Abstract
OBJECTIVE To evaluate differences in emergency department (ED) utilization and quality of care for migraine in patients with rural and nonrural residences. BACKGROUND Migraine is a significant problem in the United States with direct health-care utilization cost amounting to US $4.2 billion annually. A considerable portion of this cost is attributed to more than 4 million annual ED visits for migraine and headache. Previous research has documented health disparities among rural populations in other disease states, which can be influenced by factors such as socioeconomic status and health-care access. Given these associations, it was hypothesized that patients with rural residence in a national sample would have increased ED utilization for migraine compared to patients with nonrural residence. METHODS This was a cross-sectional epidemiologic study to evaluate rural disparities in ED utilization and quality of care for migraine in the United States in 2019. ED encounter data were collected from the Healthcare Cost and Utilization Project (HCUP) Nationwide Emergency Department Sample (NEDS) and Kentucky State Emergency Department Database (KY-SEDD). The primary outcome was crude and age-adjusted rates of ED encounters for migraine per 10,000 population. ED encounters were included if they had a primary International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis code of G43.xx. ED encounters lacking sufficient data to classify into a geographic group were excluded. Secondary outcomes examined differences in quality of care, including mean ED charges and the proportion of encounters with medication administration, imaging, and nerve block service codes between groups. RESULTS One hundred eighty-three thousand two hundred eleven national ED discharges were classified as rural patient encounters and 627,176 were classified as nonrural. The rural group had significantly higher crude and age-adjusted rates of ED utilization for migraine (crude: rural 39.8, 95% confidence interval [CI] 36.9-42.7; nonrural 22.2, 95% CI 21-23.5 and age-adjusted: rural 41.8, 95% CI 38.8-44.8; nonrural 23.4, 95% CI 22.1-24.7). Opioid utilization was higher in rural encounters (rural n = 26,764, 14.6%; nonrural n = 50,367, 8%; p < 0.001). A Kentucky sub-analysis found 5210 ED discharges were classified as Appalachian and 12,551 as non-Appalachian. The Appalachian group had significantly higher ED utilization rates for migraine compared to the non-Appalachian and national rural groups (crude: Appalachian 44.9, 95% CI 43.7-46.2; age-adjusted: Appalachian 47.4, 95% CI 46.1-48.8). The Kentucky Appalachian group also demonstrated significantly higher opioid analgesia use compared to the national rural group (Appalachian n = 1031, 19.8%; p < 0.001). CONCLUSION This study suggests rural populations, particularly in Appalachia, may experience significantly higher ED utilization for migraine compared to nonrural patients. Moreover, rural populations were more likely to receive suboptimal migraine management with opioid analgesia. Multimodal health-care interventions should be developed to improve access to outpatient migraine care and further investigate potential risk factors in the rural population. With high ED utilization, the Appalachian population may benefit most from such an intervention.

Abstract
BACKGROUND: Migraineurs may be categorized as having episodic migraine (EM: < 15 headache days/month) or chronic migraine (CM: ≥ 15 days/month for > 3 months with ≥ 8 days/month having features of migraine). Opioid use has been linked to progression from EM to CM. OBJECTIVE: To describe the utilization of opioid prescriptions among patients with migraine, to determine the association between opioid use and migraine progression, and to explore demographic and clinical risk factors for migraine progression. METHODS: This retrospective cohort study used Optum's deidentified Clinformatics Data Mart Database from January 2015 to December 2018. Adult patients with a migraine diagnosis and continuous health plan enrollment were included. Opioid use was measured by average daily morphine equivalent dose, also known as morphine milligram equivalent (MME). Descriptive statistics were used to summarize the opioid use by patient demographic and clinical characteristics. A Cox proportional hazards model with stepwise selection was used to determine the risk factors of new-onset CM. RESULTS: Overall, 35% of patients with migraine (27,331 of 78,134) received prescription opioids (> 0 MME/day) during the 12-month follow-up period. Higher opioid dosage was found in patients who had CM and comorbidities of interest. Compared with patients with EM, patients with CM were twice as likely to receive at least 20 MME/day (CM 3.8% vs EM 1.9%) and had a higher median opioid day supply (CM 20 vs EM 10) during follow-up. About 7% of patients with CM with at least 1 opioid prescription had at least 50 MME/day in any 90-day period during follow-up. A significant association was found between MME level and the likelihood of new-onset CM. Additional significant risk factors of migraine progression included younger age, female sex, South and West regions, and having a diagnosis of medication overuse headache, depression, back pain, or fibromyalgia (all P < 0.05). CONCLUSIONS: Despite guidelines and the availability of more migraine-specific treatments, opioids are still commonly prescribed to patients with migraines in real-world practice, especially for those with CM. In this study population, a higher risk of new-onset CM was associated with receiving higher opioid doses.

Trends in the Management of Headache Disorders in US Emergency Departments: Analysis of 2007-2018 National Hospital Ambulatory Medical Care Survey Data. J Clin Med 2022; 11:jcm11051401. [PMID: 35268492 PMCID: PMC8910868 DOI: 10.3390/jcm11051401] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 02/18/2022] [Accepted: 02/28/2022] [Indexed: 12/10/2022] Open
Abstract
We examined trends in management of headache disorders in United States (US) emergency department (ED) visits. We conducted a cross-sectional study using 2007−2018 National Hospital Ambulatory Medical Care Survey data. We included adult patient visits (≥18 years) with a primary ED discharge diagnosis of headache. We classified headache medications by pharmacological group: opioids, butalbital, ergot alkaloids/triptans, acetaminophen/nonsteroidal anti-inflammatory drugs (NSAIDs), antiemetics, diphenhydramine, corticosteroids, and intravenous fluids. To obtain reliable estimates, we aggregated data into three time periods: 2007−2010, 2011−2014, and 2015−2018. Using multivariable logistic regression, we examined medication, neuroimaging, and outpatient referral trends, separately. Among headache-related ED visits, opioid use decreased from 54.1% in 2007−2010 to 28.3% in 2015−2018 (Ptrend < 0.001). There were statistically significant increasing trends in acetaminophen/NSAIDs, diphenhydramine, and corticosteroids use (all Ptrend < 0.001). Changes in butalbital (6.4%), ergot alkaloid/triptan (4.7%), antiemetic (59.2% in 2015−2018), and neuroimaging (37.3%) use over time were insignificant. Headache-related ED visits with outpatient referral for follow-up increased slightly from 73.3% in 2007−2010 to 79.7% in 2015−2018 (Ptrend = 0.02). Reflecting evidence-based guideline recommendations for headache management, opioid use substantially decreased from 2007 to 2018 among US headache-related ED visits. Future studies are warranted to identify strategies to promote evidence-based treatment for headaches (e.g., sumatriptan, dexamethasone) and appropriate outpatient referral and reduce unnecessary neuroimaging orders in EDs.

Abstract
Background Although little is known about why opioid prescribing practices differ between physicians, clinical competence, specialty training and country of origin may play a role. We hypothesised that physicians with stronger clinical competence and communication skills are less likely to prescribe opioids and prescribe lower doses, as do medical specialists and physicians from Asia. Methods Opioid prescribing practices were examined among international medical graduates (IMGs) licensed to practise in the USA who evaluated Medicare patients for chronic pain problems in 2014–2015. Clinical competence was assessed by the Educational Commission for Foreign Medical Graduates (ECFMG) Clinical Skills Assessment. Physicians in the ECFMG database were linked to the American Medical Association Masterfile. Patients evaluated for chronic pain were obtained by linkage to Medicare outpatient and prescription files. Opioid prescribing was measured within 90 days of evaluation visits. Prescribed dose was measured using morphine milligram equivalents (MMEs). Generalised estimating equation logistic and linear regression estimated the association of clinical competence, specialty, and country of origin with opioid prescribing and dose. Results 7373 IMGs evaluated 65 012 patients for chronic pain; 15.2% received an opioid prescription. Increased clinical competence was associated with reduced opioid prescribing, but only among female physicians. For every 10% increase in the clinical competence score, the odds of prescribing an opioid decreased by 16% for female physicians (OR 0.84, 95% CI 0.75 to 0.94) but not male physicians (OR 0.99, 95% CI 0.92 to 1.07). Country of origin was associated with prescribed opioid dose; US and Canadian citizens prescribed higher doses (adjusted MME difference +3.56). Primary care physicians were more likely to prescribe opioids, but surgical and hospital-based specialists prescribed higher doses. Conclusions Clinical competence at entry into US graduate training, physician gender, specialty and country of origin play a role in opioid prescribing practices.

Abstract
Migraine is one of the leading causes of disability worldwide and patients with acute migraine frequently present to emergency departments (ED). The current literature suggests that ED treatment of migraine headache varies across institutions. Considering this, we conducted a scoping review to summarize trends in medication prescribing patterns for acute migraine treatment in the ED setting. Trends were evaluated for factors influencing treatment choices, with particular attention placed on opioids and migraine specific therapy. This scoping review was based on the Arksey and O’Malley methodological framework and included studies published between 1 January 2000 and 31 May 2020. 14 publications met the inclusion criteria. The most common classes of medication prescribed were anti-emetics or Non-steroidal anti-inflammatory drugs (NSAID), but rates varied between studies. There was a concerning trend towards an underutilization of triptans and overutilization of opiates. The use of specific clinical treatment goals (e.g., two-hour pain free freedom response) was also not evident. Additionally, 88% (n = 8) of the nine studies commenting on adherence to hospital or evidence-based guidelines stated that practices were non-adherent. Overall, the reviewed literature reveals treatment practices for acute migraine in the ED are heterogeneous and deviate from established international recommendations.

[PMID: 33599982 DOI: 10.1111/head.14071] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Revised: 12/18/2020] [Accepted: 01/05/2021] [Indexed: 12/12/2022]
Abstract
OBJECTIVE The purpose of this study was to evaluate the subsequent health resource utilization (HRU) between patients with migraine who received opioid medications at their emergency department (ED) visits ("opioid recipients") versus patients with migraine who did not receive opioid medications at their ED visits ("non-recipients"). BACKGROUND Previous studies have found that opioid use is common among patients with migraine at emergency settings. Medication overuse, especially the use of opioids, is associated with migraine progression, which can ultimately lead to substantial health resource use and costs. There is limited evidence on opioid use specifically in emergency settings and its impact on future HRU among people with migraine. METHOD This retrospective cohort study used electronic health record data from the Baylor Scott & White Health between December 2013 and April 2017. Adult patients who had at least 6 months of continuous enrollment before (baseline or pre-index) and after (follow-up) the first date they had an ED visit with a diagnosis of migraine (defined as index date) were enrolled in the study. Opioid use and HRU during follow-up period between opioid recipients and non-recipients were summarized and compared. RESULTS A total of 788 patients met the eligibility criteria and were included in this study. During the 6-month follow-up period, compared to patients with migraine who were non-recipients at their index ED visits, opioid recipients had significantly more all-cause (3.6 [SD = 6.3] vs. 1.9 [SD = 4.8], p < 0.0001) and migraine-related (1.6 [SD = 4.2] vs. 0.6 [SD = 2.1], p < 0.0001) opioid prescriptions (RXs), and more all-cause (2.6 [SD = 4.3] vs. 1.6 [SD = 2.6], p = 0.002) and migraine-related (0.6 [SD = 1.4] vs. 0.3 [SD = 0.8], p = 0.001) ED visits. In addition, opioid recipients had higher risk of future migraine-related ED visits controlling for covariates (HR = 1.49, 95% CI = 1.09-2.03, p = 0.013). Factors that were significantly (p < 0.05) related to future migraine-related ED visits include previous opioid use (HR = 2.12, 95% CI = 1.24-3.65, p = 0.007), previous ED visits (HR = 2.38, 95% CI = 1.23-4.58, p = 0.010), hypertension (HR = 1.46, 95% CI = 1.07-2.00, p = 0.017), age between 45 and 64 years (HR = 0.68, 95% CI = 0.48-0.97, p = 0.033), female sex (HR = 1.82, 95% CI = 1.12-2.86, p = 0.015), and tobacco use disorder (HR = 1.45, 95% CI = 1.07-1.97, p = 0.017). Sub-analyses were restricted to the group of patients who were opioid naïve at baseline (n = 274, defined as having ≤1 opioid RXs during the 6-month pre-index period). Patients who were baseline opioid naïve but received opioids during their index ED visits were more likely to have future migraine-related ED visits compared to patients who were baseline opioid naïve and did not receive any opioids during their index ED visits, controlling for covariates (HR = 2.90, 95% CI = 1.54-5.46, p = 0.001). CONCLUSION Opioid use among patients with migraine presenting to the ED is associated with increased future HRU, which highlights the need for optimizing migraine management in emergency settings.
