Characterizing barriers to care in migraine: multicountry results from the Chronic Migraine Epidemiology and Outcomes - International (CaMEO-I) study.

ABSTRACT:

Objective

To assess rates of traversing barriers to care to access optimal clinical outcomes in people with migraine internationally.

Background

People in need of medical care for migraine should consult a health care professional knowledgeable in migraine management, obtain an accurate diagnosis, and receive an individualized treatment plan, which includes scientific society guideline-recommended treatments where appropriate.

Methods

The Chronic Migraine Epidemiology and Outcomes-International (CaMEO-I) Study was a cross-sectional, web-based survey conducted from July 2021 through March 2022 in Canada, France, Germany, Japan, the United Kingdom, and the United States (US). Respondents who met modified International Classification of Headache Disorders, 3rd edition, criteria for migraine and had Migraine Disability Assessment Scale (MIDAS) scores of ≥ 6 (i.e., mild, moderate, or severe disability) were deemed to need medical care and were included in this analysis. Minimally effective treatment required that participants were currently consulting a health care professional for headache (barrier 1), reported an accurate diagnosis (barrier 2), and reported use of minimally appropriate pharmacologic treatment (barrier 3; based on American Headache Society 2021 Consensus Statement recommendations). Proportions of respondents who successfully traversed each barrier were calculated, and chi-square tests were used to assess overall difference among countries.

Results

Among 14,492 respondents with migraine, 8,330 had MIDAS scores of ≥ 6, were deemed in need of medical care, and were included in this analysis. Current headache consultation was reported by 35.1% (2926/8330) of respondents. Compared with the US, consultation rates and diagnosis rates were statistically significantly lower in all other countries except France where they were statistically significantly higher. Total appropriate treatment rates were also statistically significantly lower in all other countries compared with the US except France, which did not differ from the US. All 3 barriers were traversed by only 11.5% (955/8330) of respondents, with differences among countries (P < 0.001).

Conclusions

Of people with migraine in need of medical care for migraine, less than 15% traverse all 3 barriers to care. Although rates of consultation, diagnosis, and treatment differed among countries, improvements are needed in all countries studied to reduce the global burden of migraine.

Project description:BackgroundLongitudinal migraine studies have rarely assessed headache frequency and disability variation over a year.MethodsThe Chronic Migraine Epidemiology and Outcomes (CaMEO) Study is a cross-sectional and longitudinal Internet study designed to characterize the course of episodic migraine (EM) and chronic migraine (CM). Participants were recruited from a Web-panel using quota sampling in an attempt to obtain a sample demographically similar to the US population. Participants who passed the screener were assessed every three months with the Core (baseline, six, and 12 months) and Snapshot (months three and nine) modules, which assessed headache frequency, headache-related disability, treatments, and treatment satisfaction. The Core also assessed resource use, health-related quality of life, and other features. One-time cross-sectional modules measured family burden, barriers to medical care, and comorbidities/endophenotypes.ResultsOf 489,537 invitees, we obtained 58,418 (11.9%) usable returns including 16,789 individuals who met ICHD-3 beta migraine criteria (EM (<15 headache days/mo): n = 15,313 (91.2%); CM (≥ 15 headache days/mo): n = 1476 (8.8%)). At baseline, all qualified respondents (n = 16,789) completed the Screener, Core, and Barriers to Care modules. Subsequent modules showed some attrition (Comorbidities/Endophenotypes, n = 12,810; Family Burden (Proband), n = 13,064; Family Burden (Partner), n = 4022; Family Burden (Child), n = 2140; Snapshot (three months), n = 9741; Core (six months), n = 7517; Snapshot (nine months), n = 6362; Core (12 months), n = 5915). A total of 3513 respondents (21.0%) completed all modules, and 3626 (EM: n = 3303 (21.6%); CM: n = 323 (21.9%)) completed all longitudinal assessments.ConclusionsThe CaMEO Study provides cross-sectional and longitudinal data that will contribute to our understanding of the course of migraine over one year and quantify variations in headache frequency, headache-related disability, comorbidities, treatments, and familial impact.

Project description:ObjectivesWe examined the cross-sectional association of sleep apnea and indices of sleep quality with both episodic migraine (EM) and chronic migraine (CM).BackgroundSleep apnea and abnormal patterns of sleep, such as insomnia, were associated with migraine onset, severity, and progression in previous research.MethodsThe Chronic Migraine Epidemiology & Outcomes Study, a longitudinal study, used a series of web-based surveys to assess migraine symptoms, burden, and patterns of health care utilization. Quota sampling was used from September 2012 to November 2013 to generate a representative sample of the US population. Persons who screened positive for sleep apnea on the Berlin Questionnaire are said to be at "high risk" for sleep apnea. Respondents indicated if they believed that they had sleep apnea, if a physician had diagnosed it, and if and how they were treated. Other aspects of sleep quality were assessed using the Medical Outcomes Study (MOS) Sleep Measures.ResultsOf 12,810 eligible respondents with migraine and data on sleep, 11,699 with EM (91.3%) and 1111 with CM (8.7%) provided valid data for this analyses. According to the Berlin Questionnaire, 4739/12,810 (37.0%) were at "high risk" for sleep apnea, particularly persons with CM vs EM (575/1111 [51.8%] vs 4164/11,699 [35.6%]), men vs women (1431/3220 [44.4%] vs 3308/9590 [34.5%]), people with higher body mass index, and older people (all P < .001). Among respondents to the MOS Sleep Measures, persons with CM were more likely to report poor sleep quality than those with EM, including sleep disturbance (mean [SD] values: 53.2 [26.9] vs 37.9 [24.3]), snoring (38.0 [33.9] vs 31.0 [32.1]), shortness of breath (34.9 [29.8] vs 15.3 [20.6]), somnolence (44.1 [23.4] vs 32.2 [21.2]), and less likely to report sleep adequacy (34.0 [24.2] vs 39.2 [22.1]).ConclusionsCompared with respondents with EM, a larger proportion of those with CM were at "high risk" for sleep apnea and reported poor sleep quality. This reflects an association between CM vs EM and sleep apnea and poor sleep quality; the potential relationships are discussed.

Project description:OBJECTIVE:This analysis assessed migraine-related burden and treatment decisions in Chronic Migraine Epidemiology and Outcomes (CaMEO) Study survey respondents who stopped taking acute prescription medications for migraine. BACKGROUND:Migraine is a common yet underdiagnosed and undertreated neurological disease often associated with significant disability. Acute prescription medications are underused, in part because patients discontinue treatment. Rates and reasons for discontinuing acute prescription medications require exploration. METHODS:The CaMEO Study is a longitudinal, Internet-based survey that identified and followed people who met modified ICHD-3 migraine criteria. For this analysis, eligible respondents had used acute prescription medication for migraine in the past but no longer used or kept these treatments on hand (discontinued users). Respondents who reported discontinuing acute prescription treatment answered questions about length of time since last use and reasons for stopping. Reasons for discontinuing were thematically summarized. Monthly headache day frequency, Migraine Disability Assessment (MIDAS), Patient Health Questionnaire 9-item depression screener, Generalized Anxiety Disorder 7-item screener, and the 12-item Allodynia Symptom Checklist were also assessed. RESULTS:Of 13,624 respondents with migraine, 4840 (35.5%) had ever used acute prescription medications and 1719 (35.5%) of those were discontinued users. Discontinued users had a mean (SD) age of 42.1 (14) years, and 1348/1719 (78.4%) were female. Monthly headache frequency of 0-4 days was reported by 1073/1719 (62.4%) of respondents, 5-9 days by 322/1719 (18.7%), 10-14 days by 135/1719 (7.9%), and ≥15 days by 189/1719 (11.0%). Two-thirds (1160/1719 [67.5%]) of discontinued users reported a receiving migraine (or chronic migraine) diagnosis from a doctor or other health professional in the past. Although all had spoken to a doctor about their headaches, 1504/1719 (87.5%) had stopped having their headaches managed or treated by a doctor for at least 12 months. Only 1 in 5 discontinued users reported being able to work or function normally with a headache, and 717/1719 (41.7%) had moderate to severe disability (MIDAS). Among the most commonly reported reasons for prescription medication discontinuation were switching to non-prescription pain medication (782/1719 [45.5%]), as well as concerns about prescription medication efficacy (484/1719 [28.2%]) and tolerability (428/1719 [24.9%]). Nearly half of respondents who reported either efficacy or tolerability concerns had moderate to severe disability. CONCLUSIONS:People with migraine who discontinue acute prescription medication have a high level of unmet treatment need. The majority cannot work or function normally with headaches, with 646/1719 (37.6%) of discontinued users reporting 5 or more headache days per month.

Project description:ObjectiveTo examine the influences of depression and anxiety on headache-related disability in people with episodic migraine or chronic migraine.BackgroundDepression and anxiety are common comorbidities in people with migraine, especially among those with chronic migraine.MethodsThis cross-sectional analysis of data from the longitudinal, internet-based Chronic Migraine Epidemiology and Outcomes Study assessed sociodemographic and headache features, and headache-related disability (Migraine Disability Assessment Scale). Four groups were defined based on scores from validated screeners for depression (9-item Patient Health Questionnaire) and anxiety (7-item Generalized Anxiety Disorder Scale): depression alone, anxiety alone, both, or neither.ResultsRespondents (N = 16,788) were predominantly women (74.4% [12,494/16,788]) and white (84.0% [14,044/16,788]); mean age was 41 years. Depression was more likely in persons with chronic migraine vs episodic migraine (56.6% [836/1476] vs 30.0% [4589/15,312]; P < .001), as were anxiety (48.4% [715/1476] vs 28.1% 4307/15,312]; P < .001) and coexisting depression and anxiety (42.0% [620/1476] vs 20.8% [3192/15,312]; P < .001). After controlling for headache frequency and other covariates, depression alone, and anxiety alone were associated with 56.0% (rate ratio [RR], 1.56; 95% confidence interval [CI], 1.46-1.66) and 39.0% (RR, 1.39; 95% CI, 1.30-1.50) increased risks of moderate/severe migraine-related disability (both P < .001), respectively; the combination had an even greater effect on risk of moderate/severe disability (79.0% increase; RR, 1.79; 95% CI, 1.71-1.87; P < .001).ConclusionsDepression alone and anxiety alone are associated with greater headache-related disability after controlling for sociodemographic and headache features. Coexisting depression and anxiety are more strongly associated with disability than either comorbidity in isolation. Interventions targeting depression and anxiety as well as migraine itself may improve headache-related disability in people with migraine.

Project description:ObjectiveTo assess the effects of migraine on important life domains and compare differences between respondents with episodic and chronic migraine and between sexes.BackgroundMigraine is associated with a substantial personal and societal burden and can also affect the interpersonal dynamics, psychological health and well-being, and financial stability of the entire family of the person with migraine.MethodsThe Chronic Migraine Epidemiology and Outcomes (CaMEO) Study is a prospective, longitudinal, Web-based survey study undertaken between September 2012 and November 2013 in a systematic U.S. sample of people meeting modified International Classification of Headache Disorders, 3rd edition migraine criteria: 19,891 respondents were invited to complete the Family Burden Module, which assessed the perceived impact of migraine on family relationships and life, career and finances, and overall health. Respondents were stratified by episodic migraine (<15 headache days/month) and chronic migraine (≥15 headache days/month) and sex for comparisons.ResultsA total of 13,064 respondents (episodic migraine: 11,944 [91.4%]; chronic migraine: 1120 [8.6%]) provided valid data. Approximately 16.8% of respondents not currently in a romantic relationship (n = 536 of 3189) and 17.8% of those in a relationship but not living together (n = 236 of 1323) indicated that headaches had contributed to relationship problems. Of those in a relationship and living together (n = 8154), 3.2% reported that they chose not to have children, delayed having children or had fewer children because of migraine (n = 260; episodic migraine: n = 193 of 7446 [2.6%]; chronic migraine: n = 67 of 708 [9.5%]; P < .001). Of individuals responding to career/finance items (n = 13,061/13,036), 32.7% indicated that headaches negatively affected ≥1 career area (n = 4271; episodic migraine: n = 3617 of 11,942 [30.3%]; chronic migraine: n = 654 of 1119 [58.4%]), and 32.1% endorsed worry about long-term financial security due to migraine (n = 4180; episodic migraine: n = 3539 of 11,920 [29.7%]; chronic migraine: n = 641 of 1116 [57.4%]).ConclusionsMigraine can negatively affect many important aspects of life including marital, parenting, romantic and family relationships, career/financial achievement and stability, and overall health. Reported burden was consistently greater among those with chronic migraine than among people with episodic migraine; however, few differences were seen between the sexes.

Project description:ObjectiveTo compare the methods and baseline characteristics of the American Migraine Prevalence and Prevention (AMPP) and Chronic Migraine Epidemiology and Outcomes (CaMEO) studies.BackgroundThe AMPP and CaMEO studies are the largest longitudinal efforts designed to improve our understanding of episodic and chronic migraine in the United States. The studies have complementary strengths and weaknesses.MethodsThis analysis compares and contrasts the study methods and participation rates of the AMPP and CaMEO studies. We then compare and contrast baseline results in terms of demographic characteristics, headache features, and disability as measured by the Migraine Disability Assessment Scale (MIDAS) among people with episodic and chronic migraine.ResultsAMPP and CaMEO sampled from panels constructed to be representative of the US population. The AMPP Study collected data using a mailed questionnaire while CaMEO relied on a web survey methodology. Response rates were higher in AMPP (64.8%) than in CaMEO (16.5%). Both studies assessed headache features using the American Migraine Study/AMPP diagnostic module. Both identified persons with episodic (<15 headache days/month) and chronic migraine (≥15 headache days/month) based on the International Classification of Headache Disorders. AMPP collected data annually over 5 years, while CaMEO collected data quarterly over 15 months. Baseline demographic distribution was generally similar, indicating that each study was broadly representative of the US population. The proportion of persons with migraine who had chronic migraine was similar (AMPP, 6.6%; CaMEO, 8.8%). Respondents had similar median headache frequency (days/month) by sex for chronic migraine (AMPP: men = 21.7, women = 20.0; CaMEO: men = 20.0, women = 20.0) and episodic migraine (AMPP: men = 1.7, women = 2.0; CaMEO: men = 2.0, women = 3.0). Median MIDAS scores were substantially higher in both studies for chronic migraine (severe disability [Grade IV]; AMPP: men = 33.0, women = 45.0; CaMEO: men = 32.0, women = 38.0) than episodic migraine (little/mild disability [Grade I/II]; AMPP: men = 3.0, women = 6.0; CaMEO: men = 4.0, women = 7.0). Rates of moderate/severe disability (Grade III/IV) were substantially higher in both studies for chronic migraine (AMPP: men = 66.9%, women = 78.9%; CaMEO: men = 71.0%, women = 82.6%) than episodic migraine (AMPP: men = 23.0%, women = 31.8%; CaMEO: men = 26.7%, women = 37.9%). More women than men respondents in both studies experienced moderate/severe disability.ConclusionsAMPP and CaMEO are longitudinal cohort studies that used different methods, but yielded similar results for demographic features, headache frequency, and headache-related disability. Both studies found more severe headache-related disability in those with chronic versus episodic migraine.
