About this study
The ProACT study is a 5 year, multicenter study that will test the effect of implementation of a novel procalcitonin guideline on antibiotic use and adverse outcomes in Emergency Department (ED) patients with Lower Respiratory Tract Infection (LRTI).
Read the detailed description
There is a need for improved decision-making for antibiotic prescription in acute suspected infection. Infections, particularly in the early stages, can have protean manifestations, often do not manifest with "classic" signs, and clinically overlap with non-infectious conditions. However, the imperative to quickly give antibiotics for bacterial infection has led to antibiotic overuse and resistance.
Strategies that combine novel diagnostics with therapeutics have improved decision-making in oncology, cardiology, and other fields. These strategies aim to identify those patients most likely to be helped or harmed by the therapeutic intervention and allow more individualized care. This approach takes diagnostics to the next level, by demanding a test not only measure well, but also that clinical care be improved by tying the test to a treatment strategy.
Procalcitonin, a novel biomarker of bacterial infection, may help physicians make more appropriate antibiotic decisions. Lower respiratory tract infection (LRTI) is an ideal trial population. LRTI accounts for a large proportion of antibiotic prescription, and exemplifies the imprecise clinical phenotype of infection.However, key questions of generalizability and safety preclude widespread application.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Procalcitonin levelOther
Also called PCT level
A procalcitonin (PCT) will be drawn level within one hour after randomization in the ED, and if hospitalized, 6-24 hours after the initial ED blood draw, and on Days 3, 5, and 7. Days 3, 5, and 7 blood draws for procalcitonin will only occur in hospitalized patients on antibiotics and/or at the treating physician's discretion.
Results of procalcitonin (PCT) level to treating clinicianOther
In the ED, we will quickly (<1 hour goal) provide clinicians the procalcitonin result.
Provide procalcitonin guideline to treating clinicianOther
Procalcitonin antibiotic guideline --
Procalcitonin level (ug/L) -- Bacterial etiology -- Recommendation
< 0.1 -- Very unlikely -- Antibiotics strongly discouraged(1)
0.1 - 0.25 -- Unlikely -- Antibiotics discouraged(1)
> 0.25 - 0.5 -- Likely -- Antibiotics recommended(2)
> 0.5 -- Very likely -- Antibiotics strongly recommended(2)
- Initial antibiotics can be considered for critical illness, Legionella pneumophilia. Procalcitonin should be evaluated in context with all findings and the total clinical status; clinical judgment always necessary.
- For outpatients, antibiotic duration based on level (> 0.25-0.5 ug/L:3 days; > 0.5-1.0 ug/L:5 days; >1.0 ug/L:7 days). Physician follow-up is recommended.
Telephone VisitOther
We will collect the number of antibiotic days during telephone visits occurring on or around Day 15 and Day 30

What is being measured
The primary outcome is the main question the study is designed to answer.
Total Antibiotic Exposure Days
Total antibiotic exposure, defined as the total number of antibiotic-days by Day 30.
Measured: 30 days
Number of Participants With Any Adverse Outcome
Primary Safety Outcome - Combined endpoint of adverse outcomes (death, endotracheal intubation, vasopressors, renal failure, lung abscess/empyema, pneumonia in non-CAP patient, and hospital readmissions) that could be attributable to withholding antibiotics in lower respiratory tract infection (LRTI).
Number is based on the number of participants that experienced any adverse outcome.
Measured: 30 days
Secondary outcomes (1)
Antibiotic Prescription in Emergency Department(ED)
Antibiotic prescription in the ED includes post-randomization receipt of antibiotics in ED and provision of an antibiotic prescription for patients at the time of discharge from the ED.
Measured: While in the ED or before ED discharge (majority patients < 1 day)

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?
Yes. Results are posted in the registry (first posted 15 Jan 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Total Antibiotic Exposure Days (time frame: 30 days). The study lists 2 primary outcomes in all. 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 NCT02130986, which also lists 23 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 15 Jan 2019; AzTrials last refreshed its copy on 27 Oct 2026.
