Trends in bronchiectasis among medicare beneficiaries in the United States, 2000 to 2007.

ABSTRACT: Bronchiectasis is a potentially serious condition characterized by permanent and abnormal widening of the airways, the prevalence of which is not well described. We sought to describe the trends, associated conditions, and risk factors for bronchiectasis among adults aged ? 65 years.A 5% sample of the Medicare outpatient claims database was analyzed for bronchiectasis trends among beneficiaries aged ? 65 years from 2000 to 2007. Bronchiectasis was identified using International Classification of Diseases, Ninth Revision, Clinical Modification claim diagnosis codes for acquired bronchiectasis. Period prevalence was used to describe sex- and race/ethnicity-specific rates, and annual prevalence was used to describe trends and age-specific rates. We estimated trends using Poisson regression and odds of bronchiectasis using multivariate logistic regression.From 2000 to 2007, 22,296 people had at least one claim for bronchiectasis. The 8-year period prevalence of bronchiectasis was 1,106 cases per 100,000 people. Bronchiectasis increased by 8.7% per year. We identified an interaction between the number of thoracic CT scans and race/ethnicity; period prevalence varied by a greater degree by number of thoracic CT scans among Asians compared with whites or blacks. Among people with one CT scan, Asians had a 2.5- and 3.9-fold higher period prevalence compared with whites and blacks.Bronchiectasis prevalence increased significantly from 2000 to 2007 in the Medicare outpatient setting and varied by age, sex, and race/ethnicity. This increase could be due to a true increase in the condition or an increased recognition of previously undiagnosed cases.

<h4>Background</h4>Bronchiectasis is a potentially serious condition characterized by permanent and abnormal widening of the airways, the prevalence of which is not well described. We sought to describe the trends, associated conditions, and risk factors for bronchiectasis among adults aged ≥ 65 years.<h4>Methods</h4>A 5% sample of the Medicare outpatient claims database was analyzed for bronchiectasis trends among beneficiaries aged ≥ 65 years from 2000 to 2007. Bronchiectasis was identified us ...[more]

Project description:ObjectivesTo analyze patterns of critical care medicine beds, use, and costs in acute care hospitals in the United States and relate critical care medicine beds and use to population shifts, age groups, and Medicare and Medicaid beneficiaries from 2000 to 2010.DesignRetrospective study of data from the federal Healthcare Cost Report Information System, American Hospital Association, and U.S. Census Bureau.SubjectsNone.InterventionsNone.SettingAcute care U.S. hospitals with critical care medicine beds.Measurements and main resultsFrom 2000 to 2010, U.S. hospitals with critical care medicine beds decreased by 17% (3,586-2,977), whereas the U.S. population increased by 9.6% (282.2-309.3M). Although hospital beds decreased by 2.2% (655,785-641,395), critical care medicine beds increased by 17.8% (88,235-103,900), a 20.4% increase in the critical care medicine-to-hospital bed ratio (13.5-16.2%). There was a greater percentage increase in premature/neonatal (29%; 14,391-18,567) than in adult (15.9%; 71,978-83,417) or pediatric (2.7%; 1,866-1,916) critical care medicine beds. Hospital occupancy rates increased by 10.4% (58.6-64.6%), whereas critical care medicine occupancy rates were stable (range, 65-68%). Critical care medicine beds per 100,000 total population increased by 7.4% (31.3-33.6). The proportional use of critical care medicine services by Medicare beneficiaries decreased by 17.3% (37.9-31.4%), whereas that by Medicaid rose by 18.3% (14.5-17.2%). Between 2000 and 2010, annual critical care medicine costs nearly doubled (92.2%; $56-108 billion). In the same period, the proportion of critical care medicine cost to the gross domestic product increased by 32.1% (0.54-0.72%).ConclusionsCritical care medicine beds, use, and costs in the United States continue to rise. The increasing use of critical care medicine by the premature/neonatal and Medicaid populations should be considered by healthcare policy makers, state agencies, and hospitals as they wrestle with critical care bed growth and the associated costs.

Project description:ImportanceNotable increases in mortality from alcohol-induced causes over the past 2 decades in the United States have been reported. However, comprehensive assessments of trends in alcohol-induced mortality by sex, age, race/ethnicity, and social and geographic factors are lacking.ObjectiveTo examine trends in alcohol-induced mortality rates from 2000 to 2016, comparing results by demographic characteristics including sex, race/ethnicity, age, county-level socioeconomic status, and geographic location.Design, setting, and participantsThis serial cross-sectional study used US national vital statistics data for years 2000 to 2016 for all US residents older than 15 years. Data analysis was conducted from January to September 2019.ExposuresTrends in alcohol-induced mortality by sex, race/ethnicity, age, county-level socioeconomic status (ie, median income, percentage of unemployed residents, percentage of residents with a bachelor's degree), rurality level, and US state.Main outcomes and measuresAlcohol-induced mortality, ie, deaths for which alcohol holds a population-attributable fraction of 1. Deaths were expressed per 100 000 residents as absolute and age-standardized rates. Mortality trends were measured as average annual percentage changes (AAPCs) for the entire period (ie, 2000-2016) and annual percentage changes (APCs) for individual periods of change within the study period.ResultsA total of 425 045 alcohol-induced deaths were identified from 2000 to 2016 (2000: 19 627 deaths; 14 979 [76.3%] men; 2016: 34 857 deaths; 25 213 [73.3%] men). The rate of alcohol-induced deaths increased substantially among men (AAPC, 1.4%; 95% CI, 1.0% to 1.8%) and women (AAPC, 3.1%; 95% CI, 2.6% to 3.6%) and accelerated recently (men, 2012-2016: APC, 4.2%; 95% CI, 3.1% to 5.3%; women, 2013-2016: APC, 7.1%; 95% CI, 5.1% to 9.1%). The largest increases by race/ethnicity were observed among American Indian and Alaska Native men (AAPC, 3.3%; 95% CI, 2.6% to 4.0%), American Indian and Alaska Native women (AAPC, 4.2%; 95% CI, 3.8% to 4.6%), and white women (AAPC, 4.1%; 95% CI, 3.6% to 4.7%). Despite initial declines among black women, black men, and Latino men (eg, Latino men, 2000-2003: APC, -5.1%; 95% CI, -9.8% to -0.1%; 2003-2013: APC, -0.6%; 95% CI, -1.4% to 0.2%), increases occurred later in the study period (eg, Latino men, 2013-2016: APC, 4.1%; 95% CI, 0.3% to 8.1%). The rates of increase varied by age group and in turn by racial/ethnic group. Among white individuals, large absolute increases occurred in midlife (eg, men aged 55-59 years, 2000-2003: 25.5 deaths per 100 000 residents; 2013-2016: 43.3 deaths per 100 000 residents; women aged 50-54 years, 2000-2003: 7.4 deaths per 100 000 residents; 2013-2016: 16.5 deaths per 100 000 residents), although APCs were also large for ages 25 to 34 years, ranging from 4.6% to 6.9% per year among men and from 7.3% to 12.0% among women. Among American Indian and Alaska Native individuals, increases throughout the age range were observed, with the largest absolute increase occurring for ages 45 to 49 years among men (2000-2013: 113.6 deaths per 100 000 residents; 2013-2016: 193.1 deaths per 100 000 residents) and for ages 50 to 54 among women (2000-2013: from 56.1 deaths per 100 000 residents; 2013-2016: 105.1 deaths per 100 000 residents).Conclusions and relevanceThis study found large increases in alcohol-induced death rates across age and racial/ethnic subgroups of the US population, which have accelerated over recent years. Large increases in alcohol-induced deaths among younger age groups may be associated with future increases in alcohol-related disease.
