Profile and quality of life of the adult population in good health according to the level of vitality: European NHWS cross sectional analysis.

BACKGROUND: The World Health Organization's definition of health highlights the importance of mental and physical wellbeing and not only disease state. However, lack of awareness on the burden of impaired vitality and its impact on the quality of life of the general healthy population prevents healthcare providers from delivering appropriate solutions and advice. This study aims to better characterize this population in Europe and identify the profile and the health reported outcomes associated with impaired vitality. METHODS: This retrospective observational study included National Health and Wellness Survey (NHWS) data collected in healthy participants aged 18-65 years from five European Union countries in 2018. Socio-demographic and lifestyle characteristics, comorbidities, attitudes towards healthcare systems, Patient Activation Measure, health-related quality of life outcomes (EQ-5D), and work productivity and activity impairment were analysed according to SF-12 vitality score subgroups (≥ 60, 50- < 60, 40- < 50, < 40). RESULTS: A total of 24,295 participants were enrolled in the main analysis. Being a female, younger, having a lower income and being obese or having sleep and mental disorders was associated with an increased risk of impaired vitality. This was associated with a higher consumption of healthcare resources along with having a weak patient-physician relationship. Participants who were disengaged in the self-management of their health were 2.6 times more likely to have a low level of vitality. For participants in the lowest vitality group, odds of mobility problems increased by 3.4, impairment of usual activity by 5.8, increased of pain and discomfort by 5.6 and depression and anxiety by 10.3, compared with participants in the highest vitality group. Also, odds of presenteeism increased by 3.7, overall work impairment by 3.4 and daily activity losses by 7.1. CONCLUSION: Evidence-based trends facilitate the identification of a healthy population with impaired vitality in real-world practice. This study highlights the actual burden of low vitality on daily life activities, particularly on mental health and reduced work productivity. Additionally, our results underline the importance of self-engagement in the management of vitality impairment and highlights the need to implement strategies to address this public health concern in the affected population (HCP-patient communication, supplements, meditation).

Social Media Listening and Digital Profiling Study of People With Headache and Migraine: Retrospective Infodemiology Study.

BACKGROUND: There is an unmet need for a better understanding and management of headache, particularly migraine, beyond specialist centers, which may be facilitated using digital technology. OBJECTIVE: The objective of this study was to identify where, when, and how people with headache and migraine describe their symptoms and the nonpharmaceutical and medicinal treatments used as indicated on social media. METHODS: Social media sources, including Twitter, web-based forums, blogs, YouTube, and review sites, were searched using a predefined search string related to headache and migraine. The real-time data from social media posts were collected retrospectively for a 1-year period from January 1, 2018, to December 31, 2018 (Japan), or a 2-year period from January 1, 2017, to December 31, 2018 (Germany and France). The data were analyzed after collection, using content analysis and audience profiling. RESULTS: A total of 3,509,828 social media posts related to headache and migraine were obtained from Japan in 1 year and 146,257 and 306,787 posts from Germany and France, respectively, in 2 years. Among social media sites, Twitter was the most used platform across these countries. Japanese sufferers used specific terminology, such as "tension headaches" or "cluster headaches" (36%), whereas French sufferers even mentioned specific migraine types, such as ocular (7%) and aura (2%). The most detailed posts on headache or migraine were from Germany. The French sufferers explicitly mentioned "headache or migraine attacks" in the "evening (41%) or morning (38%)," whereas Japanese mentioned "morning (48%) or night (27%)" and German sufferers mentioned "evening (22%) or night (41%)." The use of "generic terms" such as medicine, tablet, and pill were prevalent. The most discussed drugs were ibuprofen and naproxen combination (43%) in Japan; ibuprofen (29%) in Germany; and acetylsalicylic acid, paracetamol, and caffeine combination (75%) in France. The top 3 nonpharmaceutical treatments are hydration, caffeinated beverages, and relaxation methods. Of the sufferers, 44% were between 18 and 24 years of age. CONCLUSIONS: In this digital era, social media listening studies present an opportunity to provide unguided, self-reported, sufferers' perceptions in the real world. The generation of social media evidence requires appropriate methodology to translate data into scientific information and relevant medical insights. This social media listening study showed country-specific differences in headache and migraine symptoms experienced and in the times of the day and treatments used. Furthermore, this study highlighted the prevalence of social media usage by younger sufferers compared to that by older sufferers.

A Retrospective Real-World Observational Study Assessing the Evolution of Bisacodyl Prescriptions in Patients with Constipation During Long-Term Treatment.

BACKGROUND: Potential habituation could be a safety concern associated with the long-term use of bisacodyl in patients with constipation. OBJECTIVE: In this study, we evaluated whether patients with constipation who require long-term treatment with bisacodyl will remain on a stable dose when treated for ≥ 28 days. METHODS: In this retrospective, population-based, observational cohort study, electronic medical record data of adult patients with constipation between January 1, 2011, and December 31, 2019, were collected from The Health Improvement Network French database. Total bisacodyl exposure during the long-term (≥ 28 days) and follow-up (12 months) periods was evaluated. The primary endpoint was the dose change status of bisacodyl during the follow-up period from the initial dose in the long-term cohort. RESULTS: Out of 5725 bisacodyl users in the database, 218 patients qualified to be part of the long-term cohort. A total of 166 (76.1%), 37 (17%), and 15 (6.9%) patients were initiated on bisacodyl at 5, 7.5, and 10 mg, respectively. During the follow-up, most (94%) of the patients remained on the same dose as initially prescribed for the first year. In contrast, only seven (3.2%) patients had their dose increased (from the initial prescribed dose of 5 mg), and the remaining six (2.8%) patients decreased their dose (four patients from the 7.5 mg group and two from the 10 mg group). CONCLUSION: Bisacodyl can be prescribed at a stable dose for > 28 days as most patients remained on their initial prescribed dose during the follow-up period. No signs of habituation were observed in this real-world study.

Impact of exacerbations on lung function, resource utilization, and productivity: results from an observational, prospective study in adults with uncontrolled asthma.

Background: Exacerbations have a major impact on the well-being of patients with uncontrolled asthma. This study evaluated lung function, healthcare resource utilization (HCRU), and productivity loss following asthma exacerbations.Methods: This single-center, observational, prospective cohort study recruited US patients presenting clinically with an acute asthma exacerbation; a reference group without exacerbations was included for comparison. Lung function (forced expiratory volume in 1 second [FEV1]) was collected at baseline, daily during Month 1, and monthly for Months 2-5, and reported as FEV1 percent predicted (FEV1pp). HCRU (outpatient visits to a healthcare practitioner, emergency room [ER] visits, and hospitalizations for asthma), oral corticosteroid (OCS) use, and asthma-related work/school absence were collected monthly for 6 months.Results: Overall, 150 patients were recruited (exacerbation: n=102; reference: n=48; mean [SD] age: 42.7 [15.2] and 49.6 [12.4] years; female: 73% and 71%). In both groups, similar trends were observed in FEV1, with significant improvement from baseline to Week 1 (p<0.05), followed by a continuous decline. FEV1p was 7.7% lower at baseline and 8.6% lower at Month 5 in the exacerbation group versus the reference group. The exacerbation group had significantly higher rates of OCS prescription during follow-up versus reference group (p=0.04). Over half (52.9%) of patients in the exacerbation group had a recurrent exacerbation during follow-up, increased HCRU (outpatient visits, ER visits, and hospitalizations), and impaired productivity.Conclusion: Although patients with exacerbations had rapid recovery of lung function, this was not maintained and declined faster than in patients without exacerbations. Additionally, patients experienced increased HCRU after exacerbations.

Real world evidence of the use of metamizole (dipyrone) by the Brazilian population. A retrospective cohort with over 380,000 patients.

OBJECTIVE: To determine under which health conditions metamizole (dipyrone) is used as a single drug or as fixed-dose combination. METHODS: Two retrospective cohorts of Brazilian patients treated with metamizole between January 2015 and December 2017 were analyzed: a metamizole-based cohort (Cohort 1) and a symptoms-based cohort (Cohort 2). Anonymized patient data was obtained from Amil Clinical Data Warehouse. The number of patients with symptoms was described by age and sex. RESULTS: The sample size of the two cohorts consisted of 384,668 patients. In patients using metamizole (Cohort 1), the most common reason for medication was the treatment of some form of pain (81%), followed by fever (19%). Headache was the most common (19%) specified pain class, followed by sore throat (8%), muscular pain (6%), and abdominal pain (5%). In adult patients (n=276,279; 71.8%), metamizole was used as a monotherapy or associated with another drug, for any sort of pain, in over 88% of the patients. General pain was the main reason for metamizole use in children (61%). CONCLUSION: Real world evidence to evaluate Brazilian patients' therapeutic options is unusual and yet to be more explored using digital tools enabling better data registration. The present study confirmed that metamizole is widely used as a non-anti-inflammatory drug, and also showed the management of pain and fever as the most frequent indications in all age groups studied.Registry in Clinical Trials Database: REBEC Database: 10507.

The Use of Real-World Data to Evaluate the Association Between Atopic Dermatitis and Cardiovascular Disease: A Retrospective Claims Analysis.

INTRODUCTION: Atopic dermatitis (AD) is a systemic inflammatory condition that may increase the risk of cardiovascular disease (CVD); however, ongoing debate exists surrounding its direct association. We aimed to elucidate whether AD contributes to a higher incidence of CVD and major adverse cardiovascular events (MACE) in adult patients with AD, independent of metabolic disorders. METHODS: We retrospectively analyzed a large US-based population of patients with AD (≥ 18 years of age). Logistic regression estimated the risk of CVD and MACE in adult patients with AD, independent of metabolic disorders (including diabetes, hypertension, and obesity). RESULTS: The odds ratio (OR; 95% confidence interval [CI]) for patients without metabolic disorders was 1.25 (1.13, 1.39) for CVD and 1.22 (1.01, 1.47) for MACE. The OR (95% CI) for AD patients with metabolic disorders was 1.09 (1.07, 1.12) for CVD and 1.14 (1.09, 1.18) for MACE. This trend was even more pronounced after long-term follow-up (≥ 3 years). Lifestyle and health behavioral factors of the subjects were not available in the dataset. The lack of control for these factors could potentially confound our results. CONCLUSIONS: Atopic dermatitis may contribute to the risk of developing CVD and MACE in adults, independent of metabolic disorders.

Incidence of respiratory syncytial virus related health care utilization in the United States.

BACKGROUND: Respiratory Syncytial Virus (RSV) is one of the most frequent causes of acute respiratory infection worldwide. Understanding age-specific health care utilization is necessary to guide effective prevention strategies. This retrospective database analysis assessed the incidence rates of RSV-related health care utilization in the USA over a 7-year period. METHODS: Episodes of RSV were identified in the Truven Health MarketScan® Commercial Claims and Encounters database between 2008 and 2014 using ICD-9-CM codes for pneumonia, bronchiolitis and RSV (480-486, 487.0, 466.1, 491.2, 079.6). Annual RSV-related health care utilization was calculated for the total population, by age group (<1, 1, 2-4, 5-17, 18-49, 50-64, 65-74, 75-84 and ≥85 years) and the proportion of cases for each setting (hospitalization, outpatient, or emergency department [ED] / urgent care [UC]). RESULTS: Over the 7-year study period, the mean rate of all RSV-associated health care utilization was 2.4 per 1000 person-years, with mean rates ranging from 2.0 to 2.6). The highest rate was seen in infants aged <1 year (mean 79.0 per 1000 over the 7-year period), which decreased with increasing age in the range 2-49 years before increasing with age in older adults (mean rate 8.1 per 1000 over the 7-year period in those ≥85 years). Of all RSV cases, 82% were reported in an outpatient setting, 11% in the ED/UC and 7% were hospitalized. CONCLUSIONS: The annual RSV-related healthcare utilization rates were substantial, especially in infants and young children. These results underscore the need to accelerate the development of RSV prevention strategies to reduce the healthcare burden of RSV.

Health Assessment Questionnaire-Disability Index (HAQ-DI) use in modelling disease progression in diffuse cutaneous systemic sclerosis: an analysis from the EUSTAR database.

BACKGROUND: Patients with diffuse cutaneous systemic sclerosis (dcSSc) have a poor prognosis. The importance of monitoring subjective measures of functioning and disability, such as the Health Assessment Questionnaire-Disability Index (HAQ-DI), is important as dcSSc is rated by patients as worse than diabetes or hemodialysis for quality of life impairment. This European Scleroderma Trials and Research (EUSTAR) database analysis was undertaken to examine the importance of impaired functionality in dcSSc prognosis. The primary objectives were to identify predictors of death and HAQ-DI score progression over 1 year. HAQ-DI score, major advanced organ involvement, and death rate were also used to develop a comprehensive model to predict lifetime dcSSc progression. METHODS: This was an observational, longitudinal study in patients with dcSSc registered in EUSTAR. Death and HAQ-DI scores were, respectively, analyzed by Cox regression and linear regression analyses in relation to baseline covariates. A microsimulation Markov model was developed to estimate/predict natural progression of dcSSc over a patient's lifetime. RESULTS: The analysis included dcSSc patients with (N = 690) and without (N = 4132) HAQ-DI score assessments from the EUSTAR database. Baseline HAQ-DI score, corticosteroid treatment, and major advanced organ involvement were predictive of death on multivariable analysis; a 1-point increase in baseline HAQ-DI score multiplied the risk of death by 2.7 (p <  0.001) and multiple advanced major organ involvement multiplied the risk of death by 2.8 (p <  0.05). Multivariable analysis showed that baseline modified Rodnan Skin Score (mRSS) and baseline HAQ-DI score were associated with HAQ-DI score progression at 1 year (p <  0.05), but there was no association between baseline organ involvement and HAQ-DI score progression at 1 year. HAQ-DI score, major advanced organ involvement, and death were successfully used to model long-term disease progression in dcSSc. CONCLUSIONS: HAQ-DI score and major advanced organ involvement were comparable predictors of mortality risk in dcSSc. Baseline mRSS and baseline HAQ-DI score were predictive of HAQ-DI score progression at 1 year, indicating a correlation between these endpoints in monitoring disease progression. It is hoped that this EUSTAR analysis may change physician perception about the importance of the HAQ-DI score in dcSSc.

Treatment patterns in UK adult patients with atopic dermatitis treated with systemic immunosuppressants: data from The Health Improvement Network (THIN).

Background: There is limited understanding on patterns of systemic treatment in adults with moderate-to-severe atopic dermatitis (AD) in the UK.Objective: To characterize treatment patterns in adult AD patients prescribed immunosuppressants (IMMs) in the primary care setting.Results: Six hundred and fifty-six patients with AD (6.6%) were prescribed IMM in the analysis (mean age 52.1 years; 59.1% female; age-adjusted Charlson comorbidity index 1.4). Most prevalent (>5%) conditions at baseline were depression (10.8%), contact dermatitis (10.7%), rheumatological disease (7.9%), skin/subcutaneous tissue disorders (6.4%), upper respiratory disease (5.8%), and psoriasis (5.2%). At baseline, up to 50% of patients were prescribed ≥1 IMM. During follow-up, 42.7% of patients were prescribed oral corticosteroids (OCSs), increasing in line with IMM exposure. The most commonly prescribed IMM was methotrexate (43.3%). Ciclosporin, the only approved IMM for AD, was prescribed to 16.9% of patients.Conclusions: The prevalence of comorbidities and high rate of IMM prescriptions demonstrate the impact of AD on quality of life. The frequency of OCS prescribing in AD patients treated with IMMs suggests a lack of disease control with existing therapies, and an unmet need for safe and effective targeted agents for long-term disease control.

Cost burden and resource utilization in patients with chronic rhinosinusitis and nasal polyps.

OBJECTIVES/HYPOTHESIS: Establish treatment patterns and economic burden in US patients with chronic rhinosinusitis with nasal polyposis (CRSwNP) versus without chronic rhinosinusitis (CRS). Determine comparative costs of subgroups with high clinical burden. STUDY DESIGN: Observational, retrospective, case-control study. METHODS: This study matched patients with CRSwNP to patients without CRS (1:1) using the Truven Health MarketScan US claims database. Categorical and continuous variables were compared using McNemar test and paired t test (normal distribution) or Wilcoxon signed rank tests (non-normal distribution). Within subgroups, χ2 and Wilcoxon or t tests were used (normal distribution). RESULTS: There were 10,841 patients with CRSwNP and 10,841 patients without CRS included. Mean age in the CRSwNP cohort was 45.8 years; 56.2% were male. During follow-up, patients with CRSwNP had an increased diagnosis of asthma versus patients without CRS (20.8% vs. 8.1%, respectively; P < .001). Annual incremental costs were $11,507 higher for patients with CRSwNP versus those without CRS. Costs were higher in subgroups of patients with CRSwNP undergoing functional endoscopy sinus surgery (FESS), with a comorbid diagnosis of asthma, receiving oral corticosteroids, or macrolides versus the overall CRSwNP group. Patients with CRSwNP undergoing FESS had the highest costs of the four subgroups ($26,724, $22,456, $20,695, and $20,990, respectively). CONCLUSIONS: Annual incremental costs were higher among patients with CRSwNP versus without CRS. Patients with CRSwNP with high clinical burden had higher overall costs than CRSwNP patients without. LEVEL OF EVIDENCE: NA Laryngoscope, 129:1969-1975, 2019.

Trends in healthcare utilization and costs associated with pneumonia in the United States during 2008-2014.

BACKGROUND: Pneumonia is the leading cause of morbidity and mortality worldwide. Pneumococcal conjugate vaccines have reduced the burden of pneumonia, but data on the current burden of pneumonia and its impact on the healthcare system are needed to inform the development and use of new vaccines and other preventive measures. METHODS: We retrospectively analyzed the frequency of pneumonia in the US during 2008-2014 using data from the MarketScan® Commercial Claims and Encounters database. Frequencies of healthcare utilization related to the index pneumonia episode were calculated using the annual number of enrolled person-years (PY) as the denominator and the number of individuals with pneumonia as the numerator. Pneumonia-associated costs were calculated as mean payment per episode during the 2 years from 2013 to 2014. RESULTS: The overall annual healthcare utilization rate for pneumonia was 15.1 per 1000 PY and decreased slightly from 2008 to 2014 (from 15.4 to 13.5 per 1000 PY). Most pneumonia-related healthcare utilization was due to office/outpatient visits (10.3 per 1000 PY; 68.3%). Emergency department/urgent care visits (2.5 per 1000 PY; 16.9%) and hospitalizations (2.2 per 1000 PY; 14.8%) contributed less. Pneumonia-related healthcare utilization was highest in children < 5 years (rate per 1000 PY = 29.7 for < 1 year, 47.9 for 1 year, and 39.5 for 2-4 years) and adults > 65 years (45.0 per 1000 PY). The mean cost per pneumonia episode (95% confidence interval) was US$429.1 ($424.8-$433.4) for office/outpatient visits, $1126.9 ($1119.5-$1134.3) for emergency department/urgent care visits, and $10,962.5 ($10,822.8-$11,102.2) for hospitalization. CONCLUSIONS: The burden of pneumonia on the US healthcare system remains substantial. The results presented here can help guide new vaccination strategies and other preventive interventions for reducing the remaining burden of pneumonia.

Trends in healthcare utilization and costs associated with acute otitis media in the United States during 2008-2014.

BACKGROUND: Acute otitis media (AOM) is the most common cause of pediatric medical visits and antibiotic prescriptions worldwide, but its current impact on the US healthcare system is not clear. The aim of this study was to investigate changes in the incidence of AOM from 2008, just before 13-valent pneumococcal conjugate vaccine was introduced, to 2014 using US insurance records in the Truven MarketScan® database. The study also examined the costs associated with index AOM events during the two most recent years for which data were available (2013-2014). METHODS: AOM cases in the MarketScan database during 2008-2014 were identified using ICD9 diagnosis codes 381.xx and 382.xx. Incidence rates of healthcare utilization related to the index AOM episode were calculated using the annual number of enrolled person-years as the denominator and the number of individuals with AOM as the numerator. AOM-associated costs were calculated as the mean payment per episode during the 2 years from 2013 to 2014. RESULTS: The overall annual rate of AOM-related healthcare utilization was 60.5 per 1000 person-years and changed little from 2008 to 2014 (range, 58.4-62.6). Most of this was due to office/outpatient visits (55.7 [range, 52.0-58.8] per 1000 person-years). Emergency department/urgent care visits (4.7 [range 3.7-6.3] per 1000 person-years) and hospitalization (0.0 [range, 0.0-0.1] per 1000 person-years) contributed little. The rate of AOM-related healthcare utilization per 1000 person-years was highest in the youngest children and declined with age (474.3 for < 1 year, 503.9 for 1 year, 316.3 for 2-4 years, 94.9 for 5-17 years, 33.1 for 18-49 years, 28.6 for 50-64 years, 23.7 for 65-74 years, 20.2 for 75-84 years, and 16.1 for ≥85 years). The mean cost per AOM episode in 2013-2014 (95% confidence interval) was $199.0 (198.4-199.6) for office or outpatient visits, $329.6 (328.2-331.0) for emergency department/urgent care visits, and $1592.9 (1422.0-1763.8) for hospitalization. CONCLUSIONS: In the US, AOM-associated healthcare utilization and costs remain substantial. More effective preventive measures such as new vaccines are needed to reduce the burden of AOM.

Healthcare resource use and economic burden attributable to respiratory syncytial virus in the United States: a claims database analysis.

BACKGROUND: Despite several studies that have estimated the economic impact of Respiratory Syncytial Virus (RSV) in infants, limited data are available on healthcare resource use and costs attributable to RSV across age groups. The aim of this study was to quantify age-specific RSV-related healthcare resource use and costs on the US healthcare system. METHODS: This retrospective case-control study identified patients aged ≥1 year with an RSV event in the Truven Health Marketscan® Commercial Claims and Encounters and Medicare Supplemental and Coordination of Benefits databases between August 31, 2012 and August 1, 2013. RSV patients were matched 1:1 with non-RSV controls for age, gender, region, healthcare plan and index date (n = 11,432 in each group). Stratified analyses for healthcare resource use and costs were conducted by age groups. RSV-attributable resource use and costs were assessed based on the incremental differences between RSV cases and controls using multivariate analysis. RESULTS: RSV patients had a higher healthcare resource use (hospital stays, emergency room/urgent care visits, ambulatory visits and outpatient visits) than non-RSV matched controls for all age groups (all p < 0.0001), particularly in the elderly age groups with RSV (1.9 to 3 days length of stay, 0.4 to 0.5 more ER/UC visits, 0.7 to 2.7 more ambulatory visits, 12.1 to 18.6 more outpatient visits and 9.5 to 14.6 more prescriptions than elderly in the control groups). The incremental difference in adjusted mean annual costs between RSV and non-RSV controls was higher in elderly (≥65; $12,030 to $23,194) than in those aged < 65 years ($2251 to $5391). Among children, adjusted costs attributable to RSV were higher in children aged 5-17 years ($3192), than those 1-4 years ($2251 to $2521). CONCLUSIONS: Our findings showed a substantial annual RSV-attributable healthcare resource use and costs in the US across age groups, with the highest burden in those aged ≥65 years. These data can be used in cost-effectiveness analyses, and may be useful for policymakers to guide future RSV vaccination and other prevention programs.

The burden of atopic dermatitis in US adults: Health care resource utilization data from the 2013 National Health and Wellness Survey.

BACKGROUND: There is a lack of data on the burden of atopic dermatitis (AD) in adults relative to the general population. OBJECTIVE: To characterize the AD burden in adult patients relative to both matched non-AD controls and matched patients with psoriasis in terms of comorbidities, health care resource utilization (HCRU), and costs. METHODS: Adults (≥18 years) who self-reported a diagnosis of AD or psoriasis and adult non-AD controls were identified from the 2013 US National Health and Wellness Survey. Patients with AD were propensity score-matched with non-AD controls and patients with psoriasis on demographic variables. Patient-reported outcomes were analyzed between matched cohorts. RESULTS: Patients with AD had a significantly greater risk for atopic comorbidities, as well as significantly greater HCRU and total cost compared with non-AD controls. The burden of AD was generally comparable to that of psoriasis, although patients with AD reported increased use of emergency room visits compared with patients with psoriasis. LIMITATIONS: Patient-reported data are susceptible to recall bias and erroneous classification. CONCLUSIONS: Adult patients with AD reported a substantial disease burden, suggesting an unmet need for more effective AD treatment options.

Health Care Resource Utilization and Costs Among Adults with Atopic Dermatitis in the United States: A Claims-Based Analysis.

BACKGROUND: Data on health care resource utilization (HCRU) and costs for patients with atopic dermatitis (AD) are lacking. OBJECTIVE: The objective of this study was to determine HCRU and costs associated with AD in US adults. METHODS: This retrospective study identified patients with AD from the Truven Health Marketscan Commercial Claims and Encounters database during 2013 based on ≥2 claims with International Classification of Diseases, Ninth Revision code 691.8 (n = 10,533; first claim = index event); 1-year continuous enrollment before and after index was required. Patients were age- and gender-matched in a 1:3 ratio to controls without AD (n = 31,599). Patients with AD were further categorized into 2 groups, with treatment regimens as surrogates for increasing disease severity: claim for phototherapy or systemic immunomodulatory agents (more severe) or no claim for either (less severe). Incremental differences in resource use and costs were evaluated using multivariate analysis. RESULTS: AD was associated with higher utilization and costs across resource categories (all P < .0001); adjusted total incremental annual costs were $3,302. Resource utilization and costs were higher in the more severe group, with adjusted total incremental annual costs of $4,463. CONCLUSION: AD is associated with significant incremental health care utilization and costs, which are higher in patients with more severe disease.

Impact of atopic dermatitis on health-related quality of life and productivity in adults in the United States: An analysis using the National Health and Wellness Survey.

BACKGROUND: Given its public health impact, there is need for broad and representative data on the humanistic burden of atopic dermatitis (AD). OBJECTIVE: To establish the humanistic burden of AD in US adults. METHODS: Data were from the 2013 US National Health and Wellness Survey; AD self-reports were propensity-matched with non-AD controls and with psoriasis controls. Bivariate analyses were conducted on burden outcomes between the AD and control groups. RESULTS: Demographics and baseline characteristics were comparable between matched groups. Subjects with AD (n = 349) versus non-AD controls (n = 698) had significantly higher rates of anxiety, depression, and sleep disorders (29.8%, 31.2%, and 33.2% vs 16.1%, 17.3%, and 19.2%, respectively [all P < .001]); a lower Short Form-36 v2 mental component summary score (44.5 vs 48.0, respectively [P < .001]); a lower physical component summary score (47.6 vs 49.5, respectively [P = .004]), and lower health utilities (0.67 vs 0.72, respectively [P < .001]) in addition to a higher work absenteeism rate (9.9% vs 3.6%, respectively [P < .001]) and activity impairment rate (33.6% vs 25.2%, respectively [P < .001]). Subjects with AD and psoriasis controls (n = 260 each) showed similar impairment in health-related quality of life and productivity. LIMITATIONS: Data were self-reported. CONCLUSION: AD is associated with a substantial humanistic burden that is similar in magnitude to that of psoriasis, which is also recognized for its debilitating symptoms, indicating the need for more effective treatments for AD.

Antidepressant treatment patterns and costs among US employees.

OBJECTIVE: To compare medical and cost profiles of patients treated for depression classified by treatment pattern groups. METHODS: An analysis used de-identified 1999-2004 employer claims data (n=2.9 million beneficiaries) for employees with > or =1 diagnosis of major depressive disorder and > or =1 antidepressant prescription, following a 6-month washout period of no antidepressant prescription. Patients were classified into switcher/discontinuer/augmenter/maintainer during Healthcare Effectiveness Data and Information Set-defined initial and subsequent treatment periods, then grouped into stable, intermediate, or non-stable treatment groups, based on stability of treatment patterns. Medical/cost profiles for 6-month pre- and 12-month post-index periods were compared descriptively, and multivariate regressions were estimated, controlling for baseline characteristics/severity markers. Cost savings reflect differences between treatment pattern groups from a current US perspective. RESULTS: Of the 5,225 patients meeting inclusion criteria, 60.8% were in stable, 24.5% in intermediate and 14.7% in non-stable treatment groups. No significant differences existed in medical profiles and costs between the three groups in the pre-index period. In the post-index period, stable group patients had lower costs compared to intermediate and non-stable groups. Stable group patients generated cost savings of $1,842 compared to intermediate and $5,231 compared to non-stable groups. Multivariate analysis confirmed these findings. CONCLUSION: Patients on a more stable treatment regimen yield significant cost savings compared to patients on a less stable regimen.
