed up to 2 month.
Mortality rate from injury to initial hospital discharge, binary
From injury up to initial hospital discharge or death, whichever came first, assessed up to 2 month.
Intensive care unit length of stay
Time Frame: From injury up to initial hospital discharge or death, whichever came first, assessed up to 2 month.
The duration in days a patient spent in the intensive care unit from the time of hospital admission to the time of initial hospital discharge.
From injury up to initial hospital discharge or death, whichever came first, assessed up to 2 month.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Intubation rate
Time Frame: From injury up to initial hospital discharge or death, whichever came first, assessed up to 2 month.
Proportion of patients intubated at any time
From injury up to initial hospital discharge or death, whichever came first, assessed up to 2 month.
