Headache neuroimaging: Routine testing when guidelines recommend against them

Open access

Abstract

Aims: The aim of this article is to determine the patient-level factors associated with headache neuroimaging in outpatient practice. Methods: Using data from the 2007–2010 National Ambulatory Medical Care Surveys (NAMCS), we estimated headache neuroimaging utilization (cross-sectional). Multivariable logistic regression was used to explore associations between patient-level factors and neuroimaging utilization. A Markov model with Monte Carlo simulation was used to estimate neuroimaging utilization over time at the individual patient level. Results: Migraine diagnoses (OR = 0.6, 95% CI 0.4–0.9) and chronic headaches (routine, chronic OR = 0.3, 95% CI 0.2–0.6; flare-up, chronic OR = 0.5, 95% CI 0.3–0.96) were associated with lower utilization, but even in these populations neuroimaging was ordered frequently. Red flags for intracranial pathology did not increase use of neuroimaging studies (OR = 1.4, 95% CI 0.95–2.2). Neurologist visits (OR = 1.7, 95% CI 0.99–2.9) and first visits to a practice (OR = 3.2, 95% CI 1.4–7.4) were associated with increased imaging. A patient with new migraine headaches has a 39% (95% CI 24–54%) chance of receiving a neuroimaging study after five years and a patient with a flare-up of chronic headaches has a 51% (32–68%) chance. Conclusions: Neuroimaging is routinely ordered in outpatient headache patients including populations where guidelines specifically recommend against their use (migraines, chronic headaches, no red flags).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
