Development and validation of a telephone classification interview for common chronic headache disorders

Area of Science:

• Neurology
• Primary Care Medicine
• Clinical Interviewing

Background:

• Chronic headache management requires accurate classification in primary care settings.
• Existing diagnostic tools may not be suitable for use by non-headache specialists.
• A validated telephone interview is needed to identify common chronic headache disorders.

Purpose of the Study:

• To develop and validate a telephone classification interview for common chronic headaches.
• To enable non-specialists to accurately diagnose conditions like migraine and tension-type headache (TTH).
• To identify medication overuse headache and exclude other secondary headaches.

Main Methods:

• A consensus conference informed the interview's logic model.
• Nurses conducted telephone interviews with primary care patients.
• Headache specialists performed validation interviews to assess agreement.

Main Results:

• Initial agreement between nurses and doctors showed moderate concordance (kappa=0.31, PABAK=0.51).
• Following a review, a sensitivity test revealed very good agreement (kappa=0.53, PABAK=0.81).
• The interview demonstrated reliability in classifying chronic headache types.

Conclusions:

• An evidence-based telephone interview for chronic headache classification was successfully developed and validated.
• This tool empowers non-headache specialists in primary care to accurately diagnose common headache disorders.
• The interview facilitates better management of chronic headache conditions.
