Impact of a Nurse for Migraine Management: the IMPACT Project
An observational study of Migraine Without Aura and Migraine With Aura, run by Notre-Dame Hospital, Montreal, Quebec, Canada at 1 site in Canada.
Trial summary
Headache disorders are prevalent, disabling, under recognized, under diagnosed and under treated. Migraine has a prevalence of 10% in men and 25% in women in Canada. The treatment of migraine is based on patient education (lifestyle habit modification, trigger avoidance), and pharmacological acute treatment and… Read more about this study

About this study
Official title: Impact of a Nursing Intervention on the Clinical Evolution of Patients at a University Migraine Clinic
Headache disorders are prevalent, disabling, under recognized, under diagnosed and under treated. Migraine has a prevalence of 10% in men and 25% in women in Canada. The treatment of migraine is based on patient education (lifestyle habit modification, trigger avoidance), and pharmacological acute treatment and prophylaxis. A multidisciplinary approach allows a repartition of tasks between different health professionals.
In a 2010 meeting, the Canadian Headache Society members supported the concept of Headache Centers, and a headache nurse was judged as an essential component of such centers.

Gaul has reviewed the structured multidisciplinary approach that could be used in a headache centre and the existing studies using such structures. Five studies did include a headache nurse. No study did observe the impact of a nurse only. Resources in medical care are limited. One study did use a program of 96 hours, which does not seem realistic on the long-term and for a large pool of patients in a public hospital. Patients are not always able to pay for paramedical help such as physiotherapy and psychotherapy. Even if they do, finding a specialized therapist for chronic headache is difficult. Defining the role of a nurse and demonstrating the impact on patient care is therefore a first step in the concept of a headache center. Possible roles of a headache nurse according to Gaul are patient education, follow-up of the treatment plan, addressing patient queries, and monitoring of patient progress. The headache nurse may also participate in research projects. In a hospital Headache Clinic, the nurse may be involved in intra-venous treatments and blood sampling for research.
In summary, evidence to demonstrate the impact of a nurse in a headache clinic is lacking. We propose to study this aspect prospectively. A study with positive findings would encourage health ministers to fund and support headache nurses for headache centers across Canada for headache management. Chronic headache and therefore chronic migraine would be a focus of such centers, since most patients seen in specialized centers are chronic.
HYPOTHESIS: The addition of a headache nurse to the headache team will help the CHUM Migraine Clinic to improve treatment outcome, and reduce the burden of headache. This multidisciplinary approach will also allow a higher efficiency of the team.

STUDY DESIGN:
The goal of this study is to compare two treatment approaches for migraineurs. The first approach will be based on the physician only and is limited to fixed appointments (control group). The second approach will be based on a team involving a headache nurse (active group) who will participate in patient education and follow-up. The goal is to improve patient outcome but also physician productivity.
First 100 patients (control group, phase 1): patients with episodic and chronic migraine will be screened, sign consent and be enrolled. They will be seen by the physician only, without the nurse's support. This situation will reproduce the actual conditions at the clinic. During this phase, the nurse will be involved in the follow-up of known patients (who will not be included in the protocol) and data collection. She will develop her headache management abilities and help the physicians to develop some educational tools for patients.
Following 100 patients (active group, phase 2) : patients with episodic and chronic migraine will be screened and enroled. They will be seen by the physician and nurse team, with a treatment plan tailored to specific needs including regular scheduled visits, follow-up of chronification factors and educational sessions. Phone call follow-ups will be planned. Patients will have an easier and quicker contact with the team in an emergency situation.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Questions about this trial
What is this clinical trial studying?
An observational study of Migraine Without Aura and Migraine With Aura, run by Notre-Dame Hospital, Montreal, Quebec, Canada at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?

The record says: finished, as of the sponsor's last update on 8 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. 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?
Hit-6 score change (time frame: Baseline and 8 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 8 Dec 2016; AzTrials last refreshed its copy on 8 Nov 2026.
