Med Use Examined in Migraine & Headache Care – via

According to results of a retrospective study presented at PAINWeek 2017, opioids are not only prescribed to a large proportion of patients diagnosed with headache (H) and/or migraine (M), but are also more commonly used than triptan medications.

During the analysis, 547,558 adults with at least two ICD-9-CM or ICD-10-CM diagnostic code claims for H or M were identified in the HealthCore Integrated Research Database.  Analysis included the demographics, comorbidities, and prescription medication use of these patients, as well as the proportion of days covered (PDC)³ 80% and persistence (no gap of ³30 days in preventive medication supply).
The five mutually exclusive cohorts were H only (n=365,091), M only (n=94,492), H/M on the same day (H/M, n=7,461), H then M (H-M, n=46,656), and M then H (M-H, n=33,858).
The study authors reported, “Approximately 11% of patients with a first diagnosis of H had a subsequent M diagnosis, and 25% of patients with a first diagnosis of M had a subsequent H diagnosis.”  The median time found between diagnoses was 231 days for the H-M group compared to 252 days for the M-H group.  Additionally, patients in the H only group were found to have a higher rate of vascular comorbidities, such as hypertension/dyslipidemia, ischemic heart disease, and cerebrovascular disease, compared to the other cohorts.
Medication use was also found to vary among patients in different cohorts.  Results of the study found that only 4% of H only patients used triptan medications compared to 46-50% of patients in the other 4 groups.  The study authors reported, “Opioid use was fairly high in all groups [H (61%), M (57%), H/M (74%), H-M (71%), and M-H (74%)].”  They added, “Triptan and opioid use between diagnoses among H-M was 18% and 56%, respectively, and among M-H 38% and 56%, respectively.”
