Preliminary External Validation Results of the Artificial Intelligence-Based Headache Diagnostic Model: A Multicenter Prospective Observational Study. Life (Basel) 2024; 14:744. [PMID: 38929727 PMCID: PMC11204521 DOI: 10.3390/life14060744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Revised: 06/05/2024] [Accepted: 06/08/2024] [Indexed: 06/28/2024] Open
Abstract
The misdiagnosis of headache disorders is a serious issue, and AI-based headache model diagnoses with external validation are scarce. We previously developed an artificial intelligence (AI)-based headache diagnosis model using a database of 4000 patients' questionnaires in a headache-specializing clinic and herein performed external validation prospectively. The validation cohort of 59 headache patients was prospectively collected from August 2023 to February 2024 at our or collaborating multicenter institutions. The ground truth was specialists' diagnoses based on the initial questionnaire and at least a one-month headache diary after the initial consultation. The diagnostic performance of the AI model was evaluated. The mean age was 42.55 ± 12.74 years, and 51/59 (86.67%) of the patients were female. No missing values were reported. Of the 59 patients, 56 (89.83%) had migraines or medication-overuse headaches, and 3 (5.08%) had tension-type headaches. No one had trigeminal autonomic cephalalgias or other headaches. The models' overall accuracy and kappa for the ground truth were 94.92% and 0.65 (95%CI 0.21-1.00), respectively. The sensitivity, specificity, precision, and F values for migraines were 98.21%, 66.67%, 98.21%, and 98.21%, respectively. There was disagreement between the AI diagnosis and the ground truth by headache specialists in two patients. This is the first external validation of the AI headache diagnosis model. Further data collection and external validation are required to strengthen and improve its performance in real-world settings.

Abstract
BACKGROUND Calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs) are recommended by the United Kingdom National Institute of Health and Care Excellence for the prevention of migraine as treatment beyond third line. We report migraine prevalence and preventive treatment patterns in the adult United Kingdom primary care population over a 7.5-year period, focusing on patients ceasing ≥ 3 oral preventive medication classes. METHODS Study populations were retrieved from the Clinical Practice Research Datalink GOLD database (study period: 19 September 2012 to 1 January 2020; inclusion criteria: ≥12 months follow-up, current-in-dataset, adult on 1 January 2020). Patients who used ≥ 1 oral preventive medication with ≥ 3-year follow-up after first prescription were considered preventive treatment users; class cessation was defined as cessation without evidence of restart within 6 months from end-of-supply date. RESULTS On 1 January 2020, 3.0% of the total study population were diagnosed with migraine (n = 81,190/2,664,306); of these, 42.4% were preventive treatment users (n = 34,448/81,190). The most frequently used oral migraine preventive medication classes were beta-blockers (n = 14,713), tricyclic antidepressants (n = 14,415) and antiepileptics (n = 6497). Among preventive treatment users, 7.7% (n = 2653/34,448) ceased ≥ 3 oral preventive medication classes; of these, 21.7% (n = 576/2653) had been referred to a neurologist. CONCLUSIONS Compared to existing population-based estimates of migraine prevalence, our data further corroborates that a considerable proportion of patients with migraine do not seek treatment. Among those who sought primary care within a 7.5-year period, almost half received empirical oral preventive treatment. Importantly, nearly 1 of 10 preventive treatment users ceased ≥ 3 oral preventive medication classes, highlighting a need for additional therapeutic options. These patients may benefit from CGRP antagonists and/or injectable onabotulinumtoxinA; however, only a minority was referred to specialist care, where these options would be more available.

Treatment Patterns for and Characteristics of Headache in Children and Adolescents Aged 6-17 Years in Japan: A Retrospective Cross-Sectional and Longitudinal Analysis of Health Insurance Claims Data. Life (Basel) 2024; 14:96. [PMID: 38255711 PMCID: PMC10820976 DOI: 10.3390/life14010096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 12/21/2023] [Accepted: 01/06/2024] [Indexed: 01/24/2024] Open
Abstract
OBJECTIVE To investigate the prescription patterns for patients aged 6-17 years with headaches in the REZULT database. METHODS We cross-sectionally investigated (Study 1) the pattern of prescription and the proportion of triptan overprescription (≥30 tablets/90 d of triptans) among patients diagnosed with headaches in 2020. Next, we longitudinally studied patients (Study 2) for more than two years from the initial headache diagnosis (July 2010 to April 2022). The number of prescribed tablets was counted every 90 days. RESULTS In Study 1, headache diagnoses were assigned to 62,568 of 543,628 (11.51%) patients, and 1524 of 62,568 (2.44%) patients received acute medication. Single nonsteroidal anti-inflammatory drugs and triptans were prescribed to 620/624 (99.36%) and 5/624 (0.80%) of patients aged 6-11 years, respectively, and 827/900 (91.89%) and 91/900 (10.11%) of patients aged 12-17 years, respectively. Triptan overprescription was observed in 11/96 (11.46%) patients, and 5/11 (45.45%) of those patients received prophylactic medication. In Study 2, 80,756/845,470 (9.55%) patients aged 6-17 years were diagnosed with headaches that persisted for at least two years. Over two years, 44/80,756 (0.05%) patients were overprescribed triptans, and 3408/80,756 (4.22%) patients were prescribed prophylaxis on at least one occasion. CONCLUSIONS Based on real-world data, the appropriate use of prophylactic treatment is still problematic. Overprescription of triptans was observed, although the number of patients was small.

Abstract
BACKGROUND AND PURPOSE Little is known about the comparative effects of migraine preventive drugs. We aimed to estimate treatment retention and effectiveness of migraine preventive drugs in a nationwide registry-based cohort study in Norway between 2010 and 2020. METHODS We assessed retention, defined as the number of uninterrupted treatment days, and effectiveness, defined as the reduction in filled triptan prescriptions during four 90-day periods after the first preventive prescription, compared to a 90-day baseline period. We compared retention and efficacy for different drugs against beta blockers. Comparative retention was estimated with hazard ratios (HRs), adjusted for covariates, using Cox regression, and effectiveness as odds ratios (ORs) using logistic regression, with propensity-weighted adjustment for covariates. RESULTS We identified 104,072 migraine patients, 81,890 of whom were female (78.69%) and whose mean (standard deviation) age was 44.60 (15.61) years. Compared to beta blockers, botulinum toxin (HR 0.43, 95% confidence interval [CI] 0.42-0.44) and calcitonin gene-related peptide pathway antibodies (CGRPabs; HR 0.63, 95% CI 0.59-0.66) were the least likely to be discontinued, while clonidine (HR 2.95, 95% CI 2.88-3.02) and topiramate (HR 1.34, 95% CI 1.31-1.37) were the most likely to be discontinued. Patients on simvastatin, CGRPabs, and amitriptyline were more likely to achieve a clinically significant reduction in triptan use during the first 90 days of treatment, with propensity score-adjusted ORs of 1.28 (95% CI 1.19-1.38), 1.23 (95% CI 0.79-1.90), and 1.13 (95% CI 1.08-1.17), respectively. CONCLUSIONS We found a favorable effect of CGRPabs, amitriptyline, and simvastatin compared with beta blockers, while topiramate and clonidine were associated with poorer outcomes.

Abstract
OBJECTIVES Migraine and dementia, two major public health challenges, are associated, but more knowledge is needed to understand their relationship. Objectives of this study were to investigate 1) the association between non-self-reported measures of migraine and dementia, and whether dementia was associated with 2) migraine without aura (MO) and with aura (MA) in combination with migraine medication use, and 3) migraine severity operationalized as the number of migraine prescriptions. STUDY DESIGN Matched cohort study. METHODS National register data were obtained from individuals born between 1934 and 1958. Migraine cases (aged 25-58 years) were identified by migraine diagnoses and redeemed migraine medication. Migraine cases were matched with non-cases (N = 340,850) and date of diagnosis or medication redemption was defined as index year. Dementia was identified by dementia diagnoses and redeemed dementia medication. RESULTS We observed a 1.46 (95% CI: 1.26-1.69) times higher dementia rate in individuals with a migraine diagnosis and a 0.86 (95% CI: 0.76-0.97) times lower rate when using migraine medication. We found the highest dementia rate among individuals with MA, who also used migraine medication (HR = 2.23; 95% CI: 1.19-4.17), and the lowest rate among individuals with MO, who also used medication (HR = 1.25; 95% CI: 0.75-2.10). The number of migraine medication prescriptions was not associated with dementia. CONCLUSIONS Being registered with a migraine diagnosis was associated with a higher dementia rate, while use of prescribed migraine medication was not. The differences in the dementia rate among migraine cases identified via diagnoses versus medications warrants further investigation.

Abstract
OBJECTIVES To investigate previous treatment and clinical characteristics in migraine and tension-type headache patients at their first visit to a tertiary headache center. METHODS This was a cross-sectional study using data obtained from electronic questionnaires and medical charts. Migraine and tension-type headache patients were investigated at their first visit to the Danish Headache Center. RESULTS Out of 382 patients the main diagnoses of primary headaches were: 36% with episodic migraine, 43% with chronic migraine, 3% with episodic tension-type headache and 17% with chronic tension-type headache. The majority had attempted non-pharmacological treatment options such as physiotherapy (episodic migraine: 53%, chronic migraine: 68%, episodic tension-type headache: 50%, chronic tension-type headache: 65%) and acupuncture: (episodic migraine: 45%, chronic migraine: 62%, episodic tension-type headache: 17%, chronic tension-type headache: 51%). The majority of migraine patients had tried no more than one triptan (episodic migraine: 71%, chronic migraine: 66%). In total, 35% of episodic migraine and 19% of chronic migraine patients as well as 50% of episodic tension-type headache and 41% of chronic tension-type headache patients had never tried preventive medication. The headache under-response to treatment (HURT) questionnaire score was higher in chronic migraine (score 15) and chronic tension-type headache (score 16) patients than the episodic forms (P < 0.004). CONCLUSIONS Headache patients had attempted several non-pharmacological treatments prior to their first visit at a tertiary headache center in Denmark. The limited use of acute and preventive treatment before the first visit demonstrates a need for better treatment at the primary and secondary care level.

Low adherence to the guideline for the acute treatment of migraine. Sci Rep 2022; 12:8487.

Abstract
The real-world use of triptans in the treatment of migraine is disappointing. Only 12% of the Danish migraine population purchased a triptan between 2014 and 2019, and only 43% repurchased a triptan after first prescription. The aim of the present study was to assess whether physicians and patients adhere to the therapeutic guideline on acute migraine treatment. We interviewed 299 triptan experienced participants with migraine and 101 triptan naïve participants with migraine from the Danish Migraine Population Cohort, using a semi-structured questionnaire. Descriptive statistical analyses were used to study the association with triptan use and the assessed factors. Among triptan naïve participants with migraine, 64% had consulted their general practitioner about their migraine, of whom only 23% received information about the possibility of triptan treatment. Among triptan experienced participants, 77% had only tried one type of triptan. Only 12% could recall they had been informed by their general practitioner to try each triptan three times before giving up. Twenty percent were informed to try three different triptans in total, if the first did not work. In disagreement with the guideline, participants who reported a low pain reduction by a triptan had only tried one type of triptan. Our study shows a low adherence to therapeutic guideline for the attack treatment of migraine. There is a need for better education of general practitioners regarding treatment of migraine. Future campaigns should aim to inform both the public and the general practitioner about antimigraine treatments.

Abstract
OBJECTIVE To characterize nationwide utilization patterns of migraine pharmacotherapy before, during, and after pregnancy in women with triptan use. METHODS Population-based data were obtained by linking the Medical Birth Registry of Norway and the Norwegian Prescription Database from 2006 to 2017. We included 22,940 pregnancies among 19,669 women with at least one filled triptan prescription, a proxy for migraine, in the year before pregnancy or during pregnancy. The population was classified into four groups: i) continuers; ii) discontinuers; iii) initiators, and vi) post-partum re-initiators. Participant characteristics and prescription fills for other drugs such as analgesics, antinauseants, and preventive drugs among the groups were examined, along with an array of triptan utilization parameters. RESULTS In total, 20.0% of the women were classified as triptan continuers, 54.1% as discontinuers, 8.0% as initiators, and 17.6% as re-initiators. Extended use of triptans (≥15 daily drug doses/month) occurred among 6.9% of the continuers in the first trimester. The top 10% of triptan continuers and initiators accounted for 41% (95% CI: 39.2% - 42.5%) and 33% (95% CI: 30.3% - 35.8%) of the triptan volume, respectively. Triptan continuers and initiators had similar patterns of acute co-medication during pregnancy, but use of preventive drugs was more common among the continuers before, during, and after pregnancy. CONCLUSION Among women using triptans before and during pregnancy, one in four continued triptan treatment during pregnancy, and extended triptan use was relatively low. Triptan discontinuation during and in the year after pregnancy was common. Use of other acute migraine treatments was higher among both continuers and initiators of triptans. Women using preventive migraine treatment were most commonly triptan continuers and re-initiators after pregnancy. Prescribing to and counseling of women with migraine should be tailored to the condition severity and their information needs to promote optimal migraine management in pregnancy.

Abstract
BACKGROUND The efficacy of triptans as the main acute treatment strategy for migraine headache at the population-wide level needs to be understood to inform clinical decision-making. We summarise key trends in triptan use using more than 25 years of Danish nationwide data. METHODS We conducted a nationwide register-based cohort study based on all Danish residents with access to public healthcare between 1 January 1994 and 31 October 2019 and summarise informative trends of all purchases of triptans in Denmark in the same period. Complete purchase records of Sumatriptan, Naratriptan, Zolmitriptan, Rizatriptan, Almotriptan, Eletriptan, and Frovatriptan were used. FINDINGS Over a 25-year period, triptan use increased from 345 to 945 defined daily doses (DDD) per 1000 inhabitants per year and the yearly prevalence of triptan use increased from 5.17 to 14.57 per 1000 inhabitants. Between 2014 and 2019, 12.3% of the Danish migraine population purchased a triptan. Following their initial purchase, 43% of patients had not repurchased triptans within 5 years. At most, 10% of patients indicating triptan discontinuation tried more than one triptan. The prevalence of triptan overuse, defined as having purchased at least 20 DDDs of triptans per month for 3 consecutive months, increased in parallel with the prevalence of triptan use, prevalent in 56 of every 1000 triptan users every year between 2014 and 2019. INTERPRETATION In a cohort with access to free clinical consultations and low medication costs, we observed low rates of triptan adherence, likely due to disappointing efficacy and/or unpleasant side effects rather than economic considerations. Triptan success continues to be hindered by poor implementation of clinical guidelines and high rates of treatment discontinuance.

Abstract
OBJECTIVES Prophylactic drugs currently used for migraine treatment are not specific. Furthermore, few studies in existing literature describe drugs utilisation patterns and adherence to migraine prophylactic treatment. This study is aimed to describe utilisation patterns of migraine drugs, evaluate adherence to prophylactic medications and investigate drug-related costs. DESIGN Retrospective population-based study using an administrative health-related database. SETTING Primary care setting in the Campania region, Southern Italy. PARTICIPANTS This study was carried out between 1 January 2016 and 31 December 2018, involving 12 894 subjects with any primary or secondary hospital discharge with migraine diagnosis, or at least two medical dispensations of migraine-specific acute or prophylactic medications (triptans or pizotifen). Subjects were classified into four treatment cohorts: no treatment, acute, prophylactic and both acute and prophylactic. Subjects were followed-up for 1 year. OUTCOME MEASURES Utilisation patterns of migraine drugs at treatment initiation; adherence to prophylactic treatment; discontinuation, restart and switching rates; annual migraine drug costs per patient. RESULTS Overall, 81.1% of subjects received acute treatment as their initial migraine treatment regimen, 10.7% prophylactic treatment, 8.2% both acute and prophylactic treatment. 599 patients were treated prophylactically; of these, 26.2% adhered to their initial treatment while 73.8% reported interruptions in treatment. Among the latter, 46.4% of patients discontinued the treatment completely within 103 days (IQR 89.0), 31% restarted treatment 46 days after interruption (IQR 60.0) and 22.6% switched to another treatment within 98 days (IQR 57.5) (p<0.001). The median annual cost of drugs per patient was €103 for those treated acutely, €75 for those treated prophylactically, €163 for those treated both. CONCLUSIONS Migraine treatment with acute medications is still prevalent in Italy; only few patients received prophylactic treatment with poor adherence to treatment. These findings reflect an unmet need for improved prophylactic therapies in order to provide a better disease management.

Pharmaceutically treated comorbidities and associated healthcare costs among triptan users in Switzerland: A pharmacoepidemiological study from a nationwide health insurance database. Pharmacoepidemiol Drug Saf 2019; 29:279-287. [PMID: 31828875 DOI: 10.1002/pds.4938] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2019] [Revised: 11/05/2019] [Accepted: 11/19/2019] [Indexed: 11/06/2022]
Abstract
PURPOSE In course of the new migraine drug development on the global market it is important to quantify the current burden of migraine medication. This study aimed to estimate the comorbidity burden and its relation to healthcare costs in patients using triptans in Switzerland by analyzing a large population-based database. METHODS This retrospective cohort study was based on Swiss health insurance claims data (2015/2016). The study sample comprised adult patients with ≥1 triptan prescription in 2015. We evaluated pharmaceutically treated comorbid conditions (CCs) and costs (12 months after index prescription) of patients using triptan. Multivariable linear regression models with log-transformed outcomes were performed to identify the factors related to healthcare costs. RESULTS From a total of 749 092, we identified 10,090 patients using triptans (1-year prevalence of 1.35%), whereas 58.9% had ≥2 CCs. The most frequent CCs were pain- and rheumatologic-related diseases and psychological disorders. Among triptan users, the mean total healthcare costs were highest in older patients with ≥2 CCs (>64 years: migraine with ≥2 CC "12 331 SFr"). Multivariate regression analyses showed that psychological disorders had the strongest impact on healthcare costs (Coefficient: 1.29; 95%-CI: 1.27-1.31). CONCLUSIONS The present study provides an overview of comorbidities and its related costs in migraine patients, which helps to quantify the current burden of migraine. This is relevant as the recently licensed CGRP antagonists are likely to change current treatment schemes for migraine, which strongly depends also on the comorbidities. The present study might therefore be helpful for the future development of treatment guidelines.
