Reducing the physical, social, and emotional impact of episodic migraine: Results from erenumab STRIVE and ARISE phase III randomized trials.

OBJECTIVE: The purpose of this study was to examine changes in the functional impact of migraine following treatment with erenumab, as measured by the Migraine Functional Impact Questionnaire (MFIQ). BACKGROUND: The MFIQ, a novel patient-reported outcome (PRO) measuring the impact of migraine on four domains (physical function, social function, and emotional function [PF, SF, and EF]; usual activities [UAs]) and a single item assessing overall impact on UA, was included in phase III trials evaluating erenumab 70 and 140 mg monthly for migraine prevention among people with episodic migraine (EM). METHODS: In the ARISE study, 577 patients with EM were randomized to erenumab 70 mg or placebo. In the STRIVE study, 955 patients with EM were randomized to erenumab, 70 mg or 140 mg or placebo. Pairwise comparisons of least-squares mean (LSM) change from baseline in MFIQ scores (with associated 95% confidence interval [CI]) were assessed for each active treatment versus placebo. RESULTS: In ARISE, greater reductions from baseline to month 3 were observed for 70 mg versus placebo for PF (LSM [95% CI]: -3.2 [-6.4 to -0.1]; p = 0.046) and EF (-4.0 [-7.3 to -0.7]; p = 0.019) domain scores. In STRIVE, between-group differences also reflected reductions from baseline to the average of months 4-6 that favored erenumab on all four MFIQ domain scores. Reductions in impact for 70 mg compared to placebo were -4.3 (95% CI: -6.8 to -1.7; p < 0.001) for PF, -4.0 (-6.3 to -1.7; p < 0.001) for UA, -3.7 (-6.1 to -1.2; p = 0.003) for SF, and -5.3 (-7.9 to -2.6; p < 0.001) for EF domain scores. Improvements were also observed for 140 mg versus placebo with between-group differences of -5.7 (95% CI: -8.2 to -3.2; p < 0.001) in PF, -5.1 (-7.5 to -2.8; p < 0.001) in UA, -5.0 (-7.4 to -2.6; p < 0.001) in SF, and -7.2 (-9.9 to -4.5; p < 0.001) in EF domain scores. There were also greater improvements in the overall impact on UA score for 70 mg (LSM [95% CI]: -4.3 [-7.0 to -1.7]; p = 0.001) and 140 mg (-5.3 [-8.5 to -3.2]; p < 0.001) versus placebo. CONCLUSIONS: The MFIQ measures the frequency of impacts and level of difficulty on multiple functional domains that provide a more complete picture of the effects of migraine. MFIQ scores showed that in comparison with placebo, patients treated with erenumab had greater reductions in the functional impact of migraine, providing insight into treatment benefits that extend beyond improvements in clinical status and health-related quality of life previously reported based on clinical end points and other PROs.

Understanding the migraine treatment landscape prior to the introduction of calcitonin gene-related peptide inhibitors: Results from the Assessment of TolerabiliTy and Effectiveness in MigrAINe Patients using Preventive Treatment (ATTAIN) study.

BACKGROUND: Calcitonin gene-related peptide (CGRP) inhibitors were introduced in the United States (US) in 2018. To understand the changing patterns of preventive treatment following the introduction of these new agents, we must first characterize the patterns which preceded their introduction. OBJECTIVE: To characterize the burden, unmet need, and treatment patterns in patients with migraine initiating preventive migraine medications before the introduction of CGRP inhibitors in the US. METHODS: Between March 2016 and October 2017, we enrolled episodic (EM) and chronic migraine (CM) patients initiating or changing preventive treatment at primary care or neurology clinic visits in the US, in a real-world observational study using a prospective cohort design. At baseline and monthly thereafter for 6 months, we collected data from study sites and patients on migraine frequency, treatment modifications, migraine impact on functioning, and work productivity for a descriptive analysis of migraine patient experience and treatment patterns. RESULTS: From the sample of 234 completers, 118 had EM (50.4%) and 116 had CM (49.6%). Mean age at enrollment was 41 years (SD = 12) and mean age at first migraine diagnosis was 22 years (SD = 11). Most participants were females (n = 204/234; 87.2%) and white (n = 178/234; 76.1%). The majority (n = 164/234; 70.1%) had not used preventive migraine treatment in the 5 years prior to enrollment (treatment naïve). At baseline, mean monthly migraine days were 9.6 days (SD = 5.0) for the preventive treatment naïve group and 12.4 days (SD = 7.0) for treatment experienced patients. The majority had severe Migraine Disability Assessment (Grade IV, total score ≥21), including 67.1% (n = 110/164) of the preventive treatment naïve and 77.1% (n = 54/70) of the preventive treatment experienced patients. Headache Impact Test total scores indicating severe impairment (score >59) occurred in 88.4% (n = 145/164) of the treatment naïve and 88.6% (n = 62/70) of treatment experienced patients. Mean work productivity loss as measured by the Work Productivity and Activity Impairment questionnaire in the subsample of employed patients was 53.3% loss. The most used acute medications at baseline were nonsteroidal anti-inflammatory agents (n = 124/234; 53.0%), acetaminophen-based products (n = 112/234; 47.9%), and triptans (n = 105/234; 44.9%). The most commonly initiated preventive treatments were topiramate (n = 100/234; 42.7%), tricyclic antidepressants (n = 39/234; 16.7%), beta-blockers (n = 26/234; 11.1%), and onabotulinumtoxinA (n = 24/234; 10.3%). Over the 6-month follow-up period, almost half of patients (n = 116/234, 49.6%) modified their preventive treatment and discontinued treatment (n = 88/312 total modifications; 28.2%) or modified their pattern of use by increasing, decreasing, or skipping doses (n = 224/312 total modifications; 71.8%), often without seeking medical advice. Avoiding side effects was the main reason reported among patients who discontinued (n = 52/88; 59.1%), decreased frequency or dose (n = 37/89; 41.6%), and skipped doses (n = 29/86; 33.7%). Perceived lack of efficacy was another frequent reason reported among those who discontinued (n = 20/88; 22.7%), decreased frequency or dose (n = 15/89; 16.9%), and skipped doses (n = 18/86; 20.9%). Despite initiation of preventive treatment and improvements observed in number of headache and migraine days, migraine patients continued to experience substantial disability, headache impact, and reduced productivity throughout the 6-month follow-up period. CONCLUSIONS: Prior to 2018, the burden of migraine was high for patients initiating preventive treatments. Despite having more than 9 days of migraine per month on average, the majority (70.1%) of patients initiating prevention had been treatment naïve, indicating underuse of preventive treatments. The preventive treatments used in this study were poorly tolerated and were reported by patients to lack efficacy, resulting in suboptimal adherence. The high discontinuation rates suggest that the preventive medications being offered during the period of the study did not meet the treatment needs of patients. In addition, the decisions by about half of patients to alter their prescribed treatment plan without consulting their provider can pose substantial health risks. These findings pertain to the broad set of preventive treatments initiated in this study and do not support inferences about individual preventive treatments, due to limitations in sample size. These findings suggest the need for more effective and better tolerated preventive treatment options.

Evaluating the Psychometric Properties of the Migraine Functional Impact Questionnaire (MFIQ).

BACKGROUND: Migraine is a chronic neurologic disease that can be associated with significant migraine-related impact, disability, and burden. Patient-reported outcome measures (PRO) are included in clinical trials of migraine interventions to capture treatment effects from a patient perspective. Clinical and regulatory guidelines also encourage use of PROs in trials. The Migraine Functional Impact Questionnaire (MFIQ) is a novel PRO measure, assessing the impact of migraine on Physical Function (PF), Usual Activities (UA), Social Function (SF), and Emotional Function (EF), in the past 7 days. Scientific methods recommended to meet the requirements of the U.S. Food and Drug Administration were followed, to ensure that the MFIQ content included outcomes that were relevant to adults with migraine and were clinically relevant, specifically to evaluate preventive treatments for migraine. OBJECTIVE: The objective of this study was to conduct item analyses informing item reduction and scoring, and to evaluate the psychometric properties of the MFIQ. METHODS: In a prospective, observational study, adults with migraine completed the MFIQ as well as additional clinical and PRO instruments, including the Headache Impact Test (HIT-6TM ), Patient-Reported Outcomes Measurement Information System Physical Function Short Form 10a (PROMIS-PF), Migraine-Specific Quality-of-Life Questionnaire (MSQ), and Patient Global Rating of Change (PGIC). Item-level evaluation, item response theory (IRT), and factor analysis were used to select final MFIQ items, identify domains, and inform scoring. Psychometric properties of the MFIQ were evaluated to assess reliability (internal consistency and test-retest), validity (construct and known-groups), and responsiveness. RESULTS: The study enrolled 569 adults with migraine. Subjects had an average age of 39.9 years (SD 12.0), 87.2% were female, and 80.8% were white. Five items were dropped from the draft version based on results of item-level analyses reviewed in the context of previous qualitative research to produce the final 26-item MFIQ (v.2). Four domain scores (PF, UA, SF, and EF) and a global item score for impact on UA were identified. Higher scores on a 0-100 scale represent greater impact. All scores exhibited high internal consistency (α ≥ 0.89) and moderate test-retest reliability among stable subjects (ICCs ≥ 0.47). Construct validity was demonstrated by significant correlations (all P < .0001) between MFIQ domain scores, related PRO scores, and the frequency of migraine days and headache days. All domain scores differentiated between subgroups ("known groups") defined based on established levels of clinical severity: number of monthly migraine and headache days, migraine interference levels and scores on other PRO instruments (P < .05). Improvements in MFIQ scores corresponded with clinical improvement (percent reduction in monthly migraine days), improvement in migraine interference with daily activities, and related improvements in PRO scores (P < .05), demonstrating that the MFIQ was responsive to changes in migraine impact. CONCLUSIONS: The MFIQ is a reliable and valid measure that can be used to collect data about migraine impact. The MFIQ is being used to evaluate outcomes of migraine interventions in clinical trials and observational studies. It could potentially also be used in clinical practice both for initial and ongoing assessments for monitoring outcomes and to enhance communication between patients and healthcare professionals for the management of migraine.

Psychometric Evaluation of a Novel Instrument Assessing the Impact of Migraine on Physical Functioning: The Migraine Physical Function Impact Diary.

OBJECTIVE: The objective of this study was to evaluate the measurement properties of the Migraine Physical Function Impact Diary (MPFID), a novel patient-reported outcome (PRO) measure for assessing the impact of migraine on physical functioning. METHODS: In a prospective, observational study, adults with episodic migraine (EM) or chronic migraine (CM) used an eDiary to complete the MPFID (assessing daily impacts of migraine on physical function) and a headache diary (capturing migraine days, migraine pain intensity, and migraine interference) each day, and other PRO instruments related to migraine. Item-level evaluation, item response theory (IRT), and exploratory factor analysis (EFA) methods were applied to identify domains, select final MPFID items, and develop scoring procedures. Psychometric properties of the final 13-item MPFID were evaluated using confirmatory factor analysis and tests of reliability (Cronbach's α for internal consistency and intra-class correlation [ICC] for test-retest) and validity (convergent and known-groups). RESULTS: The study enrolled 569 adults with chronic or episodic migraine, mean (SD) age 39.9 (12.0) years and 87.2% female. Item-level analyses based on interim data informed selection of a set of 13 items for the MPFID, through evaluation of floor/ceiling effects, item-to-item correlations, factor loadings, and IRT-based fit/misfit statistics. Two domain scores (EA: Impact on Everyday Activities; PI: Physical Impairment) and a global item score for impact on everyday activities were identified. EA and PI domains exhibited high internal consistency (α = 0.97; α = 0.93) and good test-retest reliability among stable subjects (ICCs = 0.74 and 0.77). Convergent validity was demonstrated by moderate correlations (r = ±0.50-0.68; P < .0001) between MPFID domain scores and number of migraine days, headache days, bed days, and other migraine-related PRO instruments. EA and PI scores differentiated between groups who varied by number of migraine days, migraine interference levels, migraine pain intensity, and median split groups of scores based on other PROs instruments (P < .05). CONCLUSIONS: The MPFID has robust psychometric properties (ie, reliability and validity). Findings supported two distinct domains about the impact of migraine on physical functioning: Impact on Everyday Activities and Physical Impairment. Both domain scores showed evidence of excellent reliability and construct validity in assessing the impacts of migraine on physical functioning.

Impact of female acne on patterns of health care resource utilization.

BACKGROUND: Limited data are available on acne treatment patterns in females through their adult years. OBJECTIVE: The purpose of this analysis was to evaluate health care resource utilization (HRU) and treatment patterns in cohorts with and without the use of acne medication and predictors of use. METHODS: A cross-sectional, web-based survey was administered to US females (25-45 years) with facial acne (≥ 25 visible lesions). Data collected included: sociodemographics and self-reported clinical characteristics, acne treatments, and health care professional (HCP) visits. Subject characteristics associated with medication use were examined by logistic regression. RESULTS: Approximately half of the total sample (N=208, mean age: 35 ± 6) ever visited an HCP for acne and reported more over-the counter (OTC) medication use (51.0%) than prescription (Rx) medication use (15.4%). Subjects did not use medications daily, averaging from 12-18 days over the previous 4 weeks. Logistic regression showed that race and prior HCP visits for acne were significant predictors of medication use (P<.05). CONCLUSIONS: Adult females generally self-treated their acne using primarily OTC medications; however, poor compliance was observed for Rx and OTC. Race and prior HCP visits for acne were significant predictors of current medication use.

Meaningful Within-Patient Change in Subjective Total Sleep Time in Patients with Insomnia Disorder: An Analysis of the Sleep Diary Questionnaire Using Data from Open-Label and Phase III Clinical Trials.

BACKGROUND: The Sleep Diary Questionnaire (SDQ), a modified version of the Consensus Sleep Diary, is a 17-item sleep diary for assessing subjective total sleep time (sTST: total time spent asleep at night) and other sleep parameters in insomnia trials. sTST is a key parameter of efficacy in insomnia trials; however, the magnitude of improvement in this parameter that people with insomnia disorder consider clinically meaningful is unclear. OBJECTIVE: The aim of this study was to estimate meaningful within-patient change for sTST using clinical trial data. METHODS: Data were from an open-label trial of zolpidem and pooled data from a phase III placebo-controlled trial of daridorexant. In both trials, adults with moderate to severe insomnia completed the SDQ daily. Meaningful change in sTST was estimated in an anchor-based analysis using outcome measures that were correlated with change in weekly average sTST (Spearman correlation coefficient ≥ 0.30): the Insomnia Severity Index, patient global assessments and impressions of severity and change in daytime and night-time symptoms (PGA-S, PGI-S, PGI-C), and clinician global impressions of severity and change in patients' daytime symptoms (CGI-S, CGI-C). Meaningful within-patient change estimates were 'triangulated' to identify a value where they converged. RESULTS: In the open-label trial (N = 114), subjects with a 1-point or 1-step improvement on the anchors had mean increases in sTST of 60.1-83.2 min at day 8 and 55.5-68.2 min at day 15. For subjects with a 2-point or 2-step improvement on the anchors, mean increases in sTST were 79.6-81.4 min at day 8 and 80.1-93.5 min at day 15. In the phase III trial (N = 930), weekly average increases in sTST for subjects with a 1-point or 1-step improvement on the anchors were 39.3-46.7 min at month 1 and 47.3-58.3 min at month 3. For subjects with a 2-point or 2-step improvement on the anchors, mean increases in sTST were 60.7-76.2 min at month 1 and 70.1-87.7 min at month 3. Triangulation of these values supported a meaningful within-patient change threshold starting at 55 min. CONCLUSION: Increasing sTST is an important treatment outcome for people with insomnia. An increase in sleep time of approximately 55 min is meaningful to patients. CLINICAL TRIALS REGISTRATION: NCT03056053 (17 February 2017) and NCT03545191 (4 June 2018).

Patterns of use and reasons for discontinuation of prophylactic medications for episodic migraine and chronic migraine: results from the second international burden of migraine study (IBMS-II).

OBJECTIVE: Our objective was to characterize patterns of preventive medication use in persons with episodic migraine (EM) and chronic migraine (CM). BACKGROUND: Several classes of medications are used both on- and off-label for the prevention of migraine, including ß-blockers (eg, propranolol, timolol), tricyclic antidepressants (eg, amitriptyline), anti-epileptic drugs (eg, topiramate, valproic acid), and neurotoxins (eg, onabotulinumtoxinA). METHODS: Preventive medication use and reasons for discontinuation were collected in an international, Web-based, cross-sectional survey of adults with migraine during 2010. Descriptive analyses were conducted on demographics and headache-related disability as measured by the Migraine Disability Assessment Scale, stratified by use of preventive medication, and EM or CM. Univariate and multivariate logistic regression models were constructed to assess predictors of preventive medication use. RESULTS: One thousand one hundred and sixty-five respondents completed the survey. Only 28.3% of EM and 44.8% of CM respondents were currently using preventive medication; any use of prophylaxis (prior or current) was reported by 43.4% of those with EM and 65.9% with CM. The mean number of prophylactic medications ever used was 2.92 for EM and 3.94 for CM. Antidepressants were used most frequently (EM 60.9%; CM 54.7%), followed by ß-blockers (EM 35.4%; CM 36.8%) and anti-epileptics (EM 28.6%; CM 36.3%). Odds of preventive medication use were higher among CM than EM, adjusting for age, gender, race, years of daily headache, and country (odds ratio 2.72; 95% confidence interval 2.15 to 3.57). Greater headache-related disability and older age were also associated with greater odds of ever having used prophylaxis, regardless of headache frequency. CONCLUSIONS: Less than half the persons with EM and CM were currently using preventive medication for migraine, with treatment rates being higher for CM, as expected. Those with CM tried more medications than those with EM, possibly reflecting higher levels of treatment need.

Meaningful Within-Patient Change on the Insomnia Daytime Symptoms and Impacts Questionnaire (IDSIQ): Analysis of Phase III Clinical Trial Data of Daridorexant.

BACKGROUND: The Insomnia Daytime Symptoms and Impacts Questionnaire (IDSIQ) is a new validated 14-item patient-reported outcome (PRO) instrument for evaluating daytime functioning in people with insomnia. It comprises three domains: Alert/Cognition, Mood, and Sleepiness. OBJECTIVE: The aim of this analysis was to estimate the minimum within-patient change for IDSIQ scores that an adult patient with insomnia would consider meaningful. METHODS: Data were from a randomized, double-blind, placebo-controlled, phase III clinical trial of daridorexant in adults with insomnia. Subjects completed the IDSIQ daily in the evening, with a recall period of 'today', throughout the 3-month double-blind treatment period. Scores were calculated as a weekly average. Each IDSIQ item was scored on an 11-point numeric rating scale ranging from 0 (not at all/none at all) to 10 (very/a lot), with a higher score indicating a greater severity or impact. PRO measures with correlation coefficients ≥0.30 were included in a subsequent anchor-based analysis. For the IDSIQ total score and each IDSIQ domain, meaningful within-patient change was estimated as the minimum score change patients would consider meaningful in an anchor-based analysis using data from PRO instruments capturing daytime and night-time insomnia symptoms (the Insomnia Severity Index [four items, each scored 0-4, with a higher score indicating greater symptom severity; assessed at screening, baseline, month 1 and month 3], Patient Global Assessment of Disease Severity [6-point scale from 'none' to 'very severe'; assessed weekly], Patient Global Impression of Severity [4-point scale from 'none' to 'severe'; assessed weekly], and Patient Global Impression of Change [7-point scale from 'very much better' to 'very much worse'; assessed weekly for night-time and daytime symptoms separately]). A supplemental distribution-based analysis was also conducted to support the anchor-based analysis. RESULTS: The analysis included 930 subjects aged 18-88 years. Spearman correlation coefficients for the relationships between score changes/ratings for anchors and the IDSIQ (0.36-0.44 at month 1, 0.45-0.57 at month 3) were all above the prespecified threshold of 0.30. Mean IDSIQ score changes at months 1 and 3 based on the different anchors supported meaningful within-patient change estimates starting at 17 points for the IDSIQ total score, 9 points for the Alert/Cognition domain, and 4 points for the Mood and Sleepiness domains. CONCLUSION: This analysis demonstrates the meaningful within-patient change for the IDSIQ total score and domain scores, that the instrument is sensitive to changes in the patient experience of insomnia, and that it can be used in clinical trials to evaluate changes in daytime functioning. CLINICAL TRIALS REGISTRATION: NCT03545191 (4 June 2018).

The Fibrodysplasia Ossificans Progressiva Physical Function Questionnaire (FOP-PFQ): A patient-reported, disease-specific measure.

OBJECTIVES: To assess the reliability and validity of age-specific versions of the Fibrodysplasia Ossificans Progressiva Physical Function Questionnaire (FOP-PFQ), developed to measure the impact of FOP on physical function and activities of daily living. METHODS: FOP-PFQ development included a literature review, two iterative phases of qualitative work involving individuals with FOP, and clinical expert review. The analysis used pooled FOP-PFQ data from an FOP natural history study (NCT02322255), a patient registry (NCT02745158), and phase II trials (NCT02190747; NCT02279095; NCT02979769). Item-level and factor analysis informed item retention and determined factor structure. Reliability was evaluated using Cronbach's alpha and intraclass correlation coefficients. Convergent validity was assessed by comparing scores with age, the Cumulative Analogue Joint Involvement Scale (CAJIS), the Patient-Reported Outcomes Measurement Information System Global Health Scale (PROMIS), and heterotopic ossification (HO) volume. Known-groups validity assessment used age, CAJIS, and HO volume. RESULTS: Factor analysis confirmed a two-factor solution: Mobility and Upper Extremity. Results reflected high internal consistency and were supportive of test-retest reliability; correlation coefficients >0.90 demonstrated FOP-PFQ scores were stable over a one- to three-week period. The majority of scores were moderately (r = 0.30-0.50) to highly (r ≥ 0.50) correlated with CAJIS and HO volume, supporting convergent validity. With the exception of some age-based and functional groups, FOP-PFQ scores were significantly worse in groups with more severe disease, demonstrating known-groups validity. CONCLUSION: The FOP-PFQ was demonstrated to be a reliable, valid measure that may be responsive to change in individuals with FOP, although some results were inconclusive for pediatric versions.

The International Burden of Migraine Study (IBMS): study design, methodology, and baseline cohort characteristics.

OBJECTIVE: To describe a survey methodology to evaluate headache characteristics and burden and to present baseline characteristics for the international cohort of survey participants. METHODS: A targeted, web-based methodology was used to recruit and survey subjects with migraine in 10 countries. Based on reported symptoms, subjects meeting ICHD-2 criteria for migraine were included; eligible subjects were classified as chronic (≥ 15 headache days per month) or episodic (< 15 headache days per month). Outcomes included sociodemographic and clinical characteristics, resource utilization, disability, health-related quality of life, anxiety, depression and productivity. RESULTS: Of 23,312 survey respondents, 11,897 were eligible and 9715 (81.7%) completed the survey; subjects were 81.5% female; 5.7% (n = 555) had chronic migraine. CONCLUSIONS: This is the first large international cohort of persons with chronic and episodic migraine studied using a web-based approach, a methodology well suited to the study of the burden of migraines.

Predicting EuroQol (EQ-5D) scores from the patient-reported outcomes measurement information system (PROMIS) global items and domain item banks in a United States sample.

BACKGROUND: Preference-based health index scores provide a single summary score assessing overall health-related quality of life and are useful as an outcome measure in clinical studies, for estimating quality-adjusted life years for economic evaluations, and for monitoring the health of populations. We predicted EuroQoL (EQ-5D) index scores from patient-reported outcomes measurement information system (PROMIS) global items and domain item banks. METHODS: This was a secondary analysis of health outcome data collected in an internet survey as part of the PROMIS Wave 1 field testing. For this study, we included the 10 global items and the physical function, fatigue, pain impact, anxiety, and depression item banks. Linear regression analyses were used to predict EQ-5D index scores based on the global items and selected domain banks. RESULTS: The regression models using eight of the PROMIS global items (quality of life, physical activities, mental health, emotional problems, social activities, pain, and fatigue and either general health or physical health items) explained 65% of the variance in the EQ-5D. When the PROMIS domain scores were included in a regression model, 57% of the variance was explained in EQ-5D scores. Comparisons of predicted to actual EQ-5D scores by age and gender groups showed that they were similar. CONCLUSIONS: EQ-5D preference scores can be predicted accurately from either the PROMIS global items or selected domain banks. Application of the derived regression model allows the estimation of health preference scores from the PROMIS health measures for use in economic evaluations.

Flushing ASsessment Tool (FAST): psychometric properties of a new measure assessing flushing symptoms and clinical impact of niacin therapy.

BACKGROUND AND OBJECTIVE: A common adverse effect of niacin therapy is flushing, manifested by cutaneous warmth, redness, itching and/or tingling. The Flushing ASsessment Tool (FAST) was developed to assess flushing symptoms and their impact on patients receiving niacin therapy. This study evaluated the reliability, validity and responsiveness of the FAST. The minimal important difference (MID) of the FAST was also examined. METHODS: This was a prospective, randomized, double-blind, placebo-controlled, parallel-group 8-week study conducted to evaluate the psychometric characteristics of the FAST. The instrument is administered daily using an electronic patient diary. The study was conducted at 41 clinical sites in the US. 276 patients with dyslipidaemia were randomized to treatment and were at least 18 years of age, with fasting laboratory values of low-density lipoprotein cholesterol (LDL-C) <250 mg/dL and one of the following: high-density lipoprotein cholesterol (HDL-C) <40 mg/dL for males or <50 mg/dL for females; or triglycerides (TG) > or = 150 and < or = 400 mg/dL; or LDL-C > or = 70 mg/dL for patients with a history of coronary heart disease (CHD) or CHD risk equivalents, or > or = 100 mg/dL for subjects with two risk factors, or > or = 160 mg/dL for subjects with 0-1 risk factors. Patients were randomized (1 : 1 : 1) to receive niacin extended-release (NER) 500 mg/day in week 1, 1000 mg/day in week 2 and 2000 mg/day in weeks 3-6/aspirin (acetylsalicylic acid [ASA]), NER/ASA placebo, or NER placebo/ASA placebo. RESULTS: FAST test-retest reliability in stable patients during the first 2 weeks was demonstrated for overall flushing severity using patient and physician overall treatment effect (OTE) ratings (intraclass correlation coefficients of >0.7 for mean overall and individual flushing severity scores). Over the 6-week treatment period, FAST scores demonstrated significant correlations with individual symptoms, impact on daily activities and sleep, and dissatisfaction related to flushing (p < 0.01). Changes in FAST scores were associated with treatment satisfaction (p < 0.01) and patient- and physician-rated OTE (p < 0.01). Using patient-rated OTE, the mean maximum flushing severity scores improved 1.85 points in responders and only 0.18 points in non-responders (p < 0.001); responders were defined by improved patient- or physician-rated OTE. Among patients with flushing, mean maximum overall flushing scores differed between patients who subsequently discontinued due to flushing (7.9 points) and those who did not discontinue (4.7 points; p < 0.001). The probable range in this study for a detectable change in flushing symptoms (MID) was 0.29-0.38 points for mean flushing severity and 0.66-0.86 points for maximum flushing severity. CONCLUSION: The FAST exhibited test-retest reliability, good evidence of construct validity, and, overall, flushing severity was responsive to change over time. The FAST is a reliable and valid instrument for assessing the impact of niacin-induced flushing in patients with dyslipidaemia.

Impact of Smoking and Alcohol Use on Facial Aging in Women: Results of a Large Multinational, Multiracial, Cross-sectional Survey.

Objective: Data on associations between facial aging and smoking or alcohol consumption are generally derived from small studies, and therefore, vary. The aim of this large multinational study was to determine more accurately which clinical signs of skin- and volume-related facial aging are associated with tobacco and alcohol use in women. Design: This was a subanalysis of a global, cross-sectional, Internet-based survey of self-reported facial aging. Participants: Women aged 18 to 75 years old (n=3,267) from the United States, Australia, Canada, and the United Kingdom who described themselves as white, Asian, black, or Hispanic were included. Measurements: Using a mirror, participants determined their own aging severity on photonumeric rating scales for 11 facial characteristics. Linear regressions were used to assess associations between each feature's severity and smoking status (never vs. current and former smoker); smoking pack years (0 versus 1-10, 11-20, and >20 years); alcohol use (none vs. moderate and heavy); and alcoholic beverage type, after controlling for body mass index, country, age, and race. Results: Smoking was associated with an increased severity of forehead, crow's feet, and glabellar lines; under-eye puffiness; tear-trough hollowing; nasolabial folds; oral commissures; perioral lines; and reduced lip fullness (p≤0.025) but not midface volume loss or visible blood vessels. Heavy alcohol use (≥8 drinks/week) was associated with increased upper facial lines, under-eye puffiness, oral commissures, midface volume loss, and blood vessels (p≤0.042). Conclusion: Smoking and alcohol consumption significantly but differentially impact skin and volume-related facial aging.

Converting EORTC QLQ-C30 scores to utility scores in the brigatinib ALTA study.

Aims: Health utilities summarize a patient's overall health status. This study estimated utilities based on the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (QLQ-C30), a widely used measure of health-related quality-of-life (HRQoL) in oncology, using published mapping algorithms. Materials and methods: Data were from the Anaplastic Lymphoma Kinase (ALK) in Lung Cancer Trial of brigatinib (ALTA; NCT02094573), an open-label, international, phase 2 study. ALTA evaluated the efficacy and safety of two randomized dosing regimens of brigatinib in patients with locally advanced or metastatic ALK + non-small cell lung cancer (NSCLC) that had progressed on prior therapy with crizotinib. QLQ-C30 scores were mapped to European Quality-of-Life-5 Dimensions (EQ-5D) utility scores using two published algorithms (Khan et al. for EQ-5D-5L; Longworth et al. for EQ-5D-3L). The impact of brigatinib treatment on health utilities over time was assessed. Results: The analysis included 208 subjects. Mean baseline utility scores for both algorithms ranged between 0.60 - 0.71 and increased to 0.78 by cycle 5. Utility improvements were sustained during most of the treatment, before disease progression. Minor variations were observed between utility scores; Khan et al. estimates were approximately 0.01 or 0.02 points lower than Longworth et al. estimates. Limitations: Algorithms considered were limited to those available in the published literature at the time of the study. This utility analysis was exploratory, and the ALTA trial did not include an internal control group (i.e. standard of care) and was not powered to detect differences in QoL/utility outcomes between treatment arms. Conclusions: Converting QLQ-C30 scores into utilities in trials using established mapping algorithms can improve evaluation of medicines from the patient perspective. Both algorithms suggested that brigatinib improved health utility in crizotinib-refractory ALK + NSCLC patients, and improvements were maintained during most of the treatment.

Development and Psychometric Evaluation of the Hypoglycemia Perspectives Questionnaire in Patients with Type 2 Diabetes Mellitus.

AIMS: The aim of this study was to evaluate the factor structure and psychometric characteristics of the Hypoglycemia Perspectives Questionnaire (HPQ) assessing experience and perceptions of hypoglycemia in patients with type 2 diabetes mellitus (T2DM). METHODS: HPQ was administered to adults with T2DM in a clinical sample from Cyprus (HYPO-Cyprus, n = 500) and a community sample in the United States (US, n = 1257) from the 2011 US National Health and Wellness Survey. Demographic and clinical data were collected. Analysis of HPQ data from two convenience samples examined item performance, factor structure, and HPQ measurement properties (reliability, convergent validity, known-groups validity). RESULTS: Analyses supported three HPQ domains: symptom concern (six items), compensatory behavior (five items), and worry (five items). Internal consistency was high for all three domains (all ≥0.75), supporting reliability. Convergent validity was supported by moderate Spearman correlations between HPQ domain scores and the Audit of Diabetes-Dependent Quality of Life (ADDQoL-19) total score. Patients with recent hypoglycemia events had significantly higher HPQ scores, supporting known-group validity. CONCLUSIONS: HPQ may be a valid and reliable measure capturing the experience and impact of hypoglycemia and useful in clinical trials and community-based settings.

Factors associated with potentially inappropriate drug utilization in a sample of rural community-dwelling older adults.

BACKGROUND: Many medications present special risks when used by older adults (ie, those aged > or = 65 years) and are considered potentially inappropriate for this population. The Beers criteria are often used to identify such medications. Past research has documented that use of Beers drugs is common among older adults. OBJECTIVE: The aim of this work was to examine factors associated with potentially inappropriate drug use among rural community-dwelling older adults using a conceptual framework adapted from the Andersen-Newman behavioral model of health service use. METHODS: This was a population-based, cross-sectional survey. Data were collected via face-to-face home interviews between 2002 and 2004. Rural community-dwelling older adults residing in a single county in North Carolina were eligible. Potentially inappropriate drug use was operationalized using the Beers criteria. Data concerning predisposing (ie, age, sex, race, education, and marital status), enabling (ie, social support and insurance status), need (ie, disability and history of major depression, hypertension, osteoarthritis, back problems, or other comorbidities), and utilization factors (ie, number of medications used) were collected. RESULTS: Data were gathered from 892 people, with information on medication use available for 800. Two hundred thirteen of these 800 participants (26.6%) used > or = 1 Beers drug. Compared with individuals who used no Beers drugs, those who used > or = 1 Beers drug reported lower levels of social support (odds ratio [OR], 0.94; 95% CI, 0.90-0.99) and higher levels of disability (OR, 1.48; 95% CI, 1.11-1.97), used more medications (OR, 1.07; 95% CI, 1.01-1.13), and were more likely to have a history of major depression (OR, 1.67; 95% CI, 1.05-2.66), hypertension (OR, 1.58; 95% CI, 1.07-2.33), osteoarthritis (OR, 1.58; 95% CI, 1.09-2.29), and back problems (OR, 1.72; 95% CI, 1.19-2.47). CONCLUSION: As suggested by the Andersen-Newman model, the risk of potentially inappropriate drug use is highest among those with the greatest medication needs, as evidenced by poorer health status in this sample of rural community-dwelling older patients.

Acne treatment patterns, expectations, and satisfaction among adult females of different races/ethnicities.

BACKGROUND: Limited data are available on acne treatment patterns, expectations, and satisfaction in the adult female subpopulation, particularly among different racial and ethnic groups. OBJECTIVE: Describe acne treatment patterns and expectations in adult females of different racial/ethnic groups and analyze and explore their potential effects on medication compliance and treatment satisfaction. METHODS: A cross-sectional, Web-based survey was administered to US females (25-45 years) with facial acne (≥25 visible lesions). Data collected included sociodemographics, self-reported clinical characteristics, acne treatment use, and treatment expectations and satisfaction. RESULTS: Three hundred twelve subjects completed the survey (mean age, 35.3±5.9 years), comprising black (30.8%), Hispanic (17.6%), Asian/other (17.3%), and white (34.3%). More than half of the subjects in each racial group recently used an acne treatment or procedure (black, 63.5%; Hispanic, 54.5%; Asian/other, 66.7%; white, 66.4%). Treatment use was predominantly over-the-counter (OTC) (47.4%) versus prescription medications (16.6%). OTC use was highest in white subjects (black, 42.7%; Hispanic, 34.5%; Asian/other, 44.4%; white, 59.8%; P<0.05). The most frequently used OTC treatments in all racial/ethnic groups were salicylic acid (SA) (34.3%) and benzoyl peroxide (BP) (32.1%). Overall, compliance with acne medications was highest in white versus black (57.0±32.4 vs 42.7±33.5 days, P>0.05), Hispanic (57.0±32.4 vs 43.2±32.9 days, P>0.05), and Asian/other (57.0±32.4 vs 46.9±37.2 days, P>0.05) subjects. Most subjects expected OTC (73.7%) and prescription (74.7%) treatments to work quickly. Fewer than half of the subjects were satisfied with OTC treatment (BP, 47.0%; SA, 43.0%), often due to skin dryness (BP, 26.3%; SA, 44.3%) and flakiness (BP, 12.3%; SA, 31.1%). No statistically significant differences were observed among racial/ethnic groups in their level of satisfaction with OTC or prescription acne treatments. CONCLUSION: Racial/ethnic differences were observed in acne treatment patterns in adult females, while treatment expectations were similar. Results indicate that treatment patterns and expectations may impact treatment satisfaction and medication compliance.

Acne-Related Quality of Life Among Female Adults of Different Races/Ethnicities.

BACKGROUND: Acne impairs quality of life, but its effect on different races/ethnicities is unclear. This study evaluated racial/ethnic differences in acne-related quality of life and psychological symptoms among female adults. METHODS: A Web-based survey was conducted with U.S. female adults (25-45 years old) with facial acne (≥25 visible lesions). Outcomes included sociodemographics, clinical characteristics, acne-related quality of life (Acne-Specific Quality of Life Questionnaire), psychological symptoms (Patient Health Questionnaire), and work/school productivity. Racial/ethnic differences were evaluated using descriptive statistics and analysis of variance/chi-square analyses. RESULTS: Three-hundred twelve subjects (Black = 30.8%, Hispanic = 17.6%, Asian/other = 17.3%, White = 34.3%) completed the survey (mean age = 35.3 ± 5.9 years). Acne negatively impacted quality of life for all subjects. Black subjects reported significantly less negative impact on self-perception versus Asian/other (Black = 12.6 ± 9.9, Asian/other = 8.4 ± 8.6; p = .05). Social functioning was less negatively impacted in White and Black subjects versus Asian/other (White = 12.7 ± 7.5, Asian/other = 8.4 ± 7.8, p < .05; Black = 12.1 ± 9.2, Asian/other = 8.4 ± 7.8, p = .06). Over one third (total sample = 40.7%, Black = 31.3%, Hispanic = 36.4%, Asian/other = 50.0%, White = 46.7%) reported moderate/severe anxiety/depression symptoms. Acne also impacted ability to concentrate on work/school. CONCLUSION: Racial/ethnic differences were observed in acne-related quality of life and psychological symptoms in female adults; acne negatively impacted self-perceptions and social/emotional functioning.

Evaluation of patient preference and willingness to pay for attributes of maintenance medication for chronic obstructive pulmonary disease (COPD).

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. COPD is characterized by poor treatment adherence, and patient medication preferences may contribute to adherence. METHODS: A discrete choice experiment with an internet panel drawn from the USA was used to evaluate preference and willingness to pay (WTP) of COPD patients for long-acting maintenance medications. Key attributes derived from earlier qualitative research (brief literature review and focus groups) with COPD patients on maintenance therapy included symptom relief, speed of feeling medication start to work, inhaler ease of use, rescue medication use, side effects, and monthly out-of-pocket co-pay. Patients were presented with hypothetical medications with different profiles and asked which they preferred. Utilities and marginal WTP in monthly co-pay dollars were estimated for all patients and by severity. RESULTS: Utilities for 515 participants were in the expected direction and highest for the most favorable attribute levels. Each attribute evaluated was important, and participants were willing to pay a premium to obtain each benefit. On average, WTP was as high as $US64 for complete symptom relief, $US59 for no side effects, $US32 to rarely use rescue medication, $US16 for a quick and easy to use inhaler, and $US13 for feeling medication work quickly (within 5 min; average WTP $US18/month for patients with severe/very severe COPD). CONCLUSION: As expected, efficacy and safety were most valued by patients; however, this study showed that other COPD medication attributes, such as rescue medication, ease of use, and feeling medication work quickly, are also important in patient preferences.

Racial differences in clinical characteristics, perceptions and behaviors, and psychosocial impact of adult female acne.

OBJECTIVE: Limited data are available on racial differences in clinical characteristics and burden in adult female acne. The objective was to describe racial differences in clinical characteristics, psychosocial impact, perceptions, behaviors, and treatment satisfaction in facial adult female acne. DESIGN: Cross-sectional, web-based survey. SETTING: Diverse sample of United States women. PARTICIPANTS: Women between the ages of 25 and 45 years with facial acne (≥25 visible lesions). MEASUREMENTS: Outcomes included sociodemographic characteristics, psychosocial impacts, perceptions, behaviors, and treatment satisfaction. Racial differences were evaluated using descriptive statistics and t-test/chi-square analyses. RESULTS: 208 females participated (mean age 35±6 years); 51.4 percent were White/Caucasian and 48.6 percent were non-White/Caucasian women [Black/African American (n=51); Hispanic/Latina (n=23); Asian (n=16); Other (n=ll)]. Age of acne onset (mean 14.8±5 vs. 17.0±8 years, p<0.05) and acne concern occurred earlier (16.6±7 vs. 19.3±9 years, p<0.05) in White/Caucasian than non-White/Caucasian subjects. Facial acne primarily presented on chin (28.0%) and cheeks (30.8%) for White/Caucasian women versus cheeks (58.4%) for non-White/Caucasian women. Non-White/Caucasian women experienced more postinflammatory hyperpigmentation than White/Caucasian women (p<0.0001). Facial acne negatively affected quality of life (QoL) in both groups, and most participants (>70%) reported some depression/anxiety symptoms. More White/Caucasian than non-White/Caucasian women were troubled by facial acne (88.8% vs. 76.2%, p<0.05). Lesion clearance was most important to White/Caucasian women (57.9 vs. non-White/Caucasian 31.7%, p<0.001); non-White/Caucasian females focused on postinflammatory hyperpigmentation clearance (41.6% vs. Caucasian 8.4%, p<0.0001). CONCLUSION: RESULTS highlight racial differences in participant-reported clinical characteristics, attitudes, behaviors, and treatment satisfaction. These findings may inform clinicians about racial differences in facial adult female acne and guide treatment recommendations toward improving care.
