Dr. Callaghan’s health services research focuses on improving the efficiency of neurologic diagnostic testing, with a specific interest in neuroimaging for headache, one of the most common reasons for a patient to seek medical care. He has also evaluated costs related to neurologic care in the U.S., including a project that determined that the country spends more money on neurologist-ordered MRIs than on neurologists’ office visits. He has also investigated the appropriateness of diagnostic testing in patients with distal symmetric polyneuropathy, and his work has led to a Choosing Wisely recommendation to not perform MRIs for patients with this condition.
