“…30 Participants from across Canada reported a wide range of chronic pain conditions. As a result, this study contributes to our knowledge about the relationship between chronic pain and healthcare utilization in Canada beyond what was previously limited to individual diagnoses 9,32 or rural family practice settings. 33 Potential participants were identified through telephone books; thus, the study sample may have included fewer younger individuals who are more likely to rely on mobile telephones.…”

Purpose This study was designed to investigate the role of chronic pain in healthcare visits. The specific objectives were to document the frequency of healthcare visits and to identify characteristics associated with frequent visits. Methods This is a secondary analysis of data from a Canadian cross-sectional study on chronic pain. One thousand two hundred and ninety-four participants were screened for chronic pain, and 741 reported having ''pain or discomfort that had been experienced either all the time or intermittently for at least three months''. Data regarding sociodemographics, general health, and healthcare visits were also collected. The frequency of healthcare visits was defined as at or above the 90th percentile for the group. Frequency was calculated for each setting, i.e., physicians' offices (C 9), emergency departments (C 1), and other (C 15). Binary logistic regression analyses were conducted to identify factors associated with frequent visits.Results Chronic pain increased the frequency of visits to physicians (odds ratio [OR], 4.7; 95% confidence interval [CI], 2.8 to 7.9), emergency departments (OR, 1.4; 95% CI, 1.0 to 2.0), and ''other'' healthcare professionals (OR, 8.3; 95% CI, 4.5 to 15.5). Having C3 chronic conditions significantly increased the odds of frequent healthcare visits. Conclusion Interventions aimed at reducing healthcare costs for chronic pain should target individuals living with multiple chronic conditions. Research is needed to develop and test interventions that focus on the needs of these groups. Identifying the risk factors for high healthcare use and improving self-management may reduce healthcare visits.

Les objectifs spécifiques de l'étude étaient de documenter la fréquence des visites et de déterminer les caractéristiques associées à des visites fréquentes. Méthode Cette étude est une analyse secondaire de données tirées d'une étude canadienne transversale sur la douleur chronique.

Les données sociodémographiques ainsi que celles concernant la santé générale et les visites aux services de soins de santé ont également été colligées. La fréquence des visites aux services de soins de santé a été définie comme étant égale ou au-dessus du 90 e percentile pour le groupe et calculée pour chaque type de service, soit les docteurs et spécialistes (C 9), les départements d'urgence (C 1), et

“…Correspondent expenses for patients with episodic migraine are US$ 1,533.00 and US$ 687.00. There are no data available for Latin America 11 . It is worth mentioning that there are important barriers for investigating and handling headaches in all levels, with lack of governmental policies, little repercussion of information on decision-making levels, sub-notification of the socioeconomic impact of these diseases on the health system, and training of graduation and post-graduation students 2 .…”

Chronic migraine is a condition with significant prevalence all around the world and high socioeconomic impact, and its handling has been challenging neurologists. Developments for understanding its mechanisms and associated conditions, as well as that of new therapies, have been quick and important, a fact which has motivated the Latin American and Brazilian Headache Societies to prepare the present consensus. The treatment of chronic migraine should always be preceded by a careful diagnosis review; the detection of possible worsening factors and associated conditions; the stratification of seriousness/impossibility to treat; and monitoring establishment, with a pain diary. The present consensus deals with pharmacological and nonpharmacological forms of treatment to be used in chronic migraine.

ObjectiveTo describe the development of the Impact of Migraine on Partners and Adolescent Children (IMPAC) scale.BackgroundAlthough existing data and clinical experience suggest that the impact of migraine is pervasive and extends beyond the individual with migraine, no validated tools exist for assessing the impact of migraine on the family.MethodsThe Chronic Migraine Epidemiology and Outcomes (CaMEO) Study is a longitudinal study of people with migraine in the United States. The Family Burden Module (FBM) of the CaMEO Study contained an item pool of 53 questions derived through literature review, clinician input, and patient focus groups pertaining to the following concepts: impact of migraine on family interpersonal relationships, activities, well‐being, finances, and health‐related quality of life. Respondents with migraine (ie, probands) were categorized into 4 groups based on household composition: migraine probands with partners/spouses and children (M‐PC), migraine probands with partners/spouses only (M‐P), migraine probands with child(ren) only (M‐C), and migraine probands without a partner/spouse or child(ren) (M‐O). The IMPAC scale was developed in 3 steps: (1) exploratory factor analysis and item reduction, (2) bifactor analysis, confirmatory factor analysis, and scoring, and (3) reliability and construct validity analyses.ResultsThe analysis of data from 13,064 respondents to the FBM meeting criteria for migraine yielded a 12‐item IMPAC scale, with 4 items applying to all of the groups, 4 more items applying to the groups with partners (M‐P and M‐PC), and 4 additional items to the groups with children (M‐C and M‐PC). Item responses can be summed and converted into a scoring system assessing mild (<0.5 SD below mean; IMPAC scale Grade I), moderate (0.5 SD below to <0.5 SD above mean; Grade II), severe (0.5‐<1.5 SD above mean; Grade III), and very severe (≥0.5 SD above mean; Grade IV) family impact. Test information curves relating to the IMPAC scale for each household type indicated adequate reliability across a large range of family burden severity (from ∼1 SD below to ∼3 SD above mean) and IMPAC scores showed moderate‐to‐large correlations with other validated tools (range, ± 0.38‐0.52), providing support for construct validity.ConclusionsWe developed a questionnaire to assess family burden attributed to migraine that is brief, robust, and psychometrically sound, with a simple scoring algorithm that can be applied to various household compositions. This questionnaire may be valuable in research settings to provide quantifiable data on the impact of migraine on family dynamics and in clinical settings to facilitate conversations about family burden as a target and a motivation for better treatment.

Cost of Health Care Among Patients With Chronic and Episodic Migraine in Canada and the USA: Results From the International Burden of Migraine Study (IBMS)

Abstract: Chronic migraine was associated with higher medical resource use and total costs compared to episodic migraine. Therapies that reduce headache frequency could become important approaches for containing or reducing headache-related medical costs.
