About this study

The study objective was to identify predictive criteria of severe non-traumatic secondary headache among the information gathered during telephone interview conducted by the on-call regulating physician at the Centre15.

Read the detailed description

Headache accounted for 1% of outpatient consultations, 2% of hospital emergency department visits and, at the French national level, 1% of complaints motivating calls to the prehospital emergency medical service units (The French, physician-led Emergency Calls Centers , called either "Center 15" or Service d'Aide Médicale d'Urgence [SAMU]). In 2009, the French "SAMU-Urgences de France" society proposed a classification and diagnostic tool for evaluating the headache patient, which is yet to be validated by a clinical study. Most patients with headache spontaneously consulted the emergency department (ED) and only 4 to 5% of patients entered ED through ambulance, fire and rescue department, medicalized ambulance (SMUR), or police. Patients attending emergency service for unusual sudden headache arriving by ambulance had a higher frequency of subarachnoid haemorrhage.

Headache studies have mainly been conducted in the ED. The Ottawa rule published by Perry et al. in 2013 proposed criteria for conducting explorations for subarachnoid hemorrhage (SAH) in patients over 15 years of age with severe, non-traumatic headache, having reached maximum intensity within one hour.

Unlike the primary headaches, secondary headaches are associated with underlying causes. Among the severe secondary headaches (SSH) (4 to 5% of headaches), non-traumatic subarachnoid haemorrhage was not diagnosed in 5.4% to 12% of cases in ED resulting in increase in mortality from 5 to 14%.

In 2018, French guidelines for the emergency management of headache recognized criteria likely to be at risk of Severe Secondary Headache, requiring explorations in emergencies for sudden headaches or thunderclaps headaches (i.e. reaching maximum intensity in less than a minute), recent headaches or progressive worsening (<7 days) and unusual, association with fever (apart from an obvious cause), association with signs of neurological impairment, suspicion of carbon monoxide poisoning, immunosuppression (neoplasia, HIV). Any unusual headache in a patient with recurrent paroxysmal or chronic headache should be considered secondary until proven otherwise. Subarachnoid hemorrhages were present in 11% of patients with sudden, intense and unusual headache.

In the French department of Loiret, patients with subarachnoid haemorrhage required a transfer out of the department to the nearest regional referral teaching hospital, by lack of adequate equipment and expertise for interventional neurology. Early diagnosis was therefore critical. In fact, an untreated cerebral aneurysm rupture increased bleeding recurrence by 3-4% in the first 24 hours.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • QuestionnaireOther

    The regulatory scheme applied to all investigative centers is as follows:

    • Call from Center 15 by a major patient for secondary headache no traumatic. (i.e. not having been the victim of a head trauma during the 48 hours preceding the call)
    • Detection of the pattern of "non-traumatic headache", by the regulatory assistant medical with registration of the word "cephareg" in the medical regulation software in order to alert the regulator about the possible inclusion of the patient
    • If possible, patient information on the collection of their data for research and possibility of opposing
    • Filling of a medical questionnaire by the regulating doctor
    • Weekly collection of medical questionnaires by investigating doctors

What is being measured

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

  1. Proportion of patients with diagnosis of non-traumatic secondary headache

    Proportion of patients with diagnosis of non-traumatic secondary headache attended by the French emergency services operating

    Measured: Day 21

Secondary outcomes (2)

  1. Proportion of patients requiring an admission to Intensive Care Unit

    Proportion of patients requiring an admission to the Intensive Care Unit between triage in the emergency department (Day 0) and Day 2

    Measured: Day 2

  2. Number of patients with early mortality

    Number of patients who died in hospital at day 7

    Measured: Day 7

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 4 inclusion and 4 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 Mar 2022. 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 France. 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?

Proportion of patients with diagnosis of non-traumatic secondary headache (time frame: Day 21). 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 NCT04617808, which also lists 7 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 28 Mar 2022.
