Project description:Rationale: Despite effective treatments, a large proportion of patients with asthma do not achieve sustained asthma control. The "preventable" burden associated with lack of proper control is likely taking a high toll at the personal and population level.Objectives: We predicted the future excess health and economic burden associated with uncontrolled asthma among American adolescents and adults for the next 20 years.Methods: We built a probabilistic model that linked state-specific estimates of population growth, aging, asthma prevalence, and asthma control levels. We conducted several meta-analyses to estimate the adjusted differences in healthcare resource use, quality-adjusted life years (QALYs), and productivity loss across control levels. We projected, nationally and at the state level, total direct and indirect (due to productivity loss) costs (in 2018 dollars) and QALYs lost because of uncontrolled asthma from 2019 to 2038.Measurements and Main Results: Total 20-year direct costs associated with uncontrolled asthma are estimated to be $300.6 billion (95% confidence interval [CI], $190.1 billion-411.1 billion). When indirect costs are added, total economic burden will be $963.5 billion (95% CI, $664.1 billion-1,262.9 billion). American adolescents and adults will lose an estimated 15.46 million (95% CI, 12.77 million-18.14 million) QALYs over this period because of uncontrolled asthma. Across states, the average 20-year per capita costs due to uncontrolled asthma ranged from $2,209 (Arkansas) to $6,132 (Connecticut).Conclusions: The burden of uncontrolled asthma is substantial and will continue to grow. Given that a substantial fraction of this burden is preventable, better adherence to evidence-informed asthma management strategies by care providers and patients has the potential to substantially reduce costs and improve quality of life.

Project description:The study was conducted to estimate the relative cost effectiveness of contraceptives in the United States from a payer's perspective.A Markov model was constructed to simulate costs for 16 contraceptive methods and no method over a 5-year period. Failure rates, adverse event rates and resource utilization were derived from the literature. Sensitivity analyses were performed on costs and failure rates.Any contraceptive method is superior to "no method". The three least expensive methods were the copper-T intrauterine device (IUD) (US$647), vasectomy (US$713) and levonorgestrel (LNG)-20 intrauterine system (IUS) (US$930). Results were sensitive to the cost of contraceptive methods, the cost of an unintended pregnancy and plan disenrollment rates.The copper-T IUD, vasectomy and the LNG-20 IUS are the most cost-effective contraceptive methods available in the United States. Differences in method costs, the cost of an unintended pregnancy and time horizon are influential factors that determine the overall value of a contraceptive method.

Project description:BackgroundWorldwide, asthma is a leading cause of morbidity, mortality and economic burden, with significant gender and racial disparities. However, little attention has been given to the independent role of age on lifetime asthma severity and hospitalization. We aimed to assess the effect of age, gender, race and ethnicity on indicators of asthma severity including asthma related hospitalization, mortality, hospital cost, and the rate of respiratory failure.MethodsWe analyzed the 2011 and 2012 Healthcare Cost and Utilization Project- National Inpatient Sample (NIS). We validated and extended those results using the National Heart, Lung, and Blood Institute-Severe Asthma Research Program (SARP; 2002-2011) database. Severe asthma was prospectively defined using the stringent American Thoracic Society (ATS) definition.ResultsHospitalization for asthma was reported in 372,685 encounters in 2012 and 368,528 in 2011. The yearly aggregate cost exceeded $2 billion. There were distinct bimodal distributions for hospitalization age, with an initial peak at 5 years and a second at 50 years. Likewise, this bimodal age distribution of patients with severe asthma was identified using SARP. Males comprised the majority of individuals in the first peak, but women in the second. Aggregate hospital cost mirrored the bimodal peak distribution. The probability of respiratory failure increased with age until the age of 60, after which it continued to increase in men, but not in women.ConclusionsSevere asthma is primarily a disease of young boys and middle age women. Greater understanding of the biology of lung aging and influence of sex hormones will allow us to plan for targeted interventions during these times in order to reduce the personal and societal burdens of asthma.

Project description:Objective: According to the National Asthma Education and Prevention Program (NAEPP), self-management education is an integral component of effective asthma care and should be offered to every patient with asthma. To estimate the proportion of persons with work-related asthma (WRA) who received asthma self-management education.Methods: A cross-sectional analysis of 2012-2014 Behavioral Risk Factor Surveillance System Asthma Call-back Survey data was conducted among ever-employed adults (≥18 years) with current asthma from 31 states and the District of Columbia.Results: Adults with WRA were significantly more likely than those with non-WRA to have ever taken a course to manage their asthma (15.7% versus 6.5%; PR = 2.1), been given an asthma action plan (43.5% versus 26.1%; PR = 1.7), shown how to use an inhaler (97.2% versus 95.8%; PR = 1.0), taught how to recognize early symptoms of an asthma episode (79.4% versus 64.1%; PR = 1.2), taught what to do during an asthma episode (86.4% versus 76.3%; PR = 1.1), taught how to use a peak flow meter to adjust daily medications (57.9% versus 41.7%; PR = 1.3), and advised to change things in home, school, or work (56.9% versus 30.4%; PR = 2.0). Moreover, targets for corresponding Healthy People 2020 respiratory disease objectives were met only among adults with WRA.Conclusions: Although adults with WRA were more likely to have received asthma self-management education, results suggest missed opportunities to provide asthma self-management education. Every healthcare visit should be used as an opportunity to discuss asthma self-management.

Project description:Congenital laryngomalacia is the most common cause of stridor in infants and usually resolves without therapy by 12-18?months of age. However, a recent study found that laryngomalacia may leave structural and functional traces with increased risk of later respiratory symptoms, suggesting that late-onset laryngomalacia may represent long-term consequences of milder or even undiagnosed forms. Unusual cases demonstrated that inspiratory stridor developed subsequent to upper respiratory tract infections. The lack of airway hyperresponsiveness in adulthood also raised questions regarding the diagnosis of childhood asthma. Laryngomalacia should be distinguished from severe asthma.

Project description:We describe a simplified model, based on the current economic and health effects of human papillomavirus (HPV), to estimate the cost-effectiveness of HPV vaccination of 12-year-old girls in the United States. Under base-case parameter values, the estimated cost per quality-adjusted life year gained by vaccination in the context of current cervical cancer screening practices in the United States ranged from $3,906 to $14,723 (2005 US dollars), depending on factors such as whether herd immunity effects were assumed; the types of HPV targeted by the vaccine; and whether the benefits of preventing anal, vaginal, vulvar, and oropharyngeal cancers were included. The results of our simplified model were consistent with published studies based on more complex models when key assumptions were similar. This consistency is reassuring because models of varying complexity will be essential tools for policy makers in the development of optimal HPV vaccination strategies.

Project description:BackgroundFrom 2003 to 2015, only 1 biologic was approved for the treatment of moderate to severe asthma in the United States. Since 2015, 4 new asthma biologics were approved by the US Food and Drug Administration.ObjectiveTo describe trends and disparities of asthma biologic use in the United States from 2003 to 2018.MethodsWe conducted a retrospective analysis using a cohort developed from the OptumLabs Data Warehouse. Prevalent and incident asthma biologic users were identified, and characteristics of users and nonusers were analyzed using regression analysis. Clinician prescribing behavior was described.ResultsUse of biologic medications remains uncommon among individuals with asthma, with prevalence peaking in 2006 at 3 in 1000 individuals with asthma. Several factors are associated with a higher likelihood of asthma biologic use: middle age, higher income, commercial insurance, and access to a specialist. Most clinicians (65%) in the cohort prescribed only 1 biologic.ConclusionsWe report low overall use of asthma biologics and evidence of disparities in access to asthma biologics.
