Headache infusion centers: A survey on treatments provided, infusion center operations, and barriers to developing new infusion centers

Safety, tolerability, and effectiveness of repetitive intravenous dihydroergotamine for refractory chronic migraine with cardiovascular risk factors: A retrospective study

BACKGROUND

Dihydroergotamine (DHE), like triptans, is contraindicated in patients with ischemic heart disease or coronary vasospasm. Its true safety, tolerability, and efficacy in patients with cardiovascular risk without ischemic heart disease or coronary vasospasm remain unclear.

OBJECTIVES

To assess the safety, tolerability, and effectiveness of repetitive intravenous DHE in patients with cardiovascular risk factors.

METHODS

A single-center, retrospective cohort study was conducted at the Jefferson Headache Center inpatient unit for refractory chronic migraine patients treated with our intravenous DHE protocol between January 1, 2019, and October 15, 2019. We evaluated tolerability and effectiveness outcomes based on atherosclerotic cardiovascular disease 10-year calculated risk scores, stratified into low (<5.0%) and elevated (≥5.0%) risk. Data were presented in mean ± standard deviation or median (25th percentile, 75th percentile) if non-normally distributed.

RESULTS

Among 347 patients (median age of 46 [36, 57], female n = 278 [80.1%]), who received inpatient intravenous DHE, 227 patients (age 53 [45, 60], female 81.1%) had calculable risk scores, 64 (28.2%) had elevated risk, and 38 (16.7%) had cardiology consultations. There were no clinically significant electrocardiogram abnormalities or cardiovascular adverse events. The median hospital length of stay was 6 (5, 7) days. Compared to the low-risk group, those with elevated risk had higher nausea (31.3% vs. 14.1%, p = 0.008), but similar initial DHE dose (0.5 [0.25, 0.5] vs. 0.5 [0.25, 0.5], p = 0.009), lower final DHE dose (0.75 [0.5, 1] vs. 1 [0.75, 1] p < 0.001), and lower pain reduction after admission (-3.8 [2.1, 6] vs. -5 [3, 7] p = 0.037).

CONCLUSION

Patients receiving intravenous DHE by the Jefferson Headache Center inpatient headache protocol had significantly reduced pain severity at discharge. No clinically significant cardiac or electrocardiogram abnormalities were detected in patients with elevated (or low) atherosclerotic cardiovascular disease risk. Repetitive intravenous DHE used by our protocol was safe in refractory chronic migraine patients.

The role of urgent care centers in headache management: a quality improvement project

Background

Patients with headache often seek urgent medical care to treat pain and associated symptoms that do not respond to therapeutic options at home. Urgent Cares (UCs) may be suitable for the evaluation and treatment of such patients but there is little data on how headache is evaluated in UC settings and what types of treatments are available. We conducted a study to evaluate the types of care available for patients with headache presenting to UCs.

Design

Cross-Sectional.

Methods

Headache specialists across the United States contacted UCs to collect data on a questionnaire. Questions asked about UC staffing (e.g. number and backgrounds of staff, hours of operation), average length of UC visits for headache, treatments and tests available for patients presenting with headache, and disposition including to the ED.

Results

Data from 10 UC programs comprised of 61 individual UC sites revealed: The vast majority (8/10; 80%) had diagnostic testing onsite for headache evaluation. A small majority (6/10; 60%) had the American Headache Society recommended intravenous medications for acute migraine available. Half (5/10) had a headache protocol in place. The majority (6/10; 60%) had no follow up policy after UC discharge.

Conclusions

UCs have the potential to provide expedited care for patients presenting for evaluation and treatment of headache. However, considerable variability exists amongst UCs in their abilities to manage headaches. This study reveals many opportunities for future research including the development of protocols and professional partnerships to help guide the evaluation, triage, and treatment of patients with headache in UC settings.
