What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether giving general practitioners a rapid C-reactive protein (CRP) test helps them decide when antibiotics are truly needed for patients with respiratory infections. 140 patients with symptoms like cough, fever, or sore throat took part. Doctors in the test group used the Quick read GO device to measure CRP levels, while the control group did not. The goal was to see if the test lowers antibiotic prescribing rates without harming patient care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Quick read GO CRP test (diagnostic device)
What this could lead to
If successful, this approach could help doctors avoid unnecessary antibiotics for respiratory infections, reducing antibiotic resistance.
What could go wrong
This is a small, completed pragmatic trial with 140 participants. Results may not apply broadly, and the test's impact on actual health outcomes (not just prescribing) is not assessed.

Study facts

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients who have received information and given written consent * Patients of any age consulting a general practice with one or more of the following symptoms: fever, cough, arthralgias, myalgias, rhinorrhea; * Symptomatology evolving for more than 24 hours; * Symptoms associated with an upper respiratory tract infection such as otitis, angina, laryngitis, rhinopharyngitis, sinusitis; and/or a lower respiratory tract infection such as acute bronchitis, pneumonia, exacerbation of COPD (chronic obstructive pulmonary disease). Exclusion Criteria: These criteria correspond to factors making interpretation of the CRP value difficult: * Antibiotics taken in the 15 days prior to inclusion * Presence of one of the following signs of severity requiring immediate hospitalization: Impairment of higher functions (altered consciousness) Sign of severity (Pas\<90mmHg; HR\>120/min; FR\>30 cycles/min) Temperature \<35 or \>40°c Inhalation pneumonitis * Sepsis: organ dysfunction, FR\>22cycles/min, PAS≤100 mmHg and Galsgow score ≤ 13(34) * Immediate hospitalization * Pregnancy * Burns * Heat stroke * Presenting with an associated serious pathology: * Associated neoplastic disease in progress * Severe liver failure * Ischemic or thromboembolic pathology * Traumatic pathology * Inflammatory rheumatism * Autoimmune disease
